Loperamide is an over-the-counter antidiarrheal with opioid-receptor agonist properties. Recommended over-the-counter doses (range = 2-8 mg daily) do not produce opioid effects in the central nervous system because of poor oral bioavailability and P-glycoprotein efflux* of the medication (1); recent reports suggest that large doses (50-300 mg) of loperamide produce euphoria, central nervous sys...

OBJECTIVES The purpose of this study was to describe differences in childhood pesticide exposures between counties on the Texas-Mexico border and nonborder counties. METHOD The authors reviewed all pesticide exposures among children younger than 6 years reported to the South Texas Poison Center during 1997 through 2000. RESULTS Nonborder counties had twice the reported exposure rate of bord...

CO2 electroreduction powered by renewable energy is an attractive strategy to close the carbon cycle. Among possible reduction products, CO of particular interest due its large industrial applications. Transition metals in Pt group are able electrochemically reduce CO, but suffer from surface poisoning, which causes a quick deactivation and overall sluggish kinetics. Here, we show that introduc...

The use of steel-work off-gases as CO2 source for methanol production is a promising strategy the decarbonization steel industry. In this work, we show that typical impurities, namely S, N, Na, Ca and Fe, reduce activity commercial CuO/ZnO/Al2O3 catalyst by blocking part Cu active sites. extent loss proportional to poison-induced decrease in exposed surface area, suggesting poisons do not modif...

Household waste is originating from kitchens, bathrooms, laundry, former household industrial and human waste. generated every day the amount too much to match population has potential pollute poison environment. Management of in order reduce impact on environment public health. The method used this study a batch system through coagulation-flocculation process. first step by adding chlorine lim...

nuated blood, with the altered character of its elements; the dilatation of the pupils; the foaming at the mouth; and the general lethargy, followed by convulsions and death. J This is not a poisonous snake. It is known also, in Bengal, as Betaehra. The term lineatus has been suggested by Dr. Sircar, because of the resemblance of the snake to the one described under that namely Russel at page 3...

Urushiols are the allergenic components of Toxicodendron radicans (poison ivy) as well as other Toxicodendron species. They are alk-(en)-yl catechol derivatives with a 15- or 17-carbon side chain having different degrees of unsaturation. Although several methods have been developed for analysis of urushiols in plant tissues, the in situ localization of the different urushiol congeners has not b...

Strategies for the control of vertebrate pest are identified using mathematical models of poisoning. The models integrate aspects of foraging ecology and toxicology in a probabilistic framework. The structure, assumptions and control implications of the models are presented. Variables (control parameters) influencing the probability that a pest animal dies in a poison programme are identified a...

Poison message failure propagation is a mechanism that has been responsible for large scale failures in both telecommunications and IP networks: Some or all of the network elements have a software or protocol ‘bug’ that is activated on receipt of a certain network control/management message (the poison message). This activated ‘bug’ will cause the node to fail with some probability. If the netw...
