The development of grain-boundary cavitation in hot-pressed A1203 both during flexural creep and tress-free annealing in air has been studied. Creep damage accumulation in driven both by the applied stress, and by internal gas pressure in the cavities. The internal pressure results from gas trapped during hot pressing, and from gas-generating chemical reactions active during testing. At machine...
RUzICKA et al. [1935] prepared a monosuccinic ester of androsterone, of which Prof. Ruzicka sent to us two water-soluble preparations for investigation: (1) the sodium salt and (2) the lithium salt. In the following they will be designated as "w.-s. androsterone". We also received from Prof. Ruzicka a lithium salt of the monosuccinic ester of androsterone-diol, which will be designated as "w.-s...
Excess dietary salt induces a cytochrome P450 arachidonic acid epoxygenase isoform in rat kidneys (Capdevila, J. H., S. Wei, J. Yang, A. Karara, H. R. Jacobson, J. R. Falck, F. P. Guengerich, and R. N. Dubois. 1992. J. Biol. Chem. 267:21720-21726). Treatment of rats on a high salt diet with the epoxygenase inhibitor, clotrimazole, produces significant increases in mean arterial blood pressure (...
To elucidate the contribution of the renin-angiontensin system (RAS) to glomerular injury in salt-sensitive hypertension, we investigated the chronic effects of the angiotensin I-converting enzyme inhibitor cilazapril and the angiotensin II type 1-receptor antagonist (AT1a) TCV-116 in Dahl-Iwai rats. Dahl salt-sensitive (S) rats receiving 8% salt diet for 6 wk were simultaneously treated with c...
Soil salinity affects a large part of the region in Iran. Salinity covers 12.5% oftotal area of the country. Priming of seeds in sodium chloride and water (hydro-priming)has been reported to be a simple technique for enhancing the seedling establishment andgermination performance in the seeds of many crops and small seeded grasses under thestress conditions. Therefore, the aim of this research ...
Hypoxia inducible factor (HIF)-1α-mediated gene activation in the renal medulla in response to high salt intake plays an important role in the control of salt sensitivity of blood pressure. High salt-induced activation of HIF-1α in the renal medulla is blunted in Dahl S rats. The present study determined whether the impairment of the renal medullary HIF-1α pathway was responsible for salt sensi...
OBJECTIVE The comorbidity of excess salt and elevated plasma aldosterone has deleterious effects in cardiovascular disease. We evaluated the mechanisms behind the paradoxical increase in aldosterone biosynthesis in relation to dietary intake of salt. METHODS AND RESULTS Dahl salt-sensitive (Dahl-S) and salt-resistant (Dahl-R) rats were fed a high-salt diet, and plasma and tissue levels of ald...
