although this practice is not effective. Snails and slugs withdrew from produce after the molluscicide was applied to surrounding vegetation, but returned after several days. We purchased a lettuce head that had been reportedly treated with molluscicides at the Coronation Market and found a small slug inside. The role of produce in transmitting A. cantonensis is still unclear; humans may become...

Atrazine has been identified in at least 20 of the 1,636 hazardous waste sites that have been proposed for inclusion on the EPA National Priorities List (NPL) (HazDat 2003). However, the number of sites evaluated for atrazine is not known. The frequency for these sites within the United States can be seen in Figure 6-1. Of these sites, all 20 are located within the United States and none are lo...

We investigate the performance of robust estimates of multivariate location under nonstandard data contamination models such as componentwise outliers (i.e., contamination in each variable is independent from the other variables). This model brings up a possible new source of statistical error that we call “propagation of outliers.” This source of error is unusual in the sense that it is genera...

Aim: To discuss about the specific characteristics of intestinal parasitic infection that contributes to formation stunting.
 Discussion: Intestinal parasites (IPI) are one global utmost health dilemmas, because they put certain vulnerable member population, e.g., children, in danger. Global prevalence rate IPI varied from 30-60%, especially developing countries located within region tropi...

A method is described for direct analysis of lead in blood utilizing the carbon rod atomizer. Aliquots of whole blood are analyzed without pre-treatment. Resuits are comparable to those for a similar non-flame technique in which whole blood samples were prediluted with “Triton X-100.” The small sample volumes required and the minimal sample preparation further diminish the possibility of spurio...

Hepatitis a general term which refers to inflammation of the liver. It may result from various causes, both infectious ( viral, bacterial, fungal, and parasitic) noninfectious (alcohol, drugs, autoimmune diseases, metabolic diseases). The hepatitis B X protein (HBx) plays role in epigenetic regulation HBV replication. Real-time PCR has catalysed wider acceptance because it is more rapid, sensit...

Hydatid cystic disease is a parasitic infestation caused by Echinococcus granulosus and commonly manifests as hepatic and pulmonary cysts. When feasible, based on cyst size and location, surgical resection is potentially curative. Post-surgical recurrence of disease is encountered in up to 25% of patients. Secondary peritoneal contamination is a recognized complication in 5-10% of cases. Dissem...
