[1] Jupiter has a large magnetosphere that episodically precipitates large amounts of energy into the polar atmosphere, giving rise to intense auroras [Clarke et al., 1996; Grodent et al., 2000]. An important consequence of this energy influx is the production of a dark haze [Pryor and Hord, 1991], the formation mechanism of which was hitherto poorly known. Recent observations of benzene on Jup...
Human plasma kallikrein was prepared by proteolytic activation of prekallikrein with beta-Factor XIIa (Mr = 28,000). Two forms of kallikrein were generated that were each composed of two disulfide-linked polypeptide chains: a heavy chain of apparent Mr = 43,000 and a light chain of apparent Mr = either 36,000 or 33,000. Following reduction and alkylation, the heavy and light chains of kallikrei...
tire manufacturing industry has a history of more than half a century in iran, where 14 thousand workers are employed. the old and semi-automated processes equipment, backward technology, and raw materials impurity lead to significant exposures to occupational carcinogens such as benzene. this study was to assessment of benzene exposures and evaluation the resulting cancer risk in two tire-manu...
Produced water is the largest waste discharge from the production phase of oil and gas wells. Produced water is a mixture of reservoir formation water and production chemicals from the separation process. This creates a chemical mixture that has several components of toxic concern, ranging from heavy metals to soluble hydrocarbons. Analysis of potential environmental effects from produced water...
Two lipophilic methotrexate analogues have been synthesized and evaluated for cytotoxicity against KATO III and HT-29 human colon cancer cells. Both analogues contained a C16-alkyl chain attached to the gamma-carboxylic acid and one of the analogues had an additional benzyl group attached to the alpha-carboxylic acid. The cytotoxicity of the gamma-alkylated compound towards KATO III (IC(50) = 5...
The current study aimed to examine the overall feasibility of the use of copper oxide nanoparticles (CuO-NPs) as a catalyst in ozonation process for the removal of benzene from aqueous solutions under experimental conditions. This experimental study was conducted on a laboratory scale reactor in a semi-batch mode. The effect of critical operating parameters such factors as pH, concentration of ...
Abstract Background: To establish a method for determination of in-cabin benzene and evaluate the occupational exposure, a cross-sectional study was conducted. Methods: In this descriptive study, 30 taxi-cabs were selected and the concentrations of benzene was measured in stopping and driving conditions using solid phase microinstruction (SPME) method. Results: The overall average conc...
Fusion of human peripheral blood lymphocytes, not forming detectable immunoglobulins, with mouse myeloma cells (TEPC-15), secreting mouse immunoglobulin A with known antibody activity, yielded a somatic cell hybrid clone that secreted both human and mouse immunoglobulins. Analysis by sodium dodecyl sulfate-polyacrylamide gel electrophoresis indicated that human gamma, alpha, and light chains, a...
A mouse monoclonal antibody OKT3, of IgG2a isotype, was isolated from hybridoma culture fluid. Sugar analysis showed the presence of sialic acid, galactose, mannose, fucose, and N-acetylglucosamine, i.e. sugars typical for N-glycosidically linked carbohydrate chains. The absence of N-acetylgalactosamine revealed that O-glycosidically linked carbohydrates were not present. The purified antibody ...
This study reports a rapid assay to distinguish depurination from other forms of alkaline-labile lesions induced in DNA by alkylating agents. Covalently closed circular duplex PM2 DNA was treated with various alkylating agents such as A/-methyl-Wnitrosourea, dimethyl sulfate, methyl methanesulfonate, Nethyl-A/-nitrosourea, diethyl sulfate, and ethyl methanesulfo nate at pH 6.5. Apurinic sites a...
