Role of oestradiol in growth of follicles and follicle deviation in heifers [PDF]

open access: yesReproduction, 2003
Follicle deviation is characterized by continued growth of the largest (developing dominant) follicle and reduced growth of the smaller (subordinate) follicles. The aim of the present study was to test the following hypotheses: (1). oestradiol contributes to the depression of circulating FSH encompassing follicle deviation and (2).

Leptin receptor in the chicken ovary: potential involvement in ovarian dysfunction of ad libitum-fed broiler breeder hens [PDF]

open access: yes, 2004
In hens, the ovarian follicles committed to ovulation are arranged in an ordered follicular hierarchy. In standard broiler breeders hens genetically selected for high growth rate the reproductive function is clearly dysfunctional.

Alopecia areata: a multifactorial autoimmune condition [PDF]

open access: yes, 2019
Alopecia areata is an autoimmune disease that results in non-scarring hair loss, and it is clinically characterised by small patches of baldness on the scalp and/or around the body. It can later progress to total loss of scalp hair (Alopecia totalis) and/

Hair Follicle Nevus [PDF]

open access: yesDermatology, 1992
We present a case of hair follicle nevus, a rare hamartoma composed of vellus hair follicles. Hair follicle nevus should be differentiated from accessory auricle, trichofolliculoma and hair nevus.

Estrogen Actions on Follicle Formation and Early Follicle Development1 [PDF]

open access: yesBiology of Reproduction, 2004
Estradiol-17beta (E(2)) affects late follicular development, whereas primordial follicle differentiation and early activation are believed to be independent of E(2). To test this hypothesis we compared numbers of primordial and primary follicles in wild-type and E(2)-deficient, aromatase knockout (ArKO) mice, and the immunohistochemical staining or ...

The spatiotemporal expression pattern of the bone morphogenetic protein family in rat ovary cell types during the estrous cycle. [PDF]

open access: yes, 2003
In the mammalian ovary, great interest in the expression and function of the bone morphogenetic protein (BMP) family has been recently generated from evidence of their critical role in determining folliculogenesis and female fertility.

Effects of short-term dietary supplementation on the number of ovarian follicles, quantity and quality of oocytes, and in vitro embryo production in Japanese Black cows

open access: yesThe Journal of Reproduction and Development, 2022
This study aimed to test the hypothesis that short-term supplementation with a high-energy diet promotes embryo production following ovum pick-up (OPU) in Japanese Black cows.

Comparison of PUFA profiles in the blood and in follicular fluid and its association with follicular dynamics after PGF2α induced luteolysis in dairy cows [PDF]

open access: yes, 2016
The objectives of the present study were to examine the fatty acid (FA) profiles in serum and in the follicular fluid (FF) and the association between polyunsaturated fatty acid level (PUFA) and follicular growth dynamics following induced luteolysis in ...
