The morphogenetic process of cardiac looping transforms the straight heart tube into a curved tube that resembles the shape of the future four-chambered heart. Although great progress has been made in identifying the molecular and genetic factors involved in looping, the physical mechanisms that drive this process have remained poorly understood. Recent work, however, has shed new light on this...

background: diabetes is a common disease that can lead to metabolic abnormalities and chronic complications. today, the positive role of physical activity and exercise, especially walking in health human society and has been approved in prevention and control many complications including diabetes. today, the positive role of physical activities and exercise , especially hi wal king in the healt...

This paper describes a projection system using DLP projectors and parabolic mirrors to provide a 90◦ curved screen with a 4-to-1 aspect ratio. This display is intended to provide an ‘immersive’ experience for the user and facilitate a very large canvas on which to utilize multiple applications or single ones requiring a large screen. The resulting display has a 3072 × 768 pixel display area.

The study explored the effect of music on the temporal aspects of walking behavior in a real outdoor urban setting. First, spontaneous synchronization between the beat of the music and step tempo was explored. The effect of motivational and non-motivational music (Karageorghis et al., 1999) on the walking speed was also studied. Finally, we investigated whether music can mask the effects of vis...

Background: Thalassemia is the most common hereditary disease in Iran. Cardiac complications and cardiac symptom have been identified as the major problem, which has profound impact on the mental health of patients with thalassemia. One method of reducing this impact is an exercise plan. Aim: The purpose of this study was to examine the effect of a designed Walking plan on the mental health and...

Objectives: There exists no study concerning gait pattern while engaging in dual-task activities on different sizes of mobile devices. The present study aimed to compare gait patterns during normal walking, walking with smartphone use, and walking with tablet use.  Methods: Seventeen healthy female participants with an age range of 19-24 years (mean±SD age: 20.29±1.61 years, weight: 49.82±4.46...

objectives: this paper describes further improvement and preliminarily evaluation of a novel viscoelastic ankle-foot prosthesis prototype. the objective was to control the ankle hysteresis at slow and normal walking speeds. methods: inspired by the ankle biomechanics, in which the hysteresis differs based on the gait speeds, a manually damping control mechanism imbedded in the prosthesis for ad...

background: over the years, various types of orthoses have been designed to assist subjects with spinal cord injury (sci) to stand and walk. however, the functional performance of the orthoses has not been adequate, that is, patients experience stability problems, consume excessive energy during ambulation, and generally require assistance in donning and doffing the devices. this research is ai...

abstract background: hypertension in pregnancy is one of the prevalent disorders resulting in maternal death. the aim of this study was to investigate the effect of stretching exercise and walking on changes of blood pressure in nulliparous women during pregnancy. materials and methods: this was a quasi-experimental trial that consisted three groups of women who took part in pre- and post-tests...
