Mucin MUC4, which is encoded by the MUC4 gene, plays an important role in epithelial cell proliferation and differentiation. Aberrant MUC4 overexpression is associated with invasive tumor proliferation and poor outcome in epithelial cancers. Collectively, the existing evidence suggests that MUC4 has tumor-promoter functions. In this study, we performed a(More)
The purpose of this paper is to improve mel frequency cepstrum coefficients (MFCCs) for cough recognition. To highlight high energy, the most remarkable characteristic of cough sound, we propose a method of sub-band energy transformation to improve traditional MFCCs. This method enhances bands with high energy and ignores the ones with low energy according(More)
BACKGROUNDS Bone morphogenetic protein receptor type 2 (BMPR2) signaling is anti-inflammatory. Decreased BMPR2 expression was seen in lung tissue from chronic obstructive pulmonary disease (COPD) patients. METHODS The selected single nucleotide polymorphisms (SNPs) in BMPR2 were genotyped with polymerase chain reaction (PCR) ligase detection reaction. The(More)
Extracting the diaphragmatic electromyogram (EMG) signal is the key to manufacture the breathing machine in synchrony with patient. However, the diaphragmatic EMG signal is immerged in the electrocardiogram (ECG) signal. The mixed signals composed of EMG signal and ECG signal are obtained from the platform of EMG signal acquisition. Hence, extracting the(More)
Dynamic lung sound signal analysis and processing require synchronous multi-channel data acquisition system. In noninvasive and no pain lung sound diagnosis system, the highly accurate, synchronous and stable data acquisition system is the foundation of fellow-up work. In order to acquire the array data of lung sound, higher speed, reliability and(More)
