BACKGROUND To describe the health related quality of life in a population sample of postmenopausal women over the age of 50 and resident in the city of Valencia (Spain), according to the presence/absence of osteoporosis and the severity of prevalent morphometric vertebral fractures. METHODS A cross-sectional age-stratified population-based sample of 804 postmenopausal women of 50 years of age...
Covalently closed relaxed SV40 DNA [SV40(I')] generated by polynucleotide ligase closure of nicked circular SV40 DNA was analyzed by agarose gel electrophoresis. The DNA can be resolved into a series of bands differing in superhelical density whose intensities are approximately symmetrical about a central most intense band. Densitometric analysis of the gel pattern has revealed that the distrib...
BACKGROUND Lung volume reduction (LVR) improves breathing mechanics by reducing hyperinflation. Lobar selection usually focuses on choosing the most destroyed emphysematous lobes as seen on an inspiratory CT scan. However, it has never been shown to what extent these densitometric CT parameters predict the least deflation of an individual lobe during expiration. The addition of expiratory CT an...
A simple and rapid method for separation and determination of meloxicam and its degradation products by thin-layer chromatography with densitometric detection in pharmaceutical preparations was described. The method employed TLC F254 plates as the stationary phase. The solvent system consisted of ethyl acetate : toluene : butylamine (2:2:1, v/v/v). Densitometric analysis was carried out in abso...
A rapid, sensitive, selective and robust quantitative densitometric high-performance thin-layer chromatographic method was developed and validated for separation and quantification of syringic acid (SYA) and kaempferol (KML) in the hydrolyzed extracts of Bergenia ciliata and Bergenia stracheyi. The separation was performed on silica gel 60F254 high-performance thin-layer chromatography plates u...
