Authors: Maiorana Anthony , Yue Liang , Manas‐Zloczower Ica , Gross Richard 
Published: March 2016

ABSTRACTThe monofunctional glycidyl ether of eugenol (GE) was used as a reactive diluent for the diglycidyl ether of diphenolate n‐pentyl ester (DGEDP‐Pe). Viscosities of GE and DGEDP‐Pe are 25 mPa s and 11 Pa s, respectively. Compositions GE/DGEDP‐Pe epoxy resins with 5, 10, 15, 20, and 30 wt % GE were analyzed for viscosity reductions and, subsequently, cured with isophorone diamine. The glassy modulus of cured GE/DGEDP‐Pe epoxy resins remained between 2000 and 3000 MPa. The glass transition temperature decreased linearly, from 92 °C for neat DGEDP‐Pe, with progressively higher loadings of GE to 53 °C at the highest GE loading of 30 wt %. The thermal stability decreased as GE loading increased with a maximum of 30 °C loss in the onset of degradation at 5 wt % mass loss. The role of GE as a reactive diluent is discussed and a range of loadings was determined to be suitable for a vacuum infusion epoxy resin system. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.

Authors: Chang Xuesong , Ding Tongmei , Tian Hengshui , Wang Tiantian 
Published: March 2016

ABSTRACTBisphenol‐A polycarbonate (BAPC) was synthesized by solid‐state polymerization (SSP) using a semicrystalline prepolymer crystallized by antisolvent method. The antisolvent crystallization was investigated as a function of antisolvent types using X‐ray diffraction (XRD), different scanning calorimetry (DSC), and scanning electron microscopes (SEM). The results showed antisolvent types had a significant effect on the crystallization of BAPC. Prepolymer induced by acetone as an antisolvent gained a higher crystallinity of 37.0%, more uniform particle size, and mature crystal structure compared with the samples crystallized by methanol and ethanol. Then crystallization of BAPC by acetone was carried out at crystallization temperature in the range of 40–80 °C for 1–5 h. A high crystallinity of 42.0% was acquired with the crystallization conducted at 70 °C for 2 h. Prepolymer with appropriate crystallinity of 37.8% resulted in high‐molecular‐weight polymer of 57,411 via SSP due to the effect of crystallinity and plasticization of residual solvent. © 2016 Wiley Periodicals, Inc.

Published: March 2016

AbstractSurface modification of electrode active materials has garnered considerable attention as a facile way to meet stringent requirements of advanced lithium‐ion batteries. Here, we demonstrated a new coating strategy based on dual layers comprising antimony‐doped tin oxide (ATO) nanoparticles and carbon. The ATO nanoparticles are synthesized via a hydrothermal method and act as electronically conductive/electrochemically active materials. The as‐synthesized ATO nanoparticles are introduced on natural graphite along with citric acid used as a carbon precursor. After carbonization, the carbon/ATO‐decorated natural graphite (c/ATO‐NG) is produced. In the (carbon/ATO) dual‐layer coating, the ATO nanoparticles coupled with the carbon layer exhibit unprecedented synergistic effects. The resultant c/ATO‐NG anode materials display significant improvements in capacity (530 mA h g−1), cycling retention (capacity retention of 98.1 % after 50 cycles at a rate of C/5), and low electrode swelling (volume expansion of 38 % after 100 cycles) which outperform that of typical graphite materials. Furthermore, a full‐cell consisting of a c/ATO‐NG anode and an LiNi0.5Mn1.5O4 cathode presents excellent cycle retention (capacity retention of >80 % after 100 cycles). We envision that the dual‐layer coating concept proposed herein opens a new route toward high‐performance anode materials for lithium‐ion batteries.

Abstract

Background
Liver resection is a potentially curative approach for hepatocellular carcinoma (HCC). Laparoscopic liver resections may reduce complication rates, especially in patients with cirrhosis. The aim of this study was to compare the results of laparoscopic liver resection with those of open liver resection for HCC.

Methods
Patients with cirrhosis who underwent minor liver resections for HCC from 2006 to 2013 were identified retrospectively from a prospective database according to the technique adopted (laparoscopic or open). Short- and long-term outcomes were compared between the two groups before and after 1 : 1 propensity score matching.

Results
A total of 269 patients were considered: 226 who underwent open liver resection and 43 who had a laparoscopic procedure. The two groups differed at baseline in terms of median age, sex, performance status, tumour location and type of resection. After propensity score matching, two comparable groups of 43 patients each were obtained. Intraoperative bleeding, margin clearance and operative mortality were similar in the two groups, whereas complication rates were lower (49 versus 19 per cent in open versus laparoscopic groups respectively; P = 0·004) and median hospital stay was shorter (8 versus 5 days; P &lt; 0·001) in the laparoscopic group. On multivariable logistic regression analysis, the only independent factor that reduced the risk of postoperative complications was the use of laparoscopy (odds ratio 0·12, 95 per cent c.i. 0·03 to 0·55; P = 0·006). Median overall survival was 57·8 months in the open group and 48·8 months in the laparoscopic group (P = 0·802). Median disease-free survival was 31·7 and 25·5 months respectively (P = 0·990).

Conclusion
In comparison with the open approach, laparoscopic minor liver resections for HCC improved short-term outcomes, with similar survival results.

AbstractMoxifloxacin and rifampicin are all the first‐line options for the treatment of active tuberculosis, which are often combined for the treatment of multidrug resistance pulmonary tuberculosis in clinic. However, the potential drug–drug interactions between moxifloxacin and rifampicin were unknown. The aim of this study was to investigate the drug–drug interactions between moxifloxacin and rifampicin based on their pharmacokinetics in vivo after oral administration of the single drug and both drugs, and reveal their mutual effects on their pharmacokinetics. Eighteen male Sprague–Dawley rats were randomly assigned to three groups: moxifloxacin group, rifampicin group and moxifloxacin + rifampicin group. Plasma concentrations of moxifloxacin and rifampicin were determined using LC‐MS at the designated time points after drug administration, and the main pharmacokinetic parameters were calculated. In addition, effects of moxifloxacin and rifampicin on their metabolic rate and absorption were investigated using rat liver microsome incubation systems and Caco‐2 cell transwell model. The main pharmacokinetic parameters of moxifloxacin including Tmax, Cmax, t1/2 and AUC(0–t) increased more in the moxifloxacin + rifampicin group than in the moxifloxacin group, but the difference was not significant (p > 0.05). However, the pharmacokinetic parameters of rifampicin, including peak concentration, area under the concentration–time curve, half‐life and the area under the first moment plasma concentration–time curve, increased significantly (p < 0.05) compared with the rifampicin group, and the time to peak concentration decreased significantly (p < 0.05). The mean residence time of rifampicin also increased in moxifloxacin + rifampicin group compared with the rifampicin group, but the difference was not significant (p > 0.05). The rat liver microsome incubation experiment indicated that moxifloxacin could increase the metabolic rate of rifampicin from 23.7 to 38.7 min. However, the Caco‐2 cell transwell experiment showed that moxifloxacin could not affect the absorption rate of rifampicin. These changes could enhance the drug efficacy, but they could also cause drug accumulation, which might induce adverse effect, so it was suggested that the drug dosage should be adjusted and the drug concentration in plasma should be monitored if moxifloxacin and rifampicin are co‐administered.

Truncated Escherichia coli thioredoxin induces proliferation of human blood mononuclear cells and production of reactive oxygen species as well as proinflammatory cytokines
Authors: Liu Si‐Yen , Liu I‐Chung , Lin Tiao‐Yin 
Published: March 2016

Thioredoxin (Trx) is a redox protein characterized by a Trx fold. A naturally occurring truncated human Trx, Trx 80, which lacks the C‐terminal strand‐helix of the Trx fold, stimulates proliferation of peripheral blood mononuclear cells (PBMCs). It has not been clear how Trx80 gains this function. This study investigates whether a peptide with substantial sequence difference from Trx80, but retaining an abridged Trx fold can elicit PBMC proliferation. We genetically truncated a carboxy‐terminal β‐α motif of Escherichia coli Trx to produce a peptide, Trx83, which shares low sequence identity with human Trx80. Addition of reduced‐form Trx83 to resting human PBMCs promoted cell proliferation, while oxidized‐form Trx83 lacked the function. By contrast, oxidized‐form Trx80 exhibited a high activity in promoting PBMC proliferation, indicating the importance of sequence context of an abridged thioredoxin in influencing PBMC proliferation. Trx83 increases cellular reactive oxygen species and proinflammatory cytokines TNF‐α and IL‐1β, suggesting that Trx83 modulates inflammatory pathways. This notion is supported by the observation that cystine or cysteine abolishes the Trx83 induced PBMC proliferation. The PBMC stimulatory activity of Trx83 may have potential for pharmacological developments.Significance of the StudyElicitation of primary proliferative responses of PBMCs by a protein is generally difficult. We show that Escherichia coli Trx83 with a truncated Trx fold induces PBMC proliferation, but only in the disulfide‐reduced form. In contrast, oxidized‐form human Trx80 is a potent stimulator. These results demonstrate that the sequence context of an abridged Trx fold is influential in inducing PBMC proliferation. The stimulatory effect of Trx83 is associated with an increase of inflammatory response. The possibility of eliciting PBMC proliferation and switching this activity on/off by redox control provides a perspective for developing Trx83 as a PBMC stimulatory agent.
