(2010)On the occasion of meeting the first two years of life, it makes a review of SILAT as scientific and educational program that serves as a tool to analyze and solve the problems of morphological medical terminology in the ...
-
(2010)Neuroendocrine tumors are uncommon, including VIPoma that produces vasoactive intestinal polypeptide. We report a 45-year-old female presenting with a history of diarrhea lasting three months. An abdominal CAT scan showed ...
-
(2011)Soluble amyloid β-peptide oligomers (AβOs), increasingly recognized as causative agents of Alzheimer's disease (AD), disrupt neuronal Ca2+ homeostasis and synaptic function. Here, we report that AβOs at sublethal concentrations ...
-
(2011)Neuronal electrical activity increases intracellular Ca2+ concentration and generates reactive oxygen species. Here, we show that high frequency field stimulation of primary hippocampal neurons generated Ca 2+ signals with ...
-
(2011)Calcium ion is a highly versatile cellular messenger. Calcium signals-defined as transient increments in intracellular-free calcium concentration-elicit a multiplicity of responses that depend on cell type and signal ...
-
(2010)Ever since the distinction between praecox dementia and manic-depressive illness made by Kraepelin in 1899, many changes have occurred in the way these conditions and especially their boundaries are conceived. The clearest ...
-
(2010)Chagas disease must be treated in all its stages: acute, indeterminate, chronic, and initial and middle determinant chronic, due to the fact that DNA of the parasite can be demonstrated by PCR in chronic cases, where optical ...
-
(2011)β-Catenin is a key protein in the canonical Wnt signaling pathway and in many cancers alterations in transcriptional activity of its components are observed. This pathway is up-regulated by the protein kinase CK2, but the ...
-
(Springer New York LLC, 2010)Objective Bariatric surgery in morbidly obese patients with type 2 diabetes results systematically in adequate glycemic control, normalization of insulinemia, and a decrease in glycosylated hemoglobin, effects that appear ...
-
(2011)Airway inflammation is a common condition where glucocorticoids (GC) are a well-established therapy. It has been demonstrated that GC stimulate components of innate immunity. Specifically, GC up-regulate TLR2 expression ...
-
(2011)Objective. To identify residential parameters that characterize the physical and social environment in Chile's irregular settlements, and to construct typologies that will allow to develop profiles with those distinctive ...
-
(Elsevier Ltd, 2011)Objective: Congenital adrenal hyperplasia (CAH) is an uncommon syndrome which represents a therapeutic challenge. We analyzed the role of bilateral simultaneous laparoscopic adrenalectomy in the management of CAH. Material ...
-
(2011)Background: Novel molecular insights have suggested that ghrelin may be involved in the pathogenesis of some forms of short stature. Recently, growth hormone secretagogue receptor (GHSR) mutations that segregate with short ...
-
(2010)Inadequate umbilical blood flow leads to intrauterine growth restriction, a major killer in perinatal medicine today. Nitric oxide (NO) is important in the maintenance of umbilical blood flow, and antioxidants increase NO ...
-
(2010)Background: Secondhand smoke (SHS) is an established cause of morbidity and mortality among non-smokers. The workplace is an important source of exposure, especially among workers of restaurants, bars and nightclubs. Aim: ...
-
(2010)From 3D seismic-structural interpretations and well data integration, a set of inverted structures were identified, which allowed to establish the relationships between extensional and compressional deformation in the ...
-
(2010)Background: Semen analysis is one of the parameters used to predict male fertility. Semen can be altered by environmental pollutants; therefore it could be used as a biological marker of exposure in contaminated areas. ...
-
(Maney Publishing, 2011)This study compares the effect of tooth clenching and grinding on sternocleidomastoid electromyographic (EMG) activity during different laterotrusive jaw posture tasks. The study included 28 healthy subjects with natural ...
-
(2010)The Copenhagen Accord (December 2009) underlines that climate change is one of the greatest challenges of our time and emphasizes the political will to urgently combat it, in accordance with the principle of common but ...
-
(2010)Currently, obesity is considered a low chronic inflammatory state. The alterations that occur into the expanding adipose tissue parallel the ones seen in a classic inflammatory process. However, the stimulus that triggers ...
