(2004)Background and aims: Air displacement plethysmography with the BOD-POD is a new densitometry technique, and has been found to be an accurate method to measure body composition. The aim of this study was to assess body ...
-
Copper neurotoxicity in rat substantia Nigra and striatum is dependent on DT-diaphorase inhibition (2008)The dependence of copper neurotoxicity on DT-diaphorase inhibition was suggested from results obtained from a cell line derived from substantia nigra. Therefore, the aim of this study was to evaluate whether CuSO4 neurotoxicity ...
-
(2004)The aim of this work was to study the mechanisms involved in intestinal permeability of gonyautoxins. For this purpose, the influence on transmucosal resistance of gonyautoxins and their permeability was investigated in ...
-
(2004)Membrane depolarization of skeletal muscle cells induces slow inositol trisphosphate-mediated calcium signals that regulate the activity of transcription factors such as the cAMP-response element-binding protein (CREB), ...
-
(2008)The purpose of this study was to establish if the duration of chip fracture in equine carpal joint of purebred horses, affects the synovial concentration of total glycosaminoglycans (GAGsT) and glycosaminoglycans that are ...
-
(Lippincott Williams and Wilkins, 2008)Background: Severe sepsis is not clinically apparent during the first 24 hours of hospitalization in most children with cancer and febrile neutropenia (FN), delaying targeted interventions that could impact mortality. The ...
-
(2008)Anemia is one of the most common manifestations of Chronic Renal Failure (CRF), specially during the dialysis period. Growth failure and a high cardiovascular morbimortality are 2 of the most important consequences. ...
-
(2008)Background: Validated equations to measure body composition in Chilean preschool children are lacking, since the only international equation available was developed in obese, and undernourished caucasian children. Due to ...
-
(Ediciones Doyma, S.L., 2008)BACKGROUND AND OBJECTIVE: Chronic hemodialyzed patients have a low level of aerobic capacity, caused by the pathologies concomitant to renal insufficiency, according with a low level of physical activity. One of the factors ...
-
(Ediciones Ergon SA, 2008)Introduction. The study of the prevalence of cleft lip and palate and the identification of risk groups helps to improve the treatment of this condition. Occurrence may be prevented by improving environmental conditions ...
-
(2004)Summary: Several applications require the backtranslation of a protein sequence into a nucleic acid sequence. The degeneracy of the genetic code makes this process ambiguous; moreover, not every translation is equally ...
-
(2008)We present a clinical case of a patient who consulted for a cerebelous syndrome and diplopia associated to 10 kg weight loss in six months and multiple adenopathies. Cerebral imagenology study evidenced the presence of ...
-
(2007)Allozyme variability was assessed within and between 18 samples of four chromosomal races of the Liolaemus monticola complex: "Southern, 2n=34", "Northern, 2n=38-40", "Multiple Fission, 2n=42-44" and "Northern modified 1, ...
-
(2008)Background: Acute bacterial meningitis (ABM) is a serious disease that needs rapid diagnosis for an accurate treatment. The most important etiological agents are: Streptococcus pneumoniae, Neisseria meningitidis and ...
-
(Universidad de la Frontera, 2007)Adult rats malnourished prenatally with a low-protein, isocaloric diet showed smaller median fiber diameter of myelinated and unmyelinated fibers and a higher axonal density in the callosal splenium than controls. These ...
-
(2004)In a previous work the involvement of a fenamate-sensitive Ca 2+-activated nonselective cation channel (NSCC) in free radical-induced rat liver cell necrosis was demonstrated (5). Therefore, we studied the effect of radical ...
-
(2004)Background. Myoglobinuric acute renal failure causes increased oxidative stress. Since ethanol upregulates renal antioxidant enzymes and wine polyphenols behave as antioxidants, we tested the hypothesis that red wine ...
-
(2008)Protein kinase CK2 (also known as casein kinase 2) is present in the cytoplasm, nuclei, and several other organelles. In addition, this enzyme has been found bound to the external side of the cell membrane where it acts ...
