Concentration gradient driven molecular dynamics: a new method for simulations of membrane permeation and separation.

Chemical science

Ozcan A, Perego C, Salvalaglio M, Parrinello M, Yazaydin O.
PMID: 28966778
Chem Sci. 2017 May 01;8(5):3858-3865. doi: 10.1039/c6sc04978h. Epub 2017 Mar 20.

In this study, we introduce a new non-equilibrium molecular dynamics simulation method to perform simulations of concentration driven membrane permeation processes. The methodology is based on the application of a non-conservative bias force controlling the concentration of species at...

Human adipose-derived stem cells are an abundant population of stem cells readily isolated from human adipose tissue that can differentiate into connective tissue lineages including bone, cartilage, fat, and muscle. Activating transcription factor 5 is a transcription factor of...

Coarse graining from variationally enhanced sampling applied to the Ginzburg-Landau model.

Proceedings of the National Academy of Sciences of the United States of America

Invernizzi M, Valsson O, Parrinello M.
PMID: 28292890
Proc Natl Acad Sci U S A. 2017 Mar 28;114(13):3370-3374. doi: 10.1073/pnas.1618455114. Epub 2017 Mar 14.

A powerful way to deal with a complex system is to build a coarse-grained model capable of catching its main physical features, while being computationally affordable. Inevitably, such coarse-grained models introduce a set of phenomenological parameters, which are often...

Immunological deregulation in classic hodgkin lymphoma.

Mediterranean journal of hematology and infectious diseases

Romano A, Vetro C, Caocci G, Greco M, Parrinello NL, Di Raimondo F, La Nasa G.

Mediterr J Hematol Infect Dis. 2014 Jun 01;6(1):e2014039. doi: 10.4084/MJHID.2014.039. eCollection 2014.

Classic Hodgkin Lymphoma (cHL) has a unique histology since only a few neoplastic cells are surrounded by inflammatory accessory cells that in the last years have emerged as crucial players in sustaining the course of disease. In addition, recent...

Transient Polymorphism in NaCl.

Journal of chemical theory and computation

Giberti F, Tribello GA, Parrinello M.
PMID: 26583849
J Chem Theory Comput. 2013 Jun 11;9(6):2526-30. doi: 10.1021/ct4002027. Epub 2013 May 08.

We introduce a new collective variable (CV) that can be used to increase the frequency with which nucleation events are observed in biased atomistic simulations. This CV forces the ions to aggregate into clusters but does not force the...

Thermodynamical Description of a Quasi-First-Order Phase Transition from the Well-Tempered Ensemble.

Journal of chemical theory and computation

Valsson O, Parrinello M.
PMID: 26592265
J Chem Theory Comput. 2013 Dec 10;9(12):5267-76. doi: 10.1021/ct400859f. Epub 2013 Nov 21.

We explore the performance of the well-tempered ensemble combined with parallel tempering (PT-WTE) in obtaining a thermodynamical description of a given molecular system. We carefully explain the theoretical procedure employed to extract all the relevant thermodynamical quantities from a...

"We are what we eat!" Invasive intestinal mucormycosis: A case report and review of the literature.

Medical mycology case reports

Martinello M, Nelson A, Bignold L, Shaw D.
PMID: 24371738
Med Mycol Case Rep. 2012 Aug 04;1(1):52-5. doi: 10.1016/j.mmcr.2012.07.003. eCollection 2012.

Gastrointestinal mucormycosis is an uncommon, life-threatening, angioinvasive infection with only one previous report of disease involving the jejunum. We present a case of invasive jejunal mucormycosis and review the literature, highlighting the rare clinical presentation and the value of...

Counterion Redistribution upon Binding of a Tat-Protein Mimic to HIV-1 TAR RNA.

Journal of chemical theory and computation

Do TN, Ippoliti E, Carloni P, Varani G, Parrinello M.
PMID: 26596616
J Chem Theory Comput. 2012 Feb 14;8(2):688-94. doi: 10.1021/ct2005769. Epub 2012 Jan 20.

Binding of proteins and small molecules to RNA involves many electrostatic interactions, which may alter the distribution of ions around the RNA molecule. Here, we use molecular dynamics simulations to investigate how binding of a cyclic peptide mimic of...

Replica Temperatures for Uniform Exchange and Efficient Roundtrip Times in Explicit Solvent Parallel Tempering Simulations.

Journal of chemical theory and computation

Prakash MK, Barducci A, Parrinello M.
PMID: 26606473
J Chem Theory Comput. 2011 Jul 12;7(7):2025-7. doi: 10.1021/ct200208h. Epub 2011 Jun 22.

The efficiency of parallel tempering simulations is greatly influenced by the distribution of replica temperatures. In explicit solvent biomolecular simulations, where the total energy is dominated by the solvent, specific heat is usually assumed to be constant. From this,...

Trypanosoma brucei gambiense (Tbg), causing the sleeping sickness chronic form, completes its developmental cycle within the tsetse fly vector Glossina palpalis gambiensis (Gpg) before its transmission to humans. Within the framework of an anti-vector disease control strategy, a global...

Combustion chemistry via metadynamics: benzyl decomposition revisited.

The journal of physical chemistry. A

Atomistic simulations play a central role in many fields of science. However, their usefulness is often limited by the fact that many systems are characterized by several metastable states separated by high barriers, leading to kinetic bottlenecks. Transitions between...
