Skin aging is accelerated by multiple extrinsic factors: ultraviolet radiation, smoking and pollution increase oxidative activity, damaging cellular and extracellular components such as DNA, proteins, and lipids. With age, collagen and hyaluronic acid levels decline, resulting in loss of elasticity and moisture of the skin. Over time this damage leads to characteristic signs that make the skin look older: altered facial contour, sagging skin, wrinkles, and an uneven complexion. This study evaluated the anti-aging effects of a new facial cream formulated with carnosine, Alteromonas ferment extract, crosspolymer hyaluronic acid, and a tripeptide. An open-label intra-individual study to assess the anti-aging efficacy of the investigational product in 33 women aged 45 to 65 years. The product was applied twice daily for 56 days. Facial contour and skin deformation, elasticity, hydration, and complexion were measured with specialized equipment at baseline and days 28 and 56. Additionally, subjects completed questionnaires at days 28 and 56 on the perceived efficacy and cosmetic characteristics of the product. After 56 days of use of the investigational product, a redefining effect was observed, with a significant decrease in sagging jawline (7%). Skin was significantly more hydrated (12%), firmer (29%), and more elastic (20%) ( P <0.001 for all). On complexion assessment, skin texture (a measure of skin smoothness) and spots (brown and red skin lesions) also improved significantly (12% and 6% decrease, respectively). In the subjective self-evaluation, the majority of subjects reported that the skin was visibly tightened and more elastic, flexible, and moisturized (91%, 88%, 91%, and 90%, respectively). The product was well tolerated with no adverse events reported during the study. This new cosmetic product demonstrated anti-aging effects after 56 days of use, most notably a redefined facial contour and improved complexion. It is a safe and effective anti-aging product.

Based on the critical approach in health communication, along with Habermas's theory of legitimation and Ellul's theory of propaganda, this qualitative study analyzes the political and ideological dimensions of the video advertisements used in the 2012 anti-smoking and 2014 anti-drinking campaigns in the Republic of Moldova. This analysis shows that these health videos support male domination and exclusion of the poor and legitimate the current political leadership with its declared pro-European orientation. This study uniquely contributes to the critical approach in health communication by focusing on the post-Soviet context in which statehood and national identity are unstable and societies are torn between the Russian and (post-)Soviet influences on one hand and European aspirations on the other. Drawing on critical scholarship in global health communication, this article calls for greater respect and recognition of Moldova's local culture and definition of health.

2017-01-01

Anti-vibration gloves have been used in real workplaces to reduce vibration transmitted through hand-held power tools to the hand. Generally materials used for vibration attenuation in gloves are resilient materials composed of certain synthetic and/or composite polymers. The mechanical characteristics of the resilient materials used in anti-vibration gloves are prone to be influenced by environmental conditions such as temperature, humidity, and photo-irradiation, which cause material degradation and aging. This study focused on the influence of shelf aging on the vibration attenuation performance of air-packaged anti-vibration gloves following 2 yr of shelf aging. Effects of shelf aging on the vibration attenuation performance of anti-vibration gloves were examined according to the Japan industrial standard JIS T8114 test protocol. The findings indicate that shelf aging induces the reduction of vibration attenuation performance in air-packaged anti-vibration gloves. PMID:28978817

Counterfeit medicines are a global public health risk. We assess counterfeit reports involving the legitimate supply chain using 2009–2011 data from the Pharmaceutical Security Institute Counterfeit Incident System (PSI CIS) database that uses both open and nonpublic data sources. Of the 1,510 identified CIS reports involving counterfeits, 27.6% reported China as the source country of the incident/detection. Further, 51.3% were reported as counterfeit but the specific counterfeit subcategory was not known or verifiable. The most prevalent therapeutic category was anti-infectives (21.1%) with most reports originating from health-related government agencies. Geographically, Asian and Latin American regions and, economically, middle-income markets were most represented. A total of 127 (64.8%) of a total of 196 countries had no legitimate supply chain CIS counterfeit reports. Improvements in surveillance, including detection of security breaches, data collection, analysis, and dissemination are urgently needed to address public health needs to combat the global counterfeit medicines trade.

The Legitimation of Self-Regulation and Co-Regulation in Corporatist Concepts of Legal Scholars in the Weimar Republic

Directory of Open Access Journals (Sweden)

Peter Collin

2017-03-01

Full Text Available Corporatist regulation has a hybrid structure in that it covers state regulation, regulated self-regulation as well as private-public co-regulation. Notably diverging from the standard mode of state regulation, such arrangements required a higher degree of legitimation. Corporatist concepts flourished in the Weimar Republic. This paper deals with three legal scholars’ considerations regarding how to legitimize corporatist models, namely Edgar Tatarin-Tarnheyden, Heinrich Herrfahrdt, and Friedrich Glum. Their institutional touchstone was the Imperial Economic Council, as provided for by article 165 of the Weimar Constitution. This article envisioned a multi-level system of economic councils ranging from regional economic councils up to the Imperial Economic Council and involving representatives of all occupational groups in the performance of state tasks. However, only a Provisional Imperial Economic Council, with a restricted consultative remit, was ever actually established. Based on this model, Tatarin-Tarnheyden, Heinrich Herrfahrdt, and Friedrich Glum conceptualized organizational structures aiming at the comprehensive inclusion of non-state actors. They were legitimized primarily with reference to their output; that is, these organizational forms were supposed to enable a more appropriate and efficient realization of public interests. The input-based argument was basically a question of participation, which implies considerable proximity to typical topoi of democratic legitimation. This similarity is perhaps counter-intuitive, given that corporatist concepts are traditionally associated with anti-democratic ideologies due to their anti-parliamentarian slant. The numerous points of convergence between corporatist and democratic thought simultaneously reflect the heterogeneity of democratic reasoning in the Weimar period and the openness for ideas that were sceptical of—or even hostile to—parliamentary democracy and the party

Full Text Available Scholars employing world-system theory have tended to examine how world-systemsdevelop and expand, while few have addressed the fragmentation or collapse of world-systems. This paper explores the conditions of world-system collapse using Habermas's concept of legitimation crisis as a starting point. The paper posits that legitimation crises are a recurring problem in world-systems and have led to collapse in a number of cases. Prehistoric North American and Pacific world-systems are used as examples.

With the aim of improving the anti-aging properties of nitrile-butadiene rubber (NBR), a functional organic filler, namely LDH⁻SAS, prepared by intercalating 4-amino-benzenesulfonic acid monosodium salt (SAS) into layered double hydroxides (LDHs) through anion exchange, was added to nitrile-butadiene rubber (NBR), giving the NBR/LDH⁻SAS composites. Successful preparation of LDH⁻SAS was confirmed by XRD, TGA and FTIR. LDH⁻SAS was well dispersed in the NBR matrix, owing to its strong interaction with the nitrile group of NBR. The obtained NBR/LDH⁻SAS composites exhibited excellent thermo-oxidative aging resistance as shown by TGA-DSC. Further investigation by ATR-FTIR indicated that SAS can capture the radical groups, even during the aging process, which largely accounts for the improved aging resistance.

Scientific achievements in the last few decades, leading to effective therapeutic interventions, have dramatically improved human life expectancy. Consequently, aging has become a significant problem and represents the major risk factor for most human pathologies including diabetes, cardiovascular diseases, neurological disorders, and cancer. Scientific discoveries over the past two decades have been instrumental in dissecting molecular mechanism(s) which play important roles in determining longevity. The same understanding has also led to the acknowledgement of the plurality of 'causes' which act either alone or in combination to create the condition which can be defined as 'aging'. Areas covered: Over the years, several concepts have been put forward for the development of a viable anti-aging regimen. In this review, the authors extensively review anti aging interventions based on caloric restriction, activation of telomerase, autophagy inducers, senolytic therapeutics, plasma membrane redox system (PMRS) activators, epigenetic modulators, and stem cell therapies. Expert opinion: Based upon our current understanding, one of the most promising approaches for a successful anti-aging strategy includes the activation of adenosine monophosphate dependent protein kinase (AMPK). Another strategy may involve activation of PMRS. Future research efforts are likely to focus on nutrient and energy sensing molecular pathways which include mTOR, IGF-1, AMPK and the sirtuins.

Retinoic acid has been shown to improve the aged-appearing skin. However, less is known about the anti-ageing effects of retinol (ROL, vitamin A), a precursor of retinoic acid, in aged human skin in vivo. This study aimed to investigate the molecular basis of ROL anti-ageing properties in naturally aged human skin in vivo. Sun-protected buttock skin (76 ± 6 years old, n = 12) was topically treated with 0.4% ROL and its vehicle for 7 days. The effects of topical ROL on skin epidermis and dermis were evaluated by immunohistochemistry, in situ hybridization, Northern analysis, real-time RT-PCR and Western analysis. Collagen fibrils nanoscale structure and surface topology were analysed by atomic force microscopy. Topical ROL shows remarkable anti-ageing effects through three major types of skin cells: epidermal keratinocytes, dermal endothelial cells and fibroblasts. Topical ROL significantly increased epidermal thickness by stimulating keratinocytes proliferation and upregulation of c-Jun transcription factor. In addition to epidermal changes, topical ROL significantly improved dermal extracellular matrix (ECM) microenvironment; increasing dermal vascularity by stimulating endothelial cells proliferation and ECM production (type I collagen, fibronectin and elastin) by activating dermal fibroblasts. Topical ROL also stimulates TGF-β/CTGF pathway, the major regulator of ECM homeostasis, and thus enriched the deposition of ECM in aged human skin in vivo. 0.4% topical ROL achieved similar results as seen with topical retinoic acid, the biologically active form of ROL, without causing noticeable signs of retinoid side effects. 0.4% topical ROL shows remarkable anti-ageing effects through improvement of the homeostasis of epidermis and dermis by stimulating the proliferation of keratinocytes and endothelial cells, and activating dermal fibroblasts. These data provide evidence that 0.4% topical ROL is a promising and safe treatment to improve the naturally aged human skin

Authors argue that the effectiveness of the mechanism of legal regulation largely depends on the proper use of legal permissions. Particular attention is paid to such kind of legal mean as a legitimate interest. The article draws attention to the fact that if a legal right or freedom are such kind of permissions which are guaranteed by the law in order to sustain certain demands of subjects of law, the legitimate interest is qualitatively different mean of regulation. The authors suggest considering a legitimate interest as reflected in the objective law legal possibility of subjects of law to enjoy certain social benefits and to seek protection from the state authorities in order to meet their interests which are not contradictory to provisions of law. Qualitative difference between legitimate interest and legal right and freedom is that the legitimate interest is an opportunity, guaranteed to a lesser extent than the permitted behavior within a legal right or freedom. Legitimate interest is a mere permission, admitted by the state and to some extent supported by it. But legal right and freedom - are those means of regulation, which are directly approved and sanctioned by the state which presuppose duty of a person to a particular behavior.

Recently, we reported on the anti-ageing effects of K6PC-5. This compound induced keratinocyte differentiation and fibroblast proliferation by increasing sphingosine-1 phosphate synthesis. We performed this study to confirm the anti-ageing effects of new synthetic products (the K6EAA series) derived from K6PC-5 through an amino group induction. Cellular responses such as differentiation, proliferation and calcium mobilization were investigated using cultured human keratinocytes and fibroblasts. Also, we measured the expressions of collagen mRNA and protein using real time RT-PCR and ELISA, respectively. The K6EAA-L12 product, selected by in vitro screening, was evaluated for anti-ageing effects on intrinsically and extrinsically (photo) aged models of hairless mice. In the intrinsically aged murine skin, K6EAA-L12 showed anti-ageing effects by activating collagen synthesis, eventually causing dermal thickening. Also, in the photo-aged skin, the dermal collagen density and dermal thickness were increased. In photo-aged murine skin, K6EAA-L12 increased stratum corneum integrity by increasing corneodesmosome density and improved the barrier recovery rate. However, there were no changes in the expressions of epidermal differentiation maker proteins. In conclusion, topical K6EAA-L12, a new synthetic K6PC-5 derivative, improves intrinsically and extrinsically (photo) aged skin by increasing the collagen density and improving the skin barrier function. © 2011 John Wiley & Sons A/S.

Dampness evil is the source of all diseases, which is easy to cause disease and promote aging, while aging could also promote the occurence and development of diseases. In this paper, the relationship between the dampness evil and aging would be discussed, to find the anti-aging active ingredients in traditional Chinese medicine (TCM), and analyze the anti-aging mechanism of dampness eliminating drug. Molecular docking technology was used, with aging-related mammalian target of rapamycin as the docking receptors, and chemical components of Fuling, Sangzhi, Mugua, Yiyiren and Houpo as the docking molecules, to preliminarily screen the anti-aging active ingredients in dampness eliminating drug. Through the comparison with active drugs already on the market (temsirolimus and everolimus), 12 kinds of potential anti-aging active ingredients were found, but their drug gability still needs further study. The docking results showed that various components in the dampness eliminating drug can play anti-aging activities by acting on mammalian target of rapamycin. This result provides a new thought and direction for the method of delaying aging by eliminating dampness. Copyright© by the Chinese Pharmaceutical Association.

Effect of Graphene Oxide on Anti-aging Property of Nitrile Butadiene Rubber

Full Text Available The blends with higher damping performance was prepared based on nitrile butadiene rubber(NBR with addition of graphene oxide(GO and modified graphene oxide(MGO prepared by improved Hammer method. Meanwhile, the damping property and the anti-aging property of the blends were investigated by DMA, AFM, SEM and so forth. The results show that after the addition of the GO and MGO, the tangent of loss angle(tanδ increases and also the anti-aging property is improved. When adding less amount of GO in the matrix, the anti-aging property is better; when adding MGO in the matrix, the amount of addition is not obviously related with the anti-aging property of the blends. The dispersion of GO and MGO has positive correlation with its anti-aging property. By microscopic analysis, the main reason for the decrease of anti-aging property of the blends is the agglomeration of the GO. The interface effect formed by the addition of MGO and GO is the main reason for its high damping property and anti-aging property.

With many effective anti-aging solutions for the face, consumer focus is now turning to other parts of the body including the delicate skin on the neck. This study investigates the effect of a new neck cream on the appearance of texture, fine lines and wrinkles, laxity, and hydration. 85 adult females ages 35-65 with Fitzpatrick skin types I through IV applied the test neck cream twice daily for a 3-month study period. Screening was conducted at Baseline, 2, 30, 60, and 90 days via a virtual trial. Subjects rated satisfaction in each of 4 anti-aging categories including hydration, texture, appearance of wrinkles, and appearance of laxity as well as three product attributes including application, feel, and smell. Improvement was statistically significant for all measured categories (hydration, texture, appearance of wrinkles, and appearance of laxity) with 94% of study subjects noting improvement in one or more of the measured categories. Further, the quantity of "Satisfied" and "Highly Satisfied" assessments increased 8-fold from baseline with a 94x increase in the quantity of "Highly Satisfied" assessments. The results demonstrate the product's rapid and continuing ability to improve the self-perceived signs of aging in the neck area including improvement in skin texture on the neck and a reduction in the appearance of wrinkles and laxity along the jawline. Future studies are recommended to determine the primary action mechanisms and to assess the degree of improvement by blinded physician assessment.

This intracellular protein kinase complex plays a key role in stimulating anabolic and cell growth promoting processes, while inhibiting autophagy. On the other hand, downregulation results in antiproliferative, anticancer and intensive cell-repairing effects leading to life and health span extension and stress resistance. The mTOR complex regulates such basic cell activities and integrates signals from nutrition sensing, energy metabolism, insulin and growth factors, stress and hypoxia.brImportantly, mTOR can be inhibited by some molecules and their analogs (rapamycin, resveratrol, metformin, e.g., which are released naturally from plants, yeast or bacteria to protect against natural enemies. Its dosage resembles an adaptive hormetic response relationship, as high concentrations are toxic and mild doses are associated with anticancer and antiaging effects. This opens up new avenues for their use as „anti-aging pills“ in humans.brRecent human data suggest that metformin, rapamycin and other mTOR-inhibitors could delay heart disease, cancer, cognitive decline and improve survival time in people with diabetes mellitus. In addition, response to influenca vaccine was enhanced by rapamycin in adults with immunosenescence, indicating beneficial anti-aging effects in the elderly.br“Treat aging” is an actual call to recognize aging as an indication appropriate for clinical trials and treatments, as it was recently approved by the Federal Drug Administration (FDA USA. p bKurzfassung/b: Die ansteigende Morbidität und Invalidität in alternden Industrienationen stößt an die Grenzen der Ressourcen

Biosystems Study of the Molecular Networks Underlying Hippocampal Aging Progression and Anti-aging Treatment in Mice

Directory of Open Access Journals (Sweden)

Jiao Wang

Full Text Available Aging progression is a process that an individual encounters as they become older, and usually results from a series of normal physiological changes over time. The hippocampus, which contributes to the loss of spatial and episodic memory and learning in older people, is closely related to the detrimental effects of aging at the morphological and molecular levels. However, age-related genetic changes in hippocampal molecular mechanisms are not yet well-established. To provide additional insight into the aging process, differentially-expressed genes of 3- versus 24- and 29-month old mice were re-analyzed. The results revealed that a large number of immune and inflammatory response-related genes were up-regulated in the aged hippocampus, and membrane receptor-associated genes were down-regulated. The down-regulation of transmembrane receptors may indicate the weaker perception of environmental exposure in older people, since many transmembrane proteins participate in signal transduction. In addition, molecular interaction analysis of the up-regulated immune genes indicated that the hub gene, Ywhae, may play essential roles in immune and inflammatory responses during aging progression, as well as during hippocampal development. Our biological experiments confirmed the conserved roles of Ywhae and its partners between human and mouse. Furthermore, comparison of microarray data between advanced-age mice treated with human umbilical cord blood plasma protein and the phosphate-buffered saline control showed that the genes that contribute to the revitalization of advanced-age mice are different from the genes induced by aging. These results implied that the revitalization of advanced-age mice is not a simple reverse process of normal aging progression. Our data assigned novel roles of genes during aging progression and provided further theoretic evidence for future studies exploring the underlying mechanisms of aging and anti-aging-related disease

This is especially the case if the threat seems to be illegitimate in nature. However, reactance theory suggests that reactance should also be aroused when people are exposed to legitimate freedom threats. In this article we first aim to show that both illegitimate and legitimate freedom threats evoke reactance. Second, we aim to extend past work on reactance by exploring the underlying process of experiencing a legitimate versus an illegitimate restriction. In the current study (N = 57 participants were restricted in an illegitimate (unexpected and inappropriate or legitimate (unexpected but appropriate way, or were not restricted at all. We assessed participants’ experience of reactance, their behavioral intentions to restore their freedom, their approach motivational states, as well as their physiological arousal (heart rate. Results indicated that when restricted in an illegitimate or a legitimate way, participants indicated the same amount of reactance as well as anger. However, when looking at people’s physiological reactions, important differences between illegitimate and legitimate restrictions become apparent. Illegitimate restrictions led to an immediate arousal, whereas legitimate restrictions led to a time delayed arousal. This suggests that illegitimate restrictions lead to a sudden increase in aversive arousal. Legitimate restrictions, however, seem to be associated with a more cognitive process in which people first need to structure their thoughts and reflect upon the situation before getting into the feeling of reactance in a physiologically arousing sense. Moreover a mediation analysis could show that behavioral intentions to regain one’s freedom result in positive and negative approach motivation. In sum

The Meaning of Anti-Americanism: A Performative Approach to Anti-American Prejudice

Directory of Open Access Journals (Sweden)

Felix Knappertsbusch

2013-06-01

Full Text Available A contribution to the ongoing debate on how anti-Americanism can be adequately conceptualized and how such prejudice can be distinguished from legitimate criticism, arguing that part of these conceptual problems arise from a too narrow focus on defining anti-Americanism and the use of standardized empirical operationalizations. Such approaches exhibit severe limitations in grasping the flexibility of the phenomenon in everyday discourse and often underestimate or ignore the interpretive aspect involved in identifying utterances as anti-American prejudice. Alternatively, a performative approach is proposed, understanding anti-Americanism as a network of speech acts bound by family resemblance rather than identical features. In combination with qualitative empirical research methods such a conceptualization is especially suited to account for the flexible, situated use of anti-American utterances. At the same time it grants reflexivity to the research concept, in the sense of a close description of the scientific application of the notion of anti-Americanism. Two empirical examples from an interview study on anti-American speech in Germany illustrate the potential of such an approach, providing an insight into how anti-Americanism is incorporated into the construction and expression of racist and revisionist national identifications in everyday discourse.

Mechanisms Underlying the Anti-Aging and Anti-Tumor Effects of Lithocholic Bile Acid

Directory of Open Access Journals (Sweden)

Anthony Arlia-Ciommo

2014-09-01

Full Text Available Bile acids are cholesterol-derived bioactive lipids that play essential roles in the maintenance of a heathy lifespan. These amphipathic molecules with detergent-like properties display numerous beneficial effects on various longevity- and healthspan-promoting processes in evolutionarily distant organisms. Recent studies revealed that lithocholic bile acid not only causes a considerable lifespan extension in yeast, but also exhibits a substantial cytotoxic effect in cultured cancer cells derived from different tissues and organisms. The molecular and cellular mechanisms underlying the robust anti-aging and anti-tumor effects of lithocholic acid have emerged. This review summarizes the current knowledge of these mechanisms, outlines the most important unanswered questions and suggests directions for future research.

'Healthy Ageing' policies and anti-ageing ideologies and practices: on the exercise of responsibility.

Science.gov (United States)

Cardona, Beatriz

2008-12-01

This paper explores how the exercise of the ethics of 'responsibility' for health care advanced through 'healthy ageing' and 'successful ageing' narratives in Western countries animates an array of 'authorities', including the 'anti-ageing medicine' movement as a strategy to address the anxieties of growing old in Western societies and as a tool to exercise the ethos of 'responsibility'. The choice of this type of authority as a source of guidance for self-constitution and the exercise of the 'responsible self', this paper will argue, enables the enactment of a type of late modernity notion of citizenship for ageing individuals based on principles of agelessness, health, independence and consumption power. Through interviews with anti-ageing consumers, however, it is also possible to argue the existence of tensions and contradictions that such a rigid model of self-constitution in later life produces, and the potential forms of resistance and contestations that may emerge as a result. In this way the current 'war on anti-ageing medicine' (Vincent 2003) becomes also symptomatic of bigger 'wars' taking place not only between institutions competing for control over knowledge and management of ageing, but between those in favour and against the homogenisation of life under the language of universal science, reason and market rationality.

Caucasian facial L* shifts may communicate anti-ageing efficacy.

Zedayko, T; Azriel, M; Kollias, N

2011-10-01

An ageing study was conducted to capture skin colour parameters in the CIELab system from Caucasians of both genders and all available adult ages. This study produced a linear correlation between L* and age for a Caucasian population between 20 and 59 years of age as follows: (L* value) = -0.13 × (Age in years) + 63.01. Previous studies have addressed age-related changes in skin colour. This work presents a novel consumer correlated quantitative linear model of skin brightness by which to communicate age-related changes. Two product assessment studies are also presented here, demonstrating the ability of anti-ageing products to deliver on objective and subjective improvements in skin brightness. It was determined to be possible to use the fundamental Caucasian L*-age correlation to describe product benefits in a novel quantitative and consumer-relevant fashion, through the depiction of a 'years back' calculation. © 2011 Johnson & Johnson Consumer Products Company.

Age-related conditions are the leading causes of death and health-care costs. Reducing the rate of aging would have enormous medical and financial benefits. Myriad genes and pathways are known to regulate aging in model organisms, fostering a new crop of anti-aging companies. Approaches range from drug discovery efforts to big-data methods and direct-to-consumer (DTC) strategies. Challenges and pitfalls of commercialization include reliance on findings from short-lived model organisms, poor biological understanding of aging, and hurdles in performing clinical trials for aging. A large number of potential aging-associated interventions and targets exist, but given the long validation times only a small fraction can be explored for clinical applications. If even one company succeeds, however, the impact will be huge. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

Emerging Roles of Ganoderma Lucidum in Anti-Aging

Wang, Jue; Cao, Bin; Zhao, Haiping; Feng, Juan

2017-01-01

Ganoderma lucidum is a white-rot fungus that has been viewed as a traditional Chinese tonic for promoting health and longevity. It has been revealed that several extractions from Ganoderma lucidum, such as Ethanol extract, aqueous extract, mycelia extract, water soluble extract of the culture medium of Ganoderma lucidum mycelia, Ganodermasides A, B, C, D, and some bioactive components of Ganoderma lucidum, including Reishi Polysaccharide Fraction 3, Ganoderma lucidum polysaccharides I, II, III, IV, Ganoderma lucidum peptide, Ganoderma polysaccharide peptide, total G. lucidum triterpenes and Ganoderic acid C1 could exert lifespan elongation or related activities. Although the use of Ganoderma lucidum as an elixir has been around for thousands of years, studies revealing its effect of lifespan extension are only the tip of the iceberg. Besides which, the kinds of extractions or components being comfrimed to be anti-aging are too few compared with the large amounts of Ganoderma lucidum extractions or constituients being discovered. This review aims to lay the ground for fully elucidating the potential mechanisms of Ganoderma lucidum underlying anti-aging effect and its clinical application. PMID:29344411

2017-07-01

Cooperation in social systems such as tax honesty is of central importance in our modern societies. However, we know little about cognitive and neural processes driving decisions to evade or pay taxes. This study focuses on the impact of perceived tax authority and examines the mental chronometry mirrored in ERP data allowing a deeper understanding about why humans cooperate in tax systems. We experimentally manipulated coercive and legitimate authority and studied its impact on cooperation and underlying cognitive (experiment 1, 2) and neuronal (experiment 2) processes. Experiment 1 showed that in a condition of coercive authority, tax payments are lower, decisions are faster and participants report more rational reasoning and enforced compliance, however, less voluntary cooperation than in a condition of legitimate authority. Experiment 2 confirmed most results, but did not find a difference in payments or self-reported rational reasoning. Moreover, legitimate authority led to heightened cognitive control (expressed by increased MFN amplitudes) and disrupted attention processing (expressed by decreased P300 amplitudes) compared to coercive authority. To conclude, the neuronal data surprisingly revealed that legitimate authority may led to higher decision conflict and thus to higher cognitive demands in tax decisions than coercive authority. © The Author (2017).

To determine changes in anti-retinal antibodies (ARAs) during anti-VEGF therapy in patients with exudative age-related macular degeneration (AMD) and to assess the correlations between ARAs and disease activity. The study comprised 98 patients treated with intravitreal bevacizumab. The ophthalmic examination included best corrected visual acuity (BCVA), slit lamp biomicroscopy, fundoscopy, fluorescein angiography (FA), and optical coherence tomography (OCT). Serum ARAs levels were assessed by indirect immunofluorescence (IIF) on normal monkey retina substrate. These studies were repeated at 4 week intervals within 8 months of a follow-up. The sera of 50 sex- and age-matched healthy subjects were used as controls. At baseline examination, 94 (95.5%) of the 98 patients were positive for ARAs. The ARAs titres were significantly higher (p = 0.0000) than in controls. A positive correlation was found between titres of ARAs and the diameter of choroidal neovascularization (CNV) as measured by FA (p = 0.0000), and central retinal thickness (CRT) assessed by OCT (p = 0.0000). A positive correlation was also found between the diameter of CNV, CRT and the complexity of circulating ARAs. Following treatment all patients demonstrated significant decrease in ARAs levels as well as improvement of BCVA, reduction of subretinal fluid on OCT and decreased leakage on FA. Changes in serum ARAs levels occurred in parallel with clinical outcomes of anti-VEGF therapy. Treatment reduced serum levels of ARAs, with the greatest reduction occurring during the 'loading' phase. This study demonstrated that ARAs may act as a serum biomarker of the efficacy of anti-VEGF therapy. © 2014 Acta Ophthalmologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

Drosophila melanogaster as a model system for the evaluation of anti-aging compounds.

Science.gov (United States)

Jafari, Mahtab

2010-01-01

Understanding the causes of aging is a complex problem due to the multiple factors that influence aging, which include genetics, environment, metabolism and reproduction, among others. These multiple factors create logistical difficulties in the evaluation of anti-aging agents. There is a need for good model systems to evaluate potential anti-aging compounds. The model systems used should represent the complexities of aging in humans, so that the findings may be extrapolated to human studies, but they should also present an opportunity to minimize the variables so that the experimental results can be accurately interpreted. In addition to positively affecting lifespan, the impact of the compound on the physiologic confounders of aging, including fecundity and the health span--the period of life where an organism is generally healthy and free from serious or chronic illness--of the model organism needs to be evaluated. Fecundity is considered a major confounder of aging in fruit flies. It is well established that female flies that are exposed to toxic substances typically reduce their dietary intake and their reproductive output and display an artifactual lifespan extension. As a result, drugs that achieve longevity benefits by reducing fecundity as a result of diminished food intake are probably not useful candidates for eventual treatment of aging in humans and should be eliminated during the screening process. Drosophila melanogaster provides a suitable model system for the screening of anti-aging compounds as D. melanogaster and humans have many conserved physiological and biological pathways. In this paper, I propose an algorithm to screen anti-aging compounds using Drosophila melanogaster as a model system.

Full Text Available This article evaluates whether the legitimate defense can be used in the protection of collective environmental rights. Some scholars are contrary to the legitimate defense of those rights in face of an unlawful assault not involving concomitant aggression to individual rights. Given the current risk scenario for the global ecological balance, revealed by the approach of planetary boundaries - and taking into account its fundamental principles of protection and defense of a right – this paper does not exclude legitimate defense as a lawful means of environmental protection, regardless its impact on public order and peace.

Anti-aging effects of l-arginine

Directory of Open Access Journals (Sweden)

Mohamed Z. Gad

2010-07-01

Full Text Available l-Arginine is one of the most metabolically versatile amino acids. In addition to its role in the synthesis of nitric oxide, l-arginine serves as a precursor for the synthesis of polyamines, proline, glutamate, creatine, agmatine and urea. Several human and experimental animal studies have indicated that exogenous l-arginine intake has multiple beneficial pharmacological effects when taken in doses larger than normal dietary consumption. Such effects include reduction in the risk of vascular and heart diseases, reduction in erectile dysfunction, improvement in immune response and inhibition of gastric hyperacidity. This review summarises several positive studies and personal experiences of l-arginine. The demonstrated anti-aging benefits of l-arginine show greater potential than any pharmaceutical or nutraceutical agent ever previously discovered.

Diphtheria represents a serious infectious disease with high epidemic potential. It is a vaccine preventable disease (a minimum vaccine coverage of 95% for children of 1 year and 90% in adults could prevent the disease). Diphtheria vaccination is included in the National Immunization Program (NIP). Complete vaccination for children consists in DTaP (diphtheria toxoid, tetanus toxoid and acellular pertussis vaccine) vaccine administration from the age of 2 months until 4 years and dT vaccine (tetanus toxoid and a reduced dose of diphtheria toxoid) at 14 years old. The aim of this paper was to highlight the protection against diphtheria of an age segment of the Romanian adult population (20 to 39 years old) using a seroprevalence study. The Romanian subjects were selected from two age groups: 20-29 years (n = 219) and 30-39 years (n = 229), representative for all counties of Romania. The commercial kit Anti-Diphtheria Toxoid ELISA (IgG) (EUROIMMUN) was used to detect the antibodies of IgG class against diphtheria toxoid in the sera obtained from our subjects. We detected a 56.6% rate of positive sera (> 0.1 IU/ml--protection level) for the 20-29 age group and 31.7% positivity for the 30-39 age group. These data show a low protection level against diphtheria of the Romanian adult population, which decreases with age. The serologic data on preventable vaccine diseases are useful in order to evaluate the success of the immunization programs.

Academic leadership in nursing: legitimating the discipline in contested spaces.

McNamara, Martin S

2009-05-01

To investigate the potential of recent conceptual developments in the sociology of education for conceptualising academic leadership in nursing. During an investigation into the current status and future trajectory of academic nursing in Ireland, academic leadership emerged as a major concern for respondents. The languages of legitimation of academic leaders were elicited in in-depth interviews and analysed as expressions of underlying legitimation principles. The concept of legitimation principles provides a way of thinking about how academic nursing is positioned in the health and higher education sectors, how its leaders construct its identity, practices and purposes, and clarifies the proper focus and goals of academic leadership in nursing. Academic leadership is concerned with legitimating the discipline of nursing as an autonomous, coherent and distinctive professional and academic endeavour. This legitimacy must be secured in academic, clinical and wider contexts in which academic nursing is viewed with ambivalence; leaders must take account of the impact of nursing history on the current status and future trajectory of the discipline. The analytic tools facilitate a better understanding of the internal and external conditions under which academic nursing will flourish, or wither, in contemporary higher education.

Learning to listen. Institutional change and legitimation in UK radioactive waste policy

Energy Technology Data Exchange (ETDEWEB)

Mackerron, G. [SPRU Science and Technology Policy Research, University of Sussex, Brighton (United Kingdom); Berkhout, F. [Institute for Environmental Studies IVM, VU University, Amsterdam (Netherlands)

2009-04-15

Over the course of 50 years, UK radioactive waste policy change has been coupled with institutional change, without much progress towards the ultimate goal of safe, long-term stewardship of wastes. We explain this history as a search for legitimacy against a shifting context of legitimation needs and deficits. Following Habermas, we argue that legitimation is derived from a process of justificatory discourse. In principle, there must be a reasonable exchange of arguments between diverse parties in society, based on common norms, for legitimacy to be achieved. We show that the work of legitimation in UK radioactive waste policy has moved from a focus on factual validity claims towards an increasing emphasis on deliberative processes. This reframing of legitimation needs explains institutional and policy changes in UK radioactive waste policy. The most recent phase of policy and institutional change, which placed public deliberation about long-term management and disposal options centre-stage, represents a new step towards bridging legitimation deficits. Plans to build new nuclear reactors in the UK based on a more closed 'streamlined' decision process risk reversing the legitimacy gains that have been achieved through growing openness on radioactive waste management.

Full Text Available Toke Bek, Sidsel Ehlers Klug Department of Ophthalmology, Aarhus University Hospital, Aarhus, Denmark Purpose: Randomized clinical trials studying the effects of VEGF inhibition on wet age-related macular degeneration (wAMD are designed so that the effects of individually varying risk factors on the treatment response are eliminated. The influence of these risk factors can be studied in large data sets from real-life experience.Patients and methods: All 2,255 patients diagnosed with wAMD requiring anti-VEGF treatment in at least one eye over more than 9 years in a defined Danish population with 0.9 million inhabitants were studied. The predictive value of eye laterality, sex, current smoking status, type of anti-VEGF compound, membrane position, membrane type, leakage area, number of injections, number of visits, age, time to follow-up, visual acuity, and central retinal thickness (CRT at baseline on change in CRT after three monthly injections with anti-VEGF compound followed by treatment pro re nata for up to 12 months was assessed.Results: After 12 months, 67 patients had died, 903 had had stable CRT for at least 6 months, and 1,285 patients had not achieved stable CRT. The reduction in CRT was -84.8±118.3 µm, whereas the increase in visual acuity was 2.2±14.7 Early Treatment Diabetic Retinopathy Study letters. The risk factors included contributed to 64% of the variation in CRT reduction. High age and high CRT at baseline predicted high CRT reduction, whereas more injections, treatment with ranibizumab, and male sex predicted a low CRT reduction.Conclusion: Age, sex, and type of anti-VEGF medication can be used to plan treatment and inform patients about the expected response of anti-VEGF treatment in wAMD.

Adamus, Grazyna; Chew, Emily Y; Ferris, Frederick L; Klein, Michael L

2014-12-08

Age-related macular degeneration (AMD) is the leading cause of central vision loss in older adults. Anti-retinal autoantibodies (AAbs) have been found in individuals with AMD. The goal of the study was to determine the AAb specificity in different stages of AMD, and determine whether there is a prevalent AAb signature. Sera of 134 participants in the Age-related Eye Disease Study were analyzed for anti-retinal AAbs by western blotting. The subjects were classified by diagnostic subgroups based upon their clinical classification: No AMD, Intermediate AMD, and Late AMD - geographic atrophy (GA) and Late AMD - neovascular (NV). The presence of anti-retinal AAb was detected in 58% patients with Intermediate and Late AMD, and 54% of those with no AMD. AAbs bound to fifteen different retinal antigens. Most individuals had 1 specific AAbs (67%), with the remainder having 2 to 4 different AAbs. Over 40% of patients with Intermediate AMD, and 46% of those with GA had anti-enolase AAbs, compared with 29% of individuals with NV and 29% with no AMD. Different AAbs signatures related to NV as compared to GA and/or Intermediate AMD were distinguished. Anti-40-kDa (10%) and 42-kDa (16%) autoantibodies were associated with Intermediate AMD, while anti-30-kDa AAbs (23%) were primarily present in GA. Anti-32-kDa (12%), 35-kDa (21%), and 60-kDa (8%) AAbs were more frequent in NV AMD. A unique AAb pattern for each of the disease subgroups was present when AMD progressed from the intermediate to the late forms of severity. Differences in the frequency of specific AAbs between AMD subgroups suggested that they may participate in pathogenicity of AMD. Further studies are necessary to confirm these observations in the larger cohort and individual AMD patients over time.

[corrected] The signs of aging may originate from natural processes or from exposure to the sun, wind, or other environmental factors. To evaluate the anti-aging effects of potential agents researchers must first identify and be able to quantify epidermal markers that change with aging. This paper summarizes the results of studies conducted to evaluate the transcriptional effects of an Aframomum angustifolium seed extract and Malva Sylvestris extract, and the antiaging efficacy of a skin care product containing the Aframomum angustifolium seed extract. The transcriptional effect of an Aframomum angustifolium seed extract on normal human keratinocytes (NHKs) and normal human fibroblasts (NHF) was evaluated in vitro with the use of a low-density DNA array technology. The Malva Sylvestris extract was studied with a commercial DNA macroarray and by a real-time quantitative reverse transcriptase-polymerase chain reaction. The in vitro anti-aging activities of the Malva sylvestris extract were compared with those of all-trans retinoic acid (RA), a well-established topical therapy for photodamage and wrinkles. The genes studied were known to be modified by RA. The anti-aging efficacy of a facial skin care product containing Aframomum angustifolium seed extract was evaluated in a single-center study using image processing analysis and in a 2-center study by evaluation of the photographs by the investigator, independent evaluators, and subjects. In general, the Aframomum angustifolium seed extract strongly modified the gene expression profiles of NHKs and weakly modified the gene expression profiles of NHFs. After incubation with Aframomum angustifolium seed extract, the expressions of 3 antioxidant genes (metallothionein 1, metallothionein 2, and thioredoxin) were increased in NHKs, while expressions of 1 antioxidant gene (glutathione peroxidase) was increased in NHFs. Concerning the Malva sylvestris extract, a cDNA macro-array technology experiment with the reconstructed

As Max Weber and many others in his tradition have argued, the monopoly of the legitimate use of physical force is the core of the modern state. What counts here is not the frequency of the actual use of force but the fact that only the state has the legitimate right to use such force. The military and the police are the most concrete expressions of this monopoly. In recent decades, the use of the military and the police has been subject to external challenges – ‘globalization’ – and new idea...

Entrepreneurship as a research topic has been approached from disciplines such as economics, sociology or psychology. After justifying its study, we define the domain of the field, highlighting what has currently become its dominant paradigm, the process of the discovery, assessment and exploitation of opportunities. We then describe the main perspectives and offer an integrated conceptual framework that will allow us to legitimize the study of entrepreneurship as a field of knowledge in its own right. We believe that this framework will help researchers to better recognize the relations among the many factors forming part of the study of entrepreneurship. Lastly, we conclude with some brief reflections on the potential value of the framework presented.

Full Text Available Despite widespread beliefs that the United States has not used chemical weapons since the distant past of World War I, this study suggests a more complicated history by examining U.S. use of herbicides and incapacitating gases in the Vietnam War and its use of herbicides in the "War on Drugs." This article places such use of toxic violence within a context of U.S. hegemony, by which U.S. officials have used contested forms of violence to secure geopolitical goals, but have also been pressured to comply with humanitarian norms or-when there is a gap between norms and state policy-to do legitimating work in order to maintain domestic and international consent. Based on case study analysis of archival and secondary sources, this article identifies three main techniques U.S. officials use to legitimate contested forms of violence. These techniques are defensive categorization, humanitizing discourse, and surrogacy.

Benefits of Anti-Aging Actives in Sunscreens

2017-01-01

Full Text Available Sunscreens are functional, utilitarian, cosmetic products. The criteria of purchase are different from those for skin care and make-up. Companies are trying to add glamour and value to basic sunscreens by incorporating “active” ingredients (other than UV filters into these formulas and by communicating about the additional benefits, be they anti-aging, moisturizing, firming, anti-wrinkle, etc. While some of these ideas of additional ingredients make sense as supplementary skin protection, some others do not afford much benefit in view of the infrequent application and short period of usage. The present article reviews some of these ideas and presents a few active ingredients that might be of value in such a context, even if substantiation of such additional claims in sunscreens is often lacking.

Institutionalizing telemedicine applications: the challenge of legitimizing decision-making.

Zanaboni, Paolo; Lettieri, Emanuele

2011-09-28

During the last decades a variety of telemedicine applications have been trialed worldwide. However, telemedicine is still an example of major potential benefits that have not been fully attained. Health care regulators are still debating why institutionalizing telemedicine applications on a large scale has been so difficult and why health care professionals are often averse or indifferent to telemedicine applications, thus preventing them from becoming part of everyday clinical routines. We believe that the lack of consolidated procedures for supporting decision making by health care regulators is a major weakness. We aim to further the current debate on how to legitimize decision making about the institutionalization of telemedicine applications on a large scale. We discuss (1) three main requirements--rationality, fairness, and efficiency--that should underpin decision making so that the relevant stakeholders perceive them as being legitimate, and (2) the domains and criteria for comparing and assessing telemedicine applications--benefits and sustainability. According to these requirements and criteria, we illustrate a possible reference process for legitimate decision making about which telemedicine applications to implement on a large scale. This process adopts the health care regulators' perspective and is made up of 2 subsequent stages, in which a preliminary proposal and then a full proposal are reviewed.

Rice Water: A Traditional Ingredient with Anti-Aging Efficacy

Full Text Available The skin healing benefits of rice have been known for centuries. Rice (Oryza sativa water is a food processing waste that can potentially be incorporated into cosmetic formulations. However, no scientific evidence supports their role in skincare products. The aim of this project is to design and develop a topical gel formulation containing rice water and to evaluate its biological properties, namely, the anti-aging and antioxidant rice water properties. Rice water was evaluated in terms of physico-chemical composition and in terms of in vitro biological antioxidant activity and elastase inhibitory effect. Rice water was incorporated into a hydrogel and the developed formulation was subjected to pharmacotechnical tests such as pH and viscosity. Biological and sensory effects were evaluated on a panel of 12 volunteers for 28 days. The safety evaluation study was performed on rice water gel, using the Human Repeat Insult Patch test protocol. Rice water presented in vitro biological antioxidant activity and elastase inhibitory effect. The gel formulation containing 96% rice water was biocompatible with the human skin and presented suitable cosmetic properties. Rice water should be thus considered as an anti-aging ingredient to be used as raw material for skincare applications.

The Protection of Legitimate Expectations in Administrative Law: A Horizontal Perspective

Full Text Available The term “protection of legitimate expectations” in administrative law traditionally draws our attention to vertical relationships between the State and an individual. In my text I propose a non-traditional approach to the issue of protection of legitimate expectations in administrative law. Instead of analysing the problem from the perspective of the relationship between the administrative body and the individual, I have attempted to tackle the problem from the perspective of entities involved in peer relationships.

Anti-aging effects of vitamin C on human pluripotent stem cell-derived cardiomyocytes.

Human pluripotent stem cells (hPSCs) have arisen as a source of cells for biomedical research due to their developmental potential. Stem cells possess the promise of providing clinicians with novel treatments for disease as well as allowing researchers to generate human-specific cellular metabolism models. Aging is a natural process of living organisms, yet aging in human heart cells is difficult to study due to the ethical considerations regarding human experimentation as well as a current lack of alternative experimental models. hPSC-derived cardiomyocytes (CMs) bear a resemblance to human cardiac cells and thus hPSC-derived CMs are considered to be a viable alternative model to study human heart cell aging. In this study, we used hPSC-derived CMs as an in vitro aging model. We generated cardiomyocytes from hPSCs and demonstrated the process of aging in both human embryonic stem cell (hESC)- and induced pluripotent stem cell (hiPSC)-derived CMs. Aging in hESC-derived CMs correlated with reduced membrane potential in mitochondria, the accumulation of lipofuscin, a slower beating pattern, and the downregulation of human telomerase RNA (hTR) and cell cycle regulating genes. Interestingly, the expression of hTR in hiPSC-derived CMs was not significantly downregulated, unlike in hESC-derived CMs. In order to delay aging, vitamin C was added to the cultured CMs. When cells were treated with 100 μM of vitamin C for 48 h, anti-aging effects, specifically on the expression of telomere-related genes and their functionality in aging cells, were observed. Taken together, these results suggest that hPSC-derived CMs can be used as a unique human cardiomyocyte aging model in vitro and that vitamin C shows anti-aging effects in this model.

Legitimizing Blacks in Philosophy

Directory of Open Access Journals (Sweden)

Jameliah Shorter-Bourhanou

2017-12-01

Full Text Available In its efforts toward improving diversity, the discipline of philosophy has tended to focus on increasing the number of black philosophers. One crucial issue that has received less attention is the extent to which black philosophers are delegitimized in the discipline because their philosophical contributions challenge the status quo. A systematic problem that bars black philosophers from equal and full participation, this delegitimization precludes the emergence of genuine diversity and reveals the importance of interrogating broader attitudes toward black philosophical contributions. In this essay, I argue for radical systematic changes to disciplinary hallmarks of professionalization such as pedagogy, mentoring, publishing, and hiring practices with the aim of legitimizing black philosophers and their contributions.

This paper presents findings from a qualitative descriptive study that explored the professional socialization experiences of Licensed Practical Nurses (LPNs) who attended an online university to earn a Baccalaureate degree in nursing (BN), a prerequisite to writing the Canadian Registered Nurse (RN) qualifying exam. The project was framed from a constructivist worldview and Haas and Shaffir's theory of legitimation. Participants were 27 nurses in a Post-LPN to BN program who came from across Canada to complete required practicums. Data was collected from digital recordings of four focus groups held in different cities. Transcripts were analyzed for themes and confirmed with participants through member checking. Two overarching themes were identified and are presented to explain how these unique adult learners sought to legitimize their emerging identity as Registered Nurses (RNs). First, Post-LPN to BN students need little, if any, further legitimation to affirm their identities as “nurse.” Second, practicum interactions with instructors and new clinical experiences are key socializing agents.

Rachul, Christen M; Percec, Ivona; Caulfield, Timothy

2015-08-01

The hype surrounding stem cell science has created a market opportunity for the cosmetic industry. Cosmetic and anti-aging products and treatments that make claims regarding stem cell technology are increasingly popular, despite a lack of evidence for safety and efficacy of such products. This study explores how stem cell-based products and services are portrayed to the public through online sources, in order to gain insight into the key messages available to consumers. A content analysis of 100 web pages was conducted to examine the portrayals of stem cell-based cosmetic and anti-aging products and treatments. A qualitative discourse analysis of one web page further examined how language contributes to the portrayals of these products and treatments to public audiences. The majority of web pages portrayed stem cell-based products as ready for public use. Very few web pages substantiated claims with scientific evidence, and even fewer mentioned any risks or limitations associated with stem cell science. The discourse analysis revealed that the framing and use of metaphor obscures the certainty of the efficacy of and length of time for stem cell-based anti-aging technology to be publicly available. This study highlights the need to educate patients and the public on the current limits of stem cell applications in this context. In addition, generating scientific evidence for stem cell-based anti-aging and aesthetic applications is needed for optimizing benefits and minimizing adverse effects for the public. Having more evidence on efficacy and risks will help to protect patients who are eagerly seeking out these treatments. © 2015 The American Society for Aesthetic Plastic Surgery, Inc.

[Dutch parliament legitimizes harmful quackery].

Science.gov (United States)

van Dam, Frits S A M; Renckens, Cees N M

2010-01-01

The Dutch parliament has recently accepted a tax law in which certain groups of alternative therapists can be exempt from VAT. To be eligible for this VAT exemption, the disciplines to which the therapists belong have to meet certain training requirements. In this article it is contended, in agreement with the Royal College of Physicians in the UK, that statutory regulation is inappropriate for disciplines whose therapies are neither of proved benefit nor appropriately tested. It legitimizes harmful therapies. This is illustrated by two serious accidents, previously described in this journal, caused by a chiropractor and a craniosacral therapist.

The Legitimation of Violence

Geraldo Miniuci

2012-09-01

Full Text Available This text is oriented by the following questions: What is terrorism? How does it differ from other legitimized violent acts committed during war or in the course of a revolution? In order to answer them, this article discusses, first, the legitimacy of violence and the moral judgment of it; second, it will address the distinction between terrorist acts, acts of war, common crimes and revolutionary action, on the one hand, and the concept of innocent victim and the legitimacy of the target, on the other. In short, a new classification for terrorism will be seen, which will appear as a tactic used by political groups, as well as by public authorities, in the course of a revolution or during a war.

Full Text Available Ischemic stroke is a common neurological disorder and the burden in the world is growing. This study aims to explore the effect of sex and age difference on ischemic stroke using integrated microarray datasets. The results showed a dramatic difference in whole gene expression profiles and influenced pathways between males and females, and also in the old and young individuals. Furthermore, compared with old males, old female patients showed more serious biological function damage. However, females showed less affected pathways than males in young subjects. Functional interaction networks showed these differential expression genes were mostly related to immune and inflammation-related functions. In addition, we found ARG1 and MMP9 were up-regulated in total and all subgroups. Importantly, IL1A, ILAB, IL6 and TNF and other anti-stroke target genes were up-regulated in males. However, these anti-stroke target genes showed low expression in females. This study found huge sex and age differences in ischemic stroke especially the opposite expression of anti-stroke target genes. Future studies are needed to uncover these pathological mechanisms, and to take appropriate pre-prevention, treatment and rehabilitation measures.

Aging is associated with common conditions, including cancer, diabetes, cardiovascular disease, and Alzheimer's disease. The type of multi-targeted pharmacological approach necessary to address a complex multifaceted disease such as aging might take advantage of pleiotropic natural polyphenols affecting a wide variety of biological processes. We have recently postulated that the secoiridoids oleuropein aglycone (OA) and decarboxymethyl oleuropein aglycone (DOA), two complex polyphenols present in health-promoting extra virgin olive oil (EVOO), might constitute a new family of plant-produced gerosuppressant agents. This paper describes an analysis of the biological activity spectra (BAS) of OA and DOA using PASS (Prediction of Activity Spectra for Substances) software. PASS can predict thousands of biological activities, as the BAS of a compound is an intrinsic property that is largely dependent on the compound's structure and reflects pharmacological effects, physiological and biochemical mechanisms of action, and specific toxicities. Using Pharmaexpert, a tool that analyzes the PASS-predicted BAS of substances based on thousands of "mechanism-effect" and "effect-mechanism" relationships, we illuminate hypothesis-generating pharmacological effects, mechanisms of action, and targets that might underlie the anti-aging/anti-cancer activities of the gerosuppressant EVOO oleuropeins.

Schilling, J D

2009-01-01

An approach for ensuring legitimate data transfers of an individual within a remote healthcare solution. Biometric traits and networking are discussed for clarification of the approach. In this approach, a biometric solution is identified as a fingerprint scanner for use in a personal area network of the patient's home. Secure data exchange is acknowledged as a potential weakness in the transferring of patient data within this network. Some options are discussed to ensure security of data for the review by the caregiver. Example approaches regarding legitimacy are identified using a pulse oximeter [1], a blood pressure meter, and a weight scale as the remote patient devices in the remote healthcare solution.

ISSUES OF LEGITIMIZING POLITICAL POWER IN THE FIRST HALF OF THE TWENTIETH CENTURY: MAX WEBER AND KARL JASPERS

Directory of Open Access Journals (Sweden)

Nicolae IUGA

2012-12-01

Full Text Available The issue of legitimizing political power has specific dimensions determined by the historical context. In the period following the First World War, democratic regimes dramatically collapsed due to ample protest movements against the political establishment from different countries, but also as a result of a serious political legitimation crisis, thus making way for the rise of totalitarian regimes of Fascism and Nazism. That time debates on the problem of legitimization political power are symptomatic. Due to the general perception regarding corruption in politics and to the political incapacity to deal with social problems, we can witness a decrease of trust in contemporary democratic regimes.In order to exemplify, in a brief expositive manner, my paper will present the topic of political legitimation approached by Max Weber and Karl Jaspers, in a selection of relevant texts issued by both authors during 1919-1931. The aim of this paper is to highlight the actuality, the validity of Weber’s and Jasper’s statements and also their capacity to give pertinent responses to questions such as: What role do the common values play in the legitimating of power in a democratic society? Are there any kinds of limits regarding the electoral legitimation? How can we make the difference between a legitimate appeal and an illegitimate one, between civism and terrorism?

The role of legitimation in the professional socialization of second-year undergraduate athletic training students.

2008-01-01

Professional socialization during formal educational preparation can help students learn professional roles and can lead to improved organizational socialization as students emerge as members of the occupation's culture. Professional socialization research in athletic training is limited. To present the role of legitimation and how it influences the professional socialization of second-year athletic training students. Modified constructivist grounded theory and case study methods were used for this qualitative study. An accredited undergraduate athletic training education program. Twelve second-year students were selected purposively. The primary sample group (n = 4) was selected according to theoretical sampling guidelines. The remaining students made up the cohort sample (n = 8). Theoretically relevant data were gathered from 14 clinical instructors to clarify emergent student data. Data collection included document examination, observations, and interviews during 1 academic semester. Data were collected and analyzed through constant comparative analysis. Data triangulation, member checking, and peer-review strategies were used to ensure trustworthiness. Legitimation from various socializing agents initiated professional socialization. Students viewed trust and team membership as rewards for role fulfillment. My findings are consistent with the socialization literature that shows how learning a social or professional role, using rewards to facilitate role performance, and building trusting relationships with socializing agents are important aspects of legitimation and, ultimately, professional socialization.

Group differences in the legitimization of inequality: Questioning the role of social dominance orientation.

Science.gov (United States)

Pehrson, Samuel; Carvacho, Héctor; Sibley, Chris G

2017-03-01

Social dominance orientation (SDO) is conceived as an individual's level of support for group-based hierarchy in general that causes support for more specific group hierarchies. According to social dominance theory, group differences in SDO underpin ideological and behavioural group differences related to specific group hierarchies. Using representative 5-year longitudinal panel data from New Zealand (N = 3,384), we test whether SDO mediates effects of sex and ethnicity on legitimizing myths (LMs) relating to gender and ethnic hierarchy over time. The SDO mediation hypothesis is supported in the case of hostile sexism. However, it is unsupported in the case of benevolent sexism and LMs relating to ethnic hierarchy, where there was no cross-lagged effect of SDO. Moreover, being in the dominant ethnic group is associated with more legitimization of ethnic hierarchy but less legitimization of gender hierarchy, which is inconsistent with the notion of a general orientation underpinning group differences in legitimation. There was mixed evidence for a reverse path whereby specific LMs mediate group differences in SDO across time. We argue for the need to find alternative ways to theorize ideological consensus and difference between groups. © 2016 The British Psychological Society.

To examine the relations between the use of nonaspirin, nonsteroidal anti-inflammatory drugs (NSAIDs) and aspirin and age-related change in multiple domains of cognitive function in community-dwelling individuals without dementia. Longitudinal, with measures obtained on one to 18 occasions over up to 45 years. General community. A volunteer sample of up to 2,300 participants from the Baltimore Longitudinal Study of Aging free of diagnosed dementia. At each visit, reported NSAID or aspirin use (yes/no) and tests of verbal and visual memory, attention, perceptuo-motor speed, confrontation naming, executive function, and mental status. Mixed-effects regression models revealed that NSAID use was associated with less prospective decline on the Blessed Information-Memory-Concentration (I-M-C) Test, a mental status test weighted for memory and concentration (Prelated to greater prospective decline on the Blessed I-M-C Test (Pfunction, but on only two cognitive measures. In contrast, aspirin use was associated with greater prospective cognitive decline on select measures, potentially reflecting its common use for vascular disease prophylaxis. Effect sizes were small, calling into question clinical significance, although overall public health significance may be meaningful.

Anti-Aging Potential of Phytoextract Loaded-Pharmaceutical Creams for Human Skin Cell Longetivity

Directory of Open Access Journals (Sweden)

Saima Jadoon

2015-01-01

Full Text Available The exposure to ultraviolet radiations (UVR is the key source of skin sunburn; it may produce harmful entities, reactive oxygen species (ROS, leading to aging. The skin can be treated and protected from the injurious effects of ROS by using various pharmaceutical formulations, such as cream. Cream can be loaded with antioxidants to quench ROS leading to photo-protective effects. Moreover, modern medicines depend on ethnobotanicals for protection or treatment of human diseases. This review article summarizes various in vivo antioxidant studies on herbal creams loaded with phyto-extracts. These formulations may serve as cosmeceuticals to protect skin against injurious effects of UVR. The botanicals studied for dermatologic use in cream form include Acacia nilotica, Benincasa hispida, Calendula officinalis, Camellia sinensis, Camellia sinensis, Nelumbo nucifera, Capparis decidua, Castanea sativa, Coffea arabica, Crocus sativus, Emblica officinalis Gaertn, Foeniculum vulgare, Hippophae rhamnoides, Lithospermum erythrorhizon, Malus domestica, Matricaria chamomilla L., Moringa oleifera, Morus alba, Ocimum basilicum, Oryza sativa, Polygonum minus, Punica granatum, Silybum marianum, Tagetes erecta Linn., Terminalia chebula, Trigonella foenum-graecum, and Vitis vinifera. The observed anti-aging effects of cream formulations could be an outcome of a coordinating action of multiple constituents. Of numerous botanicals, the phenolic acids and flavonoids appear effective against UVR-induced damage; however the evidence-based studies for their anti-aging effects are still needed.

Anti-aging effect of adipose-derived stem cells in a mouse model of skin aging induced by D-galactose.

Directory of Open Access Journals (Sweden)

Shengchang Zhang

Full Text Available INTRODUCTION: Glycation products accumulate during aging of slowly renewing tissue, including skin, and are suggested as an important mechanism underlying the skin aging process. Adipose-derived cells are widely used in the clinic to treat ischemic diseases and enhance wound healing. Interestingly, adipose-derived stem cells (ASCs are also effective in anti-aging therapy, although the mechanism underlying their effects remains unknown. The purpose of the present study was to examine the anti-aging effect of ASCs in a D-galactose-induced aging animal model and to clarify the underlying mechanism. MATERIALS AND METHODS: Six-week-old nude mice were subcutaneously injected with D-gal daily for 8 weeks. Two weeks after completion of treatment, mice were randomized to receive subcutaneous injections of 106 green fluorescent protein (GFP-expressing ASCs, aminoguanidine (AG or phosphate-buffered saline (PBS. Control mice received no treatment. We examined tissue histology and determined the activity of senescence-associated molecular markers such as superoxide dismutase (SOD and malondialdehyde (MDA. RESULTS: Transplanted ASCs were detectable for 14 days and their GFP signal disappeared at day 28 after injection. ASCs inhibited advanced glycation end product (AGE levels in our animal model as well as increased the SOD level and decreased the MDA level, all of which act to reverse the aging phenotype in a similar way to AG, an inhibitor of AGE formation. Furthermore, ASCs released angiogenic factors in vivo such as vascular endothelial growth factor, suggesting a skin trophic effect. CONCLUSIONS: These results demonstrate that ASCs may contribute to the regeneration of skin during aging. In addition, the data shows that ASCs provide a functional benefit by glycation suppression, antioxidation, and trophic effects in a mouse model of aging.

Zhu, Shu Yun; Jiang, Ning; Tu, Jie; Yang, Jing; Zhou, Yue

2017-09-01

In the present study, we investigated the antioxidant and anti-aging effects of Silybum marianum protein hydrolysate (SMPH) in D-galactose-treated mice. D-galactose (500 mg/kg body weight) was intraperitoneally injected daily for 7 weeks to accelerate aging, and SMPH (400, 800, 1,200 mg/kg body weight, respectively) was simultaneously administered orally. The antioxidant and anti-aging effects of SMPH in the liver and brain were measured by biochemical assays. Transmission electron microscopy (TEM) was performed to study the ultrastructure of liver mitochondri. SMPH decreased triglyceride and cholesterol levels in the D-galactose-treated mice. It significantly elevated the activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), and total antioxidant capacity (T-AOC), which were suppressed by D-galactose. Monoamine oxidase (MAO) and malondialdehyde (MDA) levels as well as the concentrations of caspase-3 and 8-OHdG in the liver and brain were significantly reduced by SMPH. Moreover, it increased Bcl-2 levels in the liver and brain. Furthermore, SMPH significantly attenuated D-galactose-induced liver mitochondrial dysfunction by improving the activities of Na+-K+-ATPase and Ca2+-Mg2+-ATPase as well as mitochondrial membrane potential (ΔΨm) and fluidity. TEM showed that the degree of liver mitochondrial damage was significantly decreased by SMPH. The results indicated that SMPH protects against D-galactose-induced accelerated aging in mice through its antioxidant and anti-aging activities.

2017-05-01

Purpose Aging is an important factor in dry-eye disease that has not been studied in the context of therapeutic measures. Aging-associated modifications of the ocular immune system implicate that anti-inflammatory therapies may act differently among younger individuals in terms of onset and effect of different substances. The goal of this study was to determine differences in clinical phenotype and topical anti-inflammatory therapy using a desiccating stress mouse model. Methods An experimental dry-eye disease (desiccating stress model) was induced in 12-week and 12-month-old female BALB/c mice. Topical therapy included 0.05% cyclosporine/F4H5 (Novaliq), F4H5, 0.05% cyclosporine (Restasis ® , Allergan) and dexamethasone (Monodex ® , Thea Pharma) for 3 consecutive weeks. A control group received no therapy whatsoever. Readout parameters included tear secretion, corneal fluorescein staining at 5 timepoints and histological analysis of goblet cell count at the end of the experiments. Results The older mice demonstrated a significantly stronger dry eye phenotype than the younger mice. Following therapy, the older mice responded to topical anti-inflammatory therapy significantly later than the younger individuals. Regarding the different substances used, cyclosporine/F4H5 showed a significantly faster decrease in corneal fluoresceine staining after only 1 week of therapy in comparison to all other groups. This substance was also superior regarding tear secretion and goblet cell count in age matched groups and in comparison to younger mice. Conclusions These experimental data support the implication that aging should be considered as an important factor in daily clinical practice. Furthermore, the differences found between substance classes, such as calcineurin antagonists and steroids, as well as different drug formulations, should be considered in future pre-clinical and clinical trials.

Intravitreal anti-VEGF therapy for neovascular age-related macular degeneration and the risk of stroke.

LENUS (Irish Health Repository)

Cleary, C A

2011-05-01

The purpose of this study was to compare the vascular event rate in AMD patients treated with an intravitreal VEGF inhibitor with a historical control group treated with photodynamic therapy. We reviewed medical records of 83 patients treated with intravitreal anti-VEGF for AMD between 2005-2007, and 60 patients treated with PDT between 2001-2004. Mean follow-up in the anti-VEGF group was 40 months versus 95 months in the PDT group. Mean age (76 +\\/- 9 years, versus 74 +\\/- 10 years, p=n.s.) and cardiovascular risk factor profile were similar. Vascular event rates in each group were 2.6 per 100 patient years versus 2.3 per 100 patient years, (p = n.s). Age over 80 years was associated with an increased risk of a vascular event (odds ratio = 1.113, p<0.05). Despite the high prevalence of risk factors in AMD patients, the incidence of vascular events was low and associated with older age rather than therapy received.

Differentiating regulation is a promising approach to agri-environmental regulation that may potentially reduce the environmental impact of agriculture at the lowest possible costs for the farmers and society, but also possesses a number of challenges. In this article, we explore the challenges...... to the legitimacy of agri-environmental regulation that occurs when the regulatory regime changes from general regulation to differentiated regulation. The analysis is based on a case study of the implementation of the Buffer zone act in Denmark – a regulation that prevents agricultural production in a 10 (later 9......) meter fringe around selected waterbodies. We distinguish between two different ways of legitimizing: Producing knowledge and participation. We conclude that to harvest some of the obvious benefits of differentiated regulation a number of challenges must be resolved, 1) ensuring legitimacy...

The role of nutraceuticals in anti-aging medicine.

2010-12-01

'Nutraceuticals' is a wide term including all kinds of food with health or medical effect. Regulations in the world on functional food and nutraceuticals are developed along with the development of new products. This nomenclature is not aligned across legal regulations in different countries. There are several theories trying to interpret the phenomenon of aging and the most interesting theory in terms of nutrition is free radical theory and the possible role of antioxidants in aging process. A large group of substances including vitamins, carotenoids, flavonoids and minerals have in vitro or in vivo clinically significant antioxidant characteristics. There is great interest in anti-aging substances derived from food, and the most popular ingredients are antioxidants, especially coenzyme Q10, phytoestrogens, probiotics and omega-3 fatty acids. These substances have beneficial effect on digestive and immune systems, and modulate inflammatory and degenerative processes in the body. The challenge in the future will be strategic combining of cosmeceuticals and nutraceuticals in order to intervene in biological aging processes and degenerative skin changes.

2014-07-01

Full Text Available The paper describes the process to produce Chitin Nanofibril-Hyaluronan nanoparticles (CN-HA, showing their ability to easily load active ingredients, facilitate penetration through the skin layers, and increase their effectiveness and safety as an anti-aging agent. Size and characterization of CN-HA nanoparticles were determined by Scanning Electron Microscopy (SEM and Zetasizer, while encapsulation efficiency and loading capacity of the entrapped ingredients were controlled by chromatographic and spectrophotometric methods. Safeness was evidenced on fibroblasts and keratinocytes culture viability by the MTT (Methylthiazol assay; anti-aging activity was evaluated in vitro measuring antioxidant capacity, anti-collagenase activity, and metalloproteinase and pro-inflammatory release; efficacy was shown in vivo by a double-blind vehicle-controlled study for 60 days on 60 women affected by photo-aging. In addition, the CN-HA nanoparticles have shown interesting possibility to be used as active ingredients, for designing and making advanced medication by the electrospinning technology, as well as to produce transparent films for food packaging, by the casting method, and can be used also in their dry form as tissues or films without adding preservatives. These unusual CN-HA nanoparticles obtained from the use of raw materials of waste origin may offer an unprecedented occasion for making innovative products, ameliorating the quality of life, reducing pollution and safeguarding the environment’s integrity.

Erythropoietin (EPO) may protect the nervous system of animals against aging damage, making it a potential anti-aging drug for the nervous system. However, experimental evidence from natural aging nerve cell models is lacking, and the efficacy of EPO and underlying mechanism of this effect warrant further study. Thus, the present study used long-term cultured primary nerve cells to successfully mimic the natural aging process of nerve cells. Starting on the 11th day of culture, cells were treated with different concentrations of recombinant human erythropoietin (rhEPO). Using double immunofluorescence labeling, we found that rhEPO significantly improved the morphology of long-term cultured primary nerve cells and increased the total number of long-term cultured primary cells. However, rhEPO did not improve the ratio of nerve cells. A 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used to measure nerve cell activity and showed that rhEPO significantly improved the activity of long-term cultured primary nerve cells. Moreover, Annexin V-fluorescein isothiocyanate (FITC)/propidium iodide (PI) double immunofluorescence labeling flow cytometry revealed that rhEPO reduced the apoptotic rate of long-term cultured primary nerve cells. Senescence-associated β-galactosidase (SA-β-gal) immunohistochemistry staining showed that rhEPO significantly reduced the aging rate of long-term cultured primary nerve cells. Immunochemistry revealed that rhEPO enhanced intracellular superoxide dismutase (SOD) activity and glutathione (GSH) abundance and reduced the intracellular malondialdehyde (MDA) level. In addition, this effect depended on the dose, was maximized at a dose of 100 U/ml and was more pronounced than that of vitamin E. In summary, this study finds that rhEPO protects long-term cultured primary nerve cells from aging in a dose-dependent manner. The mechanism of this effect may be associated with the enhancement of the intracellular anti

Methods of legitimation: how ethics committees decide which reasons count in public policy decision-making.

Science.gov (United States)

Edwards, Kyle T

2014-07-01

In recent years, liberal democratic societies have struggled with the question of how best to balance expertise and democratic participation in the regulation of emerging technologies. This study aims to explain how national deliberative ethics committees handle the practical tension between scientific expertise, ethical expertise, expert patient input, and lay public input by explaining two institutions' processes for determining the legitimacy or illegitimacy of reasons in public policy decision-making: that of the United Kingdom's Human Fertilisation and Embryology Authority (HFEA) and the United States' American Society for Reproductive Medicine (ASRM). The articulation of these 'methods of legitimation' draws on 13 in-depth interviews with HFEA and ASRM members and staff conducted in January and February 2012 in London and over Skype, as well as observation of an HFEA deliberation. This study finds that these two institutions employ different methods in rendering certain arguments legitimate and others illegitimate: while the HFEA attempts to 'balance' competing reasons but ultimately legitimizes arguments based on health and welfare concerns, the ASRM seeks to 'filter' out arguments that challenge reproductive autonomy. The notably different structures and missions of each institution may explain these divergent approaches, as may what Sheila Jasanoff (2005) terms the distinctive 'civic epistemologies' of the US and the UK. Significantly for policy makers designing such deliberative committees, each method differs substantially from that explicitly or implicitly endorsed by the institution.

The Road to Become a Legitimate Scholar: A Case Study of International PhD Students in Science and Engineering

Directory of Open Access Journals (Sweden)

Pia Bøgelund

2015-11-01

Full Text Available The purpose of the doctoral education process is to create and legitimize scholarly researchers. This transformation, from student to scholar, is widely discussed in the literature. However, recent rapid changes in university culture have resulted in less time for supervision, stricter completion deadlines, and a greater focus on efficiency and productivity. This has had an impact on this transition process, and this impact has not been widely studied. The aim of this article is to understand the consequences of the current trends for PhD students and the education of PhD students in general. The article is based on interviews with 14 international students from two different research programs at the Faculty of Engineering and Science at Aalborg University in Denmark. The case of international PhD students in a western setting is singled out as a challenging case for becoming a legitimate scholar, since they face the additional challenge of becoming socialised into their new foreign setting. Overall, the study concludes that the transition process of doctoral students is affected by the way different supervisors deal with current university trends and how PhD students fit or do not fit into their knowledge production practices. The study identifies matches or mismatches in a knowledge production perspective, quality of contact, and degree of independence of the PhD student as factors that influence whether a transition process can be marked as sound, troublesome, or lacking. Finally, the study identifies an overall risk of neglecting the more interdependent types of international PhD students. Suggestions are given as how to address this risk.

Effect of sol aging time on the anti-reflective properties of silica coatings templated with phosphoric acid

Directory of Open Access Journals (Sweden)

Wen Wen

Full Text Available Silica anti-reflective coatings have been prepared by a sol–gel dip-coating process using the sol containing phosphoric acid as a pore-forming template. The effect of the aging time of the sol on the anti-reflective properties has been investigated. The surface topography of the silica AR coatings has been characterized. With increasing sol aging time, more over-sized pores larger than 100 nm are formed in the silica coatings. These could act as scattering centers, scattering visible light and thereby lowering transmittance. The optimal aging time was identified as 1 day, and the corresponding silica coatings showed a maximum transmittance of 99.2%, representing an 8% increase compared to the bare glass substrate. Keywords: Thin films, Anti-reflective coatings, Aging, Dip-coating, Sol–gel preparation

Legitimation problems of participatory processes in technology assessment and technology policy.

Science.gov (United States)

Saretzki, Thomas

2012-11-01

Since James Carroll (1971) made a strong case for "participatory technology", scientists, engineers, policy-makers and the public at large have seen quite a number of different approaches to design and implement participatory processes in technology assessment and technology policy. As these participatory experiments and practices spread over the last two decades, one could easily get the impression that participation turned from a theoretical normative claim to a working practice that goes without saying. Looking beyond the well-known forerunners and considering the ambivalent experiences that have been made under different conditions in various places, however, the "if" and "how" of participation are still contested issues when questions of technology are on the agenda. Legitimation problems indicate that attempts to justify participation in a given case have not been entirely successful in the eyes of relevant groups among the sponsors, participants, organizers or observers. Legitimation problems of participatory processes in technology assessment and technology policy vary considerably, and they do so not only with the two domains and the ways of their interrelation or the specific features of the participatory processes. If we ask whether or not participation is seen as problematic in technology assessment and technology policy-making and in what sense it is being evaluated as problematic, then we find that the answer depends also on the approaches and criteria that have been used to legitimize or delegitimize the call for a specific design of participation.

This work constitutes a argued analysis of the publication of the article of Hertoghe et al. "Anti aging medicine, a science based, essential medicine " whose full and unreviewed publication was forced in the framework of the Belgian law on the right of reply to an earlier publication entitled " Anti-Aging Medicine: Science or Marketing? ". We confirm the absence of scientific evidence on the effectiveness of hormonal treatments used in this approach by highlighting the different techniques allowing doctors who promote this approach to make believe in their effectiveness. This is clearly to mix in one sentence established truths and unproven facts, use references inappropriately especially by misappropriation of studies on groups of patients with hormone deficiency in order to justify treatment in healthy subjects, to ignore recent references undermining ancient literature, to betray the authors' conclusions. Our critical analysis is also considering compliance with the guidelines for integrity in scientific publications.

What is good science? What goal--if any--is the proper end of scientific activity? Is there a legitimating authority that scientists mayclaim? Howserious athreat are the anti-science movements? These questions have long been debated but, as Gerald Holton points out, every era must offer its own responses. This book examines these questions not in the abstract but shows their historic roots and the answers emerging from the scientific and political controversies of this century. Employing the case-study method and the concept of scientific thematathat he has pioneered, Holton displays the broad scope of his insight into the workings of science: from the influence of Ernst Mach on twentiethcentury physicists, biologists, psychologists, and other thinkers to the rhetorical strategies used in the work of Albert Einstein, Niels Bohr, and others; from the bickering between Thomas Jefferson and the U.S. Congress over the proper form of federal sponsorship of scientific research to philosophical debates since Oswald...

Anti-aging skin care is a growing popular topic in cosmetic and aesthetic fields, and skin care rather then makeup tips draw more attention nowadays. The phenomenon of skin aging includes thinning of skin losses of elasticity and moisture, pigmented spot formation, and wrinkle development. Along with growth in age, the decreased rates of epithelium renewal and cellular recovery as well as the reduced contents of elastin, collagen, and glycosaminoglycans all contribute to creases or folds of skin. Available strategies for wrinkle treatments include topical use of skin care products with anti-aging contents, dermabrasion, laser, Botox injection, fillers injection, and facelift. Though all of these above options can provide different degrees of improvement in facial wrinkles, the cost-effect, pain of intervention therapy, and necessity of repetitive treatment may impact on choices made. Topical use of anti-aging skin products is the most convenient and cheap way to achieve skin anti-aging effect. Lycogen(TM) is an antioxidant, which can prevent the downregulation of pro-collagen I, intracellular accumulation of malondialdehyde (MDA) and achieve the aim of skin rejuvenation. Twenty-six female patients were included in our study with ages between 30 and 45. They were randomly assigned to two groups: the vehicle control group and the experimental group. Patients in the control group applied a skin care product without Lycogen(TM)to the face via sonophoresis after facial cleanser use in the morning and at night. The experimental group applied a Lycogen(TM) -containing skin care product via sonophoresis in the same time schedule. We evaluated results, including pigmented spots, wrinkles, texture, pores, and red area by VISIA on weeks 0, 1, 2, 4, 6, 8, and 10 respectively. In the aspect of pigmented spots, the experimental group showed significant difference in comparison with the vehicle control group on weeks 2, 6, 8, and 10. For wrinkles, the experimental group had

Juridical-Criminal Paternalism, Autonomy and Vulnerability: Legitimation Criteria of Paternalistic Interventions on Individual Autonomy in Criminal Matters

Directory of Open Access Journals (Sweden)

2015-12-01

Full Text Available The following paper has as objective questioning the legitimacy of state's paternalistic interventions on individual autonomy by using institutional-criminal instruments. In this path, the paper aims to understand in which cases the State is allowed to interfere in private individual lives under the justification of being promoting a well or avoiding a harm and, as well, in which cases such interference is abusive of individuals self-determination. Into this analysis, the work will study the current concepts of paternalism, the theoretical classifications on paternalistic interventions which will be useful to demonstrate admissible and inadmissible species of paternalism and Joel Feinberg and Gerald Dworkin's anti- paternalistic theories. Following, this subject will be analyzed in association with the implications of juridical-criminal goods involved in conflicts between autonomy, human vulnerabilities and paternalism, specially regarding to the (unavailability of those goods. In the end, the work intends to define legitimation criteria for paternalistic interventions inserted in criminal laws, which superimpose themselves on the individual autonomy, in order to harmonize constitutional values of respect for autonomy, protection of vulnerable individuals and the Criminal Law functions of exclusive protection of juridical goods.

The Cyto-Dot 4 HM043 kit commercialised by BMD, has replaced the Cyto-Dot HM010 kit that allowed three auto-antibodies detection (anti-Jo-1, anti-M2 and anti-ribosomal protein). Detection of anti-LKM1 auto-antibody was added. These four auto-antibodies have in common only the intracytoplasmic localisation of their respective antigen. The aim of our study was to evaluate this new kit using 104 sera and to compare our results with reference techniques (indirect immunofluorescence IF for anti-M2, anti-ribosomal protein and anti-LKM1, double immunodiffusion ID for anti-Jo-1 and anti-LKM1, western blotting WB for anti-M2) and with Cyto-Dot HM010. The one hundred and four sera were divided into five groups: Group I (n = 12) with anti-Jo-1 detected by ID; Group II (n = 28) with 26 anti-M2 positive by IF and WB, 2 anti-M2 positive only by WB; Group III (n = 10) with anti-ribosomal protein detected by IF 5 of which precipitated by ID; Group IV (n = 32) with anti-LKM1 by IF and ID divided into 18 AIH2 and 14 HCV; Group V (n = 22) consisting of 14 healthy individuals and 8 patients with hypergammaglobulinemia. Results of this study are similar to those of Cyto-Dot HM010 for the three auto-antibodies already in use. Cyto-Dot 4 is a very good anti-LKM1 confirmation method as it is ID.

“Top-down” vs. “Bottom-up”: A Dichotomy of Paradigms for the Legitimation of Public Power in the EU

Directory of Open Access Journals (Sweden)

Dellavalle Sergio

2017-11-01

Full Text Available Public power has been justified by resorting to two different kinds of legitimation: one coming from above, the other emerging from the governed. While legitimation “from above” implies that those who are vested with executive power are qualified in their function because of their allegedly higher competences, “bottom-up” legitimacy always presupposes that only citizens can properly decide on their destiny. After giving a brief account of how both legitimation strategies have developed in the history of political ideas, attention is focused on the theories regarding the legitimacy of public power in the European Union. Indeed, both strands of legitimation of public power are represented here with original proposals, according to the specificity of the supranational condition. But even more interesting is that the research into the characteristics of supranational integration has been one of the most significant fields in which the legitimation “from above” has reappeared in Western thought after a rather long period of marginality, now taking the shape of a technocratic justification. In the main section of the article, the reasons in favour of a democratic “bottom-up” legitimation of the European public power are analyzed first, then those which recur to the so-called “output legitimacy” – in other words to technocratic arguments. The last section of the contribution is dedicated to an overall assessment of the different positions.

Age transcended: a semiotic and rhetorical analysis of the discourse of agelessness in North American anti-aging skin care advertisements.

Ellison, Kirsten L

2014-04-01

Drawing from a collection of over 160 North American print advertisements for anti-aging skin care products from January to December of 2009, this paper examines the discourse of agelessness, a vision of esthetic perfection and optimal health that is continually referred to by gerontologists, cultural theorists, and scientific researchers as a state of being to which humankind can aspire. Employing critical discourse analysis through the use of semiotics and visual rhetoric, this paper explores the means through which anti-aging skin care advertisements present to their viewers a particular object of desire, looking, more specifically, at how agelessness is presented as a way out and ultimate transcendence of age. Through the analytical tools of semiotics and visual rhetoric, four visions of agelessness are identified and explored in this paper: Agelessness as Scientific Purity, Agelessness as Genetic Impulse, Agelessness as Nature's Essence, and Agelessness as Myth. Whether found in the heights of scientific purity, the inner core of our genetic impulse, the depths of nature's essence, or whether agelessness itself has reached its own, untouchable, mythic status, the advertisements in this study represent one of the most pervasive vehicles through which our current vision(s) of ageless perfection are reflected, reinforced, and suspended in a drop of cream.

Intrinsic brain activity in a resting state incorporates components of the task negative network called default mode network (DMN) and task-positive networks called attentional networks. In the present study, the reciprocal neuronal networks in the elder group were compared with the young group to investigate the differences of the intrinsic brain activity using a method of temporal correlation analysis based on seed regions of posterior cingulate cortex (PCC) and ventromedial prefrontal cortex (vmPFC). We found significant decreased positive correlations and negative correlations with the seeds of PCC and vmPFC in the old group. The decreased coactivations in the DMN network components and their negative networks in the old group may reflect age-related alterations in various brain functions such as attention, motor control and inhibition modulation in cognitive processing. These alterations in the resting state anti-correlative networks could provide neuronal substrates for the aging brain. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

The impact of available anti-glaucoma therapy on the volume and age profile of patients undergoing glaucoma filtration surgery.

LENUS (Irish Health Repository)

Keane, P A

2012-02-01

PURPOSE: To investigate whether new classes of glaucoma medication have influenced glaucoma filtration surgery over a 20-year period in the southeast region of Ireland. METHODS: All patients undergoing glaucoma filtration surgery between January 1986 and December 2005 in Waterford Regional Hospital were identified. The following data were recorded for each patient: age; sex; and type of filtration procedure. RESULTS: Over the 20-year study period two consultant ophthalmic surgeons performed a total of 760 glaucoma filtration procedures on patients aged over 20 years. The annual average number of glaucoma surgeries declined steadily, defined by availability of different topical anti-glaucoma medications, from an average of 23.75 surgeries per surgeon per year in the subperiod 1986-1995, to 21 in 1996, 20 in 1997, and 12.69 surgeries per surgeon per year in 1998-2005, these differences being statistically significant (general linear model, P<0.001). The age profile of patients did not change significantly over the course of the study period. CONCLUSIONS: The volume of patients requiring glaucoma filtration surgery under the care of two consultant ophthalmic surgeons decreased over the 20-year study period, an era in which three classes of anti-glaucoma medications were made available. However, an increase in the age profile of patients undergoing glaucoma filtration surgery during the same period was not observed. Further study is required to resolve whether introduction of the new topical anti-glaucoma medications has led to a real reduction in the demand for glaucoma filtration surgery, or has just led to the deferral of such a demand.

This study investigated the effect of riboflavin on aging in Drosophila melanogaster (fruit fly). Experimental study. Naval Medical Research Institute. Fruit fly Drosophila melanogaster. After lifelong supplement of riboflavin, the lifespan and the reproduction of fruit flies were observed. Hydrogen peroxide (H2O2) was used to mimic oxidative stress damage to fruit flies and the survival time was recorded. The activity of copper-zinc-containing superoxide dismutase (SOD1), manganese containing SOD (SOD2) and catalase (CAT) and lipofuscin (LF) content were determined. Riboflavin significantly prolonged the lifespan (Log rank χ2=16.677, Priboflavin supplement. Riboflavin prolonged the lifespan and increased the reproduction of fruit flies through anti-oxidative stress pathway involving enhancing the activity of SOD1 and CAT and inhibiting LF accumulation. Riboflavin deserves more attention for slowing human aging.

Aging of skin is associated with environmental factors such as ultraviolet rays, air pollution, gravity, and genetic factors, all of which can lead to wrinkling of skin. Previous reports suggest that the wound repair is impaired by the aging process and strategies to manipulate the age-related wound healing are necessary in order to stimulate repair. Several traditional plant extracts are well-known for their properties of skin protection and care. Piper cambodianum P. Fourn. (PPF), a member of Piperacecae, is a plant found in Vietnam that might have therapeutic properties. Therefore, the effects of PPF stem and leaf extract on aging process were investigated in vitro and in vivo. PPF extract dissolved in methanol was investigated using Western blotting, real-time quantitative reverse transcription-polymerase chain reaction, flow cytometry, and cell wound-healing assays. We assessed the anti-aging effect of PPF in mouse using the wound-healing assay. The results were analyzed by Student's unpaired t-test; *Pwound-healing effects in mice. This study demonstrated the anti-aging and wound-healing effects of PPF extract. Therefore, PPF extract represents a promising new therapeutic agent for anti-aging and wound-healing treatments.

2016-01-01

Anti-aging has always been a popular topic, and there are many claims about the existence of factors that can slow, stop, or even reverse the aging process. Siraitia grosuenorii, a local fruit in china, has been used for the treatment of gastritis, sore throats, and whooping cough in traditional Chinese medicine. The individuals who took the juice of Siraitia grosuenorii regularly had increased longevity in the Guangxi Province, which is located in the Southern part of China. In this paper, we fed mice with Siraitia grosuenorii for 10 months to identify the role of Siraitia grosuenorii in anti-aging and to investigate its corresponding mechanism. The results showed that mice fed with Siraitia grosuenorii displayed a slower aging process. The extension of the aging process was due to the enhanced function of HSCs. FACS analysis showed that the number of LSKs, LT-HSCs, ST-HSCs and MPPs from Siraitia grosuenorii mice was decreased. In vitro, a clonigenic assay showed that LT-HSCs from Siraitia grosuenorii mice increased the ability of self-renewal. Moreover, Siraitia grosuenorii mice maintained the quiescence of LSKs, decreased the level of ROS and reduced the amount of senescence associated β-gal positive cells. Furthermore, Siraitia grosuenorii mice decreased the expression of senescence-associated proteins. Siraitia grosuenorii maintained quiescence, decreased senescence and enhanced the function of HSCs, slowing the aging process of mice.

Ageing, an unanswered question in the medical field, is a multifactorial process that results in a progressive functional decline in cells, tissues and organisms. Although it is impossible to prevent ageing, slowing down the rate of ageing is entirely possible to achieve. Traditional Chinese medicine (TCM) is characterized by the nourishing of life and its role in anti-ageing is getting more and more attention. This article summarizes the work done on the natural products from TCM that are reported to have anti-ageing effects, in the past two decades. The effective anti-ageing ingredients identified can be generally divided into flavonoids, saponins, polysaccharides, alkaloids and others. Astragaloside, Cistanche tubulosa acteoside, icariin, tetrahydrocurcumin, quercetin, butein, berberine, catechin, curcumin, epigallocatechin gallate, gastrodin, 6-Gingerol, glaucarubinone, ginsenoside Rg1, luteolin, icarisid II, naringenin, resveratrol, theaflavin, carnosic acid, catalpol, chrysophanol, cycloastragenol, emodin, galangin, echinacoside, ferulic acid, huperzine, honokiol, isoliensinine, phycocyanin, proanthocyanidins, rosmarinic acid, oxymatrine, piceid, puerarin and salvianolic acid B are specified in this review. Simultaneously, chemical structures of the monomers with anti-ageing activities are listed, and their source, model, efficacy and mechanism are also described. The TCMs with anti-ageing function are classified according to their action pathways, including the telomere and telomerase, the sirtuins, the mammalian target of rapamycin, AMP-activated kinase and insulin/insulin-like growth factor-1 signalling pathway, free radicals scavenging and the resistance to DNA damage. Finally, Chinese compound prescription and extracts related to anti-ageing are introduced, which provides the basis and the direction for the further development of novel and potential drugs.

Full Text Available Abstract Background Vitiligo is an acquired depigmenting disorder due to destruction of melanocytes. Although many theories have been suggested for its pathogenesis, the role of autoimmunity is the most popular one. The association of vitiligo with autoimmune thyroid diseases and the increased prevalence of autoantibodies including thyroid autoantibodies in vitiligo favor this role. Our objective was to compare the frequency of thyroid peroxidase antibody (anti-TPO in vitiligo patients with healthy subjects in Iran. Methods Ninety-four cases of vitiligo (46 female and 48 male and 96 control subjects (49 female and 47 male were enrolled in this controlled study. Patients with known thyroid disease, history of thyroid surgery and those receiving thyroid medications were not included. The two groups were matched regarding gender and age. The demographic data, symptoms related to thyroid diseases and results of skin and thyroid examinations were recorded in a questionnaire for each subject. Thyroid function tests including free T3, free T4 and TSH-IRMA were performed. Anti-TPO levels were assessed as well. The collected data were analyzed by SPSS version-11 in vitiligo patients and subgroups according to gender, age, extent, and duration of the disease compared with the control group. Results Anti-TPO was detected in 17 (18.1% of patients affected by vitiligo, while this figure was 7 (7.3% in the control group; the difference was significant with p-value The difference of the frequency of anti-TPO was not significant regarding the duration and extent of vitiligo. In addition, there was no significant difference in the levels of free T3, free T4, and TSH in vitiligo patients compared with the control group. Conclusion According to our study, anti-TPO was shown to be significantly more common in vitiligo patients especially in young women, compared with control group. As this antibody is a relatively sensitive and specific marker of autoimmune thyroid

Discriminating Between Legitimate and Predatory Open Access Journals: Report from the International Federation for Emergency Medicine Research Committee

Full Text Available Introduction: Open access (OA medical publishing is growing rapidly. While subscription-based publishing does not charge the author, OA does. This opens the door for “predatory” publishers who take authors’ money but provide no substantial peer review or indexing to truly disseminate research findings. Discriminating between predatory and legitimate OA publishers is difficult. Methods: We searched a number of library indexing databases that were available to us through the University of California, Irvine Libraries for journals in the field of emergency medicine (EM. Using criteria from Jeffrey Beall, University of Colorado librarian and an expert on predatory publishing, and the Research Committee of the International Federation for EM, we categorized EM journals as legitimate or likely predatory. Results: We identified 150 journal titles related to EM from all sources, 55 of which met our criteria for OA (37%, the rest subscription based. Of these 55, 25 (45% were likely to be predatory. We present lists of clearly legitimate OA journals, and, conversely, likely predatory ones. We present criteria a researcher can use to discriminate between the two. We present the indexing profiles of legitimate EM OA journals, to inform the researcher about degree of dissemination of research findings by journal. Conclusion: OA journals are proliferating rapidly. About half in EM are legitimate. The rest take substantial money from unsuspecting, usually junior, researchers and provide no value for true dissemination of findings. Researchers should be educated and aware of scam journals.

Neurodegenerative disease is common and frequently occurs in elderly patients. Previous studies have shown that ginsenoside Rg1 was able to inhibit senescent of brain, but the mechanism on the brain during the treatment remains elucidated. To study the mechanism of ginsenoside Rg1 in the process of anti-aging of brain, forty male SD rats were randomly divided into normal group, Rg1 normal group, brain aging model group and Rg1 brain aging model group, each group with 10 rats (brain aging model group: subcutaneous injection of D-galactose (120 mg kg(-1)), qd for 42 consecutive days; Rg1 brain aging model group: while copying the same test as that of brain aging model group, begin intraperitoneal injection of ginsenosides Rg1 (20 mg x kg(-1)) qd for 27 d from 16 d. Rg1 normal group: subcutaneous injection of the same amount of saline; begin intraperitoneal injection of ginsenosides Rg1 (20 mg x kg(-1)) qd for 27 d from 16 d. Normal: injected with an equal volume of saline within the same time. Perform the related experiment on the second day after finishing copying the model or the completion of the first two days of drug injections). Learning and memory abilities were measured by Morris water maze. The number of senescent cells was detected by SA-beta-Gal staining while the level of IL-1 and IL-6 proinflammatory cytokines in hippocampus were detected by ELISA. The activities of SOD, contents of GSH in hippo- campus were quantified by chromatometry. The change of telomerase activities and telomerase length were performed by TRAP-PCR and southern blotting assay, respectively. It is pointed that, in brain aging model group, the spatial learning and memory capacities were weaken, SA-beta-Gal positive granules increased in section of brain tissue, the activity of antioxidant enzyme SOD and the contents of GSH decreased in hippocampus, the level of IL-1 and IL-6 increased in hippocampus, while the length of telomere and the activity of telomerase decreased in hippocampus

How do we want to grow old? Anti-ageing-medicine and the scope of public healthcare in liberal democracies.

Healthcare counts as a morally relevant good whose distribution should neither be left to the free market nor be simply imposed by governmental decisions without further justification. This problem is particularly prevalent in the current boom of anti-ageing medicine. While the public demand for medical interventions which promise a longer, healthier and more active and attractive life has been increasing, public healthcare systems usually do not cover these products and services, thus leaving their allocation to the mechanisms of supply and demand on the free market. This situation raises the question on which basis the underlying preferences for and claims to a longer, healthier life should be evaluated. What makes anti-ageing medicine eligible for public funding? In this article, we discuss the role of anti-ageing medicine with regard to the scope and limits of public healthcare. We will first briefly sketch the basic problem of justifying a particular healthcare scheme within the framework of a modern liberal democracy, focusing on the challenge anti-ageing interventions pose in this regard. In the next section, we will present and discuss three possible solutions to the problem, essentialistic, transcendental, and procedural strategies of defining the scope of public healthcare. We will suggest a procedural solution adopting essentialistic and transcendental elements and discuss its theoretical and practical implications with regard to anti-ageing medicine. © 2012 John Wiley & Sons Ltd.

Lowering the Age of Consent: Pushing Back against the Anti-Vaccine Movement.

This article examines the rise of the anti-vaccination movement, the proliferation of laws allowing parental exemptions to mandatory school vaccines, and the impact of the movement on immunization rates for all vaccines. It uses the ongoing debate about the Human Papillomavirus (HPV) vaccine as an example to highlight the ripple effect and consequences of the anti-vaccine movement despite robust evidence of the vaccine's safety and efficacy. The article scrutinizes how state legislatures ironically promote vaccination while simultaneously deferring to the opposition by promulgating broad opt-outs from mandatory vaccine laws. This article concludes by offering an alternative legislative approach to specifically combat the anti-vaccine movement's impact on HPV vaccination rates. Lowering the age of consent has not been widely attempted or proposed and provides an alternative statutory mechanism to push back against vaccine resistance. © 2016 American Society of Law, Medicine & Ethics.

Why does Retraction Watch continue to offer support to Jeffrey Beall, and legitimize his post-mortem “predatory” lists?

Directory of Open Access Journals (Sweden)

Jaime A. Teixeira da Silva

2017-07-01

Full Text Available Retraction Watch is a science watchdog that may give the impression of being both an anti-bad science and an anti-science blog. This blog has tried to legitimize its ethical stance by naming its parent organization The Center for Science Integrity Inc. (CSI, and by appointing a former Chair of the Committee on Publication Ethics (COPE, Elizabeth Wager, to the CSI board of directors. Jeffrey Beall, another science watchdog, often appears in public alongside Adam Marcus and Ivan Oransky, the CSI secretary and president, respectively, and participates in events with Wager. Beall became academically redundant on January 15, 2017. This is because his blog, which hosted a faulty, controversial and misleading list (and thus potentially libelous of “predatory” open access journals and publishers, suddenly went blank. Beall offered no apology or explanation to the public, but was offered intellectual asylum and protection by the University of Colorado, Denver, where he works as a librarian. After a grace period of almost two months, members of the global academic community have now largely lost respect for Beall because of his silence, which may be equated with irresponsibility and/or cowardice. Despite this near extinct academic status, Retraction Watch continues to laud Beall, refer to his now-defunct site and lists as valid, as many as 25 times, and even rely on the Beall blog and lists to support several of their journalistic claims. In the world of science publishing, the legitimization of a “fact” using a defunct or false (i.e., non-factual source, is equivalent to publishing misconduct, and feeds into the “false facts” and “alternative truths” epidemic in journalism that Retraction Watch is now impregnating into science publishing. Why then is Retraction Watch allowed to operate under an ethically superior platform, while expecting scientists and academics to respect basic rules of citing valid references, but while practicing

Anti-aging Friction of Carbonate Fault Mirror and its Microstructural Interpretation

Science.gov (United States)

Park, Y.; Ree, J. H.; Hirose, T.

2017-12-01

In our slide-hold-slide (SHS) friction tests on carbonate fault rocks, fault mirror (FM), light reflective mirror-like fault surface, shows almost zero or slightly negative aging rate of friction (`anti-aging' friction), whereas carbonate faults without FM exhibit a positive aging rate. We analyzed microstructures from three types of carbonate faults to explore the cause of the anti-aging friction of FM. The three types of fault rocks before SHS tests were made from Carrara marble; (i) FM, (ii) crushed gouge of former FM (CF), and (iii) gouge produced by pre-shearing of Carrara marble (PR). The fault zone of FM before SHS tests consists of sintered nanograin patches smeared into negative asperities of wall rocks (thickness up to 150 μm) and a sintered gouge layer between wall rocks (thickness up to 200 μm) that is composed of tightly-packed nanograins (50-500 nm in size) with triple junctions and angular-subangular fragments (a few-100 μm) of sintered nanograin aggregates. A straight and discrete Y-shear surface defines a boundary between the gouge layer and the nanograin patches or between the layer and wall rock. CF specimens before SHS tests are composed of patches of sintered nanograins as in FM specimens and a porous gouge layer with finer nanograins (a few-20 nm in size) and angular fragments of former FM. PR specimens before SHS tests are composed of damaged wall rocks and porous gouge with finer nanograins (a few-tens of μm). After SHS tests, sintered appearance of grains within the fault zones of CF and PR indicates the increase in interparticle bonding and also in contact area by grain aggregation. In contrast, the gouge layer of FM specimens after SHS tests consists mostly of angular fragments of sintered nanograin aggregates. The angular shape of the fragments indicates little increase in bonding and contact area between the fragments. Tightly sintered nanograins in FM specimens would have a lower chemical reactivity with their size coarser and

The Legitimation of Novel Technologies: The Case of Nanotechnology

Science.gov (United States)

Thyroff, Anastasia E.

Nanotechnology is the control, manipulation, and application of matter on an atomic and molecular level. The technology is complex and confusing to consumers, and its long-term safety and effect on the human body, as well as the environment, are unknown. However, for the past decade, nanotechnology has been used to develop consumer products and food with novel and attractive attributes. Since nanotechnology is still not well known, it is not legitimized; that is, it has not been deemed safe and accepted by society. However, the market for nanotechnology is in the legitimation process. It will take an entire network of key stakeholders playing a specific roles for nanotechnology to legitimize. Specifically, each key stakeholder will align with a certain cultural discourse to frame nanotechnology in a particular way that complements their values. In Essay 1, I follow previous market system dynamic's literature and combine Actor Network Theory (ANT), Foucault's Discourse on Power and Goffman's Frame analysis to theoretically explore what the actor network for nanotechnology looks like. Four dominate frames are identified: 1) Advancement (i.e., government), 2) Management (i.e., industry), 3) Development (i.e., academia/scientists), and 4) Informant (i.e., NGO). Essay 2 empirically explores each actor's perspective on the nanotechnology network through a total of 24 interviews. A hermeneutic approach is used to analyze the 208 page text and themes describing each actor's role from a self and other's perspective are discussed. Additionally, three overarching themes (i.e., contradiction, constance, and cutoff) emerge; these themes describe the degree of similarity in how actors view their role in the nanotechnology network compared to how other actor's view that actor's role. In Essay 3, I bring critical theory into market system's research to better contextualize market formation theories. Specifically, I discuss how critical theory can be used to supplement ANT. I

Libertarianism and the Possibility of the Legitimate State

Directory of Open Access Journals (Sweden)

Nicolás Maloberti

2009-01-01

Full Text Available The classical formulation of libertarianism seems to be incompatible with the requirements of political legitimacy. Some libertarians have endorsed this result, denying that the state is legitimate. This paper argues, however, that the particular nature of that incompatibility represents a problem for the classical formulation of libertarianism. It is argued that acknowledging the existence of a particular minimal form of positive rights might overcome the problem in question. It is further argued that acknowledgment of such positive rights would seem to provide a more adequate normative ground for making sense of some central libertarian insights and concerns.

The reported frequency of D alloimmunization in D- recipients after transfusion of D+ platelets varies. This study was designed to determine the frequency of D alloimmunization, previously reported to be an average of 5 ± 2%. A primary anti-D immune response was defined as the detection of anti-D ≥ 28 d following the first D+ platelet transfusion. Data were collected on 485 D- recipients of D+ platelets in 11 centres between 2010 and 2012. Their median age was 60 (range 2-100) years. Diagnoses included: haematological (203/485, 42%), oncological (64/485, 13%) and other diseases (218/485, 45%). Only 7/485 (1·44%; 95% CI 0·58-2·97%) recipients had a primary anti-D response after a median serological follow-up of 77 d (range: 28-2111). There were no statistically significant differences between the primary anti-D formers and the other patients, in terms of gender, age, receipt of immunosuppressive therapy, proportion of patients with haematological/oncological diseases, transfusion of whole blood-derived or apheresis platelets or both, and total number of transfused platelet products. This is the largest study with the longest follow-up of D alloimmunization following D+ platelet transfusion. The low frequency of D alloimmunization should be considered when deciding whether to administer Rh Immune Globulin to D- males and D- females without childbearing potential after transfusion of D+ platelets. © 2014 John Wiley & Sons Ltd.

Purpose To ascertain whether single nucleotide polymorphisms (SNPs) in the Vascular Endothelial Growth factor (VEGFA), Complement Factor H (CFH), and LOC387715 genes could predict outcome to anti-VEGF therapy for patients with age related macular degeneration (AMD). Methods Patients with “wet” AMD were identified by chart review. Baseline optical coherence tomography (OCT) and visual acuity (VA) data, and at least 6 months of clinical follow up after 3 initial monthly injections of bevacizumab or ranibizumab were required for inclusion. Based on OCT and VA, patients were categorized into two possible clinical outcomes: (a) responders and (b) non-responders. DNA was extracted from saliva and genotyped for candidate SNPs in the VEGFA, LOC387715, and CFH genes. Clinical outcomes were statistically compared to patient genotypes. Results 101 patients were recruited, and one eye from each patient was included in the analysis. 97% of samples were successfully genotyped for all SNPs. We found a statistically significant association between the LOC387715 A69S TT genotype and outcome based on OCT. Conclusion Genetic variation may be associated with outcome in patients receiving anti-VEGF therapy. PMID:24143065

Aging leads to hypothalamic inflammation, but does so more slowly in mice whose lifespan has been extended by mutations that affect GH/IGF-1 signals. Early-life exposure to GH by injection, or to nutrient restriction in the first 3 weeks of life, also modulate both lifespan and the pace of hypothalamic inflammation. Three drugs extend lifespan of UM-HET3 mice in a sex-specific way: acarbose (ACA), 17-α-estradiol (17αE2), and nordihydroguaiaretic acid (NDGA), with more dramatic longevity increases in males in each case. In this study, we examined the effect of these anti-aging drugs on neuro-inflammation in hypothalamus and hippocampus. We found that age-associated hypothalamic inflammation is reduced in males but not in females at 12 months of age by ACA and 17αE2 and at 22 months of age in NDGA-treated mice. The three drugs blocked indices of hypothalamic reactive gliosis associated with aging, such as Iba-1-positive microglia and GFAP-positive astrocytes, as well as age-associated overproduction of TNF-α. This effect was not observed in drug-treated female mice or in the hippocampus of the drug-treated animals. On the other hand, caloric restriction (CR; an intervention that extends the lifespan in both sexes) significantly reduced hypothalamic microglia and TNF-α in both sexes at 12 months of age. Together, these results suggest that the extent of drug-induced changes in hypothalamic inflammatory processes is sexually dimorphic in a pattern that parallels the effects of these agents on mouse longevity and that mimics the changes seen, in both sexes, of long-lived nutrient restricted or mutant mice. © 2017 The Authors.

Long-term exposure to anti-tuberculosis medication increases risk of adverse drug reactions and toxicity. The objective of this investigation was to determine factors associated with anti-tuberculosis adverse drug reactions in Lima, Peru, with special emphasis on MDR-TB medication, HIV infection, diabetes, age and tobacco use. A case-control study was performed using information from Peruvian TB Programme. A case was defined as having reported an anti-TB adverse drug reaction during 2005-2010 with appropriate notification on clinical records. Controls were defined as not having reported a side effect, receiving anti-TB therapy during the same time that the case had appeared. Crude, and age- and sex-adjusted models were calculated using odds ratios (OR) and 95% confidence intervals (95%CI). A multivariable model was created to look for independent factors associated with side effect from anti-TB therapy. A total of 720 patients (144 cases and 576 controls) were analyzed. In our multivariable model, age, especially those over 40 years (OR = 3.93; 95%CI: 1.65-9.35), overweight/obesity (OR = 2.13; 95%CI: 1.17-3.89), anemia (OR = 2.10; IC95%: 1.13-3.92), MDR-TB medication (OR = 11.1; 95%CI: 6.29-19.6), and smoking (OR = 2.00; 95%CI: 1.03-3.87) were independently associated with adverse drug reactions. Old age, anemia, MDR-TB medication, overweight/obesity status, and smoking history are independent risk factors associated with anti-tuberculosis adverse drug reactions. Patients with these risk factors should be monitored during the anti-TB therapy. A comprehensive clinical history and additional medical exams, including hematocrit and HIV-ELISA, might be useful to identify these patients.

Full Text Available Purpose: The aim of this paper is to analyze whether the decision to disclose intangible assets could be explained by Institutional Theory. Our interest is to provide evidence of his interpretative capacity through an empirical study applied to the olive oil mill industry. Design/methodology/approach: We used a mixed methodological design that combines quantitative and qualitative methods. Findings: In an industry like olive oil mills, not use to providing additional information on intangible assets on a voluntary basis, social legitimization can be seen as a long-term objective because of the lack of urgency associated to it. Instead, a more pragmatic behavior concerned with economic legitimization has been observed, such as those that have been already found. Research limitations/implications: Greater efforts should be made to complete comparative results in a specific industry as well as we consider necessary to analyze longitudinally the evolution of the relationship legitimation-disclosure of intangibles. Originality/value: The results obtained help contribute to the literature coming from Institutional Theory in the sense that the legitimization of a new practice can vary between industries according to the state of the process of its institutionalization in each of them.Objeto: El objetivo de este trabajo es analizar si la decisión de divulgar información sobre intangibles puede ser explicada por la Teoría Institucional.

The Effect of Dosage, Gestational Age and Splenectomy on Anti-IgM Interception of Prenatal B-cell Development in Sheep

Directory of Open Access Journals (Sweden)

P. McCullagh

2003-01-01

Full Text Available The administration of a single bolus of anti-IgM antibody to foetal lambs early in pregnancy produces prolonged B-cell depletion. The present study investigated this depletion by examining the effect, on B-cell development in the ileal Peyer's patches, of varying the timing and dosage of antibody administration and by supplementing anti-IgM with surgical splenectomy. The capacity of a 1 mg bolus of anti-IgM to deplete Peyer's patches of B cells was lost if its administration was deferred until two thirds of the way through pregnancy, but persisted beyond this time if weight-adjusted doses were used. Splenectomy of the foetus performed at an earlier age failed to extend the age at which a 1 mg dose of antibody remained effective. As the concentration of murine immunoglobulin in foetal serum was greatly reduced after 21 days, it is inferred that ongoing suppression of B-cell development is not dependent on the continued presence of murine immunoglobulin. The enduring nature of suppression could be attributable to a limited period during which differentiation of B cells from stem cells normally occurs, although further studies will be needed to investigate this and other possible explanations for the effect of anti-IgM treatment on prenatal B-cell development in sheep.

In Search for Anti-Aging Strategy: Can We Rejuvenate Our Aging Stem Cells?

Directory of Open Access Journals (Sweden)

Anna Meiliana

2015-08-01

Full Text Available BACKGROUND: Recent evidence suggested that we grow old partly because of our stem cells grow old as a result of mechanisms that suppress the development of cancer over a lifetime. We believe that a further, more precise mechanistic understanding of this process will be required before this knowledge can be translated into human anti-aging therapies. CONTENT: A diminished capacity to maintain tissue homeostasis is a central physiological characteristic of aging. As stem cells regulate tissue homeostasis, depletion of stem cell reserves and/or diminished stem cell function have been postulated to contribute to aging. It has further been suggested that accumulated DNA damage could be a principal mechanism underlying age-dependent stem cell decline. It is interesting that many of the rejuvenating interventions act on the stem cell compartments, perhaps reflecting shared genetic and biochemical pathways controlling stem cell function and longevity. Strategy to slow down the aging processes is based on caloric restriction refers to a dietary regimen low in calories but without undernutrition. Sirtuin (SIRT1 and 3, increases longevity by mimicking the beneficial effects of caloric restriction. SIRT3 regulates stress-responsive mitochondrial homeostasis, and more importantly, SIRT3 upregulation rejuvenates aged stem cells in tissues. Resveratrol (3,5,4’-trihydroxystilbene, a natural polyphenol found in grapes and wine, was the most powerful natural activator of SIRT1. In fact, resveratrol treatment has been demonstrated to rescue adult stem cell decline, slow down bodyweight loss, improve trabecular bone structure and mineral density, and significantly extend lifespan. SUMMARY: Tissue-specific stem cells persist throughout the entire lifespan to repair and maintain tissues, but their self-renewal and differentiation potential become dysregulated with aging. Given that adult stem cells are thought to be central to tissue maintenance and organismal

OBJECTIVE To describe the general seroprevalence of anti-Sarcocystis neurona and anti-Neospora hughesi antibodies among healthy equids by use of indirect fluorescent antibody tests and determine potential risk factors for seropositivity. DESIGN Cross-sectional study. SAMPLE Whole blood samples collected from 5,250 equids (1 sample/animal) across 18 states in the United States during October 2013. PROCEDURES Information regarding potential risk factors (geographic region, breed, primary use, sex, and age) was collected along with the blood samples. For each equid, an indirect fluorescent antibody test was used to determine serum titers of antibody against each of the 2 protozoal parasites. Mixed-effects logistic regression models were created to determine ORs for seropositivity. RESULTS The overall seroprevalence of anti-S neurona and anti-N hughesi antibodies in the tested equids was 78% and 34%, respectively. Of the equids, 31% were seropositive and 18% were seronegative for antibodies against both parasites. Factors associated with equids being seropositive for anti-S neurona antibodies were residence in the South, warmblood breed, and age > 5 years. Seroprevalence of anti-N hughesi antibodies did not differ among equids in different states across the country, but warmblood breed and age > 5 years were associated with seropositivity. CONCLUSIONS AND CLINICAL RELEVANCE With regard to risk factors for S neurona and N hughesi exposure and antibody response among tested equids, older age was not unexpected; however, the influences of warmblood breed and geographic location on seropositivity for anti-S neurona antibody but not for anti-N hughesi antibody deserve further investigation.

Full Text Available Questo testo contribuisce alla discussione sull’efficacia del reato di riciclaggio nel far fronte al fenomeno dell’infiltrazione dei flussi di denaro sporco nell’economia lecita. Sebbene la pratica di nascondere i proventi di reato in modo da evitare la persecuzione giudiziaria risalga a molto tempo addietro, il concetto giuridico di riciclaggio è relativamente recente ed è stato introdotto nei codici penali nella maggior parte del mondo a partire dalla fine degli anni ‘80. Nel frattempo, nonostante le innumerevoli novità introdotte e i cospicui emendamenti che hanno in larga parte espanso il campo di applicazione della normativa, la disciplina anti-riciclaggio è stata oggetto di un dibattito acceso a causa dell’incapacità di impedire il reinvestimento nel processo produttivo dei capitali di provenienza illecita. Questo lavoro propone un approccio critico alla questione dell’efficacia, sulla base di un caso di studio nazionale. Parole chiave: Riciclaggio di denaro sporco; disciplina anti-riciclaggio; Germania; efficacia; flussi di denaro sporco This paper contributes to the discussion on the effectiveness of the money laundering offence in tackling the infiltration of illicit financial flows in the licit economy. Despite the practice of concealing proceeds of crime to avoid prosecution dates back long time, the legal concept of money laundering is relatively recent. It has been introduced in criminal laws from the beginning of the 80ies. So far, the scope of the anti-money laundering regime has been expanded. Yet, the regulations are object of a controversial debate due to their incapacity of impeding the reinvestment of ill-gotten gains into the legitimate economy. This work proposes an alternative approach to the question of the effectiveness, on the basis of a national case study.

The increasing use of anti-Müllerian hormone (AMH) in clinic has raised concerns regarding the reliable reference range for this test. However, the reference range for AMH in normal Chinese female population has not been established. Furthermore, relationship between AMH and other clinical markers such as body mass index (BMI) and antral follicle counts (AFCs) and other sex-related hormones have not been examined in normal population-based women. We aimed to determine the age-specific reference range for serum AMH in healthy Chinese women throughout reproductive age to menopause and to estimate relationship between AMH and other clinical markers in healthy women. In this multicenter and nationwide study, advertisements were used to recruit 2055 women, aged 20 to 55 years, from 6 different regions in China; 1590 (77.37%) women met the inclusion criteria for the reference range population. We measured the baseline serum AMH levels using new Beckman Coulter Gen II assay. Serum concentration of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), testosterone (T), prolactin (PRL), progesterone (PRG), and AFCs were also determined in the follicular phase. The AMH-Age nomogram and AMH levels of different age-groups and the relationship between AMH and other clinical markers. Serum AMH concentrations declined progressively with age. A quadratic model defined as log (AMH) = (-1.970 + 0.296 × Age - 0.006 × Age(2)) fitted best the decline of AMH with age. The median AMH levels were 6.23, 5.65, 4.55, 3.74, 2.78, and 1.09 ng/mL for the 20 ≤ age women. © The Author(s) 2016.

Interventions to extend life span represent the new perspective in aging investigation. Healthy dietary habits are important modifiable factors that can favor a healthy aging phenotype. Many studies have demonstrated benefits for metabolic syndrome and type 2 diabetes mellitus resulting from the traditional Mediterranean foods. Opuntia Ficus Indica (OFI), widespread in the Mediterranean basin, belongs to the Cactaceae family. It is known for its antioxidant and anti-inflammatory properties. Moreover, products containing extracts from OFI fruits or cladodes have been used to control obesity and other metabolic parameters, such as glycemia and lipid profile. The aim of this study was to analyze the antioxidant and anti-inflammatory effect of pasta with 3% of OFI cladode extracts added to show its beneficial effect in human health. We performed a single arm longitudinal intervention study in 42 healthy volunteers, administrating 500 g/week of this functional pasta for 30 days. Our pasta had antioxidant and anti-inflammatory properties with putative effect on the aging process and related metabolic diseases. We also demonstrated a hypoglycemic effect. The results are preliminary, but it is possible to speculate that our pasta could be considered an effective food for the prevention of age-related metabolic disorders.

Objective: To detect the anti cyclic citrullinated peptide (Anti-CCP) antibody in rheumatoid arthritis (RA) patients to determine its diagnostic value in Pakistani patients. Study Design: Cross sectional study. Place and Duration of Study: Military Hospital (MH) Rawalpindi, from January 2013 to June 2015. Material and Methods: A total of 58 patients with complications of rheumatoid arthritis were recruited in the study using convenient sampling technique after their informed consent. Age and gender of the patients were recorded. Blood was collected from the patients subjected to ELISA based detection of anti-CCP and latex agglutination test for detection of Rheumatoid Factor (RF). Data obtained were analyzed using Microsoft excel 2010. Results: Among the fifty eight RA patients, 40 percent were males and 60 percent were females. Age ranged between 12 to 80 years (mean age 49.74 +- 16.81 years) of the males RA patients and was higher as compared to females (mean age 43.2 +-16.70 years). ELISA based detection of anti-CCP antibody showed that about 91 percent of RA patients were positive for anti CCP antibody. About 72 percent were positive for anti CCP antibody alone, 19 percent were positive for both anti-CCP and RF and 9 percent were positive for RF. Conclusion: The results concluded that a higher percentage of the RA patients are positive for anti-CCP antibody marking its importance as a diagnostic marker. Anti-CCP has more sensitivity as compared to RF in RA patients. (author)

The Internet has transformed scholarly publishing, most notably, by the introduction of open access publishing. Recently, there has been a rise of online journals characterized as 'predatory', which actively solicit manuscripts and charge publications fees without providing robust peer review and editorial services. We carried out a cross-sectional comparison of characteristics of potential predatory, legitimate open access, and legitimate subscription-based biomedical journals. On July 10, 2014, scholarly journals from each of the following groups were identified - potential predatory journals (source: Beall's List), presumed legitimate, fully open access journals (source: PubMed Central), and presumed legitimate subscription-based (including hybrid) journals (source: Abridged Index Medicus). MEDLINE journal inclusion criteria were used to screen and identify biomedical journals from within the potential predatory journals group. One hundred journals from each group were randomly selected. Journal characteristics (e.g., website integrity, look and feel, editors and staff, editorial/peer review process, instructions to authors, publication model, copyright and licensing, journal location, and contact) were collected by one assessor and verified by a second. Summary statistics were calculated. Ninety-three predatory journals, 99 open access, and 100 subscription-based journals were analyzed; exclusions were due to website unavailability. Many more predatory journals' homepages contained spelling errors (61/93, 66%) and distorted or potentially unauthorized images (59/93, 63%) compared to open access journals (6/99, 6% and 5/99, 5%, respectively) and subscription-based journals (3/100, 3% and 1/100, 1%, respectively). Thirty-one (33%) predatory journals promoted a bogus impact metric - the Index Copernicus Value - versus three (3%) open access journals and no subscription-based journals. Nearly three quarters (n = 66, 73%) of predatory journals had editors or

Anti-deuteron sensitivity studies at LHCb

Baker, Sophie Katherine

2018-01-01

Measurements of anti-deuterons in collider experiments can help to reduce systematic uncertainties in indirect searches for dark matter. Two predominant unknowns in these searches are the production of secondary anti-deuterons in the cosmos from spallation processes, and anti-deuteron production from annihilating dark matter. LHCb is a forward spectrometer on the LHC ring, designed to measure b-hadron decays from high energy proton-proton collisions. With the detector's excellent particle identification capabilities, deuteron and anti-deuteron measurements at LHCb could help to parametrise the two cosmological processes. Recent studies of (anti-)deuteron identification at LHCb and the prospects for measuring prompt (anti-)deuterons from pp-collisions will be presented, as well as a working analysis of b-baryrons decaying to deuterons.

Carbon footprints and legitimation strategies: Symbolism or action?

Energy Technology Data Exchange (ETDEWEB)

Hrasky, S. [Univ. of Tasmania (Australia)

2009-07-01

The term 'carbon footprint' is now firmly entrenched in the common vernacular where it tends to function ideographically, representing a range of concerns about environmental impacts and degradation. Political and consumer concern about the related issues of carbon emissions, climate change and global warming has been heightened by a number of factors. It is often claimed that, along with the US, Australia has one of the heaviest carbon footprints. However, according to KPMG's (2008) survey results only 32 per cent of the Australian companies included in its survey report specifically on their carbon footprints. Nonetheless, KPMG (2007) reports that around 85 per cent of the 500 largest listed Australian companies do report on the related issues of climate change and greenhouse gas emissions. Motivations for making such disclosures can vary widely but legitimacy theory has been used extensively to explain environmental disclosure decisions in the context of maintaining an implicit social contract between the company and its stakeholders. While, prima facie, increased levels of voluntary disclosures may be a constructive outcome there is the associated risk that, in pursuit of legitimation, such disclosure can actually 'thicken' the corporate veil. This can occur because organizational action to maintain the social contact can be both symbolic and behavioral. That is, the disclosure response might be calculated to create a positive impression of the firm's activities with no associated change in operations (symbolism) or it might convey a message about how operational changes have been effected that are more consistent with societal expectations. This study examines the disclosure strategies of large Australian companies in light of the heightened societal awareness and concern about issues related to carbon footprints. This first aim is to determine whether, consistent with a general need for legitimation, companies are addressing

The accumulation of advanced glycationend products (AGE's) in the body, due to the non-enzymatic glycation of proteins is associated with several pathological conditions like aging and diabetes mellitus. Hence a plant having anti-glycation and anti-oxidation potentials may serve as therapeutic agent for diabetic complications and aging. In this study the anti-glycation and anti-oxidation properties of crude methanolic extracts of fruits of Capsicum frutescens and Curcuma longa were investigated. Among the two C. frutescens had more anti-glycation ability with a minimum inhibitory concentration (MIC50) of 90βg/mLas compared to 324βg/mL MIC50 of C. longa. Curcuma longa had the more anti-oxidation potential i.e. 35.01, 30.83 and 28.08% at 0.5mg, 0.25mg and 0.125mg respectively.

Full Text Available The legitimation of power among small entrepreneurs toward the employees was analyzed in the region of Passo Fundo/RS; it’s a process in which these entrepreneurs consolidate working relationships to perform their functions with self-confidence. A descriptive qualitative research was done and used as method of data collection a semi-structured interview, with observation and documental analysis. Four directors of franchises in the field of language education in the northern of Rio Grande do Sul participated in the research. The collected data were submitted to an interpretative analysis that made use of the academic frame to rescue the conception of power, its role and its fountainsin the organizations. The results reinforced the difficulties in measuring the legitimation of power. The phenomenon was investigated from an array of angles and a series of related factors were identified, provokingan evolution on its understanding.It was realized that the strategies of legitimation of the power vary according to the history and leadership style of the directors creating similar results in short term, but not always attending to professionalization and expansion matters.

The free radical theory of aging suggests that cellular oxidative damage caused by free radicals is a leading cause of aging. In the present study, we examined the effects of a well-known anti-oxidant amino acid derivative, selenocysteine, in response to environmental stress and aging using Caenorhabditis elegans as a model system. The response to oxidative stress induced by H2O2 or ultraviolet irradiation was compared between the untreated control and selenocysteine-treated groups. The effect of selenocysteine on lifespan and fertility was then determined. To examine the effect of selenocysteine on muscle aging, we monitored the change in motility with aging in both the untreated control and selenocysteine-treated groups. Dietary supplementation with selenocysteine significantly increased resistance to oxidative stress. Survival after ultraviolet irradiation was also increased by supplementation with selenocysteine. Treatment with selenocysteine confers a longevity phenotype without an accompanying reduction in fertility, which is frequently observed in lifespan-extending interventions as a trade-off in C. elegans. In addition, the age-related decline in motility was significantly delayed by supplementation of selenocysteine. These findings suggest that dietary supplementation of selenocysteine can modulate response to stressors and lead to lifespan extension, thus supporting the free radical theory of aging.

Curcumin: An age-old anti-inflammatory and anti-neoplastic agent

Full Text Available Curcumin is a natural anti-inflammatory agent that has been used for treating medical conditions for many years. Several experimental and pharmacologic trials have demonstrated its efficacy in the role as an anti-inflammatory agent. Curcumin has been shown to be effective in treating chronic conditions like rheumatoid arthritis, inflammatory bowel disease, Alzheimer's and common malignancies like colon, stomach, lung, breast, and skin cancers. As treatments in medicine become more and more complex, the answer may be something simpler. This is a review article written with the objective to systematically analyze the wealth of information regarding the medical use of curcumin, the “curry spice”, and to understand the existent gaps which have prevented its widespread application in the medical community.

The gut microbiota is playing more important roles in host immune regulation than was initially expected. Since many benefits of microbes are highly strain-specific and their mechanistic details remain largely elusive, further identification of new probiotic bacteria with immunoregulatory potentials is of great interest. We have screened our collection of probiotic lactic acid bacteria (LAB) for their efficacy in modulating host immune response. Some LAB are characterized by suppression of TNF-α induction when LAB culture supernatants are added to THP-1 cells, demonstrating the LAB's anti-inflammatory potential. These suppressive materials were not inactivated by heat or trypsin. On the other hand, treatment of THP-1 directly with live bacterial cells identified a group of pro-inflammatory LAB, which stimulated significant production of TNF-α. Among those, we chose the Lactobacillus reuteri BM36301 as an anti-inflammatory strain and the L. reuteri BM36304 as a pro-inflammatory strain, and further studied their in vivo effects. We supplied C57BL/6 mice with these bacteria in drinking water while feeding them a standard diet for 20 weeks. Interestingly, these L. reuteri strains evoked different consequences depending on the gender of the mice. That is, males treated with anti-inflammatory BM36301 experienced less weight gain and higher testosterone level; females treated with BM36301 maintained lower serum TNF-α as well as healthy skin with active folliculogenesis and hair growth. Furthermore, while males treated with pro-inflammatory BM36304 developed higher serum levels of TNF-α and insulin, in contrast females did not experience such effects from this bacteria strain. The L. reuteri BM36301 was selected as an anti-inflammatory strain in vitro. It helped mice maintain healthy conditions as they aged. These findings propose the L. reuteri BM36301 as a potential probiotic strain to improve various aspects of aging issues.

Suppressing an anti-inflammatory cytokine reveals a strong age-dependent survival cost in mice.

Full Text Available BACKGROUND: The central paradigm of ecological immunology postulates that selection acts on immunity as to minimize its cost/benefit ratio. Costs of immunity may arise because the energetic requirements of the immune response divert resources that are no longer available for other vital functions. In addition to these resource-based costs, mis-directed or over-reacting immune responses can be particularly harmful for the host. In spite of the potential importance of immunopathology, most studies dealing with the evolution of the immune response have neglected such non resource-based costs. To keep the immune response under control, hosts have evolved regulatory pathways that should be considered when studying the target of the selection pressures acting on immunity. Indeed, variation in regulation may strongly modulate the negative outcome of immune activation, with potentially important fitness consequences. METHODOLOGY/PRINCIPAL FINDINGS: Here, we experimentally assessed the survival costs of reduced immune regulation by inhibiting an anti-inflammatory cytokine (IL-10 with anti-IL-10 receptor antibodies (anti-IL-10R in mice that were either exposed to a mild inflammation or kept as control. The experiment was performed on young (3 months and old (15 months individuals, as to further assess the age-dependent cost of suppressing immune regulation. IL-10 inhibition induced high mortality in old mice exposed to the mild inflammatory insult, whereas no mortality was observed in young mice. However, young mice experienced a transitory lost in body mass when injected with the anti-IL-10R antibodies, showing that the treatment was to a lesser extent also costly for young individuals. CONCLUSIONS: These results suggest a major role of immune regulation that deserves attention when investigating the evolution of immunity, and indicate that the capacity to down-regulate the inflammatory response is crucial for late survival and longevity.

Science, consumerism and bureaucracy: the new legitimations of medical professionalism

This paper argues that the means by which the profession of medicine has to legitimise itself in the context of state‐provided health services is changing in a way that may be summarised in Weberian terms as a shift from substantive to formal rationality. The traditional model for such legitimations, evident in the UK over the last 50 years, relied heavily on professional interpretation of emergent patient needs, on professional pragmatism as a means of coping with resource limitations, on un...

There is growing interest in the use of plants for the treatment and prevention of cancer. Medicinal plants are currently being evaluated as source of promising anticancer agents. In this paper, we have investigated the anticancer potential of plant Allium wallichii, a plant native to Nepal and growing at elevations of 2300-4800 m. This is the first study of its kind for the plant mentioned. The dried plant was extracted in aqueous ethanol. Phytochemical screening, anti-microbial assay, anti-oxidant assay, cytotoxicity assay and the flow-cytometric analysis were done for analyzing different phytochemicals present, anti-microbial activity, anti-oxidant activity and anti-cancer properties of Allium wallichii. We observed the presence of steroids, terpenoids, flavonoids, reducing sugars and glycosides in the plant extract and the plant showed moderate anti-microbial and anti-oxidant activity. The IC 50 values of Allium wallichii in different cancer cell lines are 69.69 μg/ml for Prostate cancer (PC3) cell line, 55.29 μg/ml for Breast Cancer (MCF-7) cell line and 46.51 μg/ml for cervical cancer (HeLa) cell line as compared to Doxorubicin (0.85 μg/ml). The cell viability assay using FACS showed that the IC 50 value of Allium wallichii for Burkitt's lymphoma (B-Lymphoma) cell line was 3.817 ± 1.99 mg/ml. Allium wallichii can be an important candidate to be used as an anticancer agent. Separation of pure compounds with bioassay guided extraction, spectrometric analysis and subsequent cytotoxicity assay of the pure bioactive compounds from Allium wallichii is highly recommended as the crude extract itself showed promising cytotoxicity.

Immunization against hepatitis B virus (HBV) has proven to be highly effective and led to significant reduction of new infections worldwide. However, protective immunity measured by anti-HBs titers may decrease to critical levels in the years after basal immunization, particularly in case of exposure to HBV variants different from the vaccine strain. We tested 400 Palestinian children between one and 19 years of age for their anti-HBs titer, challenged the immune memory of those with low or absent anti-HBs with 2 types of hepatitis B vaccines and determined thereafter the anti-HBs titer. At the age of one, 92.2% of the children presented with protective anti-HBs titers (≥10 mIU/ml) with the majority having ≥100 mIU/ml. Protective immunity was still high at ages 2 (87.5%) and 4 (95%), declining by age 5 and 6 (from 69.2% to 66.7%) and down to an average of 39.8% between the ages of 7 and 19. 160 children with a nonprotective or low immune response challenged with either the yeast-derived Engerix-B or the mammalian cell-derived preS1-containing Sci-B-Vac vaccine showed an anamnestic immune response. 92.4% and 85.9% of the children challenged with one dose Sci-B-Vac and Engerix-B presented with anti-HBs titers >100 mIU/ml respectively. Our results reveal that vaccine-induced protective anti-HBs titers against HBV decrease rapidly beyond the age of 6 in Palestinian children, but can be strongly enhanced with a single booster vaccine dose, independent of brand and antigen composition. Our data suggest that a booster vaccine dose against HBV during school years may be useful. PMID:25996579

Full Text Available Museums and cultural developments are on the rise in the Gulf region. The United Arab Emirates is home to some of the most ambitious and extravagant museum projects in the world. In this article, I consider the example of the Louvre Abu Dhabi, exploring some of its underlying dynamics and context. I focus mainly on the relationship between branding and legitimation while placing my analysis within a wider critical debate, which includes discussions on the link between museums and identity, the legitimizing role of architecture, and the various contentious concerns and controversies surrounding the Louvre Abu Dhabi project. I conclude that the United Arab Emirates and other neighbouring countries have an excellent opportunity for innovation in the cultural field if they are willing to critically and ethically found their cultural developments on an ethos of inclusivity, openness, experimentation, non-exploitation and curatorial courage.

Smart meters are being rolled out in large numbers throughout the world, with proponents claiming they are a critical step in the transition to a low-carbon economy. Yet there are significant unresolved negative reactions to smart meters, principally based on the concern that smart meters might be used to infer the private activities that occur within a dwelling. Though smart meter data is classified as personal data, and as such protected under existing data protection frameworks in the EU, there are relevant exceptions, notably where the data is required for legitimate applications associated with the performance of 'regulated duties'. This paper contributes to this debate by examining the data requirements for some of the proposed applications of smart meter data within the electricity supply industry, and investigates whether the use of personal data can be minimized or even avoided. The discussion includes system balancing, demand reduction, demand response and distribution network operation and planning, and indicates that, for most of these applications, the requirements for personal data can indeed be minimized. 'Privacy friendly' alternatives are discussed. - Highlights: ▶ Current smart meter systems provide a strong indication of occupancy. ▶ This will have important implications for external and internal home privacy. ▶ Personal data requirements within legitimate applications are discussed. ▶ 'Privacy friendly' techniques are suggested that minimize the use of personal data. ▶ Distribution network operator has strongest claim for data from each household.

Ganoderma lucidum (Leyss. ex Fr.) Karst. (Lingzhi) is a medicinal fungus used clinically in many Asian countries to promote health and longevity. Synaptic degeneration is another key mode of neurodegeneration in Alzheimer's disease (AD). Recent studies have shown the loss of synaptic density proteins in each individual neuron during the progression of AD. It was recently reported that beta-amyloid (Abeta) could cause synaptic dysfunction and contribute to AD pathology. In this study, we reported that aqueous extract of G. lucidum significantly attenuated Abeta-induced synaptotoxicity by preserving the synaptic density protein, synaptophysin. In addition, G. lucidum aqueous extract antagonized Abeta-triggered DEVD cleavage activities in a dose-dependent manner. Further studies elucidated that phosphorylation of c-Jun N-terminal kinase, c-Jun, and p38 MAP kinase was attenuated by G. lucidum in Abeta-stressed neurons. Taken together, the results prove a hypothesis that anti-aging G. lucidum can prevent harmful effects of the exterminating toxin Abeta in AD.

This study was undertaken with the aim of developing an easy and quick means of analyzing the effect of various compounds on the synthesis and secretion of human type I collagen at the protein level. A modification of the ELISA method was used on HFF-1 cells. For the proof of concept, we used thirteen compounds most of which are known to be antioxidants. Each compound was tested at concentrations of 0, 10 and 100 microM on HFF-1 cells for 24 h. Thirteen sets of experiments for each compound were performed in ANOVA with three replicates. Duncan multiple range test (DMRT) was used to compare the mean values obtained from the treatment groups. From the results it was concluded that Vitamin C, undecylenic acid, conjugated linoleic acid, glycolic acid, and citric acid at 100 microM concentration could be used for anti-wrinkling or protection from premature aging, which requires enhancement of collagen synthesis. Lactic acid, EGCG, resveratrol, and retinol that can inhibit collagen synthesis effectively in a dose-dependent manner may be used for anti-fibrosis treatment purposes.

Constructing (IlLegitimate Democracy: Populism and Power Concentration in Newspaper Discourse on Venezuela

Ernesto Abalo

2014-10-01

Full Text Available Despite scholarly consensus about the importance of the media for democracy, scant attention has been paid to what democracy means to journalistic discourse and how discourses on democracy are interrelated with legitimacy. The aim of this paper is to explore how (illegitimate democracy is constructed in newspaper discourse. By using critical discourse analysis, this paper examines foreign news items about Venezuela, a country that under the presidency of Hugo Chávez has challenged the hegemonic global political and economic orders. The analysis section focuses on two main findings about the Venezuelan government: the constructions of populism and power concentration, which serve to mark deviance from what is perceived as legitimate democracy. This paper argues that a liberal perception of democracy constitutes a central framework for the construction of (illegitimate democracy, which is revealed not least by news discourse’s focus on what is morally unacceptable political conduct according to liberal democratic norms. In this sense, such constructions serve to denounce potential governmental power abuses but also to legitimize the hegemonic economic and political orders.

Homophobia as a barrier to comprehensive media coverage of the Ugandan anti-homosexual bill.

Science.gov (United States)

Strand, Cecilia

2012-01-01

The Ugandan Anti-Homosexuality Bill of October 2009 caused an international outcry and sparked intense debate in the local media. This article explores to what degree a discriminatory social environment manifests itself in the Ugandan print media and discusses the potential implications for media's coverage of contentious policy options such as the Anti-Homosexuality Bill. A content analysis of 115 items from two daily newspapers (the government-owned New Vision and the privately owned the Daily Monitor, between October and December 2009) indicates the existence of two separate house styles; this is in spite of the fact that both newspapers reproduce the surrounding society's homophobia, albeit with different frequency. Unlike the New Vision, the Daily Monitor includes coverage on homophobia and discrimination, as well as provides space for criticism of the Bill. By acknowledging discrimination and its negative impact, the newspaper de-legitimizes homophobia and problematizes the proposed Anti-homosexuality Bill for their readers.

Anti-aging cosmetics are widely used for improving signs of aged skin such as skin wrinkles, decreased elasticity, low dermal density and yellow skin tone. The present study evaluated the effects of cosmetic formulations, eye cream and facial cream, containing palmitoyl peptides, Silybum marianum ( S. marianum ) seed oil, vitamin E and other functional ingredients on the improvement of facial wrinkles, elasticity, dermal density and skin tone after 4 weeks period of application on aged human skin. Healthy volunteers (n=20) with aged skin were recruited to apply the test materials facially twice per day for 4 weeks. Skin wrinkles, elasticity, dermal density and skin tone were measured instrumentally for assessing the improvement of skin aging. All the measurements were conducted prior to the application of test materials and at 2 and 4 weeks of treatment. Crow's feet wrinkles were decreased 5.97% after 2 weeks of test material application and 14.07% after 4 weeks of application in comparison of pre-application. Skin elasticity was increased 6.81% after 2 weeks and 8.79% after 4 weeks. Dermal density was increased 16.74% after 2 weeks and 27.63% after 4 weeks. With the L* value indicating skin brightness and the a* value indicating erythema (redness), the results showed that brightness was increased 1.70% after 2 weeks and 2.14% after 4 weeks, and erythema was decreased 10.45% after 2 weeks and 22.39% after 4 weeks. Hence, the test materials appear to exert some degree of anti-aging effects on aged human skin. There were no abnormal skin responses from the participants during the trial period. We conclude that the facial and eye cream containing palmitoyl peptides and S. marianum seed oil, vitamin E and other ingredients have effects on the improvement of facial wrinkles, elasticity, dermal density and skin tone.

Full Text Available The current study was performed to investigate mitochondrial protection and anti-aging activity of Astragalus polysaccharides (APS and the potential underlying mechanism. Lipid peroxidation of liver and brain mitochondria was induced by Fe2+–Vit C in vitro. Thiobarbituric acid (TBA colorimetry was used to measure the content of thiobarbituric acid reactive substances (TBARS. Mouse liver mitochondrial permeability transition (PT was induced by calcium overload in vitro and spectrophotometry was used to measure it. The scavenging activities of APS on superoxide anion (O2•－ and hydroxyl radical (•OH, which were produced by reduced nicotinamide adenine dinucleotide (NADH—N-Methylphenazonium methyl sulfate (PMS and hydrogen peroxide (H2O2–Fe2+ system respectively, were measured by 4-nitrobluetetrazolium chloride (NBT reduction and Fenton reaction colorimetry respectively. The Na2S2O3 titration method was used to measure the scavenging activities of APS on H2O2. APS could inhibit TBARS production, protect mitochondria from PT, and scavenge O2•－, •OH and H2O2 significantly in a concentration-dependent manner respectively. The back of the neck of mice was injected subcutaneously with D-galactose to induce aging at a dose of 100 mg/kg/d for seven weeks. Moreover, the activities of catalase (CAT, surperoxide dismutase (SOD and glutathione peroxidase (GPx and anti-hydroxyl radical which were assayed by using commercial monitoring kits were increased significantly in vivo by APS. According to this research, APS protects mitochondria by scavenging reactive oxygen species (ROS, inhibiting mitochondrial PT and increasing the activities of antioxidases. Therefore, APS has the effect of promoting health.

Cutaneous wounds are among the most common soft tissue injuries and are particularly hard to heal in aging. Caloric restriction (CR) is well documented to extend longevity; pharmacologically, profound rejuvenative effects of CR mimetics have been uncovered, especially metformin (MET), resveratrol (RSV), and rapamycin (RAPA). However, locally applied impacts and functional differences of these agents on wound healing remain to be established. Here, we discovered that chronic topical administration of MET and RSV, but not RAPA, accelerated wound healing with improved epidermis, hair follicles, and collagen deposition in young rodents, and MET exerted more profound effects. Furthermore, locally applied MET and RSV improved vascularization of the wound beds, which were attributed to stimulation of adenosine monophosphate-activated protein kinase (AMPK) pathway, the key mediator of wound healing. Notably, in aged skin, AMPK pathway was inhibited, correlated with impaired vasculature and reduced healing ability. As therapeutic approaches, local treatments of MET and RSV prevented age-related AMPK suppression and angiogenic inhibition in wound beds. Moreover, in aged rats, rejuvenative effects of topically applied MET and RSV on cell viability of wound beds were confirmed, of which MET showed more prominent anti-aging effects. We further verified that only MET promoted wound healing and cutaneous integrity in aged skin. These findings clarified differential effects of CR-based anti-aging pharmacology in wound healing, identified critical angiogenic and rejuvenative mechanisms through AMPK pathway in both young and aged skin, and unraveled chronic local application of MET as the optimal and promising regenerative agent in treating cutaneous wound defects. © 2017 The Authors.

2017-03-01

Full Text Available BACKGROUND The aim of this study was to determine and compare sexual dysfunction caused by anti-psychotics and anti-depressants in drug naïve patients. MATERIALS AND METHODS Patients diagnosed as drug naïve schizophrenic and depression as per DSM-5 criteria & age between 18-45 years were recruited and allocated into group A (n=30–receiving anti-psychotics & group B (n=30 receiving anti-depressants after informed consent by the patients. Sexual dysfunction was assessed by Arizona Sexual Experiences Scale (ASEX during the initial 2 months of therapy. RESULTS ASEX mean for patients receiving antipsychotics increased from the baseline of 7.97 to 17.23 and the ASEX mean for patients receiving antidepressants increased from baseline of 7.80 to 18.67 with p value of 0.249 which is not statistically significant. Among the antipsychotics haloperidol ASEX mean increased from 7.87 to 18.00 and risperidone mean increased from 8.07 to 16.47 with the p value of 0.335 which is not significant. More patients on haloperidol showed evidence of sexual dysfunction as assessed by ASEX scoring than risperidone though p value was not significant. Among the two antidepressants ASEX score mean for amitriptyline patients increased from 8.07 to 16.47, and that of fluoxetine from 7.53 to 16.47 with the p value of 0.018* statistically significant at α of 0.05 level. CONCLUSION This study shows presence of sexual dysfunction in patients receiving antipsychotics & antidepressants by 2 nd month of therapy though statistically not significant. Fluoxetine group patients developed statistically significant sexual dysfunction. Implications for future research about sexual dysfunction in all new treatments should be strongly taken into account because this side effect adds to the emotional stress and worsening of mental dysfunction.

Telomere shortening is considered as one of the main characteristics of cellular aging by limiting cellular division. Besides the fundamental advances through the discoveries of telomere and telomerase, which were recognized by a Nobel Prize, telomere protection remains an essential area of research. Recently, it was evidenced that studying the cross-talks between the proteins associated with telomere should provide a better understanding of the mechanistic basis for telomere-associated aging phenotypes. In this review, we discuss the current knowledge on telomere shortening, telomerase activity, and the essential role of telomere binding proteins in telomere stabilization and telomere-end protection. This review highlights the capacity of telomere binding proteins to limit cellular senescence and to maintain skin tissue homeostasis, which is of key importance to reduce accelerated tissue aging. Future studies addressing telomere protection and limitation of DNA damage response in human skin should include investigations on telomere binding proteins. As little is known about the expression of telomere binding proteins in human skin and modulation of their expression with aging, it remains an interesting field of skin research and a key area for future skin protection and anti-aging developments. © 2012 Wiley Periodicals, Inc.

To determine whether there is an association between obesity and anti-Müllerian hormone (AMH) among reproductive-aged African American women (AAW). From the women participating in an ongoing National Institute of Environmental Health Sciences study, 1,654 AAW aged 23 to 35 were included in this study. Anthropometric measurements, personal health information, and serum AMH and adipokine levels were analyzed. The median body mass index (BMI) was 32.4 kg/m 2 , and the median AMH was 3.18 ng/mL. Participants with obesity had AMH concentrations that were 23.7% lower than those with a BMI ≤25 kg/m 2 (2.9 ng/mL vs. 3.8 ng/mL). In multivariable linear regression models, current BMI (β = -0.015; 95% CI -0.021 to -0.009), BMI at age 18 (β = -0.016; 95% CI -0.024 to -0.008), heaviest reported lifetime weight (β = -0.002; 95% CI -0.003 to -0.001), and leptin (β = -0.016; 95% CI -0.025 to -0.007) were inversely associated with AMH. There was no significant association between adiponectin and AMH. AMH was significantly lower (mean log = 0.91, SE = 0.11) in participants with obesity at age 18 and at enrollment when compared with those who were underweight or normal weight at age 18 but had obesity at enrollment (mean log = 1.16, SE = 0.12). In reproductive-aged AAW there is a significant association between obesity and AMH, suggesting that excess adiposity may compromise ovarian reserve. Effects of obesity on AMH may be cumulative. © 2016 The Obesity Society.

Full Text Available BACKGROUND: Epstein-Barr Virus (EBV is a globally prevalent herpesvirus associated with infectious mononucleosis and many malignancies. The survey on EBV prevalence appears to be important to study EBV-related diseases and determine when to administer prophylactic vaccine. The purpose of this retrospective study was to collect baseline information about the prevalence of EBV infection in Chinese children. METHODOLOGY/PRINCIPAL FINDING: We collected 1778 serum samples from healthy children aged 0 to 10, who were enrolled in conventional health and nutrition examinations without any EBV-related symptom in 2012 and 2013 in North China (n = 973 and South China (n = 805. We detected four EBV-specific antibodies, i.e., anti-VCA-IgG and IgM, anti-EBNA-IgG and anti-EA-IgG, by ELISA, representing all of the phases of EBV infection. The overall EBV seroprevalence in samples from North and South China were 80.78% and 79.38% respectively. The EBV seropositivity rates dropped slightly at age 2, and then increased gradually with age. The seroprevalence became stabilized at over 90% after age 8. In this study, the seroprevalence trends between North and South China showed no difference (P>0.05, and the trends of average antibody concentrations were similar as well (P>0.05. CONCLUSIONS/SIGNIFICANCE: EBV seroprevalence became more than 50% before age 3 in Chinese children, and exceed 90% after age 8. This study can be helpful to study the relationship between EBV and EBV-associated diseases, and supportive to EBV vaccine development and implementation.

Full Text Available Objectives : To observe physiological anti-body effects of anti-BV, acute toxic response, measurement of LD50, and the effects of anti-body were evaluated. Methods : LD50 of Anti-Bee Venom were measured, and to analyze acute toxic responses, weight, and the anti-body effects various concentrations of Anti-BV were diluted and the survival rate was measured. Cell blood count (CBC, liver, spleen, and kidney pathologies were observed from the histological aspects. Results : Experiment was conducted to observe Anti-BV as the anti-body to the bee venom and the following results were obtained: 1. Anti-BV was injected intraperitoneally and no toxic responses were witnessed. All of the experiment subjects stayed alive during the experiment, making LD50 analysis impossible. 2. Anti-BV was injected intraperitoneally in mice and no significant weight changes were measured between the control group and the experiment groups. 3. Measuring the concentration dependent survival rate, the highest survival rate was at the concentration of 1.25×102mg/kg(1/2.000 for Anti-BV. 4. No particular results were shown in the CBC test. 5. Observation of changes in the organ tissues, Anti-BV was found to suppress blood stasis in the liver and inhibit necrosis of the cells. Conclusion : Above results suggest that Anti-BV doesn't cause any toxic responses in the body and works as an anti-body to the bee venom. Further studies must be followed to secure the findings.

Kalla yarning at Matagarup: Televised legitimation and the limits of heritage-making in the city

Full Text Available This paper is directed towards furthering understandings of popular television news reporting on Aboriginal solidarity gatherings at Matagarup on Heirisson Island, a state-registered Aboriginal Heritage Site in Perth, Western Australia. In doing so, it also seeks to identify the practical limits of heritage making in disrupting the legitimization of state action not recognizing such heritage claims. In 2012 and 2015, Aboriginal citizens gathering and camping at the heritage site were subject to police raids legitimized by popular media organizations reporting a breach of municipal bylaws prohibiting camping and fires on Heirisson Island. This paper examines a shift in popular television reporting over the three years towards acknowledging that Aboriginal people should be able to assemble, without police harassment, around a fire at the site. The most radical shift in reporting is observable in Nine News coverage of events. For this reason, eight televised items from Nine News in 2015 are analysed alongside Nine News reporting described in the authors’ previous study of reporting of events at Matagarup in 2012. The paper identifies and discusses the implications of two key dialogical processes in the news production: Firstly, a process of cross-cultural reading and shared understandings of fire as hearth, and secondly a process of reproducing a dominant discursive tradition locating home for Aboriginal people outside the city.

The most important risk factor for Alzheimer's disease (AD) is aging. Neurotoxicity in AD has been linked to dyshomeostasis of intracellular Ca2+ induced by small aggregates of the amyloid-β peptide 1-42 (Aβ42 oligomers). However, how aging influences susceptibility to neurotoxicity induced by Aβ42 oligomers is unknown. In this study, we used long-term cultures of rat hippocampal neurons, a model of neuronal in vitro aging, to investigate the contribution of aging to Ca2+ dishomeostasis and neuron cell death induced by Aβ42 oligomers. In addition, we tested whether non-steroidal anti-inflammatory drugs (NSAIDs) and R-flurbiprofen prevent apoptosis acting on subcellular Ca2+ in aged neurons. We found that Aβ42 oligomers have no effect on young hippocampal neurons cultured for 2 days in vitro (2 DIV). However, they promoted apoptosis modestly in mature neurons (8 DIV) and these effects increased dramatically after 13 DIV, when neurons display many hallmarks of in vivo aging. Consistently, cytosolic and mitochondrial Ca2+ responses induced by Aβ42 oligomers increased dramatically with culture age. At low concentrations, NSAIDs and the enantiomer R-flurbiprofen lacking anti-inflammatory activity prevent Ca2+ overload and neuron cell death induced by Aβ42 oligomers in aged neurons. However, at high concentrations R-flurbiprofen induces apoptosis. Thus, Aβ42 oligomers promote Ca2+ overload and neuron cell death only in aged rat hippocampal neurons. These effects are prevented by low concentrations of NSAIDs and R-flurbiprofen acting on mitochondrial Ca2+ overload.

Fertility is referred to the capability for having offspring and can be evaluated by fertility rate. Women's fertility is strictly dependent on individual's age. The fertility peak occurs in the early 20s, and it starts to decline in the third and fourth decades of life (falling sharply after age 35). The aim of this work is to review the available data concerning fertility in women of late reproductive age, especially the role of serum anti-Müllerian hormone (AMH) levels. There are a lot of factors responsible for decrease of fertility in women of late reproductive age. These factors can be classified as oocyte-dependent (decrease in oocyte quantity and quality) and oocyte-independent (reproductive organs [uterus, oviducts] status and general health). Anti-Müllerian hormone (AMH) is a dimeric glycoprotein of the transforming growth factor-β (TGF-β) superfamily produced directly by the ovarian granulosa cells of secondary, preantral, and early antral follicles. It has been used as an ovarian reserve marker since 2002. Anti-Müllerian hormone seems to be the best endocrine marker for assessing the age-related decline of the ovarian pool in healthy women. Evaluation of AMH's predictive value in the naturally aging population is important for counseling women about reproductive planning as well as for treatment planning for women experiencing hormone-sensitive gynecological conditions such as endometriosis and fibroids. AMH can be considered as an indicator of fertility in late reproductive age women and pregnancy outcome in assisted reproductive technology cycles. AMH can strongly predict poor response in the controlled ovarian stimulation.

In the modern society, aging had been a major problem. People may rely on many medicines to delay it. However, lots of medicines were chemosynthetic, and they would do a bad side-effect on human body. Microbial sources could be used as a potential means of producing natural antioxidants. Lentinus edodes, commercial obtained in daily life, had recently become more attractive in physiological research. Zinc was now considered as a major element in assuring the correct functioning of an organism and essential for maintaining coordination of the major homeostatic networks. To investigate the bioconversion of zinc and the physiological effects of their complex (MZPS), the present studies were processed. Mycelia polysaccharides (MPS) and mycelia zinc polysaccharides (MZPS) of Lentinus edodes SD-08 were extracted by hot water leaching and purified by DEAE-52 cellulose anion-exchange column chromatography separately. The zinc content was determined by flame atomic absorption spectrometry. The evaluation of monosaccharide compositions and proportions used gas chromatogram. The analysis of molecular weight used HPGPC chromatogram. The typical structure of polysaccharide was evaluated by IR spectrum. The antioxidant activities in vitro measured through reducing power, the scavenging effects on hydroxyl radical and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals. The anti-aging activities in vivo measured through the total antioxidant capacity (T-AOC), GSH peroxide (GSH-Px), superoxide dismutase (SOD) and the contents of malondialdehyde (MDA). MPS and MZPS of Lentinus edodes SD-08 were extracted and purified by DEAE-52 cellulose anion-exchange column chromatography separately, and four fractions (MPS-1, MPS-2, MZPS-1 and MZPS-2) were obtained. In addition, MPS composing of rhamnose, arabinose and mannose (molar proportion = 1.75:1.00:3.02) and MZPS containing rhamnose, arabinose, mannose and glucose (molar proportion = 7.19:2.26:1.00:8.39) were investigated by gas chromatography

Full Text Available AIM:To evaluate the visual function evolution of retinal pigment epithelial (RPE tears in patients with age-related macular degeneration (AMD according to type of occurrence [spontaneous or secondary to anti-vascular endothelial growth factor (anti-VEGF injection] and the topographic location of the tear after a two-year follow-up period.METHODS:A total of 15 eyes of 14 patients with RPE tears in exudative AMD were analyzed retrospectively at the University Eye Clinic of Trieste. Inclusion criteria were:patient age of 50 or older with AMD and RPE tears both spontaneous occurring or post anti-VEGF treatment. Screening included:careful medical history, complete ophthalmological examination, fluorescein angiography (FA, indocyanine green angiography (ICG, autofluorescence and infrared imaging and optical coherence tomography (OCT. Patients were evaluated every month for visual acuity (VA, fundus examination and OCT. Other data reported were:presence of PED, number of injections before the tear, location of the lesion.RESULTS: Mean follow-up was 24wk (SD±4wk. A total of 15 eyes were studied for RPE tear. In 6 cases (40%, the RPE tears occurred within two years of anti-VEGF injections the others occurred spontaneously. In 13 cases (86.6%, the RPE tear was associated with pigment epithelial detachment (PED. In 7 cases (46.6%, the RPE tear occurred in the central area of the retina and involved the fovea. Two lesions were found in the parafoveal region, six in the extra-macular area. In all cases visual acuity decreased at the end of the follow-up period (P<0.01 independently of the type or the topographical location of the lesion.CONCLUSION:RPE tear occurs in exudative AMD as a spontaneous complication or in relation to anti-VEGF injections. Visual acuity decreased significantly and gradually in the follow-up period in all cases. No correlation was found between visual loss and the type of onset or the topographic location of the tears.

The aim of the present study was to optimize the purification of mycelia selenium polysaccharides (MSPS) from Agrocybe cylindracea SL-02 and characterize their in vitro antioxidant and in vivo anti-ageing activities. The Box-Behnken experimental design (BBD) was evaluated, which showed that the optimum conditions included an extraction temperature of 94.99°C, a pH of 9 and a precipitation temperature of 12°C, and the predicted yield was 11.036 ± 0.31%. The in vitro antioxidant assay demonstrated that MSPS had potential effects on scavenging and enhanced the reducing power of reactive oxygen species. The in vivo anti-ageing evaluation showed that MSPS significantly reduced the malonaldehyde (MDA) contents and total cholesterol (CHOL) levels, and remarkably improved the activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and total antioxidant capacity (T-AOC) in mice in response to D-galactose-induced ageing. Furthermore, the characteristic analysis of MSPS indicated a selenium content of 1.76 ± 0.10 mg/g at a concentration of 6 μg/mL in liquid media and a monosaccharide composition of rhamnose, arabinose, mannose, glucose and galactose at a molar ratio of 29:3:1:18.8:2.7. These results suggest that MSPS might be suitable for functional foods and natural drugs on preventing the ageing progress induced by toxic chemicals. PMID:27532123

Utilizing primary socialization theory (PST) and longitudinal survey data from 381 Latina/o sixth- through eighth-grade students, we hypothesized that four types of parent anti-substance use messages (i.e., parents' own past substance use, religious beliefs, respect for family, and peer resistance) would discourage Latina/o students' substance use, particularly when the students perceived their parents' anti-substance use messages were legitimate. The results supported moderation. For Latina/o students who thought that their parents' anti-substance use messages were legitimate, many of the anti-substance use messages were negatively related to substance use, but the associations were positive or nonsignificant for Latina/o students who thought that their parents' anti-substance use messages were not legitimate. The findings extend past work on PST and anti-substance use parent-child communication, highlighting the importance of perceived legitimacy and message content.

Following the classic economic model of tax evasion, taxpayers base their tax decisions on economic determinants, like fine rate and audit probability. Empirical findings on the relationship between economic key determinants and tax evasion are inconsistent and suggest that taxpayers may rather rely on their beliefs about tax authority's power. Descriptions of the tax authority's power may affect taxpayers' beliefs and as such tax evasion. Experiment 1 investigates the impact of fines and beliefs regarding tax authority's power on tax evasion. Experiments 2-4 are conducted to examine the effect of varying descriptions about a tax authority's power on participants' beliefs and respective tax evasion. It is investigated whether tax evasion is influenced by the description of an authority wielding coercive power (Experiment 2), legitimate power (Experiment 3), and coercive and legitimate power combined (Experiment 4). Further, it is examined whether a contrast of the description of power (low to high power; high to low power) impacts tax evasion (Experiments 2-4). Results show that the amount of fine does not impact tax payments, whereas participants' beliefs regarding tax authority's power significantly shape compliance decisions. Descriptions of high coercive power as well as high legitimate power affect beliefs about tax authority's power and positively impact tax honesty. This effect still holds if both qualities of power are applied simultaneously. The contrast of descriptions has little impact on tax evasion. The current study indicates that descriptions of the tax authority, e.g., in information brochures and media reports, have more influence on beliefs and tax payments than information on fine rates. Methodically, these considerations become particularly important when descriptions or vignettes are used besides objective information.

Ninety-five patients had ExRA and 130 had no ExRA. There was no association of anti-CCP and anti-MCV levels with the presence of ExRA as total group (P=0.40 and P=0.91, resp.. Making an analysis of individual manifestations, rheumatoid nodules were associated with positivity for rheumatoid factor (RF; (P=0.01, anti-CCP (P=0.048, and anti-MCV (P=0.02. Instead, RF, anti-CCP, or anti-MCV were not associated with SS, chronic anemia, or peripheral neuropathy. Levels of anti-CCP correlated with the score of the Health Assessment Questionnaire-Disability Index (HAQ-Di (r=0.154, P=0.03, erythrocyte sedimentation rate (ESR; (r=0.155, P=0.03, and RF (P=0.254, P<0.001, whereas anti-MCV titres only correlated with RF (r=0.169, P=0.02. On adjusted analysis, ExRA was associated with longer age (P=0.015, longer disease duration (P=0.007, higher DAS-28 score (P=0.002, and higher HAQ-DI score (P=0.007, but serum levels of anti-CCP and anti-MCV were not associated. These findings show the need to strengthen the evaluation of the pathogenic mechanisms implied in each specific ExRA manifestation.

Aging is usually associated with increased levels of oxidants, and may result in damages caused by oxidative stress. There is a direct relationship between aging and increased incidence of inflammatory diseases. The present research intended to study the anti-aging and anti-inflammatory effects of the drug G2013 (guluronic acid) at low and high doses on the genes expression of a number of enzymes involved in oxidative stress (including SOD2, GPX1, CAT, GST, iNOS, and MPO) in peripheral blood mononuclear cells (PBMCs) of healthy individuals under in vitro conditions. Venous blood samples were taken from 20 healthy individuals, the PBMCs were isolated and their RNAs extracted and their cDNAs were synthesized, and the genes expression levels were measured using the qRT-PCR technique. Our results indicated that this drug could, at both low and high doses, significantly reduce the expression of the genes for SOD2, GPX1, CAT, and GST compared to the LPS group (phealthy gene expression, and possibly it might reduce the pathological process of aging and age-related inflammatory diseases.

Full Text Available This paper discusses the exhibition Jerusalem at the Museum of World Culture (MoWC in Gothenburg, Sweden. The exhibition mixes photographs of LGBTQ (LesbianGayBiTransQueer persons in Jerusalem, with quotes from the three Abrahamitic Holy Scriptures condemning homosexual activities and behaviours. MoWC held dialogues with religious persons. Although no-one wanted to stop the exhibition, many were critical of the artist’s mixing of Holiness and Nudity/Sexuality. The Museum was criticized for bending to fundamentalist pressure, assuming that it had plans to stop the exhibition, and a media debate on censorship and freedom of speech followed. This paper analyzes the situatedness of MoWC, and its discursive belonging. How can a state governed institution deal with legitimate and opposing claims, and counter both heteronormativity and islamophobia? What discourses is the Museum institution inscribed in? What power relations follow from that? Is it, due to historic, bureaucratic, and cultural legacies, tied to certain positions and affiliations in the public space?

Biofuels are (Not the Future! Legitimation Strategies of Sustainable Ventures in Complex Institutional Environments

Neil A. Thompson

2018-04-01

Full Text Available Sustainable ventures often lack legitimacy (perceived to be desirable and appropriate because various stakeholder groups use contradictory institutions (rules and norms to make their judgements, which leads to there being fewer resources available and higher failure rates. Using an institutional theory framework and a multi-case research design with 15 biofuel ventures operating in the Netherlands, this study asks how sustainable entrepreneurs attempt to gain legitimacy in these circumstances. Analysis reveals that the entrepreneurs use a combination of rhetorical, reconciliatory and institutional change strategies to obtain legitimacy from different stakeholder groups. These findings further our understanding of sustainable entrepreneurial behavior by revealing how and why different legitimation strategies are used in complex institutional environments.

Full Text Available BACKGROUND Hepatitis B Virus (HBV infection is a major public health problem in India. Hepatitis B can be prevented by hepatitis B vaccine, which is the first anticancer vaccine, because it can prevent a form of liver cancer. The protective antibodies induced by vaccination wane gradually over period of time. The aim of the study is to- 1. Estimate serum levels of anti-HBs in individuals vaccinated with hepatitis B vaccine. 2. Immunisation status of hepatitis B vaccination in individuals. MATERIALS AND METHODS A serological study was carried out from March 2015 to the end of September 2016 aimed at estimating the level of HBsantibody. Total of 330 individuals from healthcare workers, staff and children who have received full course of hepatitis B vaccine were selected for study. In a cross-sectional study, anti-HBs antibody was determined by Enzyme-Linked Immunosorbent Assay (ELISA method. RESULTS Three hundred and thirty individuals were enrolled in the study, out of which, 136 were men and 194 were women. Majority were in the age group 20 to 40 years. Anti-HBs antibody titre was more than 100 IU/L in 74% individuals. Titre was between 10 IU/L-100 IU/L in 16% individuals. Anti-HBs titre was less than 10 IU/L in 10% individuals. There was a significant decline in the levels of antibody overtime post vaccination. Antibody titre was low in individuals with diabetes mellitus. Low antibody titre was noted in smokers. CONCLUSION In this study, majority had desirable immune response to the HBV vaccine. Diabetes mellitus, long duration post vaccination and positive smoking history have attributed to low anti-HBs titre in subjects who had inadequate levels in our study. As immunological memory persists for long time even in the absence of significant titre of anti-HBs, booster dose vaccination is routinely not advocated for general population. But, healthcare professionals are advised to receive booster dose vaccination at 5 years if anti-HBs value is

The introduction of anti-vascular endothelial growth factor (anti-VEGF) drugs to ophthalmology has revolutionized the treatment of neovascular age-related macular degeneration (nAMD). Despite this significant progress, gaps and challenges persist in the diagnosis of nAMD, initiation of treatment, and management of frequent intravitreal injections. Thus, nAMD remains a leading cause of blindness in the United States. To present current knowledge, evidence, and expert perspectives on anti-VEGF therapies in nAMD to support managed care professionals and providers in decision making and collaborative strategies to overcome barriers to optimize anti-VEGF treatment outcomes among nAMD patients. Three anti-VEGF therapies currently form the mainstay of treatment for nAMD, including 2 therapies approved by the FDA for treatment of nAMD (aflibercept and ranibizumab) and 1 therapy approved by the FDA for oncology indications and used off-label for treatment of nAMD (bevacizumab). In clinical trials, each of the 3 agents maintained visual acuity (VA) in approximately 90% or more of nAMD patients over 2 years. However, in long-term and real-world settings, significant gaps and challenges in diagnosis, treatment, and management pose barriers to achieving optimal outcomes for patients with nAMD. Many considerations, including individual patient characteristics, on-label versus off-label treatment, repackaging, and financial considerations, add to the complexity of nAMD decision making and management. Many factors may contribute to additional challenges leading to suboptimal long-term outcomes among nAMD patients, such as delays in diagnosis and/or treatment approval and initiation, individual patient response to different anti-VEGF therapies, lapses in physician regimentation of anti-VEGF injection and monitoring, and inadequate patient adherence to treatment and monitoring. These latter factors highlight the considerable logistical, emotional, and financial burdens of long

Considering that the main route of Mycobacterium leprae transmission is the upper respiratory tract, detection of salivary antibodies can be a useful tool for diagnosing early infection. The study aimed to analyze salivary anti-PGL-1 IgA and IgM antibodies in 169 children aged 4-16 years old, who lived nearby or inside the house of multibacillary or paucibacillary leprosy patients in two endemic cities in Alagoas State - Brazil. Salivary anti-PGL-1 antibodies were quantified by modified ELISA method. The frequency of contact and clinical form of the index case were significantly associated with salivary antibody levels. High frequency of IgM positivity strongly suggests active transmission of M. leprae in these communities. We suggest in the present work that salivary anti-PGL IgA and IgM are important biomarkers to be used for identifying communities with probable active transmission of M. leprae.

2017-08-15

Background: Roasted seeds of Amazonian guarana ( Paullinia cupana var. sorbilis; Sapindaceae) are popular in South America due to their stimulant activity on the central nervous system (CNS). Rich in purine alkaloids, markedly caffeine, the seeds are extensively used in the Brazilian beverage industry for the preparation of soft drinks and as additives in energy drinks. Methods: To investigate the putative anti-aging and antioxidant activity of guarana, we used the model organism Caenorhabditis elegans . Chemical analyses were performed using high-performance liquid chromatography (HPLC) and electrospray ionization-mass spectrometry (ESI-MS/MS). Results: When tested in the model system Caenorhabditis elegans , the water extract from roasted guarana seeds enhanced resistance against oxidative stress, extended lifespan and attenuated aging markers such as muscle function decline and polyQ40 aggregation. Conclusions: In the current study, we demonstrate that guarana extracts can work as a powerful antioxidant in vivo; moreover, guarana extracts exhibit anti-aging properties. Our results suggest that the biological activities of guarana go beyond the extensively reported CNS stimulation.

Does the Sole Description of a Tax Authority Affect Tax Evasion? - The Impact of Described Coercive and Legitimate Power

Following the classic economic model of tax evasion, taxpayers base their tax decisions on economic determinants, like fine rate and audit probability. Empirical findings on the relationship between economic key determinants and tax evasion are inconsistent and suggest that taxpayers may rather rely on their beliefs about tax authority’s power. Descriptions of the tax authority’s power may affect taxpayers’ beliefs and as such tax evasion. Experiment 1 investigates the impact of fines and beliefs regarding tax authority’s power on tax evasion. Experiments 2-4 are conducted to examine the effect of varying descriptions about a tax authority’s power on participants’ beliefs and respective tax evasion. It is investigated whether tax evasion is influenced by the description of an authority wielding coercive power (Experiment 2), legitimate power (Experiment 3), and coercive and legitimate power combined (Experiment 4). Further, it is examined whether a contrast of the description of power (low to high power; high to low power) impacts tax evasion (Experiments 2-4). Results show that the amount of fine does not impact tax payments, whereas participants’ beliefs regarding tax authority’s power significantly shape compliance decisions. Descriptions of high coercive power as well as high legitimate power affect beliefs about tax authority’s power and positively impact tax honesty. This effect still holds if both qualities of power are applied simultaneously. The contrast of descriptions has little impact on tax evasion. The current study indicates that descriptions of the tax authority, e.g., in information brochures and media reports, have more influence on beliefs and tax payments than information on fine rates. Methodically, these considerations become particularly important when descriptions or vignettes are used besides objective information. PMID:25923770

Gender is known to be associated with longevity and oestrogen administration induced longevity-associated gene expression is one of the potential mechanisms underlying the benefits of oestrogen on lifespan, whereas the role of testosterone in the regulation of longevity-associated gene expressions remains largely unclear. The klotho gene, predominantly expressed in the kidney, has recently been discovered to be an aging suppressor gene. In the present study, we investigated the regulatory effects of testosterone on renal klotho gene expression in vivo and in vitro. In testosterone-administered mouse kidney and NRK-52E cells, increased klotho expression was accompanied by the up-regulation of the nuclear androgen receptor (AR). Overexpression of AR enhanced the expression of klotho mRNA and protein. Conversely, testosterone-induced klotho expression was attenuated in the presence of flutamide, an AR antagonist. A reporter assay and a chromatin immunoprecipitation (ChIP) assay demonstrated that AR directly binds to the klotho promoter via androgen response elements (AREs) which reconfirmed its importance for AR binding via the element mutation. In summary, our study demonstrates that testosterone up-regulates anti-aging klotho together with AR expression in the kidney in vivo and in vitro by recruiting AR on to the AREs of the klotho promoter.

Unal, E; Gokler, M E; Metintas, S; Kalyoncu, C

2016-12-12

The aim of the present study was to determine the perception of 10 anti-smoking advertisements in 1434 Turkish adolescents. We used the Effectiveness of the Anti-smoking Advertisements Scale, which included 6 items for each advertisement; each item was assessed on a 5-point Likert-type scale. Multiple logistic regression analysis was used to determine the factors associated with the impact of the advertisements. All the advertisements were more effective for adolescents who had never smoked compared to ex-smokers and current smokers. We also noted that, regardless of age, smoking status decreased the effectiveness of all the advertisements. Previous studies have shown that smokers have a negative attitude towards anti-smoking messages. In the present study, the most effective advertisements among adolescents were those with "Sponge and tar", "Smoking harms in every breath" and "Children want to grow". In conclusion, although anti-smoking campaigns are targeted towards adults, they also have a strong influence on adolescents. The main target population for advertisements should be individuals aged < 15 years who have not yet started smoking.

Sulphated polysaccharides with anti-thrombotic and anti-coagulant activities have been found in various marine biota. In this study, a previously characterised anti-thrombotic and anti-coagulant extract from blacklip abalone was fractionated by anion exchange chromatography (AEC), pooled (on a sulphated polysaccharide basis) and administered to Wistar rats via oral gavage (N = 8) for assessment as an oral therapeutic. To ensure that the preparation had anti-coagulant activity prior to oral administration, it was assessed in rat blood by thromboelastography (TEG) significantly increasing reaction (R) time (or time until clot formation). Following in vitro confirmation of anti-coagulant activity, 40 mg of the preparation was orally administered to rats with blood samples collected at 2, 4, and 6 h post-gavage. Assessment of all blood samples by TEG showed some prolongation of R time from 355 to 380 s after 4 h. Dosing of the post-gavage blood samples with the abalone preparation to confirm anti-thrombotic activity in vitro revealed residual anti-coagulant activity, further suggesting that oral administration did increase anti-coagulant potential in the collected blood but that bioavailability was low. Assessment of tissues and haematological parameters showed no obvious harmful effects of the abalone preparation in animals. In summary, even though oral administration of fractionated and pooled blacklip abalone extract to rats delayed clotting after 4 h, bioavailability of the preparation appeared to be low and may be more appropriate for intravenous administration as an anti-thrombotic or anti-coagulant therapeutic.

To determine whether there is an association between nonencephalitic herpes simplex virus 1 (HSV-1) infection and anti-NMDA receptor encephalitis (anti-NMDARE). Antibody testing was performed using samples from 2 cohorts in a case-control observational study. The cohort "Philadelphia" included 16 serum samples of pediatric anti-NMDARE cases and 42 age-matched controls with other neuroinflammatory disorders studied at the Children's Hospital of Philadelphia and University of Pennsylvania. The cohort "Barcelona" contained 23 anti-NMDARE patient samples and 26 age-matched participants with other neuroinflammatory disorders studied at IDIBAPS-Hospital Clinic, University of Barcelona. The presence of HSV-1 IgG antibodies was examined by ELISA. As an additional control, IgG antibodies to cytomegalovirus (CMV) and Epstein-Barr virus viral capsid antigen (EBV-VCA) were determined. In each cohort, more participants with anti-NMDARE than controls had anti-HSV-1 IgG antibodies. In the Philadelphia cohort (58 participants), 44% of anti-NMDARE cases had antibodies to HSV-1 compared with 14% controls (OR 4.67, 95% CI 1.3-17.3, p = 0.031). In the Barcelona cohort (49 participants), 52% of participants with anti-NMDARE had antibodies to HSV-1 compared with 31% of controls (OR 2.45, 95% CI 0.7-7.9, p = 0.155). Overall, 49% of anti-NMDARE cases have antibodies to HSV-1 in these 2 combined cohorts compared with 21% of controls (Mantel-Haenszel OR 3.21, 95% CI 1.3-7.7, p = 0.007). Past HSV-1 infection was found in significantly more anti-NMDARE cases than controls. This suggests a meaningful association between nonencephalitic HSV-1 infection and development of anti-NMDARE.

Cronin, Hyland; Draelos, Zoe Diana

2010-09-01

New developments in the realm of skin rejuvenation such as phytotherapy are at an astounding increasing pace in the cosmeceutical market. Yet, many of these products that are classified as cosmeceuticals are tested less vigorously and do not have to be approved by the Food and Drug Administration to establish efficacy and safety. Thus, as clinicians, we must ask the question, "Is there science-based evidence to validate the mechanism of these new treatments?" We assessed the top anti-aging creams currently on the market specifically evaluating their botanical ingredients. Some of the most common botanicals that are hot off the market are: Rosmarinus officinalis, Vitis vinifera (grape seed extract), Citronellol, Limonene, Oenothera biennis (evening primrose), Glycyrrhiza glabra (licorice extract), Aframomum angustifolium seed extract, Diosgenin (wild yam), N6 furfuryladenine (kinetin), and Ergothioneine. Through researching each of these botanical ingredients, we have concluded that randomized controlled trials are still needed in this area, but there is promise in some of these ingredients and science to validate them. © 2010 Wiley Periodicals, Inc.

To determine single year age-specific anti-Müllerian hormone (AMH) standard deviation scores (SDS) for women associated to normal ovarian function and different ovarian disorders resulting in sub- or infertility. Determination of particular year median and mean AMH values with standard deviations (SD), calculation of age-independent cut off SDS for the discrimination between normal ovarian function and ovarian disorders. Single-year-specific median, mean, and SD values have been evaluated for the Beckman Access AMH immunoassay. While the decrease of both median and mean AMH values is strongly correlated with increasing age, calculated SDS values have been shown to be age independent with the differentiation between normal ovarian function measured as occurred ovulation with sufficient luteal activity compared with hyperandrogenemic cycle disorders or anovulation associated with high AMH values and reduced ovarian activity or insufficiency associated with low AMH, respectively. These results will be helpful for the treatment of patients and the ventilation of the different reproductive options. Copyright © 2017 Elsevier B.V. All rights reserved.

Anti-Inflamm-Ageing and/or Anti-Age-Related Disease Emerging Treatments: A Historical Alchemy or Revolutionary Effective Procedures?

Full Text Available The “long-life elixir” has long represented for humans a dream, a vanity’s sin for remaining young and to long survive. Today, because of ageing population phenomenon, the research of antiageing interventions appears to be more important than ever, for preserving health in old age and retarding/or delaying the onset of age-related diseases. A hope is given by experimental data, which evidence the possibility of retarding ageing in animal models. In addition, it has been also demonstrated in animal life-extending studies not only the possibility of increasing longevity but also the ability to retard the onset of age-related diseases. Interestingly, this recent evidence is leading to promise of obtaining the same effects in humans and resulting in benefits for their health in old ages. In order to achieve this goal, different approaches have been used ranging from pharmacological targeting of ageing, basic biological assays, and big data analysis to the recent use of young blood, stem cells, cellular, genetic, and epigenetic reprogramming, or other techniques of regenerative medicine. However, only a little fraction of these approaches has the features for being tested in clinical applications. Here, new emerging molecules, drugs, and procedures will be described, by evidencing potential benefits and limitations.

Oncocalyxone A functions as an anti-glycation agent in vitro.

Directory of Open Access Journals (Sweden)

Ingrid Sofia Vieira de Melo

Full Text Available Advanced glycation endproducts (AGE are the result of post-translational changes to proteins, which ultimately compromise their structure and/or function. The identification of methods to prevent the formation of these compounds holds great promise in the development of alternative therapies for diseases such as diabetes. Plants used in traditional medicine are often rich sources of anti-glycation agents. Therefore, in this study, we investigated the anti-glycation activity of one such compound, Oncocalyxone A (Onco A. Using spectrofluorimetric techniques, we determined that Onco A inhibits AGE formation in a concentration-dependent manner. Its IC50 value (87.88 ± 3.08 μM was almost two times lower than the standard anti-glycation compound aminoguanidine (184.68 ± 4.85 μM. The excellent anti-glycation activity of Onco A makes it an exciting candidate for the treatment of diseases associated with excessive accumulation of AGE. However, additional studies are necessary to identify its mechanism of action, as well as the in vivo response in suitable model organisms.

Safety assessment was performed in all patients. Anti-D caused a quicker response on the 3rd day of treatment (P anti-D had lower rate of side effects including fever (P anti-D was associated with rapid rise of platelets compared to IVIG. In addition, anti-D treatment had acceptable safety profile. © 2016 Société Française de Pharmacologie et de Thérapeutique.

A tainted trade? Moral ambivalence and legitimation work in the private security industry.

Thumala, Angélica; Goold, Benjamin; Loader, Ian

2011-06-01

The private security industry is often represented - and typically represents itself - as an expanding business, confident of its place in the world and sure of its ability to meet a rising demand for security. But closer inspection of the ways in which industry players talk about its past, present and future suggests that this self-promotion is accompanied by unease about the industry's condition and legitimacy. In this paper, we analyse the self-understandings of those who sell security - as revealed in interviews conducted with key industry players and in a range of trade materials - in order to highlight and dissect the constitutive elements of this ambivalence. This analysis begins by describing the reputational problems that are currently thought to beset the industry and the underlying fears about its status and worth that these difficulties disclose. We then examine how security players seek to legitimate the industry using various narratives of professionalization. Four such narratives are identified - regulation, education, association and borrowing - each of which seeks to justify private security and enhance the industry's social worth. What is striking about these legitimation claims is that they tend not to justify the selling of security in market terms. In conclusion we ask why this is the case and argue that market justifications are 'closed-off' by a moral ambivalence that attaches to an industry trading in products which cannot guarantee to deliver the condition that its consumers crave. © London School of Economics and Political Science 2011.

2016-12-01

Full Text Available We defend the importance of studying the discriminatory treatment of criminal law from the analysis of discourses on the subjectivities, resulting in dichotomy citizen/enemy. Rationalisations about the category of enemy in so-called "law of risk", seem to justify the unequal exercise of power punitive and the neutralization of individuals labelled as harmful and abnormal behavior, even if this is at the expense of principles, fundamental rights and guarantees of the rule of law. Such discourses also favors the neoliberal environment, to the extent that translate the entire conflitividade on punishment and legitimized stigmatization processes, criminalization of poverty and criminal selectivity.

Full Text Available Background & objectives: Several autoimmune disorders have been reported to be associated with autoimmune thyroiditis and may coexist with other organ-specific autoantibodies. The aim of the present study was to evaluate the presence of tissue transglutaminase (anti-TTG and glutamic acid decarboxylase (anti-GAD antibodies in patients suffering from autoimmune thyroiditis as diagnosed by anti-thyroid peroxidase (anti-TPO antibodies, which may indicate high risk for developing celiac disease or type 1 diabetes mellitus. Methods: Five thousand children and 2800 adults were screening as part of a general health examination done on a voluntary basis in four different parts of Delhi. A total of 577 subjects positive for anti-TPO antibody constituted the cases. Equal number of age and sex matched anti-TPO antibody negative controls were randomly selected from the same cohort to form paired case control study. The cases and controls were further divided into two groups as follows: group-1 (children and adolescent 18 yr. Serum samples of cases and controls were analysed for thyroid function test (FT3, FT4, and TSH, anti-TTG and anti-GAD antibodies. Results: A total of 1154 subjects (577 cases and 577 controls were included in this study. Hypothyroidism was present in 40.2 per cent (232 cases compared to only 4.7 per cent (27 in controls (P<0.001. Anti-TTG and anti-GAD antibodies were present in 6.9 and 12.5 per cent subjects among cases compared to 3.5 per cent (P=0.015 and 4.3 per cent (P=0.001 in controls, respectively. Only anti-GAD antibody were significantly positive in cases among children and adolescents (P =0.0044 and adult (P=0.001 compared to controls. Levels of anti-TTG and anti-GAD antibodies increased with increasing titre of anti-TPO antibody. Interpretation & conclusions: Our findings showed high positivity of anti-GAD and anti-TTG antibodies among subjects with thyroid autoimmunity. It is, therefore, important to have high clinical index

How useful is determination of anti-factor Xa activity to guide bridging therapy with enoxaparin? A pilot study.

2009-02-01

Low-molecular-weight heparins (LMWH) are commonly used as peri-procedural bridging anticoagulants. The usefulness of measurement of anti-factor Xa activity (anti-Xa) to guide bridging therapy with LMWH is unknown. It was the objective of this study to determine levels of anti-Xa during standard bridging therapy with enoxaparin, and to examine predictors for residual anti-Xa. Consecutive patients receiving enoxaparin at a dosage of 1 mg/kg body weight/12 hours for temporary interruption of phenprocoumon were prospectively enrolled to the study. Blood-samples were obtained 14 hours after LMWH-application immediately pre- procedurally. Procedural details, clinical and demographic data were collected and subsequently analyzed. Seventy patients were included (age 75.2 +/- 10.8 years, Cr Cl 55.7 +/- 21.7ml/min, body mass index [BMI] 27.1 +/- 4.9). LMWH- therapy was for a mean of 4.2 +/- 1.6 days; overall anti-Xa was 0.58 +/- 0.32 U/ml. In 37 (52.8%) of patients anti-Xa was > or U/ml, including 10 (14.3%) patients with anti-Xa > 1U/ml. Linear regression analysis of single variables and logistic multivariable regression analysis failed to prove a correlation between anti-Xa and single or combined factors. No major bleeding, no thromboembolism and four (5.7%) minor haemorrhages were observed. When bridging OAC with therapeutic doses of enoxaparin a high percentage of patients undergo interventions with high residual anti-Xa. The levels of anti-Xa vary largely and are independent of single or combined clinical variables. Since the anti-Xa-related outcome of patients receiving bridging therapy with LMWH is not investigated, no firm recommendation on the usefulness of monitoring of anti-Xa can be given at this stage.

2010-02-01

A wide variety of radio frequency (RF) treatments for localized fat and cellulite reduction as well as anti-aging are available nowadays, but only a few have shown the biological mechanism responsible for the clinical results. To determine the biological mechanism of the TriPollar RF device for localized fat and cellulite reduction as well as the collagen remodeling effect. Human skin samples were collected from abdominoplasty surgery and facial lifts, in order to evaluate the lipolytic and anti-aging effects of the apollo device powered by TriPollar RF technology using an ex vivo human skin model. The anti-cellulite effect was evaluated by the dosage of released glycerol and histological analysis of the hypodermis. Skin tightening was evaluated by morphometric analysis of collagen fibers and the dosage of collagen synthesis. Following TriPollar treatment, a significant increase of glycerol release by skin samples was found. The structure of fat cells was altered in shape and a modification of the fibrous tract was also detected in the fat layer. Additional findings indicated stimulation of the dermal fibroblasts with increased collagen synthesis. The detected alteration in the hypodermal layer is manifested by fat and cellulite reduction accompanied by structural and biochemical improvement of dermal collagen, which result in overall skin tightening.

Full Text Available Fair and equitable standard of treatment of foreign investments represents an integral part of all modern international agreements on protection and encouragement of foreign investments. The key element of its contents, according to arbitral practice, is an obligation of the host state to provide the investor with the treatment in accordance with basic expectations that he or she had at the time of the investment with regard to economical and legal conditions in the host state. The paper analyzes the most important awards of arbitral tribunals dealing with legitimate expectations of the investor as a part of the fair and equitable treatment standard. A considerable attention is dedicated to identifying the behavior of the host state capable of creating legitimate expectation which enjoy legal protection as well as to detecting the requirements for the development of reasonable expectations.

Objective: The objective of this study was to compare the frequency of anti thyroid peroxidase antibody in patients suffering from vitiligo with healthy control group. Type of Study: Case control study. Settings: Dermatology Department, Military Hospital, Rawalpindi, from 20th March 2010 to 20th July 2011. Material and Methods: Fifty clinically diagnosed patients of vitiligo, age = 18 yrs and both genders with no history of thyroid disease, past or current use of drugs for thyroid disorder or thyroid surgery were included as cases (Group A). Fifty healthy individuals with no evidence of vitiligo or thyroid disorder on history and physical examination and with no family history of vitiligo, matched for age and gender with cases, were included as control (Group B). Serum anti thyroid peroxidase (anti TPO) antibodies were measured using enzyme linked immunosorbent assay (ELISA) in both cases and control. Results: Eight (16%) patients in Group A were anti-thyroid peroxidase antibody positive and forty two (84%) patients were negative while one (2%) patient was anti-thyroid peroxidase antibody positive in Group B and forty nine (98%) patients were negative (p = 0.001). Conclusion: Anti TPO antibody is significantly more common in patients of vitiligo as compared to general population. (author)

Full Text Available Autism spectrum disorders (ASD are characterized by impairments in communication, social interactions, and repetitive behaviors. While the etiology of ASD is complex and likely involves the interplay of genetic and environmental factors, growing evidence suggests that immune dysfunction and the presence of autoimmune responses including autoantibodies may play a role in ASD. Anti-phospholipid antibodies are believed to occur from both genetic and environmental factors and have been linked to a number of neuropsychiatric symptoms such as cognitive impairments, anxiety, and repetitive behaviors. In the current study, we investigated whether there were elevated levels of anti-phospholipid antibodies in a cross-sectional analysis of plasma of young children with ASD compared to age-matched typically developing (TD controls and children with developmental delays (DD other than ASD. We found that levels of anti-cardiolipin, β2-glycoprotein 1, and anti-phosphoserine antibodies were elevated in children with ASD compared with age-matched TD and DD controls. Further, the increase in antibody levels was associated with more impaired behaviors reported by parents. This study provides the first evidence for elevated production of anti-phospholipid antibodies in young children with ASD and provides a unique avenue for future research into determining possible pathogenic mechanisms that may underlie some cases of ASD.

A 615+-12 m.y. age is obtained by U-Pb method on zircons extracted from the granodiorite of Bleida (Anti-Atlas, Morocco). This age which is in good agreement with U-Pb and Rb-Sr previous data, argues for the occurrence of the panafrican orogeny in the Anti-Atlas and contributes to define the chronology of the typical features of this orogenic belt [fr

Anti-glomerular basement membrane (GBM) disease is a rare autoantibody-mediated disorder presenting as rapidly progressive glomerulonephritis, and often with pulmonary hemorrhage. Antibody removal with plasmapheresis and immunosuppressive drugs are the cornerstones of the treatment. Data regarding the use of specific B-cell depleting therapy such as rituximab are lacking. We conducted a retrospective observational study of 8 patients with severe and/or refractory GBM disease that received rituximab therapy. Eight patients (2 men, 6 women) with a mean age of 26 ± 13.1 years old were included. Seven had severe renal involvement [median creatinin level was 282 μmol/l, range (65-423)] requiring high immunosuppressive or plasmapheresis dependent, and two had relapse of pulmonary hemorrhage including one with renal failure. Patients received an initial immunosuppressive treatment including steroid and cyclosphosphamide (n = 8) and plasmapheresis (n = 5). Except one late relapse, rituximab therapy was started within two months after diagnosis. All patients except one received 4 weekly dose of rituximab (375 mg(2)). Anti-GBM antibodies were still present in 6/8 patients, at rituximab initiation. Complete remission was observed in 7 out of 8 patients, mostly 3 months after rituximab therapy. After a mean follow-up of 25.6 months (range 4-93), patient and renal survival were 100% and 75% respectively, but rituximab use did not improve GFR. Anti-GBM antibodies remained negative for all patients during follow-up. Only one patient developed a severe bacterial infection but no opportunistic or viral infections were reported. Rituximab may represent an additional and/or alternative therapy in the induction treatment of anti-GBM disease. Copyright © 2015 Elsevier Ltd. All rights reserved.

Theatrical language, narrative techniques and anti-anti-Gypsyism

Full Text Available With this article based on his fieldwork in Šuto Orizari, a Municipality in the suburbs of Skopje (Macedonia, the author analyses how theatrical language and narrative techniques can be used to oppose the strengthening of anti-gypsyism in public opinion. Šuto Orizari is the only Municipality in the world where romanés is used as an official language, and the Mayor and the majority of the members of the assembly of the municipality come from the Roma community, thus enjoying a degree of effective self-government. Andrea Mochi Sismondi and Fiorenza Menni lived there for two years trying to understand the different visions of the world originating among Roma, while collecting dramaturgical materials later used in the production of two theatrical performances, a book and several public events where Roma and Gadžé can exchange their points of view on fundamental issues concerning political philosophy. Freedom, equality, the legitimate aspiration to a better life, freedom of movement: all values modern constitutions are based on, and on which the two artists focused their long interviews and conversations with Šuto Orizari citizens and Roma colleagues. The work has been presented all over Italy and its results reveal how literary non-fiction and performing arts can be successfully used to show the weakness of the arguments alleging the cultural distance that would make the dialogue between Roma and Gadžé impossible.

The interpretation of methamphetamine and amphetamine positive test results in biological samples is a challenge to clinical and forensic toxicology for several reasons. The effects of pH and dilution of urine samples and the knowledge about legitimate and illicit sources have to be taken into account. Besides a potentially legal prescription of amphetamines, many substances metabolize to methamphetamine or amphetamine in the body: amphetaminil, benzphetamine, clobenzorex, deprenyl, dimethylamphetamine, ethylamphetamine, famprofazone, fencamine, fenethylline, fenproporex, furfenorex, mefenorex, mesocarb, and prenylamine. Especially the knowledge of potential origins of methamphetamine and amphetamine turns out to be very important to prevent a misinterpretation of the surrounding circumstances and to prove illegal drug abuse. In this review, potential precursor compounds are described, including their medical use and major clinical effects and their metabolic profiles, as well as some clues which help to identify the sources.

Full Text Available Since the beginning of research on human trafficking, there has been attention paid to the challenges surrounding the illicit economy. In creating new strategies and initiatives on combatting human trafficking, there needs to be more discussion surrounding the legitimate economy and how the business sector can make an impact in the fight against trafficking. Currently, there is a growing movement of businesses that are looking to address human trafficking through training, education, and leadership initiatives; codes of conduct; supply chain management; and financial analysis. This paper will examine the latest in these strategies and approaches by businesses in the global war against human trafficking, in addition to a discussion of a new initiative engaging the private sector co-led by Dr. Louise Shelley and Christina Bain through the World Economic Forum’s Global Agenda Council Network.

Hepatitis B virus (HBV) infection is highly endemic (7-8% prevalence) in rural China, causing high mortality and societal burden. Data from men of reproductive age is scarce and last reported in 2006. We assessed the seroepidemiology of men in rural China, aiming to provide updated baseline data for the prevalence of HBV infection. We established prevalence of HBV infection from data gathered through a nationwide population-based study of Chinese rural men aged 21-49 years. Data were obtained from a physical check-up programme for couples of reproductive age, the National Free Preconception Health Examination Project, that covered 31 provinces from 2010-12. We tested serological samples with ELISA and categorised participants' HBV status based on presence of HBsAg, anti-HBV core antibody (anti-HBc), and anti-HBV surface antibody (anti-HBs). 2 030 083 men were recruited into the database from Jan 1, 2010, to Dec 31, 2012, and 1 966 013 men provided serum samples for analysis. 124 274 men (6%) tested positive for HBsAg, 178 559 (9%) tested positive for anti-HBc, and 583 923 (30%) tested positive for anti-HBs. Isolated anti-HBs (an indicator of vaccine-mediated immunity) were present in 527 566 men (27%). And 1 234 127 men (63%) were negative for all HBV makers (susceptible population). HBsAg prevalence was higher in men aged 25-39 years (6·35-6·47%) than in other age groups (5·54-5·78%; pChina than in the central or western regions (all pChina has changed from highly endemic into intermediate endemic in the past two decades. However, the absolute number of HBV-infected men and the susceptible population is still very large. Chinese Association of Maternal and Child Health Studies. Copyright © 2016 Elsevier Ltd.

Anti-lactoferrin antibodies (ALA) and anti-myeloperoxidase antibodies (AMPA) are specific serological markers for autoimmune hepatitis (AIH). The project aimed to detect ALA and AMPA and explore their clinical significances in AIH patients. 59 AIH patients, 217 non AIH patients, and 50 healthy controls were enrolled in this study. ALA and AMPA were detected by ELISA. Antineutropil cytoplasmic antibodies (ANCA) and anti-smooth muscle antibodies (ASMA) were examined by indirect immunofluorescence. Antimitochondrial antibody M2 subtype (AMA-M2), anti-liver kidney microsomal antibody Type 1 (LKM1), anti-liver cytosol antibody Type 1 (LC1), and anti-soluble liver antigen/liver-pancreas antibodies (SLA/LP) were tested by immunoblot. The positivity for ALA was 18.6% in AIH group, only one patient in non-AIH group was positive for ALA; the positivity for AMPA was 59.3% in AIH group, with significant differences (P < 0.01) compared with other groups. The specificities for ALA and AMPA were 99.63% and 97.75%; the sensitivities were 18.64% and 59.32%; and the accuracy rates were 84.97% and 90.80%, respectively. A certain correlation was observed between ALA and SLA/LP, AMPA and ANCA, ASMA in AIH group. ALA and AMPA were associated with AIH, and had high clinical diagnostic value. Co-detection with other relative autoantibodies could play an important role in differential diagnosis of AIH.

The formation of macular hole after receiving anti-vascular endothelial growth factor (anti-VEGF) therapy is rare. We report a case of macular hole that occurred after intravitreal injection of an anti-VEGF agent for age-related macular degeneration (AMD) in a patient, who underwent vitrectomy combined with choroidal neovascularization (CNV) removal. A 64-year-old female with AMD affecting her right eye received an intravitreal injection of an anti-VEGF agent. After treatment, we identified a full thickness macular hole (MH) that was associated with the rapid resolution of the macular edema and contraction of the CNV. After performing vitrectomy combined with CNV removal, the MH closed and her visual acuity improved. Examination of the removed CNV revealed a network of microvessels devoid of pericytes. and Importance: The present findings suggest that rapid resolution of macular edema and contraction of the CNV and/or mild increase in the vitreous traction after anti-VEGF therapy could potentially cause MH. CNV removal via the MH may be an acceptable procedure, if the MH remains open, the CNV is of the classic type, and it spares a central portion of the fovea.

To describe the changes of fundus autofluorescence (FAF) in patients with age-related macular degeneration before and after intravitreal injection of anti-vascular endothelial growth factor according to the type of choroidal neovascularization (CNV) and to evaluate the correlation of FAF with spectral domain optical coherence tomography (SD-OCT) parameters and vision. This was a retrospective study. Twenty-one treatment-naïve patients with neovascular age-related macular degeneration were included. Study eyes were divided into two groups according to the type of CNV. Fourteen eyes were type 1 CNV and seven eyes were type 2 CNV. All eyes underwent a complete ophthalmologic examination, including an assessment of best-corrected visual acuity, SD-OCT, fluorescein angiography, and FAF imaging, before and 3 months after intravitreal anti-vascular endothelial growth factor injection. Gray scales of FAF image for CNV areas, delineated as in fluorescein angiography, were analyzed using the ImageJ program, which were adjusted by comparison with normal background areas. Correlation of changes in FAF with changes in SD-OCT parameters, including CNV thickness, photoreceptor inner and outer segment junction disruption length, external limiting membrane disruption length, central macular thickness, subretinal fluid, and intraretinal fluid were analyzed. Eyes with both type 1 and type 2 CNV showed reduced FAF before treatment. The mean gray scales (%) of type 1 and type 2 CNV were 52.20% and 42.55%, respectively. The background values were 106.72 and 96.86. After treatment, the mean gray scales (%) of type 1 CNV and type 2 CNV were changed to 57.61% (p = 0.005) and 57.93% (p = 0.008), respectively. After treatment, CNV thickness, central macular thickness, and inner and outer segment junction disruption length were decreased while FAF increased. FAF was noted to be reduced in eyes with newly diagnosed wet age-related macular degeneration, but increased after anti

Full Text Available Abstract Background Several factors contribute to the deterioration in synaptic plasticity which accompanies age and one of these is neuroinflammation. This is characterized by increased microglial activation associated with increased production of proinflammatory cytokines like interleukin-1β (IL-1β. In aged rats these neuroinflammatory changes are associated with a decreased ability of animals to sustain long-term potentiation (LTP in the dentate gyrus. Importantly, treatment of aged rats with agents which possess anti-inflammatory properties to decrease microglial activation, improves LTP. It is known that endocannabinoids, such as anandamide (AEA, have anti-inflammatory properties and therefore have the potential to decrease the age-related microglial activation. However, endocannabinoids are extremely labile and are hydrolyzed quickly after production. Here we investigated the possibility that inhibiting the degradation of endocannabinoids with the fatty acid amide hydrolase (FAAH inhibitor, URB597, could ameliorate age-related increases in microglial activation and the associated decrease in LTP. Methods Young and aged rats received subcutaneous injections of the FAAH inhibitor URB597 every second day and controls which received subcutaneous injections of 30% DMSO-saline every second day for 28 days. Long-term potentiation was recorded on day 28 and the animals were sacrificed. Brain tissue was analyzed for markers of microglial activation by PCR and for levels of endocannabinoids by liquid chromatography coupled to tandem mass spectrometry. Results The data indicate that expression of markers of microglial activation, MHCII, and CD68 mRNA, were increased in the hippocampus of aged, compared with young, rats and that these changes were associated with increased expression of the proinflammatory cytokines interleukin (IL-1β and tumor necrosis factor-α (TNFα which were attenuated by treatment with URB597. Coupled with these changes, we

Although a major risk factor for Alzheimer's disease (AD), the "aging" parameter is not systematically considered in preclinical validation of anti-AD drugs. To explore how aging affects neuronal reactivity to anti-AD agents, the ciliary neurotrophic factor (CNTF)-associated pathway was chosen as a model. Comparison of the neuroprotective properties of CNTF in 6- and 18-month old mice revealed that CNTF resistance in the older animals is associated with the exclusion of the CNTF-receptor subunits from rafts and their subsequent dispersion to non-raft cortical membrane domains. This age-dependent membrane remodeling prevented both the formation of active CNTF-receptor complexes and the activation of prosurvival STAT3 and ERK1/2 pathways, demonstrating that age-altered membranes impaired the reactivity of potential therapeutic targets. CNTF-receptor distribution and CNTF signaling responses were improved in older mice receiving dietary docosahexaenoic acid, with CNTF-receptor functionality being similar to those of younger mice, pointing toward dietary intervention as a promising adjuvant strategy to maintain functional neuronal membranes, thus allowing the associated receptors to respond appropriately to anti-AD agents.

Are Smart People Less Racist? Verbal Ability, Anti-Black Prejudice, and the Principle-Policy Paradox

2016-01-01

It is commonly hypothesized that higher cognitive abilities promote racial tolerance and a greater commitment to racial equality, but an alternative theoretical framework contends that higher cognitive abilities merely enable members of a dominant racial group to articulate a more refined legitimizing ideology for racial inequality. According to this perspective, ideological refinement occurs in response to shifting patterns of racial conflict and is characterized by rejection of overt prejudice, superficial support for racial equality in principle, and opposition to policies that challenge the dominant group's status. This study estimates the impact of verbal ability on a comprehensive set of racial attitudes, including anti-black prejudice, views about black-white equality in principle, and racial policy support. It also investigates cohort differences in the effects of verbal ability on these attitudes. Results suggest that high-ability whites are less likely than low-ability whites to report prejudicial attitudes and more likely to support racial equality in principle. Despite these liberalizing effects, high-ability whites are no more likely to support a variety of remedial policies for racial inequality. Results also suggest that the ostensibly liberalizing effects of verbal ability on anti-black prejudice and views about racial equality in principle emerged slowly over time, consistent with ideological refinement theory.

The invariance of the standard model under CPT transformations leads to the equality of particle and antiparticle masses. The recent measurements performed by the CMS experiment on the top anti-top mass difference are a test of such symmetry. In this work non-perturbative QCD effects, which may eventually lead to an apparent difference in the mass of a top and anti-top quark, are studied.

The aim of our study was to share our experience with anti-vascular endothelial growth factor (anti-VEGF) injections in the treatment of neovascular age-related macular degeneration (nAMD) in a real-world setting. A retrospective, observational study. Patients of Indian origin with nAMD receiving anti-VEGF with a minimum follow-up of 12 months were enrolled in this study. In group 1, patients were treated on a pro re nata (PRN) basis; in group 2, patients received a loading dose (3 injecti Results: Overall, we observed that 77.31% (92/119 eyes) of patients either maintained or had improved visual acuity at 12 months' follow-up. Similar visual outcome was observed in both groups. The average number of injections given in group 1 was 4.98 and in group 2 was 3.7. CDVA at 12 months was significantly correlated with type of drug molecule, CSFT at 3 and 12 months, baseline visual acuity, and CDVA at 3 months. PRN treatment with significantly fewer injections achieved similar anatomical and functional outcomes when compared with the loading dose group. The results of this study need to be validated with a larger study group and a longer follow-up. Copyright 2017 Asia-Pacific Academy of Ophthalmology.

Full Text Available Aims: To report a case of wet age-related macular degeneration (wet-AMD refractory to intravitreal anti-vascular endothelial growth factor (anti-VEGF therapy in a patient who showed visual and anatomical improvement and stabilization after starting a subcutaneous treatment course with adalimumab, an anti-tumor necrosis factor-alpha (TNF-α drug, for concomitant Crohn's disease. Methods: Observational case report of a female patient. Ophthalmological evaluation was performed by slit lamp and ophthalmoscopy (posterior pole and anterior segment. Best-corrected visual acuity (BCVA was determined, and imaging was performed by fluorescein angiography, indocyanine green angiography, and optical coherence tomography (OCT. Intravitreal therapies used and treatment with anti-TNF-α were recorded. Results: A 64-year-old woman with wet-AMD was treated with fourteen intravitreal injections of ranibizumab (0.5 mg for a period of 40 months with intervals of 1-6 months. She initially showed a good visual and anatomical response to periodic anti-VEGF treatment but during check visits, anatomical and functional responses deteriorated. At the 40-month follow-up, the patient had developed Crohn's disease, and her rheumatologist started treatment with adalimumab (40 mg subcutaneously every 2 weeks. During the 25 months of treatment with adalimumab, the patient did not require any additional intravitreal anti-VEGF treatments because her BCVA, clinical, and OCT findings improved and remained stable. Conclusions: We described a case of a patient with wet-AMD refractory to anti-VEGF therapy, which clinically benefited from subcutaneous adalimumab therapy. Treatment with subcutaneous anti-TNF-α in combination with anti-VEGF therapy avoids the high cost and risks related to multiple intravitreal anti-VEGF injections with good functional and anatomic outcomes.

We describe a patient who presented with excessive daytime sleepiness (EDS) and was eventually diagnosed with anti-Ma2 encephalitis. Neurological examination disclosed somnolence, left palpebral ptosis, and vertical gaze paresis. A brain MRI showed high signal intensity in the hypothalamus and each hippocampus. Ma2 antibodies were found in the patient's serum, and fiberbronchoscopy disclosed a lung carcinoma. After three months of steroid treatment, the results of the patient's neurological exam became normal. We conclude that anti-Ma2 encephalitis may present with mostly isolated EDS and that it may respond to steroids despite old age and the presence of an untreated lung cancer.

Presence of serum anti-cytomegalovirus (CMV) and anti-parvovirus B19 (HPV-B19) antibodies was studied in 11 women within the first day after consecutive spontaneous abortion in the second trimester of pregnancy and in the control group, consisting of 15 women in the second trimester of a normal pregnancy. Most of studied women manifested presence of serum IgG class anti-CMV antibodies (IgG-anti-CMV) and levels of the antibodies proved significantly higher in women following spontaneous abortions. The patients frequently demonstrated in parallel presence of serum IgG class anti-HPV-B19 antibodies. In one patient a generalised nonimmunological hydrops fetalis was disclosed and her serum contained IgM and IgG class antibodies against CMV as well as against HPV-B19. The results suggest that in majority of the studied women the spontaneous abortion might have resulted from fetal infection due to reactivation of chronic CMV infection in the course of pregnancy.

Xenohormesis in early life: New avenues of research to explore anti-aging strategies through the maternal diet.

de Medina, Philippe

2017-11-01

Aging is a progressive internal physiological deterioration of the organism, leading to the occurrence of age-related lethal diseases. It has become a major societal challenge to understand the processes that drive aging and to develop rational pharmacological agents and dietary approaches to fight against age-related deterioration and diseases. Interestingly, several lines of evidence highlight an influence of the developmental period on the risk of age-related diseases later in life. This field is known as the developmental origins of health and disease. Following this logic, studying the modification of maternal diet during early life may provide innovative new anti-aging approaches. Nutritional and psychological stresses during gestation are associated with poorer offspring health conditions in late life, and must be avoided during pregnancy. Besides these recommendations, very little has been published about the possible use of maternal diet to program offspring for healthy aging and an extended lifespan. Such health benefits may be provided by different foreign molecules, and particularly the phytochemicals produced by stressed plants, or xenohormetins. The xenohormesis hypothesis proposes that xenohormetins are signals of environmental change and trigger a beneficial adaptive response in individuals who consume them. No studies to date have investigated whether the consumption of stressed plants during pregnancy and lactation could provide chemical cues that impact early life programming and thus influence the future health and lifespan of offspring. Investigating the effect of xenohormesis in early life will involve adding edible plants exposed to different stressors (i.e. UV light, heat, ozone, etc.) to maternal diet and the exposure of offspring to this xenohormetin-enriched maternal diet at different periods of their prenatal life. The hypothesis proposed in this article is a potential tool to decipher the possible impact of xenohormesis during early

This was suggested by study of the phylogenetic tree of members of the herpes virus family, which showed a close relationship between VZV (HSV3 and the HSV1 and HSV2 herpes viruses.Methods: The present prospective study was conducted from January 2005 through January 2011. Twenty-four patients afflicted with HSV1 and HSV2 herpes recurrences over a period of years, numbering 6–8 and more recurrences per year, agreed to receive the anti-VZV vaccine. They were compared with 26 nonvaccinated patients presenting with herpes simplex diseases 2–5 times a year. All 50 patients were documented with anti-HSV1, anti-HSV2, and anti-VZV antibody serological testing.Results: From 2005 through 2011, for the 24 anti-VZV vaccinated patients, the average number of herpes relapses decreased to 0, correlated with an increased anti-VZV antibody level and clinical recovery of all patients, whereas no improvement was observed for the 26 nonvaccinated herpes patients.Conclusion: Data for the anti-VZV serological antibody levels tested before and after anti-VZV vaccination showed a significant (P < 0.001 increase among vaccinated patients. This suggests defective anti-VZV immune power in these patients. After 6 years of positive results for anti-VZV vaccine, this is a logical and

We undertook a retrospective observational study using the UK Clinical Practice Research Datalink (CPRD) in the UK between 1990 and 2012 in subjects 50years or older, stratified by age, sex, geographic region and ethnicity. Yearly prescription incidence rates of any AOD and of each specific AOD were calculated as the number of patients first prescribed these AODs per 10,000person-years (py). In women, yearly rates of first prescription of any AOD increased from 1990 to 2006 (from 2.3 to 169.7 per 10,000py), followed by a plateau and a 12% decrease in the last three years. In men, a less steep increase from 1990 to 2007 (from 1.4 to 45.3 per 10,000py) was followed by a plateau from 2008 onwards. Yearly rates of first prescription of any AOD increased up to the age of 85-89years (248.9 per 10,000py in women and 119.3 in men). There were marked differences between ethnic groups and regions. Bisphosphonates were the most frequently prescribed AODs: etidronate till 2000, and then subsequently alendronate. We have demonstrated marked secular changes in rates of anti-osteoporosis drug prescription over the last two decades. The plateau (and decrease amongst women) in rates in recent years, set against an ever ageing population, is worrying, suggesting that the well-documented care gap in osteoporosis treatment persists. The differences in prescription rates by geographic location and ethnicity raise intriguing questions in relation to underlying fracture rates, provision of care and health behaviour. We studied the prescription incidence of anti-osteoporosis drugs (AOD) from 1990 to 2012 in the UK CPRD. Overall AOD prescription incidence showed a strong increase from 1990 to 2006, followed by a plateau in both sexes and a decrease amongst women in the last three years

Research highlights: {yields} We identified four sequence motifs lying upstream of putative pro-longevity genes. {yields} One of these motifs binds to HNF-4{alpha}. {yields} HNF-4{alpha}/PGC-1{alpha} could up-regulate the transcription of a reporter gene linked to this motif. {yields} The reporter system described here could be used to screen candidate anti-aging molecules. -- Abstract: Suppression of the growth hormone/insulin-like growth factor-I pathway in Ames dwarf (DF) mice, and caloric restriction (CR) in normal mice extends lifespan and delays the onset of age-related disorders. In combination, these interventions have an additive effect on lifespan in Ames DF mice. Therefore, common signaling pathways regulated by DF and CR could have additive effects on longevity. In this study, we tried to identity the signaling mechanism and develop a system to assess pro-longevity status in cells and mice. We previously identified genes up-regulated in the liver of DF and CR mice by DNA microarray analysis. Motif analysis of the upstream sequences of those genes revealed four major consensus sequence motifs, which have been named dwarfism and calorie restriction-responsive elements (DFCR-REs). One of the synthesized sequences bound to hepatocyte nuclear factor-4{alpha} (HNF-4{alpha}), an important transcription factor involved in liver metabolism. Furthermore, using this sequence information, we developed a highly sensitive bioassay to identify chemicals mimicking the anti-aging effects of CR. When the reporter construct, containing an element upstream of a secreted alkaline phosphatase (SEAP) gene, was co-transfected with HNF-4{alpha} and its regulator peroxisome proliferator-activated receptor (PPAR) {gamma} coactivator-1{alpha} (PGC-1{alpha}), SEAP activity was increased compared with untransfected controls. Moreover, transient transgenic mice established using this construct showed increased SEAP activity in CR mice compared with ad libitum-fed mice. These data

L-cysteine efflux in erythrocytes as a function of human age: correlation with reduced glutathione and total anti-oxidant potential.

Thiol compounds such as cysteine (Cys) and reduced glutathione (GSH) play an important role in human aging and age-related diseases. In erythrocytes, GSH is synthesized by glutamic acid, cysteine, and glycine, but the rate of GSH synthesis is determined only by the availability of L-cysteine. Cysteine supplementation has been shown to ameliorate several parameters that are known to degenerate during human aging. We have studied L-cysteine efflux in vitro in human erythrocytes as a function of age by suspending cells in solution containing 10 mM L-cysteine for uptake; later cells were re-suspended in phosphate-buffered saline (PBS)-glucose to allow efflux. Change in the free sulfhydryl (-SH) concentration was then measured to calculate the rate of efflux. The GSH/oxidized glutathione (GSSG) ratio was taken as a control to study the oxidation/reduction state of the erythrocyte. The total anti-oxidant potential of plasma was measured in terms of ferric reducing ability of plasma (FRAP) values. We have shown a significant (pL-cysteine in erythrocytes during human aging, and the GSH/GSSG ratio decreases as a function of human age. The decline in L-cysteine efflux during aging correlates with the decrease in GSH and the FRAP value. This finding may help to explain the shift in the redox status and low GSH concentration that might determine the rate of L-cysteine efflux observed in erythrocytes and an important factor in the development of oxidative stress in erythrocytes during aging.

Spatio-temporal variation of nectar robbing in Salvia gesneriflora and its effects on nectar production and legitimate visitors.

Nectar robbing occurs when floral visitors remove floral nectar through floral damage and usually without providing pollination in return. Even though nectar robbing may have negative, neutral or even positive effects on plant fitness, few studies have investigated temporal and spatial variation in robbing rate and their consequences, particularly in the tropics. In this study, robbing levels were estimated during 3 years in four populations of Salvia gesneriflora, a hummingbird-pollinated shrub endemic to central Mexico that is mainly robbed by birds, carpenter bees and bumblebees. The effect of robbing on nectar availability, flower longevity and on visitation rate by floral visitors was also evaluated. Our results indicate great variation in robbing levels across years and populations and a positive relationship between robbing level and flower abundance per population. Moreover, our results show that nectar availability is about eight times higher in unrobbed flowers than in robbed flowers, and that nectar robbers prefer younger flowers, although lifespan of robbed and unrobbed flowers did not differ statistically. Primary and secondary nectar robbers showed a higher visitation rate compared to legitimate visitors, and neither legitimate nor illegitimate floral visitors seem to discriminate between robbed and unrobbed flowers. These results suggest that robbers may respond to food availability and that no floral visitors apparently could differentiate between robbed and unrobbed flowers. Finally, results show that nectar robbers prefer the youngest flowers, which suggests that strong competition for access to nectar between pollinators and robbers might occur, mainly at the first stages of the flowers. © 2015 German Botanical Society and The Royal Botanical Society of the Netherlands.

Full Text Available Human thioredoxin (TRX is a 12-kDa protein with redox-active dithiol in the active site -Cys-Gly-Pro-Cys-, which is induced by biological stress due to oxidative damage, metabolic dysfunction, chemicals, infection/inflammation, irradiation, or hypoxia/ischemia-reperfusion. Our research has demonstrated that exogenous TRX is effective in a wide variety of inflammatory diseases, including viral pneumonia, acute lung injury, gastric injury, and dermatitis, as well as in the prevention and amelioration of food allergies. Preclinical and clinical studies using recombinant TRX (rhTRX are now underway. We have also identified substances that induce the expression of TRX in the body, in vegetables and other plant ingredients. Skincare products are being developed that take advantage of the anti-inflammatory and anti-allergic action of TRX. Furthermore, we are currently engaged in the highly efficient production of pure rhTRX in several plants, such as lettuce, grain and rice.

Algae has been known as one of the potential marine bio-resources that have been used in many fields such as bio-energy, food, pharmaceutical and medical applications. Study of macro-algae or seaweed for medicine application, in particular, highlights to empower their ingredients as a promising antioxidant like anti-aging agent due to their diversity in biological activity. The tropical climate of Indonesia with the highest marine biodiversity puts this country an auspicious source of numerous alga species as a novel antioxidant source. A Sample of 29 species of macroalgae has been collected from Coast of Pari Island as a part of Seribu Islands, Indonesia. Screening and extracting of aqueous tropical marine alga protein as a potential source for an antioxidant agent has been done by using 2,2-diphenyl-1-picrylhydrazyl scavenging method, and protein contents have been determined by Lowry method. Sample number 26 of the phylum Rhodophyta have 9.00±0.03 % protein content, which is potential for nutritional food in form of nutraceutical. That sample demonstrated the maximum DPPH scavenging activity 79.27±1.81 %. Moreover, crude extract from another species from phylum Rhodophyta had the very lower IC50 (3.4333±0.29 mg/ml) followed by Chlorophyta species (7.1069±1.78 mg/ml). In general, this study found that algae from phylum Rhodophyta possess a high content of protein, high activity towards free radical. Nevertheless, algae acquire the lowest IC50 value not only dominated by Rhodophyta but also from phylum Chlorophyta. The conclusion of this study leads to empowering high antioxidant activity algae as an anti-aging agent, which can be used in pharmaceutical applications. Therefore, the next study should be concerned on the properties of the algae which has been known to be suitable for pharmaceutical fields.

Visual acuity (VA) outcomes differ considerably among patients with neovascular age-related macular degeneration (nAMD) treated with anti-vascular endothelial growth factor (VEGF) drugs. Identification of pharmacogenetic associations may help clinicians understand the mechanisms underlying this variability as well as pave the way for personalized treatment in nAMD. To identify genetic factors associated with variability in the response to anti-VEGF therapy for patients with nAMD. In this multicenter genome-wide association study, 678 patients with nAMD with genome-wide genotyping data were included in the discovery phase; 1380 additional patients with nAMD were genotyped for selected common variants in the replication phase. All participants received 3 monthly injections of bevacizumab or ranibizumab. Clinical data were evaluated for inclusion/exclusion criteria from October 2014 to October 2015, followed by data analysis from October 2015 to February 2016. For replication cohort genotyping, clinical data collection and analysis (including meta-analysis) was performed from March 2016 to April 2017. Change in VA after the loading dose of 3 monthly anti-VEGF injections compared with baseline. Of the 2058 included patients, 1210 (58.8%) were women, and the mean (SD) age across all cohorts was 78 (7.4) years. Patients included in the discovery cohort and most of the patients in the replication cohorts were of European descent. The mean (SD) baseline VA was 51.3 (20.3) Early Treatment Diabetic Retinopathy Study (ETDRS) score letters, and the mean (SD) change in VA after the loading dose of 3 monthly injections was a gain of 5.1 (13.9) ETDRS score letters (ie, 1-line gain). Genome-wide single-variant analyses of common variants revealed 5 independent loci that reached a P value less than 10 × 10-5. After replication and meta-analysis of the lead variants, rs12138564 located in the CCT3 gene remained nominally associated with a better treatment outcome (ETDRS letter

The process of oil filling will produce electrostatic phenomena which may cause fire accidents. There were no reports about research on the danger of static electricity generation in the process of gauging operation to date. This paper presents an experiment on charge transferring quantity of gauge rulers, and calculates the charge transferring quantity of an anti-electrostatic gauge ruler and a metal one, respectively. The results indicate that the charge transferring quantity can be more than 0.1 μC for a metal gauge ruler, while it is less than 0.1 μC for an antistatic gauge ruler. Therefore, this experimental research proves that using an anti-electrostatic gauge ruler is safer than using a metal one. This study also provides some theoretical and experimental evidence for making anti-electrostatic gauge rulers.

Anti-Müllerian hormone (AMH) is widely used in human medicine to non-invasively estimate the size of the ovarian follicle reserve and to predict the ovarian response to gonadotropin stimulation in the context of assisted reproductive technologies (e.g., IVF). These applications of AMH testing have recently expanded to non-human mammals, with production animals, such as cows, goats and sheep being the primary focus of AMH research. However, few investigations have involved exotic species, and in particular carnivores. In this study, we measured AMH concentrations (0.078-3.078ng/mL) in archived serum samples that had been collected from 36 adult female cheetahs across their reproductive lifespan (2-15years of age). Similar to other mammals, AMH concentration in cheetahs declined with age, and its variability among females of the same age was considerable. The rates at which AMH declined over time in individual cheetahs were also highly variable. Five cheetahs had been contracepted with the long-acting GnRH agonist deslorelin for 6-18months prior to sample collection, and their AMH concentrations were relatively low compared to untreated females. In this first study of AMH in an exotic carnivore, the findings demonstrate that the age-associated decline in AMH is highly variable and that deslorelin appears to suppress AMH concentration in serum. Owing to the increased use of assisted reproductive technologies in ex situ populations of threatened and endangered species, such as cheetahs, the present study's findings will need to be taken into consideration if AMH is to be used successfully to optimize breeding management decisions in exotic species.

A total of 1,333 persons in 627 families were surveyed for presence of antibody to adult T-cell leukemia-associated antigen (anti-ATLA). Each person was classified according to the anti-ATLA status (positive for sample 1, negative for sample 2) of the head of household of his or her family. In sample 1, the sex- and age-standardized prevalence of anti-ATLA was 38.5%. This was five times as high as the standardized prevalence in sample 2 (7.8%). There were significant differences in prevalence of anti-ATLA between males in samples 1 and 2 and between females in samples 1 and 2. In every age group, prevalence in sample 1 was greater than that in sample 2 except for males aged 60-69 years. In each of four subareas, families in sample 1 had higher standardized prevalence (29.6-42.5%) than families in sample 2 (6.0-9.7%). Although crude prevalence decreased with family size in sample 1 (62.1-25.4%) as well as in sample 2, indirectly standardized prevalence was almost equal within each sample, regardless of number of family members. The degree of aggregation was independent of locality and family size. These data suggest that anti-ATLA-positive persons aggregate in family units.

Full Text Available Abstract Introduction Cerebrovascular disease is a major cause of mortality and morbidity worldwide. Ischemic stroke is the most common manifestation, encompassing a wide variety of causative mechanisms. We present the case of a middle-aged male patient with spontaneous coronary artery dissection in the presence of anti-cardiolipin antibodies, leading to left ventricular thrombus and presenting with stroke. Case presentation A 56-year-old Caucasian man presented with dysarthria and right-sided weakness. There was a history of chest pain with autonomic symptoms four days earlier. Examination revealed right-sided hemiparesis. Electrocardiogram showed sinus rhythm with anterior Q waves. Magnetic resonance imaging of the brain showed large left parietal and smaller multiple cerebral infarcts. Echocardiogram showed anterior wall and apical akinesis with a large mural thrombus. Anti-cardiolipin antibodies immunoglobulin G and immunoglobulin M were strongly positive. Coronary angiography showed dissection of the mid left anterior descending artery with normal flow down the distal vessel. He was treated conservatively with anticoagulation and secondary prevention. He was in good health when seen in clinic four months later. Conclusion We highlight the importance of a comprehensive approach at obtaining the correct diagnosis, input of different specialities and the fact that the presence of anti-cardiolipin antibodies is associated with coronary artery dissection in a middle-aged male patient whose presentation was stroke.

G antigen of Rh blood group system is present either along with D and/or C positive red cells. Hence, [serologically anti-G presents with the similar picture as that of multiple antibodies (anti-D + anti-C). Differentiating them is important as anti-D + anti-C causes severe hemolytic disease of the fetus and newborn than anti-G. In pregnancies with anti-G alone, alloimmunization due to D antigen could be prevented by prophylactic administration of RhIg. Differentiating between anti-D + C from anti-G in alloimmunized pregnant mothers becomes essential. Sera from antenatal mothers, whose antibody identification by 11-cell panel gave a pattern for anti-D and anti-C were selected. Extended phenotyping for Rh system was performed for these antenatal cases. Differential adsorption and elution testing using R 2 R 2 cells initially and r'r cells subsequently were performed to distinguish anit-G from anti-D + anti-C. Antibody titers of these antibodies were determined and their clinical outcome in the newborn was followed. A pattern suggestive of anti D and anti C on antibody identification were observed in six antenatal cases. On further workup 50 % of them confirmed to have anti G. Antibody titers of anti-G and anti-C were lower than that of Anti-D. All newborns were sensitized in vivo and the antibody specificity in them were confirmed with elution studies. The mothers who had only anti-G were subsequently administered with an appropriate dose of RhIg.Differential adsorption and elution studies help in identifying anti-G and distinguishing it from anti-D plus anti-C, thus helping in better patient management.

Background Although the health effects of vitamin C are well known, its physiological effect on serum lipoproteins and microRNA still remain to be investigated, especially daily consumption of a high dosage. Objectives To investigate the physiological effect of vitamin C on serum lipoprotein metabolism in terms of its anti-oxidant and anti-glycation activities, and gene expression via microRNA regulation. Methods We analyzed blood parameters and lipoprotein parameters in young subjects (n = 46, 22 ± 2 years old) including smokers who consumed a high dose of vitamin C (1250 mg) daily for 8 weeks. Results Antioxidant activity of serum was enhanced with the elevation of Vit C content in plasma during 8 weeks consumption. In the LDL fraction, the apo-B48 band disappeared at 8 weeks post-consumption in all subjects. In the HDL fraction, apoA-I expression was enhanced by 20% at 8 weeks, especially in male smokers. In the lipoprotein fraction, all subjects showed significantly reduced contents of advanced glycated end products and reactive oxygen species (ROS). Triglyceride (TG) contents in each LDL and HDL fraction were significantly reduced in all groups following the Vit C consumption, suggesting that the lipoprotein was changed to be more anti-inflammatory and atherogenic properties. Phagocytosis of LDL, which was purified from each individual, into macrophages was significantly reduced at 8-weeks post-consumption of vitamin C. Anti-inflammatory and anti-senescence effects of HDL from all subjects were enhanced after the 8-weeks consumption. The expression level of microRNA 155 in HDL3 was reduced by 49% and 75% in non-smokers and smokers, respectively. Conclusion The daily consumption of a high dose of vitamin C for 8 weeks resulted in enhanced anti-senescence and anti-atherosclerotic effects via an improvement of lipoprotein parameters and microRNA expression through anti-oxidation and anti-glycation, especially in smokers.

Intermittent fasting-dietary restriction (IF-DR) is an increasingly popular intervention to promote healthy aging and delay age associated decline in brain functions. Also, the use of herbal interventions is gaining attention due to their non-pharmacological approach to treat several abnormalities and promote general health with least side effects. The present study was aimed to investigate the synergistic effects of IF-DR regimen with herbal supplementation on anxiety-like behavior and neuroinflammation in middle aged female rats. We used dried leaf powder of Withania somnifera and dried stem powder of Tinospora cordifolia for our study. The rats were divided into three groups: (1) Control group fed ad libitum (AL); (2) rats deprived of food for full day and fed ad libitum on every alternate day (IF-DR); and (3) IF-DR and herbal extract (DRH) group in which rats were fed ad libitum with herbal extract supplemented diet, every alternate day. Post regimen, the rats were tested for anxiety-like behavior and further used for study of key inflammatory molecules (NFκB, Iba1, TNFα, IL-1β, IL-6) and glial marker (GFAP) in hippocampus and piriform cortex regions of brain. The study was further extended to explore the effect of DRH regimen on stress response protein (HSP70) and calcium dependent regulators of synaptic plasticity (CaMKIIα, Calcineurin). Our data demonstrated that DRH regimen reduced anxiety-like behavior in middle age female rats and associated neuroinflammation by ameliorating key inflammatory cytokines and modulated stress response. The present data may provide scientific validation for anxiolytic and anti-inflammatory potential of herbal intervention combined with short term IF-DR regimen.

The fruits of Paulownia catalpifolia Gong Tong are used as a Chinese folk herbal medicine for the treatment of enteritis, tonsillitis, bronchitis, and dysentery, etc. Our previous study has identified new C-geranylated flavanones with obvious anti-proliferative effects in lung cancer A549 cells. In the present study, a new C-geranylated flavone, paucatalinone C (1) and five known C-geranylated flavanones (2-6) were isolated. In addition, a total of 34 C-geranylated flavonoids were detected by HPLC-DAD-ESI-MS/MS coupling techniques from the CH 2 Cl 2 extract of P. catalpifolia. Futhermore, anti-aging effects of isolated compounds were evaluated in vitro with premature senescent 2BS cells induced by H 2 O 2 . Phytochemical results indicated that P. catalpifolia was a natural resource of abundant C-geranylated flavonoids. Diplacone (3) and paucatalinone A (5) were the potent anti-aging agents in the premature senescent 2BS cells induced by H 2 O 2 and the C-geranyl substituent may be an important factor because of its lipophilic character.

Legitiming psychiatrists rather than curing patients. The shock therapy in Buenos Aires, Argentina (1930-1970

Directory of Open Access Journals (Sweden)

Alejandra Golcman

2017-06-01

Full Text Available This research aims to explain the theoretical and clinical use of shock therapies in Argentine psychiatric field, particularly in the province of Buenos Aires between 1930 and 1970. It is argued that it is necessary to study the theoretical and clinical psychiatric work, in order to learn how psychiatrists interpreted mental pathology. Thus two distinct scenarios are analyzed: first academia, emphasizing on medical texts expressing discussions held at congresses, conferences, university chairs, and secondly in hospital settings, represented by a population of chronic patients in a hospital on the outskirts of the Capital Federal, the Esteves Hospital of Lomas de Zamora. The use of shock therapy in the hands of psychiatrists, changed the way of understanding madness and transformed the daily course of hospitals. Therefore, the presence of such therapies was relevant to legitimize the discipline, regardless of the “effectiveness” with patients.

To explore the association between presence of subretinal drusenoid deposits (SDD) at baseline in eyes with neovascular age-related macular degeneration (nAMD) with the development of macular atrophy (MA) during anti-vascular endothelial growth factor (VEGF) therapy. There were 74 eyes without pre-existing MA receiving anti-VEGF therapy for nAMD for 2 years or longer analyzed. At least two image modalities that included spectral-domain optical coherence tomography, near-infrared reflectance, fluorescein angiography, and color fundus photos were used to assess for SDD presence, phenotype (dot and ribbon), and location, neovascularization type, and MA. Logistic regression models using generalized estimating equations assessed the association between SDD and the development of MA adjusting for age, neovascularization type, and choroidal thickness. SDD were present in 46 eyes (63%) at baseline. MA developed in 38 eyes (51%) during the mean of 4.7 ± 1.2 years of follow-up. Compared with eyes without SDD, those with SDD at baseline were 3.0 times (95% confidence interval [CI] 1.1-8.5, P = 0.0343) more likely to develop MA. Eyes with SDD present in the inferior macula and inferior extramacular fields at baseline were 3.0 times and 6.5 times more likely to develop MA at follow-up than eyes without SDD in these locations (95% CI 1.0-8.9, P = 0.0461 and 95% CI 1.3-32.4, P = 0.0218, respectively). MA development was not associated with a specific SDD phenotype. MA frequently developed in eyes during anti-VEGF treatment. SDD were independently associated with MA development. The extension of SDD into the inferior fundus, particularly in the inferior extramacular field, conferred higher odds of subsequent MA development.

To investigate the neuroprotective effects of saponins from Panax japonicus (SPJ) on D-galactose (D-gal)-induced brain ageing, and further explore the underlying mechanisms. SPJ were analysed using high-pressure liquid chromatography. Male Wistar rats weighing 200 ± 20 g were randomly divided into four groups: control group (saline), D-gal-treated group (400 mg/kg, subcutaneously), D-gal + SPJ groups (50, 100 and 200 mg/kg, orally) and vitamin E group (100 mg/kg). Rats were injected corresponding drugs once daily for 8 weeks. Neuroprotective effects of SPJ were evaluated by Morris water maze, histopathological observations, biochemical assays, western blot analysis and quantitative real-time polymerase chain reaction (PCR) analysis in vivo as well as reactive oxygen species (ROS) measurement and apoptosis assay in vitro. Our present study showed that D-gal had a neurotoxic effect in rats and in SH-SY5Y cells due to oxidative stress induction, including decreased total anti-oxidant capacity, superoxide dismutase (SOD) and glutathione peroxidase activity, ultimately leading to spatial learning and memory impairment in rats and ROS accumulation in SH-SY5Y cells. SPJ improved spatial learning and memory deficits, attenuated hippocampus histopathological injury and restored impaired anti-oxidative as well as anti-apoptotic capacities in D-gal-induced ageing rats. In addition, SPJ remarkably decreased lipofuscin levels, increased hippocampus nuclear factor erythroid 2-related factor 2 (Nrf2) and silent mating type information regulation 2 homologue (SIRT1) protein levels and anti-oxidant genes expression such as manganese superoxide dismutase (Mn-SOD), heme oxygenase (HO-1), NAD(P)H quinone oxidoreductase 1 (NQO1) and cysteine ligase catalytic (GCLC) in D-gal-induced brain ageing. Our data suggested that D-gal induced multiple molecular and functional changes in brain similar to natural ageing process. SPJ protected brain from D-gal-induced neuronal

Pedestrians slipping and falling is a major safety problem around the world, not least in countries with long winters such as Sweden. About 25000-30000 people need medical care every year for treatment of fall injuries in Sweden. Use of appropriate shoes and anti-slip devices are examples of individual measures that have been suggested to prevent slipping and falling. An intervention study was performed during the period February to April 2008. The study, which focused on healthy adults in northern Sweden, examined the effect of using anti-slip devices on daily walking journeys and prevention of slip and falls. The respondents were divided into three groups: an Intervention Group, a Control Group, with similar distribution of gender and age, and a Comparison Group. Four questionnaires were distributed: (1) background, (2) daily diary of distance walked and occurrence of incidents or accidents reported weekly, (3) detailed incident or fall report and (4) experiences of using anti-slip devices for those who used these devices during the trial period. Half of the respondents stated that they had previous experience of using anti-slip devices. In this study, 52% of the respondents used anti-slip devices. Anti-slip devices improve the walking capability during wintertime. Among those using appropriate anti-slip devices, the average daily walking distance was found to be statistically significantly longer compared to people not using anti-slip devices. This study indicates that an increase in daily walking distance can be made without increasing the risk of slips/falls when using anti-slip devices. The study also indicates that by using appropriate anti-slip devices and having information about when and where to use them, based on their design, people avoid having slips and falls. The respondents experienced in using anti-slip devices in this study will continue to use them and will also recommend others to use anti-slip devises. Copyright 2010 Elsevier Ltd. All rights

The purpose of this study was to compare the association between anti and pro-oxidant activity, nitrite concentration, and blood pressure (BP) in middle-aged and older women with different levels of estimated training status (TS). The sample consisted of 155 females (50-84 years) who were submitted to a physical examination to evaluate estimated TS through the "Functional Fitness Battery Test," BP measurements, and plasma blood samples to evaluate pro-oxidant and antioxidant activity and nitrite concentrations. Participants were separated by age into a middle-aged group (<65 years) and an older (≥65 years) group and then subdivided in each group according to TS. Blood biochemistry was similar between groups. On the other hand, protein oxidation was lower in participants with higher TS, independent of age. Older females with higher TS presented higher nitrite concentrations, lower lipoperoxidation, and lower values of BP compared with those with lower TS. Lower GPx activity was observed in participants with higher TS compared with middle-aged with lower TS. Thus, our results suggest that good levels of TS may be associated with lower oxidative stress and higher nitrite concentration and may contribute to maintain normal or reduced blood pressure values.

Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is a recently identified auto-immune disorder characterised by severe memory deficit, a decreased level of consciousness, seizures, autonomic dysfunction and movement disorders. Three girls with the disorder are reported; they were aged 4 years, 5 years and 10 months. The 10-month-old infant who is one of the youngest patients reported with anti-NMDAR encephalitis worldwide, had MRI features suggestive of herpes simplex encephalitis (known to trigger anti-NMDAR encephalitis), but CSF PCR for herpes simplex was negative. All the patients presented with seizures, behavioural change, regression of speech, dystonia and choreo-athetosis. Anti-NMDAR antibodies were detected in all patients' sera and cerebrospinal fluid (CSF). Intravenous immunoglobulin, corticosteroids and rituximab were administered at different intervals. Cases 1 and 2 made a full recovery, but case 3 has mild motor and speech delay. Patients who present with encephalopathy, seizures and movement disorders should be tested for anti-NMDAR antibodies in serum and CSF in addition to being screened for herpes simplex encephalitis.

Full Text Available Celiac disease (CD is a chronic enteropathy caused by hypersensitivity to gluten. Most studies have showed more prevalence of CD in the patients with diabetes mellitus type 1. Both diseases are autoimmune and their incidence is related to inheritance and environmental factors. The aim of this research is the study of relation between CD prevalence and diabetic age onset. Materials and Methods: In this descriptive cross-sectional study, 135 children with diabetes mellitus type 1 referring to Tabriz children hospital endocrine department and clinic between 2006-2008 were selected. After filling individual identity of the patients and the measurement of weight and height, the serumic level of anti-tissue Trans glutaminase IgA antibody (A-tTG-A-IgA, anti endomisial IgA antibody (AEA-IgA and anti-gliadin IgG antibody (AGA-IgG were measured. In the case that A-tTG-A either AEA alone or with AGA was high, small intestinal biopsy was preformed. The data was analysed using SPSS ver 16 software. Results: 28 of 135 patients with diabetes mellitus type 1, were serologically positive for celiac. Confirmed celiac prevalence based on biopsy was 6. 8%. From diabetic age onset and celiac incidence point of view there was not any significant relation (P=0. 996. Conclusion: Celiac disease in type1 diabetic patients dose not have correlation with the onset age of type 1 diabetes and diabetic patients should be followed up from celiac point of view during treatment and prevention.

As control group, 33 age- and-sex-matched healthy children (HC were also examined. Results: Abs to chromatin were detected in 24/94 (25,5% of children suffering from JRA. Particularly, the higher prevalence of anti-chromatin Abs has been found in children with oligoarticular (30,4% and polyarticular (23,7% onset JRA. In these groups Abs titers were significantly higher compared to systemic JRA and HC (p=0.003. Anti-chromatin Abs were observed more frequently in patients with oligoarticular disease and chronic uveitis (21,7%. Furthermore, higher levels of anti-chromatin Abs has been found in all the patients treated with anti-TNFα therapy (p<0.0001. Conclusions: our results confirm previous data about the prevalence of anti-chromatin Abs in JRA. These Abs were significantly higher in the group of patients with oligoarticular onset with past or present hystory of ocular involvement and in the group with polyarticular JRA treated with biologic therapy. A long-term follow-up study could be useful to evaluate the potential utility of these autoantibodies.

Toxoplasma gondii infection may be associated with psychiatric disorders due to its neurological effects. The purpose of this study was to investigate the relation between tic disorders in children and adolescents and Anti-Toxoplasma IgG. 43 children diagnosed with Tourette's syndrome(TS) and 87 with chronic motor or vocal tic disorder(CMVTD), and 130 healthy volunteers, all aged 7-18, were enrolled. Anti-Toxoplasma IgG antibody levels obtained from blood specimens were investigated. Toxoplasma IgG positivity was determined in 16(37.2%) of the patients with TS, in 27(31%) of those with CMVTD and in 12(9.2%) members of the control group. Anti-Toxoplasma gondii antibody positivity was 5.827-fold higher in subjects with TS and 4.425-fold higher in subjects with CMVTD compared to the control group. Correlation was determined between a diagnosis of TS or CMVTD and Anti-Toxoplasma gondii antibodies. We think that it will be useful for the neuropsychiatric process associated with Anti-Toxoplasma gondii antibodies to be clarified. Copyright © 2018 Elsevier B.V. All rights reserved.

Full Text Available Abstract Background The prevalence of Crohn's disease (CD is increased in patients with cystic fibrosis (CF. Anti-Saccharomyces cerevisiae antibodies (ASCA have been suggested as a screening tool to detect CD in CF. Recently, several new anti-glycan antibodies have been reported in CD. Materials and methods The sera of 119 CF patients of various age groups were prospectively screened for ASCA type IgG (gASCA, anti-laminaribioside carbohydrate IgG antibodies (ALCA, anti-chitobioside carbohydrate IgA antibodies (ACCA, and anti-mannobioside carbohydrate IgG antibodies (AMCA. The frequency of these anti-glycan antibodies was then compared in patients with CD, ulcerative colitis, rheumatoid arthritis and healthy volunteers. Results A significant number of CF patients were positive for gASCA (51.3% [41.6-60.6] and up to three other anti-glycan antibodies concurrently. Serum levels of anti-glycan antibodies in CF and CD were not related to parameters of inflammation. Despite the well-documented difference in clinical course between male and female CF patients no gender difference of anti-glycan antibodies was found. In contrast, there was a significant positive correlation between anti-glycan markers and age in CF patients. Conclusions Our findings demonstrate for the first time the increased frequency of a panel of anti-glycan antibodies in CF and provide a link between the presence of these serological biomarkers and patient's age. Anti-glycan antibody profiling may therefore become a valuable tool in the care of patients with CF.

Full Text Available Scientific arguments in favour of applying physical exercise as an intervention on "aging" insists on relying on the biological concept of health. Considering the hegemony of this concept in physical education, the present study questions in what extent it must be accepted that the relationship between health/aging remains summarized in the mere search for maintaining physiological capabilities? The aim was to analyse the problematizations on the relationship between health and exercise in a group of physically active women from the city of Recife, Pernambuco, Brazil, in the context of aging process. Forty-five amateur bodybuilders were selected utilizing the sample snowball technique. They answered an interview guide with pictures according to the photo elicitation technique, individually. It was utilized the speech analysis proposed by Foucault. The group understands the relationship health/aging as a way to build identities, overcoming the negative perception of old age as vital and negative process. The fear of aging denotes the presence of self-centred healthcare practices carried over the years. Physical exercise plays a role that transcends the mere control of biological variables, being a resource to strengthen the experience to look and feel younger.

1995-02-01

Using the ARGUS detector at the e + e - storage ring DORIS II at DESY, a study of the decay anti B 0 →D *+ l - anti νhas been performed by exploiting a partial D *+ reconstruction technique. The branching ratio was determined to be (4.4±0.3±0.3)% for this mode, and for the higher excited D * (J) states Br( anti B 0 →D (J) *+ l - anti ν)=(2.5±0.6±0.5)%. Furthermore, the inclusive D *+ branching ratio in B decays was measured by fully reconstructing D *+ candidates. Using a tagged subset of this sample of B 0 meson decays in the mode anti B 0 →D *+ l - anti ν, B d 0 anti B d 0 oscillations have been studied. For this purpose two tagging techniques have been applied: the standard method of using fast leptons, and a new technique which makes use of kaons to tag the b flavour content. Combining the values obtained by these two methods, the B 0 anti B 0 mixing parameter χ d , used to denote the strength of the oscillations, was determined to be χ d =0.165±0.057. In addition, using fully reconstructed D *+ candidates, a third study of the B 0 anti B 0 mixing parameter was carried out by investigating D *+ K ± correlations. The mixing measurements obtained using kaons to tag the B meson flavour employ this technique for the first time. Future CP violation measurements at B Factories will place critical reliance on this method. Finally, using the extracted value for the mixing parameter χ d , the CKM matrix element V td was determined and the B s 0 anti B s 0 mixing parameter χ s was obtained. (orig.)

Full Text Available Background: Amyloidosis, oxidative stress and inflammation have been strongly implicated in neurodegenerative disorders like Alzheimer′s disease. Traditionally, Caesalpinia crista and Centella asiatica leaf extracts are used to treat brain related diseases in India. C. crista is used as a mental relaxant drink as well as to treat inflammatory diseases, whereas C. asiatica is reported to be used to enhance memory and to treat dementia. Objective: The present study is aimed to understand the anti-oxidant and anti-inflammatory potential of C. asiatica and C. crista leaf extracts. Materials and Methods: Phenolic acid composition of the aqueous extracts of C. crista and C. asiatica were separated on a reverse phase C18 column (4.6 x 250 mm using HPLC system. Antioxidant properties of the leaf extracts were determined by 1,1-diphenyl-2-picrylhydrazyl (DPPH radical scavenging assay and the reducing potential assay. The anti-inflammatory activities of aqueous extracts of C. crista and C. asiatica were studied using 5-lipoxygenase assay. Polymorphonuclear leukocytes (PMNLs were isolated from blood by Ficoll-Histopaque density gradient followed by hypotonic lysis of erythrocytes. Results: Gallic, protocatechuic, gentisic, chlorogenic, caffeic, p-coumaric and ferulic acids were the phenolic acids identified in C. crista and C. asiatica leaf aqueous extracts. However, gallic acid and ferulic acid contents were much higher in C. crista compared to C. asiatica. Leaf extracts of C. asiatica and C. crista exhibited antioxidant properties and inhibited 5-lipoxygenase (anti-inflammatory in a dose dependent manner. However, leaf extracts of C. crista had better antioxidant and anti-inflammatory activity compared to that of C. asiatica. The better activity of C. crista is attributed to high gallic acid and ferulic acid compared to C. asiatica. Conclusions: Thus, the leaf extract of C. crista can be a potential therapeutic role for Alzheimer′s disease.

The modern mental health system in Nepal: organizational persistence in the absence of legitimating myths.

Tausig, M; Subedi, S

1997-08-01

This paper advances an organizational explanation for the slow pace of modernization of mental health care systems in developing societies. In complement to cultural and political economic explanations of this condition, we suggest that the value of establishing modern systems in developing societies lies in the legitimation such structures provide for indigenous modernizing efforts vis-a-vis both indigenous and external audiences. The system need not meet actual levels of service demand. Its importance is in its symbolic value as an indicator of modernity. The result is a system in "permanent failure". Implications for institutional theory and the growth of modern mental health systems in developing societies are discussed.

Exclusive semileptonic B decays with a D *+ meson in the final state have been studied using the ARGUS detector at the DORIS II storage ring. The branching ratio for the decay anti B 0 →D *+ l - anti ν, where l - is either e - or μ - , has been measured to be (5.2±0.5±0.6)%. A significant rate for the decay anti B→D ** l - anti ν has been observed. From an angular analysis of the cascade anti B 0 →D *+ (→D 0 π + )l - anti ν the forward-backward asymmetry A FB and the D *+ polarization parameter α have been determined to be A FB =0.20±0.08±0.06 and α=1.1±0.4±0.2.

Full Text Available The article aims to describe and compare journalistic frames of climate change produced by two leading newspapers in South America: Clarin of Argentina and Folha de São Paulo of Brazil, in the context of the Doha (COP- 18 and Warsaw (COP -19 conferences. For this, it has used a definition of framing which recognizes its various dimensions: definition of the situation, reasoning about causes, moral evaluations and recommendations or prescriptions. The analysis was addressed by a qualitative process of coding and classification of journalistic texts. The empirical results indicate that the frames produced for the newspapers correspond to the political context to which they belong, that they coincide in pointing to climate change as a serious problem caused primarily by industrialized countries and what must be faced with a sense of urgency, so they tend to legitimate climate policy. In this regard, it is noted that journalistic frames not only guide the interpretation of social problems, but legitimate political action.

Advanced Glycation End-Products (AGEs) are signaling proteins associated to several vascular and neurological complications in diabetic and non-diabetic patients. AGEs proved to be a marker of negative outcome in both diabetes management and surgical procedures in these patients. The reported role of AGEs prompted the development of pharmacological inhibitors of their effects, giving rise to a number of both preclinical and clinical studies. Clinical trials with anti-AGEs drugs have been gradually developed and this review aimed to summarize most relevant reports. Evidence acquisition process was performed using PubMed and ClinicalTrials.gov with manually checked articles. Pharmacological approaches in humans include aminoguanidine, pyridoxamine, benfotiamine, angiotensin converting enzyme inhibitors, angiotensin receptor blockers, statin, ALT-711 (alagebrium) and thiazolidinediones. The most recent promising anti-AGEs agents are statins, alagebrium and thiazolidinediones. The role of AGEs in disease and new compounds interfering with their effects are currently under investigation in preclinical settings and these newer anti-AGEs drugs would undergo clinical evaluation in the next years. Compounds with anti-AGEs activity but still not available for clinical scenarios are ALT-946, OPB-9195, tenilsetam, LR-90, TM2002, sRAGE and PEDF. Despite most studies confirm the efficacy of these pharmacological approaches, other reports produced conflicting evidences; in almost any case, these drugs were well tolerated. At present, AGEs measurement has still not taken a precise role in clinical practice, but its relevance as a marker of disease has been widely shown; therefore, it is important for clinicians to understand the value of new cardiovascular risk factors. Findings from the current and future clinical trials may help in determining the role of AGEs and the benefits of anti-AGEs treatment in cardiovascular disease.

Hemolytic disease of the fetus and newborn (HDFN) is a severe disease, resulting from maternal red cell (RBC) alloantibodies directed against fetal RBCs. The effect of a first-trimester antibody screening program on the timely detection of HDFN caused by antibodies other than anti-D was evaluated. Nationwide, all women (1,002 in 305,000 consecutive pregnancies during 18 months) with alloantibodies other than anti-D, detected by a first-trimester antibody screen, were included in a prospective index-cohort study. In a parallel-coverage validation study, patients with HDFN caused by antibodies other than anti-D, that were missed by the screening program, were retrospectively identified. The prevalence of positive antibody screens at first-trimester screening was 1,232 in 100,000; the prevalence of alloantibodies other than anti-D was 328 in 100,000, of which 191 of 100,000 implied a risk for occurrence of HDFN because the father carried the antigen. Overall, severe HDFN, requiring intrauterine or postnatal (exchange) transfusions, occurred in 3.7 percent of fetuses at risk: for anti-K in 11.6 percent; anti-c in 8.5 percent; anti-E in 1.1 percent; Rh antibodies other than anti-c, anti-D, or anti-E in 3.8 percent; and for antibodies other than Rh antibodies or anti-K, in none of the fetuses at risk. All affected children, where antibodies were detected, were promptly treated and healthy at the age of 1 year. The coverage validation study showed a sensitivity of the screening program of 75 percent. Five of 8 missed cases were caused by anti-c, with delay-induced permanent damage in at least 1. First-trimester screening enables timely treatment of HDFN caused by antibodies other than anti-D, however, with a sensitivity of only 75 percent. A second screening at Week 30 of c- women will enhance the screening program. Severe HDFN, caused by antibodies other than anti-D, is associated with anti-K, anti-c, and to a lesser extent with other Rh-alloantibodies.

[Atrophy of the macula in the context of its wet, age-related degeneration : An inescapable consequence of anti-VEGF therapy?

Science.gov (United States)

Garweg, J G

2016-12-01

Current understanding of the mechanisms that underlie the long-term consequences of anti-VEGF therapy in wet, age-related macular degeneration (AMD) is poor. Here, the impact of this treatment on the development of macular atrophy (MA) is discussed based on our current pathophysiological understanding. This review is based on a PubMed literature survey using the MeSH terms "wet AMD" and "macular atrophy" (151 hits) and limited to publications since 2013 (n = 90). Publications focussing on diagnostics and clinical course not in the context of therapy were excluded. Macular atrophy is defined herein as atrophy affecting the functionally relevant complex of photoreceptors, retinal pigmented epithelium (RPE), Bruch's membrane and choriocapillaris. Experimentally, a primary complete suppression of local VEGF leads to evident changes in the choriocapillaris, whereas its incomplete suppression exacerbates cell death of RPE and photoreceptors. Since pre-existing atrophic changes are already present at diagnosis, the role of anti-VEGF treatment cannot be separated from the spontaneous progression of AMD. The progression of MA appears to be faster under ranibizumab than bevacizumab, and likewise on a monthly rather than as-needed basis. Although MA progresses more rapidly under consequent therapy, visual function remains better. Hence, a functionally relevant progression of atrophy during the first five years of treatment would only be expected in pre-existing advanced MA. Despite doubts regarding the long-term safety of anti-VEGF therapy, it is the author's view that this is the only option to stabilise visual function. The impact of therapy-induced damage on the spontaneous progression of AMD and the biological status of the aging individual cannot be unequivocally assessed.

The purpose of this study was to compare the association between anti and pro-oxidant activity, nitrite concentration, and blood pressure (BP) in middle-aged and older women with different levels of estimated training status (TS). The sample consisted of 155 females (50–84 years) who were submitted to a physical examination to evaluate estimated TS through the “Functional Fitness Battery Test,” BP measurements, and plasma blood samples to evaluate pro-oxidant and antioxidant activity and nitrite concentrations. Participants were separated by age into a middle-aged group (<65 years) and an older (≥65 years) group and then subdivided in each group according to TS. Blood biochemistry was similar between groups. On the other hand, protein oxidation was lower in participants with higher TS, independent of age. Older females with higher TS presented higher nitrite concentrations, lower lipoperoxidation, and lower values of BP compared with those with lower TS. Lower GPx activity was observed in participants with higher TS compared with middle-aged with lower TS. Thus, our results suggest that good levels of TS may be associated with lower oxidative stress and higher nitrite concentration and may contribute to maintain normal or reduced blood pressure values.

The patient's age is a key factor determining success of in vitro fertilization. The ovarian reserve and oocyte quality are known to decrease with age. Much attention has been given recently to the role of epiphysis and its hormone, melatonin, in synchronization of daily and seasonal biorhythms in anti-stress protection and neuroregulation of reproductive processes. The aim of our work was to study melatonin levels in infertile women of reproductive age. We also measured sex hormones, anti-Mullerian hormone, FSH, and LH in blood and melatonin sulfate in urine at 8 points (RIA). Women of advanced reproductive age showed markedly reduced melatonin secretion due to functional disorders in the hypothalamic-pituitary-gonadal axis. Results of the study suggest the necessity of prescription of exogenous melatonin to the patients included in assisted reproduction programs for the improvement of their efficacy.

There has been an increase in the interest of anti-ageing medicine in the last few years, with a growth in the industry of products that promise to prolong life and restore all the suffering or "defects" produced by age. The understanding of ageing has changed over the years, giving rise to the possibility of intervening in different metabolic and cellular pathways, and thus, delaying the appearance of the degenerative chronic diseases that appear with age, and that are finally the causing factors of the vulnerability that leads to our death. It is hoped that we can help the clinician to orientate their patients, who, due to the overwhelming amount of information they receive by the Internet, arrive at the clinic full of questions, waiting to receive absolute answer from their physician in order to increase their longevity and quality of life. This article presents an analysis of the physical activity, diets, supplements and drugs that are being investigated as anti-ageing measures and of the many clinical studies that have produced encouraging, measurable and reproducible results.

The Naturalization of Domination and Legitimate Power in Classical Political Theory

Directory of Open Access Journals (Sweden)

Eleni Varikas

2003-01-01

Full Text Available The reflection developed here deals with one of the greatest political paradoxes of modern political thought: the turning of a political community into a human artifact while basing it on premisses which are pre-political and therefore precede human action. As it reinvented the political as a free space, modernity reinvented the natural as a limit to this human freedom which religion could no longer contain. In such a context, the witch-hunt is a result both of a religious or superstitious obscurantism and of a rational enterprise based on efficacy. The political implications of cognitive polytheism, which explode in the plurality of scientific perceptions on human nature and on the nature of things, establish a close connection between the authority of modern “science” as a model for the knowledge of nature and that of a religious and temporal kind. The naturalization of the sexual hierarchy in the modern world is at the same time the archetype and the manifestation of this historical process which dislocates the legitimation of domination from the religious to the natural realm.

It is an important and difficult research point to recognize the age of Chinese liquor rapidly and exactly in the field of liquor analyzing, which is also of great significance to the healthy development of the liquor industry and protection of the legitimate rights and interests of consumers. Spectroscopy together with the pattern recognition technology is a preferred method of achieving rapid identification of wine quality, in which the Raman Spectroscopy is promising because of its little affection of water and little or free of sample pretreatment. So, in this paper, Raman spectra and support vector regression (SVR) are used to recognize different ages and different storing time of the liquor of the same age. The innovation of this paper is mainly reflected in the following three aspects. First, the application of Raman in the area of liquor analysis is rarely reported till now. Second, the concentration of studying the recognition of wine age, while most studies focus on studying specific components of liquor and studies together with the pattern recognition method focus more on the identification of brands or different types of base wine. The third one is the application of regression analysis framework, which cannot be only used to identify different years of liquor, but also can be used to analyze different storing time, which has theoretical and practical significance to the research and quality control of liquor. Three kinds of experiments are conducted in this paper. Firstly, SVR is used to recognize different ages of 5, 8, 16 and 26 years of the Gujing Liquor; secondly, SVR is also used to classify the storing time of the 8-years liquor; thirdly, certain group of train data is deleted form the train set and put into the test set to simulate the actual situation of liquor age recognition. Results show that the SVR model has good train and predict performance in these experiments, and it has better performance than other non-liner regression method such

We aimed to analyze the clinical and histopathologic features of cancer-associated myositis (CAM) in relation to anti-transcriptional intermediary factor 1 γ antibody (anti-TIF1-γ-Ab), a marker of cancer association. We retrospectively studied 349 patients with idiopathic inflammatory myopathies (IIMs), including 284 patients with pretreatment biopsy samples available. For the classification of IIMs, the European Neuromuscular Center criteria were applied. Patients with CAM with (anti-TIF1-γ-Ab[+] CAM) and without anti-TIF1-γ-Ab (anti-TIF1-γ-Ab[-] CAM) were compared with patients with IIM without cancers within and beyond 3 years of myositis diagnosis. Cancer was detected in 75 patients, of whom 36 (48%) were positive for anti-TIF1-γ-Ab. In anti-TIF1-γ-Ab(+) patients with CAM, cancers were detected within 1 year of myositis diagnosis in 35 (97%) and before 1 year of myositis diagnosis in 1. All the anti-TIF1-γ-Ab(+) patients with CAM satisfied the dermatomyositis (DM) criteria, including 2 possible DM sine dermatitis cases, and were characterized histologically by the presence of perifascicular atrophy, vacuolated fibers (VFs), and dense C5b-9 deposits on capillaries (dC5b-9). In contrast, 39 anti-TIF1-γ-Ab(-) patients with CAM were classified into various subgroups, and characterized by a higher frequency of necrotizing autoimmune myopathy (NAM). Notably, all 7 patients with CAM classified into the NAM subgroup were anti-TIF1-γ-Ab(-) and exhibited no dC5b-9 or VFs. CAM includes clinicohistopathologically heterogeneous disease entities. Among CAM entities, anti-TIF1-γ-Ab(+) CAM has characteristically shown a close temporal association with cancer detection and the histopathologic findings of dC5b-9 and VFs, and CAM with NAM is a subset of anti-TIF1-γ-Ab(-) CAM. © 2016 American Academy of Neurology.

Increasing numbers of patients with elevated anti-N-methyl-D-aspartate (NMDA) receptor antibody titers presenting exclusively with psychiatric symptoms have been reported. The aim of the present study was to clarify the prevalence of elevated serum anti-NMDA receptor antibody titers in patients with new-onset or acute exacerbations of psychiatric symptoms. In addition, the present study aimed to investigate the association between elevated anti-NMDA receptor titers and psychiatric symptoms. The present collaborative study included 59 inpatients (23 male, 36 female) presenting with new-onset or exacerbations of schizophrenia-like symptoms at involved institutions from June 2012 to March 2014. Patient information was collected using questionnaires. Anti-NMDA receptor antibody titers were measured using NMDAR NR1 and NR2B co-transfected human embryonic kidney (HEK) 293 cells as an antigen (cell-based assay). Statistical analyses were performed for each questionnaire item. The mean age of participants was 42.0 ± 13.7 years. Six cases had elevated serum anti-NMDA antibody titers (10.2 %), four cases were first onset, and two cases with disease duration >10 years presented with third and fifth recurrences. No statistically significant difference in vital signs or major symptoms was observed between antibody-positive and antibody-negative groups. However, a trend toward an increased frequency of schizophrenia-like symptoms was observed in the antibody-positive group. Serum anti-NMDA receptor antibody titers may be associated with psychiatric conditions. However, an association with specific psychiatric symptoms was not observed in the present study. Further studies are required to validate the utility of serum anti-NMDA receptor antibody titer measurements at the time of symptom onset.

The radioimmunotherapy (RIT) uses MAbs conjugated to radionuclides α or β - emitters, both for therapy. Your treatment is based on the irradiation and tumor destruction, preserving the normal organs as the excess radiation. Radionuclides β - emitters as 131 I, 90 Y, 188 Re 177 Lu and are useful for the development of therapeutic radiopharmaceuticals and, when coupled with MAb and Anti-CD20 it is important mainly for the treatment of non-Hodgkin's lymphomas (NHL). 188 Re (E β = 2.12 MeV; E γ = 155 keV; t1/2 = 16.9 h) is an attractive radionuclide for RIT. However, 188 Re can be obtained from a radionuclide generator of 188 W/ 188 Re, commercially available, making it convenient for use in research and for clinical routine. The CR of IPEN has a project aimed at the production of radiopharmaceutical 188 Re-Anti-CD20, where the radionuclide can be obtained from a generator system 188 W/ 188 Re. With this proposed a study to assess the efficiency of this labeling technique for treatment in accordance compartmental and dosimetry. The objective of this study was to compare the marking of anti-CD20 MAb with 188 Re with the marking of the antibody with 90 Y, 131 I, 177 Lu and 99m Tc (for their similar chemical characteristics) and 211 At, 213 Bi, 223 Ra and 225 Ac); through the study of labeling techniques reported in literature, the proposal of a compartmental model to evaluate its pharmacokinetic and dosimetric studies, high interest for therapy. The result of the study shows a favorable kinetics for 188 Re, by their physical and chemical characteristics compared to the other evaluated radionuclides. The compartment proposed study describes the metabolism of 188 Reanti- CD20 through a compartment mammillary model, which by their pharmacokinetic analysis, performed compared to products emitters β -131 I-labeled anti CD20, 177 Luanti- CD20, the γ emitter 99m Tc-Anti-CD20 and α emitter 211 At-Anti-CD20 presented a elimination constant of approximately 0.05 hours

Background: Recurrent pregnancy loss is a major health problem effecting 1 to 2% of women of reproductive age. Its causes range from chromosomal abnormalities to endocrinological factors and thrombophilia related factors. Treating thrombophilia s especially anti phospholipid syndrome with low dose aspirin and low molecular weight heparin improves foetal outcome. This study will add local data to already existing knowledge. Method: Sixty selected patients from gynaecology OPD of Aero Hospital with clinical and/or serological findings of anti phospholipid syndrome from February 2009 to January 2011 were given aspirin 75 mg once daily and enoxaparine 40 mg subcutaneously once daily from 6 - 8 weeks to 35 and 37 weeks respectively. Results : Ninety-three percent of patients achieved live birth. Out of these 75% patients delivered at term and 18% had preterm delivered. Four (7%) had early pregnancy loss and only one had early neonatal death due to extreme prematurity. None of patients experienced any major hemorrhagic complications . Conclusion: Use of low dose aspirin and low molecular weight heparin is safe in pregnancy and improve foetal outcome in patients with recurrent pregnancy loss due to anti phospholipids syndrome.

Full Text Available The Unani eye drop is an ophthalmic formulation prepared for its beneficial effects in the inflammatory and allergic conditions of the eyes. In the present study, the Unani eye drop formulation was prepared and investigated for its anti-inflammatory and antihistaminic activity, using in vivo and in vitro experimental models respectively. The Unani eye drop formulation exhibited significant anti-inflammatory activity in turpentine liniment-induced ocular inflammation in rabbits. The preparation also showed antihistaminic activity in isolated guinea-pig ileum. The anti-inflammatory and antihistaminic activity of eye drop may be due to presence of active ingredients in the formulation. Although there are many drugs in Unani repository which are mentioned in classical books or used in Unani clinical practice effectively in treatment of eye diseases by various Unani physicians. Inspite of the availability of vast literature, there is a dearth of commercial Unani ocular preparations. So, keeping this in mind, the eye drop formulation was prepared and its anti-inflammatory and antihistaminic activity was carried out in animal models. Thus, in view of the importance of alternative anti-inflammatory and anti- allergic drugs, it becomes imperative to bring these indigenous drugs to the front foot and evaluate their activities.

Full Text Available The aims of this study were to investigate the potential benefits of antioxidant, anti-inflammatory, anti-hepatotoxic, and anti-tyrosinase activities of a methanolic extract of fresh tea leaves (FTE (Camellia sinensis L.. The antioxidant capacity was investigated using three different methods at different temperatures. The anti-inflammatory activity was studied in vitro by the inhibition of 5-lipoxygenase assay. The anti-hepatotoxic effect was investigated in CCl4-induced liver injury in rats. The anti-tyrosinase activities of the FTE and its principal phenolic compounds were investigated in l-3,4-dihydroxyphenylalanine (l-DOPA oxidation by a mushroom tyrosinase. A molecular docking study was conducted to determine how the FTE’s principal catechins interact with the tyrosinase. The FTE exhibited the best shelf life at low temperatures and demonstrated concentration-dependent antioxidant, anti-inflammatory, anti-hepatotoxic, and anti-tyrosinase effects compared to positive references. Treatment of rats with the FTE at 2000 mg/kg/day for 28 consecutive days reversed CCl4-induced oxidative damage in hepatic tissues by lowering the levels of alanine aminotransferase by 69% and malondialdehyde by 90%. Our findings suggest that the FTE has the capacity to scavenge free radicals and can protect against oxidative stress induced by CCl4 intoxication. The docking results were consistent with our in vitro data, indicating the anti-tyrosinase potency of the principal catechins.

Full Text Available Abstract Background The role of free oxygen radicals in inflammatory conditions is well known. Free radicals cause lipid peroxidation of cellular membranes resulting in cell death. The purpose of this study was to investigate the levels of total anti-oxidant status (TAS, as a marker of anti-oxidant defense system and malondialdehyde (MDA, as a marker of oxidative stress, in the plasma of patients with acute appendicitis. Methods Fifty-one adult patients with a median age of 31 years who underwent operations with a preoperative diagnosis of acute appendicitis were included in this prospective study. Blood samples for C-reactive protein (CRP, MDA and TAS were collected preoperatively. Groups were compared by using the Mann-Whitney U test. Results There were 27 patients with acute phlagmenous appendicitis and 19 patients with advanced appendicitis (10 gangrenous and 9 perforated appendicitis, while 5 negative explorations were documented. No significant differences in WBC counts and MDA levels between groups were encountered. Plasma CRP was significantly higher in patients with perforated appendicitis, but not in the other groups. In advanced appendicitis group, TAS level was significantly lower than the other groups. On the other hand, plasma TAS level in acute phlagmenous appendicitis group was significantly higher. Conclusion A decrease in plasma total anti-oxidant capacity might be a predictor of the progression of inflammation to the perforation in acute appendicitis.

This study examined relationships between physical appearance concerns (fear of fat, body image disturbance; BIDQ), disgust, and anti-fat prejudice (dislike, blame), and tested whether disgust mediates relationships between physical appearance concerns and anti-fat prejudice. Participants (N=1649; age=28 years) provided demographic data and completed measures of anti-fat prejudice, tendency to feel disgust, and physical appearance concerns. Univariate, multivariate, and mediation analyses were conducted. Univariate and multivariate associations were found between fear of fat, BIDQ, disgust, and anti-fat prejudice for women. For women only, mediation analyses showed that disgust partially mediated relationships between physical appearance concerns and dislike of fat people. For men, univariate and multivariate relationships were found between fear of fat, and dislike and blame of fat people, but disgust was not related to anti-fat prejudice. Newer constructs centering on physical appearance concerns and disgust appear promising candidates for understanding anti-fat prejudice. Copyright © 2013 Elsevier Ltd. All rights reserved.

Legitimate Peripheral Participation as a Framework for Conversation Analytic Work in Second Language Learning

2009-03-01

Full Text Available Since its inception, Conversation Analysis (CA has become not only a framework and a set of methods for studying the generic machinery of talk-in-interaction but also a celebrated, qualitative method for studying a wealth of phenomena and exploring and testing concepts and hypotheses from numerous disciplines, including linguistics, psychology, anthropology and Second Language Acquisition (SLA. CA is often resorted to as the key to resolving knots and dead-ends in these neighboring disciplines. Despite the very interesting results that such work admittedly produces, it is too often not accompanied by focused considerations of how the specific concerns from one field match with the aims that CA procedures have been developed for and hence with the procedures themselves. This paper takes recent applications of CA to the study of SLA as a case in point. It discusses a whether CA can shed light on "learning" as commonly defined in SLA and b whether the resort to a particular model of learning (LAVE & WENGER, 1991, Legitimate Peripheral Participation (LPP helps overcoming some of the problems with which CA work in SLA is confronted. It is hoped that the specific discussions of problems involved in the project, CA-for-SLA, will contribute to the ongoing, general discussion of qualitative research methods and their prospects and problems.

The relationship between serum anti-Mullerian hormone (AMH) with vitamin D (25OH-D) and metabolic syndrome (MetS) risk was evaluated in healthy, late reproductive-age (35-49 years) women with regular menstrual cycles. Among the 291 participants (mean age = 42.5 years), most (76.6%, n = 223) were serum vitamin D insufficient (D were 2.04 ng/mL and 15.9 ng/mL, respectively. There was no correlation between AMH and 25OH-D after adjustment for age (r = -0.093, p = 0.113). Subjects with higher MetS score, higher waist circumference, and higher diastolic blood pressure had significantly higher serum AMH levels when adjusted for age, but the association attenuated when BMI was included. There was no significant correlation between MetS risk components with serum level of AMH or vitamin D. In conclusion, there was no association between AMH with serum 25OH-D or MetS risk factors in this population.

A “Mini-Epidemic” of anti-glomerular basement membrane disease: Clinical and epidemiological study

Full Text Available Acute glomerulonephritis due to anti-glomerular basement membrane (anti-GBM antibody disease is rare, estimated to occur in fewer than one case per million population and accounts for less than 20% of rapidly progressive glomerulonephritis. The prevalence among patients evaluated for potential glomerular disease is lower. It accounts for fewer than 3% of all kidney biopsies done with crescentic glomerulonephritis. Cases of anti-GBM disease occurring in a cluster have rarely been reported. All biopsy proven anti-GBM disease cases were collected from January 2015 to March 2015 at our Institute. All cases were analyzed for demographic and clinical profile, pathological findings, treatment received and for any common environmental antigenic source. A total of 11 new biopsy proven anti-GBM cases were seen within a span of three months. Age group varied from 17–80 years. Seven were males and four were females. All were dialysis dependent at presentation. Seven had active cellular crescents, and four had fibrocellular. Only one patient was a smoker and none had a history of exposure to any forms of hydrocarbons. The peak seen from January 2015 to March 2015 does not correlate with any of seasonal occurrence of infections in southern India. Although there was clustering of cases to southern territories of Karnataka state, no common etiological agents could be identified. No patient had any previous urological surgeries. All patients received methylprednisolone with plasmapheresis 5–7 sessions and cyclophosphamide. All 11 patients were dialysis dependent at the end of three months. We conclude anti-GBM disease cannot be regarded as a rare cause of renal failure and lung hemorrhage. The occurrence of such epidemic within a short period suggests a possible unidentified environmental factor like infection or occupational agents as inciting agents. Identification of such inciting agents could help us in instituting appropriate preventing measures.

Full Text Available The Colombian state is about to close one of the worst chapters in its history: the war against FARC (Revolutionary Armed Forces of Colombia that has lasted for more than five decades. After more than three years of discussions, the parties have settled on important agreements such as the de-escalation of the armed conflict and transitional justice mechanisms. It is thus time for the State to use constitutional and legal means to incorporate the agreements into the national legal system. President Juan Manuel Santos has called for a plebiscite as the means to legitimate the peace agreements. As a surprise to many, the plebiscite did not obtain the votes needed for its implementation, leaving it’s future in uncertainty. The government is now considering other alternatives, such as pass it through congress, call for an open council meeting and even call for a new plebiscite. The main aim of this article is to analyze the mechanisms of constitutional reform existing in the Colombian legal system to validate the Havana Talks. Some concepts, and constitutional and legal regulations will be studied and various mechanisms of citizen participation and constitutional reform will be contrasted that may help to achieve the government expectations with the peace process.

Feasibility studies of the anti pp→π circle e+e- electromagnetic channel at anti PANDA

Boucher, Jerome

Among all possible realizations of quark and antiquark assembly, the nucleon (the proton and the neutron) is the most stable of all hadrons and consequently has been the subject of intensive studies. Mass, shape, radius and more complex representations of its internal structure are measured since several decades using different probes. The proton (spin 1/2) is described by the electric G E and magnetic G M form factors which characterise its internal structure. The simplest way to measure the proton form factors consists in measuring the angular distribution of the electron-proton elastic scattering accessing the so-called Space-Like region where q 2 ≤0. Using the crossed channel anti pp e + e - , one accesses another kinematical region, the so-called Time-Like region where q 2 >0. However, due to the anti pp e + e - threshold q 2 th , only the kinematical domain q 2 >q 2 th > 0 is available. To access the unphysical region, one may use the anti pp→π circle e + e - reaction where the π circle takes away a part of the system energy allowing q 2 to be varied between q 2 th and almost 0. This thesis aims to show the feasibility of such measurements with the anti PANDA detector which will be installed on the new high intensity antiproton ring at the FAIR facility at Darmstadt. To describe the anti pp → π circle e + e - reaction, a Lagrangian based approach is developed. The 5-fold differential cross section is determined and related to linear combinations of hadronic tensors. Under the assumption of one nucleon exchange, the hadronic tensors are expressed in terms of the 2 complex proton electromagnetic form factors. An extraction method which provides an access to the proton electromagnetic form factor ratio R= vertical stroke G E vertical stroke / vertical stroke G M vertical stroke and for the first time in an unpolarized experiment to the cosine of the phase difference is developed. Such measurements have never been performed in the unphysical region up to

Recently, the incidence of acute hepatitis A has increased nationwide and is related to the low rate of IgG anti-HAV. This study compared the prevalence of IgG anti-HAV in two university hospitals located in a large city and in a small city including a rural region according to age, gender, and the year of diagnosis. IgG anti-HAV was measured in a total of 4299 patients, who visited Seoul or Guri Hanyang University Hospital between January 2002 and December 2006. The positive rates of the antibody in Seoul and Guri hospitals were 52.7% vs 57.1% in under the age of 1, 40.7% vs 42.2% in age of 1 to 4, 31.8% vs 30.3% in age of 5 to 9, 24.8% vs 27.1% in age of 10 to 14, 11.6% vs 18.2% in age of 15 to 19, 23.0% vs 20.3% in age of 20 to 24, 40.5% vs 42.9% in age of 25 to 29, 67.5% vs 75.0% in age of 30 to 34, 86.5% vs 88.1% in age of 35 to 39, 95.3% vs 93.6% in age of 40 to 44, 97.0% vs 98.7% in age of 45 to 49, and 98.5% vs 98.6% in patients who were more than 50, respectively. The positive rates of the antibody were not significantly different between two sites according to each age group and gender. The results confirmed the low rates of IgG anti-HAV, particularly in the ages of 10-24 that match the age group of recently increased incidence of acute hepatitis A nationwide. Therefore, measurement of the antibody and vaccination should be considered in this age group.

As the Framework Convention on Tobacco Control (FCTC) calls for public health awareness on tobacco use, mass media campaigns should be appropriately designed so as to maximize their effectiveness. In this methodological pilot study, 95 Greek adolescents (mean age 15 +/- 1.8 years), were shown seven different anti tobacco ads, and asked to rate the ad theme, message and emotional context on a 1-7 Likert scale. Health related ads were rated the highest, and as identified through the logistic regression analysis, adolescents who perceived an ad to be emotional or to have a clear message that was relevant to them, were more likely to rate the ad as more effective. The strong agreement between the above findings and the existing literature indicates the applicability of this pilot study's methodological approach.

Sean Cannady

2014-01-01

Full Text Available This article draws parallels between Tsar Nicholas I and current Russian President Vladimir Putin with respect to their use of nationalism to justify statist policies and political authoritarianism. Building upon insights by Alexander Gerschenkron about the economic development of “backwards” states, it argues that both Nicholas and Putin have rhetorically used Western concepts such as nationalism and democracy to legitimize their rule but have modified them to give them more statist content. Under Nicholas, this was exemplified in the tripartite (Orthodoxy, Autocracy, and Nationality Official Nationality policy. Putin has emphasized patriotism, power, and statism to justify centralization of power and authoritarian policies. Putin's policies and rhetoric are strong analogs to those of Nicholas. Ultimately, the goal of this paper is to explain state-inspired Russian nationalism and how it has been aligned with authoritarian politics, as well as specifying similarities between present and past in Russia.

Background/Aims The incidence of symptomatic hepatitis A reportedly increased among 20- to 40-year-old Korean during the late 2000s. Vaccination against hepatitis A was commenced in the late 1990s and was extended to children aged <10 years. In the present study we analyzed the changes in the seroprevalence of IgG anti-hepatitis A virus (HAV) over the past 13 years. Methods Overall, 4903 subjects who visited our hospital between January 2001 and December 2013 were studied. The seroprevalence of IgG anti-HAV was analyzed according to age and sex. In addition, the seroprevalence of IgG anti-HAV was compared among 12 age groups and among the following time periods: early 2000s (2001-2003), mid-to-late 2000s (2006-2008), and early 2010s (2011-2013). The chi-square test for trend was used for statistical analysis. Results The seroprevalence of IgG anti-HAV did not differ significantly between the sexes. Furthermore, compared to the seroprevalence of IgG anti-HAV in the early 2000s and mid-to-late 2000s, that in the early 2010s was markedly increased among individuals aged 1-14 years and decreased among those aged 25-44 years (P<0.01). We also found that the seroprevalence of IgG anti-HAV in individuals aged 25-44 years in the early 2010s was lower than that in the early 2000s and mid-to-late 2000s. Conclusions The number of symptomatic HAV infection cases in Korea is decreasing, but the seroprevalence of IgG anti-HAV is low in the active population. PMID:25032182

Citrullination as well as anti-citrullinated protein/peptide antibodies (ACPA) have been implicated in the pathogenesis of rheumatoid arthritis (RA). While ACPAs are specific and sensitive markers for RA, there have been hardly any reports regarding ACPAs in ankylosing spondylitis (AS). The possible role of antibodies to Mycobacterial 65 kDa heat shock protein (hsp65) has not been characterized in AS. As new laboratory biomarkers of AS are needed, we investigated the prevalence of anti-mutated citrullinated vimentin (MCV) and anti-hsp65 antibodies in AS. Altogether 43 AS and 44 healthy controls were included in the study. Anti-MCV and anti-hsp65 were determined in sera by commercial and in-house ELISA, respectively. Serum autoantibody levels were correlated with ESR, CRP, HLA-B27 status, smoking habits, pain intensity, BASDAI, BASFI and BASMI indices. Patients with AS had significantly higher serum anti-MCV levels (17.3 U/mL, range: 8.3-31.5 U/mL) in comparison to healthy subjects (8.9 U/mL, range: 5.4-13.3 U/mL) (p20 U/mL). The mean anti-hsp65 concentration in AS sera was 124.8 AU/mL (range: 27.2-1000 AU/mL), while controls exerted significantly lower anti-hsp65 levels (mean: 51.8 AU/mL; range: 22.5-88.5 AU/mL) (p<0.001). Correlation analysis revealed that both anti-MCV positivity (r=0.613; p=0.012) and absolute serum anti-MCV levels (r=0.553; p=0.021) correlated with anti-hsp65 levels. Anti-MCV positivity also correlated with ESR (r=0.437; p=0.03). Anti-MCV and anti-hsp65 may be novel biomarkers in AS. Copyright © 2011. Published by Elsevier SAS.

Hybrid mesons (Q anti Qg) in N anti N annihilation

Dover, C.B.; Gutsche, T.; Faessler, A.

1993-09-01

N anti N annihilation reactions provide exciting possibilities to study mesonic resonances beyond the usual Q anti Q spectrum. Particularly the search for Q anti Qg mesons containing an explicit dynamical excitation of the gluon field is not promising, since hybrids are predicted to display unique features: exotic quantum numbers (J πC ) and dynamical selection rules for their decay modes. The authors have investigated the possibility of producing hybrids from p anti p atomic states in reactions of the type N anti N(L= 0,1) → π + Q anti Qg. Production rates for hybrid mesons are found to display a strong dependence on the quantum numbers and kinematical factors associated with the transition. The dependence on the orbital angular momentum L of the p anti p atomic state, accessible in p anti p annihilation at rest, would provide a striking signature for the production of hybrids. In estimating branching ratios for the formation of Q anti Qg hybrid mesons in N anti N annihilation reactions at rest, the authors have employed a microscopic model with constituent quarks and gluons in analogy to the annihilation model for the production of Q anti Q mesons

Forensic age estimation (FAE) was conducted using a multifactorial method on thirteen Somali detainees claiming juvenile status during the anti-piracy trials of the Seychelles Supreme Court in 2014/2015. A multidisciplinary team, comprising of four of the authors covering specialties in forensic medicine, forensic odontology and radiology, conducted the FAE using a five-stage protocol. Each detainee was interviewed with an interpreter and examined for disorders affecting dental/skeletal development and for assessment of genital development through Tanner staging. Dental maturity was assessed clinically and radiologically. Eruption stage was assessed using Olze et al. and mandibular third-molar maturity was assessed using Demirjian's classification. Skeletal maturity was assessed from hand-wrist X-rays according to Greulich & Pyle and from CT-clavicle according to Kellinghaus et al. and Schultz et al. Interpretation of findings was done using reference population data from similar ethnic and social backgrounds wherever possible. Final age-ranges were calculated by combining dental and clavicle maturity stages using the regression formula developed by Bassed et al. followed by a 10% correction factor. The team later testified on their findings under cross-examination. The protocol adopted by the authors increased the scientific validity of the findings and was useful in addressing cross-examination queries on exclusion of developmental disorders, ethnic/socioeconomic variability and maintaining chain of custody. Unforeseen jurisdictional and practical limitations were experienced but did not affect the outcome. Combining dental and clavicle developmental data provided the court with a much clearer picture on the likelihood of the detainees' juvenile status which emphasizes the importance of conducting more population studies using combinations of different developmental sites. The authors note that available reference data is mostly from affluent populations whereas

Full Text Available In order to realize low-frequency vibration isolation, a novel geometric anti-spring isolator consisting of several cantilever blade springs are developed in this paper. The optimal design parameters of the geometric anti-spring isolator for different nonlinear geometric parameters are theoretically obtained. The transmissibility characteristic of the geometric anti-spring isolator is investigated through mathematical simulation. A geometric anti-spring isolator with a nonlinear geometric parameter of 0.92 is designed and its vibration isolation performance and nonlinearity characteristic is experimentally studied. The experiment results show that the designed isolator has good low-frequency vibration isolation performance, of which the initial isolation frequency is less than 3.6 Hz when the load weight is 21 kg. The jump phenomena of the response of the isolator under linear frequency sweep excitation are observed, and this result demonstrates that the geometric anti-spring isolator has a complex nonlinearity characteristics with the increment of excitation amplitude. This research work provides a theoretical and experimental basis for the application of the nonlinear geometric anti-spring low-frequency passive vibration isolation technology in engineering practice.

Analyse the clinical profile, associated tumour types, and response to treatment of paraneoplastic neurological syndromes associated with antibodies against Ma proteins. A retrospective study of patients with antibodies against Ma proteins identified in a neuroimmunology laboratory of reference. Of the 32 patients identified, 20 showed reactivity against Ma2 only (anti-Ma2 antibodies), 11 against Ma1 and Ma2 (anti-Ma antibodies), and 1 with reactivity against Ma1 only (anti-Ma1 antibodies). The most common clinical presentations were limbic encephalopathy, diencephalic dysfunction, or brainstem encephalopathy, frequently appearing as a combination of these features. Three patients had isolated cerebellar dysfunction with anti-Ma antibodies, and 2 exhibited peripheral nervous system syndrome with anti-Ma2 antibodies. Testicular tumours were the most common neoplasms (40%) in the anti-Ma2 cases. In the group associated with anti-Ma1 antibodies, the most common were lung tumours (36%), followed by testicular tumours. All idiopathic cases were reactive to Ma2. The clinical outcome was significantly better in the anti-Ma2 group. The patient with anti-Ma1 presented with limbic encephalitis and brainstem dysfunction associated with lymphoepithelioma of the bladder. Specifically determining the different reactivities of anti-Ma protein antibodies in order to differentiate between Ma1 and Ma2 antibodies is important because anti-Ma2-associated paraneoplastic syndromes have a better outcome. Lastly, this study is the first to confirm that there may be cases that react exclusively to antibodies against Ma1. Copyright © 2016 Sociedad Española de Neurología.

In Brazil, there have been no previous studies of Toxoplasma gondii infection in sickle cell anemia patients and carriers of severe forms of beta-thalassemia. This study evaluated T. gondii infection in patients with beta-hemoglobinopathies. A total of 158 samples, 77 (48.7%) men and 81 (51.3%) women, were evaluated. Three groups were formed: G1 (85 patients with sickle cell disease); G2 (11 patients with homozygous beta-thalassemia; G3 (62 patients with heterozygous beta-thalassemia). ELISA was employed to identify anti-T. gondii IgM and IgG antibodies, and molecular analysis was performed to determine beta-hemoglobin mutations. Fisher's exact test was used to compare frequencies of anti-T. gondii IgM and IgG antibodies in respect to gender and age. Anti-T. gondii IgG antibodies were found in 43.5% of individuals in G1, 18.1% in G2 and 50% in G3. All samples from G1 and G2 were seronegative for anti-T. gondii IgM antibodies, but 3.2% from G3 were seropositive. Considering anti-T. gondii IgG antibodies, no statistical significant differences were found between these groups nor in seroprevalence between genders within each group. Despite this, comparisons of the mean ages between G1, G2 and G3 were statistically significant (G2 vs. G1: p value = 0.0001; G3 vs. G1: p-value <0.0001; G3 vs. G2: p-value = 0.0001). A comparison by age of patients with sickle cell anemia showed a trend of lower risk of infection among younger individuals. Therefore, this study demonstrates that T. gondii infection occurs in patients with beta-thalassemia and sickle cell anemia in Brazil as seen by the presence of anti-T. gondii IgM and IgG antibodies.

Diabetes is a metabolic disorder associated with either improper functioning of the beta-cells or wherein cells fail to use insulin properly. Insulin, the principal hormone regulates uptake of glucose from the blood into most of the cells except central nervous system. Therefore, deficiency of insulin or the insensitivity of its receptors plays a key role in all forms of diabetes. In the present work, attempt has been made to find out plant sources which show anti hyperglycaemic activity (AhG) (i.e. compounds that bring down the blood glucose level in the body). Ayurvedic plants showing AhG activity formed the basis of our study by using the platform of Computer Aided Drug Designing (CADD). Among 600 plants showing AhG activity, 500 compounds were selected and screened, out of which 243 compounds showed drug likeness property that can be used as therapeutic ligand/drug. Initial screening of such compounds was done based on their drug likeness or biochemical properties. Dynamic interaction of these molecules was captured through Protein-Ligand study. It also gave an insight of the binding pockets involved. Bench marking of all the parameters were done using the diabetic inhibitor drug, Glipizide. Pharmacokinetic studies of the compounds such as Aloins, Capparisine, Funiculosin and Rhein exhibited less toxicity on various levels of the body. As a conclusion these ligands can lay a foundation for a better anti-diabetic therapy. AhG - Anti hyperglycaemic, CADD - Computer Aided Drug Designing.

The levels of anti-HPV16/18 and anti-HPV31/33/35/45/52/58 antibodies among AS04-adjuvanted HPV16/18 vaccinated and non-vaccinated Ugandan girls aged 10-16 years.

Data on Human Papilloma virus (HPV) vaccine immune response in sub-Saharan Africa is still sparse yet such knowledge is critical for optimal implementation and monitoring of HPV vaccines. Our primary objective was to evaluate levels of anti-HPV-16/18 antibodies and six other 'high risk' HPV (hrHPV) types among the vaccinated and unvaccinated Ugandan girls. We conducted a cross sectional study among AS04-adjuvanted HPV-16/18 vaccinated and unvaccinated school girls aged 10-16 years in Western Uganda using purposive sampling. The vaccinated girls were at 18 months post vaccination. After consenting and assenting, data was collected using interviewer administered questionnaires for demographics and sexual history. Blood was drawn from which serum samples were analysed by the multiplex HPV serology technology to determine anti-HPV antibody levels to HPV-16/18 and six other hrHPV types (31, 33, 35, 45, 52 and 58). The antibody levels were expressed as Median Fluorescent Intensity (MFI). A total of 207 vaccinated [mean age 13.1 years (SD 1.5); range 10-16 years] and 197 unvaccinated girls [mean age 13.6 years (SD 1.3); range 10-16 years] participated in the study. Sexual activity was self reported among 14/207 (6.8%) vaccinated and 5/197 (2.5%) unvaccinated girls. The MFI levels for HPV-16 and HPV-18 were 15 and 20 times higher respectively in the vaccinated girls than in the unvaccinated girls. HPV-16 mean MFI level was 4691(SD 1812; 95% CI: 4438-4958) among the vaccinated compared to 218 (SD 685; 95% CI: 190-252) among the unvaccinated girls. For HPV-18 the mean MFI level was 1615 (SD 1326; 95% CI: 1470-1776) among the vaccinated compared to MFI 103 (SD 506; 95% CI: 88 -121) among unvaccinated girls. In addition antibody levels to non vaccine hrHPV types (31, 33, 35, 45, 52 and 58) were all significantly higher in the vaccinated group than in the unvaccinated group (plevel of antibodies to HPV-16/18 and other non-vaccine hrHPV types compared to the unvaccinated girls

In Japan, the major transfusion-associated disease is non-A, non-B hepatitis. We studied the relationship between transfusion history and blood donor antibodies to hepatitis C virus (HCV). The positive rate of antibodies to the HCV nonstructural protein (c100-3) depended on age and the time elapsed since transfusion. The anti-c100-3 ratio for subjects with transfusions made prior to 20 years ago was high. One quarter century ago, a change occurred in national blood policy from paid to non-paid voluntary donations. We also have studied the anti-HCV positive rate among donors with prior transfusion using a second generation HCV test kit which includes anti-HCV core antibody detection. The anti-HCV positive rate for the second generation test was higher than that for the anti-c100-3 test. Introduction of the second generation test is therefore more useful in screening than the anti-c100-3 test for blood programs.

In this work, we study systematically the mass splittings of the qq anti Q anti Q (q = u, d, s and Q = c, b) tetraquark states with the color-magnetic interaction by considering color mixing effects and estimate roughly their masses. We find that the color mixing effect is relatively important for the J{sup P} = 0{sup +} states and possible stable tetraquarks exist in the nn anti Q anti Q (n = u, d) and ns anti Q anti Q systems either with J = 0 or with J = 1. Possible decay patterns of the tetraquarks are briefly discussed. (orig.)

A Numerical Study of Anti-Vortex Film Cooling Designs at High Blowing Ratio

Heidmann, James D.

2008-01-01

A concept for mitigating the adverse effects of jet vorticity and liftoff at high blowing ratios for turbine film cooling flows has been developed and studied at NASA Glenn Research Center. This "anti-vortex" film cooling concept proposes the addition of two branched holes from each primary hole in order to produce a vorticity counter to the detrimental kidney vortices from the main jet. These vortices typically entrain hot freestream gas and are associated with jet separation from the turbine blade surface. The anti-vortex design is unique in that it requires only easily machinable round holes, unlike shaped film cooling holes and other advanced concepts. The anti-vortex film cooling hole concept has been modeled computationally for a single row of 30deg angled holes on a flat surface using the 3D Navier-Stokes solver Glenn-HT. A modification of the anti-vortex concept whereby the branched holes exit adjacent to the main hole has been studied computationally for blowing ratios of 1.0 and 2.0 and at density ratios of 1.0 and 2.0. This modified concept was selected because it has shown the most promise in recent experimental studies. The computational results show that the modified design improves the film cooling effectiveness relative to the round hole baseline and previous anti-vortex cases, in confirmation of the experimental studies.

Corn silk is a well-known ingredient frequently used in traditional Chinese herbal medicines. This study was designed to evaluate the anti-diabetic, anti-oxidant and anti-hyperlipidemic activities of crude flavonoids extracted from corn silk (CSFs) on streptozotocin (STZ)-induced diabetic mice. The results revealed that treatment with 300 mg/kg or 500 mg/kg of CSFs significantly reduced the body weight loss, water consumption, and especially the blood glucose (BG) concentration of diabetic mice, which indicated their potential anti-diabetic activities. Serum total superoxide dismutase (SOD) and malondialdehyde (MDA) assays were also performed to evaluate the anti-oxidant effects. Besides, several serum lipid values including total cholesterol (TC), triacylglycerol (TG), low density lipoprotein cholesterol (LDL-C) were reduced and the high density lipoprotein cholesterol level (HDL-C) was increased. The anti-diabetic, anti-oxidant and anti-hyperlipidemic effect of the CSFs suggest a potential therapeutic treatment for diabetic conditions.

Full Text Available The Unani eye drop is an ophthalmic formulation prepared for its beneficial effects in the inflammatory and allergic conditions of the eyes. In the present study, the Unani eye drop formulation was prepared and investigated for its anti-inflammatory and antihistaminic activity, using in vivo and in vitro experimental models respectively. The Unani eye drop formulation exhibited significant anti-inflammatory activity in turpentine liniment-induced ocular inflammation in rabbits. The preparation also showed antihistaminic activity in isolated guinea-pig ileum. The anti-inflammatory and antihistaminic activity of eye drop may be due to presence of active ingredients in the formulation. Although there are many drugs in Unani repository which are mentioned in classical books or used in Unani clinical practice effectively in treatment of eye diseases by various Unani physicians. Inspite of the availability of vast literature, there is a dearth of commercial Unani ocular preparations. So, keeping this in mind, the eye drop formulation was prepared and its anti-inflammatory and antihistaminic activity was carried out in animal models. Thus, in view of the importance of alternative anti-inflammatory and antiallergic drugs, it becomes imperative to bring these indigenous drugs to the front foot and evaluate their activities.

Measurements of differential and integrated cross sections as well as final state polarizations for the anti p p → anti Λ Λ reaction are presented. The reaction was studied at two incident antiproton momenta (1476.5 MeV/c and 1507.5 MeV/c) corresponding to total center of mass energies of 15.5 MeV and 26.4 MeV above the reaction threshold. The trajectories of charged decay products of the anti Λ and Λ were observed in a multiwire proportional chamber and in two sets of drift chambers. The data were analyzed with a computer program which reconstructed anti p p → anti Λ Λ → anti p π + pπ - events and performed kinematic fitting. The results are compared to several recent meson exchange calculations, and a one-gluon exchange calculation. The experiment was performed at the Low Energy Antiproton Ring (LEAR) at CERN. The data presented represent the first results of the PS185 collaboration's study of the threshold production of hyperon-antihyperon states

From performance to performativity: The legitimization of US security contracting and its consequences.

Science.gov (United States)

Krahmann, Elke

2017-12-01

Discussions about the legitimacy of private security companies (PSCs) in multilateral military interventions abound. This article looks at how the United States has sought to legitimize the outsourcing of security services to PSCs through performance-based contracting and performance assessments. Both mechanisms aim to demonstrate the effective provision of publicly desirable outcomes. However, the immaterial and socially constructed nature of security presents major problems for performance assessments in terms of observable and measurable outcomes. Performance has therefore given way to performativity - that is, the repetitive enactment of particular forms of behaviour and capabilities that are simply equated with security as an outcome. The implications of this development for the ways in which security has been conceptualized, implemented and experienced within US interventions have been profound. Ironically, the concern with performance has not encouraged PSCs to pay increased attention to their impacts on security environments and civilian populations, but has fostered a preoccupation with activities and measurable capabilities that can be easily assessed by government auditors.

Full Text Available INTRODUCTION: Epstein-Barr virus exposure appears to be an environmental trigger for rheumatoid arthritis that interacts with other risk factors. Relationships among anti-cyclic citrullinated peptide antibodies, the shared epitope, and smoking status have been observed in patients with rheumatoid arthritis from different populations. OBJECTIVE: To perform an association analysis of anti-Epstein-Barr nuclear antigen-1 antibodies, anti-cyclic citrullinated peptide antibodies, the shared epitope, and smoking status in Brazilian patients with rheumatoid arthritis. METHODS: In a case-control study, 140 rheumatoid arthritis patients and 143 healthy volunteers who were matched for age, sex, and ethnicity were recruited. Anti-Epstein-Barr nuclear antigen-1 antibodies and anti-cyclic citrullinated peptide antibodies were examined using an enzyme-linked immunosorbent assay, and shared epitope alleles were identified by genotyping. Smoking information was collected from all subjects. A comparative analysis of anti-Epstein-Barr nuclear antigen-1 antibodies, anti-cyclic citrullinated peptide antibodies, the shared epitope, and smoking status was performed in the patient group. Logistic regression analysis models were used to analyze the risk of rheumatoid arthritis. RESULTS: Anti-Epstein-Barr nuclear antigen-1 antibodies were not associated with anti-cyclic citrullinated peptide antibodies, shared epitope alleles, or smoking status. Anti-cyclic citrullinated peptide antibody positivity was significantly higher in smoking patients with shared epitope alleles (OR = 3.82. In a multivariate logistic regression analysis using stepwise selection, only anti-cyclic citrullinated peptide antibodies were found to be independently associated with rheumatoid arthritis (OR = 247.9. CONCLUSION: Anti-Epstein-Barr nuclear antigen-1 antibodies did not increase the risk of rheumatoid arthritis and were not associated with the rheumatoid arthritis risk factors studied. Smoking

Campylobacter jejuni is the leading cause of acute bacterial infectious diarrhea in humans. Unlike in humans, C. jejuni is a commensal within the avian host. Heavily colonized chickens often fail to display intestinal disease, and no cellular attachment or invasion has been demonstrated in-vivo. Recently, researchers have shown that the reason for the attenuation of C. jejuni virulence may be attributed to the presence of chicken intestinal mucus and more specifically chicken mucin. Since mucins are heavily glycosylated molecules this observation would suggest that glycan-based compounds may act as anti-infectives against C. jejuni. Considering this, we have investigated naturally sourced foods for potential anti-infective glycans. Bovine colostrum rich in neutral and acidic oligosaccharides has been identified as a potential source of anti-infective glycans. In this study, we tested oligosaccharides isolated and purified from the colostrum of Holstein Friesian cows for anti-infective activity against a highly invasive strain of C. jejuni. During our initial studies we structurally defined 37 bovine colostrum oligosaccharides (BCO) by HILIC-HPLC coupled with exoglycosidase digests and off-line mass spectroscopy, and demonstrated the ability of C. jejuni to bind to some of these structures, in-vitro. We also examined the effect of BCO on C. jejuni adhesion to, invasion of and translocation of HT-29 cells. BCO dramatically reduced the cellular invasion and translocation of C. jejuni, in a concentration dependent manner. Periodate treatment of the BCO prior to inhibition studies resulted in a loss of the anti-infective activity of the glycans suggesting a direct oligosaccharide-bacterial interaction. This was confirmed when the BCO completely prevented C. jejuni binding to chicken intestinal mucin, in-vitro. This study builds a strong case for the inclusion of oligosaccharides sourced from cow's milk in functional foods. However, it is only through further

From Subordination to Hegemony On the Epistemological Legitimation of Mathematics in Natural Philosophy of XVII Century

Directory of Open Access Journals (Sweden)

Felipe Ochoa

2013-12-01

Full Text Available This article analyzes the epistemological legitimation of mathematics in natural philosophy in the seventeenth century. In the Renaissance it was claimed that mathematics does not meet the Aristotelian criteria of scientificity, and that it did not explain the efficient and final causes. So, its critics, inspired by the Aristotelian tradition, rejected the first attempts to mathematize natural philosophy. The epistemological conditions involved in the debate are examined on the scientific nature of mathematics and its relevance to natural philosophy. A historiographical tour of the mathematization of nature is made to provide new weighing elements with respect to a historically and philosophically more conceptual characterization of the emergence of modern science.

Full Text Available The paper is devoted to the study of representations of the ideals and anti-ideals in secondary and high schools students. The study is important due to connection with the peculiarities of modern adolescent socialization in the context of contemporary social cultural realities. Shaping the world view in students is significantly influenced by the choice of values and the social role model. In this regard, the aim of this study was to examine gender and age dynamics of different groups of personalities related to the politics and spiritual culture in the structure of ideals and anti-idials in modern adolescents. Aggravation of the internal and external political situation, politically-oriented media content and society as a whole, the introduction of information technologies in various spheres of life, the «western» background of cultural values and information environment, the shift of sex-role identification has a significant influence on gender-specific and age-specific dynamics and significance of different groups of personalities in the structure of ideals and anti-idials in modern adolescents are based on the data of content analysis and a questionnaire survey of 2,273 students, grades 5-11. The features of the structure of ideals and anti-idials of boys and girls, which are formed under the influence of gender identification are characterized. The analysis of the students’ groups of ideals and anti-idials is held depending on their belonging to the Russian and foreign cultures. The students’ representations of the ideals and anti-idials are of a mixed structure, dominated by the personalities of the real people in comparison with the images (characters of works of literature, cinema, cartoons. The sphere of political culture and ideology (politicians, historical figures that presents male personalities is significant for boys. For girls, besides politics, the literary field (writers and movie actors is more important, where the

ASM-3 acid sphingomyelinase functions as a positive regulator of the DAF-2/AGE-1 signaling pathway and serves as a novel anti-aging target.

Yongsoon Kim

Full Text Available In C. elegans, the highly conserved DAF-2/insulin/insulin-like growth factor 1 receptor signaling (IIS pathway regulates longevity, metabolism, reproduction and development. In mammals, acid sphingomyelinase (ASM is an enzyme that hydrolyzes sphingomyelin to produce ceramide. ASM has been implicated in CD95 death receptor signaling under certain stress conditions. However, the involvement of ASM in growth factor receptor signaling under physiological conditions is not known. Here, we report that in vivo ASM functions as a positive regulator of the DAF-2/IIS pathway in C. elegans. We have shown that inactivation of asm-3 extends animal lifespan and promotes dauer arrest, an alternative developmental process. A significant cooperative effect on lifespan is observed between asm-3 deficiency and loss-of-function alleles of the age-1/PI 3-kinase, with the asm-3; age-1 double mutant animals having a mean lifespan 259% greater than that of the wild-type animals. The lifespan extension phenotypes caused by the loss of asm-3 are dependent on the functions of daf-16/FOXO and daf-18/PTEN. We have demonstrated that inactivation of asm-3 causes nuclear translocation of DAF-16::GFP protein, up-regulates endogenous DAF-16 protein levels and activates the downstream targeting genes of DAF-16. Together, our findings reveal a novel role of asm-3 in regulation of lifespan and diapause by modulating IIS pathway. Importantly, we have found that two drugs known to inhibit mammalian ASM activities, desipramine and clomipramine, markedly extend the lifespan of wild-type animals, in a manner similar to that achieved by genetic inactivation of the asm genes. Our studies illustrate a novel strategy of anti-aging by targeting ASM, which may potentially be extended to mammals.

In C. elegans, the highly conserved DAF-2/insulin/insulin-like growth factor 1 receptor signaling (IIS) pathway regulates longevity, metabolism, reproduction and development. In mammals, acid sphingomyelinase (ASM) is an enzyme that hydrolyzes sphingomyelin to produce ceramide. ASM has been implicated in CD95 death receptor signaling under certain stress conditions. However, the involvement of ASM in growth factor receptor signaling under physiological conditions is not known. Here, we report that in vivo ASM functions as a positive regulator of the DAF-2/IIS pathway in C. elegans. We have shown that inactivation of asm-3 extends animal lifespan and promotes dauer arrest, an alternative developmental process. A significant cooperative effect on lifespan is observed between asm-3 deficiency and loss-of-function alleles of the age-1/PI 3-kinase, with the asm-3; age-1 double mutant animals having a mean lifespan 259% greater than that of the wild-type animals. The lifespan extension phenotypes caused by the loss of asm-3 are dependent on the functions of daf-16/FOXO and daf-18/PTEN. We have demonstrated that inactivation of asm-3 causes nuclear translocation of DAF-16::GFP protein, up-regulates endogenous DAF-16 protein levels and activates the downstream targeting genes of DAF-16. Together, our findings reveal a novel role of asm-3 in regulation of lifespan and diapause by modulating IIS pathway. Importantly, we have found that two drugs known to inhibit mammalian ASM activities, desipramine and clomipramine, markedly extend the lifespan of wild-type animals, in a manner similar to that achieved by genetic inactivation of the asm genes. Our studies illustrate a novel strategy of anti-aging by targeting ASM, which may potentially be extended to mammals. PMID:23049887

Full Text Available OBJECTIVE: Nonimmune pregnant women are at risk of developing congenital rubella syndrome and measles complications. We aimed to identify pregnant women susceptible to rubella or measles in order to determine the need for immunity screening and supplemental immunization in women of childbearing age. METHOD: This seroprevalence survey was conducted by convenience sampling in obstetric hospitals affiliated with Shiraz University of Medical Sciences (southern Iran. Serum IgG levels were measured by ELISA. RESULT: Mean age of the 175 pregnant women was 27.3±5.3 (range 16 to 42 years. The geometric mean concentration of anti-rubella IgG was 14.9 IU/mL (CI 95%,14.1-15.5, and that of anti-measles IgG was 13.8 IU/mL (CI 95%, 13-14.5. One hundred sixty-eight women (96% had a protective serologic level (>11 IU/mL of IgG against rubella, and 143 (81.7% had a protective level against measles. Except for a significant inverse correlation that was showed by univariate analysis between anti-rubella IgG and the women's age (P = 0.01, immunity did not correlate with demographic or obstetric characteristics or medical history. There was no significant correlation between anti-rubella and anti-measles IgG levels (P = 0.25. CONCLUSION: Nearly a decade after Iran's nationwide measles-rubella vaccination campaign for the population aged 5-25 years, most pregnant women up to 34 years of age had humoral immunity against rubella. We recommend rubella immunity screening or catch-up immunization for women older than 35 years who wish to become pregnant, and measles immunity screening and appropriate vaccination for all women of childbearing age.

Increasing bilateral gluteus medius co-activation has been identified as one of the most important factors in developing low back pain due to prolonged standing in healthy people. This study aims to investigate the impact of an anti-fatigue mat on the bilateral gluteus medius co-activation pattern and to report the low back pain subjectively in 2 different standing positions on the normal rigid surface and on the anti-fatigue mat. While carrying out an easy simulated profession, 16 participants who had no low back pain background were requested to stand for 2 h in each position, with and without using the anti-fatigue floor mat, respectively. At the beginning of standing process and at every 15 min until the time of 120 min lapses, electric activities for the bilateral gluteus medius co-activation and subjective pain level in low back area were collected by the surface electromyogeraphy (EMG) and the visual analogue scale (VAS), respectively in each position. The obtained findings revealed that the anti-fatigue mat significantly decreased subjective pain level in low back area among 15 participants (p 0.05). The findings obtained under this study related to the impact of the anti-fatigue mat upon the low back pain based on the increase of > 10 mm on the VAS threshold, which showed that this intervention had no significant impact upon decreasing the number of patients suffering from the low back pain and also minimizing the bilateral gluteus medius co-activation in both pain developer groups (p > 0.05). However, 73% of the participants preferred to apply it. It seems that the anti-fatigue mat may be useful in reducing the low back pain although it objectively didn't significantly change the gluteus medius co-activation pattern related to the low back pain.

2011-01-01

Full Text Available Toxoplasma gondii infects humans through the gastrointestinal tract (GIT, which elicits humoral immune response with specific antibodies. The expression of the ABO blood group glycoconjugates also occurs in this same system and may influence the human susceptibility of infection by T. gondii. The aim of the present study was to investigate the association between ABO blood group phenotypes and the presence of anti-T. gondii antibodies. Data - including age, results of serology tests for T. gondii infection and ABO blood group phenotypes - were assembled from the medical records of 1,006 pregnant women attended in the Base Hospital of the Medical School of São José do Rio Preto, Brazil, between 2001 and 2004. The chi-square test was used to compare the results with the level of significance set at 5%. Of the studied cases, 64.1% (645/1006 and 35.9% (391/1006 presented respectively positive and negative serology tests for anti-T. gondii antibodies. The mean age of those who tested positive was higher than those with negative serology tests (p = 0.0004. The frequencies of ABO blood group phenotypes were similar in those with and without anti-T. gondii antibodies (p = 0.35. In conclusion, the ABO blood group system is not associated with the presence or absence of anti-T. gondii antibodies.

Wilkinson, Blair

2016-05-01

This article examines how university corporate security (UCS) services engage in legitimation work in their attempts to make their university communities (i.e., faculty, staff, students) and political masters (i.e., university administrators, boards of governors, senators) believe that they are honest, trustworthy, and caring and have authority that should be deferred to. This is accomplished through the analysis of interview and observational data collected as part of a research project exploring UCS services at five Canadian universities and an examination of how UCS services at 14 Canadian universities communicate using the social media service Twitter. These UCS services were found to primarily use Twitter for the purposes of soliciting or requesting information and for networking. In communicating through Twitter, UCS services engage in public legitimation work in which they make claims about and attempt to demonstrate their expertise, authority, and accountability. This article argues that both UCS services' particular legitimacy problem (i.e., their possession of both private and public attributes) and the interactive nature of public legitimation work create tensions that may serve to disrupt UCS services' ability to attain legitimacy. Cet article examine la manière dont les services de sécurité d'entreprise à l'université (SEU) s'engagent à légitimer leurs tentatives de persuader leurs communautés universitaires (c'est-à-dire le corps professoral, le personnel et les étudiants) ainsi que la haute administration (c'est-à-dire les administrateurs de l'université, le conseil des gouverneurs et les sénateurs) qu'ils sont honnêtes, attentifs, dignes de confiance, et qu'ils possèdent un niveau d'autorité auquel quiconque devrait se référer. Ceci sera accompli en analysant un corpus d'entrevues et d'observations dans le cadre d'un projet de recherche examinant les services de type SEU dans cinq universités canadiennes, ainsi qu'une étude sur

Legitimately seeking differences: The case of climate change strategies

Energy Technology Data Exchange (ETDEWEB)

Bui, B.; Fowler, C. [Victoria Univ. of Wellington (New Zealand)

2009-07-01

In 2002, the New Zealand Government announced its intention to introduce a carbon tax as part of its response to climate change. Following the review of New Zealand climate change policies, the proposed carbon tax was ruled out in 2005 and other measures were investigated. In October 2007, the government announced its new climate change policy package, a fundamental part of which is the domestic cap-and-trade Emissions Trading Scheme (ETS). The scheme is currently being revised by the Government, with a report due August 2009. The government's climate change policy and the ETS in particular, represent significant changes in regulatory and societal expectations of the way in which businesses will account for the impact of their carbon emissions on the natural environment. The New Zealand electricity generators are among the most heavily impacted by the Government's climate change policy due to the scale of carbon emissions from electricity generation. This study utilizes institutional theory and the concept of legitimate differentiation, using a resource-based view, to examine and explain the changes in the electricity generators' carbon-strategy related environmental management and reporting practices as a result of regulatory, societal and financial pressures arising from the Government's climate change policy as it changed between 2002 and 2008. A study of organizations' reactions to climate change regulations is timely because the phenomenon of changing regulation is worldwide and far-reaching in scale. As such, the findings from a New Zealand study of electricity companies are releavant to many countries and organizations. Two generators that are among the firms with highest levels of carbon emissions in the New Zealand electricity industry (NZEI) are selected for in-depth analysis. Each company is first analyzed longitudinally (2001-2008) to discern changes in their internal environmental structures, systems and strategies to account

Prevalence of cytomegalovirus (CMV) infection is 90-100% in developing countries; however, the kinetics of anti-CMV IgG in infants remains elusive. Sera from 112 mother-newborn pairs and longitudinal samples from 41 infants up to 2-year old were tested for anti-CMV IgG and IgM. Additionally, samples from 837 healthy children were included. Of 112 mothers, 108 (96.4%) were anti-CMV IgG positive; their 108 newborns were also seropositive. In a 2-year follow-up among 40 infants of positive mothers, anti-CMV IgG level in 8 individuals decreased with time and became undetectable by age of 3.5-8 months, and that in 32 others decreased at 1- and 3.5-month old, and then increased. Based on the positive IgM, rising IgG levels, and low anti-CMV IgG avidity index, 76.7% of the primary infections were demonstrated to occur during 1-3.5 months of age. The overall seroprevalence of anti-CMV in 837 children was 82.4%, which was generally constant from 2 to 8 years old (χ2 = 3.150, p = 0.790). The maternally acquired anti-CMV IgG in infants disappears before 8-month old. Primary CMV infection in Chinese children mostly occurs during 1-3.5 months of age. Whether the relatively lower seroprevalence of anti-CMV in Chinese children found in this survey may reflect the positive rate in child-bearing age women in the future remains to be further studied.

The use of essential oils (EOs) and their components is known since long in traditional medicine and aromatherapy for the management of various diseases, and is further increased in the recent times. The neuroprotective and anti-aging potentials of EOs and their possible mechanism of actions were evaluated by numerous researchers around the globe. Several clinically important EOs and their components from Nigella sativa , Acorus gramineus, Lavandula angustifolia, Eucalyptus globulus, Mentha piperita, Rosmarinus officinalis, Jasminum sambac, Piper nigrum and so many other plants are reported for neuroprotective effects. This review article was aimed to summarize the current finding on EOs tested against neurodegenerative disorders like Alzheimer disease (AD) and dementia. The effects of EOs on pathological targets of AD and dementia including amyloid deposition (Aβ), neurofibrillary tangles (NFTs), cholinergic hypofunction, oxidative stress and glutamatergic abnormalities were focused. Furthermore, effects of EOs on other neurological disorders including anxiety, depression, cognitive hypofunction epilepsy and convulsions were also evaluated in detail. In conclusion, EOs were effective on several pathological targets and have improved cognitive performance in animal models and human subjects. Thus, EOs can be developed as multi-potent agents against neurological disorders with better efficacy, safety and cost effectiveness.

In silico and in vivo anti-malarial studies of 18β glycyrrhetinic acid from Glycyrrhiza glabra.

Komal Kalani

Full Text Available Malaria is one of the most prevailing fatal diseases causing between 1.2 and 2.7 million deaths all over the world each year. Further, development of resistance against the frontline anti-malarial drugs has created an alarming situation, which requires intensive drug discovery to develop new, more effective, affordable and accessible anti-malarial agents possessing novel modes of action. Over the past few years triterpenoids from higher plants have shown a wide range of anti-malarial activities. As a part of our drug discovery program for anti-malarial agents from Indian medicinal plants, roots of Glycyrrhizaglabra were chemically investigated, which resulted in the isolation and characterization of 18β-glycyrrhetinic acid (GA as a major constituent. The in vitro studies against P. falciparum showed significant (IC50 1.69 µg/ml anti-malarial potential for GA. Similarly, the molecular docking studies showed adequate docking (LibDock score of 71.18 for GA and 131.15 for standard anti-malarial drug chloroquine. Further, in silico pharmacokinetic and drug-likeness studies showed that GA possesses drug-like properties. Finally, in vivo evaluation showed a dose dependent anti-malarial activity ranging from 68-100% at doses of 62.5-250 mg/kg on day 8. To the best of our knowledge this is the first ever report on the anti-malarial potential of GA. Further work on optimization of the anti-malarial lead is under progress.

The purpose of this study was to evaluate the applicability of the National Institute for Health and Clinical Excellence (NICE) guidelines for imaging studies in children under the age of three with first urinary tract infection (UTI). In our cohort of 112 patients, we gathered data regarding the occurrence of indications for ultrasonography (US) and voiding cystourethrography (VCUG) according to the NICE guidelines, dimercaptosuccinic acid (DMSA) scintigraphy examinations, UTI recurrence, antimicrobial prophylaxis (AMP), anti-reflux procedures, and other urological procedures. If the NICE guidelines had been applied, 13 of the 25 patients (52 %) with vesicoureteral reflux (VUR), including 6 of the 12 patients (50 %) with dilating VUR and 3 of the 4 patients who underwent endoscopic anti-reflux treatment, would have been missed, and a negative VCUG would have been avoided in 25 of the 42 patients (60 %) with no VUR. None of the missed diagnoses occurred in the younger boys' group. Based on these preliminary analyses, we feel that the NICE guidelines for imaging studies in children under 3 years old with UTI may be applicable to clinical use only in boys under 6 months of age. For other patients the guidelines were unsuccessful.

Zinc is a potent mediator to body endurance against infection by affecting the function of the cellular immune system which act as the main response in tuberculosa infection. Low level of zinc in the blood, called hipozinsemia, is more often found in child tuberculosis (TB patients who have not taken anti tuberculoses drugs than those who have received drug therapy. Several previous studies show that there were no different levels of zinc between intensive phase and follow-up phase of therapies, however others indicated contrary results. Objective. The purpose of study is to determine whether there is any differences of serum zinc levels in the intensive phase and follow-up phase of anti-tuberculosis drug as well as to assess the relationship between treatment duration and serum zinc levels. Method. A cross-sectional study design was used with research subjects were children aged 6-59 months who were taken anti-tuberculosis drugs in Bogor District, in 2013. Data analysis used was independent t test and correlation test. Results. There was significant mean difference of serum zinc levels between subject who took anti-tuberculosis drugs in the intensive phase compare to those in the follow-up phase (p=0.015.There was a significant positive correlation between the duration of treatment and the serum zinc levels after controlling nutritional status (r=0.363 p=0.003. Conclusion. Serum zinc levels will increase linearly with tuberculosis drugs treatment duration. A further research is needed to determine whether there is any benefit of zinc supplementation in the intensive phase.

Globally, the aging population is growing rapidly, creating an urgent need to attenuate age-related health conditions, including metabolic disease and disability. A promising strategy for healthy aging based on consistently positive results from studies with a variety of species, including non-human primates (NHP), is calorie restriction (CR), or the restriction of energy intake while maintaining intake of essential nutrients. The burgeoning evidence for this approach in humans is reviewed and the major study to date to address this question, CALERIE (Comprehensive Assessment of the Long-term Effects of Reducing Intake of Energy), is described. CALERIE findings indicate the feasibility of CR in non-obese humans, confirm observations in NHP, and are consistent with improvements in disease risk reduction and potential anti-aging effects. Finally, the mechanisms of CR in humans are reviewed which sums up the fact that evolutionarily conserved mechanisms mediate the anti-aging effects of CR. Overall, the prospect for further research in both NHP and humans is highly encouraging. Copyright © 2017 Elsevier B.V. All rights reserved.

Apple Can Act as Anti-Aging on Yeast Cells

Directory of Open Access Journals (Sweden)

Vanessa Palermo

2012-01-01

Full Text Available In recent years, epidemiological and biochemical studies have shown that eating apples is associated with reduction of occurrence of cancer, degenerative, and cardiovascular diseases. This association is often attributed to the presence of antioxidants such as ascorbic acid (vitamin C and polyphenols. The substances that hinder the presence of free radicals are also able to protect cells from aging. In our laboratory we used yeast, a unicellular eukaryotic organism, to determine in vivo efficacy of entire apples and their components, such as flesh, skin and polyphenolic fraction, to influence aging and oxidative stress. Our results indicate that all the apple components increase lifespan, with the best result given by the whole fruit, indicating a cooperative role of all apple components.

Anti-tumor necrosis factor-α (TNFα) therapy has improved the prognosis of many chronic inflammatory diseases. It appears to be well-tolerated by liver-transplant patients. However, their use and their safety in kidney-transplant patients have yet to be determined.In this retrospective study, we identified 16 adult kidney-transplant patients aged 46.5 years (34-51.8) who received anti-TNFα therapy from 7 kidney transplantation centers. The indications for this treatment included: chronic inflammatory bowel disease (n = 8), inflammatory arthritis (n = 5), AA amyloidosis (n = 1), psoriasis (n = 1), and microscopic polyangiitis (n = 1).Anti-TNFα therapies resulted in a clinical response in 13/16 patients (81%). Estimated glomerular filtration rates (MDRD-4) were similar on day 0 and at 24 months (M24) after anti-TNFα treatment had been initiated (41 [12-55] and 40 [21-53] mL/min/1.73 m, respectively). Two allograft losses were observed. The 1st case was due to antibody-mediated rejection (M18), while the 2nd was the result of AA amyloidosis recurrence (M20). There were several complications: 8 patients (50%) developed 23 serious infections (18 bacterial, 4 viral, and 1 fungal) and 4 developed cancer. Five patients died (infection n = 2, cardiac AA amyloidosis n = 1, intraalveolar hemorrhage following microscopic polyangiitis n = 1, and acute respiratory distress syndrome n = 1). On univariate analysis, recipient age associated with death (P = 0.009) and infection development (P = 0.06).Using anti-TNFα therapies, remission can be achieved in chronic inflammatory diseases in kidney-transplant patients. However, concommitant anti-TNFα and immunosuppresive therapies must be used with caution due to the high risk of infection, particularly after the age of 50.

Primary vaccination with combined vaccine against viral hepatitis A (VHA) and viral hepatitis B (VHB) induces higher anti-hepatitis B surface (anti-HBs) antibody responses and similar anti-hepatitis A virus (anti-HAV) antibody responses in adults aged over 40 years in comparison with concomitant monovalent vaccines against VHA and VHB. Th e objectives were to assess, in a clinical study, persistence of anti-HAV and anti-HBs antibodies in adults aged over 40 years four years after primary VHA/VHB vaccination and antibody response following a booster dose of the vaccine. Five hundred and ninety-six subjects aged > 40 years were vaccinated with three doses of the combined VHA/VHB vaccine at Months 0, 1, 6 (HAB group) or with concomitant VHA and VHB vaccines at Months 0, 6 and 0, 1, 6 (ENG+HAV and HBVX+VAQ, respectively). Blood samples were collected one month following primary vaccination (Month 7) and then at one-year intervals for four years after the booster dose with the same vaccine as used for the primary vaccination. The anti-HBs and anti-HAV antibody levels were determined prior to the booster dose and at days 14 and 30 after the booster dose. At Month 7, > 97% of study subjects were seropositive for anti-HAV antibodies in all groups analyzed. Four years after primary vaccination, anti-HAV antibody seropositivity persisted in > 93% of study subjects, increasing to > 99% after the booster dose. At Month 7, the highest proportion of study subjects with anti-HBs antibody levels > or = 10 mIU/ml was found in the HAB group (91.7% versus 79.7% in the ENG+HAV group versus 71.0% in the HBVX+VAQ group). Four years after vaccination, anti-HBs antibody levels of 10 mIU/ml persisted in 57.1% of the HAB study subjects in comparison with 40.1% and 26.6% of the study subjects in the ENG+HAV and HBVX+VAQ groups, respectively. One month after the booster dose, anti-HBs antibody levels increased and antibody levels > or = 10 mIU/ml was achived in 95.2% of study subjects in the

Full Text Available Background The prevalence of hepatitis B viral (HBV infection in Indonesia is high. The most effective way to control HBV infection is by hepatitis B (HB immunization. Many studies reported that hepatitis B surface antibody (anti-HBs seroprotection declines in children > 10 years of age. In addition many factors can influence anti-HBs titer. Objective To measure anti-HBs titer and evaluate possible factors associated with anti-HBs titer. Methods This cross sectional  study was conducted in children 10-15 years of age from ten schools at Tuminting District, Manado, North Sulawesi, from October to November 2014. All subjects had completed the hepatitis B immunization scheme. By stratified random sampling, 105 children were selected as subjects. Data was analyzed with SPSS version 22. Results. From 48 schools, we selected 10 schools from which to draw a total of 105 children, but only 23 (21.9% children had detectable anti-HBs . Of all subjects, 76 (72.4%  were female, 78 (74.3%  had good nutritional status, and 98 (93.3%  had birth weight ≥2,500 grams. Data from immunization record books showed that 26 (24.8% subjects received the HB-1 vaccination at ≤7 days of age and 45 (42.9% subjects had a ≥2 month interval between the HB-2 and HB-3 vaccinations. Multivariate analysis showed that administration of HB-1 at ≤7 days of age  and a ≥2 month interval between HB-2 and HB-3  had significant associations with anti-HB seroprotection in children. Conclusion A low proportion of subjects who had completed the hepatitis B immunization scheme had detectable anti-HBs titer (21.9%. Administration of HB-1 at ≤7 days of age and a ≥2-month interval between HB-2 and HB-3 vaccinations are important factors in anti-HB seroprotection in children aged 10-15 years.

Parylene C is used in a device because of its conformable deposition and other advantages. Techniques to study Parylene C aging were developed, and "lessons learned" that could be utilized for future studies are the result of this initial study. Differential Scanning Calorimetry yielded temperature ranges for Parylene C aging as well as post-deposition treatment. Post-deposition techniques are suggested to improve Parylene C performance. Sample preparation was critical to aging regimen. Short-term (%7E40 days) aging experiments with free standing and ceramic-supported Parylene C films highlighted "lessons learned" which stressed further investigations in order to refine sample preparation (film thickness, single sided uniform coating, machine versus laser cutting, annealing time, temperature) and testing issues ("necking") for robust accelerated aging of Parylene C.

has been an epidemiological transition. While the prevalence of infectious diseases such as malaria, tuberculosis and dengue fever is still high, the incidence of non-communicable diseases is increasing. High rates of morbidity becomes good opportunity to develop medicine for infectious diseases as well as non-communicable diseases to get patent because of a very large market share. Unfortunately, the vast market potential is only captured by foreign countries. Data from the Directorate General of Intellectual Property Rights (IPR DG in 2010 showed that domestic patent applicants who get approval (granted were only 4.6% while overseas were 92.03%. This situation is very ironic, since Indonesia is a country with potential basic ingredient of natural medicines and the third highest biodiversity after Brazil and China. The aim of this study was to evaluate patent situation of medicine registered in IPR DG, Law & Human Rights Ministry in the last 7 years (2005 to 2011 for infectious diseases (malaria and tuberculosis and non communicable (hypertension and diabetes. This study used observational method by tracing patent documents from web addresses of the relevant agencies. It showed that Indonesia only registered 4.9% patent from all patents registered in IPR DG from 2005 to 2011. Indonesia only registered 3.4% from 89 patents for anti-hypertension, 4.8% from 250patents for anti-diabetic, and 21.1% from 18 patents for anti-malaria, and 7.1% from 14 patents for antituberculosis. Most of the patents filled or registered by Indonesian registrant is a patent medicine of herbs’ extract or its composition, it was concluded that medicine patents for non-communicable diseases and infectious diseases in Indonesia are dominated by foreign country.Keywords : Patent situation, medicine, IPR-DG, Indonesia

The aim was to assess work-loss days before and after commencement of anti-TNF treatment in patients with non-radiographic axial spondylarthritis (nr-axSpA). Bionaïve nr-axSpA patients (n = 75), aged 17-62 years, fulfilling the Assessment of SpondyloArthritis international Society criteria for axial spondyloarthritis and starting anti-TNF treatment during 2004-11, were retrieved from the observational South Swedish Arthritis Treatment Group study. Patient information was linked to Swedish Social Insurance Agency data on sick leave and disability pension from 1 year before to 2 years after anti-TNF initiation. Matched population references were included for comparison and to adjust for secular trends. The nr-axSpA patients had a median age of 35 years and disease duration of 6 years at the start of treatment. During the 2 years after anti-TNF initiation, mean work-loss days (including both sick leave and disability pension) in the nr-axSpA group decreased significantly from 3.4 to 1.9 times more than among the population references. The effect was seen on sick leave, whereas disability pension levels remained similar in both groups throughout. Anti-TNF therapy in nr-axSpA was associated with a significant and sustained improvement of work disability over 2 years. However, the proportion of work-loss days remained almost twice as high as in the general population at the end of follow-up. © The Author 2017.

In order to increase the validity of age estimation in adolescents and young adults when there is no legitimation for X-ray examinations, it seems desirable to be able to assess the mineralization of third molars using X-ray-free imaging procedures. In the present study, the mineralization stages of lower third molars were determined prospectively in 269 male and 248 female individuals aged 12 to 24 years using 3.0 T MRI. The classification system of Demirjian et al. was used to determine the stages. This study presents the minima and maxima, means and standard deviations, median values, and lower and upper quartiles separately for both sexes, for the mineralization stages B-H. Statistically significant sex differences were observed for the mineralization stages C, E, F, and G, and a faster developmental rate was observed for males. It was concluded that magnetic resonance imaging is an X-ray-free alternative to orthopantomography when assessing mineralization of third molars.

Full Text Available Althoughmicrobial fertilizer is multi-effect,environmental friendly and long-term efficient,its practical application effect is but decreased for being prey by the other creators living in soil frequently.Many bacterium have developed their mechanisms that expel or kill worms to defend themselves from predators.Screening of anti-predator rhizosphere bacterium helps us to find out competitive plant growth promoting rhizobacteria(PGPR.Using Caenorhabditis elegans as sample,this study roughly observed two strains of biocontrol:Pseudomonas aurantiaca JD37 and Pseudomonas fluorescens P13.Using Escherichia coli OP50 as control group,we find the preference order of worms,from highest to lowest,is P13,OP50 and JD37.In slow killing assay,the death rate of worms for JD37 and P13 are 26.12% and 18.66% respectively.The activity and reproduction rate of C.elegans decrease when it is fed on JD37.The results of chemical and micro-biological study show that JD37 cannot produce any currently studied second metabolites which kill worms,while P13 can produce Hydrogen cyanide (HCN.All these results show that JD37 has the ability of anti-predator,and is more competitive under predation pressure,which suggests its broad application prospect as microbial fertilizer.

Recent studies have suggested that the birth order effect in allergy may be established during the prenatal period and that the protective effect may originate in the mother. HLA class II disparity between mother and foetus has been associated with significantly increased Th1 production. In this study, we investigated whether production of HLA antibodies 4 years after pregnancy with index child is associated with allergic outcomes in offspring at 8 years. Anti-HLA class I and II antibodies were measured in maternal serum (n = 284) and levels correlated to numbers of pregnancies and birth order, and allergic outcomes in offspring at 8 years of age. Maternal anti-HLA class I and II antibodies were significantly higher when birth order, and the number of pregnancies were larger. Anti-HLA class II, but not class I antibodies were associated with significantly less atopy and seasonal rhinitis in the offspring at age 8 years. Mothers with nonatopic (but not atopic) offspring had a significant increase in anti-HLA class I and II antibodies with birth order. This study suggests that the 'birth order' effect in children may be due to parity-related changes in the maternal immune response to foetal antigens. We have observed for the first time an association between maternal anti-HLA class II antibodies and protection from allergy in the offspring. Further work is required to determine immunologically how HLA disparity between mother and father can protect against allergy. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Use of potentially inappropriate medications may result in increased morbidity, mortality and resource utilisation. Due to polypharmacy and age-related decline in renal function the elderly population is at particular risk. Therefore, the Beers Criteria include use of nonsteroidal anti-inflammatory drugs in chronic renal failure stage 4 and 5 as these drugs may worsen renal function. According to the summary of product characteristics, the nonsteroidal anti-inflammatory drugs ibuprofen and diclofenac are contraindicated in these patients. Objective was to assess the extent of nonsteroidal anti-inflammatory drug use in nursing homes with a focus on residents with severe renal failure. Multi-centre cross-sectional study in 21 German nursing homes. The study population comprised residents for whom at least one serum creatinine value and information about sex were available, so that creatinine clearance rate could be estimated. In all, 685 of 852 residents were included as they fulfilled the abovementioned criteria. Renal failure was severe (estimated creatinine clearance rate renal failure (20.8 %). With one exception, all residents prescribed nonsteroidal anti-inflammatory drugs with severe renal failure were treated with at least one nonsteroidal anti-inflammatory drug that was contraindicated due to the underlying renal function. Notwithstanding their classification as potentially inappropriate medications and underlying contraindications, use of nonsteroidal anti-inflammatory drugs is common among nursing home residents with severe renal failure.

Do the disadvantaged legitimize the social system? A large-scale test of the status-legitimacy hypothesis.

Science.gov (United States)

Brandt, Mark J

2013-05-01

System justification theory (SJT) posits that members of low-status groups are more likely to see their social systems as legitimate than members of high-status groups because members of low-status groups experience a sense of dissonance between system motivations and self/group motivations (Jost, Pelham, Sheldon, & Sullivan, 2003). The author examined the status-legitimacy hypothesis using data from 3 representative sets of data from the United States (American National Election Studies and General Social Surveys) and throughout the world (World Values Survey; total N across studies = 151,794). Multilevel models revealed that the average effect across years in the United States and countries throughout the world was most often directly contrary to the status-legitimacy hypothesis or was practically zero. In short, the status-legitimacy effect is not a robust phenomenon. Two theoretically relevant moderator variables (inequality and civil liberties) were also tested, revealing weak evidence, null evidence, or contrary evidence to the dissonance-inspired status-legitimacy hypothesis. In sum, the status-legitimacy effect is not robust and is unlikely to be the result of dissonance. These results are used to discuss future directions for research, the current state of SJT, and the interpretation of theoretically relevant but contrary and null results.

Background and purpose: We previously showed that irradiating the carotid arteries of ApoE{sup -/-} mice accelerated the development of macrophage-rich, inflammatory and thrombotic atherosclerotic lesions. In this study we investigated the potential of anti-inflammatory (atorvastatin, CD40L knockout) and anti-thrombotic (clopidogrel) intervention strategies to inhibit radiation-induced atherosclerosis. Material and methods: ApoE{sup -/-} mice were given 0 or 14 Gy to the neck and the carotid arteries were harvested at 4 or 28 weeks after irradiation. Atorvastatin (15 mg/kg/day) or clopidogrel (20 mg/kg/day) was given in the chow; control groups received regular chow. Clopidogrel inhibited platelet aggregation by 50%. CD40L{sup -/-}/ApoE{sup -/-} and ApoE{sup -/-} littermates were also given 0 or 14 Gy to the neck and the carotid arteries were harvested after 30 weeks. Results: Clopidogrel decreased MCP-1 expression in the carotid artery at 4 weeks after irradiation. Expression of VCAM-1, ICAM-1, thrombomodulin, tissue factor and eNOS was unchanged in atorvastatin and clopidogrel-treated mice. Neither drug inhibited either age-related or radiation-induced atherosclerosis. Furthermore, loss of the inflammatory mediator CD40L did not influence the development of age-related and radiation-induced atherosclerosis. Conclusions: The effects of radiation-induced atherosclerosis could not be circumvented by these specific anti-inflammatory and anti-coagulant therapies. This suggests that more effective drug combinations may be required to overcome the radiation stimulus, or that other underlying mechanistic pathways are involved compared to age-related atherosclerosis.

Background and purpose: We previously showed that irradiating the carotid arteries of ApoE −/− mice accelerated the development of macrophage-rich, inflammatory and thrombotic atherosclerotic lesions. In this study we investigated the potential of anti-inflammatory (atorvastatin, CD40L knockout) and anti-thrombotic (clopidogrel) intervention strategies to inhibit radiation-induced atherosclerosis.

Atorvastatin (15 mg/kg/day) or clopidogrel (20 mg/kg/day) was given in the chow; control groups received regular chow. Clopidogrel inhibited platelet aggregation by 50%. CD40L −/− /ApoE −/− and ApoE −/− littermates were also given 0 or 14 Gy to the neck and the carotid arteries were harvested after 30 weeks.

The antigen specificity of anti-phospholipid antibodies in infectious mononucleosis (IM) was studied using ELISA for the detection of anti-β2-glycoprotein I (β2-GPI), anti-annexin V, anti-protein S and anti-prothrombin antibodies and TLC immunostaining for the detection of anti-phospholipid antibodies. This technique enabled us to look at antibodies reacting to ‘pure’ phospholipid antigens in the absence of protein contamination. Sera from 46 patients with IM, 18 with systemic lupus erythematosus (SLE), 21 with primary anti-phospholipid antibody syndrome (PAPS), 50 with Helicobacter pylori infection and 30 healthy blood donors were tested. This study highlights anti-phospholipid antibodies in patients with IM as specific ‘pure’ anti-cardiolipin antibodies, while in PAPS and SLE patients anti-phosphatidylserine and anti-phosphatidylethanolamine antibodies were also found. This investigation also shows that the anti-cardiolipin antibodies found in IM can be present with anti-cofactor protein antibodies. The higher prevalence of anti-cofactor antibodies found in IM sera than in Helicobacter pylori sera may be due to the immunostimulatory effect and/or the polyclonal activation often observed in course of Epstein–Barr virus infection. However, anti-β2-GPI and, to a lesser extent, anti-prothrombin antibodies occur with a significantly lower prevalence in IM than in PAPS patients. This finding suggests that these antibodies should be regarded as the expression of the broad autoimmune syndrome involving the phospholipid-binding plasma proteins. PMID:10792380

2015-05-01

Chronic inflammation has been proposed as one of the main molecular mechanisms of aging and age-related diseases. Although evidence in humans is limited, short-term calorie restriction (CR) has been shown to have anti-inflammatory effects in aged experimental animals. We reported on the long-term treatment of daumone, a synthetic pheromone secreted by Caenorhabditis elegans in an energy deficient environment, extends the life-span and attenuates liver injury in aged mice. The present study examined whether late onset short-term treatment of daumone exerts anti-inflammatory effects in the livers of aged mice. Daumone was administered orally at doses of 2 or 20 mg/kg/day for 5 weeks to 24-month-old male C57BL/6J mice. Increased liver macrophage infiltration and gene expression of proinflammatory cytokines in aged mice were significantly attenuated by daumone treatment, suggesting that short-term oral administration of daumone may have hepatoprotective effects. Daumone also dose-dependently suppressed tumor necrosis factor-α (TNF-α)-induced nuclear factor-κB (NF-κB) phosphorylation in HepG2 cells. The present data demonstrated that short-term treatment of daumone has anti-inflammatory effects in aged mouse livers possibly through suppression of NF-κB signaling and suggest that daumone may become a lead compound targeting aging and age-associated diseases.
