Tumor cells generally display low lipid peroxidation. A low content of polyunsaturated fatty acids in membrane phospholipids is a possible cause of their decreased susceptibility to lipid peroxidation. To investigate the importance of substrate availability in eliciting lipid peroxidation and to study cell viability in conditions of stimulated lipid peroxidation, AH-130 hepatoma cells were enri...

The aim of this study was to evaluate the effects of increasing doses of ascorbic acid (AA) and citric flavonoids (quercetin and rutin) on the performance and meat quality characteristics of broilers submitted to cyclic heat stress. Four-hundred one-day-old female Ross 308 were housed in 40 battery cages a in temperature controlled room. Treatments consisted of 0, 250, 500, and 1000 g/ton on of...

Primaquine and chloroquine are used for the treatment of malaria; evidence from the literature suggests that these drugs may induce oxidative stress. In this study we investigated the effects of primaquine and chloroquine on oxidative damage and DNA damage in brain, liver and kidney of rats after 7, 14 and 21 days of administration. Our results demonstrated that primaquine causes DNA damage in ...

Atlantic horse mackerel (Trachurus trachurus) fillets were coated by gallic acid and chitosan solutions, including nanoparticles, fish quality shelf life assessed during chilled storage for 13 days. All chitosan-containing coatings decreased microorganisms’ growth in more than 2 log cycles up to late stages; however, those with nanoparticles resulted be effective, probably due a greater contact...

The utilisation of Moringa oleifera leaves powder (MOLP) to improve the nutritional properties and inhibit lipid oxidation proliferation microorganisms in ground beef during cold storage was examined. effects 0.2, 0.4, 0.6, 0.8% MOLP on (proximate composition, total phenolic flavonoid content), thiobarbituric acid reactive substances (TBARS), microbial physicochemical characteristics (pH value,...

Abstract This research describes a first approach to analyse the effects of using high-pressure processing (HPP) as pre-treatment before frozen storage and subsequent canning fish. For it, Atlantic Chub mackerel (Scomber colias) was subjected HPP (200, 400 600 MPa for 2 min) followed by freezing (−30 °C 48 h), (−18 °C 0, 3, 6, 10 or 15 months), canned (3 months at 20 °C). Lipid damage developme...

Fried Mugil cephalus was investigated under optimal vacuum and atmospheric conditions. The water distribution, texture, color properties of vacuum-fried samples were enhanced compared with atmospheric-fried samples. Meanwhile, frying (VF) reduced the total oil content, protein oxidation, degradation. molecular weight amino acid content suggested that well-preserved during VF. In addition, carbo...

The study aimed to evaluate the effects of date palm spikelet extract (DPSE) from two cultivars on chemical, antioxidants, and sensory properties yogurt. DPSE Rziz (Rz) Khalas (Kl) contains high levels total phenolics flavonoids as well phenolic compounds with an antioxidant activity exceeded 90%. Increasing concentration in yogurt improved solids, protein, ash, compounds, flavonoids, even duri...
