Finally, ten units ( 212.9 ml / unit ± 9.5 ml / unit ) of thawed human red blood cells (cryopreserved with 40% (w/v) glycerol) were deglycerolized using the theoretically optimal operation protocols to further validate the effectiveness and advantage...

... to the interface can result in a considerable increase in aneurysm wall stress in cases of partial attachment. In the search for models capable of accurately assessing the risk for rupture, the nature of the thrombus and its attachment to the aneurysm wall must be carefully assessed. blood computerised...

... for the concentration of an absorbed vapor in an air-mucus-tissue-blood (AMTB) model of the respiratory wall was developed for transient and variable air-phase concentrations. Based on the analytical expression, a flux boundary condition was developed at the air-mucus interface as a function of the far-field air-phase...

...Youhua Tan; Dong Sun; Wenhao Huang Mechanical properties of red blood cells (RBCs) play an important role in regulating cellular functions. Many recent researches suggest that the cell properties or deformability may be used as a diagnostic indicator for the onset and progression of some human...

The shape of the layered structure formed by the sedimentation of particles is in close agreement with the shape of commonly observed grade-1 hyphema, where blood occupies less than one-third of the anterior chamber (Fig. 1c ). The shape of hyphema predicted inside...
