Prior studies have investigated sperm retrieval rates in men with non obstructive azoospermia(NOA)secondary to specific etiologies,yet most cases of NOA are *** compared sperm retrieval rates and testicular histopathology in idiopathic NOA(iNOA)and nonidiopathic NOA(niNOA).We performed a retrospective review of men with NOA who underwent microdissection testicular sperm extraction(microTESE)between 2000 and *** with no history of malignancy or cryptorchidism and negative genetic evaluation were considered *** regression determined the association between idiopathic etiology and primary outcomes of sperm retrieval and active spermatogenesis on *** 224 men,86(38.4%)were idiopathic,75(33.5%)were nonidiopathic,and 63(28.1%)did not undergo genetic *** age and serum testosterone were higher among iNOA or no testing versus *** follicle-stimulating hormone(FSH)was lower among iNOA or no testing versus niNOA.A higher proportion of iNOA or no testing versus niNOA had a clinical *** retrieval rates were similar between iNOA,niNOA,and no testing(41.8%vs 48.0%vs 55.6%,respectively;P=0.255).Active spermatogenesis was seen in a higher proportion of iNOA or no testing versus niNOA(31.4%and 27.0%vs 16.0%,P=0.073).On multivariable analysis,iNOA was not associated with sperm retrieval or spermatogenesis(P=0.430 and P=0.078,respectively).Rates of sperm retrieval and spermatogenesis on testis pathology were similar in men with iNOA and *** data will be useful to clinicians in preoperative counseling for men with NOA and negative genetic evaluation.

Synthesis of N-arylquinolone derivatives bearing 2-thiophenoxyquinolines and their antimicrobial evaluation

引用

Chinese Chemical Letters 2014年第7期25卷 1073-1076页

作者： mehul B.Kanani Manish P.patel Department of Chemistry Sardar Patel UniversityVallabh Vidyanagar 388120India

A new series of 2-thiophenoxyquinolines based trifluoromethyl substituted N-aryl quinolone derivatives 8a-f and 9a-f have been synthesized via a one-pot multicomponent reaction. In vitro antimicrobial activity of the synthesized compounds was investigated against a representative panel of pathogenic strains. Compounds 8c, 9c and 9e exhibited comparable antimicrobial activity to first line drugs.
