The transport of alpha-ketoglutarate (alpha-KG) across the luminal membrane of the rat nephron was studied by micropuncture and microassay techniques. In normal and acidotic rats, approximately 75% of…
Recently it has been observed that Ca excretion in laboratory rats does not follow a Gaussian distribution, with approximately 10% of them excreting Ca at a rate of 2 SD above the group mean. This phe…
Since hyperprolactinemia was found to induce osteopenia in the metaphysis of long bone in non-mated female rats, pregnant and lactating rats with sustainedly high plasma prolactin (PRL) levels might a…
A series of studies has shown that long-term infusion of insulin and glucose does not increase mean arterial pressure (MAP) in dogs, but we have shown that the same infusion protocol or infusion of gl…
The time course of plasma corticosterone was measured in male Sprague-Dawley rats whose endogenous release of ACTH had been blocked following rapid i.v. injections of doses ranging from 0.003 to 10 mi…
Glucose tolerance tends to decrease in healthy aged subjects without family history of diabetes. Either reduced insulin secretion or insulin resistance may be responsible. Insulin secretion and insuli…
Circadian plasma melatonin secretion patterns were determined in 12 healthy men over 3 consecutive 24-hour periods. The rhythms showed marked intra-individual stability, but pronounced interindividual…
The existence of a circadian rhythm of atrial natriuretic peptide (ANP) in humans is controversial. We studied the plasma ANP response to isotonic blood volume expansion in the morning and in the afte…
The plasma concentrations of vasoactive intestinal polypeptide and prolactin were measured before and after an exhaustive and a submaximal exercise test in 7 male marathon runners. A significant incre…
The particle size distribution and water-soluble inorganic ion (WSII) and carbonaceous species in size-segregated aerosols, Dp < 0.95, 0.95 < Dp < 1.5, 1.5 < Dp < 3.0, 3.0 < Dp < 7.2, and 7.2 < Dp < 1…
Low birthweight is a risk factor for later adverse health. Here the impact of placentally mediated prenatal growth restriction followed by postnatal nutrient abundance on growth, glucose metabolism an…
Patterns of leptin secretion during the estrous cycle and the possible relationship of changes in circulating leptin during the periovulatory period with ovarian function in sows of obese (Iberian bre…
Earlier reports indicate that calves derived from in vitro produced (IVP) embryos are more susceptible to neonatal disease than calves produced after artificial insemination (AI) or natural mating. Th…
At present, it is unclear which exercise-induced factors, such as myokines, could diminish the negative impact of the reduction in pulmonary function imposed by the exercise in question. In this study…
A low-pressure cloud chamber was used for several years to display the tracks created by the passage of ionizing particles through vapors of interest. The spatial distributions of the ions that were f…
Paroxysms of atrial tachycardia are oftentimes associated with polyuria. The plasma levels of the potent diuretic hormone, atrial natriuretic peptide (ANP), are elevated during episodes of atrial tach…
OBJECTIVE: To investigate the effect of cimetidine and probenecid on the renal clearance of pilsicainide in healthy subjects.METHODS: Nine healthy men (age range, 21 to 38 years) were given oral doses…
Four normal male subjects received LHRH by continuous infusion for 72 hrs at 1.4 microgram/min. Mean basal LH was 7.7 +/- 1.0 mIU/ml, increased to a maximum of 120 +/- 22.7 mIU/ml, and then declined t…
This study evaluates the influence of testicular secretions during development in male hamsters on peripubertal gonadotropin levels. Castration or sham operations were performed on the day of birth (D…
Sex-related differences both in the basal secretion of catecholamines and in the adrenergic reactivity to various stimuli have been described. We studied the responses of catecholamines and arterial b…
