Several studies have measured the effectiveness of masks at retaining particles of various sizes in vitro . To identify a functional in vivo model, herein we used germ-free (GF) mice to test the effec…

Abnormalities in the vasopressin and renin systems have been reported in spontaneously hypertensive rats (SHR). Therefore, studies were performed to evaluate the responsiveness of these systems to cha…
Corticoliberine-like activity of the paraventricular nucleus area and median eminence, concentration of plasma 11-oxycorticosteroids and total blood calcium were studied after parathyroidectomy, parat…
Coronary arteriovenous difference in stable end-products of nitric oxide metabolism, nitrate and nitrite, was increased in ischemic canine hearts. In accordance with the reduction of coronary blood fl…
Important kinetic aspects of renin reaction were studied in order to evaluate the parameters that regulate the formation rate of angiotensin I. This rate decreased throughout the incubation period of …
The first objective of this study was to determine whether LH and testosterone respond differently to a naloxone injection in relation to varying sexual performance in rams. If differences occurred, t…
Previously, we have demonstrated the potential of plasma 2-hydroxyglutarate (2HG) as an easily detectable biomarker for skeletal muscle injury in rats. Here, we examined whether plasma 2HG was superio…
Antibodies against infectious laryngotracheitis virus, influenavirus and Newcastle disease virus were not demonstrated. The prevalence of infections caused by adeno- and reovirus in egg-laying flocks …
We inoculated game-farm mallard (Anas platyrhynchos) eggs and 1-day-old birds with Mycoplasma anatis to determine its effect on hatching success and growth rates of ducklings. Inoculations of eggs red…
To assess the possible role of circulating enkephalins in the osmotic release of vasopressin, Met5 (M-Enk)- or Leu5-enkephalin (L-Enk) dissolved in 0.9 or 10% NaCl was infused to either anesthetized o…
Peripheral plasma insulin, growth hormone, and blood glucose were determined in 24 dairy cows during early lactation. Blood samples were obtained at 4-day intervals during the first 56 days of experim…
The present paper assesses the use of the supralittoral amphipod Talitrus saltator as a bioindicator of the effects of human trampling on the supralittoral sandy band. Samplings in delimited areas wer…
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…
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…
Group-living animals commonly display differences in behaviour, physiology and endocrine profiles between conspecifics within the group, which are tightly linked to reproduction. Teleosts exhibit a va…
Using radioimmunoassay we have measured the plasma and amniotic fluid levels of androgen and estradiol in male and female hamster fetuses nearing parturition. On Days 14 and 15 of gestation (day of bi…
During pregnancy, high fat diet (HFD) induces maternal obesity, insulin resistance, and placental inflammatory responses that compromise placental and fetal development. Whether maternal HFD would adv…
A fluorometric assay was used to determine plasma antithrombin III (AT III) activities in 15 healthy adult horses. Nearly all plasma samples had an initial value of greater than 100% thrombin inhibite…
A specific and sensitive homologous radioimmunoassay (RIA) for determination of golden hamster growth hormone (GH) is described and compared to a heterologous hamster GH RIA. Using the homologous syst…
