Molecular Processes in Chondrocyte Biology. [PDF]

open access: yesInt J Mol Sci, 2020
Chondrocyte biology is a hot topic, because osteoarthritis (OA) is a serious problem in an aging society, but there are no fundamental therapeutic drugs [...]

On determination of the cosmic ray flux using molecular hydrogen absorption lines [PDF]

open access: yesSerbian Astronomical Journal, 2003
We outline a procedure for estimating the cosmic ray flux at remote locations where molecular hydrogen absorption lines have been detected. The method relies on several assumptions whose validity in the local Galactic ISM has been independently verified,

Thermal Processes in Molecular Gas [PDF]

open access: yesSymposium - International Astronomical Union, 1991
The dynamics of the cold atomic and molecular gas, on which we focus here, is strongly affected by non equilibrium heating and cooling processes. We give two different examples, in which the breaking of the thermal balance is due respectively to variations of the incident ultraviolet radiation flux, and non equilibrium abundances ...

Polarization Transfer Rates by Isotropic Collisions between Astrophysical SiO Molecule and Electrons

open access: yesUniverse, 2022
We are interested in quantum calculations of polarization transfer (PT) rates due to collisions of the SiO molecule with the electrons. We determine the inelastic PT rates associated to the transitions: X 1Σ+→3Π; X 1Σ+→3Σ+; X 1Σ+→3Δ; X 1Σ+→3Σ−.

The Elucidation of the Molecular Mechanism of the Extrusion Process [PDF]

open access: yesMaterials, 2021
Extrusion is a popular method for producing homogenous population of unilamellar liposomes. The technique relies on forcing a lipid suspension through cylindrical pores in a polycarbonate membrane. The quantification of the extrusion and/or recalibration processes make possible the acquisition of experimental data, which can be correlated with the ...

Molecular simulations of cellular processes [PDF]

open access: yesBiophysical Reviews, 2017
It is, nowadays, possible to simulate biological processes in conditions that mimic the different cellular compartments. Several groups have performed these calculations using molecular models that vary in performance and accuracy. In many cases, the atomistic degrees of freedom have been eliminated, sacrificing both structural complexity and chemical ...

Molecular Processes in Biological Thermosensation [PDF]

open access: yesJournal of Biophysics, 2008
Since thermal gradients are almost everywhere, thermosensation could represent one of the oldest sensory transduction processes that evolved in organisms. There are many examples of temperature changes affecting the physiology of living cells. Almost all classes of biological macromolecules in a cell (nucleic acids, lipids, proteins) can present a ...

Cosmic-Ray Induced Diffusion in Interstellar Ices

open access: yesOpen Astronomy, 2014
Cosmic rays are able to heat interstellar dust grains. This may enhance molecule mobility in icy mantles that have accumulated on the grains in dark cloud cores.

The Effect of an Inert Solid Reservoir on Molecular Abundances in Dense Interstellar Clouds

open access: yesOpen Astronomy, 2012
The question, what is the role of freeze-out of chemical species in determining the molecular abundances in the interstellar gas is a matter of debate.
