(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 ...
-
(1994)The acquisition of serum antirotavirus antibodies among children in day care centers was monitored through two rotavirus seasons. Twenty-six children were monitored daily for diarrhea and weekly for stool rotavirus excretion ...
-
(1994)3β-Hydroxysteroid dehydrogenase (3β-HSD) is one of the key enzymes involved in the steroidogenic pathway of Leydig cells. In this study, quantitative cytochemistry was used to detect the 3β-HSD staining intensity in ...
-
(1994)To evaluate the possible role of captopril during pacing induced ischaemia we studied 7 patients with stable coronary artery disease. Coronary sinus blood levels of thromboxane-B2 (TXB2), prostaglandin-F1 alpha (PGI2), ...
-
(1994)In a study designed to evaluate the genetic variability of adenovirus strains associated with infantile cases of respiratory disease requiring hospitalization, a collection of 136 adenovirus isolates obtained in the Roberto ...
-
(1994)Background. The aims were to determine the prevalence of psychiatric morbidity among primary care attenders in a poor suburb of Santiago and to study the relationship with health service use. Method. A cross-sectional ...
-
(1994)A specific, fast, and sensitive nonradioactive immunobinding assay for the detection and enumeration of the moderate thermophile Thiobacillus caldus and the thermophilic archaeon Sulfolobus acidocaldarius was developed. ...
-
(1994)OBJECTIVE: The purpose of this study was to characterize the mechanisms involved in the placental clearance of hypoxanthine. STUDY DESIGN: Uptake of isotope-labeled compounds was measured in the in situ perfused guinea ...
-
(1994)The steroidogenic capacity and oxidative stress-related parameters of the human corpus luteum (CL) at different stages of the luteal phase were studied under basal and human chorionic gonadotropin (hCG)-stimulated conditions. ...
-
Partial removal of lipopolysaccharide from Thiobacillus ferrooxidans affects its adhesion to solids (1994)Conditions for the partial removal of lipopolysaccharide (LPS) from Thiobacillus ferrooxidans are described. Raising the pH of the solution containing the cells from pH 1.5 to pH 6.8 to 8.0 releases about 50% of the LPS ...
-
(1994)Biologists have believed that the application of statistical or mathematical models to population biology has always been a correct and helpful tool to acquire knowledge. The present article demonstrates that the standard ...
-
(1994)In a study to investigate the ability of chaperones to modulate src kinase activity, it was observed that BiP, a member of the HSP70 family found in the endoplasmic reticulum, is an excellent substrate for src kinase in ...
-
(Springer-Verlag, 1994)Six monoclonal antibodies specific for the major capsid protein of rotavirus, VP6, previously characterized, were tested in a biological assay for their capacity to block the transcriptase activity associated with the ...
-
(1993)In this study we evaluated the effect of several trypsin inhibitors (p-aminobenzamidine: pAB; N-α-p-tosyl-L-lysine-chloromethyl-ketone: TLCK and p-nitrophenyl-p'-guanidino-benzoate NPGB) on sperm binding and penetration ...
-
(1994)A microsomal fraction enriched in ion pump enzymes was isolated from the gill of the carp (Cyprinus carpio Linneo). Mg2+-dependent (Na+ + K+), Na+, HCO-3 and Ca2+-stimulated ATPase activities were studied following treatment ...
-
(1994)The present report describes experiments to evaluate phospholipid methyltransferase activity in golden hamster spermatozoa incubated under different conditions. Washed cauda epididymal sperm were incubated with taurine, ...
-
(1994)Changes in the evolution of a malignant transplantable tumor in mice to whom quinacrine, copper and zinc were supplied in drinking water are reported. Male AJ mice were inoculated in the right thigh with 1,000,000 TA3 or ...
-
(1993)Compaction, a critical event in the early mouse development, constitutes the beginning of trophoblast differentiation. Since compaction is attributed to the increasing in cell adhesion due to the cadherin uvomorulin and ...
-
(1994)The trisomy-16 (TS16) mouse is considered to be a model of human trisomy 21 (Down syndrome) because of genetic homology between mouse chromosome 16 and human chromosome 21. We examined cholinergic function of brain and ...
-
Leucine and Glucose Turnover in Chronic Alcoholics During Early Abstinence and After an Ethanol Load (1993)We studied leucine turnover using a primed infusion of [1‐14C]‐l‐leucine and glucose turnover using a primed infusion of [6‐3H]‐d‐glucose in five alcoholic patients without liver damage and five age‐matched controls. ...
