The major limitation of the long term success of percutaneous coronary interventions is the development of restenosis, which occurs in 30–50% of patients within six months. 2 Restenosis is the result of a complex pathophysiological process in the arterial wall in response to balloon dilatation or stent insertion. For many years the hallmark of this response to injury was considered to be the de...

OBJECTIVES The goal of this study was to use serial (postirradiation and follow-up) volumetric intravascular ultrasound (IVUS): 1) to evaluate the actual distribution of gamma radiation in human in-stent restenosis (ISR) lesions, and 2) to analyze the relationship between neointimal regrowth and the delivered radiation dose. BACKGROUND The relationship between the neointimal regrowth and deli...

I t was observed by Hershey, Kamen, Kennedy, and Gest (1951) that bacteriophages are unstable if they contain radiophosphorus p82 of high specific activity. From day to day, progressively decreasing fractions of such populations of radioactive phage are still able to form plaques when plated on a sensitive bacterial strain, and the rate of loss of infective titer depends on the specific activit...

Abstract Oesophageal stents are meshed tubular implants designed to maintain patency of the oesophageal lumen and attenuate symptoms cancer. cancers account for one in twenty cancer diagnoses can lead dysphasia, malnutrition diminishment patient quality life (QOL). Self-expanding most common approach these symptoms. Recent advances oncological therapy have enabled survival beyond lifetime curre...

BACKGROUND Patients with acute coronary artery thrombosis often develop primary malignant ventricular arrhythmias (MVA) early after coronary occlusion. In contrast, acute ischemia induced by nonthrombotic balloon occlusion during routine coronary angioplasty rarely elicits such arrhythmias. This study was designed to assess the role of intracoronary thrombosis in arrhythmogenesis during acute i...

Sir, the big flooding in Thailand in 2011 is one of the problematic flooding in Asia. It causes several destroying to many things in the disaster areas. An important concern is on the effect on the setting with the radioactive elements usage. In Thailand, there are some places with radioactive elements including to the university, hospital as well as radioactive research center. Luckily, ...

results a total of 529 patients underwent kidney transplant surgery in our center. urologic complications among the three groups consisting of hydronephrosis, urinoma and collection did not have statistically significant differences. conclusions ureteral stent can be picked up with no increased risk of urologic complications at shorter intervals after the kidney transplantation surgery. patient...

Accidental or intentional release of radioactive materials into the living or working environment may cause radioactive contamination. In nuclear medicine departments, radioactive contamination is usually due to radionuclides which emit high energy gamma photons and particles. These radionuclides have a broad range of energies and penetration capabilities. Rapid detection of radioactive contami...

Abdominal aortic coarctation is an extremely rare vascular pathology. Its etiology can be congenital or acquired. Here we present a case of acquired infrarenal abdominal coarctation in a 66-year-old woman who complained of low back and legs pain. She had no signs of resting lower limb ischemia, with diminished distal pulses and normal blood pressure in upper and lower extremities. Magnetic reso...
