BACKGROUND The epidemiology of plasma lipid peroxides, which may play a role in atherogenesis, has not been well defined. AIM To study the relationships of plasma lipid peroxides to cardiovascular risk factors in a random population sample. DESIGN Random, age- and sex-stratified population sample. METHODS We studied 739 men and women aged 25-74 years. Lipid peroxides were assayed by the t...

PURPOSE To investigate whether lipid peroxides play a role in retinal cell death due to ischemia-reperfusion injury, whether recombinant human thioredoxin (rhTRX) treatment reduces production of lipid peroxides of the retina, and whether such treatment reduces the number of cells expressing c-Jun and cyclin D1. METHODS Retinal ischemia was induced in rats by increasing the intraocular pressur...

The precise mechanisms of alopecia, a pathophysiological disorder with negative psychological implications, are unknown. Androgen and hereditary predisposition are major causes, but the condition is also affected by stress, an irregular diet and high levels of sebum secretion. We focused on oxidative stress and analyzed the effect of the lipid peroxides on hair follicles. Our first observation ...

The present review describes the current status of synthetic five and six-membered cyclic peroxides such as 1,2-dioxolanes, 1,2,4-trioxolanes (ozonides), 1,2-dioxanes, 1,2-dioxenes, 1,2,4-trioxanes, and 1,2,4,5-tetraoxanes. The literature from 2000 onwards is surveyed to provide an update on synthesis of cyclic peroxides. The indicated period of time is, on the whole, characterized by the devel...

A cross-sectional study was done to see the possible association of plasma lipid peroxides in the elderly with age and other factors. Plasma lipid peroxides is a product of free radical reactions which according to the latest theory of aging is the cause of aging process. Lipid peroxides were also found high in coronary heart disease. Four hundred forty relatively healthy elderly, age 55-85 yea...

The present study was conducted in patients with cervix and ovarian carcinoma to evaluate the status of oxidative stress biomarkers as protein carbonyl and lipid hydro peroxides. Biomarkers of oxidative stress were measured as protein carbonyl (PC) and total lipid hydro peroxides (LOOH). Newly diagnosed women with carcinoma (n=100; 30-65 years of age) and agematched clinically healthy women (n=...
