BACKGROUND: Vitamin C is one of the key antioxidant vitamins which is abundant in the extracellular fluid lining the lung and low vitamin C intake has been associated with pulmonary dysfunction. OBJECTIVES: To evaluate the evidence for the efficacy of vitamin C in the results of asthma.
SEARCH STRATEGY: The Cochrane Airways Review Group asthma register was searched and bibliographies of studies identified were also checked for further trials.
Background: Exposure to heavy metals may cause kidney damage. The population living near the Avonmouth zinc smelter has been exposed to cadmium and other heavy metals for many decades.
Objectives: We aimed to assess Cd body burden and early signs of kidney damage in the Avonmouth population.
Methods: We used dispersion modeling to assess exposure to Cd.
A total of 216 kg of cucumber samples, representing three different types of farming production [e.g., conventional (C), greenhouse (G) and organic (O)], were collected from different locations in Giza governorate (Egypt), and subjected to pesticide residue and heavy metal analyses. Residues of some organochlorine pesticides (OCPs), such as hexachlorobenzene (HCB), heptachlor, aldrin, endrin, dieldrin and o,p′-DDT,
Background: There has been little interest in the role of nutrition in the prevention of amyotrophic lateral sclerosis (ALS). We investigated the relationship between dietary intake of vegetables, fruit, and antioxidants and the risk of ALS in Japan.
Methods: Between 2000 and 2004, we recruited 153 ALS patients aged 18-81 years with disease duration of 3 years within the study period in accordance with El Escorial World Federation of Neurology criteria.
Background: Virgin olive oils are richer in phenolic content than refined olive oil. Small, randomized, crossover, controlled trials on the antioxidant effect of phenolic compounds from real-life daily doses of olive oil in humans have yielded conflicting results. Little information is available on the effect of the phenolic compounds of olive oil on plasma lipid levels.
Background The role of circulating levels of total homocysteine tHcy in the development of coronary heart disease (CHD) is still under debate. One reason for conflicting results between previous studies on homocysteine and heart diseases could be consequence of different interactions between homocysteine and genes in different study populations. Many genetic factors play a role in folate-homocysteine metabolism,
Background and Purpose— Limited evidence was available on the metabolic syndrome and risk of cardiovascular disease in Asia. The purpose of this study is to examine the association of the metabolic syndrome and risk of ischemic cardiovascular disease in Japanese men and women.
Methods— We conducted an 18-year prospective study of 9087 Japanese people aged 40 to 69 years (3595 men and 5492 women),
Objective— Subjects with family history for coronary heart disease (CHD) may be more susceptible to the adverse effects of risk factors than subjects without family history. We investigated the occurrence of subclinical atherosclerosis in young adults with family history of CHD and tested the hypothesis that their arteries are more vulnerable to the proatherogenic effects of metabolic risk factors.
