A 3.4-kbp nuclear (n) DNA sequence has greater than 99% sequence homology to three segments of the chloroplast (cp) genes rps2, psbD/C, and psaA respectively. Each of these cpDNA segments is less than 3 kbp in length and appears to be integrated, at least in part, into several (>5) different sites flanked by unique sequences in the nuclear genome. Some of(More)
RAPD (random amplified polymorphic DNA) markers were used to fingerprint eight commercially available apple rootstocks (Nertchinsk, Northern Spy, Osman, Heyer 12, M.1, M.9, M.26 and MM.106), 10 winter hardy offsprings derived from the cross of Nertchinsk x M.9, six winter hardy offsprings derived from the cross of Nertchinsk x M.26 and one winter hardy(More)
BACKGROUND CONTEXT Spring-back complication after open-door laminoplasty as described by Hirabayashi is a well-known risk, but its definition, incidence, and associated neurologic outcome remain unclear. OBJECTIVE To investigate the incidence and the neurologic consequence of spring-back closure after open-door laminoplasty. STUDY DESIGN A retrospective(More)
Pyogenic spondylitis is a neurological and life threatening condition. It encompasses a broad range of clinical entities, including pyogenic spondylodiscitis, septic discitis, vertebral osteomyelitis, and epidural abscess. The incidence though low appears to be on the rise. The diagnosis is based on clinical, radiological, blood and tissue cultures and(More)
Cervical spondylotic myelopathy is a common clinical problem. No study has examined the pattern of neurological recovery after surgical decompression. We conducted a prospective study on the pattern of neurological recovery after surgical decompression in patients with cervical spondylotic myelopathy. Patients suffering from cervical spondylotic myelopathy(More)
A gene critical to esophageal cancer has been identified. Functional studies using microcell-mediated chromosome transfer of intact and truncated donor chromosomes 3 into an esophageal cancer cell line and nude mouse tumorigenicity assays were used to identify a 1.61 Mb tumor suppressive critical region (CR) mapping to chromosome 3p14.2. This CR is bounded(More)
A family of related sequences associated with (TTTAGGG) n repeats has been cloned from the wheat cultivar Chinese Spring. These sequences reveal a high level of polymorphism between wheat varieties when used as restriction fragment length polymorphism (RFLP) probes. Although this family of sequences contains motifs homologous to the repeats in the telomeres(More)
At present, individual techniques, including intraoperative acute normovolemic hemodilution, use of tranexamic acid, use of intrathecal morphine, proper positioning, and modification of operative techniques, seem most promising for reducing perioperative blood loss and allogeneic blood transfusion in patients undergoing major spine surgery. Other techniques(More)
PURPOSE To explore the value of diffusion-tensor (DT) imaging in addressing the severity of cervical spondylotic myelopathy (CSM) and predicting the outcome of surgical treatment. MATERIALS AND METHODS From July 2009 to May 2012, 65 volunteers were recruited for this institutional review board-approved study, and all gave informed consent; 20 volunteers(More)
INTRODUCTION Tuberculosis of the spine is a still a common disease entity, not only in developing countries but is also returning in developed countries especially in the immune-compromised patients. Conservative treatment with chemotherapy is still the main stay of treatment. This article focuses on the clinical and radiological outcomes, and problems with(More)
