Fourteen tropical fruits from south Florida (red guava, white guava, carambola, red pitaya (red dragon), white pitaya (white dragon), mamey sapote, sapodilla, lychee, longan, green mango, ripe mango, green papaya, and ripe papaya) were evaluated for antioxidant activity, total soluble phenolics (TSP), total ascorbic acid (TAA), total dietary fiber (TDF), and pectin. ORAC (oxygen radical absorba...

OBJECTIVES To observe if there is any connectivity between oxidative stress and cardiovascular diseases (CVDs). MATERIALS AND METHODS Patients suffering from different cardiovascular diseases (hypertension, ischemic heart disease, rheumatic heart disease) attending Manipal Teaching Hospital, Pokhara and strictly matched controls were selected for this study. Oxidative stress (OS) was measured...

Oxidative stress has been found to be associated with variety of diseases including diabetes. It is conceivable that alteration in plasma antioxidant reserve along with serum uric acid levels may have a crucial role in diabetes mellitus (DM). The objectives of present study were to ascertain the plasma levels of total antioxidant activity (TAA) and serum uric acid (UA) in diabetes mellitus and ...

Antioxidant compounds are abundantly available in plants and play an important role in scavenging free radicals, thus providing protection to humans against oxidative DNA damage. Mentha spicata Linn., commonly called spearmint, belongs to the family lamiaceae. It was selected in the present study because Mentha extracts have antioxidant properties due to the presence of eugenol, caffeic acid, r...

The authors evaluated the role of a high-protein, low-calorie, polyunsaturated fatty-acid (PUFA) -supplemented diet on anthropometric parameters, erythrocytemembrane fatty-acid composition, and plasma antioxidant defenses of nonprofessional volleyball athletes. The athletes were divided in two groups: One (n = 5) followed the Mediterranean diet, and the other (n = 6) followed a high-protein, lo...

The antioxidant potential of Actinidia macrosperma C. F. Liang (Actinidiaceae) was investigated in vitro for total phenolic content, along with total antioxidant activity (TAA), 1,1-diphenyl 2-picryl hydrazyl (DPPH), and lipid peroxidation (LP). The results indicated that different polarity extracts of A. macrosperma exhibit different biological activities, which depends mainly on the presence ...

The antifibrotic effects of traditional medicinal herb Caesalpinia sappan (CS) extract on liver fibrosis induced by thioacetamide (TAA) and the expression of transforming growth factor β1 (TGF-β1), α-smooth muscle actin (αSMA), and proliferating cell nuclear antigen (PCNA) in rats were studied. A computer-aided prediction of antioxidant and hepatoprotective activities was primarily performed wi...

BACKGROUND/AIMS Since peritoneal membrane is more compatible and residual renal function better preserved during peritoneal dialysis, we questioned whether the oxidative burden in chronic kidney disease (CKD) is influenced by dialysis modality. METHODS 49 stable CKD patients, 17 on continuous ambulatory peritoneal dialysis (CAPD), 16 on hemodialysis (HD), and 16 non-dialyzed, and 13 healthy s...

1. Based on carotenoids’ antioxidant and pro-vitamin functions, carotenoid pigmentation, particularly in birds, has been hypothesized to honestly advertize condition and health. As antioxidants, carotenoids protect the body from oxidative damage caused by internal or external stressors (e.g. growth, infection and anthropogenic pollution). However, the relative importance of carotenoids in the a...
