The Antarctic continent on the planet Earth is full of environmental extremes. It is considered as natural stress model. Therefore, the present study examined the effect of harsh environment on the certain salivary markers of 28th Indian Antarctic expeditioners. Thirty healthy men and women (median age 36 year; range 22–61 year) participated in this study. Parameters measured were salivary IgA (SIgA), IgM (SIgM), TGF-β and cortisol level at three different time points: (I) before leaving India on 26th October 2008 for base line level; (II) after 1 month on-board journey on 31st January 2009 in Southern Ocean and (III) after 1 month staying at Maitri, Antarctica on 3rd March 2009. Our observation indicated that Ship borne journey and Antarctic environment increased the SIgA levels while that of SIgM level was not altered on-board but decreased by staying for 1 month at Antarctica. No significant alteration was found in the TGF-β and cortisol level at any point of time. The present study concluded that ship borne journey and Antarctic environment may induce the SIgA level while SIgM level decreased in environmental extremes of Antarctica. 相似文献

选用课堂互动双编码分析系统(MFIAS),运用矩阵分析和曲线分析等方式,从课堂氛围、教师提问倾向、课堂结构、教学风格等方面对"一师一优课"中的某一堂高中数学优质课教学视频进行分析.研究表明:该数学课堂气氛融洽,师生互动频繁;教学方式多样化,教师充分尊重学生的主体地位,主要采用"小步走"的教学模式.这启示我们:为了提升师生课堂互动行为效率,教师要加强信息技术与数学课程的融合,营造融洽的课堂氛围,构建课堂教学共同体;让问题驱动学习,提高学生的问题解决能力;合理安排课堂小结,梳理数学知识脉络. 相似文献

Serum antioxidant status and peroxidative stress was estimated in 30 pregnant women, their newborn infants and 25 non-pregnant
women. Serum Ascorbic acid, α-tocopherol, retinol & β-carotene levels were found to be significantly reduced and peroxidative
stress was significantly higher in mothers as compared to matched non-pregnant women. Newborn had significantly higher levels
of ascorbic acid as compared to their mother but had significantly lower levels of lipid soluble vitamins. The peroxidative
stress in newborn was found to be significantly less as compared to their mothers. A positive correlation of ascorbic acid
and α-tocopherol levels between mother and newborn reflects that their status in mother does influence the newborn status. 相似文献
