this study explored the effects of gnrh agonist (gnrha) immunity on expression of fshr mrna in pituitary and fshr protein in uteri, and also confirmed its efficacy on uterine development. 42 prepuberty and non cyclic ewes were assigned to 6 experimental groups (eg) during anestrus season. animals in eg-i, eg-ii and eg-iii were subcutaneously injected with 200, 300 and 400 μg alarelin antigens (...

Vascular endothelial growth factor (VEGF) plays an essential role in angiogenesis. This includes developmental angiogenesis as the loss of a single allele is embryonic lethal due to lack of development of endothelial cells. During early development, endothelial cells depend on VEGF for survival and if it is withdrawn, massive apoptosis results. This is not true in adult organisms; withdrawal of...

Sex determination in the nematode C. elegans is dependent on cell-to-cell communication, which appears to be mediated by the predicted membrane protein TRA-2A and the secreted protein HER-1. In XO males, HER-1 is hypothesised to function as a repressive ligand that inactivates the TRA-2A receptor. In XX animals, HER-1 is absent and TRA-2A promotes hermaphrodite development by negatively regulat...

     In this work, for the first time, the rheological properties of nanofluids of lanthania nanoparticles (NPs) in ethylene glycol (EG) as functions of shear rate, volume fraction, and temperature were measured. The results showed that both EG and the nanofluids behave as non-Newtonian fluids at lower shear rates and transform to Newtonian fluids at higher shear rates. The values of viscosity ...

A comparative analysis of geodetic versus seismic moment-rate estimations makes it possible to distinguish between and aseismic deformation, define the style also reveal potential gaps. This has been performed for Egypt where present-day tectonics seismicity result from long-lasting interaction Nubian, Eurasian, Arabian plates. The data used comprises all available geological tectonic informati...

EG-1 is significantly elevated in breast, colorectal, and prostate cancers. Overexpression of EG-1 stimulates cellular proliferation, and targeted inhibition blocks mouse xenograft tumor growth. To further clarify the function of EG-1, we investigated its role in c-Src activation. We observed that EG-1 overexpression results in activation of c-Src, but found no evidence that EG-1 is a direct Sr...

The sexual addiction model enables physicians to understand the self-destructive behavior of patients whose actions may otherwise appear inexplicable. When a person is preoccupied with sex and continues to engage in compulsive sexual activity despite adverse consequences (eg, loss of marriage, job, health, freedom), he or she is a sex addict. Treatment allows sex addicts to stop their compulsiv...
