Direct Imaging of Photo-Switching Molecular Conformations Using Individual Metal Atom Markers.

ACS Nano 2018 Dec 6. Epub 2018 Dec 6.

Photo-switching behavior of individual organic molecules was imaged by annular dark-field scanning transmission electron microscopy (ADF-STEM) using a highly electron beam transparent graphene support. Photo-switching azobenzene derivatives with ligands at each ends containing single transition metal atoms (Pt) were designed (Pt-complex), and the distance between the strong ADF-STEM contrast from the two Pt atoms in each Pt-complex is used to track molecular length changes. UV irradiation was used to induce photo-switching of the Pt complex on graphene, and we show that the measured Pt-Pt distances within isolated molecules decreases from ~2. Read More

Rational design and observation of the tight interface between graphene and ligand protected nanocrystals.

Phys Chem Chem Phys 2018 Dec 6. Epub 2018 Dec 6.

Center for Nanoparticle Research, Institute for Basic Science (IBS), Seoul 08826, Republic of Korea and School of Chemical and Biological Engineering, Institute of Chemical Process, Seoul National University, Seoul 08826, Republic of Korea.

Heterostructures constructed of graphene and colloidal nanocrystals provide a unique way to exploit the coupled physical properties of the two functional building blocks. Studying the interface structure between the two constituent materials is important to understand the formation mechanism and the resulting physical and chemical properties. Along with ab initio calculations, we elucidate that the bending rigidity and the strong van der Waals interaction of graphene to the metal surface guide the formation of a tight and conformal interface.

Temperature-sensitive origin-binding protein as a tool for investigations of herpes simplex virus activities in vivo.

J Gen Virol 2018 Dec 6. Epub 2018 Dec 6.

Institute of Virology, University of Bonn, Bonn, Germany.

While it is fairly clear that herpes simplex virus (HSV) DNA replication requires at least seven virus-encoded proteins in concert with various host cell factors, the mode of this process in infected cells is still poorly understood. Using HSV-1 mutants bearing temperature-sensitive (ts) lesions in the UL9 gene, we previously found that the origin-binding protein (OBP), a product of the UL9 gene, is only needed in the first 6 hours post-infection. As this finding was just a simple support for the hypothesis of a biphasic replication mode, we became convinced through these earlier studies that the mutants tsR and tsS might represent suitable tools for more accurate investigations in vivo.

Special features of monolayer characteristics of N-alkanoyl substituted threonine amphiphiles.

Phys Chem Chem Phys 2018 Dec 6. Epub 2018 Dec 6.

Max Planck Institute of Colloids and Interfaces, D-14424 Potsdam/Golm, Germany.

The monolayers of N-alkanoyl substituted threonine amphiphiles, similar to those of other N-alkanoyl-substituted amino acid amphiphiles, point to substantial differences in the main characteristics compared to usual amphiphilic monolayers. π-A measurements of the enantiomeric and racemic forms of N-alkanoyl-substituted threonine monolayers with C16 and C18 chain lengths reveal that, independent of the alkyl chain length, all compression curves are located above the corresponding decompression curves. A theoretical model developed for the kinetics of two-dimensional condensation of Langmuir monolayers can describe this behavior concluding the attachment of monomers to large aggregates. Read More

Consistent success in life-supporting porcine cardiac xenotransplantation.

Nature 2018 Dec 5. Epub 2018 Dec 5.

Department of Anaesthesiology, University Hospital, LMU Munich, Munich, Germany.

Heart transplantation is the only cure for patients with terminal cardiac failure, but the supply of allogeneic donor organs falls far short of the clinical need. Xenotransplantation of genetically modified pig hearts has been discussed as a potential alternative. Genetically multi-modified pig hearts that lack galactose-α1,3-galactose epitopes (α1,3-galactosyltransferase knockout) and express a human membrane cofactor protein (CD46) and human thrombomodulin have survived for up to 945 days after heterotopic abdominal transplantation in baboons.

Direct van der Waals Epitaxy of Crack-Free AlN Thin Film on Epitaxial WS₂.

Materials (Basel) 2018 Dec 4;11(12). Epub 2018 Dec 4.

Research and Development Center for Solid State Lighting, Institute of Semiconductors, Chinese Academy of Sciences, Beijing 100083, China.

Van der Waals epitaxy (vdWE) has drawn continuous attention, as it is unlimited by lattice-mismatch between epitaxial layers and substrates. Previous reports on the vdWE of III-nitride thin film were mainly based on two-dimensional (2D) materials by plasma pretreatment or pre-doping of other hexagonal materials. However, it is still a huge challenge for single-crystalline thin film on 2D materials without any other extra treatment or interlayer. Read More

Ultralow Interlayer Friction of Layered Electride Ca₂N: A Potential Two-Dimensional Solid Lubricant Material.

Materials (Basel) 2018 Dec 4;11(12). Epub 2018 Dec 4.

Computational and Design Center for Low-dimensional Quantum Material, and College of Science, Zhongyuan University of Technology, Zhengzhou 450007, China.

Dispersion-corrected density functional theory (DFT) calculations reveal that the layered electride of dicalcium nitride (Ca₂N) exhibits stronger interlayer binding interactions but lower interlayer friction behavior than that of traditional layered lubricants weakly bonded by van der Waals (vdW) interactions, such as graphite, -BN, and MoS₂. These results are attributed to the two-dimensional (2D) homogeneous conduction electrons distribution in the middle of the interlayer space of Ca₂N, which yields a smooth sliding barrier and hence ultralow friction behavior. The interesting results obtained in this study have not only broadened the scope of 2D solid lubricants but also enriched the physical understanding of ultralow friction mechanism for 2D systems.

Rapid developments in imaging and treatment with radiopharmaceuticals targeting prostate cancer pose issues for the development of guidelines for their appropriate use. To tackle this problem, international experts representing medical oncologists, urologists, radiation oncologists, radiologists, and nuclear medicine specialists convened at the European Association of Nuclear Medicine Focus 1 meeting to deliver a balanced perspective on available data and clinical experience of imaging in prostate cancer, which had been supported by a systematic review of the literature and a modified Delphi process. Relevant conclusions included the following: diphosphonate bone scanning and contrast-enhanced CT are mentioned but rarely recommended for most patients in clinical guidelines; MRI (whole-body or multiparametric) and prostate cancer-targeted PET are frequently suggested, but the specific contexts in which these methods affect practice are not established; sodium fluoride-18 for PET-CT bone scanning is not widely advocated, whereas gallium-68 or fluorine-18 prostate-specific membrane antigen gain acceptance; and, palliative treatment with bone targeting radiopharmaceuticals (rhenium-186, samarium-153, or strontium-89) have largely been replaced by radium-223 on the basis of the survival benefit that was reported in prospective trials, and by other systemic therapies with proven survival benefits.

Supramolecular chemistry is a major area of chemistry that utilizes weaker non-covalent interactions between molecules, including hydrogen bonding, van der Waals, electrostatic, π···π, and C-H···π interactions. Such forces have been the basis of several molecular self-assemblies and host-guest complexes in organic, inorganic, and biological systems. Atomically precise nanoclusters (NCs) are materials of growing interest that display interesting structure-property correlations. Read More

Association of baseline peptidylarginine deiminase 4 autoantibodies with favorable response to treatment escalation in rheumatoid arthritis.

Arthritis Rheumatol 2018 Dec 3. Epub 2018 Dec 3.

VA Nebraska-Western Iowa Health Care System, Omaha, NE, 68105.

Objective: To determine if the baseline presence of autoantibodies to peptidylarginine deiminase 4 (PAD4) predicts therapeutic response to biologic and conventional disease-modifying antirheumatic drugs (DMARDs) in patients with rheumatoid arthritis (RA) who failed methotrexate (MTX) monotherapy.

Methods: Baseline serum from 282 RA patients who failed MTX monotherapy were screened for the presence of anti-PAD4 antibodies by immunoprecipitation. Clinical response to either triple DMARD (MTX, sulfasalazine, and hydroxychloroquine) or MTX-etanercept combination therapy was determined at 24- and 48-weeks post-treatment initiation. Read More

Challenges in HSV encephalitis: normocellular CSF, unremarkable CCT, and atypical MRI findings.

Infection 2018 Dec 1. Epub 2018 Dec 1.

Department of Neurology, Klinikum der Ludwig-Maximilians-University (LMU) Munich, Marchioninistr. 15, 81377, Munich, Germany.

Purpose: Herpes simplex virus (HSV) encephalitis continues to be the most common form of sporadic lethal encephalitis worldwide. The wide spectrum of clinical presentations and laboratory findings often poses a diagnostic challenge for physicians which might delay administration of life-saving therapy with acyclovir. Atypical presentations of HSV encephalitis have become increasingly prevalent with better diagnostic techniques and have not been well studied. Read More

In the previous paper, we reviewed the origins of energy based calculations, and the early science of FF development. The initial efforts spanning the period from roughly the early 1970s to the mid to late 1990s saw the development of methodologies and philosophies of the derivation of FFs. The use of Cartesian coordinates, derivation of the H-bond potential, different functional forms including diagonal quadratic expressions, coupled valence FFs, functional form of combination rules, and out of plane angles, were all investigated in this period.

Biomolecular force fields: where have we been, where are we now, where do we need to go and how do we get there?

J Comput Aided Mol Des 2018 Nov 30. Epub 2018 Nov 30.

Department of Chemistry, University of Massachusetts, Amherst, MA, 01003, USA.

In this perspective, we review the theory and methodology of the derivation of force fields (FFs), and their validity, for molecular simulations, from their inception in the second half of the twentieth century to the improved representations at the end of the century. We examine the representations of the physics embodied in various force fields, their accuracy and deficiencies. The early days in the 1950s and 60s saw FFs first introduced to analyze vibrational spectra. Read More
