Biophysical reviews

Levens D, Baranello L, Kouzine F.
PMID: 28510225
Biophys Rev. 2016 Sep;8(3):259-268. doi: 10.1007/s12551-016-0216-8. Epub 2016 Aug 20.

Transcription initiation is a major control point for the precise regulation of gene expression. Our knowledge of this process has been mainly derived from protein-centric studies wherein cis-regulatory DNA sequences play a passive role, mainly in arranging the protein...

Subsystem density-functional theory (DFT) is an emerging technique for calculating the electronic structure of complex molecular and condensed phase systems. In this topical review, we focus on some recent advances in this field related to the computation of condensed...

High-Density Lipoprotein, Lecithin: Cholesterol Acyltransferase, and Atherosclerosis.

Endocrinology and metabolism (Seoul, Korea)

Ossoli A, Pavanello C, Calabresi L.
PMID: 27302716
Endocrinol Metab (Seoul). 2016 Jun;31(2):223-9. doi: 10.3803/EnM.2016.31.2.223. Epub 2016 Jun 10.

Epidemiological data clearly show the existence of a strong inverse correlation between plasma high-density lipoprotein cholesterol (HDL-C) concentrations and the incidence of coronary heart disease. This relation is explained by a number of atheroprotective properties of HDL, first of...

Front Immunol. 2017 May 09;8:516. doi: 10.3389/fimmu.2017.00516. eCollection 2017.

Aging is an emerging worldwide threat to public health, even in the workplace, as it links with risk of illness and death. Bewildered inflammatory responses and stressful conditions associate with age-related disorders. Additionally, circadian rhythm disruption, a critical health...

Exploiting the locality of periodic subsystem density-functional theory: efficient sampling of the Brillouin zone.

Journal of physics. Condensed matter : an Institute of Physics journal

Genova A, Pavanello M.
PMID: 26596499
J Phys Condens Matter. 2015 Dec 16;27(49):495501. doi: 10.1088/0953-8984/27/49/495501. Epub 2015 Nov 24.

In order to approximately satisfy the Bloch theorem, simulations of complex materials involving periodic systems are made n(k) times more complex by the need to sample the first Brillouin zone at n(k) points. By combining ideas from Kohn-Sham density-functional...

The visible spectrum of H3(+) is studied using high-sensitivity action spectroscopy in a cryogenic radiofrequency multipole trap. Advances are made to measure the weak ro-vibrational transitions from the lowest rotational states of H3(+) up to high excitation energies providing...

Exact kinetic energy enables accurate evaluation of weak interactions by the FDE-vdW method.

The Journal of chemical physics

Sinha D, Pavanello M.
PMID: 26328831
J Chem Phys. 2015 Aug 28;143(8):084120. doi: 10.1063/1.4928531.

The correlation energy of interaction is an elusive and sought-after interaction between molecular systems. By partitioning the response function of the system into subsystem contributions, the Frozen Density Embedding (FDE)-vdW method provides a computationally amenable nonlocal correlation functional based...
