We conducted in this paper an experimental study on BitTorrent (BT) download performance. Although BT has been widely deployed, many important features about it are not clear yet. For example, what parameter configuration is optimal for its download performance and to what extent is its incentive mechanism efficient in preventing free-riding. We focused our(More)
This study aimed to investigate the effect of combination of felodipine+puerarin on ACE2-Ang (1-7)-Mas axis, and to explore the protective effect of the combination against kidney in renovascular hypertensive rats. Goldblatt rats were randomly divided into 5 groups as follows: 4 groups which were treated with felodipine (Felo), puerarin (Pue), Felo+Pue, and(More)
Sea water samples were collected in the East China Sea in March and April, 2005, and three-dimensional fluorescence of dissolved organic matter was measured by fluorescence excitation-emission matrix spectroscopy. The position, number and intensity of fluorescence peak in the spectra and the relations of the peaks were analyzed to determine the type,(More)
OBJECTIVE To investigate surgical procedure and clinical effects for the treatment of patellofemoral osteoarthritis (PFOA) with arthroscopic patelloplasty and circumpatellar denervation. METHODS Totally 156 patients with PFOA (62 males and 94 females; aged from 45 to 61 years old with an average of 52) were treated from September 2011 and March 2013. The(More)
N-furoyl chitosan (NF-CS) and N-furoyl chitosan oligosaccharide (NF-COS) were prepared via acylation of chitosan and chitosan oligosaccharide. Their chemical structures and physical properties were characterized by Fourier transform infrared spectroscopy, (1)H NMR, X-ray diffraction, and elemental analysis. Results showed that the degrees of substitution of(More)
OBJECTIVE To explore the effect of puerarin combined with felodipine on the mRNA and protein expression of apelin and APJ in renal tissue of renovascular hypertensive rat. METHOD Sixty-two Sprague-Dawley rats were used, of which 8 rats were randomly chosen as sham-operation group. The remaining rats were made for the rat model with renovascular(More)
Molecular imprinted polymers (MIPs) were prepared through thermal polymerization by using quercetin as the template molecule, acrylamide (AA) as the functional monomer and ethylene glycol dimethacrylate (EDMA) as the cross-linker in the porogen of tetrahydrofuran (THF). The synthesized MIPs were identified by both Fourier transform infrared (FTIR) and(More)
OBJECTIVE Most comprehensive treatments for PBC include UDCA, combination of methotrexate (MTX), corticosteroids (COT), colchicine (COC) or bezafibrate (BEF), cyclosporin A (CYP), D-penicillamine (DPM), methotrexate (MTX), or azathioprine (AZP). Since the optimum treatment regimen remains inconclusive, we aimed to compare these therapies in terms of patient(More)
In this paper we propose a new method of Sybil attack detection in wireless sensor network (WSN) based on received signal strength indication (RSSI). This method establishes Jakes channel model by emulating real network space situation of WSN. At the same time, it judges Sybil attack from both the received signal's strength of nodes and the status messages(More)
OBJECTIVE To compare a full-automated software to quantify 3D transthoracic echocardiography namely, 3DE-HM (three-dimensional echocardiography HeartModel, Philips Healthcare) with the traditional manual quantitative method (3DE-manual) for assessing volumes of left atrial and ventricular volumes, and left ventricular ejection fraction (LVEF). METHODS 3D(More)
