OBJECTIVE To evaluate the effects of a rose hip powder (Hyben Vital(®)) made from seeds and shells on cell senescence, skin wrinkling, and aging. METHODS A total of 34 healthy subjects, aged 35-65 years, with wrinkles on the face (crow's-feet) were subjected to a randomized and double-blinded clinical study of the effects of the rose hip powder, as compared to astaxanthin, a well-known remedy...

among the ways of pigment production, microbial synthesis has gained more interest for high growth rate, easy extraction and high yield. pigments are used in the food industry as natural colorants and preservatives; they also have pharmaceutical applications. in this study, fungus monascus purpureus ptcc 5303 was used to produce red, orange and yellow pigments. at first, significant variables w...

Congo red absorption is generally considered a contraindication of Rhizobium. However, R. leguminosarum takes up the dye on yeast extract-mannitol agar. The uptake of congo red varies among strains of R. leguminosarum, as shown elsewhere with strains of R. trifolii and R. meliloti. Congo red absorption does not distinguish rhizobia from other bacteria, but may be useful as a strain marker.

MASTERS, ANNE M., A. J. LESLIE, AND 1. KALDOR. Red cell and plusma volume development in newborn rats measured with double label. Am. J. Physiol. 222( 1) :49-54. 1972.--Plasma volume and red cell volume were measured in rats of age groups between birth and day 30 postpartum, using an intravenous marker mixture of ;“Fe-labeled red cells and radioiodinated human serum albumin ( IUHSA). In prelimi...

The aim of the present study was to evaluate the antidepressant activity of the ethanolic extract of roots of Hibiscus rosa sinensis (HRS). The extract was tested on rats and mice at doses level of 250 and 500 mg/kg, Fluoxetine was used as a standard drug at dose of 15 mg/kg, by using forced swimming test, tail suspension test and open field test. HRS extract at dose level of 500 mg/kg caused h...

A new isolate from medicinal plant endophytes was identified as Penicillium sp. (HKUCC 8070). A water-soluble red pigment was produced by this strain in potato-dextrose broth, maltextract broth and a chemically defined medium containing glutamate as a nitrogen source. The red pigment produced was identified as heat-stable, polyketide Monascus red pigment. The highest yield of the red pigment wa...

Regular and moderate wine consumption is one of the explanations suggested for the lower incidence of cardiovascular events in France compared with other industrialized countries. We evaluated whether alcohol alone or combined with red wine polyphenols reduced plaque size and/or attenuated thrombotic reactivity at the site of advanced atherosclerotic lesions. Red wine extract, or purified (+)-c...
