Recent studies suggest that chromosomal rearrangements play a significant role in speciation by preventing recombination and maintaining species persistence despite interspecies gene flow. Factors conferring adaptation or reproductive isolation are maintained in rearranged regions in the face of hybridization, while such factors are eliminated from(More)
OBJECTIVES Sexual dimorphism in the human bony pelvis is commonly assumed to be related to the intensity of obstetrical selective pressures. With intense obstetrical selective pressures, there should be greater shape dimorphism; with minimal obstetrical selective pressures, there should be reduced shape dimorphism. This pattern is seen in the nondimorphic(More)
The utilization of bedside ultrasound by an increasing number of medical specialties has created the need for more ultrasound exposure and teaching in medical school. Although there is a widespread support for more vertical integration of ultrasound teaching throughout the undergraduate curriculum, little is known about whether the quality of ultrasound(More)
The objective of this study was to determine whether the three-dimensional shape of the bony pelvis differs between women with and without pelvic floor disorders (PFDs). We predict that the levator ani attachment points for the pelvic floor are further displaced from one another in affected relative to unaffected women. Pelvic shape was quantified by(More)
Surgical anatomy is taught early in medical school training. The literature shows that many physicians, especially surgical specialists, think that anatomical knowledge of medical students is inadequate and nesting of anatomical sciences later in the clinical curriculum may be necessary. Quantitative data concerning this perception of an anatomical(More)
To map the retreat of the Asulkan Glacier in Glacier National Park, British Columbia, five dating techniques were applied: lichenometry, dendrochronology, moraine interpretation, dendroclimatology, and airphoto interpretation. Trees on both the distal and proximal sides of lateral moraines were cored and their ages determined. These data sets were used(More)
INTRODUCTION The debate regarding anatomy laboratory teaching approaches is ongoing and controversial. To date, the literature has yielded only speculative conclusions because of general methodological weaknesses and a lack of summative empirical evidence. Through a meta-analysis, this study compared the effectiveness of instructional laboratory approaches(More)
Deficits in retention of anatomy knowledge from the preclinical years to clinical application on the wards have been well documented in the medical education literature. We developed and evaluated a web and laboratory-based curriculum to address deficits in anatomy knowledge retention and to increase anatomy knowledge recall through repetition and(More)
