The Green Microalga var. (Scenedesmaceae, Chlorophyta) Isolated from an Algerian Hot Spring as a Potential Source of Fatty Acids.

Screening microalgae from extreme environments, including hot springs, is an important research topic that has lately emerged. A thermophilic green alga was isolated from a north-eastern Algerian hot spring at a temperature of 63 °C, and its fatty acid (FA) profile was explored. The strain was cultivated in BBM medium at 35 °C in a 16:8 h light/dark cycle and 75 μM photons m s.

Daily rhythms in the morphometric parameters of hepatocytes and intestine of the European sea bass (Dicentrarchus labrax): influence of feeding time and hepatic zonation.

The digestive system presents daily rhythms at both physiological and histological levels. Although cell morphology rhythms in mammals have been reported, they have scarcely been investigated in fish. The aim of the present research was to investigate the existence of daily rhythms in the morphology of cells in the liver and intestine of a teleost fish, the European sea bass (Dicentrarchus labrax), and how feeding time influences them.

Effects of long-term ingestion of white tea on oxidation produced by aging and acute oxidative damage in rats.

The infusion tea extracted from the leaves of the plant Camellia sinensis can be used in the prevention of cancer, cardiovascular and neurodegenerative diseases, and aging, while adriamycin (ADR) is an anticancer drug that increases oxidative stress in cells. The present study evaluated the protective effect of the long-term consumption of white tea used at two different doses against the oxidative stress produced by aging and acute oxidation caused ADR treatment. At wearing, rats received distilled water (control), or 0.

[STRATEGIES TO IMPROVE THE NUTRITIONAL AND HEALTH CHARACTERISTICS OF MEAT PIE OF MURCIA].

Objectives: improvement of the nutritive quality and healthy properties of the meat pie of Murcia (MMP), maintaining its appreciated organoleptic quality and the design of a functional MMP through the addition of a natural ingredient rich in fructooligosaccharides.

Methods: different formulations of the MMP (healthy MMP and functional MMP) have been elaborated by changing the type and amount of some of its ingredients. The nutritional composition, the caloric value, the fatty acid profile and the fat quality have been determined.

EFFECT OF LONG TERM INTAKE OF WHITE TEA ON ACUTE OXIDATIVE STRESS IN RATS.

Introduction: the well known antioxidant properties of white tea include the prevention of cancer, neurodegenerative diseases and oxidative stress. Adriamycin can generate an amount of oxidative stress in vivo.

Objective: evaluate long term intake of white tea on plasma antioxidant capacity and on the fatty acid profile of liver and heart microsomes in animals subjected to acute oxidative stress.

The freshwater alga Chroothece richteriana (Rhodophyta) as a potential source of lipids.

During an ecological study of Chroothece (Rhodophyta) in a small river in a semi-arid region of south-east Spain it became clear that most of these cells had a high lipid content. This suggested potential uses in biotechnology, which has been investigated further. The colonies, which occur in full sunlight, are typically orange-brown.

Chemical and functional properties of the different by-products of artichoke (Cynara scolymus L.) from industrial canning processing.

In this study, the basic chemical composition and functional properties of six by-product fractions collected from different steps of artichoke industrial processing were evaluated. Fractions differed in thermal treatment, the bract position in the artichoke head and the cutting size. Contents of moisture, ash, protein, fat, dietary fibre, inulin, total phenolics, total flavonoids, caffeoyl derivatives and flavones were analysed.

[Characterization and nutritional value of a food artisan: the meat pie of Murcia].

Objectives: The main aims of this study are to describe the characteristics of the meat pie, a typical product of the regional gastronomy of Murcia and to determine its nutritional and energy values, fatty acid profile and fat quality.

Methods: There were studied 24 samples of Murcia's meat pie from the six best-selling retail establishments in this Region (four units per establishment).The moisture, protein, fat, carbohydrates, fibre and minerals, contents and the energy value, fatty acid profile and fat quality were analyzed using the Official Analysis Methods of Foods.

Protective effect of white tea extract against acute oxidative injury caused by adriamycin in different tissues.

Adriamycin (ADR) is an anticancer agent that increases oxidative stress in cells. We evaluated the protective effect of the long term consumption of white tea at two different doses against this drug. For this purpose rats were given distilled water (controls), 0.

Coastal fish farms are settlement sites for juvenile fish.

Two south-west Mediterranean fish farms were monitored over a period of 22 months to test if sea-cage fish farms act as settlement habitats for juvenile fish. Twenty juvenile fish species were found to settle at farms throughout the year. Fish assemblage composition varied markedly over time and was dependent on the spawning period for each species.

Mycobiota of the date palm phylloplane: description and interactions.

We have analysed the mycobiota of date palm (Phoenix dactylifera, L.) leaves using several techniques. Profusely sporulating fungi (Penicillium spp.

Changes in body condition and fatty acid composition of wild Mediterranean horse mackerel (Trachurus mediterraneus, Steindachner, 1868) associated to sea cage fish farms.

Net-cage fish farms attract a great number of wild fishes, altering their behaviour and possibly their physiology. Wild Mediterranean horse mackerel (Trachurus mediterraneus), sampled from populations aggregated around two Mediterranean fish farms and from two natural control populations, were analyzed for differences in body condition, stomach content and fatty acid composition. Pellets used to feed caged fish in both farms were also analyzed to identify their relationship with the fatty acid composition of tissue of wild fish.
