xanthophyll/hypoxia

CONCLUSIONS Green fruits display a high engagement in CEF and enhanced VAZ cycle activity as a response to the demands imposed by their internal aerial conditions, particularly low O 2 , due to gas exchange limitations. In the present study, we used HPLC analysis, post-illumination changes in

A water culture experiment was conducted to study the relationship between photosynthetic thermal dissipation and xanthophyll cycle in cucumber seedling leaves under hypoxia stress (the dissolved oxygen concentration in nutrient solution was 0.9-1.1 mg x L(-1)). Under the hypoxia stress, there was a

Aims: Hepatic stellate cells (HSCs) play an essential role in the development of liver fibrosis by producing extracellular matrix proteins, growth factors, and pro-inflammatory and pro-fibrogenic cytokines once activated. We previously

OBJECTIVE The aim of the study was to provide new data that add to the understanding of diabetic retinopathy and its treatment by photocoagulation. METHODS Using a spectrometric method, the reflection spectra of the macula in six type II diabetics with proliferative diabetic retinopathy were

BACKGROUND In the violaxanthin (V) cycle, V is de-epoxidized to zeaxanthin (Z) when strong light or light combined with other stressors lead to an overexcitation of photosystems. However, plants can also suffer stress in darkness and recent reports have shown that dehydration triggers

Lutein is a member of the xanthophyll family of carotenoids, which are known to prevent hypoxia-induced cell damage in the eye by removing free radicals. However, its role in other tissues is controversial, and the effects of lutein on bone tissues are unknown. To identify a possible role of lutein

Retinal pigment epithelial (RPE) cells are central to retinal health and homoeostasis. Oxidative stress-induced damage to the RPE occurs as part of the pathogenesis of age-related macular degeneration and neovascular retinopathies (e.g., retinopathy of prematurity, diabetic retinopathy). The

The objective of this study was to determine if astaxanthin (ASTX), a xanthophyll carotenoid, can prevent obesity-associated metabolic abnormalities, inflammation and fibrosis in diet-induced obesity (DIO) and nonalcoholic steatohepatitis (NASH) mouse models. Male C57BL/6J mice were fed a low-fat
