The most prevalent disease-causing mutation of CFTR is the deletion of Phe508 (ΔF508), which leads to defects in conventional Golgi-mediated exocytosis and cell surface expression. We report that ΔF508-CFTR surface expression can be rescued in vitro and in vivo by directing it to an unconventional GRASP-dependent secretion pathway. An integrated molecular and physiological analysis indicates that mechanisms associated with ER stress induce cell surface trafficking of the ER core-glycosylated wild-type and ΔF508-CFTR via the GRASP-dependent pathway. Phosphorylation of a specific site of GRASP and the PDZ-based interaction between GRASP and CFTR are critical for this unconventional surface trafficking. Remarkably, transgenic expression of GRASP in ΔF508-CFTR mice restores CFTR function and rescues mouse survival without apparent toxicity. These findings provide insight into how unconventional protein secretion is activated, and offer a potential therapeutic strategy for the treatment of cystic fibrosis and perhaps diseases stemming from other misfolded proteins. © 2011 Elsevier Inc.

The TBVAC2020 proposal builds on the highly successful and long-standing collaborations in subsequent EC-FP5-, FP6- and FP7-funded TB vaccine and biomarker projects, but also brings in a large number of new key partners from excellent laboratories from Europe, USA, Asia, Africa and Australia, many of which are global leaders in the TB field. This was initiated by launching an open call for Expressions of Interest (EoI) prior to this application and to which interested parties could respond. In total, 115 EoIs were received and ranked by the TBVI Steering Committee using proposed H2020 evaluation criteria. This led to the prioritisation of 52 R&D approaches included in this proposal. TBVAC2020 aims to innovate and diversify the current TB vaccine and biomarker pipeline while at the same time applying portfolio management using gating and priority setting criteria to select as early as possible the most promising TB vaccine candidates, and accelerate their development. TBVAC2020 proposes to achieve this by combining creative bottom-up approaches for vaccine discovery (WP1), new preclinical models addressing clinical challenges (WP2) and identification and characterisation of correlates of protection (WP5) with a directive top-down portfolio management approach aiming to select the most promising TB vaccine candidates by their comparative evaluation using objective gating and priority setting criteria (WP6) and by supporting direct, head-to head or comparative preclinical and early clinical evaluation (WP3, WP4). This approach will both innovate and diversify the existing TB vaccine and biomarker pipeline as well as accelerate development of most promising TB vaccine candidates through early development stages. The proposed approach and involvement of many internationally leading groups in the TB vaccine and biomarker area in TBVAC2020 fully aligns with the Global TB Vaccine Partnerships (GTBVP).

Blue-Action will provide fundamental and empirically-grounded, executable science that quantifies and explains the role of a changing Arctic in increasing predictive capability of weather and climate of the Northern Hemisphere.To achieve this Blue-Action will take a transdisciplinary approach, bridging scientific understanding within Arctic climate, weather and risk management research, with key stakeholder knowledge of the impacts of climatic weather extremes and hazardous events; leading to the co-design of better services.This bridge will build on innovative statistical and dynamical approaches to predict weather and climate extremes. In dialogue with users, Blue-Arctic will take stock in existing knowledge about cross-sectoral impacts and vulnerabilities with respect to the occurrence of these events when associated to weather and climate predictions. Modeling and prediction capabilities will be enhanced by targeting firstly, lower latitude oceanic and atmospheric drivers of regional Arctic changes and secondly, Arctic impacts on Northern Hemisphere climate and weather extremes. Coordinated multi-model experiments will be key to test new higher resolution model configurations, innovative methods to reduce forecast error, and advanced methods to improve uptake of new Earth observations assets are planned. Blue-Action thereby demonstrates how such an uptake may assist in creating better optimized observation system for various modelling applications. The improved robust and reliable forecasting can help meteorological and climate services to better deliver tailored predictions and advice, including sub-seasonal to seasonal time scales, will take Arctic climate prediction beyond seasons and to teleconnections over the Northern Hemisphere. Blue-Action will through its concerted efforts therefore contribute to the improvement of climate models to represent Arctic warming realistically and address its impact on regional and global atmospheric and oceanic circulation.

With 14.4 million prevalent cases and 1.7 million deaths tuberculosis (TB) remains one of the most serious infectious diseases to date. An estimated 2 billion people are believed to be infected with Mycobacterium tuberculosis and at risk of developing disease. Multi- and extensively drug resistant strains are increasingly appearing in many parts of the world, including Europe. While with current control measures the Millennium Development Goals (MDGs) set for 2015 may be achieved, reaching these would still leave a million people per year dying from TB. Much more effective measures, particularly more effective vaccines will be essential to reach the target of eliminating TB in 2050. Two successive FP5 and FP6 funded projects, Tuberculosis (TB) Vaccine Cluster (2000-2003) and TBVAC (2004-2008), have in the recent decade made significant contributions to the global TB vaccine pipeline, with four vaccines (out of nine globally) being advanced to clinical stages. Both projects strongly contributed to the strengthening and integration of expertise and led to a European focus of excellence that is unique in the area of TB vaccine development. In order to sustain and accelerate the TB vaccine developments and unique integrated excellence of TBVAC, a specific legal entity was created named TuBerculosis Vaccine Initiative (TBVI). The NEWTBVAC proposal is the FP7 successor of TBVAC, and will be coordinated by TBVI. The proposal has the following objectives : 1) To sustain and innovate the current European pipeline with new vaccine discoveries and advance promising candidates to clinical stages; 2) To design new, second generation vaccines based new prime-boost strategies and/or new (combinations of) promising subunit vaccines, that will impact on reduction of disease in exposed individuals; 3) To sustain and innovate discovery, evaluation and testing of new biomarkers, that will be critically important for future monitoring of clinical trials.

Ultrasensitive detection of nanoscale particles has applications in important fields ranging from environmental monitoring to analysis of viral structures. However, it remains extremely difficult due to ultralow polarizabilities of small-sized, low-index particles. A team led by Professor Xiao Yun-Feng at Peking University, collaborating with Yonsei University of the Republic of Korea, demonstrated experimentally that the dissipative interaction in a high-Q optical microcavity allows the detection of single nanoparticles. This work has been published in the recent issue of Physical Review Applied. Over the past few years, high-Q optical microcavities have shown great potential in sensing applications due to the strongly enhanced light-matter interaction therein. The conventional sensing mechanism, however, has to rely on the reactive interaction. The reactive sensing is limited by the polarizability of the particle, and will fail its sensing function when the real part of the polarizability approaches zero. In the publication, the authors point out that the dissipative interaction opens a channel of the cavity mode decay and results in the resonance linewidth change, which forms an effective sensing scheme even when the real part of analyte polarizability approaches zero, because the signal magnitude is determined by the absorption loss and side scattering of the particle. In the experiment, detection of single gold nanorodsis used to assess the sensing performance. “The gold nanorod of the size of 40 nm × 16 nm is a perfect candidate to test the microcavity sensor for two reasons. One is that the polarizability of this nanoparticle can be tuned by varying the probe wavelength. The other is that the surface plasmon resonance of the particle of this dimension coincides with one of our probe wavelengths in the experiment, at which the real part of the polarizability become zero, most likely invalidating the reactive sensing method, but strengthening the dissipative one,” says Dr. Yanyan Zhi, post-doctor and one of the co-first authors of this work. The researchers examined experimentally both the reactive and dissipative sensing methods by monitoring the mode shift and the linewidth change of the high-Q cavity resonance, respectively. It was found that the reactive sensing signal cannot be recognized from the noises when the probe wavelength is on plasmonic resonance where the nanorod polarizability approaches zero, while the proposed dissipative sensing method still works well, which is consistent with the theoretical predictions. The anticipated detection limit can reach 13 nm × 5 nm, which is about 12 times smaller volume than that can be detected by the reactive sensing method. This dissipative sensing method not only provides a new physical mechanism of microcavity sensing, but also represents a significant step towards practical optical sensors in areas of analytical chemistry, environmental science, and molecular biology. “Practically, it’s ready that both the mode shift and the linewidth change of the cavity mode can be simultaneously measured, and thus the common reactive and the proposed dissipative sensing methods are compatible to each other,” says Xiao. “The combination of those two sensing methods adds new dimensions to what can be measured using each of the two methods alone. The dissipative sensing method using a high-Q microcavityoffers a great platform for the detection of tiny single particles, such as vital virus, particles in the polluted air, loss of particles in the manufacturing process, and other nanoparticles under interest.”

The gastroenterology ward at the Prince of Wales Hospital in Hong Kong has undergone a dramatic change under the watchful eyes of gastroenterologist Siew Ng and her colleagues. When Ng started seeing patients there nearly seven years ago, she mainly encountered infectious diseases such as intestinal tuberculosis that ravage the gastrointestinal tract. But today, the ward is overwhelmed by young men and women with inflammatory bowel disease (IBD), a lifelong gastrointestinal condition that can be debilitating if left untreated (see 'Preparing for the burden'). “I can hardly keep up with all the patients I have,” says Ng. “The number of cases is basically exploding. And she has the data to support this statement. Ng also leads the Asia-Pacific Crohn's and Colitis Epidemiology Study (ACCESS), which, for the past five years, has tracked new cases of Crohn's disease and ulcerative colitis — the two major forms of IBD — across 13 countries in Asia as well as Australia. The incidence of IBD in Hong Kong has grown from just 1 case in a million in 1985 to a little over 30 in every million in 2014 (ref. 1). In countries such as the United States, the United Kingdom and Canada, the rate of IBD is much higher, with roughly 200–300 cases per million people. In fact, for a long time after IBD was first reported in the United Kingdom in the mid-1800s, it was thought of as a disease of European ancestry. But with the condition now appearing all around the world, the consensus is that anyone can get IBD. “IBD really is a global disease now,” says Ashwin Ananthakrishnan, an epidemiologist and clinician at the Massachusetts General Hospital Crohn's and Colitis Center in Boston. “If you look at the sheer number of patients, there are probably more in India and China than in North America.” The continuing surge in cases is providing research opportunities for clinicians such as Ng. Like other immune-related disorders such as multiple sclerosis and psoriasis, the incidence of IBD has risen in parallel with industrialization and urbanization, but the environmental drivers of IBD are not well understood. As people flock to cities, they have access to better health care and sanitation, but they are also exposed to poorer air quality, and are more likely to have sedentary, largely indoor lifestyles and to consume convenience diets that are high in saturated fat. Studies have linked factors such as these with IBD, but it is difficult to determine the origin in regions that have a long history of the disease. The ideal time to tease apart the complex web of environmental triggers and genetic associations, says Ng, is as urbanization is happening and before the incidence of IBD has peaked. The extent of environmental change may correlate with IBD's rise and characteristics, and could lead to new hypotheses about the causes. “The golden time for finding the cause of the disease is the next ten years,” says Ng. More than 200 genetic variants have been associated with IBD. In the first genetic-association study of IBD to include multiple ethnic groups — Europeans, East Asians, Indians and Iranians — 38 new loci (regions of the genome) with links to IBD were uncovered, 25 of which have previously been associated with other diseases or traits, such as multiple sclerosis or levels of cholesterol2. But the rise of IBD in Asia is not being driven by the emergence of new mutations — genetic changes occur over a much longer timescale than the global onset of IBD has taken. That does not mean, however, that genetics has nothing to offer in the quest to understand the increase of incidence in Asia. Genetic variants could provide clues to why environmental changes have greater impacts on some populations than on others, says Ananthakrishnan. Punjab state in northern India, for instance, has one of the highest incidences of ulcerative colitis in Asia — around 6 new cases in 100,000 people per year3. And the incidence of IBD in people of Indian descent who live in Malaysia is six times higher than that in indigenous Malaysians, and three times higher than that in those of Chinese descent4; clearly, some genetic risk factor is at play. Not all the genes or variants present the same risk across the globe. For example, the ATG16L1 gene — involved in the cellular recycling process autophagy — is associated with risk of Crohn's in white populations, but is not implicated in IBD in Asian people. And NOD2, a risk gene in individuals of European ancestry that is also connected with more aggressive forms of the disease, harbours different IBD-linked variants in Asian populations. What's more, the degree to which these genes explain the disease varies between different populations. In Asia, only 3% of people with IBD have a close relative with the disease, compared with 15% of individuals in the West5. As well as overall risk, certain gene variants may also correlate with particular presentations of IBD, Ananthakrishnan says. His work, which focuses on the environmental and genetic factors associated with IBD, suggests that an Indian person living in the West, for example, will have a type of Crohn's that is more similar to that seen in India than to cases in the West. Genetic and microbial data from different populations can also be used to help tailor treatments for people with IBD, says Jae Hee Cheon at Yonsei University College of Medicine in Seoul, who has conducted genetic, microbiome and epidemiological research in Koreans with IBD. For instance, the microbiota pills in development, which researchers hope to use to replace a pathogenic gut bacterial community with a healthy one, will not necessarily work for patients across the globe because patient populations vary in their disease features and response to treatment, he says. And finding the relevant genetic variants in smaller Asian countries is difficult, partly because the disease is still relatively rare. In Malaysia, for example, only about 2,000–3,000 people are thought to have IBD. That makes genome-wide association studies, which need many thousands of cases, nigh on impossible. The next best option for researchers is to pick handfuls of genetic variants identified as risk factors in larger studies, such as those done in the West, and test to see whether these variants pose a risk in smaller groups, says gastroenterologist Ida Hilmi at the University of Malaya in Kuala Lumpur. Risk factors One of the biggest questions Ananthakrishnan fields from people with IBD is how they can prevent their children from developing the disease. “It's a question that all of us working in the environmental-influence space want to answer,” he says. But at the moment, he can offer only a few general recommendations: avoid passive smoking, minimize antibiotic exposure in the early years and avoid giving children non-steroidal anti-inflammatory drugs, which can irritate the gut. For the most part, however, studies have shown these to be only risk factors, rather than proven interventions. Work to unpick the environmental factors behind IBD has a long way to go. Some of the clearest evidence for the role of the environment in IBD comes from studies of immigrants. For example, a large study of residents in Ontario, Canada, showed that South Asian immigrants have an incidence rate of roughly 70 new cases of IBD per million people per year6. Although that is still considerably lower than the annual rate for long-term residents of 240 per million, children of South Asian immigrants have an annual incidence rate that is nearly the same (60 per million) as the children of long-term residents (72 per million). One of the biggest surprises in this study was that the age at which immigrants arrive in Canada is a strong predictive factor for developing IBD, says paediatric gastroenterologist Eric Benchimol of the Children's Hospital of Eastern Ontario Research Institute in Ottawa, who led the study. For every decade older the person is when they arrive, the risk of IBD decreases by nearly 10%. This implies that there are factors in the new environment that, for certain genetic variations, increase the risk of IBD. Researchers suspect that the likeliest way the environment increases risk is by altering a person's gut bacteria. The main line of thought is that environmental triggers have a greater influence early in life, as the immune system and a full complement of gut bacteria develop and mature. “That's where the excitement is,” says Benchimol. Several large studies are under way in the United States and Canada to investigate the theory. In 2015, researchers at the University of Pennsylvania in Philadelphia showed that inflammation, antibiotic exposure and changes to diet independently alter the balance of gut microbes in children with Crohn's disease7. Treatment with a biological drug to decrease inflammation or dietary approaches seemed to normalize the composition of the microbiota. The ongoing Canadian Children Inflammatory Bowel Disease Network's CIDsCaNN study is collecting data from children with a new IBD diagnosis and following them for 18 months, including those with a South Asian background. Researchers are collecting stool samples to investigate the make-up of the microbiota, as well as recording information about early-life environmental risk factors, to try to understand what is triggering the disease. And a team at the University of Toronto in Canada is running a study called GEMINI (Generational Differences in Environmental Exposures caused by Migration: Impact on Incidence of Inflammatory Disease), to investigate risk factors in healthy first- and second-generation South Asian immigrants for IBD and other autoimmune diseases (such as type 1 diabetes and multiple sclerosis). Canada is the perfect place to conduct these studies, partly because its national-health registries make it easy to identify and track those with the disease, Benchimol says. Prospective studies such as CIDsCaNN, which follow individuals over time, are crucial for understanding the environmental factors that contribute to IBD. Ananthakrishnan is analysing data gathered through the Nurses' Health Study, a longitudinal study of more than 100,000 US women who have completed medical history and lifestyle questionnaires for decades. He found that women who ate high levels of fibre — about 24 grams per day — in the form of fruits and vegetables, were 40% less likely to get Crohn's disease than women who ate around half that8. Other studies have found similar trends for ulcerative colitis. High fibre intake has also been shown to prevent relapse in people with IBD, and animal models of IBD support the role of fibre in reducing the inflammatory damage wrought by the disease. Taken together, the move from a high-fibre diet towards a low-fibre Western diet, which seems to be happening in Asian cities in particular, might be part of the reason for the rise in IBD, Ananthakrishnan says. One limitation to applying findings from Western studies, such as the Nurses' Health Study, to what is happening in Asia is that participants are mainly of European ancestry. Although some factors, such as breastfeeding, seem to be universally protective, other environmental factors do not always carry the same weight across different ethnicities. Smoking, for instance, is one of the strongest risk factors for Crohn's disease in Western populations, but this was not the case for Asian participants in Ng's ACCESS cohort. ACCESS data also seem to suggest that antibiotic use — thought to be a risk factor in the West — is protective against IBD in Asian populations. But it can be more difficult to decipher relationships between antibiotic use and IBD in Asia, because the drugs can be bought over the counter in some countries, making it difficult to accurately record their use. To get to the heart of why the incidence of IBD in Asia is on the rise, rigorous studies based in the continent are needed. Ananthakrishnan thinks that the data sets gathered in the West are excellent models for understanding how environmental risk factors affect chronic disease. Researchers can use these both to narrow the scope of the exposure data and determine when and how often data are collected in Asian epidemiological studies of IBD, says gastroenterologist and epidemiologist Gilaad Kaplan of the University of Calgary in Canada. Ng and her collaborators are pursuing several lines of research as the incidence in Asia swells and their golden window of opportunity to identify the triggers begins to diminish. She is planning to compare the urban and rural populations of China, which are ethnically similar, but starkly different in their environmental exposures — from their dietary choices to whether they use flush toilets. Targeting areas in China that have a low incidence of IBD, such as Xiangshan County in Zhejiang and Chengdu, may help to uncover genetic and environmental factors that protect some individuals from the disease. Much research needs to be done, Ng says. “Every day, I go to work and I see new cases being referred, and I ask my colleague, 'Why has this disease dropped from the sky, out of nowhere? Where did it come from?” Researchers know that the best chance to find out is now.

The Opening Ceremony was held at the Diaoyutai State Guesthouse. Addressing the Opening ceremony, Peking University President Professor Lin Jianhua said, “For universities in the Chinese mainland, we have a commitment to take on the responsibility for the society, the nation and the world. Peking University has inherited and has been diligently following this tradition. On the one hand, we teach students to bear social responsibility during their studies and after graduation. On the other hand, the Universities have to bear their responsibility for the community, the region, and the nation, during their course of development and advancement.” Professor Lin added, “This is a difficult mission, and it calls for concerted efforts of higher education leaders.” Speaking at the Opening Ceremony, PolyU President Professor Timothy W. Tong said, “Over the last few decades, global challenges such as economic development, environmental protection and technological innovation have driven universities worldwide to redefine their roles and responsibilities beyond traditional education and research in order to bolster their impact on society. Consequently, social responsibility has become a subject high on the agenda.” Professor Tong added, “The USR Network member universities sharing the same vision of making our world increasingly just, inclusive, peaceful and sustainable.

Torrance dentists at Blue Sky Family Dental are now offering orthodontic treatment options with braces and Invisalign. Properly aligned teeth are important for clear speech, comfortable eating, and proper oral aesthetics. Proper orthodontic treatment can ensure the bite is well-balanced and the teeth are aligned. Braces are the traditional orthodontic treatment. Most patients recognize them as metal brackets and wires, but modern braces have come a long way from the bulky braces of the past with sleeker, more comfortable components. Invisalign is a more technologically advanced option, but works using many of the same principals of braces. Instead of metal wires, Invisalign uses clear aligners that apply pressure to certain points to move teeth. Both treatments can be used to treat: “The high-end technology that is available today enables me to give you an amazing, healthy smile,” said Dr. Mondavi. “Because my staff and I are trained yearly on the newest, most advanced procedures, I’m able to exceed patients’ expectations.” Along with orthodontic treatments, Dr. Mondavi and the team at Blue Sky Family Dental offer restorative dentistry, crowns and bridges, inlays and onlays, dental implants, dentures, bruxism and athletic mouth guards, root canals, pediatric dental care, dental veneers, and smile makeovers. Dr. Robert Mondavi is a graduate of the University of the Pacific in San Francisco. He continues to take advanced courses to advance his knowledge, including advanced cosmetic dentistry training and advanced implant training.

Home > Press > Unmasking new drivers of stomach cancer: Study advances understanding of stomach cancer progression and could lead to new therapeutic targets and improved clinical outcomes Abstract: Scientists have uncovered a new class of master control elements in stomach cancer called super-enhancers, which control critical cancer genes and proteins required for stomach tumours to survive and grow. The teams generation of this unprecedented and comprehensive catalogue of stomach cancer super-enhancers is an important milestone for the community. Currently, stomach cancer is the fifth most common cancer worldwide and the third leading cause of global cancer death. Most gastric cancers are diagnosed late, and the disease is often resistant to current clinical treatments. By studying super-enhancers in stomach tumours, the team was able to shed light on how these elements impact the risk of stomach cancer development and progression of the disease. For example, stomach cancer patients whose tumours exhibited high numbers of super-enhancers exhibited a significantly poorer survival rate. Selective activation of these super-enhancers could explain why certain groups of people are at risk of developing the disease. These tissue-specific super-enhancers also represent a previously untapped reservoir of cancer vulnerability, acting to bridge oncogenic signalling to tissue-specific features of malignancy. Thus, studying the mechanisms driving the development of super-enhancers in stomach cancer may lead to novel therapies. Specifically, the team also identified two DNA-binding proteins as drivers for the formation of tumour-specific super-enhancers. These may serve as potential drug targets for stomach cancer. The researchers were able to make this finding using a highly sensitive, made-in-Singapore technology, called Nano-ChIPseq. Developed at A*STARs Genome Institute of Singapore (GIS), Nano-ChIPseq enables the study of epigenomic changes in clinical samples obtained directly from stomach cancer patients, rather than laboratory cultured cell lines. Unlike DNA which is stable and unchanging, epigenomic instructions are strongly influenced by factors such as food, infectious agents, and chemicals, suggesting that they can be modified by environmental risk factors. The team is now working to commercialise the technology and develop data technologies, which will enable scientists to revolutionise cancer therapeutics. Future work in our lab will investigate how such super-enhancers can be disrupted by drugs, which will open up new avenues for cancer therapy, said the studys corresponding author Prof Patrick Tan, Deputy Executive Director of A*STARs Biomedical Research Council and an associate faculty member at the GIS. We hope that our findings will encourage the scientific community to embrace our technology as a means to rapidly uncover master control elements that are highly relevant to diseases and clinical outcomes. This effort may eventually change the way stomach and other cancers are managed, which will enhance the clinical outcomes of cancer patients. Published in scientific journal Nature Communications, this study was led by GIS, in collaboration with Duke-NUS Medical School, Cancer Science Institute of Singapore at the National University of Singapore (NUS), Singapore General Hospital (SGH), Weatherall Institute of Molecular Medicine at Oxford University, and the Singapore Gastric Cancer Consortium (SGCC). Commercialisation of the Nano-ChIPseq platform is currently supported through gap funding awarded by ETPL Pte Ltd, the commercialisation arm of A*STAR. "I felt something awesome will be coming when I heard about the new method, Nano-ChIPseq. The study suggests that extensive alterations in gene regulation, and not genes themselves, explain deep mysteries of gastric cancer, which are known to exhibit small numbers of mutations and deep involvement of bacterial infection, an environmental factor. Naturally, development of novel therapeutic strategies must take account of these findings," said Dr Toshikazu Ushijima, Chief of Division of Epigenomics at the National Cancer Center Research Institute in Japan, and a member of the SGCC Scientific Advisory Board. GIS Executive Director Prof Ng Huck Hui added, This is a remarkable technological breakthrough for the community. As we constantly work to find better treatments for cancer, it is also important that we find more efficient ways to study how epigenomic changes can drive the formation of cancerous cells from healthy cells. A greater understanding about molecular changes in diseases can potentially lead to early therapeutic intervention and improved care for the patients. 1Cancer Therapeutics and Stratified Oncology, Genome Institute of Singapore, 60 Biopolis Street, Genome #02-01, Singapore 138672, Singapore. 2Cancer and Stem Cell Biology Program, Duke-NUS Graduate Medical School, 8 College Road, Singapore 169857, Singapore. 3NUS Graduate School for Integrative Sciences and Engineering, National University of Singapore, 5 Lower Kent Ridge Road, Singapore 119074, Singapore. 4Cancer Science Institute of Singapore, National University of Singapore, 14 Medical Drive, #12-01, Singapore 117599, Singapore. 5Department of Physiology, Yong Loo Lin School of Medicine, National University of Singapore, 2 Medical Drive #04-01, Singapore 117597, Singapore. 6Department of Human Genetics, Genome Institute of Singapore, 60 Biopolis Street, Genome #02-01, Singapore 138672, Singapore. 7Medical Research Council (MRC) Molecular Haematology Unit, Weatherall Institute of Molecular Medicine, Oxford University, Oxford OX3 9DS, UK. 8Department of Upper Gastrointestinal & Bariatric Surgery, Singapore General Hospital, Singapore 169608, Singapore. 9Division of Surgical Oncology, National Cancer Centre Singapore, 11 Hospital Drive, Singapore 169610, Singapore. 10Department of General Surgery, Singapore General Hospital, Singapore 169608, Singapore. 11Department of Medical Oncology, Yonsei University College of Medicine, Seoul 120-752, South Korea. 12SingHealth/Duke-NUS Institute of Precision Medicine, National Heart Centre Singapore, Singapore 168752, Singapore. 13Laboratory of Cancer Epigenome, Department of Medical Sciences, National Cancer Centre, 11 Hospital Drive, Singapore 169610, Singapore. 14School of Biological Sciences, Nanyang Technological University, Singapore 637551, Singapore. 15Cellular and Molecular Research, National Cancer Centre, 11 Hospital Drive, Singapore 169610, Singapore. *These authors contributed equally to this work.

Home > Press > Penn engineers develop first transistors made entirely of nanocrystal 'inks Abstract: The transistor is the most fundamental building block of electronics, used to build circuits capable of amplifying electrical signals or switching them between the 0s and 1s at the heart of digital computation. Transistor fabrication is a highly complex process, however, requiring high-temperature, high-vacuum equipment. Now, University of Pennsylvania engineers have shown a new approach for making these devices: sequentially depositing their components in the form of liquid nanocrystal "inks." Their new study, published in Science, opens the door for electrical components to be built into flexible or wearable applications, as the lower-temperature process is compatible with a wide array of materials and can be applied to larger areas. The researchers' nanocrystal-based field effect transistors were patterned onto flexible plastic backings using spin coating but could eventually be constructed by additive manufacturing systems, like 3-D printers. The study was lead by Cherie Kagan, the Stephen J. Angello Professor in the School of Engineering and Applied Science, and Ji-Hyuk Choi, then a member of her lab, now a senior researcher at the Korea Institute of Geoscience and Mineral Resources. Han Wang, Soong Ju Oh, Taejong Paik and Pil Sung Jo of the Kagan lab contributed to the work. They collaborated with Christopher Murray, a Penn Integrates Knowledge Professor with appointments in the School of Arts & Sciences and Penn Engineering; Murray lab members Xingchen Ye and Benjamin Diroll; and Jinwoo Sung of Korea's Yonsei University. The researchers began by taking nanocrystals, or roughly spherical nanoscale particles, with the electrical qualities necessary for a transistor and dispersing these particles in a liquid, making nanocrystal inks. Kagan's group developed a library of four of these inks: a conductor (silver), an insulator (aluminum oxide), a semiconductor (cadmium selenide) and a conductor combined with a dopant (a mixture of silver and indium). "Doping" the semiconductor layer of the transistor with impurities controls whether the device transmits a positive or negative charge. "These materials are colloids just like the ink in your inkjet printer," Kagan said, "but you can get all the characteristics that you want and expect from the analogous bulk materials, such as whether they're conductors, semiconductors or insulators. "Our question was whether you could lay them down on a surface in such a way that they work together to form functional transistors." The electrical properties of several of these nanocrystal inks had been independently verified, but they had never been combined into full devices. "This is the first work," Choi said, "showing that all the components, the metallic, insulating, and semiconducting layers of the transistors, and even the doping of the semiconductor could be made from nanocrystals." Such a process entails layering or mixing them in precise patterns. First, the conductive silver nanocrystal ink was deposited from liquid on a flexible plastic surface that was treated with a photolithographic mask, then rapidly spun to draw it out in an even layer. The mask was then removed to leave the silver ink in the shape of the transistor's gate electrode. The researchers followed that layer by spin-coating a layer of the aluminum oxide nanocrystal-based insulator, then a layer of the cadmium selenide nanocrystal-based semiconductor and finally another masked layer for the indium/silver mixture, which forms the transistor's source and drain electrodes. Upon heating at relatively low temperatures, the indium dopant diffused from those electrodes into the semiconductor component. "The trick with working with solution-based materials is making sure that, when you add the second layer, it doesn't wash off the first, and so on," Kagan said. "We had to treat the surfaces of the nanocrystals, both when they're first in solution and after they're deposited, to make sure they have the right electrical properties and that they stick together in the configuration we want." Because this entirely ink-based fabrication process works at lower temperatures than existing vacuum-based methods, the researchers were able to make several transistors on the same flexible plastic backing at the same time. "Making transistors over larger areas and at lower temperatures have been goals for an emerging class of technologies, when people think of the Internet of things, large area flexible electronics and wearable devices," Kagan said. "We haven't developed all of the necessary aspects so they could be printed yet, but because these materials are all solution-based, it demonstrates the promise of this materials class and sets the stage for additive manufacturing." ### The research was supported primarily by the National Science Foundation through its Materials Research Science and Engineering Centers Award DMR-1120901 and its Chemical, Bioengineering, Environmental and Transport Systems Award CBET-1236406; the U.S. Department of Energy, Office of Basic Energy Sciences, Division of Materials Science and Engineering Award DE-SC0002158; and the Office of Naval Research Multidisciplinary University Research Initiative Award ONR-N00014-10-1-0942.

Dublin, Dec. 20, 2016 (GLOBE NEWSWIRE) -- Research and Markets has announced the addition of the "HDAC Inhibitors Market, 2016 - 2026" report to their offering. The HDAC Inhibitors Market, 2016-2026 report was commissioned to examine the current landscape and the future outlook of the growing pipeline of products in this area. HDACs have been studied in cellular processes such as apoptosis, autophagy, metabolism, DNA damage repair, cell cycle control and senescence. Altered expression of HDACs has been observed in different tumors; this makes them a potential target for treatment of cancer and other genetic or epigenetic related disorders. Inhibition of HDACs has shown positive results in disruption of multiple cell signaling pathways and prevention of tumor growth. The study provides a detailed market forecast and opportunity analysis for the time period 2016-2026. The research, analysis and insights presented in this report include potential sales of the approved drugs and the ones in late stages of development (phase III and phase II). To add robustness to our model, we have provided three scenarios for our market forecast; these include the conservative, base and optimistic scenarios. Our opinions and insights, presented in this study were influenced by several discussions we conducted with experts in this area. All actual figures have been sourced and analyzed from publicly available information forums and primary research discussions. Financial figures mentioned in this report are in USD, unless otherwise specified. Example Highlights - Nearly 90 HDAC inhibitors are currently in clinical / preclinical stages of development; the clinical molecules account for over 30% of the pipeline while over 60% is captured by molecules in the preclinical / discovery stage. - With 66% of the pipeline molecules targeting oncological indications, cancer remains one of the most widely studied field for HDAC inhibitors. Within oncology, hematological malignancies such as PTCL and CTCL are popular targets; three HDAC inhibitors (Zolinza, ISTODAX® and BELEODAQ®) are approved for these indications. Other therapeutic areas such as autoimmune disorders, infectious diseases, inflammatory disorders, neurological disorders, are also gradually gaining traction. - Although the market was initially led by the large-size pharma players (such as Celgene, Merck, Novartis), the current market is characterized by the presence of several small / mid-sized pharma players. Notable examples of the small and mid-sized firms include 4SC, Chroma Therapeutics, CrystalGenomics, Curis, Evgen Pharma, FORUM Pharmaceuticals, Karus Therapeutics, Mirati Therapeutics, MEI Pharma, Shenzhen Chipscreen Biosciences, Syndax Pharmaceuticals and TetraLogic Pharmaceuticals. - In addition, there are several non-industry institutes and universities that are primarily carrying out preclinical research. Examples of these include Harvard Medical School (BG45), Imperial College London (C1A), Kyoto University (Jd, Sd), National Taiwan University (Quinazolin-4-one derivatives), Taipei Medical University (MPT0E028), University of Messina (MC-1575, MC-1568). - Four of the five approved drugs are pan-HDAC inhibitors targeting HDAC isoforms non-specifically. However, in the past few years, several class selective HDAC inhibitors have entered the clinic; these are associated with a higher efficacy and result in decreased toxicity from the treatment. Of the total HDAC inhibitors identified, 52% of the molecules are class specific; of these, 33% molecules target Class I specific isoforms and the rest target Class II specific isoforms of HDACs. Notable examples of molecules targeting class-specific HDACs includeentinostat (phase III), resminostat (phase II), SHP-141 (phase II), mocetinostat (phase II), CHR-3996 (phase I/II) and ricolinostat (phase I/II). - The HDAC inhibitors market is expected to grow at a healthy annual rate of 32% over the next decade.With multiple potential target indications, Istodax® is expected to capture the largest market share (close to 21%) in 2026, followed by entinostat, Farydak® and Beleodaq®.

The need for the radio spectrum for the rapidly growing broadband access services is evident. Abundant and fast access to spectrum has three main advantages: it fosters rapid innovation in wireless systems and services lowering entry barrier on the market; it enables affordable mobile broadband access to all; and makes new energy efficient wireless systems possible. Secondary use of already licensed, but poorly inefficiently used spectrum, (Cognitive Radio )has been proposed as a solution to make more efficient use of the spectrum. Low spectrum occupancy in a number of measurement campaigns worldwide has been the basis for claims of large gains in spectrum efficiency by cognitive radio. However, little research has been done to substantiate these claims. The QUASAR project aims at bridging this gap between the claims made in conventional cognitive radio research and practical implementation by assessing and quantifying the real-world benefits of secondary (opportunistic) access to primary (licensed) spectrum. The analysis is based on two key features of cognitive radio: the ability of the secondary users to discover the opportunity to use the spectrum, and assessing the electromagnetic impact of secondary user transmissions on primary system (receivers). Novel approaches are taken as we go beyond the conventional notion of detecting spectrum holes into treating spectrum opportunity discovery as a data fusion problem, as well as new schemes that cope interference from multiple uncoordinated secondary users. QUASAR will provide a comprehensive analysis of the techno-economical environment and provide detailed roadmaps and guidelines on how to apply and analyze new opportunistic spectrum access business models. The project will finally provide specific and reasoned proposals to go beyond the current regulatory framework. A balanced project team will provide results of high scientific quality and strong impact on the regulatory process and wireless business.

In the last decade, carbohydrate microarrays have been core technologies for analyzing carbohydrate-mediated recognition events in a high-throughput fashion. A number of methods have been exploited for immobilizing glycans on the solid surface in a microarray format. This microarray-based technology has been widely employed for rapid analysis of the glycan binding properties of lectins and antibodies, the quantitative measurements of glycan-protein interactions, detection of cells and pathogens, identification of disease-related anti-glycan antibodies for diagnosis, and fast assessment of substrate specificities of glycosyltransferases. This review covers the construction of carbohydrate microarrays, detection methods of carbohydrate microarrays and their applications in biological and biomedical research. © 2013 The Royal Society of Chemistry.

The investigation of synthetic (abiotic) phosphate receptors seeks to provide improved methodologies for the detection, extraction, and transport of biologically, chemically, and environmentally important phosphates. The design of phosphate receptors is complicated by the acid-base properties of phosphate anions. In addition to the more common anion-hydrogen bond donor interactions, protonated phosphate anions can also interact with hydrogen bond acceptors. A variety of recognition interactions, such as hydrogen bonding, electrostatic interactions, van der Waals forces, π-surface interactions, shape complementarity, and metal coordination, have been employed alone or in concert to generate phosphate receptors. Many noncolored receptors have been functionalized with chromophores to produce covalent frameworks that undergo a pronounced color change when treated with an appropriate guest. Indicator displacement assay (IDA) is a competition method for the sensing of analytes.

Stroke | Year: 2015
Results-Among 595 patients (297 placebo and 298 tPA treated) with documented initial BT, 77.1% had initial BT <37.0°C and 22.9% 37.0°C. Patients with higher initial BT had lower baseline stroke severity in both tPA-treated patients (the National Institute of Health Stroke Scale median, 11 versus 15; P=0.05) and placebo-treated patients (median, 13 versus 16; P<0.01). Patients with higher initial BT also had lower infarction volume on computed tomography at 3 months in both tPA-treated patients (median, 9.6 versus 16.7 cm; P=0.08) and placebo-treated patients (median, 13.1 versus 28.1 cm; P=0.02), but no clinical outcome differences. Analysis of lytic treatment effect found no heterogeneity in the degree of tPA benefit in both higher and lower BT groups (37.0°C: odds ratio for the modified Rankin Scale 0-1 outcome, 2.55; 95% confidence interval, 1.05-6.21 and <37.0°C: odds ratio, 2.30; 95% confidence interval, 1.38-3.84; heterogeneity P=0.83).Conclusions-In patients with hyperacute stroke, higher presenting temperatures are associated with less severe neurological deficits and reduced final infarct volumes. Presenting temperature does not modify the benefit of tPA on 3-month favorable outcome.Background and Purpose-Body temperature (BT) is an important physiological factor in acute ischemic stroke. However, the relationship of initial BT to stroke severity and degree of benefit from thrombolytic therapy has been delineated incompletely.Methods-We analyzed the public data set of the 2 National Institute of Neurological Disorders and Stroke Tissue-Type Plasminogen Activator (tPA) stroke trials, comparing patients with lower (<37.0°C) and higher (37.0°C) presenting BT. © 2014 American Heart Association, Inc.

This paper develops a game-theoretic framework for the design and analysis of a new class of incentive schemes called intervention schemes. We formulate intervention games, propose a solution concept of intervention equilibrium, and prove its existence in a finite intervention game. We apply our framework to resource sharing scenarios in wireless communications, whose non-cooperative outcomes without intervention yield suboptimal performance. We derive analytical results and analyze illustrative examples in the cases of imperfect and perfect monitoring. In the case of imperfect monitoring, intervention schemes can improve the suboptimal performance of non-cooperative equilibrium when the intervention device has a sufficiently accurate monitoring technology, although it may not be possible to achieve the best feasible performance. In the case of perfect monitoring, the best feasible performance can be obtained with an intervention scheme when the intervention device has a sufficiently strong intervention capability. © 2012 IEEE.

Multi-antenna precoding effectively mitigates the interference in wireless networks. However, the resultant performance gains can be significantly compromised in practice if the precoder design fails to account for the inaccuracy in the channel state information (CSI) feedback. This paper addresses this issue by considering finite-rate CSI feedback from receivers to their interfering transmitters in the two-user multiple-input-multiple-output (MIMO) interference channel, called cooperative feedback, and proposing a systematic method for designing transceivers comprising linear precoders and equalizers. Specifically, each precoder/equalizer is decomposed into inner and outer components for nulling the cross-link interference and achieving array gain, respectively. The inner precoders/equalizers are further optimized to suppress the residual interference resulting from finite-rate cooperative feedback. Furthermore, the residual interference is regulated by additional scalar cooperative feedback signals that are designed to control transmission power using different criteria including fixed interference margin and maximum sum throughput. Finally, the required number of cooperative precoder feedback bits is derived for limiting the throughput loss due to precoder quantization. © 2012 IEEE.

A low sensing current non volatile flip flop includes a first stage to sense a resistance difference between two magnetic tunnel junctions (MTJs) and a second stage having circuitry to amplify the output of the first stage. The output of the first stage is initially pre-charged and determined by the resistance difference of the two MTJs when the sensing operation starts. The first stage does not have a pull-up path to a source voltage (VDD), and therefore does not have a DC path from VDD to ground during the sensing operation. A slow sense enable (SE) signal slope reduces peak sensing current in the first stage. A secondary current path reduces the sensing current duration of the first stage.

Graphene nanoribbons customized for medical use by William Sikkema, a Rice graduate student and co-lead author of the paper, are highly soluble in polyethylene glycol (PEG), a biocompatible polymer gel used in surgeries, pharmaceutical products and in other biological applications. When the biocompatible nanoribbons have their edges functionalized with PEG chains and are then further mixed with PEG, they form an electrically active network that helps the severed ends of a spinal cord reconnect. “Neurons grow nicely on graphene because it’s a conductive surface and it stimulates neuronal growth,” Tour says. In experiments at Rice and elsewhere, neurons have been observed growing along graphene. “We’re not the only lab that has demonstrated neurons growing on graphene in a petri dish,” he says. “The difference is other labs are commonly experimenting with water-soluble graphene oxide, which is far less conductive than graphene, or nonribbonized structures of graphene. “We’ve developed a way to add water-solubilizing polymer chains to the edges of our nanoribbons that preserves their conductivity while rendering them soluble, and we’re just now starting to see the potential for this in biomedical applications,” he says. He added that ribbonized graphene structures allow for much smaller amounts to be used while preserving a conductive pathway that bridges the damaged spinal cords. Tour says only 1 percent of Texas-PEG consists of nanoribbons, but that’s enough to form a conductive scaffold through which the spinal cord can reconnect. Texas-PEG succeeded in restoring function in a rodent with a severed spinal cord in a procedure performed at Konkuk University in South Korea by co-authors Bae Hwan Lee and C-Yoon Kim. Tour says the material reliably allowed motor and sensory neuronal signals to cross the gap 24 hours after complete transection of the spinal cord and almost perfect motor control recovery after two weeks. “This is a major advance over previous work with PEG alone, which gave no recovery of sensory neuronal signals over the same period of time and only 10 percent motor control over four weeks,” Tour says. The project began when Sikkema read about work by Italian neurosurgeon Sergio Canavero. Sikkema thought nanoribbons might enhance research that depended on PEG’s ability to promote the fusion of cell membranes by adding electrical conductivity and directional control for neurons as they spanned the gap between sections of the spinal cord. Contact with the doctor led to a collaboration with the South Korean researchers. Tour says Texas-PEG’s potential to help patients with spinal cord injuries is too promising to be minimized. “Our goal is to develop this as a way to address spinal cord injury. We think we’re on the right path,” he says. “This is an exciting neurophysiological analysis following complete severance of a spinal cord,” Tour says. “It is not a behavioral or locomotive study of the subsequent repair. The tangential singular locomotive analysis here is an intriguing marker, but it is not in a statistically significant set of animals. The next phases of the study will highlight the locomotive and behavioral skills with statistical relevance to assess whether these qualities follow the favorable neurophysiology that we recorded here.” Kim, co-primary author of the paper, is a research professor in the Department of Stem Cell Biology, School of Medicine, Konkuk University, Seoul, South Korea, and a researcher at Seoul National University.

Home > Press > Graphene nanoribbons show promise for healing spinal injuries: Rice University scientists develop Texas-PEG to help knit severed, damaged spinal cords Abstract: The combination of graphene nanoribbons made with a process developed at Rice University and a common polymer could someday be of critical importance to healing damaged spinal cords in people, according to Rice chemist James Tour. The Tour lab has spent a decade working with graphene nanoribbons, starting with the discovery of a chemical process to "unzip" them from multiwalled carbon nanotubes, as revealed in a Nature paper in 2009. Since then, the researchers have used them to enhance materials for the likes of deicers for airplane wings, better batteries and less-permeable containers for natural gas storage. Now their work to develop nanoribbons for medical applications has resulted in a material dubbed Texas-PEG that may help knit damaged or even severed spinal cords. A paper on the results of preliminary animal-model tests appears today in the journal Surgical Neurology International. Graphene nanoribbons customized for medical use by William Sikkema, a Rice graduate student and co-lead author of the paper, are highly soluble in polyethylene glycol (PEG), a biocompatible polymer gel used in surgeries, pharmaceutical products and in other biological applications. When the biocompatible nanoribbons have their edges functionalized with PEG chains and are then further mixed with PEG, they form an electrically active network that helps the severed ends of a spinal cord reconnect. "Neurons grow nicely on graphene because it's a conductive surface and it stimulates neuronal growth," Tour said.
