Gonadal development in scorpion mud‐turtles, Kinosternon scorpioides, in a controlled environment
The Anatomical Record, EarlyView.Stage 20 was identified as the critical point for gonadal differentiation in Kinosternon scorpioides, providing key insights into sex determination. These findings enhance conservation strategies by supporting reproductive management and population viability in both in situ and ex situ programs. Abstract Research on gonadal development including sexual

Effect of Ultrasound on Parthenogenic Activation of Mouse Oocyte [PDF]
Cell Journal, 2010 Objective: Artificial stimulation of mouse oocyte, in the absence of sperm contribution,can induce its parthenogenic activation of oocyte. Ultrasound is one of the newest methodsfor artificial activation of mammal oocytes, and its successful utilization ...

Cytostatic factor inactivation is induced by a calcium-dependent mechanism present until the second cell cycle in fertilized but not in parthenogenetically activated mouse eggs [PDF]
, 1995 Cytostatic factor (CSF) is an activity responsible for the metaphase II arrest in vertebrate oocytes. This activity maintains a high level of maturation promoting factor (MPF) in the oocyte and both activities are destroyed after fertilization or ...

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

Description of the sexual cycle related to the environment and set up of the artificial propagation in Pangasius bocourti (sauvage, 1880) and Pangasius hypophthalmus (Sauvage, 1878), reared in floating cages and in ponds in the Mekong Delta [PDF]
, 1998 First artificial propagation of Pangasius hypophthalmus was reported in Vietnam in 1980, but results did not allow extension for large scale production of fry. Otherwise, for P. bocourti, no reproduction was yet reported in 1994.
