BACKGROUND Preserving the C7 spinous process during cervical laminoplasty has been reported to prevent axial symptom. Some patients underwent laminectomy and fixation developed the symptom. The objective of this article was to investigate whether axial symptom can be reduced by preserving the C7 spinous process during cervical laminectomy and fixation with lateral mass screw. METHODS Between ...

Human lymphoblastic leukemia cells of line CEM-C7 are glucocroticoid-sensitive and contain glucocorticoid receptors of wild-type characteristics. EL4 mouse lymphoma cells are resistant to lysis by glucocorticoids due to mutant receptors that exhibit abnormal DNA binding. Hybrids between the two cell lines were prepared and analyzed with respect to glucocorticoid responsiveness and to receptor t...

Mutants of Corynebacterium diphtheriae C7(beta) that are resistant to the inhibitory effects of iron on toxinogenesis were identified by their ability to form colonies surrounded by toxin-antitoxin halos on agar medium containing both antitoxin and a high concentration of iron. Chromosomal mutations were essential for the altered phenotypes of four independently isolated mutant strains. During ...

Artificial disc replacement has been widely used in the lumbar spine since the 1980s, and more recently in the cervical spine. However, artificial disc replacement in the cervicothoracic and thoracic regions is very rare. A 43-year-old otherwise healthy male suffered from right sided cervicobrachialgia. X-rays and MRI revealed left C5/6, C6/7 and C7-T1 disc herniation, compromising the neural f...

Objective To assess whether cervical spinal cord atrophy heralds the onset of progressive MS. Methods We studied 34 individuals with radiologically isolated syndrome (RIS) and 31 patients with relapsing-remitting MS (RRMS) age matched to 25 patients within a year of onset of secondary progressive MS (SPMS). Two raters independently measured (twice per rater) the cervical spinal cord average seg...

Brachial plexus lesions most often occur in multiple trauma. We report a case of 37-year-old patient who presented an upper left limb total sensitivomotor deficit and amyotrophy after cervical Cervical magnetic resonance imaging (MRI) was performed. It noted pseudomeningoceles at the levels C6-C7, C7-D1, D1-D2 T1 hyposignal , T2 STIR hypersignal not enhanced by injection Gadolinium extending fo...

Corynebacterium diphtheriae and Corynebacterium glutamicum each have one gene (cat) encoding catalase. In-frame Δcat mutants of C. diphtheriae and C. glutamicum were hyper-sensitive to growth inhibition and killing by H(2)O(2). In C. diphtheriae C7(β), both catalase activity and cat transcription decreased ~2-fold during transition from exponential growth to early stationary phase. Prototypic O...

Clinically, injuries of C5-C7 of the brachial plexus cause falling of the wrist and fingers in infants but not in adults unless 4 consecutive spinal nerves are injured. The purpose of this study was to compare the constituent difference of spinal nerves in the radial nerve between pup and adult rats.A group of 16 pup rats and a group of 16 adult rats were each divided into 2 groups of 8 (P1 and...

A series of new ditriphenyltin(IV) dicarboxylate complexes general formula (Ph3SnOOC-Pz)2R with Pz: pyrazole and R: alkyl or ether, have been synthesized from bipyrazoledicarboxylic acid hydroxytripheyltin. These complexes, noted C1-C7, characterized by IR, 1H 13C NMR spectroscopies. The molecular structures C3: 1,3-Bis[(5-methyl-2-H-3-triphenyltincarboxylate pyrazol)]propane C7: Bis[(2-methyl-...

BACKGROUND Cervical interlaminar epidural injections are performed frequently in managing chronic neck and upper extremity pain, although less commonly than lumbar interlaminar epidural injections. Recently, the US Food and Drug Administration warnings and safeguards to prevent neurologic complications. These were developed by the Multi-Society Pain Workgroup have taken center stage for all typ...
