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 ...

A validated model of serum Anti-Müllerian hormone from conception to menopause [PDF]

, 2011
<p><b>Background:</b> Anti-Mullerian hormone (AMH) is a product of growing ovarian follicles. The concentration of AMH in blood may also reflect the non-growing follicle (NGF) population, i.e.

Expression of Relaxin Family Peptide Receptors 1 and 3 in the Ovarian Follicle of Japanese Quail

The Journal of Poultry Science
In our previous studies, we demonstrated that the primary source of relaxin 3 (RLN3) in Japanese quail is ovarian granulosa cells. Although several relaxin family peptide (RXFP) receptors have been sequenced, the intricacies of these receptors in avian ...

Induction of accessory corpus luteum by gonadorelin in relation to the time of treatment and the follicle size in inseminated cows

Czech Journal of Animal Science, 2017
This study evaluated the occurrence of two corpora lutea (CL) and the pregnancy rate in cows treated with gonadorelin on days 5, 6 or 7 after insemination in relation to the day of treatment and the size of the largest follicle on the ovaries at the time

Activin B is produced early in antral follicular development and suppresses thecal androgen production [PDF]

, 2012
Little is known about the role of activin B during folliculogenesis. This study investigated the expression levels of activin/inhibin subunits (βA, βB, and α), steroid enzyme, and gonadotrophin receptors in theca (TC) and granulosa cells (GC) by QPCR and

Hair Follicle Nevus [PDF]

Dermatology, 2009
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.

The relation between variation in size of the primordial follicle pool and age at natural menopause [PDF]

, 2015
Context: Tumors producing insulin-like growth factor 2 (IGF-2oma) are a major cause of spontaneous hypoglycemia. The treatment mainstay is surgical resection.

Human oocyte capacitation culture: Essential step toward hormone‐free assisted reproductive technology

Reproductive Medicine and Biology
Background In vitro oocyte maturation (IVM) is not a novel concept; however, its wide‐scale practice has been limited because of the lower clinical outcomes compared to conventional assisted reproductive technologies.
