(Endocrine Society, 1998)This study tested the hypothesis that the fetal llama, a species adapted to the chronic hypoxia of life at high altitude, demonstrates a potent carotid chemoreflex influence on adrenocortical responses during acute hypoxemia. ...
-
(1998)The frequency of astrovirus infection in 456 Chilean children with diarrhea was determined by enzyme-linked immunosorbent assay, reverse transcriptase PCR, and cell culture. Astrovirus was detected in 16.5% of rotavirus-negative ...
-
(1998)A total of 12 women (24.2 ± 1.6 years old, BMI 36.7 ± 1.5 Kg/m2) with hyperandrogenism (HA) and with normal glucose tolerance test were studied to evaluate the involvement of endogenous opioids in the pathophysiology of ...
-
(1998)Thiobacillus ferrooxidans is one of the chemolithoautotrophic bacteria important in industrial biomining operations. During the process of ore bioleaching, the microorganisms are subjected to several stressing conditions, ...
-
(1997)Psychological risk factors in borderline personality disorder is reviewed. It's concluded that development of borderline psychopathology is most readily accounted for by any single psychological risk factor or even by ...
-
(1998)The properties of the Na/K pump and Na, K, Cl cotransporter were studied in vascular tissue of two-kidney Goldblatt hypertensive rats. These transport systems were measured as ouabain-sensitive and bumetanide-sensitive ...
-
(1998)Open choledochostomy still represents an important step of biliary surgery, even during the era of laparoscopic surgery. Although its application has decreased with the widespread use of endoscopic retrograde cholangiopa ...
-
(1998)Ethanol may alter the homeostasis of water and electrolytes before the occurrence of liver damage able to explain these disorders. How the kidney may become involved in water diuresis or sodium and potassium retention has ...
-
(1998)The effect of replacement of gene 11 of rotavirus SA-11 by a gene carrying a head to tail duplication obtained from a swine rotavirus strain was studied. The swine rotavirus strain with a duplicated gene (CC86) exhibits ...
-
(1998)Objective: To describe the importance of tension-type headache (TTH) in Santiago, Chile, by analyzing its prevalence, clinical features, and impact by age, gender, and socioeconomic status, using widely accepted international ...
-
(Brazilian Journal of Genetics, 1998)Oligonucleotide probes (GATA)4 and (GGAT)4 for minisatellite loci produced DNA fingerprinting patterns which are unique in individual rainbow trout. These patterns can be used to monitor the efficiency of manipulation of ...
-
(1998)We have studied chorionic villi from 38 placentae obtained from spontaneous abortions at 7 to 12 weeks of pregnancy. Samples were separated into four groups: (1) early normal (7-9 weeks of pregnancy, normal karyotype); (2) ...
-
(1997)The neurodevelopmental hypothesis of schizophrenia states that the disease is associated with abnormal brain development. This defect predisposes to a characteristic pattern of brain malfunction in early adult fife and to ...
-
(Lippincott Williams and Wilkins, 1998)The indications for routine intraoperative cholangiography remain controversial. We present here our recent results concerning the frequency of unknown retained common bile duct stones in 253 consecutive patients who ...
-
(1998)4F2hc is an almost ubiquitous transmembrane protein in mammalian cells; upon expression in Xenopus laevis oocytes, it induces amino acid transport with characteristics of system y+L. Indirect evidence fostered speculation ...
-
(1998)We investigated the effects of the drug 14-keto-stypodiol diacetate (SDA) extracted from the seaweed product Stypopodium flabelliforme, in inhibiting the cell growth and tumor invasive behavior of DU-145 human prostate ...
-
Rapid kinetic studies of SH oxidation-induced calcium release from sarcoplasmic reticulum vesicles (Academic Press Inc., 1997)We studied the kinetics of calcium release induced by SH oxidation in triads isolated from frog and rabbit skeletal muscle by measuring calcium fluxes by a fast filtration method. In both species SH oxidation induced release ...
-
Renal transplant and chronic rejection in pediatrics Trasplante renal y rechazo crónico en pediatría (1998)The rapid advances in immunobiology, pharmacology and molecular biology have made successful renal transplantation the optimal therapeutic modality for adults and children, reaching a near -90% of patient-graft survival ...
-
(1997)The influence of acute ethanol administration on the oxidative stress status of rat brain and liver was assessed by in situ spontaneous organ chemiluminescence (CL). Brain and liver CL was significantly increased after ...
-
(1997)This study tested the hypothesis that in the llama fetus changes in cerebral blood flow are closely associated with changes in cerebral oxidative metabolism such as occur during transitions between electrocortical states. ...
