Abstract The longevity-homeoviscous adaptation (LHA) theory of aging states that lipid composition of cell membranes is linked to metabolic rate and lifespan, which has been widely shown in mammals and birds but not sufficiently in fish. In this study, two species of the genus Amphiprion (A. percula and A. clarkii, with estimated maximum lifespan potentials [MLSP] of 30 and 9-16 years, respectively) and the damselfish Chromis viridis (estimated MLSP of 1-2 years) were chosen to test the LHA theory of aging in a potential model of exceptional longevity. Brain, livers and samples of skeletal muscle were collected for lipid analyses and integral part in the computation of membrane peroxidation indexes (PIn) from phospholipid (PL) fractions and PL fatty acid composition. When only the two anemonefish were compared, results pointed to the existence of a negative correlation between membrane PIn value and maximum life expectancy, well in line with the predictions from the LHA theory of aging. Nevertheless, contradictory data were obtained when the two clownfish were compared to the shorter-lived C. viridis. This results along with those obtained in previous studies on fish denote that the magnitude (and sometimes the direction) of the differences observed in membrane lipid composition and peroxidation index with MLSP cannot explain alone the diversity in longevity found among fishes.

Aluminum is recognized as a public health concern because of its potential toxic effects on human health. Therefore, the present experiment was undertaken to determine the effectiveness of curcumin (CUR) in reducing the hepatotoxicity induced by aluminum chloride (AlCl3) in animals. In this experimental study, forty male rats were allocated to five groups (N = 8), viz. no treatment (control), solvent (DMSO or distilled water), CUR (10 mg/kg B.W.), AlCl3 (10 mg/kg B.W.), and CUR+AlCl3 (each with 10 mg/kg B.W.). Treatments were performed by intra-peritoneal injections for 28 days. On the final day, animals were sacrificed, and liver function markers in blood plasma, hepatic antioxidants, and lipid peroxidation index in liver homogenate were estimated. AlCl3 treatment resulted in a significant increase in plasma AST, ALT, ALP and LDH activities with decreased total protein compared to control. AlCl3 significantly reduced superoxide dismutase (SOD), catalase (CAT) and glutathione (GSH) levels but increased malondialdehyde (MDA) level in the liver compared to control. AlCl3 also caused various histopathological changes in the livers of rats. Curcumin could normalize nearly all these parameters. CUR improved levels of changes in different parameters when was combined with AlCl3. It is concluded that CUR has beneficial effects being able to antagonize AlCl3 toxicity.

Peroxidation Index

The membrane pacemaker hypothesis predicts that long-living species will have more peroxidation-resistant membrane lipids than shorter living species. We tested this hypothesis by comparing the fatty acid composition of heart phospholipids from long-living Procellariiformes (petrels and albatrosses) to those of shorter living Galliformes (fowl). The seabirds were obtained from by-catch of commercial fishing operations and the fowl values from published data. The 3.8-fold greater predicted longevity of the seabirds was associated with elevated content of peroxidation-resistant monounsaturates and reduced content of peroxidation-prone polyunsaturates and, consequently, a significantly reduced peroxidation index in heart membrane lipids, compared with fowl. Peroxidation-resistant membrane composition may be an important physiological trait for longevous species.
