INTRODUCTION AND OBJECTIVES Abdominal sonography is regarded as a quick and effective diagnostic tool for acute abdominal pain in emergency medicine. However, final diagnosis is usually based on a combination of various clinical examinations and radiography. The role of sonography in the decision making process at a hospital with advanced imaging capabilities versus a hospital with limited imag...
BACKGROUND Mass screening program for prostatic cancer (PC) using prostate specific antigen (PSA) filter paper method was performed in an urban area of Kyoto in 1995. METHODS In the primary study, males more than the age of 55 years were examined by PSA (Delfia PSA kit) with blood samples on a filter paper. The cut-off values were set at 4 and 10 ng/ ml. Subjects whose PSA level ranged from 4...
BACKGROUND Heart failure (HF) patients are at risk for structural brain changes due to cerebral hypoperfusion. Past work shows obesity is linked with reduced cerebral blood flow and associated with brain atrophy in healthy individuals, although its effects on the brain in HF are unclear. This study examined the association among body mass index (BMI), cerebral perfusion, and brain volume in HF ...
We present a Size-Intensity Diagram, based on a gray-scale granulometry. For this we use a cylindrical structuring function with two varying parameters: the radius r and the height (or intensity) k. The measurement associated with this gray-scale granulometry is based on the volume measurement commonly used in the classical gray-scale granulometry. The proposed diagram is therefore a bidimensio...
Background and purpose: Today, due to the reduction of water resources, separation of gray water from domestic wastewater and its reuse has gained more interest. The aim of this study was to apply multi-layer filtration (MLF) for removal of nutrients from gray water. Materials and methods: This laboratory-scale study was carried out in 2.3-19.2 gr. COD / L. d organic loading rates (OLR) over a...
