Development of a Phytomelatonin-Rich Extract from Cultured Plants with Excellent Biochemical and Functional Properties as an Alternative to Synthetic Melatonin.

Melatonin is a pleiotropic molecule with multiple and various functions. In recent years, there has been a considerable increase in the consumption of melatonin supplements for reasons other than those related with sleep (as an antioxidant, for anti-aging, and as a hunger regulator). Although the chemical synthesis of melatonin has recently been improved, several unwanted by-products of the chemical reactions involved occur as contaminants.

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.

Long-term intake of white tea prevents oxidative damage caused by adriamycin in kidney of rats.

Background: White tea infusion (Camelia sinensis) has antioxidants properties. The infusion contains polyphenols that have been proposed to induce antioxidant response element (ARE) response via nuclear factor E2-related factor 2 (NRF2). Adriamycin (ADR) has antitumour properties and oxidative effects.

Molecular mechanisms by which white tea prevents oxidative stress.

The flavonoid content of tea (Camellia sinensis) has beneficial properties in the prevention of diseases. However, the mechanisms by which white tea can protect against oxidative stress remain unclear. To shed light on this issue, rats were given distilled water (controls), 0.

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.

Identification of different nutritional status groups in institutionalized elderly people by cluster analysis.

Objectives: To apply a cluster analysis to groups of individuals of similar characteristics in an attempt to identify undernutrition or the risk of undernutrition in this population.

Setting: Seven public nursing homes in the province of Murcia, on the Mediterranean coast of Spain.

Modelling Extraction of White Tea Polyphenols: The Influence of Temperature and Ethanol Concentration.

The optimization of the extraction of natural antioxidants from white tea has fostered intensive research. This study has investigated the effects of ethanol-water mixtures, temperature and time on the extraction of polyphenols and antioxidant components from white tea. The response surface methodology was applied to identify the best extraction conditions.

[Importance of sucrose in cognitive functions: knowledge and behavior].

Sucrose is not present in the internal milieu as such, so it is physically impossible that it may have a direct influence on cognitive functions, behaviour and knowledge. However, during the digestive process, disaccharides are released into monosaccharides, in the case of sucrose into glucose and fructose, which reach the liver via the portal vein. Finally, they go into bloodstream in the form of glucose and in some cases as very low-density lipoproteins (VLDL).

Errors and myths in feeding and nutrition: impact on the problems of obesity.

The increase in obesity prevalence cannot be explained by a sudden and generalized change in human genome. It is certainly due to the modification of lifestyle habits and especially of the diet, as well as a lack of physical activity and sedentary living. Changes in the feeding pattern and the subsequent unbalance in the caloric profile of the diet may have had great importance in the occurrence of obesity.
