background and aim: tinnitus is perception of sound in absence of external source. reaction time is the time between sensory stimuli and a behavior. alternation of auditory reaction time has been shown in the literature in patients with tinnitus. this study has investigated the auditory reaction time in quiet and noise to different frequencies. methods: fifteen subjects with chronic tinnitus pa...

An efficient synthesis of polyhydroquinoline derivatives is achieved via Hantzsch condensation reaction between aldehydes, dimedone, ethyl acetoacetate and ammonium acetate in the presence of catalytic amount of SFHS in ethanol. This method gives remarkable advantages such as shorter reaction time, simple workup procedure and good to excellent yields. Furthermore the catalyst can be recovered c...
