A Comparative Study of Iodized Salt Programs: Shanghai and Switzerland.
Abstract Both Shanghai and Switzerland are developed regions with long-standing salt iodization programs and periodic monitoring. However, the two regions have their own approach to the implementation of the iodized salt policy. In Shanghai, monitoring was carried out every few years, using probability-proportional-to-size sampling technique to select 30 sampling units. Each unit consisted of more than 12 pregnant women and one randomly selected primary school. Urine samples were then taken from the chosen pregnant women and randomly recruited students of that school for iodine test. Data of Switzerland used in th...

Moringa oleifera Leaves Extract Protects Titanium Dioxide Nanoparticles-Induced Nephrotoxicity via Nrf2/HO-1 Signaling and Amelioration of Oxidative Stress.
In conclusion, MO can inhibit nephrotoxicity by suppressing oxidative stress and inflammation. These effects are suggested to be mediated by activating Nrf2/HO-1.The biochemical analysis and histopathological finding reinforced these results. These data support the antioxidant properties' nutraceutical role of MO against TiO2NPs-induced toxicity.

Health Risk Assessment and Urinary Excretion of Children Exposed to Arsenic through Drinking Water and Soils in Sonora, Mexico.
ntenegro MM Abstract Environmental arsenic exposure is associated with increased risk of non-cancerous chronic diseases and a variety of cancers in humans. The aims of this study were to carry out for the first time a health risk assessment for two common arsenic exposure routes (drinking water and soil ingestion) in children living in the most important agricultural areas in the Yaqui and Mayo valleys in Sonora, Mexico. Drinking water sampling was conducted in the wells of 57 towns. A cross-sectional study was done in 306 children from 13 villages in the valleys. First morning void urine samples were analyzed for...

Protective Effect of Ganoderma Triterpenoids on Cadmium-Induced Testicular Toxicity in Chickens.
Abstract Studies have shown that cadmium can cause chicken testicular damage, but a protective effect of Ganoderma triterpenoids on cadmium-induced testicular damage in chickens has not yet been reported. The present study was designed to research the protective effect of Ganoderma triterpenoids on cadmium-induced testicular damage in chicken. Eighty healthy 7-day-old Hyline egg laying chickens were randomly divided into four groups with 20 in each group. The control group was fed with normal full-fodder, the model group was fed with normal full-fodder with 140 mg/kg of CdCl2, the Ganoderma triterpenoid treat...

Liver Proteome of Mice with Distinct Genetic Susceptibilities to Fluorosis Treated with Different Concentrations of F in the Drinking Water.
This study evaluated the effects of F on the liver proteome of mice susceptible (A/J) or resistant (129P3/J) to the effects of F. Weanling male A/J (n = 12) and 129P3/J (n = 12) mice were housed in pairs and assigned to two groups given low-F food and drinking water containing 15 or 50 ppm F for 6 weeks. Liver proteome profiles were examined using nano-LC-ESI-MS/MS. Difference in expression among the groups was determined using the PLGS software. Treatment with the lower F concentration provoked more pronounced alterations in fold change in liver proteins in comparison to the treatment wit...

Chronic Cadmium Exposure Accelerates the Development of Atherosclerosis and Induces Vascular Dysfunction in the Aorta of ApoE-/- Mice.
Abstract Cadmium exposure is related to cardiovascular diseases, including hypertension, atherosclerosis, increased oxidative stress, endothelial dysfunction, and specific biochemical changes induced by this metal. Thus, we aimed to investigate whether cadmium exposure induces endothelial dysfunction, accelerates atherosclerotic plaque formation in the aorta, and enhances oxidative stress in apolipoprotein E knockout (ApoE-/-) mice. Experiments were performed in 14-week-old male wild-type and ApoE-/- mice. ApoE-/- mice received cadmium (CdCl2 100 mg/L in drinking water for 28 days) or vehicle (distilled ...

Tissue Trace Elements and Lipid Peroxidation in Breeding Female Bank Voles Myodes glareolus.
Abstract Recent studies have demonstrated that reproduction reduces oxidative damage in various tissues of small mammal females. The present work was designed to determine whether the reduction of oxidative stress in reproductive bank vole females was associated with changes in tissue trace elements (iron, copper, zinc) that play an essential role in the production of reactive oxygen species. Lipid peroxidation (a marker of oxidative stress) and iron concentration in liver, kidneys, and skeletal muscles of reproducing bank vole females that weaned one litter were significantly lower than in non-reproducing females...

Analysis of the Relationship Between Hemorheologic Parameters, Aluminum, Manganese, and Selenium in Smokers.
In conclusion, increased Al, Mn, and hemorheological parameters and decreased Se and ODI45 might result from inflammatory response in defense mechanism in smokers without diagnosis of COPD. Our results point out that serum Al, Mn, and Se with hemorheological parameters may be beneficial markers of tissue oxygenation and defense mechanism before the clinic onset of COPD in smokers.
