Impact of the phenotypic and genetic merit of growth, reproduction, and carcass traits on sexual precocity in Nelore heifers using multivariate analysis techniques [PDF]

The aim was to verify, using multivariate techniques, which growth and carcass traits, and their variations throughout the reproductive season, are related to the sexual precocity of Nellore heifers.

Sperm Telomere Interactions Are Impaired in Testicular Cancer Before and After Adjuvant Therapy

Andrology, EarlyView.
ABSTRACT Background No study has yet explored telomere length or interaction in sperm nuclei of testicular cancer (TC) patients exposed to chemotherapy or radiotherapy. However, sperm telomere dynamics have emerged as a potential marker in male infertility.

Human ovarian reserve from conception to the menopause [PDF]

, 2009
Current understanding is that the human ovary contains a fixed number of several million non-growing follicles (NGF), established by five months of gestational age, that declines with increasing age to the menopause when approximately 1,000 NGF remain at

The demography of an Osprey population under natural recolonisation and translocation processes

Ibis, EarlyView.
In a context of global biodiversity loss, studying the processes underlying the recolonisation—whether natural or assisted—of expanding species provides essential insights for the development of effective conservation strategies. Since the 1980s, the Osprey Pandion haliaetus has naturally recolonized mainland central and eastern France, increasing from

Identification of candidate genes and ceRNA networks of HPG axis in regulating sexual precocity of roosters by whole transcriptomic sequencing

BMC Genomics
Background Precocious puberty in chickens is an important biological trait regulated by the hypothalamic-pituitary–gonadal (HPG) axis. The comb height of roosters is an indicator of precocious puberty in breeding.
