A dual, imaging and radiation system provides for finely aligned movement of a subject through the use of a computer controlled mounting stage having separate, non-gantry translational and rotational controllable movement. The system cycles a subject tissue between a treatment position where radiation doses are applied and an imaging position where high-quality computed tomography (CT) imaging is performed. Selective dose profiles and dose depths are achievable around an isocenter of the system.

Red blood cell membrane derived microparticles (RMP) are safe, economical, effective hemostatic agents in the treatment of a wide range of bleeding conditions and can, therefore, be considered as universal hemostatic agents. Effective RMP are produced from red blood cells using a high-pressure extrusion membrane shear process. The RMP can be lyophilized after production and retain activity even when stored at room temperature. RMP can be administered to original donors (autologous treatment), thus avoiding transfusion complications, or can be administered to blood type compatible recipients. RMP produced from type O, Rh negative red cells can be given to any person regardless of blood type. RMP can be administered to reduce excessive bleeding resulting from trauma, surgeries, invasive procedures and various bleeding disorders such as platelet disorders, either congenital or acquired, and coagulation disorders, either congenital or acquired. Administration of RMP prepared according to the invention demonstrates effectiveness in safely reducing bleeding.

Described here is a test strip for detection of melamine, comprising: a support configured for capillary flow of a fluid sample from a first end of the support to a second end of the support that is downstream from the first end; a conjugation pad disposed adjacent to the first end of the support and including nanoparticles configured for suspension in the sample flowing past the conjugation pad, the nanoparticles configured to produce a colorimetric effect when exposed to melamine; and a test portion downstream of the conjugation pad and including a molecular recognition agent immobilized on the support and having an affinity for melamine.

A slotted microfilter is coated with a phase changeable material having a hydrophobic state under a first temperature and a hydrophilic state under a second temperature. An example coating material is poly(N-isopropylacrylamide) (PIPAAm). The microfilter can be controlled to switch between a capture state where circulating tumor cells are captured by the microfilter and a release state, where viable tumor cells are released from capture for analysis, e.g., single cell phenotypic and genomic analysis, or for ex vivo culture growth.

The brain is constantly bombarded by stimuli, and the relative salience of these inputs determines which are more likely to capture attention. A brain system known as the 'salience network', with key nodes in the insular cortices, has a central role in the detection of behaviourally relevant stimuli and the coordination of neural resources. Emerging evidence suggests that atypical engagement of specific subdivisions of the insula within the salience network is a feature of many neuropsychiatric disorders. © 2014 Macmillan Publishers Limited.

The innate immune system is responsible for detecting microbial invasion of the cell and for stimulating host defense countermeasures. These anti-pathogen procedures include the transcriptional activation of powerful antiviral genes such as the type I interferons (IFNs) or the triggering of inflammatory responses through interleukin-1 (IL-1) production. Over the past decade, key cellular sensors responsible for triggering innate immune signaling pathways and host defense have started to be resolved and include the Toll-like receptor (TLR), RIG-I-like helicase, and the cytoplasmic nucleotide-binding oligermerization domain-like receptor families. These sensors recognize non-self pathogen-associated molecular patterns such as microbial lipopolysaccharides and nucleic acids. For example, TLR9 has evolved to detect CpG DNA commonly found in bacteria and viruses and to initiate the production of IFN and other cytokines. In contrast, AIM2 (absent in melanoma 2) has been shown to be essential for mediating inflammatory responses involving IL-1β following the sensing of microbial DNA. Recently, a molecule referred to as STING (stimulator of IFN genes) was demonstrated as being vital for recognizing cytoplasmic DNA and for activating the production of innate immune genes in response to a variety of DNA pathogens and even certain RNA viruses. Comprehending the mechanisms of intracellular DNA-mediated innate immune signaling may lead to the design of new adjuvant concepts that will facilitate vaccine development and may provide important information into the origins of autoimmune disease. © 2011 John Wiley & Sons A/S.

ConspectusThe cucurbit[n]uril (CBn) host family consists of a group of rigid macrocyclic hosts with barrel-like shapes and limited solubility in aqueous media. These hosts are capable of reaching high binding affinities with positively charged hydrophobic guests. In optimum cases, equilibrium association constant (K) values as high as 1017 M-1 have been reported, exceeding the binding affinity of the avidin-biotin host-guest pair. The synthetic CBn receptors have shattered the notion that highly stable noncovalent complexes can form only when one of the partners is a molecule of biological origin.The work described in this Account is concerned with the development of methods geared toward the reversible modulation of the binding affinity of CBn inclusion complexes under mild conditions. A good fraction of the research work has dealt with redox active guests, such as 4,4′-bipyridinium (viologen), ferrocene, and cobaltocenium derivatives. Our experimental results show that the thermodynamics and kinetics of the electron transfer reactions of these compounds can be substantially altered by complexation with CBn hosts, and therefore, electron transfer reactions can be used to exert a measure of control on the overall binding affinity of the CBn complexes. We have also developed systems in which proton transfer reactions have a strong effect on the binding affinity. With more structurally elaborate guests containing more than one adjacent binding sites, proton transfer reactions may affect the average location of the CBn host within the complexes.A series of guest compounds containing paramagnetic 2,2,6,6- tetramethylpiperidine-1-oxyl (TEMPO) residues also exhibit interesting binding properties with CB7 and CB8. The latter host forms a very stable host-guest pair with TEMPO subunits, in which the nitroxide group resides inside the host cavity. Finally, with suitable ditopic guests, we have detected distinct microscopic complexes using experimental techniques with relatively slow time scales, such as NMR spectroscopy. These unusual findings are the result of the considerable thermodynamic and kinetic stability of CBn inclusion complexes. © 2014 American Chemical Society.

Marine dissolved organic carbon (DOC) exhibits a spectrum of reactivity, from very fast turnover of the most bioavailable forms in the surface ocean to long-lived materials circulating within the ocean abyss. These disparate reactivities group DOC by fractions with distinctive functions in the cycling of carbon, ranging from support of the microbial loop to involvement in the biological pump to a hypothesized major source/sink of atmospheric CO2 driving paleoclimate variability. Here, the major fractions constituting the global ocean's recalcitrant DOC pool are quantitatively and qualitatively characterized with reference to their roles in carbon biogeochemistry. A nomenclature for the fractions is proposed based on those roles. © 2013 by Annual Reviews. All rights reserved.

The majority of currently available drugs and tool compounds exhibit an inhibitory mechanism of action and there is a relative lack of pharmaceutical agents that are capable of increasing the activity of effectors or pathways for therapeutic benefit. Indeed, the upregulation of many genes, including tumour suppressors, growth factors, transcription factors and genes that are deficient in various genetic diseases, would be desired in specific situations. Recently, key roles for regulatory long non-coding RNAs (lncRNAs) in the regulation of gene expression have begun to emerge. lncRNAs can positively or negatively regulate gene expression and chromatin architecture. Here, we review the current understanding of the mechanisms of action of lncRNAs and their roles in disease, focusing on recent work in the design of inhibitors of the natural antisense transcript (NAT) class of lncRNAs, known as antagoNAT oligonucleotides, and the issues associated with their potential therapeutic application.

STING (STimulator of INterferon Genes) has recently been identified as being essential for controlling host defense countermeasures triggered by microbial cytosolic DNA and subsequently cyclic dinucleotides (CDNs). However, chronic STING activation may also be responsible for initiating certain inflammatory diseases manifested by self DNA. Recent studies have also revealed a key role for cyclic GMP-AMP synthase (cGAS) in STING activation. Although a full understanding of the mechanisms of STING activation requires further studies, new insights into STING function afford the opportunity of designing novel compounds aimed at facilitating vaccine development or new therapies for the treatment of inflammatory disease. © 2013 Elsevier Ltd.
