Stimation of reference interval of lipid profile in Assamese population     

Madhumita Das  Mauchumi Saikia 《Indian journal of clinical biochemistry : IJCB》2009,24(2):190-193

12hrs fasting samples of 1485 apparently healthy, Assamese population in the age group of 20–80 yrs., mostly from the urban area of Assam were tested for serum lipid profile that includes total cholesterol, triacylglycerol, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C) and very low density lipoprotein cholesterol (VLDL-C) over a period of three years. The values (median and range in mg/dl) obtained were 170 (93–263); 110 (40–256); 40 (23–73); 103 (40–173) and 22 (8–51) respectively. After grouping these subjects according to the age and sex no significant difference were observed between most of the groups. Median and upper range of total cholesterol, HDL-C and LDL-C were found to be higher in women than in men in all the age groups. But triacylglycerol and VLDL-C concentrations were observed to be higher in the men than women except in age group of 61–70 yrs. It can be suggested that lipid values obtained in this study can be used as the reference value, based on which clinical correlation can be made.  相似文献   

Divergences in learning and memory among wild zebrafish: Do sex and body size play a role?     

Tamal Roy  Anuradha Bhat 《Learning & behavior》2018,46(2):124-133

Given its diverse ecological distribution, zebrafish has great potential for investigations on the effect of habitat characteristics on cognition. Studies were conducted on four wild-caught zebrafish populations to understand the role of native habitat, sex, and body size in determining learning through a novel task associated with a food reward. The habitat variables, namely, the relative abundances of zebrafish and predatory fish and the substrate and vegetation diversity, were quantified during fish sampling. Fish were subjected to a novel task to find a food reward in a maze over successive training trials followed by a test for memory. Performances of subjects were based on time taken to find the food reward and number of mistakes made during trials, and tests for memory. The experiments revealed significant differences in learning rates and memory across populations. Males made significantly fewer mistakes than females only within two populations. No relationship between performance and body size was observed. The differences in learning and memory among wild zebrafish could be due to differences in predation, complexity, and stability of the native habitats. These findings suggest the possible role of multiple interacting factors in determining learning and memory among populations and point to a need for incorporating effects of several factors in future studies.  相似文献   

Effect of Tulsi (<Emphasis Type="Italic">Ocimum sanctum</Emphasis> Linn.) Supplementation on Metabolic Parameters and Liver Enzymes in Young Overweight and Obese Subjects     

Swayamjeet Satapathy  Namrata Das  Debapriya Bandyopadhyay  Sushil Chandra Mahapatra  Dip Sundar Sahu  Mruthyumjayarao Meda 《Indian journal of clinical biochemistry : IJCB》2017,32(3):357-363

Ocimum sanctum Linn. (also known as Tulsi) is a sacred Indian plant, the beneficial role of which, in obesity and diabetes is described traditionally. This is a randomized, parallel group, open label pilot study to investigate the effect of O. sanctum on metabolic and biochemical parameters in thirty overweight/obese subjects, divided into two groups A and B. Group A (n = 16) received one 250 mg capsule of Tulsi (O. sanctum) extract twice daily in empty stomach for 8 weeks and group B (n = 14) received no intervention. Statistically significant improvements in the values of serum triglycerides (p = 0.019); low density lipoprotein (p = 0.001); high density lipoprotein (p = 0.001); very low density lipoprotein (p = 0.019); Body Mass Index, BMI (p = 0.005); plasma insulin (p = 0.021) and insulin resistance (p = 0.049) were observed after 8 weeks in the O. sanctum intervention group. The improvement in HDL-C in the intervention group when compared to the control group was also statistically significant (p = 0.037). There was no significant alteration of the liver enzymes SGOT and SGPT in both the intervention (p = 0.141; p = 0.074) and control arms (p = 0.102; p = 0.055) respectively. These observations clearly indicate the beneficial effects of O. sanctum on various biochemical parameters in young overweight/obese subjects.  相似文献   

Effects of chronic ethanol exposure on renal function tests and oxidative stress in kidney     

Subir Kumar Das  Sowmya Varadhan  L. Dhanya  Sukhes Mukherjee  D. M. Vasudevan 《Indian journal of clinical biochemistry : IJCB》2008,23(4):341-344

After administration, ethanol and its metabolites go through the kidneys and are excreted into urine. The kidney seems to be the only vital organ generally spared in chronic alcoholics. Therefore, we investigated the multiple effects of chronic ethanol exposure on renal function tests and on oxidative stress related parameters in the kidney. Chronic ethanol (1.6 g ethanol/ kg body weight/ day) exposure did not show any significant change in relative weight (g/ 100g body weight) of kidneys, serum calcium level or glutathione s-transferase activity. However, urea and creatinine concentration in serum, and TBARS level in kidney elevated significantly, while reduced glutathione content and activities of glutathione peroxidase, glutathione reductase and superoxide dismutase diminished significantly after 12 weeks of ethanol exposure. Catalase activity showed increased activity after 4 weeks of ethanol exposure and decreased activity after 12 weeks of ethanol exposure. Genesis of renal ultrastructural abnormalities after 12 weeks of ethanol exposure may be important for the development of functional disturbances. This study revealed that chronic ethanol exposure for longer duration is associated with deleterious effects in the kidney.  相似文献

The teacher efficacy for inclusive practices (TEIP) scale: dimensionality and factor structure     

Mi‐Hwa Park  Dimiter M. Dimitrov  Ajay Das  Margaret Gichuru 《Journal of Research in Special Educational Needs》2016,16(1):2-12

The Teacher Efficacy for Inclusive Practices (TEIP) scale is designed to measure teacher‐self efficacy to teach in inclusive classrooms. The original study identified three scale factors: efficacy in using inclusive instruction (EII), efficacy in collaboration (EC), and efficacy in managing behavior (EMB) (Sharma et al., 2012). The purpose of our study was to examine the TEIP scale for dimensionality and to cross‐validate its factor structure for pre‐service teachers in the context of early childhood education. A bifactor model fit to the data revealed that the TEIP scale is essentially unidimensional, that is, there is one dominant latent factor and the originally found three scale factors (EII, EC, and EMB) represent specific aspects of the general factor of teacher self‐efficacy to teach in inclusive classrooms. Along with providing validation evidence, these findings have important implications for the scoring on the TEIP scale using classical test analysis or unidimensional item response theory models.  相似文献   

The mystery behind flowering     

Siraj?DattaEmail author  Malay?Das 《Resonance》2002,7(12):42-47

The concepts of photoperiodic induction, hormonal regulation and florigens used to form the basis of our knowledge of flowering. Consequent upon the advancement of technology, our present day understanding suggests that a number of events like switching on of a cascade of genes, and the subsequent activation of MADS box genes, result in the activation of the the genes responsible for flowering in angiosperms.  相似文献   

Assessment of quality of higher education in hostile environment: an analysis on provincialised colleges under Assam University Silchar     

Prasun Das  Srabanti Mukherjee  Suprabir Dutta Roy 《Quality in Higher Education》2016,22(1):36-48

Historically low average pass rate has been a perennial challenge for the universities and provincialised colleges in the North-Eastern states of India (Assam, Meghalaya, Mizoram, Nagaland, Tripura, Manipur and Arunachal Pradesh). Pass rate refers to the proportion of students promoted from one semester to the next and also the proportion of students who pass the final examination to be a graduate. The paper attempts to trace the key parameters for quality improvement for higher education in the region and subsequently augment the pass rate. An inductive content analysis was conducted based on focus group interviews at various levels at Assam University, Silchar and its affiliated provincialised colleges. The four broad categories thus identified (academic, administrative, socio-economic and placement issues) were subjected to Pareto 80-20 principle to identify the issues that are to be given priority for evolving the system. The study would help the administrators to measure the quality of higher education system in a hostile environment characterised by adverse topography, political disturbances, skewed distribution of income, widespread poverty and lack of literacy.  相似文献   

An easy, rapid and cost-effective method of microtitration     

Mala Das Sharma  Ch. Dhanamma 《Resonance》2005,10(10):78-83

An economical and less time consuming microtitration method is presented. The method has been applied to two types of titration, viz., neutralization and complexometric. The results obtained by the new method are comparable to those obtained by conventional method using burette and pipette. It is proposed that this method can be implemented in high school and undergraduate classes as the quantities of chemicals consumed are far less and the experiment can be completed within the given laboratory period.  相似文献
