Validation of a Modified QuEChERS Method for the Determination of Selected Organochlorine Compounds in Honey

Molecules, 2023
Honey is considered to be a health-promoting food product. Therefore, it is assumed that it should be free of contaminants. Although the use of organochlorine pesticides (OCPs) was banned a few decades ago in developed countries, persistent organic ...

Modeling of gene expression pattern alteration by p,p′-DDE and dieldrin in largemouth bass [PDF]

Marine Environmental Research, 2006
In this study, largemouth bass (LMB) were subchronically exposed to p,p'-DDE or dieldrin in their diet to evaluate the effect of exposure on expression of genes involved in reproduction and steroid homeostasis. Using real-time PCR, we detected a different gene expression pattern for each OCP, suggesting that they each affect LMB in a different way.

Palatal donor site wound healing following mucogingival surgery using amnion‐chorion membrane: A randomized controlled clinical trial

Journal of Periodontology, EarlyView.
Abstract Background Free soft tissue autografts (FSTA) harvested from a patient's palate are frequently associated with significant postoperative morbidity. Several wound dressings have been applied to the palatal donor site with the aim of reducing postoperative complications and improving wound healing.

Associations Between Cumulative Head Trauma and Self‐Reported Parkinsonism and Parkinson's Disease in Former Soccer Players

Movement Disorders, EarlyView.
Abstract Background Cumulative head trauma, encompassing repetitive head impacts (RHI) and traumatic brain injury (TBI), has been associated with later‐life neurodegenerative disease. Studies on parkinsonism/Parkinson's disease (PD) have evaluated RHI and TBI in isolation, yielding mixed results.

Accumulation of polychlorobiphenyl congeners and p,p′-DDE at environmental concentrations by corn and beans

Ecotoxicology and Environmental Safety, 1989
The uptake of polychlorinated biphenyl (PCB) congeners present at low concentrations in the environment was investigated in leaf composites of four crop species and final fruits at two sites. All four species preferentially accumulated the same eight congeners, although not in the same degree or rank. No bean species demonstrated a significant increase

Dumpsite Seabed Characterization of the San Pedro Basin, CA, From Autonomous Vehicle Observations

Journal of Field Robotics, EarlyView.
ABSTRACT A wide‐area seabed survey was conducted using autonomous underwater vehicles (AUVs) in a known dumpsite off the coast of Southern California that has been found to have widespread sediment contamination from the chemical dichlorodiphenyltrichloroethane (DDT).

Metabolite of the pesticide DDT and incident type 2 diabetes in urban India

Environment International, 2019
Background: Previous epidemiological studies, largely conducted in high-income countries and cross-sectional, have suggested a relatively strong association between exposure to dichlorodiphenyldichloroethylene (DDE), a metabolite of the pesticide ...

Oxidative Damage, Energy Imbalance, and Behavioral Disruptions in Girardia tigrina Exposed to Treated Sewage Effluents

Environmental Toxicology, EarlyView.
ABSTRACT This study assessed the ecotoxicological effects of treated sewage on the freshwater planarian Girardia tigrina, integrating biochemical, energetic, and behavioral biomarkers. Planarians were exposed for 48 h to different concentrations of treated sewage (12.5%, 25%, 50%, and 100%) and compared to controls using commercial water and water from
