BACKGROUND AND AIM Carotenoids in plasma are inversely associated with cardiovascular risk. Low levels can be explained by low dietary intake but also by a number of other factors including inflammatory activity. Given that matrix metalloproteinase (MMP)-9 has an important role in inflammation and cardiovascular disease, we hypothesized that circulating MMP-9 levels would be inversely related t...
Fruits and vegetables that are sources for lutein and zeaxanthin: the macular pigment in human eyes.
BACKGROUND It has been suggested that eating green leafy vegetables, which are rich in lutein and zeaxanthin, may decrease the risk for age related macular degeneration. The goal of this study was to analyse various fruits and vegetables to establish which ones contain lutein and/or zeaxanthin and can serve as possible dietary supplements for these carotenoids. METHODS Homogenates of 33 fruit...
BACKGROUND Retinoids (derivatives of vitamin A) are reported to reduce the occurrence of some second primary cancers, including aerodigestive tract tumors. In contrast, beta-carotene does not reduce the occurrence of primary aerodigestive tract cancers. Mechanisms explaining these effective retinoid and ineffective carotenoid chemoprevention results are poorly defined. Recently, the all-trans-r...
Carotenoids are one of the most important and widely distributed pigments in nature and have essential biological functions in organisms. They also impart distinctive and attractive coloration to the breeding animals. Over the past two decades, application of microbial carotenoids has attracted the attention of researchers due to their natural and economic advantages. However, carotenoid prod...
One of the most important characteristics of fruit crops is susceptibility to decay and quality reduction during storage life. Crops with higher antioxidant capacity are tolerant to stress and have greater nutritional quality and storage life. Hence, to investigate the antioxidant capacity of two grape cultivars Ghezel uzum and Red hosseini a factorial experiment with 3 replications was carried...
A pot experiment was conducted to evaluate the effect of foliar spray of salicylic acid (0, 50, 100 ppm), ascorbic acid (0, 100, 200 ppm) and thiamine (0, 50, 100 ppm) on vegetative growth, flowering and photosynthetic pigments of marigold (Calendula officinalis L.) plants at greenhouse of SB University of Kerman, Iran. Results showed that application of salicylic acid and thiamine inc...
Background: Retinoids (derivatives of vitamin A) are reported to reduce the occurrence of some second primary cancers, including aerodigestive tract tumors. In contrast, b-carotene does not reduce the occurrence of primary aerodigestive tract cancers. Mechanisms explaining these effective retinoid and ineffective carotenoid chemoprevention results are poorly defined. Recently, the all-trans-ret...
OBJECTIVE(S) Carotenoids which are naturally synthesized by fungi such as yeasts can act as an antioxidant which is closely related to their ability to decrease the risk of a variety of degenerative diseases. In recent years, the increase of demand for carotenoids obtained from natural sources has promoted major efforts to improve carotenoid production from biological sources such as pigmented ...
