281. In Vivo T2 Relaxation Time Measurement with Echo-Time Averaging Full Text available with Trip Pro

In Vivo T2 Relaxation Time Measurement with Echo-Time Averaging The accuracy of metabolite concentrations measured using in vivo proton ((1) H) MRS is enhanced following correction for spin-spin (T2 ) relaxation effects. In addition, metabolite proton T2 relaxation times provide unique information regarding cellular environment and molecular mobility. Echo-time (TE) averaging (1) H MRS involves the collection and averaging of multiple TE steps, which greatly simplifies resulting spectra due (...) to the attenuation of spin-coupled and macromolecule resonances. Given the simplified spectral appearance and inherent metabolite T2 relaxation information, the aim of the present proof-of-concept study was to develop a novel data processing scheme to estimate metabolite T2 relaxation times from TE-averaged (1) H MRS data. Spectral simulations are used to validate the proposed TE-averaging methods for estimating methyl proton T2 relaxation times for N-acetyl aspartate, total creatine, and choline-containing

282. 19F Spin-lattice Relaxation of Perfluoropolyethers: Dependence on Temperature and Magnetic Field Strength (7.0-14.1T) Full Text available with Trip Pro

19F Spin-lattice Relaxation of Perfluoropolyethers: Dependence on Temperature and Magnetic Field Strength (7.0-14.1T) Fluorine ((19)F) MRI of perfluorocarbon-labeled cells has become a powerful technique to track the migration and accumulation of cells in living organisms. It is common to label cells for (19)F MRI with nanoemulsions of perfluoropolyethers that contain a large number of chemically equivalent fluorine atoms. Understanding the mechanisms of (19)F nuclear relaxation (...) , and in particular the spin-lattice relaxation of these molecules, is critical to improving experimental sensitivity. To date, the temperature and magnetic field strength dependence of spin-lattice relaxation rate constant (R1) for perfluoropolyethers has not been described in detail. In this study, we evaluated the R1 of linear perfluoropolyether (PFPE) and cyclic perfluoro-15-crown-5 ether (PCE) at three magnetic field strengths (7.0, 9.4, and 14.1T) and at temperatures ranging from 256-323K. Our results show

283. Image-based evaluation of contraction-relaxation kinetics of human-induced pluripotent stem cell-derived cardiomyocytes: Correlation and complementarity with extracellular electrophysiology. Full Text available with Trip Pro

Image-based evaluation of contraction-relaxation kinetics of human-induced pluripotent stem cell-derived cardiomyocytes: Correlation and complementarity with extracellular electrophysiology. In this study, we used high-speed video microscopy with motion vector analysis to investigate the contractile characteristics of hiPS-CM monolayer, in addition to further characterizing the motion with extracellular field potential (FP), traction force and the Ca(2+) transient. Results of our traction force (...) changes in the motion and field potential duration in response to verapamil (30-150nM), isoproterenol (0.1-10μM) and E-4031 (10-50nM). In addition, tetrodotoxin (3-30μM)-induced delay of sodium current was corresponded with the delay of the contraction onset of hiPS-CMs. These results indicate that the electrophysiological and functional behaviors of hiPS-CMs are quantitatively reflected in the contractile motion detected by this image-based technique. In the presence of 100nM E-4031, the occurrence

284. Evaluating the Uncertainty in Exchange Parameters Determined from Off-Resonance R1ρ Relaxation Dispersion for Systems in Fast Exchange Full Text available with Trip Pro

Evaluating the Uncertainty in Exchange Parameters Determined from Off-Resonance R1ρ Relaxation Dispersion for Systems in Fast Exchange Spin relaxation in the rotating frame (R1ρ) is a powerful NMR technique for characterizing fast microsecond timescale exchange processes directed toward short-lived excited states in biomolecules. At the limit of fast exchange, only k(ex)=k(1)+k(-1) and Φex=p(G)p(E)(Δω)(2) can be determined from R1ρ data limiting the ability to characterize the structure (...) and energetics of the excited state conformation. Here, we use simulations to examine the uncertainty with which exchange parameters can be determined for two state systems in intermediate-to-fast exchange using off-resonance R1ρ relaxation dispersion. R1ρ data computed by solving the Bloch-McConnell equations reveals small but significant asymmetry with respect to offset (R1ρ (ΔΩ)≠R1ρ (-ΔΩ)), which is a hallmark of slow-to-intermediate exchange, even under conditions of fast exchange for free precession

286. Stress-relaxation and tension relief system for immediate primary closure of large and huge soft tissue defects: an old-new concept: new concept for direct closure of large defects. Full Text available with Trip Pro

Stress-relaxation and tension relief system for immediate primary closure of large and huge soft tissue defects: an old-new concept: new concept for direct closure of large defects. Stress-relaxation is a well-established mechanism for laboratory skin stretching, with limited clinical application in conventional suturing techniques due to the inherent, concomitant induction of ischemia, necrosis and subsequent suture failure. Skin defects that cannot be primarily closed are a common difficulty (...) during reconstructive surgery. The TopClosure tension-relief system (TRS) is a novel device for wound closure closure, providing secured attachment to the skin through a wide area of attachment, in an adjustable manner, enabling primary closure of medium to large skin defects. The aim of this study was to evaluate the efficiency of the TopClosure TRS as a substitute for skin grafting and flaps for primary closure of large soft tissue defects by stress-relaxation. We present three demonstrative cases

291. Acupuncture and relaxation response for craving and anxiety reduction among military veterans in recovery from substance use disorder. (Abstract)

Acupuncture and relaxation response for craving and anxiety reduction among military veterans in recovery from substance use disorder. Substance use disorder (SUD) is a major health issue, especially among military veterans. We previously reported the effects of auricular acupuncture and the relaxation response (RR) on reducing craving and anxiety following 10-week interventions among veterans who were in recovery from SUDs. Our current analysis examines effects following each intervention (...) for analysis.Craving and anxiety levels decreased significantly following one session of acupuncture (-1.04, p=.0001; -8.83, p<.0001) or RR intervention (-.43, p=.02; -4.64, p=.03). The level of craving continued to drop with additional intervention sessions (regression coefficient b=-.10, p=.01, and b=-.10, p=.02 for acupuncture and RR groups, respectively). Number of daily practice days of RR-eliciting techniques is also associated with reduction in craving ratings (b=-.02, p=.008).Findings demonstrate the value

Effectiveness of Jaw Relaxation for Burn Dressing Pain: Randomized Clinical Trial. Patients hospitalized for burn injuries experience severe pain, both immediately after the injury and during daily therapeutic procedures such as dressing changes. Relaxation is increasingly suggested as a pain control technique that can be used by nurses in daily practice. Yet the effects of relaxation on burn pain are not clear. The aim of this study was to investigate whether jaw relaxation will decrease pain (...) was seen between mean pain intensity scores in the experimental and control groups after dressing (p = .676). Regarding the ineffectiveness of jaw relaxation for pain intensity of burn dressing, future studies are suggested to concentrate on longer durations of relaxation time and continuing the procedure in dressing room. Simultaneous study of the effect of this technique on residual, breakthrough, and procedural burn pain is also recommended. Copyright © 2014 American Society for Pain Management

296. A study of the effect of relaxing music on heart rate recovery after exercise among healthy students. (Abstract)

A study of the effect of relaxing music on heart rate recovery after exercise among healthy students. Music has been employed in various clinical settings to reduce anxiety. However, meta-analysis has shown music to have little influence on haemodynamic parameters. This study aimed at investigating the effect of relaxing music on heart rate recovery after exercise.Twenty-three student volunteers underwent treadmill exercise and were assessed for heart rate recovery and saliva analysis (...) ; comparing exposure to sedative music with exposure to silence during the recovery period immediately following exercise.No differences were found between music and non-music exposure regarding: heart rate recovery, resting pulse rate, and salivary cortisol. Music was no different to silence in affecting these physiological measures, which are all associated with anxiety.Relaxing music unaccompanied by meditation techniques or other such interventions may not have a major role in reducing anxiety
