These results provide fundamental thermophysical properties for TiC for the first time and are important to theoretical and computational modeling of transition metal carbides.

“A high-flow maxillary arteriovenous malformation fed by multiple arteries, including bilateral internal maxillary arteries and ophthalmic artery, is reported. A combination of polyvinyl alcohol particles and N-butyl-cyanoacrylate mixed with lipiodol was progressively deposited within the distal vascular bed by transarterial superselective embolization of the branches of bilateral internal maxillary AZD6738 PI3K/Akt/mTOR inhibitor arteries, resulting in complete anatomic and
clinical cure. The authors feel that this approach is more secure and effective compared with transfemoral venous embolization and direct transosseous puncture. It also avoids mutilating surgery. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2009; 108: e17-e21)”
“Background: Surgical site infection remains a complication of spine surgery despite routine use of prophylactic antibiotics. Retrospective clinical studies of intrawound vancomycin use have documented a decreased prevalence of surgical
site infection after spine surgery. The purpose of the present study was to assess the efficacy of intrawound vancomycin powder in terms of eradicating a known bacterial surgical site contamination in a rabbit spine surgery model.
Methods: Twenty New Zealand White rabbits underwent lumbar partial laminectomy and wire implantation. The surgical sites were inoculated, prior to closure, by injecting 100 mu L of cefazolin-sensitive and vancomycin-sensitive Staphylococcus aureus (S. aureus)(1 x 10(8) colony-forming Epigenetics inhibitor units [CFU]/mL) into the wound. Preoperative cefazolin was administered to all rabbits, and vancomycin powder (100 mg) was placed into the wound of ten rabbits prior to closure. The rabbits were killed on postoperative day four, and tissue and wire samples were obtained for bacteriologic assessment. An independent samples t test was used to assess mean group differences, and a Fisher exact test was used to assess differences in categorical variables.
Results: The vancomycin-treated and the control rabbits were similar in weight (mean [and standard deviation], 4.1 +/- 0.5 kg and 4.0 +/- 0.4 kg, respectively; p = 0.60) and sex distribution and had similar durations of surgery (21.7 +/- 7.7 minutes-and 16.9 +/- 6.7 minutes; p = 0.15).
