1. Quality analysis of galvanized pipes applied to natural gas installations in civil construction
ABSTRACT Some natural gas distributors for residential and commercial buildings in Brazil use galvanized steel tubes and fittings manufactured by the hot-dip zinc process that are supported by the specifications contained in the Brazilian Standards. Zinc coating is one of the most widely used methods to provide protection against corrosion. It is therefore e

2. Preliminary molecular characterization of a proinflammatory and nociceptive molecule from the Echinometra lucunter spines extracts
Abstract Background Sea urchins are animals commonly found on the Brazilian shoreline, being Echinometra lucunter the most abundant species. Accidents caused by E. lucunter have been reported as one of the most frequent in Brazil, and are characterized by intense pain and inflammation, consequence of spine puncture in the skin. In order to characterize suc

3. PCDD/Fs and PCBs in Soils: a Study of Case in the City of Belo Horizonte-MG
Dioxins (polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) and polychlorinated biphenyls (PCBs)) are substances that represent a global concern due to their ubiquitous presence and toxicity. Industrial processes and other human activities as well as uncontrollable accidents are the main sources that release these pollutants into t

4. Cardiorespiratory alterations in rodents experimentally envenomed with Hadruroides lunatus scorpion venom
Abstract Background Hadruroides lunatus is the most abundant scorpion species in the Peruvian central coast, where most of the accidents involving humans are registered. In spite of its prevalence, there are only very few studies on H. lunatus envenomation. The aim of the present study was to analyze the cardiorespiratory alterations caused by H. lunatus en

5. Inhibitory effects of Swietenia macrophylla on myotoxic phospholipases A2
Activity-guided fractionation of an ethanol-soluble extract of the leaves of Swietenia macrophylla King, Meliaceae, led to several fractions. As a result, sample Sm13-16, 23 had the most promising activity against phospholipases A2 (PLA2), Asp49 and Lys49 types. This fraction inhibited PLA2 activity of the Asp49 PLA2, when aggregated substrate was used. On t

6. Scorpionism in Central America, with special reference to the case of Panama
Scorpionism in the Americas occurs mainly in Mexico, northern South America and southeast Brazil. This article reviews the local scorpion fauna, available health statistics, and the literature to assess scorpionism in Central America. Notwithstanding its high toxicity in Mexico, most scorpion sting cases in Guatemala, Belize, El Salvador, Nicaragua, and Cost

7. General characterization of venom from the Moroccan snakes Macrovipera mauritanica and Cerastes cerastes
Ophidian envenomation accidents constitute a serious public health problem in many countries around the globe. Over 5 million such accident cases occur each year causing more than 100,000 deaths. In Africa, more than 20,000 deaths per year are registered while 400,000 envenomation victims retain severe and permanent functional sequelae. In Morocco, snakebite

8. Estudo das atividades das cabenegrinas A-I e A-II frente aos efeitos hematolÃgicos e histolÃgicos induzidos pelo veneno total e fraÃÃes da serpente Bothrops neuwiedi em camundongos Swiss. / Study of the activities of cabenegrinas A-I and A-II compared to the histological and hematological effects induced by the venom and fractions of the snake Bothrops neuwiedi in Swiss mice.
The venom of the Bothrops neuwiedi provokes an action mainly of the hemorrhagic, proteolytic and coagulant type. When inoculated, the venom cause primarily a local action, and secondarily a systemic action. The systemic effects of poisoning include changes in various systems such as hematological, cardiovascular, liver, urinary, respiratory, immune, digestiv

9. Clinical and electrocardiographic evaluation during experimental toad poisoning in dogs
Accidents involving toad poisoning are frequent and dogs are the most common victims; they become poisoned by biting or ingesting a toad. When released in the organism, the venom is absorbed by both the oral mucosa and the digestive tract, initiating its toxic action. The aim of this work was to evaluate the clinical and electrocardiographic aspects of dogs

10. ESTUDO DOS EFEITOS RENAIS E VASCULARES DO VENENO DA SERPENTE Crotalus durissus cumanensis E CROTOXINA / RENAL AND VASCULAR EFFECTS FROM Crotalus durissus cumanensis VENOM AND CROTOXIN
Ophidian accidents involving species of the genus Crotalus, are usually serious and frequently fatal due to the frequency of acute renal failure. Unfortunately, there have been few studies of the toxinologic effects of Crotalus durissus cumanensis venom. The renal effects of the venom used in this study were observed by perfusion of isolated kidneys. Infusio
