Comparative profiling of white matter development in the human and mouse brain reveals volumetric deficits and delayed myelination in Angelman syndrome.

Background: Angelman syndrome (AS), a severe neurodevelopmental disorder resulting from the loss of the maternal UBE3A gene, is marked by changes in the brain's white matter (WM). The extent of WM abnormalities seems to correlate with the severity of clinical symptoms, but these deficits are still poorly characterized or understood. This study provides the first large-scale measurement of WM volume reduction in children with AS.

CCR2 restricts IFN-γ production by hippocampal CD8 TRM cells that impair learning and memory during recovery from WNV encephalitis.

Central nervous system (CNS) resident memory CD8 T cells (T) that express IFN-γ contribute to neurodegenerative processes, including synapse loss, leading to memory impairment. Here, we show that CCR2 signaling in CD8 T that persist within the hippocampus after recovery from CNS infection with West Nile virus (WNV) significantly prevents the development of memory impairments. Using CCR2-deficient mice, we determined that CCR2 expression is not essential for CNS T cell recruitment or virologic control during acute WNV infection.

Molecular surveillance of Plasmodium falciparum histidine-rich protein 2/3 gene deletions in Mozambique, 2023.

Background: Rapid diagnostic tests (RDTs) based on the detection of Plasmodium falciparum histidine rich protein 2 (PfHRP2) are widely used for the diagnostic of P. falciparum in Africa. However, deletions of the pfhrp2 and pfhrp3 genes can lead to false negative test results and compromise appropriate case management.

Child mortality in Eastern Ethiopia: acceptability of Postmortem minimally invasive tissue sampling in a predominantly muslim community.

Background: It is crucial to consider cultural, religious, and socio-behavioural factors that may influence the acceptability of Minimally Invasive Tissues Sampling (MITS). MITS is being used to understand the causes of child death and conducted in nine countries within Africa and South Asia with the highest child mortality. Progress has been made in the development of laboratory infrastructures and training for physicians to do MITS, but many communities are concerned about the religious acceptability of taking samples from deceased children.

U-shaped association of uric acid to HDL cholesterol ratio (UHR) with ALL-cause and cardiovascular mortality in diabetic patients: NHANES 1999-2018.

Objective: To investigate the relationship between the uric acid to high-density lipoprotein cholesterol ratio (UHR) and ALL-cause and cardiovascular mortality among diabetic patients.

Methods: This study utilized health data from diabetic patients included in the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018. The Kaplan-Meier curves was employed to preliminarily explore the association between UHR, its components, and all-cause and cardiovascular mortality in diabetic patients, as well as to analyze UHR levels and mortality across different genders.

Measuring the biomechanical properties of cell-derived fibronectin fibrils.

Embryonic development, wound healing, and organogenesis all require assembly of the extracellular matrix protein fibronectin (FN) into insoluble, viscoelastic fibrils. FN fibrils mediate cell migration, force generation, angiogenic sprouting, and collagen deposition. While the critical role of FN fibrils has long been appreciated, we still have an extremely poor understanding of their mechanical properties and how these mechanical properties facilitate cellular responses.

Neighborhood Income Disparities in Unplanned Hospital Admission and In-Hospital Outcomes Among Children with Congenital Heart Disease.

Unplanned admissions are associated with worse clinical outcomes and increased hospital resource utilization. We hypothesized that children with congenital heart disease (CHD) from lower-income neighborhoods have higher rates of unplanned hospital admissions and greater resource utilization. Utilizing the Kids' Inpatient Database (2016 and 2019), we included children under 21 years of age with CHD, excluding newborn hospitalizations.

Association of α-klotho concentrations with cardiovascular and all-cause mortality in American adults with depression: a national prospective cohort study.

This study examines α-klotho levels in depressed American adults and their association with cardiovascular disease and all-cause mortality, utilizing data from the National Health and Nutrition Examination Survey (2007-2016) and mortality details from the National Death Index up to December 31, 2019. Including 3329 participants with depression, findings revealed 485 all-cause and 113 cardiovascular deaths. To investigate the nonlinear association between α-klotho and mortality, the Cox proportional hazards regression model, restricted cubic splines, and two-piecewise Cox proportional hazards model were developed.

Assessing initial/early aversion-resistant drinking across male and female alcohol-preferring and non-preferring rats.

Background: One trait of alcohol use disorder (AUD) is continuing to drink despite negative consequences. The current study investigated initial/early aversion-resistant drinking (ARD) across selectively bred alcohol-preferring lines to assess aversion resistance with minimal ethanol history and subsequent ethanol-seeking and drinking profiles. Additionally, ARD was assessed in alcohol-preferring and non-preferring rats using a sucrose reinforcer to determine if ARD may be a genetic risk factor for AUD.

Influence of Vessel Geometry, Flow Conditions, and Thrombin Concentration on Fibrin Accumulation and Cerebral Aneurysm Occlusion After Flow Diversion.

As the number of cerebral aneurysms treated with flow diverters continues to increase, it is important to understand what factors influence not only thrombus formation within the aneurysm cavity but also fibrin accumulation across the device and its associated disruption and blockage of the inflow stream. Both processes contribute to the eventual occlusion of the aneurysm or its continued patency and incomplete occlusion which may require future re-treatment. To investigate fibrin accumulation on flow diverters placed across the neck of cerebral aneurysms, a previously developed computational model that couples flow and fibrin dynamics is used in combination with experimental in vitro models of cerebral aneurysms treated with flow diverters.

Neural dynamics of social verb processing: An MEG study.

Human vocabularies include specific words to communicate interpersonal behaviors, a core linguistic function mainly afforded by social verbs (SVs). This skill has been proposed to engage dedicated systems subserving social knowledge. Yet, neurocognitive evidence is scarce, and no study has examined spectro-temporal and spatial signatures of SV access.

Tunable Terpolymer Series for the Systematic Investigation of Membrane Proteins.

Membrane proteins (MPs) are critical to cellular processes and serve as essential therapeutic targets. However, their isolation and characterization are often impeded by traditional detergent-based methods, which can compromise their native states, and retention of their native lipid environment. Amphiphilic polymers have emerged as effective alternatives, enabling the formation of nanoscale discs that preserve MPs' structural and functional integrity.

Competition between Bipolar Conduction Modes in Extrinsically -Doped MoS: Interaction with Gate Dielectric Matters.

With reduced dimensionality and a high surface area-to-volume ratio, two-dimensional (2D) semiconductors exhibit intriguing electronic properties that are exceptionally sensitive to surrounding environments, including directly interfacing gate dielectrics. These influences are tightly correlated to their inherent behavior, making it critical to examine when extrinsic charge carriers are intentionally introduced to the channel for complementary functionality. This study explores the physical origin of the competitive transition between intrinsic and extrinsic charge carrier conduction in extrinsically -doped MoS, highlighting the central role of interactions of the channel with amorphous gate dielectrics.

Methods: Seven databases were searched for studies evaluating weight reduction of Food and Drug Administration (FDA)-approved AOMs. Studies had to include adults ages ≥65 years with obesity (BMI ≥ 30 kg/m or ≥27 kg/m with one weight-related condition), with independent analysis of weight reduction for adults ages ≥65 years.

The Topology of Poly(2-methyl-2-oxazine) Shells on Nanoparticles Determines Their Interaction with Serum and Uptake by Immune Cells.

Cyclic poly(2-methyl-2-oxazine) (-PMOZI) brush shells on Au nanoparticles (NPs) exhibit enhanced stealth properties toward serum and different cell lines compared to their linear PMOZI (-PMOZI) counterparts. While selectively recruiting immunoglobulins, -PMOZI shells reduce overall human serum (HS) protein binding and alter the processing of complement factor 3 (C3) compared to chemically identical linear shells. Polymer cyclization significantly decreases NP uptake by nonphagocytic cells and macrophages in both complement-deficient fetal bovine serum (FBS) and complement-expressing HS, indicating ineffective functional opsonization.
