ABSTRACT
The electrochemical preparation of 2-aminothiazoles has been achieved by the reaction of active methylene ketones with thioureas assisted by á´ Ê-alanine using NH4I as a redox mediator. The electrochemical protocol proceeds in an undivided cell equipped with graphite plate electrodes under constant current conditions. Various active methylene ketones, including ß-keto ester, ß-keto amide, ß-keto nitrile, ß-keto sulfone and 1,3-diketones, can be converted to the corresponding 2-aminothiazoles. Mechanistically, the in situ generated α-iodoketone was proposed to be the key active species.

OBJECTIVE: To investigate the hereditary tendency of varicocele. METHODS: We included in this study 112 varicocele patients, 117 direct male relatives of the patients, and 100 healthy men as controls. We compared the incidence of varicocele tween the direct relative group and the control group. RESULTS: The direct male relatives of the varicocele patients had a significantly higher incidence of varicocele than the healthy controls (36.8% vs 17%, P < 0.05). CONCLUSION: The increased incidence of varicocele in the direct male relatives of the patients indicated a hereditary tendency of the disease.

OBJECTIVE: To investigate the relationship of body mass index with cancer detection on prostate biopsy. METHODS: A total of 168 patients undergoing a prostate biopsy were divided into obese and non-obese groups by BMI ≥ 25 or < 25. Then the differences of prostate-specific antigen (PSA) level, prostate volume, prostate cancer detection rate and pathology result between two groups. RESULTS: The obese group had a higher rate of cancer detection than the non-obese group [67.1% (51/76) vs 48.9% (45/92), P < 0.05]. Logistics regression analysis showed that BMI ≥ 25 had a positive correlation with cancer detection on biopsy. CONCLUSION: Body mass index can raise the risk of prostate cancer on biopsy.
