A series of new 2-(phenylthio) benzoylaryl hydrazones were synthesized by acid-catalyzed condensation of hydrazide 3 with corresponding aldehydes. The chemical structures of the compounds were elucidated by FT-IR, 1H-NMR and Mass spectra. All newly synthesized compounds were evaluated for their antimycobacterial activities against Mycobacterium tuberculosis H37Rv using the microplate alamar blu...

background: literature recommends that refractory cases with lumbar disc herniation and appropriate indications are better to be treated surgically, but do all the patients throughout the world consent to the surgery with a same disability and pain threshold? we aim to elucidate the prevalence and severity of disabilities and pain in iranian patients with lumbar disc herniation who have consent...

background tenofovir disoproxil fumarate (tdf) is a new effective treatment option for patients with chronic hepatitis b (chb). objectives to evaluate tdf efficacy in nucleos(t)ide analogues (nas)-naive iranian patients with chb. patients and methods the na-naive patients received tdf for at least six months. the primary endpoint was the proportion of patients achieving a complete virological r...

In previous works a technique for doing single fault diagnosis in linear analog circuits was developed. Under certain conditions, one of them being exact circuit parameters, it was shown that only two measurements taken on two selected circuit nodes, at a single frequency, were needed to detect and diagnose any parametric fault. In this paper, the practical value of the technique is evaluated b...
