PURPOSE To evaluate cell survival and tumorigenicity of human embryonic stem cell-derived retinal pigment epithelium (hESC-RPE) transplantation in immunocompromised nude rats. Cells were transplanted as a cell suspension (CS) or as a polarized monolayer plated on a parylene membrane (PM). METHODS Sixty-nine rats (38 male, 31 female) were surgically(More)
BACKGROUND Few studies focus on pediatric spinal cord injury (SCI) and there is little information regarding the cause, anatomic level, and high risk population of SCI in children. This study aims to investigate the incidence and risk factors of pediatric SCI. METHODS A nationwide cohort of 8.7 million children aged<18 years in an 11-year period was(More)
Palm lines, which consist of principal lines and wrinkles, are stable and essential traits for palmprint-based individual identification and can be extracted in low-resolution images. However, the research on palm-line detection has done little. Due to special properties of palmprint, in addition to the structure feature, width of the palm-line, which(More)
OBJECT This study aimed to calculate the incidence and prevalence of ossification of the posterior longitudinal ligament (OPLL) in the cervical spine with its comorbid disability. METHODS Using an 11-year nationwide database in Taiwan (National Health Insurance Research Database), this retrospective study cohort analyzed the incidences of cervical OPLL(More)
OBJECT This study aimed to determine the age- and sex-specific incidence of cervical spondylotic myelopathy (CSM) and its associated risk of causing subsequent spinal cord injury (SCI). METHODS Using the National Health Insurance Research Database (NHIRD), a 12-year nationwide database in Taiwan, this retrospective cohort study analyzed the incidence of(More)
This study used an 11-year nationwide database to analyze the incidence of spinal cord injury (SCI) in subgroups by age, gender, injury level, etiology, and socioeconomic status. The National Health Insurance Research Database of Taiwan, covering over 99% of the population accumulated from 1998 to 2008, was analyzed. All SCI patients>20 years of age and(More)
BACKGROUND The incidence of symptomatic adjacent segment disease (ASD) after anterior cervical diskectomy and fusion (ACDF) was reported as 2.9%/y in a previous cohort of 374 patients. Few other data corroborate the incidence and natural history of ASD. OBJECTIVE To calculate the incidence of ASD after ACDF that required secondary fusion surgery. (More)
OBJECTIVE Spinal cord injury (SCI) is associated with a higher risk of cardiovascular diseases but whether or not the risk of cerebrovascular disease also increases remains unclear. This study aimed to evaluate the incidence of stroke in patients with disability caused by SCI. METHODS Study subjects were identified from a nationwide cohort of 18,690,066(More)
Tongue line refers to the surface of the tongue covered with fissures or lines in deep or shallow shape and is one type of important features in clinical practice of Traditional Chinese Tongue Diagnosis (TCTD). However , it is hard to extract tongue lines completely due to the large variation of the widths of tongue lines and the strong noise caused by the(More)
