objective(s):hyperglycemia worsens the neuronal death induced by cerebral ischemia. previous studies demonstrated that diabetic hyperglycemia suppressed the expression of heat shock protein 70 and 60 (hsp70 and 60) in the liver. igg antibody titres against heat shock protein 27 (anti hsp27) were measured to determine whether hyperglycemia exacerbates ischemic brain damage by suppressing the exp...

Hundreds of impact craters on Mars contain diverse phyllosilicates, interpreted as excavation products of preexisting subsurface deposits following impact and crater formation. This has been used to argue that the conditions conducive to phyllosilicate synthesis, which require the presence of abundant and long-lasting liquid water, were only met early in the history of the planet, during the No...

Thin-shell instability is one process which can generate entangled structures in astrophysical plasma on collisional (fluid) scales. It is driven by a spatially varying imbalance between the ram pressure of the inflowing upstream plasma and the downstream's thermal pressure at a nonplanar shock. Here we show by means of a particle-in-cell simulation that an analog process can destabilize a thin...

Here we present an in vivo footprinting analysis of the Saccharomyces cerevisiae HSP82 promoter. Consistent with current models, we find that yeast heat shock factor (HSF) binds to strong heat shock elements (HSEs) in non-heat-shocked cells. Upon heat shock, however, additional binding of HSF becomes apparent at weak HSEs of the promoter as well. Recovery from heat shock results in a dramatic r...

The scattering time is an important factor which is connected with the maximum energy particle in the diffusive shock. In present simulations, the maximum momentum is calculated by allowing us to determine the scattering probability by scattering time in the scattering processes. We obtain the shape of the energy spectrum with cutoff at some maximum momentum. Also, we find that the value of the...

We illustrate in a simple setting the instantaneous shock tracking approach to stability of viscous conservation laws introduced by Howard, Mascia, and Zumbrun. This involves a choice of the definition of instanteous location of a viscous shock– we show that this choice is time-asymptotically equivalent both to the natural choice of leastsquares fit pointed out by Goodman and to a simple phase ...

We consider dispersive optical shock waves in nonlocal nonlinear media. Experiments are performed using spatial beams in a thermal liquid cell, and results agree with a hydrodynamic theory of propagation.
