In the Laboratory of Traction and Rolling Stock systematic research into the methods of testing a traction drive, using the real models has been conducted. The aim of this research was to completely define all elements of the system for testing the main electrical and mechanical properties which include the selection of measuring transducers, the selection and implementation of the system for c...

This study was performed for the purpose of comparing the magnitude of cervical vertebral separation during cervical traction in supine and seated positions using home traction units. A repeated measures design with two within-subject factors (type of traction and time) was used. Seventeen asymptomatic volunteers received cervical traction in seated and supine position. Subjects received 5 minu...

The purpose of this study was to investigate the effects of cervical traction on the soleus H reflex amplitude in stroke patients. Cervical traction with intensity of 3 kgw was performed on six stroke patients. The soleus H reflex was evoked before, during, and after the cervical traction. All subjects showed smaller H reflex amplitudes in the second and third minutes after traction than before...

Running rails used as a return conductor and ungrounded scheme have been widely adopted in DC traction power systems. Due to the longitudinal resistance of running rails and insulation resistance of rail-to-ground, there will be a potential rise between running rails and the ground when return current flows through the running rails, which is known as rail potential. At present, abnormal rise o...

three cases who underwent surgery in different areas of the craniofacial region were reported with bradycardia developing intraoperatively during flap traction. many cases of the oculocardiac reflex during treatment of the orbital region have been reported in the literature. this manuscript recorded that reflex bradycardia can occur during traction or stretching of any structure innervated by t...

background prostate traction is one way to control post-prostatectomy bleeding. the most popular method involves traction with a catheter fixed to the thigh with adhesive bands. however, this method has its own drawbacks. objectives we aimed to simplify this traction procedure and to overcome its disadvantages. patients and methods from 2007 - 2015, a new method was used to control post-prostat...

Seventy-eight supracondylar fractures of the humerus in children were reviewed to compare four kinds of treatment: closed reduction and immobilization in a cast or splint, overhead skeletal traction, side-arm skeletal traction, and Dunlop's skin traction. The skeletal traction device usually used was a winged screw of our own design. The arms treated in overhead traction had significantly less ...

Focal adhesions (FAs) are integrin-based transmembrane assemblies that connect a cell to its extracellular matrix (ECM). They are mechanosensors through which cells exert actin cytoskeleton-mediated traction forces to sense the ECM stiffness. Interestingly, FAs themselves are dynamic structures that adapt their growth in response to mechanical force. It is unclear how the cell manages the plast...

Transmigration of leukocytes across the endothelial barrier is a tightly controlled process involving multiple steps, including rolling adhesion, firm adhesion, and then penetration of leukocytes through the endothelial monolayer. While the key molecular signals have been described in great detail, we are only just beginning to unveil the mechanical forces involved in this process. Here, using ...

PURPOSE To evaluate the efficacy of triamcinolone as an aid in vitreous visualization during 3D-vitrectomy for the treatment of diabetic vitreomacular traction. METHODS Prospective interventional study in patients with symptomatic vitreomacular traction. Pre- and postoperative assessments included visual acuity, retinography, intraocular pressure and optical coherence tomography. All patients...
