Background and Purpose— In pediatric moyamoya disease, there are few reports on the efficacy of surgical intervention for stroke prevention. We evaluated long-term outcomes indirect bypass surgery a relatively large number children with disease in single center. Methods— From August 1988 to December 2012, 772 underwent surgery. This study included 629 patients who were followed up >5 years, excluding syndrome. The mean clinical follow-up duration was 12 years (range, 5–29 years)....
Primary CNS tumors (PCNSTs) are originating from the brain and surrounding tissues. These account for a significant proportion of cancer deaths morbidity globally. Accurate epidemiologic data essential shaping clinical practices, research priorities, health care policies. This study presents latest 2020 national on PCNSTs Republic Korea (ROK) explores trends in incidence their societal implications context an aging population.
Abstract In this multi-center, assessor-blinded pilot study, the diagnostic efficacy of cCeLL-Ex vivo, a second-generation confocal laser endomicroscopy (CLE), was compared against gold standard frozen section analysis for intraoperative brain tumor diagnosis. The study conducted across three tertiary medical institutions in Republic Korea. Biopsy samples from newly diagnosed patients were categorized based on location and divided permanent analysis, vivo imaging. Of 74 55 patients, majority...
Lateral restraint is the primary stabilization mechanism associated with interlocking of aggregate particles in geogrid apertures. This paper presents findings from a laboratory study which quantifies local stiffness enhancement aggregates through micromechanical provided by two different types geogrids. These are applied to model resilient response characteristics geogrid-stabilized base course composite systems. Using three pairs bender elements as shear wave transducers, horizontal...
Brain metastasis is a common complication in cancer patients. Local recurrence after total resection of metastatic brain tumor has been frequently reported. In this study, we developed new hyperthermia device and applied it to patients intra-operatively study if treatment could reduce local recurrence. A 63 were enrolled the with an informed consent obtained from every patient. After tumor, was cavity. The surrounding tissue at 5 mm depth margin raised 42.5 °C for 60 minutes (Clinical...
Chondromas are benign tumor of cartilaginous tissue that is rarely found in spine. The authors document a rare case 72 year old male patient with cervical spinal chondroma compressing the cord. had symptoms motor and sensory deficits, dysphagia dysarthria. C1 C2 laminotomy was done removed. gradually recovered from his previous symptom after surgery.
Conventional 2-Dimensional magnetic resonance imaging-based neuronavigation systems can improve the maximal safe resection in brain tumor surgery but be unintuitive. A 3-Dimensional (3D)-printed model allows for a more intuitive and stereoscopic understanding of tumors adjacent neurovascular structures. This study aimed to identify clinical efficacy 3D-printed presurgical planning by focusing on differences extent (EOR).Thirty two neurosurgeons (14 faculty members, 11 fellows, 7 residents)...
Covers advancements in spacecraft and tactical strategic missile systems, including subsystem design application, mission analysis, materials structures, developments space sciences, processing manufacturing, operations, applications of technologies to other fields.
The purpose of this pilot study was to examine the safety and function newly developed cerebrospinal fluid (CSF) reservoir called V-Port.The V-Port consists a non-collapsible outlined with titanium cage connector for ventricular catheter be assembled. It is designed better palpated more durable multiple punctures than Ommaya reservoir. A total nine patients diagnosed leptomeningeal carcinomatosis were selected insertion. Each patient followed up evaluation month after operation.The average...
<title>Abstract</title> Glioblastoma (GBM) is a dynamic ecosystem with high plasticity where the complex interplay between different cellular components contributes to disease progression. Although single-cell RNA (scRNA)-seq has revealed remarkable heterogeneity of GBM, spatial organization its diverse cell types currently lacking. Here we present comprehensive dataset 115,914 transcriptomes across 32 tissue sections genotyped glioma samples. We maps 56 fine-grained components, including...
Objectives: This study explored the surgical indications for pituitary adenomas (PAs) in older patients by analyzing outcomes of transsphenoidal approach (TSA).Methods: We retrospectively analyzed aged 65 years or who underwent TSA from March 2020 to October 2023. evaluated preoperative and postoperative neurological endocrinological features, degree tumor resection, perioperative complications.Results: In total, 134 (20.5%; 70 men 64 women) (70-74 years: 48 patients, 75-79 14 ≥80 8...
최근 활발한 연구가 진행 중인 공중발사 방식은 극소형 위성을 매우 저렴한 비용으로 발사할 수 있는 효율적인 방법이다. 본 연구에서는 비교적 단순한 임무를 수행할 나노 방식을 이용하여 원 궤도에 올릴 로켓 시스템설계와 각 단별 계통 설계를 수행하였다. 이를 위하여 시스템의 WBS와 계통별 작동개념도를 정립하였고, 바탕으로 시스템 세부형상과 DMU를 구현하였다. Air-Launching is an effective method that can launch the 'Nanosat' with low launching cost. In this study, system and subsystem design of air rocket for nanosats which perform a simple mission, have been performed. For purpose, WBS MIRINAEⅡ, schematics defined first. Based on these results,...
Numerical investigation on the dynamic stall over an oscillating airfoil is presented. A Reynolds-Averaged Navier-Stokes (RANS) equations are coupled with transition transport for natural transition. Computational results considering turbulent compared fully computations and experimental data. Results prediction show closer correlation data than those assumption, especially in reattachment region.
