Histological Characterization and Comparative Transcriptomic Analysis of Gonads During Early Sex Differentiation in the Northern Snakehead (Channa argus)

open access: yesAnimal Research and One Health, EarlyView.
This study delineates the early sex differentiation timeline in the northern snakehead (Channa argus). These findings provide a foundation for future sex‐control breeding in this economically important species. ABSTRACT The northern snakehead (Channa argus) is an economically important aquaculture species in China.

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

open access: yesAnimal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable

The Role of Steroid Hormones on the Modulation of Neuroinflammation by Dietary Interventions

open access: yesFrontiers in Endocrinology, 2016
Steroid hormones, such as sex hormones and glucocorticoids, have been demonstrated to play a role in different cellular processes in the central nervous system, ranging from neurodevelopment to neurodegeneration.

Psychomotor reminiscence as a function of gonadal steroid hormone variation [PDF]

open access: yesBulletin of the Psychonomic Society, 1979
Psychomotor reminiscence was studied in relation to endogenous variations in estrogenic hormone levels. Forty-three young adult females monitored their menstrual cycles for two replications, then reported for testing on Day 2, 8, or 14 of their cycles.

Investigation of \u3cem\u3ede novo\u3c/em\u3e cholesterol synthetic capacity in the gonads of goldfish (\u3cem\u3eCarassius auratus\u3c/em\u3e) exposed to the phytosterol beta-sitosterol [PDF]

open access: yes, 2006
Total and intra-mitochondrial gonadal cholesterol concentrations are decreased in fish exposed to the phytoestrogen beta-sitosterol (beta-sit). The present study examined the potential for beta-sit to disrupt de novo cholesterol synthesis in the gonads ...
