Changes in the rate of synthesis of cellular constituents were studied in detached cucumber cotyledons (Cucumis sativus L. cv. Ohio) after treatment with benzyladenine (BA). BA treatment stimulated RNA and DNA syntheses. The stimulation of RNA synthesis occurred within the lag phase preceding BA-induced growth, while that of DNA synthesis came during the(More)
A cross-sectional study of the data retrospectively collected by chart review. This study aimed to clarify screw perforation features in 129 consecutive patients treated with computer-assisted cervical pedicle screw (CPS) insertion and to determine important considerations for computer-assisted CPS insertion. CPS fixation has been criticized for the(More)
The senescent cultured tobacco (Nicotiana tabacum L.) cells, XD6S, when extracted with customary procedure, contained much auxin. The use of new extraction procedure using dichloromethane which does not extract much indolepyruvic acid revealed that the cultured tobacco cells do not contain measurable auxin at any stage of culture.
We developed a new multilevel registration technique for pedicle screw (PS) insertion that has the capability of registering three consecutive vertebrae simultaneously, using a reference frame set to one of the caudal vertebrae. PSs are inserted in the consecutive and adjacent one or two vertebrae. This study aimed to investigate the perforation rates of(More)
BACKGROUND CONTEXT Osteoid osteoma of the thoracic spine is relatively uncommon and is often difficult to diagnose, especially when patients do not complain of pain. PURPOSE This study aims to describe an unusual case of scoliosis caused by osteoid osteoma of the thoracic spine that was challenging to diagnose. STUDY DESIGN/SETTING A case report of a(More)
STUDY DESIGN Seventy-five patients who had been treated for lumbar spinal stenosis (LSS) were reviewed retrospectively. PURPOSE Invasion into the paravertebral muscle can cause major problems after laminectomy for LSS. To address these problems, we performed spinous process-splitting laminectomy. We present a comparative study of decompression of LSS(More)
STUDY DESIGN A retrospective study. PURPOSE The present study aimed to evaluate mid-term results of cervical pedicle screw (CPS) fixation for cervical instability. OVERVIEW OF LITERATURE CPS fixation has widely used in the treatment of cervical spinal instability from various causes; however, there are few reports on mid-term surgical results of CPS(More)
BACKGROUND CONTEXT The EuroQol (EQ-5D) is a widely used comprehensive measure of health-related quality of life. There has been no study that has evaluated the health-related quality of life before and after the surgical reconstruction of rheumatoid arthritis (RA) cervical spine lesions using EQ-5D. PURPOSE The present study aimed to evaluate the(More)
BACKGROUND Despite remarkable improvement in Cobb angle after surgery for scoliosis, many patients have a residual rib hump. We studied the factors responsible for this hump and their influence on patient satisfaction. METHODS We recruited 2 men and 38 women (mean age 14.9 years) who underwent skip pedicle screw fixation combined with direct vertebral(More)
