Fertility hormone in repose

Chevalier Jackson, M.D. (1865-1958): Il ne se repose jamais.

Dynamics at the Angle of Repose: Jamming, Bistability, and Collapse

When a sandpile relaxes under vibration, it is known that its measured angle of repose is bistable in a range of values bounded by a material-dependent maximal angle of stability; thus, at the same angle of repose, a sandpile can be stationary or avalanching, depending on its history. In the nearly jammed slow dynamical regime, sandpile collapse to a zero angle of repose can also occur, as a ra...

Is there a true requirement for follicle stimulating hormone in promoting spermatogenesis and fertility in primates?

Although the role of follicle stimulating hormone (FSH) in regulating ovarian function is well accepted, its need in regulating testicular function of the adult continues to be debated. Sertoli cells of all mammals have FSH receptors and are known to regulate differentiation and transformation of germ cells to spermatozoa. However, there appear to be species and age differences in the way in wh...

Repose: the cost-effective solution for prompt discharge of patients.

Pressure ulcer prevention is expensive and at times difficult to achieve. Formation, or the potential formation, of pressure ulcers can lead to delayed patient discharge, particularly when the appropriate equipment is unavailable on the day of discharge. This article reviews the potential of Repose, an inflatable mattress overlay, to be an inexpensive and clinically effective alternative to alt...

Endogenous hormone response and fertility in dairy heifers treated with norgestomet and estradiol valerate.

Seventy postpuberal dairy heifers were assigned to remain untreated (n = 26) or to receive the Syncro-Mate-B (SMB) treatment (n = 44). Untreated heifers were inseminated at 12 hr after detection of estrus, while SMB-treated heifers were inseminated either at 48 hr after implant removal (group 1) or at 12 hr after detection of estrus (group 2). Jugular blood was collected at regular intervals fr...
