Cyclic Treatment With WIN 18,446, a Potential Male Contraceptive, is as Effective as Continuous Treatment for Suppression of Spermatogenesis in Mice

Andrology, Volume 14, Issue 6, Page 1472-1478, September 2026.
ABSTRACT Background Retinoic acid plays a critical role in spermatogenesis during both spermatogonial differentiation and spermiation. Mice lacking enzymes that synthesize retinoic acid, Aldh1a1/1a2, in the testes are infertile. WIN 18,446 reversibly inhibits spermatogenesis by inhibiting ALDH1A1/1A2 and is a promising approach to male contraception ...

Free Fatty Acids Carried by Lipoproteins: Revisiting the Overlooked Cargo

Acta Physiologica, Volume 242, Issue 9, September 2026.
ABSTRACT Free fatty acids (FFAs) are hydrophobic and therefore cannot enter the bloodstream at appreciable levels unless they are solubilized by FFA carriers. Albumin has been appreciated for years as the major FFA carrier, but it is not the only carrier.

Pharmacological activation of NO‐cGMP signalling attenuates metabolic dysfunction‐associated steatohepatitis

British Journal of Pharmacology, Volume 183, Issue 18, Page 5476-5495, September 2026.
Background and Purpose Metabolic dysfunction‐associated steatohepatitis (MASH) is linked to activation of hepatic stellate cells (HSCs) to α‐smooth muscle actin–positive myofibroblasts that produce collagen and proinflammatory cytokines. Quiescent HSCs express the NO‐cGMP signalling axis.

Physicochemical Quality and Chemical Safety of Commercial Wet Cat Food: Composition, Oxidation, Biogenic Amines, and Trace Elements

Journal of Animal Physiology and Animal Nutrition, Volume 110, Issue 5, Page 663-673, September 2026.
ABSTRACT This study investigated the physicochemical characteristics and chemical safety of commercial wet cat foods marketed in Brazil. Twenty products labeled as beef, chicken and fish flavors were analyzed for proximate composition, pH, lipid and protein oxidation, biogenic amines, and essential and potentially toxic trace elements.

Effect of Dietary Vitamin A, Breed, and Kidney Function on the Onset of Urinary Vitamin A Excretion and the Vitamin A Transport Complex in Growing Dogs

Journal of Animal Physiology and Animal Nutrition, Volume 110, Issue 5, Page 813-819, September 2026.
ABSTRACT Vitamin A (retinol and retinyl esters) is present in substantial amounts in the urine of healthy adult dogs, but the mechanisms affecting its excretion are poorly understood. To assess whether the onset of urinary vitamin A excretion is dependent on dietary vitamin A intake, breed, and/or parameters of kidney function, 48 puppies from two ...

Molecular Mechanism of Absorption, Transport and Metabolic Transformation of Astaxanthin in Aquatic Animals

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
This manuscript systematically elucidates the molecular mechanisms underlying absorption, transport, and metabolism of Astaxanthin in aquatic animals, through the analysis of biological functions, transport proteins, and enzyme metabolism system. Furthermore, it outlines future molecular research strategies for Astaxanthin, providing a theoretical ...
