Three pineapple cultivars smooth cayenne, Tainung 17, and 19 were processed into flesh, peel, stem. Nine samples analyzed for their proximate compositions bromelain activity existed in water extracts. Pineapple fleshes rich reducing sugars soluble fiber whereas peel stem crude fiber. Stem showed higher (102–247.3 U/mg). All 18 including ethanol extracts quite effective the scavenging ABTS+- DPP...

Metastasis by cancer cells relies upon the acquisition of the ability to evade anoikis, a cell death process elicited by detachment from extracellular matrix (ECM). The molecular mechanisms that ECM-detached cancer cells use to survive are not understood. Striking increases in reactive oxygen species (ROS) occur in ECM-detached mammary epithelial cells, threatening cell viability by inhibiting ...

background: blood is permanently exposed to oxidation stress and therefore has a high antioxidants capacity. many different factors increasing the demand for the antioxidant capacity can be observed in the stored blood of donors. consequently, damage to erythrocytes by free radicals may occur. so it is useful to control the alternation of anti-oxidant enzymes in stored blood at different days o...

the number of patients with end-stage renal disease is growing rapidly in asia. patients with end stage renal disease failure (esrd) undergoing long term hemodialysis (hd) are at risk for high oxidative stress. there is paucity of information with regard to oxidative stress during hd. therefore, the aim of the present study was to evaluate catalase enzyme activity in erythrocytes and the total ...

Preterm infants are vulnerable to the oxidative stress due to the production of large amounts of free radicals, antioxidant system insufficiency, and immature oligodendroglial cells. Reactive oxygen species (ROS) play a pivotal role in the development of periventricular leukomalacia. The three most common ROS are superoxide (O2(•-)), hydroxyl radical (OH(•)), and hydrogen peroxide (H2O2). Under...
