Conventional hydrostatic barium reduction or pneumatic reduction of intussusception is associated with considerable ionizing radiation. The aim of this study was to evaluate ultrasound-guided hydrostatic reduction for childhood intussusception using water enema. A total of 76 children who diagnosed as having intussusception were referred to Doctor Sheikh Children Hospital in Mashhad (northeast ...

BACKGROUND Natural insecticides against the vector mosquito Aedes aegypti have been the object of research due to their high level of eco-safety. The water-soluble Moringa oleifera lectin (WSMoL) is a larvicidal agent against A. aegypti. This work reports the effects of WSMoL on oviposition and egg hatching of A. aegypti. METHODOLOGY/PRINCIPAL FINDINGS WSMoL crude preparations (seed extract a...

BACKGROUND Inorganic arsenic (iAs) is a ubiquitous element present in the groundwater worldwide. Cardiovascular effects related to iAs exposure have been studied extensively in adult populations. Few epidemiological studies have been focused on iAs exposure-related cardiovascular disease in children. OBJECTIVE In this study we investigated the association between iAs exposure, blood pressure ...

A demonstration plant consisted of granular activated carbon (GAC) and ozone/GAC process was operated using filtered water of a conventional water treatment plant as influent to study feasibility of introducing advanced water treatment. Natural organic matter (NOM) from process waters at the demonstration plant was isolated into hydrophobic and hydrophilic fractions by physicochemical fractiona...

Textile wastewater contains substantial pollution loads in terms of Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Total Suspended Solids (TSS), Total Dissolved Solids (TDS) and heavy metals. Phytoremediation used for removing heavy metals and other pollutants by aquatic macrophytes treatment systems (AMATS) is well established environmental protective technique. A lab scale stud...

The removal of dissolved organic carbon (DOC) is a key factor in the control disinfection by-product (DBP) formation drinking water. Ion exchange process deals with naturally negatively charged matter. A fluidized bed column test has been chosen to parallel efficiency 4 different anionic resins (Purolite PPA860S, Dowex TAN-1, Amberlite IRA-958 and IRA-410) terms DOC fraction related DBP reducti...
