Lipid peroxidation products and antioxidants were estimated in either blood, serum or erythrocytes of 25 cases of early and 25 of advanced senile (50–60 years) cataract and 30 persons of age matched healthy controls. Serum lipid peroxidation products (as malondialdehyde) were significantly higher in patients with early senile (0.25±0.05 μm/dl, P<0.05) and advanced senile cataract (0.29±0.05 μm/dl, P<0.001) as compared to healthy controls (0.22±0.07 μm/dl). Erythrocyte superoxide dismutase levels were lower in patients with early senile (730±60.5 units/gm Hb) and significantly lower in advanced senile (712±50.2 units/gm Hb, P<0.05) cataract than those in healthy controls (767±59.5 units/gm Hb). Serum α-tocopherol was significantly lower (P<0.05) in only advanced senile cataract (0.69±0.08 mg/dl) but not in early senile cataract (0.75±0.08 mg/dl) when compared with healthy controls (0.75±0.09 mg/dl). There was no significant difference in the erythrocyte concentration of reduced glutathione and serum levels of total proteins, β-carotene, vitamin A, ascorbic acid, calcium, magnesium and zinc. 相似文献

Regulation of intracellular cholesterol homeostasis exists under balance between intracellular biosynthesis and uptake from extracellular origin by cell surface transport proteins. Expected role of cholesterol on either tumor suppressor gene and/or DNA synthesis has been aimed in the present study to explore intracellular cholesterol homeostasis in CLL subjects. Higher expressions of p53R2 (p53 dependent subunit of ribonucleotide reductase) and p53 were found in lymphocytes of chronic human lymphocytic leukemia as comparison to their normal counterparts. Inverse relation was found with p53 independent R2 subunit (in human hRRM2) of ribonucleotide reductase, which was found to be decreased from its control group. More expression of peripheral type benzodiazepine receptor, a cholesterol transporter, was noticed in isolated nuclear fraction with simultaneous increase of cholesterol concentration in cytoplasmic and nuclear compartments. A parallel increase of cholesterol in cell nucleus with increased p53R2 expression shows priority of the involvement of cholesterol in the process of cell replication. 相似文献

Abstract The author conducted a study with early childhood educators in New Delhi to understand the teachers’ perceptions of the relationship between their preparation and practice within a theory‐practice framework. The research problem emanated from the observations and experiences of the author, indicating an existing three‐way tension between the design of current Indian teacher education programs, the dominant discourse of early childhood education, and the underlying values of Indian philosophy that defined the construct of the teacher and child in Indian society. 相似文献

In this paper, we reflect upon how dialogs and debates in a non-governmental organization (NGO) – CARE India in the context of a girls’ education project shaped staff members’ understandings of gender justice. As CARE India staff shared their experiences in the field, in the organization, and in domestic spaces during gender training sessions and other forums, their different politics in these spaces shaped how they translated global discourses of gender justice to produce fluid, contested, and contextual understandings. While these dialogs included the voices of diverse social actors in identifying the capabilities needed for gender justice in education, they were often reframed by local NGO actors. 相似文献

Fibromyalgia syndrome (FMS) patients have disturbed sleep patterns which may lead to altered circadian rhythm in serum cortisol secretion. The aim of this study was to assess circadian changes, if any, in serum cortisol levels in female patients with FMS. Cortisol levels were estimated every 6 h during 24 h period; in 40 female patients satisfying ACR criteria for FMS (Age 36.4 ± 9.9), and 40 healthy females without FMS (Age 33.8 ± 11.1). A significant difference in the night time serum cortisol level was observed among the patients and control groups (patients, 12.9 ± 9.7 controls 5.8 ± 3.0; p < 0.01). However, no significant difference was found in serum cortisol levels in patients and control groups in the morning (patients, 28.4 ± 13.2 controls, 27.6 ± 14.5; p > 0.05), afternoon (patients, 14.4 ± 5.6 controls, 14.0 ± 6.6; p > 0.05) and evening hours (patients, 10.9 ± 5.8 controls, 8.9 ± 3.6; p > 0.05). It could be concluded that there is an abnormality in circadian secretion of cortisol in female FMS patients. 相似文献

The increasing incidence of obesity, leading to metabolic complications is now recognized as a major public-health problem.
Insulin resistance is a central abnormality of the metabolic syndrome, or syndrome X, originally hypothesized by Reaven Insulin
resistance is more strongly linked to intra abdominal fat than to fat in other depots. Adipose tissue secretes numerous factors
(adipokines) known to markedly influence lipid and glucose/insulin metabolism, oxidative stress, and cardiovascular integrity.
Some of these adipokines have been shown to directly or indirectly affect insulin sensitivity through modulation of insulin
signaling and the molecules involved in glucose and lipid metabolism. A pilot study was conducted with 80 healthy subjects
who were non diabetic, non hypertensive and having no family history of hypertension, the aim was to evaluate the correlation
of adiponectin and leptin levels with obesity and insulin resistance markers in healthy north Indian adult population. Serum
leptin, adiponectin and insulin was estimated by sandwich ELISA method. In our study, Leptin correlated significantly with
BMI (P value of 0.0000), WC (P value = 0.007), and HC (P value = 0.000). leptin showed significant positive correlation with fasting insulin (P value 0.002), post prandial insulin (P value = 0.000) and HOMA-IR (P value = 0.002). Adiponectin showed significant positive correlation with triglycerides (P value = 0.038), strong negative correlation with HDL-cholesterol (P value = 0.017). Serum concentrations of leptin are associated with central body fat distribution. Insulin resistance and
adiponectin is associated with dyslipidemia and these all disorders may ultimately lead to metabolic syndrome. 相似文献

In this article, we review research on the economics and sociology of education to assess the relationships between family and community variables and children’s educational outcomes in South Asia. At the family level, we examine the variables of family socioeconomic status (SES), parental education, family structure, and religion and caste. At the community level, we assess the limited research on the relationships between economic, cultural, and social characteristics and children’s educational outcomes. The literature presents several consistent relationships between the roles of family and community characteristics in determining educational outcomes and reveals several possibilities for further research. 相似文献
