Venous thromboembolism (VTE) includes deep vein thrombosis and pulmonary embolism, and a combination of environmental and genetic risk factors contributes to VTE risk. Within environmental risk factors, some are provoking (e.g., cancer, surgery, trauma or fracture, immobilization, pregnancy and the postpartum period, long-distance travel, hospitalization, catheterization, and acute infection) and others are nonprovoking (e.g., age, sex, race/ethnicity, body mass index and obesity, oral contraceptive or hormone therapy use, corticosteroid use, statin use, diet, physical activity, sedentary time, and air pollution)...

Professor Emil Redlich (1866-1930) of the University of Vienna was born 150 years ago. Raised in a humble environment, he became an eminent researcher and neurology scholar, and succeeded in laying some of the key foundations of neuroanatomy and neuropathology. His name is linked to medical eponyms that define the dorsal root entry zone into the spinal cord, epidemic disseminated encephalomyelitis, narcolepsy, senile plaques and dementia. As its first director, he managed to organize the Maria-Theresien-Schlössel into a first-class neuropsychiatric hospital...

Efficient and correct evaluation of sampling results with respect to hypotheses about the concentration or distribution of bacteria generally requires knowledge about the performance of the detection method. To assess the sensitivity of the detection method an experiment is usually performed where the target matrix is spiked (i.e. artificially contaminated) with different concentrations of the bacteria, followed by analyses of the samples using the pre-enrichment method and the analytical detection method of interest...

Recent studies have shown that intratumoral heterogeneity (ITH) is prevalent in clear cell renal cell carcinoma (ccRCC), based on DNA sequencing and chromosome aberration analysis of multiple regions from the same tumor. VHL mutations were found to be universal throughout individual tumors when it occurred (ubiquitous), while the mutations in other tumor suppressor genes tended to be detected only in parts of the tumors (subclonal). ITH has been studied mostly by DNA sequencing in limited numbers of samples, either by whole genome sequencing or by targeted sequencing...

OBJECTIVE: Renal conservation (retention) of fluid might affect the outcome of hospital care and can be indicated by increased urinary concentrations of metabolic waste products. We obtained a reference material for further studies by exploring the prevalence of fluid retention in a healthy population. METHODS: Spot urine sampling was performed in 300 healthy hospital workers. A previously validated algorithm summarized the urine-specific gravity, osmolality, creatinine, and color to a fluid retention index (FRI), where 4...

PURPOSE OF REVIEW: Mentoring is fundamentally valuable and important to students considering a path into our specialty, as well as to colleagues already in it and with ambition to advance. General principles and personal experiences are collected and described to help inform future mentors and to reinforce the value of having a mentor and the satisfaction (and work) that is associated with such a role. RECENT FINDINGS: Detecting a latent talent among medical students or residents may be challenging but is worth the effort to develop personal careers and the specialty itself...

Carbon-based suspension electrodes are currently intensively investigated for emerging electrochemical systems, such as flow batteries, flow capacitors, and capacitive deionization cells. The main limitation of such electrodes is their low electric conductivity, which is typically orders of magnitude lower than that of traditional static carbon electrodes. Two main categories of suspension electrodes exist: 1) slurry electrodes where particles are not significantly affected by gravity, and 2) fluidized bed electrodes where particles are affected by gravity...

Sensationalized representations of autistic families in film and other media frequently feature violent encounters between mothers and sons. This essay analyzes two media stories and three films that suggest how limited-and therefore misleading-popular representations of the autism family are. Except for one of the films, these representations blame the problem of adult autistic dependency on either monstrous autism or bad mothering. Doing so elides collective social responsibility for autism care and denies the reality that autistic adults continue to have complex dependency needs that families cannot always meet...

Neural activity in monkey motor cortex (M1) and dorsal premotor cortex (PMd) can reflect a chosen movement well before that movement begins. The pattern of neural activity then changes profoundly just before movement onset. We considered the prediction, derived from formal considerations, that the transition from preparation to movement might be accompanied by a large overall change in the neural state that reflects when movement is made rather than which movement is made. Specifically, we examined "components" of the population response: time-varying patterns of activity from which each neuron's response is approximately composed...

Tuberculosis is an infectious disease and is a major health problem in developing countries like India. The disease is prevalent mainly in the underprivileged sections of the society. However, the same is not always true and even the well to do sections are also affected by this disease. The lack of knowledge in the masses and the communities is a factor that contributes largely to the spread of the disease. In such a scenario, there is always a need for new and innovative ideas to create mass awareness about tuberculosis...

INTRODUCTION: The offer of pre-exposure prophylaxis (PrEP) is recommended as an additional option for HIV prevention for people at substantial risk of HIV infection as part of combination HIV prevention approaches. Implementing this depends on integrating PrEP in public health programmes that address risky practices with evidence-based interventions, and that operate in an enabling legal and policy environment for the delivery of health services to those at higher risk of HIV infection...

Objective: To analyze the prognosis of surviving monochorionic co-twin after single intrauterine fetal demise (sIUFD). Methods: Retrospectively analyzed the twin pregnancy cases admitted in Peking University Third Hospital between Jan 2008 and Feb 2015. We recorded perinatal characteristics, neuroimage in co-twin, and followed up the neonatal outcome. Results: 47 cases were found, including 45 cases of monochorionic diamniotic (MCDA) and 2 cases of monochorionic monoamniotic (MCMA). Median gestational age at sIUFD was 27 weeks...

The 2015 European Guidelines on Pulmonary Hypertension did not cover only pulmonary arterial hypertension (PAH) but also some aspects of pulmonary hypertension (PH) associated with chronic lung disease. The European Guidelines point out that the drugs currently used to treat patients with PAH (prostanoids, endothelin receptor antagonists, phosphodiesterase-5 inhibitors, sGC stimulators) have not been sufficiently investigated in other forms of PH. Therefore, the European Guidelines do not recommend the use of these drugs in patients with chronic lung disease and PH...

Tropical shrimp is of considerable economic importance in the world but is highly perishable due to microbial and chemical degradation. Biopreservation is a food preservation technology based on the addition of "positive" bacteria able to kill or prevent the growth of undesirable microorganisms. Two strains of lactic acid bacteria (LAB) have previously been selected for a biopreservation strategy: Lactococcus piscium CNCM I-4031, for its ability to prevent the sensory deterioration of seafood and Carnobacterium divergens V41, which inhibits growth of Listeria monocytogenes...

Combining imaging with correlation spectroscopy, as in raster image correlation spectroscopy (RICS), makes it possible to extract molecular translational diffusion constants and absolute concentrations, and determine intermolecular interactions from single-channel or multicolor confocal laser-scanning microscopy (CLSM) images. Region-specific RICS analysis remains very challenging because correlations are always calculated in a square region-of-interest (ROI). In this study, we describe a generalized image correlation spectroscopy algorithm that accepts arbitrarily shaped ROIs...

One of the biggest challenges in bioimaging of nanoparticles is how to identify integral particles from bulk signals of probes. Signals of free probes are always mistakenly counted into total signals of particles. In this study, in vivo fate of intravenous polymeric micelles (PMs, mPEG2.5k-PDLLA2.5k) was explored using a highly sensitive near-infrared environment-responsive fluorescent probe. This probe is able to emit fluorescence when embedded in nanocarriers but quench spontaneously and absolutely upon release into water, based on the aggregation-caused quenching effect, which means that the interference generated by free probes can be completely diminished...

BACKGROUND AND PURPOSE: When fractionation schemes for hypofractionation and stereotactic body radiotherapy are considered, a reliable cell survival model at high dose is needed for calculating doses of similar biological effectiveness. An alternative to the LQ-model is the track-event theory which is based on the probabilities for one- and two two-track events. A one-track-event (OTE) is always represented by at least two simultaneous double strand breaks. A two-track-event (TTE) results in one double strand break...

Paravalvular leak (PVL) remains as uncommon but serious complication after surgical prosthetic valve implantation. PVL when associated which congestive heart failure, hemolytic anemia, or infective endocarditis may require percutaneous treatment. High-surgical risk is common in this population. Dedicated PVL devices are lacking often limiting optimal treatment.

Background: The outcome of the patients after liver transplant is complex and to characterize the risk for complications is not always easy. In this context, the hepatic post-reperfusion biopsy is capable of portraying alterations of prognostic importance. Aim: To compare the results of liver transplantation, correlating the different histologic features of the hepatic post-reperfusion biopsy with graft dysfunction, primary non-function and patient survival in the first year after transplantation...
