We aim to delineate the genetic and clinical features of SCN8A developmental and epileptic encephalopathy.

In biological experiments, comprehensive experimental metadata tracking - which comprises experiment, reagent, and protocol annotation with controlled vocabulary from established ontologies - remains a challenge, especially when the experiment involves multiple laboratory scientists who execute different steps of the protocol. Here we describe Annot, a novel web application designed to provide a flexible solution for this task.

Genomic selection has the potential to increase genetic gains by using molecular markers as predictors of breeding values of individuals. This study evaluated the accuracy of predictions for grain yield, heading date, plant height, and yield components in soft red winter wheat under different prediction scenarios. Response to selection for grain yield was also compared across different selection strategies- phenotypic, marker-based, genomic, combination of phenotypic and genomic, and random selections.

Cannabis is commonly used for its medical properties. In particular, cannabis is purported to have beneficial effects on a wide range of neuropsychiatric conditions. Studies assessing mental health in cannabis dispensary users typically evaluate symptoms using self-report check lists, which provide limited information about symptom severity, and whether subjects meet criteria for a psychiatric diagnosis. There is, therefore, a need for studies which assess mental health in dispensary users with standardized and well validated scientific instruments, such as those used in clinical drug trials.

The period from birth to two years is the "critical window" for achieving optimal growth and development. An inadequate quality and quantities of complementary foods, poor child-feeding practices and infection negatively impact the growth of under-twos. Approximately one-third of under-fives in developing countries are stunted; many are also micronutrient deficient. An estimated 6% of mortalities among under-fives can be prevented by ensuring optimal complementary feeding. The objective of the study was to assess the ability of a 12-month integrated nutrition intervention to improve the nutritional status (length-for-age Z-score) of 6 to 12-month-old children in rural Bangladesh.

The lack of predictive biomarkers or test systems contributes to high failure rates of systemic therapy in metastasized colorectal carcinoma, accounting for a still unfavorable prognosis. Here, we present an ex vivo functional assay to measure drug-response based on a tissue slice culture approach.

The PAOX1-based expression system is the most widely used for producing recombinant proteins in the methylotrophic yeast Pichia pastoris (Komagataella phaffii). Despite relevant recent advances in regulation of the methanol utilization (MUT) pathway have been made, the role of specific growth rate (µ) in AOX1 regulation remains unknown, and therefore, its impact on protein production kinetics is still unclear.

There is an increasing recognition that health intervention research requires methods and approaches that can engage with the complexity of systems, interventions, and the relations between systems and interventions. One approach which shows promise to this end is qualitative comparative analysis (QCA), which examines casual complexity across a medium to large number of cases (between 10 and 60+), whilst also being able to generalise across those cases. Increasingly, QCA is being adopted in public health intervention research. However, there is a limited understanding of how it is being adopted. This systematic review will address this gap, examining how it is being used to understand complex causation; for what settings, populations and interventions; and with which datasets to describe cases.

Current genomics methods are designed to handle tens to thousands of samples but will need to scale to millions to match the pace of data and hypothesis generation in biomedical science. Here, we show that high efficiency at low cost can be achieved by leveraging general-purpose libraries for computing using graphics processing units (GPUs), such as PyTorch and TensorFlow. We demonstrate > 200-fold decreases in runtime and ~ 5-10-fold reductions in cost relative to CPUs. We anticipate that the accessibility of these libraries will lead to a widespread adoption of GPUs in computational genomics.

Increasingly, pragmatic randomised controlled trials are being used to evaluate surgical interventions, although they present particular difficulties in regards to recruitment and retention.

The glucocorticoid receptor (NR3C1, GR) is frequently downregulated in breast tumors, and evidence suggests it acts as a tumor suppressor in estrogen receptor-positive (ER+) breast cancer. We previously found that methylation of the GR promoter CpG island represses gene expression and occurs in ER+ breast tumors. In this study, the prognostic and predictive value of GR methylation was examined in ER+ patients from the CCTG MA.12 clinical trial of tamoxifen versus placebo in women with early breast cancer.

β-arrestin-2(Arr2) functions as an anti-apoptotic factor and affects cell proliferation, but its downstream molecular pathway in endometrial carcinoma (EC) is still unclear. This study aimed to investigate the effects of the stable overexpression of Arr2 on the proliferation and apoptosis of human EC heterotransplants and the expression of associated molecules, including Toll-like receptor 2(TLR2), serine-threonine kinase Akt (Akt), glycogen synthase kinase-3β(GSK3β) and some typical inflammatory cytokines such as NF-κB p56, TNF-α and IL-6 & IL-8.

Women with ovarian cancer can present with a variety of symptoms and signs, and an increasing range of tests are available for their investigation. A number of international guidelines provide advice for the initial assessment of possible ovarian cancer in symptomatic women. We systematically identified and reviewed the consistency and quality of these documents.

Present demographic trends show a considerable rise in elderly populations with aging disorders, such as dementia. The current article focused on the exploitation of e-learning as an informal support for caregivers of people with dementia and considered its benefits and limitations to provide proper and relevant care for this target group of people as well as maintain the quality of life of their caregivers.

Clinical cases of Erysipelothrix rhusiopathiae, a zoonotic gram-positive bacterium, have been reported in many ruminant species, including in cattle, deer, moose and muskoxen. Fatal cases have been repeatedly reported in cattle over the years but to date there is only one Japanese study investigating the seroprevalence of this bacterium in cattle using the growth agglutination test (GAT). This technique is subjective, time-consuming, expensive and hazardous compared to modern serological tests such as enzyme-linked immunosorbent assays (ELISA) or the newly developed fluorescent microbead-based immunoassays (FMIA).

The ocean microbiome represents one of the largest microbiomes and produces nearly half of the primary energy on the planet through photosynthesis or chemosynthesis. Using recent advances in marine genomics, we explore new applications of oceanic metagenomes for protein structure and function prediction.

Polymethoxylated flavones (PMFs) are naturally occurring compounds that have biological effects on many cell types. We previously demonstrated that PMFs such as nobiletin potentiate the cytolytic activity of the human leukemic natural killer cell line KHYG-1 and increased level of the cytotoxic protein granzyme B (GrB) and the cytokine interferon-γ (IFN-γ). However, the precise mechanisms by which this occurs remain to be elucidated. In this study, we sought to identify and investigate the function of intracellular primary targets of the PMFs in KHYG-1 cells. Using affinity purification and mass spectrometry, we identified that 3'-hydroxy-4',5,6,7-tetramethoxyflavone (TMF) binds to the nuclear export factors Exportin-1 and -2 (XPO1 and XPO2) as TMF-binding proteins and demonstrated that nobiletin competes with TMF for XPO1 binding, suggesting that nobiletin also binds to XPO1. Treatment of KHYG-1 cells with leptomycin B, a specific XPO1 inhibitor, increased the expression of GrB and IFN-γ but did not potentiate lysis of specific target cells, suggesting that the cargo of XPO1 contributes to the expression of cytolytic genes but that this alone is insufficient to enhance cytolysis. Consistent with this, nobiletin and related PMFs induced the nuclear retention of NF-κB, a transcription factor that promotes GrB and IFN-γ expression. PMFs also induced the nuclear retention of the tumor suppressor protein p53, a known XPO1 cargo protein, resulting in KHYG-1 cell cycle arrest. Collectively, these results suggest that PMFs modulate KHYG-1 function, at least in part, by inhibiting XPO1.

The management of atrial fibrillation and deep venous thrombosis has evolved with the development of direct oral anticoagulants (DOAC), and oral anticoagulant (OAC) might influence the development or clinical course in both ischemic and hemorrhagic stroke. However, detailed data on the differences between the effects of the prior prescription of warfarin and DOAC on the clinical characteristics, neuroradiologic findings, and outcome of stroke are limited.

Disease-causing mutations in many neurodegenerative disorders lead to proteinopathies that trigger endoplasmic reticulum (ER) stress. However, few therapeutic options exist for patients with these diseases. Using an in vitro screening platform to identify compounds that protect human motor neurons from ER stress-mediated degeneration, we discovered that compounds targeting the mitogen-activated protein kinase kinase kinase kinase (MAP4K) family are neuroprotective. The kinase inhibitor URMC-099 (compound 1) stood out as a promising lead compound for further optimization. We coupled structure-based compound design with functional activity testing in neurons subjected to ER stress to develop a series of analogs with improved MAP4K inhibition and concomitant increases in potency and efficacy. Further structural modifications were performed to enhance the pharmacokinetic profiles of the compound 1 derivatives. Prostetin/12k emerged as an exceptionally potent, metabolically stable, and blood-brain barrier-penetrant compound that is well suited for future testing in animal models of neurodegeneration.

High-fat diets (HFDs) during pregnancy may damage the neural development and emotional behavior of rat offspring. Therefore, we investigated the neurobehavioral development of rat offspring who were fed a control diet (CD) or an HFD with lard (HFD-lard) or canola oil (HFD-canola oil), during pregnancy. Offspring's neurodevelopment (somatic growth, physical maturation, and ontogenesis reflex) was assessed while they were suckling. The rat's levels of depression, anxiety, and aggression were assessed through forced swimming, elevation plus a maze or open field test, and a foot-shock test on postnatal days 60, 80, and 110, respectively. Maternal HFDs with lard or canola oil promoted rats' offspring during suckling. They had reduced body weight and growth, physical maturation delay (auditory conduit and eyes opening to both groups HFDs-lard and canola oil; ear unfolding and incisor eruption only HFD-lard) and an ontogenesis reflex (palm grasp/vibrissa placing to both groups HFDs-lard and canola oil, and free-fall righting only in HFD-lard). Negative geotaxis resulted in the faster development of the HFD-lard offspring. Furthermore, in adulthood, the HDFs-offspring were more likely to be overweight, have shorter swimming times in the swim test, greater susceptibility to anxiety with an increased time spent in the closed arm in the elevated plus-maze while spending less time in the open arm, and having a decreased number of crossings and rearing in the open field. On the other hand, aggressive-like behavior was not affected. Therefore, these findings indicate that maternal HFDs enriched with lard or canola oil during pregnancy can impair the neurodevelopment of rat offspring and can perhaps be associated with possible changes to the emotional behavior of adult offspring.
