Herein, we examined if acute or chronic resistance exercise affected markers of skeletal muscle LINE-1 retrotransposon activity. In study 1, 10 resistance-trained college-aged males performed three consecutive daily back squat sessions, and vastus lateralis biopsies were taken prior to (Pre), 2 h following session 1 (Post1), and 3 days following session 3 (Post2). In study 2, 13 untrained college-aged males performed a full-body resistance training program (3 d/wk), and vastus lateralis biopsies were taken prior to (week 0) and ~72 h following training cessation (week 12)...

Iliac venous aneurysms are rare vascular abnormalities that may be manifested by abdominal masses, pelvic tenderness, or hypovolemia and may lead to rupture, thrombosis, pulmonary embolism, paradoxical embolism, or death. Inferior vena cava agenesis, like venous aneurysm, is an uncommon condition that may present with deep venous thrombosis. This report describes a patient with inferior vena cava agenesis and iliac venous aneurysm rupture treated with emergent iliocaval reconstruction and endovascular stent graft placement...

Although those identifying as "Hispanic or Latino" experience lower adult mortality than the more socioeconomically advantaged non-Hispanic white population, the ethnic category Hispanic conceals variation by country of origin, nativity, age, and immigration experience. The current analysis examines adult mortality differentials among 12 Hispanic subgroups by region of origin and nativity, and non-Hispanic whites, adjusting for socioeconomic and demographic characteristics. We use the National Health Interview Survey Linked Mortality Files pooled 1990-2009 to obtain sufficient sample of each subgroup to calculate mortality estimates by sex and age group (25-64, 65+)...

National data indicate that U.S. whites have a higher prevalence of smoking compared to non-whites. Group position theory and public opinion data suggest racial differences in immigration concern. This study examines whether immigration concern mediates the racial difference in smoking. Drawing on the 2012 General Social Survey, the 2012 American National Election Study, and the 2006 Portraits of American Life Study, immigration concern was associated with smoking, controlling for covariates across all three nationally representative surveys...

REVIEW
Emma U Hammarlund, Kristoffer von Stedingk, Sven Påhlman
Animal diversification on Earth has long been presumed to be associated with the increasing extent of oxic niches. Here, we challenge that view. We start with the fact that hypoxia (<1-3% O2) maintains cellular immaturity (stemness), whereas adult stem cells continuously-and paradoxically-regenerate animal tissue in oxygenated settings. Novel insights from tumour biology illuminate how cell stemness nevertheless can be achieved through the action of oxygen-sensing transcription factors in oxygenated, regenerating tissue...

A 24-year-old woman presented with a history of persistent vomiting for at least 3 months. This resulted in severe dehydration with risk of acute kidney injury. In addition to volume depletion, loss of gastric fluid resulted in a specific metabolic derangement-hypokalaemic, hypochloraemic normal anion gap metabolic alkalosis with a reduced ionised calcium concentration and paradoxical aciduria. These metabolic changes were reflected in her ECG. Investigation demonstrated acquired gastric outflow tract obstruction secondary to a pyloric peptic ulcer...

Goncalo Silva, Viriato Semiao
The first nonequilibrium effect experienced by gaseous flows in contact with solid surfaces is the slip-flow regime. While the classical hydrodynamic description holds valid in bulk, at boundaries the fluid-wall interactions must consider slip. In comparison to the standard no-slip Dirichlet condition, the case of slip formulates as a Robin-type condition for the fluid tangential velocity. This makes its numerical modeling a challenging task, particularly in complex geometries. In this work, this issue is handled with the lattice Boltzmann method (LBM), motivated by the similarities between the closure relations of the reflection-type boundary schemes equipping the LBM equation and the slip velocity condition established by slip-flow theory...

Thin shells are characterized by a high cost of stretching compared to bending. As a result isometries of the midsurface of a shell play a crucial role in their mechanics. In turn, curves on the midsurface with zero normal curvature play a critical role in determining the number and behavior of isometries. In this paper, we show how the presence of these curves results in a decrease in the number of linear isometries. Paradoxically, shells are also known to continuously fold more easily across these rigidifying curves than other curves on the surface...

BACKGROUND: The very significant benefit of P2Y12 receptor inhibitor administration in patients with ST-elevation myocardial infarction (STEMI), in reducing future ischaemic events and stent thrombosis, is undisputed. Morphine analgesia is very frequently co-administered to these patients for pain relief, along with antiplatelet therapy, at the time of presentation, and prior to reperfusion with primary percutaneous coronary intervention. METHODS: Research and online content related to opiates use in STEMI was reviewed...

With over 1.5 billion people, East Asians are the most populous race in the world. Health status in this population is an important global issue. In the contemporary trials of antithrombotic treatment, East Asian patients have a lower risk for atherothrombotic diseases (especially, coronary artery disease [CAD]) and a higher risk for bleeding (especially, gastrointestinal bleeding and hemorrhagic stroke). Despite these observations, antithrombotic treatment strategies in East Asian patients are mainly based on the American or European guidelines that are derived from randomized, controlled trials including mostly Caucasians...

The paradoxical role of ER stress in malignant diseases is only just being unraveled and remains incompletely understood. A particular challenge is the complex interplay between spaciotemporal and locoregional microenvironmental constraints in solid tumors and stress responses upon treatment; thus, the potential for new combinatorial therapeutic options to foster the coincidence of ER stress-related deadly events is likely to be underestimated. Without claiming this review to be complete, we present a comprehensive overview of the signaling mechanisms associated with the unfolded protein response (UPR) and the molecular link to cell survival and death mechanisms...

BACKGROUND: The impact of overweight and obesity on outcomes in "real world" patients with atrial fibrillation (AF) is not fully defined. Second, sex differences in AF outcomes may also exist. METHODS AND RESULTS: The aim was to investigate outcomes at 1-year follow-up for AF patients enrolled in the EORP-AF Registry, according to BMI (kg/m2 ), comparing patients with normal BMI (18.5 to < 25 kg/m2), overweight (25 to < 30 kg/m2 ) and obesity (≥30 kg/m2 ), in relation to sex differences...

Background: Sexual problems are common among the middle-aged women; however, there is no deep understanding of sexuality in midlife. The current study aimed to investigate Iranian women's attitudes and experiences about sexual life changes in midlife. Methods: This is a descriptive qualitative study. Seventeen women aged 40 -65 years old were purposively selected from urban health centers in Gorgan, Iran, in 2015. Face-to-face, semi-structured and in-depth interviews were conducted for data collection until data saturation was attained...

Environmental fluctuations, such as changing conditions and variable nutrient availability, are an unavoidable component of the dynamics of virtually all populations. They affect populations in ways that are often difficult to predict and sometimes lead to paradoxical outcomes. Here, we present a general analytical approach to examine how populations respond to fluctuations. We show that there exist general explicit conditions that determine to what extent fluctuations propagate to the variability of the responses and how they change the behavior of the system, including whether they promote proliferation or death and whether they facilitate coexistence or exclusion of competing species...

Epidemiologists commonly use the risk ratio to summarize the relationship between a binary covariate and outcome, even when outcomes may be dependent. Investigations of transmissible diseases in clusters-households, villages or small groups-often report risk ratios. Epidemiologists have warned that risk ratios may be misleading when outcomes are contagious, but the nature of this error is poorly understood. In this study, we assess the meaning of the risk ratio when outcomes are contagious. We provide a mathematical definition of infectious disease transmission within clusters, based on the canonical stochastic susceptible-infective model...

Resistance to the RAF inhibitor vemurafenib arises commonly in melanomas driven by the activated BRAF oncogene. Here we report antitumor properties of RAF709, a novel ATP-competitive kinase inhibitor with high potency and selectivity against RAF kinases. RAF709 exhibited a mode of RAF inhibition distinct from RAF monomer inhibitors such as vemurafenib, showing equal activity against both RAF monomers and dimers. As a result, RAF709 inhibited MAPK signaling activity in tumor models harboring either BRAFV600 alterations or mutant N- and KRAS-driven signaling, with minimal paradoxical activation of wild-type RAF...

We are grateful to Dr. Baker and colleagues for their interest in our recent work and agree with their interpretation of our study that investigated weight change in the early rheumatoid arthritis (RA) period among women diagnosed with RA and matched comparators. As they point out, any weight loss and severe weight loss in the early RA or matched index period were both more common among those with RA than matched comparators. The authors suggest that this increased frequency of weight loss may exacerbate the obesity paradox for mortality among patients with RA...
