1. Glycosaminoglycan distribution in the rat uterine cervix during the estrous cycle
OBJECTIVE: To analyze the amount of glycosaminoglycans in the uterine cervix during each phase of the rat estrous cycle. DESIGN: Based on vaginal smears, forty female, regularly cycling rats were divided into four groups (n = 10 for each group): GI - proestrous, GII - estrous, GIII - metaestrous and GIV - diestrous. Animals were sacrificed at each phase of t

2. Avaliação das concentrações de testosterona no pêlo de cães domésticos (Canis lupus familiaris) / Evaluation of testosterone concentrations in domestic dogs hair (Canis lupus familiaris)
O objetivo do presente estudo foi determinar as concentrações de testosterona no pêlo de cães domésticos, testar dois protocolos diferentes de extração hormonal, comparar os níveis séricos e avaliar as possíveis diferenças de concentração de testosterona no pêlo de acordo com: o sexo; animais castrados e inteiros; região de colheita; tipo e te

3. Estudo da expressão dos receptores do peptídeo insulinotrópico dependente de glicose (GIPR) e do hormônio luteinizante (LHCGR) em tumores e hiperplasias do córtex adrenal / Expression Study of Glucose-dependent insulinotropic peptide receptor (GIPR) and luteinizing hormone receptor (LHCGR) in adrenocortical tumors and hyperplasia
Introduction: The glucose- dependent insulinotropic peptide receptor (GIPR) and luteinizing hormone receptor (LHCGR) are G-protein coupled receptors with a wide tissue expression pattern. The aberrant expression of these receptors has been described in cases of ACTH-independent macronodular adrenal hyperplasia (AIMAH) and in some adenomas, resulting in the i

4. Extraction and immunochemical characterization of cholecystokinin-like peptides from pig and rat brain.
Two major classes of immunoreactive cholecystokinin peptides (iCCK) have been identified in rat and pig brains: (i) large basic peptides (big iCCK) resembling the 33-amino acid porcine cholecystokinin (pCCK33) in size and charge; (ii) small acidic peptides (small iCCK) resembling the COOH-terminal fragments of CCK. Boiling 0.1 M HCl maximally extracts big iC

5. Hormonal modulation of cyclic adenosine 3',5'-monophosphate-dependent protein kinase activity in rat renal cortex. Specificity of enzyme translocation.
Many of the intracellular actions of cyclic adenosine 3',5'-monophosphate are expressed through phosphorylation reactions mediated by cAMP-dependent protein kinases, but little is known about hormonal control of endogenous protein kinase activity (PK) in kidney. In the present study, we examined the effects of parathyroid hormone, glucagon, and isoproterenol

6. A 90-kD Phospholipase D from Tobacco Binds to Microtubules and the Plasma Membrane
The organization of microtubule arrays in the plant cell cortex involves interactions with the plasma membrane, presumably through protein bridges. We have used immunochemistry and monoclonal antibody 6G5 against a candidate bridge protein, a 90-kD tubulin binding protein (p90) from tobacco BY-2 membranes, to characterize the protein and isolate the correspo

7. Quantitation of extrathyroidal conversion of l-thyroxine to 3,5,3′-triiodo-l-thyronine in the rat
Studies of the rate of extrathyroidal conversion of thyroxine (T4) to 3,5,3′-triiodo-L-thyronine (T3) were carried out in rats. Total body homogenates were prepared and extracted with ethanol 48, 72, and 96 hr after the intravenous injection of 125I-T4. 131I-T3 was added, and the paper chromatographic purification of T3 was effected by serial elution and r

8. Calcium transport across the isolated dually perfused human placental lobule.
1. Movements of 45Ca and 3H2O in maternal to fetal (M----F) and fetal to maternal (F----M) directions across the dually perfused isolated human placental lobule were measured under steady-state conditions. 2. M----F values of the clearances (CR) and extractions (ER) of 45Ca relative to 3H2O were 0.371 +/- 0.056 and 0.492 +/- 0.086 (mean +/- S.E. of mean) res
