-
(1995)The antiviral effect of foscarnet (PFA) on the replication of rotavirus, a member of the Reoviridae, was studied. The pyrophosphate analogue is an effective inhibitor of several viral polymerases acting on the enzyme ...
-
(1995)The recombinant α subunit of protein kinase CK2 (casein kinase 2) from Xenopus laevis is inhibited by the addition of single stranded or double stranded DNA. This inhibition is competitive with the casein substrate, having ...
-
(1995)This is a first-approach study tending to correlate solar radiation and temperature with total particulate matter in Santiago, Chile, a city heavily polluted by this contaminant. Experimental data for monthly average total ...
-
(1995)Abstract: Microtubule‐associated proteins (MAPs) play major regulatory roles in the organization and integrity of the cytoskeletal network. Our main interest in this study was the identification and the analysis of structural ...
-
(1995)The main secondary metabolites of Fabiana imbricata showed toxicity towards the greenbug Rhopalosiphum padi when administered in an artificial diet. A dose‐dependent toxicity was observed for fabiaimbricatan‐15‐oic acid ...
-
(Informa Healthcare, 1995)1. Organic extracts from particulate matter collected in downtown Santiago, Chile, in 1990 were administered to female Wistar rats. 2. Extracts shifted the maximal absorption wavelength P450 spectra of the reduced-CO complex ...
-
(1995)To determine attitudes and practices regarding sexual relations during menstruation and vaginal spotting, a crosssectional descriptive survey was performed at the Instituto de Investigaciones Materno Infantil, Universidad ...
-
(1995)A qualitative and quantitative histological analysis of minor salivary glands was carried out in 60 alcoholics and 20 matched control patients. Minor salivary glands biopsies were obtained and samples were processed for ...
-
(1995)The efficacy of chloral hydrate and midazolam as sleep inductors for electroencephalographic recording (EEG) was compared in 59 children who received either chloral hydrate 50 ± mg ± kg (n: 32) or midazolam 1 mg ± kg (n: ...
-
(Kluwer Academic Publishers, 1995)Microtubule-associated proteins (MAPs) interact with tubulin in vitro and in vivo. Despite that there is a large amount of information on the roles of these proteins in neurons, the data on non-neuronal MAPs or MAPs-related ...
-
(1994)As a contribution to establish the real incidence of cystic fibrosis (CF) and the prevalent mutations in the Chilean population a method for the detection of delta F-508 and R-553X, two of the most frequent mutations ...
-
(1994)Cultured myotubes from rat neonatal skeletal muscle were used to measure intracellular Ca2+ concentration ([Ca2ri) and membrane potentials (Vm) uslng the Indo-l mlcrofluorimetry method and the nystatin perforated membrane ...
-
(Springer-Verlag, 1994)It is well known that the risk of predation affects prey decision making. However, few studies have been concerned with the cues used by prey to assess this risk. Prey animals may use indirect environmental cues to assess ...
-
(National Academy of Sciences, 1994)Isolates of human T-lymphotropic virus type I(HTLV-I) were phylogenetically analyzed from native inhabitants in India and South America (Colombia and Chile) and from Ainu (regarded as pure Japanese descendants from the ...
-
(1993)Although the frequency of infection with the human immunodeficiency virus (HIV) is increasing dramatically in areas where Trypanosoma cruzi is endemic, trypanosomiasis has been rarely reported in persons with HIV infection ...
-
(1994)Oxidative stress-related parameters in rat brain and liver were evaluated following acute (60 mg/kg i.p., 2 and 24 h after dosing) or short-term (1000 ppm in the diet for 90 days) lindane administration. Both treatments ...
-
(American Physiological Society, 1994)1. Sixteen rats were recorded continuously for 3 days using an automated system that detected, quantified, and stored the incidence of cortical delta waves, cortical sigma spindles, hippocampal theta rhythm, and electromyographic ...
-
(1994)Young Drosophila larvae (24-28 and 48-52-h old) show a preference for feeding in dark environments, while older larvae (72-76 h post-hatching) prefer more illuminated environments. Changes in the photoresponse during larval ...
-
(1994)Seeking a relationship between blood groups and successful pregnancy, Linn’s group carried out an analysis using the med- ical records of 11,659 women. They found a significantly higher frequency of bleeding during pregnancy ...
-
(Kluwer Academic Publishers-Plenum Publishers, 1994)Digging behavior of D. melanogaster larvae increases as larval development proceeds. Diallel crosses were made to analyze genetically digging behavior at 72 and 108 h of larval age. Additive and dominance variation was ...
