1. Metabolic and Testicular Effects of the Long-Term Administration of Different High-Fat Diets in Adult Rats
ABSTRACT Purpose: To evaluate the effects of different high-fat diets on body mass, carbohydrate metabolism and testicular morphology in rats seven months old.
Materials and Methods: Male Wistar rats were divided into four groups: SC (standard chow), HF-S (high fat diet rich in saturated fatt

2. Radio frequency electromagnetic radiation (RF-EMR) from GSM (0.9/1.8GHz) mobile phones induces oxidative stress and reduces sperm motility in rats
INTRODUCTION: Mobile phones have become indispensable in the daily lives of men and women around the globe. As cell phone use has become more widespread, concerns have mounted regarding the potentially harmful effects of RF-EMR from these devices. OBJECTIVE: The present study was designed to evaluate the effects of RF-EMR from mobile phones on free radical m

3. Esteróides gonadais e metabolismo lipídico ao longo do ciclo reprodutivo de Arapaima gigas (SCHINZ, 1822) em ambiente natural / Gonad steroids and lipid metabolism along the reproductive cycle of Arapaima gigas (SCHINZ, 1822) in natural environmet
The aim of the present study was to investigate the possible physiological alterations related with reproduction in males and females of Arapaima gigas (pirarucu) in their natural environment. Pirarucu is an obligatory aerial respiration species belonging to a very ancient group of teleosts and inhabits Amazonian river. The main goals of this study were to d

4. Estudo experimental das alterações agudas na glicemia e concentrações testiculares de ATP e glicose induzidas por torção unilateral, in vivo / In vivo acute changes in ATP and glucose concentrations in the rat testicles following unilateral torsion: experimental study
A torção do cordão espermático é a emergência geniturinária mais comum na idade pediátrica. Foram estudadas as alterações metabólicas agudas nas concentrações testiculares de ATP e glicose após uma hora de isquemia induzida por torção do cordão espermático. Sessenta ratos wistar machos pré-púberes, foram distribuídos em 2 grupos de 30 an

6. A transferrinlike (hemiferrin) mRNA is expressed in the germ cells of rat testis.
In the testis, germ cells which are separated from the serum by the blood-testis barrier rely primarily on the Sertoli cell to obtain nutrients. For example, transferrin synthesized by the Sertoli cell is important in delivering iron from the serum to the developing germ cells. Because of its role in the testis, Sertoli cell transferrin protein and mRNA have

7. CD36 mRNA and Protein Expression Levels Are Significantly Increased in the Heart and Testis of apoE Deficient Mice in Comparison to Wild Type (C57BL/6)
CD36, an 88kd-adhesion molecule, plays a major role as a scavenging receptor implicated in cellular lipid metabolism. Secretory mammary epithelium, microvasculature endothelium, adipocytes, smooth muscle cells, and platelets express CD36. In addition, CD36 expression is significantly enhanced in macrophages differentiating into foam cells. The effect of path

8. The testis-specific high-mobility-group protein, a phosphorylation-dependent DNA-packaging factor of elongating and condensing spermatids.
Mammalian spermiogenesis is characterized by a striking restructuring of the spermatid chromatin caused by the replacement of nucleohistones with transition proteins and their subsequent replacement with nucleoprotamines. The onset of nuclear elongation and chromatin condensation in spermatids is accompanied by a general decrease in the transcriptional activ

9. Persistent testicular delta5-isomerase-3beta-hydroxysteroid dehydrogenase (delta5-3beta-HSD) deficiency in the delta5-3beta-HSD form of congenital adrenal hyperplasia.
A partial testicular defect in testosterone secretion has been documented in a pubertal male with a congenital adrenal hyperplasia due to hereditary deficiency of the delta5-isomerase-3beta-hydroxysteroid dehydrogenase enzyme complex (delta5-3beta-HSD). Diagnosis of the enzymatic defect is based on the clinical picture of ambiguous genitalia and salt-losing

10. Reduced Fertility in Male Mice Deficient in the Zinc Metallopeptidase NL1
Members of the M13 family of zinc metalloendopeptidases have been shown to play critical roles in the metabolism of various neuropeptides and peptide hormones, and they have been identified as important therapeutic targets. Recently, a mouse NL1 protein, a novel member of the family, was identified and shown to be expressed mainly in the testis as a secreted

11. Quantitation and intracellular localization of the 85K heat shock protein by using monoclonal and polyclonal antibodies.
Two monoclonal antibodies have been produced against the human 85,000-molecular-weight heat shock protein (hsp85). One of these, 16F1, cross-reacts with the murine homolog and is shown by peptide map immunoblots to be directed against an epitope different from that recognized by the other monoclonal antibody, 9D2. Both monoclonal antibodies recognize only a

12. Immunohistochemical studies on the localisation and ontogeny of heart fatty acid binding protein in the rat.
The localisation and ontogenic expression of heart fatty acid binding protein (H-FABP) were immunochemically examined in the entire body of the rat. In muscles, H-FABP immunoreactivity was observed not only in cardiac muscle cells but also in red skeletal muscles, where gold particles indicating the immunoreaction sites are distributed evenly in the sarcopla
