Numerous definitions and analytical techniques for elemental (or black) carbon (EC) have been published in the scientific literature, but still no generally accepted inter-disciplinary definition exists. EC is not a single chemical compound, but is mainly composed of two parts of carbon contents: combustion residues from pyrolysis and combustion emissions(More)
To obtain a histopathologic diagnosis at the site of a biliary obstruction, we recently have performed 24 cases of biliary biopsy using gastrofiberscopic biopsy forceps (Olympus, Tokyo, Japan) via transhepatic tracts provided in the course of the procedure of percutaneous biliary drainage. Histopathologic diagnosis was successfully made at the first attempt(More)
Bisphenol A (BPA) and alkylphenols (APs) are well-known endocrine disrupting chemicals (EDCs) which may threat the next generations' health. We performed biomonitoring of these phenols in colostrums to assess risk of the phenols in breast-fed neonates. Study subjects were the lactating mothers who delivered babies within 2 weeks (N = 325; 30.67 ± 3.45(More)
PURPOSE We evaluated the usefulness of intracranial stent implantation for treating patients with atherosclerotic stenosis and with recurrent, ischemic, neurological symptoms despite having undergone medical therapy. MATERIALS AND METHODS Between March 2004 and April 2010, we attempted intracranial, stent-assisted angioplasty in 77 patients with 85(More)
OBJECTIVE The purpose of our study is to retrospectively determine the diagnostic role of (18)F-FDG PET/CT at the primary lesion site in burned patients with chronic nonhealing ulcers who are suspected of having Marjolin ulcers. MATERIALS AND METHODS Thirty-three burn scar contractures with nonhealing chronic ulcer in 28 patients were included in this(More)
A patient with a sciatic artery aneurysm, which is so rare that only 31 cases have been reported in the literature to date, was treated successfully with transcatheter arterial embolization (TAE) alone. Potentially risky and difficult surgery was avoided. This was the first trial with a good result. TAE alone is simple, safe and effective method for the(More)
OBJECTIVE This study aimed to investigate the expression of osteopontin (OPN), p2lras, and CD44V6 in breast cancer tissues, and to analyze the relationships between their expression and a patient's clinicopathological characteristics and five-year survival rate. MATERIALS AND METHODS Streptavidin-peroxidase immunohistochemistry was used to detect the(More)
During forced respiratory movement such as coughing, complications can occur, including abdominal muscle rupture. We report a case of spontaneous tear of the internal oblique muscle resulting from violent cough diagnosed by sonography. The physiology of cough and the possible pathophysiologic mechanism of this case is discussed.
BACKGROUND T-SPOT.TB is a sensitive test that detects interferon-gamma producing T-cells in tuberculosis patients following stimulation with tuberculosis-specific antigens. Our study was aimed to investigate the possible causes of false negative results of the test by analyzing the patients with positive acid-fast bacilli (AFB) culture and negative(More)
BACKGROUND A high-voltage electrical burn is often associated with deep muscle injuries. Hidden, undetected deep muscle injuries have a tendency for progressive tissue necrosis, and this can lead to major amputations or sepsis. MRI has excellent soft tissue contrast and it may aid in differentiating the areas of viable deep muscle from the areas of(More)
