(2002)Intracellular reactive iron is a source of free radicals and a possible cause of cell damage. In this study, we analyzed the changes in iron homeostasis generated by iron accumulation in neuroblastoma (N2A) cells and ...
-
(2002)Breast cancer is the most common malignancy among women. Chilean studies reveal that this cancer presents the third highest mortality rate. A family history of breast cancer is one of the major risk factors for the development ...
-
(2001)The mechanism and site of action of Ca2+ at the recombinant murine 5-hydroxytryptamine (5-HT)3A receptor were investigated using whole-cell voltage clamp, radioligand binding and single-cell Ca2+ imaging. Inhibition of the ...
-
(BC Decker Inc., 2002)Objectives: A combination vaccine against hepatitis A and B provides the opportunity for simultaneous protection against both diseases with a single vaccine. This clinical study investigated the reactogenicity and ...
-
(Pan American Health Organization, 2002)Objectives. To estimate the magnitude of geographical health inequalities in Chile through key indicators based on data and information that are routinely collected and easily obtained, and to characterize the current ...
-
(Society of Biology of Chile, 2002)The aim of the present study was to study the trypanocidal activity of nanoparticles loaded with nifurtimox in comparison with the free drug against Trypanosoma cruzi, responsible for Chagas' disease. Ethylcyanoacrylate ...

(2002)We describe a case in which telesurgical consultation from Tampa, Florida, USA was used to accomplish operative fetoscopy in Santiago, Chile for the treatment of a twin pregnancy involving an acardiac twin. The procedure ...
-
(Society of Biology of Chile, 2002)Potassium depolarization of cultured muscle cells was employed to study cellular responses linked to calcium signaling. Events occurring after depolarization include i) A transient increase of the IP3 mass (2-10s); ii) A ...
-
(2002)Protein kinase CK1 (previously known as casein kinase I) conforms to a subgroup of the great protein kinase family found in eukaryotic organisms. The CK1 subgroup of vertebrates contains seven members known as α, β, γ1, ...

(2002)Objective: We tested the hypothesis that exercise induces myocardial preconditioning in dogs. Methods: We instrumented dogs with a snare on the anterior descending coronary artery and catheters in the root of the aorta, ...
-
(2002)Aims/hypothesis. Insulin resistance with increased risk of Type II (non-insulin-dependent) diabetes is a common feature of polycystic ovary syndrome (PCOS). To investigate antecedents of metabolic disorders in family members ...
-
(Birkhauser Verlag Basel, 2002)Objectives: Kupffer cells, liver macrophages involved in immunomodulation, phagocytosis, and biochemical attack, can induce cytotoxicity and inflammation when their activity is exacerbated. The aim of this study was to ...
-
(2002)The transport of lysine has been investigated in epithelial cells isolated from chicken jejunum. The kinetics of lysine transport and the pattern of interaction with zwitterionic amino acids were consistent with system ...
-
(2002)The class II transactivator (CIITA) controls both the constitutive and IFN-γ inducible expression of HLA-D genes. In addition, through the squelching of another transactivator CREB-binding protein, CIITA was more recently ...
-
(2002)β2-Glycoprotein I (β2GPI) is known to influence macrophage uptake of particles with phosphatidylserine containing surfaces, as apoptotic thymocytes and unilamellar vesicles in vitro. Nevertheless, effects upon macrophage ...
-
(Rockefeller University Press, 2001)A mutation in the gene encoding for the liver mitochondrial aldehyde dehydrogenase (ALDH2-2), present in some Asian populations, lowers or abolishes the activity of this enzyme and results in elevations in blood acetaldehyde ...
-
(Intern. and American Associations for Dental Research, 2002)Pregnant women with periodontal disease (PD) may be at increased risk for having preterm low-birth-weight (PLBW) children. We investigated whether the maintenance of the mothers' periodontal health after 28 weeks' gestation ...
-
(Elsevier Limited, 2001)There is little knowledge about Latin American social medicine in the English-speaking world. Social medicine groups exist in Argentina, Brazil, Chile, Colombia, Cuba, Ecuador, and Mexico. Dictatorships have created political ...
-
(2002)There is increasing evidence that certain microbial agents may have an etiopathogenic role in the development of atherothrombosis. Helicobacter pylori, a bacterium that causes peptic ulcer disease, has been suggested as ...
-
(2001)The involvement of cytosolic nitric oxide (NO) and mitochondrial superoxide radical (O2 ·-) production was evaluated as a mechanism triggering liver oxidative stress in lindane (40 mg/kg) or L-3,3′,5-triiodothyronine (T3, ...
