Somatic cell nuclear transfer (SCNT) technology has recently been used to generate animals with a common genetic composition. In this study, we report the derivation of pluripotent embryonic stem (ES) line (SCNT-hES-1) from cloned human blastocyst. The SCNT-hES-1 cells displayed typical ES morphology and surface markers were capable differentiating into embryoid bodies in vitro forming teratomas vivo containing derivatives all three germ layers severe combined immunodeficient mice. After...
To report our experience with preoperative neurosurgical planning in stereoscopic virtual reality environment for 21 patients intra- and extra-axial brain tumors vascular malformations.A system called VIVIAN (Virtual Intracranial Visualization Navigation) was developed the Dextroscope, a which operator reaches both hands behind mirror into computer-generated three-dimensional (3-D) object moves manipulates real time natural 3-D hand movements. Patient-specific data sets from multiple imaging...
Treatment options are limited for patients with high-risk non-muscle-invasive bladder cancer (NMIBC) disease recurrence after bacillus Calmette-Guérin (BCG) treatment and who ineligible for/refuse radical cystectomy. FGFR alterations commonly detected in NMIBC. We evaluated the activity of oral erdafitinib, a selective pan-fibroblast growth factor receptor (FGFR) tyrosine kinase inhibitor, versus intravesical chemotherapy NMIBC select FGFR3/2 following BCG treatment.
Background The ectodomain of matrix protein 2 (M2e) influenza A virus is a rationale target antigen candidate for the development universal vaccine against as M2e undergoes little sequence variation amongst human strains. Vaccine-induced M2e-specific antibodies (Abs) have been shown to display significant cross-protective activity in animal models. M2e-based constructs be more protective when administered by intranasal (i.n.) route than after parenteral injection. However, i.n....
To develop and evaluate a deep learning model for automated segmentation detection of bone metastasis on spinal MRI. We included whole spine MRI scans adult patients with metastasis: 662 series from 302 (63.5 ± 11.5 years; male:female, 151:151) three study centers obtained between January 2015 August 2021 training internal testing (random split into 536 126 series, respectively) 49 20 (65.9 11:9) another center 2018 2020 external testing.

<i>Background and Purpose:</i> Although cardiac embolism has been shown to be the leading stroke mechanism of posterior cerebral artery (PCA) territory infarction, intrinsic PCA atherosclerotic disease may play a more important role in regions where intracranial diseases are prevalent. We aimed assess etiologies pattern infarction Korean population. <i>Method:</i> reviewed consecutive patients with acute who underwent diffusion-weighted MRI (DWI) magnetic resonance...
The purpose of this study was to determine reliable MRI findings suggesting disk herniation with cartilage endplate in the lumbar spine.The records 73 patients who underwent spinal and microdiskectomy between March 2005 January 2009 were searched find those diagnosis confirmed during surgery. following morphologic features assessed: posterior corners (posterior marginal nodes, dorsal corner defects, Modic changes, osteophytes), mid endplates (endplate irregularities, changes), heterogeneous...

Purpose To propose a new magnetic resonance (MR) classification system based on axial images for cervical compressive myelopathy (CCM) (Ax-CCM system), to assess the interobserver agreement with Ax-CCM system, and evaluate relationship between patterns baseline severity of CCM subsequent surgical outcome. Materials Methods The institutional review board approved this retrospective study. A total 202 patients (male-to-female ratio, 128:84; mean age ± standard deviation, 56.3 years 11.9;...
Opportunistic screening of osteoporosis using computed tomography (CT) should be optimized according to CT protocols. However, date, no study has evaluated the different contrast phases urography in screening. To compare diagnostic performance opportunistic osteoporosis. In this single-center retrospective study, 210 consecutive patients (181 men, 29 women; mean age = 72.0 ± 9.5 years) who underwent both and dual-energy X-ray absorptiometry (DXA) within 3 months July December 2020 were...

Population-based studies of the incidence tuberculosis in cancer patients according to type are limited. We investigated cancer-specific a nationwide population-based cohort country with an intermediate burden tuberculosis. used mandatory National Health Insurance claims data construct adults (aged 20–99 years) newly diagnosed malignancies other than lung cancer, from January 2008 December 2012. Patients who developed this period were identified and general population. Standardized ratios...
We evaluated and compared the effectiveness of intra-articular injection hip joint using hyaluronic acid steroid in patients with femoroacetabular impingement (FAI). Thirty FAI clinically radiologically were enrolled underwent (TA) or (HA) at 0-weeks cross-over 2-weeks without clinical response decrease pain intensity less than 2-point. Patients followed up to 12-weeks for (Numeric rating scale, NRS: 0-10), disability score (HOOS), oral medication adverse events. In 17 cross-over, HOOS was...
