| El objetivo de esta actualización fue revisar los hallazgos concernientes a la posible utilidad clínica de nuevos biomarcadores de estrés oxidativo-nitrosativo, especialmente aquellos derivados del metabolismo lipídico, como herramientas a implementar en el diagnóstico diferencial, la prognosis, el riesgo o la evaluación de estrategias terapéuticas, en enfermedades crónicas de tipo degenerativo. Se analizó la información disponible sobre el uso de marcadores emergentes en casos de infertilidad masculina por varicocele, pacientes con neurodegeneración debida a mal de Alzheimer, de Parkinson, o demencias de origen vascular, enfermos con cáncer de pulmón, próstata o mama, diabéticos tipo 2 y personas expuestas a agroquímicos en forma profesional. Como... |

| A bovine, Bos indicus, with bilateral varicocele diagnosticed by palpation and ultrasound observation was observed during 24 months measuring scrotal circumference, semen quality, testosterone concentrations comparing with seasonal variation and other animals of the same species. The abnormal morphology of major defects and minor defects didn't change between the bull and the other animals, however, the total defects were higher during the summer in the bull with varicocele (49,9%±6,9) when compared with the other bulls (27,9%±2,9). The animal showed higher percentage of major defects during the summer, comparing with the other seasons of the year. For the animal with varicocele testosterone levels were significantly higher during the different season's of... |

| One of the proposed mechanism by which varicocele induces its damage is excessive release of nitric oxide (NO). Several studies have shown the role of NO in poor sperm quality in infertile patients with varicocele. Scientific studies have demonstrated the beneficial effects of curcumin on the sperm parameters. Curcumin as an atoxic antioxidant can reduce production of NO. The aim of this study was to determine the effect of curcumin on NO levels and investigate if curcumin can improve sperm parameters in varicocelized male rats. Thirty male Wistar rats were randomly divided into 5 groups (V1 and V2 (varicocele), T (treatment), Sh (sham) and C was control). In groups V1, V2, T and Sh, the left renal vein was partially ligated to induce varicocele. In groups... |

| In this study, we aim to examine effects of an experimentally induced unilateral varicose ovarian vein on the activities of anti-oxidant enzymes in an adult rat ovary. In this experimental study, a total of 30 adult female Wistar albino rats were divided into three groups. 10 rats in group 1 as the varicocele group, 10 rats in group 2 as the control group and 10 rats in group 3 as the sham group, that underwent a sham operation and. Anti-oxidant assays were assessed via specific assay kits. Statistical analysis was performed using the one way ANOVA and Tukey's tests were used for post hoc multiple comparisons, P<0.05 was considered statistically significant. The effects of the unilateral varicosity was more evident on the left side when compared to the... |

| Varicoceles are abnormal tortuosity and dilatation of the veins of the pampiniform plexus that drain the testis.The pathophysiology of testicular damage in varicocele has not been completely understood. However there is an increasing body of evidence pointing towards the role of reactive oxygen species and oxidative stress in the pathogenesis of varicocele related subfertility. In the present study we examined the role of proanthocynidin-rich ethanol extract of grapefruit seed as an antioxidant in protecting the testis against damage in experimental varicocele. Three groups of rats were constructed as the first group had intact rats; experimental bilateral varicoceles were established by complete ligation of the left and right main spermatic veins in the... |

| The duplication of gonadal vessels is mainly found on the left side, with less numbers of bilateral cases. The objective of this work is describing a case of bilateral duplication of gonadal veins, where two veins were draining to inferior vena cava, being that the closest vein of kidney medial margin had a thickness of 2.68mm and was distant 64.41 mm of the organ. The second vessel had a thickness of 1.43mm and was distant 73.76mm. Two veins follow to left renal vein, being that the first vessel had a thickness of 2.7mm and was distant 21.8mm of the kidney medial margin; the other had a thickness of 1.64mm and was distant 35.13mm of the organ. The presence of variations on the local of drainage of gonadal vessels has clinical importance for comprehension... |
