Profiling the effect of low frequency mechanical vibration on the metabolic and oxidative stress responses of A431 carcinoma

FEBS Open Bio, EarlyView.
20 Hz mechanical vibration induced A431 cancer cells' apoptosis without such effect on other healthy cell lines of L929 and C2C12. Lowered glucose consumption is observed specifically in A431. The expressions of ROS, HMGB1, and HSP1 levels initially increase and subsequently decrease in the cancer cell line, as opposed to L929 and C2C12, which ...

The Stagger Code for Accurate and Efficient, Radiation-coupled Magnetohydrodynamic Simulations

The Astrophysical Journal
We describe the Stagger code for simulations of magnetohydrodynamic (MHD) systems. This is a modular code with a variety of physics modules that will let the user run simulations of deep stellar atmospheres, sunspot formation, stellar chromospheres and ...

KOI-3158: The oldest known system of terrestrial-size planets

EPJ Web of Conferences, 2015
The first discoveries of exoplanets around Sun-like stars have fueled efforts to find ever smaller worlds evocative of Earth and other terrestrial planets in the Solar System. While gas-giant planets appear to form preferentially around metal-rich stars,

GDP‐fucose transporter SLC35C1: a potential regulatory role in cytosolic GDP‐fucose and fucosylated glycan synthesis

FEBS Open Bio, EarlyView.
The inactivation of SLC35C1 (GDP‐fucose transporter) and enzymes involved in GDP‐fucose biosynthesis was studied. Fucose supplementation increases the level of GDP‐fucose to abnormal, millimolar values in the absence of the TSTA3 protein and SLC35C1 in contrast to the GMDS/SLC35C1 double mutant.

Physical processes in stellar evolution [PDF]

, 2008
We firstly examine the possible roles of mass loss and mixing as a function of stellar masses. Then we review the present observational status about additional mixing processes in massive stars. Various evidences from main-sequence OB stars, from blue supergiants, from SN 1987A and from Wolf-Rayet stars are given in favour of a significant mixing in ...

Physical mechanisms of mixing in stellar interiors [PDF]

Symposium - International Astronomical Union, 1984
The different mechanisms by which mixing can take place in stellar interiors are considered : the classical Rayleigh-Benard instability with penetrative convection and over-shooting, semi-convection, gravitationnal and radiative settling, turbulent mixing.
