Quantitative measurement of creatine content in skeletal muscle using /sup 1/H-MRS

IEEE Transactions on Magnetics, 2005

We obtained /sup 1/H magnetic resonance spectra of skeletal muscles, with and without atrophy, and quantitatively evaluated the content of creatine in the muscles. Wister rats at nine weeks old were subjected to sciatic nerve transection of the left hindlimb which caused neurogenic muscular atrophy at the left gastrocnemius muscle. The spectra were acquired from a 2/spl times/2/spl times/2-mm/sup 3/ ...

  • Quantitative measurement of creatine content in skeletal muscle using /sup 1/H-MRS

    We obtained /sup 1/H magnetic resonance spectra of skeletal muscles, with and without atrophy, and quantitatively evaluated the content of creatine in the muscles. Wister rats at nine weeks old were subjected to sciatic nerve transection of the left hindlimb which caused neurogenic muscular atrophy at the left gastrocnemius muscle. The spectra were acquired from a 2/spl times/2/spl times/2-mm/sup 3/ voxel located on the left gastrocnemius muscle with arrayed repetition times (TR) and echo times (TE). The signal intensities and the relaxation times of water and creatine were estimated by fitting a model equation to the measured spectra. The content of creatine was estimated from the signal intensities, the relaxation times, and the content of water. There was no significant difference in the relaxation times of water and creatine between the denervated group and the control group. The water content of the denervated group was significantly smaller than that of the control group (p<0.01). The creatine content of the denervated group was smaller than that of the control group, though the difference was not statistically significant. This method is useful for quantifying the creatine content on the order of 10/sup -3/ mol/kg.

  • Automated quantification of retinal nerve fiber layer atrophy in fundus photograph

    Quantitative analysis of the retinal nerve fiber layer (RNFL) defect is prerequisite in the early detection and management of glaucoma. A new automatic quantification method to evaluate the degree of RNLF defect has been proposed in this paper. Simple image processing technique is applied to locate optic disc and intensity of the pixels around optic disc is plotted. The area with RNFL defect can be easily determined by comparing the intensity plot of the RNFL and the first derivative of the intensity plot. Through analysis of the plot, thickness of RNFL also can be postulated.

  • Sensibility Assessment For User Interface And Training Program Of An Upper-Limb Rehabilitation Robot, D-SEMUL

    Upper-limb rehabilitation training for hemiplegic patients has been primarily conducted by human therapists, and, hence, their use of training methods and conditions strongly depends on their expertise. The force control and motion sensing functions of rehabilitation robots are expected to be used for the qualitative training/assessment in the next-generation computerized rehabilitation. In this study, we developed a desktop rehabilitation robot for upper limbs (D-SEMUL). In addition, we also assessed the usability of its user interface and the affinity (acceptance) of the training program with a questionnaire for elderly hemiplegic/non-hemiplegic participants (nine hemiplegic, five males and four females and seven non-hemiplegic, two males and five females). The results indicated that the touchscreen is acceptable for the user interface, and the background music used significantly affects the affinity of the program.

  • Development of a system for finding best electrode position for myoelectric hand control for derating of upper limb amputee

    The artificial hand controlled in myoelectric signal is referred to the myoelectric hand. The myoelectric hand controls a switching action of terminal device by changing the voltage of EMG signal generated by the contraction of the muscle remaining upper limb stump. Two signals are necessary to control of switching action. It takes a long time to determine the best point where EMG signal picked up. The aim of this study is the development of a system for finding best electrode position to control a myoelectric hand for derating of upper limb amputee. We developed an electrode position finding system by using "a band-type multi-electrode" and confirmed validity of this system.

  • The role of ERK in phasic and tonic contractile responses in rat femoral arteries after hindlimb unloading

    The present study tested the hypothesis that the role of ERK in phasic and tonic contractile responses is declined by hindlimb unloading (HU) in rat femoral arteries. Male Wistar rats were randomised into HU and control group (n=7). After 14d, the femoral arteries were isolated and cut into 3-mm ring segments. In the absence or presence of PD98059(MEK inhibitor), contractile response to NE(10muM) was measured in Krebs solution in a tissue bath at 37degC, isometric tension were recorded with Powerlab system. The area under curve (AUC), phasic and tonic contractile responses between two groups were compared. After 14d-HU, the AUC, phasic and tonic NE-induced contractile responses were declined compared with controls. PD98059 did not affect the AUC in arteries from HU, but significantly decreased the AUC in arteries from control (100plusmn7.1% vs. 61.18plusmn11.3%, P&lt;0.05). In contrast to control, the inhibitory ratio of PD98059 was significantly lower in phasic (7.42plusmn3.24% vs. 33.59plusmn9.19%, P=0.0198) and tonic (26.93plusmn3.78% vs. 46.75plusmn5.67%, P=0.0131) contractile responses of HU group. Moreover, the inhibitory ratio of PD98059 wasn't significantly different between the phasic and tonic contractile responses in control group (P=0.2464). But for HU group, the difference was statistically significant (P=0.002). We demonstrated that the role of ERK was declined in both phasic and tonic contractile responses in rat femoral arteries after hindlimb unloading. Simulated microgravity induced by HU may attenuate the contractile responses of femoral arteries by inhibiting the role of ERK in thick and thin filament regulatory pathways

  • Using deep learning for robustness to parapapillary atrophy in optic disc segmentation

    Optic Disc (OD) segmentation from retinal fundus images is important for many applications such as detecting other optic structures and early detection of glaucoma. One of the major problems in segmenting OD is the presence of Para- papillary Atrophy (PPA) which in many cases looks similar to the OD. Researchers have used many different features to distinguish between PPA and OD, however each of these features has some limitation or the other. In this paper, we propose to use a deep neural network for OD segmentation which can learn features to distinguish PPA from OD. Using simple image intensity based features, the proposed method has the least mean overlapping error (9.7%) among the state-of-the-art works for OD segmentation in fundus images with PPA.
