Although type E strains of Clostridium botulinum have been implicated in human botulism since 1936, no studies of the isolation or characterization of the toxin have been reported. Crude toxoids have been prepared by various workers for immunization of animals and preparation of antitoxin. Barron and Reed (1954) presented a systematic study of methods for preparation of crude alum precipitated ...
during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
We present a time-dependent (TD) linear-response description of excited electronic states within the framework of embedded mean-field theory (EMFT). TD-EMFT allows for subsystems to be described at different mean-field levels of theory, enabling straightforward treatment of excited states and transition properties. We provide benchmark demonstrations of TD-EMFT for both local and nonlocal excit...
the rhizome of anemarrhena asphodeloides is used as food and traditional chinese medicine for its hypoglycemic effect. the aim of this study was to investigate the isolation, purification and hypoglycemic activity of anemaran as the active component. the influence factors (isolation duration, ratio of residuals to water and extracting times) during the isolation process were evaluated. the opti...
virulence of the opportunistic yeast, candida albieans, involves the interplay of many complex changes including the yeast-hyphae transition, which mainly involves protein changes. cell wall mannoproteins are found to be the main cause of adherence of c. albieans to epithel ial cells in the first step of an infection process. in the present study, cell wall mannoproteins of intact yeast were pu...
OBJECTIVE To evaluate the safety of coadministering tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) and influenza vaccines during pregnancy by comparing adverse events after concomitant and sequential vaccination. METHODS We conducted a retrospective cohort study of pregnant women aged 14-49 years in the Vaccine Safety Datalink from January 1, 2007, to November 15, 2...
