Data of pathological features, treatment given and progress on follow-up was studied. Results: Sertoli-Leydig cell tumor LY2157299 research buy of the ovary accounted for 1.3% of malignant ovarian neoplasms. The median age
of the patient was 30 years. The most common mode of presentation was with hormonal-related symptoms (80%) in the form of secondary amenorrhea, irregular menses and features of virilization. Thirteen of the 15 patients underwent surgical staging and all were found to have stage-I disease at the time of diagnosis. Ten patients with intermediate and poorly differentiated tumors received adjuvant bleomycin, etoposide and cisplatin (BEP) chemotherapy. Recurrent disease was detected in two patients (13.3%) during a median follow-up of 63 months, both of whom had poorly differentiated type of tumor. Both these patients underwent optimal debulking surgery followed by postoperative chemotherapy (BEP regimen). There were no disease -elated deaths and all patients were under complete remission at the last follow-up. Conclusion: As most Sertoli-Leydig cell tumors of the ovary are seen in young women and detected while still in the early stages, a favorable outcome can be achieved by conservative surgery. Patients with moderate and poorly differentiated types of tumors benefit from adjuvant chemotherapy. Recurrences tend to occur early and are commonly
seen in patients with poorly differentiated tumors.”
“BACKGROUND: The aim of the present work was the preparation of TiO(2) P-25 working electrodes on Ti substrates (TiO(2)/Ti), their characterization and the study of their photoelectrocatalytic NVP-AUY922 research buy activity towards the inactivation of E. coil XL-1 blue (E. Coil) colonies, used as model pathogenic bacteria, in a novel batch photoelectrochemical reactor.
RESULTS: After annealing of the TiO(2)/Ti specimens at 500 degrees C, the surface morphology and crystal structure
of the TiO(2) film electrodes were examined by scanning electronic microscopy (SEM) and X-ray diffraction (XRD), while from differential capacitance measurements the flat band potential was calculated (V(fb) = -0.54 V versus Ag/AgCl). The results of photoelectrocatalytic (PEC) JQ-EZ-05 concentration experiments concerning the disinfection of E. coil colonies were compared with those of electrochemical (EC) and photocatalytic (PC) inactivation of the pathogen and showed a significant synergy effect in the case of PEC disinfection, leading, at +1.0 V vs Ag/AgCl cell voltage, to a 100% increase of the apparent rate constant, k(o), in comparison with the simple photocatalytic process. Reuse experiments showed that the working electrode retains its effectiveness after, at least, 15 times of reuse.
CONCLUSIONS: The photoelectrocatalytic inactivation of E. coli colonies has been studied under artificial illumination in a novel photoelectrocatalytic reactor.
