Exposure of human skin to ultraviolet (UV) radiation causes significant damage to that tissue. The effects of UV on the skin mainly include acute inflammation (erythema/edema) and abnormal keratinization wherein prostaglandin E2 (produced by cyclooxygenase-2), interleukin-8 and transglutaminase 1 (a
Generation of singlet oxygen by solar ultraviolet (UV) radiation causes acute inflammatory responses in the skin. Accumulation of singlet-oxygen-quenching antioxidants in the skin can suppress this photo-oxidative stress. This study evaluated the effect of dietary xanthophylls from red paprika fruit
Leaf color in some individuals of Cistus creticus turns transiently to red during winter, while neighboring individuals occupying the same site remain green. We have examined whether anthocyanin accumulation can be associated with variations in photosynthetic and/or photoprotective characteristics
Two experiments were conducted to investigate the influence of caponization on skin pigmentation. Male broiler chicks were divided into caponized, sham-operated, and intact treatment groups with surgery performed at 3 weeks of age (Experiment 1) or 1 week of age (Experiment 2). All chicks were
Three hundred sixty 1-d-old Ross 308 male broilers were used to study the effects of broccoli stem and leaf meal (BSLM) on growth performance, skin pigmentation, antioxidant function, and meat quality. The chicks were fed 4 diets containing different levels (0, 4.0, 8.0, and 12.0%) of BSLM as
This study aims at investigating the effects of different grain sources during pre-hatch (from diet of the breeders) and post-hatch (from the diet of broilers) on coloration (Roche color fan scores; L*, lightness; a*, redness; and b*, yellowness) as well as the growth performance in yellow-skinned
Visible-near-infrared reflectance spectroscopy was used to predict dry matter, fat, pH, retinol, alpha-tocopherol, beta-carotene, xanthophylls, sodium chloride, calcium, potassium, magnesium, zinc, total antioxidant capacity, brightness, redness, and yellowness in both fresh and freeze-dried
