Lipid droplets (LDs) are regulated neutral lipid storage organelles having a central role in numerous cellular processes as well as in various pathologies such as metabolic disorders, immune responses and during pathogen infection. Several viruses were found to use the interface between the endoplasmic reticulum (ER) and LDs as the site for replication and assembly. Due to the growing significance of LDs, extensive efforts are made to study the mechanism and the dynamics of their formation and life history and how are these diverted or modified by pathogens...

Sulfur dioxide (SO₂) is a toxic gas and air pollutant. The toxic effects of SO₂ have been extensively studied. Oxidative damage due to SO2 can occur in multiple organs. Inhaled SO₂ can also cause chromosomal aberrations, DNA damage and gene mutations in mammals. However, SO₂ can also be generated from the sulfur-containing amino acid, L-cysteine. Recent studies have shown that SO₂ has a vasorelaxant effect, and ameliorates pulmonary hypertension and vascular remodeling. SO₂ can also reduce lung injury and myocardial injury in rats...

Both purpura fulminans and toxic epidermal necrolysis (TEN) are rare and life-threatening disorders with a high mortality. We present a case of suspected rapidly progressive, severe pneumococcal sepsis-induced purpura fulminans complicated by multiple organ failure, severe epidermolysis and cutaneous necrosis. We show the diagnostic challenge to differentiate between purpura fulminans and TEN, as the extensive epidermolysis in purpura fulminans may mimic TEN and we highlight the additional value of repeated skin biopsies and 16S rRNA gene sequencing...

The objective of this study was to evaluate the effectiveness of individual cognitive behavioural therapy (CBT) for post-stroke fatigue and sleep disturbance compared to treatment as usual (TAU). In a parallel two-group pilot randomised controlled trial of 15 participants, nine were allocated to eight weekly sessions of adapted CBT and six continued usual care rehabilitation. The primary outcome was the Fatigue Severity Scale (FSS-7) at two and four months from baseline. Secondary outcomes included measures of sleep, mood and quality of life...

Currently, nanoparticles are widely used in biomedicine and industry. CuO nanoparticles (CuO-NPs) are versatile materials in our daily life and their toxicity has drawn extensive attention. In this study, we concentrate on the effect of CuO-NPs on early zebrafish development. The results reveal that CuO-NPs can induce abnormal phenotypes of a smaller head and eyes and delayed epiboly. The gene expression pattern shows that CuO-NPs spatially narrow the expression of dorsal genes chordin and goosecoid and alter the expression of dlx3, ntl and hgg which are related to the cell migration of gastrulation...

BACKGROUND: Following at least three months of anticoagulation therapy after a first unprovoked Venous Thromboembolism (VTE), there is uncertainty about the duration of therapy. Further anticoagulation therapy reduces the risk of having a potentially fatal recurrent VTE but at the expense of a higher risk of bleeding which can also be fatal. OBJECTIVE: An economic evaluation sought to estimate the long-term cost-effectiveness of using a decision rule for restarting anticoagulation therapy versus no extension of therapy in patients based on their risk of a further unprovoked VTE...

Sarangam Majumdar, Sukla Pal
Bacteria are far more intelligent than we can think of. They adopt different survival strategies to make their life comfortable. Researches on bacterial communication to date suggest that bacteria can communicate with each other using chemical signaling molecules as well as using ion channel mediated electrical signaling. Though in past few decades the scopes of chemical signaling have been investigated extensively, those of electrical signaling have received less attention. In this article, we present a novel perspective on time-sharing behavior, which maintains the biofilm growth under reduced nutrient supply between two distant biofilms through electrical signaling based on the experimental evidence reported by Liu et al...

BACKGROUND: Social inequality trends in life expectancy are not informative as to changes in social disparity in the age-at-death distribution. The purpose of the study was to investigate social differentials in trends and patterns of adult mortality in Denmark. METHODS: Register data on income and mortality from 1986 to 2014 were used to investigate trends in life expectancy, life disparity and the threshold age that separates 'premature' and 'late' deaths. Mortality compression was quantified and compared between income quartiles...

Background: Whether antenatal and neonatal vitamin D status have clinical relevance in fracture prevention has not been examined extensively, although observational studies indicate that fetal life may be a sensitive period in relation to bone growth and mineralization during childhood.Objective: We examined whether 25-hydroxyvitamin D3 [25(OH)D3] concentrations in stored neonatal dried blood spot (DBS) samples are associated with pediatric fracture risk. We hypothesized that in particular, low neonatal vitamin D status may be a risk factor for fracture incidence among children...

In contrast to the narrowing of options in academic careers, the bioscience industry offers robust employment opportunities for STEM-trained workers, especially those who display both scientific and business talent. Unfortunately, traditional science programs typically lack curricular features that develop this type of worker. The North Carolina State University Master of Microbial Biotechnology (MMB) program facilitates industry-specific experiential learning to fill this training gap. Similar programs often rely on a single industry internship to provide students relevant work experience, but completion of one internship might not suffice to position students for employment in a highly competitive job market...

Dracontomelon duperreanum, the most representative species of the family Anacardiaceae, is an important multipurpose tree in China and Vietnam. However, no genetic diversity studies have been reported on this species. In this study, we identified 11 microsatellite markers for D. duperreanum by using the restriction-site-associated DNA sequencing (RAD-seq) method and examined their polymorphisms in 22 samples obtained from the South China Botanical Garden, South China. We could detect only two or three alleles for each microsatellite marker...

Erythropoietin (EPO) is one of the main treatments for anaemic patients, greatly improving their quality of life. In this study, biosimilars Binocrit and a development product, called here CIGB-EPO, were compared to the originator product, Eprex. All three are epoetin alpha products, reputed to have similar glycosylation profiles. The quality, safety and efficacy of this biotherapeutic depend on the following glycosylation critical quality attributes (GCQAs): sialylation, N-glycolyl-neuraminic acid (Neu5Gc) content, branching, N-acetyl-lactosamine (LacNAc) extensions and, arguably, O-acetylation pattern...

Penile calciphylaxis is a rare phenomenon of penile necrosis observed in patients with hemodialysis-dependent end-stage renal failure. Multiple treatments have been proposed including conservative management, surgical debridement and penectomy; yet, the prognosis remains extremely poor. Here, we describe a patient with protracted resolution of dry gangrene of the glans, which failed conservative management of wound care and pain management. Radiological studies revealed extensive calcification of abdominal aorta and branching vessels including the penile arteries...

Heart failure (HF) is a pressing health concern as the expense of hospitalization financially burdens the health care system. Hemodynamic monitoring has the potential to detect increases in intracardiac filling pressures weeks before clinical deterioration; hence, preliminary findings of volume overload with the use of these devices may prevent the progression of disease and lead to a reduction in HF-associated hospitalizations. We extensively searched PubMed, Ovid SP, Embase, and Cochrane databases to identify all the possible studies that assess the effect of hemodynamic monitoring on hospitalizations in HF patients...

ETHNOPHARMACOLOGICAL RELEVANCE: Medicinal diets have a history of more than 2000 years. Locally referred to as yaoshan (Chinese: ), a medicinal diet is understood in China as a dietary product that combines herbs and food with the purpose of preventing and treating diseases or improving health under the guidance of traditional Chinese medicine theory. Medicinal diets are used in Chinese people's daily life and in specialized restaurants. Hundreds of Chinese materia medica (CMM) are used in medicinal diets; however, a comprehensive evaluation of medicinal diets is lacking...

Chronic respiratory failure due to chronic obstructive pulmonary disease (COPD) is an increasing problem worldwide. Many patients with severe COPD develop hypoxemic respiratory failure during the natural progression of disease. Long-term oxygen therapy (LTOT) is a well-established supportive treatment for COPD and has been shown to improve survival in patients who develop chronic hypoxemic respiratory failure. The degree of hypoxemia is severe when partial pressure of oxygen in arterial blood (PaO2) is ≤55 mmHg and moderate if PaO2 is between 56 and 69 mmHg...

Tracheomalacia refers to a softness of the tracheal cartilage that makes the airway more susceptible to collapse. In contrast to milder cases where conservative therapy is preferred, severe tracheomalacia is often a life threatening condition requiring more aggressive management. For children with this condition, a variety of treatment options are available. To our knowledge, this is the first report of home high-flow nasal cannula as an alternative therapy to continuous positive airway pressure (CPAP) and surgical procedures in a pediatric patient with severe extensive tracheomalacia...
