An instrument for measuring visual reaction time (VRT) was constructed and later tested on 18 control volunteers. It was established in these subjects that the mean VRT did not vary by more than 6% over a period of 5 days. The equipment was then employed to measure changes in VRT following carotid angiography under general anaesthesia in a series of 48 patients. Of these, 22 patients had no dem...

A structure-guided drug design approach was used to optimize a novel series of aminobenzimidazoles that inhibit the essential ATPase activities of bacterial DNA gyrase and topoisomerase IV and that show potent activities against a variety of bacterial pathogens. Two such compounds, VRT-125853 and VRT-752586, were characterized for their target specificities and preferences in bacteria. In metab...

When the voice register transition (VRT) occurs, vocal-folds motion becomes unstable and the voice pitch jumps abruptly. In this article, we examine the relationship between the fundamental frequency f0 and the first-formant frequency F1 in VRT to reveal the influence of the source–filter interaction (SFI) on VRT. Five Japanese male speakers produced rising glissandos with vowels /a/ and /i/. T...

Auditory reaction time (ART) and visual reaction time (VRT ) between males & females during shift duty in hospital employees have been compared. ART and VRT were studied in 286 hospital employees (141 males and 145 females) during day and night shift duty in the age group of 20 to 60 years. Subjects were presented with two auditory stimuli, i.e. high pitch and low pitch sound and two visual sti...

Variable-rate applications of the nematicide aldicarb were compared to producer standard rates in eight field tests over 3 years. Test areas (308 to 1,015 m long) were divided into eight or five blocks. Each block contained two plots with a variable-rate treatment (VRT) of aldicarb and a producer standard treatment (PST) of aldicarb. Each VRT plot was divided into three subunits and intensively...

UNLABELLED The first two years of life are critical for the acquisition and development of hearing and speaking skills. AIM This prospective study aims to verify the performance of infants with cleft lip and palate (CLP) with and without risk factors for hearing (RFH) in the verbal recognition test (VRT). MATERIAL AND METHOD The parents of 100 infants (9 to 18 months of age) with CLP were i...

Visual and auditory reaction time (VRT, ART) was studied in 83 healthy male subjects of 30-40 years of age who had never practiced yogasanas before. These subjects were divided into two groups viz. Group A whose VRT and ART was determined after 1 hr. yogasanas and Group B whose ART and VRT was determined after 6 weeks yogasanas training programme. VRT and ART showed a significant reduction in G...

background chronic vestibular dysfunction is a frustrating problem in the elderly and can have a tremendous impact on their life, but only a few studies are available. vestibular rehabilitation therapy (vrt) is an important therapeutic option for the neuro-otologist in treating patients with significant balance deficits. objectives the purpose of this study was to assess the effect of vestibula...
