Polymerization efficiency of bulk‐fill dental resin composites with different curing modes
Authors: Dionysopoulos Dimitrios , Tolidis Kosmas , Gerasimou Paris 
Published: January 2016

ABSTRACTThe aim of this study was to investigate the effect of four different curing modes on the polymerization efficiency of eight bulk‐fill composites. Five specimens for each material were prepared for Vickers hardness measurements. The measurements were performed at 0 and 2 or 4 mm from the top of the surface of the specimens 24 h after photopolymerization. Statistical analysis was performed with one‐way analysis of variance and Tukey post hoc tests at a level of significance of a = 0.05 where a is the the level of significance. The light‐curing mode affected the microhardness in all depths, but this influence was material‐dependent (pmat < 0.001), where pmat is the probability to be affected by the material. The Vickers hardness numbers of the tested composites at 0 mm ranged from 9.32 ± 0.87 to 72.58 ± 6.52 and those of the tested composites at 4 mm ranged from 5.48 ± 0.32 to 54.34 ± 2.27. The clinician has to be aware of the technical characteristics of the materials and light‐curing units (LCUs) to use the most appropriate combination of LCU, composite material, and application technique. © 2016 Wiley Periodicals, Inc.

Computational study on the drug resistance mechanism of HCV NS3 protease to BMS‐605339
Authors: Wang Huiqun , Guo Chenchen , Chen Bo‐Zhen , Ji Mingjuan 
Published: January 2016

AbstractNS3 protease plays a vital role in the replication of the hepatitis C virus (HCV). BMS‐605339 is a novel linear tetra‐peptide α‐ketoamide inhibitor of NS3 protease and shows specificity for HCV NS3 protease genotype 1a and genotype 1b. Mutation at the key site 168 of the HCV NS3 protease can induce resistance to BMS‐605339, which greatly affects the antiviral therapy efficacy to hepatitis C. In the present study, we employed molecular dynamics simulations, free energy calculations, and free energy decomposition to explore the drug resistance mechanism of BMS‐605339 due to the three representative mutations D168C/Y/V. The free energy decomposition analysis indicates that the decrease in the binding affinity is mainly attributed to the decrease in both van der Waals and electrostatic interactions. After detailed analysis of our calculated results, we observed that the break of the salt bridge between residues 155 and 168 caused by the mutations D168C/Y/V is the original reason for the decrease in the binding ability between BMS‐605339 and the mutant NS3 proteases. The obtained results will reveal the drug resistance mechanism between BMS‐605339 and the mutant NS3 proteases, and provide valuable clue for designing novel and more potent drugs to HCV NS3 protease.

AbstractA truncated precursor form of prostate‐specific antigen (PSA), [–2]proPSA, is a well‐known biomarker for prostate cancer. To develop a biomarker assay, highly purified [–2]proPSA is required as a standard reference and for generation of a specific antibody. In this study, we generated an efficient mammalian expression system for producing a recombinant [–2]proPSA‐human kappa constant domain (Cκ) fusion protein. N‐terminal amino acid sequencing using Edman degradation demonstrated that over 95% of the recombinant protein produced is [–2]proPSA, thereby showing for the first time that recombinant [–2]proPSA can be produced as a major fraction. We also generated a recombinant chicken antibody specific to [–2]proPSA but not cross‐reactive to recombinant [–7]proPSA‐Cκ, [–5]proPSA‐Cκ, and PSA purified from human seminal fluid in enzyme‐linked immunosorbent assay (ELISA) and immunoblot analysis. Also, the recombinant chicken antibody reacted to recombinant [–2]proPSA protein bound to an anti‐PSA antibody coated on the micrometer plate in a sandwich ELISA. All of these results suggest that the N‐terminus of the [–2]proPSA‐Cκ fusion protein resides on the exterior of the protein, thus allowing exposure to the antibody.

Published: January 2016

AbstractOccupational magnetic field (MF) exposure has been suggested as a risk factor for breast cancer in both men and women. Due to the rarity of this disease in men, most epidemiologic studies investigating this relationship have been limited by small sample sizes. Herein, associations of several measures of occupational MF exposure with breast cancer in men were investigated using data from the population‐based case–control component of the Canadian National Enhanced Cancer Surveillance System. Lifetime job histories were provided by 115 cases and 570 controls. Average MF exposure of individual jobs was classified into three categories (<0.3, 0.3 to <0.6, or ≥0.6 μT) through expert blinded review of participant's lifetime occupational histories. The impact of highest average and cumulative MF exposure, as well as exposure duration and specific exposure‐time windows, on cancer risk was examined using logistic regression. The proportion of cases (25%) with a highest average exposure of ≥0.3 μT was higher than among controls (22%). We found an elevated risk of breast cancer in men who were exposed to ≥0.6 μT (odds ratio [OR] = 1.80, 95% CI = 0.82–3.95) when compared to those with exposures <0.3 μT. Those exposed to occupational MF fields for at least 30 years had a nearly threefold increase in risk of breast cancer (OR = 2.77, 95% CI = 0.98–7.82) when compared to those with background levels of exposure. Findings for the other time‐related MF variables were inconsistent. Our analysis, in one of the largest case–control studies of breast cancer in men conducted to date, provides limited support for the hypothesis that exposure to MF increases the risk breast cancer in men.

Published: January 2016

AbstractOsteonecrosis (ON), a significant complication following treatment of acute lymphoblastic leukemia (ALL), has a profound impact on quality of life of ALL survivors. We studied incidence and outcome of ON in patients treated on or according to Australian and New Zealand Children's Haematology/ Oncology Group (ANZCHOG) study 8 at The Children's Hospital at Westmead. The study involved retrospective chart review of the patients. ON was defined by development of symptoms and confirmed by magnetic resonance imaging. From 2002–2011, 251 patients (143M, 108F, 59 Standard Risk (SR), 159 Medium Risk (MR) 5 High Risk (HR), and 28 Very high risk (VHR)) were treated according to study 8. Eighteen (7M, 11F, 2 SR, 12 MR, 4 VHR) patients developed ON (7.2%). Median age at diagnosis was 13.05 years(4.3–16.7). Incidence of ON in patients > 10 years at diagnosis was 29%. Six out of 18 patients developed ON after allogeneic stem cell transplantation. Median time from diagnosis to the development of ON following chemotherapy for ALL was 1.15 years (range 0.25–2.12). Most patients were treated with intravenous Zoledronic acid. At last follow‐up, three patients had undergone arthroplasty, two patients were symptom free, and the remaining 13 patients reported persistent pain with activity. A majority of patients with ON of the hips had radiological progression. Overall, 7% of patients with ALL developed ON. Age >10 years was the most important risk factor. At last follow‐up, 70% of patients had persistent symptoms. Although Zoledronic acid improved pain, most patients with ON of the hips had radiological progression.

AbstractThe unfolded protein response (UPR) initiated by the transmembrane kinase/ribonuclease Ire1 has been implicated in a variety of diseases. Ire1, with its unique position in the UPR, is an ideal target for the development of therapies; however, the identification of specific kinase inhibitors is challenging. Recently, the development of covalent inhibitors has gained great momentum because of the irreversible deactivation of the target. We identified and determined the mechanism of action of the Ire1‐inhibitory compound UPRM8. MS analysis revealed that UPRM8 inhibition occurs by covalent adduct formation at a conserved cysteine at the regulatory DFG+2 position in the Ire1 kinase activation loop. Mutational analysis of the target cysteine residue identified both UPRM8‐resistant and catalytically inactive Ire1 mutants. We describe a novel covalent inhibition mechanism of UPRM8, which can serve as a lead for the rational design and optimization of inhibitors of human Ire1.
DBU and DBU‐Derived Ionic Liquid Synergistic Catalysts for the Conversion of Carbon Dioxide/Carbon Disulfide to 3‐Aryl‐2‐oxazolidinones/[1,3]Dithiolan‐2‐ylidenephenyl‐ amine

Published: January 2016

AbstractAn intermolecular synergistic catalytic combination of 1,8‐diazabicyclo[5.4.0]undec‐7‐ene (DBU) and a DBU‐derived bromide ionic liquid has been developed for the conversion of CO2, epoxides, and amines under metal‐ and solvent‐free conditions. Various 3‐aryl‐2‐oxazolidinones are produced in moderate to excellent yields within a short reaction time. NMR spectroscopy and DFT calculations demonstrate that DBU as a hydrogen bond acceptor and the ionic liquid as a hydrogen bond donor activate the substrates cooperatively by inducing hydrogen bonds to promote the reaction effectively. Based on these results, a possible reaction mechanism on the synergistic catalysis of DBU and the ionic liquid is proposed. In addition, the reaction of CS2, ethylene oxide, and aniline catalyzed by the combination of DBU and the DBU‐derived ionic liquid also proceeds smoothly, which opens a hitherto unreported route to [1,3]dithiolan‐2‐ylidenephenylamine in a straightforward way.
Study of the Phosphoryl‐Transfer Mechanism of Shikimate Kinase by NMR Spectroscopy

Published: January 2016

AbstractThe phosphoryl‐transfer mechanism of shikimate kinase from Mycobacterium tuberculosis and Helicobacter pylori, which is an attractive target for antibiotic drug discovery, has been studied by 1D 1H and 31P NMR spectroscopy. Metaphosphoric acid proved to be a good mimetic of the metaphosphate intermediate and facilitated the ready and rapid evaluation by NMR spectroscopic analysis of a dissociative mechanism. The required closed form of the active site for catalysis was achieved by the use of ADP (product) or two synthetic ADP analogues (AMPNP, AMPCP). Molecular dynamics simulation studies reported here also revealed that the essential arginine (Arg116/Arg117 in H. pylori and M. tuberculosis, respectively), which activates the γ‐phosphate group of ATP for catalysis and triggers the release of the product for turnover, would also be involved in the stabilisation of the metaphosphate intermediate during catalysis. We believe that the studies reported here will be helpful for future structure‐based design of inhibitors of this attractive target. The approach is also expected be useful for studies on the possible dissociative mechanism of other kinase enzymes.
Tridecacyclene: A Cyclic Tetramer of Acenaphthylene

Published: January 2016

AbstractIn this manuscript, we describe the single‐step preparation of a cyclic tetramer of acenaphthylene through a Lewis acid‐catalyzed aldol cyclization of 1‐acenaphthenone. The previously unexplored cyclic tetramer material differs from the better‐known cyclic trimer, decacyclene, due to the presence of a central eight‐membered ring. This ring not only forces the molecule to distort significantly from planarity, but is also responsible for its unique electronic properties, including a decrease in the reduction potential (by about 0.4 eV) and optical gap (by about 0.73 eV), compared to the more planar decacyclene. The synthesized compound crystallizes into a unique packing structure with significant π‐stacking observed between adjacent molecules. Furthermore, due to its saddle‐like shape, the cyclic tetramer is able to form shape‐complementary interactions between its concave surface and the convex outer surface of buckminsterfullerene to generate cocrystalline supramolecular assemblies.
