The cooperative behaviour of antimicrobial peptides in model membranes.

Biochimica et biophysica acta

Wang J, Mura M, Zhou Y, Pinna M, Zvelindovsky AV, Dennison SR, Phoenix DA.
PMID: 25046254
Biochim Biophys Acta. 2014 Nov;1838(11):2870-81. doi: 10.1016/j.bbamem.2014.07.002. Epub 2014 Jul 19.

A systematic analysis of the hypothesis of the antimicrobial peptides' (AMPs) cooperative action is performed by means of full atomistic molecular dynamics simulations accompanied by circular dichroism experiments. Several AMPs from the aurein family (2.5,2.6, 3.1), have a similar...

Rhenium-Catalyzed Construction of Polycyclic Hydrocarbon Frameworks by a Unique Cyclization of 1,n-Diynes Initiated by 1,1-Difunctionalization with Carbon Nucleophiles.

Angewandte Chemie (International ed. in English)

Murai M, Uemura E, Hori S, Takai K.
PMID: 28398619
Angew Chem Int Ed Engl. 2017 May 15;56(21):5862-5866. doi: 10.1002/anie.201701159. Epub 2017 Apr 11.

A regioselective cyclization of 1,n-diynes under rhenium catalysis was developed on the basis of a rare type of 1,1-difunctionalization of terminal alkynes with carbon nucleophiles, followed by sequential addition reactions of the resulting alkenylrhenium species. The reaction provides an...

Systematic reviews with language restrictions and no author contact have lower overall credibility: a methodology study.

Clinical epidemiology

Wang Z, Brito JP, Tsapas A, Griebeler ML, Alahdab F, Murad MH.
PMID: 25878512
Clin Epidemiol. 2015 Mar 31;7:243-7. doi: 10.2147/CLEP.S78879. eCollection 2015.

BACKGROUND: High-quality systematic reviews (SRs) require rigorous approaches to identify, appraise, select, and synthesize research evidence relevant to a specific question. In this study, we evaluated the association between two steps in the conduct of an SR - restricting...

Acceleration Effects of Phosphine Ligands on the Rhodium-Catalyzed Dehydrogenative Silylation and Germylation of Unactivated C(sp(3))-H Bonds.

The Journal of organic chemistry

Murai M, Takeshima H, Morita H, Kuninobu Y, Takai K.
PMID: 25961415
J Org Chem. 2015 Jun 05;80(11):5407-14. doi: 10.1021/acs.joc.5b00920. Epub 2015 May 18.

The current work describes the marked rate of acceleration caused by phosphine ligands on the rhodium-catalyzed dehydrogenative silylation and germylation of unactivated C(sp(3))-H bonds. The reactivity was affected by the steric and electronic nature of the phosphine ligands. The...

Isolation and structural characterization of geminal di(iodozincio)methane complexes stabilized with nitrogen ligands.

Journal of the American Chemical Society

Nishida Y, Hosokawa N, Murai M, Takai K.
PMID: 25539182
J Am Chem Soc. 2015 Jan 14;137(1):114-7. doi: 10.1021/ja5114535. Epub 2014 Dec 31.

Treatment of gem-di(iodozincio)methane with pyridine or diamine derivatives resulted in the isolation of a storable gem-di(iodozincio)methane species. Use of the sterically bulky bipyridine ligand gave a gem-di(iodozincio)methane complex, which allowed the first X-ray structural analysis of such species. This...

Remote information concentration using a bound entangled state.

Physical review letters

Murao M, Vedral V.
PMID: 11177829
Phys Rev Lett. 2001 Jan 08;86(2):352-5. doi: 10.1103/PhysRevLett.86.352.

Remote information concentration, the reverse process of quantum telecloning, is presented. In this scheme, quantum information originally from a single qubit, but now distributed into three spatially separated qubits, is remotely concentrated back to a single qubit via an...

Elasticity of a system with noncentral potentials.

Physical review. E, Statistical, nonlinear, and soft matter physics

Murat M, Kantor Y.
PMID: 17025611
Phys Rev E Stat Nonlin Soft Matter Phys. 2006 Sep;74(3):031124. doi: 10.1103/PhysRevE.74.031124. Epub 2006 Sep 27.

We derive expressions for determination of the stress and the elastic constants in systems composed of particles interacting via noncentral two-body potentials as thermal averages of products of first and second partial derivatives of the interparticle potentials and components...

Effect of aggregation on the excited-state electronic structure of perylene studied by transient absorption spectroscopy.

The journal of physical chemistry. A

Furube A, Murai M, Tamaki Y, Watanabe S, Katoh R.
PMID: 16706403
J Phys Chem A. 2006 May 25;110(20):6465-71. doi: 10.1021/jp060649b.

The effect of aggregation on the excited-state electronic structure of perylene was studied through transient absorption measurements of isolated molecules, excimers, monomeric crystals (beta-perylene), and dimeric crystals (alpha-perylene). Changes of electronic state were clearly identified from the changes in...

Separation of gas mixtures using a range of zeolite membranes: a molecular-dynamics study.

The Journal of chemical physics

PMID: 16008474
J Chem Phys. 2005 Jun 15;122(23):234708. doi: 10.1063/1.1930829.

Gas separation efficiencies of three zeolite membranes (Faujasite, MFI, and Chabazite) have been examined using the method of molecular dynamics. Our investigation has allowed us to study the effects of pore size and structure, state conditions, and compositions on...

Molecular dynamics simulations of gas separations using faujasite-type zeolite membranes.

PMID: 15267348
J Chem Phys. 2004 Mar 08;120(10):4877-85. doi: 10.1063/1.1645771.

Gas separations with faujasite zeolite membranes have been examined using the method of molecular dynamics. Two binary mixtures are investigated, oxygen/nitrogen and nitrogen/carbon dioxide. These mixtures have been found experimentally to exhibit contrasting behavior. In O(2)/N(2) mixtures the ideal...

BACKGROUND: The human placenta, a non-neuronal tissue, contains an active cholinergic system comprised of acetylcholine (ACh), choline acetyltransferase (ChAT), acetylcholinesterase (AChE), and high affinity muscarinic receptors. The cell(s) of origin of placental ACh and its role in trophoblast function...
