A quasi-line graph is a graph in which the neighbourhood of any vertex can be covered by two cliques; every line graph is a quasi-line graph. Reed conjectured that for any graph G, χ(G) ≤ 1 2 (∆(G) + 1 + ω(G)) [13]. We prove that the conjecture holds if G is a quasi-line graph, extending a result of King, Reed and Vetta, who proved the conjecture for line(More)
Findings at 56 arthrotomies in a series of children of 15 years of age and younger, who were suspected of having meniscal lesions were recorded and correlated with the preoperative history, findings from physical examination and some diagnostic tests. The results suggest that both the most common pathological lesions and the mode of presentation of meniscal(More)
The cases of two patients with delayed paraplegia after segmental spinal instrumentation with sublaminar wiring are reported. Both patients had complex spinal deformities and had transient neural deficits after the first-stage procedure of anterior release and spine fusion. They had uneventful spinal-cord monitoring during the second-stage procedure of(More)
The koala, Phascolarctos cinereus, is a biologically unique and evolutionarily distinct Australian arboreal marsupial. The goal of this study was to sequence the transcriptome from several tissues of two geographically separate koalas, and to create the first comprehensive catalog of annotated transcripts for this species, enabling detailed analysis of the(More)
Effective pedicle diameter (EPD), the maximal cancellous diameter of the spinal pedicle, demonstrates the maximal diameter available for transpedicular screw placement. The pedicles of 16 spines from T6 to L5 were measured directly with a graduated mean increase in the EPD ranging from 4.8 mm at T6 to 5.9 mm at L5. This direct pedicle measurement was(More)
STUDY DESIGN Review of 27 consecutive patients who underwent video-assisted thoracoscopic surgery (VATS) in the prone position for anterior release and discectomy. OBJECTIVES To convey the benefits and safety of this new technique for treating spinal deformities through VATS. SUMMARY OF BACKGROUND DATA All reports using VATS for spinal deformities(More)
PURPOSE Two noninvasive delivery strategies for VEGF/PDGF receptor tyrosine kinase inhibitors (RTKI) were explored that exploited uveal retention as a means for establishing an ocular drug depot: a single oral "loading" dose and topical administration. METHODS Melanin binding was confirmed by centrifugation and mass spectrometry. Ocular retention was(More)
