Determinou-se a capacidade antioxidante de cinco antocianinas: Unilateral retinitis pigmentosa sine pigmento. A patient presented with unilateral findings of night blindness shown by impaired rod function and dark adaptation, constricted visual fields with good central acuity, a barely recordable electro-retinographic b-wave, and a unilaterally impaired electro-oculogram.

There were none of the pigmentary changes usually associated with retinitis pigmentosa. The unaffected right eye was normal in all respects. Therefore the case is most probably one of unilateral retinitis pigmentosa sine pigmento.

Nutrient and caroteniod content of stem and leaves. Se analizaron comparando hoja y tallo: An integrated characterization study of Swiss chard grown in Santiago del Estero, Fe, was carried out. As Swiss chard is a vegetable of important regional consumption, the determination of its basic constituents, minerals and pigments was done to appraise the nutritional value offered by this food in our area.

Moisture, ash content, proteins, fats, available carbohydrates, total dietary fiber, chlorophylls and carotenoids were analysed, comparing the leaves and the stems. As to minerals, calcium, magnesium, sodium, manganese, zinc, iron, phosphorous, potassium, and boron were determined. Differences in the concentration of minerals, proteins, fats and fiber between the leaves and the stems were found, as well as the carotenoid content mainly in the leaves.

These findings revealed important differences in energy content and provitamin A value, showing that the stem. Full Text Available El cultivo de cianobacterias, como Arthrospira, puede realizarse en sistemas abiertos y sistemas cerrados o fotobiorreactores. Studies on carotenoids and oxidative stability of winter squash seed and soybean oils.

Full Text Available Winter squash seed and soybean oils were extracted with commercial hexane. Carotenoids and other pigments m the oils were studied using spectrophotometric and thin layer chromatographic analysis. Three types of pigments were identified: Carotenoids content were 70, 60, 0 ppm in crude, refined and bleached winter squash seed oil, and 80, 65, 0 ppm in crude, refined and bleached soybean oil respectively.

Stability was evaluated for crude, refined and bleached winter squash seed fotosintetivos soybean oils and an 1: Mixing winter squash seed oil with soybean oil increased the stability of soybean oil. Crude oil showed greater stability than refined and bleached oils.

Los contenidos en carotenoides fueron 70, 60, 0 ppm en aceite de semilla de calabaza de invierno crudo, refinado y decolorado, y 80, 65, 0 ppm en aceite de soja crudo, refinado y decolorado respectivamente. Se ha evaluado la estabilidad de aceites de semilla de calabaza de invierno, soja y una mezcla 1: Lipids, fatty acids composition and carotenoids of Chlorella vulgaris cultivated in hydroponic wastewater. Full Text Available Alternative culture media have been evaluated for the cultivation of microalgae, among them are, industrial and agriculture wastewaters, that make residue recycling possible by bioconverting it into a rich, nourishing biomass that can be used as a feeding complement in aquaculture and in diverse areas.

The objective of this research is to determine the lipid, fatty acid profile and carotenoid produced by the microalgae Chlorella vulgaris cultivated in a hydroponic wastewater, with different dilutions. The results showed that lipid contents did not present significant differences. Fatty acids were predominantly For total carotenoidsfotosinteticoos dilution of hydroponic wastewater did not stimulate the production of these pigments.

Influencia de la composici?? Se ha estudiado la influencia de la composici?? Se ha determinado que la fracci?? Frutos tropicales como fuente de carotenoides: Full Text Available Los carotenoides son compuestos sintetizados a partir del isopentenil difosfato y pueden ser encontrados en una gran diversidad de frutos. In recent years, the results of sxtraccion studies have suggested a positive beneficial relationship between a vegetarian-based diet and low incidence of diseases, including coronary heart disease, cancer, obesity, dental caries, and osteoporosis.

In this regard there is a need to evaluate the carotenoid content of foods. Legumes are one of the staple components of a vegetarian diet. This review specifically surveys the prevalence of carotenoids in food and forage legumes.

Se realiza un estudio del proceso de secado de dos variedades de pimiento pimentonero Capsicum annuum L. Plastids and Carotenoid Accumulation. Plastids are ubiquitously present in plants and are the organelles for carotenoid biosynthesis and storage. Based on their morphology and function, plastids are classified into various types, i. All plastids, except proplastids, can synthesize carotenoids. However, plastid types have a profound effect on carotenoid accumulation and stability.

In this chapter, we discuss carotenoid biosynthesis and regulation in various plastids with a focus on carotenoids in chromoplasts. Plastid transition related to carotenoid biosynthesis and the different fotoslnteticos of various plastids to sequester carotenoids and the associated sepatacion on carotenoid stability are described in light of carotenoid accumulation in plants. Key to Xenobiotic Carotenoids. The listed carotenoids with Fotosinteticks atoms demonstrate that the classical division of carotenoids into hydrocarbon carotenoids C,H and xanthophylls C,H,O has become obsolete.

We believe these are the first such cases reported in the literature. We describe the presenting symptoms and management, including cryotherapy, scleral buckling procedure, and sulfur hexafluoride injection SF6resulting in stable visual acuity in one case and retinal reattachment and improved visual acuity in the other case.

Multifocal amelanotic conjunctival melanoma and acquired melanosis sine pigmento. Clinical and histopathological features of four cases of multifocal amelanotic malignant melanoma of the conjunctiva in association rxtraccion ‘acquired melanosis sine pigmento ‘ are reported. The absence separacon conjunctival pigmentation in this extremely rare combination of lesions prevented early diagnosis and clinical monitoring.

As a result orbital exenteration was required in three cases. This multicentric non-pigmented variety of conjunctival malignant melanoma tends to present later than pigmented forms and may require exenteration of the orbit as a primary procedure. We present a dermal melanocytosis with superimposed nevus spilus on the ee of a 5-year-old boy. We recently introduced a new type of phacomatosis, which we termed “phacomatosis pigmentopigmentalis,” that is analogous to phacomatosis pigmentokeratotica or pigmentovascularis, for describing the association of two pigmented nevi.

The present case is fotosinteticoz example of this type of phacomatosis, which now we prefer to define phacomatosis pigmento -pigmentaria according to the correct Latin terminology.
