Bacteriorhodopsin and epsilon 15 bacteriophage were used as biological test specimens to evaluate the potential structural resolution with images captured from a 4k x 4k charge-coupled device (CCD) camera in a 300-kV electron cryomicroscope. The phase residuals computed from the bacteriorhodopsin CCD images taken at 84,000x effective magnification averaged 15.7 degrees out to 5.8-A resolution r...

The ejection fraction is one of the most widely used measurements of left ventricular systolic function. Angiographic measurement of ejection fraction is based on determination of roentgenographic magnification and calculation of end-diastolic and end-systolic volumes, assuming a prolated ellipse. Because it is simple and radiographic magnification may not have been determined, some laboratorie...

Gastric mucosa-associated lymphoid tissue lymphoma is uncommon and most patients have an indolent clinical course. The clinical presentation and endoscopic findings can be subtle and diagnosis can be missed on white light endoscopy. Magnifying endoscopy may help identify the abnormal microstructural and microvascular patterns, and target biopsies can be performed. We describe herein the case of...

Interaction of Chrysosporium sps. and Aspergillus sps. with aqueous AgNO3 was investigated for synthesis of silver nanoparticles. Biological reduction and extracellular synthesis of silver nanoparticles in 28 hour at 270C and pH 5.6 was done. The nanometallic dispersion was characterized by surface plasmon absorbance measuring at 424 – 530 nm for Ag nanop...

abstract background and aim: considering the widespread development of implants in dental treatment plans, linear measurements on panoramic radiography are of especial importance. in the present study we investigated the effect of head misalignment up to 15° around vertical and horizontal axes on the magnification rate of digital panoramic radiography in each part of upper and lower jaws. mater...
