Thirty-seven metal chelate complexes of salts of 8-quinolinols with aromatic hydroxycarboxylic acids were screened by the disc-plate method against strains of five bacteria and five fungi. The copper (II) chelates of 8-quinolinolium salicylate and 8-quinolinolium-3'-hydroxy-2'-naphthoate showed outstanding antifungal and good antibacterial properties and appear to be potentially more economical...

STUDY DESIGN An external compression model was used to evaluate gene and protein expression in intervertebral discs with moderate disc degeneration. OBJECTIVE To determine messenger ribonucleic acid and protein expression levels of relevant disc components. SUMMARY OF BACKGROUND DATA An animal model of mechanically induced disc degeneration was developed and characterized histologically. Ho...

PURPOSE To conduct high-resolution imaging of the retinal nerve fiber layer (RNFL) in normal eyes using adaptive optics scanning laser ophthalmoscopy (AO-SLO). METHODS AO-SLO images were obtained in 20 normal eyes at multiple locations in the posterior polar area and a circular path with a 3-4-mm diameter around the optic disc. For each eye, images focused on the RNFL were recorded and a mont...

BACKGROUND Lumbar disc degeneration may be so advanced and asymmetrical that transforaminal access to the interbody space is limited. The extent of collapse may compromise the capacity to restore disc height and coronal balance in minimally invasive approaches. Although a variety of distractors are available for open approaches, currently there is no feasible distractor that is functional withi...

The aim of this study was to determine the ability of a disc susceptibility test using faropenem (10 μg) to predict carbapenemase activity in Enterobacteriaceae. A collection of 166 isolates of carbapenemase-producing Enterobacteriaceae (CPE) and 82 isolates of Enterobacteriaceae that produced other β-lactamases was compiled from diverse sources. Disc susceptibility testing was performed using ...

PURPOSE To investigate the effect of optic disc center displacement on retinal nerve fiber layer (RNFL) measurement determined by spectral domain optical coherence tomography (SD-OCT). METHODS The optic disc center was manipulated at 1-pixel intervals in horizontal, vertical, and diagonal directions. According to the manipulated optic disc center location, the RNFL thickness data were resampl...

Pathogenesis Hoerlein determined that intervertebral disc disease (IVDD) accounted for 2.02% of all diseases diagnosed in dogs (Hoerlein 1952). Incidence of IVDD peaks at 4 to 6 years of age in chondrodystrophic breeds and at 6 to 8 years in nonchondrodystrophic breeds (Priester 1976). The Dachshund had the highest frequency followed in succession by the Pekingese, Welsh corgi, Beagle, Lhasa Ap...

We present optical and X-ray spectra of a radio-quiet X-ray selected AGN, RX J1042+1212 (z=0.271). The hα and hβ emission lines are very broad (with full widths at half maximum of ∼10000 km s) and have double-peaked profiles. Such features are rarely observed in AGN in general but are even more unusual in radio-quiet objects. The analysis of the ROSAT PSPC data reveals a non-varying, unabsorbed...

BACKGROUND Tienchi (Panax notoginseng) has been used in conservative treatments for back pain as a major ingredient of many herbal medicines. This study aims to investigate the effects of a herbal medicine containing tienchi on compressed intervertebral discs in rats. METHODS Using an in vivo rat tail model, intervertebral disc compression was simulated in the caudal 8-9 discs of 25 rats by c...

BACKGROUND While considerable scientific effort has been devoted to studying how birds navigate over long distances, relatively little is known about how targets are detected, obstacles are avoided and smooth landings are orchestrated. Here we examine how visual features in the environment, such as contrasting edges, determine where a bird will land. METHODOLOGY/PRINCIPAL FINDINGS Landing in ...
