BACKGROUND Mutations in OTOF and PJVK genes cause DFNB9 and DFNB59 types of hearing loss, respectively. The patients carrying pathogenic mutations in either of these genes may show the typical phenotype of auditory neuropathy spectrum disorder (ANSD). The aim of the present study was to identify OTOF and PJVK mutations in sporadic ANSD patients. METHODS(More)
Influences of temperature, humidity, and CO2 concentration on the photosynthesis and respiration of three-year-oldBetula platyphylla was investigated. Light compensation point, saturation point and CO2 compensation point were also determined. The results showed that the optimal temperature of photosynthesis and dark respiration was 24 °C and 30 °C,(More)
The content of total sugar sucrose, fructose and protein in the leaves of 3-yr-oldBetula platyphylia was measured after the treatment by three exogenous sugar solutions (sucrose, fructose, glucose) and three high concentrations of CO2 (700, 1 400, 2 100 μL·L−1) for about a month in 1998. The results showed that spraying three exogenous sugar solutions(More)
