Red blood cells (RBCs) present unique reversible shape deformability, essential for both function and survival, resulting notably in cell membrane fluctuations (CMF). These CMF have been subject of many studies in order to obtain a better understanding of these remarkable biomechanical membrane properties altered in some pathological states including blood diseases. In particular the discussion...

BACKGROUND PET reconstruction incorporating spatially variant 3D Point Spread Function (PSF) improves contrast and image resolution. "Cardiac Motion Frozen" (CMF) processing eliminates the influence of cardiac motion in static summed images. We have evaluated the combined use of CMF- and PSF-based reconstruction for high-resolution cardiac PET. METHODS Static and 16-bin ECG-gated images of 20...

BACKGROUND Moderate differences in efficacy between adjuvant chemotherapy regimens for breast cancer are plausible, and could affect treatment choices. We sought any such differences. METHODS We undertook individual-patient-data meta-analyses of the randomised trials comparing: any taxane-plus-anthracycline-based regimen versus the same, or more, non-taxane chemotherapy (n=44,000); one anthra...

objective(s) in the present study, the differences in the relaxant effects of aqueous, ethyl acetate and n-butanol fractions of rosa damascena on tracheal smooth muscle of guinea pigs were examined. materials and methods the relaxant effects of three cumulative concentrations of each fraction (0.1, 0.2 and 0.4 g%) in comparison with saline and three cumulative concentrations of theophylline (0....

Cloud impacts on the transfer of Ultraviolet (UV) radiation through the atmosphere can be assessed using a cloud modification factor (CMF). The total global solar irradiation has proven to be a solid basis to derive CMF’s for the UV radiation (UV CMF). Total global irradiance is frequently measured and forecasted by numerical weather predic5 tion systems. Its advantage compared to for instance ...

Cell membrane fluctuations (CMF) of human erythrocytes, measured by point dark field microscopy, were shown to depend, to a large extent, on intracellular MgATP (Levin, S.V., and R. Korenstein. 1991. Biophys. J. 60:733-737). The present study extends that investigation and associates CMF with F-actin's ATPase activity. MgATP was found to reconstitute CMF in red blood cell (RBC) ghosts and RBC s...

Three Gram-negative bacterial strains (Cmf 17.2T, Rd 20.33 and Cmf 18.22T) isolated from reared clams in Galicia were subjected to a taxonomic study, based on genetic and phenotypic characterization. Analysis of the 16S rRNA gene allowed the identification of the strains as members of the genus Marinomonas, sharing the highest similarity with Marinomonas aquimarina CECT 5080T (97.8 %-98.5 % 16S...

Background: Congenital malformations (CMF) are third most common cause of perinatal mortality in India making their prediction and prevention highly eminent. The present study was designed to analyze the frequency, distribution and patterns of CMF among babies born in a teaching hospital in Punjab, along-with factors contributing towards their occurrence. Methods: This was a prospective study i...

INTRODUCTION Non-battle injuries (NBIs) can be a source of significant resource utilization for the armed forces in a deployed setting. While the incidence and severity of craniomaxillofacial (CMF) battle injuries (BIs) have reportedly increased in the ongoing U.S. military conflicts in Iraq and Afghanistan, the prevalence and the nature of NBIs are not well described. MATERIAL AND METHODS Th...
