Assessing diet as a modifiable risk factor for pesticide exposure.

The effects of pesticides on the general population, largely as a result of dietary exposure, are unclear. Adopting an organic diet appears to be an obvious solution for reducing dietary pesticide exposure and this is supported by biomonitoring studies in children. However, results of research into the effects of organic diets on pesticide exposure are difficult to interpret in light of the many complexities. Therefore future studies must be carefully designed. While biomonitoring can account for differences in overall exposure it cannot necessarily attribute the source. Due diligence must be

Is a Good Sleep on Mosquito-Free Nights Worth the Risk of Lymphoma Associated with the Use of Household Insecticides? A Case-Control Study of Lymphoma Subtypes in Adults.

BackgroundThe evidence linking the use of household pesticides and the risk of lymphoma is scanty.MethodsWe explored the hypothesis in a population-based case-control study on lymphoma conducted in Sardinia, Italy, in 1998-2004, including 325 cases and 465 population controls and data on lifetime frequency, seasonality, and years of use of household insecticides and potential confounders. We calculated the risk of lymphoma (all subtypes) and its major subtypes associated with using household insecticides in three time windows (up to 1978, from 1979-2001, and 2002 onwards) with unconditional lo

Hesperidin Mitigates Cyclophosphamide-Induced Testicular Dysfunction via Altering the Hypothalamic Pituitary Gonadal Axis and Testicular Steroidogenesis, Inflammation, and Apoptosis in Male Rats.

Cyclophosphamide (CP) is a cytotoxic, cell cycle, non-specific, and antiproliferative drug. This study aimed to address the toxic effects of CP on male fertility and the possible ameliorative role of hesperidin (HSP). Thirty-two adult albino rats were randomly divided into four groups, namely, the negative control, HSP, CP-treated, and CP+HSP-treated groups. The CP-treated rats showed a significant reduction in the levels of serum LH, FSH, testosterone, prolactin, testicular glutathione peroxidase (GPx), and total antioxidant capacity (TAC) with an elevation in levels of malondialdehyde (MDA),
