Glioma is a highly invasive, rapidly spreading form of brain cancer that is resistant to surgical and medical treatment. The recent progresses made in intracellular and ion channels of glioma cells provide a potential new approach for biochemical therapy of brain tumor. In this paper, we reviewed clinical data on chemotherapy by temozolomide and results(More)
Empirical Mode Decomposition (EMD) is an effective, non-linear and non-stationary data analysis method, which can decompose the original signal into several intrinsic mode functions(IMFs). However the frequency resolution of EMD has not been thoroughly investigated so far. In this paper a signal which contains two different frequency components was do(More)
First, the false peak of Burg Spectrum estimation is introduced. In this paper, a new method of eliminating false peak based on Empirical Mode Decomposition is proposed. Secondly, this new method is used in the Line spectrum analysis of ship radiated noise simulation signal. Compared with traditional Linear Spectrum analysis, it is a better method for(More)
Hilbert-Huang Transform(HHT) is widely used in extracting the instantaneous characteristics of signals. If using Hilbert Transform to deal with signals, the signals must Satisfy certain conditions, or else there will be errors in extracting the instantaneous characteristics of general signals. To solve this problem, a new method was proposed which combines(More)
It is greatly significant to detect harmonic accurately and effectively for improving the quality of electric energy in the power system. Actually, much noise exists in signal besides harmonics, inter-harmonics, so the key is how to detect harmonic signals from the complex power system. According to the analysis of harmonic and noise, a new method is(More)
Purpose: To investigate the radiolabeling of E-B5, a monoclonal antibody against Pro-GastrinReleasing Peptide(31-98)by Iodine and study the stability and immunoreactivity of I-E-B5. To determine the in vivo biodistribution of I-E-B5 in normal Kunming mouse and small cell lung cancerbearing nude mouse models(SCLC mouse model) to study the pharmacokinetics of(More)
BACKGROUND We previously reported that iodine-131((131)I)-labeled anti-pro-gastrin-releasing peptide (ProGRP(31-98)) monoclonal antibody D-D3 could selectively accumulate in the tumor sites of nude mice bearing small cell lung cancer (SCLC) xenografts. However, (131)I-D-D3 was cleared slowly from the body, and the best radioimmunoimaging time for SCLC was(More)
The empirical mode decomposition (EMD) was recently proposed as a new time-frequency analysis tool for non-stationary and non-linear signals. Firstly, In this paper a new signal analysis method of adaptive filter-EMD-LMS is introduced. Secondly, spectrum analysis of simulated signals are used based on EMD-LMS. Compared with traditional spectrum analysis(More)
OBJECTIVE To evaluate the diagnostic values of (99m)TcO(-)(4) thyroid imaging plus ultrasonography in the differentiation of benign and malignant thyroid nodules. METHODS (99m)TcO(-)(4) thyroid imaging and ultrasonography were performed for 114 patients with 125 thyroid nodules. And the examination results were compared with the post-operative(More)
