That certain vessels might be at so-called geometric risk of atherosclerosis rests on assumptions wide interindividual variations in disturbed flow and a direct relationship between lumen geometry. In testing these often-implicit assumptions, the present study aimed to determine whether investigations local factors can indeed rely surrogate markers flow.Computational fluid dynamics simulations were performed carotid bifurcation geometries derived from MRI 25 young adults. Disturbed was...
Purpose On the basis of benefits frontline radiation in early-stage, extranodal, natural killer (NK)/T-cell lymphoma (ENKTL), we conducted a phase II trial concurrent chemoradiotherapy (CCRT) followed by three cycles etoposide, ifosfamide, cisplatin, and dexamethasone (VIPD). Patients Methods Thirty patients with newly diagnosed, stages IE to IIE, nasal ENKTL received CCRT (ie 40 52.8 Gy cisplatin 30 mg/m 2 weekly). Three VIPD (etoposide 100 days 1 through 3, ifosfamide 1,200 33 mg 4) were...
Background: Patient-specific computational fluid dynamics (CFD) models derived from medical images often require simplifying assumptions to render the simulations conceptually or computationally tractable. In this study, we investigated sensitivity of image-based CFD carotid bifurcation regarding blood rheology. Method Approach: three different patient-specific were carried out assuming: a reference high-shear Newtonian viscosity, two non-Newtonian (shear-thinning) rheology models, and...
This work integrates incompressible smoothed particle hydrodynamics (ISPH) with machine learning (ML) to examine the uses of two different domain shapes, spline star-domain, and triangle on double diffusion nano-encapsulated phase change material (NEPCM). The effects thermal radiation exothermic chemical reactions are conducted in this work. hexagonal-shaped is located inside center star-shape carrying (Th&Ch). left/right walls star shape kept at (Tc&Cc) other have an adiabatic condition. It...
<abstract> <p>This work simulates thermo-diffusion and diffusion-thermo on heat, mass transfer, fluid flow of nano-encapsulated phase change materials (NEPCM) within a complex cavity. It is novel study in handling the heat/mass transfer inside highly complicated shape saturated by partial layer porous medium. In addition, an artificial neural network (ANN) model used conjunction with incompressible smoothed particle hydrodynamics (ISPH) simulation to forecast mean Nusselt...
Although serum beta-2 microglobulin (B2M) has been suggested as a prognostic factor for mantle cell lymphoma (MCL), additional data are necessary to confirm its role. Between November 2005 and July 2014, total of 52 patients with MCL were identified from the database Asan Medical Center, Seoul, Korea. Pretreatment B2M information was available in 50 (96%). Overall survival (OS) compared according level cut-off value 2.5 mg/L. The median international index (MIPI) score 5.84 (range...
Abstract Author Summary Lessons Learned Addition of cetuximab may affect tolerability and, in turn, eventual outcomes. The incidence prior human papillomavirus infection has emerged as an important variable that can confound trials enrolling patients with oropharyngeal cancer. Background. We investigated the efficacy when added to induction chemotherapy followed by concurrent chemoradiotherapy (CCRT) locally advanced head and neck squamous cell carcinoma. Methods. Patients were randomized...
(18)F-FDG PET and PET/CT have shown clinical usefulness in the initial staging follow-up of patients with salivary malignancy. Therefore, we evaluated utility preoperative staging, determining extent neck node involvement, surgical planning for duct carcinoma (SDC) major gland.We 18 SDC who were assessed by CT before surgery. The sensitivity, specificity, accuracy, predictive values predicting primary tumor site involvement at each dissected level comparing imaging findings pathologic nodal...
Abstract Background Assaying for the parasitic lactate dehydrogenase (pLDH) is widely used as a rapid diagnostic test (RDT), but efficacy of its serological effectiveness in diagnosis, that antibody detection ability, not known. The genetic variation Korean isolates was analysed, and recombinant protein pLDH evaluated serodiagnostic antigen Plasmodium vivax malaria. Methods Genomic DNA purified, gene P. amplified from blood samples 20 patients. came five epidemic areas: Bucheon-si, Gimpo-si,...
Background and Purpose Since the long-term survival rate has improved in laryngeal cancer patients who receive radiotherapy, concerns about postradiation complications (including carotid atherosclerosis) have increased.We followed changes common artery (CCA) after radiotherapy identified underlying risk factors.Methods Consecutive with underwent between January 1999 December 2009 had received computed tomography (CT) both pre-and postradiotherapy were enrolled.Changes wall thickness vessel...
Conclusions: p16 immunohistochemistry (IHC) status correlated with less exposure to smoking and/or alcohol in Korean patients locally advanced tonsillar squamous cell carcinoma (TSCC), and was an independent prognostic factor for survival. Objective: TSCC is more likely be human papillomavirus (HPV)-positive than other head neck (HNSCC) subtypes. The objective of this study ascertain the HPV determine its relationship clinical parameters prognosis. Methods: TSCCs 79 who were treated between...
