标题:Development Of An Immunoassay For The Pyrethroid Insecticide Esfenvalerate
摘要:A Competitive Enzyme-Linked Immunosorbent Assay Was Developed For The Detection Of The Pyrethroid Insecticide Esfenvalerate. Two Haptens Containing Amine Or Propanoic Acid Groups On The Terminal Aromatic Ring Of The Fenvalerate Molecule Were Synthesized And Coupled To Carrier Proteins As Immunogens. Five Antisera Were Produced And Screened Against Eight Different Coating Antigens. The Assay That Had The Least Interference And Was The Most Sensitive For Esfenvalerate Was Optimized And Characterized. The I-50 For Esfenvalerate Was 30 +/-6.2 Mu G/l,And The Lower Detection Limit (Ldl) Was 3.0 +/-1.8 Mu G/l. The Assay Was Very Selective. Other Pyrethroid Analogues And Esfenvalerate Metabolites Tested Did Not Cross-React Significantly In This Assay. To Increase The Sensitivity Of The Overall Method,A C-18 Sorbent-Based. Solid-Phase Extraction (Spe) Was Used For Water Matrix. With This Spe Step,The Ldl Of The Overall Method For Esfenvalerate Was 0.1 Mu G/l In Water Samples.

摘要:Systems and methods for treating symptoms of an inflammatory gastrointestinal disease in a patient with transcutaneous stimulation of a peripheral nerve are disclosed. The method can include any number of positioning a first peripheral nerve effector on the patient's skin to stimulate the peripheral nerve of the patient, delivering a first electrical nerve stimulation signal transcutaneously to the peripheral nerve through the first peripheral nerve effector, and modifying at least one brain or spinal cord autonomic feedback loop relating to release of neurotransmitters from the autonomic nervous system that modulate synthesis of inflammatory biomarkers and reduce inflammation relating to the inflammatory gastrointestinal disease.
