-
(2013)A sufficient condition on the fractional integral of the absolute value of a function is given in this paper, which allows to assure the convergence of the function to zero. This result can be useful to assure the convergence ...
-
(1987)A total of 516 Escherichia coli strains randomly isolated from coprocultures of 154 Chilean children with diarrhea and 66 controls were examined with DNA probes and tested for adherence to HEp-2 cells. Three adherence ...
-
(1987)Polylysine-containing peptides are found to affect membrane protein kinases, phosphatidylinositol kinases, and adenylate cyclase. Poly(L-lysine), poly(D-lysine), random copolymers of lysine and serine or lysine and alanine, ...
-
(1987)Supernatant of rat heart homogenates obtained by centrifugation at 700 × g for 10 min, incubated in the presence of ethanol (25 and 50 mM) and glucose (10 mM) were found to oxidize ethanol to acetaldehyde (AcH) in such a ...
-
(1987)The administration of isoproterenol induces DNA-synthesis mitosis and growth (increase in size) responses in mouse parotid glands. Both responses were uncoupled by means of daily stimulations with isoproterenol in such a ...
-
(1986)In this study we examined the possible inductive role of the dental papilla from polyphyodont lizard tooth germs. Flank skin sheets of quail ectoderm enzymatically separated from dermal tissue were recombined with lizard ...
-
(1987)Sulphobromophthalein (BSP) retention and liver glutathione levels were studied in uncomplicated hyperthyroid patients. BSP retention was increased in 52.5% of the subjects at admission (n = 40) and in 28% of the cases after ...
-
(1986)Basilar membrane (BM) velocity was measured at a site 3.5 mm from the basal end of the chinchilla cochlea using the Mossbauer technique. The threshold of the compound action potential recorded at the round window in response ...
-
(1987)We describe a quantitative method for determination of iron in stool to monitor consumption of iron-fortified milk in infants. The method is simple, fast, and inexpensive. Stool samples from infants consuming fortified ...
-
(1986)Fetal card iorespiratory changes during spontaneous prelabor uterine contractions (called contractures) were studied in 12 chronically catheterized fetal sheep at 120 to 143 days' gestation. During contractures the carcass ...
-
(1986)The inner protein shell of human rotavirus consists of a single polypeptide called VP6 which was removed from the single-shelled virus by treatment with CaCl2, leaving the viral core. The core thus obtained was unable to ...
-
(1986)Rat brain cortex synaptic vesicles have been isolated by 3 different procedures. The one of Hata et al. (J. Neurochem., 27 (1976) 139) gave synaptic vesicles with a high glutamate content, but also, as judged by [3H]ouabain ...
-
(Martinus Nijhoff/Dr. W. Junk Publishers, 1986)Tissue culture techniques have been developed for studying the influence of hormones on human breast tissues. The present study demonstrated that estrogen induced a highly significant increase in3H-thymidine incorporation ...
-
(1986)The diameters of the zones of inhibition of consecutive clinical isolates around antibiotic susceptibility test discs at medical centres in different parts of the world were computer filed and analysed by a series of ...
-
(1986)Low-frequency stimuli (40-to 1000-Hz tones) have been used to correlate the motion of the 8-to 9-kHz place of the chinchilla basilar membrane with the cochlear microphonics recorded at the round window and with the responses ...
-
(Informa Healthcare, 1986)The effect of early postnatal malnutrition on the responsiveness of the rat prefrontal cortex was studied by determining excitability thresholds and fatigability to direct cortical stimulation. Malnutrition imposed during ...
-
(1988)Rat spermatogenic cells have glycolytic rates of 124 ± 36 nmol lactate · mg protein -1 · h-1. Maximum glycolytic rates in the absence of oxidative phosphorylation do not exceed the basal rates by>40%. From the rates of ...
