Prevalence and Risk Factors of Dementia Among Older People of Gelao Ethnicity in China: A National Cross‐Sectional Study

CNS Neuroscience &Therapeutics, Volume 32, Issue 5, May 2026.
This study reveals a 24.74% prevalence of dementia among elderly Gelao people in China, with women's rates more than double those of men and substantially exceeding the national average. We identify distinct sociocultural protective factors—including community engagement and traditional diets—alongside risk factors.

Parvimonas micra promotes carcinogenesis of colorectal cancer through phenyllactic acid‐induced DNA damage

Clinical and Translational Medicine, Volume 16, Issue 5, May 2026.
Multiomics analysis of the faecal samples from CRC patients found that upregulation of P. micra and PLA was associated with the CRC development. PLA from P. micra via pdhD genes could induce DNA damage via AHR signalling pathway to mediate carcinogenesis.

Host Factor Induced Bacterial Extracellular Vesicles Promote Horizontal Gene Transfer in Vibrio cholerae

Journal of Extracellular Vesicles, Volume 15, Issue 5, May 2026.
Antimicrobial stressors, that is, bile or mitomycin C, induce enlarged, nucleic acid‐rich bacterial extracellular vesicles in Vibrio cholerae that facilitate horizontal gene transfer in vitro and during intestinal colonisation. The findings provide a detailed comparison of control versus stress‐induced vesicles, identify bile as a host factor shaping ...

Xanthatin‐13‐(Pyrrolidine‐2‐Carboxylic Acid), a Sesquiterpene Lactone Isolated From Burdock Leaf, Attenuated Aβ25‐35 Toxicity and Memory Deficits in a Pharmacological Mouse Model of Alzheimer's Disease

Phytotherapy Research, Volume 40, Issue 5, Page 2824-2843, May 2026.
ABSTRACT Alzheimer's disease (AD) is a severe form of dementia, which occurrence increases with age and lifestyle conditions. It is characterized by amyloid protein accumulation forming senile plaques, hyperphosphorylated tau protein forming neurofibrillary tangles, neuroinflammation, and oxidative stress, leading to synapse loss and cell death ...

Anaerobe‐Driven Inflammation and Epithelial Barrier Disruption in Genital HIV Acquisition

American Journal of Reproductive Immunology, Volume 95, Issue 5, May 2026.
ABSTRACT Background Genital microbiome dysbiosis is an important risk factor for the sexual acquisition of human immunodeficiency virus (HIV) in both the male and female genital tracts. The vaginal, penile and urethral mucosae are distinct microenvironments with characteristic microbiome compositions.
