Effect of Estradiol and Nonylphenol on mRNA Levels of VitellogeninII in the Liver of Chicken Embryos
The Journal of Poultry Science, 2001 Nonylphenol is one of the endocrine disrupting agents with estrogenic activity in some vertebrates. The present study was conducted to assess estrogenic activity of p-nonylphenol (NP) in chicken embryos by determining mRNA levels of liver vitellogenin II

The 9+ month marathon: How pregnancy may have shaped human endurance capacities
The Anatomical Record, EarlyView.Abstract Anthropology has long considered the evolution of our uniquely human endurance capacities to be the result of selection upon anatomical and physiological features imposed by the demands of thermoregulation and resource acquisition, particularly during the demands of persistence hunting. Research has focused on the anatomical changes present in

A pilot study of the visible effects of estradiol on human intestinal cells in tissue culture [PDF]
, 1971 The purpose of this tissue culture study was to determine whether physiological levels of the steroid 17-B - estradiol would stimulate visible changes in morphology or growth of adult human fibroblastic cells derived from the large intestine, a non ...

Postnatal craniomandibular growth in Harbor seals (Phoca vitulina vitulina)
The Anatomical Record, EarlyView.Postnatal ontogeny in Harbor seals (Phoca vitulina vitulina). Cranium and mandible grow rapidly until 5 years of age, followed by a deceleration and finally a stagnation. Abstract As secondarily aquatic carnivores, seals display several phenotypic differences compared to their terrestrial relatives.

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
