BACKGROUND: Consumption of unrecorded alcohol (alcohol that is not taxed and reflected in official statistics, but consumed as a beverage) has been identified as one of the main contributors to alcohol-attributable premature mortality in Russia. The problem was highlighted by a recent a mass poisoning with surrogate alcohol occurred in the Siberian city of Irkutsk. METHODS: Based on key publications and legislative documents, a narrative review was undertaken about alcohol-related harm reduction policies in Russia for the period between 2005 and 2017, as well as the impact of these policies on the recorded and unrecorded alcohol consumption and alcohol market...

BACKGROUND: Neuromodulation devices have the potential to transform modern day treatments for patients with medicine-resistant neurological disease. For instance, the NeuroPace System (NeuroPace Inc, Mountain View, California) is a Food and Drug Administration (FDA)-approved device developed for closed-loop direct brain neurostimulation in the setting of drug-resistant focal epilepsy. However, current methods require placement either above or below the skull in nonanatomic locations. This type of positioning has several drawbacks including visible deformities and scalp pressure from underneath leading to eventual wound healing difficulties, micromotion of hardware with infection, and extrusion leading to premature explantation...

Approximately 35 million people worldwide suffer from heterozygous familial hypercholesterolaemia (HeFH), a condition characterized by genetically determined life-long elevation of plasma low-density lipoprotein cholesterol (LDL-C). One in three of these patients also inherit an elevated plasma concentration of lipoprotein (a) [Lp(a)], a lipoprotein particle with atherogenic, inflammatory and prothrombotic properties. Accordingly, the combination of high plasma LDL-C and Lp(a) can markedly accelerate premature atherosclerotic cardiovascular disease (ASCVD)...

Context: NaPi-IIa, encoded by SLC34A1 is a key phosphate transporter in the mammalian proximal tubule, and plays a cardinal role in renal phosphate handling. NaPi-IIa impairment has been linked to various overlapping clinical syndromes, including hypophosphatemic nephrolithiasis with osteoporosis, renal Fanconi's syndrome with chronic kidney disease, and most recently, with idiopathic infantile hypercalcemia and nephrocalcinosis. Objectives: We studied the molecular basis of idiopathic infantile hypercalcemia with partial proximal tubulopathy in two apparently unrelated patients of Israeli and Turkish descent...

The major goal of this review is to summarize recent exciting findings that have been published within the past 10 years that, to our knowledge, have not been presented in detail in previous reviews and that may impact altered follicular development in polycystic ovarian syndrome (PCOS) and premature ovarian failure (POF) in women. Specifically, we will cover 1) mouse models that have led to discovery of the derivation of two precursor populations of theca cells in the embryonic gonad, 2) the key roles of the oocyte-derived factor GDF9 on the hedgehog (HH) signaling pathway and theca cell functions and 3) the impact of the HH pathway on both the specification of theca endocrine cells and theca fibroblast and smooth muscle cells in developing follicles...

Summary: Biological models contain many parameters whose values are difficult to measure directly via experimentation and therefore require calibration against experimental data. Markov chain Monte Carlo (MCMC) methods are suitable to estimate multivariate posterior model parameter distributions, but these methods may exhibit slow or premature convergence in high-dimensional search spaces. Here, we present PyDREAM, a Python implementation of the (Multiple-Try) Differential Evolution Adaptive Metropolis (DREAM(ZS)) algorithm developed by Vrugt and ter Braak (2008) and Laloy and Vrugt (2012)...

<p>Aging is a complex process influenced by both extrinsic and intrinsic factors. Premature signs of aging due to cumulative UV exposure represent a major concern of the cosmetic patient. Skin of color is less susceptible to photodamage and thus signs of aging are less pronounced and occur later than in Caucasians. Understanding structural and functional differences among different racial/ethnic groups is important to achieve favorable treatment outcomes when addressing aging concerns.</p> <p><em<J Drugs Dermatol...

AIM: This study aimed to study the effects of intratracheal instillation of budesonide on lung maturity of premature fetal rabbits. The developmental pattern of pulmonary alveoli in rabbits is similar to that in humans. METHOD: Fetal rabbits were taken out from female rabbits on the 28th day of pregnancy (full term = 31 days) by cesarean section (c-section). The fetal rabbits were divided into four groups: control (normal saline, NS), budesonide (budesonide, BUD), calf pulmonary surfactant for injection (pulmonary surfactant, PS), and calf pulmonary surfactant + budesonide for injection (pulmonary surfactant + budesonide, PS + BUD)...

Background Antibody drug conjugates (ADCs) utilize a monoclonal antibody to deliver a cytotoxic payload specifically to tumor cells, limiting exposure to healthy tissues. Major clinical toxicities of ADCs include hematologic, hepatic, neurologic, and ophthalmic events, which are often dose-limiting. These events may be off-target effects caused by premature release of payload in circulation. A meta-analysis was performed to summarize key clinical safety data for ADCs by payload, and data permitting, establish a dose-response model for toxicity incidence as a function of payload, dose/regimen, and cancer type...

AIM: Iatrogenic premature rupture of membrane (PROM) is one of the major complications related to fetoscopic laser photocoagulation (FLP) for twin-twin transfusion syndrome (TTTS). However, amniotic fluid leakage (AFL) sometimes spontaneously disappears. This study evaluated the incidence and clinical characteristics of transient AFL after FLP. METHODS: We retrospectively reviewed pregnancies that underwent FLP for TTTS at a single center. Patients with apparent AFL within 2 weeks after FLP were divided into two groups: transient AFL, defined by the disappearance of fluid leakage within a week; and PROM, if AFL persisted continuously for more than a week or premature birth occurred, including miscarriage, within a week of the first symptom of AFL...

Retinopathy of prematurity (ROP) is a vascular disorder of the developing retina in preterm infants and is a leading cause of childhood blindness. Perinatal infection plays a pathogenic role in ROP. Probiotic supplementation reduces the risk of late onset sepsis (LOS) in preterm infants but it remains to be determined whether this reduction translates into a reduction of other complications. We conducted a systematic review and meta-analysis to evaluate the possible role of probiotics in altering the risk of ROP...

MCPH1 gene, mutated in primary microcephaly, regulates cell progression into mitosis. While this role has been extensively investigated in the context of DNA damage, its function during unperturbed cell cycles has been given less attention. Here we have analyzed the dynamics of chromosome condensation and cell cycle progression in MCPH1 deficient cells under undamaging conditions. Our study demonstrates that chromosome condensation is uncoupled from cell cycle progression when MCPH1 function is lacking, resulting in cells that prematurely condense their chromosomes during mid G2-phase and delay decondensation at the completion of mitosis...

Secondary batteries based on earth-abundant sodium metal anodes are desirable for both stationary and portable electrical energy storage. Room-temperature sodium metal batteries are impractical today because morphological instability during recharge drives rough, dendritic electrodeposition. Chemical instability of liquid electrolytes also leads to premature cell failure as a result of parasitic reactions with the anode. Here we use joint density-functional theoretical analysis to show that the surface diffusion barrier for sodium ion transport is a sensitive function of the chemistry of solid-electrolyte interphase...

BACKGROUND: Lung epithelial cells express surfactant protein D (SP-D), a calcium-dependent lectin that plays an important role in antibody-independent pulmonary host defense. Previous studies have shown that it is found in the peripheral circulation in patients with pulmonary disease, likely because of translocation into the blood when lung epithelial barriers are disrupted by inflammation or acute injury. In adults, serum SP-D levels are biomarkers for the progression and severity of chronic lung disease...
