—Mobile radio systems for public safety and agencies engaged in emergency response and disaster recovery operations must support multicast voice traffic. In this paper, we analyze the distribution of call interarrival and call holding times for multicast voice (talk group) traffic on a transmission trunked mobile radio system. In such systems, the channel(More)
BACKGROUND Xuesaitong (XST) injection, consisting of total saponins from Panax notoginseng, was widely used for the treatment of cardio- and cerebro-vascular diseases in China. This study develops a simple and global quality evaluation method for the quality control of XST. METHODS High performance liquid chromatography-ultraviolet detection (HPLC-UV) was(More)
The sensing of pathogen infection and subsequent triggering of innate immunity are key to controlling zoonotic infections. Myxoma virus (MV) is a cytoplasmic DNA poxvirus that in nature infects only rabbits. Our previous studies have shown that MV infection of primary mouse cells is restricted by virus-induced type I interferon (IFN). However, little is(More)
Esophageal squamous cell carcinoma (ESCC) is the main form of esophageal malignancy. The approach for early diagnosis of this malignancy is very limited. In the present study, we first evaluated glutathione S-transferase omega 1 (GSTO1), a protein related to metabolism, as a tumor-associated antigen in ESCC, and we also evaluated its autoantibody as a(More)
BACKGROUND Recently it was shown that retinal vessel diameters could be measured using spectral domain optical coherence tomography (OCT). It has also been suggested that retinal vessels manifest different features on spectral domain OCT (SD-OCT) depending on whether they are arteries or veins. Our study was aimed to present a reliable SD-OCT assisted(More)
BACKGROUND APE1 (apurinic/apyrimidinic endonuclease 1) is an important DNA repair protein in the base excision repair pathway. Polymorphisms in APE1 have been implicated in susceptibility to cancer; however, results from the published studies remained inconclusive. The objective of this study was to conduct a meta-analysis investigating the association(More)
Recent studies have reported that DNA methyl-transferases (DNMTs) and histone deacetylases (HDACs) are involved in the epigenetic regulation of cancer, as well as promoting cell proliferation and tumorigenesis. These mechanisms also play important roles in ovarian cancer, but little is known concerning the correlation of DNMTs and HDACs in ovarian cancer.(More)
BACKGROUND N-Myc downstream-regulated gene 2 (NDRG2), as a tumor suppressor, has been demonstrated to inhibit tumor invasion and migration of hepatocellular carcinoma (HCC) by reducing the expression of CD24, which has been identified as a prognostic factor for HCC patients. However, the clinical significance of combined NDRG2 and CD24 expression in HCC(More)
