Hormetic responses of thyroid hormone calorigenesis in the liver: Association with oxidative stress (2010)Thyroid hormone (L-3,3',5-triiodothyronine, T3) exerts calorigenic effects by accelerating mitochondrial O2 consumption through transcriptional activation of respiratory genes, with consequent increased reactive oxygen ...
-
(2010)Objectives: Efavirenz is extensively metabolized by CYP2B6, and associations between CYP2B6 polymorphisms and plasma efavirenz exposure have been reported. The objective of this study was to investigate CYP2B6 haplotype ...
-
(2010)The changes in endometrial homeostasis found in women with polycystic ovarian syndrome (PCOS) could be associated with alterations in the intracrine metabolism of steroid hormones. The uptake of dehydroepiandrosterone-sulphate ...

(2010)The pathways leading to male germ cell apoptosis in vivo are poorly understood, but are highly relevant for the comprehension of sperm production regulation by the testis. In this work, we show the evidence of a mechanism ...
-
(Springer New York, 2010)The double-strand break (DSB) DNA repair pathway has been implicated in breast cancer (BC). RAD51 and its paralogs XRCC3 and RAD51D play an important role in the repair of DSB through homologous recombination (HR). Some ...

(2010)This study was conducted to determine the types of M. pneumoniae prevalent in adults presenting with community-acquired pneumonia during an epidemic period, and to scrutinize a variable region of the RepMP4 element for the ...
-
(2010)Based on association and sequencing studies, investigators have postulated muscle segment homeobox 1 (MSX1) as a strong candidate gene involved in the causation of nonsyndromic cleft lip with or without cleft palate (NSCLP). ...
-
(Universidad de la Frontera, 2009)At present it is not clear if male fertility is affected by intermittent hypobaric hypoxia (IHH). This is an important issue since a large human population works over 3000 masl. This study analyzes epididymal sperm, in ...
