Haemophagocytic lymphohistiocytosis (HLH) is a rare, potentially fatal, haematological disorder, which can be clinically challenging to diagnose and manage. We report a case of HLH in a previously healthy 33-year-old primigravida. The patient presented at 22 weeks gestation with dyspnoea, abdominal pain, anaemia, thrombocytopenia and elevated liver enzymes suggestive of HELLP syndrome.HELLP, a syndrome characterised by haemolysis, elevated liver enzymes and low platelets is considered a severe form of pre-eclampsia...

Growth of bacterial and archaeal species capable of interspecies electron exchange was stimulated by addition of conductive materials (carbon cloth or granular activated carbon (GAC)) to anaerobic digesters treating dog food (a substitute for the dry-organic fraction of municipal solid waste (OFMSW)). Methane production (772-1428mmol vs <80mmol), volatile solids removal (78%-81% vs 54%-64%) and COD removal efficiencies (∼80% vs 20%-30%) were all significantly higher in reactors amended with GAC or carbon cloth than controls...

OBJECTIVE: Progestin-only contraceptives induce abnormal uterine bleeding, accompanied by pro-thrombin leakage from dilated endometrial microvessels and increased thrombin generation by human endometrial stromal cell (HESC)-expressed tissue factor. Initial studies of the thrombin-treated HESC secretome identified elevated levels of cleaved chondroitin sulfate proteoglycan 4 (CSPG4), impairing pericyte-endothelial interactions. Thus, we investigated direct and CSPG4-mediated effects of thrombin in eliciting abnormal uterine bleeding by disrupting endometrial angiogenesis...

A worsening epidemic of diabetes and its precursor, metabolic syndrome (MetS) is engulfing America. A healthy individual, with proper glucose regulation has an ability to switch between burning fat and carbohydrates. It has been suggested that signaling errors within this homeostatic system, characterized by impaired switching of substrate oxidation from glucose to fat in response to insulin, can contribute to the etiology of metabolic syndrome and occurs before the development of type II diabetes. Glucose regulation with restored insulin sensitivity facilitated through clinically regulated, benign dietary ketosis (BDK), may significantly reduce, regulate and reverse the adverse pathologies common to MetS and obesity...

Few individuals living with mental disorders around the globe have access to mental health care, yet most have access to a mobile phone. Digital technology holds promise for improving access to, and quality of, mental health care. We reviewed evidence on the use of mobile, online, and other remote technologies for treatment and prevention of mental disorders in low-income and middle-income countries. Of the 49 studies identified, most were preliminary evaluations of feasibility and acceptability. The findings were promising, showing the potential effectiveness of online, text-messaging, and telephone support interventions...

ATR, a protein kinase in the PIKK family, plays a critical role in the cell DNA-damage response and is an attractive anticancer drug target. Several potent and selective inhibitors of ATR have been reported showing significant antitumor efficacy, with most advanced ones entering clinical trials. However, due to the absence of an experimental ATR structure, the determinants contributing to ATR inhibitors' potency and specificity are not well understood. Here we present the mutations in the ATP-binding site of PI3Kα to progressively transform the pocket to mimic that of ATR...

Due to a large and growing collection of genomic and experimental resources, Brachypodium distachyon has emerged as a powerful experimental model for the grasses. To add to these resources we sequenced 21,165 T-DNA lines, 15,569 of which were produced in this study. This increased the number of unique insertion sites in the T-DNA collection by 21,078 bringing the overall total to 26,112. Thirty seven percent (9,754) of these insertion sites are within genes (including UTRs and introns) and 28% (7,217) are within 500 bp of a gene...

Septate junctions (SJs) regulate paracellular permeability across invertebrate epithelia. However, little is known about the function of SJ proteins in aquatic invertebrates. In this study, a role for the transmembrane SJ protein gliotactin (Gli) in the osmoregulatory strategies of larval mosquito (Aedes aegypti) was examined. Differences in gli transcript abundance were observed between the midgut, Malpighian tubules (MT), hindgut and anal papillae (AP) of A. aegypti, which are epithelia that participate in larval mosquito osmoregulation...

Species in the extremely thermophilic genus Caldicellulosiruptor can degrade unpretreated plant biomass through the action of multi-modular glycoside hydrolases. To date, most focus with these bacteria has been on hydrolysis of glucans and xylans, while biodegradation mechanism for arabinose-based polysaccharides remains unclear. Here, putative α-L-arabinofuranosidases (AbFs) were identified in Caldicellulosiruptor species by homology to less thermophilic versions of these enzymes. From this screen, an extracellular XynF was determined to be a key factor in hydrolyzing α-1,2-, α-1,3-, and α-1,5-L-arabinofuranosyl residues of arabinose-based polysaccharides...

To investigate gender stereotypes, demonstrated engineering aptitude, and attitudes, children (N=105) solved an engineering problem using either pastel-colored or primary-colored materials. Participants also evaluated the acceptability of denial of access to engineering materials based on gender and counter-stereotypic preferences (i.e., a boy who prefers pastel-colored materials). Whereas material color was not related to differences in female participants' performance, younger boys assigned to pastel materials demonstrated lower engineering aptitude than did other participants...

This guidance document describes the specific issues involved in dental multilayer ceramic systems. The material interactions with regard to specific thermal and mechanical properties are reviewed and the characteristics of dental tooth-shaped processing parameters (sintering, geometry, thickness ratio, etc.) are discussed. Several techniques for the measurement of bond quality and residual stresses are presented with a detailed discussion of advantages and disadvantages. In essence no single technique is able to describe adequately the all-ceramic interface...

The obesity epidemic has been the target of several studies to understand its etiology. The pathophysiological processes that take to obesity generally relate to the rupture of energy balance. This imbalance can result from environmental and/or endogenous events. Among the endogenous events, the hypothalamic-pituitary-adrenal axis, which promotes stress response via glucocorticoid activity, is considered a modulator of energy balance. However, it remains controversial whether the increase in plasma levels of glucocorticoids results in a positive or negative energy balance...

It is unclear how old age affects the neuronal mechanisms of motor learning. We reviewed the neuronal mechanisms of how healthy old and young adults acquire motor skills as assessed with transcranial magnetic stimulation. Quantitative meta-analyses of 11 studies, involving ballistic and visuomotor tasks performed by upper extremity muscles in 132 healthy old and 128 young adults, revealed that the motor practice-induced increase in corticospinal excitability (CSE) is task-dependent but not age-dependent, with an increase in CSE in both age groups after visuomotor but not ballistic training...

Epigenetic modifications result in dynamic shifts between transcriptionally active and suppressed states. The potentially reversible nature of epigenetic changes underlies the concept of epigenetic therapy, which serves to reprogram cancer cells as opposed to inducing cytotoxicity that occurs with standard chemotherapeutics. There are numerous enzymes involved in epigenetic changes and each can be potentially targetable. Although many investigations have evaluated the clinical potential of the various epigenetic therapies, currently only histone deacetylase inhibitors and DNA methyltransferase inhibitors are approved for use in specific hematologic malignancies...
