The hypocholesterolemic effect of the water extract of the bark ofFicus bengalensis was investigated in 3 groups of rabbits, 5 in each group. Group 1 rabbits served as healthy controls and were fed with groundnut oil 1 ml/kg body wt. (bw) for five weeks. Groups 2 and 3 were made hypercholesterolemic by feeding orally cholesterol suspended in groundnut oil (1 ml/kg bw) at a dose of 100 mg/kg bw/day. Group 2 animals (untreated) continued to get the same amount of cholesterol for another four weeks. Group 3 animals received water extract of the bark (50 mg/kg bw/day) in addition to cholesterol as above. At the end of the 5th week, water extract not only prevented the elevation of serum cholesterol in the treated animals (Group 3) but also brought down its level to 160±14 mg% as compared to untreated animals (Group 2) 290±42 mg%. There was improvement in other parameters of lipid profile namely HDL & LDL+VLDL cholesterol and triacylglycerol.  相似文献   

Plasma vitamin E levels in carcinoma breast

Plasma vitamin E levels were estimated in 75 patients each of carcinoma breast and benign breast diseases. Mean plasma vitamin E concentration was found to be significantly reduced in malignancy compared to the controls as well as the non malignant conditions. The decrease in plasma vitamin E in cancer patients was directly related with the TNM stage of cancer. The levels, however, did not vary significantly with respect to histopathology or after 8 days of surgery.  相似文献   

INDIAN SECONDARY STUDENTS�� VIEWS ABOUT GLOBAL WARMING: BELIEFS ABOUT THE USEFULNESS OF ACTIONS AND WILLINGNESS TO ACT     

Kiran Chhokar  Shweta Dua  Neil Taylor  Edward Boyes  Martin Stanisstreet 《International Journal of Science and Mathematics Education》2011,9(5):1167-1188

A 44-item survey instrument was designed to determine secondary students?? views about how useful various specific actions related to reducing global warming might be, their willingness to undertake these various actions and the extent to which these 2 might be linked. The instrument was administered to students in grades 6??C?10 (n?=?768) from 4 large schools in metropolitan Delhi, India in which the teaching language was English. The findings indicated that this cohort of Indian students exhibited high levels of concern about climate change and strong willingness to act against global warming and in favour of the environment. The findings are tentatively compared with those from 2 similar survey studies conducted in Western contexts (Spain and Australia).  相似文献

Modeling Web-based library service quality   总被引：1，自引：0，他引：1  

K. Kiran  S. DiljitAuthor Vitae 《Library & information science research》2012

Studies of e-service quality have consistently used adaptations of service-quality measurement tools that have been adopted and extended from traditional service-quality frameworks. However, a fresh insight into the investigation of key determinants of Web-based library service quality, with an emphasis on how library customers perceive service quality, has much to offer. Key determinants were identified, and contributed to the development and empirical testing of a proposed conceptual model of service quality that encompasses environment, delivery, and outcome quality. Unlike the disconfirmation approach, the performance-only measure was used. Participants included postgraduates and academic staff from four research intensive universities in Malaysia. Exploratory factor analysis and confirmatory factor analysis using structural equation modeling was carried out in order to develop and validate a measurement model for Web-based service quality, which included three second-order dimensions and eight first-order dimensions. Insights into the conceptualization of Web-based library-service quality as a multidimensional hierarchical construct are provided. The emergence of specific determinants specific to the Web services supports the notion that measurement of electronic-service quality is different from traditional services, though they may share some common factors.  相似文献   

Numerical Magnitude Representations and Individual Differences in Children's Arithmetic Strategy Use   总被引：1，自引：0，他引：1  

Kiran Vanbinst  Pol Ghesquière  Bert De Smedt 《Mind, Brain, and Education》2012,6(3):129-136

Against the background of neuroimaging studies on how the brain processes numbers, there is now converging evidence that numerical magnitude representations are crucial for successful mathematics achievement. One major drawback of this research is that it mainly investigated mathematics performance as measured through general standardized achievement tests. We extended this research by investigating the association between numerical magnitude representations and children's strategy use during single‐digit arithmetic. Our findings reveal that children's symbolic but not nonsymbolic numerical magnitude processing skills are associated with individual differences in arithmetic. Children with better access to magnitude representations from symbolic digits retrieve more facts from their memory and are faster in executing fact retrieval as well as procedural strategies. These associations remain even when intellectual ability, digit naming, and general mathematics achievement are additionally controlled for. All this indicates that particularly the access to numerical meaning from Arabic symbols is key for children's arithmetic strategy development, which suggests that educators and remedial teachers should focus on connecting Arabic symbols to the quantities they represent.  相似文献   

Reflections on working with critical action learning   总被引：1，自引：3，他引：1  

Clare Rigg  Kiran Trehan 《Action Learning: Research and Practice》2004,1(2):149-165

Critical action learning engages participants in a process of drawing from critical perspectives to make connections between their learning and work experiences, to understand and change interpersonal and organisational practices. But what does this mean in practice? How can critical action learning be expedited? What outcomes can critical action learning have for participants, and can the hopes for critical action learning be fulfilled? The intentions of this paper are to contribute reflections of our empirical experience on working with critical action learning in management development.  相似文献   

Children''s Understanding of the Modal Expression of Speaker Certainty and Uncertainty and Its Relation to the Development of a Representational Theory of Mind   总被引：2，自引：0，他引：2  

Chris Moore  Kiran Pure  David Furrow 《Child development》1990,61(3):722-730

2 experiments examined children's understanding of the expression of speaker certainty and uncertainty and its relation to their developing theory of mind. In the first experiment, 80 children between 3 and 6 years of age were presented with a task in which they had to guess the location of an object hidden in 1 of 2 boxes. As clues to location, the children were presented with contrasting pairs of statements by 2 puppets. Different trials contained all of the possible pairwise combinations of either the modal verbs must, might, and could or the modal adjuncts probably, possibly, and maybe. Results showed that while 3-year-olds did not differentiate between any of the modal contrasts presented, 4-year-olds and older children were able to find the hidden object on the basis of what they heard. Performance was best for contrasts involving a highly certain term (either must or probably) paired with a less certain term (might, could, possibly, and maybe). Experiment 2 was designed to determine whether competence with modal terms was related to competence with mental terms in the same task, and whether performance on the certainty task was related to other aspects of the child's understanding of the nature of beliefs. 26 4-year-olds were presented with the certainty task, involving both modal and mental terms, and with tasks assessing their understanding of false beliefs, representational change, and the appearance-reality distinction. Results showed that all of these tasks were intercorrelated, implying that what may develop at 4 years of age may be a general understanding of the representational nature of belief.  相似文献   

Is device-measured vigorous physical activity associated with health-related outcomes in children and adolescents? A systematic review and meta-analysis     

Antonio García-Hermoso  Yasmin Ezzatvar  Robinson Ramírez-Vlez  Jordi Olloquequi  Mikel Izquierdo 《运动与健康科学(英文)》2021,10(3):296

ObjectiveThis study sought to analyze the prospective association between vigorous-intensity physical activity (VPA) and health-related outcomes in children and adolescents.MethodsStudies reporting associations between device-measured VPA and health-related factors in children and adolescents aged 3–18 years were identified through database searches (MEDLINE, EMBASE, and SPORTDiscus). Correlation coefficients were pooled if outcomes were reported by at least 3 studies, using DerSimonian-Laird random effects models.ResultsData from 23 studies including 13,674 participants were pooled using random effects models. Significant associations were found between VPA at baseline and overall adiposity (r = −0.09, 95% confidence interval (95%CI): –0.15 to –0.03; p = 0.002; I² = 89.8%), cardiometabolic risk score (r = –0.13, 95%CI: –0.24 to –0.02, p = 0.020; I² = 69.6%), cardiorespiratory fitness (r = 0.25, 95%CI: 0.15−0.35; p < 0.001; I² = 57.2%), and total body bone mineral density (r = 0.16, 95%CI: 0.06 to 0.25; p = 0.001; I² = 0%).ConclusionVPA seems to be negatively related to adiposity and cardiometabolic risk score and positively related to cardiorespiratory fitness and total body bone mineral density among children and adolescents at follow-up. Therefore, our findings support the need to strengthen physical activity recommendations regarding VPA due to its health benefits in children and adolescents.  相似文献
