Peripheral Microvascular and Cerebral White Matter Dysfunction in Schizophrenia: Implications of a Body-Brain Endothelial Pathophysiology.

Background And Hypothesis: Schizophrenia spectrum disorder (SSD) is a chronic neuropsychiatric illness accompanied by significant brain structural and functional abnormalities and higher rate of cardio- and cerebrovascular comorbidities. We hypothesized that genetic and environmental risk factors that led to SSD act throughout the body and demonstrated the association between lower integrity of peripheral vascular endothelium and white matter (WM) microstructure.

Study Design: Microvascular endothelial function was evaluated using brachial artery post-occlusive reactive hyperemia (PORH), in which endothelial responses are measured under reduced blood flow and after blood flow is restored.

Synchronized long-read genome, methylome, epigenome and transcriptome profiling resolve a Mendelian condition.

Resolving the molecular basis of a Mendelian condition remains challenging owing to the diverse mechanisms by which genetic variants cause disease. To address this, we developed a synchronized long-read genome, methylome, epigenome and transcriptome sequencing approach, which enables accurate single-nucleotide, insertion-deletion and structural variant calling and diploid de novo genome assembly. This permits the simultaneous elucidation of haplotype-resolved CpG methylation, chromatin accessibility and full-length transcript information in a single long-read sequencing run.

Residential exposure to spp is associated with exacerbations in COPD.

Background: Sensitisation to is linked to worse outcomes in patients with COPD; however, its prevalence and clinical implications in domestic (residential) settings remains unknown.

Methods: Individuals with COPD (n=43) recruited in Singapore had their residences prospectively sampled and assessed by shotgun metagenomic sequencing including indoor air, outdoor air and touch surfaces (a total of 126 specimens). The abundance of environmental and the occurrence of (Asp f) allergens in the environment were determined and immunological responses to allergens determined in association with clinical outcomes including exacerbation frequency.

Robust and Density Tunable Kevlar/Hexagonal Boron Nitride Microribbon Aerogels with Excellent Thermal, Mechanical, and Oil-Absorption Properties.

With rapid advancements in aerospace and supersonic aircraft technology, there is a growing demand for multifunctional thermal protective materials. Aerogels, known for their low density and high porosity, have garnered significant attention in this regard. However, developing a lightweight multifunctional aerogel that combines exceptional thermal and mechanical properties through a straightforward and time-efficient method remains a significant challenge.
