ABSTRACT Background: To determine daily calcium, Vitamin D intake and serum biochemical findings of rickets in adolescent girls. Methods: A total of 414 healthy adolescent student girls aged 11-15 years were evaluated from various areas of Tehran, Iran with different socioeconomic status. A randomized, cross-sectional, prospective and descriptive study was undertaken for calculation of daily c...
Background: Exposure to particulate air pollutants is one of the major problems and crises in Tehran metropolis, Iran. Various studies have shown the effect of particulate matter of air contaminants as an increase in cardiovascular and oxidative stress. So, the purpose of this study was to examine the relationship of <2.5 micrometers and <10 micrometers microns particulate matter (PM2.5 and PM1...
On the 25th July, the European Food Safety Authority (EFSA) launched an open consultation on a draft assessment of consumer exposure to BPA performed by the EFSA’s Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel). This was the Authority’s first review of exposure to BPA since 2006 and the first to cover both dietary and non-dietary sources. Data from scienti...
Threshold concentrations associated with adverse effects of dietary exposure to methylmercury (MeHg) were derived from published results of laboratory studies on a variety of fish species. Adverse effects related to mortality were uncommon, whereas adverse effects related to growth occurred only at dietary MeHg concentrations exceeding 2.5 µg g(-1) wet weight. Adverse effects on behavior of fis...
Aflatoxicosis has repeatedly affected Kenyans, particularly in the eastern region, due to consumption of contaminated maize. However, save for the cases of acute toxicity, the levels of sub-lethal exposure have not been adequately assessed. It is believed that this type of exposure does exist even during the seasons when acute toxicity does not occur. This study, therefore, was designed to asse...
Insects have long been known to excrete toxins via the Malpighian (renal) tubules. In addition, exposure to natural or synthetic toxins is commonly associated with increases in the activity of detoxification enzymes such as the P450 monoxygenases (P450s) and the glutathione-S-transferases (GSTs). We examined the links between mechanisms for detoxification and excretion in adult Drosophila melan...
Herb Induced Liver Injury (HILI) is a condition in which there aggression to the liver tissue after exposure substances present many different medications, dietary supplements, herbs and xenobiotics.
The variation in dietary exposure to acrylamide (AA) has been studied through measurement of hemoglobin adduct levels from AA, as a measurement of internal dose, in a sample from the blood bank of the Malmö Diet and Cancer Cohort (n=28,098). The blood donors are well characterised with regard to their food habits, and 142 individuals were selected to obtain highest possible variation in the add...
BACKGROUND China has the world's largest tea plantation area in the world. To sustain high yields of the tea, multiple pesticides are used on tea crops to control pests. Organophosphorus (OP) pesticides are among the most widely used types of agricultural pesticides in China. As tea is a significant potential source of exposure to pesticide residues, the public concern has increased in relation...
OBJECTIVES This survey was designed to conduct the first nationwide dietary exposure assessment on hazardous substances including the intakes of functional food and herbal medicine. In this paper, we introduced the survey design and the results of the dietary exposure status and internal exposure levels of lead (Pb), cadmium (Cd), and mercury (Hg). METHODS We selected 4867 subjects of all age...
