The authors present a unique case of an 11-year-old child with spontaneous fusion of his occiput to C1–C2 following traction,manipulative reduction, and halo immobilization for refractory atlantoaxial rotatory fixation. The child initially presented with torticollis, neck pain, and headaches and underwent numerous chiropractor manipulations over 9 months with alleviation of his neck pain and he...

Published data on any association between the CYP2E1 RsaI/PstI (c1/c2) polymorphism and liver cancer risk among east Asians are inconclusive. The aim of this Human Genome Epidemiology (HuGE) review and meta- analysis was to derive a more precise estimation of the relationship. A literature search of Pubmed, Embase, Web of science and CBM databases from inception through July 2012 was conducted....

Let M be a point set, C1 and C2 mutually exclusive closed subsets of M, and K a connected subset of M such that (1) K contains no points of the set C1 + C2 and (2) both C1 and C2 contain limit points of K. Then K, together with its limit points in C1 + C2, will be caUed a set K(C1,C2)M. If M has the property that for every two of its mutually exclusive closed subsets Cl, C2 and every connected ...

Pang, Haiyan, and Khalil N. Bitar. Direct association of RhoA with specific domains of PKC. Am J Physiol Cell Physiol 289: C982–C993, 2005. First published June 1, 2005; doi:10.1152/ajpcell.00364.2004.— Previous studies performed at our laboratory have shown that agonistinduced contraction of smooth muscle is associated with translocation of protein kinase C (PKC)and RhoA to the membrane and th...

Previous studies performed at our laboratory have shown that agonist-induced contraction of smooth muscle is associated with translocation of protein kinase C (PKC)-alpha and RhoA to the membrane and that this interaction is due to a direct protein-protein interaction. To determine the domains of PKC-alpha involved in direct interaction with RhoA, His-tagged PKC-alpha proteins of individual dom...

We reviewed 6 patients with atlanto-axial (C1-2) deformities secondary to neglected odontoid fractures. All patients (except one with recent injury) were asymptomatic for a long period before development of neck pain or myelopathy, despite obvious subluxation and kyphotic deformities at the C1-2 joint complex. Patients were treated conservatively, except for one who underwent posterior spinal f...

RATIONALE Traumatic C1-2 dislocation associated with contiguous or noncontiguous cervical spine injury is rare. Moreover, there have been no reports describing traumatic C1-2 dislocation associated with multiple contiguous and noncontiguous cervical injuries. PATIENT CONCERNS The authors present a case of a 20-year-old male with painful limitation of motion of the neck. This complex cervical ...

STUDY DESIGN Retrospective study. PURPOSE To propose a new radiographic index for occipito-cervical instability. OVERVIEW OF LITERATURE Symptomatic atlanto-occipital instability requires the fusion of the atlanto-occipital joint. However, measurements of occipito-cervical translation using the Wiesel-Rothman technique, Power's ratio, and basion-axial interval are unreliable because the radi...

We study a 2× 2 system of non-strictly hyperbolic conservation laws arising in three– component gas flooding for enhanced oil recovery. The system is not strictly hyperbolic. In fact, along a curve in the domain one family is linearly degenerate, and along two other curves the system is parabolic degenerate. We construct global solutions for the Riemann problem, utilizing the splitting property...
