treated sea water is the most significant source of water and surfactant floods. the various chemicals employed in treatment plants should be compatible with surfactant systems. based on surface tension experiments, the activity of these chemicals is examined over a wide range of concentrations in different solutions, including distillated water, sea water by using three types of surfactant mix...

glucose-6-phosphate dehydrogenase (g6pd) deficient subjects are vulnerable to oxidative stress. quercetin, a flavonoids, has been employed as a potent oxygen-free radical scavenger in order to assess the protective effects of quercetin against h2o2-induced oxidative damage in g6pd-deficient and normal human erythrocytes. erythrocytes of g6pd-deficient (n = 10) and normal (n = 10) subjects were ...

P latelets play a critical role in thrombotic diseases such as myocardial infarction or ischemic stroke. Beyond their role in thrombosis, platelets are the major trigger in boosting atherosclerosis.2 In patients with hypercholesterolemia, platelets are hyperreactive, indicating that circulating lipoproteins in blood influence platelet properties. Lipidlowering drugs result in a reduction of pla...

We study the kinetics of a diffusion-controlled reaction in which perfect traps (scavengers) diffuse and consume randomly distributed particles. We find that the number of particles remaining after time t decays as exp(-actd”), for spatial dimensions d 1 2 , and as exp(-act) for d 3 2 , where U is a constant, and c is the trap concentration. These predictions are supported by Monte Carlo data i...

We have previously demonstrated that the acetyl low density lipoprotein (LDL), or scavenger, receptor is expressed by rabbit smooth muscle cells (SMCs) and fibroblasts. Moreover, receptor activity in rabbit fibroblasts was regulated over a wide range by preincubating the cells with secretion products from human platelets or with phorbol esters. The current studies were undertaken to examine the...

Background: Several lines of evidence suggest that oxidized LDL (Ox-LDL) scavenger receptors play a crucial role in the genesis and progression of diabetic atherosclerosis. This study aimed to elucidate the effect of vitamin D3 on gene expression of lectin-like oxidized LDL receptor-1 (LOX-1), scavenger receptor-A (SR-A), Cluster of Differentiation 36 (CD36), and Cluster of Differentiation 68 (...

For adsorbents used in water remediation, the long-standing contradictions between selectivity and multiple adsorbability, and affinity and recyclability, have led to difficulties in applications towards environmental crises. In article number 1500289, Q. Yuan and co-workers create a versatile scavenger that cleverly avoids such contradictions by integrating the advantages of multiple functiona...

An oxygen scavenging film based on a catalytic system with palladium (CSP) was combined modified atmosphere (MA) packaging to extend the mould free shelf life (MFSL) of bakery products. Par-baked buns, toast bread and gluten-free inoculated Aspergillus niger spores were packed in normal (NA) under MA (with 2 vol.-% O ) or without CSP. Mould growth detected after 2–3 days all products NA as well...

This study explores the effects of initial Cr(VI) concentration, wavelength, hole-scavenger (absence and presence salicylic acid), oxygen conditions (aeration by air, nitrogen gas, mechanical stir only) on photocatalytic reduction hexavalent chromium over titanium dioxide photocatalyst chromic species distribution after photocatalysis. The experimental results show existence strong interactions...

This work analyzes the role of natural groundwater, as well effect HCO3−, Ca2+, Mg2+, K+, SO42- and Cl− concentrations, upon photocatalytic nitrate reduction using ilmenite catalyst oxalic acid hole scavenger. The removal selectivity towards N2 are significantly limited compared to previous experiments ultrapure water matrix. Calcium (Ca2+), bicarbonate (HCO3−) pH claimed major controlling fact...
