Synthesizing a Gel Polymer Electrolyte for Supercapacitors, Assembling a Supercapacitor Using a Coin Cell, and Measuring Gel Electrolyte Performance.

Supercapacitors (SC) have attracted attention as energy storage devices due to their high density and long cycle performance. SCs used in devices operating in stretchable systems require stretchable electrolytes. Gel polymer electrolytes (GPEs) are an ideal replacement for liquid electrolytes.

Agarose Gel-Templating Synthesis of a 3D Wrinkled Graphene Architecture for Enhanced Supercapacitor Performance.

The increasing use of rapidly fluctuating renewable energy sources, such as sunlight, has necessitated the use of supercapacitors, which are a type of energy storage system with high power. Chemically exfoliated graphene oxide (GO) is a representative starting material in the fabrication of supercapacitor electrodes based on reduced GO (rGO). However, the restacking of rGO sheets driven by π-π stacking interactions leads to a significant decrease in the electrochemically active surface area, leading to a loss of energy density.

Distribution Pattern of Atherosclerosis in the Abdomen and Lower Extremities and Its Association with Clinical and Hematological Factors.

Comparison of Clinical and Hematologic Factors Associated with Stenosis and Aneurysm Development in Patients with Atherosclerotic Arterial Disease.

Background: Atherosclerosis is known to result in individuals with arterial stenosis or occlusion. Alternatively, certain atherosclerotic arteries develop aneurysms. However, there has been no clear explanation regarding the mechanism associated with this alternate clinical presentation.

Detrimental Effects of Endovascular Intervention in Active Rheumatoid Vasculitis.

Balloon angioplasty can cause shear stress and tear of the vascular endothelium during mechanical dilatation, leading to increased inflammation and coagulation reactions of the vascular endothelium. Herein, a worst case of active rheumatoid vasculitis is described, where due to progressing ischemic necrosis of the leg, endovascular intervention was unavoidably performed in the presence of active rheumatoid vasculitis. After percutaneous balloon angioplasty, the patient developed recurrent thrombotic occlusion of the leg arteries, and finally, limb amputation resulted in despite vigorous treatment including medication, immunosuppression, catheter-directed thrombolysis, and post-thrombolysis anticoagulation.

Long-Term Survival of a Patient with Adenocarcinoma of the Esophagogastric Junction with a Portal Vein Tumor Thrombosis Who Underwent Palliative Total Gastrectomy: A Case Report.

Portal vein tumor thrombosis (PVTT) with advanced gastric cancer is very rare; when it occurs, it exhibits aggressive growth and carries a poor prognosis. In addition, definitive treatment has not been established due to insufficient data. Herein, we report a case of PVTT associated with an adenocarcinoma of the esophagogastric junction that was successfully controlled by means of a palliative total gastrectomy without surgical resection of the PVTT and administration of palliative continuous doxifluridine.

Alcohol Consumption, High-Density Lipoprotein Cholesterol, Antithrombin III, and Body Mass Index Are Associated with Great Saphenous Vein Reflux in the Thigh.

Prognostic Discrepancy of the 6th and 7th UICC N Classification for Lymph Node Staging in Gastric Cancer Patients after Curative Resection.

Background: The validity of N classification of the 7th edition of the American Joint Committee on Cancer/Union Internationale contre le Cancer (AJCC/UICC) tumor-node-metastasis (TNM) staging system is still under debate. The purpose of this study was to evaluate the prognostic efficacy of the 7th edition of the AJCC/UICC TNM staging system (focusing on N stage), in comparison with the 6th edition, at a single Eastern institution.

Methods: We analyzed 1,435 patients with gastric cancer who underwent curative resection performed from September 1998 to August 2003 at the Memorial Jin-Pok Kim Korea Gastric Cancer Center.

Simultaneous robotic subtotal gastrectomy and right hemicolectomy for synchronous adenocarcinoma of stomach and colon.

Simultaneous laparoscopy-assisted resection for synchronous stomach and colon cancers has been reported frequently; however, robot-assisted gastrectomy and colectomy for these conditions are rarely reported. We report the successful use of robotic surgery for synchronous cancers of the stomach and colon. A 71-year-old woman with no specific medical history was diagnosed with early gastric cancer at the gastric angle and right colon cancer after undergoing esophagogastroduodenoscopy and colonofiberoscopy.

A Giant Retroperitoneal Liposarcoma Encasing the Entire Left Kidney and Adherent to Adjacent Structures: A Case Report.

Retroperitoneal liposarcoma is a rare tumor. The dimension and weight of liposarcoma are variable; those over 20 kg are called 'giant liposarcoma'. Herein, we report giant retroperitoneal liposarcoma measuring 45 cm in diameter and 25 kg in weight encasing the entire left kidney and adherent to adjacent structures.

Gastric Schwannoma Mimicking Malignant Gastrointestinal Stromal Tumor Exhibiting Increased Fluorodeoxyglucose Uptake.

D-Dimer Levels and Vitamin K Antagonist Therapy in Deep Vein Thrombosis of the Legs.

Background: D-dimer levels are closely related to the clinical status of deep vein thrombosis (DVT). This study aimed to investigate the factors which were associated with the normalization of D-dimer level by vitamin K antagonist (VKA) therapy, the maintenance of normal D-dimer levels for 6 months during VKA therapy, and the recurrent elevations of D-dimer above normal level after VKA withdrawal, in DVT of the legs.

Methods: The 469 consecutive patients with first-episode leg swelling were examined.

The Prognostic Value of Circumferential Resection Margin Involvement in Patients with Extraperitoneal Rectal Cancer.

The prognostic influence of circumferential resection margin (CRM) status in extraperitoneal rectal cancer probably differs from that of intraperitoneal rectal cancer because of its different anatomical and biological behaviors. However, previous reports have not provided the data focused on extraperitoneal rectal cancer. Therefore, the aim of this study was to examine the prognostic significance of the CRM status in patients with extraperitoneal rectal cancer.

The Laterality of Deep Vein Thrombosis in the Pelvic and Lower Extremity Veins.

Purpose: This study aimed to determine whether deep vein thrombosis (DVT) predominantly occurred on a particular side in the pelvic and lower extremity veins.

Materials And Methods: Among 259 consecutive patients with leg swelling, 65 were confirmed to have DVT in the pelvis and lower extremities, and enrolled in this study. The serum levels of initial D-dimer, antithrombin III, tissue plasminogen activator, factor VIII, proteins C and S, anticardiolipin antibodies immunoglobulin (Ig) G and IgM and lupus anticoagulant were measured and analyzed retrospectively.

Neurological and electrophysiological parameters as outcome measurements for peripheral arterial occlusive disease.

Background: Ischemic monomelic neuropathy is not an uncommon complication of peripheral arterial occlusive disease (PAOD). However, many investigators have used revascularization, limb salvage, and complete wound healing rates instead of neurologic and electrophysiological parameters as outcome measurements of PAOD. The aim of the study is to investigate the neurologic and electrophysiological parameters associated with PAOD and to find the ideal tools for assessing PAOD.

Acute limb ischemia: surgical thromboembolectomy and the clinical course of arterial revascularization at ankle.

Surgical thromboembolectomy for acute limb ischemia using Fogarty catheter is basically a blind procedure. Therefore, the complete removal of thromboemboli in all calf arteries is difficult even if completion angiography or radiological intervention is performed. The purpose of this study is to identify whether limb salvage could be achieved if at least one ankle artery was revascularized by surgical thromboembolectomy.

Delayed rupture of the iliac artery after percutaneous angioplasty.

Rupture of the iliac artery during percutaneous angioplasty is a life-threatening condition that requires prompt diagnosis and treatment to rescue the patient. Recently, percutaneous angioplasty has become an outpatient procedure, but there is no reliable guideline for observation time in the hospital after percutaneous angioplasty. We describe a 67-year-old man with bilateral lesions in the iliac artery who experienced a delayed rupture of the iliac artery 2 days after percutaneous balloon angioplasty and placement of a self-expandable stent.
