Development of a competency model and tailored assessment method for high school science teachers utilizing a flipped learning approach.

Many professional development programs aim to improve student outcomes by enhancing teacher competencies. Effective evaluation of these programs requires a clear delineation of the competencies to be gained. A competency model was developed to evaluate the impact of a teacher professional program that aimed to improve teachers' ability to effectively implement technologically engaged modules in a flipped classroom setting.

Evaluation of the effectiveness of 3D vascular stereoscopic models in anatomy instruction for first year medical students.

The head and neck region is one of the most complex areas featured in the medical gross anatomy curriculum. The effectiveness of using three-dimensional (3D) models to teach anatomy is a topic of much discussion in medical education research. However, the use of 3D stereoscopic models of the head and neck circulation in anatomy education has not been previously studied in detail.

Rethinking CME: an imperative for academic medicine and faculty development.

To help address the clinical care gap, a working group discussed the future of faculty development in academic medicine, explored problems within the large, current enterprise devoted to continuing medical education (CME), and described four domains core to its revitalization and reformation. These domains are (1) preparing and supporting an engaged clinician-learner, (2) improving the quality of knowledge or evidence shared, (3) enhancing the means by which to disseminate and implement that knowledge and evidence, and (4) reforming the patient, health care, and regulatory systems in and for which the process of CME exists. Reshaping these domains requires the consideration of a more seamless, evidence-based, and patient-oriented continuum of medical education.

Antibacterial activity of synthetic fire ant venom: the solenopsins and isosolenopsins.

Background: We determined the in vitro activity of 9 synthetic fire ant venom alkaloids (+/-)-solenopsin A, (2R, 6R)-solenopsin A, (2S, 6S)-solenopsin B, (+/-)-isosolenopsin A, (2S, 6R)-isosolenopsin A,(2R, 6S)-isosolenopsin A, (+/-)-isosolenopsin B, (2S, 6R)-isosolenopsin B, and (2R, 6S)-isosolenopsin B against 6 species of bacteria (Streptococcus pneumoniae, Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Stenotrophomonas maltophilia, and Pseudomonas aeruginosa).

Methods: The minimum inhibitory concentration and minimum bacteriocidal concentration were determined in accordance with the Clinical Laboratory Standards Institute guidelines. Time kill studies used American Type Culture Collection bacterial isolates tested at 5 times the minimum inhibitory concentration.

Gender differences in the antinociceptive effect of tramadol, alone or in combination with gabapentin, in mice.

Gender difference in the antinociceptive effect of tramadol and gabapentin (alone or in combination) were investigated in mice. For investigation of acute antinociceptive effect, tramadol and gabapentin were administered to mice by intraperitoneal injection and per os, respectively, and antinociceptive activity was measured by the tail-flick test 30 min after drug administration. For investigation of the development of antinociceptive tolerance to analgesics, mice were injected with tramadol (60 mg/kg), alone or in combination with gabapentin (75 mg/kg), twice daily for seven consecutive days and the tail-flicks were tested on experimental days 1, 3, 5 and 7.
