Effects of Prepartum Supplementation and Yeast Fermentation Products on the Progesterone‐Modulated Transfer of Passive Immunity in Bos indicus Cows

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Inadequate colostrum intake increases risks of calf morbidity and mortality. This study investigated the effects of prepartum and early postpartum supplementation and yeast fermentation products on late‐pregnant Bos indicus cows, and the role of progesterone in mediating passive immunity transfer.

Relative Exchangeable Copper Confirms Wilson Disease and Supports Reclassification of the ATP7B p.Met665Ile Variant With Conflicting Pathogenicity Evidence

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 7, Page 1691-1695, July 2026.
ABSTRACT Wilson disease (WD) is an autosomal recessive disorder of copper metabolism caused by ATP7B mutations. Diagnosis is usually straightforward in symptomatic patients, but can be challenging in children and adolescents with mild liver disease, borderline urinary copper excretion, or inconclusive genetic findings.

Method Comparison of Dried Blood Spot and Plasma Apolipoprotein B Measurement on a Semi‐Automated Analyser: Toward Accessible Lipid Profiling in Resource‐Limited Settings

open access: yesAnalytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT Apolipoprotein B (ApoB) is a key marker of atherogenic lipoprotein burden, but conventional plasma‐based testing requires venous sampling and centralized laboratory infrastructure. Dried blood spot (DBS) sampling offers a minimally invasive alternative suitable for decentralized settings.

Risk Factors for and Prevalence of Failure of Passive Transfer of Immunity in Calves on Dairy Farms in Türkiye

open access: yesVeterinary Medicine and Science, Volume 12, Issue 3, May 2026.
The prevalence of FPTI in this study was similar to reports internationally. This research shows that there were both modifiable and non‐modifiable significant risk factors for FPTI in Türkiye dairy herds, specifically colostrum feeding method and season of birth and herd size, dam parity and calf breed.

A Monoclonal Antibody ELISA–Based Assay for Measuring the Potency of Candidate H5 Clade 2.3.4.4b Pandemic Influenza Vaccines

open access: yesInfluenza and Other Respiratory Viruses, Volume 20, Issue 3, March 2026.
ABSTRACT Background The single radial immunodiffusion (SRID) assay is used to determine the potency of inactivated influenza vaccines. Nevertheless, development of alternative influenza vaccine potency assays with greater sensitivity and less reliance on large quantities of reference reagents is needed.
