Antioxidant therapy in hemodialysis patients

Cardiovascular problem is the major cause of mortality and morbidity in patients under hemodialysis for chronic kidney disease. Increased lipid peroxidation and depletion of chain-breaking antioxidants may be related to increased risk of atherosclerosis. Oxidative stress and acute phase inflammation are now defined to be highly prevalent in the hemodialysis patients, and several lines of evidence point to their contribution in atherosclerosis development. Antioxidants have been used as therapies to decrease oxidative stress and improve risk of cardiovascular diseases (CVD) in hemodialysis patients. However, plants and fruits antioxidants are reliable ones. Probably, because plants antioxidants are a mixture of several substances with antioxidant activity, which each one supports the other one

The Effect of Divergent Selection on 4-wk BW on the Shape of Growth Curve in Japanese Quail

The current study was conducted to investigate the effect of short-term divergent selection on the shape growth curve in different lines of Japanese quail. The Quail lines utilized in this study were two divergently selected for high (HW) and low (LW) 4-wk body weight during 7 generation and also a control line (C). The Richard function parameters were used to describe growth curves of different lines. The weight at hatch was approximately similar among lines (8.08 g, 7.55 g and 8.76 g for HW, LW and C line respectively). The results of current study indicated that the selected lines (HW & LW) were immediately diverged from the C line after hatch. Sexes within each line had no difference in average growth rate, age and body weight at inflection point and adult body weight. However significant differences were found in the growth curve parameters among lines. The results of current study indicated that short term divergent selection for 4-wk BW in Japanese quail can change the growth pattern and the carcass compartments of the selected birds. Therefore to avoid undesirable side effects due to selection in Japanese quails it is recommended to consider the growth pattern changes of the selected birds in the breeding program

A Parametric Type of the Apostol-Bernoulli, Apostol-Euler and Apostol-Genocchi Polynomials

By defining six specific generating functions, we introduce a kind of parametric Apostol-Bernoulli, Apostol-Euler and Apostol-Genocchi polynomials, we study their basic properties in a systematic manner. As an application of the introduced polynomials, we use them in computing some new series of the Taylor type

Polymers and polymer composites for adsorptive removal of dyes in water treatment

The discharge of wastewater containing dyes causes severe problems worldwide, which must be properly treated before entering the environment. Adsorption is believed to be one of the favourable techniques to remove dyes because of its environmental and economic sustainability. This chapter reviewed the recent development of polymers and polymer composites reported as adsorbents for treating dye-contaminated wastewater, including surface modification/functionalization of polymers, polyaniline and its composites, magnetic polymer composites, polymer/clay composites and polymer/by-products or waste composites. The adsorption performance of adsorbents was discussed in correlation with a number of factors, such as the properties of dyes, surface chemistry or structures of adsorbents, as well as operation conditions, e.g. initial dye concentration, solution pH, temperature, and the presence of other salts, etc. In addition, the regeneration and reusability of developed adsorbents were covered
