(2002)Air pollutants in Santiago (33.5°S, 70.8°W, 500m a.s.l.), a city with 5 million inhabitants, located in a basin in Central Chile surrounded by the high Andes, frequently exceed air quality standards. This affects human ...
-
(2002)Complete achromatopsia is genetically heterogeneous and segregates with mutations in CNGA3 or CNGB3 genes, which respectively encode for α- and β-subunits of the cyclic-nucleotide-gated (CNG) cation channel expressed in ...
-
(2002)The cyanobacteria belonging to the genus Nostoc fix atmospheric nitrogen, both as free-living organisms and in symbiotic associations with a wide range of hosts, including bryophytes, gymnosperms (cycads), the small water ...
-

-
(2002)The role of Kupffer cells in the hepatocellular injury and oxidative stress induced by lindane (20 mg/kg; 24h) in hyperthyroid rats (daily doses of 0.1 mg L-3,3′,5-triio-dothyronine (T3)/kg for three consecutive days) was ...
-
(2002)We report a preterm infant with 30 weeks of gestation, that received broad spectrum antimicrobials during the first days of life. At nine days of life, the infant appeared with abdominal distension and hematochezia. A ...

-
(2002)To evaluate the effects of nutritional supplements on nitrogen and energy balances, body composition and immune parameters, HIV-infected malnourished adult outpatients were prospectively studied. Forty-six patients (4 ...
-
(2002)The materno-fetal transfer of metabolites and nutrients requires the operation of specific transport mechanisms through syncytiotrophoblast membranes. Electrophysiological studies on these cells are scarce and, because of ...
-
(2002)Background. Paroxetine has become an effectiveness treatment in anxiety disorders in adults. Despite the fact that this is an especially prevalent psychiatrist disorder in children and adolescents, there are very few studies ...
