In this study, adhesions on individual filopodial shafts were shown to control veil (lamellar) advance and to be modulated by guidance cues. Adhesions were detected in individual filopodia of sensory growth cones using optical recordings, adhesion markers, and electron microscopy. Veils readily advanced along filopodia lacking shaft adhesions but rarely advanced along filopodia displaying shaft...
Fine alignment of main ship power plants mechanisms and shaft lines provides long-term and failure-free performance of propulsion system while fast and high-quality installation of mechanisms and shaft lines decreases common labor intensity. For checking shaft line allowed stress and setting its alignment it is required to perform calculations considering various stages of life cycle. In 2012 J...
BACKGROUND Ipsilateral femoral neck and shaft fractures are rare, and currently available treatment methods each have their own benefits and limitations. Although reconstruction intramedullary nails have been considered to be effective alternative, clinical outcomes vary significantly in reports. METHODS Thirty-seven consecutive adult patients with 37 combined fractures were treated with reco...
Hair dysplasias are congenital or acquired alterations which often involve the hair shaft. Hair shaft abnormalities are characterized by changes in color, density, length and structure. Hair shaft alterations often result from structural changes within the hair fibers and cuticles which may lead to brittle and uncombable hair. The hair of patients with hair shaft diseases feels dry and looks lu...

The stomatostylet of Criconemoides curvature consists of three parts: tooth cone, shaft, and knobs. The tooth cone constitutes the outer conical covering and inner lining of the anterior half of the stylet lumen. The tooth cone is easily separated from the shaft by treating an isolated styler with 0.5% sodium hypochlorite. The posterior half of the shaft is cylindrical, tapering anteriorly to f...
background femur fracture is one of the most common fractures in children. certain parameters such as the patient’s age, the exact location of fracture, type of fracture, the mechanism of fracture, and the accompanying injuries determine which one of the many treatment techniques be used in each case. objectives we aimed to compare the results of close and open techniques in pediatric femoral s...
vascular injuries with acute or chronic arterial hemorrhage after femoral shaft fractures are a rare but a life-threatening complication. we observed a case of iatrogenic rupture of the profunda femoris artery after the internal fixation of a femoral shaft fracture. the pseudoaneurysm, presenting with painful expansile swelling and hemodynamic instability, together with the rupture was evident ...
A method for measuring shaft diameters is presented using structured light vision measurement. After calibrating a model of the structured light measurement, a virtual plane is established perpendicular to the measured shaft axis and the image of the light stripe on the shaft is projected to the virtual plane. On the virtual plane, the center of the measured shaft is determined by fitting the p...
background: fractures of the femoral shaft are mostly the result of high-energy accidents that also cause multiple trauma injuries, in particular ipsilateral knee and hip injuries. the purpose of this study was to investigate the incidence of injuries associated with femoral shaft fractures and how many of them were undetected. methods: we studied 148 patients (150 femoral shaft fractures) with...
