Chronic kidney disease is becoming a major health problem globally and in India an alarming number of about 8 million people
are suffering from this disease. Patients undergoing hemodialysis have a high prevalence of protein-energy malnutrition and
inflammation. As these two conditions often occur concomitantly in hemodialysis patients, they have been referred together
as ‘malnutrition-inflammation-atherosclerosis syndrome’ to emphasize the important association with atherosclerotic cardiovascular
disease. The three factors related to the pathophysiology in these patients are dialysis related nutrient loss, increased
protein catabolism and hypoalbuminemia. Inflammation in Chronic Kidney disease is the most important factor in the genesis
of several complications in renal disease. Pro-inflammatory cytokines like IL-1 and TNF-alpha play a major role in the onset
of metabolic alterations in Chronic Kidney disease patients. Atherosclerosis is a very frequent complication in uremia due
to the coexistence of hypertension, hyperhomocysteinemia, inflammation, malnutrition and increased oxidative stress, generation
of advanced glycation end products, advanced oxidation protein products, hyperlipidemia and altered structural and functional
ability of HDL. LDL-cholesterol, apolipoprotein (A), apolipoprotein (B), and Lp(a) are also associated with atherosclerosis.
Studies have now provided enormous data to enable the evaluation of the severity of malnutrition-inflammation-atherosclerosis
syndrome as well as effective monitoring of these patients. 相似文献

Oxidants (NADPH oxidase and myeloperoxidase) and antioxidants (GSH,GSH peroxidase, SOD and glucose 6 phosphate dehydrogenase,
that provides NADPH for antioxidants) were assayed in the neutrophils from oral cancer patients, in three stages viz, baseline
samples,15 days after radiation and 30 days following radiation. These samples were obtained from 2 groups of patients. Group
A that received radiation alone and Group B that received radiation and ocimum flavonoids,a radioprotector. The results showed
a significant fall in the SOD levels in the second follow up of group B.Glucose 6 phosphate dehydrogenase showed significant
increase only in the first follow up of patients who received Ocimum flavonoids. Except for these findings all other parameters
remained statistically nonsignificant. 相似文献

The cause-effect relationship for a wide variety of biological processes from molecular to ecosystem levels can be described
by a curvilinear function called the rectangular hyperbola. Although a simple algebraic equation adequately describes this
curve, biological models have generated different equations incorporating biologically meaningful parameters. The Michelis-Menten
equation describing enzyme kinetics, and the Type II functional response of predators to changing prey densities are two such
examples. 相似文献

Large-scale low-cost synthesis methods for potassium ion battery (PIB) anodes with long cycle life and high capacity have remained challenging. Here, inspired by the structure of a biological cell, biomimetic carbon cells (BCCs) were synthesized and used as PIB anodes. The protruding carbon nanotubes across the BCC wall mimicked the ion-transporting channels present in the cell membrane, and enhanced the rate performance of PIBs. In addition, the robust carbon shell of the BCC could protect its overall structure, and the open space inside the BCC could accommodate the volume changes caused by K+ insertion, which greatly improved the stability of PIBs. For the first time, a stable solid electrolyte interphase layer is formed on the surface of amorphous carbon. Collectively, the unique structural characteristics of the BCCs resulted in PIBs that showed a high reversible capacity (302 mAh g−1 at 100 mA g−1 and 248 mAh g−1 at 500 mA g−1), excellent cycle stability (reversible capacity of 226 mAh g−1 after 2100 cycles and a continuous running time of more than 15 months at a current density of 100 mA g−1), and an excellent rate performance (160 mAh g−1 at 1 A g−1). This study represents a new strategy for boosting battery performance, and could pave the way for the next generation of battery-powered applications. 相似文献
