Hepatotoxicity of Nonesterified Fatty Acids to Dairy Cows: Pathophysiological Mechanisms and Prospective Solutions

open access: yesAnimal Research and One Health, EarlyView.
Unregulated inflammation increases non‐esterified fatty acids (NEFAs), and triggers multi‐pathway hepatocyte damage including oxidative stress, mitochondrial dysfunction, and metabolic disorders in dairy cows. ABSTRACT Circulating concentrations of nonesterified fatty acids (NEFAs) are elevated due to lipid mobilization from adipose tissue in ...

Effect of microfluidic and density gradient techniques to select frozen-thawed epididymal sperm from Bighorn rams

open access: yesTheriogenology Wild
Gamete preservation of wild species is a priority in conservation programs. However, field techniques to recover sperm from deceased animals may impair its final quality.The cryopreservation process also has its challenges, and the minimal required ...

Use of Clotrimazole in Finfish Aquaculture: Mechanistic Insights, Limitations, and Future Directions for Antifungal Therapy

open access: yesAnimal Research and One Health, EarlyView.
This review critically evaluates clotrimazole as a potential antifungal for finfish aquaculture, highlighting strong mechanistic and in vitro efficacy against aquatic mycoses alongside major gaps in in vivo evidence, toxicokinetics, residue safety, and environmental risk, outlining priorities for responsible therapeutic development and regulatory ...

Modern competency‐based teaching of human sexual development

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Embryology is an integral part of anatomy and a key subject in basic medical education. The development of the sexual tract, which is closely associated with the formation of the urinary tract and the organs of continence, is particularly complex and relevant for many medical disciplines.

Oocyte–cumulus cell interaction: a key factor in early embryo development

open access: yesBiological Reviews, EarlyView.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.

The costs of extra‐pair behaviours in birds

open access: yesBiological Reviews, EarlyView.
ABSTRACT Extra‐pair behaviours – reproductive behaviours, including those related to copulation and paternity of offspring, amongst animals outside of a social pair bond – have long intrigued behavioural ecologists, particularly from the female animal's perspective.

Sperm Separation and Selection Techniques to Mitigate Sperm DNA Damage

open access: yesLife
Semen preparation and sperm selection techniques exploit the morphological and physiological characteristics of sperm function, including motility, morphology, density, and maturity, as reflected by their cell-surface charge and the expression of hyaluronan receptors. The various methods employed have a common purpose of mimicing sperm selection within

Bifunctional Photocatalysts: Exploiting Proximity for Enhanced Reaction Performance

open access: yesChemistry – A European Journal, EarlyView.
This review covers the application of the bifunctional approach to photocatalysis as a means to attain (enhanced) enantioselectivity, and, more in general, as a strategy to enhance the catalytic performance through an effective use of short‐lived reaction intermediates.
