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
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
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
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.

Chapter 13 - Nuclear magnetic resonance spectroscopy. In this chapter, students will be able to understand: Use the chemical shifts, splitting patterns, and integrations shown in a proton NMR spectrum to propose structures for possible compounds; use the number of peaks and their chemical shifts in a 13C NMR spectrum to determine the number of types of carbon atoms in the compound and what functional groups they might represent;...
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

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.

brain maturation, in newborns with congenital heart disease before they underwent
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....
