Our previous studies demonstrated that 3-hydroxyphthalic anhydride-modified chicken ovalbumin (HP-OVA) exhibited potent antiviral activity against a broad spectrum of HIV, simian immunodeficiency virus, and herpes simplex virus, making it a promising candidate as a component of combination microbicide. We intended to evaluate potential the synergistic anti-HIV-1 effect of HP-OVA in combination with antiretroviral drug (ARV)-based microbicide candidates. The antiviral activity of HP-OVA and the ARVs, including HIV-1 entry inhibitors (T20, C52L, NB64, NBD556, AMD3100, and Maraviroc) and reverse transcriptase inhibitors (Tenofovir, UC781, and TMC120), tested alone or in combination, against HIV-1 X4 and R5 viruses, including some drug-resistant strains, was determined in MT-2 and peripheral blood mononuclear cells using p24 assay. The immune responses induced by HP-OVA that was applied in the vaginas of rats were detected by enzyme-linked immunosorbent assay. When each of these ARV-based microbicide candidates was combined with HP-OVA, synergistic activity was observed against infection by both X4 and R5 strains, and the degree of synergy differed in each case. HP-OVA was highly effective against several ARV-resistant HIV-1 strains, suggesting that combining HP-OVA with these ARV-based microbicide candidates might work cooperatively against both drug-sensitive and -resistant HIV-1 strains. Human body fluids and human proteins had little or no effects on HP-OVA-mediated inhibitory activity against HIV-1 infection. HP-OVA formulated in the universal gel maintained its antiviral activity for at least 1 month and only induced weak immune responses after its multiple applications in the vaginas of rats. Synergistic and complementary effects against infection by a broad spectrum of HIV-1 strains were observed by combining HP-OVA with the ARV-based microbicide candidates. These findings provide a sound scientific platform for the development of a safe, effective, and affordable combination microbicide to prevent the sexual transmission of HIV and other sexually transmissible viruses.

Seventy-two patients with NASH were included in this multiple-dose parallel controlled clinical trial and received a 12-week course of aspartate-ornithine granule treatment at either high-dose (6 g bid po; n = 38) or low-dose (3 g bid po; n = 34). Clinical efficacy was assessed by monitoring data from urinalysis, serologic tests (alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), and triglyceride (TG)), and abdominal computed tomography (CT) scan. Safety was assessed by occurrence of adverse events (fatigue, anorexia, abdominal distension, nausea, and vomiting). Statistical analyses were conducted to determine the significance of differences between parameters before (baseline) and after treatment. After 12 weeks of treatment, the liver and spleen CT ratios in both the high-dose group (0.89 +/- 0.19) and the low-dose group (0.80 +/- 0.15) were significantly higher than at baseline (S = 329, P less than 0.0001 and S = 246, P less than 0.0001); the overall improvement was more robust in the high-dose group (52.63%) than in the low-dose group (38.23%) (Z = -2.1042, P less than 0.05). After 6 and 12 weeks of treatment, the serum ALT levels in both the high-dose group and the low-dose group were significantly lower than at baseline (6 weeks: S = 324.5, P less than 0.0001 and S = 223, P less than 0.0001; 12 weeks: S = 370.5, P less than 0.0001 and S = 297.5, P less than 0.0001); the overall improvement was more robust in the high-dose group (79.0%) than in the low-dose group (53.0%) (Z = -2.0533, P less than 0.05). Similar trends were seen for the serum levels of AST and GGT after 6 and 12 weeks of treatment (all P less than 0.01) and serum levels of TG after 12 weeks of treatment. The rate of adverse reactions was low and similar between the two groups (high-dose: 4.8% and low-dose: 4.4%; all gastrointestinal). Aspartate-ornithine granule therapy was an effective and safe treatment of nonalcoholic steatohepatitis, with the higher dose of 6 g bid po providing more robust clinical benefit without affecting the safety profile.

However, the significance of MLL2 protein expression for the prognosis of DLBCL is unclear. In this study, we detected MLL2 protein expression in primary gastrointestinal diffuse large B cell lymphoma (PGI-DLBCL) samples by using tissue microarray immunohistochemistry, and analyzed the correlation between MLL2 protein expression and tumor proliferation activity. In addition, we investigated clinical significance of MLL2 protein expression for PGI-DLBCL prognosis. We found that there was significant difference in MLL2 protein expression between PGI-DLBCL and reactive hyperplasia of lymph node. High expression of MLL2 protein indicated higher clinical stage. In older patients (>60 years) with PGI-DLBCL, MLL2 protein expression was positively correlated with Ki-67 expression and negatively correlated with patient survival. Our data suggest that MLL2 protein is overexp...

The results show that between 350 nm and 550 nm six fluorescence peaks were found in the fourth-derivative spectra, which are representatives of non-pigments, chlorophylls and carotenoides respectively. The method makes Bacillariophyta and Dinophyta more distinguishable when the fourth-derivative spectra are compared with the chlorophyll fluorescence excitation spectra. It can be used not only to discriminate the two groups of algaes, but also to reduce the effect of noise. The fluorescence peaks in the fourth-derivative spectra are proved to be stable.
Direct application of network coding at the physical layer - physical layer network coding (PNC) ... more Direct application of network coding at the physical layer - physical layer network coding (PNC) - is a promising technique for two-way relay wireless networks. In a two-way relay network, relay nodes are used to relay two-way information flows between pairs of end nodes. This paper proposes a precise definition for PNC. Specifically, in PNC, a relay node does not decode the source information from the two ends separately, but rather directly maps the combined signals received simultaneously to a signal to be relayed. Based on this definition, PNC can be further sub-classed into two categories - PNCF (PNC over finite field) and PNCI (PNC over infinite field) - according to whether the network-code field (or groups, rings) adopted is finite or infinite. For each of PNCF and PNCI, we consider two specific estimation techniques for dealing with noise in the mapping process. The performance of the four schemes is investigated by means of analysis and simulation, assuming symbol-level synchronization only.

Reports of recent outbreaks of a SARS-like disease caused by Middle East respiratory syndrome coronavirus (MERS-CoV) have raised serious concerns of a possible reemergence of SARS-CoV, either by laboratory escape or the presence of a natural reservoir. Therefore, the development of effective and safe SARS vaccines is still needed. Based on our previous studies, we believe that the receptor-binding domain (RBD) in the S1 subunit of the SARS-CoV spike (S) protein is the most important target for developing a SARS vaccine. In particular, RBD of S protein contains the critical neutralizing domain (CND), which is able to induce highly potent neutralizing antibody response and cross-protection against divergent SARS-CoV strains. Furthermore, a RBD-based subunit vaccine is expected to be safer than other vaccines that may induce Th2-type immunopathology. This review will discuss key advances in the development of RBD-based SARS vaccines and the possibility of using a similar strategy to develop vaccines against MERS-CoV.

Jiang and colleagues previously reported that anhydride-modified proteins have inhibitory activities against multiple viruses including HPV. Here, we evaluated the safety of 3-hydroxyphthalic anhydride-modified bovine beta-lactoglobulin, designated JB01, vaginally applied in women infected by high-risk HPV. After the vaginal application of JB01 in 38 women for three month, no serious adverse events were reported, and normalization of the vaginal micro-environment has been observed. It can be concluded that JB01-BD is safe for vaginal use in HPV-infected women, suggesting its potential application for the treatment of HPV infection. This article is protected by copyright.

In this study, we reported a new bioelectrochemical method to produce GO from graphite under ambient conditions without chemical amendments, value-added organic compounds and high rate H2 were also produced. Compared with abiotic electrochemical electrolysis control, the microbial assisted graphite oxidation produced high rate of graphite oxide and graphene oxide (BEGO) sheets, CO2, and current at lower applied voltage. The resultant electrons are transferred to a biocathode, where H2 and organic compounds are produced by microbial reduction of protons and CO2, respectively, a process known as microbial electrosynthesis (MES). Pseudomonas is the dominant population on the anode, while abundant anaerobic solvent-producing bacteria Clostridium carboxidivorans is likely responsible for electrosynthesis on the cathode. Oxygen production through water electrolysis was not detected on the anode due to the presence of facultative and aerobic bacteria as O2 sinkers. This new method provides a sustainable route for producing graphene materials and renewable H2 at low cost, and it may stimulate a new area of research in MES.

C57BL/6 mice received TSLPR-Ig or controlled-Ig before being induced ALI. Lung wet/dry (W/D) weight ratio was recorded. Neutrophil number and albumin concentration of bronchoalveolar lavages fluids (BALF) were determined. Besides, bone marrow dendritic cells (BMDCs) were separated and cultured with medium, TSLP, TSLP plus TSLPR-Ig or TSLP plus controlled-Ig. Protein expression levels of TSLP in lung tissues, phosphorylation extracellular regulated protein kinases (pERK) 1/2, p38, and signal transducers and activators of transcription (STAT) 3 in BMDCs were analyzed using Western blotting. Expression of CD40, CD80 and CD86 on pulmonary DCs and BMDCs was determined using flow cytometry (FCM). The W/D ratio, neutrophil number and albumin concentration were significantly decreased in the TSLPR...

The removal performance and mechanisms of three ions, cadmium (Cd(2+)), lead (Pb(2+)) and chromium (Cr(3+)) were investigated individually and as a mixture under different applied voltages and ion concentrations. It was found that CDI could effectively remove these metals, and the performance was positively correlated with the applied voltage. When 1.2V was applied into solution containing 0.5mM individual ions, the Cd(2+), Pb(2+), and Cr(3+) removal was 32%, 43%, and 52%, respectively, and the electrosorption played a bigger role in Cd(2+) removal than for the other two ions. Interestingly, while the removal of Pb(2+) and Cr(3+) remained at a similar level of 46% in the mixture of three ions, the Cd(2+) removal significantly decreased to 14%. Similar patterns were observed when 0.05mM was used to simulate natural contaminated water conditi...
