Objective: To investigate the clinical effect of Dynesys dynamic fixation for double-segmental lumbar disc herniation and the degeneration of adjacent segment. Methods: 52 patients, who received Dynesys dynamic fixation for double-segmental lumbar disc herniation in our hospital from Mar 2009 to Mar 2012, were enrolled as research subjects; among them, 34 were male and 18 were female with an av...
We present multi-wavelength spectroscopic data of the 106 day period interacting binary BY Crucis (Daems et al. 1997). The system consist of an early F-type supergiant that fills its Roche lobe and a more massive companion, hidden in a thick accretion disc. In the far-UV spectra (from 1200 Å to 1950 Å), strong emission lines of highly ionised elements are observed, superposed on a continuum. Bo...
Multiple thoracic disc herniations are rare, and few reports exist in the literature. Diagnosis of these herniations is often missed because of their lack of specific clinical presentation. They may be treated conservatively or surgically. We presented a 35-year-old woman with five contiguous level thoracic disc herniations. She was admitted with upper back pain. Magnetic resonance imaging show...
We present detailed scattering models confirming that distinctive variations in polarization across the broad Hα line, which are observed in a significant fraction of Seyfert 1 galaxies, can be understood in terms of a rotating line-emitting disc surrounded by a co-planar scattering region (the equatorial scattering region). The predicted polarization properties are: averaged over wavelength, t...
INTRODUCTION Discogenic low back pain (LBP) affects a considerable number of patients suffering from chronic LBP. Recently, a growing interest has emerged in minimally invasive treatment options for discogenic LBP. Intradiscal biacuplasty (IDB), which uses cooled radiofrequency technology to ablate nociceptors in the posterior aspect of the intervertebral disc, is one such option. We previously...
ISSN: 2319-7706 Volume 5 Number 3(2016) pp. 194-205 Journal homepage: http://www.ijcmas.com The present study was conducted to detect the presence of MBLs among the isolates of Klebsiella pneumoniae by phenotypical methods and genotypic multiplex polymerase chain reaction (PCR) method among neonates with sepsis. The study included neonates who were admitted to the neonatal intensive care unit (...
OBJECTIVE Lumbar disc degeneration (LDD) is an important cause of low back pain, which is a common and costly problem. LDD is characterised by disc space narrowing and osteophyte growth at the circumference of the disc. To date, the agnostic search of the genome by genome-wide association (GWA) to identify common variants associated with LDD has not been fruitful. This study is the first GWA me...
We present data from long ROSAT HRI observations of the intermediate polars YY Dra and V709 Cas which show that V709 Cas, like YY Dra, exhibits a double-peaked X-ray pulse profile. Neither system shows evidence for X-ray beat period or orbital modulation, so both must be disc-fed accretors seen at low inclination angles. We argue that the short spin periods of the white dwarfs in these objects ...
The key aspect of the very successful truncated disc model for the low/hard X-ray spectral state in black hole binaries is that the geometrically thin disc recedes back from the last stable orbit at the transition to this state. This has recently been challenged by direct observations of the low/hard state disc from CCD data. We reanalyze the Swift and RXTE campaign covering the 2006 outburst o...
