PURPOSE To assess the validity of frozen section examination (FSE) on testis nodules. MATERIALS AND METHODS A series of 86 preselected patients with testicular nodules were recruited in this study. Nodules smaller than 2 cm had been surgically removed and biopsies of the margins performed. Larger nodules were just biopsied. Orchiectomy was the treatment of choice for malignant lesions and str...
Galacomannan was isolated from Trigonella foenum graceum Linn Family: Leguminosae (TF) seeds. The objective was to study the anabolic and androgenic activity of galactomannan in immature castrated male rats and also on testicular histology in non-castrated immature rats. The rats (55± 5 g) were castrated. The rats were treated with either vehicle, testosterone (10 mg/kg s.c. bi weekly) or galac...
Most of the earlier investigations on the gonads of teleosts have been concerned with the lineage of germ-cells (Nussbaum, 1880; Eigenmann, 1891; Dodds, '10; Sink, '12; and Bachmann, '14). The structural development of the radialtype testis, as well as the history of the germ-cells in Cottus, was described by Hann ( '27). Essenberg ( '23) traced the development of the acinus-type testis in Xiph...
The objective of this study was to evaluate the reproductive risk associated with exposure of adult male Fisher-344 rats to inhaled benzo(a)pyrene (BaP). Rats were assigned randomly to a treatment or control group. Treatment consisted of sub-chronic exposure of rats via inhalation to 75microgBaP/m(3), 4h daily for 60 days, while control animals were unexposed (UNC). Blood samples were collected...
Cancer testis antigens (CTAs) are of clinical interest as biomarkers and present valuable targets for immunotherapy. To comprehensively characterize the CTA landscape of non-small-cell lung cancer (NSCLC), we compared RNAseq data from 199 NSCLC tissues to the normal transcriptome of 142 samples from 32 different normal organs. Of 232 CTAs currently annotated in the Caner Testis Database (CTdata...
The present study was performed on pregnant female mice, by intrapertionealy injection of Camcolit (antipsychotic drug) at a daily dose of 25 mg /kg B.W. for 31 day. The treatment started 10 days after conception, during gestation and through postnatal weaning of the male offspring on neonatal development of the mouse t il l they reach 21 days, to describe the indirect effect of low therapeutic...
BACKGROUND The dmrt1 and sox9 genes have a well conserved function related to testis formation in vertebrates, and the group of fish presents a great diversity of species and reproductive mechanisms. The lambari fish (Astyanax altiparanae) is an important Neotropical species, where studies on molecular level of sex determination and gonad maturation are scarce. METHODS Here, we employed molec...
BACKGROUND The aim of this study was to investigate whether there is a need for diagnostic biopsies in men with obstructive azoospermia (OA). METHODS Sixty-three adult men with OA due to vasectomy, bilateral inflammation or bilateral aplasia of the vas deferens were included in the study. We determined testicular volume, sexual hormone levels and testicular histologies of right and left teste...
The spiny lobster Panulirus homarus, distributed along the Southeast and Southwest coasts of India, is an important commercial species having mariculture potential. Despite its importance, the structural and ultrastructure features of male gonads from this species have received scarce attention. Hence this study was aimed to describe the male reproductive tract of the species, using standard hi...
Trigonella foenum (TF) has long been used in the traditional Indian systems of medicine for the treatment of various ailments. The objective was to study the anabolic and androgenic activity of the furostanol glycosides fraction of Trigonella foenum-graecum (Fenu-FG) in immature castrated male Wistar rats. It was also aimed to investigate the effect of Fenu-FG on testicular histology in non-cas...
