The evolutionary conditions for the dissipative continuous magnetohydrodynamic (MHD) shocks are studied. We modify Hada’s approach in the stability analysis of the MHD shock waves. The matching conditions between perturbed shock structure and asymptotic wave modes shows that all types of the MHD shocks, including the intermediate shocks, are evolutionary and perturbed solutions are uniquely def...

Small heat shock proteins (sHSPs), as ubiquitous molecular chaperones found in all forms of life, are known to be able to protect cells against stresses and suppress the aggregation of a variety of model substrate proteins under in vitro conditions. Nevertheless, it is poorly understood what natural substrate proteins are protected by sHSPs in living cells. Here, by using a genetically incorpor...

Heat shock proteins participate in the initiation of DNA replication of different organisms by facilitating the assembly of initiation complexes. We have examined the effects of human heat shock proteins (Hsp40 and Hsp70) on the interaction of the herpes simplex virus type-1 initiator protein (UL9) with oriS, one of the viral origins of replication. Hsp40 and Hsp70 act substoichiometrically to ...

Heat shock proteins (HSPs) are a class of functionally related proteins, the expression of which is increased when cells are exposed to elevated temperatures or other stresses, including infection, irradiation, heavy metals, ethanol, and oxidants. The aim of this study was to investigate the significance of HSP60, HSP70 and HSP27 as prognostic factors in different stages of oral carcinogenesis ...
