Purpose The purpose of this study was to clarify correlations between corneal deformation parameters measured with a dynamic Scheimpflug analyzer and baseline factors such as axial length, intraocular pressure (IOP), age, central corneal thickness (CCT), and corneal curvature. Methods Ninety-six eyes of 96 healthy subjects (mean 55.2 ± 16.1 years of age) were examined using a dynamic Scheimpf...

Using a simple filtration method, red cell deformability was measured in healthy control subjects and in patients with peripheral vascular disease. Impaired red cell deformability was demonstrated in patients with rest pain or gangrene and in patients with intermittent claudication. An improvement in red cell deformability was demonstrated after successful reconstructive vascular surgery in bot...

One of the main issues in design bases and foundations on water-saturated soils conditions possible seismic impacts is geotechnical substantiation possibil-ity construction. Among influencing factors, one can single out assessment ability sandy soil to resist vibration liquefaction. The paper presents re-sults studying behavior samples under triaxial cyclic loading, which equivalent strength ac...

The biophysical properties of the human red blood cell (RBC) permit large deformations required for passage through narrow capillaries and spleen sinusoids. Several pathologic conditions alter RBC deformability that can result in abnormal circulation behavior. In the present work, altered RBC deformability caused by invading Plasmodium falciparum parasites, which are responsible for the disease...

This research investigates the behavior of square concrete columns externally wrapped by low-cost and easily available fiber rope reinforced polymer (FRRP) composites. study mainly aims to explore axial stress-strain relationships FRRP-confined columns. Another objective is assess suitable predictive models for ultimate strength strain A total 60 were cast, strengthened, tested under compressio...

PURPOSE OF THE STUDY To determine the effects of choline on red blood cell membrane properties and NO metabolism. MATERIAL AND METHODS Aliquots of venous blood from eleven healthy subjects were incubated in vitro with choline concentrations 10(-10) to 10(-3) M. The following parameters were determined: erythrocyte deformability, aggregation and membrane lipid fluidity, plasma K+, Na+, Ca2+, t...
