Synchronization of ovulation in crossbred dairy heifers using gonadotrophin-releasing hormone agonist, prostaglandin F2a and human chorionic gonadotrophin or estradiol benzoate [PDF]
Brazilian Journal of Medical and Biological Research, 2000 Girolando (Gir x Holstein) is a very common dairy breed in Brazil because it combines the rusticity of Gir (Bos indicus) with the high milk yield of Holstein (Bos taurus).

Influence of human chorionic gonadotrophin during ovarian stimulation: an overview
Reproductive Biology and Endocrinology, 2020 It is widely known that luteinising hormone (LH) and human chorionic gonadotrophin (hCG) are integral in the female reproductive lifecycle. Due to the common binding site and similarity in molecular structure, they were previously thought to have ...

Hair Follicle Pigmentation [PDF]
Journal of Investigative Dermatology, 2005 Hair shaft melanin components (eu- or/and pheomelanin) are a long-lived record of precise interactions in the hair follicle pigmentary unit, e.g., between follicular melanocytes, keratinocytes, and dermal papilla fibroblasts. Follicular melanogenesis (FM) involves sequentially the melanogenic activity of follicular melanocytes, the transfer of melanin ...

The Inflammasome Contributes to Depletion of the Ovarian Reserve During Aging in Mice
Frontiers in Cell and Developmental Biology, 2021 Ovarian aging is a natural process characterized by follicular depletion and a reduction in oocyte quality, resulting in loss of ovarian function, cycle irregularity and eventually infertility and menopause.

Apoptosis in the Hair Follicle [PDF]
Journal of Investigative Dermatology, 2006 Apoptosis plays an important role in many physiological processes, ranging from morphogenetic events to adult tissue homeostasis, and defects in its regulation contribute to many disorders. Here we review molecular mechanisms of apoptosis in the hair follicle (HF), whose cyclical growth pattern is repeatedly interrupted by apoptosis-driven involution ...

Age as A Predictor of Embryo Quality Regardless of The Quantitative Ovarian Response [PDF]
International Journal of Fertility and Sterility, 2017 Background One determining factor of a successful in vitro fertilization (IVF) cycle is embryo quality. The aim of the present study was to evaluate associations of embryo quality and reserve markers like age, FSH and AMH.

Control of antral follicle development and selection in sheep and cattle.
Journal of reproduction and fertility. Supplement, 2019 The development of antral follicles in sheep and cattle is dependent on FSH, but large antral follicles can shift their gonadotrophic dependence from FSH to LH. The mechanisms that result in the selection of at least one ovulatory follicle from identical
