Cell chirality: emergence of asymmetry from cell culture.
Increasing evidence suggests that intrinsic cell chirality significantly contributes to the left-right (LR) asymmetry in embryonic development, which is a well-conserved characteristic of living organisms. With animal embryos, several theories have been established, but there are still controversies regarding mechanisms associated with embryonic LR symmetry breaking and the formation of asymmet...
متن کاملChallenging Postural Tasks Increase Asymmetry in Patients with Parkinson’s Disease
The unilateral predominance of Parkinson's disease (PD) symptoms suggests that balance control could be asymmetrical during static tasks. Although studies have shown that balance control asymmetries exist in patients with PD, these analyses were performed using only simple bipedal standing tasks. Challenging postural tasks, such as unipedal or tandem standing, could exacerbate balance control a...
متن کاملUnilateral Condylar Hyperplasia: A 3-Dimensional Quantification of Asymmetry
PURPOSE Objective quantifications of facial asymmetry in patients with Unilateral Condylar Hyperplasia (UCH) have not yet been described in literature. The aim of this study was to objectively quantify soft-tissue asymmetry in patients with UCH and to compare the findings with a control group using a new method. MATERIAL AND METHODS Thirty 3D photographs of patients diagnosed with UCH were co...
متن کاملMandibular asymmetry: a three-dimensional quantification of bilateral condyles
INTRODUCTION The shape and volume of the condyle is considered to play an important role in the pathogenesis of the mandibular deviation. Curvature analysis is informative for objectively assess whether the shape of the condyles matches that of the glenoid fossa. In this study, a three-dimensional (3-D) quantification of bilateral asymmetrical condyles was firstly conducted to identify the spec...
متن کاملQuantification of Cerebral Grey and White Matter Asymmetry from MRI
Several studies have reported the presence of morphological differences between the brains of schizophrenic patients and normal controls, such as a decrease of normal cerebral asymmetries. While current MR imaging techniques make it feasible to measure brain morphology in vivo, the significance of image-derived measurements obtained by slice by slice manual delineation of structures of interest...
