1. The cross-talk of iron and ascorbate -Complexation and intracellular regulation of transport in human enterocytes
Sammanfattning : Iron deficiency is a serious health issue in developing countries and also in vulnerable groups of the industrialized world. There are several ways to address this issue. The present approach was to learn more about the basic mechanisms of iron uptake in the presence of ascorbate, one of the best enhancers of iron absorption. LÄS MER
2. Ascorbate in the ocular lens
Sammanfattning : Purpose: First, we intended to establish a method for sample preparation for measurement of ascorbate in whole rat and guinea pig lenses utilizing ultrafiltration and high performance liquid chromatography with ultraviolet radiation detection. Then, we aimed to investigate whether, in the albino rat, lens ascorbate concentration depends on solid dietary intake. LÄS MER
3. The xanthophyll cycle, its enzymes, pigments and regulation
Sammanfattning : The xanthophyll cycle involves the light-dependent and reversible conversion of violaxanthin to zeaxanthin. Zeaxanthin has been implicated in the protection of the photosynthetic machinery from over-excitation. The enzyme violaxanthin de-epoxidase catalyses the conversion of violaxanthin to zeaxanthin.

4. Role of intermediate filaments and expression of GFAP and S-100 in astrocytes
Sammanfattning : Astrocytes participate in a variety of important physiologic and pathologic processes in the central nervous system (CNS). One of the most remarkable characteristics of astrocytes is their vigorous response to CNS injuries. LÄS MER
5. Ultraviolet radiation cataract development and ascorbate supplementation
Sammanfattning : Background: Cataract is the major cause of blindness in the world, and long-term solar ultraviolet radiation (UVR) is a major risk factor. The pathogenesis of UVRinduced cataract is studied in various animal models and cell systems. LÄS MER
