Cell division plays important roles in tissue growth. In pseudostratified epithelia, each cell nucleus migrates apically to facilitate planar-oriented division. density and adhesion between cells are known be two factors that control the migration of nucleus. We have constructed a biomechanical model investigate mechanism upward The cytoplasm is modeled as different 3D viscoelastic bodies follo...

  Introduction: Radiation Induced Bystander Effect (RIBE) which cause radiation effects in non-irradiated cells, has challenged the principle according to which radiation traversal through the nucleus of a cell is necessary for producing biological responses. What is the mechanism of this phenomenon? To have a better understanding of this rather ambiguous concept substantial number of original ...

methods campylobacter jejuni atcc 33291 and seven isolates donated from instituto de biotecnologia were used in this study. the presence of cdt genes in c. jejuni strains was determined by pcr. to evaluate the effect of cdt, hela cells were treated with bacterial lysate, and the damage and morphological changes were analyzed by microscopy, immunofluorescence staining, and flow cytometry. to eva...

objective(s):leptin is a novel and interesting hormone for anyone trying to lose weight, but its effects on male gonad structure in longitudinal study is unknown. the present study was designed to explore morphometrical changes of mouse testicular tissue after long-term administration of leptin. materials and methods:thirty healthy mature male mice were randomly assigned to either control (n=15...

The complexity of the cell structure and high overlap causes poor image contrast. Complex imaging factors in lighting differences, dye concentrations, other variables such as drying air, excess blood, mucus, bacteria, or inflammation can make automatic visual interpretation more difficult. This study proposes an approach model by combining basic processing techniques deep learning for segmentat...
