Increased levels of oxidized proteins with aging have been considered a cardiovascular risk factor. However, it is unclear whether oxidized albumin, which is the most abundant serum protein, induces endothelial damage. The results of this study indicated that with aging processes, the levels of oxidized proteins as well as endothelial microparticles release increased, a novel marker of endothel...

The application of a multi-frequency laser source for the use in matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOFMS) is described. An elliptically polarized beam of a Nd:YAG laser emitting at 355 nm (200 mJ) is focused into a Raman shifter, filled with high pressure hydrogen. As a result, numerous Raman lasers (including vibrational and rotational Raman em...

The type and loading level of oxygen-containing functional groups on graphene oxide (GO) nanosheets significantly affect the size alignment nanochannels formed between GO separation performance laminar membranes. Here, we demonstrate how double-oxidation leads to higher surface charge nanosheets, formation highly stable water-based solution, more-ordered deposition GOs polyethersulfone membrane...

Nordin Fredrikson G, Hedblad B, Berglund G, Nilsson J (Malmö University Hospital, Lund University; and Biomedical Laboratory Science, Malmö University, Sweden). Plasma oxidized LDL: a predictor for acute myocardial infarction? J Intern Med 2003; 253: 425–429. Objectives. Oxidized LDL has been attributed a key role in the development of atherosclerosis. Previous studies have demonstrated increas...

Oxidative stress plays an important role in the pathophysiology of preeclampsia. In a case-control study of 99 women with preeclampsia and 99 controls, we assessed maternal plasma oxidized low-density lipoprotein (oxidized LDL) in relation to preeclampsia risk. Logistic regression procedures were used to derive odds ratios (OR) and 95 % confidence intervals (CI). Plasma oxidized LDL was determi...

Background: Hyperbilirubinemia is one of the most important complications encountered in neonatal units. It has been proposed that phototherapy yields oxidative stress. Therefore, this study was undertaken to survey the levels of antioxidant and oxidative stress in the serum of neonates before and after phototherapy. Methods: This study was performed on thirty-five healthy, late preterm (>35 w...

hantzsch 1, 4-dihydropyridines (1,4-dhps) can be oxidized to the corresponding pyridine derivatives by thallium triacetate in high yields.
