malondialdehyde (mda) is widely used as a biomarker for assessing oxidative stress in biomedical fields. lipid peroxidation is a chain phenomenon resulting in the formation of various active compounds that result in cellular damage. biomonitoring of mda has been used in both in-vivo and in-vitro studies as a key biomarker for various disease patterns including hypertension, diabetes, atheroscle...

aloe vera has been used worldwide in pharmaceutical, food and cosmetic industries due to the plethora of biological activities of its constituents. this study was done to evaluate the effects of dietary aloe vera on growth and lipid peroxidation in rainbow trout (oncorhynchus mykiss). a total number of 480 o. mykiss (mean weight 9.50 ± 0.85 g) were randomized into four experimental groups inclu...

conclusions maximal and supra-maximal races induce a significant increase in lipid peroxidation and cause non-negligible inflammation and muscle damage. these effects were relatively related to the physical exercise type and the sportive specialty. results a significant increase in malondialdehyde (mda) concentrations was observed in ss and mdr after the vameval test and in ldr after the limite...

results seminal plasma tac level in normospermic men was significantly higher than asthenoteratospermic men (p < 0.001) and oligasthenoteratospermic men (p < 0.001) and had posetive correlation with sperm count, motility and morphology. in contrast mda levels in normospermic men were significantly lower than in asthenoteratospermic men (p = 0.049) and oligoasthenoteratospermic men (p = 0.001) a...

background: oxidative stress in reproductive system leads to sperm dna damage and sperm membrane lipid peroxidation and may play an important role in the pathogenesis of male infertility, especially in idiopathic cases. antioxidants such as carotenoids function against free radical damages. objective : the aim of this study was to determine the levels of lycopene, beta-carotene and retinol in s...

Effect of inorganic phosphate on ferrous ionand ascorbate-induced lipid. peroxidations of isolated rat liver mitochondria was investigated. As a result it has been shown that phosphate accelerates the ferrous ion.induced lipid peroxidation; namely, phos. phate shortens the induction lag period of the lipid peroxidation reaction but the malondialdehyde after onset of its production is yielded at...

background &amp; aim: when the level of free radicals is increased and also when both the enzymatic systems and low molecular antioxidants are not sufficient to protect the organism, it seems necessary to get antioxidants from external sources. this study aimed to evaluate the antioxidant potential of different parts of catharantus roseus experimental: the antioxidant potential of ethanol extra...

the study was designed with an aim to evaluate the protective effects of reduced glutathione on cyclophosphamide induced lipid peroxidation and also changes in cholesterol content. goat liver and white new zealand rabbit were used as lipid source for the models. lipid peroxidation study was performed by measuring the malondialdehyde, 4-hydroxy-2-nonenal, reduced glutathione and nitric oxide con...

this study was designed to explore the protective effects of ascorbic acid and water extract of spirulina platensis (blue green algae) on methotrexate-induced lipid peroxidation using goat liver as the lipid source. this in vitro evaluation was done by measuring the malondialdehyde, 4-hydroxy-2-nonenal, reduced glutathione and nitric oxide content of tissue homogenates. the study reveals the li...

4-Hydroxy-2-nonenal, an indicator of lipid peroxidation process. was used as model marker to explore ceftriaxone-induced lipid peroxidation in goat liver homogenate. Ceftriaxone was found to induce lipid peroxidation significantly. It was further found that ascorbic acid could significantly arrest ceftriaxone-induced lipid peroxidation. The results corroborate the earlier findings with malondia...
