Ultrasound in Medicine and Biology
To assess the comparability of ultrasonographic (US) subcutaneous fat thickness (SFT) measurements in comparison with computed tomography (CT) at reference points (RPs) representative of HIV related adipose redistribution syndrome (HARS) in patients treated with antiretrovirals. US and CT measurements were compared in nine patients with clinical reports of HARS. We obtained the best resolution ...
متن کاملIsoenzymes in Biology and Medicine
formidable problems. Much of the value of the analysis may be lost in the synthesis. For example, in his effort to deal comprehensively yet concisely with similar but not identical investigations the author may create such monsters as: Allegedly, it is possible to induce phenomenon X, by administration of substance Y in the rabbit (1-3) but not in the rat (3-5); however, these claims have been ...
متن کاملMicrofabrication in biology and medicine.
Microfabrication uses integrated-circuit manufacturing technology supplemented by its own processes to create objects with dimensions in the range of micrometers to millimeters. These objects can have miniature moving parts, stationary structures, or both. Microfabrication has been used for many applications in biology and medicine. These applications fall into four domains: tools for molecular...
متن کاملLiposomes in biology and medicine.
Drug delivery systems (DDS) have become important tools for the specific delivery of a large number of drug molecules. Since their discovery in the 1960s liposomes were recognized as models to study biological membranes and as versatile DDS of both hydrophilic and lipophilic molecules. Liposomes--nanosized unilamellar phospholipid bilayer vesicles--undoubtedly represent the most extensively stu...
متن کاملFractals in biology and medicine.
Our purpose is to describe some recent progress in applying fractal concepts to systems of relevance to biology and medicine. We review several biological systems characterized by fractal geometry, with a particular focus on the long-range power-law correlations found recently in DNA sequences containing noncoding material. Furthermore, we discuss the finding that the exponent alpha quantifying...
