BACKGROUND Coronary artery lumen volume may potentially have several advantages over the commonly used variables, such as percent stenosis or minimal lumen diameter, in the assessment of coronary artery disease. The goal of this study is to validate a quantitative assessment of lumen volume using a video densitometry technique. METHODS AND RESULTS Coronary arteriography was performed in 9 swi...

Background: Daidzin (glycosidic isoflavone) bioconversion into daidzein (aglyconic increases its bioactivity. This can be carried out using fermentation, a fungus that has been widely used for making tempeh in Indonesia, Aspergillus oryzae. Objective: study aimed to validate the method of analysis and determine content A. oryzae-fermented edamame TLC densitometry. Method: Daidzein determination...

osteoporosis diagnosis is usually based on examination of the hip bone and vertebrae density; however, the radius bone has gained attention recently in terms of feasibility and accessibility as it is done by portable devices with proper precision. this study aims to compare hip and spine density with radius, knowing whether radius may be an appropriate alternative for osteoporosis diagnosis. 12...

OBJECTIVE To assess doctors' and patients' views about a district general hospital bone densitometry service and to examine existing practice to influence future provision. DESIGN Three postal surveys: (a) of doctors potentially using the service, (b) of patients undergoing a bone densitometry test during a six month period, and (c) of the referring doctors of the patients undergoing the test...

patients and methods in this cross-sectional study, we evaluated all patients referred to a single rheumatology clinic for bone mineral density measurements from 2009 to 2010. all patients who had bone mineral density measurements taken from the hip, lumbar spine, forearm, and whole body were enrolled in the study. standard bone mineral density measurements were performed using a dual energy x-...

a simple, accurate and rapid high performance thin layer chromatography (hptlc)-densitometric method was developed for separation and determination of cetirizine (cet) as a long acting antihistamine and montelukast (mon) as an antileukotriene in pharmaceutical dosage forms. the compounds were separated on silica gel 60 f254 hptlc plates using a mixture of ethyl acetate : methanol : ammonia solu...
