(SPRINGER, 2006-05)In this study, we used a 16S rDNA-based approach to determine bacterial populations associated with coho salmon (Oncorhynchus kisutch) in its early life stages, highlighting dominant bacteria in the gastrointestinal tract ...
-
(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 ...
-
(Lippincott Williams & Wilkins, 2021)Degeneration of dopaminergic, nigrostriatal neurons is the hallmark of Parkinson disease (PD), and PET quantification of dopamine transporters is a widely accepted method for differential diagnosis between idiopathic ...

(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 ...
-
(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, ...

(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 ...
-
(Amer Physiological Soc., 2016)Calcium signaling through store-operated channels (SOC) is involved in hypoxic pulmonary hypertension. We determined whether a treatment with 2-aminoethyldiphenylborinate (2-APB), a compound with SOC blocker activity, ...
-
(Blackwell, 2016)Elevated intratesticular levels of hydroxyoestradiols and methoxyoestradiols, two classes of endogenous oestradiol metabolites, have been associated with male infertility. The aim of this study was to explore the effects ...
-
(Elsevier, 2013-11)To quantitate 2-methoxyestradiol (2-ME) in human corpus luteum (CL) of different ages and to determine the expression of cytochrome-P450-1A1 (CYP1A1) and catechol-O-methyl transferase (COMT) in CL and the action of 2-ME ...

2-Phenylaminonaphthoquinones and related compounds: Synthesis, trypanocidal and cytotoxic activities (Elsevier, 2014)A series of new 2-aminonaphthoquinones and related compounds were synthesized and evaluated in vitro as trypanocidal and cytotoxic agents. Some tested compounds inhibited epimastigote growth and trypomastigote viability. ...
