Background: The ε4 allele of the apolipoprotein E (APOE) gene is the strongest genetic determinant for Alzheimer's disease and cognitive function in nearly all human populations, yet inconsistent effects have been reported in South Asians. The population of India has admixed genetic ancestry with most people falling on a North/South cline and having varying proportions of Ancestral North Indian (ANI) and Ancestral South Indian (ASI) ancestries, and those in east of India fall off the cline due to ancestry from additional ancestral populations. This study examined the ε4 association with cognitive function across 18 states/union territories of India and investigated whether ancestral background modulates ε4 association with cognitive function in 2,590 participants from the Longitudinal Aging Study in India - Diagnostic Assessment of Dementia (LASI-DAD).

Two-dimensional (2D) superconductors, thanks to their rich physical properties, hold significant promise for both fundamental physics and potential applications in superconducting integrated circuits and quantum computation. Here, we report a gate-controlled superconducting switch in GaSe/NbSe van der Waals (vdW) heterostructure.

However, studies focusing on whether the orthopedic operation has an impact on the prognosis of geriatric hip fracture patients with CMVT are very limited. Therefore, the aim of this study was to explore whether geriatric hip fractures with CMVT affect the mortality of patients within one year postoperatively.

The extent of cryodamages varies significantly among different individual boars. In our study, 50 boars with either good sperm freezability (GSF) or poor sperm freezability (PSF) were selected from a population of 402 boars.

DNA methylation has been associated with both psychosocial stress and cardiometabolic disease; however, little is known about the mediating role of DNA methylation on the association between stress and cardiometabolic risk. Thus, using the high-dimensional mediation testing method, we conducted an epigenome-wide mediation analysis of the relationship between psychosocial stress and ten cardiometabolic risk factors in a multi-racial/ethnic population of older adults (n = 2668) from the Health and Retirement Study (mean age = 70.

Methods: We employed Summary-data based MR (SMR) analysis to assess the associations between gene molecular characteristics and GERD.
Although the prognosis of patients with multiple myeloma (MM) has been significantly improved by the introduction of proteasome inhibitors, immunomodulatory drugs and monoclonal antibodies, MM is still considered an incurable disease in the vast majority of the patients. In recent years, T-cell based immunotherapy represents a novel treatment strategy for relapsed/refractory (RR) MM. So far, chimeric antigen receptor (CAR) modified T-cells and bispecific T-cell engaging antibodies (bsAb) have shown promising anti-MM efficacy and manageable safety profile within clinical trials, and B-cell maturation antigen (BCMA) is the most commonly used immune target for T-cell based immunotherapies in MM.

Our study addresses the regioselectivity challenges commonly observed in asymmetric cyclopropenone transformations, substantiated by variations in substrate, Density Functional Theory calculations, and NMR analysis. This reaction is characterized by high efficiency, broad substrate scope, stability, latent biocompatibility, and mild reaction conditions.

Traditional histopathological examinations are insufficient to accurately predict hepatocellular carcinoma (HCC) survival; however, pathomics models can predict EZH2 expression and HCC prognosis. This study aimed to investigate the relationship between pathomics features and EZH2 expression for predicting overall survival of patients with HCC.

Although p53 regulates glycolytic metabolism, its role in cuproptosis remains unclear. Here, we report that the circular RNA, circFRMD4A, is crucial for p53-mediated metabolic reprogramming and cuproptosis.

While most existing TWAS approaches focus on marginal analyses through examining one gene at a time, recent developments in TWAS fine-mapping methods enable the joint modeling of multiple genes to refine the identification of potentially causal ones. However, these fine-mapping methods have primarily focused on modeling quantitative traits and examining local genomic regions, leading to potentially suboptimal performance.

Despite the impressive practical achievements, theoretical foundations underpinning the ability of neural networks to learn from functional data largely remain unexplored. In this paper, we investigate the approximation capacity of a functional neural network, called Fourier Functional Network, consisting of Fourier neural operators and deep convolutional neural networks with a great reduction in parameters.

Rac GTPase-activating protein 1 (RACGAP1), a member of the guanine triphosphatase-activating protein family, is highly overexpressed in multiple tumors and promotes tumor growth. However, the role of RACGAP1 in GHPA remains unelucidated.

A diradical-mediated hydrogen atom transfer (DHAT) of primary, secondary, and tertiary C(sp)-H bonds of o-alkyl arylsilylimines and C(sp)-H bonds of o-formyl arylsilylimines enabled a [4+2] annulation with olefins in excellent diastereoselectivity. This was accomplished upon irradiation at λ = 420 nm in the presence of thioxanthen-9-one (10 mol %) as the sensitizer via energy transfer.
