Preantral follicle population and distribution in the horse ovary

open access: yesReproduction and Fertility, 2022
Characterization of the ovarian preantral follicle population is a necessary step to improve understanding of folliculogenesis and ovarian physiology. Therefore, in the present study, the preantral follicle population in the equine ovary in young and old

Follicular dynamics in zebu cattle [PDF]

open access: yesPesquisa Agropecuária Brasileira, 2000
The aim of this study was to investigate the follicular dynamics during estrous cycle in Gir breed (Bos indicus) cows. Follicular growth and atresia during estrous cycle were evaluated using a portable ultrasound device. Luteal activity was evaluated by serum progesterone levels.

miR-191 downregulation plays a role in thyroid follicular tumors through CDK6 targeting [PDF]

open access: yes, 2010
miR-191 expression is frequently altered in several neoplasias, being upregulated in some, such as pancreatic, colon, lung and prostate carinomas, and downregulated in others, such as severe medulloblastomas and melanomas.
