The aim of this work is the study of the two dimensional laminar compressible boundary layer ̄ow, with an adverse pressure gradient in the presence of heat and mass transfer. The partial di€erential equations and their boundary conditions, describing the problem under consideration, are transformed using the compressible Falkner±Skan transformation and the numerical solution of the problem is o...

Diatoms possess silica-based cell walls with species-specific structures and ornamentations. Silica deposition in diatoms offers a model to study the processes involved in biomineralization. A new wall is produced in a specialized vesicle (silica deposition vesicle, SDV) and secreted. Thus proteins involved in wall biogenesis may remain associated with the mature cell wall. Here it is demonstra...

Plant sterols have shown potent anti-proliferative effects and apoptosis induction against breast and prostate cancers. However, the effect of sterols against hepatic cancer has not been investigated. In the present study, we assessed whether the stigmasterol isolated from Navicula incerta possesses apoptosis inductive effect in hepatocarcimona (HepG2) cells. According to the results, Stigmaste...
