Sex-specific Associations of Gene Expression with Alzheimer's Disease Neuropathology and Ante-mortem Cognitive Performance.

The biological mechanisms underlying women's increased Alzheimer's disease (AD) prevalence remain undefined. Previous case/control studies have identified sex-biased molecular pathways, but sex-specific relationships between gene expression and AD endophenotypes, particularly sex chromosomes, are underexplored. With bulk transcriptomic data across 3 brain regions from 767 decedents, we investigated sex-specific associations between gene expression and post-mortem β-amyloid and tau as well as antemortem longitudinal cognition.

Drug repurposing screen targeting PARP identifies cytotoxic activity of efavirenz in high-grade serous ovarian cancer.

Drug repurposing has potential to improve outcomes for high-grade serous ovarian cancer (HGSOC). Repurposing drugs with PARP family binding activity may produce cytotoxic effects through the multiple mechanisms of PARP including DNA repair, cell-cycle regulation, and apoptosis. The aim of this study was to determine existing drugs that have PARP family binding activity and can be repurposed for treatment of HGSOC.

Metagenomic Profiling of Oral Microbiome Dynamics During Chemoradiotherapy in Head and Neck Squamous Cell Carcinoma Patients.

Background: We explored the interaction between the oral microbiome and the development of radiation-induced mucositis in patients with head and neck squamous cell cancer (HNSCC) undergoing chemoradiotherapy (CRT). We prospectively studied the oral microbiome and compared it to healthy controls. Additionally, we compared patients with low-grade (LGM) vs.

PTSD and CPTSD in the new ICD-11 - A latent profile analysis.

In the 11th version of the WHO´s International Classification of Diseases, complex post-traumatic stress disorder (CPTSD) is newly recognized as a variant of PTSD, characterized by additional and more severe symptoms and typically arising from prolonged or multiple traumatic experiences. Despite recent research supporting the differentiation between PTSD and CPTSD, studies also identify a third or even a fourth latent profile in trauma patients. This study employs latent profile analysis to identify the number of latent profiles within a clinical trauma population in Germany (N = 588) and aims to investigate their distinct symptomatology.

Linking Functional Traits To Trophic Roles In Scavenger Assemblages.

Scavenging is a widespread feeding strategy involving a diversity of taxa from different trophic levels, from apex predators to obligate scavengers. Scavenger species play a crucial role in ecosystem functioning by removing carcasses, recycling nutrients and preventing disease spread. Understanding the trophic roles of scavenger species can help identify specialized species with unique roles and species that may be more vulnerable to ecological changes.
