Mongrel cats with experimental cryogenic brain lesions were treated with the carotenoid compound crocetin. It has been shown that crocetin increases the diffusion speed of oxygen through plasma, and should provide a net increase in available oxygen to the capillary endothelial cell. The treated
Purpose
We investigated the effects of oral and ocular administration of crocetin in a murine retinal vein occlusion (RVO) model. Crocetin is a type of
carotenoid contained in the fruit of gardenia (
Gardenia jasminoides Ellis) and the stigma of saffron (
CrocusExposure 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
Lipofuscin results from digestion of photoreceptor outer segments by the retinal pigment epithelium (RPE) and is the principal compound that causes RPE fluorescence during autofluorescence imaging. Absorption of the 488-nanometer blue light by macular pigments, especially by the carotenoids lutein
Mechanisms of the potent anti-inflammatory actions of carotenoids are unknown. Since carotenoids are incorporated into membranes, they might modulate transient receptor potential ankyrin 1 and vanilloid 1 (TRPA1 and TRPV1) activation predominantly on peptidergic sensory nerves. We therefore
BACKGROUND
meso-Zeaxanthin (MZ) is a xanthophyll carotenoid with profound antioxidant activity.
OBJECTIVE
Oxidative stress plays a decisive role in numerous degenerative diseases including cancer. The present study evaluates anti-inflammatory effect of MZ.
METHODS
Balb/c mice were treated with
Astaxanthin is a carotenoid pigment that possesses potent antioxidative, anti-inflammatory, antitumor, and immunomodulatory activities. Previous studies have demonstrated that astaxanthin displays potential neuroprotective properties for the treatment of central nervous system diseases, such as
Bixin is the main natural apocarotenoid extracted from the seeds of Bixa orellana, widely used as a cosmetic and textile colorant. Despite the description of several pharmacological properties of B. orellana extracts, little has been studied regarding the pharmacological properties of
OBJECT.: Aneurysmal subarachnoid hemorrhage (SAH) causes devastating rates of mortality and morbidity. Accumulating studies indicate that early brain injury (EBI) greatly contributes to poor outcomes after SAH and that oxidative stress plays an important role in the development of EBI following SAH.
The paper evaluates the clinical effectiveness of Vitrum Vision ("Unifarm") that contains a complex of carotenoids, vitamins, and trace elements, which is adapted to ocular tissue metabolic features, in the tired eye syndrome and senile macular degeneration. The use of Vitrum Vision in patients with
OBJECTIVE
Macular pigment (MP) is the collective name for three isomeric carotenoids: lutein, zeaxanthin, and meso-zeaxanthin. Macular pigment density is greatest in the central retina, peaking at the fovea and falling to negligible levels at 7 degrees of eccentricity from the fovea. Several studies
In Indian traditional medicine, peacock feather in the form of ash (Bhasma) or water extract are used against snakebite and to treat various problems associated with lungs. This study was aimed to evaluate the water extract of peacock feather (PCF) against the local tissue damage caused due to
Hyperinduced oxidant stress may have a role in the pathogenesis of diabetes and its micro- and macrovascular complications. Attaining euglycemia and the use of antioxidant vitamins could reduce oxidant stress and complications. In general, evidence does not support the use of supplements, and
OBJECTIVE
Lutein is one of the most common carotenoids defined in human plasma as having potent anti-oxidant effects. We aimed to determine the biochemical and histopathological effects of lutein on cisplatin-induced oxidative retinal injury in rats.
METHODS
Twenty-four rats were equally divided
Lycopene is a naturally occurring carotenoid found abundantly in red fruits and vegetables. Myriads of literature documented potential health benefits of lycopene, owing to its sublime capacity of suppressing oxidative stress, inflammation, and modulation of various cell survival pathways. Due to
