The present review reports the research carried out during last 9 years on biosensors based on cholinesterase inhibition for nerve agents, organophosphorus and carbammic insecticides, and aflatoxin B1 detection. Relative applications in environmental and food areas are also reported. Special attention is paid to the optimization of parameters such as enzyme immobilization, substrate concentrati...

Organophosphorus pesticides have been used in some cases for suicidal attempts. Such poison can affect plasma cholinesterase activity. The case was a 47-year-old man hospitalized due to suicide attempt with swallowing agricultural poison. The patient, diagnosed with major depressive disorder (MDD), underwent treatment with electroconvulsive therapy (ECT). At the first ECT session, the patient d...

Self-poisoning with organophosphate pesticides is a major health problem world-wide. Through the inhibition of acetylcholinesterase, organophosphorus poisoning is characterised by the clinical picture of acute cholinergic crisis. Other manifestations are the intermediate neurotoxic syndrome and delayed polyneuropathy. In the Western world, the occurrence of organophosphorus poisoning is less pr...

A decision support system (DSS) for potato and tom ato late blight m anagem ent has been developed to provide disease m anagem ent recom m endations. The system is com prised of two disease-forecasting tools as well as a simulator. Results from simulation and field experim ents w ith the system have shown that the DSS schedules on moderately susceptible crops did not achieve sufficient disease ...

Mutualistic interactions with fungal endophytes and dinitrogen-fixing bacteria are known to exert key biological influences on the host plant. The influence of a fungal endophyte alkaloid on the toxicity of a plant has been documented in Oxytropis sericea. Oxytropis sericea is a perennial legume responsible for livestock poisoning in western North America. Livestock poisoning is attributed to t...

Banana is the fourth most important staple food in the world, behind rice, wheat, and maize, with more than 100 million tons produced annually [1]. Although the majority of bananas produced are consumed locally, banana export is a multi-billion–dollar business [2]. Bananas are grown in more than 100 countries worldwide, largely in developing countries in tropical regions of Africa, Asia, and La...

the aim of this study was to determine the environmental risk of pesticide a.i. applied to control insects and fungus in cereal farming in sanliurfa, turkey. in 2013, 8 active ingredients (a.i.) in cereal farming were applied for insect and fungus control in sanliurfa, turkey. these a.i. were alpha-cypermethrin(ec), chlorpyrifos(ec;wp), difenoconazole(ec), indoxacarb(wg), lambda-cyhalothrin(ec)...

INTRODUCTION Acetylcholinesterase inhibition by organophosphorus pesticides or organophosphate nerve agents can cause acute parasympathetic system dysfunction, muscle weakness, seizures, coma, and respiratory failure. Prognosis depends on the dose and relative toxicity of the specific compound, as well as pharmacokinetic factors. METHODS AND OUTCOMES We conducted a systematic review and aimed...
