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...

To test the "traction fiber" model for metaphase positioning of bivalents during meiosis, kinetochore fibers of maloriented bivalents, induced during recovery from cold arrest, were analyzed with a liquid crystal polarizing microscope. The measured birefringence retardation of kinetochore fibers is proportional to the number of microtubules in a fiber. Five of the 11 maloriented bivalents analy...

Objective. The purpose of this study was to present a case report that demonstrated primary failure in a tooth traction that was subsequently treated with apicotomy technique. Case Report. A 10-year-old girl had an impacted upper right canine with increased pericoronal space, which was apparent on a radiographic image. The right maxillary sinus showed an opacity suggesting sinusitis. The presum...

Mechanical forces have key roles in regulating activation of T cells and coordination of the adaptive immune response. A recent example is the ability of T cells to sense the rigidity of an underlying substrate through the T-cell receptor (TCR) coreceptor CD3 and CD28, a costimulation signal essential for cell activation. In this report, we show that these two receptor systems provide complemen...

This paper investigates kinetic behavior of a planetary rover with attention to tire-soil traction mechanics and articulated body dynamics, and thereby study the control when the rover travels over natural rough terrain. Experiments are carried out with a rover test bed to observe the physical phenomena of soils and to model the traction mechanics, using the tire slip ratio as a state variable....

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...

The grouser height and soil conditions have a considerable influence on the tractive performance of single-track shoe. A bin-based research was conducted to assess shoe at different moisture contents clay loam soil. Eight (7.5, 12, 16.7, 21.5, 26.2, 30.7, 35.8, 38%) three heights (45, 55, 60 mm) were comprised during this study. parameters (thrust, running resistance, traction) determined by pe...

Ann R Coll Surg Engl 2012; 94: 359–372 Many lower extremity, pelvic and acetabular fractures require traction as first aid management prior to definitive fixation. While skin traction and Thomas splints are generally available, weights to provide countertraction are often missing or in parts of the hospital remote to the emergency department. A sharps bin (Sharpsguard® orange 11.5; Daniels, Oxf...
