[Purpose] This study aimed to determine static balance according to hip joint angle of the unsupported leg during one-leg standing. [Subjects and Methods] Subjects included 45 healthy adult males and females in their 20s. During one-leg standing on the non-dominant leg, the position of the unsupported leg was classified according to hip joint angles of point angle was class. Static balance was ...

This study investigated how young healthy subjects control their equilibrium in situations of instability specifically elicited by a reduced capacity of force production in the postural muscle system. Ten subjects displaced a bar forward with both hands at maximal velocity toward a target while standing on the dominant leg (UNID), on the nondominant leg (UNIND), or on both legs. In each stance ...

We report loss- and gain-of-function analyses that identify essential roles in development for Drosophila transcription factor AP-2. A mutagenesis screen yielded 16 lethal point mutant alleles of dAP-2. Null mutants die as adults or late pupae with a reduced proboscis, severely shortened legs (approximately 30% of normal length) lacking tarsal joints, and disruptions in the protocerebral centra...

This study investigated whether the use of superimposed whole-body vibration (WBV) during cross-education strength training would optimise strength transfer compared to conventional cross-education strength training. Twenty-one healthy, dominant right leg volunteers (21 ± 3 years) were allocated to a strength training (ST, m = 3, f = 4), a strength training with WBV (ST + V, m = 3, f = 4), or a...

INTRODUCTION Piebaldism is an autosomal dominant disorder characterized by the congenital absence of melanocytes in the affected areas of skin and hair due to mutations of the KIT protooncogene, which affects the differentiation and migration of melanoblasts. CASE REPORT A 3 1/2 month old male infant was admitted to hospital due to depigmentation of skin in the area of forehead, trunk and ext...

More than a century ago, two Italian dermatologists independently described a new keratotic disorder [1,2] which was called porokeratosis by Mibelli [1]. After these first descriptions, at least four variants of porokeratosis have been recognized. Clinically all these dermatological disorders are characterized by diffuse annular lesions surrounded by a raised, sharply marginated, keratotic bord...

BACKGROUND: Isokinetic testing is often used to provide coaches with important information about the physical status of athletes. Therefore, a number of studies is focused on the assessment of the relationship between isokinetic and functional tests. The results of a limited number of studies indicate that the relationship changes in different training periods. OBJECTIVE: The aim of the study w...

Motor adaptation, or alteration of neural control in response to a perturbation, is a potential mechanism to facilitate motor learning for rehabilitation. Central nervous system deficits are known to affect locomotor adaptation; yet we demonstrated that similar to adults following stroke, children with unilateral brain injuries can adapt step length in response to unilateral leg weighting. Here...

Broad interest in quantum spin liquid (QSL) phases was triggered by the notion that they can be viewed as insulating with preexisting electron-pairs, such upon light doping might automatically yield superconductivity. Yet despite intense efforts, definitive evidence is lacking. We address problem of a lightly doped QSL through large-scale density-matrix renormalization group study $t$-$J$ model...

The investigation aims at static examination and determination of differences for three age groups: under 13, 13–15 years old over 15, all practitioners the martial art karate do. This occured level main parameters, measured using FreeMed baropodometric platform Free Step software by Sensor Medica: plantar surface areas, location pressure center (C) inside support polygon, imbalances noticed Pm...
