BACKGROUND Intravenous (IV) iron is widely prescribed for patients on haemodialysis, to replace iron losses during treatment. It releases labile iron, which can induce oxidation of vitamin C and trigger oxidant damage. We examined the stability of vitamin C in the presence of IV iron compounds. We further examined in the ability of vitamin C to release iron from these compounds. METHODS Vitam...

The source and quantity of nutrients available to plants can affect the quality of leafy herbs. A study was conducted to compare quality of Cosmos caudatus in response to rates of organic and mineral-based fertilizers. Organic based fertilizer GOBI (8% N:8% P₂O₅:8% K₂O) and inorganic fertilizer (15% N, 15% P₂O₅, 15% K₂O) were evaluated based on N element rates at 0, 30, 60, 90, 120 kg h⁻¹. Appl...

To determine whether labeled antibodies against oxidized LDL (OxLDL) offer advantages for quantifying atherosclerosis, we compared in vivo aortic uptake of (125)I-labeled MDA2, a monoclonal antibody against malondialdehyde-lysine epitopes), atherosclerotic surface area, and aortic weight in Watanabe heritable hyperlipidemic and New Zealand White rabbits and in low density lipoprotein receptor-d...

Belowground interactions between plant roots, arbuscular mycorrhizal fungi (AMFs), and growth-promoting rhizobacteria (PGPR) can improve growth yield under abiotic stress conditions. A pot factorial experiment based on completely randomized design with three replications was conducted to investigate the effects of AMFs (without inoculation as control, Funneliformis mosseae intraradices) PGPRs c...

this investigation determined that vitamin c intake of c.w. was higher than o.p. , s. c. and c. statistically, there was a significant difference between c.w. and c. blood ascorbic acid levels of o.p. and s.c. were lower than c.w. and c. , a significant difference was observed. urinary vitamin c in all groups was lower than controls and this indicates that even though vitamin c intake was high,...

Vitamin C (L-AA, ascorbic acid) has major functions in oxidative stress defense (e.g. ozone, pathogens, wounding, etc.) because of its antioxidant properties, and this leads to improved fruit quality, storage and increased resistance to postharvest storage diseases. It also protects humans from various important diseases. Fruit is the best food source of vitamin C, but while apple is the most h...

The effect of the application of 1-methylcyclopropene (1-MCP) and wax emulsions, alone or combined, on composition analysis, vitamin C, polyphenols, and antioxidant capacity of soursop was evaluated. Fruits were stored as follows: at 25 °C (control), and at 16 °C: fruits sprayed with candelilla or flava emulsions, fruits treated with 1500 nL/L of 1-MCP (20 °C, 12 h), and fruits treated with 1-M...

Research has been on-going on many plant materials, especially those discarded as waste, to exploit their nutritional and antinutritional properties. This is as a result of the United Nations’ millennium development goal to eradicate extreme poverty and hunger. Avocado (Persea americana Mill) seeds are often discarded after taking the pulp of the fruit. This study is aimed at evaluating the eff...

Introduction.?It is generally recognized that human beings, monkeys and guinea-pigs do not synthesize vitamin C in their body. The difference in the time of onset of the symptoms ?f vitamin C deficiency were attributed to differences in age, sex and locality. The great extent to which pregnant women could tolerate vitamin C deficiency could not be explained. It has, however, been suggested that...
