Histopathologic analysis confirmed benign

prostatic hyperplasia (BPH) in all patients, and mean specimen weight on pathologic examination was 127 g (range 100-165 g). Mean follow-up duration was 7.2 months with all patients having a minimum of a 4-month follow-up. Significant improvements were noted in the International Prostate Symptom Score (preoperative vs postoperative 18.1 vs 5.3, p < 0.001) and the maximum CAL-101 cost urine flow rate (preoperative vs postoperative 4.3 vs 19.1 mL/min, P < 0.001).

Conclusions: Minimally invasive robot-assisted simple prostatectomy is techincally feasible in patients with large volume (> 100 g) BPH and is associated with significant improvements in obstructive www.selleckchem.com/products/8-bromo-camp.html urinary symptoms. Surgeons with robotic expertise may consider using this approach for treatment of their patients with large volume BPH.”
“The quality of the biodiesel is of most importance for the success in the marketing of this fuel. Among the qualitative parameters there is the kinematic viscosity that can be affected due to the degradation of biofuel. Such degradation occurs on account of the weather changing

and also because of some catalytic agents. Because of that the stability to oxidation was denominated as a factor which relates the resistance level of the product to the different oxidizing agents. The present work aimed to study the oxidative stability of the biodiesel produced of the crambe and the soybean vegetal oil. The techniques of infrared spectroscopy, refractive index and kinematic viscosity were used to monitor the level of oxidation of the biodiesels. The biodiesels were submitted to a thermal stress in an incubator, at 130 degrees C for a final period of 22 h of study, and were contaminated with iron and bronze filings. The viscometric studies showed

that the crambe biodiesel is more stable than the soybean biodiesel at the end of their exposure to the thermal stress, as well as that the addition of 5% and 10% of crambe biodiesel lowers the viscometric alteration https://www.selleckchem.com/products/blebbistatin.html in about 43.9% regarding the pure soybean biodiesel. By observing the index of refraction it was verified that the alteration in the soybean biodiesel contaminated with bronze was enhanced when compared to the pure biodiesel and the biodiesel contaminated with iron. As for the pure crambe biodiesel and the biodiesel contaminated with iron, the alteration in the index of refraction is minimum, it is only significant for the biodiesel contaminated with bronze, but lower, however than the one observed for the soybean/bronze biodiesel.
