The reduction number r(A) of a standard graded algebra A is the least integer k such that there exists a minimal reduction J of the homogeneous maximal ideal m of A such that J m = m. Vasconcelos conjectured that r(R/I) ≤ r(R/ in(I)) where in(I) is the initial ideal of an ideal I in a polynomial ring R with respect to a term order. The goal of this note is to prove the conjecture. 1. Reduction ...

Arginine-vasopressin (AVP) markedly increased basal aldosterone (ALDO) secretion by dispersed zona-glomerulosa (ZG) cells, and its effect was selectively reversed by V1-receptor antagonists (AVP-A1). Corticosterone (B) production by dispersed zona fasciculata (ZF) cells was not affected. The bolus intraperitoneal (i.p.) administration of AVP acutely raised the plasma concentrations of both ALDO...

PURPOSE In peripheral sodium-transporting tissues, the serum- and glucocorticoid-regulated kinase (SGK) isoform-1 is an early corticosteroid target gene in the activation of epithelial sodium channels (ENaCs). Sodium transport across the human ocular nonpigmented and pigmented ciliary epithelial bilayer (NPE-PE) is essential for aqueous humor production, but the expression of SGK1 and ENaC subu...

There are inconsistencies between the in vitro and in vivo effects of thyroid hormone and aldosterone (Aldo) on the development of an amiloride-blockable short-circuit current (SCC) across bullfrog skin [Takada, M., H. Yai, and K. Takayama-Arita. Am. J. Physiol. 268 ( Cell Physiol. 37): C218-C226, 1995]. To address this issue, tadpoles were raised in Aldo + T3. An amiloride-blockable SCC develo...

To generate quantitative data relating to the hypertensive activity of aldosterone, 9 /xg/kg per day (4 times normal) aldosterone (4-ALDO) were infused chronically in both adrenalectomized and intact dogs until steady state conditions were achieved. Mean arterial pressure (MAP) was monitored continuously, 24 hours per day, and daily steady state values for MAP based on approximately 600 sample ...

Reseña crítica del libro Hacer la revolución. Guerrillas latinoamericanas, de los años sesenta a caída Muro, Aldo Marchesi, editado por Siglo XXI Editores Argentina, en el 2019.

To examine if the neuroendocrine link between volume sensing and renal function is preserved in compensated chronic heart failure [HF, ejection fraction 0.29 +/- 0.03 (mean +/- SE)] we tested the hypothesis that intravascular and central blood volume expansion by 3 h of water immersion (WI) elicits a natriuresis. In HF, WI suppressed ANG II and aldosterone (Aldo) concentrations, increased the r...

Wild-type (Agt+/+) and homozygous angiotensinogen deletion mutant (Agt-/-) littermates were placed on normal (NS) or low Na diet (LS) for 2 weeks. Plasma aldosterone levels (P(aldo)) were comparable during NS, and similarly elevated during LS in Agt+/+ and Agt-/-. Moreover, in both, the elevation in P(aldo) was accompanied by marked increase in adrenal zona glomerulosa cells and adrenal P450ald...
