    Full Text Available The first Jewish medical graduates at the University of Padua qualified in the fifteenth century. Indeed, Padua was the only medical school in Europe for most of the medieval period where Jewish students could study freely. Though Jewish students came to Padua from many parts of Europe the main geographical sources of its Jewish students were the Venetian lands. However, the virtual Padua monopoly on Jewish medical education came to an end during the seventeenth century as the reputation of the Dutch medical school in Leiden grew. For aspiring medieval Jewish physicians Padua was, for around three hundred years, the first, simplest, and usually the only choice.

    Human life is a staggeringly strange thing. On the surface of a ball of rock falling around a nuclear fireball in the blackness of a vacuum the laws of nature conspired to create a naked ape that can look up at the stars and wonder where it came from. What is a human being? Objectively, nothing of consequence. Particles of dust in an infinite arena, present for an instant in eternity. Clumps of atoms in a universe with more galaxies than people. And yet a human being is necessary for the question itself to exist, and the presence of a question in the universe - any question - is the most wonderful thing. Questions require minds, and minds bring meaning. What is meaning? I don't know, except that the universe and every pointless speck inside it means something to me. I am astonished by the existence of a single atom, and find my civilisation to be an outrageous imprint on reality. I don't understand it. Nobody does, but it makes me smile. This book asks questions about our origins, our destiny, and our place i...

    Full Text Available This article contains a report on the international conference organized by the University of Leiden in May 2015. According to its organizers, this conference has become the first Western European symposium dedicated to the study of the long history of the Golden Horde. The conference became a fruitful meeting place of the leading Russian and Tatar historians and archaeologists with their Western colleagues from the Netherlands, United Kingdom, United States of America, Hungary, Poland, and Finland. International participants of the Leiden conference discussed the most topical issues of historiography associated with eventful history of the Golden Horde. In particular, the conference participants paid special attention to the study of the administration of the ulus of Jochi that naturally combined governmental models of the Mongol Empire of the Chingizids with local administrative elements. A separate section of the conference was devoted to the analysis of the religious policy of the Golden Horde khans, where special attention was paid to the historiographical debate on the Islamization of the ulus of Jochi. The conference participants also paid considerable attention to the consideration of the material culture of the Golden Horde known both from written sources and, above all, from the materials of archaeological findings. Also, a number of reports of the confe­rence was devoted to foreign and domestic policies of the Golden Horde rulers, at the same time reflecting the central geopolitical role of the ulus of Jochi on the Eurasian continent and the high level of civilization of the Golden Horde. The main achievement of the Leiden conference was a statement on the need of deeper study of the Golden Horde history in order to overcome a number of stereotypes regarding misconceptions of the ulus of Jochi represented as backward and parasitic State formation. The conference participants agreed in general opinion about the necessity of similar

    Directory of Open Access Journals (Sweden)

    Wendy Hamblet

    2012-03-01

    Full Text Available As many violence scholars, I have not found myself to be greatly interested in cruelty, for the simple reason that instances of cruelty are relatively rare, if we accept its usual definition as “willful indifference to suffering, or taking pleasure in inflicting such suffering upon sentient beings.” Most people do not actively wish harm to others, and for this reason, the harms that keep our societies running smoothly and in ordered fashion must be kept in concealment, far from our direct vision, if we are to be asked to tolerate them—cruel punishments, executions, exclusions of minorities from the full benefits of the society, etc. However, Michael Trice’s new book, Encountering Cruelty, renews a fresh interest in this dark topic by redefining cruelty as an ordinary, common occurrence, infecting the everyday in ever more subtle forms. Trice reveals how a too narrow definition of cruelty may grant us the comfort of believing its occurrence to be minimal, but it robs us of the opportunity to track its traces writ large across the landscape of the human world. We cannot hope to understand, and ultimately heal, the rebounding effects of suffering across the broader social terrain, unless we are willing to admit the cruelty that underlies modern institutional life.

  9. Factor V Leiden thrombophilia.

    Science.gov (United States)

    Kujovich, Jody Lynn

    2011-01-01

    Factor V Leiden is a genetic disorder characterized by a poor anticoagulant response to activated Protein C and an increased risk for venous thromboembolism. Deep venous thrombosis and pulmonary embolism are the most common manifestations, but thrombosis in unusual locations also occurs. The current evidence suggests that the mutation has at most a modest effect on recurrence risk after initial treatment of a first venous thromboembolism. Factor V Leiden is also associated with a 2- to 3-fold increased relative risk for pregnancy loss and possibly other obstetric complications, although the probability of a successful pregnancy outcome is high. The clinical expression of Factor V Leiden is influenced by the number of Factor V Leiden alleles, coexisting genetic and acquired thrombophilic disorders, and circumstantial risk factors. Diagnosis requires the activated Protein C resistance assay (a coagulation screening test) or DNA analysis of the F5 gene, which encodes the Factor V protein. The first acute thrombosis is treated according to standard guidelines. Decisions regarding the optimal duration of anticoagulation are based on an individualized assessment of the risks for venous thromboembolism recurrence and anticoagulant-related bleeding. In the absence of a history of thrombosis, long-term anticoagulation is not routinely recommended for asymptomatic Factor V Leiden heterozygotes, although prophylactic anticoagulation may be considered in high-risk clinical settings. In the absence of evidence that early diagnosis reduces morbidity or mortality, decisions regarding testing at-risk family members should be made on an individual basis.

  10. Factor V Leiden and Inflammation

    2012-01-01

    Full Text Available Factor V Leiden, is a variant of human factor V (FV, also known as proaccelerin, which leads to a hypercoagulable state. Along these years, factor V Leiden (FVL has been studied from the pathophysiologic point of view, and research has been focused on finding clinical approaches for the management of the FVL associated to a trombophilic state. Less attention has been paid about the possible role of FVL in inflammatory conditions known to be present in different disorders such as uremia, cirrhosis, liver transplantation, depression as well as sepsis, infection or, inflammatory bowel disease (IBD. Whether platelet FVL will increase the activation of coagulation and/or in which proportion is able to determine the final outcome in the previously mentioned inflammatory conditions is a subject that remains uncertain. This paper will review the association of FVL with inflammation. Specifically, it will analyze the important role of the endothelium and the contribution of other inflammatory components involved at both the immune and vascular levels. This paper will also try to emphasize the importance of being a FVL carrier in associations to diseases where a chronic inflammation occurs, and how this condition may be determinant in the progression and outcome of a specific clinic situation.

  12. Leiden reconstructed human epidermal model as a tool for the evaluation of the skin corrosion and irritation potential according to the ECVAM guidelines.

    2008-08-01

    In the ECVAM validation studies two common skin protocols have been developed, the skin corrosion and skin irritation protocol. Both protocols include next to general and functional conditions that the skin model must meet, also the correct prediction of the activity of certain reference chemicals. For the skin corrosion protocol, the OECD TG 431 defined 12 reference chemicals that should be correctly predicted by the epidermal skin model. For skin irritation 20 test substances should meet the defined criteria. In this study we aimed to subject our Leiden human epidermal (LHE) model to both common protocols according to the ECVAM guidelines. The LHE model generated in this study has been fully characterized and shows very high similarities with the native skin. After minor technical changes in both protocols, corrosion classifications were obtained in concordance with those reported for the validated human skin models EpiSkin and EpiDerm. The results obtained with the common skin irritation protocol were very similar to that of earlier studies with the SkinEthic, EpiSkin and EpiDerm models. This means that the protocols and prediction models developed during the validation studies with a specific skin model can be used with other similar skin models. This study demonstrates that reconstructed human skin equivalents have been proven to be efficient and reliable alternatives to animal testing.

    2015-01-01

    Summary Background The high allelic frequency of the prothrombotic Leiden polymorphism in human blood coagulation factor V (fV) has been speculated to reflect positive selection during evolution. Heterozygous Leiden carriers enrolled in the placebo arm of the PROWESS sepsis trial, and heterozygous Leiden mice challenged with endotoxin both showed reduced mortality, whereas homozygous Leiden mice were not protected from lethal endotoxemia. Follow-up analyses of clinical outcomes, and of mouse models of infection with various pathogens remained inconclusive. Objective To establish whether aPC-resistance of fV Leiden modifies the outcome of bacterial infection in murine sepsis models. Methods Homozygous and heterozygous fV Leiden mice were subjected to gram-positive (S.aureus) or gram-negative (Y.pestis; E.coli) septic peritonitis, or polymicrobial, focal septic peritonitis induced by cecal ligation and puncture (CLP); and the effect of fV Leiden on 7-day survival and bacterial dissemination was assessed. Outcomes were compared to the sepsis survival of mice with genetically impaired hemostasis (hemophilia A, thrombocytopenia, thrombin receptor PAR4 deficiency, protein C receptor ProcR/EPCR-deficiency). Results Heterozygous, but not homozygous Leiden mice were protected from lethal infection with highly virulent S.aureus and Y.pestis strains. FV Leiden did not affect the outcome of sepsis induced by CLP, staphylokinase-deficient S.aureus, Pla-deficient Y.pestis, or E.coli. Thrombocytopenia, deficiency of PAR1 or PAR4 did not affect S.aureus sepsis survival, whereas hemophilia A increased mortality. ProcR-deficiency selectively abolished the survival advantage of heterozygous Leiden mice. Conclusions In mice, heterozygous fV Leiden carriers are protected from sepsis mortality after infection with clinically relevant human bacterial pathogens. PMID:25690763

    The objectives of this study were to investigate the prevalence of factor V Leiden mutation in Malay women with recurrent spontaneous abortion and to clarify the contribution of the factor V Leiden mutation to recurrent miscarriages in these women. A prospective case control study between June 1999 and April 2000. Hospital University Science of Malaysia, Kubang Kerian, Kelantan, and Maternal and Child Health Clinic, Pasir Mas, Kelantan, Malaysia. A total of 46 Malay women with a history of three or more first or second trimester miscarriages were studied. The control group consisted of 46 parous women without obstetric complications. Diagnosis of factor V Leiden mutation was made by examination of factor V Leiden allele product following Mnl I digestion of factor V Leiden alleles amplified by polymerase chain reaction. None of the 46 women with recurrent spontaneous abortion carried the mutation. Also, we found no subject carrying the factor V Leiden alleles in the control group. These results suggest that that there is no association between the factor V Leiden mutation and recurrent spontaneous abortion in the Malay population.

    Human-associated microbial communities have a crucial role in determining our health and well-being, and this has led to the continuing development of microbiome-based therapies such as faecal microbiota transplantation. These microbial communities are very complex, dynamic and highly personalized ecosystems, exhibiting a high degree of inter-individual variability in both species assemblages and abundance profiles. It is not known whether the underlying ecological dynamics of these communities, which can be parameterized by growth rates, and intra- and inter-species interactions in population dynamics models, are largely host-independent (that is, universal) or host-specific. If the inter-individual variability reflects host-specific dynamics due to differences in host lifestyle, physiology or genetics, then generic microbiome manipulations may have unintended consequences, rendering them ineffective or even detrimental. Alternatively, microbial ecosystems of different subjects may exhibit universal dynamics, with the inter-individual variability mainly originating from differences in the sets of colonizing species. Here we develop a new computational method to characterize human microbial dynamics. By applying this method to cross-sectional data from two large-scale metagenomic studies—the Human Microbiome Project and the Student Microbiome Project—we show that gut and mouth microbiomes display pronounced universal dynamics, whereas communities associated with certain skin sites are probably shaped by differences in the host environment. Notably, the universality of gut microbial dynamics is not observed in subjects with recurrent Clostridium difficile infection but is observed in the same set of subjects after faecal microbiota transplantation. These results fundamentally improve our understanding of the processes that shape human microbial ecosystems, and pave the way to designing general microbiome-based therapies.

    Recent studies proved that inflammatory bowel disease (IBD) patients had a higher risk of thromboembolism and a Factor V Leiden mutation that prevents the efficient inactivation of factor V, which leads to thromboembolism and thus contributes to a high potential risk of IBD. However, the relationship between Factor V Leiden mutation and IBD remains controversial. We conducted a systematic review with meta-analysis of studies assessing the association of Factor V Leiden mutation with the risk of IBD in humans. We extracted the number of IBD and control subjects with or without Factor V Leiden mutation from each study and conducted this analysis using a fixed-effects model. Nineteen studies met the inclusion criteria and were included in the meta-analysis. No significant heterogeneity was found in results across the 19 studies (I (2) = 18.8%, P = 0.23), which showed a slight but not significant increase in the risk of IBD with Factor V Leiden mutation in the general population (summary odds ratio [OR] 1.13, 95% confidence interval [CI] 0.87-1.46). Taking into account ethnic differences, further study exhibited a slight but not significant increase in risk of IBD with Factor V Leiden mutation in Europeans (summary OR 1.20, 95% CI 0.88-1.64). However, Factor V Leiden mutation was significantly associated with a higher risk of thromboembolism in IBD patients (summary OR 5.30, 95% CI 2.25-12.48). No publication bias was found in this study. This meta-analysis indicated that although Factor V Leiden mutation was not significantly associated with the risk of IBD, it was significantly associated with a higher risk of thromboembolism in IBD patients.

    Albert Einstein accepted a "special" visiting professorship at the University of Leiden in the Netherlands in February 1920. Although his appointment should have been a mere formality, it took until October of that year before Einstein could occupy his special chair. Why the delay? The explanation involves a case of mistaken identity with Carl Einstein, Dadaist art, and a particular Dutch fear of revolutions. But what revolutions was one afraid of? The story of Einstein's Leiden chair throws new light on the reception of relativity and its creator in the Netherlands and in Germany.

    Full Text Available This paper aims to contribute to a constructive debate on human rights. The two World Wars of the last century brought about the creation of the United Nations aimed “to reaffirm faith in fundamental human rights, in the dignity and worth of the human person, in the equal rights of men and women and of nations large and small”. Only three years later the Universal Declaration of the Human Rights was elaborated and promoted by the UN, considered to be the foundation of international human rights law. Today, as globalization brings all closer together in a “global village”, one can see that there are many ways to perceive and guarantee human rights, in different states, but also within different states. Poverty, illiteracy, censorship, cruel treatment and even the lack of guarantee for the right to life are, unfortunately, the norm for many people of the world. Such observations bring up questions regarding the legitimacy, universality and coherence of human rights.

  15. Factor V Leiden: a case study and review.

    2010-01-01

    Venous thromboembolism accounts for approximately 600,000 hospitalizations and 50,000 deaths per year in the United States. Many inherited blood disorders predispose patients to this disorder. The most common of these disorders is factor V Leiden. Factor V Leiden thrombophilia is an inherited disorder, mutation, of the mechanisms of blood clotting. The mutation causes resistance to activated protein C and thus causes a defect in the natural anticoagulation system. This predisposes patients to recurrent deep vein thrombosis and in combination with other risk factors can cause significant morbidity. This article discusses the pathophysiology, disease characteristics, risk factors for venous thromboembolism, diagnosis and testing, management of factor V Leiden, and implications for nursing in regard to factor V Leiden. The frequency of factor V Leiden and its prevalence in thromboembolic disease emphasize the need for nursing professionals from many diverse backgrounds to better understand the consequences of the factor V Leiden mutation.

    We present a case of a patient with factor V Leiden with an antithrombin III activity of 67% who received a successful aortic valve replacement supported by cardiopulmonary bypass (CPB). A safe level of anticoagulation was achieved by monitoring activated clotting time (ACT) and heparin concentration ensuring adequate anticoagulation throughout the procedure. Results from ACT, heparin dose response, heparin protamine titration, and thrombelastography are given. Factor V Leiden patients can be safely anti-coagulated using heparin for CPB procedures when monitored with ACT, heparin protamine titration, and thrombelastography. Postoperative chest tube losses were 360 mL, less than half our institutional average. Anticoagulation for the pre-and post-operative phase is also discussed.

    It has been shown that thrombomodulin (TM) considerably delays factor XIII (FXIII) activation and this effect is abrogated by Factor V Leiden (FV(Leiden)) mutation. The aim of the study was to explore the effect of TM on the cross-linking of α(2)-plasmin inhibitor (α(2)-PI) to fibrin in plasma samples of different FV genotypes and how this effect is related to the impaired fibrinolysis of FV(Leiden) carriers. In the plasma samples of fifteen individuals with different FV genotypes and in FV deficient plasma supplemented with wild type FV or FV(Leiden) coagulation was initiated by recombinant human tissue factor and phospholipids with or without recombinant human TM (rhTM). In the recovered clots the extent of α(2)-PI-fibrin cross-linking was evaluated by Western blotting and quantitative densitometry. The effect of rhTM on tissue plasminogen activator (tPA) induced clot lysis was measured by turbidimetric method. rhTM significantly delayed the formation of α(2)-PI-fibrin α-chain heterodimers/oligomers in plasma samples containing wild type FV. This effect of rhTM was impaired in the presence of FV(Leiden). rhTM delayed tPA-induced clot lysis and this effect of rhTM was more pronounced in plasma containing FV(Leiden). When TAFIa was inhibited by potato carboxypeptidase inhibitor, rhTM accelerated clot lysis in the presence of wild type FV, which is explained by the delayed α(2)-PI-fibrin cross-linking. This effect of rhTM did not prevail in the presence of FV(Leiden). FV(Leiden) abrogates the delaying effect of rhTM on α(2)-PI-fibrin cross-linking, which contributes to the impaired fibrinolysis observed in FV(Leiden) carriers. Copyright © 2012 Elsevier Ltd.

  19. A universal law in human mobility

    The intrinsic factor that drives the human movement remains unclear for decades. While our observations from intra-urban and inter-urban trips both demonstrate a universal law in human mobility. Be specific, the probability from one location to another is inversely proportional to the number of population living in locations which are closer than the destination. A simple rank-based model is then presented, which is parameterless but predicts human flows with a convincing fidelity. Besides, comparison with other models shows that our model is more stable and fundamental at different spatial scales by implying the strong correlation between human mobility and social relationship.

  20. Human research ethics committees in technical universities.

    Human research ethics has developed in both theory and practice mostly from experiences in medical research. Human participants, however, are used in a much broader range of research than ethics committees oversee, including both basic and applied research at technical universities. Although mandated in the United States, the United Kingdom, Canada, and Australia, non-medical research involving humans need not receive ethics review in much of Europe, Asia, Latin America, and Africa. Our survey of the top 50 technical universities in the world shows that, where not specifically mandated by law, most technical universities do not employ ethics committees to review human studies. As the domains of basic and applied sciences expand, ethics committees are increasingly needed to guide and oversee all such research regardless of legal requirements. We offer as examples, from our experience as an ethics committee in a major European technical university, ways in which such a committee provides needed services and can help ensure more ethical studies involving humans outside the standard medical context. We provide some arguments for creating such committees, and in our supplemental article, we provide specific examples of cases and concerns that may confront technical, engineering, and design research, as well as outline the general framework we have used in creating our committee.

    Activated protein C resistance (APCR) is a coagulation abnormality often linked to FV Leiden mutation, a single nucleotide G1691A substitution resulting in arginine 506→glutamine missense factor V mutation. FV Leiden has a frequency of 20 to 30% in groups of patients with venous thrombosis while it is of 4 to 10% in normal subjects. FV Leiden is considered as a weak risk factor of thrombosis except in homozygote. FV Leiden is implicated in deep venous thrombosis occurrence. Duration of oral anticoagulant treatment is six months in patients developing a first venous thrombosis except in patients with combined defects or a clinical context suggesting a high risk of severe relapse. Detection of APCR by coagulation methods is often used in first intention with a high specificity if plasmas tested are diluted in factor V deficient plasma. Genotyping study is essential to establish the heterozygote or homozygote statute and certain teams perform it directly. Nevertheless, APCR not related to FV Leiden could be an independent thrombosis risk factor. APCR and FV Leiden are included in laboratory investigations of thrombophilic markers in patients less than 50 years with venous thrombosis. In arterial thrombosis, FV Leiden implication is weak or absent. FV Leiden increases the risk of thrombosis in other situations as in patients with cancer. An association with recurrent miscarriages and other vasculoplacental complications is also reported in many studies but the data concerning the efficacy of antithrombotic treatment to prevent recurrence are currently insufficient.

    The factor (F)V Leiden mutation causes activated protein C (APC) resistance by decreasing the susceptibility of FVa to APC-mediated inactivation and by impairing the APC-cofactor activity of FV in FVIIIa inactivation. However, APC resistance and the risk of venous thromboembolism (VTE) vary widely among FV Leiden heterozygotes. Common F5 genetic variation probably contributes to this variability. APC resistance was determined in 250 FV Leiden heterozygotes and 133 normal relatives using the prothrombinase-based assay, which specifically measures the susceptibility of plasma FVa to APC. The effects of 12 F5 single-nucleotide polymorphisms (SNPs) on the normalized APC sensitivity ratio (nAPCsr) and on FV levels were determined by multiple regression analysis. In FV Leiden heterozygotes,VTE risk increased with increasing nAPCsr, reaching an odds ratio (OR) of 9.9 (95% confidence interval [CI] 1.2–80.5) in the highest nAPCsr quartile. The minor alleles of several F5 SNPs, including 327 A/G (Q51Q), 409 G/C (D79H), 2663 A/G(K830R, T2 haplotype), 6533 T/C (M2120T) and 6755 A/G (D2194G, R2 haplotype), increased the nAPCsr in FV Leiden heterozygotes, but not in their normal relatives. Most of these effects could be attributed to a shift in the FV(Leiden)/normal FV ratio. Four FV Leiden heterozygotes with extremely high nAPCsr turned out to be pseudo-homozygotes, i.e. they carried a deleterious mutation on the non-Leiden allele. In FV Leiden heterozygotes, the prothrombinase-based nAPCsr is a marker of VTE risk and is modulated by common F5 SNPs that affect the FV(Leiden)/normal FV ratio in plasma.

    Full Text Available Objective: to evaluate the impact of Leiden mutation on the course of severe acute pancreatitis. Subjects and methods. One hundred and twelve people were examined. Group 1 comprised 50 patients diagnosed with severe acute pancreatitis without coagulation factor V (Leiden mutation. Group 2 included 42 patients with severe acute pancreatitis who were found to have Leiden mutation. Acute pancreatitis was first diagnosed in both groups. Group 3 consisted of 20 apparently healthy individuals (a control group. The severity of the underlying disease was determined in accordance with the clinical and laboratory parameters recommended by the I. I. Dzhanelidze Saint Petersburg Research Institute of Emergence Care. Results. This investigation revealed an association of Leiden mutation with trends in the development of acute pancreatitis. Group 2 exhibited a more severe disease: large focal pancreatic necrosis was twice more common and infectious complications developed more frequently; more aggressive and radical treatments were more often used. The patients with Leiden mutation had higher mortality rates (33% in the Leiden mutation group and 24% in the non-mutation group. Conclusion. The findings should be kept in mind in elaborating new diagnostic methods and principles in the treatment of the underlying disease and in the prevention of its complications in patients with severe acute pancreatitis. Key words: acute pancreatitis, Leiden mutation.

    Using human evaluation of 100,000 words spread across 24 corpora in 10 languages diverse in origin and culture, we present evidence of a deep imprint of human sociality in language, observing that (i) the words of natural human language possess a universal positivity bias, (ii) the estimated emotional content of words is consistent between languages under translation, and (iii) this positivity bias is strongly independent of frequency of word use. Alongside these general regularities, we describe interlanguage variations in the emotional spectrum of languages that allow us to rank corpora. We also show how our word evaluations can be used to construct physical-like instruments for both real-time and offline measurement of the emotional content of large-scale texts.

    We investigate the response function of human agents as demonstrated by written correspondence, uncovering a new universal pattern for how the reactive dynamics of individuals is distributed across the set of each agent's contacts. In long-term empirical data on email, we find that the set of response times considered separately for the messages to each different correspondent of a given writer, generate a family of heavy-tailed distributions, which have largely the same features for all agents, and whose characteristic times grow exponentially with the rank of each correspondent. We show this universal behavioral pattern emerges robustly by considering weighted moving averages of the priority-conditioned response-time probabilities generated by a basic prioritization model. Our findings clarify how the range of priorities in the inputs from one's environment underpin and shape the dynamics of agents embedded in a net of reactive relations. These newly revealed activity patterns constrain future models of com...

    Livedoid vasculopathy is a rare chronic relapsing disorder characterised by recurrent painful thrombotic and vasculitic ulcers on the legs. We present the cases of two Indian women with livedoid vasculopathy that were found to be associated with an underlying factor V Leiden heterozygous mutation. There were no other thrombotic manifestations, and livedoid vasculopathy was the sole presenting feature of the factor V Leiden mutation, although this could also be coincidental. Initial treatment with high-dose immunosuppressive therapy was suboptimal, and the addition of pentoxifylline and antiplatelet therapy was crucial in achieving disease control and remission. These cases highlight the possible association with an underlying prothrombotic disorder, such as factor V Leiden mutation, in patients with livedoid vasculopathy. Although this association is relatively uncommon, it is more relevant to Indian patients, as the presence of factor V Leiden mutation is highest in this ethnicity as compared to the local Malay and Chinese populations.

    A difference in the prevalence of venous thromboembolism (TE) in major human groups has been described and an uneven distribution of FV Leiden mutation over the world has recently been reported. We investigated FV Leiden mutation in 584 apparently healthy subjects mostly from populations different from those previously investigated: 170 Europeans (Spanish, Italians), 101 sub-saharan Africans (Fon, Bariba, Berba, Dendi), 115 Asians (Indonesians, Chinese, Tharus), 57 Amerindians (Cayapa), 84 Afroamericans (Rio Cayapa, Viche), and 57 Ethiopians (Amhara, Oromo). The mutation was detected in only 1/115 Asian (Tharu) and in 5/170 Europeans (4 Italians, 1 Spanish). These data confirm that in non-Europeans the prevalence of FV mutation is at least 7 times lower than in Europeans and provide indirect evidence of a low prevalence not only of the FV Leiden gene but also of other genes leading to more severe thrombophilia. Finally, findings from the literature together with those pertaining to this study clearly show a marked heterogeneity among Europeans.

    The discovery of the factor V Leiden (FVL) missense mutation (Arg506Gln) causing factor V resistance to the anticoagulant action of activated protein C was a landmark that allowed a better understanding of the basis of inherited thrombotic risk. FVL mutation is currently the most common known hereditary defect predisposing to venous thrombosis. Areas covered: Novel data-driven FVL diagnosis and therapeutic approaches in the management of FVL carriers in various clinical settings. Brief conclusions on topics of direct clinical relevance including currently available indications for primary and secondary prophylaxis, the management of female, pediatric carriers and asymptomatic relatives. Latest evidence on the association between FVL and cancer, as well as the possible use of direct oral anticoagulant therapy. Expert commentary: Although FVL diagnosis nowadays is highly accurate, many doubts remain regarding the best management and therapeutic protocols. The main role of clinicians is to tailor therapeutic strategies to carriers and their relatives. High familial penetrance, distinctive aspects of the first thrombotic event (provoked/unprovoked, age, etc.) and laboratory biomarkers can guide the optimal management of secondary antithrombotic prophylaxis, primary prophylaxis in asymptomatic individuals, and whether to screen relatives.

  16. Heterogeneous ethnic distribution of the factor v leiden mutation

    1999-01-01

    Full Text Available Inherited resistance to activated protein C caused by the factor V Leiden (FVL mutation is the most common genetic cause of venous thrombosis yet described, being found in 20-60% of patients with venous thrombophilia. A relationship between the FVL mutation and an increased predisposition to arterial thrombosis in young women was recently reported. We assessed the prevalence of the FVL mutation in 440 individuals (880 chromosomes belonging to four different ethnic groups: Caucasians, African Blacks, Asians and Amerindians. PCR amplification followed by MnlI digestion was employed to define the genotype. The FVL mutation was found in a heterozygous state in four out of 152 Whites (2.6%, one out of 151 Amerindians (0.6%, and was absent among 97 African Blacks and 40 Asians. Our results confirm that FVL has a heterogeneous distribution in different human populations, a fact that may contribute to geographic and ethnic differences in the prevalence of thrombotic diseases. In addition, these data may be helpful in decisions regarding the usefulness of screening for the FVL mutation in subjects at risk for thrombosis.

    To assess the rate of early (first trimester) and late (second and third trimester) fetal loss in women who are factor V Leiden homozygous. Between December 1995 and February 2007, consecutive, unrelated white women who were factor V Leiden homozygous and who had been pregnant at least once were recruited from 10 French hemostasis units. For reasons of comparison, we included women who were factor V Leiden heterozygous and a group of noncarriers. The frequency of early and late fetal loss was assessed retrospectively and compared among the three groups. The effect of concomitant thrombophilic abnormalities was evaluated. The overall pregnancy outcome was reported. We analyzed 240 thromboprophylaxis-free pregnancies in 95 women who were factor V Leiden homozygous, 425 in 195 women who were factor V Leiden heterozygous, and 182 in 73 women who were noncarriers. The risk of late fetal loss was higher in women who were homozygous (13/95, 13.7%) compared with those who were noncarriers (1/73, 1.4%, odds ratio 11.41, 95% confidence interval 1.46-89.46, P=.002), whereas it was similar in women who were heterozygous and in noncarriers (6/195, 3.1% compared with 1/73, 1.4%, P=.68). The percentage of women with early fetal loss was similar in the three groups (P=.81). The live-birth rate was 80%, 84%, and 85%, respectively, for women who where homozygous, heterozygous, and noncarriers (P=.88). The factor V Leiden homozygous genotype increases the risk of late fetal loss. However, the overall likelihood of a positive outcome is high in our series of women who were homozygous. III.

  1. Anticoagulation duration in heterozygous factor V Leiden: a decision analysis.

    2013-01-01

    Current anticoagulation guidelines suggest that optimal anticoagulation duration for unprovoked venous thromboembolism is determined by an individual risk assessment, balancing risks of anticoagulation bleeding with venous thromboembolism recurrence. Among individuals heterozygous for the factor V Leiden mutation, while venous thromboembolism recurrence risk is greater, the risk for bleeding is recognized to be lower, suggesting longer duration anticoagulation could be considered. The objective of this study was to compare standard vs. lifelong anticoagulation in 20-year-old factor V Leiden heterozygotes with unprovoked venous thromboembolism. A Markov state-transition model was used, incorporating risks of major, minor, and fatal anticoagulation bleeding, bleeding and thromboembolism morbidity and mortality, and quality of life utilities. Model parameter values favoring lifelong anticoagulation in factor V Leiden heterozygotes were determined in sensitivity analyses. Outcomes were in quality-adjusted life years, discounted at 3% per year. In general population groups with odds ratios for venous thromboembolism recurrence and anticoagulation bleeding of 1.0, a short-term anticoagulation strategy gained 0.09 quality-adjusted life years more than a lifelong anticoagulation strategy. By contrast, in factor V Leiden heterozygotes, lifetime anticoagulation was favored if their relative risk of venous thromboembolism was greater than 1.07 or their relative risk for bleeding was less than 0.91. Results were relatively insensitive to individual variation in other parameter values. Lifelong anticoagulation may benefit individuals heterozygous for factor V Leiden and previous idiopathic venous thromboembolism. Studies assessing bleeding risk with anticoagulation in factor V Leiden heterozygotes and the costs of indefinite anticoagulation are needed to determine if lifelong anticoagulation is the optimal strategy. © 2013 Elsevier Ltd.

    Activated proteinC resistance is a frequent prothrombotic abnormality. In most cases it is due to factorV Leiden mutation by nucleotide G1691A substitution. This recently described thrombophilic defect of activated proteinC resistance has been postulated to be implicated in the pathogenesis of idiopathic intracranial hypertension (IIH).

    Factor V Leiden (FVL) supposedly carries relatively higher risk of deep vein thrombosis (DVT), compared to the risk of pulmonary embolism (PE). To prove this paradox in a group of patients with various clinical presentation of venous thromboembolism (VTE). We retrospectively evaluated clinical pattern of VTE in patients who had been referred to vascular clinic shortly after an acute VTE event. In FVL positive and FVL negative groups we compared the prevalence of isolated symptomatic DVT (proximal or distal) and symptomatic PE with/without DVT, and, moreover, asymptomatic DVT or PE. Of 575 patients (mean age 57 years, 50.1% women), 120 were FVL positive and those had significantly higher prevalence of isolated symptomatic DVT, compared to symptomatic PE with/without DVT. Proximal DVT location was significantly more frequent in FVL carriers. The prevalence of asymptomatic PE did not differ between the two groups. The rate of asymptomatic DVT tended to be higher in FVL negative group. In a multivariate analysis, we confirmed FVL to be positively associated with isolated DVT presentation (odds ratio OR 1.757; 95% confidence interval (CI) 1.148-2.690). On the contrary, increasing age and unprovoked nature of VTE event carried a higher risk of symptomatic PE. We confirmed FVL to be significantly associated with isolated symptomatic DVT despite higher prevalence of proximal DVT in FVL carriers. The fact of relatively lower risk of PE in FVL positive patients might have clinical implication. However, mechanisms of FVL paradox remain to be elucidated. © The Author 2014.

    Factor V G1691A (FV Leiden), FII GA20210, and methylenetetrahydrofolate reductase (MTHFR) C677T mutations are the most common genetic risk factors for thromboembolism in the Western countries. However, there is rare data in Iran about cerebral venous and sinus thrombosis (CVST) patients. The aim of this study was to evaluate the frequency of common genetic thrombophilic factors in CVST patients. Forty consequently CVST patients from two University Hospital in Isfahan University of Medical Sciences aged more than 15 years from January 2009 to January 2011 were recruited. In parallel, 51 healthy subjects with the same age and race from similar population selected as controls. FV Leiden, FII GA20210, MTHFR C677T, and FV Cambridge gene mutations by polymerase chain reaction technique were evaluated in case and control groups. FV Leiden, FII GA20210, and FV Cambridge gene mutations had very low prevalence in both case (5%, 2%, 0%) and control (2.5%, 0%, 0%) and were not found any significant difference between groups. MTHFR C677T mutations was in 22 (55%) of patients in case group and 18 (35.5%) of control group (P = 0.09). This study showed that the prevalence of FV Leiden, FII GA20210, and FV Cambridge were low. Laboratory investigations of these mutations as a routine test for all patients with CVST may not be cost benefit.

    Factor V Leiden, Prothrombin and MTHFR gene mutation, could have an influence in pregnancy with adverse outcome Preeclamsia, IUGR and Placental abruption. The aim of this study is to investigate the presence of above mentioned inherited thrombophilias and its statistical significance, distribution among the complicated and normal pregnancy, and relative risk for carrier of mutation to develop preeclampsia, IUGR and placental abruption. Prospective cohort study is implemented at University Clinic for Obstetric and Gynecology in Skopje, Republic of Macedonia. The study included 109 delivered patients: 40 with preeclapmsia, 22 with IUGR, 17 with placental abruption and 30 as control group with normal pregnancy. The amount of 3 ml venous blood has been used for detection of these point mutations using ThromboStrip -Opegen, QIAGEN kit manufactured for thrombotic risk. The highest frequency was found: in the group with preeclampsia 35% were MTHFR homozygous, IUGR -MTHFR heterozygous 45%, Placental abruption- 52.9% MTHFR heterozygous, and in the control group without thrombophilia 56.7%. There were combined thrombophilia in 3 patients. There aren`t statistical significance in presence of thrombophilia among groups (p > 0.05). Statistical significance (p Factor V Leiden heterozygous was 4.50 (0.47Factor V Leiden for placental abruption. Further investigations with more patients are warranted.

    Full Text Available The concept of human rights has evolved in its essence as physical force was gradually replaced by reason, as in society took shape legal principles that would become fundamental: the principle of freedom, equality, solidarity, etc.. Fundamental human rights are a set of rights, freedoms and duties recognized worldwide covering essential issues for human development, welfare and progress. Over time, the human rights institution has evolved and undergone important correctives from one historical arrangement to another and bet on the same order, from one stage to another.

    A capacity for nonverbal numerical estimation is widespread among humans and animals. However, it is currently unclear whether numerical percepts are spontaneously extracted from the environment and whether nonverbal perception is influenced by human exposure to formal mathematics. We tested US adults and children, non-human primates, and numerate and innumerate Tsimane' adults on a quantity task in which they could choose to categorize sets of dots on the basis of number alone, surface area alone or a combination of the two. Despite differences in age, species and education, subjects are universally biased to base their judgments on number as opposed to the alternatives. Numerical biases are uniquely enhanced in humans compared to non-human primates, and correlated with degree of mathematics experience in both the US and Tsimane' groups. We conclude that humans universally and spontaneously extract numerical information, and that human nonverbal numerical perception is enhanced by symbolic numeracy. PMID:28091519

    Factor V Leiden is the most common inherited trait in Caucasians that predisposes individuals to venous thrombosis. However, it is almost absent amongst the Basque people that live in the south western part of Europe. To explain this finding, we speculate upon the putative contribution of various evolutionary forces through which the Basque genome may have been shaped. © 2015 International Society on Thrombosis and Haemostasis.

    Full Text Available ABSTRACT: Introduction & Objective: Factor V Leiden and prothrombin mutation are not common but they are involved in pediatric thrombosis. The aim of this study was to evaluate the frequency of factor V Leiden & prohtrombin mutation in healthy population of Shiraz, south of Iran. Materials & Methods: In this cross-sectional study 195 healthy people (97 female and 98 male were randomly selected. Peripheral white blood cells obtained from 5 ml blood contained 1-2 mg/ml K2- EDTA. Genomic DNA extraction was performed following the protocol described by Miller et al. PCR amplification was carried out in 25μl reaction volume containing 0.5 units Taq polymerase, 200μM dNTP, 500 μM of each of the previously described primers. After initial denaturation, 35 cycles at 95◦c for 30s, and 72◦c for 20s and followed extention by 72 for 10 min were performed. About 10μl of PDR product was digested with MNI I or Mbo restriction enzymes. Results: In this study we determined factor V Leiden in 8 (4.1% and prothrombin mutation in 6 individual (3.07% of 198 cases in heterozygous form. No homozygous was seen for any of the mutations. Only one case presented a double heterozygous for factor V and prothrombin in this cohort. Conclusion: Several studies of factor V leiden and prothrombin mutations in the East of Asia showed the higher frequency of these mutations in Iran.

  17. Personality trait structure as a human universal.

    1997-05-01

    Patterns of covariation among personality traits in English-speaking populations can be summarized by the five-factor model (FFM). To assess the cross-cultural generalizability of the FFM, data from studies using 6 translations of the Revised NEO Personality Inventory (P.T. Costa & R. R. McCrae, 1992) were compared with the American factor structure. German, Portuguese, Hebrew, Chinese, Korean, and Japanese samples (N = 7,134) showed similar structures after varimax rotation of 5 factors. When targeted rotations were used, the American factor structure was closely reproduced, even at the level of secondary loadings. Because the samples studied represented highly diverse cultures with languages from 5 distinct language families, these data strongly suggest that personality trait structure is universal.

  19. Universal growth constraints of human systems

    CERN Document Server

    Hébert-Dufresne, Laurent; Young, Jean-Gabriel; Dubé, Louis J

    2013-01-01

    Scale independence is a ubiquitous feature of complex systems which implies a highly skewed distribution of resources with no characteristic scale. Research has long focused on why systems as varied as protein networks, evolution and stock actions all feature scale independence. Assuming that they simply do, we focus here on describing exactly how this behavior emerges. We show that growing towards scale independence implies strict constraints: the first is the well-known preferential attachment principle and the second is a new form of temporal scaling. These constraints pave a precise evolution path, such that an instantaneous snapshot of a distribution is enough to reconstruct its past and to predict its future. We validate our approach on diverse spheres of human activities ranging from scientific and artistic productivity, to sexual relations and online traffic.

  20. Statistical universals reveal the structures and functions of human music.

    Savage, Patrick E; Brown, Steven; Sakai, Emi; Currie, Thomas E

    2015-07-21

    Music has been called "the universal language of mankind." Although contemporary theories of music evolution often invoke various musical universals, the existence of such universals has been disputed for decades and has never been empirically demonstrated. Here we combine a music-classification scheme with statistical analyses, including phylogenetic comparative methods, to examine a well-sampled global set of 304 music recordings. Our analyses reveal no absolute universals but strong support for many statistical universals that are consistent across all nine geographic regions sampled. These universals include 18 musical features that are common individually as well as a network of 10 features that are commonly associated with one another. They span not only features related to pitch and rhythm that are often cited as putative universals but also rarely cited domains including performance style and social context. These cross-cultural structural regularities of human music may relate to roles in facilitating group coordination and cohesion, as exemplified by the universal tendency to sing, play percussion instruments, and dance to simple, repetitive music in groups. Our findings highlight the need for scientists studying music evolution to expand the range of musical cultures and musical features under consideration. The statistical universals we identified represent important candidates for future investigation.

    Full Text Available The article argues for the universal character of human rights. It is demonstrated that they are not of specific value of Western culture but are a universal norm. This norm is valid not only for political practices but, first of all, for the morality and practice of argumentation. Human rights are strictly correlated with Kantian Categorical Imperative and can be substantiated by means of transcendental­pragmatic argument (K.­O. Apel. The difference between values and norms are also considered. It is demonstrated that values are always subjective and arbitrary meanwhile final justification is possible for norms.

    The most common forms of familial thrombophilia are factor V Leiden (FVL) and prothrombin mutation (PTM). Homozygous FVL and PTM have long been feared conditions thought to cause high rates of morbidity and mortality. To analyse clinical features in patients with homozygous FVL and PTM, as well as patients with double heterozygosity for FVL and PTM. All patients with homozygous FVL, PTM or double heterozygosity in the MATS database of 1465 consecutive unselected patients were analysed regarding age at inclusion venous thromboembolism (VTE), age at first thrombosis, recurrence, clinical course and acquired risk factors. We found 36 patients homozygous for FVL. Patients homozygous for FVL were younger than controls at group level (56 ± 18 vs. 63 ± 17, p < 0.02). Homozygous women were younger than female controls (50 ± 19 vs. 63 ± 18, p < 0.002). No difference was observed when comparing male subjects. Women were younger than men at inclusion thrombosis (50 ± 19 vs. 65 ± 14, p < 0.02) and at first thrombosis (47 ± 19 vs. 64 ± 14, p < 0.01). Deep venous thrombosis (DVT) was seen in 33 patients (92 %), 6 (17 %) had pulmonary embolism (PE) and 3 (8 %) had combined DVT and PE. PE was less frequent in homozygous FVL women compared to female controls (p < 0.03). VTE recurred in 3 subjects during the duration of the study. Odds ratio for VTE in homozygous FVL patients compared to controls was 13.9 (95 % CI 9.9-19.7). We found no subjects with homozygous PTM. Double heterozygosity for FVL and PTM was seen in 12 subjects. There was no difference in age at inclusion VTE between double heterozygotes and controls (59 ± 16 vs. 63 ± 17, ns.). DVT was seen in 92 % at inclusion, 8 % had PE. Mean age at first VTE was 52 ± 17 (27-82). Consecutive homozygous FVL patients had a higher age at first thrombosis than previously described. Homozygous females are affected at an earlier age than homozygous men and female controls. It seems that

  3. Reconciling female genital circumcision with universal human rights.

    2017-09-18

    One of the most challenging issues in cross-cultural bioethics concerns the long-standing socio-cultural practice of female genital circumcision (FGC), which is prevalent in many African countries and the Middle East as well as in some Asian and Western countries. It is commonly assumed that FGC, in all its versions, constitutes a gross violation of the universal human rights of health, physical integrity, and individual autonomy and hence should be abolished. This article, however, suggests a mediating approach according to which one form of FGC, the removal of the clitoris foreskin, can be made compatible with the high demands of universal human rights. The argument presupposes the idea that human rights are not absolutist by nature but can be framed in a meaningful, culturally sensitive way. It proposes important limiting conditions that must be met for the practice of FGC to be considered in accordance with the human rights agenda. © 2017 John Wiley & Sons Ltd.

    2015-01-01

    Full Text Available Human development is the basis of social progress in the modern world. University education has an important role in the formation of human capital. The form of human capital has tangible and intangible investments. Intangible investment is higher education. The aim of the article is to show the formation of the human capital in university education. The modern university is a dynamic category, aimed at training competent mobile specialists ready to continuous self-education, self-improvement and self-development. New educational environment determines unified laws in management of industrial enterprises, businesses, and educational institutions. Modern university educational process implies certain freedom of students and teachers in selection of training methods, forms of monitoring and evaluation of competencies, as well as the choice of tasks for independent work, enhancing the development of students’ competencies, which are formed individually. This creates difficulty in assessing the formation of competences, which can be made based on the results of the rating, examinations and results of online exams on the studied discipline, as well as by forming a portfolio that reflects the qualitative aspect of the assessment of a student’s progress.

    2011-07-01

    Two cases are reported of flap loss following microsurgical perforator flap breast reconstruction in patients diagnosed with a factor V Leiden mutation. Factor V Leiden is the most common inherited cause of hypercoagulability, leading to an increased risk of thrombotic events. The first patient underwent a deep inferior epigastric artery perforator flap and then had recurrent arterial thrombosis both intraoperatively and postoperatively. This patient was subsequently diagnosed with a factor V Leiden mutation. The second patient had a known factor V Leiden mutation and underwent a superior gluteal artery perforator flap, which developed thrombosis and flap loss 2 days later. Preoperative assessment of a personal or family history of unexplained venous or arterial thrombosis should prompt suspicion of a factor V Leiden mutation. This mutation places patients at high risk for thromboembolic events in microvascular breast reconstruction, particularly when oral contraceptives or tamoxifen are used in conjunction.

    Activated protein C resistance assays can detect factor V Leiden with high accuracy, depending on the method used. Factor Xa inhibitors such as rivaroxaban and direct thrombin inhibitors including dabigatran, argatroban, and bivalirudin can cause falsely normal results. Lupus anticoagulants can cause incorrect results in most current assays. Assays that include dilution into factor V-deficient plasma are needed to avoid interference from factor deficiencies or elevations, which can arise from a wide variety of conditions such as warfarin, liver dysfunction, or pregnancy. The pros and cons of the currently available assays are discussed. © 2014 Wiley Periodicals, Inc.

    1999-01-01

    The United States takes a highly relativistic stance toward the Universal Declaration of Human Rights. It regards the socio-economic rights and the right to development as without status; exempts itself from all provisions of the Declaration by failing to sign the conventions designed to implement these provisions; and unilaterally qualifies its support of civil and political rights. Leading recipients of U.S. aid have traditionally included regimes with atrocious human rights records. Those struggling for human rights should have no illusions about the systems of power and their servants.

    2006-01-01

    Aim To determine the prevalence of factor V Leiden mutation in patients with different presentation of venous thromboembolic disease and healthy individuals in the Republic of Macedonia. Methods The retrospective case-control study involved 190 patients with venous thromboembolic disease and 200 healthy individuals, who were screened for the presence of factor V Leiden mutation, using a polymerase chain reaction-restriction fragment length polymorphism method. The prevalence of factor V Leiden was analyzed according to the localization of thrombosis, presence of risk factors, and family history of thrombosis. The odds of deep venous thrombosis were calculated with respect to the presence of factor V Leiden mutation. Results The prevalence of factor V Leiden mutation among patients with venous thromboembolic disease was 21.1%, compared with 5.5% in the healthy individuals. Factor V Leiden positive patients had the first episode of deep venous thrombosis at a younger age, and the prevalence of the mutation was the highest among patients with a positive family history of thrombosis (33.9%, P = 0.003) and in patients with deep venous thrombosis affecting a large blood vessel (37.7%, P = 0.001). The prevalence of factor V Leiden mutation was lower in patients with calf deep venous thrombosis and primary thromboembolism (13.3% and 13.1%, respectively; P>0.05). The odds ratio for iliofemoral or femoral deep venous thrombosis in factor V Leiden carriers was 10.4 (95% confidence interval, 4.7-23.1). Conclusion The prevalence of factor V Leiden mutation was high in patients with venous thromboembolic disease and healthy individuals in the Republic of Macedonia. Factor V Leiden carriers have the highest odds of developing deep venous thrombosis affecting a large venous blood vessel. PMID:16758522

    2015-01-01

    How universal is human conceptual structure? The way concepts are organized in the human brain may reflect distinct features of cultural, historical, and environmental background in addition to properties universal to human cognition. Semantics, or meaning expressed through language, provides direct access to the underlying conceptual structure, but meaning is notoriously difficult to measure, let alone parameterize. Here we provide an empirical measure of semantic proximity between concepts using cross-linguistic dictionaries. Across languages carefully selected from a phylogenetically and geographically stratified sample of genera, translations of words reveal cases where a particular language uses a single polysemous word to express concepts represented by distinct words in another. We use the frequency of polysemies linking two concepts as a measure of their semantic proximity, and represent the pattern of such linkages by a weighted network. This network is highly uneven and fragmented: certain concepts ...

  16. Medical humanities and philosophy: is the universe expanding or contracting?

    Science.gov (United States)

    Stempsey, William E

    2007-12-01

    The question of whether the universe is expanding or contracting serves as a model for current questions facing the medical humanities. The medical humanities might aptly be described as a metamedical multiverse encompassing many separate universes of discourse, the most prominent of which is probably bioethics. Bioethics, however, is increasingly developing into a new interdisciplinary discipline, and threatens to engulf the other medical humanities, robbing them of their own distinctive contributions to metamedicine. The philosophy of medicine considered as a distinct field of study has suffered as a result. Indeed, consensus on whether the philosophy of medicine even constitutes a legitimate field of study is lacking. This paper presents an argument for the importance of a broad conception of the philosophy of medicine and the central role it should play in organizing and interpreting the various fields of study that make up the metamedical multiverse.

  17. Universality of Man as a Cultural and Historical Human Being

    Directory of Open Access Journals (Sweden)

    S. Z. Gontcharov

    2012-01-01

    Full Text Available On the grounds of theoretical synthesis, the paper reveals the phenomenon of human being in its creative dimension. The present research is aimed at exploring the prospective opportunities for academic processes. The basics of universal essence of man as a cultural historic being with unlimited potential of self- development are defined; the man being mirrored by the basic philosophic concepts: naturalistic, orthodox-oriented, bio-social or bio-socio-cultural. There are two opposing views on human nature: the anthropological essentialism holding that individuality is predetermined by essence; and the anthropological existentialism claiming the opposite – human existence precedes the essentiality, the latter being constituted by the acts of choice, self-development and self-responsibility for personal choice and projecting. In the first case, the subjective side of human existence is ignored, while in the second – the objective socially conditioned side is left behind. Both theories are antihistorical as it is the history that conditions the essence of man according to the ancestral determination, the latter being modified by way of human activity and communication in a particular historical period. The components of human universal essence are defined as follows: possession of organic body, social heritage, free will, self-activity, creativity, social and rational human nature, absence of antagonistic programs of social behavior. According to the author, for the adequate realization of human universality, it is necessary to move from the profit oriented speculative market economy to the creative one oriented on social effectiveness, quality of life and reproduction of wholesome individuals. The research output can be used for devising the methodology of philosophic and pedagogic anthropology, as well as pedagogic practices of teaching philosophy and pedagogic theory in higher school.

    Factor V Leiden (F5(L) ) is a common genetic risk factor for venous thromboembolism in humans. We conducted a sensitized N-ethyl-N-nitrosourea (ENU) mutagenesis screen for dominant thrombosuppressor genes based on perinatal lethal thrombosis in mice homozygous for F5(L) (F5(L/L) ) and haploinsufficient for tissue factor pathway inhibitor (Tfpi(+/-) ). F8 deficiency enhanced the survival of F5(L/L)Tfpi(+/-) mice, demonstrating that F5(L/L)Tfpi(+/-) lethality is genetically suppressible. ENU-mutagenized F5(L/L) males and F5(L/+)Tfpi(+/-) females were crossed to generate 6,729 progeny, with 98 F5(L/L)Tfpi(+/-) offspring surviving until weaning. Sixteen lines, referred to as "modifier of Factor 5 Leiden (MF5L1-16)," exhibited transmission of a putative thrombosuppressor to subsequent generations. Linkage analysis in MF5L6 identified a chromosome 3 locus containing the tissue factor gene (F3). Although no ENU-induced F3 mutation was identified, haploinsufficiency for F3 (F3(+/-) ) suppressed F5(L/L)Tfpi(+/-) lethality. Whole-exome sequencing in MF5L12 identified an Actr2 gene point mutation (p.R258G) as the sole candidate. Inheritance of this variant is associated with suppression of F5(L/L)Tfpi(+/-) lethality (P = 1.7 × 10(-6)), suggesting that Actr2(p.R258G) is thrombosuppressive. CRISPR/Cas9 experiments to generate an independent Actr2 knockin/knockout demonstrated that Actr2 haploinsufficiency is lethal, supporting a hypomorphic or gain-of-function mechanism of action for Actr2(p.R258G) Our findings identify F8 and the Tfpi/F3 axis as key regulators in determining thrombosis balance in the setting of F5(L) and also suggest a role for Actr2 in this process.

    Is the thrombophilia mutation factor V Leiden (FVL) associated with an increased total sperm count? Carriers of FVL have a higher total sperm count than non-FVL-carriers, which could not be explained by genetic linkage or by observations in a FVL-mouse model. FVL has a high prevalence in Caucasians despite detrimental health effects. Carriers have been shown to have higher fecundity, which might partly explain this evolutionary paradox. We determined FVL status in two cohorts (Dutch, n = 627; Danish, n = 854) of consecutively included men without known causes for spermatogenic failure, and performed an individual patient data meta-analysis of these two cohorts together with one previously published (Dutch, n = 908) cohort. We explored possible biological underpinnings for the relation between sperm count and FVL, by use of a FVL-mouse model and investigations of genetic linkage. Participants were male partners of subfertile couples (two Dutch cohorts) and young men from the general population (Danish cohort): FVL carrier rate was 4.0%, 4.6% and 7.3%, respectively. There were differences in smoking, abstinence time and age between the cohorts. We corrected for these in the primary analysis, which consisted of a mixed linear effects model, also incorporating unobjectified population differences. In public haplotype data from subjects of European descent, we explored linkage disequilibrium of FVL with all known single nucleotide polymorphisms in a 1.5 MB region around the F5 gene with an R2 cutoff of 0.8. We sequenced exons of four candidate genes hypothesized to be linked to FVL in a subgroup of FVL carriers with extreme sperm count values. The animal studies consisted of never mated 15-18-week-old C57BL/J6 mice heterozygous and homozygous for FVL and wild-type mice. We compared spermatogenesis parameters (normalized internal genitalia weights, epididymis sperm content and sperm motility) between FVL and wild-type mice. Human FVL carriers have a higher total sperm

    Recent work has stressed the importance of the concept of solidarity to bioethics and social philosophy generally. But can and should it feature in documents such as the Universal Declaration on Bioethics and Human Rights as anything more than a vague notion with multiple possible interpretations? Although noting the tension between universality and particularity that such documents have to deal with, and also noting that solidarity has a political content, the paper explores the suggestion that solidarity should feature more centrally in international regulations. The paper concludes with the view that when solidarity is seen aright, the UDBHR is an implicitly solidaristic document.

    Full Text Available Objectives. Presence of a factor-V Leiden mutation in a patient with myotonic dystrophy type 1 (DM1 has been reported only once. Here we report the second DM1 patient carrying a factor-V mutation who died from long-term complications of this mutation. Case Report. A 66-year-old DM1 patient with multi-organ-disorder syndrome developed a first deep venous thrombosis (DVT and consecutive pulmonary embolism (PE at age 50 y. Acetyl-salicylic acid was given. One year later he experienced a second DVT; that is why phenprocoumon was started. Despite anticoagulation, he experienced a third DVT bilaterally and a second PE bilaterally at 61 y; that is why a vena cava filter was additionally deployed. Despite therapeutic anticoagulation, he experienced a vena cava filter thrombosis at age 62 y. Genetic workup revealed a heterozygous factor-V mutation in addition to a CTG-repeat expansion of 500. As a consequence of PE he developed chronic obstructive pulmonary disease and experienced recurrent pulmonary infections, which were lastly responsible for decease at age 66 y despite intensive care measures. Conclusion. The heterozygous Leiden mutation may severely affect DM1 patients to such a degree that they die from its complications. If DM1 patients present with unusual manifestations, search for causes other than a CTG-repeat expansion is indicated.

    How universal is human conceptual structure? The way concepts are organized in the human brain may reflect distinct features of cultural, historical, and environmental background in addition to properties universal to human cognition. Semantics, or meaning expressed through language, provides indirect access to the underlying conceptual structure, but meaning is notoriously difficult to measure, let alone parameterize. Here, we provide an empirical measure of semantic proximity between concepts using cross-linguistic dictionaries to translate words to and from languages carefully selected to be representative of worldwide diversity. These translations reveal cases where a particular language uses a single "polysemous" word to express multiple concepts that another language represents using distinct words. We use the frequency of such polysemies linking two concepts as a measure of their semantic proximity and represent the pattern of these linkages by a weighted network. This network is highly structured: Certain concepts are far more prone to polysemy than others, and naturally interpretable clusters of closely related concepts emerge. Statistical analysis of the polysemies observed in a subset of the basic vocabulary shows that these structural properties are consistent across different language groups, and largely independent of geography, environment, and the presence or absence of a literary tradition. The methods developed here can be applied to any semantic domain to reveal the extent to which its conceptual structure is, similarly, a universal attribute of human cognition and language use.

Furthermore, hemophiliac patients have an increased risk of severe life-threatening hemorrhage, blood transfusions, and therefore hepatitis transmission, mainly hepatitis C (HCV.Aims and methods: We present a 54-year-old male with a 5-year history of decompensated liver cirrhosis on the grounds of HCV hepatitis, hemophilia A, and thrombophilia V Leiden. He was admitted to our department because of severe abdominal distension, resembling ‘tense ascites’ despite the use of diuretics. Clinical examination showed shifting dullness and a protuberant abdomen, while hematological and blood chemistry results revealed thrombopenia (platelets: 77000/mL and hypoalbuminemia. Repeated abdominal paracentesis (under factor VIII administration failed to remove ascitic fluid, while abdominal echosonography and computed tomography revealed severe edema of mesenterium and intraabdominal viscus and the absence of free ascitic fluid, atrophic cirrhotic liver, and splenomegaly. Moreover, abdominal doppler echosonography revealed signs of portal hypertension, previous portal vein thrombosis, and revascularization of the portal vein. Gastroscopy showed esophageal varices grade II, without signs of bleeding. A-FP and all other laboratory examinations were normal.Results: Our patient was intravenously treated with albumine and diuretics (furosemide with mild improvement of his abdominal distension. During his hospitalization he presented an episode of spontaneous bacterial peritonitis and hepatic encephalopathy, which were successfully treated with lactulose clysmas and ciprofloxacine.

    Inoue, Hiroshi

    Under the globalized economy, Japanese corporations compete with rivals of the western countries and emerging economies. And domestically, they face with deflation, falling birth-rate, an aging society, and shrinking market. So they need to foster and retain global-minded human resources who can play an active role in global business, and who can drive innovation. What Japanese corporations expect for global-minded human resources are ability to meet challenges, ability to think independently free from conventional wisdom, communication skills in foreign languages, interests in foreign cultures and different values, and so on. In order to foster global-minded human resources, Keidanren work with the 13 universities selected under the Japanese Government‧s “Global 30” projects to undertake “Global-minded Human Resources Development Projects” .

  6. Human Rights and the Political Economy of Universal Health Care

    Science.gov (United States)

    2016-01-01

    Abstract Health system financing is a critical factor in securing universal health care and achieving equity in access and payment. The human rights framework offers valuable guidance for designing a financing strategy that meets these goals. This article presents a rights-based approach to health care financing developed by the human right to health care movement in the United States. Grounded in a human rights analysis of private, market-based health insurance, advocates make the case for public financing through progressive taxation. Financing mechanisms are measured against the twin goals of guaranteeing access to care and advancing economic equity. The added focus on the redistributive potential of health care financing recasts health reform as an economic policy intervention that can help fulfill broader economic and social rights obligations. Based on a review of recent universal health care reform efforts in the state of Vermont, this article reports on a rights-based public financing plan and model, which includes a new business tax directed against wage disparities. The modeling results suggest that a health system financed through equitable taxation could produce significant redistributive effects, thus increasing economic equity while generating sufficient funds to provide comprehensive health care as a universal public good.

    We analyse the all-sky Leiden/Argentina/Bonn HI survey, where we identify shells belonging to the Milky Way. We used an identification method based on the search of continuous regions of a low brightness temperature that are compatible with given properties of HI shells. We found 333 shells in the whole Galaxy. The size distribution of shells in the outer Galaxy is fitted by a power law with the coefficient of 2.6 corresponding to the index 1.8 in the distribution of energy sources. Their surface density decreases exponentially with a scale length of 2.8 kpc. The surface density of shells with radii >= 100 pc in the solar neighbourhood is around 4 per kpc^2 and the 2D porosity is approximately 0.7.

  10. The relationship between FV Leiden and pulmonary embolism

    Hooper W Craig

    2001-11-01

    Full Text Available Abstract Pulmonary embolism (PE is one of the leading causes of in-patient hospital deaths. As a consequence, the identification of hemostatic variables that could identify those at risk would be important in reducing mortality. It has previously been thought that deep vein thrombosis and PE are a single disease entity and would, therefore, have the same risk factors. This view is changing, however, with the realization that the prevalence of FV Leiden, a recognized genetic risk factor for deep vein thrombosis, may be a 'milder' genetic risk factor for PE. These observations suggest that PE is not only associated with a different set of risk factors, but may be reflective of a different clot structure.

    Full Text Available In this paper, an analysis of the technical efficiency in the formation of 2,236 graduates in 1998 in the University of Florence, that is, in the university human capital formation, is performed, by modelling the production process as one in which the student produces himself as a graduate. The tool utilized is the DEA methodology, under the hypothesis of variable returns to scale. The production factors are represented by a set of human and capital resources provided by the faculties, along with individual factors represented by secondary school diploma score and by the length of university study. The analysis is conducted both for the overall graduates, and at a faculty level, in order to emphasize the contribution provided by the latter to efficiency. There is evidence that the students graduated with an average efficiency greater than 90% and therefore with an unexploited productive capacity lower than 10%. At a faculty level, Formation Science appears to be the most efficient, whereas Economics is the less efficient one. By and large, the contribution to efficiency provided by faculties is greater than that brought by students individual characteristics.

  12. Factor V Leiden in women: a thrombotic risk factor or an evolutionary advantage?

    Franchini, Massimo; Lippi, Giuseppe

    2011-04-01

    Factor V Leiden is a common gain-of-function gene mutation resulting in a genetic predisposition to thromboembolic complications. Growing evidence in the literature indicates an interaction between factor V Leiden thrombophilia and acquired prothrombotic conditions such as contraceptive use or hormone replacement therapy, resulting in an increased risk of venous thromboembolism (VTE). Similarly, when combined with the prothrombotic influence of pregnancy, women who are carriers of factor V Leiden are faced with an increased risk of adverse pregnancy outcomes, including VTE, pre-eclampsia, fetal loss, placental abruption, and fetal growth restriction. The results of the most important meta-analyses on the relationship between inherited (factor V Leiden) and acquired thrombophilia in women are analyzed in this review, along with the possible evolutionary role of this mutation. © Thieme Medical Publishers.

    To estimate whether there is a correlation between family history of venous thromboembolism and factor V Leiden mutation carriage in gravid women without a personal history of venous thromboembolism. This is a secondary analysis of a prospective observational study of the frequency of pregnancy-related thromboembolic events among carriers of the factor V Leiden mutation. Family history of venous thromboembolism in either first- or second-degree relatives was self-reported. Sensitivity, specificity, and positive and negative predictive values of family history to predict factor V Leiden mutation carrier status were calculated. Women without a personal venous thromboembolism history and with available DNA were included (n=5,168). One hundred forty women (2.7% [95% confidence interval (CI) 2.3-3.2%]) were factor V Leiden mutation-positive. Four hundred twelve women (8.0% [95% CI 7.3-8.7%]) reported a family history of venous thromboembolism. Women with a positive family history were twofold more likely to be factor V Leiden mutation carriers than those with a negative family history (23 of 412 [5.6%] compared with 117 of 4,756 [2.5%], Pfactor V Leiden carriers were 16.4% (95% CI 10.7-23.6%), 92.3% (95% CI 91.5-93.0%), and 5.6% (95% CI 3.6-8.3%), respectively. Although a family history of venous thromboembolism is associated with factor V Leiden mutation in thrombosis-free gravid women, the sensitivity and positive predictive values are too low to recommend screening women for the factor V Leiden mutation based solely on a family history.

    2010-09-01

    Full Text Available This contribution asks, in an empirical rather than formal perspective, whether a range of descriptive phenomena in grammar usually characterized in terms of ‘recursion’ actually exhibit recursion. It is concluded that empirical evidence does not support this customary assumption. Language, while formally recursive, need not be recursive in the underlying generative mechanisms of its grammar. Hence, while recursion may well be one of the hallmarks of human nature, grammar may not be the cognitive domain where it is found. Arguments for this claim are briefly exposed and then discussed with respect to a selection of talks from the DGfS workshop on Foundations of Language Comparison: Human Universals as Constraints on Language Diversity that led to this special issue.

    This article argues that the art collection owned by Franciscus dele Boë, Sylvius, a professor of practical medicine at the University of Leiden from 1658 to 1672, gives insight into some aspects of the character and significance of the new philosophy in the midseventeenth century. Through his teaching, his advocacy, and his practice of the new experimental philosophy, Sylvius played a role in shaping and institutionalizing the practices of the new philosophy that spread throughout Europe in the late seventeenth and eighteenth centuries. Sylvius's house design and large painting collection also exemplified the consumption and taste of the northern Netherlands in the seventeenth century. An examination of both Sylvius's science and his taste can help us understand what was at stake for Sylvius and his contemporaries in their practice of the new philosophy. This article finds that Sylvius's taste and his science both involved practices of social distinction, demarcation, and control. Moreover, both were enmeshed in controversy about the epistemological status of knowledge gained through the senses and about the practices by which that knowledge was gathered.

    2014-03-03

    Carriership of the factor V (FV) Leiden mutation increases the risk of venous thromboembolism (VTE) ~4-fold, but the individual risk of each FV Leiden carrier depends on several co-inherited risk and protective factors. Under the hypothesis that thrombin generation might serve as an intermediate phenotype to identify genetic modulators of VTE risk, we enrolled 188 FV Leiden heterozygotes (11 with VTE) and determined the following parameters: thrombin generation in the absence and presence of activated protein C (APC); plasma levels of prothrombin, factor X, antithrombin, protein S and tissue factor pathway inhibitor; and the genotypes of 24 SNPs located in the genes encoding these coagulation factors and inhibitors. Multiple regression analysis was subsequently applied to identify the (genetic) determinants of thrombin generation. The endogenous thrombin potential (ETP) showed a striking inter-individual variability among different FV Leiden carriers and, especially when measured in the presence of APC, correlated with VTE risk. Several SNPs in the F2 (rs1799963, rs3136516), F10 (rs693335), SERPINC1 (rs2227589), PROS1 (Heerlen polymorphism) and TFPI (rs5940) genes significantly affected the ETP-APC and/or the ETP+APC in FV Leiden carriers. Most of these SNPs have shown an association with VTE risk in conventional epidemiological studies, suggesting that the genetic dissection of thrombin generation leads to the detection of clinically relevant SNPs. In conclusion, we have identified several SNPs that modulate thrombin generation in FV Leiden heterozygotes. These SNPs may help explain the large variability in VTE risk observed among different FV Leiden carriers.

    AIM: To analyze the prevalence of the two commonest thrombophilic mutations, factor Ⅴ Leiden and prothrombin G20210A, in patients with gastric cancer.METHODS: One hundred and twenty-one patients with primary gastric carcinoma and 130 healthy subjects,comparable for age and sex, were investigated. Factor Ⅴ Leiden was detected by using polymerase chain reaction and restriction enzyme digestion, and prothrombin G20210A gene mutation by allele-specific PCR.RESULTS: Among the 121 cancer patients, factor Ⅴ Leiden was found in 4 cases (GA genotype: 3.3%) and prothrombin G20210A in 10 cases (GA genotype: 8.3%).Of the 130 control subjects, factor Ⅴ Leiden was detected in 6 cases (GA genotype: 4.6%) and prothrombin G20210A in 8 cases (GA genotype: 6.1%). No double heterozygous carriers of both mutations were found in either group. The prevalence of both factor Ⅴ Leiden and prothrombin G20210A variant was not statistically different between the cancer patients and the healthy subjects.CONCLUSION: Our study suggests that, in gastric cancer, the risk factors of thrombophilic cancer state are on acquired rather than on a genetic basis and that prothrombin G20210A does not seem to be a cofactor in gastric cancer pathogenesis.

    To report a patient case identifying risk for recurrent venous thromboembolism (VTE) associated with heterozygous Factor V Leiden mutation. A 54-year-old Caucasian male was diagnosed with heterozygous Factor V Leiden mutation in 2008 after experiencing a deep vein thrombosis (DVT) and bilateral pulmonary embolism. The patient was treated appropriately and started on anticoagulation therapy with warfarin through an anticoagulation management clinic. After approximately 17 months of warfarin therapy without incident, warfarin was discontinued. Within 2 months after discontinuation of anticoagulation therapy, the patient experienced his second DVT and left pulmonary artery embolus. The risk of recurrent venous thromboembolism (VTE) in patients with heterozygous Factor V Leiden mutation is documented as an approximate 1.4-fold increase compared to patients without thrombophilia. However, the risk increases dramatically when nonreversible (age) or reversible risk factors (obesity, smoking, and long air flights) are present in this population. Based on recent literature, heterozygous Factor V Leiden mutation exponentially increases the risk of recurrent VTE, especially in the presence of other risk factors. Health care providers should complete a comprehensive review of the patients' other risk factors when deciding on duration of anticoagulation therapy for patients with positive heterozygous Factor V Leiden mutation.

A total of 24 CVST patients with the mean age of 37.1 +/- 11.7 years and 100 sex- and age-matched healthy individuals from Kermanshah Province of Iran with ethnic background of Kurd were studied for factor V Leiden G1691A, prothrombin G20210A and MTHFR C677T by PCR-RFLP method using Mnl I, Hind III, and Hinf I restriction enzymes, respectively. Prevalence of factor V Leiden was 16.7% in patients and 2% in control group. A significant association was found between factor V Leiden mutation and CVST with odds ratio (OR) of 9.8 (95% confidence intervals [CI] 1.68-57.2, P = .01). No prothrombin G20210A was found among patients. In patients, MTHFR C677T tended to be higher (58.3%) compared to control (44%), OR of 1.8 (95% CI 0.73-4.5, P = .2). Our study for the first time has determined the prevalence of inherited thrombophilia in a homogenous ethnic group of CVST patients and suggests that factor V Leiden, and not the prothrombin gene mutation is a risk factor for CVST in Western Iran.

    Full Text Available Irregular immigration is a phenomenon with a substantial impact for the majority of the countries. The paper analyses whether there is an adequate human rights framework for protection of irregular immigrants or whether the irregular status exempts the migrants from the protection of international human rights law. If this is the case, then the human rights universality has failed. The paper takes into consideration the developments in the International and EU Law, as well as in the jurisprudence of the international tribunals regarding protection of irregular immigrants. It is divided into three main sections. The first section informs briefly on the dynamics of irregular immigrants; the second section analyses the legislation on irregular immigration from the perspective of the state sovereignty, the third section analyses the human rights law and the protection it affords to irregular immigrants, pursuant to the interpretation of International tribunals.

    Full Text Available Factor V Leiden mutation (Factor V Leiden is an autosomal dominant haemostatic disorder that predisposes affected persons to venous thromboembolic events (VTE. Although the mutation causing FVL is easily diagnosed using molecular DNA techniques, (1 patients who are heterozygous for this disorder often remain asymptomatic until they develop a concurrent prothrombotic condition. Pregnancy, which may increase an individual woman’s risk of venous thromboembolic events by 5- to 6-fold. (2 Because there are potentially serious effects of FVL for both the mother and the child, and availability of effective treatment strategies, early detection and treatment of this condition is warranted. (3 We are presenting this case in order to emphasise the existence of Factor V Leiden in Indian population and its approach during pregnancy.

    Ehlers-Danlos syndrome (EDS) is a group of inherited connective tissue disorders caused by collagen synthesis defects. Several hemostatic abnormalities have been described in EDS patients that increase the bleeding tendencies of these patients. This case report illustrates a patient with an unusual presentation of a patient with type IV EDS, platelet δ-storage pool disease and factor V Leiden mutation. Young woman having previous bilateral deep vein thrombosis and pulmonary emboli coexisting with ruptured splenic aneurysm and multiple other aneurysms now presented with myocardial infarction. Presence of factor V Leiden mutation raises the possibility that the infarct was due to acute coronary thrombosis, although coronary artery aneurysm and dissection with myocardial infarction is known to occur in vascular type EDS. This is the first report in the medical literature of factor V Leiden mutation in an EDS patient which made the management of our patient challenging with propensity to both bleeding and clotting.

    2014-04-01

    Our specific aim is to describe the development of thrombotic osteonecrosis of the jaws after testosterone-anastrozole therapy in a 55-year-old white man subsequently found to have previously undiagnosed factor V Leiden heterozygosity. Before the diagnosis of V Leiden heterozygosity, he was given testosterone gel, 50 mg/day, and on testosterone, serum testosterone (963 ng/dl) and estradiol were high (50 pg/ml). Anastrozole was started, and testosterone was continued. Six months later, osteonecrosis of the jaws was diagnosed. Exogenous testosterone is aromatized to estradiol and estradiol-induced thrombophilia, when superimposed on underlying familial thrombophilia, as in this case, may lead to thrombosis and osteonecrosis. We recommend that before giving testosterone, at a minimum, screening for the factor V Leiden and G20210A mutations, and factor VIII and XI activity be carried out, to avoid unanticipated thrombosis.

    The folding of the cortex in mammalian brains across species has recently been shown to follow a universal scaling law that can be derived from a simple physics model. However, it was yet to be determined whether this law also applies to the morphological diversity of different individuals in a single species, in particular with respect to factors, such as age, sex, and disease. To this end, we derived and investigated the cortical morphology from magnetic resonance images (MRIs) of over 1,000 healthy human subjects from three independent public databases. Our results show that all three MRI datasets follow the scaling law obtained from the comparative neuroanatomical data, which strengthens the case for the existence of a common mechanism for cortical folding. Additionally, for comparable age groups, both male and female brains scale in exactly the same way, despite systematic differences in size and folding. Furthermore, age introduces a systematic shift in the offset of the scaling law. In the model, this shift can be interpreted as changes in the mechanical forces acting on the cortex. We also applied this analysis to a dataset derived from comparable cohorts of Alzheimer's disease patients and healthy subjects of similar age. We show a systematically lower offset and a possible change in the exponent for Alzheimer's disease subjects compared with the control cohort. Finally, we discuss implications of the changes in offset and exponent in the data and relate it to existing literature. We, thus, provide a possible mechanistic link between previously independent observations.

    Role of genetic factors in etiology of preeclampsia is not confirmed yet. Gene defect frequency varies in different geographic areas as well as ethnic groups. In this study, the role of factor V Leiden mutation in the pathogenesis of preeclampsia syndrome among the pregnant population of northern shore of Persian Gulf in Iran, were considered. Between Jan. 2008 and Dec. 2009, in a nested case control study, pregnant women with preeclampsia (N=198) as cases and healthy (N=201) as controls were enrolled in the study. DNA were extracted from 10 CC peripheral blood and analyzed for presence of factor V Leiden mutation in these subjects. The maternal and neonatal outcomes of pregnancy according to the distribution of factor V Leiden were also compared among cases. In total, 17(8.6%) of cases and 2(1%) of controls showed the factor V Leiden mutation. The incidence of factor V Leiden was typically higher in preeclamptic women than control group (OR: 9.34 %95 CI: 2.12-41.01). There was no difference in incidence rate of preterm deliveryfactor V Leiden mutation. The pregnant women with factor V Leiden mutation are prone for preeclampsia syndrome during pregnancy, but this risk factor was not correlated to pregnancy complications in the studied women.

    To determine the association of factor V Leiden mutation with recurrent pregnancy loss. The case-control study was conducted at the Department of Haematology, Armed Forces Institute of Pathology, Rawalpindi, Pakistan, from January to June 2012, and comprised women of 18 to 45 years of age who had a history of recurrent pregnancy loss, and controls with no history of pregnancy loss. All the subjects belonged to Punjabi ethnic group. Three ml blood was taken from cases and controls and deoxyribonucleic acid was extracted. In order to identify Factor V Leiden mutation, polymerase chain reaction method was utilised combined with the amplification refractory mutation system. Data was analysed using SPSS 17. Of the 112 subjects, 56(50%) were in each of the two groups. The presence of factor V Leiden mutation among the cases was 3(5.4%) while it was absent among the controls. The mutation was significantly associated with recurrent pregnancy loss (p=0.017).Recurrent pregnancy loss was higher in cases than controls (p=0.001).

    Congenital hypofibrinogenemia and afibrinogenemia are usually associated with an increased risk of bleeding, but occurrence of arterial or venous thrombosis has also been reported in individuals with fibrinogen deficiency. This study reports on a 25-year-old patient with hypofibrinogenemia (fibrinogen 0.6 g/l) and congenital thrombophilia due to heterozygous factor V Leiden mutation who developed spontaneous deep-vein thrombosis (DVT) in the right lower extremity. Regardless of hypofibrinogenemia, he was receiving anticoagulant therapy over 6 months, with no occurrence of bleeding. His father is also a heterozygous carrier of factor V Leiden, but with normal fibrinogen level and he remained asymptomatic despite having experienced surgery in the past. This case, as well as data from literature, suggests that risk of thrombosis in carriers of factor V Leiden mutation is not counterbalanced by moderate congenital hypofibrinogenemia, and that antithrombotic prophylaxis should not be omitted in high-risk situations for occurrence of thrombosis in patients with coinheritance of hypofibrinogenemia and factor V Leiden mutation.

    Streptococcus pneumoniae infections continue to remain associated with high morbidity and mortality. Although the incidence of invasive meningeal and/or lung disease are not uncommon, Streptococcus pneumoniae endocarditis is rare especially in healthy pediatric population. New studies have suggested a strong association between factor V leiden (FVL) mutation and favorable outcomes in critically ill children. A healthy 10 month old presented with sepsis and meningeal signs, was later confirmed to have Streptococcus pneumoniae meningitis and endocarditis. She was found to have factor V leiden mutation and made a complete recovery despite initial complications. Presence of factor V leiden mutation in critically ill children with severe septicaemia possibly contributes to better outcomes. What is known: • Mortality and morbidity remain high with invasive pneumococcal disease. • Pneumococcal endocarditis is rare in healthy pediatric population and results in significant morbidity and mortality What is new: • New studies have suggested a strong association between factor V leiden (FVL) mutation and favorable outcomes in critically ill children. • The presence of factor V mutation in children with extensive invasive pneumococcal disease possibly contributes to a better outcome.

    The objective of this study is to systematically review methods for detecting Factor V Leiden or prothrombin G20210A. English-language literature from MEDLINE, EMBASE, The Cochrane Library, the Cumulative Index to Nursing and Allied Health Literature, PsycInfo(c), 2000-December 2008. Studies assessed methods for detection of these mutations in at least 10 human blood samples and reported concordance, discordance, or reproducibility. Two investigators abstracted data on the sample selection criteria, test operators, DNA extraction, experimental test, reference standard, commercial instruments, concordance rates, explanation of any discordance, and whether discordance resolved after repetition. We assessed strength of the evidence using the GRADE criteria. We reviewed 7,777 titles and included 66 articles. The majority of the reviewed studies used PCR-RFLP or AS-PCR as the reference standard. The studies demonstrated that commercially available and precommercial tests have high analytic validity with all having greater than 99% concordance with the reference standard. With a few exceptions, discordance resolved with repetition of the test, suggesting operator or administrative errors were responsible for the discordant results. In the quality assurance studies, greater than 98% of laboratories demonstrated high, even perfect, accuracy when asked to diagnose a sample with a known mutation. The majority of errors came from a limited number of laboratories. Although not all methods may be accurate, there is high-grade evidence that genetic tests for the detection of FVL and prothrombin G20210A have excellent analytic validity. There is high-grade evidence that most, but not all, clinical laboratories test for FVL and prothrombin G20210A accurately.

  7. Human Space Exploration and Human Space Flight: Latency and the Cognitive Scale of the Universe

    Science.gov (United States)

    Lester, Dan; Thronson, Harley

    2011-01-01

    The role of telerobotics in space exploration as placing human cognition on other worlds is limited almost entirely by the speed of light, and the consequent communications latency that results from large distances. This latency is the time delay between the human brain at one end, and the telerobotic effector and sensor at the other end. While telerobotics and virtual presence is a technology that is rapidly becoming more sophisticated, with strong commercial interest on the Earth, this time delay, along with the neurological timescale of a human being, quantitatively defines the cognitive horizon for any locale in space. That is, how distant can an operator be from a robot and not be significantly impacted by latency? We explore that cognitive timescale of the universe, and consider the implications for telerobotics, human space flight, and participation by larger numbers of people in space exploration. We conclude that, with advanced telepresence, sophisticated robots could be operated with high cognition throughout a lunar hemisphere by astronauts within a station at an Earth-Moon Ll or L2 venue. Likewise, complex telerobotic servicing of satellites in geosynchronous orbit can be carried out from suitable terrestrial stations.

  8. The Significance of UNESCO’s Universal Declaration on the Human Genome & Human Rights

    Full Text Available Modern medical research, particularly genetic research, is changing the nature of medicine. Concerns surrounding these changes and their potential negative impact on human rights led UNESCO to spearhead collaboration by experts in the creation of an international instrument intended to provide guidance for the promotion of bioethics and the protection of human rights in the genetic context. The result was the Universal Declaration of the Human Genome and Human Rights. This article briefly highlights the scientific and social setting into which the Declaration was injected. This is followed by a consideration of the drafting body (the IBC so as to assess whether UNESCO was the appropriate body to lead this project. The process by which the Declaration was created is also considered so as to assess whether it represents an example of ethical and democratic drafting. Finally, the substantive content of the Declaration is considered and measured against the pre-existing regime so as to assess whether it represents an intelligible and coherent response to the concerns raised capable of offering guidance now and into the future. By assessing these procedural and substantive matters, one can draw some tentative conclusions about the utility and significance of the Declaration.

    Both hereditary and acquired factors increase the risk of venous thromboembolism, thus the clinical management of affected patients involves evaluation of genetic factors that predispose to hypercoagulability. Factor V Leiden (R507Q) and factor II (prothrombin) mutation (G20210A) are the two most common inherited hypercoagulability disorders among populations of European origin. Both factor V Leiden and factor II mutation (G20210A) represent gain-of-function mutations: factor V Leiden causes resistance to activated protein C, and factor II mutation (G20210A) results in higher levels of plasma prothrombin. Herein, we present an uncommon case of combined factor V Leiden mutation (R507Q) and factor II mutation (G20210A), and discuss the prevalence and features of each entity, as well as their role in the clinical management of affected patients.

    Universe Awareness (UNAWE) is an educational programme coordinated by Leiden University that uses the beauty and grandeur of the Universe to encourage young children, particularly those from an underprivileged background, to have an interest in science and technology and foster their sense of global citizenship from the earliest age.UNAWE's twofold vision uses our Universe to inspire and motivate very young children: the excitement of the Universe provides an exciting introduction to science and technology, while the vastness and beauty of the Universe helps broaden the mind and stimulate a sense of global citizenship and tolerance. UNAWE's goals are accomplished through four main activities: the coordination of a global network of more than 1000 astronomers, teachers and educators from more than 60 countries, development of educational resources, teacher training activities and evaluation of educational activities.Between 2011 and 2013, EU-UNAWE, the European branch of UNAWE, was funded by the European Commission to implement a project in 5 EU countries and South Africa. This project has been concluded successfully. Since then, the global project Universe Awareness has continued to grow with an expanding international network, new educational resources and teacher trainings and a planned International Workshop in collaboration with ESA in October 2015, among other activities.

    Full Text Available Sneddon syndrome (SNS, characterized by livedo racemosa and stroke, is a rare disease, especially in young adults. Livedo racemosa are large lesions, widespread on the extremities and the body, that are violet-colored and have a good appearance and ambiguous limits. A 33-years-old female presented to our clinic for headache. She had a two-year history of blue-purple skin marks on her body and legs. The skin lesions were consistent with livedo racemosa. She had experienced right hemiparesis according to her medical history. Factor V Leiden (G1691A mutation was heterozygote-positive. Methylenetetrahydrofolate reductase (MTHFR C677T and FMF gene (MEFV V726A mutations were determined. SNS is the cause of stroke, rarely seen in young adults. We considered this case to be of value since it is the first SNS case having factor V Leiden, MTHFR and MEFV mutations concomitantly.

    2016-01-01

    Full Text Available Essential thrombocytosis (ET and FV Leiden heterozygosity represent an acquired and hereditable hypercoagulable state, respectively. An uncommon case of coexistence of ET and FV Leiden heterozygosity in a 36-year-old pregnant woman and her successful pregnancy outcome is described. She was considered to be at high risk of thrombosis during her pregnancy and she was treated with both prophylactic dose of LMWH and aspirin daily throughout her pregnancy and for a 6-week period postpartum. The efficacy of the anticoagulation treatment was monitored in various time points not only by measuring anti-Xa levels and D-Dimers but also with new coagulation methods such as rotation thromboelastometry and multiplate. Global assessment of coagulation using additional newer laboratory tests might prove useful in monitoring coagulation pregnancies at high risk for thrombosis.

  2. Paternal factor V Leiden and recurrent pregnancy loss: a new concept behind fetal genetics?

    2014-05-01

    In up to 50% of couples affected by recurrent pregnancy loss, no identifiable cause is established. Fetal and maternal factors may be equally important in the establishment and maintenance of the placental/maternal arteriovenous anastomoses. Therefore,the inheritance of thrombophilia-related genes may be an important factor in the pathophysiology of recurrent pregnancy loss. Most of the research on recurrent pregnancy loss and thrombophilia has focused on maternal factors, but little is known about the paternal contribution. On that basis, we studied the association between inherited paternal thrombophilias and recurrent pregnancy loss in a narrowly selective group of 42 Argentine males from couples that presented without any known risk factors for recurrent pregnancy loss. The genotypic distributions of factor (F) V Leiden and prothrombin G20210A among cases were compared with those from a reference group composed of 200 Argentine men. We found a significant difference in the distribution of FV Leiden between both groups (16.7% vs. 3.0%), but no difference was found in the distribution of prothrombin G20210A (2.4% vs.2.0%). Those couples with paternal FV Leiden carriage would be six times more likely to experience recurrent pregnancy loss despite no other apparent cause (OR = 6.47; 95% CI, 2.06–20.39). We found evidence of an association between the paternal carriage of FV Leiden and the predisposition to recurrent pregnancy loss, thereby supporting the hypothesis that genetic contributions from both parents are essential factors in the development of this obstetric disorder.

  3. Meta-analysis of factor V Leiden and prothrombin G20210A polymorphism in migraine.

    Migraine is a frequent and disabling condition, which exhibits a substantial genetic background and is frequently associated with abnormalities of primary and secondary hemostasis. We performed a systematic literature search and a meta-analysis of available data about the potential associations between migraine and factor V (FV) Leiden or prothrombin (FII) G20210A gene polymorphism. The final number of studies included was 15 (all cross-sectional) about migraine and FV Leiden, and 12 (all cross-sectional) about migraine and FII G20210A polymorphism, with broad inter-study heterogeneity (I², 82 and 85%). The cumulative prevalence of the FV 1691A allele was found to be similar between cases (n = 1450; 4.9%) and controls (n = 3468; 4.7%; P = 0.74). The cumulative prevalence of the FII 20210A allele was also found to be similar between cases (n = 1226; 4.2%) and controls (n = 3144; 4.5%; P = 0.59). Nevertheless, sub-analysis of studies in adults and children revealed that both polymorphisms were not associated with migraine in adults, but FV Leiden and the FII 20210A allele were approximately two-fold more prevalent in children with migraine than in those without. In conclusion, despite migraine exhibits a clear neurovascular origin and is frequently associated with thrombotic disorders, isolate thrombophilic mutations seem to play a negligible pathogenetic role in this condition in adults, whereas the increased prevalence of FV Leiden and the FII 20210A allele in children with migraine deserves further scrutiny.

    The human factor is central to healthcare, yet its proper management has remained beyond the reach of healthcare organizations. This qualitative study examines strategic human resource management (HRM) issues in a university and a community hospital. The findings indicate that the two hospitals lacked a clear understanding of their strategic intent and objectives; as a result, their human resource (HR) practices lacked coherence and direction. Whereas the community hospital understood the interrelationship between culture and HRM, the university hospital did not. Moreover, the university hospital showed only a modest understanding of competencies needed in managing HR function, which hampered its ability to identify competent HR managers and employees. The community hospital made significant gains in the past few years in managing its culture and people by recruiting a competent HR manager. The relationship between HR practices and clinical outcomes was much less clear in the university hospital than it was in the community hospital.

This case describes a 58-year-old woman with factor V Leiden mutation who required distal saphenous vein harvest and axillo-brachial bypass to treat axillary artery occlusion. The patient underwent surgery with satisfactory anesthesia using infraclavicular brachial plexus block, thoracic paravertebral block, and unilateral subarachnoid block. These three regional anesthetic interventions were performed in lieu of general anesthesia to minimize risks of thrombotic events, pain, and to decrease recovery time. Despite higher failure rates of regional anesthesia, longer time required for procedures, and added discomforts during surgery, the benefits may outweigh risks for selected high-risk patients, including those with factor V Leiden mutations.Keywords: regional anesthesia, factor V Leiden, pain, vein harvest

    Factor V Leiden deficiency is the most common hereditary hypercoagulable disease in the United States and involves 5% of the Caucasian population. Up to 30% of patients who present with deep vein thrombosis (DVT) or pulmonary thromboembolism present with this condition. This is a case report of a 36-year-old man who experienced one episode of DVT within the previous year and was admitted to our hospital due to productive coughs and hemoptysis. Paraclinical studies demonstrated a right ventricular thrombus. Additional investigation was done to find the underlying cause. Laboratory tests were positive for Factor V Leiden mutation. Other factors for hypercoagulability states were normal. Given that Factor V Leiden mutation is a life-threatening condition with a relatively high prevalence and considering its thrombogenesis, screening tests are necessary in young patients without obvious reasons for recurrent thrombus formation. It seems that medical noninvasive treatments can be an alternative therapy to surgery when a ventricular thrombus is suspected in these patients.

    Full Text Available Background: Role of genetic factors in etiology of preeclampsia is not confirmed yet.Objective: Gene defect frequency varies in different geographic areas as well as ethnic groups. In this study, the role of factor V Leiden mutation in the pathogenesis of preeclampsia syndrome among the pregnant population of northern shore of Persian Gulf in Iran, were considered.Materials and Methods: Between Jan. 2008 and Dec. 2009, in a nested case control study, pregnant women with preeclampsia (N=198 as cases and healthy (N=201 as controls were enrolled in the study. DNA were extracted from 10 CC peripheral blood and analyzed for presence of factor V Leiden mutation in these subjects. The maternal and neonatal outcomes of pregnancy according to the distribution of factor V Leiden were also compared among cases.Results: In total, 17(8.6% of cases and 2(1% of controls showed the factor V Leiden mutation. The incidence of factor V Leiden was typically higher in preeclamptic women than control group (OR: 9.34 %95 CI: 2.12-41.01. There was no difference in incidence rate of preterm delivery< 37 weeks (OR: 1.23 %95 CI: 0.38-4.02, very early preterm delivery<32 weeks (OR: 1.00 %95 CI: 0.12-8.46, intra uterine fetal growth restriction (IUGR (OR: 1.32 %95 CI: 0.15-11.30 ,and the rate of cesarean section (OR: 0.88 %95 CI: 0.29-2.62 among cases based on the prevalence of factor V Leiden mutation.Conclusion: The pregnant women with factor V Leiden mutation are prone for preeclampsia syndrome during pregnancy, but this risk factor was not correlated to pregnancy complications in the studied women

  13. Reconciling Universality and Particularity through a Cosmopolitan Outlook on Human Rights

    2012-08-01

    Full Text Available Human rights are today criticized as not compatible with different cultural values and the debate has circulated around Asian values and Islamic values as in dichotomy with human rights as universal ethics (Ignatieff, 2003. The theoretical dichotomy between universality and particularity is questioned pragmatically in this paper through a historical study. The working process of drafting the Universal Declaration of Human Rights (UDHR in 1946-48, which included thousands of people, is explored as a cosmopolitan space in which individuals from different cultural contexts met to negotiate human rights through cultural narratives. The process where particular values were negotiated with universal notion on human rights resulted in a common proclamation (UDHR without a common philosophical or ideological ground. This paper puts forth a thesis that human rights discourse can work as a cosmopolitan space, in which particular value systems meet in processes characterized by conflict and cohesion. Hence human rights can be understood as a master narrative compatible with different conflicting cultural narratives (Gibson & Somers, 1994.

  14. Both transient and continuous corticosterone excess inhibit atherosclerotic plaque formation in APOE*3-leiden.CETP mice.

    Directory of Open Access Journals (Sweden)

    Hanna E Auvinen

    Full Text Available INTRODUCTION: The role of glucocorticoids in atherosclerosis development is not clearly established. Human studies show a clear association between glucocorticoid excess and cardiovascular disease, whereas most animal models indicate an inhibitory effect of glucocorticoids on atherosclerosis development. These animal models, however, neither reflect long-term glucocorticoid overexposure nor display human-like lipoprotein metabolism. AIM: To investigate the effects of transient and continuous glucocorticoid excess on atherosclerosis development in a mouse model with human-like lipoprotein metabolism upon feeding a Western-type diet. METHODS: Pair-housed female APOE*3-Leiden.CETP (E3L.CETP mice fed a Western-type containing 0.1% cholesterol for 20 weeks were given corticosterone (50 µg/ml for either 5 (transient group or 17 weeks (continuous group, or vehicle (control group in the drinking water. At the end of the study, atherosclerosis severity, lesion area in the aortic root, the number of monocytes adhering to the endothelial wall and macrophage content of the plaque were measured. RESULTS: Corticosterone treatment increased body weight and food intake for the duration of the treatment and increased gonadal and subcutaneous white adipose tissue weight in transient group by +35% and +31%, and in the continuous group by +140% and 110%. Strikingly, both transient and continuous corticosterone treatment decreased total atherosclerotic lesion area by -39% without lowering plasma cholesterol levels. In addition, there was a decrease of -56% in macrophage content of the plaque with continuous corticosterone treatment, and a similar trend was present with the transient treatment. CONCLUSION: Increased corticosterone exposure in mice with human-like lipoprotein metabolism has beneficial, long-lasting effects on atherosclerosis, but negatively affects body fat distribution by promoting fat accumulation in the long-term. This indicates that the increased

    Low-grade inflammation in different tissues, including activation of the nuclear factor κB pathway in liver, is involved in metabolic disorders such as type 2 diabetes and cardiovascular diseases (CVDs). In this study, we investigated the relation between chronic hepatocyte-specific overexpression of IkB kinase (IKK)-β and hypertriglyceridemia, an important risk factor for CVD, by evaluating whether activation of IKK-β only in the hepatocyte affects VLDL-triglyceride (TG) metabolism directly. Transgenic overexpression of constitutively active human IKK-β specifically in hepatocytes of hyperlipidemic APOE*3-Leiden mice clearly induced hypertriglyceridemia. Mechanistic in vivo studies revealed that the hypertriglyceridemia was caused by increased hepatic VLDL-TG production rather than a change in plasma VLDL-TG clearance. Studies in primary hepatocytes showed that IKK-β overexpression also enhances TG secretion in vitro, indicating a direct relation between IKK-β activation and TG production within the hepatocyte. Hepatic lipid analysis and hepatic gene expression analysis of pathways involved in lipid metabolism suggested that hepatocyte-specific IKK-β overexpression increases VLDL production not by increased steatosis or decreased FA oxidation, but most likely by carbohydrate-responsive element binding protein-mediated upregulation of Fas expression. These findings implicate that specific activation of inflammatory pathways exclusively within hepatocytes induces hypertriglyceridemia. Furthermore, we identify the hepatocytic IKK-β pathway as a possible target to treat hypertriglyceridemia.

    In 2010, Vermont adopted a new law embracing human rights principles as guidelines for health care reform, and in 2011, Vermont was the first state in the US to enact framework legislation to establish a universal health care system for all its residents. This article reports on the Vermont Workers' Center's human rights-based approach to universal health care and the extent to which this approach influenced decision makers. We found the following: (1) by learning about the human right to health care and sharing experiences, Vermonters were motivated to demand universal health care; (2) mobilizing Vermonters around a unified message on the right to health care made universal health care politically important; (3) using the human rights framework to assess new proposals enabled the Vermont Workers' Center to respond quickly to new policy proposals; (4) framing health care as a human right provided an alternative to the dominant economics-based discourse; and (5) while economics continues to dominate discussions among Vermont leaders, both legislative committees on health care use the human rights principles as guiding norms for health care reform. Importantly, the principles have empowered Vermonters by giving them more voice in policymaking and have been internalized by legislators as democratic principles of governance.

  17. Human rights on the thin red line between universality and relativity

    2014-01-01

    Full Text Available Human rights represent an open legal and political concept with a very wide value variable. Academic discussions on human rights nature have mostly commenced after the World War II during the trend of human rights internationalization, reaching their climax after the Cold war. This paper examines actual theories on human rights, from those accepting them as universal, up to those marking another pole, favoring idea of absolute relativity of human rights. The author asserts that the most acceptable should be a middle solution, standing of moderate relativism or position of relative universalism of human rights. He claims that only a very limited circle of basic, 'substantial' human rights, having been accepted through an intercultural consensus, may pretend to be treated as universal. Out of that narrow sphere, there are many other human rights whose meaning and interpretation depend strongly upon concrete cultural context. The author points that in those cases it is important to respect a relativistic discourse and that the only solution should be explored within an intercultural and inter-civilizational dialogue, where non-western values should be equally treated as the western ones.

    AIM: To analyze the serum levels of retinoids and Leiden mutation in patients with esophageal, gastric, liver,pancreatic, and colorectal cancers.METHODS: The changes in serum levels of retinoids (vitamin A, α- and β-carotene, α- and β-cryptoxanthin,zeaxanthin, lutein) and Leiden mutation were measured by high liquid performance chromatography (HPLC)and polymerase chain reaction (PCR) in 107 patients (70 males/37 females) with esophageal (0/8), gastric (16/5), liver (8/7), pancreatic (6/4), and colorectal (30/21including 9 patients suffering from in situ colon cancer)cancer. Fifty-seven healthy subjects (in matched groups)for controls of serum retinoids and 600 healthy blood donors for Leiden mutation were used.RESULTS: The serum levels of vitamin A and zeaxanthin were decreased significantly in all groups of patients with gastrointestinal (GI) tumors except for vitamin A in patients with pancreatic cancer. No changes were obtained in the serum levels of α- and β-carotene,α- and β-cryptoxanthin, zeaxanthin, lutein in patients with GI cancer. The prevalence of Leiden mutation significantly increased in all groups of patients with GI cancer.CONCLUSION: Retinoids (as environmental factors)are decreased significantly with increased prevalence of Leiden mutation (as a genetic factor) in patients before the clinical manifestation of histologically different (planocellular and hepatocellular carcinoma, and adenocarcinoma) GI cancer.

    Full Text Available The demand for higher education in Nigeria has been considered as not only an investment in human capital, but also a pre-requisite for economic development. Consequent upon the expansion of higher education in Nigeria, quite a number of institutions have suffered decay due to poor work environments, inadequate educational facilities and poor funding which have resulted into unabated brain drain, strike and turnover. However, the need to develop talents is no longer hidden, what remains controversial is knowing the best method for managing human capacity especially in Nigerian State owned universities. Thus, this study examined the relationship between human capital management and organizational success using three State owned universities in Southwest, Nigeria. These universities (Ekiti State University (EKSU, Lagos State University (LASU, Tai Solarin University of Education (TASUED were chosen for their uniqueness. Survey research design was adopted with 398 respondents (staff. Self-administered questionnaire was adopted and analyzed with the adoption of Structural Equation Modelling (SEM. However, the results indicated that adequate leadership practices; learning capacity; workforce optimization; knowledge accessibility; workplace culture and; mentorship are significant predictors of organizational success in higher education.

  1. Global bioethics: did the universal declaration on bioethics and human rights miss the boat?

    Macpherson, Cheryl Cox

    2007-10-01

    This paper explores the evolution of the Universal Declaration on Bioethics and Human Rights (UDBHR), which was adopted by the United Nations Educational, Scientific and Cultural Organization (Unesco) in 2005. While the draft UDBHR generated controversy among bioethicists, the process through which it evolved excluded mainstream bioethicists. The absence of peer review affects the declaration's content and significance. This paper critically analyses its content, commenting on the failure to acknowledge socioeconomic and other factors that impede its implementation. The UDBHR outlines ideal standards but fails to provide guidance that can be readily applied in different settings. It strives for universality but does not contribute to understanding of universal or global bioethics.

    The current Medical Humanities Program at the University of Manitoba has evolved from a series of voluntary sessions into an integral element of the curriculum since its inception as the Human Values Program in 1986. With strong academic and financial support, the Medical Humanities Program has greatly benefited from dedicated leadership and a commitment to ongoing curricular review and redevelopment. The current Medical Humanities Program comprises six distinct components: Clinical Ethics; History of Medicine; Law; Complementary and Alternative Medicine; Palliative Care; and Human Values. Each of these components is compulsory and the first five are tested through examinations and assignments. Human Values sessions are designed to be experiential and to explore the human side of medicine as well as the intersections between medicine and the arts, literature, social psychology, and spirituality. The authors outline the origins and evolution of this successful program and describe its current components, student and faculty opinions, funding, advantages, disadvantages, and anticipated growth.

    The clinical characteristics of patients with factor V Leiden or prothrombin G20210A presenting with a first episode of venous thromboembolism (VTE) have not been thoroughly studied. RIETE is an ongoing registry of consecutive patients with acute VTE. We compared the clinical characteristics of patients with factor V Leiden, prothrombin G20210A, or no thrombophilia, at presentation with a first episode of VTE. As of May 2009, 22428 patients had been enrolled with a first episode of VTE. Of these, 345 had factor V Leiden, 261 had prothrombin G20210A, and 2399 tested negative. Sixty-two percent of the VTE episodes in women with factor V Leiden or prothrombin G20210A (40% in men) were associated with an acquired risk factor. Among women, pregnancy or contraceptive use accounted for 63% and 67% of such risk factors. Patients with factor V Leiden presented with pulmonary embolism (PE) less likely than those with prothrombin G20210A (31% vs. 51%; pFactor V Leiden presented with hypoxaemia (Sat O(2) levelsfactor V Leiden or prothrombin G20210A were associated with an acquired risk factor (mostly pregnancy or contraceptive use).

    This study examined a possible association between the mutations related to Factor V Leiden and Factor II (prothrombin) and stroke in Saudi neonates. A multiplex PCR was established to detect Factor V Leiden G1691A and prothrombin G20210A mutations in 72 neonatal stroke subjects and 70 healthy adult controls with no family history of thromboembolic diseases. The frequency of the homozygous normal genotype (GG) of both genes was found to be significantly lower in the stroke subjects than in the controls (P Factor II heterozygous mutant form (GA) and the homozygous normal Factor V (GG) (P Factor V and the homozygous normal Factor II genotypes (GG) (P = 0.0) than controls. The study concluded that prothrombin and Factor V Leiden may be important risk factors for neonatal stroke in Saudi children.

    Because the venous thromboembolisms (VTEs) due to the coagulation factor V R506Q (FV Leiden) mutation is often seen in Caucasians, the VTE onset in Japan has not been reported. A 34-year-old man from north Africa experiencing sudden dyspnea went to a hospital for advice. The patient had pain in his right leg and a high plasma D-dimer level. A contrast-enhanced computed tomography scan revealed a contrast deficit in the bilateral pulmonary artery and in the right lower extremity. The patient was diagnosed with VTE, and anticoagulation therapy was initiated. Our targeted gene panel sequencing revealed that the occurrence of VTE was attributed to a presence of the FV Leiden mutation. This is the first report demonstrating VTE caused by the FV Leiden mutation in Japan.

  9. Human rights from the grassroots up: Vermont's campaign for universal health care.

    2012-06-15

    In 2008, the Vermont Workers' Center launched the "Healthcare Is a Human Right Campaign," a grassroots campaign to secure the creation of a universal health care system in Vermont. Campaign organizers used a human rights framework to mobilize thousands of voters in support of universal health care. In response to this extraordinary grassroots effort, the state legislature passed health care legislation that incorporates human rights principles into Vermont law and provides a framework for universal health care. The United States has often lagged behind other nations in recognizing economic, social, and cultural (ESC) rights, including the right to health. Nonetheless, activists have begun to incorporate ESC rights into domestic advocacy campaigns, and state and local governments are beginning to respond where the federal government has not. Vermont serves as a powerful example of how a human rights framework can inform health care policy and inspire grassroots campaigns in the United States. This three-part article documents the Vermont Workers' Center campaign and discusses the impact that human rights activity at the grassroots level may have on attitudes towards ESC rights in the United States. The first part describes the Vermont health care crisis and explains why the center adopted international human rights principles for their campaign. The article then goes on to discuss the three-year campaign and analyze the health care reform bill that the Vermont legislature passed. Finally, the article discusses the campaign's local and national impact. Copyright © 2012 McGill.

    Individuals with factor V Leiden or prothrombin G20210A mutations are at a higher risk to develop venous thromboembolism. However, the influence of these polymorphisms on patient outcome during anticoagulant therapy has not been consistently explored. We used the Registro Informatizado de Enfermedad TromboEmbólica database to compare rates of venous thromboembolism recurrence and bleeding events occurring during the anticoagulation course in factor V Leiden carriers, prothrombin mutation carriers, and noncarriers. Between March 2001 and December 2015, 10,139 patients underwent thrombophilia testing. Of these, 1384 were factor V Leiden carriers, 1115 were prothrombin mutation carriers, and 7640 were noncarriers. During the anticoagulation course, 160 patients developed recurrent deep vein thrombosis and 94 patients developed pulmonary embolism (16 died); 154 patients had major bleeding (10 died), and 291 patients had nonmajor bleeding. On multivariable analysis, factor V Leiden carriers had a similar rate of venous thromboembolism recurrence (adjusted hazard ratio [HR], 1.16; 95% confidence interval [CI], 0.82-1.64), half the rate of major bleeding (adjusted HR, 0.50; 95% CI, 0.25-0.99) and a nonsignificantly lower rate of nonmajor bleeding (adjusted HR, 0.66; 95% CI, 0.43-1.01) than noncarriers. Prothrombin mutation carriers and noncarriers had a comparable rate of venous thromboembolism recurrence (adjusted HR, 1.00; 95% CI, 0.68-1.48), major bleeding (adjusted HR, 0.75; 95% CI, 0.42-1.34), and nonmajor bleeding events (adjusted HR, 1.10; 95% CI, 0.77-1.57). During the anticoagulation course, factor V Leiden carriers had a similar risk for venous thromboembolism recurrence and half the risk for major bleeding compared with noncarriers. This finding may contribute to decision-making regarding anticoagulation duration in selected factor V Leiden carriers with venous thromboembolism. Copyright © 2017. Published by Elsevier Inc.

    The value of genetic thrombophilia testing in elderly patients with an unprovoked venous thromboembolism is unclear. We assessed whether the Factor V Leiden and the prothrombin G20210A mutation are associated with recurrent venous thromboembolism in elderly patients in a prospective multicenter cohort study. We genotyped the Factor V Leiden and the prothrombin G20210A mutation in 354 consecutive in- and outpatients aged ≥65 years with a first unprovoked venous thromboembolism from 9 Swiss hospitals. Patients and managing physicians were blinded to testing results. The outcome was recurrent symptomatic venous thromboembolism during follow-up. We examined the association between the Factor V Leiden and the prothrombin G20210A mutation and venous thromboembolism recurrence using competing risk regression, adjusting for age, sex, and periods of anticoagulation as a time-varying covariate. Overall, 9.0% of patients had a Factor V Leiden and 3.7% had a prothrombin G20210A mutation. At 36 months of follow-up, patients with a Factor V Leiden and a prothrombin G20210A mutation had a cumulative incidence of recurrent venous thromboembolism of 12.9% (95% confidence interval [CI], 5.1%-30.8%) and 18.5% (95% CI, 4.9%-56.5%), respectively, compared with 16.7% (95% CI, 12.5%-22.1%) of patients without mutation (P = .91 by the log-rank test). After adjustment, neither the Factor V Leiden (sub-hazard ratio 0.98; 95% CI, 0.35-2.77) nor the prothrombin G20210A mutation (sub-hazard ratio 1.15; 95% CI, 0.25-5.19) was associated with recurrent venous thromboembolism. Our results suggest that testing for genetic thrombophilia may not be beneficial in elderly patients with a first unprovoked venous thromboembolism. Copyright © 2017 Elsevier Inc.

  14. Whose dignity? Resolving ambiguities in the scope of "human dignity" in the Universal Declaration on Bioethics and Human Rights.

    Science.gov (United States)

    Schmidt, Harald

    2007-10-01

    In October 2005, the United Nations Educational, Scientific and Cultural Organization adopted the Universal Declaration on Bioethics and Human Rights (UDBHR). A concept of central importance in the declaration is that of "human dignity". However, there is lack of clarity about its scope, especially concerning the question of whether prenatal human life has the same dignity and rights as born human beings. This ambiguity has implications for the interpretation of important articles of the delcaration, including 2(c), 4, 8, 10 and 11. The paper applies relevant provisions of the UDBHR to specific cases, addresses problems of internal consistency and considers attempts at clarifying the scope of "human dignity" by the negotiating parties. An analysis of the important relationship between the UDBHR and the Universal Declaration of Human Rights, to which the UDBHR refers in its title and elsewhere, shows that because of a crucial emphatic asymmetry, a broad reading according to which the UDBHR must be understood to ascribe human rights and dignity to prenatal life is untenable. However, the view that the UDBHR confers human rights and dignity on humans from the moment of birth onwards is robust and defensible. This conclusion is important for a proper understanding of the declaration and its use, as stated in Articles 1(2) and 22, the latter urging states ".. to give effect to the principles .. in this declaration". Similarly, it has implications for the use of the declaration in the wider context of bioethics-related law and policy, as well as in academic and other discussions where increasing reference to the UDBHR is likely.

    Activated protein C (APC) resistance, often associated with the factor V (FV) Leiden mutation, is the most common risk factor for venous thrombosis. We observed increased APC resistance in carriers of fibrinogen γ gene (FGG) haplotype 2, which is associated with reduced levels of the alternatively spliced fibrinogen γ' chain. This finding prompted us to study the effects of fibrinogen and its γ' chain on APC resistance. Fibrinogen, and particularly the γA/γ' isoform, improved the response of plasma to added APC in the thrombin generation-based assay. Similarly, a synthetic peptide mimicking the C-terminus of the fibrinogen γ' chain, which binds thrombin and inhibits its activities, greatly increased the APC sensitivity of normal and FV Leiden plasma, likely due to its ability to inhibit thrombin-mediated activation of FV and FVIII. Although the fibrinogen γ' peptide also inhibited protein C activation by the thrombin/thrombomodulin complex, it still increased the sensitivity of plasma to endogenously formed APC when thrombin generation was measured in the presence of soluble thrombomodulin. We conclude that fibrinogen, and particularly fibrinogen γ', increases plasma APC sensitivity. The fibrinogen γ' peptide might form the basis for pharmacologic interventions to counteract APC resistance. © 2014 by The American Society of Hematology.

    Full Text Available Normal hemostasis requires balanced regulation of prothromboticand antithrombotic factors. Inherited alteration of factor Vand prothrombin gene, the G20210A mutation, increases the resistanceof factor V to degradation and booster production ofprothrombin respectively. These alterations can increase hypercoagulabilityleading to thrombotic consequences. We aimed toassess the frequencies of these mutations in a group of the populationof southern Iran. In total, 198 healthy volunteers with theage range of 1-64 years were selected and screened for factor VLeiden and prothrombin mutations using polymerase chain reactionand restriction fragment length polymorphism techniques.The carrier frequencies for factor V Leiden and prothrombin mutationin the studied cohort were 4.1% and 3.07%, respectively.In the studied area, the allele frequency of factor V ishigher than the prothrombin G20210A mutation (0.0204 v0.0153. According to the data and Hardy-Weinberger equation,the total risk of thrombosis caused by homozygosity andheterozygosity of factor V Leiden, prothrombin G20210A mutationand compound heterozygosity of these mutations areabout 1 in 500 individuals.

    Multiple brain abscesses in an immunocompetent patient is a challenging clinical problem in the medical world despite advances in imaging techniques, laboratory diagnostics, surgical interventions, and antimicrobial treatment. It is a clinical entity that typically tends to occur in the presence of known predisposing factors. Clinicians seek to determine the potential risk factors responsible for the development of brain abscess because it is very crucial for management of this life-threatening condition. At times, like in our case, there are clinical situations where it is difficult to reveal any traditional risk factors. We report a case of multiple brain abscesses in a 51-year-old female with a past medical history significant only for factor V Leiden mutation, and deep vein thrombosis on chronic anticoagulation. She underwent thorough evaluation but no predisposing factors were found. Based on our extensive literature review, this is the index case of multiple brain abscesses in a patient with history of factor V Leiden mutation and the absence of any conventional risk factors. We also postulate a possible mechanism of infection in such patients.

    Venous thromboembolism is a serious, potentially lethal health problem affecting one per 1,000 people annually. Major surgery, the use of oral contraceptives, complicated pregnancy, fractures, and immobilization increase the risk of thrombosis. In addition to these factors, thrombosis is associated with inherited deficiencies of antithrombin III, protein C, and protein S. Together these do not account for more than five to 10% of the cases. Hereditary activated protein C resistance has been recognized as a basis for a majority of cases of familial thrombosis. It accounted for more than a 10 times higher number than that of other known genetic defects. We describe a case of a young female who presented with a pulmonary embolism and was discovered to have activated protein C resistance. This patient had a heterozygous mutation for factor V Leiden and was taking oral contraceptives. This report underlines: 1) increased risk of venous thrombosis in oral contraceptive users who carry factor V Leiden mutation associated with functional resistance to the normal anticoagulation activities of protein C; 2) most episodes occurring in the young are minor, but pulmonary embolus can occur; 3) the importance of identifying other affected members of the family; and 4) the importance of anticoagulation prophylaxis at times of enhanced risk, particularly during pregnancy, postpartum, and major surgery.

    Human movements in the real world and in cyberspace affect not only dynamical processes such as epidemic spreading and information diffusion but also social and economical activities such as urban planning and personalized recommendation in online shopping. Despite recent efforts in characterizing and modeling human behaviors in both the real and cyber worlds, the fundamental dynamics underlying human mobility have not been well understood. We develop a minimal, memory-based random walk model in limited space for reproducing, with a single parameter, the key statistical behaviors characterizing human movements in both spaces. The model is validated using big data from mobile phone and online commerce, suggesting memory-based random walk dynamics as the universal underpinning for human mobility, regardless of whether it occurs in the real world or in cyberspace.

    McFarland, Sam

    2010-12-01

    All individual differences that predict support for international human rights are first reviewed: support for human rights is linked most positively to "globalism" (other international and environmental concerns), "identification with all humanity," principled moral reasoning, benevolence, and dispositional empathy. It is related most negatively to ethnocentrism and its root dispositions, the social dominance orientation, and authoritarianism. Other correlates are also noted. Secondly, a structural model of the effects of authoritarianism, social dominance, ethnocentrism and identification with all humanity upon commitment to human rights is presented and tested. Across 2 studies (Study 1, N=218 nonstudent adults; Study 2, N=102 university students), ethnocentrism and identification with all humanity directly predicted human rights commitment. The effects of authoritarianism upon this commitment were fully mediated through enhanced ethnocentrism and reduced identification with all humanity. The effects of social dominance were similar, but its direct effect upon human rights commitment remained significant and was not, in the second study, mediated by reduced dispositional empathy. © 2010 The Author.

    Full Text Available Objective: Budd-Chiari syndrome is a multifactorial disease in which several prothrombotic disorders may predispose patients to the development of thrombosis at this uncommon location (hepatic veins. The aim of this study was to determine the prevalence and characteristics of inherited thrombophilia in Egyptian Budd-Chiari syndrome patients.Materials and Methods: The study included 47 Budd-Chiari syndrome patients (20 children and 27 adults. Genotyping of Factor V G1691A (Leiden, prothrombin G20210A (PT, and methylenetetrahydrofolate reductase C677T were performed using real-time PCR and fluorescence melting curve detection analysis.Results: Factor V Leiden was observed in 29 patients (61.7%. It is the only factor that caused Budd-Chiari syndrome in 18 of the patients and in 5 of the patients with inferior vena cava involvement. Myeloproliferative disease was noted in 12 (25.5% patients, antiphospholipid syndrome in 5 (10.6%, and Behcet’s disease in 3 (6.4%. Interestingly, 3 of the children with Budd-Chiari syndrome had lipid storage disease.Conclusion: Factor V Leiden was a major etiological factor in Egyptian Budd-Chiari syndrome patients, which may have been related to the high frequency of this mutation in the study region. Factor V Leiden was also a strong thrombophilic factor and the leading cause of inferior vena cava thrombosis in these patients. Lipid storage disease should be included as a risk factor for Budd-Chiari syndrome.

    The peroxisome proliferator-activated receptor alpha (PPARalpha) activator fenofibrate efficiently decreases plasma triglycerides (TG), which is generally attributed to enhanced very low density lipoprotein (VLDL)-TG clearance and decreased VLDL-TG production. However, because data on the effect of fenofibrate on VLDL production are controversial, we aimed to investigate in (more) detail the mechanism underlying the TG-lowering effect by studying VLDL-TG production and clearance using APOE*3-Leiden.CETP mice, a unique mouse model for human-like lipoprotein metabolism. Male mice were fed a Western-type diet for 4 weeks, followed by the same diet without or with fenofibrate (30 mg/kg bodyweight/day) for 4 weeks. Fenofibrate strongly lowered plasma cholesterol (-38%) and TG (-60%) caused by reduction of VLDL. Fenofibrate markedly accelerated VLDL-TG clearance, as judged from a reduced plasma half-life of glycerol tri[(3)H]oleate-labeled VLDL-like emulsion particles (-68%). This was associated with an increased post-heparin lipoprotein lipase (LPL) activity (+110%) and an increased uptake of VLDL-derived fatty acids by skeletal muscle, white adipose tissue, and liver. Concomitantly, fenofibrate markedly increased the VLDL-TG production rate (+73%) but not the VLDL-apolipoprotein B (apoB) production rate. Kinetic studies using [(3)H]palmitic acid showed that fenofibrate increased VLDL-TG production by equally increasing incorporation of re-esterified plasma fatty acids and liver TG into VLDL, which was supported by hepatic gene expression profiling data. We conclude that fenofibrate decreases plasma TG by enhancing LPL-mediated VLDL-TG clearance, which results in a compensatory increase in VLDL-TG production by the liver.

    Patients with cancer are at an increased risk for venous thromboembolism (VTE). The risk varies markedly in different patient populations. Factor V (FV) Leiden is the most common genetic risk factor for VTE, and the impact of FV Leiden on cancer-associated thrombosis is not yet fully elucidated. To study the impact of FV Leiden on the risk of thrombosis in cancer patients. In the prospective observational Vienna Cancer And Thrombosis Study (CATS), 982 patients were included and were followed until occurrence of VTE or death, for a maximum period of 2 years. FV Leiden was determined by genotyping at inclusion. Main outcome measures were symptomatic or lethal objectively confirmed VTE. Of the 982 patients, FV Leiden was diagnosed in 72 (7.3%, 70 were heterozygous and 2 were homozygous). Ten of 72 (13.9%) patients with FV Leiden developed VTE, whereas this was the case in 69 of 910 (7.6%) patients without FV Leiden. In multivariate analysis that included age, sex, different tumor types, tumor stage, newly diagnosed vs. recurrence of disease, and the treatment modalities, the hazard ratio was 2.0 (95% confidence interval 1.0-4.0). In Kaplan-Meier analysis, the probability for development of VTE was 13% in those with and 5.7% in those without FV Leiden after 6 months; after 1 year, the corresponding risks were 15% and 7.3%. FV Leiden is a genetically determined and thus disease-independent parameter, which is associated with VTE in cancer patients and could therefore be used for individual risk assignment. © 2014 International Society on Thrombosis and Haemostasis.

    A look up at the night sky reveals a treasury of wonders. Even to the naked eye, the Moon, stars, planets, the Milky Way and even a few star clusters and nebulae illuminate the heavens. For millennia, humans struggled to make sense of what's out there in the Universe, from all we can see to that which lies beyond the limits of even our most powerful telescopes. Beyond the Galaxy traces our journey from an ancient, Earth-centered Universe all the way to our modern, 21st century understanding of the cosmos. Touching on not only what we know but also how we know it, Ethan Siegel takes us to the very frontiers of modern astrophysics and cosmology, from the birth of our Universe to its ultimate fate, and everything in between.

  1. Mind the gap: Griffith University's approach to the governance of ethical conduct in human research.

    2007-01-01

    It is perhaps not coincidental that, at the same time the apparent institutional risks associated with the conduct of human research are increasing, so are the complaints from researchers about research ethics committees. Rather than seeking to implement systems that more efficiently catch wrong-doing, in 2003 Griffith University began implementing an alternative approach. This new approach focused on resourcing the reflective practice of researchers through every stage of their work--well before, and long after, they seek ethical clearance for that work. Institutions have a key role to play in human research ethics, and this can be usefully situated within the broader framework of the institution's governance framework. This paper summarises the new approach that Griffith University adopted in 2003, the implementation of this 'model', the experience to date, and the road ahead.

    The aim of this study is to analyze the simulated behavior of universal spacer in Dynesys dynamic stabilization system inserted in human vertebra. Dynesys, so-called "Dynamic neutralization system for the spine", dynamic stabilization system is a new concept in the surgical treatment of lower back pain recently. Universal spacer used as flexible material is to stabilize the spine and the material property of universal spacer is polycarbonate urethane. Universal spacer may apply different kinematic behaviors at implanted level in vertebra. Spinal range of motion(SROM) of inter-vertebra with installed Dynesys dynamic stabilization system was studied using Adams+LifeMOD as simulation software package. The vertebra model was set up to closely resemble the in-vivo conditions. Inter-vertebra rotations were measured by post processor of Adams and compared with the intact values. SROMs of the flexion, extension, lateral bending, and axial rotation of human virtual models were measured, where three spinal fixation systems such as rigid system, Dynesys system, and fused system were installed. As a result, the value of SROM is decreased in flexion-extension and lateral bending when the spinal fixation system is implanted. The movement of Dynesys system is similar to that of intact model by allowing the movement of lumbar. This means that the Dynesys system is proved to be safe and effective in the treatment of unstable spinal condition.

    Full Text Available Introduction: Human resources development is one of the most important components of any organization and detecting important factors influencing human resources management plays an essential role in the success of the firms. In this study, we investigated different factors influencing human resources productivity of Shiraz University of Medical Sciences staff. Method: The present research was a cross-sectional study. Sample size was calculated 208 individuals. To access information about the human resource productivity, a valid and reliable questionnaire was used. The data were analyzed using SPSS software. Pearson correlation was used for statistical analysis of the data (p=0.05. Results:The results showed that there was a statistically significant relationship (p-value<0.001 between human resources productivity and factors affecting the productivity of human resources (motivational factors, leadership style, creativity and innovation, general and applied education, and competitive spirit. Motivational factors (r =0.89 and general education (r =0.65 had the most and the least effects on human resources productivity. Conclusion: Considering the fact that motivational factors were the most effective factors on human resource productivity, we recommend that managers should care more than before about this factor; also, in order to motivate the employees, they should consider the staff’s individual differences.

    The factor V Leiden mutation is associated with ischemic stroke in children but not in adults. Whether it is associated with ischemic stroke in young adults, however, is uncertain. To address this issue, we performed a meta-analysis of 18 case-control studies of ischemic stroke in adults 50 years of age and younger published before June 2009. Across all studies, factor V Leiden was detected in 154 of 2045 cases (7.5%) and 217 of 5307 controls (4.1%), yielding a fixed-effect odds ratio of 2.00 (95% CI, 1.59-2.51). However, further analyses revealed substantial heterogeneity among these studies (P=0.005 for Q-test of heterogeneity). Hypothesizing that this heterogeneity could be related to differences among studies in case selection criteria, we stratified the meta-analysis into studies for which case samples were enriched or not enriched to include cases having an increased likelihood of prothrombotic genetic involvement ("selected" ischemic stroke studies, n=9) and those that recruited cases from consecutive neurology referrals or hospitalizations ("unselected" ischemic stroke studies, n=8). Among the 9 "selected" ischemic stroke studies, factor V Leiden was more strongly associated with stroke (OR, 2.73; 95% CI, 1.98-3.75), whereas among the 8 "unselected" ischemic stroke studies, the association between factor V Leiden and stroke was substantially weaker (OR, 1.40; 95% CI, 0.998-1.95). This difference was found to be statistically significant (P=0.003 for Woolf test for heterogeneity). We conclude that factor V Leiden is associated with ischemic stroke in young adults, particularly in patient populations in which there is an increased clinical suspicion of prothrombotic state.

    MF will talk about his new book The Human Touch, in which he argues that our understanding of the universe is based upon a paradox. On the one hand, we all agree that humankind is a tiny and insignificant local anomaly. On the other hand, it is impossible to have any concept of the universe except through the constructions that human beings have placed upon it. Without human beings there would be no words or language. Would there still be numbers, if there were no one to count them? Or scientific laws, if there were no words or numbers in which to express them? Would the universe even be vast, without the very fact of our smallness and insignificance to give it scale? Could it have any expression in space and time at all, except in relation to our being where we are when we are? Some of these questions are no longer purely abstract, but are becoming of practical interest to cosmologists and physicists.

A detecção do fator V de Leiden em pacientes portadores de eventos trombóticos é recomendado para esclarecimento das causas e para efetuar o rastreamento em membros de sua família, ainda sem o aparecimento de eventos trombóticos, de forma a avaliar os riscos associados e assim determinar um acompanhamento médico preventivo.Factor V Leiden is a mutation that can cause venous thrombosis. When associated to other risk factors such as the use of contraceptives, important surgical intervention, pregnancy and malignant diseases, the risk for heterozygous carriers increases by three-fold to 10 times or even 80 times for two mutated alleles. The factor V Leiden is found in about 20% of the population with a history of venous thromboembolism. It is present in about 4 to 6% of general population but this percentage changes depending on the ethnicity. This study shows the distribution of alleles in family members of three carriers of factor V Leiden diagnosed with deep venous thrombosis. The mutation investigation of the factor V Leiden gene was performed in 21 family members of 3 heterozygous carriers.

    The authors describe the development and implementation of a University of California (UC) system of oversight, education, tracking, and accountability for human anatomical specimen use in education and research activities. This program was created and initially implemented at UC Davis in 2005. Several incidents arising out of the handling of human anatomical specimens at UC campuses revealed significant challenges in the system for maintaining control of human anatomical specimens used in education and research. These events combined to undermine the public perception for research and educational endeavors involving anatomical materials at public institutions. Risks associated with the acquisition, maintenance, and disposal of these specimens were not fully understood by the faculty, staff, and students who used them. Laws governing sources of specimens are grouped with those that govern organ procurement and tissue banking, and sometimes are found in cemetery and funeral regulations. These variables complicate interpretations and may hinder compliance. To regain confidence in the system, the need to set appropriate and realistic guidelines that mitigate risk and facilitate an institution's research and educational mission was identified. This article chronicles a multiyear process in which diverse stakeholders developed (1) a regulatory policy for oversight, (2) a policy education program, (3) procedures for tracking and accountability, and (4) a reporting and enforcement mechanism for appropriate and ethical use of human anatomical specimens in university education and research.

    Full Text Available O artigo analisa os paralelos entre o retrato do 'sujeito moderno em crise' visto no romance Die Leiden des jungen Werthers de Goethe e, por outro lado, o perfil psicossocial do 'homem do sentimento' do século XVIII, fruto da cultura da Empfindsamkeit. Defendo a perspectiva de que, no romance, Goethe não apenas se utiliza do formato literário mais tradicional da Empfindsamkeit (o do romance epistolar, como também se apropria de topói e técnicas discursivas que lhe são próprias em registro radicalmente heterodoxo. A argumentação nos ligará a uma dedução da visão do conceito de subjetividade moderna com que Goethe trabalha em sua fase final do Sturm und Drang, e que o situa como importante nome do discurso filosófico da modernidade.

    The epidemiology of deep vein thrombosis in adolescents has 2 potential associations. First, there is a demonstrated association with a congenital anomaly of the inferior vena cava (Dean SM, Tytle TL. Vas Med. 2006;11:165-169; Schnieider JG, Eynatten MV, Dugi KA, et al. J Intern Med. 2002;252:276-280). Secondly, resistance to activated protein C as a result of factor V Leiden is associated with thromboembolic disease at an early age (Price DT, Ridker PM. Ann Intern Med. 1997;127:895-903). Imaging modalities, central venous catheters, and improved life expectancy for critically and chronically ill children have resulted in an increased diagnosis of thromboembolic disease in the pediatric population (Journeycake MM, Manco-Johnson MJ. Hematol Oncol Clin N Am. 2004;18;1315-1338), and evaluation for thrombophilia should be performed for any child with thromboembolic disease.

    Factor V Leiden (FVL) mutation is the most common hereditary thrombophilia. Association of this mutation with venous thrombosis is well established. However, there are several conflicting results regarding the association of FVL with arterial thrombosis, acute coronary syndrome, and intracardiac thrombosis. In this case report, we present a 44-yearold male patient with a medical history of both arterial and venous thrombosis who came to our emergency department with chest pain. After the initial evaluation he was diagnosed as having acute coronary syndrome and transthoracic echocardiography revealed an intracardiac apical thrombus. Coronary angiography showed non-critical stenosis. Thrombophilia panel was studied and the patient was found to be heterozygotic for FVL mutation. An apical thrombus was extracted surgically because of the high risk of systemic embolization.

    To evaluate the performance of a Russell viper venom-based activated protein C resistance (APCR) screening test relative to DNA analysis for the factor V Leiden mutation. We evaluated the concordance between Pefakit APCR screening results and DNA analysis for 435 patients homozygous (n = 11), heterozygous (n = 310), or wild-type (n =114) for the G1691A allele. Using receiver operating characteristic analysis, we found that a cutoff of 1.89 for the APCR ratio yields a sensitivity and specificity of 99.1%. In patients with discrepant genotype-phenotype correlation, their APCR may provide a more clinically relevant result. We compared several strategies for employing reflex testing and found that performing initial APCR screening followed by confirmatory molecular analysis on a subset of cases in the borderline regions between the diagnostic groups can reduce unnecessary testing by approximately 80% without compromising diagnostic accuracy.

    Recurrent pregnancy loss is usually defined as the loss of two or more consecutive pregnancies before 20 weeks of gestation, which occurs in approximately 5% of reproductive-aged women. It has been suggested that women with thrombophilia have an increased risk of pregnancy loss and other adverse pregnancy outcomes. Thrombophilia is an important predisposition to blood clot formation and is considered as a significant risk factor for recurrent pregnancy loss. The inherited predisposition to thrombophilia is most often associated with factor V Leiden mutation, prothrombin G20210A mutation, and methylenetetrahydrofolate reductase C677T and A1298C gene variants. The net effect is an increased cleavage of prothrombin to thrombin and excessive blood coagulation. PMID:26989729

    The risk of venous thromboembolism is enhanced in pregnant carriers of the Factor V Leiden mutation. The primary aim of the study was to compare prothrombin fragments 1+2, soluble fibrin and D-dimer levels in pregnant Factor V Leiden mutation carriers with those in non-carriers. Secondary aims were to evaluate whether these biomarkers could predict placenta-mediated complications or venous thromboembolism, and to study blood coagulation after caesarean section with thromboprophylaxis and after vaginal delivery without thromboprophylaxis. Prothrombin fragments 1+2, soluble fibrin and D-dimer levels were studied longitudinally in 476 carriers with singleton pregnancies from gestational weeks 23-25 until 8-10 weeks postpartum. Prothrombin fragments 1+2 and D-dimer levels gradually increased during pregnancy. D-dimer levels were higher in carriers, both during pregnancy and puerperium, compared to non-carriers. D-dimer levels above 0.5mg/l were found in about 30% and 20% of the heterozygous carriers at 4-5 and 8-10 weeks postpartum, respectively. Soluble fibrin levels were mainly unchanged during pregnancy, with no difference between carriers and non-carriers. Biomarker levels were similar in carriers with uncomplicated and complicated pregnancies. Higher D-dimer levels indicate increased blood coagulation and fibrinolysis activity in carriers. The high proportion of carriers with D-dimer levels exceeding 0.5mg/l postpartum must be considered when assessing the probability of venous thromboembolism. Large overlaps in biomarker levels in normal and complicated pregnancies suggest that these biomarkers cannot be used as predictors. Thromboprophylaxis following caesarean section may prevent increased activation of blood coagulation. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The Universal Declaration on Bioethics and Human Rights represents a significant milestone in the history of Law, particularly in the application of International Law to an important area of human activity, namely the medical sciences, the life sciences and the technologies which, linked to both, can be applied to human relations. In parallel with this, and as will be analysed in this article, the Declaration has involved adopting a clear position regarding cultural diversity and pluralism in relation to Biomedicine. In this paper the author highlights the fact that perspectives have been opened which have hardly been explored concerning Biomedicine, such as the recognition of the value and respect which cultural diversity (multiculturalism), economic and social diversity deserve in relation to the issues covered by the Declaration, and the acceptance that the owners of the rights are not only individuals, but can also be groups.

    The advent of geographic online social networks such as Foursquare, where users voluntarily signal their current location, opens the door to powerful studies on human movement. In particular the fine granularity of the location data, with GPS accuracy down to 10 meters, and the worldwide scale of Foursquare adoption are unprecedented. In this paper we study urban mobility patterns of people in several metropolitan cities around the globe by analyzing a large set of Foursquare users. Surprisingly, while there are variations in human movement in different cities, our analysis shows that those are predominantly due to different distributions of places across different urban environments. Moreover, a universal law for human mobility is identified, which isolates as a key component the rank-distance, factoring in the number of places between origin and destination, rather than pure physical distance, as considered in some previous works. Building on our findings, we also show how a rank-based movement model accura...

The question is whether we need all these ranking systems? Are the outcomes of these ranking systems as different as they claim? This study collected data from the results of seven major ranking systems including Shanghai, QS, 4International, Webometrics, HEEACT, and Leiden University ranking and analyzed them. Results showed a significant correlation among the outcomes of these international ranking systems in ranking and rating the world's top 50 universities. The highest correlation was between Shanghai - THE (Spearman's Rho = 0.85; Shanghai - Webometrics (Spearman's Rho = 0.81 and Shanghai - Leiden (Spearman's Rho = 0.80. Finally, some suggestions for improving current ranking systems have been investigated.

The analysis of bioclimate was carried out, using the physiologically equivalent temperature (PET, which is based on the energy balance model of the human body. The meteorological data required for the calculation of PET concern hourly values of air temperature, relative humidity, wind speed and total solar radiation, for the time period 1999–2007. The recorded data sets were obtained from the meteorological station of the Laboratory of Climatology and Atmospheric Environment of the University of Athens. The results revealed the hours of the day in which thermal comfort or stress prevails, as well as the trends and variability of PET, for the studied period. Finally, the intense heat waves occurred during summer 2007 along with extreme cold conditions during December 2003-February 2004 were analyzed in terms of PET classes and compared to the respective average bioclimatic conditions of the study period.

    Innovation in the previous century resulted in development of useful products ranging from automobiles and aircraft to cellular phones. However, the innovation and development of science and technology have changed the society and brought about negative issues. The issues emerged in the previous century remain in the excessive forms in the 21st century. The 21st century is seeing the rise of knowledge-based society, and paradigm shift is now going on. Human resources of university for creation of innovation are being called on to contribute to solving issues. Young people who pass through a doctor program must play a role as an innovator who can promote the paradigm shift. However, the higher education system of the universities in Japan is now required to be changed to dissolve the mismatch on the doctor program with industries, government and students. The discussion in the Business-University Forum of Japan for innovation of education system and a few challenges of the Nagoya University are introduced in this paper.

    ABO blood type locus has been reported to be an important genetic determinant of venous and arterial thrombosis in genome-wide association studies. We tested the hypothesis that ABO blood type alone and in combination with mutations in factor V Leiden R506Q and prothrombin G20210A is associated with the risk of venous thromboembolism and myocardial infarction in the general population. We used data from 2 Danish studies that followed members of the general public from 1977 through 2010. We obtained the genotype of 66 001 white participants for ABO blood type, factor V Leiden R506Q and prothrombin G20210A. We calculated hazard ratios (HRs) and population attributable risk. Our main outcome measures were venous thromboembolism and myocardial infarction. The multivariable adjusted HR for venous thromboembolism was 1.4 (95% confidence interval [CI] 1.3-1.5) for non-O blood type (v. O blood type). For the factor V Leiden R506Q mutation, the adjusted HR was 2.2 (95% CI 2.0-2.5) for heterozygous participants and 7.0 (95%CI 4.8-10) for homozygous participants (v. participants without the mutation). For prothrombin G20210A, the adjusted HR was 1.5 (95%CI 1.2-1.9) for heterozygous participants and 11 (95% CI 2.8-44) for homozygous participants (v. participants without the mutation). When we combined ABO blood type and factor V Leiden R506Q or prothrombin G20210A genotype, there was a stepwise increase in the risk of venous thromboembolism (trend, pfactor V Leiden R506Q and 1% for prothrombin G20210A. Multivariable adjusted HRs for myocardial infarction by genotypes did not differ from 1.0. ABO blood type had an additive effect on the risk of venous thromboembolism when combined with factor V Leiden R506Q and prothrombin G20210A mutations; blood type was the most important risk factor for venous thromboembolism in the general population.

    Homozygous or double heterozygous factor V Leiden and/or prothrombin G20210A is a rare inherited thrombophilic trait. Whether individuals with this genetic background have an increased risk of recurrent venous thrombosis is uncertain. A case-control design within a large cohort of families with thrombophilia was chosen to calculate the risk of recurrent venous thrombosis in individuals with homozygosity or double heterozygosity of factor V Leiden and/or prothrombin G20210A. Cases were individuals with recurrent venous thrombosis, and controls were those with only 1 venous thrombosis. The cohort consisted of 788 individuals with venous thrombosis; 357 had factor V Leiden, 137 had prothrombin G20210A, 27 had factor V Leiden and/or prothrombin G20210A homozygosity, and 49 had double heterozygosity for both mutations. We identified 325 cases with recurrent venous thrombosis and 463 controls with only 1 venous thrombosis. Compared with noncarriers, crude odds ratio for recurrence was 1.2 (95% confidence interval, 0.9 to 1.6) for heterozygous carriers of factor V Leiden, 0.7 (95% confidence interval, 0.4 to 1.2) for prothrombin G20210A, 1.2 (95% confidence interval, 0.5 to 2.6) for homozygous carriers of factor V Leiden and/or prothrombin G20210A, and 1.0 (95% confidence interval, 0.6 to 1.9) for double heterozygotes of both mutations. Adjustments for age, sex, family status, first event type, and concomitance of natural anticoagulant deficiencies did not alter the risk estimates. In this study, individuals with homozygous factor V Leiden and/or homozygous prothrombin G20210A or double heterozygous carriers of factor V Leiden and prothrombin G20210A did not have a high risk of recurrent venous thrombosis.

    This article aims to explore the increasing interconnection between bioethics and human rights that can be observed in recent international norms relating to biomedicine. To this end, the analysis has been focused on the Universal Declaration on Bioethics and Human Rights (UDBHR) adopted by UNESCO in 2005. Investigating the meanings of the intersection perceived in the UDBHR has led to the understanding of how bioethics and human rights are in accordance, under the normative perspective. Hence, in normative terms, the intersection between bioethics and human rights is clearly undisputable. However, there is no way to affirm that it is consolidated, as UDBHR's adoption is recent and its consolidation, together with its precepts, depends on state and non-state agents. The efficacy of a norm and its content depends on social, cultural and economic conditions, that is, it depends on a series of factors that influence the normative system. In the case of the UDBHR, its effective application and assimilation of its principles are directly linked to the use that bioethical institutions make of them and to how the community of bioethicists will project them in their thoughts and theory production. If, on the one hand UDBHR symbolizes the intersection confirmation--which is of extreme importance for its consolidation--on the other hand its range and consequent stabilization are submitted to the actions from governments, social institutions and bioethicists. Hence, there is still a lot to do in terms of introducing the human rights precepts into bioethics. The aim of this paper is to contribute to this goal. Thus based on the meanings of the intersection between bioethics and human rights identified in the UDBHR, this article presents five ways to understand the connection between these two fields.

    To examine gender differences in human papillomavirus (HPV) vaccine stages of change following the recommendations for permissive use of HPV vaccine in males. Students aged 18-26 attending a large, public, Midwest university in April 2010. Participants completed a self-administered, online questionnaire. HPV vaccine stage of change was assessed according to core constructs of the Transtheoretical Model of Behavior Change. Logistic regression was used to identify associations of HPV-related beliefs and attitudes with stage of change. Although most (80.5%) of the 4,019 participants had at least contemplated HPV vaccination, more females had taken observable steps towards vaccination. Significant differences between genders in HPV-related beliefs and attitudes were observed, particularly perceived parental or perceived health care provider approval of HPV vaccination. University students generally agreed with the benefits of HPV vaccination, both for themselves and for society, and these attitudes were significantly associated with having at least contemplated vaccination.

  11. The interface between bioethics and cultural diversity under the Universal Declaration on Bioethics and Human Rights.

    2008-06-01

    The Universal Declaration on Bioethics and Human Rights has made clear its aims to provide a universal framework of principles and procedures to guide States in the formulation of their legislation, policies or other instruments in the field ofbioethics and also to guide the actions of individuals, groups, communities, institutions and corporations so as to promote appreciation for human dignity and to protect human rights. It also sets up 15 principles to be applied. One of the principles in the Declaration is about the recognition of cultural diversity as an important element of bioethics. Thus it is clear that bioethics has its relativeness and is susceptible to different cultures. However, in order not to have the bioethics principles being defeated because of the cultural factor, the Declaration set forth conditions to limit the application of the cultural diversity element. This approach is called "qualified absoluteness" by the author. The paper discusses these conditions and the problems arising from their applications. Basically, there is a clear line drawn to limit the application of cultural diversity in setting up and in applying bioethical rules. The line drawn is based on the concept of human rights, the principles and concepts of which have not only been set forth in the Human Rights Convention, but have also been prescribed in other provisions in the Declaration. From conceptual viewpoint, the Declaration has listed a number of soft-law rules, which in turn also provide authorization for the government or private or public groups to take cultural diversity into account. Although the rules set forth in most of the parts in the Declaration are of soft but absolute mandates in nature, the requirement of paying due regard to cultural diversity is in fact providing governments as well as groups a possibility to enact or apply their bioethical rules to reflect their cultural uniqueness. The term "qualified absoluteness" is used in this paper to reflect

    Factor V Leiden and prothrombin G20210A are the two most prevalent causes of inherited thrombophilia. The prevalence of these mutations varies widely in healthy Caucasian population. The aim of our study was to determine the frequency of factor V Leiden and prothrombin G20210A mutations in Slovak and Roma ethnic group from Eastern Slovakia. We analyzed 540 asymptomatic individuals (269 individuals of Slovak ethnicity and 271 individuals of Roma ethnicity) by real-time PCR method. The detected allele frequencies were 2.97 versus 6.64 % for factor V Leiden (p = 0.0049), and 0.74 versus 0.92 % for prothrombin mutation (p = 0.7463) in Slovak and Roma population, respectively. The Roma ethnic group had significantly higher prevalence of factor V Leiden mutation when compared to Slovak ethnic group. The allele frequency of factor V Leiden in ethnic Romanies from Eastern Slovakia was one of the highest in Europe. Our results confirm an uneven geographical and ethnic distribution of factor V Leiden.

    Full Text Available OBJECTIVE: Migraine is an independent risk factor for ischemic stroke, but its pathophysiology is still unclear. Genetic factors that predispose patients to thrombosis have been studied in patients with migraine to highlight the pathogenesis, but the results remain controversial. In this study, the frequencies of factor V Leiden (FVL, prothrombin (Pt G20210A and methylenetetrahydrofolate reductase (MTHFR C677T mutations were investigated. METHODS: One hundred and sixty patients aged of 15 to 55 years with no history of systemic disease and who had been diagnosed as migraine according to the International Headache Society (IHS diagnostic criteria at Baskent University Hospital Neurology Outpatient Clinics were investigated for FVL, Pt G20210A and MTHFR C677T mutations from their genomic DNA, and the results were compared with those of healthy controls. RESULTS: One hundred and fifty five (96.9% of 160 migraine patients were homozygote normal, 5 (3.1% were heterozygote and none of them were homozygote mutant for FVL. The control group had 9.8% heterozygote individuals but the difference between the percentages was not statistically significant (p> 0.05. There were no homozygote mutant individuals in the Turkish population study in normal subjects like our study. Thirty nine (24.4% of 160 migraine patients were heterozygote and 8 (5% were homozygote mutant for MTHFR C677T. The control group had 37 (34.9% heterozygote and 6 (5.6% homozygote mutant individuals. The difference between the percentages was not statistically significant (p= 0.15. Three (1.9% of 160 migraine patients were heterozygote and 5 (2.9% of the control group were heterozygote mutant for Pt G20210A mutation. The control group had 37 (34.9% heterozygote and 6 (5.6% homozygote mutant individuals. The difference between the percentages was not statistically significant (p= 0.420.

    Full Text Available Abstract Background Affecting the core functional microbiome, peculiar high level taxonomic unbalances of the human intestinal microbiota have been recently associated with specific diseases, such as obesity, inflammatory bowel diseases, and intestinal inflammation. Results In order to specifically monitor microbiota unbalances that impact human physiology, here we develop and validate an original DNA-microarray (HTF-Microbi.Array for the high taxonomic level fingerprint of the human intestinal microbiota. Based on the Ligase Detection Reaction-Universal Array (LDR-UA approach, the HTF-Microbi.Array enables specific detection and approximate relative quantification of 16S rRNAs from 30 phylogenetically related groups of the human intestinal microbiota. The HTF-Microbi.Array was used in a pilot study of the faecal microbiota of eight young adults. Cluster analysis revealed the good reproducibility of the high level taxonomic microbiota fingerprint obtained for each of the subject. Conclusion The HTF-Microbi.Array is a fast and sensitive tool for the high taxonomic level fingerprint of the human intestinal microbiota in terms of presence/absence of the principal groups. Moreover, analysis of the relative fluorescence intensity for each probe pair of our LDR-UA platform can provide estimation of the relative abundance of the microbial target groups within each samples. Focusing the phylogenetic resolution at division, order and cluster levels, the HTF-Microbi.Array is blind with respect to the inter-individual variability at the species level.

    From an historical perspective, this text presents an entirely non- mathematical introduction to astronomy from the first endeavours of the ancients to the current developments in research enabled by cutting edge technological advances. Free of mathematics and complex graphs, the book nevertheless explains deep concepts of space and time, of relativity and quantum mechanics, and of origin and nature of the universe. It conveys not only the intrinsic fascination of the subject, but also the human side and the scientific method as practised by Kepler, defined and elucidated by Galileo, and then demonstrated by Newton.

    Full Text Available This article discusses the Right to the City, in a conceptual dimension and wide, and his dialectical relationship with the Universal Declaration of Human Rights of 1948 and its universalism and cultural relativism categories. The Right to the City (RtC is capitula- ted as one of the categories of the Human Right to Development from the compartments on Human Rights to descend from the Universal Declaration of Human Rights. Linked to this assumption, the discussion of universalism and cultural relativism theories bring to the fore important questions and considerations as to RtC condition, since in its current design and trampled by an evil legacy of neoliberalism, this right has demonstrated the need for authoritative action of the State, given the nature of fundamental human right of the third dimension. Through RtC, boasts up of economic, social and cultural rights, requiring a positive action of the state as compliance guarantee this human right. In this bias, relevant are discussions about the concept of law, morality, liberalism, effectiveness and universality of human rights theories and cultural relativism in dialectic with the RtC and its complexity. It starts from the assumption that the Universal Declaration of Human Rights and other statements which have descended universality (despite criticism, however, this har- vest, it is imperative closer examination of the concept, forecast, guarantee and effective- ness fundamental human rights, which may lead to a mixed application of universalistic and relativistic theories when analyzed from the perspective of these institutes.

    Impairment of the protein C pathway, detectable by reduced plasma levels of activated protein C (APC), are risk factors for venous thrombosis. Activated protein C maintains clotting homeostasis by regulation of pro-coagulant factors Va and VIIIa. Both infection and the factor V Leiden mutation reduce the formation of APC from protein C in the blood. With low levels of APC, excess factors Va and VIIIa exist, increasing the risk of thrombus formation. Livedo racemosa is characterised by a striking, violaceous branch-like pattering of the skin. It is similar to livedo reticularis, but with a different morphology and histopathology. In this case report we present the first case of livedo racemosa, in an 89-year-old factor V Leiden-positive patient with a Pseudomonas aeruginosa urinary tract infection. The cutaneous biopsies demonstrated vasculopathy with intraluminal thrombi in subcutaneous vessels with no evidence of inflammatory vasculitis.

    We analysed the prevalence of the most common hereditary thrombophilia (hTP) - factor V Leiden (FVL) mutation, prothrombin 20210 G>A substitution (PT) - and the 677 C>T replacement in the 5,10-methylenetetrahydrofolate reductase (MTHFR) gene in Caucasian patients with a history of two and more consecutive recurrent miscarriages (RMs) as compared to healthy controls with an identical ethnic background and at least one live birth. A multicenter analysis of three hTP was performed in 641 RM patients identically screened at specialized university centres. The study groups consisted of 240 patients with 2 (1) and 401 patients with >2 miscarriages (2) and were compared with 157 controls. There was no significant difference in the prevalence of the hTP between RM patients and controls nor within the two study groups. Subgroup analysis showed that the homozygous MTHFR polymorphism was significantly more prevalent in the study group 2 as compared to study group 1 (13.9 versus 7.9%, P = 0.02). In Caucasians, maternal FVL or PT mutations do not seem to contribute to the pathophysiology of RM, irrespective of the number of miscarriages. However, the role of the homozygous MTHFR polymorphism merits further investigation. © 2013 John Wiley & Sons Ltd.

    We present the final data release of observations of lambda 21-cm emission from Galactic neutral hydrogen over the entire sky, merging the Leiden/Dwingeloo Survey (LDS: Hartmann & Burton, 1997) of the sky north of delta = -30 deg with the Instituto Argentino de Radioastronomia Survey (IAR: Arnal et al., 2000, and Bajaja et al., 2005) of the sky south of delta = -25 deg. The angular resolution of the combined material is HPBW ~ 0.6 deg. The LSR velocity coverage spans the interval -450 km/s to +400 km/s, at a resolution of 1.3 km/s. The data were corrected for stray radiation at the Institute for Radioastronomy of the University of Bonn, refining the original correction applied to the LDS. The rms brightness-temperature noise of the merged database is 0.07 - 0.09 K. Residual errors in the profile wings due to defects in the correction for stray radiation are for most of the data below a level of 20 - 40 mK.

    Background: reduced telomere length in blood cells has been associated with increased risk of multiple age-related diseases and is widely regarded as a general biomarker of ageing. Therefore, it is important to know both the extent and limitations of this association. We investigated the relation between telomere length and anaemia in two independent cohorts, with the prior expectation of adding anaemia to the list of conditions for which telomere reduction is a risk factor. Participants and methods: the present study is embedded in the Newcastle 85-plus Study and Leiden 85-plus Study, two population-based studies of inhabitants of Newcastle and North Tyneside, UK (n = 749) and Leiden, the Netherlands (n = 658) aged 85 and over. High-molecular-weight DNA was isolated from full fresh blood (Newcastle) and peripheral blood mononuclear cells samples (Leiden). Telomere length was measured as abundance of telomeric template versus a single gene by quantitative real-time polymerase chain reaction. Anaemia was defined according to World Health Organization criteria. Results: in both studies, no differences in median telomere length were observed between participants with anaemia and participants without anaemia (Newcastle: 2,846 bp (interquartile range (IQR) 2,433–3,630) versus 2,920 bp (IQR 2,425–3,570), P = 0.63; Leiden: 4,136 bp (IQR 3,879–4,428) versus 4,167 bp (IQR 3,893–4,501), P = 0.41). Telomere length also did not correlate with any other haematological parameter in both men and women. Conclusions: in contrast to other age-related diseases, telomere length is not associated with anaemia or any other haematological parameter in older individuals in the general population.

    To determine the frequency of Factor V Leiden in cases of Deep Vein Thrombosis and Healthy controls. This case control study was performed in Armed Forces Institute of Pathology Rawalpindi, From 21(st) March to 25(th) September 2013. One hundred patients with diagnostic evidence of Deep vein thrombosis on Doppler ultrasound/Magnetic resonance imaging (MRI) scan were included in the study through non probability convenient sampling and compared with 100 matched healthy controls. DNA was extracted from the blood sample by kit method. In order to identify Factor V Leiden mutation, the polymerase chain reaction (PCR) method was utilized combined with the Amplification refractory mutation system. Data was analyzed using statistical package for social sciences (SPSS) version 17. In 100 patients of Deep Vein Thrombosis (DVT), frequency of Factor V Leiden (FVL) was 13% and it is was 2% in healthy control group. A significant association was found between FVL and DVT with odds ratio of 7.32 and with P value (P = 0.003). FVL was found to be highly prevalent among patients of DVT, Signifying strong association between the two.

    The GeneXpert analyzer is a hands-off system for the detection of Factor V Leiden and of Prothrombin G20210A (GPRO) gene thrombophilic mutations. Although the system is efficient and easy to use, we report the rare possibility of incorrect genotyping. 1648 samples were evaluated using the GeneXpert HemosIL Factor II and Factor V assay: 1319 were freshly analyzed while 329 were frozen, thawed and diluted with saline prior to analysis to avoid clogging of the instrument syringe. Two samples, both heterozygous, one for the factor V Leiden and the other for the GPRO gene, were incorrectly genotyped as homozygous for the relative mutation. Inspection of the Ct values and amplification curves and genotyping with PCR revealed the correct genotype as heterozygous for factor V Leiden and GPRO mutation. The GeneXpert HemosIL Factor II and Factor V assay is an automated, fast genotyping assay requiring almost no sample manipulation, advantageous characteristics if compared with other PCR-based methods. However, an inattentive use of it can generate incorrect diagnosis. A careful handling of the sample, in particular correct dilution of frozen/thawed samples before analysis, and the inspection of the amplification curves and Ct values are required to avoid artifacts.

    Applying a robust human rights framework would change thinking and decision-making in efforts to achieve Universal Health Coverage (UHC), and advance efforts to promote women's, children's, and adolescents' health in East Africa, which is a priority under the Sustainable Development Agenda. Nevertheless, there is a gap between global rhetoric of human rights and ongoing health reform efforts. This debate article seeks to fill part of that gap by setting out principles of human rights-based approaches (HRBAs), and then applying those principles to questions that countries undertaking efforts toward UHC and promoting women's, children's and adolescents' health, will need to face, focusing in particular on ensuring enabling legal and policy frameworks, establishing fair financing; priority-setting processes, and meaningful oversight and accountability mechanisms. In a region where democratic institutions are notoriously weak, we argue that the explicit application of a meaningful human rights framework could enhance equity, participation and accountability, and in turn the democratic legitimacy of health reform initiatives being undertaken in the region.

    Full Text Available This article is an outline toward developing a fuller process theory of human dynamics aimed at practical applications by a diverse audience. The theory represents a transdisciplinary synthesis of a universal pattern and integrates humans’ projection dynamics with complex systems dynamics. Five premises, presented in lay language with examples, capture basic elements involved in the meta process of human development and change: reciprocity, projection, development’s structural limits, oscillations, and structural coupling. Based on a fractal dialectical pattern that shows up wherever complex systems are involved, the theory’s applications are scalable. It could be useful for personal development, public policy design, issue analysis, and systemic action on intransigent issues. It may be a complementary adjunct to developmental stage theories because it deals in an accessible way with the processes involved in stage transitions. Throughout the article, its practical relevance at some individual, social, and political scales is illustrated or mentioned. Readers interested in individual and social change may gain a sense of the human dynamics involved in it, and thus the potential usefulness of a process theory that describes what goes on in human change and development.

    In ancestral sharks, a rapid emergence in the evolution of the immune system occurred, giving jawed-vertebrates the necessary components for the combinatorial immune response (CIR). To compare the natural antibody (NAb) repertoires of the most divergent vertebrates with the capacity to produce antibodies, we isolated NAbs to the same set of antigens by affinity chromatography from two species of Carcharhine sharks and from human polyclonal IgG and IgM antibody preparations. The activities of the affinity-purified anti-T-cell receptor (anti-TCR) NAbs were compared with those of monoclonal anti-TCR NAbs that were generated from a systemic lupus erythematosus patient. We report that sharks and humans, representing the evolutionary extremes of vertebrate species sharing the CIR, have NAbs to human TCRs, Igs, the human senescent cell antigen, and to numerous retroviral antigens, indicating that essential features of the combinatorial repertoire and the capacity to recognize the potential universe of antigens is shared among all jawed-vertebrates.

    2016-01-01

    Full Text Available Venous thromboembolism is a multifactorial disorder with two manifestations: deep-vein thrombosis and pulmonary embolism. Pulmonary embolism is usually considered as the complication of deep-vein thrombosis, but there are reported cases of isolated pulmonary embolism. FV Leiden and FII G20210A mutations are most common genetic risk factors for the venous thromboembolism. Several studies reported "FV Leiden paradox": lower prevalence of FV Leiden mutation among patients with isolated pulmonary embolism than among those with deep-vein thrombosis. The aim of this study was to determine FV Leiden and FII G20210A mutations frequency in thrombophilic patients in Serbian population. We tested prevalence of these mutations carriers in 1427 individuals divided in three groups of patients (with deep-vein thrombosis, deep-vein thrombosis/ pulmonary embolism and isolated pulmonary embolism and control group. All subjects were tested for these mutations using PCR-RFLP analysis. Detected frequency of FV Leiden heterozygous carriers in patients with isolated pulmonary embolism was 6.9% (for FII G20210A 11.6%, while in other two groups of patients with deep-vein thrombosis and deep vein thrombosis/pulmonary embolism, frequency was 18.6% (for FII G20210A mutation were 11.6% and 8.3%, respectively. Our results showed that FV Leiden mutation is less frequent in patients with isolated pulmonary embolism than in patients with deep-vein thrombosis or deep-vein thrombosis accompanied with pulmonary embolism, confirming "FV Leiden paradox". On the other hand, detected frequency of FII G20210A mutation carriers was similar in all three groups of patients. [Projekat Ministarstva nauke Republike Srbije, br. 173008

    Full Text Available Human induced pluripotent stem cells (iPSCs provide a potentially replenishable source for the production of transfusable platelets. Here, we describe a method to generate megakaryocytes (MKs and functional platelets from iPSCs in a scalable manner under serum/feeder-free conditions. The method also permits the cryopreservation of MK progenitors, enabling a rapid “surge” capacity when large numbers of platelets are needed. Ultrastructural/morphological analyses show no major differences between iPSC platelets and human blood platelets. iPSC platelets form aggregates, lamellipodia, and filopodia after activation and circulate in macrophage-depleted animals and incorporate into developing mouse thrombi in a manner identical to human platelets. By knocking out the β2-microglobulin gene, we have generated platelets that are negative for the major histocompatibility antigens. The scalable generation of HLA-ABC-negative platelets from a renewable cell source represents an important step toward generating universal platelets for transfusion as well as a potential strategy for the management of platelet refractoriness.

    Factor V Leiden (FVL) has been associated with ischemic stroke in children but not in adults. Although the FVL mutation is associated with increased risk for venous thrombosis, its association with ischemic stroke in young adults remains uncertain. Therefore, we examined the association between FVL and ischemic stroke in participants of the Genetics of Early Onset Stroke (GEOS) study. A population-based case control study identified 354 women and 476 men 15 to 49 years of age with first-ever ischemic stroke and 907 controls. Participant-specific data included vascular risk factors, FVL genotype and, for cases, the ischemic stroke subtype by modified Trial of ORG 10172 in Acute Stroke criteria. Logistic regression was used to calculate odds ratios for the entire population and for subgroups stratified by risk factors and ischemic stroke subtype. The frequency of the FVL mutation was similar between ischemic stroke patients (3.6%; 95% confidence interval [CI] 2.5%-5.1%) and nonstroke controls (3.8%; 95% CI 2.7%-5.2%). This frequency did not change significantly when cases were restricted to patients with stroke of undetermined etiology (4.1%; 95% CI 2.6%-6.4%). Among young adults, we found no evidence for an association between FVL and either all ischemic stroke or the subgroup with stroke of undetermined etiology. Published by Elsevier Inc.

    Full Text Available Aim. Lebanon exhibits one of the highest prevalences of factor V-Leiden (FVL in the world (14.4%. The aim of this study is to evaluate the incidence of FVL mutation among Lebanese patients with lower extremity venous thrombosis. Material and Methods. From January 2003 to January 2011, 283 consecutive Lebanese patients, diagnosed with deep venous thrombosis (DVT by duplex scan, were retrospectively reviewed. FVL mutation was tested among patients with conditions highly suggestive of hypercoagulation states (65 patients. Results. FVL mutation was detected among 56.9% of patients, 68.6% of patients younger than 50 years, and 43.4% of patients older than 50 years (=0.041. FVL mutation was commonly reported in young adults, in patients with pregnancy, estrogen drugs, recurrent DVT, and resistance to anticoagulation. Conclusion. The high rate of FVL mutation observed among Lebanese patients with venous thrombosis is related to the high prevalence of this mutation in the Lebanese population. Thrombophilia screening should be tailored to accommodate a population's risk factor. In countries with high prevalence of FVL, this mutation should be screened among patients younger than 50 years and patients with situations highly suggestive of hypercoagulation states.

    The factor V Leiden mutation is the most common genetic risk factor for deep vein thrombosis: it is present in about 5% of the white population. The risk of deep vein thrombosis among women who use oral contraceptives is greatly increased by the presence of the mutation. The same seems to be true of the risk of postpartum thrombosis. Several authors have called for all women to be screened before prescription of oral contraceptives and during pregnancy. Such a policy might deny effective contraception to a substantial number of women while preventing only a small number of deaths due to pulmonary emboli. Moreover, in pregnancy the ensuing use of oral anticoagulation prophylaxis might carry a penalty of fatal bleeding that is equal to or exceeds the risk of death due to postpartum thrombosis. It might pay, however, to take a personal and family history of deep vein thrombosis when prescribing oral contraceptives or at a first antenatal visit to detect women from families with a tendency to multiple thrombosis.

    Some studies evaluated the association of factor V Leiden (FVL) with sepsis risk and mortality risk. However, the results were conflicting. Thus, we performed a meta-analysis to address the association between FVL and sepsis. PubMed and EMBASE databases were searched to find relevant studies. Odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were estimated using random effects model. Five case-control studies and 3 cohort studies were included. Overall, no significant association between FVL and sepsis risk was observed (OR = 0.93; 95% CI 0.74-1.15; P = .49). In addition, there was no significant association between FVL and sepsis-related mortality (OR = 1.17; 95% CI 0.73-1.88; P = .52). In the subgroup analysis, no increased sepsis risk and mortality risk were found in caucasian population. This meta-analysis suggested that FVL was not a risk factor for sepsis and sepsis mortality. © The Author(s) 2013.

    Objective The liver is the key organ involved in systemic inflammation, but the relation between hepatic inflammation and atherogenesis is poorly understood. Since nuclear factor-κB (NF-κB) is a central regulator of inflammatory processes, we hypothesized that chronically enhanced hepatic NF-κB activation, through hepatocyte-specific expression of IκB kinase-β (IKKβ) (LIKK), will aggravate atherosclerosis development in APOE*3-Leiden (E3L) mice. Methods and Results E3L.LIKK and E3L control littermates were fed a Western-type diet for 24 weeks. E3L.LIKK mice showed a 2.3-fold increased atherosclerotic lesion area and more advanced atherosclerosis in the aortic root with less segments without atherosclerotic lesions (11 vs. 42%), and more segments with mild (63% vs. 44%) and severe (26% vs. 14 %) lesions. Expression of LIKK did not affect basal levels of inflammatory parameters, but plasma cytokine levels tended to be higher in E3L.LIKK mice after lipopolysaccharide (LPS) administration. E3L.LIKK mice showed transiently increased plasma cholesterol levels, confined to (V)LDL. This transient character resulted in a mild (+17%) increased cumulative plasma cholesterol exposure. Conclusion We conclude that selective activation of NF-κB in hepatocytes considerably promotes atherosclerosis development which is (at least partly) explained by an increased sensitivity to proinflammatory triggers and transiently increased plasma cholesterol levels.

    In 2005 the representatives of 191 states meeting for the General Conference of UNESCO unanimously approved the "Universal Declaration on Bioethics and Human Rights". The Declaration is the only instrument of its kind: it was the first document adopted by a global organisation that addressed the whole range of issues with which bioethics is concerned and that is a legal instrument. Many of the principles affirmed in the Declaration had already been amply absorbed into the discipline of bioethics. All of them can be traced to the dignity and equality of every individual. The most evident novelty is to be found less in the content of the principles than in the balancing of individual and societal perspectives. Also in evidence are several compromises that were adopted in order to promote dialogue and mutual understanding.

    2011-01-01

    UNESCO's Universal Declaration on Bioethics and Human Rights (2005) was drawn up by an independent panel of experts (the International Bioethics Committee) and negotiated by member states. UNESCO aimed for a participatory and transparent drafting process, holding national and regional consultations and seeking the views of various interest groups, including religious and spiritual ones. Furthermore, reflecting UNESCO's broad interpretation of bioethics, the IBC included medics, scientists, lawyers and philosophers among its membership. Nevertheless, several potential stakeholders-academic scientists and ethicists, government policy-makers and NGO representatives-felt they had not been sufficiently consulted or even represented during the Declaration's development. Better communications and understanding within and between national, regional and international layers of governance would help to avoid a recurrence of this problem in future negotiations.

  3. Universal spectrum for DNA base C+G frequency distribution in Human chromosomes 1 to 24

    Power spectra of human DNA base C+G frequency distribution in all available contiguous sections exhibit the universal inverse power law form of the statistical normal distribution for the 24 chromosomes. Inverse power law form for power spectra of space-time fluctuations is generic to dynamical systems in nature and indicate long-range space-time correlations. A recently developed general systems theory predicts the observed non-local connections as intrinsic to quantumlike chaos governing space-time fluctuations of dynamical systems. The model predicts the following. (1) The quasiperiodic Penrose tiling pattern for the nested coiled structure of the DNA molecule in the chromosome resulting in maximum packing efficiency. (2) The DNA molecule functions as a unified whole fuzzy logic network with ordered two-way signal transmission between the coding and non-coding regions. Recent studies indicate influence of non-coding regions on functions of coding regions in the DNA molecule.

  4. Assessing the universal health coverage target in the Sustainable Development Goals from a human rights perspective.

    The UN's Sustainable Development Goals (SDGs), adopted in September 2015, include a comprehensive health goal, "to ensure healthy lives and promote well-being at all ages." The health goal (SDG 3) has nine substantive targets and four additional targets which are identified as a means of implementation. One of these commitments, to achieve universal health coverage (UHC), has been acknowledged as central to the achievement of all of the other health targets. As defined in the SDGs, UHC includes financial risk protection, access to quality essential health-care services, and access to safe, effective, quality and affordable essential medicines and vaccines for all. This article evaluates the extent to which the UHC target in the SDGs conforms with the requirements of the right to health enumerated in the International Covenant on Economic, Social and Cultural Rights, the Convention on the Rights of the Child, and other international human rights instruments and interpreted by international human rights bodies. It does so as a means to identify strengths and weaknesses in the framing of the UHC target that are likely to affect its implementation. While UHC as defined in the SDGs overlaps with human rights standards, there are important human rights omissions that will likely weaken the implementation and reduce the potential benefits of the UHC target. The most important of these is the failure to confer priority to providing access to health services to poor and disadvantaged communities in the process of expanding health coverage and in determining which health services to provide. Unless the furthest behind are given priority and strategies adopted to secure their participation in the development of national health plans, the SDGs, like the MDGs, are likely to leave the most disadvantaged and vulnerable communities behind.

    We have shown that in Mexican mestizo patients with clinical features of primary thrombophilia, 39% have activated protein C resistance phenotype, 5% protein C deficiency, and 2% protein S deficiency. In the present study, in a group of 37 thrombophilic Mexicans and 50 normal controls, we assessed the factor V G1691A (Leiden), the prothrombin G20210A, and the methylenetetrahydrofolate reductase (MTHFR) C677T gene polymorphisms. Four patients were found to be heterozygous for factor V Leiden, 5 heterozygous for the prothrombin 20210, 16 heterozygous, and 6 homozygous for the MTHFR 677. There were four individuals with co-segregation of alleles: two heterozygotes for the factor V Leiden/prothrombin 20210, one heterozygote for prothrombin 20210/MTHFR 677, and one heterozygote for prothrombin 20210/homozygote for MTHFR 677. For factor V Leiden, prothrombin 20210, and MTHFR 677 mutations, the allele frequencies were respectively 1% (+/-0.2%, alpha = 0.05), 7.66 (P mestizo thrombophilic patients, the low prevalence of the factor V Leiden mutation (10.8%) and the high prevalence of the prothrombin 20210 mutation (13.5%) contrast with those identified in Caucasian thrombophilic patients (21% and 6%, respectively; P mestizo patients.

    Recurrent pregnancy loss (RPL) caused by various genetic and non-genetic factors. After chromosome abnormality, thrombophilia is one of the most important genetic factors that could cause RPL. Factor V Leiden and factor II G20210A mutation were the most common mutations cause thrombophilia in the world. The purpose of this study was to determine the frequency of factor V Leiden and prothrombine gene mutations in women with RPL compared with women who had uneventful pregnancies. This case control study evaluates the frequency of factor V-Leiden and factor II G20210 genotypes in 80 women with two or more pregnancy losses, compared with 80 women without adverse pregnancy outcome. The mutations were assessed by PCR-RFLP. Frequency of the factor V Leiden among cases was 2.5%, which was higher than controls (1.25%), but the difference was not significant. No factor II G20210 mutation was found among cases and controls. These data did not confirm that factor V Leiden and factor II G20210 mutation might play a role in recurrent pregnancy loss in Iranian women.

    In order to determine the frequencies of factor V Leiden and prothrombin G20210A point mutations in the Iranian population with Azeri Turkish origin. 120 unrelated individuals from general population randomly selected and were examined for factor V Leiden and prothrombin G20210A mutations using a multiplex allele specific polymerase chain reaction (MAS-PCR) assayOutcomes: The frequency of prothrombin G20210A mutation was 2.08%, which means 5 chromosomes out of 240 chromosomes had prothrombin G20210A mutation. The distribution of prothrombin 20210 GG, GA, AA genotypes and prothrombin 20210A allele were 37(92.5%), 3(7.5%), 0(0%) and 3(3.75%) in males and 78(97.5%), 2(2.5%), 0(0%) and 2(1.25%) in females, respectively. Factor V Leiden was not found in our tested group (zero chromosomes out of 240 chromosomes). Analysis of the observed frequencies in the studied groups indicates that there is no statistically significant difference between females and males, regarding prothrombin G20210A mutation (p value>0.05). This is the first study in its own kind in this population and implies that the frequency of Factor V Leiden G1691A (R506Q, FV-Leiden) allele is extremely low but the prothrombin G20210A mutation is more frequent in the tested group.

    Factor V Leiden 1691G/A and prothrombin gene 20210G/A mutations are the most common genetic defects leading to thrombosis. This work aimed to study the FV Leiden and the prothrombin gene polymorphism in adult Egyptian patients with acute leukemia and their importance in thrombophilia screening. The study included 76 patients with acute leukemia and 100 healthy controls. Genotyping was done by real-time polymerase chain reaction technique. For factor V Leiden, the frequency of G/A mutation conferred more than 2.5-fold of increased risk of (OR 2.639 95 % CI 1.045-6.669). The frequency of factor V Leiden combined (G/A + A/A) genotypes conferred 2.83-fold of increased risk (OR 2.828, CI 1.13-7.075), The A allele conferred almost threefold increased risk (OR 2.824, 95 % CI 1.175-6.785). Despite higher frequency in patients compared to controls, there was no risk of association between prothrombin gene mutation and acute leukemia in adult Egyptians nor was there between combined genotypes of prothrombin gene mutation and factor V Leiden.

    strengthen and optimize the decision making skill and platform for a better sustainable society. The resilience framework provides a cross-sector and multi-level analysis to tackle the vulnerabilities which can be caused to essential utilities like power, water, transport and various machineries that are essential for human sustainability. The direction of resilience framework focuses on prevention of damage and disruption of disaster, mitigate the loss caused to human society and provide the best response for disaster resilience. Thus, the basic pillars which are important for the implementation of resilience is proper governance framework and transparency which takes into account various cost and risk analysis. Thus a common and universal framework for resilience is the main requirement for mass accessibility. The aim of resilience framework focuses on universal adaptability, coherence and validation. A mixed method analysis has been undertaken in this research paper which focuses on the following issues: • Legal, Institutional and community framework for integrating resilience framework of global north and global south. • Spatial as well as statistical analysis to structuralize disaster risk and resilient framework for disaster management. • Early warning system and emergency response in a comparative scale to analyse the various models of risk and resilience framework implemented in USA, China, Nepal and India for proposing an integrated resilience strategy.

    Achieving universal health coverage (UHC) involves distributing resources, especially human resources for health (HRH), to match population needs. This paper explores the policy lessons on HRH from four countries that have achieved sustained improvements in UHC: Brazil, Ghana, Mexico and Thailand. Its purpose is to inform global policy and financial commitments on HRH in support of UHC. The paper reports on country experiences using an analytical framework that examines effective coverage in relation to the availability, accessibility, acceptability and quality (AAAQ) of HRH. The AAAQ dimensions make it possible to perform tracing analysis on HRH policy actions since 1990 in the four countries of interest in relation to national trends in workforce numbers and population mortality rates. The findings inform key principles for evidence-based decision-making on HRH in support of UHC. First, HRH are critical to the expansion of health service coverage and the package of benefits; second, HRH strategies in each of the AAAQ dimensions collectively support achievements in effective coverage; and third, success is achieved through partnerships involving health and non-health actors. Facing the unprecedented health and development challenges that affect all countries and transforming HRH evidence into policy and practice must be at the heart of UHC and the post-2015 development agenda. It is a political imperative requiring national commitment and leadership to maximize the impact of available financial and human resources, and improve healthy life expectancy, with the recognition that improvements in health care are enabled by a health workforce that is fit for purpose.

    Human resources are an important factor in establishing universal health coverage (UHC). We examined Japan's health policies related to development of human resources for health (HRH) toward establishing UHC, and tried to formulate a model for other countries wanting to introduce UHC through reviewing existing data and documents related to Japan's history in developing HRH. In the results, there were four phases of HRH development in Japan: Phase 1 involved a shortage of HRH; Phase 2 was characterized by rapid production of less-educated HRH; Phase 3 involved introduction of quality improvement procedures such as upgrade education for nursing staff or licensing examination for physicians; Phase 4 was characterized by a predominance of formal health professionals. To encourage transition between these phrases, Japan utilized several procedures, including: (i) offering shorter professional education, (ii) fewer admission requirements for professional education, (iii) widespread location of schools, and (iv) the aforementioned quality improvement procedures. Japan was able to introduce UHC during Phase 3, and Japanese health indicators have improved gradually through these phases. Consequently, the government of Japan focused on increasing the quantity of HRH through relaxed admission requirements, shorter education periods, and increasing the numbers of educational facilities, before introducing UHC. Subsequently, the government began focusing on improving quality through procedures such as upgrade education or licensing examination programs to enable less-educated HRH to become fully educated professionals. For governments wanting to introduce UHC, the Japanese model can be a suitable option for HRH development, particularly in resource-poor countries.

    Full Text Available Introduction: Human Papilloma Virus (HPV is one of the most common causes of sexually transmitted diseases in both men and women worldwide. Aim: The investigation of the knowledge of university students and their mothers about the HPV, the ways of transmission, prevention and vaccination. Material and Method: The studied population consisted of 605 students from Technological Educational Institute of Athens and 50 mothers which filled two different questionnaires with closed-ended questions. Data was statistically processed with Microsoft Excel and SPSS ver.20. Results: Although, a large percentage (84.5% of the questioned students were sexually active, the majority of them (67.7% had never done the human papilloma virus vaccine and they didn’t intended to do it (87.9%. Although questioned mothers were aware that both girls and boys should be vaccinated against HPV infection (83.7%, only 71.4% of them had vaccinated their children, because of their fear of possible side effects (p0.05. Conclusion: Although students and mothers were aware of the HPV and its prevention, they were not familiar with the safety and the effectiveness of the vaccine, maybe because more students had been informed about the HPV from their family mostly than their gynecologist.

    Listeners of all ages and societies produce a similar consonance ordering of chromatic scale tone combinations. Despite intense interest in this perceptual phenomenon over several millennia, it has no generally accepted explanation in physical, psychological, or physiological terms. Here we show that the musical universal of consonance ordering can be understood in terms of the statistical relationship between a pattern of sound pressure at the ear and the possible generative sources of the acoustic energy pattern. Since human speech is the principal naturally occurring source of tone-evoking (i.e., periodic) sound energy for human listeners, we obtained normalized spectra from more than 100000 recorded speech segments. The probability distribution of amplitude/frequency combinations derived from these spectra predicts both the fundamental frequency ratios that define the chromatic scale intervals and the consonance ordering of chromatic scale tone combinations. We suggest that these observations reveal the statistical character of the perceptual process by which the auditory system guides biologically successful behavior in response to inherently ambiguous sound stimuli.

  19. A General Education Course in Cultural Astronomy: Exploring the Universe Through Human Eyes

    Astronomy courses for non-science majors (often referred to as Astro 101) are the bread and butter of the general education service obligation of astronomy faculty and programs across the US. Their content has traditionally been a general survey of the solar system, stars and galaxies, or even the entire universe. However, because the audience is students who will not be continuing on in astronomy, there is actually no need to cover a broad range of specific topics. Rather, it is more important to concentrate on the scientific process, and hopefully leave the student with an understanding of the relevance of science in everyday life, regardless of his or her major. As a result, some faculty prefer a more interdisciplinary focus for their Astro 101 classes, for example courses on the search for extraterrestrial life. Another option for general education astronomy courses is what has become known as cultural astronomy. Cultural astronomy focuses on the ways in which astronomical knowledge and belief influences human behavior and social structures. Under this umbrella fall two important areas of study, archaeoastronomy (concentrating on ancient cultures) and enthoastronomy (focusing on extant cultures). Such interdisciplinary courses draw heavily upon archaeology, history, anthropology, art, and other fields more traditionally aligned with the humanities and social sciences than the natural sciences, and therefore can be attractive to students in these non-science majors. In such courses, students experience the “humanity” of science: the important connections between science and the human experience, and how experts in myriad fields contribute in meaningful ways to our understanding of how astronomical knowledge has been constructed and disseminated across time and space. This poster describes the content and pedagogy of a general education course in cultural astronomy for non-science majors that stresses hands-on and experiential learning, including the use of

    The factor V Leiden (FVL) genetic test is used by many physicians despite its uncertain clinical utility. We investigate whether self-reported motivations and behaviors concerning FVL genetic testing differ between 2 groups of primary care physicians defined by frequency of previous FVL test use. In January 2007, 112 physicians (60 frequent and 52 infrequent FVL test users) at Group Health, a large health care delivery system, were surveyed. Survey content areas included primary reasons and motivating factors for ordering the FVL test, the likelihood of ordering the FVL test for hypothetical patients, potential barriers to genetic testing, and practices and skills regarding FVL test ordering. Responses between groups agreed concerning most clinical- and patient-related factors. Frequent-FVL physicians were more likely than infrequent-FVL physicians to report ordering the FVL test for hypothetical patients with mesenteric venous thrombosis (adjusted odds ratio, 4.57; 95% confidence interval, 1.55-13.53) or venous thrombosis after hospital discharge (adjusted odds ratio, 3.42; 95% confidence interval, 1.30-8.95). Frequent-FVL physicians were also less likely to identify several items on the survey as barriers to genetic testing and were more likely to report high confidence in interpreting and explaining FVL test results. Generally, both physician groups reported similar motivating factors for ordering FVL tests, and reported behaviors were consistent with existing guidelines. More striking differences were observed for measures such as barriers to and confidence in using genetic tests. Although additional research is necessary to evaluate the impact of these results, they inform several knowledge-to-practice translation issues that are important for the successful integration of genetic testing into primary care.

    The presence of Factor V Leiden (FVL) is proposed to be associated with a higher risk for arterial thrombosis. The aim of this study was to examine a relationship between FVL with the presence and severity of angiographically determined coronary artery disease (CAD). In this case-control study, 1083 patients having angiographic evidence of atherosclerosis with ≥50% luminal stenosis in their epicardial coronary tree were compared with patients with no luminal stenosis (n=320) or with luminal stenosis Factor V polymorphisms was analyzed using polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP). FVL was found to be independently associated with the occurrence of CAD (p=0.020). As compared to wild genotype, heterozygote or homozygote mutant genotypes were more likely associated with a trend towards more severe CAD (adjusted OR=1.85, 95% CI=1.26 to 2.72; p=0.002, and adjusted OR=3.70, 95% CI=1.71 to 8.00; p=0.001; respectively). In addition, the median and inter-quartile range for Gensini score were significantly different among the GG (27.8, 3 to 66.5), GA (53.5, 10 to 104.1), and AA (92.8, 48.1 to 125.9) genotypes (p<0.001). Our results confirmed the hypothesis that FVL mutation is a significant determinant of CAD risk. Furthermore, we observed that FVL is independently associated with increasing CAD severity.

    Full Text Available Physicians usually do not suspect pulmonary thromboembolism in younger patients except in those who have thrombophilia. In those latter patients some special conditions such as trauma or surgery may provoke the disease. In some adult persons, thrombophilia may still remain unrecognized, until appearance of additional conditions influence development of thrombosis. A 55-year-old Caucasian female, non-smoker, experienced sudden chest pain and hemoptysis without chest trauma. History taking revealed type 2 diabetes mellitus and hypothyroidism. She was overweight with body mass index 29.0. The review of the family history revealed that her father and mother died of brain infarction, while her 22-year-old son and 24-year-old daughter were healthy. Due to suspicion for thrombosis, multi-slice computerized tomography thorax scan was done and pulmonary embolism was diagnosed. Although without clear risk factor for thrombosis in our patient, we performed laboratory investigation for congenital thrombophilia. Genetic analysis showed double heterozygous for factor V Leiden and prothrombin 20210 G>A mutations. Congenital thrombophilia was risk factor for thrombosis in our patient but haemostatic imbalance was not previously clinically recognized. She had two pregnancies without complications. Appearance of other associative factors such as endocrine disorders - hypothyroidism and metabolic syndrome with diabetes type 2, and overweigh were additional potential triggers for clinical manifestation of pulmonary thromboembolism in her adult age. Her children underwent genetic analysis, too. The son was also double heterozygous for factor V Leiden and prothrombin 20210 G>A mutations, while daughter was heterozygous for factor V Leiden, and none had clinical signs of thrombosis.

    Factor V Leiden is the most common genetic variation among the blood coagulation pathway which leads to prothrombotic state, therefore, is considered an important gene for understating the stroke mechanism. The aim of the present study is to determine the relationship between single nucleotide polymorphism at G1691A position of Factor V gene and risk of ischemic stroke (IS) in North Indian population. In a retrospective case-control study, 250 patients with IS and 250 age- and gender-matched controls were enrolled in the period of October 2012 to September 2014 from in- and out-patient department of Neurology, All India Institute of Medical Sciences, New Delhi, India. Deoxyribonucleic acid for each case and control was isolated from peripheral blood using phenol-chloroform extraction method. Polymerase chain reaction-restriction fragment length polymorphism method was used to determine the polymorphism. Data were analyzed using STATA Software Version 13. The mean age of IS patient was 52.8 ± 12.5 years and in control group was 50.97 ± 12.7 years. Genotypic frequency distributions were in accordance with Hardy-Weinberg equilibrium in both cases and controls. As expected hypertension, diabetes, dyslipidemia, smoking, heavy alcohol intake, family history of stroke, and poor economic status were significantly associated with the risk of IS. Multivariate analysis revealed 5.17 times higher odds for developing the risk of large vessel subtype of IS in patients carrying Factor V Leiden G1691A gene variation as compared to control subjects (OR, 5.17; 95% CI, 1.32-20.3, P = 0.01). The present study suggests that Factor V Leiden G1691A polymorphism may be significantly associated with the risk of large vessel subtype of IS. Large sample size studies using prospective cohort designs are required to corroborate the present findings.

    An evaluation for heritable thrombophilias is recommended in the evaluation of stillbirth. However, the association between thrombophilias and stillbirth remains uncertain. We sought to assess the association between maternal and fetal/placental heritable thrombophilias and stillbirth in a population-based, case-control study in a geographically, racially, and ethnically diverse population. We conducted secondary analysis of data from the Stillbirth Collaborative Research Network, a population-based case-control study of stillbirth. Testing for factor V Leiden, prothrombin G20210A, methylene tetrahydrofolate reductase C677T and A1298C, and plasminogen activating inhibitor (PAI)-1 4G/5G mutations was done on maternal and fetal (or placental) DNA from singleton pregnancies. Data analyses were weighted for oversampling and other aspects of the design. Odds ratios (OR) were generated from univariate models regressing stillbirth/live birth status on each thrombophilia marker. Results were available for ≥1 marker in 488 stillbirths and 1342 live birth mothers and 405 stillbirths and 990 live birth fetuses. There was an increased odds of stillbirth for maternal homozygous factor V Leiden mutation (2/488; 0.4% vs 1/1380; 0.0046%; OR, 87.44; 95% confidence interval, 7.88-970.92). However, there were no significant differences in the odds of stillbirth for any other maternal thrombophilia, even after stratified analyses. Fetal 4G/4G PAI-1 (OR, 0.63; 95% confidence interval, 0.43-0.91) was associated with decreased odds of stillbirth. Other fetal thrombophilias were similar among groups. Most maternal and fetal thrombophilias were not associated with stillbirth. Maternal factor V Leiden was weakly associated with stillbirth, and the fetal PAI-1 4G/4G polymorphism was associated with live birth. Our data do not support routine testing for heritable thrombophilias as part of an evaluation for possible causes of stillbirth. Copyright © 2016. Published by Elsevier Inc.

    To estimate the association between the human papillomavirus (HPV) vaccine and sexual risk behaviour, as well as the participation in the Cervical Cancer Screening Program (CCSP). Cross-sectional study. School of Medicine and Health Sciences, School of Law, and School of Economics and Business (University of Oviedo). Female university students. Information was collected about contraceptive methods, sexual behaviours, HPV knowledge, and participation in the CCSP. Furthermore, proportions and odds ratio (OR) were estimated with their corresponding 95% confidence intervals (95%CI). Approximately two-thirds (67.7%) of the sample was vaccinated against HPV, and 216 women (65.3%) were sexually active. Barrier contraceptive methods were used by 67.6% during their current intimate relationships, being less frequent in non-vaccinated women (54.9% vs. 75.4% in vaccinated female students) (P=.002). The risk of having at least one sexual risk behaviour was higher in non-vaccinated women: OR2.29 (95%CI: 1.29-4.07). In addition, the probability of having a PAP test within the CCSP was higher in non-vaccinated women: OR2.18 (95%CI: 1.07-4.47). The prevalence of sexual risk behaviours in non-vaccinated women is elevated, and it is related to the lack of use of barrier contraceptive methods. The vaccination against HPV could affect sexual behaviours and the participation in the CCSP. Therefore, the information received by young people about contraceptive methods, sexually transmitted diseases, and cancer prevention should be reinforced. Copyright © 2017 Elsevier España, S.L.U.

    Factor V Leiden and prothrombin G20210A are related genetic risk factors for venous thromboembolism (VTE). Analysis for both mutations is increasingly being performed on patients exhibiting hypercoagulability. The objective of this study was to determine the prevalence of factor V Leiden (FVL), prothrombin-G20210A (PT-G20210A) polymorphisms and their coexistence among apparently healthy Jordanians. One thousand apparently healthy individuals from representative regions of Jordan with no previous history of VTE participated in this study. The mean age of participants was 28.5+/-6.4 years (age range 18-45 years). Two hundred and eighteen subjects were APC resistant with an APC-R mean of 85.52+/-15.35 seconds; the non-resistant subjects had an APC-R mean of 159.90+/-26.96 seconds. A multiplex polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) for the simultaneous detection of FVL and prothrombin G20210A was used to analyze the 218 DNA samples that were APC-R resistant. Both mutations generate HindIII RFLPs and the prothrombin amplicon contains an invariant HindIII recognition sites. The multiplex PCR-RFLP of Factor V for those 218-samples was: 41 wild-type, 169 heterozygous mutant, and eight homozygous mutant individuals. For prothrombin G20210A, the multiplex PCR-RFLP identified 215 wild-type and three heterozygous mutant individuals. Factor V positive individuals (n=50) had a mean F-V activity of 78.04%+/-25.81. F-V activity among wild type (n=41), F-V Leiden heterozygous (n=169) and F-V Leiden homozygous (n=8) were 92.93%+/-16.17, 87.02%+/-15.21 and 96.14%+/-12.32, respectively. Factor II positive subjects (n=47) had a mean factor II activity of 127.96%+/-21.37. F-II activity among carriers (heterozygous, n=3) and non-carriers (normal, n=215) of PT-G20210A mutation were 107.67%+/-9.29 and 105.00%+/-17.79, respectively. The prevalence of FVL was 21.8% and there is a little likelihood of the co-inheritance of the FVL and PT-G20210A among

    : Paget-Schroetter syndrome or effort thrombosis is characterized by spontaneous thrombosis of the upper extremity venous system, commonly seen in a young healthy patient after repetitive use of the upper extremities. It is rarely associated with coagulopathy and thus, hypercoagulable work-up is not usually a part of the investigation. We present a first case of a young woman, who was diagnosed with left upper extremity effort thrombosis following a dental procedure. Interestingly, she was also noted to be heterozygous for factor V Leiden mutation.

  10. SV-IV Peptide1–16 reduces coagulant power in normal Factor V and Factor V Leiden

    2007-12-01

    Full Text Available Abstract Native Factor V is an anticoagulant, but when activated by thrombin, Factor X or platelet proteases, it becomes a procoagulant. Due to these double properties, Factor V plays a crucial role in the regulation of coagulation/anticoagulation balance. Factor V Leiden (FVL disorder may lead to thrombophilia. Whether a reduction in the activation of Factor V or Factor V Leiden may correct the disposition to thrombophilia is unknown. Therefore we tested SV-IV Peptide 1–16 (i.e. a peptide derived by seminal protein vescicle number IV, SV-IV to assess its capacity to inhibit the procoagulant activity of normal clotting factor V or Factor V Leiden (FVL. We found that SV-IV protein has potent anti-inflammatory and immunomodulatory properties and also exerts procoagulant activity. In the present work we show that the SV-IV Peptide 1–16, incubated with plasma containing normal Factor V or FVL plasma for 5 minutes reduces the procoagulant capacity of both substances. This is an anticoagulant effect whereas SV-IV protein is a procoagulant. This activity is effective both in terms of the coagulation tests, where coagulation times are increased, and in terms of biochemical tests conducted with purified molecules, where Factor X activation is reduced. Peptide 1–16 was, in the pure molecule system, first incubated for 5 minutes with purified Factor V then it was added to the mix of phosphatidylserine, Ca2+, Factor X and its chromogenic molecule Chromozym X. We observed a more than 50% reduction in lysis of chromogenic molecule Chromozym X by Factor Xa, compared to the sample without Peptide 1–16. Such reduction in Chromozym X lysis, is explained with the reduced activation of Factor X by partial inactivation of Factor V by Peptide 1–16. Thus our study demonstrates that Peptide 1–16 reduces the coagulation capacity of Factor V and Factor V Leiden in vitro, and, in turn, causes factor X reduced activation.

Data collection comprised two phases. Phase I established face and content validity of the instrument by a panel of six experts. Phase II assessed internal consistency reliability using Cronbach's alpha and predicted behavioral intentions applying multiple linear regression. HPV knowledge, expectations, self-efficacy to get HPV vaccine, situational perception, self-efficacy in overcoming barriers to get HPV vaccine, and self-control to get HPV vaccine were regressed on behavioral intentions. Situational perception and self-control to get HPV vaccine were significant predictors, accounting for 22% of variance in behavioral intentions to get vaccinated within the next 6 months. Overall, college men reported low behavioral intentions to getting vaccinated. Future interventions should target situational perception and self-control to increase HPV vaccination intentions. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    To estimate the prevalence of Human papillomavirus (HPV) among university students and to use it as a biological marker to assess sexual behavior. A cross-sectional study was carried out between 2000 and 2001 among 194 students at Universidad Autónoma del Estado de Morelos, Mexico. A data collection instrument was applied and genital samples were taken to detect oncogenic HPV DNA. Data were analyzed using the chi-squared test and odds ratios. Overall HPV prevalence was 14.4%. Women who had had two or more sexual partners during the previous year showed a greater risk of HPV infection (OR 6.0, 95% CI 1.7-21.1), as did women who had used oral contraceptives and spermicides at their latest intercourse (OR 3.0, 95% CI 1.0-8.7). Males who consumed cocaine were at a greater risk of HPV infection (OR 7.6, 95% CI 1.3-45.1). HPV prevalence is relatively high. HPV is a reliable biological marker of sexual behavior among females. A greater sample size may be needed to assess its reliability among men.

    In 2010-2012, the North American Specialized Coagulation Laboratory Association (NASCOLA) distributed 12 proficiency testing challenges to evaluate laboratory testing for protein S (PS). Results were analysed to assess the performance of PS activity, PS free antigen, and PS total antigen testing. Statistical analysis was performed on the numeric results and qualitative classification submitted for each method. There were 2,106 total results: 716 results from PS activity assays, 833 results from PS free antigen assays, and 557 results from PS total antigen assays. The three assay types performed well in the classification of five normal samples and nine abnormal samples, although certain PS activity methods were more likely to classify normal samples as abnormal and one PS total antigen assay was more likely to classify abnormal samples as normal. PS activity methods were affected by interfering substances such as heterozygous or homozygous factor V Leiden mutation (underestimation) and the anticoagulant drug rivaroxaban (overestimation). In conclusion, NASCOLA laboratories using a variety of PS assays performed well in the classification of clearly normal and abnormal samples. Laboratories performing PS activity assays should be aware of potential interferences in samples positive for FV Leiden or containing certain anticoagulant medications.

    2016-09-01

    Background: The etiology of multifocal osteonecrosis is not definitively known; however, hypercoagulable state is a very plausible cause. Methods: We present an unusual case of a 12-year-old boy with a history of Legg-Calve-Perthes disease presenting with right wrist pain who was subsequently diagnosed with Kienbock's disease. The finding of multifocal osteonecrosis prompted testing for a hypercoagulable state that was positive for Factor V Leiden thrombophilia. A thorough literature review using Medline database was conducted to investigate associations between inherited hypercoagulable states and multifocal osteonecrosis. Results: Our literature review identified 2 similar cases of multifocal osteonecrosis associated with a hypercoagulable disorder in adult patients. There were no reports among the pediatric patient population. Meta-analysis has demonstrated a potential link between Legg-Calve-Perthes disease and Factor V Leiden thrombophilia. Conclusions: This study offers further evidence to support the theory that multifocal osteonecrosis may be linked to a hypercoagulable state. Patients presenting with multifocal osteonecrosis should undergo screening for hypercoagulable states. Further investigation is needed to ascertain the potential benefit of prophylactic anticoagulation in patients with a known hypercoagulable state and multifocal osteonecrosis.

    This paper aimed to expand the paradigm of nursing and expand the essential factors of nursing theories beyond "environment" to encompass universal life. While individuals live between the sky and earth, we are an inseparable part of the universe. "Health" is derived from a oneness that embraces the body, mind and spirit. The human body contains the wisdom of the universe, known in Chinese philosophy as the wisdom of "Changes". The body has its own consciousness and possesses great powers of self-healing. Healthiness is the original condition of life. Modern medicine assumes sickness to be a natural phenomenon, with the essential nature of "Changes" neglected as a universal law for maintaining health. Dr. Sun, a renowned physician from the Tang Dynasty, was quoted as saying "Knowing Changes is the prerequisite of knowing medicine." Another saying holds that, "Every word and every sentence in the Book of Changes is an indicator of medicine." Much emphasis has been placed on the relationship between "Changes" and "medicine" in the past. This paper elaborates the relationship between nature and human health in order to provide a clear understanding of the nature of true health, described from the perspectives of medicine and "Changes", an evaluation of modern medical science and the oneness of body-mind-spirit, which is the reality of health. The human body is thus a reflection of the mind and spirit, while the mind and spirit is the "inner body". The body is a highly intelligent organism that truly reflects our inner world. Our inner world is also displayed through physical symptoms. As human suffering is caused by separation from our inner life, the only path to enjoying a healthy and joyful life is to achieve a oneness between our body-mind-spirit. Such is a universal law, which is called "Changes" or "Oneness".

    Full Text Available Abstract Background Although access to life-saving treatment for patients infected with HIV in South Africa has improved substantially since 2004, treating all eligible patients (universal access remains elusive. As the prices of antiretroviral drugs have dropped over the past years, availability of human resources may now be the most important barrier to achieving universal access to HIV treatment in Africa. We quantify the number of HIV health workers (HHWs required to be added to the current HIV workforce to achieve universal access to HIV treatment in South Africa, under different eligibility criteria. Methods We performed a time and motion study in three HIV clinics in a rural, primary care-based HIV treatment program in KwaZulu-Natal, South Africa, to estimate the average time per patient visit for doctors, nurses, and counselors. We estimated the additional number of HHWs needed to achieve universal access to HIV treatment within one year. Results For universal access to HIV treatment for all patients with a CD4 cell count of ≤350 cells/μl, an additional 2,200 nurses, 3,800 counselors, and 300 doctors would be required, at additional annual salary cost of 929 million South African rand (ZAR, equivalent to US$ 141 million. For universal treatment (‘treatment as prevention’, an additional 6,000 nurses, 11,000 counselors, and 800 doctors would be required, at an additional annual salary cost of ZAR 2.6 billion (US$ 400 million. Conclusions Universal access to HIV treatment for patients with a CD4 cell count of ≤350 cells/μl in South Africa may be affordable, but the number of HHWs available for HIV treatment will need to be substantially increased. Treatment as prevention strategies will require considerable additional financial and human resources commitments.

This study evaluates the knowledge and attitudes towards HPV infection and vaccination, and the readiness for the uptake of HPV vaccine amongst female students attending Oakland University (OU in Michigan, United States. This is a cross-sectional study targeting a randomized sample of a 1000 female OU students using an online questionnaire. The data were statistically analyzed using SPSS software. A total of 192 female students, with the mean age of 24 years completed the survey. The majority of participants had previous sexual experience with occasional use of contraceptives (78.1%, were non-smokers (92.7%, and non-alcohol drinkers (54.2%. The participants had a mean knowledge score of 53.0% with a standard error of 2.3% translating to a moderately informed population. The majority agreed that HPV is life threatening (79%, the vaccine prevents cervical cancer (62%, and that side effects would not deter them from vaccination (63%. Although two thirds (67% believed that, based on sexual practices in the United States, female college students in Michigan have a higher chance of contracting HPV, about 50% did not believe they themselves were at risk. Higher knowledge correlated with increased recommendation for the vaccine (correlation-factor 0.20, p = 0.005. Results suggested that the best predictor for improvement of vaccination was the awareness level and health education. This indicates a need for an educational intervention to raise awareness, increase HPV vaccine uptake, and decrease the incidence of cervical cancer.

    Coagulation factor II G20210A and coagulation factor V (Leiden) G1691A single nucleotide polymorphisms (SNPs) are major inherited risk factors of venous thromboembolism. In view of the heterogeneity in their world distribution and lack of sufficient information about their distribution among Chechans, we addressed the prevalence of these SNPs in the Chechan population in Jordan, a genetically isolated population. Factor II G20210A and factor V Leiden SNPs were analysed by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) method and Amplification refractory mutation detection system (ARMS) respectively in 120 random unrelated subjects from the Chechan population in Jordan. Among the subjects studied for factor II G20210A mutation there were three individuals carrying this mutation as heterozygous (one female and two male), giving a prevalence of 2.5 % and an allele frequency of 1.25 %. No homozygous factor II allele was found. Factor V Leiden G1691A mutation was detected as heterozygous in 22 of 120 of individuals (17 female and five male) indicating a prevalence of 18.3 % and allele frequency of 9.2 %. No homozygous allele was found. Our results indicated that prevalence of factor II G20210A mutation in the Chechan population is similar to prevalence in Jordan and Caucasian populations (1-6 %) while the prevalence of factor V Leiden was higher in the Chechan population compared to Jordan and Caucasian populations (2-15 %).

    We sought to assess the benefits, risks, and personal utility of factor V Leiden mutation testing to improve pregnancy outcomes and to assess the utility of decision-analytic modeling for complex outcomes in genomics. We developed a model to evaluate factor V Leiden testing among women with a history of recurrent pregnancy loss, including heparin therapy during pregnancy in mutation-positive women. Outcomes included venous thromboembolism, major bleeds, pregnancy loss, maternal mortality, and quality-adjusted life-years. Factor V Leiden testing in a hypothetical cohort of 10,000 women led to 7 fewer venous thromboembolic events, 90 fewer pregnancy losses, and an increase of 17 major bleeding events. Small improvements in quality-adjusted life-years were largely attributable to reduced mortality but also to improvements in health-related quality of life. However, sensitivity analyses indicate large variance in results due to data uncertainty. Furthermore, the complexity of outcomes limited our ability to fully capture the repercussions of testing in the quality-adjusted life-year measure. Factor V Leiden testing involves tradeoffs between clinical and personal utility, and additional effectiveness data are needed for heparin use to prevent pregnancy loss. Decision-analytic methods offer somewhat limited value in assessing these tradeoffs, suggesting that evaluation of complex outcomes will require novel approaches to appropriately capture patient-centered outcomes.Genet Med 2013:15(5):374-381.

    While Factor V Leiden (F5 rs6025 A allele) is a known venous thromboembolism (VTE) risk factor, VTE risk among heterozygous vs. homozygous carriers is uncertain. In a retrospective cohort study of Mayo Clinic patients referred for genotyping between 1996 and 2013, we tested Factor V Leiden genotype as a risk factor for incident and recurrent VTE. Among heterozygous (n=268) and homozygous (n=111) carriers, the prevalence of VTE was 54% and 68%, respectively (p=0.016). While mean patient age at first VTE event (43.9 vs. 42.9years; p=0.70) did not differ significantly, median VTE-free survival was modestly shorter for homozygous carriers (56.8 vs 59.5 years; p=0.04). Sixty-nine (48%) and 31 (42%) heterozygous and homozygous carriers had ≥1 VTE recurrence (p=0.42). In a multivariable model, idiopathic incident VTE and a second thrombophilia were associated with increased and anticoagulation duration >6months with reduced hazards of VTE recurrence; Factor V Leiden genotype was not an independent predictor of recurrence. Aside from a higher VTE prevalence and modestly reduced VTE-free survival, VTE penetrance and phenotype severity did not differ significantly among homozygous vs. heterozygous carriers, suggesting that VTE prophylaxis and management should not differ by Factor V Leiden genotype.

    Leiden and Cambridge factor V coagulation mutations and activated protein C resistance (RaPC) are alterations related with vein and artery thrombosis. In this study we aimed to determine whether RaPC is associated with the presence of Leiden and Cambridge mutation and the frequency of these mutations in the racially mestizo Mexican population. We included 150 Mexican patients with primary thrombophilia and 100 healthy subjects in this study. RaPC was determined using commercial methods and genotypes FV Leiden and FV Cambridge with PCR-RFLPs. RaPC was positive in four patients and in one control individual; however, there was no presence of Leiden or Cambridge mutation in the studied group; thus, RaPC was not correlated with the presence of any of the studied mutations. These results indicate that there are other primary or secondary causes different from those studied, which condition the presence of RaPC. Furthermore, the frequency obtained for RaPC in our thrombophilic population of racially mixed Mexicans is lower compared to that obtained in the Caucasian population, most probably because they are genetically different populations.

    Full Text Available As tromboses são eventos de etiopatogênese multifatorial resultantes da interação de fatores genéticos e ambientais, constituindo na atualidade uma das causas mais comuns de morbimortalidade. Uma mutação de ponto no fator V da coagulação, o fator V Leiden (FVL, constitui o defeito genético mais comum associado com trombofilia. No Brasil, o estudo deste fator de risco é relativamente recente e se dispõe de poucos dados na literatura especializada. Este trabalho teve como objetivo determinar a freqüência da mutação do fator V Leiden em 292 indivíduos sob investigação de trombofilia no Hemocentro de Pernambuco. A técnica molecular utilizada foi a RE/PCR (Enzima de Restrição/Reação em Cadeia da Polimerase, usando primers específicos e a enzima MnlI. A freqüência do FVL encontrada foi de 13,3%, sendo 36 heterozigotos e 3 homozigotos. A presença da mutação foi semelhante em indivíduos com idade tanto inferior quanto superior a 45 anos. Os resultados da pesquisa mostraram que a freqüência do FVL na população estudada é semelhante à descrita na literatura científica para indivíduos selecionados com tromboembolismo e confirmam a importância do estudo molecular nas diferentes faixas etárias.Thrombosis is a multifactorial disease involving genetic and environmental factors and constitutes one of the most common causes of morbimortality.

    Despite the paradigm that carbohydrates are T cell-independent antigens, isotype-switched glycan-specific IgG antibodies and polysaccharide-specific T cells are found in humans. We employed a systems level approach combined with glycan array technology to decipher the repertoire of carbohydrate-specific IgG antibodies in intravenous and subcutaneous immunoglobulin (IVIG/SCIG) preparations. A strikingly universal architecture of this repertoire with modular organization among different donor p...

    Full Text Available BACKGROUND: Human Enterovirus 71 (EV71 is a common cause of hand, foot and mouth disease (HFMD in young children. It is often associated with severe neurological diseases and mortalities in recent outbreaks across the Asia Pacific region. Currently, there is no efficient universal antibody test available to detect EV71 infections. METHODOLOGY/PRINCIPAL FINDING: In the present study, an epitope-blocking ELISA was developed to detect specific antibodies to human EV71 viruses in human or animal sera. The assay relies on a novel monoclonal antibody (Mab 1C6 that specifically binds to capsid proteins in whole EV71 viruses without any cross reaction to any EV71 capsid protein expressed alone. The sensitivity and specificity of the epitope-blocking ELISA for EV71 was evaluated and compared to microneutralization using immunized animal sera to multiple virus genotypes of EV71 and coxsackieviruses. Further, 200 serum sample from human individuals who were potentially infected with EV71 viruses were tested in both the blocking ELISA and microneutralization. Results indicated that antibodies to EV71 were readily detected in immunized animals or human sera by the epitope blocking ELISA whereas specimens with antibodies to other enteroviruses yielded negative results. This assay is not only simpler to perform but also shows higher sensitivity and specificity as compared to microneutralization. CONCLUSION: The epitope-blocking ELISA based on a unique Mab 1C6 provided highly sensitive and 100% specific detection of antibodies to human EV71 viruses in human sera.

    Full Text Available Abstract Introduction Cytomegalovirus-associated thrombosis has rarely been reported in the medical literature, and if so, mainly in immunocompromized patients. Case presentation We report the case of a 36-year-old Caucasian woman with acute cytomegalovirus infection presenting with spontaneous splenic infarcts. Trans-esophageal echocardiography did not show any vegetations or mural thrombi. The patient was also found to be heterozygous for the Factor V Leiden mutation. Anticoagulation treatment was considered but ruled out since cytomegalovirus was the obvious trigger for thrombosis in this patient. To the best of our knowledge, this is only the third report to date of cytomegalovirus-associated splenic infarcts. Conclusion This case report serves as additional evidence for the role of cytomegalovirus in thrombosis.

    Mesenteric venous thrombosis (MVT) is a rare but life threatening form of bowel ischemia. It is implicated in 6%-9% of all cases of acute mesenteric ischemia. The proportion of patients with primary (or idiopathic) MVT varies from 0% to 49%, with a decrease in frequency secondary to more recent availability of newer investigations for hypercoagulability. The presence of factor V Leiden (FVL) and prothrombin G20210A mutations (PGM) have been well documented in these cases. However, there have been scarce case reports describing MVT in heterozygotes of both these mutations occurring simultaneously and its implications on long term management. Our case describes acute MVT in a previously asymptomatic young patient with no prior history of venous thromboembolism. The patient was found to be heterozygous for FVL and PGM and treated with lifelong anticoagulation with warfarin (goal international normalized ratio: 2-3) and avoidance of hormonal contraceptives.

    Renal vein thrombosis (RVT) is a rare but potentially serious neonatal disease. Its epidemiology and its clinical and biological expression are currently well known, but its etiological exploration, like that of venous thromboembolism, is increasingly complex. Perinatal risk factors such as prematurity, dehydration, and birth asphyxia have lost their direct accountability at the expense of their interaction with constitutional disorders of hemostasis. We report a case of RVT in a newborn who was a heterozygous carrier of both factor V Leiden and the methylene tetrahydrofolate reductase (MTHFR) gene mutation. We recall the clinical and epidemiological characteristics. A search for inborn blood coagulation disorders should be systematic in the newborn infant with venous thrombosis because of the risk of recurrence, taking into account perinatal factors and maternal thrombophilia (especially if RVT is established during the prenatal period).

    Factor V Leiden heterozygosity occurs in 3-8% of the general European and US populations. Activated protein C resistance (APC-R)--a non-molecular laboratory test--can efficiently demonstrate the presence of this mutation and can be performed on most coagulation analyzers. On the other hand, fistula or graft thrombosis is a common and costly complication in hemodialysis patients. Our aim was to establish the value of APC-R determination in hemodialysis patients by assessing the risk of access thrombosis in patients with increased APC-R. A total of 133 patients (81 men, mean age 64.5 ± 14.9 years and 52 women, mean age 63.6 ± 15 years) were selected. Participants were divided into 2 groups: those with access thrombosis (54 patients, 40.6%) and those with no access thrombosis (79 patients, 59.4%), and they were tested for the most common congenital or acquired thrombophilia risk factors. Overall, 12 patients (9%) had an increased APC-R and 10 of them had at least 1 episode of access thrombosis (83.3%). Univariate analysis to estimate crude odds ratio (OR) showed an OR of 8.8 (95% CI 1.8-41.8) times higher risk for access thrombosis in these patients. No significant differences were found after adjusting for age, hypertension, diabetes mellitus, coronary artery disease, cerebrovascular disease, peripheral arterial disease and malignancy. Sex was also a factor influencing thrombosis, presenting a higher OR for women (OR 2.2, 95% CI 1.1-4.4). This study revealed a significant association between access thrombosis and increased APC-R in hemodialysis patients. This indicates that the determination of APC-R should be considered--especially, in populations with a high prevalence of Factor V Leiden--as proper anticoagulant therapy in these patients may reduce the risk of access thrombosis. © 2015 S.

    Human herpes virus-8, a γ2-herpes virus, is the aetiological agent of Kaposi sarcoma. Recently, Kaposi's sarcoma cases have increased in Zambia. However, the diagnosis of this disease is based on morphological appearance of affected tissues using histological techniques, and the association with its causative agent, Human Herpes virus 8 is not sought. This means poor prognosis for affected patients since the causative agent is not targeted during diagnosis and KS lesions may be mistaken for other reactive and neoplastic vascular proliferations when only histological techniques are used. Therefore, this study was aimed at providing evidence of Human Herpes virus 8 infection in Kaposi's sarcoma tissues at the University Teaching Hospital in Lusaka, Zambia. One hundred and twenty suspected Kaposi's sarcoma archival formalin-fixed paraffin-wax embedded tissues stored from January 2013 to December 2014 in the Histopathology Laboratory at the University Teaching Hospital, Lusaka, Zambia were analysed using histology and Polymerase Chain Reaction targeting the ORF26 gene of Human Herpes virus 8. The predominant histological type of Kaposi's sarcoma detected was the Nodular type (60.7%) followed by the plaque type (22.6%) and patch type (16.7%). The nodular lesion was identified mostly in males (40.5%, 34/84) than females (20.2%, 17/84) (p=0.041). Human Herpes virus 8 DNA was detected in 53.6% (45/84) and mostly in the nodular KS lesions (60%, 27/84) (p=0.035). The findings in this study show that the Human Herpes virus-8 is detectable in Kaposi's sarcoma tissues, and, as previously reported in other settings, is closely associated with Kaposi's sarcoma. The study has provided important baseline data for use in the diagnosis of this disease and the identification of the virus in the tissues will aid in targeted therapy.

  12. Balancing the principles: why the universality of human rights is not the Trojan horse of moral imperialism.

    Semplici, Stefano

    2013-11-01

    The new dilemmas and responsibilities which arise in bioethics both because of the unprecedented pace of scientific development and of growing moral pluralism are more and more difficult to grapple with. At the 'global' level, the call for the universal nature at least of some fundamental moral values and principles is often being contended as a testament of arrogance, if not directly as a new kind of subtler imperialism. The human rights framework itself, which provided the basis for the most relevant international declarations and documents, is not exempt from the charge. However, the refusal of a top-down conception of the universal as a sort of product for exportation should not be confused with a relativistic landscape, where all the cows can be indifferently black or white. This contribution aims at outlining an approach, which reconciles universalism as enshrined in founding human rights declarations with respect for cultural diversity. In order to do so, two conceptual frameworks are discussed: the 'tool-kit' model and the morals/ethics difference. The example of the right to quality health care confirms the argument that striking a balance between cherishing pluralism and defending some fundamental rights and obligations does not amount to an assertion of moral imperialism.

    Cerebrovascular diseases are considered in a different way concerning their etiology with regard to arterial and venous occlusion. The role of thrombophilia in this context remains undetermined. For this reason, a case-control study was conducted including a total of 202 patients (154 females, 48 males) aged from 18 to 76 years (mean: 39.8 years) suffering either from cerebral sinus venous thrombosis (n = 101) or from arterial ischemic stroke (n = 101). Study groups were evaluated on the basis of age- and gender-matched pairs. Gene mutations of factor V-1691 (factor V Leiden) and prothrombin-20210 being considered as the most common thrombophilia markers were analyzed in this study. Factor V Leiden-mutations were found in 16.8% of patients with cerebral sinus venous thrombosis (CVT) and in 17.8% of patients with arterial ischemic stroke (AIS), which was significantly more frequent than in controls at a rate of 4.95% (ORs: 3.89 and 4.16). Prothrombin-mutations were significantly more frequent in CVT at a rate of 14.9% versus 2.97% in controls (OR: 5.70). This does not apply for AIS showing a rate of 4.95% prothrombin-mutations. Rates of factor V Leiden-mutations are not different in CVT compared with AIS. In contrast, however, prothrombin-mutations were significantly more frequent in CVT than in AIS with a rate of 14.9% versus 4.95% (OR 3.35). Furthermore, 3 cases with combined heterozygosity of factor V Leiden- and prothrombin-mutation have been identified in CVT, but not in AIS or controls. All of the above mentioned mutations were exclusively heterozygous. We conclude from these data that thrombophilia in terms of factor V Leiden genotype is a risk factor for both CVT and AIS in equal measure. In contrast, prothrombin-20210-mutations were different playing a significant role in the pathogenesis of cerebral sinus vein- thrombosis, but not in arterial ischemic stroke. Also, the combined occurrence of heterozygous prothrombin- and factor V Leiden

    Saranya eSridhar

    2016-05-01

    Full Text Available Influenza A virus (IAV remains a significant global health issue causing annual epidemics, pandemics and sporadic human infections with highly pathogenic avian or swine influenza viruses. Current inactivated and live vaccines are the mainstay of the public health response to influenza although vaccine efficacy is lower against antigenically distinct viral strains. The first pandemic of the 21st century underlined the urgent need to develop new vaccines capable of protection against a broad range of influenza strains. Such universal influenza vaccines are based on the idea of heterosubtypic immunity wherein immune responses to epitopes conserved across IAV strains can confer protection against subsequent infection and disease. T-cells recognising conserved antigens are a key contributor to reducing viral load and limiting disease severity during heterosubtypic infection in animal models. Recent studies undertaken during the 2009 H1N1 pandemic provided key insights into the role of cross-reactive T-cells in mediating heterosubtypic protection in humans. This review focuses on human influenza to discuss the epidemiological observations that underpin cross-protective immunity, the role of T-cells as key players in mediating heterosubtypic immunity including recent data from natural history cohort studies and the ongoing clinical development of T-cell inducing universal influenza vaccines. The challenges and knowledge gaps for developing vaccines to generate long-lived protective T-cell responses is discussed.

    2016-01-01

    Moral judgment in relation to animal ethics issues has rarely been investigated. Among the research that has been conducted, studies of veterinary students have shown greater use of reasoning based on universal principles for animal than human ethics issues. This study aimed to identify if this was unique to students of veterinary and other animal-related professions. The moral reasoning of first year students of veterinary medicine, veterinary technology, and production animal science was compared with that of students in non-animal related disciplines of human medicine and arts. All students (n = 531) completed a moral reasoning test, the VetDIT, with animal and human scenarios. When compared with reasoning on human ethics issues, the combined group of students evaluating animal ethics issues showed higher levels of Universal Principles reasoning, lower levels of Personal Interest reasoning and similar levels of Maintaining Norms reasoning. Arts students showed more personal interest reasoning than students in most animal-related programs on both animal and human ethics issues, and less norms-based reasoning on animal ethics issues. Medical students showed more norms-based reasoning on animal ethics issues than all of the animal-related groups. There were no differences in principled reasoning on animal ethics issues between program groups. This has implications for animal-related professions and education programs showing that students' preference for principled reasoning on animal ethics issues is not unique to animal-related disciplines, and highlighting the need to develop student (and professional) capacity to apply principled reasoning to address ethics issues in animal industries to reduce the risk of moral distress.

  7. A universal system for highly efficient cardiac differentiation of human induced pluripotent stem cells that eliminates interline variability.

    Directory of Open Access Journals (Sweden)

    Paul W Burridge

    Full Text Available BACKGROUND: The production of cardiomyocytes from human induced pluripotent stem cells (hiPSC holds great promise for patient-specific cardiotoxicity drug testing, disease modeling, and cardiac regeneration. However, existing protocols for the differentiation of hiPSC to the cardiac lineage are inefficient and highly variable. We describe a highly efficient system for differentiation of human embryonic stem cells (hESC and hiPSC to the cardiac lineage. This system eliminated the variability in cardiac differentiation capacity of a variety of human pluripotent stem cells (hPSC, including hiPSC generated from CD34(+ cord blood using non-viral, non-integrating methods. METHODOLOGY/PRINCIPAL FINDINGS: We systematically and rigorously optimized >45 experimental variables to develop a universal cardiac differentiation system that produced contracting human embryoid bodies (hEB with an improved efficiency of 94.7±2.4% in an accelerated nine days from four hESC and seven hiPSC lines tested, including hiPSC derived from neonatal CD34(+ cord blood and adult fibroblasts using non-integrating episomal plasmids. This cost-effective differentiation method employed forced aggregation hEB formation in a chemically defined medium, along with staged exposure to physiological (5% oxygen, and optimized concentrations of mesodermal morphogens BMP4 and FGF2, polyvinyl alcohol, serum, and insulin. The contracting hEB derived using these methods were composed of high percentages (64-89% of cardiac troponin I(+ cells that displayed ultrastructural properties of functional cardiomyocytes and uniform electrophysiological profiles responsive to cardioactive drugs. CONCLUSION/SIGNIFICANCE: This efficient and cost-effective universal system for cardiac differentiation of hiPSC allows a potentially unlimited production of functional cardiomyocytes suitable for application to hPSC-based drug development, cardiac disease modeling, and the future generation of clinically

    Affecting the core functional microbiome, peculiar high level taxonomic unbalances of the human intestinal microbiota have been recently associated with specific diseases, such as obesity, inflammatory bowel diseases, and intestinal inflammation. In order to specifically monitor microbiota unbalances that impact human physiology, here we develop and validate an original DNA-microarray (HTF-Microbi.Array) for the high taxonomic level fingerprint of the human intestinal microbiota. Based on the Ligase Detection Reaction-Universal Array (LDR-UA) approach, the HTF-Microbi.Array enables specific detection and approximate relative quantification of 16S rRNAs from 30 phylogenetically related groups of the human intestinal microbiota. The HTF-Microbi.Array was used in a pilot study of the faecal microbiota of eight young adults. Cluster analysis revealed the good reproducibility of the high level taxonomic microbiota fingerprint obtained for each of the subject. The HTF-Microbi.Array is a fast and sensitive tool for the high taxonomic level fingerprint of the human intestinal microbiota in terms of presence/absence of the principal groups. Moreover, analysis of the relative fluorescence intensity for each probe pair of our LDR-UA platform can provide estimation of the relative abundance of the microbial target groups within each samples. Focusing the phylogenetic resolution at division, order and cluster levels, the HTF-Microbi.Array is blind with respect to the inter-individual variability at the species level.

    The creation of large scientific collections has been an important development for anthropological and paleopathological research. Indeed the biological collections are irreplaceable reference systems for the biological reconstruction of past population. They also assume the important role of anthropological archives and, in the global description of man, permit the integration of historical data with those from bio-anthropolgical research. Thinking about the role of mummies and bones as scientific resources, best practice of preservation of ancient specimens should be of high priority for institution and researchers. By way of example, the authors mention their experience regarding ancient human remains preserved in the Museum of Anthropology and Ethnography at the University of Turin.

    2014-01-01

    Protein S is one of the major natural anticoagulants. A missense serine 501 to proline (S501P) Heerlen polymorphism is associated with reduced levels of free protein S. Heerlen polymorphism, especially when combined with other thrombophilia risk factors, can lead to thromboembolic complications. To our knowledge, we report here the first Polish case associated with heterozygous Heerlen polymorphism resulting in type III protein S deficiency, detected in a 50-year-old man with several thrombotic episodes of deep and superficial veins and a highly positive thrombotic family history. The patient also had factor V Leiden mutation and persistently elevated anticardiolipin antibodies. It seems that increased risk of thrombotic complications could be explained in the patient by a synergy between the effects of Heerlen polymorphism, factor V Leiden heterozygous status and antiphospholipid syndrome.

    Stroke in children is relatively uncommon. We describe an 8-year-old boy diagnosed with primary eosinophilic granuloma (EG) of the frontal bone. After excision of the EG, the postoperative course was eventful. The patient had an acute right middle cerebral artery (MCA) infarct and had been comatose with a diminished Glasgow Coma Scale (GCS) score of 5. Urgent decompressive hemicraniectomy with duraplasty was performed. The postoperative course after the second operation was uneventful. Hematological tests revealed a diagnosis of factor V Leiden. The patient was discharged with left hemiparesis and GCS of 15. To the best of our knowledge, no such clinical picture of MCA infarction after EG excision has been described before. Neurosurgeons should be aware of inherited thrombophilias, such as factor V Leiden, if the postoperative clinical course worsens because of cerebral artery thrombosis. Also, decompressive hemicraniectomy could be life saving and should be performed urgently without any hesitation.

    Cerebral venous thrombosis (CVT) is a rare type of stroke with a variety of causes. Several reports have suggested that either factor V Leiden or G20210A prothrombin gene mutation is associated with an increased risk of CVT. The genetic thrombophilias are typically associated with other predisposing factors. We report a unique case of CVT in a patient with both the factor V Leiden and the G20210A prothrombin gene mutations without other identifiable precipitating factors in a 28-year-old white male in good health. MRI and cerebral arterial angiography showed cerebral cortical venous thrombosis. This case suggests that combined heterozygous individuals may be particularly prone to spontaneous thrombosis, like CVT.

    The article investigates the individual agency of the little studied transnational, Bodil Begtrup, in the subfields of women's and minority rights, and refugee and asylum policy. Begtrup fulfilled many roles - as state representative, expert advisor, member of the United Nations' Commission...... the change of the institutional design of the UN human rights institutions. In the subfield of minority rights, refugee and asylum policy, Begtrup acted under tight governmental control because the issue at hand was subject to national interest and domestic party politics. Her agency in the two subfields...... on the Status of Women, and president of a national NGO. This article shows how Begtrup enjoyed wide room for manoeuvre in the subfield of women's rights, and acted in this as a transnational norm entrepreneur and process entrepreneur advocating women's rights as an integral part of human rights and forging...

    A human's ability to perform physical tasks is limited by physical strength, not by intelligence. We define "extenders" as a class of robot manipulators worn by humans to augment human mechanical strength, while the wearer's intellect remains the central control system for manipulating the extender. Our research objective is to determine the ground rules for the design and control of robotic systems worn by humans through the design, construction, and control of several prototype experimental direct-drive/non-direct-drive multi-degree-of-freedom hydraulic/electric extenders. The design of extenders is different from the design of conventional robots because the extender interfaces with the human on a physical level. Two sets of force sensors measure the forces imposed on the extender by the human and by the environment (i.e., the load). The extender's compliances in response to such contact forces were designed by selecting appropriate force compensators. This paper gives a summary of some of the selected research efforts related to Extender Technology, carried out during 1980s. The references, at the end of this article, give detailed description of the research efforts.

    Arterial and venous thrombosis are the most frequent complications in patients with polycythemia vera and essential thrombocythemia. We sought to demonstrate a possible contribution of the factor V Leiden, prothrombin G20210A, and methylenetetrahydrofolate reductase (MTHFR) 677 C > T and 1298 A > C mutations to the thrombotic risk in patients with polycythemia vera and essential thrombocythemia along with other biological features of these patients. We included 86 patients with polycythemia vera, of which 34 (39.5 %) had major thrombosis and 95 patients with essential thrombocythemia, of which 22 (23.1 %) had major thrombosis. In the whole cohort of patients, only the factor V Leiden mutation was significantly associated with both arterial and venous thrombosis in univariate and multivariate analysis (odds ratio (OR) = 4.3; 95 % confidence interval (CI) = 1.5-12.5; p = 0.008 and OR = 4.3; 95 % CI = 1.2-15.9; p = 0.02, respectively). Other factors significantly associated with thrombosis in both univariate and multivariate analysis were male sex (OR = 2.8, 95 % CI = 1.4-5.4, p = 0.002 and OR = 3.5, 95 % CI = 1.6-7.6, p = 0.002, respectively) and the JAK2 V617F mutation (OR = 5.5, 95 % CI = 2.1-15, p = 0.0001 and OR = 6.9, 95 % CI = 2.2-21.2, p = 0.001, respectively). In conclusion, among the four mutations analyzed (factor V Leiden, prothrombin G20210A, and MTHFR 677 C > T and 1298 A > C), only factor V Leiden is a major contributor to thrombosis in polycythemia vera and essential thrombocythemia.

  20. Universal power-law scaling of water diffusion in human brain defines what we see with MRI

    Veraart, Jelle; Novikov, Dmitry S

    2016-01-01

    Development of successful therapies for neurological disorders depends on our ability to diagnose and monitor the progression of underlying pathologies at the cellular level. Physics and physiology limit the resolution of human MRI to millimeters, three orders of magnitude coarser than the cell dimensions of microns. A promising way to access cellular structure is provided by diffusion-weighted MRI (dMRI), a modality which exploits the sensitivity of the MRI signal to micron-level Brownian motion of water molecules strongly hindered by cell walls. By analyzing diffusion of water molecules in human subjects, here we demonstrate that biophysical modeling has the potential to break the intrinsic MRI resolution limits. The observation of a universal power-law scaling of the dMRI signal identifies the contribution from water specifically confined inside narrow impermeable axons, validating the overarching assumption behind models of diffusion in neuronal tissue. This scaling behavior establishes dMRI as an in vivo...

    Is Universal Grammar a universal grammar? From Chomsky's hierarchy we deduce that for each grammar there is a Turing machine, and conversely. Following this equivalence, it is immediate to conclude that a universal Turing machine is equivalent to a universal grammar. Meanwhile, in linguistics, Universal Grammar is the human brain circuitry that implements the faculty of language. So the definitive answer is achieved only when we show that the human brain is Turing complete, and that language ...

    Full Text Available Might, machinations and museums. Jan van der Hoeven, Hermann Schlegel and their battle over the National Museum for Natural History in LeidenMuseums had a central place in nineteenth-century natural history. Aside from being important places for carrying out research into nature, they were also powerful vehicles for transmitting and communicating scientific knowledge. That is why, in the nineteenth century, natural history museums were frequently battlegrounds for rival scientists. Often, clashes over scientific matters were at the same time conflicts about power and space. After all, the naturalist who could get control over a museum’s collection and decide how the specimens should be classified and exhibited ultimately had the power to dictate which scientific knowledge was communicated; which story was told by a collection of specimens. This article is about the power struggle over the directorate of the National Museum of Natural History in Leiden that broke out between Jan van der Hoeven, Professor of Natural History and Comparative Anatomy at Leiden and Herman Schlegel, the museum’s chief curator. Both were rooted in very different natural historical traditions and had completely different views on the role of the museum and how the collection should be arranged and exhibited. In this article, we follow the two scientists in their attempts to gain support for their nominations. In this way, we also get a picture of nineteenth century Dutch political culture and the role scientists could play in it.

    Myocardial infarction is a multifactorial disease. It is provoked by occlusions in the coronary arteries resulting from exposure to multiple risk factors. To study the risk of myocardial infarction associated with the gene polymorphisms of factor V Leiden and factor II (G20210A). Cases consisted of 100 myocardial infarction patients who were hospitalized in the Principal Military Hospital of Tunis and 200 control subjects with no history of myocardial infarction. The prevalence of the factor V Leiden was higher in myocardial infarction patients (9%) than in control subjects (6%) with an OR=1.55 (95% CI=0.58-4.12), whereas the prevalence of prothrombin G20210A mutation was 3% and 2.5% in the patient and control groups, respectively [OR=1.21 (95% CI=0.22-5.94)]. Our results indicate that neither factor V Leiden nor the prothrombin G20210A contributed to the risk factors for myocardial infarction. Copyright © 2013 Elsevier Inc. All rights reserved.

    Epidemiological studies have reported inconsistent findings on the association between the V Leiden G1691A mutation and sudden sensorineural hearing loss (SSNHL) in Italian population. The aim of this meta-analysis was to clarify this association. PubMed, Embase, and the China National Knowledge Infrastructure (CNKI) were searched up to April 1, 2015. We used STATA12.0 to calculate summary odds ratios (ORs) with 95 % confidence intervals (CIs). Four studies including 958 patients were identified. Pooled data showed no significant association between V Leiden G1691A mutation and risk of SSNHL in Italian population: A vs. G (OR = 1.660, 95 % CI 0.428-6.446, P OR = 0.464) and AG vs. GG (OR = 1.680, 95 % CI 0.422-6.688, P OR = 0.462). The present meta-analysis suggests that V Leiden G1691A mutation is not significantly associated with increased risk of SSNHL disease in Italian population. Further large and well-designed studies are needed to confirm this association.

  5. Deepest Infrared View of the Universe

    Science.gov (United States)

    2002-12-01

    VLT Images Progenitors of Today's Large Galaxies Summary An international team of astronomers [2] has made the deepest-ever near-infrared Ks-band image of the sky, using the ISAAC multi-mode instrument on the 8.2-m VLT ANTU telescope. For this, the VLT was pointed for more than 100 hours under optimal observing conditions at the Hubble Deep Field South (HDF-S) and obtained images in three near-infrared filters. The resulting images reveal extremely distant galaxies, which appear at infrared wavelengths, but are barely detected in the deepest optical images acquired with the Hubble Space Telescope (HST). Astronomer Marijn Franx from the University of Leiden and leader of the team concludes: "These results demonstrate that very deep observations in the near-infrared are essential to obtain a proper census of the earliest phases of the universe. The new VLT images have opened a new research domain which has not been observationally accessible before". The HDF-S is a tiny field on the sky in the southern constellation Tucana (The Toucan) - only about 1% of the area of the full moon. The NASA/ESA Hubble Space Telescope (HST) observed it with a total exposure time of about 1 week, yielding the deepest optical images ever taken of the sky, similar to those made earlier on the Hubble Deep Field North (HDF-N). The VLT infrared images of the same field were obtained in the course of a major research project, the Faint InfraRed Extragalactic Survey (FIRES). They were made at wavelengths up to 2.3 µm where the HST is not competitive. Ivo Labbé, another team member from the University of Leiden, is certain: "Without the unique capabilities of the VLT and ISAAC we would never have been able to observe these very remote galaxies. In fact, the image in the Ks-band is the deepest which has ever been made at that wavelength". The optical light emitted by the distant galaxies has been redshifted to the near-infrared spectral region [3]. Indeed, some of the galaxies found in the new

    This article reviews the research at the Department of Human Biology at the Christian-Albrechts-University in Kiel since 2006. The research focuses on the investigation of recent human populations with respect to aging, chronobiology, and adaptation to high altitude. The research areas are outlined presenting findings, ongoing projects and future directions. Aging research examines biological changes in humans considering that aging is a multidimensional process. Changes in body composition, resting energy metabolism, oxidative stress, and sleep have been examined. The applicability of specific research methods to older people has been tested. Chronobiological research concentrates on investigating circadian rhythms of humans. The emphasis lies on the sleep-wake rhythm, body temperature rhythms, hormonal rhythms (cortisol and melatonin) and the circadian expression of so-called clock genes which are involved in the generation of circadian rhythms. Association studies examine the relationship between defined chronobiological phenotypes and clock gene polymorphisms. Genetic aspects are as well investigated within the third research area on the adaptation of native populations to life at high altitude in the South American Andes. Both candidate gene analysis and epigenetic parameters are investigated. Future research will concentrate on the aging of the circadian system.

    Full Text Available Modern urban performance depends not only on the city's endorsement of hard infrastructure (physical capital, but also on the availability and quality of knowledge communication and social infrastructure (intellectual capital and social capital. This is one of the clear reasons why the concept of Smart Cities recently attracted a great amount of attention, both from academia and city planners. One of the challenges of the Smart City concept is how to raise human capital among people, such as making them culturally sensitive, mobile and to improve other social characteristics. This challenge is especially valid for industrial cities that are facing economic turbulence and a demand for revitalizing their public spaces and economic specialties. The aim of this study is to examine the correlation between the amount of international students in Russian universities with the positive changes that occur in a Russian student’s human capital, and their neighbourhood areas, especially in public spaces. We aim to support the hypothesis that a network of “internationalized” universities serves as a revitalization measure for a city, facilitating the development of its surrounding areas, and reducing political and social risks within a society. Research methods for gathering data are: deductive trend search, which uses a literature review from leading academic journals and the empirical study based on the created questionnaire. This questionnaire forms a dataset which consists of a number of master courses held in English from one of the leading Russian universities based in Moscow. In this paper, we explain the research design and the results of a long-term project which we expect to complete in Russia in 2016.

    To analyse sexual behaviour, HIV testing, HIV testing intentions and reasons for not testing for HIV in university students from Cuzco (Peru). The sample comprised 1,377 university students from several institutions from Cuzco (Peru). The size of the sample was set according to a maximum 3% error estimation and a 97% confidence interval. Ages ranged from 16 to 30 years old. The data were collected through a self-administered, anonymous and voluntary questionnaire regarding sexual behaviour and HIV testing. The data were collected in classrooms during teaching hours. A higher percentage of males than females reported having had vaginal, anal and oral sex, a higher number of sexual partners and an earlier age at first vaginal and oral sex. A higher percentage of females than males did not use condoms when they first had anal sex and had a higher anal sex-risk index. Most of the participants had never been HIV tested. The main reason was that they were sure that they were not HIV infected. It seems that there was a low HIV risk perception in these participants despite the fact that they had been involved in sexual risk behaviours. Prevention campaigns focused on the general population as well as the at-risk populations and young people are needed. Copyright © 2017 SESPAS. Publicado por Elsevier España, S.L.U.

  6. A universal ankle-foot prosthesis emulator for human locomotion experiments.

    2014-03-01

    Robotic prostheses have the potential to significantly improve mobility for people with lower-limb amputation. Humans exhibit complex responses to mechanical interactions with these devices, however, and computational models are not yet able to predict such responses meaningfully. Experiments therefore play a critical role in development, but have been limited by the use of product-like prototypes, each requiring years of development and specialized for a narrow range of functions. Here we describe a robotic ankle-foot prosthesis system that enables rapid exploration of a wide range of dynamical behaviors in experiments with human subjects. This emulator comprises powerful off-board motor and control hardware, a flexible Bowden cable tether, and a lightweight instrumented prosthesis, resulting in a combination of low mass worn by the human (0.96 kg) and high mechatronic performance compared to prior platforms. Benchtop tests demonstrated closed-loop torque bandwidth of 17 Hz, peak torque of 175 Nm, and peak power of 1.0 kW. Tests with an anthropomorphic pendulum "leg" demonstrated low interference from the tether, less than 1 Nm about the hip. This combination of low worn mass, high bandwidth, high torque, and unrestricted movement makes the platform exceptionally versatile. To demonstrate suitability for human experiments, we performed preliminary tests in which a subject with unilateral transtibial amputation walked on a treadmill at 1.25 ms-1 while the prosthesis behaved in various ways. These tests revealed low torque tracking error (RMS error of 2.8 Nm) and the capacity to systematically vary work production or absorption across a broad range (from -5 to 21 J per step). These results support the use of robotic emulators during early stage assessment of proposed device functionalities and for scientific study of fundamental aspects of human-robot interaction. The design of simple, alternate end-effectors would enable studies at other joints or with

    Full Text Available Abstract Background Investigations into both the pathophysiology and therapeutic targets in muscle dystrophies have been hampered by the limited proliferative capacity of human myoblasts. Isolation of reliable and stable immortalized cell lines from patient biopsies is a powerful tool for investigating pathological mechanisms, including those associated with muscle aging, and for developing innovative gene-based, cell-based or pharmacological biotherapies. Methods Using transduction with both telomerase-expressing and cyclin-dependent kinase 4-expressing vectors, we were able to generate a battery of immortalized human muscle stem-cell lines from patients with various neuromuscular disorders. Results The immortalized human cell lines from patients with Duchenne muscular dystrophy, facioscapulohumeral muscular dystrophy, oculopharyngeal muscular dystrophy, congenital muscular dystrophy, and limb-girdle muscular dystrophy type 2B had greatly increased proliferative capacity, and maintained their potential to differentiate both in vitro and in vivo after transplantation into regenerating muscle of immunodeficient mice. Conclusions Dystrophic cellular models are required as a supplement to animal models to assess cellular mechanisms, such as signaling defects, or to perform high-throughput screening for therapeutic molecules. These investigations have been conducted for many years on cells derived from animals, and would greatly benefit from having human cell models with prolonged proliferative capacity. Furthermore, the possibility to assess in vivo the regenerative capacity of these cells extends their potential use. The innovative cellular tools derived from several different neuromuscular diseases as described in this report will allow investigation of the pathophysiology of these disorders and assessment of new therapeutic strategies.

    Objectives: Inherited thrombophilia might lead to recurrent pregnancy loss (RPL). The aim of the study was to estimate the prevalence of V coagulation factor polymorphisms related with inherited thrombophilia among women in Malopolska region.Material and methods: Group of 136 women, who experienced at least 2 unexplained, idiopathic pregnancy loss. 106 healthy women having at least one uncomplicated pregnancy and delivered healthy children constituted a control group. Each patient were examined for factor V Leiden (FVL) and mutation 1328 T>C of factor V gene with use of real –time PCR and Taq-Man probes.Results: Among patients with RPL inhabiting region of Malopolska compared to control group occurred higher prevalence of FVL and mutation 1328 T>C. There is coincidence of polymorphism 1328 T>C of factor V gene and FVL in group of early and late RPL.Conclusions: TC genotype of 1328 T>C mutation carriers reveal tendency toward RPL below 7 weeks of pregnancy.Based on results of these findings inherited thrombophilia evaluation in patients after two or more RPL should be recommended.

    Factor V Leiden (FVL) is by far the most prevalent inherited thrombophilic abnormality in Western countries, and this genetic condition has been associated with sudden sensorineural hearing loss (SSHL). Audiologists should be aware that SSHL may be the precursor of life-threatening thromboembolic events, especially in Caucasians who are more likely to be FVL carriers. Case report. A 41-year-old male patient. Although this is not the first report of SSHL in a FVL carrier, it is the first to describe SSHL occurring in a heterozygous FVL carrier who--within a month--was also diagnosed with deep vein thrombosis of the left common femoral, saphenous, and popliteal veins, and pulmonary embolism of the left pulmonary artery branch serving the posterior basal segment of the inferior lobe. SSHL is an emergency condition that warrants prompt medical examination and treatment. Hematological investigations should be considered in SSHL patients at least for those with a family history of thrombotic events, and for women on estrogen-progestin therapy or during pregnancy, with a view to providing adequate antithrombotic prophylaxis and reducing the risk of other thromboembolic events.

    Full Text Available Background: Activated protein C (APC inactivates factor V (FV by cleavage of its heavy chain at Arg306, Arg506, Arg679, and Lys994. Mutational changes, which abolish APC cleavage sites, may predispose thrombosis by altering the inactivation process of FV. FV Leiden (FVL (Arg506Glu has been demonstrated as a strong risk factor for thrombosis. In the current study, we have studied whether mutations in the cleavage sites of FV for APC, not due to FVL, would have a role in presenting APC resistance (APCR and initiation of a cerebral thrombotic event.Methods: A group of 22 patients with a history of cerebral venous thrombosis (CVT, who were not carriers of FVL enrolled in the study. The patients who had conditions associated with acquired APCR were excluded from the study. APCR test was performed on the remaining 16 patients, which showed APCR in 4 plasma samples. DNA sequencing was performed on four exons of FV of APCR patients, encoding Arg306, Arg506, Arg679, and Lys994.Results: Mutations were not found within nucleotides encoding the cleavage sites; neither was found within their close upstream and downstream sequences.Conclusion: Our results show that polymorphisms affecting cleavage sites of FV other than Arg506Glu it would be less likely to be the basis for APCR and its increased thrombosis susceptibility. In addition, it emphasizes on the importance of screening for APCR in the patients diagnosed with CVT.

    Thrombophilia due to activated protein C resistance (Leiden mutation) is the most common inherited thrombophilic disorder with 5% incidence in whites. Renal transplant of these patients entails a risk of vascular thrombosis soon after the transplant; and acute rejection episodes and graft loss within the first year. We present a case of a successful living-related renal transplant in man with a recent history of repeat episodes of vascular access thrombosis attributed to inherited thrombophilia (heterozygosity for factor V mutation Q506 and homozygosity for mutation T677 for methylene-tetrahydrofolate reductase). Transplant recipient was administered anticoagulation therapy with low molecular weight heparin pre- and postoperatively. No thrombotic or hemorrhagic events occurred posttransplant. A high suspicion of thrombophilic disorders in patients with end-stage renal disease with vascular access thrombotic events should be screened further to prevent failure of a subsequent renal transplant. Inherited thrombophilic disorders may not exclude living-related kidney transplant provided that anticoagulation therapy is admin-istered perioperatively.

    The present case study is an analysis of the effect of compression socks on hemostatic activation following a marathon in a female endurance athlete found to be heterozygous for the coagulation factor V (F5 1691 G>A [Arg>Gln rs6025/560]) risk allele that predisposes one to a genetically inherited disorder of blood clotting, Factor V Leiden. Markers for coagulation and fibrinolysis were obtained 24 h prior to (PRE), immediately after (FINISH) and 24 h after (POST) completion of two marathons: the first in which the runner was not wearing compression socks, and the second in which the runner wore compression socks throughout the race. Compression socks worn during a marathon appeared to lower the overall impact on hemostasis as well as clot formation in this particular athlete as evidenced by lower t-PA (-56%), TAT (-63%) and D-dimer (-30%). Hemostatic activation may be lower with the use of compression socks, and thus may be effective for preserving hemostasis in endurance athletes at risk.

    To investigate whether low systolic blood pressure is predictive for increased mortality risk in 90-year-old subjects without heart failure, defined by low levels of NT-proBNP, as well as in 90-year-old subjects with high levels of NT-proBNP. This study was embedded in the Leiden 85-plus Study, an observational population-based prospective study. All 90-year-old participants (n = 267) were included between 2002 and 2004 and followed up for mortality for at least 5 years. Differences in mortality risks were compared between participants with low systolic blood pressure (≤150 mmHg) and high systolic blood pressure (>150 mmHg) within strata of low NT-proBNP (low NT-proBNP, low systolic blood pressure gave a two-fold increased risk (hazard ratio 2.0, 95% confidence interval 1.1-3.4) compared with participants with high systolic blood pressure. For participants with high NT-proBNP, low systolic blood pressure provided a 1.7 increased mortality risk (95% confidence interval 1.2-2.3) compared with high systolic blood pressure. Low systolic blood pressure is predictive for increased mortality risk in 90-year-old subjects, irrespective of the NT-proBNP level. Therefore, the absence or presence of heart failure as determined by NT-proBNP does not influence the prognostic value of low systolic blood pressure with regard to mortality in the oldest old.

    2015-01-01

    Twenty five years have passed since the first research efforts in Greece on human papillomavirus (HPV) performed by the Department of Clinical Virology at the University of Crete School of Medicine. HPV infection in the human cervix was initially evaluated in relation to the host mutational and transcriptional activation of the ras/raf genes pathway, p53 gene polymorphisms, neo-angiogenesis- related gene expression and G1/S phase transition. A series of epidemiological studies ensued, evaluating HPV infection in the ophthalmic pterygium, benign laryngeal tumors, parotid lesions, nasal polyposis, actinic keratosis, aborted material and non-genital cancers. The observed geographical variations of different HPV types within the Hellenic population indicated a higher prevalence of HPV 18 on the island of Crete compared to mainland Greece. Moreover, our research led to the investigation of the mother-to-infant HPV transmission via human breast milk and the detection of novel HPV types in juvenile recurrent respiratory papillomatosis. We also evaluated the presence of HPV in the respiratory tract of asymptomatic children and the relationship between maternal HPV infection and neonatal prematurity. Despite the introduction of the current prophylactic vaccines against HPV into clinical practice, HPV remains a challenging target for the next generation of researchers, as the war against HPV continues.

  17. The Evolving Ecological Universe: a Study in the Science and Human Implications of a New World Hypothesis

    1992-01-01

    This study describes a broad cultural shift and a parallel scientific shift. Scientifically and culturally, Western civilization is moving toward a vision of a living, evolving, ecological universe and away from the Newtonian clockwork-machine universe. In Stephen Pepper's (1946) terms, the shift represents a change in dominant world hypothesis--that is, the dominant metaphor of how the world works. The bulk of the dissertation is a detailed exploration of the scientific shift because science's understanding of how the world works profoundly shapes beliefs in general. The exploration shows how a number of minirevolutions in physics and biology are related and how each supports an evolving ecological vision. The work in these different fields combines to produce a particularly important change in understanding--a vision of evolution as a single overall physical process from molecules to humankind. Ecological science (physics to biology) and the new view of evolution become possible because of a major conceptual shift in physics, the nonlinear revolution. The nonlinear revolution includes three major elements: chaos (modern nonlinear dynamics); self-organization theory (far -from-equilibrium thermodynamics); and the thermodynamics of evolution. Together these elements produce a physical understanding of an evolving, order-producing, universe --that is, a universe that evolves toward higher and higher levels of ordered complexity through interactive ecological dynamics. This very different physical picture of how the world works has important implications for human beliefs in general. A final section of the study explores the ecological shift's implications for humankind. It looks at ecological changes occurring outside the physical sciences (for example, in economics) and at how the radically changed physical sense of how the world works might affect other beliefs. For instance, the new physical view shows a remarkable ability to support and connect many

    Full Text Available Neoliberalism has dominated the world for over three decades and now permeates our laws, policies and practices at the international, national and local levels. The International Monetary Fund, the World Trade Organization, the European Union, the United States and China all support trade liberalization, privatization of public services and the primacy of markets over people. Indeed, neoliberalism has become so ingrained that it has become invisible and many of us no longer notice when new agendas conflict with international human rights laws and principles to which almost all countries in the world have committed themselves. Adopted in 1948, immediately after World War II, to implement one of the four goals of the new United Nations Organization, the norms and aspirations elaborated in the UDHR provide a framework for a radically different world than the one we have today. In this article, we revisit the content of the UDHR, beginning with the right to a social and international order in which everyone’s rights can be realized, and consider other key provisions that conflict with neoliberalism, including the rights to the benefits of science, to full employment and decent work, to progressive realization of free higher education, to nondiscrimination on the grounds of economic status and to solidarity. We also share some activities that we use in the classroom and online to make the transformative agenda of the UDHR visible to students and demonstrate how far we have strayed from the aspiration of a world in which everyone enjoys their human rights.  The article concludes that teaching a holistic vision of the UDHR in a neoliberal world is a radical human rights curriculum.

  19. Analysis of first prototype universal intelligence tests: evaluating and comparing AI algorithms and humans

    2011-01-01

    Today, available methods that assess AI systems are focused on using empirical techniques to measure the performance of algorithms in some specific tasks (e.g., playing chess, solving mazes or land a helicopter). However, these methods are not appropriate if we want to evaluate the general intelligence of AI and, even less, if we compare it with human intelligence. The ANYNT project has designed a new method of evaluation that tries to assess AI systems using well known computational notions and problems which are as general as possible. This new method serves to assess general intelligence (which allows us to learn how to solve any new kind of problem we face) and not only to evaluate performance on a set of specific tasks. This method not only focuses on measuring the intelligence of algorithms, but also to assess any intelligent system (human beings, animals, AI, aliens?,...), and letting us to place their results on the same scale and, therefore, to be able to compare them. This new approach will allow us...

  20. Effect of Brain Drain (Human Capital Flight of Librarians on Service Delivery in Some Selected Nigerian Universities

    2014-06-01

    Full Text Available This study seeks to describe and analyze the challenges occasioned by brain drain or human capital flight of librarians on service delivery in Nigerian Universities. The research adopted a descriptive survey design. A purposive sampling technique was used to select two geopolitical zones (South-South and South-West from the six geopolitical zones of Nigeria. Total enumeration was used because the population under study was considered appropriate for the research. The instrument used for data collection was questionnaire. Sixty copies of the instrument were distributed to 60 librarians in the two selected geopolitical zones. Copies of all the questionnaires were completed, retrieved, and found usable, thus giving a response rate of 100%. Survey results indicated that 315 librarians emigrated to foreign lands for various reasons, including unstable academic calendar and prospects for further training among others. This loss of personnel in the university libraries has a negative impact on service delivery as qualified information professionals and Information and Communication Technology (ICT experts are limited to mentor the younger professionals. Shift duties in academic libraries are also scaled down for lack of manpower. Based on the findings, the researchers recommend that the Federal Government of Nigeria should, as a matter of urgency, robustly fund tertiary education to enhance productivity. As they do this, the National Universities Commission (NUC is to empower academic libraries by ensuring that the staff development policy is strictly adhered to. This will translate into self-enhancement for staff, positive job attitude, and retention of professionals in the system.

    This study sought to determine knowledge of and attitude towards human papillomavirus (HPV) infection, HPV-related diseases and HPV vaccines among female undergraduate students at the University of Lagos. A self-administered questionnaire was administered between May and July 2010, to 368 female students aged 16-29years, who were selected from two faculties of the University of Lagos using two-stage sampling method. Data collected included: socio-demographic characteristics, sexual history, awareness and knowledge of HPV infection, cervical cancer and genital warts, and HPV vaccine; the perceived risk of acquiring genital HPV infection and developing cervical cancer or genital warts, and the willingness to receive an HPV vaccine. Only 64 (17.7%) and 52 (14.4%) of the students had ever heard of HPV infection and HPV vaccines respectively. The median HPV knowledge on a 15-item score was 2. Overall, only 11.1% knew that genital HPV infection can cause cervical cancer. Fourteen (6.9%) of those who were aware of cervical cancer agreed they were at risk of developing the disease. Of the 52 students who had heard of the HPV vaccine, 24 (46.2%) knew it was given for cervical cancer prevention and 30 (57.7%) expressed their willingness to receive the vaccine. The knowledge of and the perceived susceptibility to HPV infection and HPV-related diseases among female students in the University of Lagos were generally low. The need for a well-designed HPV-educational program to bridge the knowledge gap cannot be overemphasized. Copyright © 2012 Ministry of Health, Saudi Arabia. Published by Elsevier Ltd.

    2014-05-01

    Full Text Available This article demonstrates how Universal and Human-Centered Design approaches can be applied to the process of library video tutorial creation in order to enhance accessibility. A series of questions that creators should consider in order to focus their design process is discussed. These questions break down various physical and cognitive limitations that users encounter, providing a framework for future video creation that is not dependent on specific software. By approaching accommodations more holistically, videos are created with accessibility in mind from their conception. Working toward the ideal of a video tutorial that is accessible to every user leads to the creation of more clearly worded, effective learning objects that are much more inclusive, making instructional concepts available to users of all abilities.

    This study examined whether universality of the 5-factor model (FFM) of personality operationalized by the Revised NEO Personality Inventory is due to genetic influences that are invariant across diverse nations. Factor analyses were conducted on matrices of phenotypic, genetic, and environmental correlations estimated in a sample of 1,209 monozygotic and 701 dizygotic twin pairs from Canada, Germany, and Japan. Five genetic and environmental factors were extracted for each sample. High congruence coefficients were observed when phenotypic, genetic, and environmental factors were compared in each sample as well as when each factor was compared across samples. These results suggest that the FFM has a solid biological basis and may represent a common heritage of the human species.

    2017-03-07

    The aim of this study was to evaluate ex vivo and in vitro interference of a direct factor IIa inhibitor, dabigatran, on a prothrombinase-based assay to detect activated protein C resistance. An ex vivo study was performed in six heterozygous factor V Leiden carriers and 12 normal subjects without the factor V Leiden mutation who were treated with dabigatran. An in vitro study was also performed considering 12 plasma samples (six from normal subjects and six from heterozygous factor V Leiden carriers) spiked with dabigatran. The dabigatran concentration was evaluated using a diluted thrombin time assay, activated protein C resistance was evaluated using a prothrombinase-based assay. In both the ex vivo and in vitro studies dabigatran interfered significantly with activated protein C resistance ratios observed in normal subjects and in factor V Leiden heterozygous carriers. The results reported in this paper seem to confirm that dabigatran is able to interfere with the Penthafarm prothrombinase-based assay used to study activated protein C resistance, significantly increasing observed ratios. This effect appears to be present already at low concentrations of dabigatran (6 ng/mL) and affects both normal subjects and heterozygous carriers of factor V Leiden. In this group of patients, dabigatran, at concentrations in the therapeutic range (100-200 ng/mL), could markedly increase the activated protein C resistance ratio, bringing it up to within the reference range for normal subjects, thus potentially leading to misclassification of patients.

  6. A human multi-epitope recombinant vaccinia virus as a universal T cell vaccine candidate against influenza virus.

    Directory of Open Access Journals (Sweden)

    Alan G Goodman

    Full Text Available There is a need to develop a universal vaccine against influenza virus infection to avoid developing new formulations of a seasonal vaccine each year. Many of the vaccine strategies for a universal vaccine target strain-conserved influenza virus proteins, such as the matrix, polymerase, and nucleoproteins, rather than the surface hemagglutinin and neuraminidase proteins. In addition, non-disease-causing viral vectors are a popular choice as a delivery system for the influenza virus antigens. As a proof-of-concept, we have designed a novel influenza virus immunogen based on the NP backbone containing human T cell epitopes for M1, NS1, NP, PB1 and PA proteins (referred as NPmix as well as a construct containing the conserved regions of influenza virus neuraminidase (N-terminal and hemagglutinin (C-terminal (referred as NA-HA. DNA vectors and vaccinia virus recombinants expressing NPmix (WR-NP or both NPmix plus NA-HA (WR-flu in the cytosol were tested in a heterologous DNA-prime/vaccinia virus-boost vaccine regimen in mice. We observed an increase in the number of influenza virus-specific IFNγ-secreting splenocytes, composed of populations marked by CD4(+ and CD8(+ T cells producing IFNγ or TNFα. Upon challenge with influenza virus, the vaccinated mice exhibited decreased viral load in the lungs and a delay in mortality. These findings suggest that DNA prime/poxvirus boost with human multi-epitope recombinant influenza virus proteins is a valid approach for a general T-cell vaccine to protect against influenza virus infection.

Already the Laboratory of Human Anatomy of University de Caxias do Sul (AL-UCS uses more than 10,000 liters for preserving corpses in tanks. The present study aims to analyze the chemical waste management of the GH and the AL-UCS and propose techniques for recovery and reuse of chemicals formaldehyde, glutaraldehyde and xylenes, minimizing the impacts generated by the use, often indispensable and sometimes questionable, of such waste. So far two sets of samples were collected (in March and April 2013 of xylene, glutaraldehyde and formaldehyde in the GH and also at the AL-UCS and it is intended to repeat the collections with monthly periodicity, in the next two semesters. Partial results show that, comparing the relationship of area and the medium areas of the chromatographic (in µV.s of patterns with compounds of interest, an increase in the percentage of formaldehyde relative to the samples in standard formalin (121.84% may be due to contamination with organic compounds with a retention time close to the compound of interest, the xylene was little degradation in the samples, indicating that this compound can be reused in the common procedures of healthcare institutions, with respect to glutaraldehyde significant degradation was observed for the compound in samples represents only 61.88% of the chromatographic peak area of the standard, therefore the reuse of these compounds may require the use of purification methods such as simple distillation and fractional distillation

    2011-03-01

    Zoonotic infections have emerged as a burden for millions of people in recent years, owing to re-emerging or novel pathogens often causing outbreaks in the developing world in the presence of inadequate public health infrastructure. Among zoonotic infections, those caused by parasitic pathogens are the ones that affect millions of humans worldwide, who are also at risk of developing chronic disease. The present review discusses the global effect of protozoan pathogens such as Leishmania sp., Trypanosoma sp., and Toxoplasma sp., as well as helminthic pathogens such as Echinococcus sp., Fasciola sp., and Trichinella sp. The zoonotic aspects of agents that are not essentially zoonotic are also discussed. The review further focuses on the zoonotic dynamics of fungal pathogens and prion diseases as observed in recent years, in an evolving environment in which novel patient target groups have developed for agents that were previously considered to be obscure or of minimal significance.

    The definitive diagnosis of brucellosis requires isolation of the agent, although negative isolation does not rule out the infection. In contrast, serological testing is more sensitive and, therefore, preferred in clinical practice. The majority of reported cases around the world were caused by Brucella melitensis, B. abortus, B. suis and B. canis. The first three species contain O-polysaccharide (OPS) on the cell surface, but B. canis contains no measurable OPS on the rough lipopolysaccharide (R-LPS). A universal indirect enzyme immunoassay for the detection of serum antibody to smooth and rough Brucella spp. in both normal (u-IELISA®) and rapid forms (R-u-IELISA®) has been developed, and, therefore, the potential use of this method was assessed in comparison to cELISA, conventional tests, IELISA and RSAT on a total of 478 sera. The 77 sera from blood donors with no clinical or epidemiological evidence of brucellosis and negative serological tests showed a specificity of 100 % for both u-IELISA® and R-u-IELISA®, with a cut-off value of %P 24 and %P 18, respectively. Sera from 49 culture-positive cases (16 B. suis, 15 B. abortus, 12 B. melitensis and 6 B. canis) yielded a sensitivity of 98 % for u-IELISA® and 95.9 % for R-u-IELISA®. In general, u-IELISA® showed good correlation with cELISA and IELISA for the detection of antibodies to smooth and rough Brucella strains, as well as for monitoring patients during treatment, but R-u-IELISA® seems to need additional optimisation. u-IELISA® is simple to perform and could be a suitable test for field laboratories and hospitals lacking skilled personnel.

    Full Text Available Sensitive and specific detection of human papillomaviruses (HPV in cervical samples is a useful tool for the early diagnosis of epithelial neoplasia and anogenital lesions. Recent studies support the feasibility of HPV DNA testing instead of cytology (Pap smear as a primary test in population screening for cervical cancer. This is likely to be an option in the near future in many countries, and it would increase the efficiency of screening for cervical abnormalities. We present here a microarray test for the detection and typing of 15 most important high-risk HPV types and two low risk types. The method is based on type specific multiplex PCR amplification of the L1 viral genomic region followed by ligation detection reaction where two specific ssDNA probes, one containing a fluorescent label and the other a flanking ZipCode sequence, are joined by enzymatic ligation in the presence of the correct HPV PCR product. Human beta-globin is amplified in the same reaction to control for sample quality and adequacy. The genotyping capacity of our approach was evaluated against Linear Array test using cervical samples collected in transport medium. Altogether 14 out of 15 valid samples (93% gave concordant results between our test and Linear Array. One sample was HPV56 positive in our test and high-risk positive in Hybrid Capture 2 but remained negative in Linear Array. The preliminary results suggest that our test has accurate multiple HPV genotyping capability with the additional advantages of generic detection format, and potential for high-throughput screening.

    Mounting evidence shows that localized sources maintain atrial fibrillation (AF). However, it is unclear in unselected "real-world" patients if sources drive persistent atrial fibrillation (PeAF), long-standing persistent atrial fibrillation (LPeAF), or paroxysmal atrial fibrillation (PAF); if right atrial sites are important; and what the long-term success of source ablation is. The aim of this study was to analyze the role of rotors and focal sources in a large academic registry of consecutive patients undergoing source mapping for AF. One hundred seventy consecutive patients (mean age 59 ± 12 years, 79% men) with PAF (37%), PeAF (31%), or LPeAF (32%). Of these, 73 (43%) had undergone at least 1 prior ablation attempt (mean 1.9 ± 0.8; range: 1 to 4). Focal impulse and rotor modulation (FIRM) with an endocardial basket catheter was used in all cases. FIRM analysis revealed sources in the right atrium in 85% of patients (1.8 ± 1.3) and in the left atrium in 90% of patients (2.0 ± 1.3). FIRM ablation terminated AF to sinus rhythm or atrial flutter or tachycardia in 59% (PAF), 37% (PeAF), and 19% (LPeAF) of patients, with 15 of 67 terminations due to right atrial ablation. On follow-up, freedom from AF after a single FIRM procedure for the entire series was 95% (PAF), 83% (PeAF), and 82% (LPeAF) at 1 year and freedom from all atrial arrhythmias was 77% (PAF), 75% (PeAF), and 57% (LPeAF). In the Indiana University FIRM registry, FIRM-guided ablation produced high single-procedure success, mostly in patients with nonparoxysmal AF. Data from mapping, acute terminations, and outcomes strongly support the mechanistic role of biatrial rotors and focal sources in maintaining AF in diverse populations. Randomized trials of FIRM-guided ablation and mechanistic studies to determine how rotors form, progress, and regress are needed. Copyright © 2017 American College of Cardiology Foundation.

    Full Text Available Background: Human papilloma virus (HPV is regarded as the main cause in the etiology of cervical cancer. The purpose of our study is to assess the knowledge of medical students about HPV vaccine and to evaluate their opinion on this subject.   Material and Method: The study population consisted of 488 medical students. The survey was composed of questions intended   to obtain information about transmission route of HPV, types of HPV, role of HPV in cervical cancer, whether HPV is treatable or not, which types of HPV the HPV vaccine prevents, the age groups HPV vaccine is administered, the opinions on HPV vaccine and sufficiency of public health, whether female students have underwent vaccination and if not what their drawbacks are.   Results: Mean age of the students participating in the study was 21±4 and 58 % of the patients were female. Out of 448 medical students, 60% of them did not know that HPV was a sexually transmitted disease. Only 55% students knew about the association of HPV with cervical cancer and 52% participants stated that HPV vaccine could not be preventive against cervical cancer. None of female students had been immunized and 67% of female students did not consider getting immunized. Among those who did not consider getting immunized, 70% said they had worries about the safety of the vaccine. Conclusion: Our study results revealed that the knowledge of medical students about HPV is satisfactory, however their knowledge about HPV vaccine, immunization status and desire to be immunized were little.

    Nutrition during pregnancy can impact on the susceptibility of the offspring to CVD. Postnatal consumption of trans-fatty acids (TFA), associated with partially hydrogenated vegetable oil (PHVO), increases the risk of atherosclerosis, whereas evidence for those TFA associated with ruminant-derived dairy products and meat remain equivocal. In this study, we investigate the impact of maternal consumption of dietary PHVO (P) and ruminant milk fat (R) on the development of atherosclerosis in their offspring, using the transgenic apoE*3 Leiden mouse. Dams were fed either chow (C) or one of three high-fat diets: a diet reflecting the SFA content of a 'Western' diet (W) or one enriched with either P or R. Diets were fed during either pregnancy alone or pregnancy and lactation. Weaned offspring were then transferred to an atherogenic diet for 12 weeks. Atherosclerosis was assessed as lipid staining in cross-sections of the aorta. There was a significant effect of maternal diet during pregnancy on development of atherosclerosis (P=0·013) in the offspring with those born of mothers fed R or P during pregnancy displaying smaller lesions that those fed C or W. This was not associated with changes in total or lipoprotein cholesterol. Continuing to feed P during lactation increased atherosclerosis compared with that seen in offspring of dams fed P only during pregnancy (P<0·001). No such effect was seen in those from mothers fed R (P=0·596) or W (P=901). We conclude that dietary TFA have differing effects on cardiovascular risk at different stages of the lifecycle.

    Full Text Available The world population is getting old rapidly; the aging population is the new phenomenon in Iran too. The aim of this meta-analysis was to estimate the overall and subscales mean score of quality of life (QOL based on the Leiden-Padua (LEIPAD questionnaire among the elderly population of Iran. The major international and national databases including; Medlin, Scopus, Science Direct, SID, MagIran, IranMedex, and Irandoc was searched. All cross-sectional studies, which measured the QOL among the elderly population in Iran using the LEIPAD questionnaire, were included. Furthermore, we used the following key words, “Quality of life,” “aging,” “aged,” “elderly,” and “Iran.” Of 2155 records, four articles reminded for the meta-analysis, which involved 628 participants with a mean age of 71.73 ± 4.28 years. The mean scores of QOL in each scale were as follows: 10.80 (9.30–12.31 for physical health, 13.51 (6.81–20.21 for self-care scale, 8.60 (5.07–12.14 for depression and anxiety, 12.48 (10.39–14.58 for cognitive functioning scale, 2.19 (0.67–3.72 for sexual functioning scale, 10.98 (5.87–16.09 for life satisfaction scale, and 5.90 (3.64–8.16 for social desirability scale. This study revealed that the total QOL for the elderly population is relatively low in Iranian society. It is appeared to provide social support, and upgrade their QOL seems to be essential for the elderly population.

    Epidemiological studies have shown mixed findings on the association between hypertension and stroke in the oldest old. Heterogeneity of the populations under study may underlie variation in outcomes. We examined whether the level of physical and cognitive function moderates the association between blood pressure and stroke. We included 513 subjects aged 85 years old from the population-based Leiden 85-plus Study. Systolic blood pressure, diastolic blood pressure, mean arterial pressure, and pulse pressure were measured at baseline. Activities of daily living and Mini-Mental State Examination were assessed to estimate level of physical and cognitive function, respectively. Five-year risk of stroke was estimated with Cox regression analysis. In the entire cohort, there were no associations between various measures of blood pressure and risk of stroke except for the inverse relation between pulse pressure and stroke risk (hazard ratio [HR], 0.80 [95% confidence interval [CI], 0.66-0.98]). Among subjects with impaired physical functioning, higher systolic blood pressure (HR, 0.74 [95% CI, 0.59-0.92]), mean arterial pressure (HR: 0.68 [95% CI, 0.47-0.97]), and pulse pressure (HR, 0.71 [95% CI, 0.55-0.93]) were associated with reduced risk of stroke. Likewise, among subjects with impaired cognitive functioning, higher systolic blood pressure was associated with reduced risk of stroke (HR, 0.80 [95% CI, 0.65-0.98]). In subjects with unimpaired cognitive functioning, higher diastolic blood pressure (HR: 1.98 [95% CI, 1.21-3.22]) and mean arterial pressure (HR, 1.70 [95% CI, 1.08-2.68]) were associated with higher risk of stroke. Our findings suggest that impaired physical and cognitive function moderates the association between blood pressure and stroke.

    Plasminogen-activator inhibitor (PAI)-1 is an important inhibitor of the plasminogen/plasmin system. PAI-1 levels are influenced by the 4G/5G polymorphism in the PAI-1 promoter. We investigated the relationship between the PAI-1 polymorphism and VTE recurrence, and its possible modification by factor V Leiden (FVL) and prothrombin (PTM) mutations. Patients (n=1,069) from the Malmö Thrombophilia Study were followed from discontinuation of anticoagulant treatment until diagnosis of VTE recurrence or the end of the study (maximum follow-up 9.8 years). One hundred twenty-seven patients (11.9 %) had VTE recurrence. PAI-1 was genotyped by TaqMan PCR. Cox regression analysis adjusted for age, sex and acquired risk factors of VTE showed no evidence of an association between PAI-1 genotype and risk of VTE recurrence in the study population as a whole. However, by including an interaction term in the analysis we showed that FVL but not PTM modified the effect of PAI-1 genotype: patients with the 4G allele plus FVL had a higher risk of VTE recurrence [hazard ratio (HR) =2.3, 95 % confidence interval (CI) =1.5-3.3] compared to patients with the 4G allele but no FVL (reference group) or FVL irrespective of PAI-1 genotype (HR=1.8, 95 % CI=1.3-2.5). Compared to reference group, 5G allele irrespective of FVL was associated with lower risk of VTE recurrence only when compared with 4G allele together with FVL. In conclusion, FVL has a modifying effect on PAI-1 polymorphism in relation to risk of VTE recurrence. The role of PAI-1 polymorphism as a risk factor of recurrent VTE may be FVL dependent.

    Few studies have evaluated the risk of pregnancy-related adverse events in asymptomatic relatives of probands for VTE and factor V Leiden or the G20210A variant. The antepartum management of this population ranges from antepartum anticoagulation therapy to clinical surveillance. To evaluate the risk of placenta-mediated pregnancy complications and pregnancy-related VTE in VTE-asymptomatic families of probands with VTE and who are heterozygous carriers of either factor V Leiden or PT-G20210A mutation. One hundred and fifty-eight relatives, who had 415 pregnancies, were retrospectively evaluated. Odds ratios and 95% confidence intervals were calculated to compare pregnancy outcomes between women with and without thrombophilia. In the factor V Leiden group, 22 placenta-mediated pregnancy events of 152 pregnancies (14.4%) were reported, compared with 25 adverse events of 172 pregnancies in the G20210A prothrombin group (14.5%) and 13 adverse events of 91 pregnancies in the non-carrier group (14.2%). Carriers of factor V Leiden or G20210A prothrombin were not associated with a higher risk of pregnancy-adverse outcomes compared with non-carriers: OR 1.02 (95% CI, 0.40-2.25) and 1.25 (95% CI, 0.48-3.24), respectively. Four episodes of pregnancy-associated VTE of 415 pregnancies (0.96%) were recorded. Two episodes of VTE in the G20210A group, one in the factor V Leiden group, and one episode in the non-carrier group were noted. In VTE-asymptomatic relatives of probands with VTE, the presence of factor V Leiden or the G20210A prothrombin mutation in heterozygosis should not lead to a decision to instigate antepartum prophylaxis. © 2012 John Wiley & Sons A/S.

  2. Lipidomics reveals multiple pathway effects of a multi-components preparation on lipid biochemistry in ApoE*3Leiden.CETP mice.

    Full Text Available BACKGROUND: Causes and consequences of the complex changes in lipids occurring in the metabolic syndrome are only partly understood. Several interconnected processes are deteriorating, which implies that multi-target approaches might be more successful than strategies based on a limited number of surrogate markers. Preparations from Chinese Medicine (CM systems have been handed down with documented clinical features similar as metabolic syndrome, which might help developing new intervention for metabolic syndrome. The progress in systems biology and specific animal models created possibilities to assess the effects of such preparations. Here we report the plasma and liver lipidomics results of the intervention effects of a preparation SUB885C in apolipoprotein E3 Leiden cholesteryl ester transfer protein (ApoE*3Leiden.CETP mice. SUB885C was developed according to the principles of CM for treatment of metabolic syndrome. The cannabinoid receptor type 1 blocker rimonabant was included as a general control for the evaluation of weight and metabolic responses. METHODOLOGY/PRINCIPAL FINDINGS: ApoE*3Leiden.CETP mice with mild hypercholesterolemia were divided into SUB885C-, rimonabant- and non-treated control groups. SUB885C caused no weight loss, but significantly reduced plasma cholesterol (-49%, p<0.001, CETP levels (-31%, p<0.001, CETP activity (-74%, p<0.001 and increased HDL-C (39%, p<0.05. It influenced lipidomics classes of cholesterol esters and triglycerides the most. Rimonabant induced a weight loss (-9%, p<0.05, but only a moderate improvement of lipid profiles. In vitro, SUB885C extract caused adipolysis stimulation and adipogenesis inhibition in 3T3-L1 cells. CONCLUSIONS: SUB885C, a multi-components preparation, is able to produce anti-atherogenic changes in lipids of the ApoE*3Leiden.CETP mice, which are comparable to those obtained with compounds belonging to known drugs (e.g. rimonabant, atorvastatin, niacin.

    This article is an analysis of the novel Die neuen Leiden des jungen W. (1973) in the light of its intertextuality with Goethe’s, Defoe’s and Salinger’s texts. It has been suggested that Plenzdorf's novel creates a stylistic and ideological world, which is instigating for the literary paradigms of the Socialist Realism of the 70s in East Germany. Twenty years after the Fall of the Berlin Wall, this created world in the novel seems to be up-to-date or even paradigmatic for the current repre...

    Marković Milan M.

    2012-01-01

    Full Text Available Adoption of the UN Convention on the Right of Persons with Disabilities (2006 brought about a core shift to how the international community and human rights law see and treat human disability in general. This paradigm shift materilizes itself in a number of provisions ranging from those which catalogue the proclaimed human rights as they are in the context of special implementation and protection of people with disabilities, to those that introduce a level of specificity in light of their holders' particular needs. But the strongest presence of the shift to this regard can be found in the Article 12 CRPD that sheds new light on the concept of (legal capacity of people with (mental disabilites. According to this norm and put quite simply - there should be no difference in observing and treating capacity of a person with disabilities to that of any other person. This is not only the matter of prohibiting discrimination on grounds of mental impairments, but furthermore preventing the system from establishing a classification in which a person with psychosocial or intellectual impairment would be a second-rate citizen, an object of law or a victim of legal, social and family abuse, someone who is a burden to his entire environment, someone who does not have a say in any case concerning his own life and wellbeing. Legal capacity should not be a goal to be fighting for, but a universal human right. Of course and unfortunatelly, such a shift is purely a formal one, when not causing due reform within the national systems and without proper implementation in the member states. What is thought urgently needed and directly required by the given provision is removing the system features that allow deprivation of legal capacity on the bases of mental impairments and introducing a humane and human rights oriented model in which the decision making of these people would be autonomous and supported, and with only very restricted exceptions, done by them and not

    As part of the NSF-NIEHS Center for Oceans and Human Health at the University of Miami, research is being conducted into the remote sensing of ocean color signatures associated with the occurrence of Harmful Algal Blooms (HABs). Data from the MODerate-resolution Imaging Spectroradiometer (MODIS) are down-linked at the University of Miami's Center for Southeastern Tropical Advanced Remote Sensing (CSTARS) and processed in near-real time to produce mapped fields of water leaving radiance in the ocean color bands, derived quantities including inherent optical properties (IOPs) of seawater, chlorophyll concentration, and sea-surface temperature. Images of these fields are available in near-real time on a web-server. The server also provides access to the data files themselves. One of the applications currently being researched using these data is the identification of HABs over the Central West Florida Shelf where blooms of the toxic dinoflagellate Karenia brevis have a nearly annual occurance. Since chlorophyll concentration alone cannot be used as a unique variable to determine algal taxonomy, other spectral features or optical properties must be brought into play to discriminate among different phytoplankton types. A published technique developed for SeaWiFS (Sea-viewing Wide Field-of-view Sensor) to detect K. brevis (based on high concentration of chlorophyll and low particulate backscatter) was transitioned to measurements of Terra MODIS and replicated the results. These were confirmed by comparisons with in situ measurements. This technique is currently being applied to a multi-year time series of remote measurements from the Aqua MODIS and tested against ship-based data.

    Full Text Available Thrombosis is a result of the interaction between predisposing genetic polymorphisms and acquired risk factors. The two prothrombotic polymorphisms which are most frequently associated with thrombosis are factor V (FV Leiden and the prothrombin (PT G20210A mutation. The objective of this work was to investigate the prevalence of both factors in the central-south region of Chile. Determination of the frequency was carried out by means of a genetic analysis of 1200 healthy, non-native individuals. The mutation of FV Leiden was found in 1.25% of the population and the PT G20210A mutation in 1.33%. None of the individuals were homozygosis or had both polymorphisms. The prevalences of FV Leiden and the PT G20210A mutation are less common in the healthy population.A trombose pode ser o resultado da interação de polimorfismo genético e fatores de riscos adquiridos. Os polimosfirmos protrombóticos mais frequentes são fator V (FV Leiden e a mutação da protrombina (PT G20210A. O objetivo deste trabalho foi investigar a prevalência de ambos os polimorfismos na região centro-sul do Chile. Foram realizadas análises genéticas (PCR RFLP de 1.200 pessoas saudáveis, não nativas da região. Foram encontrados 1,25% de mutação do Fator V Leiden e 1,33% da mutação da protrombina G20210A. Não foi detectada homozigose em ambos os polimorfismos. A prevalência de FV Leiden e da mutação G20210A é baixa na população estudada.

    We present the case of a 53-year-old Caucasian male smoker with remote history of left lower extremity deep venous thrombosis (DVT) and a strong family history of thrombosis, who presented to the Center for Wound Healing at MedStar Georgetown University Hospital with spontaneous left leg ulceration. Prothrombotic evaluation showed homozygosity for the factor V Leiden (FVL) mutation. Therapeutic anticoagulation was commenced with warfarin (Coumadin®) and the patient underwent successful debridement and Apligraf® followed by split-thickness skin graft (STSG) of two wounds. He had an uneventful postoperative course and on the 27th postoperative day the grafts were 95% intact. However, by postoperative day 41 there was 10% graft loss, and over the subsequent 2 weeks both grafts necrosed. On further questioning, it transpired that the patient had discontinued his warfarin on postoperative day 37 because he thought that it was no longer necessary. The patient is enrolled in the Wound Etiology and Healing (WE-HEAL) study, and at the time of the original graft, residual skin fragments from the STSG were transplanted onto a nude mouse for development of an animal model of wound healing. The mouse graft was successful and was harvested at postoperative day 87 for pathological examination. We review the mechanisms by which prothrombotic states, particularly FVL mutation, can contribute to skin graft failure and delayed wound healing. This case highlights the importance of considering prothrombotic conditions in patients with spontaneous leg ulcerations and the impact of therapeutic anticoagulation on healing. It further allows us to demonstrate the efficacy of the animal model in which residual fragments of STSG tissue are utilised for transplant onto nude mice for manipulation in the laboratory. © 2013 The Authors.

    Bombay phenotype is one of the rare phenotypes in the ABO blood group system that fails to express ABH antigens on red blood cells. Nonsense or missense mutations in fucosyltransfrase1 (FUT1) and fucosyltransfrase2 (FUT2) genes are known to create this phenotype. This blood group is compatible with all other blood groups as a donor, as it does not express the H antigen on the red blood cells. In this study, we describe the establishment of human induced pluripotent stem cells (iPSCs) from the dermal fibroblasts of a Bombay blood-type individual by the ectopic expression of established transcription factors Klf4, Oct4, Sox2, and c-Myc. Sequence analyses of fibroblasts and iPSCs revealed a nonsense mutation 826C to T (276 Gln to Ter) in the FUT1 gene and a missense mutation 739G to A (247 Gly to Ser) in the FUT2 gene in the Bombay phenotype under study. The established iPSCs resemble human embryonic stem cells in morphology, passaging, surface and pluripotency markers, normal karyotype, gene expression, DNA methylation of critical pluripotency genes, and in-vitro differentiation. The directed differentiation of the iPSCs into hematopoietic lineage cells displayed increased expression of the hematopoietic lineage markers such as CD34, CD133, RUNX1, KDR, alpha-globulin, and gamma-globulin. Such specific stem cells provide an unprecedented opportunity to produce a universal blood group donor, in-vitro, thus enabling cellular replacement therapies, once the safety issue is resolved.

    Full Text Available The article substantiates the model of “reverse inclusion” in the interconnection of sociostructural, sociocultural and spatial aspects. In addition to these aspects, the paper describes the socio-legal and socio-pedagogical foundations of the model. Along with the key category of inclusion the following categories are revealed: “disability”, “disabled person”, “social barrier”, “inclusive social strategy”, and “inclusive strategy in education”. “Reverse inclusion” is opposed to the dominant model of direct inclusion. Due to the fact that the article is of a theoretical and methodological nature, factual data play an illustrative role. The empirical base is represented by secondary data, as well as by some references to the authors’ research of 2016 conducted by the staff of the research laboratory of the Moscow State University of Humanities and Economics for purposes of vocational guidance; in this research a series of 27 in-depth interviews were carried out with students with musculoskeletal disorders studying at MSUHE.

    Academic hospitals and medical schools with research tissue repositories often derive many of their internal human specimen acquisitions from their site's surgical pathology service. Typically, such acquisitions come from appropriately consented tissue discards sampled from surgical resections. Because the practice of surgical pathology has patient care as its primary mission, competing needs for tissue inevitably arise, with the requirement to preserve adequate tissue for clinical diagnosis being paramount. A set of best-practice gross pathology guidelines are summarized here, focused on the decision for tissue banking at the time specimens are macroscopically evaluated. These reflect our collective experience at Washington University School of Medicine, and are written from the point of view of our site biorepository. The involvement of trained pathology personnel in such procurements is very important. These guidelines reflect both good surgical pathology practice (including the pathologic features characteristic of various anatomic sites) and the typical objectives of research biorepositories. The guidelines should be helpful to tissue bank directors, and others charged with the procurement of tissues for general research purposes. We believe that appreciation of these principles will facilitate the partnership between surgical pathologists and biorepository directors, and promote both good patient care and strategic, value-added banking procurements.

    Full Text Available Abstract Background Massive parallel sequencing has the potential to replace microarrays as the method for transcriptome profiling. Currently there are two protocols: full-length RNA sequencing (RNA-SEQ and 3'-tag digital gene expression (DGE. In this preliminary effort, we evaluated the 3' DGE approach using two reference RNA samples from the MicroArray Quality Control Consortium (MAQC. Results Using Brain RNA sample from multiple runs, we demonstrated that the transcript profiles from 3' DGE were highly reproducible between technical and biological replicates from libraries constructed by the same lab and even by different labs, and between two generations of Illumina's Genome Analyzers. Approximately 65% of all sequence reads mapped to mitochondrial genes, ribosomal RNAs, and canonical transcripts. The expression profiles of brain RNA and universal human reference RNA were compared which demonstrated that DGE was also highly quantitative with excellent correlation of differential expression with quantitative real-time PCR. Furthermore, one lane of 3' DGE sequencing, using the current sequencing chemistry and image processing software, had wider dynamic range for transcriptome profiling and was able to detect lower expressed genes which are normally below the detection threshold of microarrays. Conclusion 3' tag DGE profiling with massive parallel sequencing achieved high sensitivity and reproducibility for transcriptome profiling. Although it lacks the ability of detecting alternative splicing events compared to RNA-SEQ, it is much more affordable and clearly out-performed microarrays (Affymetrix in detecting lower abundant transcripts.

    Human adenovirus species D (HAdV-D), which is composed of clinically and epidemiologically important pathogens worldwide, contains more taxonomic "types" than any other species of the genus Mastadenovirus, although the mechanisms accounting for the high level of diversity remain to be disclosed. Recent studies of known and new types of HAdV-D have indicated that intertypic recombination between distant types contributes to the increasing diversity of the species. However, such findings raise the question as to how homologous recombination events occur between diversified types since homologous recombination is suppressed as nucleotide sequences diverge. In order to address this question, we investigated the distribution of the recombination boundaries in comparison with the landscape of intergenomic sequence conservation assessed according to the synonymous substitution rate (dS). The results revealed that specific genomic segments are conserved between even the most distantly related genomes; we call these segments "universally conserved segments" (UCSs). These findings suggest that UCSs facilitate homologous recombination, resulting in intergenomic segmental exchanges of UCS-flanking genomic regions as recombination modules. With the aid of such a mechanism, the haploid genomes of HAdV-Ds may have been reshuffled, resulting in chimeric genomes out of diversified repertoires in the HAdV-D population analogous to the MHC region reshuffled via crossing over in vertebrates. In addition, some HAdVs with chimeric genomes may have had the opportunity to avoid host immune responses thereby causing epidemics. Copyright © 2014 Elsevier B.V. All rights reserved.

    In public health, the issue of pharmaceutical pricing is a perennial problem. Recent high-profile examples, such as the September 2015 debacle involving Martin Shkreli and Turing Pharmaceuticals, are indicative of larger, systemic difficulties that plague the pharmaceutical industry in regards to drug pricing and the impact it yields on their reputation in the eyes of the public. For public health ethics, the issue of pharmaceutical pricing is rather crucial. Simply, individuals within a population require pharmaceuticals for disease prevention and management. In order to be effective, these pharmaceuticals must be accessibly priced. This analysis will explore the notion of corporate social responsibility in regards to pharmaceutical pricing with an aim of restoring a positive reputation upon the pharmaceutical industry in the public eye. The analysis will utilize the 2005 United Nations Educational, Scientific, and Cultural Organization's Universal Declaration on Bioethics and Human Rights (UDBHR) to establish implications regarding the societal responsibilities of pharmaceutical companies in a global context. To accomplish this, Article 14 of the UDBHR-social responsibility and health-will be articulated in order to advocate a viewpoint of socially responsible capitalism in which pharmaceutical companies continue as profit-making ventures, yet establish moral concern for the welfare of all their stakeholders, including the healthcare consumer.

    Factor V Leiden (FVL) has been, by far, the most investigated gene mutation, with 26 studies to date, on its role in arterial strokes. Overall, a meta-analysis of all these studies taken together showed that carriers of the Factor V Leiden allele were 1.33times more likely to develop arterial strokes when compared to controls. We subjected a highly select subset of young strokes, with large vessel infarcts, to genetic analysis for FVL mutation and compared them with matched healthy controls to look for a statistically significant association. In this prospective study, 6/120 cases (5%) and 2/120 controls (1.6%) were positive for heterozygous FVL (G1691A) mutation. The higher prevalence of FVL mutation in cases (5%) compared to controls (1.6%) did not show statistical significance with a Pearson's Chi square P value of 0.15. The Odds Ratio (OR) for risk of large vessel disease in FVL positive cases was 3.10 (95% CI of 0.61-15.7). FVL mutation (G1691A) in young Indian subjects with ischemic strokes does not seem to be significantly associated with large vessel disease. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Normal iron levels are required to prevent thrombocytosis by inhibiting thrombopoiesis. Thrombocytosis is usually associated with a mild iron deficiency and is the result of a lack of inhibition of thrombopoiesis. Study participants were 430 iron deficiency anemia (IDA) patients. Ten (10) mL of venous blood were collected for the subjects. Ferritin analysis was done by ELISA method while Hemogram analysis was done by auto-analyzer. Factor V Leiden, PRTG20210A, and MTHFR C677T genotype analysis was performed by PCR-RFLP method. Among the patients, 9 were heterozygous (G>A) and 2 were homozygous (A>A) carrier of FV Leiden; while 20 were heterozygous (C>T) and 3 were homozygous (T>T) for MTHFR polymorphism. None of the patient was identified with PT mutation. Patients with thrombosis gene marker had lower hemoglobin, mean corpuscular volume, mean corpuscular haemoglobin levels, and mean corpuscular hemoglobin concentration than patients without thrombosis gene marker. Serum ferritin was elevated in subject with the absence of thrombosis gene markers. Our data suggest a high impact of inherited hypercoagulability risk factors in the pathogenesis of IDA and its complications.
