BACKGROUND It is estimated that upwards of 50,000 individuals suffer traumatic fracture of the spine each year, and the instability of the fractured vertebra and/or the local deformity results in pain and, if kyphosis increases, neurological impairment can occur. There is a significant controversy over the ideal management. The purpose of the study is to present clinical and radiographic result...

According to the prevalence of multidrug resistance bacteria, especially Pseudomonas aeruginosa, in which essential mechanism drug is ability possess an efflux pump by extrusion antimicrobial agents usually occurs, this study aims detect presence mexB gene some local isolates bacteria that show towards three antibiotics, out five. Sensitivity test antibiotics was performed on all using meropene...

At present study, carbon nanotube-graphene (CNT-G) supported PtAu, Au and Pt catalysts were prepared by microwave-assisted synthesis method to investigate the direct liquid-fed sodium borohydride/hydrogen peroxide (NaBH 4 /H 2 O ) fuel cell performance. Prepared characterized TGA, XRD, TEM, ICP-OES, cyclic voltammetry rotating disc electrode (RDE) voltammetry. The tested in a single NaBH with 2...

OBJECTIVE To characterize variability in the identification of the macular center among retinopathy of prematurity (ROP) experts. METHODS A printed set of 25 wide-angle retinal images was compiled from infants at risk for ROP using a commercially available camera. Ten recognized ROP experts were asked to mark the macular center on each image. For each image, we measured the distance from the ...

The aims of spinal deformity surgery are to achieve balance, relieve pain and prevent recurrence or worsening of the deformity.The main types of osteotomies are the Smith-Petersen osteotomy (SPO), pedicle subtraction osteotomy (PSO), bone-disc-bone osteotomy (BDBO) and vertebral column resection (VCR), in order of increasing complexity.SPO is a posterior column osteotomy in which the posterior ...

The diffraction of light inside the shadow, thrown by a small source of light, of a sphere and a circular disc of the same diameter, was studied, with special reference to the relative intensities of the central bright spots. With the source at about 2 metres from the obstacles, with a quarter-inch polished steel ball, the bright spot could be detected visually up to 3 cm behind the obstacle, w...

INTRODUCTION In the large-scale case-control study EPILIFT, we investigated the dose-response relationship between lifestyle factors (weight, smoking amount, cumulative duration of different sports activities) and lumbar disc disease. METHODS In four German study regions (Frankfurt am Main, Freiburg, Halle/Saale, Regensburg), 564 male and female patients with lumbar disc herniation and 351 pa...
