background: the german cockroach, blattella germanica l. (dictyoptera: blattellidae), has become resistant to many insecticides due to control failures in hospital and student dormitory settings of southern iran. objective: this study was thus designed to detect and monitor carbamate resistance in two strains of german cockroach using lethal dose bioassay methods. methods: wild dormitory (d) an...

We discuss a case of a 17-year-old white male who intentionally ingested a tick and flea insecticide and was admitted to the emergency room unconscious, with signs and symptoms of cholinergic toxicity. Capillary gas chromatography and electron-impact mass fragmentographic analysis of the patient's urine and serum demonstrated the presence of poly-ethylene glycol and propoxur (o-isopropoxyphenyl...

BACKGROUND Highly hazardous organophosphorus (OP) insecticides are responsible for most pesticide poisoning deaths. As they are removed from agricultural practice, they are often replaced by carbamate insecticides of perceived lower toxicity. However, relatively little is known about poisoning with these insecticides. METHODS We prospectively studied 1288 patients self-poisoned with carbamate...

CONTEXT Carbamate insecticides are widely used in commercial agriculture and home gardening. A serious side effect of organophosphate and carbamate intoxication is the development of acute pancreatitis. CASE REPORT A 36-year-old Caucasian woman was admitted to our hospital with cholinergic crisis and pancreatitis soon after the ingestion of a carbamate insecticide (carbofuran). An abdominal C...

Children's Exposure to Pesticides Exposures of Farmworkers and Their Families Potential Health Effects of Exposure to OP Pesticides Effects of Acute Exposure to OP and Carbamate Pesticides in Children Long-Term Sequelae of Acute Exposure to OP and Carbamate Pesticides in Adults Effects of Chronic Exposure to OP and Carbamate Pesticides in Adults Animal Evidence for Neurodevelopmental Effects of...

he majority of carbon dioxide in blood is trans-Tported in the form of bicarbonate, and only relatively small amounts exist as dissolved Con or carbamate. The latter compound is formed by the combination of free carbon dioxide with uncharged amino groups of hemoglobin. Hb=NH,+=Hb-NH2 + H + The role of carbamate in carbon dioxide exchange is more important than would be expected from its small c...

A reversible amine-carbamate approach has been developed to reduce the use of antisolvents such as water in coagulation biopolymers from ionic liquid (IL) solution and thus improve economy IL recycle. Cellulose chitin were recovered 1-ethyl-3-methylimidazolium acetate ([C 2 mim][OAc]) by introducing miscible amines triethanolamine (TEA), ethylenediamine (EDA), or butylamine (BA) bubbling CO at ...

-A tumour initiating dose of ethyl carbamate was administered to mice by subcutaneous injection together with a dose of one of the homologous esters or an ethyl N-alkyl derivative. The homologues used were the methyl, n-propyl and n-butyl esters, and the derivatives were the N-methyl, N-ethyl and N-n-propyl ethyl esters. The mice were then given promoting treatment with croton oil for 28 weeks....
