Journal ArticleDOI
Secondary structural studies of bovine caseins: temperature dependence of β-casein structure as analyzed by circular dichroism and FTIR spectroscopy and correlation with micellization
TL;DR: In this article, the secondary structure of bovine β-casein was re-examined using Fourier transform infrared and circular dichroism spectroscopies to test these predictions.
Journal ArticleDOI
Hepatic and extrahepatic expression of vitellogenin genes in the zebrafish, Danio rerio.
TL;DR: The zebrafish genome contains at least seven vtg genes (vtg1-7) encoding heterogeneous vitellogenins with three distinct types of Vtgs, and in situ hybridization experiments confirmed that the extrahepatic expression was actually in adipocytes associated with several organs such as the intestine, ovary, and E2-induced testis.
Journal ArticleDOI
Estrogen deficiency, obesity, and skeletal abnormalities in follicle-stimulating hormone receptor knockout (FORKO) female mice.
Natalia Danilovich,P. Suresh Babu,Weirong Xing,Maria Gerdes,Hanumanthappa Krishnamurthy,M. Ram Sairam +5 more
TL;DR: The phenotypes evident in these genetically altered FSH-R mutants may provide an experimental system to explore the effects of estrogenic compounds on different targets including the ovary in a nonsurgical setting.
Journal ArticleDOI
Role of Sertoli cell number and function on regulation of spermatogenesis.
TL;DR: Roles of Sertoli cells in regulation of spermatogenesis are discussed and methods for estimating the number of SERToli cells, in a testis, that overcome the problems (assumptions) associated with the indented, pear-shaped of S Bertoli cell nuclei which make it difficult to estimate the volume of individual nuclei are discussed.
Journal ArticleDOI
The origins of the vertebrate hypothalamic-pituitary-gonadal (HPG) and hypothalamic-pituitary-thyroid (HPT) endocrine systems: new insights from lampreys.
TL;DR: The results obtained by analysis of the HPG/T axes in sea lamprey may transcend the limited scope of the corresponding physiological compartments by providing important clues in respect to the interplay between genome-wide events (duplications), coding sequence (mutation) and expression control level evolutionary mechanisms in definition of the chemical control pathways in vertebrates.

Seasonal breeding:nature's contraceptive.
G A Lincoln,Roger V. Short +1 more
TL;DR: The seasonal cycle highlights the seasonal changes in daylight length, rutting behavior, testicular diameter, sexual skin flush, and concentrations of plasma follicle-stimulating hormone, prolactin, and testosterone in a group of rams throughout the year.
Journal ArticleDOI
The physiological responses of anovulatory ewes to the introduction of rams: a review.
TL;DR: Ewes of many breeds can be stimulated to ovulate by the reintroduction of rams and appear to be effected both through a delay in the onset of the LH surge and through a direct action of progesterone on the ovary.
Journal ArticleDOI
Factors affecting the secretion of luteinizing hormone in the ewe.
TL;DR: LH is secreted as discrete pulses throughout all stages of the reproductive cycle of the ewe, including pre‐pubertal, seasonal and lactational anoestrus, and the luteal and follicular phases of the oestrous cycle.
Nutritional influences on reproduction in mature male sheep and goats
TL;DR: In this article, it was shown that nutritional signals exert powerful effects on the reproductive system of mature male ruminants, and the responses are partly independent of changes in gonadotrophin secretion.
