The widespread application of biostimulants with a growing trend represents sustainable practices aimed at improving growth and yield alleviating stresses in green agricultural system. Phthalanilic acid (PPA), biostimulatory functions, has been increasingly applied to fruit vegetable production. However, its specific effects on development cowpea (Vigna unguiculata) plants is still unclear. In ...
This paper focuses on the development of a processing scheme to obtain a water-soluble natural yellow colourant from Opuntia fruits for application in food, paying special attention to the extraction procedure. Edible yellow Opuntia fruits grown in Murcia (Spain) were homogenized and extracted with ethanol, water, or ethanol/water (60:40) solvents. Pigment extract was chemically characterized a...
Maya Blue, a pigment used by the Mayas in Yucatan, is remarkably stable: the color is not destroyed by hot concentrated mineral acids or by heating to about 250 degrees C. The principal constituent is the colorless mineral attapulgite. It is proposed that the pigment is an adsorption complex of attapulgite and natural indigo; a synthetic equivalent may be prepared from attapulgite and either in...
Human gallbladders with cholesterol stones exhibit impaired muscle contraction induced by agonists that act on transmembrane receptors, increased membrane cholesterol content, and abnormal cholesterol-to-phospholipid ratio compared with those with pigment stones. The present study was designed to investigate the functions of the CCK receptor of gallbladder muscle membranes by radioreceptor assa...
abstract background: transpupillary thermotherapy is a new treatment for subfoveal choroidal neovascularization which needs further evaluation. this study was aimed to evaluate the efficacy of transpupillary thermotherapy on regression of occult subfoveal choroidal neovascularization with or without pigment epithelial detachment in patients with age-related macular degeneration. methods: in a c...
background: there is a growing demand for mass production of shikalkin (a natural pigment consisted of shikonin and alkannin) due to its increasing applications in cosmetics, pharmaceutical and nutrition industries. the root of iranian arnebia euchroma produces shikalkin. the promising capability of this plant for shikalkin production has already been demonstrated in cell culture studies. objec...
Chlorosomes are large light-harvesting complexes found in three phyla of anoxygenic photosynthetic bacteria. Chlorosomes are primarily composed of self-assembling pigment aggregates. In addition to the main pigment, bacteriochlorophyll c, d, or e, chlorosomes also contain variable amounts of carotenoids. Here, we use X-ray scattering and electron cryomicroscopy, complemented with absorption spe...
Changes in the biosynthesis of individual carotenoid pigments have been investigated during fruit ripening of five cultivars of red pepper (Capsicum annuum L.): Mana, Numex, Belrubi, Delfin, and Negral (a chlorophyll-retaining mutant when ripe). The study was carried out throughout the ripening process, and with special emphasis on the ripe stage, to discover possible differences between cultiv...
sodium bentonite can bind to dietary pigment and decreases yolk color scale. sodium bentonite is one of the main parts of formycine® gold, the effect of different levels of formycine® gold and dietary pigment on egg quality, egg yolk color and performance criteria of laying hens from 26 to 34 week of age were studied. one hundred ninety two hy-line hens were divided into 24 groups of 8 birds ea...
persian shallot (allium altissimum regel.) is one of the perennial medicinal and industrial plant which is naturally growing in high elevated lands. in order to evaluate the effects of different nutrient elements such as nitrogen, phosphorus and potassium on photosynthetic rate and pigment content of persian shallot; an experiment was conducted as factorial based on completely randomized design...
