White matter (WM) lesions are the classic pathological hallmarks of multiple sclerosis (MS). However, MRI-based WM lesion load shows relatively poor correlation with functional outcome, resulting in the "clinico-radiological paradox" of MS. Unlike lesion based measures, volumetric MRI assessment of brain atrophy shows a strong correlation with functional(More)
BACKGROUND Mechanical unloading of the heart results in atrophic remodeling. In skeletal muscle, atrophy is associated with inactivation of the mammalian target of rapamycin (mTOR) pathway and upregulation of critical components of the ubiquitin proteosome proteolytic (UPP) pathway. The hypothesis is that mechanical unloading of the mammalian heart has(More)
Advanced MRI studies demonstrated several diffuse non-lesional features in multiple sclerosis, including changes detectable in gray matter areas. Standard T2 weighted MRI scans of deep gray matter structures, including the thalamus, caudate, putamen, dentate nuclei often demonstrate hypointensity. T2 hypointensity has been shown to correlate with cognitive,(More)
Joint beamforming microphone arrays and multi-channel acoustic echo cancellation (AEC) can be ef£ciently applied for hands-free speech communication. Especially, systems relying on adap-tive generalized sidelobe canceller (GSC) structures are very promising , since they combine high noise-reduction performance with computational ef£ciency. So far,(More)
The homocysteine methyltransferase encoded by mmuM is widely distributed among microbial organisms. It is the key enzyme that catalyzes the last step in methionine biosynthesis and plays an important role in the metabolism process. It also enables the microbial organisms to tolerate high concentrations of selenium in the environment. In this research, 533(More)
Sodium fluoride (NaF) is a source of fluoride ions used in many applications. Previous studies found that NaF suppressed the proliferation of osteoblast MC3T3 E1 cells and induced the apoptosis of chondrocytes. However, little is known about the effects of NaF on human lung BEAS-2B cells. Therefore, we investigated the mode of cell death induced by NaF and(More)
Clinical history and physical examination are helpful in indicating the potential causes of pleural effusions (PEs). However, the accurate diagnosis and establishment of the causes of PE is an ongoing challenge in daily clinical practice. The primary aim of this study was to distinguish between infectious PE and malignant PE (MPE) by measuring two major(More)
Plasmids are important antibiotic resistance determinant carriers that can disseminate various drug resistance genes among species or genera. By using a high throughput sequencing approach, two groups of plasmids of Escherichia coli (named E1 and E2, each consisting of 160 clinical E. coli strains isolated from different periods of time) were sequenced and(More)
In order to get insights into plasmid evolution and the dissemination of multidrug resistance, we performed extensive comparative genomics analyses of the Klebsiella pneumoniae plasmid pKF3-94 and some of its related plasmids. pKF3-94 is one of three plasmids isolated from the K. pneumoniae strain KF3. Of the 144 putative genes it harbors, 69 can be(More)
