Dietary restriction (DR) and its advantages     

M. N. Astagimath  Shrinivas B. Rao 《Indian journal of clinical biochemistry : IJCB》2004,19(1):1-5

Dietary restriction (DR) also called dietary control or calorie restriction is reported to have many advantages with regard to human health. It leads to suppression of obesity, mitigates free radicals and increases available antioxidants which are accounted for extending the life span of individuals. DR is also reported to induce synthesis of heat shock proteins in animals as a control mechanism against stress. Further, it is known to play a significant role in decreasing toxicity and lethality due to a variety of toxic chemicals and drugs by stimulating tissue repair damaged by the toxicants leading to restoration of intact organ and its functions. Moreover, extensive work done on animals indicate DR has an important role in suppressing certain types of cancer. In this review an effort is made to highlight the various advantages of DR from the point of human health perspective.  相似文献   

Standardization of a dilution method for cyclosporin (C2) estimation in renal transplant patients     

G. Kusumanjali  Chinnapu G. Reddy  A. S. Kanagasabapathy  Pragna Rao 《Indian journal of clinical biochemistry : IJCB》2005,20(2):146-149

Accurate monitoring of blood cyclosporin C2 levels is vital to prevent over immunosuppression and acute renal toxicity in patients who receive organ transplant. The matrix used to dilute patients’ C2 samples prior to the assay affected the final measured values. Hence there was a need to develop a method of dilution that would accurately estimate C2 levels when cyclosporin levels were beyond the calibration range of the method employed. Whole blood, cyclosporin free hemolysate and cell and protein free supernatant obtained after pretreatment of normal blood were used to dilute patients’ C2 samples. C2 was measured in 188 patients using the supernatant method of dilution. C2 was correlated with Co and dose of cyclosporin received by the patient. The use of cell and protein free supernatant obtained after pretreatment of normal blood as a C2 diluent detected higher levels of C2 in the sample. Measured C2 correlated significantly with Co and the cyclosporin dose received by the patient. The uniformly aqueous cell and protein free supernatant ensures uniform dilution of the patients’ C2 sample and measures higher cyclosporin levels.  相似文献

Confronting poverty and educational inequalities: Madrasas as a strategy for contesting dominant literacy in rural Bangladesh     

Nitya Rao  Munshi Israil Hossain 《International Journal of Educational Development》2011

In a context of globalisation and the rapid expansion of low-paid ‘global’ jobs, formal schooling is no longer perceived as contributing to the acquisition of skills that are appropriate or even relevant to active engagement with the new opportunities. Based on empirical material from a village in Bangladesh, this paper explores the role of madrasa education in challenging the dominant paradigm of learning embedded in formal secular schooling. Despite charges of low quality and traditionalism, local narratives reveal how madrasa learning is used to negotiate and transform inequalities, both in material and social terms. Madrasa education is cheaper, and addresses issues of poverty, but the narratives also emphasise learning the Arabic language, seen to facilitate male overseas migration to the Gulf countries, a channel for upward social and economic mobility. In a context of global competition that supports individualism, a focus on character and morality as represented through an Islamic identity, alongside communitarian values, is seen as important for maintaining a degree of social cohesion and is hence socially valued. Reading and reciting the Quran are also viewed as essential traits for a woman, enabling her to appropriately socialise her children in the absence of her migrant husband. One finds here a simultaneous process of contestation and resistance, seeking successful occupational trajectories and social recognition for men, while at the same time contributing to the reproduction of gendered inequalities.  相似文献   

Where are all the typical numbers — 2     

B. V. Rao 《Resonance》2011,16(11):1029-1038

In this two-part article, we are trying to discover patterns in the decimal digits of numbers between zero and one. In Part I we started showing that each digit occurs with frequency 1/10. We reduced the problem with the help of Borel-Cantelli Lemma and Markov inequality to show certain sums of integrals are finite. In this concluding part we bring in an essentially new ingredient and conclude the proof.  相似文献

Myeloperoxidase in Chronic Kidney Disease     

Madhusudhana Rao A  Anand U  Anand CV 《Indian journal of clinical biochemistry : IJCB》2011,26(1):28-31

Numerous lines of evidence implicate a role of myeloperoxidase (MPO) in the pathogenesis of cardiovascular disease (CVD). It is a well accepted fact that patients with chronic kidney disease (CKD) are at an increased risk for CVD. MPO is a pro-oxidant enzyme which could be involved in the increased susceptibility of these patients to CVD. Hence, the levels of plasma MPO was determined in healthy controls as well as in patients with CKD [stratified with the level of their kidney failure as CKD stages II–V (end stage renal disease)]. Plasma MPO was assayed by a spectrophotometric method. Serum urea and creatinine were estimated on a clinical chemistry analyzer using standard laboratory procedures. The mean plasma MPO levels were significantly lower with advancing stages of renal failure (P < 0.001). There was a positive correlation between MPO and GFR (r = +0.89, P < 0.001) and a negative correlation with urea (r = −0.85, P < 0.001) and creatinine (r = −0.82, P < 0.001). While an inverse association was observed between plasma MPO and urea in CKD patients, such an association was not observed in control subjects (P = 0.43). In conclusion, the decline in plasma MPO levels may be due to the inhibitory effect of uraemic toxins on the enzyme.  相似文献
