Fluctuating asymmetry is mainly interpreted as an indicator of developmental instability, while directional asymmetry of the upper limbs is associated with handedness. The association patterns between adult androgen levels and fluctuating as well directional asymmetry patterns are still unclear. In the present study, the association between adult androgen levels, body size and directional as we...

Cynodon is a genus of plants with forage potential that has attracted the interest of breeders. These species have high morphological variability in a large number of varieties and cytotypes, hampering identification. This study aimed to determine the karyotype asymmetry index among accessions of Cynodon to discriminate between them. Karyotype symmetry was based on three estimates, which were c...

[1] Oblique convergence is the general rule along convergent boundaries. Such convergence produces asymmetric deformation (topography) along the collision boundary. To quantify this asymmetry, we develop a method that allows us to calculate the asymmetry in topography with respect to a reference line drawn perpendicular to the collision boundary. The asymmetry in topography is presented as a nu...

Background The aetiology of temporomandibular joint disorders (TMD) is multifactorial, whereas occlusal disharmony is one of the predisposing factors. Researchers still discuss the relation between occlusion and TMD. Objective The study aims to investigate the relation between static occlusal parameters and TMD clinical symptoms using T-Scan II analysis system. Material and methods The samp...

The mechanism by which growing neurites sense and respond to small applied electrical fields is not known, but there is some evidence that the entry of Ca(2+) from the external medium, with the subsequent formation of intracellular Ca(2+) gradients, is important in this process. We have employed two approaches to test this idea. Xenopus spinal neurites were exposed to electrical fields in a cul...

OBJECTIVE To assess the effects of a new neuroprosthesis (NESS L300) designed to ameliorate foot drop on gait symmetry and rhythmicity during walking. DESIGN Twenty-four patients (mean age: 54.0 +/- 13.5 yrs) with chronic hemiparesis (5.8 +/- 5.2 yrs) whose walking was impaired by foot drop. Subjects walked for 6 mins while wearing force-sensitive insoles, once with and once without the neuro...

OBJECTIVE To compare effectiveness on correcting cranial and ear asymmetry between helmet therapy and counter positioning for deformational plagiocephaly (DP). METHODS Retrospective data of children diagnosed with DP who visited our clinic from November 2010 to October 2012 were reviewed. Subjects ≤10 months of age who showed ≥10 mm of diagonal difference were included for analysis. For DP tr...

We present new functional equations for the species of plane and of planar in the sense of Harary and Palmer, 1973 2-trees and some associated pointed species. We then deduce the explicit molecular expansion of these species, i.e.a classiication of their structures according to their stabilizers. Therein result explicit formulas in terms of Catalan numbers for their associated generating series...

The purpose of this investigation was to (a) examine how asymmetry in lower extremity lean mass influenced force and power asymmetry during jumping, (b) determine how power and force asymmetry affected jump height, and (c) report normative values in collegiate athletes. Force and power were assessed from each limb using bilateral force plates during a countermovement jump in 167 division 1 athl...
