OBJECTIVES/HYPOTHESIS Quantitative analysis of endoscopic high-speed video recordings of vocal fold vibrations has been growing in importance in recent years. The videos have mainly been analyzed using subjective evaluation, but this is examiner dependent, and the results show inadequate interobserver agreement. The aims of this study were therefore to identify appropriate objective parameters ...

The purpose of this study was to evaluate quantitatively the parameters of the video laryngostroboscopy (VLS) and determine correlations between the VLS parameters and acoustic vocal function parameters. Digital VLS recordings, acoustic voice assessment, calculation of dysphonia severity index (DSI) and registration of voice range profile (VRP) were performed for 206 individuals: 50 healthy and...

following experimental inoculation of 3-week-old turkeys with different titres (106, 104, 103, 102 and 101 egg infectious dose (eid50)) of a/ostrich/italy/984/2000 h7n1 highly pathogenic avian influenza virus (hpaiv), the selected tissues and organs were examined for pathological changes. tissue samples from different organs that obtained from dead and sacrificed birds were fixed in 10% neutral...

we studied the hepatotoxic effects of a deltamethrin containing formulation (decis®) on developing em-bryo of gallus domesticus. fertilized eggs were immersed in three different concentrations of deltamethrin (12.5, 25 and 50 mg/l) for 60 min at 37 ˚c prior to incubation (ed 0) and on the 4th day of incubation (ed 4) and incubated till embryonic day (ed) 16. exposure to 50 mg/l of deltamethrin ...

In this paper a method to analyze pathological speech signal using wavelet transform is suggested. Pathological speech signal is commercially available pathological voice database and analyzed by the suggested method. Normal speech signal is also from the same database and analyzed as well. Then the results are compared to find the differences between normal and pathological speech. Three level...
