A central characteristic of Alzheimer's disease (AD) and other tauopathies is the accumulation of aggregated and misfolded Tau deposits in the brain. Tau-targeting therapies for AD have been unsuccessful in patients to date. Here we show that human polymerase δ-interacting protein 2 (PolDIP2) interacts with Tau. With a set of complementary methods, including thioflavin-T-based aggregation kinetic assays, Tau oligomer-specific dot-blot analysis, and single oligomer/fibril analysis by atomic force microscopy, we demonstrate that PolDIP2 inhibits Tau aggregation and amyloid fibril growth in vitro. The identification of PolDIP2 as a potential regulator of cellular Tau aggregation should be considered for future Tau-targeting therapeutics.

Objective: Early and accurate diagnosis of prostate cancer (PC) is crucial for effective treatment. Diagnosing clinically insignificant cancers can lead to overdiagnosis and overtreatment, highlighting the importance of accurately selecting patients for further evaluation based on improved risk prediction tools. Novel biomarkers offer promise for enhancing this diagnostic process.

Cutaneous photoaging, induced by chronic exposure to ultraviolet (UV) radiation, typically manifests as alterations in both the physical appearance and functional properties of the skin and may predispose individuals to cancer development. Recent studies have demonstrated the reparative potential of exosomes derived from mesenchymal stem cells in addressing skin damage, while specific reports highlight their efficacy in ameliorating skin photoaging. However, the precise role of exosomes derived from human hair follicle mesenchymal stem cells (HFMSC-Exos) in the context of cutaneous photoaging remains largely unexplored.

BACKGROUND The bacterial organism Capnocytophaga canimorsus is an oral commensal of cats and dogs and can cause life-threatening infections like mycotic aneurysm, meningitis, and sepsis. Mycotic aneurysms occur when microbial infections cause arterial wall degeneration. Difficulty in diagnosing Capnocytophaga canimorsus infection can occur due to the bacteria's fastidious nature and laboratory testing limitations, contributing to the infection's high morbidity and mortality.

Introduction: is a major health problem, with the high prevalence of and the increasing antibiotic resistance rate in China. Antibiotic resistance is the main reason for the failure of eradication. This study aims to evaluate the efficacy and safety of susceptibility-guided quadruple therapy with antibiotic resistance using the string test coupled with quantitative PCR (qPCR) for eradication.

Simulated cases of diagnostic uncertainty regarding infection resolution led clinicians to choose options such as procalcitonin (PCT) and/or PCR-POCTs +/- de-escalation to aid stop decisions. We hypothesised that a direct infection indicator, PCR-POCT, would influence stop judgements more than indirect PCT.
