-
(2011)Noroviruses are implicated in many worldwide institutional, food and waterborne outbreaks each year. Genetic typing of isolates is valuable for monitoring outbreak spread as well as variation in circulating strains. ...
-
(2010)Despite the great impact that the Darwinian theories on organic evolution have had in the development and consolidation of biology as an autonomous scientific discipline, their relevance in social sciences, and particularly ...
-
(2011)Background: HIV-infected individuals have heightened cancer risk. With the advent of highly active antiretroviral therapy (HAART), the frequency of some AIDS-defining cancers (ADC) has decreased although certain non-AIDS-defining ...
-
(2011)Background: Regional differences in stroke mortality rates have been described in Chile. These could be related to the distribution of cardiovascular risk factors, the quality of medical care or socioeconomic status ...
-
(2011)Objective: To determine how the homeostasis model assessment of insulin resistance (HOMA-IR) is related to metabolic risk in a sample of overweight and obese Chilean youths accounting for Tanner stage. Methods: A cross-sectional ...
-
(2011)Potassium channels (K+ channels) are members of one of the largest and most diverse families of membrane proteins, widely described from bacteria to humans. Their functions include voltage-membrane potential maintenance, ...
-
(2011)The revaluation of the Andean cultivations, quinua (Chenopodium quinua Willd) and lupin (Lupinus albus L.), to be used in nutritional mixtures, with traditional cereals like corn (Zea mays L.) and rice (Oryza sativa L.), ...
-
(2011)The study of the correlations that may exist between neurophysiological signals is at the heart of modern techniques for data analysis in neuroscience. Wavelet coherence is a popular method to construct a time-frequency ...
-
(2011)Natural-killer group 2, member D (NKG2D) binds to a variety of ligands, including the major histocompatibility complex (MHC) class I chain-related proteins (MIC) and UL16-binding proteins (ULBP). It is regarded as a ...
-
Genotyping of human papillomavirus in cervical intraepithelial neoplasia in a high-risk population (2011)Infection with the human papillomavirus (HPV) is responsible for 99.7% of cervical cancers, the second most prevalent neoplasia in women worldwide and the fifth leading cause of death by cancer in this population. In Chile, ...
-
(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)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 ...
-
(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)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 ...
-
(2010)Morphometrics is the study of co-variation of biological form and its causes. Its development over the last decades has reached several biological sciences with a traditional descriptive approach, such as morphological ...
-
(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 ...
-
(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 ...
-
(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)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 ...
