Hyperhomocysteinemia (HHCY) has been demonstrated to affect cochlear microvasculature as well as cochlear epithelial cells directly, with a resultant alteration of the expression of matrix metalloproteinases (MMPs) and their inhibitors, tissue inhibitors of metalloproteinases (TIMPs). Hence, ascertaining the optimum concentration of MMPs and TIMPs in the cochlea could help to inhibit hearing loss due to HHCY by the administration of appropriate MMP inhibitors, Since infections/inflammations as well as ototoxic antibiotics have a similar mechanism of otic pathology, the cochlear damage they cause could also be similarly prevented.  相似文献

Researchers of the traditional higher education system identify a number of factors affecting admission to a university (barriers to entry) and factors of its successful completion (barriers to exit). Massive open online courses (MOOCs), available to any Internet user, remove barriers to entry because anyone can study there. But do all students have an equal chance of successful completion of the online course? Do the same barriers to exit exist for MOOCs? Binary logistic regression was used to determine the way that factors related to each student's individual features affect the successful completion of online courses. This study was based on administrative data from the Coursera platform across four courses offered by the NRU HSE from February to June 2014. The results of this analysis show that there is a strong correlation between successful completion of online courses and educational experience. The probability of successful completion is higher among men with higher education who have already taken online courses and studied similar disciplines.  相似文献

Failure to master age-appropriate fundamental movement skills (FMS) at a young age can limit motor skill competence affecting health. Assessments often have issues with feasibility and implementation in a field setting. As such, the purpose of this study was to investigate the validity and feasibility of the Athletic Skills Track (AST), in a pre-school setting. For the validation study sixty-five 3–6 year old children (25 boys and 40 girls) from five pre-schools across Adelaide, Australia participated. Correlations and linear regression analysis (adjusted for age and gender) were used to investigate the association between the time to complete the AST and the raw score of the Test of Gross Motor Development 2 (TGMD-2). For the feasibility study pre-school staff completed a semi-structured interview regarding the feasibility of the AST. The AST took less than a minute per child and the TGMD-2 around 20 minutes for two children. There was a strong negative correlation (r = ?0.63, p < 0.01) between the AST scores and the TGMD-2 scores. All five staff reported strengths of the AST to be its short administration time, setup and appropriateness. These results suggest that the AST could be a feasible and valid method of FMS assessment in Australian pre-schools.  相似文献
