Comparative study of the antioxidant activity of the essential oils of five plants against the HO induced stress in Saccharomyces cerevisiae.

The purpose of this work was to investigate the protective effect of five essential oils (EOs) Benth. Labill. L.

Physicochemical Evaluation of Edible Cyanobacterium Collected from the South Atlantic Coast of Morocco: A Promising Source of Dietary Supplements.

The cyanobacterium -a genus of nonheterocystous filamentous cyanobacteria-is used in industrial applications and as a food supply. The current research work aims to study the physicochemical characteristics of indigenous to the Moroccan Atlantic coast at Laayoune (Foum El Oued lagoon). The contents of proteins, carbohydrates, vitamins, lipids, minerals, heavy metals, energy value, humidity, ash, pigments, and tannins in were investigated using protocols as described in the earlier literature.

Evaluation of Moroccan microalgae: Spirulina platensis as a potential source of natural antioxidants.

Background Ethanolic, aqueous and lipidic extracts of Spirulina platensis were evaluated for their bioactive substances (polyphenols and fatty acids) and antioxidant activities using two different assays diphenyl-1-picrylhydrazyl (DPPH) and azino-bis (ethylbenzthiazoline-6- sulfonicacid (ABTS)). Methods The phenolic compounds amounts were determined by colorimetric assays and were analyzed by high-performance and liquid chromatography (HPLC) method. The identification of phenolic compounds in the extract was accomplished by comparison of their retention times with those of pure standards.

Antioxidant-rich food intakes and their association with blood total antioxidant status and vitamin C and E levels in community-dwelling seniors from the Quebec longitudinal study NuAge.

A cross-sectional study was designed to investigate the association between current consumption of a series of 26 common antioxidant-rich foods (ARF) with serum total antioxidant status (TAS) and plasma vitamin C and E levels in community-dwelling older adults. A convenience sample of the first 94 non-smoking Caucasian men (54%) and women (46%) enrolled in the Quebec Longitudinal Study NuAge were selected. The "Functional Foods Consumption Frequency Questionnaire" (FFCFQ) was administered at recruitment (T1) to ascertain patterns of consumption of ARF over the lifetime.

Antiatherogenic activity of extracts of Argania spinosa L. pericarp: beneficial effects on lipid peroxidation and cholesterol homeostasis.

Prevention of lipoprotein oxidation by natural compounds may prevent atherosclerosis via reducing early atherogenesis. In this study, we investigated for the first time the beneficial properties of methanolic extract of argania pericarp (MEAP) towards atherogenesis by protecting human low-density lipoprotein (LDL) against oxidation while promoting high-density lipoprotein (HDL)-mediated cholesterol efflux. By measuring the formation of malondialdehyde (MDA) and conjugated diene as well as the lag phase and the progression rate of lipid peroxidation, the MEAP was found to possess an inhibitory effect.

Effect of PON1 polymorphism on HDL antioxidant potential is blunted with aging.

Paraoxonase1 is a HDL-associated enzyme, which is responsible for their antioxidant property. This study was aimed to investigate the effect of PON1 [Q192R] and [L55M] genotypes on susceptibility of LDL and HDL to lipid peroxidation and on antioxidant activity of HDL as a function of aging. Seventy-eight healthy subjects distributed in two age groups, young (20-30 years) and elderly (60-89 years) were recruited.

Marrubium vulgare extract inhibits human-LDL oxidation and enhances HDL-mediated cholesterol efflux in THP-1 macrophage.

The objective of the present study was to elucidate the beneficial properties of aqueous extracts of Marrubium vulgare (AEM) towards cardiovascular disease by protecting human-LDL against lipid peroxidation and promoting HDL-mediated cholesterol efflux. Human-LDL were oxidised by incubation with CuSO(4) in the presence of increased concentrations of AEM (0-100 microg/ml). LDL lipid peroxidation was evaluated by conjugated diene formation, vitamin E disappearance as well as LDL-electrophoretic mobility.

Argan oil: which benefits on cardiovascular diseases?

Aim: The argan oil, extracted from argan-tree fruits, has been known for its various pharmacological properties and used as a natural remedy since several centuries. In this review, we present a summary of the results obtained from a survey of the literature on argan oil.

Data Synthesis: Various studies conducted in vitro or on human and animal models suggest that argan oil could play a beneficial role in cardiovascular diseases prevention and its consumption could protect against atherosclerosis and cancer via a variety of biological mechanisms.

Consumption of argan oil may have an antiatherogenic effect by improving paraoxonase activities and antioxidant status: Intervention study in healthy men.

Background And Aim: Due to its high antioxidant and mono- and polyunsaturated fatty acid content virgin argan oil (VAO) could play a beneficial role in cardiovascular prevention. We were therefore interested in determining whether the consumption of VAO could improve plasma paraoxonase (PON1) activities and antioxidant status in healthy men.

Methods And Results: Sixty young men were included in this interventional study.

Evidence of hypolipemiant and antioxidant properties of argan oil derived from the argan tree (Argania spinosa).

Background: Virgin argan oil is of interest in cardiovascular risk prevention due to its fat composition and antioxidant compounds.

Aims: We investigated with Moroccan subjects the effect of regular virgin argan oil consumption on lipid profile and antioxidant status and the in vitro effect of argan oil minor compounds (tocopherols, sterols and polyphenols) on LDL peroxidation.

Design: Healthy subjects (20 men, 76 women) were studied.
