Results: Generally, resident ratings indicated that faculty showed positive teaching behaviors. Faculty self-assessment ratings were all lower (P<.025) than those assigned to them by the residents except for 1 component representative of “”feedback,” which approached significance (P=.04); 2 items, representative of “”promoting understanding and retention” and “”evaluation”, had mean scores of less than 3. At 3 months, compared with self-assessment at Boot Camp, faculty ratings suggested improved teaching behaviors in their simulation settings in the following: “”learning climate,” “”control of session,” “”communication of goals,” “”promoting understanding and
retention,” and MK-0518 “”evaluation.” The simulation environment was perceived as more positive for technical skills training in certain aspects compared with clinical setting: instructor reviewed function and operation of equipment with learner before session (representative of “”promoting understanding and retention”) and instructor allowed the learner ample time to practice (representative of “”control of session” and “”promoting understanding and retention”) (P<.025).
Conclusions: Simulation-based skills training is perceived by residents to be associated with positive teaching behaviors.
Faculty self-ratings indicate that they do not always use many of these teaching behaviors and that their Selleck PS-341 performance can be improved. The simulation setting may provide greater opportunity for positive teaching behaviors compared with the clinical environment. (J Thorac Cardiovasc Surg 2013;145:45-53)”
“Each symbiotic Chlorella of the ciliate Paramecium bursaria is enclosed in Oxygenase a perialgal vacuole membrane derived from the host digestive vacuole membrane. Alga-free paramecia and symbiotic algae can grow independently. Mixing them experimentally can cause reinfection. Earlier, we reported that the symbiotic algae appear to push the host trichocysts aside to become fixed beneath the host cell cortex during the algal reinfection process. Indirect immunofluorescence
microscopy with a monoclonal antibody against the trichocysts demonstrates that the trichocysts change their locality to form algal attachment sites and decrease their density beneath the host cell cortex through algal reinfection. Transmission electron microscopy to detect acid phosphatase activity showed that some trichocysts near the host cell cortex are digested by the host lysosomal fusion during algal reinfection. Removal of algae from the host cell using cycloheximide recovers the trichocyst’s arrangement and number near the host cell cortex. These results indicate that symbiotic algae compete for their attachment sites with preexisting trichocysts and that the algae have the ability to ensure algal attachment sites beneath the host cell cortex.”
