TL;DR: The results suggest that the method of intermittent altitude hypoxia could make the pharyngeal tissue of mini pig remodel and change its muscular biomechanical structure into those similar to the performance of OSAS in human patients.

TL;DR: It is suggested that BMSCs could be induced to differentiate into hepatocytes and participate in the regeneration of liver in BALB/C male donor mouse.

TL;DR: The principles, development, characteristic, key technology and clinical application of different ultrasonic scalpels in the world are introduced, and the domestic application and future development of ultrasonic scalpel are prospected.

TL;DR: Through acoustic intensity analysis, the maximum improvement of SNR of ultrasonic image with coded excitation is deduced and guide lines to choose codes in ultrasonic imaging are introduced, including white noise, pseudo-random code, Golay code, Chirp and pseudo-chirp.

TL;DR: HIM (Healthcare integrating model) provides a 3-D scheme for the integration of medical information systems, which not only contains the three aspects of integration application vertically, but covers the whole medical area horizontally.

TL;DR: The basic conception of mutual information, the transform model, the insert value algorithm, the optimization algorithm and the strategy in computing mutual information are presented, which introduces some efficient methods for solving the problems in registration technique based on mutual information.

TL;DR: The results showed that sympathetic activity of the subjects enhanced after the simulated driving while parasympathetic activities decreased, and the sympathovagal balance was also improved, suggesting that the evaluation of autonomic activities by means of multi-variable synthetic effect analysis is scientific and objective.

TL;DR: The data suggest that diabetic patients and their NFDR from type 1 diabetic pedigrees had significantly higher AIP than did controls; AIP could be decreased by therapy with Acarbose in type 2 diabetic patients; Glimepiride may bring potential benefit to type 2 diabetes patients by influencing sdLDL.

TL;DR: A novel processing technique for the extraction of micro-calcification region of interest (MROI) in mammograms based on a three-step procedure, which can achieve a true positive rate as high as 89.7% with a false positive rates as low as 2.1%.

TL;DR: The potential harmfulness of nickel in medical metal materials and new trend on research and development are reviewed in this article, and both the advantage and the long term potential development of nickel-free medical stainless steels are also described on the basis of their own research work.

TL;DR: The experiment indicated that there was evident "window-effect" during the treatment by PEMFs, which is favorable to the treatment and prevention of osteoporosis.

TL;DR: It was concluded that shear stress can induce endothelial NO synthesis and caveolae plays a key role in shear Stress-induced eNOS activation.

TL;DR: An algorithm for recognizing the markers in human motion detection is proposed and the result of experiments shows that the algorithm can recognize the positions of the markers at a relatively higher accuracy and speed.

TL;DR: HPV 16 infection was relatively higher in the colorectal carcinoma and rare in the adjacent normal mucosa and Specimens expressing higher levels of HPV 16 E7 DNA were associated with lower Dukes stage and more distal location.

TL;DR: This study demonstrates that Hydroxyapatite nanoparticles could be used as gene carriers and show that the nanoparticles have excellent biocompatibility with cells.

TL;DR: The experimental results indicated that in the circumstances of size of laser doze D and scanning velocity V being fixed, the density of microstructure in bioceramics coating gradually degraded; with the increasement of power P, the pore rate of biocerramics gradually became high.

TL;DR: The test results suggest that the output values and optimal frequency of micropumps can be improved by changing the valve dimension, and the viewpoint that checkvalve micropump works only with low acting frequency is wrong.

TL;DR: A new technique, Empirical Mode Decomposition (EMD), for use in non-stationary and non-linear data processing, was introduced and some simulated signal, real ECG and RRI signals combined with Hilbert Transform method were analyzed.

TL;DR: A novel denoise method using independent component analysis (ICA) to remove the interference of ECG from sEMG recordings by a high-pass filter that kept the useful information as more as possible during ECG cancellation.

TL;DR: The results indicated that cardiomyocytes are susceptible to non-ionizing radiation, which is one of the most critical mechanisms to explain the athermal effects of electromagnetic radiation.

TL;DR: The data suggest that the malignant phenotype could be reversed by wild nm23-H1 gene in L9981 cells, a proven tumor metastasis suppressive gene.

TL;DR: The method to reconstruct an image sequence shot by a stationary camera was described and the result of the reconstruction process was a set of data that is kinematically consistent with the biomechanical model used.

TL;DR: In this paper, correlation dimension (D2) and approximate entropy (ApEn) of sleep EEG have been calculated and it is revealed that D2 does not come to be saturated when the embedding dimension increases, but the relative value of D2 can effectively distinguish different sleep stages.

TL;DR: The study indicate that the sintered bovine cancellous bone with beta-TCP type had certain intension, appropriate aperture, connective pore and credible biosecurity, it could be used clinically as bone graft material.

TL;DR: Triptolide may inhibit the proliferation and migration of endothelial cell by way of reducing the expression of u-PA and may conduce to the elucidation of the anti-angiogenic mechanism of triptolides.

TL;DR: Developments in understanding of interactions between blood and materials surfaces, especially the changes of plasma protein conformation structure and activation of platelets induced by biomaterials surfaces, are reviewed.

TL;DR: After the all-night sleep in six nights being monitored, the process of sleep is shown by EEG complexity and spectrum feature, and results indicate that the deeper the sleep, the smaller the EEG complexity of whole cortex.

TL;DR: The dynamic alteration of interleukin-8 protein and gene expression was up-regulation in the development of fatty streaks in hyperlipemia rabbit as well as in atherosclerotic lesions ofhyperlipemia rabbits with establishing model.

TL;DR: The system develooped on the basis of this experiment is of great significance to studying the measurement of complex-permittivities of high-loss biologic tissues by perturbational method.
