Microbial Contributions to Primate Reproduction

Evolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 1, March 2026.
ABSTRACT Reproduction is a complex process, and microbes play a far greater role than previously imagined. This review explores the ways that microbiomes influence the rich tapestry of reproductive processes and outcomes within the primate lineage, including pre‐copulatory and post‐copulatory mechanisms.

Identification of Citri Reticulatae Pericarpium (Chenpi) From Different Cultivars via LC–MS/MS and UPLC Coupled With Multivariate Chemometrics Analysis

Food Science &Nutrition, Volume 14, Issue 3, March 2026.
A UPLC‐based quantitative analysis combined with multivariate chemometric methods differentiated seven Citri Reticulatae Pericarpium cultivars based on significant variations in nine flavonoids. Chemometric analysis effectively separated the seven cultivars, and hesperetin was identified as a unique marker for C. reticulata “Chachi”.

Enhancing polyphenol synthesis and antioxidant activity in Camellia sinensis using shikimic and salicylic acids

JSFA reports, Volume 6, Issue 3, Page 73-87, March 2026.
Abstract Background Camellia sinensis, widely consumed as tea, is the second most popular beverage globally and is valued for its health benefits. However, environmental stressors pose a significant challenge to the tea industry. This study investigates the potential of shikimic acid (ShA) and its derivative, salicylic acid (SA), as inducers to enhance
