(2009)Worldwide, rotaviruses are the single most important agents of severe gastroenteritis in infants and young children. Globally, it is estimated that every year rotavirus gastroenteritis causes more than 125 million episodes ...
-
(2009)Background: Considering the high prevalence of obesity among children attending elementary schools, it is important to know the evolution of body weight when these children reach adolescent. Aim: To analyze the changes in ...
-
(2009)Fast synaptic inhibition in the brain is largely mediated by γ-aminobutyric acid receptors (GABAAR). While the pharmacological manipulation of GABAAR function by therapeutic agents, such as benzodiazepines can have profound ...
-
(2009)Background: One of the most serious complications after laparoscopic sleeve gastrectomy (LSG) is gastric leak. Few publications exist concerning the treatment of gastric leak. We sought to determine by way of a prospective ...
-
(2009)Childhood obesity in Chile has been recognized as a public health problem. In 2006, we developed a school-based obesity prevention pilot project to intervene during 5 months preschool and schoolchildren from 1st to 4th ...
-
(2009)Sterol receptor element-binding protein-1c (SREBP-1c) and peroxisome proliferator-activated receptor-α (PPAR-α) mRNA expression was assessed in liver as signaling mechanisms associated with steatosis in obese patients. ...
-
(2010)Energy restriction decreases bone mineral density (BMD), and epidemiological studies suggest that the risk of weight loss-induced bone loss is greater in lean than in heavier individuals. Our goal in this study was to ...
-
(Taylor and Francis Inc., 2009)Endoplasmic reticulum (ER) stress has been extensively described in many protein misfolding disorders including amyotrophic lateral sclerosis (ALS). Adaptation to ER stress is mediated by the activation of an integrated ...
-
(2009)Dynamin 2 (DNM2) is a large GTPase involved in the release of nascent vesicles during endocytosis and intracellular membrane trafficking. Distinct DNM2 mutations, affecting the middle domain (MD) and the Pleckstrin homology ...
-
(2009)Seafood consumption-related diarrhea became prevalent in Chile when the pandemic strain of Vibrio parahaemolyticus serotype O3:K6 reached a region in the south of Chile (Region de los Lagos) where approximately 80% of the ...
-
(2009)The advertisment calls of the recently described frog Eupsophus queulensis (Cycloramphidae) are analyzed, based on recordings of seven males. Eupsophus queulensis emits an advertisment call consisting of a harmonic-rich ...
-
(2009)Background: Mating changes the mode of action of 17beta-estradiol (E2) to accelerate oviductal egg transport from a nongenomic to a genomic mode, although in both pathways estrogen receptors (ER) are required. This change ...
-
(2010)TGF-β1 is a potent inductor of malignance in cancer cells. TGF-β1 stimulates the expression of extracellular matrix degrading proteases, cell migration and it is also involved in the epithelial-mesenchymal transition (EMT). ...
-
(2009)Polycystic ovary syndrome (PCOS) is characterized by the presence of hyperandrogenism and an increased follicular mass probably determined by deregulation of locally produced factors. Anti-Müllerian hormone (AMH) is a ...
-
(2009)Objective: To determine whether longer breastfeeding is associated with higher infant lead concentrations. Study design: Data were analyzed from 3 studies of developmental effects of iron deficiency in infancy: Costa Rica ...
-
ATP released by electrical stimuli elicits calcium transients and gene expression in skeletal muscle (2009)ATP released from cells is known to activate plasma membrane P2X (ionotropic) or P2Y (metabotropic) receptors. In skeletal muscle cells, depolarizing stimuli induce both a fast calcium signal associated with contraction ...
-
(2009)Devices such as Novalung® can be used as a bridge to lung transplantation while waiting for a suitable donor. We report a 50 year-old male with a terminal pulmonary fibrosis and candidate for lung transplantation. He was ...
-
(2009)Background: Improvements in environmental conditions may result in an earlier onset of thelarche. However, its onset is not homogeneous among different population groups. Aim: To assess the relationship between nutritional ...
-
(Mosby Inc., 1998)OBJECTIVE: Our purpose was to determine whether adding antenatal thyrotropin-releasing hormone to prenatal corticosteroids reduces the frequency of respiratory distress syndrome. STUDY DESIGN: A randomized, multicenter, ...
-
(2009)Management of patients with severe respiratory failure is mainly supportive, and protective mechanical ventilation is the pivotal treatment. When conventional therapy is insufficient to improve oxygenation without deleterious ...
