STUDY DESIGN Large cohort study of volunteers aged over 50. OBJECTIVE To investigate influence of age and sex on cervical sagittal alignment among volunteers aged over 50. SUMMARY OF BACKGROUND DATA Few large-scale studies have described normative values in cervical spine alignment regarding age and sex among volunteers aged over 50. METHODS The study(More)
The interleukin (IL)-6 pathway plays an important role in recovery after spinal cord injury (SCI). The anti-IL-6 receptor antibody MR16-1 has been shown to suppress inflammation after SCI and promote recovery of motor function. The purpose of this study was to analyze the effects of MR16-1 on the expression patterns of phospholipids in the spinal cord in a(More)
STUDY DESIGN Prospective radiographical analysis using the cranial center of gravity (CCG) of sagittal vertical axis (SVA) in elderly asymptomatic individuals. OBJECTIVE To determine sex differences and age-related correlations of CCG and relationships between CCG and other spinopelvic parameters/health-related quality of life (HRQOL) measures. SUMMARY(More)
STUDY DESIGN This investigation consisted of a cross-sectional study and a retrospective multicenter case series. OBJECTIVE This investigation sought to identify the ideal lumbar lordosis (LL) angle for restoring an optimal pelvic tilt (PT) in patients with adult spinal deformity (ASD). SUMMARY OF BACKGROUND DATA To achieve successful corrective fusion(More)
T1 pelvic angle (TPA) and global tilt (GT) are spinopelvic parameters that account for trunk anteversion and pelvic retroversion. To investigate spinopelvic parameters, especially TPA and GT, in Japanese adults and determine norms for each parameter related to health-related quality of life (HRQOL). Six hundred and fifty-six volunteers (262 men and 394(More)
In this study, we analyzed the spatiotemporal alterations of phospholipid composition in the spinal cord of an amyotrophic lateral sclerosis (ALS) mouse model (G93A-mutated human superoxide dismutase 1 transgenic mice [SOD1(G93A) mice]) using imaging mass spectrometry (IMS), a powerful method to visualize spatial distributions of various types of molecules(More)
A recurrent laryngeal nerve injury is known as a complication referring to an anterior cervical spine surgery. However, hypoglossal nerve injury is not well known yet. Herein we report a rare case of a 39-years-old male with a hypoglossal nerve injury after C3/4 osteophyte resection with Smith-Robinson approach. In this case there appeared difficulties of(More)
BACKGROUND Glial and fibrotic scars inhibit neural regeneration after spinal cord injury (SCI). N-[3,4-dimethoxycinnamoyl]-anthranilic acid (tranilast) inhibits transforming growth factor β, alleviates allergic reactions, and decreases hypertrophic skin scars. We evaluated its ability to improve motor function and inhibit the spread of tissue damage in rats(More)
STUDY DESIGN A prospective, randomized, controlled study. PURPOSE The objective of this study was to evaluate the effectiveness of two techniques of skin preparation with povidone-iodine. OVERVIEW OF LITERATURE Preoperative skin preparation is important for preventing surgical site infection by reducing the bacteria in the surgical area. Povidone-iodine(More)
Peripheral nerve injury (PNI) triggers cellular and molecular changes in the spinal cord. However, little is known about how the polyunsaturated fatty acid-containing phosphatidylcholines (PUFA-PCs) are regulated in the spinal cord after PNI and the association of PUFA-PCs with the non-neuronal cells within in the central nervous system (CNS). In this(More)
