The Effects of Lead Acetate on Host Susceptibility to Trypanosoma Cruzi
… and their ability to act as immunosuppressants. Lead is of particular interest because it is widespread in places such as soil, food, water, batteries, paints, and plastics. Studies have shown lead exposure during bacterial and viral infection causes decreases in antibody production, T cell …

The Effect of Lead Acetate on the Susceptibility of C3HeB/FeJ Mice Infected with the Parasite Trypanosoma Cruzi
<p>Lead has been mined by man for centuries with evidence of its use dating back 6000 years. Chronic exposure to lead can result in encephalopathy, anemia, and nephropathy. Today, cases of lead poisoning are uncommon; however, lead continues to be incorporated into the body through subclinical …

Neurotoxic effects of malathion and lead acetate on the blood-brain barrier: Disruptive effects caused by different mechanisms examined with an in vitro blood-brain barrier system
… the world, especially as insecticides. Lead particles can accumulate in soil and from there leach into our water supplies. Interaction with the environment offers opportunities for multiple exposures to combinations of different toxicants (such as lead and malathion). Thus, it is …

Pengaruh pemberian ekstrak etanol jintan hitam (Nigella sativa) terhadap integritas membran spermatozoa dan kadar malondialdehyde (MDA) epididimis mencit yang dipapar timbal (Pb) esetat peroral
… mencit yang dipapar Pb peroral. ENGLISH: Lead acetate is one of the sources of ROS can lead to lipid peroxidation and increased levels of malondialdehyde (MDA) induced by oxidative stress. One caused by oxidative stress is the disruption of the process of maturation of spermatozoa in the …

Effects of low level lead and cadmium on reproduction in Peromyscus leucopus and a study of lead concentration in small mammals from old orchards
Lead and cadmium frequently occur together as contaminants in polluted environments such as roadsides, urban areas, mines, and smelters. Few studies have been conducted to examine the possible interactive effects these metals may have on reproduction of wild species. The first part of this study …

The effect of soil parameters on the bioavailability and retention of lead in rats
… (lime and phosphate) to the retention of lead in soil fed to rats. This study also related the amount of lead that can be extracted from in situ contaminated soils from a secondary smelter site to both soil properties and to the tissue lead concentrations in rats. In a six week feeding …

Liver hydroxymethylbilane synthetase (EC 4.3.1.2) : an environmental and toxilogical kinetic study. The Effect of experimental design and circumstance on three common linearization methods used in determining the Michaelis-Menten kinetic constants
… and showed definite response during dosings with lead acetate and trichlorobenzene as well as benzene, carvone, benzanthracene, phenobarbital and lindane. The rat liver enzyme proved sensitive to a large spectrum of meavy metal ions and indicated the possible existence and cytsteine, histidine and …

The Absorption of the Lead Cation from the Intestine of the Rat
The gastrointestinal absorption of lead was studied using two techniques, one in vitro, the other in vivo. The in vitro technique used was that of everted intestinal sacs. The in vivo method was a whole body study where rats were dosed intragastrically with a known dose of radiolabelled lead …

Preparation and characterization of doped lead zirconate titanate Pb(Zr<sub>x</sub>Ti<sub>1-x</sub>)O₃ films
… making the undoped PZT films were derived from lead acetate, zirconium n-propoxide, and titanium iso-propoxide. In addition, lanthanum acetylacetonate, neodymium acetate, and niobium ethoxide were introduced into the precursor solution to accomplish doping of the corresponding elements. Both …

Microglial dysfunction as an early susceptibility to Alzheimer's disease: the exacerbating role of developmental toxicity
… to AD. Following postnatal exposure to lead acetate (Pb) from postnatal day (PND) 5-15, earlier and more severe amyloid accumulation was observed in the hippocampus concomitant to reduced microglial activation (densitometric Iba1+, CD45lo/CD11b+ characterization) in females compared to …

Mechanisms governing the abatement of metal emissions from waste incineration.
… with a surrogate metal containing waste (usually lead acetate). When sorbent is not introduced, lead vaporized in the flame ultimately forms a unimodal particle size distribution centered at approximately 0.1 μm., often referred to as fume. The injection of sorbent prevents the formation of this …

Preparation and characterization of lead lanthanum titanate thin films by metalorganic decomposition
… attracted a world wide attention. Cubic Lead Lanthanum Titanate (PLT) is one of the prime candidates in this respect and its structure and properties in the thin film form were investigated in the present study, for potential application in the ULSI DRAMs. Thin films of Lead Lanthanum …

Synthesis and characterisation of CdS and PbS nanoparticles in an imidazolium based ionic liquid
… used as single source precursor whereas cadmium acetate and dodecanethiol were used as dual source molecular precursors in the presence of 1-ethyl-3-methylimidazolium methanesulfonate ionic liquid. XRD studies confirmed the formation of cubic and hexagonal phases for low and high temperatures …
