Sera from 452 patients and blood donors were tested for antibodies to Tryp-anosoma cruzi. The complement fixation test and a counterelectrophoresis test were used. The results showed that both tests agreed in 92% of the sera. However, the counterelectrophoresis test was not as sensitive as the complement fixation test.
Prostanoid receptors (nomenclature as agreed by the NC-IUPHAR Subcommittee on Receptors [701]) are activated endogenous ligands prostaglandins PGD2, PGE1, PGE2 , PGF2α, PGH2, prostacyclin [PGI2] and thromboxane A2. Differences similarities between human rodent prostanoid receptor orthologues, their specific roles in pathophysiologic conditions reviewed [452]. Measurement of potency PGI2 A2 is h...
The authors assessed the psychological, neuropsychological, and electrocortical effects of human exposure to mixed colonies of toxigenic molds. Patients (N = 182) with confirmed mold-exposure history completed clinical interviews, a symptom checklist (SCL90-R), limited neuropsychological testing, quantitative electroencephalogram (QEEG) with neurometric analysis, and measures of mold exposure. ...
The kinetics of Ras activation by Son of sevenless (SOS) changes profoundly when Ras is tethered to membranes, instead of being in solution. SOS has two binding sites for Ras, one of which is an allosteric site that is distal to the active site. The activity of the SOS catalytic unit (SOScat ) is up to 500-fold higher when Ras is on membranes compared to rates in solution, because the allosteri...
