magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...
the years 1895 to 1898 were momentous for their impact on health and human well beings. first, wilhelm roentgen noted a glowing fluorescent screen, caused by invisible rays. this event subsequently led to the discovery of x-rays in 1895, and thus the birth of the “atomic age”. next becquerel’s investigations of these mysterious rays led to his experiments with uranium salt crystals. he thought ...
Introduction: Microdosimetry is a fundamental method that studies the nature of energy transfer in micron volumes in the particular biological cells. In a biological target, the amount of ionization does not indicate the magnitude of biological radiation-induced damage. However, the severity of biological harm depends strongly on the amount of the linear energy transfer along t...
aptamers define a new interesting class of receptor molecules with capability of binding to potentially any kind of molecules of interest. structurally, they are composed of nucleic acids (rna, dna or a mixture of both) with high specificity and affinity to amino acids, drugs, proteins and other molecules. apatmers are isolated from complex libraries of synthetic nucleic acids against the desir...
