(1994)We studied 131,899 consecutive births at the Maternity of the University of Chile Clinical Hospital, finding 4887 newborns with congenital malformations (representing a rate of 37.05 per 1000 alive newborns). Between January ...
-
(1994)The classic concept of a direct pathogenic relationship between high blood pressure and development of left ventricular hypertrophy has been challenged by observations such as the modest correlations between blood pressure ...
-
(1994)The aim of this study was to look for pathological changes in the oral cavity in a group of 40 non cirrhotic male alcoholics, ranging in age from 30 to 40 years old. These subjects were compared with a group of 40 non ...
-
Interhemispheric Structural Asymmetry Induced by a Lateralized Reaching Task in the Rat Motor Cortex (1994)The effects of a lateralized reaching task on the morphological structure of the rat motor cortex were studied during the early postweaning period. Our results show that the consistent use of one forelimb accounts for a ...
-
(1994)New oral contraceptives (OC) with lower estrogen contents are potentially useful for menopausal replacement. An OC with 20 μg ethinyl estradiol and 150 μg desogestrel was used for this purpose in perimenopausal women with ...
-
(1994)The Chilean mine El Teniente is the world's largest underground copper mine. It operates a giant smelter at Caletones (34° 7′ S, 70° 27′ W) and we have found it is the major source of air contamination in the region. In ...
-
(1994)A gene family encoding a set of histone H1 proteins in Trypanosoma cruzi is described. The sequence of 3 genomic and 4 cDNA clones revealed the presence of several motifs characteristic of histone H1 although heterogeneity ...
-
(American Society for Microbiology, 1994)The tyrosyl-tRNA synthetase gene (tyrZ) from Thiobacillus ferrooxidans, an acidophilic, autotrophic, gram-negative bacterium that participates in bioleaching of minerals, was cloned and sequenced. The encoded polypeptide ...
-
(1994)The appearance, cellular distribution, and changes of sugar residues during tooth development in adults of the polyphyodont, Liolaemus gravenhorsti, were investigated by using horseradish–peroxidase–conjugate lectins ...

Active epidemiologic surveillance of tuberculosis Vigilancia epidemiológica activa en tuberculosis. (1994)With 5,000 new active cases each year, tuberculosis in Chile remains as the most important communicable disease in the country. Since the type of control programs are linked to the epidemiologic situation as far as infection, ...
-
(1994)Midazolam is a water-soluble benzodiazepine imide that has been used in recent years to manage status epilepticus (SE). We describe four patients with SE refractory to conventional treatment, whose seizures were controlled ...

Study of nuclear decondensation of the rat spermatozoa by reducing agents during epididymal transit (1994)Summary. Chromatin packing, mostly due to disulfide bond formation, is one important step in epididymal sperm maturation. In this study the in vitro effect of a reducing agent such as thioglycolate (Tg) was tested. ...
-
(Kluwer Academic Publishers, 1994)After the finding of the involvement of the C-terminal moieties of tubulin subunits in the interaction of MAPs, different studies have focused on the substructure of the binding domains for the different MAPs. Current ...
-
(1994)The effect of chymotrypsin inhibitors and substrates on the human sperm acrosome reaction stimulated by the human zonae pellucidae or follicular fluid were evaluated. Motile spermatozoa, selected by a Percoll gradient, ...
-
(1994)The two‐electrode voltage clamp technique was employed to measure end‐plate currents in larval neuromuscular junctions of wild‐type (Canton‐S) and of three different Drosophila Shaker mutants: ShakerKS133, Shaker102 and ...
-
(1994)Thirteen asymptomatic chronic alcoholic patients were studied to investigate the early stages of portal hypertension in alcoholic liver disease and the effects of withdrawal and ethanol on hepatic function and hemodynamic ...
-
(1994)Twenty four hour esophageal pH monitoring was performed in 110 patients, placing a pH electrode 5 cm above the proximal border of the lower esophageal sphincter. This test allows to measure the total lapse in which there ...
-
(1994)Summary. The sperm function of fertile men (control), infertility patients (experimental), and men with varicocele were compared. The bioassays used were the follicular fluid‐induced acrosome reaction, the binding to the ...
-
(1994)The genome of Thiobacillus ferrooxidans contains at least two different repetitive DNA elements. One of these elements, termed IS T2 has been sequenced and shown to exhibit the characteristics of a typical prokaryotic ...
