-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(1986)Since both aldosterone and glucocorticoids increase cation transport in rat distal colon, and a specific glucocorticoid high affinity cytosolic receptor has been indentified in this tissue, it was possible that the action ...
-
(1986)Bioelectrical responses evoked in the ventrolateral funiculus (VLF) of the spinal cord by electrical stimulation of the contralateral hind limb were studied following topical application of 1% morphine solution to the ...
-
(1986)Transverse tubule vesicles were isolated from frog skeletal muscle by a procedure initially described by Rosemblatt (J. Biol. Chem. 256, 8140-8148 (1981)) and later modified by Hidalgo (J. Biol. Chem. 258, 13937-13945 ...
-
(1986)Anxiety and hostility scores (Gottschalk-Gleser method of verbal content analysis) were studied in a mixed patient sample comprising psychosomatic, functional, and neurotic patients under two speech-eliciting conditions: ...
-
(1986)N-Methyl-dl-aspartate, l-glutamate, kainate and dl-homocysteate were found to increase the initial rate and the maximal uptake of 45Ca into the non-inulin space of rat brain cortex slices incubated in vitro. The ...
-
Effect of angiotensin II, ATP, and ionophore A23187 on potassium efflux in adrenal glomerulosa cells (1986)Angiotensin II stimulus on perifused bovine adrenal glomerulosa cells elicited an increase in 86Rb efflux from cells previously equilibrated with the radioisotope. When 45Ca fluxes were measured under similar conditions, ...
-
(1986)Purified human pararotavirus obtained from stool samples from a 6-month-old infant was characterized. Electron microscopy of the viral particles subjected to different treatments suggested that the protein shells differed ...
-
(1986)In urethane anesthetized rats, intravenous administration of a bolus of acetaldehyde (diluted 50 times its volume in Ringer Locke solution) induced after a latency of about 1 second, a triple reflex response characterized ...
-
(1986)Net K fluxes in in vitro suspensions of sliced rat brain cortex were studied by means of a K-sensitive electrode. When incubation was in 3 mM K, a net K efflux occurred. It could be resolved into two first-order rate ...
-
(1986)The bioavailability of iron added to different types of cows' milk formulas was studied using mono-isotopic and double-isotopic methods in 396 infants aged 5-18 mo. All the milk formulas were fortified with ferrous sulfate ...
-
(1986)Marked differences in the activities of three monovalent cation transport systems in horse versus human erythrocytes are reported. Whereas horse erythrocytes exhibit a 6-fold higher sodium-lithium countertransport, the ...
-
(1985)Nineteen hypocupremic marasmic infants 5-14 months of age with a normal wt/1gth ratio, were immunologically evaluated during their rehabilitation. The infants were studied 2-3 months after admission to a Closed Nutritional ...
-
(1986)The analysis of simultaneous unitary neuronal activity related to eye movement and recorded in both superior colliculi has shown a mirror-functioning image. Increase of the frequency discharge in a collicular unit, was ...
