Recent studies suggest that the intracoronary administration of bone marrow (BM)-derived mesenchymal stem cells (MSCs) may improve left ventricular function in patients with acute myocardial infarction (AMI).However, there is still argumentative for safety and efficacy MSCs AMI setting.We thus performed a randomized pilot study to investigate AMI.Eighty after successful reperfusion therapy were randomly assigned received an autologous BM-derived into infarct related artery at 1 month.During...
Three-dimensional stress development was observed in silicon surrounding the Cu-filled through-silicon via (TSV) structures undergoing thermal annealing process. We show here, using a multiwavelength micro-Raman spectroscopy system, that behavior of after step is dependent on initial state as well geometry and directionality TSV array. The warping curve for postannealed with reference preannealed distinctively observed. Furthermore, introduction stress-free point also attributed to...
This study was conducted to determine the proper hand position on sternum for external chest compression generate a maximal haemodynamic effect during cardiopulmonary resuscitation (CPR).114 patients with cardiac arrest who underwent CT after successful from January 2006 August 2009 were included in study. To evaluate area of chambers subjected compression, each chamber under measured using cross-sectional at three different locations: internipple line (point A), halfway between point A and...
To assess whether computed tomography (CT) conversion across different scan parameters and manufacturers using a routable generative adversarial network (RouteGAN) can improve the accuracy variability in quantifying interstitial lung disease (ILD) deep learning-based automated software.This study included patients with ILD who underwent thin-section CT. Unmatched CT images obtained scanners from four (vendors A-D), standard- or low-radiation doses, sharp medium kernels were classified into...
Placental transmogrification is a very rare lung disease, where the alveoli resemble chorionic villi of placenta, and this change characteristic finding.A 31-year-old female patient presented with cough dyspnea that had begun 2 weeks prior to admission.Along giant bulla found in left upper field, subsegmental consolidation was also identified lingular segment on plain chest radiograph CT scan.Wedge resection performed remove bulla.Pathologic examination resected revealed destruction normal...
The purposes of this study were to investigate dual-energy CT findings predictive clinical outcome and determine the incremental risk stratification benefit compared with ventricular diameter ratio in patients acute pulmonary embolism.A retrospective evaluation was conducted cases 172 embolism who underwent CT. Ventricular relative perfusion defect volume measured. primary endpoints death within 30 days embolism-related death.A 1 or greater associated increased (hazard ratio, 3.822; p =...
An artificial intelligence (AI) model using chest radiography (CXR) may provide good performance in making prognoses for COVID-19.We aimed to develop and validate a prediction CXR based on an AI clinical variables predict outcomes patients with COVID-19.This retrospective longitudinal study included hospitalized COVID-19 at multiple medical centers between February 2020 October 2020. Patients Boramae Medical Center were randomly classified into training, validation, internal testing sets (at...
An accurate characterization for the deformation behavior of conductive particles is important: 1) to understand anisotropic adhesive (ACA) interconnection and 2) optimize ACA bonding parameter. This paper introduces an experimental technique, which has been developed allow continuous monitoring characteristics a single particle. The load-deformation curve particle measured, provides quantitative estimation mechanical electrical metal-coated polymer spheres used in ACAs. Based on result...
Primary thymic mucinous adenocarcinoma is an extremely rare aggressive subtype of carcinoma. With a review literatures, only nine cases have been reported up to present. A 36-year-old woman was admitted for further evaluation and treatment mediastinal mass. The patient had no medical history cancer. clinicoradiological examination disclosed tumor elsewhere. After the surgical excision mass, it grossly round semi-solid mass with mucin-filled cystic areas. Microscopically solid areas showed...
Numerical simulation of micro-bumped flip chips mounted on a TSV interposer is conducted to study the thermal performance package.

The Korean Society of Thoracic Radiology (KSTR) recently constructed a nation-wide coronavirus disease 2019 (COVID-19) database and imaging repository, referred to the cohort COVID-19 (KICC-19) based on collaborative efforts its members. purpose this study was provide summary clinico-epidemiological data KICC-19.
In this paper, thermomechanical and rheological properties of nonconductive pastes (NCPs) depending on silica filler contents diluent were investigated. And then, thermal cycling (T/C) reliability flip chip assembly using selected NCPs was verified. As the content increased, changed. The higher added, glass transition temperature (T/sub g/) storage modulus at room became while coefficient expansion (CTE) decreased. On other hand, significantly affected by content. viscosity NCP decreased...
Objective To compare the diagnostic performance of contrast-enhanced radial T1-weighted gradient-echo 3-tesla (3T) magnetic resonance imaging (MRI) and computed tomography (CT) for detection visceral pleural surface invasion (VPSI). Visceral by non-small-cell lung cancer (NSCLC) can be classified into two types: PL1 (without VPSI), elastic layer pleura without reaching surface, PL2 (with full pleura. Materials methods Thirty-three patients with pathologically confirmed VPSI NSCLC were...
Objectives: Whether coronary artery changes are a main mechanism in the development of carbon monoxide (CO)-induced cardiomyopathy remains unknown. We investigated effects stenosis on presence or patterns CO-poisoned patients with myocardial injury defined as elevation troponin I.Materials and methods: This prospective observational study collected data from consecutive who were diagnosed CO poisoning during 24-month period. Transthoracic echocardiography (TTE) computed tomography...
Although respiratory infections, such as pneumonia, have long been recognized precipitators of exacerbation in patients with acute decompensated heart failure (ADHF), identifying signs concomitant pneumonia ADHF is a clinical diagnostic challenge. We evaluated the predictive value delta neutrophil index (DNI), new indicator for immature granulocytes, diagnosing superimposed presenting emergency department (ED).This was retrospective and observational study consecutive (>18 years old)...
Pulmonary Langerhans cell histiocytosis is an uncommon diffuse cystic lung disease in adults. In rare cases, it can involve extrapulmonary organs and lead to endocrine abnormalities such as central diabetes insipidus. A 42-year-old man presented with polyphagia polydipsia, well a dry cough dyspnea on exertion. Magnetic resonance imaging of the hypothalamic-pituitary system failed show posterior pituitary, which typical finding patients This condition was confirmed by water deprivation test,...
Kawasaki disease (KD) is an acute systemic vasculitis in children which causes coronary arterial dilatation (CAD) and gallbladder distension (GBD). There a dearth of investigating the relationship between severity KD GBD with lipid profiles.A total 80 patients 'complete KD' who were diagnosed from January 2005 to May 2009 was enrolled this study. Serum cholesterol {total, high density lipoprotein-cholesterol (HDL-C) low (LDL-C)}, triglyceride (TG), complete blood count, inflammation markers...

Abstract Aging and atherosclerotic progression can lead to geometric changes in the carotid arteries. We conducted a longitudinal study investigate bilateral retrospective of 177 subjects who underwent contrast-enhanced magnetic resonance angiography (MRA) at our clinic baseline 10 years after procedure. Semi-automated methods were used segment arteries obtain artery measurements. The mean age for total population was 70.7 ± 10.6 (male, 40.1%). time interval between all 130.2 8.1 months....
