Soil carbon and nitrogen cycling at the atmosphere–soil interface: Quantifying the responses of biocrust–soil interactions to global change

Global Change Biology, Volume 30, Issue 10, October 2024.
Despite the critical role of biological soil crusts (biocrusts) in dryland C and N cycles, little is known about how biocrust‐derived C and N move into the soil. This study reveals how biocrusts facilitate the downward movement of C and N and drive the formation of mineral‐associated organic matter in subcrust soils.

C‐reactive protein (CRP) in high altitude Bolivian peri‐urban adolescents varies by adiposity, current illness, height, socioeconomic status, sex, and menarcheal status: The potential benefits and costs of adipose reserves in arduous environments

American Journal of Human Biology, Volume 36, Issue 9, September 2024.
Abstract Objectives In non‐industrialized and low‐income populations, adipose stores can serve as a valuable buffer against harsh conditions such as seasonal food scarcity. However, these reserves may incur costs due to adipocytes' production of pro‐inflammatory cytokines; inflammation is associated with increased risk for cardiometabolic diseases ...

Hydroxycitrate delays early mortality in mice and promotes muscle regeneration while inducing a rich hepatic energetic status

Aging Cell, Volume 23, Issue 9, September 2024.
ATP citrate lyase (ACLY) inhibitors have been proposed as calorie restriction mimetics. We performed a longevity assay in mice using the ACLY inhibitor hydroxycitrate. We observed that hydroxycitrate delays early mortality, having pleiotropic effects in muscle and liver physiology.

A placebo‐controlled, double‐blind study evaluating the effect of orally administered polyunsaturated fatty acids on the oclacitinib dose for atopic dogs

Veterinary Dermatology, Volume 35, Issue 4, Page 408-417, August 2024.
Background – Supplementation of polyunsaturated fatty acids (PUFA) enables dose reduction of prednisolone and ciclosporin in canine atopic dermatitis (cAD). Objective – To determine if oral administration of PUFA can reduce the dose of oclacitinib for cAD. Conclusion – Oral supplementation of PUFA allowed dose reduction of oclacitinib and improved pVAS,
