Appropriate monochromatic illumination that is spatially uniform will ensure densitometry of stained polyacrylamide electrophoresis gels with high sensitivity and repeatability. The approach of using an array of LEDs as an illuminator has practical limitations. Here we describe an alternative method based on adapted liquid crystal display backlighting. By changing the fluorescent light source a...

tissue level myocardial perfusion is one of the most important prognostic factors after successful recanalisation of the occluded coronary artery in patients suffering acute st elevation myocardial infarction (stemi). the primary objective of the present study was to examine the relationship between videodensitometric myocardial perfusion parameters as assessed on coronary angiograms directly f...

pemphigus vulgaris (pv) is often complicated by osteoporosis. although corticosteroid therapy undoubtedly plays a causative role, inflammation associated with pv may also contribute to osteoporosis. this study was designed to determine the prevalence of osteoporosis in patients with pv before corticosteroid therapy and to compare these findings with those reported previously in healthy voluntee...

background : the liver is a vital organ that plays an important role in the metabolism of nutritional agents, drugs and hormones,synthesis of various proteins, coagulation factors and maintenance of hemostasis between calcium,and phosphorous. biochemical changes in the skeletal system such as osteopenia and pathologic fractures may follow hepatic failure. this researchevaluates metabolic bone c...

INTRODUCTION Osteoporosis is a disease characterized by a decrease in bone mineral density, making bones become less rigid, and therefore susceptible to fractures, either spontaneously or with force, which is lower than otherwise needed for healthy bones fractured. Nearly 10% of the world population and 30% of women after menopause, suffer from osteoporosis. Clinical assessment of osteoporosis ...

PURPOSE To observe the first 24-hour (h) outcomes of the small incision lenticule extraction procedure (SMILE) for myopia and myopic astigmatism. METHODS Fifty-three eyes (27 patients) scheduled for SMILE were followed immediately (0 h), 2, 4, 6, and 24 h after SMILE. Uncorrected visual acuity (UCVA), conjunctival congestion, pain level, and corneal edema, thickness, and densitometry were rec...

purpose: to evaluate densitometry of crystalline lens after cxl procedure in keratoconic patients. methods: in a quasi-experimental study three-dimensional lens densitometry was performed by pentacam scheimpflug camera at base line and 6 months later. subject group contained patients with diagnosed progressive keratoconus who underwent cxl surgery (n = 40). control group contained aged-matched ...
