STUDY DESIGN Comparative analysis and correlational research design were used to investigate the association between anthropometry and biomechanical performance among asymptomatic subjects and patients with low back pain (LBP). OBJECTIVES To examine the association between pelvic asymmetry and patterns of trunk motion in asymptomatic and LBP subjects. Secondary objective was to investigate th...

For simplicity, we restrict attention to subregions of the plane. Let Ω ⊆ R 2 be the closure of a bounded, open, connected set of area |Ω| with piecewise continuously differentiable boundary and perimeter . The classical isoperimetric inequality:

BACKGROUND AND PURPOSE Asymmetry of the hippocampus is regarded as an important clinical finding, but limited data on hippocampal asymmetry are available for the general population. Here we present hippocampal asymmetry data from the Dallas Heart Study determined by automated methods and its relationship to age, sex, and ethnicity. MATERIALS AND METHODS 3D magnetization-prepared rapid acquisi...

Fluctuating asymmetry refers to small random deviations from perfect symmetry in bilaterally paired structures; it is thought to reflect an organism’s ability to cope with genetic and environmental stress during development and its utility as an indicator of such stresses is based on the assumption that perfect symmetry is an a priori expectation for the ideal state of bilateral structures. Flu...

Some degree of asymmetry of the body is normal. Occasionally, htwever, the disparity, affecting part or the whole of one limb or even half the body, is sufficiently marked to attract attention. In examples which occur after an illness of childhood, such as poliomyelitis, the cause of the asymmetry is easily recognized to be underdevelopment of the affected limb. There are, however, patients in ...

PURPOSE To establish the prevalence of nasopupillary asymmetry (difference in nasopupillary distances) in the population and its relation with the interpupillary distance. METHODS A retrospective descriptive study was conducted by reviewing of 1262 medical records. The values of nasopupillary asymmetry and the interpupillary distance were obtained. A statistical analysis was made and the corr...

problems and defects in mucus clearance that are characteristic of primary cilliary dyskinesia, a disorder of motile cilia. Anything related to signaling? This is one of the most exciting aspects of primary cilium biology and BBSome function. In the ear of bbs knockout animals, hair cells frequently fail to align with one another, a characteristic of defective planar cell polarity (PCP). Althou...

Biological membranes consist of lipid bilayers. The lipid compositions between the two leaflets of the plasma membrane differ, generating lipid asymmetry. Maintenance of proper lipid asymmetry is physiologically quite important, and its collapse induces several cellular responses including apoptosis and platelet coagulation. Thus, a change in lipid asymmetry must be restored to maintain "lipid ...
