Mitochondria manganese superoxide dismutase (SOD2) is an important antioxidant enzyme, deficiency of which is associated with various human diseases. The known primary regulation of SOD2 is through transcriptional activation. Here, we report that SOD2 is acetylated at Lys 68 and that this acetylation decreases SOD2 activity. Mitochondrial deacetylase SIRT3(More)
The presence of regulatory T cells in patients who received therapeutic cytokine-induced killer (CIK) cells may inhibit host immunity, leading to failed immunotherapy. In this study, we investigated the impact of using interleukin-6 (IL-6) on the phenotype alteration, proliferation, and cytotoxic activity of CIK cells generated from the peripheral blood(More)
A class-B optical link is demonstrated as a means to provide high spur-free dynamic-range (110.4 dB · Hz) with a minimum average received power associated with the optical carrier. The link uses optical frequency modulation, linear fiberBragg-grating frequency discriminators, and balanced detection to provide high linearity and maximum signal power. Shot(More)
Tendons and ligaments exhibit limited regenerative capacity following injury, with damaged tissue being replaced by a fibrotic scar. The physiological role of scar tissue is complex and has been studied extensively. In this study, we demonstrate that rat tendons contain a unique subpopulation of cells exhibiting stem cell characteristics, including(More)
AIMS Anemia and vitamin D deficiency (VDD) are both very important health issues, recent accumulating evidence shows that VDD is prevalent in individuals with anemia. This meta-analysis aimed to detect a relationship between VDD and anemia. METHODS We identified eligible studies by searching the Pub Med, Embase and Cochrane Library before October 2014.(More)
A Raman Lidar (RL) system is developed to measure the water vapor mixing ratio (WVMR) and aerosol optical property in Wuhan with high temporal-spatial resolution during rainless nights. The principle of the self-developed lidar system and data processing method are discussed. WVMR profiles of a representative case retrieved by RL, Radiosonde (RS), and(More)
Compressive sensing (CS) is a data acquisition technique that measures sparse or compressible signals at a sampling rate lower than their Nyquist rate. Results show that sparse signals can be reconstructed using greedy algorithms, often requiring prior knowledge such as the signal sparsity or the noise level. As a substitute to prior knowledge, cross(More)
We use plasmon enhancement to achieve terahertz (THz) photoconductive switches that combine the benefits of low-temperature grown GaAs with mature 1.5 μm femtosecond lasers operating below the bandgap. These below bandgap plasmon-enhanced photoconductive receivers and sources significantly outperform commercial devices based on InGaAs, both in terms of(More)

An adhesion-related protein of Lactobacillus acidophilus strain CICC 6074 involved in binding to Caco-2 cells and inhibiting Enteropathogenic Escherichia coli (EPEC) was isolated and characterized. The S-layer protein was extracted with 5M LiCl and the active fraction purified by gel filtration (G-75). The S-layer protein was visualized by SDS-PAGE and(More)
