Status epilepticus, a condition with prolonged or repeated seizures, is a common neurological emergency with significant morbidity and mortality. This text outlines the treatment and initial work-up for convulsive and non-convulsive status epilepticus in adults and children. The most serious form is convulsive (tonic-clonic) status epilepticus, which requires rapid treatment and work-up. Bensodiazepines are the preferred initial treatment, while antiepileptic drugs and anesthetics are added if seizures continue...

TMPRSS2/ERG is the most common type of gene fusions found in human prostate cancer. There are two important features of TMPRSS2/ERG fusions. One is that these gene fusions lead to ectopic expression of ERG, an ETS family transcription factor, in prostate epithelial cells from the 5' control region of an androgen/estrogen dual-responsive gene, TMPRSS2; the other is that ~60% of these fusions are generated via intrachromosomal deletion of the interstitial region between TMPRSS2 and ERG. To recapitulate these important aspects of TMPRSS2/ERG fusions, we generated several TMPRSS2/ERG knockin mouse models based on the endogenous Tmprss2 locus...

Flexible 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)-oxidized nanofibrillated cellulose (ONFC) films with long afterglow luminescence containing modified SrAl₂O₄: Eu2+ , Dy3+ (SAOED) phosphors were fabricated by a template method. Tetraethyl orthosilicate (TEOS) and (3-aminopropyl) trimethoxy-silane (APTMS) were employed cooperatively to improve the water resistance and compatibility of the SAOED particles in the ONFC suspension. The structure and morphology after modification evidenced the formation of a superior SiO₂ layer and coarse amino-compounds on the surface of the phosphors...

While many university students take science courses in multiple disciplines, little is known about how they perceive common concepts from different disciplinary perspectives. Structure-property and structure-function relationships have long been considered important explanatory concepts in the disciplines of chemistry and biology, respectively. Fourteen university students concurrently enrolled in introductory chemistry and biology courses were interviewed to explore their perceptions regarding 1) the meaning of structure, properties, and function; 2) the presentation of these concepts in their courses; and 3) how these concepts might be related...

Instructor-generated videos have become a popular way to engage students with material before a class, yet this is a relatively unexplored area of research. There is support for the use of videos in which instructors tutor students, but few studies have been conducted within the context of a classroom. In this study, conducted in a large-enrollment college physiology course, we used a randomized crossover design to compare the impact of two types of instructor-generated videos that students watched as part of their preclass assignments...

Bartter syndromes (BS) types 1-5 are rare salt-losing tubulopathies presenting with overlapping clinical phenotypes including marked salt wasting and hypokalemia leading to polyuria, polydipsia, volume contraction, muscle weakness and growth retardation. These diseases are due to an impairment of sodium, potassium, chloride reabsorption caused by mutations in genes encoding for ion channel or transporters expressed in specific nephron tubule segments. Particularly, BS type 3 is a clinically heterogeneous form caused by mutations in CLCNKB gene which encodes the ClC-Kb chloride channel involved in NaCl reabsorption in the renal tubule...

The nucleosome remodeling complex RSC functions throughout the yeast genome to set the positions of -1 and +1 nucleosomes and thereby determines the widths of nucleosome-depleted regions (NDRs). The related complex SWI/SNF participates in nucleosome remodeling/eviction and promoter activation at certain yeast genes, including those activated by transcription factor Gcn4, but did not appear to function broadly in establishing NDRs. By analyzing the large cohort of Gcn4-induced genes in mutants lacking the catalytic subunits of SWI/SNF or RSC, we uncovered cooperation between these remodelers in evicting nucleosomes from different locations in the promoter and repositioning the +1 nucleosome downstream to produce wider NDRs-highly depleted of nucleosomes-during transcriptional activation...

How producers of public goods persist in microbial communities is a major question in evolutionary biology. Cooperation is evolutionarily unstable, since cheating strains can reproduce quicker and take over. Spatial structure has been shown to be a robust mechanism for the evolution of cooperation. Here we study how spatial assortment might emerge from native dynamics and show that fluid flow shear promotes cooperative behavior. Social structures arise naturally from our advection-diffusion-reaction model as self-reproducing Turing patterns...

REVIEW
Patrick Lhomme, Heather M Hines
In eusocial insects, the high cost of altruistic cooperation between colony members has favoured the evolution of cheaters that exploit social services of other species. In the most extreme forms of insect social parasitism, which has evolved multiple times across most social lineages, obligately parasitic species invade the nests of social species and manipulate the workforce of their hosts to rear their own reproductive offspring. As alien species that have lost their own sociality, these social parasites still face social challenges to infiltrate and control their hosts, thus providing independent replicates for understanding the mechanisms essential to social dominance...

Infections are a major cause of death in patients with multiple myeloma. A post hoc analysis of the phase 3 FIRST trial was conducted to characterize treatment-emergent (TE) infections and study risk factors for TE grade ≥ 3 infection. The number of TE infections/month was highest during the first 4 months of treatment (defined as early infection). Of 1613 treated patients, 340 (21.1%) experienced TE grade ≥ 3 infections in the first 18 months and 56.2% of these patients experienced their first grade ≥ 3 infection in the first 4 months...

The N 6 -methylation of internal adenosines (m6A) in mRNA has been quantified and localized throughout the transcriptome. However, the physiological significance of m6A in most highly methylated mRNAs is unknown. It was demonstrated previously that the circadian clock, based on transcription-translation negative feedback loops, is sensitive to the general inhibition of m6A. Here, we show that the Casein Kinase 1 Delta mRNA ( Ck1δ ), coding for a critical kinase in the control of circadian rhythms, cellular growth, and survival, is negatively regulated by m6A...

Among the factors that may lead to differences in resource use among closely related species, body size and morphology have been traditionally considered to play a role in community assembly. Here we argue that for animals that live and forage in groups, level of sociality, reflecting differences in group size and cooperative tendencies, can be an additional and powerful dimension separating species in niche space. We compare 50+ communities of the social spider genus Anelosimus across the Americas against a null model that accounts for known effects of biotic and abiotic factors on the distribution of social systems in the genus...

A central tenet of biology is that globular proteins have a unique 3D structure under physiological conditions. Recent work has challenged this notion by demonstrating that some proteins switch folds, a process that involves remodeling of secondary structure in response to a few mutations (evolved fold switchers) or cellular stimuli (extant fold switchers). To date, extant fold switchers have been viewed as rare byproducts of evolution, but their frequency has been neither quantified nor estimated. By systematically and exhaustively searching the Protein Data Bank (PDB), we found ∼100 extant fold-switching proteins...

Iliocaval thrombosis, or thrombosis of the inferior vena cava and iliac veins, is associated with significant morbidity in the form of limb-threatening compromise from phlegmasia cerulean dolens, development of post-thrombotic syndrome, and death secondary to pulmonary embolism. Endovascular iliocaval reconstruction is an effective treatment for iliocaval thrombosis with high levels of technical success, favorable clinical outcomes and stent patency rates, and few complications. It is often able to relieve the debilitating symptoms experienced by affected patients and is a viable option for patients who fail conservative management...

Epoxidized soybean oil (ESO) was employed as a novel penetrant cooperating with a conventional rejuvenator (CR) for the recycling of reclaimed asphalt pavement (RAP). The influence of ESO on the diffusibility and the regenerating effects of CR on RAP were investigated. The diffusibility testing result shows that the diffusibility of CR is enhanced by the addition of ESO because the epoxy group in ESO can facilitate asphaltene dispersion due to its high polarity, which simultaneously reduces the viscosity and improves the fluidity of aged bitumen so as to allow diffusion of the rejuvenator into the aged bitumen...

OBJECTIVE: Introduction: One of the main features of orthodontic treatment is the cooperation of the doctor with the patient. Active growth of a child's organism at the age from 6 to 12 has not only physiological but also psychological aspects of development. Motivation for orthodontic treatment is absent during mixed dentition. Only taking into account the somato-psychological status and the psycho-emotional condition of the patient during the orthodontic treatment allows to choose an optimal treatment option and to predict its effectiveness...
