Cost-effective solutions for high-throughput enzymatic DNA methylation sequencing.

Characterizing DNA methylation patterns is important for addressing key questions in evolutionary biology, geroscience, and medical genomics. While costs are decreasing, whole-genome DNA methylation profiling remains prohibitively expensive for most population-scale studies, creating a need for cost-effective, reduced representation approaches (i.e.

Social network shrinking is explained by active and passive effects but not increasing selectivity with age in wild macaques.

Evidence of social disengagement, network narrowing and social selectivity with advancing age in several non-human animals challenges our understanding of the causes of social ageing. Natural animal populations are needed to test whether social ageing and selectivity occur under natural predation and extrinsic mortality pressures, and longitudinal studies are particularly valuable to disentangle the contribution of within-individual ageing from the demographic processes that shape social ageing at the population level. Data on wild Assamese macaques () were collected between 2013 and 2020 at the Phu Khieo Wildlife Sanctuary, Thailand.

Aging gut microbiota of wild macaques are equally diverse, less stable, but progressively personalized.

Background: Pronounced heterogeneity of age trajectories has been identified as a hallmark of the gut microbiota in humans and has been explained by marked changes in lifestyle and health condition. Comparatively, age-related personalization of microbiota is understudied in natural systems limiting our comprehension of patterns observed in humans from ecological and evolutionary perspectives.

Results: Here, we tested age-related changes in the diversity, stability, and composition of the gut bacterial community using 16S rRNA gene sequencing with dense repeated sampling over three seasons in a cross-sectional age sample of adult female Assamese macaques (Macaca assamensis) living in their natural forest habitat.

Performers' Perceptions of Vocal Function During Oral Steroid Treatment of Vocal Fold Edema.

Objectives: Acute vocal fold edema (VFE) is often a consequence of illness, allergy, or voice overuse, causing dysphonia. Although VFE typically resolves with voice rest and treatment of predisposing causes, oral glucocorticoids are often considered for performers with imminent performance demands. There are limited data about performers' perceptions of vocal change during treatment and how this relates to their ability to perform.
