The level of significance
was alpha = 0.01 (after Bonferroni correction for 5 comparisons).
Results. All 3 stabilization techniques significantly decreased range of motion across C0-C2 compared to the intact spine (P < 0.01). There was no statistical difference among the 3 stabilization methods in flexion/extension and axial rotation. In lateral bending, the technique using C2 crossing laminar screws demonstrated a trend toward increased range of motion compared to the other 2 techniques. CT scans in both axial and sagittal views demonstrated greater proximity to the vertebral artery in the pedicle and transarticular screw techniques compared to the crossing laminar screw technique.
Conclusion. Occipitoatlantoaxial stabilization
techniques using C2 crossing laminar screws, C2 pedicles screws, and C1-C2 transarticular DZNeP cell line screws offer similar bio-mechanical stability. Using the C2 crossing find more laminar screw technique may offer an advantage over the other techniques due to the reduction of the risk to the vertebral artery during C2 screw placement.”
“Pasteurella multocida serotype A:3 is a Gram-negative bacterial pathogen, one of the causative agents of shipping fever of cattle. In this study, outer membrane protein H (ompH) and Pasteurella lipoprotein E (plpE) genes were cloned and plpEC-ompH fusion was constructed and expressed in Escherichia coil. Recombinant PlpE, OmpH and PlpEC-OmpH fusion proteins were purified and formulated with oil-based and oil-based CpG ODN adjuvants. Antibody responses in mice vaccinated with recombinant PlpE and PlpEC-OmpH proteins formulated with both adjuvants were significantly (p < 0.05) increased. However, a significant (p < 0.05) increment in serum IFN-gamma level was only observed upon immunization with oil-based CpG formulations. Protectivity of the vaccines were evaluated via intraperitoneal challenge
of mice with 10 LD50 of P. multocida A:3. The recombinant proteins PlpE and PlpEC-OmpH fusion conferred 100% protection when formulated with TPCA-1 ic50 oil-based CpG ODN while the protectivity was found to be 80% and 60%, respectively when only oil-based adjuvant was used in respective formulations. These findings indicated that the recombinant PIPE or PlpEC-OmpH fusion proteins formulated with oil-based CpG ODN adjuvant are possible acellular vaccine candidates against shipping fever.

“Chronic obstructive pulmonary disease (COPD) is one of the leading causes of death in the developed world and associated with a high individual and socioeconomic burden. Despite emerging preventive efforts and ongoing clinical trials, the frequency and mortality of COPD are expected to continue to rise over the next decades.
