1. Picroside II attenuates ischemia/reperfusion testicular injury by alleviating oxidative stress and apoptosis through reducing nitric oxide synthesis
Abstract Purpose: To investigate the effect of Picroside II on testicular ischemia and reperfusion (l/R) injury and the underlying mechanism. Methods: Sprague-Dawley rats were randomly divided into 4 groups: sham operated group (Sham), Sham with Picroside II treatment group (Sham+ Pic II), l/R group (l/R) and l/R with Picroside II treatment group (I/R+ Pic

2. Effects of folic acid administration on testicular ischemia/reperfusion injury in rats
Abstract Purpose: To determine the effect of folic acid (FA) on experimental testicular ischemia/reperfusion (I/R) in rats. Methods: Sixty male Wistar rats were randomly divided into 6 groups. The control group received physiologic saline orally. The sham-operated group received physiologic saline orally then exposed to midline laparotomy without clamping

3. Protective effect of metformin on testicular ischemia/reperfusion injury in rats
ABSTRACT PURPOSE: To investigate the protective effect of metformin on testicular ischemia/reperfusion (I/R) injury in rats. METHODS: Eighteen adult male Wistar rats were randomly divided into three experimental groups (n=6), as follows: Sham, I/R, and Metformin. 1-hour ischemia was induced by the left testicular artery and vein clipping followed by 7 days

4. Annual male reproductive activity and stages of the seminiferous epithelium cycle of the large fruit-eating Artibeus lituratus (Chiroptera: Phyllostomidae)
The large fruit-eating phyllostomid bat, Artibeus lituratus (Olfers, 1818), forearm 69-75 mm, body mass 66-82 g, has a diversified geographic distribution in the Neotropical region. Therefore it is subjected to different climatic conditions that affect its reproduction, leading to different reproductive strategies such as continuous reproduction, seasonal mo

5. Beneficial effect of pentoxifylline into the testis of rats in an experimental model of unilateral hindlimb ischemia/reperfusion injury
ABSTRACT Objective The objective of the present study was to investigate the role of pentoxifylline (PTX) on remote testicular injury caused by unilateral hind limb ischemia/reperfusion of rats.
Materials and Methods Twenty healthy male Wistar rats were allocated randomly into two groups: isc

6. Protective effects of abdominal electroacupuncture on oxidative stress and inflammation due to testis torsion/detorsion in rats
PURPOSE:To evaluate the effects of acupuncture (Ac) and electroacupuncture (EAc) on oxidative stress and inflammation in testis torsion/detorsion (T/D) model in rats.METHODS: Thirty male Wistar rats were randomized into five groups. G1 Group (Sham) served as control. The remaining groups were submitted to spermatic cord torsion (720°) for 3 hours, followed

7. A bradykinin-potentiating peptide (BPP-10c) from Bothrops jararaca induces changes in seminiferous tubules
Background The testis-specific isoform of angiotensin-converting enzyme (tACE) is exclusively expressed in germ cells during spermatogenesis. Although the exact role of tACE in male fertility is unknown, it clearly plays a critical function in spermatogenesis. The dipeptidase domain of tACE is identical to the C-terminal catalytic domain of somatic ACE (sAC

8. Efeitos do inseticida endossulfam sobre a morfologia e a morfometria testicular em morcegos frugívoros Artibeus lituratus (OLFERS, 1818) / Effects of the endosulfan on the testicular morphology and morphometry in fruit bats Artibeus lituratus (OLFERS, 1818)
Large amounts of agricultural chemicals are discharged into the environment in Brazil. These pesticides are often used to destroy or impair the activity of organisms that attack crops. There are some reports in the literature concerning the decline of many wildlife populations as a result of contamination of their habitats by pesticides. One of the putative

9. Ações da epitestosterona através de um mecanismo de membrana em células de Sertoli : implicações no desenvolvimento sexual
Introduction: Epitestosterone is the 17¿-epimer of testosterone. It seems to possess an antiandrogenic activity, as well as a neuroprotective effect. The mechanism of action of epitestosterone has not been elucidated. Objective: The aim of this work is to investigate the non-classical effect of epitestosterone on the membrane of Sertoli cells from testis of

10. Vias de sinalização intracelular envolvidas no efeito proliferativo de relaxina em células de sertoli / Intracelular signaling pathways involved in the proliferative effect of relaxin in rat Sertoli cells
Relaxin is an insulin-related peptide that activates the G-protein coupled receptor RXFP1. Although relaxin plays an important role in female reproduction its physiological role in the male reproductive system is still unclear. We have previously demonstrated that relaxin and RXFP1 are expressed in testis (FILONZI et al., 2007; CARDOSO et al., 2010). Both re

11. Desempenho e espermatogenese de alevinos de tilapia alimentados com farelo ou farinha de semente de algodao.
Este trabalho avaliou o efeito do farelo e da farinha de semente de algodao no ganho de peso e na atividade testicular de alevinos de tilapia-do-nilo (Oreochromis niloticus). Cento e cinqueta alevinos com peso medio inicial de 1,26 g foram mantidos em aquarios de 45 L, com renovacao continua d'agua, e alimentados por 120 dias com dietas isoproteicas (28% PB)

12. Macroscopic and microscopic study in testes and epididymis of great rhea (Rhea americana, Linnaeus - 1758)(Rheidae) / ESTUDO DE MORFOLOGIA MACROSCÓPICA, MICROSCÓPICA TESTICULAR E EPIDIDIMÁRIA EM EMAS (Rhea americana, Linnaeus 1758)(RHEIDAE)
The purpose of this research was studied the macroscopic morphology of rheas testis and epididymis. Were studied testis from 54 rheas, breed in captivity. In commercial slaughter, were collected testis to analyzed macroscopic measurements of testis and epididymis, consisting in length, width, thickness, circumference, volume, parenchyma and testicular capsul
