Purpose: This study estimated the overall magnitude of Creutzfeldt-Jakob disease (iCJD) based on dura graft cases in Korea using a mathematical model. Methods: We estimated the number of annual cases of dura grafts performed between 1980 and 1995 by applying the proportion of dura grafts recorded by the Health Insurance Review Agency claim dataset in Korea to the number of nationwide neurosurgery cases. The distribution of the incubation period was assumed to fall under a Weibull distribution with density function or a log-logistic distribution with density function...

Two major definitions of metabolic syndrome have been proposed. One focuses on accumulation of risk factors such as the American Heart Association (AHA) and National Heart, Lung and Blood Institute (NHLBI) criteria; and the other focuses on abdominal obesity such as the International Diabetes Federation (IDF) and Japanese criteria. The latter consider waist circumference as an obligatory component, whereas the former does not. In 2009, the IDF, NHLBI, AHA and the other organizations attempted to unify these criteria, and waist circumference is no longer an obligatory component...

Genetic determinism is nowadays largely questioned and widely criticized. However, if we look at the history of biology in the last one hundred years, we realize that genetic determinism has always been controversial. Why, then, did it acquire such relevance in the past despite facing longstanding criticism? Through the analysis of some of the ambitious expectations of future scientific applications, this article explores the possibility that part of the historical success of genetic determinism lies in the powerful rhetorical strategies that have connected the germinal matter with alluring bio-technological visions...

INTRODUCTION: Population aging is set to increase the elder dependency ratio, causing a rapid increase in healthcare expenditures and financial burden on the government. This study aims to construct an aging score from age-related diseases and to perform longitudinal analyses to examine the association between personal income and aging. METHODS: A total of 86,838 subjects drawn from a community with 384,617 residents in northern Taiwan were examined. Personal income and aging-related diseases were measured from the National Health Insurance database during 1997-2010...

BACKGROUND AND OBJECTIVES: The negative symptoms of schizophrenia are related to lower social functioning even in non-clinical samples, but little is known about the distinct social consequences of motivational and expressive negative symptoms. In this study we focused on expressive negative symptoms and examined how these symptoms and varying degrees of pro-social facial expressiveness (smiling and mimicry of smiling) relate to the social evaluations by face-to-face interaction partners and to social support...

Synthetic glucocorticoids have been detected in environmental waters and their biological potency have raised concerns of their impact on aquatic vertebrates especially fish. In this study, developing zebrafish larvae exposed to representative glucocorticoids (dexamethasone, prednisolone and triamcinolone) at 50 pM to 50 nM from 3 h post-fertilisation to 5 days post-fertilisation were investigated. Microarray analysis identified 1255, 1531, and 2380 gene probes, which correspondingly mapped to 660, 882 and 1238 human/rodent homologs, as deregulated by dexamethasone, prednisolone and triamcinolone, respectively...

Graphene oxide (GO) has unique physicochemical properties and also has a potentially widespread use in every field of daily life (industry, science, medicine). Demand for nanotechnology is growing every year, and therefore many aspects of its toxicity and biocompatibility still require further clarification. This research assesses the in vivo toxicity of pure and manganese ion-contaminated GO that were administrated to Acheta domesticus with food (at 200mgkg(-1) of food) throughout their ten-day adult life...

The articular cartilage and subchondral bone may have potential crosstalk in the development and progression of osteoarthritis (OA). Strontium ranelate (SrR) has the ability to dissociate the bone remodeling process and to change the balance between bone resorption and bone formation. Its effect on subchondral bone makes it a potential disease- modifying osteoarthritis drug (DMOAD) in the treatment of OA. The aim of the current review is to summarize up-to-date pharmacological and clinical data of SrR for OA treatment...

The mechanism of action of pertuzumab, a recombinant anti-HER2 humanized monoclonal antibody, is complementary to trastuzumab's. On June 8, 2012, the Food and Drug Administration approved the combination of pertuzumab with trastuzumab and docetaxel as first-line treatment of HER2-positive metastatic breast cancer. Furthermore, pertuzumab is the first drug to be approved in the neoadjuvant setting using a pathological complete response as an endpoint. Areas covered: The review provides insights into the main mechanisms of action of pertuzumab...

Advancements in microbial identification occur increasingly faster as more laboratories explore, refine and extend the use of mass spectrometry in the field of microbiology. Areas covered: This review covers the latest knowledge found in the literature for quick identification of various classes of bacterial pathogens known to cause human infection by the use of MALDI-TOF MS technology. Except for identification of bacterial strains, more researchers try to "battle time" in favor of the patient. These novel approaches to identify bacteria directly from clinical samples and even determine antibiotic resistance are extensively revised and discussed...

The Universal Declaration of Human Rights recognizes the family as the basic cell of society, highlighting its importance, the need to protect it, to promote it as a natural and fundamental group unit of society. To reflect on the effects that the actual culture is in the family is important from the situation as it is now presented, then move to raise the changes seen necessary to ensure their own future and that of their habitat that is Earth. To accomplish this first task some study results World Family Map 2015 is glossed...

Food and agricultural systems are in large part driven by technology. Together with public policy, the kinds of technologies that are induced into, or chosen by actors in, food systems, dictates their structure and activities. The ″Big Story″ or ideology which underlies research, development and adoption of technologies provides the justification for choices we make about the future of the food system. A combination of productionism -more is better, and ″feed the world″- is what governs, and seems to be what will govern Western food systems...

This article argues that it is necessary to go back to Potter's proposal to rediscover a concept of bioethics wider than medical ethics, and strongly connected to environmental ethics. The two disciplines share, among others, the following dimensions: the consciousness of the sin as a consequence of recent technological developments; the need for a salvation; the need for a science of survival; wisdom as a possible solution. Referring to the latter, the work of Van Rennselaer Potter (father of bioethics) and Arne Næss (father of deep ecology, and in a broader sense, of environmental ethics) are particularly linked: it seems that wisdom should be the virtue providing answers about our way of dwelling the world...

While environmental ethics has successfully established itself in philosophy, as presently conceived it is still largely irrelevant to grappling the global ecological crisis because, as Alasdair MacIntyre has argued, ethical philosophy itself is in grave disorder. MacIntyre's historically oriented recovery of virtue ethics is defended, but it is argued that even MacIntyre was too constrained by received assumptions to overcome this disorder. As he himself realized, his ideas need to be integrated and defended through philosophical anthropology...

Silicene, germanene and stanene are part of a monoelemental class of two-dimensional (2D) crystals termed 2D-Xenes (X = Si, Ge, Sn and so on) which, together with their ligand-functionalized derivatives referred to as Xanes, are comprised of group IVA atoms arranged in a honeycomb lattice - similar to graphene but with varying degrees of buckling. Their electronic structure ranges from trivial insulators, to semiconductors with tunable gaps, to semi-metallic, depending on the substrate, chemical functionalization and strain...

Collecting cases for case-control genetic association studies can be time-consuming and expensive. In some situations (such as studies of late-onset or rapidly lethal diseases), it may be more practical to identify family members of cases. In randomly ascertained cohorts, replacing cases with their first-degree relatives enables studies of diseases that are absent (or nearly absent) in the cohort. We refer to this approach as genome-wide association study by proxy (GWAX) and apply it to 12 common diseases in 116,196 individuals from the UK Biobank...

The extent of heterogeneity among driver gene mutations present in naturally occurring metastases-that is, treatment-naive metastatic disease-is largely unknown. To address this issue, we carried out 60× whole-genome sequencing of 26 metastases from four patients with pancreatic cancer. We found that identical mutations in known driver genes were present in every metastatic lesion for each patient studied. Passenger gene mutations, which do not have known or predicted functional consequences, accounted for all intratumoral heterogeneity...

Existing estimates of sociodemographic disparities in chronic pain in the United States are based on cross-sectional data, often treat pain as a binary construct, and rarely test for nonresponse or other types of bias. This study uses 7 biennial waves of national data from the Health and Retirement Study (1998-2010; n = 19,776) to describe long-term pain disparities among older (age 51+) American adults. It also investigates whether pain severity, reporting heterogeneity, survey nonresponse, and/or mortality selection might bias estimates of social disparities in pain...
