11β-hydroxysteroid dehydrogenase type-2 and type-1 (11β-HSD2 and 11β-HSD1) and 5β-reductase activities in the pathogenia of essential hypertension
(2010)Cortisol availability is modulated by several enzymes: 11β-HSD2, which transforms cortisol (F) to cortisone (E) and 11β-HSD1 which predominantly converts inactive E to active F. Additionally, the A-ring reductases (5α- and ... -
16S rDNA-based analysis of dominant bacterial populations associated with early life stages of coho salmon (Oncorhynchus kisutch)

17-beta-Estradiol upregulates COX-2 in the rat oviduct
(ELSEVIER, 2006-09)We investigated the regulation of cyclooxygenase-2 (COX-2) by 17-beta-estradiol (E-2) in the rat oviduct. We observed that COX-2 is expressed mainly in proestrous and estrous stages, periods under estrogenic influence. ... -

(2011)Background: A polymorphism located in the promoter region (-174 G / C) of interleukin 6 (IL-6) has been linked to early onset of type 1 diabetes (T1D) and increased body mass index (BMI). Aim: To evaluate the possible ... -
1st sexual intercourse and 1st pregnancy in puerperal women at a hospital of the metropolitan area Primera relación sexual y primer embarazo en puérperas de un hospital de la región Metropolitana.
(1995)One thousand women hospitalized at a maternity were surveyed after their delivery or abortion about their first sexual intercourse and pregnancy. Mean age at the first sexual intercourse was 18.7 years and only 9.2% used ... -
2 solutions for estimating odds ratios with zeros Dos soluciones para la estimación de "odds ratios" con ceros.
(1993)Two solutions are proposed for the estimation of odds ratios (OR) when one or the two elements of the principal (A, D) or secondary (B, C) diagonals of a 2 x 2 matrix (A, B, C, D) are 0. The OR estimate is AD/BC. If A or ... -
2,2'azo-bis-amidinopropane as a radical source for lipid peroxidation and enzyme inactivation studies
(Informa Healthcare, 1991)1. 2,2'Azo-bis-amidinopropane (ABAP) thermal decomposition produces free radicals that initiate the lipid peroxidation of erythrocyte ghost membranes. 2. Addition of 6-n-propyl-2-thiouracil decreases the rate of the process, ... -
2,3-butanedione monoxime affects cystic fibrosis transmembrane conductance regulator channel function through phosphorylation-dependent and phosphorylation-independent mechanisms: The role of bilayer material properties
(AMER SOC PHARMACOLOGY EXPERIMENTAL THERAPEUTICS, 2006-12)2,3-Butanedione monoxime (BDM) is widely believed to act as a chemical phosphatase. We therefore examined the effects of BDM on the cystic fibrosis transmembrane regulator ( CFTR) Cl- channel, which is regulated by ... -
2-Aminoethyldiphenylborinate modifies the pulmonary circulation in pulmonary hypertensive newborn lambs partially gestated at high altitude
(American Physiological Society, 2016)© 2016 the American Physiological Society. Calcium signaling through store-operated channels (SOC) is involved in hypoxic pulmonary hypertension. We determined whether a treatment with 2-aminoethyldiphenylborinate (2-APB), ... -
