Immunosenescence Profile Is Associated With Increased Susceptibility to Severe COVID‐19

Aging Cell, Volume 24, Issue 7, July 2025.
(A) A previous immunosenescence profile in individuals infected with SARS‐CoV2 creates a permissive environment for progression to severe COVID‐19: higher inflammaging, accumulation of exhausted/senescent T cells, an oligoclonal B‐cell repertoire, and accelerated epigenetic age.

Placental biomarker and fetoplacental Doppler abnormalities are strongly associated with placental pathology in pregnancies with small‐for‐gestational‐age fetus: prospective study

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 6, Page 749-760, June 2025.
ABSTRACT Objective Placental dysfunction can result in small‐for‐gestational age (SGA) or fetal growth restriction (FGR). The aim of this prospective cohort study was to assess the association of the cerebroplacental ratio (CPR) and other more conventional fetoplacental Doppler indices, circulating placental growth factor (PlGF) levels and soluble fms ...

Claw growth rates in a subset of adult, indoor, domestic cats (Felis catus)

Veterinary Dermatology, Volume 36, Issue 3, Page 362-367, June 2025.
Background – Keratinised tissues, such as nails and claws, accumulate hormones over time; the claws' hormone concentrations are being explored as potential biomarkers. Timelines for hormone deposition can be established if claw growth rates are known. Hormone concentration within cat claws has been recently evaluated, yet the growth rates of cat claws ...
