ABSTRACT
Objective@#To understand the sedentary behavior level of children and adolescents with intellectual disabilities in Jinan City, and to provide a reference basis for developing health behavior intervention strategies.@*Methods@#By used the method of cluster random sampling,the Children s Leisure Activities Study Survey was used to investigate the sedentary behavior level of 285 children and adolescents with intellectual disabilities aged 6-18 years from 7 special education schools in Jinan City.@*Results@#The sedentary behavior time during the whole week among children and adolescents with intellectual disabilities in Jinan City was 394.46 min/d, including 378.00 min/d on weekdays(Monday to Friday) and 388.80 min/d on weekends (Saturday and Sunday), the difference was statistically significant ( Z =-2.19, P <0.05). 80.4%(229) of children and adolescents with intellectual disabilities had sedentary behavior time of more than 2 h/d. The sedentary behavior time per day during the whole week among children and adolescents with intellectual disabilities was negatively correlated with the amount of time spent in moderate vigorous physical activity among them ( r =-0.16, P <0.05).@*Conclusion@#Excessive sedentary behavior has become a growing public health concern among children and adolescents with intellectual disabilities,which warrants targeted healthy behavior intervention.
ABSTRACT
Angiographically silent cystoid macular edema (CME) is a rare complication from nab-paclitaxel. Here we report a 45-year-old woman with breast cancer who developed CME after several months of treatment with albumin-bound paclitaxel (nab-paclitaxel). Her visual acuity did not improve significantly with the cessation of nab-paclitaxel and intravitreal ranibizumab treatment. Then, brinzolamide eye drops were prescribed. One month later, her vision improved, with the macular edema significantly subsided. Finally, we reviewed other cases of CME induced by nab-paclitaxel that have been reported in the literature and discussed the underlying pathogenesis of nab-paclitaxel-induced CME.
ABSTRACT
Numerous transcription factors (TFs) in ascomycete fungi play crucial roles in cellular processes; however, how most of them function is poorly understood. Here, we identified and characterized a novel TF, CxrC (POX01387), acting downstream of the key TF CxrA, which is essential for plant-biomass-degrading-enzyme (PBDE) production in Penicillium oxalicum. Deletion of cxrC in P. oxalicum significantly affected the production of PBDEs, as well as mycelial growth and conidiospore production. CxrA directly repressed the expression of cxrC after about 12 hr following switch to Avicel culture. CxrC bound the promoters of major PBDE genes and genes involved in conidiospore development. CxrC was found to bind the TSSGTYR core sequence (S: C and G; Y: T and C; R: G and A) of the important cellulase genes cbh1 and eg1. Both N- and C-terminal peptides of CxrC and the CxrC phosphorylation were found to mediate its homodimerization. The conserved motif LPSVRSLLTP (65-74) in CxrC was found to be required for regulating cellulase production. This study reveals novel mechanisms of TF-mediated regulation of the expression of PBDE genes and genes involved in cellular processes in an ascomycete fungus.
