This project aims to promote a widespread use of inquiry-based science teaching (IBST) in primary and secondary schools. Our major innovation is to connect IBST in school with the world of work making science more meaningful for young European students and motivating their interest in careers in S & T. To this end, we will run training courses in which pre- and in-service teachers will learn about IBST supported by teachers from vocational education, representatives from industry and informal learning. They will develop inquiry tasks in vocational contexts, leading to a large European task repository. Teachers will experience IBST themselves and through iterative cycles of implementation followed by reflection integrate this into their practice. To ensure widespread participation we will use a pyramid model in which we will work with a small number of teachers first each of which will then work with further teachers. Additionally we will develop an innovative interactive e-learning platform. To profit from the international perspective offered by the project teachers will be connected with existing European networks and our own thematic network on IBST through (virtual) meetings, a forum and the task repository. We will adopt a systemic approach to dissemination working with teachers and additionally parents, students, school authorities and policy makers. National and European advisory panels will bring together stakeholders to advise partners throughout the project; dialogue with policy makers will be facilitated by workshops and policy papers. To ensure effectiveness our work will be informed by a detailed analysis of the educational systems in partner nations. We plan to reach more than 65.000 teachers directly and 800.000 teachers indirectly (via stakeholders, media). Throughout, our work will be subject to rigorous evaluation and measures of quality assurance that will be both summative and formative in informing the progress of the project.

Background. Cholinesterases are a group of serine hydrolases that split the neurotransmitter acetylcholine (ACh) and terminate its action. Of the two types, butyrylcholinesterase and acetylcholinesterase (AChE), AChE plays the key role in ending cholinergic neurotransmission. Cholinesterase inhibitors are substances, either natural or man-made that interfere with the break-down of ACh and prolong its action. Hence their relevance to toxicology and pharmacology. Methods and Results. The present review summarizes current knowledge of the cholinesterases and their inhibition. Particular attention is paid to the toxicology and pharmacology of cholinesterase-related inhibitors such as nerve agents (e.g. sarin, soman, tabun, VX), pesticides (e.g. paraoxon, parathion, malathion, malaoxon, carbofuran), selected plants and fungal secondary metabolites (e.g. aflatoxins), drugs for Alzheimer's disease (e.g. huperzine, metrifonate, tacrine, donepezil) and Myasthenia gravis (e.g. pyridostigmine) treatment and other compounds (propidium, ethidium, decamethonium). Conclusions. The crucial role of the cholinesterases in neural transmission makes them a primary target of a large number of cholinesterase-inhibiting drugs and toxins. In pharmacology, this has relevance to the treatment of neurodegenerative disorders. © M. Pohanka.

Alzheimer's disease (AD) is a neurodegenerative disorder with no known cure and rapid rise in incidence. The predominant cognitive impairment is currently treated using cognitive enhancers like cholinesterase inhibitors. The two molecular hallmarks of AD are amyloid plaques created from an amyloid precursor protein and hyperphosphorylated tau protein that is deposited as neurofibrillary tangles inside neurons. A number of pathological mechanisms follow or precede these formations. Alteration in mitochondrial function and deposition of heavy metals are reported. The disease progression is enhanced by oxidative stress. However, the role of oxidative stress is not universally accepted. The current review covers and discusses the basic evidence and role of oxidative stress in AD development. © 2014 Bentham Science Publishers.

Summary Age related neurodegenerative disorders are becoming a serious public health problem. Alzheimer's disease (AD) is a progressive disease pathologically recognizable by deposition of neurofibrillary tangles and amyloid plaques. Oxidative stress probably plays a pivotal role in AD, but despite expectations, antioxidants such as vitamin E, vitamin C, β carotene, and flavonoids have failed as effective prophylaxis and/or treatment. Melatonin, a hormone controlling circadian rhythm, is a potent terminal antioxidant. In vitro tests and animal models have established that the application of melatonin could be beneficial for the amelioration of AD progression. Unfortunately, melatonin effects in human beings are not well understood and a lot of work has still to be done. The review summarizes the basic facts about melatonin and its prospects as a treatment for AD using its hormonal and antioxidant properties. © Journal of Applied Biomedicine.

It is explained how to find the de Rham decomposition of a Riemannian manifold and the Wu decomposition of a Lorentzian manifold. For that it is enough to find parallel symmetric bilinear forms on the manifold, and do some linear algebra. This result will allow to compute the connected holonomy group of an arbitrary Riemannian or Lorentzian manifold. © 2014 IOP Publishing Ltd.

Summary: The aim of this study was to assess the relationships between both a marker of bone formation and a marker of bone turnover and age, sex, and pubertal stage in a group (n =439) of healthy children and adolescents. These reference data should be instrumental in interpretation of results. Introduction: The skeletal system has high metabolic activity. In children, bone markers may be useful in diagnostics and treatment management of skeletal diseases but there could be difficulties with interpretation of results. Compared with adults, children have elevated bone marker levels due to high skeletal growth velocity and rapid bone turnover. Thus, valid age- and sex-specific reference data should be obtained for each pediatric population living in a particular climate and with a similar lifestyle. The aim of this study was to assess the relationships between both a marker of bone formation (procollagen type I N-terminal propeptide [PINP]) and a marker of bone turnover (osteocalcin [OC]) and age, sex, and pubertal stage in a group of healthy children and adolescents. Methods: Four hundred thirty-nine healthy Caucasian children participated. Their height, weight, and pubertal stage were recorded. Fasting PINP and OC weremeasured using a morning blood sample. Results: The highest levels of PINP were observed during the first year of life. There is no OC postnatal peak, but levels are higher than the adult reference interval throughout childhood. OC peaks with the pubertal growth spurt at second-third Tanner stage of breast development in girls and at second-third Tanner stage of genital development in boys. PINP peaks during second-third Tanner stage of breast development in girls and at third Tanner stage of genital development in boys. Conclusion: This study provides reference data for OC and PINP in healthy Caucasian children from a Central European population. © International Osteoporosis Foundation and National Osteoporosis Foundation 2013.

Acetylcholinesterase and butyrylcholinesterase are the only two known cholinesterases. Acetylcholinesterase plays an important part in cholinergic system. It terminates neurotransmission by hydrolysis of transmitter acetylcholine. The role of butyrylcholinesterase is not well understood. It is able to detoxify several compounds such as cocaine, succinylcholine, and so forth. The current review is focused on the application of cholinesterases in biorecognition. Cholinesterases are important markers in the body. Butyrylcholinesterase activity in plasma can serve as a liver function test or specific marker for sensitivity to myorelaxants or liver carcinoma. Both cholinesterases can serve as markers of poisoning by some neurotoxic compounds. Nerve agents (sarin, soman, tabun, VX), some Alzheimer disease drugs (galantamine, huperzine, donepezil, rivastigmine), pesticides (carbofuran, trichlorfon, paraoxon, malaoxon), and natural toxins (aflatoxin, pyridostigmine) can act as inhibitors of butyrylcholinesterase and/or acetylcholinesterase. Devices filled with immobilized cholinesterases can be used for the assay of the aforementioned toxins. In this review, methods for examination of cholinesterases activity in the body and in analytical devices are described. Applications, types of diagnosis, and assays are described as well. © 2013 Copyright Taylor and Francis Group, LLC.

Introduction: Management of refractory chronic lymphocytic leukemia (CLL) represents a major challenge because of the poor prognosis and limited treatment options. While corticosteroids have been used to treat CLL since 1940s, their benefit has never been conclusively proved. Recently, several groups reported use of high-dose corticosteroids (methylprednisolone or dexamethasone) either alone or combined with chemotherapy and/or monoclonal antibodies in relapsed/refractory CLL. Areas covered: While efficacy of high-dose corticosteroids is excellent including responses in patients with bulky lymphadenopathy or those considered ultra high-risk CLL because of deletion and/or mutation of p53 gene, the duration of response is still unsatisfactory. Combination with monoclonal antibodies seems to improve therapeutic efficacy but no randomized trials have been conducted. For the purpose of this review, a search for terms, high-dose corticosteroids/methylprednisolone/dexamethasone, and chronic lymphocytic leukemia has been performed in PubMed and database of abstracts from American Society of Hematology Meetings. Expert opinion: High-dose corticosteroids appear to play an important role in the management of highly pretreated relapsed/refractory CLL including patients with massive lymphadenopathy. Myelosuppression is usually limited but infectious toxicity, including increased risk of invasive fungal infections, represents the most dreaded side effects. This therapeutic approach should be further tested within large prospective trials, to optimize efficacy and safety. © 2012 Informa UK, Ltd.

Alpha7 nicotinic acetylcholine receptor (α7 nAChR) is an important part of the cholinergic nerve system in the brain. Moreover, it is associated with a cholinergic anti-inflammatory pathway in the termination of the parasympathetic nervous system. Antagonists of α7 nAChR are a wide group represented by conotoxin and bungarotoxin. Even Alzheimer's disease drug memantine acting as an antagonist in its side pathway belongs in this group. Agonists of α7 nAChR are suitable for treatment of multiple cognitive dysfunctions such as Alzheimer's disease or schizophrenia. Inflammation or even sepsis can be ameliorated by the agonistic acting compounds. Preparations RG3487, SEN34625/WYE-103914, SEN12333, ABT-107, Clozapine, GTS-21, CNI-1493, and AR-R17779 are representative examples of the novel compounds with affinity toward the α7 nAChR. Pharmacological, toxicological, and medicinal significance of α7 nAChR are discussed throughout this paper. © 2012 by the authors; licensee MDPI, Basel, Switzerland.
