In the dose-dependent experiment, the mice were treated with whole-body X-ray irradiation at different doses (25, 50, 75, 100 or 200 mGy) and sacrificed 12 h later. In the time-dependent experiment, the mice were exposed to 75 mGy X-ray irradiation and killed at different time points (3, 6, 12, 18 or 24 h). Testicular cells were harvested for experiments. H202 and NO concentrations, and Ca2+-ATPase activity were detected by biochemical assays, the calcium ion concentration ([Ca2+]i) by flow cytometry using fluo-3 probe, and GRP78 mRNA and protein expressions by quantitative real-time RT-PCR (qRT-PCR) and Western blotting, respectively. The mRNA expressions of S-XBP1, JNK, caspase-12 and CHOP were measured by qRT-PCR, and the protein expressions of IREla, S-XBP1, p-PERK, p-elF2a, ATF6 p50, p-JNK, pro-caspase-12, cleaved caspase-12 and CHOP by Western blot- ting. The results showed that the concentrations of H202 and NO, the mR_NA expressions of GRP78, S-XBP1, JNK, caspase-12 and CHOP, and the protein expressions of GRP78, S-XBP1, IREla, p-PERK, p-elF2a, ATF6 p50, p-JNK, pro-caspase-12, cleaved caspase-12 and CHOP were significantly increased in a time- and dose-dependent manner after LDR. But the [Ca2]i and Ca2-ATPase activities were sig nificantly decreased in a time and dose-dependent manner. It was concluded that the ERS, regulated by IRE 1, PERK and ATF6 pathways, is involved in the apoptosis of testicular cells in LDR mice, which is associated with ERS-apoptotic signaling molecules of JNK, caspase-12 and CHOP.展开更多

The aim of our study was to report the diagnostic and evolutionary aspects of testicular cancer cases treated in our center. Patients and Methods: A retrospective study conducted over a 15-year period involving 12 patients treated for testicular cancer at the University Hospital of Brazzaville. Results: The median age was 31 years (range 11 to 49 years), with a median consultation delay of 10.6 months (range 3 to 27 months). Scrotal mass was the most common reason for consultation. Cancer was bilateral in two patients. Two patients were admitted with metastatic disease. Histopathological examination favored germ cell tumors in 7 cases, two cases of non-Hodgkin’s malignant lymphoma, and one case of epididymo-testicular adenocarcinoma. Adjuvant chemotherapy resulted in complete remission in patients with germ cell tumors. However, neoadjuvant chemotherapy was not effective in patients admitted with advanced-stage disease. Conclusion: Testicular cancer is a rare condition that is curable in the majority of cases, but its management is often complicated in our setting due to delayed diagnosis caused by taboos surrounding genital organ pathologies.展开更多

Thus far,...The molecular basis for enhanced chemosensitivity of testicular germ cell tumors (GCT) has been an area of great interest, as it could potentially give us therapeutic leads in other resistant malignancies. Thus far, however, the increased sensitivity of C&T has been variously attributed to multiple factors -- an inability to detoxify cisplatin, a lack of export pumps, an inability to repair the DNA damage, an intact apoptotic cascade and lack of p53 mutation; but a unifying underlying etiology leading to the aforementioned processes and having a translational implication has so far been elusive. Herein, we offer evidence to support a potential significant role for the previously demonstrated low hypoxia inducible factor-la (HIF-la) expression in mediating the general exquisite chemosensitivity of testicular GCT, through the aforementioned processes. This molecular mechanism based hypothesis could have a significant translational implication in platinum refractory GCT as well as other platinum resistant malignancies.展开更多

Methods: The study included 16 Turkish idiopathic infertile men with azoospermia or oligozoospermia who underwent testicular biopsy to examine mast cells containing tryptase. In all patients, a complete medical history, clinical examination, semen analysis and serum hormone assay were carried out. The biopsy specimens were immunohistochemically stained with antihuman tryptase for mast cells. The number of total mast cells per seminiferous tubule was calculated and recorded as mast cell index. The patients were divided into two groups according to their mast cell index: the higher (≥1, n=9) and the lower (<1, n=7) index groups. Fexofenadine was administered orally at a dose of 180 mg/day for 4 to 9 months. Pre-and post-treatment semen parameters, including total motile sperm counts (TMC) were recorded and compared. Spontaneous pregnancies after the treatment were registered. Results: There was no statistically significant difference in TMC between the pre-treatment and post-treatment values in patients with higher and lower mast cell index (P≥0.05). In both groups, nobody had a significant response to the treatment and there was no spontaneous pregnancy after the treatment. Conclusion: Although testicular dysfunction is closely associated with increased number of testicular mast cells, fexofenadine, a mast cell blocker, appears not having any benefit in the treatment of Turkish infertile men with a significant increase in testicular mast cells.

The authors report the case of a young Senegalese 21, who has consulted for an occlusive syndrome evolving for 48 hours that prompted his hospitalization. Note that the patient has consulted several times to persistent inguinal scrotal pain, a big right purse with chronic analgesic requirements and anti-inflammatory. Occlusive before this table, abdominal pelvic CT was performed and highlighted the presence of lung metastases, a large pelvic lymph node casting bridging the inter vesico-rectal space and responsible for extrinsic compression of the small intestine, lymph node inter casting aorto-cellar and latero aortic liver and multiple secondary locations. Faced with this bundle of arguments, clinical and laboratory, metastatic testicular tumor was raised and measured tumor markers. A right orchiectomy by inguinal was made with histology: A non-seminomatous germ cell tumor stage III. After orchiectomy germinal markers were still high and there was the problem of persistent occlusive syndrome despite resuscitation. A chemotherapy regimen was initiated with 4 cycles of chemotherapy according to the protocol BEP (bleomycin, etoposide, cisplatin). A significant regression of occlusive syndrome with a decline in clinical symptoms was noted. The revaluation at 3 months, 6 months and 1 year were highlighted: A normal clinical examination associated with a persistent correction rate of germline markers and lack of active lesion at thoraco-abdominopelvic CT.展开更多

We retrospectively evaluated 89 patients with a mean age of 26.5 years. After orchiectomy, 37 patients were treated with surveillance, 34 underwent RPLND and 18 were managed with chemotherapy. The overall survival rate, the recurrence-free survival rate and the risk factors were evaluated. The median follow-up length was 92 months (range: 6-149 months). Thirteen of the 89 patients (14.6%) had relapses, and one died by the evaluation date. The overall survival rate was 98.9%. The cumulative 4-year recurrence-free rates were 80.2%, 92.0% and 100% for the surveillance, RPLND and chemotherapy groups, respectively. The disease-free period tended to be briefer in patients with a history of cryptorchidism and those with stage Is. Therefore, surveillance, RPLND and adjuvant chemotherapy might be reliable strategies in compliant patients with CSI NSGCT. Surveillance should be recommended for patients with the lowest recurrence rate, especially those without lymphovascular invasion. This study might aid the establishment of a standard therapy for CSI NSGCT in China.展开更多

The patients were referred to the Urology Department in Salah Alden Hospital. Methods: The present study was carried out from May 2017 until June 2018 and the number of the patients group was 60. The patients aged between 20 to 50 years. 20 of them were selected and subjected to histopathological examinations by taking biopsies from their testes. Results: The sertoli-cell-only syndrome (SCOS) was the most common positive histopathological finding comprising 35% of the cases. This was followed by testicular atrophy with 30%, while maturation arrest was 20%. The percentage of hypospermatogenesis was 10% and normal spermatogenesis was 5%. Conclusion: Among the 20 specimens examined, the sertoli-cell-only syndrome (SCOS) was the most common positive histopathological finding. The semen analysis and testicular biopsy provide valuable information about the etiology and the fertility potential of an individual.展开更多
