This paper reports the effect of elevated pressure on the invasive phenotype of patterned three-dimensional (3D) aggregates of MDA-MB-231 human breast cancer cells. We found that the directionality of the interstitial pressure profile altered the frequency of invasion by cells located at the surface of an aggregate. In particular, application of pressure at one end of an aggregate suppressed in...

We suggest that the dynamics of stable viscous invasion fronts in porous media depends on the volume capacitance of the media. At high volume capacitance, our network simulations provide numerical evidence of a scaling relation between the front width and its velocity. In the low volume capacitance regime, we derive a new effective scaling supported by network simulations and that is in agreeme...

The most prominent complications of having liver diseases such as cirrhosis include ascites. Derived from the Greek word “askos” which means “sack”, ascites is characterized as the collection of fluid in the peritoneal cavity. Aside from liver diseases, it can also be caused by a wide range of reasons necessitating different means of definitive management. Therefore, the identification of the n...

BACKGROUND There is an association between periodontal diseases and preterm delivery. AIM To assess the relationship between periodontal diseases, ascending bacterial infection and placental pathology with preterm delivery. PATIENTS AND METHODS A periodontal examination and collection of amniotic fluid and subgingival plaque samples were performed in women with preterm labor with intact mem...

Simultaneous capillary dominated displacement of the wetting and non-wetting phases are processes of interest in many disciplines including modeling of the penetration of polluting liquids in hydrology or the secondary migration in petroleum reservoir engineering. Percolation models and in particular invasion percolation is well suited to characterize the slow immiscible displaceme...

The aims of this study were to determine whether sonographically measured cervical length is of value in the identification of microbial invasion of the amniotic cavity in women with preterm premature rupture of membranes (PPROM) and to compare its performance with maternal blood C-reactive protein (CRP), white blood cell count (WBC), and amniotic fluid (AF) WBC. This prospective observational ...

When magnetic fluid is confined with an immiscible fluid between closely spaced parallel plates, and a uniform magnetic field is applied normal to the plates, the interface between the fluids exhibits a threshold instability in which a comblike pattern is established [1]. At supercritical intensities of the magnetic field a mutual invasion of the two phases occurs, in which fingers of magnetic ...
