STUDY DESIGN This is an in vitro biomechanical study. OBJECTIVE To compare the biomechanical stability of the 3 C1-C2 transarticular screw salvaging fixation techniques. SUMMARY AND BACKGROUND DATA Stabilization of the atlantoaxial complex is a challenging procedure because of its complicated anatomy. Many posterior stabilization techniques of the atlantoaxial complex have been developed wi...

The optimum treatment of Type II odontoid fractures in the geriatric population remains controversial. Coexisting medical conditions encountered in the elderly patient often increase operative risk and make cervical immobilization difficult to tolerate. Previous studies have shown increased morbidity and mortality and decreased fusion rates for Type II odontoid fractures treated with cervical o...

Reactions of 2-X-2-(Y-phenyl)-l,3-indandiones (X = C1, Br; Y = H, p-N02, /?-CH30, m-CH30) with anions of acetylacetone, ethyl malonate nitromethane, and 2-nitropropane were carried out. It was found that the starting indandione was converted during the reaction into the anion of 2-(Y-phenyl)-l,3-indandione (/) and bis-2-(Y-phenyl)-l,3-indandione (II). The ratio of the products / and II was depe...

Levels of components of the classical and alternative complement pathways and the activity of the C3 nephritic factor (C3NeF) were measured in serum specimens from patients with type I (subendothelial deposits) and type II (intramembranous dense deposits) membranoproliferative glomerulonephritis (MPGN) and the results compared with the levels in normal subjects. Although C3 and C5 concentration...

INTRODUCTION The target of this comment is a recent and welcome paper (Gamez, 2014) that addresses foundational issues for neuralcorrelates-of-consciousness empiricism. This comment discusses whether Gamez’ assumptions actually allow the suggested framework to support the kind of theorydiscrimination necessary for advancing the field. Specifically, present discussions solely concern the theory-...

  The sporozoites of Theileria annulata invade bovine MHC II cells, where they differentiate into schizonts. The later can immortalize and induce fundamental changes in their host cells. Live attenuated vaccine is an important way of controlling T. annulata infection of cattle. Production is by prolonged cultivation of macroschizont-infected cells. The mechanisms underlying this transformation ...
