Children\'s Deafness
This is an article about children's deafness, it's ethiology, diagnosis, treatment, and educational treatment. Here I have given a brief account about the deafness itself and it's individual and social complications, also it's impression on the psychological well baing of the child. Then I have discussed, rather in detail, the ethiology of .children's deafness and I have given some statistic...
متن کاملCloning of the kanamycin resistance gene from a kanamycin-producing Streptomyces species.
A kanamycin-producing strain, Streptomyces kanamyceticus ISP5500, is resistant to kanamycin. A kanamycin resistance determinant was cloned from S. kanamyceticus into Streptomyces lividans 1326, using the plasmid vector pIJ702. The resulting plasmid, pMCP5, could also transform Streptomyces lavendulae S985 and Streptomyces parvulus 2283 to kanamycin resistance. Transformants carrying pMCP5 were ...
متن کاملModulation of kanamycin B and kanamycin A biosynthesis in Streptomyces kanamyceticus via metabolic engineering
Both kanamycin A and kanamycin B, antibiotic components produced by Streptomyces kanamyceticus, have medical value. Two different pathways for kanamycin biosynthesis have been reported by two research groups. In this study, to obtain an optimal kanamycin A-producing strain and a kanamycin B-high-yield strain, we first examined the native kanamycin biosynthetic pathway in vivo. Based on the prop...
متن کاملSudden deafness
The author explains the clinical presentation, pathophysiology, diagnostic work-up, and management of sudden deafness. "Sudden" deafness is defined as sensorineural hearing loss of 30 decibels or more in at least 3 contiguous frequencies occurring over less than 3 days. The pathophysiology of sudden deafness is poorly understood. Various theories have been proposed, including those attributing ...
متن کاملFeline deafness.
Cats have among the best hearing of all mammals in that they are extremely sensitive to a broad range of frequencies. The ear is a highly complex structure that is delicately balanced in terms of its biochemistry, types of receptors, ion channels, mechanical properties, and cellular organization. Sensorineural deafness is caused by "flawed" genes that are inherited from one or both parents. Hea...
