    Extractions: - Biomedical Nuclear Magnetic Resonance - Director: Jens Frahm development and application of spatially resolved NMR; noninvasive neurobiology; human neuroscience; structural, metabolic, and functional studies; brain disorders in childhood; animal studies of acute stoke; functional mapping of neuronal activation; cognitive information processing in humans The application of spatially resolved nuclear magnetic resonance (NMR) in the life sciences is unique as it provides noninvasive insights into the anatomy, metabolism, and function of intact human (and animal) organ systems. Magnetic resonance imaging (MRI) and localized spectroscopy (MRS) allow us to raise questions ranging from basic biologic research to medical diagnosis, and to investigate humans, animals, perfused organs, tissue extracts, and cell suspensions in comparable experiments. It is our primary aim to further pertinent approaches for a better understanding of the functioning human brain under physiologic and pathologic conditions. Subsequent to the development of a fast scan MRI principle - a scientific, clinical, and economic breakthrough - current MRS projects extend our questions to human brain metabolism and its pathologic alterations, as well as to the relations between structure, metabolism, and function. Figure 1 shows typical proton NMR spectra of major metabolites in gray and white matter of a healthy human subject.

    Extractions: Application and development of NMR methodology and theory The nuclear magnetic resonance phenomenon underlies a large and growing family of experimental techniques for investigating the structure, dynamics and interactions of condensed matter on length scales from the molecular to the macroscopic, and on time scales from picoseconds to hours and longer. Forty years ago, when NMR had become an established method in chemical research, about 2,000 papers had been published in the NMR field. Today, a similar number of NMR papers are added to the literature every five weeks in fields ranging from solid-state physics to neurophysiology. No other physical probe of molecular behavior can rival NMR in range of applications and potential for development. During the past two decades, the biomolecular and medical applications of NMR have been transformed by major methodological breakthroughs and today they dominate the field. NMR is used in one way or another in the majority of the biophysical research projects undertaken in the Department. We use NMR to determine the three-dimensional structures of proteins in solution, to characterize conformational dynamics essential for protein function, and to study the interactions of proteins and nucleic acids with other molecules, including water, co-solvents and ions, functional ligands and other biomolecules.

    Extractions: Nuclear Magnetic Resonance Structural Biology The Nuclear Magnetic Resonance (NMR) Structural Biology Facility carries out studies on a diverse array of biologically relevant systems in order to obtain detailed structural information. Analysis of such systems under physiological solution conditions can generate three-dimensional structure data and molecular flexibility/rigidity information and allows the detailed investigation of exactly how biomolecules carry out their designated function. Additionally, appropriate interactions between such molecules can be conveniently studied. The NMR Structural Biology Facility can be used to assist in the work of research groups of the Wadsworth Center. These studies proceed as collaborative arrangements with staff members of the NMR group. Initial questions concerning the feasibility of projects for NMR study should be directed to the facility's Director. It is anticipated that many appropriate projects will develop into work fundable by external agencies. Complete involvement at all stages of investigation by collaborators is encouraged under the supervision on NMR group members.

    Extractions: News By Ricki Lewis Prions have been a tough sell. Against a backdrop of the "DNA to RNA to protein" credo, the idea that the same amino acid sequence could exist in multiple forms, both normal and deranged, seemed like heresy. But since Stanley Prusiner , a professor of neurology, virology, and biochemistry at the University of California, San Francisco (UCSF), named the agent that causes the transmissible spongiform encephalopathies (TSEs) "proteinaceous infectious particles" in 1982, evidence has been steadily accumulating that these prion proteins can indeed set up a deadly chain reaction that renders the brains of 85 mammalian species similar in appearance to Swiss cheese. Yet despite the mounting evidence, many demonstrations of prion action have been inferred, indirect, or incomplete. A view of how the same molecule can take on different guises has been lackinguntil now. Thomas James , chairman of the department of pharmaceutical chemistry at UCSF, with Prusiner and others, has identified the changeling part of the prion protein (PrP).

    Extractions: Next: 8.8.1 Relaxation Mechanisms Up: 8 Experimental Techniques Previous: 8.7 Infrared Dichroism In the presence of a magnetic field, nuclei with non-zero nuclear spin have a discrete number of possible energy levels. Application of a radiofrequency pulse of the correct frequency can stimulate the nuclei into a higher energy state - the resonance condition. Nuclei with even atomic number, Z , and even atomic weight, A , possess zero spin; if A is even and Z odd the spin is an integer value; all other conditions result in half-integer values of spin. The spin is measured in units of h /2 where h is Planck's constant. The spin is characterised by the spin quantum number I = 1/2, 1, /2, 2, 5/2, ...etc. Thus H, C and F all have I = 1/2, Li, D and N have I = 1, and Na and Cl have I = 3/2 . C and O both have zero spin. The number of energy levels is (2 I +1), thus nuclei of spin 1/2 have two possible energy levels and align either parallel or anti-parallel to the applied magnetic field; I = 1 results in three possible energy levels. The magnetic moment

    http://rpl.pnl.gov/cap_nmr.stm
    
    Extractions: Related Links Nuclear magnetic resonance (NMR) methods have been exploited by chemists to study innumerable chemical systems. The maturity of the techniques is such that they are routinely used in the study of organic, organometallic, and coordination compounds; including very complex molecules such as proteins, enzymes, and DNA. Indeed, magnetic resonance is used to image humans for medical diagnostics (MRI). Yet, capabilities to study radioactive materials by magnetic resonance techniques are very limited. With this in mind, PNNL researchers set out to establish a facility specifically designed for NMR examination of radioactive materials. This effort has culminated in the RPL Radiological NMR Laboratory. This facility houses two NMR spectrometers-a 300 MHz spectrometer and a variable field spectrometer. The 300 MHz NMR spectrometer is built around an Oxford Instruments 300 MHz superconducting magnet. Currently a two-channel, 5 mm MAS probe for solids and a two-channel 10 mm liquids probe are available for work with high dose radioactive materials. Both probes have one broadband channel and one proton-decoupling channel. The facility was designed for investigation of radioactive materials in the environment, radioactive tank waste, Pu bearing materials, and other DOE mission active areas as well as fundamental studies of actinide metal salts.

    Biomolecular Structure Analysis by nuclear magnetic resonance. David E.Wemmer, Lawrence Berkeley National Laboratory. Research Objectives.  
    http://www.nersc.gov/research/annrep98/wemmer.html
    
    Extractions: Biological and Environmental Research David E. Wemmer, Lawrence Berkeley National Laboratory The focus of our work is to understand structure-function relationships in biomolecules and their complexes by applying methods of modern multidimensional nuclear magnetic resonance (NMR). There are two major stages in the analysis of NMR data which rely heavily on computation. The first is optimized transformation of the time domain NMR data into frequency dimensions. To extend resolution, this transformation uses linear prediction or maximum entropy analysis, followed by Fourier transformation. Artifacts are removed from the data using iterative modeling of various sorts. The second stage of the analysis is in conversion of NMR-derived structural restraints, together with knowledge of the covalent structure of the molecule, into sets of coordinates (models) that are consistent with all experimental observations. This can be done through molecular-dynamics calculations in either Cartesian or internal angle spaces. These models are analyzed to determine the structure-function relationships of interest. Time allocated in the past year was used to explore both the data analysis and structure refinement steps. Unfortunately, the analysis program PROSA, though functional on other supercomputers, could not load experimental data when run on the Cray C90. However, the real-space refinement program AMBER was run to analyze the structure of an aptamer DNA (one found through an in vitro selection for arginine binding) in complex with its target. The results indicate a complex folded structure and demonstrate clear structural changes upon binding.

100. Nuclear Magnetic Resonance
     nuclear magnetic resonance (NMR). nuclear magnetic resonance is a radiofrequencyspectroscopy which measures the size of these splittings.  
     http://www.phy.mtu.edu/~suits/NMR.html
     
     Extractions: Small splittings in the energy levels of nuclei can occur in the presence of a magnetic field. Nuclear Magnetic Resonance is a radiofrequency spectroscopy which measures the size of these splittings. Typical splittings correspond to frequencies of 10 to 100 MHz, in contrast to optical spectroscopy where the frequencies are measured in terahertz (10 Hz or 1 million MHz). The most common nucleus used for NMR is the hydrogen nucleus. This is not only because hydrogen is present in many important compounds (such as all organic compounds and water) but also hydrogen is one of the easiest nuclei to observe using NMR. Most of the energy level splitting observed is due to the Zeeman interaction between the nuclear magnetic dipole moment and an externally applied magnetic field. If this were the only effect, then NMR would not be of great use since all compounds would respond at the same frequency. However, small shifts in the splittings occur from compound to compound making NMR a sensitve method to look at the molecular structure at a microscopic level. In the best cases, shifts as small as a few Hz can be observed. The most commonly observed frequency shifts are typically measured in parts per million (ppm). Thus, for example, a 10 ppm shift for a 100 MHz splitting would correspond to 1000 Hz = 1 kHz. Back
