ABSTRACT Background: Higher intake of certain vitamins may protect against cochlear damage from vascular compromise and oxidative stress, thereby reducing risk of acquired hearing loss, but data are limited. Objective: We prospectively examined the relation between carotenoids, vitamin A, vitamin C, vitamin E, and folate intake and risk of self-reported hearing loss in women. Design: This prospective cohort study followed 65,521 women in the Nurses’ Health Study II from 1991 to 2009.

Global market is flooded with vitamin-enriched foods, mainly beverages. Major vitamins for enriching beverages are the antioxidant vitamins A, C and E. Ascorbic acid is readily oxidized and lost during storage of the beverages, at rates depending on the conditions of storage. This fact is of great importance for the consumer who must know how to store beverages and when to consume them in order to get the maximum benefit of added vitamin C. The objective of this paper was to determine the amount of ascorbic acid lost in beverages applying different preservation methods and storage condition. B

Vitamin E was identified as a lipophilic compound essential to maintain rat pregnancy. Low vitamin E intake during early pregnancy associates with congenital malformations and embryonic loss in animals and with miscarriage and intrauterine growth restriction in humans. Vitamin E protects cell membranes from lipoperoxidation and exerts non-antioxidant activities. Its function can be restored by vitamin C; thus, intake and circulating levels of both micronutrients are frequently analyzed together. Although substantial vitamin E inadequacy was reported worldwide, its consumption in Latin America

Abstract. Fruits and vegetables are rich in vitamin C with antioxidant properties which are known to influence bone quality. This study evaluated whether vitamin C (1000 mg/L) added to drinking water reverses the bone loss in ovariectomized rats.

Abstract Introduction During evolution, some species including humans, monkeys and fruit bats lost the ability for ascorbic acid (AA) biosynthesis due to inactivation of the enzyme l-gulono-lactone oxidase (GLO) and subsequently became dependent on dietary vitamin C. There are four current hypotheses in relation to the benefit of vitamin C dependence in the context of adaptation and reproduction. Here we advance and test a new ‘electron transfer hypothesis’, which focusses on the role of the expression of glucose transporter 1 (Glut-1) in red blood cells (RBCs) in recycling vitamin C, thereby

Commercial food processing has had a significant impact on reducing food spoilage and increasing accessibility to nutrient-dense vegetables. The commercial freezing process, in particular, has given producers the ability to store vegetables with minimized risk of microbial and enzymatic spoilage. Despite the effectiveness of freezing as a preservation method, there is evidence that pre-freezing procedures and prolonged storage can reduce the concentration of vitamins present within certain vegetables.

Dimyristoylphosphatidylcholine liposomes containing different concentrations of vitamin E (0, 5, 15 and 25%) were prepared by extrusion through 100 nm pore size filters, and stored at 5 °C in the dark under an oxygen atmosphere. The physico-chemical characteristics chosen as shelf life indicators for this vitamin E-carrier system were vitamin E fluorescence, mean diameter of the system, products of phospholipid oxidation and total products of lipid degradation. Encapsulated vitamins underwent an exponential degradation process (first order kinetics). The complete alteration of the system was c

Lemongrass and cinnamon essential oils (LEO and CEO) are natural oils with high anti-oxidation capacity, pleasant flavour, and various health benefits. Their ability to preservevitamin C and flavour in jam have not been tested. In this study the performance of twoessential oils (EOs) in preserving vitamin C and improving jam flavour were investigated.The EOs were produced by hydro-steam distillation of fresh lemongrasses and cinnamonleaves using a Clevenger apparatus. Jam samples were dosed with various concentrationsof either single or mixed EOs and then stored at either room or refrigeration

In this study, the protective effects of processing conditions and antioxidants on vitamin A in chicken liver sausage were investigated. The optimal cooking conditions were determined: 80°C 30min. Under this condition, vitamin A loss rate was lowest. Different types of antioxidants vitamin C (ascorbic acid)EDTA-2Na (ethylenediaminetetraacetic acid disodium salt)BHT (2,4-di-tert.-butyl hydroxytoluene) were added to protect vitamin A. The results indicated the added antioxidants have obvious protective effects on vitamin A, and the protection effect of BHT is better than the others.

Abstract Vitamin C serves as a cofactor for Fe(II) and 2-oxoglutarate–dependent dioxygenases including TET family enzymes, which catalyze the oxidation of 5-methylcytosine into 5-hydroxymethylcytosine and further oxidize methylcytosines. Loss-of-function mutations in epigenetic regulators such as TET genes are prevalent in hematopoietic malignancies. Vitamin C deficiency is frequently observed in cancer patients. In this review, we discuss the role of vitamin C and TET proteins in cancer, with a focus on hematopoietic malignancies, T regulatory cells, and other immune system cells.

ABSTRACT Background Age-related loss of skeletal muscle mass contributes to poor outcomes including sarcopenia, physical disability, frailty, type 2 diabetes, and mortality. Vitamin C has physiological relevance to skeletal muscle and may protect it during aging, but few studies have investigated its importance in older populations. Objectives We aimed to investigate cross-sectional associations of dietary and plasma vitamin C with proxy measures of skeletal muscle mass in a large cohort of middle- and older-aged individuals.

Background: Periodontal disease is the leading cause of tooth loss worldwide. Current periodontal treatment is limited by its dependency on patients learning and maintaining good dental habits, and repeated visits to oral health physicians. Vitamin C’s role in collagen synthesis and immune function makes it important in wound healing and possibly periodontal healing. Therefore, if some patients are deficient, this may worsen patient outcomes. Methods: Patients were invited to participate following assessment and treatment at the Westmead Centre of Oral Health Periodontic Clinic, regardless of

Osteoarthritis (OA) is a strongly age-related joint disorder that is defined as a gradual loss of articular cartilage. Current concepts of the pathogenic mechanisms of OA suggest that there isa shift in the homeostatic balance between the destruction and synthesis of bone and cartilage,with a net progressive destruction of these tissues. Recent studies of the biology of chondrocytes show that these cells actively produce reactive oxygen species (ROS). ROS are capable of inducing apoptotic cell death in chondrocytes, but more important, they can result in the degradation of aggrecan and collage

Activated phagocytes produce the highly reactive oxidant hypochlorous acid (HOCl) via the myeloperoxidase-catalysed reaction of hydrogen peroxide with chloride ions. HOCl reacts readily with a number of susceptible targets on apolipoprotein B-100 of low-density lipoprotein (LDL), resulting in uncontrolled uptake of HOCl-modified LDL by macrophages. We have investigated the efects of vitamin C (ascorbate), an effective water-soluble antioxidant, on the HOCl- and chloramine-dependent modification of LDL.
