Are beta tubulin mutations rare in human ovarian carcinoma?
This result suggests that mutations within exon four of human beta tubulin are rare in newly-diagnosed and recurrent paclitaxel resistant human ovarian cancer.
The main hypothesis that students sleep on average considerably less than the recommended 9 h during weekdays was confirmed. Bedtimes changed throughout the week with the latest on Friday and Saturday nights and the least sleep around midweek. There were no significant group differences regarding school type and environment (rural vs. urban). Interestingly, the majority reported only little daytime sleepiness and no impaired performance. Results regarding the consequences of chronic sleep deprivation in the literature are inconclusive. The impact on physiological parameters, especially metabolic functions, requires further investigations.
