  • Both hypoxia and hyperoxia, deregulating the oxidative balance, may play a role in the pathology of neurodegenerative disorders underlain by cerebral ischemia. In the present study, quantitative proton magnetic resonance spectroscopy was used to evaluate regional metabolic alterations, following a 24-hour hypoxic or hyperoxic exposure on the background of ischemic brain insult, in two

  • uclear magnetic resonance spectroscopy can now be used to investigate the biochemical energetics of human tissues and organs noninvasively. The method already has increased our understanding of some muscle diseases, has provided information from muscle metabolism about whole-body functions, control, and hormonal status, has helped in the elucidation of hitherto unrecognized causes of disease, and yielded new ideas about the control of bioenergetics in vivo. Studies on the biochemistry of human brain, liver, heart, and kidney are just beginning.

  • NMR is an experiment in which the resonance frequencies of nuclear magnetic systems are investigated. NMR always employs some form of magnetic field (usually a strong externally applied field B0) NMR is a form of both absorption and emission spectroscopy, in which resonant radiation is absorbed by an ensemble of nuclei in a sample, a process causing detectable emissions via a magnetically induced electromotive force.

  • Magnetic resonance spectroscopy (MRS), unlike conventional magnetic resonance imaging (MRI), provides information on the brain’s chemical environment (rather than neuroanatomical structure) and the data are most commonly presented as line spectra. This capacity for determining brain metabolite concentrations provides the basis for clinical investigation of, and differentiation between, neurological and neurosurgical conditions.

  • In the Biomedical Applications of Biophysics, Volume 3 of the Handbook of Modern Biophysics, the authors have added to the topics introduced in Volume 1, Fundamental Concepts in Biophysics. These additional topics help trace the broad field of biophysics. Patrice Koehl starts the book with an introduction to protein structure prediction based on energetics, homology modeling, and ab-initio calculations. Dickey and Faller follow with a “how-to approach” to model biomembranes.

  • Sedation is the important factor in comfort of brain trauma patients. Insuffient sedation causes hypertension, tachycardia, hypoxia, hypercapnia and uncomfortable with ventilator. On the other hand excess sedation causes hypotansion, bradycardia, coma, respiratory depresion, ileus, renal insufficiency, veinous stasis and immunosupression. For the patients in the critical care unit firstly nonpharmacological method should be experinced for sedation. The patients should be frequently oriented.

  • Since the advent of magnetic resonance (MR) imaging, systems with amagnetic field intensity of 1.5 tesla (T) have been deemed the gold standard for different clinical applications in all body areas. Ongoing advances in hardware and software have made theseMRsystems increasingly compact, powerful and versatile, leading to the development of higher magnetic field strength MRsystems (3.0 T) for use in clinical practice and for research purposes. As usually occurs with a new technology, 3.0 T MR imaging units will probably follow the same development trends in the years to come....

  • Scientists have long relied on the power of imaging techniques to help them see things invisible to the naked eye and thus advance scientific knowledge. In medicine, X-ray imaging and magnetic resonance imaging (MRI) have added a level of insight beyond traditional lab tests into the workings of the human body and identification of disease at its earliest stages. Microscopy, which has been in use since the sixteenth century, is now powerful enough to detect, identify, track, and manipulate single molecules on surfaces, in solutions, and even inside living cells....

  • Quercetin 2,3-dioxygenase (2,3QD) is a copper-containing dioxygenase that catalyses the oxidation of the flavonol quercetin to 2-protocatechuoylphloroglucinol carboxylic acid with concomitant production of carbon monoxide. In contrast to iron dioxygenases, very little is known about copper dioxygenases. We have characterized 2,3QD from the fungus Aspergillus japonicus by electron paramagnetic resonance spectroscopy (EPR). At pH 6.0, 2,3QD shows a mixture of two EPR species. The major form has parameters typical of type 2 Cu sites (g// ¼ 2.330, A// ¼ 13.

  • Congenital heart disease in newborns is associated with global impairment in development. We characterized brain metabolism and microstructure, as measures of brain maturation, in newborns with congenital heart disease before they underwent heart surgery. Methods We studied 41 term newborns with congenital heart disease — 29 who had transposition of the great arteries and 12 who had single-ventricle physiology — with the use of magnetic resonance imaging (MRI), magnetic resonance spectroscopy (MRS), and diffusion tensor imaging (DTI) before cardiac surgery....
