Cysticercosis caused by infection with embryonated eggs of Taenia solium is an important cause of neurological disease worldwide. On the basis of mitochondrial DNA analysis, T. solium is divided into 2 (African/American and Asian) genotypes. Glycoproteins (GPs) in cyst fluid purified from the 2 genotypes of T. solium were characterized and compared with the recombinant chimeric T. solium-Ag1V1/...
b ackground: toxoplasmosis is a serious disease in immunocompromised patients and pregnant women. differentiation of acute and chronic infection is a major challenge in serodiagnosis of the disease. since the aim of this study was to assess the diagnostic utility of recombinant sag1 (rec- sag1) for the detection of toxoplasma -specific igm antibodies in human sera, by an enzyme-linked immunosor...
Natural transformation contributes to the maintenance and to the evolution of the bacterial genomes. In Streptococcus pneumoniae, this function is reached by achieving the competence state, which is under the control of the ComD-ComE two-component system. We present the crystal and solution structures of ComE. We mimicked the active and non-active states by using the phosphorylated mimetic ComE...
By applying the Arkenol process using highly concentrated sulfuric acid, various biomass feedstocks, including cedar tree, rice straw, newspaper, and bagasse, were successfully processed and converted into glucose and xylose for fermentation usage in a flash fermentation reactor in which the performance of National Renewable Energy Laboratory's patented rec-Zymomonas mobilis 31821 (pZB5) after ...
This paper conveys the laboratory investigation of storage stability CRM binder as a basic study. The was produced through wet process in laboratory. percentages crumb rubber used for rubberized were 5%, 10%, 15% and 20%. samples prepared according to ASTM D7173. In order evaluate properties each part binders, tests carried out rotational viscosity viscoelasticity, separation index assessed wit...
BACKGROUND The Regional Committee for Africa of the World Health Organization (WHO) in 2001 expressed concern that some health-related studies undertaken in the Region were not subjected to any form of ethics review. In 2003, the study reported in this paper was conducted to determine which Member country did not have a national research ethics committee (REC) with a view to guiding the WHO Reg...
BACKGROUND Most studies of the association between diesel exhaust exposure and lung cancer suggest a modest, but consistent, increased risk. However, to our knowledge, no study to date has had quantitative data on historical diesel exposure coupled with adequate sample size to evaluate the exposure-response relationship between diesel exhaust and lung cancer. Our purpose was to evaluate the rel...
