1. MENX and MEN4
Multiple endocrine neoplasias are autosomal dominant disorders characterized by the occurrence of tumors in at least two endocrine glands. Two MEN syndromes have long been known and are well characterized: the MEN type 1 (MEN1) and type 2 (MEN2). These syndromes are caused by germline mutations in the MEN1 and RET genes, respectively, and have a different tu

2. Testículo de Astyanax altiparanae Garutti e Britski, 2000. Estudo morfológico, ultraestrutural e imuno-histoquímico. / Testis of Astyanax altiparanae Garutti e Britski, 2000. Ultrastructural and immunohistochemical study.
O teleósteo Astyanax altiparanae, popularmente conhecido como lambari importância econômica e ecológica. Poucos são os trabalhos que visam demonstrar a morfologia dos testículos de brasileiros. O objetivo deste estudo foi classificar e demonstrar as alterações morfológicas do testículo de Astyanax altiparanae ao longo do ciclo gonadal e quantificar

3. Morphology of the alimentary canal of the gecko Hemidactylus mabouia (Moreau de Jonnès, 1818) (Squamata: Gekkonidae) / Morfologia do tubo digestivo da lagartixa Hemidactylus mabouia (Moreau de Jonnès, 1818) (Squamata: Gekkonidae).
Hemidactylus mabouia is the gecko species more thoroughly distributed in Brazil, being common in anthropic atmospheres, what turns easy its use as model for study of the reptiles. Likewise, aiming at to describe morphologically the alimentary canal of H. mabouia, 17 adult specimens were used, being collected fragments of the esophagus, of the oesophagogastri

4. Regulação hormonal da prostata de femeas do gerbilo : avaliação estrutural, citoquimica e imunocitoquimica / Hormonal regulation of the gerbil female propstate: morphology, cytochemistry and immunocytochemistry
The female prostate is a functionally active gland found in several species of mammals, including humans and rodents. In adult female gerbils, the prostate presents a paraurethral location, showing close contact with the wall of urethra in its median and distal portions. This gland is homologue to the ventral prostate of male rodents and it is formed by a cl

5. Expressão do VEGF e vascularização do corpo lúteo em búfalos / Expression of VEGF and vascularization of corpus luteum in buffalos
O corpo lúteo é uma glândula endócrina temporária que regula tanto o ciclo estral quanto a prenhez, apresentando extrema dependência de aporte sanguíneo adequado. O tratamento superovulatório aumenta a concentração sérica de progesterona (P4) e conseqüentemente as taxas de concepção e de prenhez. Esse trabalho objetivou quantificar a vasculariz

6. Reproductive experience influences grooming behavior during pregnancy in rats
The pregnancy-induced increase in self-licking observed in rats is important for mammary gland development and lactation. Reproductive experience has epidemiologial implications such as a decrease in the incidence of mammary gland cancer in women and it also influences various behavioral, neurochemical and endocrine parameters. The aim of the present study w

7. An immunohistochemical study of gastrointestinal endocrine cells in a nectarivorous marsupial, the honey possum (Tarsipes rostratus).
The distribution and relative frequency of occurrence of gastrointestinal endocrine cells exhibiting immunoreactivity to eleven peptides and one amine were examined immunohistochemically in the gastrointestinal mucosa of the adult honey possum which feeds almost exclusively on nectar and pollen. Seven types of endocrine cells, immunoreactive for serotonin, s

8. ABCA1 plays no role in the centripetal movement of cholesterol from peripheral tissues to the liver and intestine in the mouse
This study uses the mouse to explore the role of ABCA1 in the movement of this cholesterol from the peripheral organs to the endocrine glands for hormone synthesis and liver for excretion. The sterol pool in all peripheral organs was constant and equaled 2,218 and 2,269 mg/kg, respectively, in abca1+/+ and abca1−/− mice. Flux of cholesterol from these ti

9. The postnatal development of the alimentary canal in the opossum. II. Stomach.
The postnatal development of the gastric mucosa in the opossum has been traced with the light, transmission and scanning electron microscopes. The formation of fovea and gastric glands occurs simultaneously during the postnatal period. During the first 60 postnatal days the developing gastric glands are composed of undifferentiated cells, parietal cells and

10. The persistence of placental remnants, beyond the normal period of gestation, in rats ovariectomised at day 12 of pregnancy.
The uterus, mammary glands and vaginal epithelium were examined in rats ovariectomised at day 12 of pregnancy and killed between 10 and 16 days later, and in a group of normal post partum rats. All the animals were injected with tritiated thymidine one hour before death. Some placental remnants persisted in all the ovariectomised animals and were associated

11. Exocrine secretion granules contain peptide amidation activity.
Exocrine secretion granules from the rat parotid gland contain a carboxyl-terminal peptide alpha-amidation enzyme resembling closely an enzyme from the pituitary (peptidyl-glycine alpha-amidating monooxygenase) that functions in post-translational processing of secretory polypeptides within neural and endocrine secretion granules. alpha-Amidation is a charac

12. The Corpuscles of Stannius, Calcium-Sensing Receptor, and Stanniocalcin: Responses to Calcimimetics and Physiological Challenges
This study has examined whether the calcium-sensing receptor (CaSR) plays a role in control of stanniocalcin-1 (STC-1), the dominant calcium regulatory hormone of fish, comparable with that demonstrated for CaSR in the mediation of ionized calcium regulation of PTH secretion in mammals. In a previous study, we have cloned flounder STC-1 from the corpuscles o
