Advanced age is associated with an accumulation of free radical damage, which leads to physiological and clinical modifications.
Age related changes resulting from free radical reactions include increasing levels of lipid peroxides, alterations in enzyme
activities and greater osmotic fragility. The present study was conducted to estimate the level of lipid peroxidation product-Malondialdehyde
and antioxidants Catalase and Glutathione in elderly people. An increase in lipid peroxidation and decrease in antioxidants
was observed in normal elderly people. Highly significant increase in MDA and decrease in antioxidants was observed in elderly
people when complicated with diabetes and hypertension. Supplementation of antioxidants may prevent further oxidative injury
in elderly people. 相似文献

The roles of habit and web site quality in e-commerce 总被引：1，自引：0，他引：1
Previous research has primarily examined consumers’ perceived usefulness of web sites and trust in the web retailer as two major predictors of web site use and e-commerce adoption. While the consumers’ repeated behavior in the past (i.e., habit) may contribute to continuance behavior, it has not been investigated. This article includes habit as a primary construct along with perceived usefulness and trust to predict and explain consumers’ continued behavior of using a B2C web site. Additionally, included are several web quality measures as antecedents to trust and perceived usefulness. The research model is evaluated using structural equation modeling. Results show that consumers’ behavioral intentions to continue using a B2C web site are determined by all three key drivers: perceived usefulness, trust, and habit. Furthermore, not all dimensions of web quality have a significant effect on perceived usefulness and trust. 相似文献

Both (a) in-school factors such as over-focus on academic performance, absence of uniform, and corporal punishment, and (b) out-of school factors such as caring for ailing parents, child labour, etc., hinder participation of orphan and vulnerable children (OVC) in Free Primary Education (FPE) system in Nyanza Province, Kenya. In this context Concern Worldwide Kenya undertook an appreciative capacity building approach and appropriately positioned District Education Office (DEO) of the Ministry of Education and local civil society organisations (CSOs) to address in-school and out-of-school factors, respectively, to ensure quality education for OVC. The outcome of the programme is promising and has demonstrated the need for greater cooperation between CSOs and the government to develop creative strategies in overcoming the causes of marginalisation within the contexts of the growing AIDS pandemic and poverty in Kenya. 相似文献

The present study reveals the effect of Musa paradisiaca stem juice on blood glucose level (BGL) of normal & diabetic rats.
The dose of 500 mg/kg bodyweight produces a significant rise of 28.3% in blood glucose level after 6h of oral administration
in normal rats. Whereas, in sub diabetic rats the same dose produces a rise of 16.4% in blood glucose levels within 1h during
glucose tolerance test (GTT) and a rise of 16% after 4 h in fasting blood glucose levels of severe diabetic cases. These results
were unexpected and important to report as other species of Musa like Musa sapientum has been reported for its hypoglycemic
effect. 相似文献

Cloud computing has become the buzzword in the industry today. Though, it is not an entirely new concept but in today's digital age, it has become ubiquitous due to the proliferation of Internet, broadband, mobile devices, better bandwidth and mobility requirements for end-users (be it consumers, SMEs or enterprises). In this paper, the focus is on the perceived inclination of micro and small businesses (SMEs or SMBs) toward cloud computing and the benefits reaped by them. This paper presents five factors influencing the cloud usage by this business community, whose needs and business requirements are very different from large enterprises. Firstly, ease of use and convenience is the biggest favorable factor followed by security and privacy and then comes the cost reduction. The fourth factor reliability is ignored as SMEs do not consider cloud as reliable. Lastly but not the least, SMEs do not want to use cloud for sharing and collaboration and prefer their old conventional methods for sharing and collaborating with their stakeholders. 相似文献

The aim of the study was to ascertain the role of ethanolic extract of Cynodon dactylon against hepatic complications in streptozotocin
(STZ) induced type 2 diabetic models. Effect of the pre identified most effective dose of 500 mg/kg body weight was studied
on hepatic injury caused by chemically induced diabetes by 55 mg/kg body weight i.p. injection of STZ in male Wistar rats.
The dose of 500mg/kg body weight given once daily for 14 days reduced the levels of serum glutamate oxaloacetate transaminase,
serum glutamate pyruvate transaminase, alkaline phosphatase, creatinine and urine sugar significantly (P<0.05) with increase
in total protein, haemoglobin and body weight was increased. High LD50 validates its high margin of safety. 相似文献

The present study defines the systematic evaluation and the role of minerals in glycemic potential of aqueous extract of Withania
coagulans fruits in order to develop an effective and safe alternative treatment for diabetes mellitus. Laser Induced Breakdown
Spectroscopy was used for glycemic element detection. The study is based on the results of lowering in blood glucose levels
of normal, sub, mild and severely diabetic rats assessed during fasting blood glucose, glucose tolerance test and post prandial
glucose studies. The dose of 1000mg/ kg was identified as the most effective dose, which reduces the Fasting Blood Glucose
level maximum by 33.2% at 4h in normal rats during fasting blood glucose studies. Glucose tolerance test studies of normal,
sub and mild diabetic rats showed the maximum reduction of 15.7, 28.9 and 37.8% at 3h respectively. Long-term study in case
of severely diabetic rats showed reduction of 52.9 and 54.1% in Fasting Blood Glucose and Post Prandial Glucose levels respectively
after 30 days of treatment. The present study, besides confirming hypoglycemic and antidiabetic activities of aqueous extract
of W. coagulans, helps in identifying the role of trace minerals like Mg & Ca responsible for antidiabetic potential of this
potent indigenous shrub. 相似文献

The present study deals with the evaluation of glycemic profile of aqueous extract of Cajanus cajan leaves in streptozotocin induced type 2 diabetic rats. Single oral administration of graded doses of aqueous extract of Cajanus
cajan leaves showed significant increment of 14.3 % in fasting blood glucose levels of normal rats. The sub diabetic and mild diabetic
models have also shown hyperglycemic effect from the same variable doses of the extract. The dose of 1000 mg/kg showed the
maximum rise of 17.1, 71.2 and 50.7 % in Blood glucose levels of normal, sub and mild diabetic rats respectively during glucose
tolerance test. The study of leaves was taken into consideration on the basis of earlier reported hypoglycemic activity of
Cajanus cajan seeds. However the results observed were found just opposite and therefore it may be useful in controlling hypoglycemia,
occasionally caused due to excess of insulin and other hypoglycemic drugs. 相似文献

ABSTRACTThe goal of this paper is to describe and analyze the relationship between ability tracking and student social trust, in the context of low-income students in developing countries. Drawing on the results from a longitudinal study among 1,436 low-income students across 132 schools in rural China, we found a significant lack of interpersonal trust and confidence in public institutions among poor rural young adults. We also found that slow-tracked students have a significantly lower level of social trust, comprised of interpersonal trust and confidence in public institutions, relative to their fast-tracked peers. This disparity might further widen the gap between relatively privileged students who stay in school and less privileged students who drop out of school. These results suggest that making high school accessible to more students may improve social trust among rural low-income young adults. 相似文献

The effect of primary school mergers on academic performance of students in rural China 总被引：1，自引：0，他引：1

We examine the impact of primary school mergers on academic performance of students using a dataset that we collected using a survey designed specifically to examine changes in the academic performance of students before and after their schools were merged. We use difference-in-differences and propensity score matching approaches and demonstrate that overall the primary school merger has not harmed the academic performance of students, as some have claimed. We do find, however, that the timing of mergers matter; when students are older (e.g., the fourth grade) their grades rise after merging. The grades of younger students, however, fall. 相似文献
