We propose that the rheological properties of background fluid play an important role in the interaction of microorganisms with the flow field. The viscoelastic-induced migration of microorganisms in a vortical flow leads to the emergence of a limit cycle. The shape and formation rate of patterns depend on motility, vorticity strength, and rheological properties of the background fluid. Given t...

A mathematical model and computer code for simulat ing electrokinetic fluid and sample manipulations in microfabricated fluidic devices (microchips) are described. The model accounts for mass transport mechanisms such as electrophoretic migration, bulk fluid motion due to electroosmosis, and diffusion. The interactive computer program implementing the model is capable of handling different chan...

The macrophage migration inhibition test was applied to the study of delayed hypersensitivity in mice vaccinated intravenously with oil-treated cell walls of Mycobacterium bovis BCG. Migration inhibition of peritoneal exudate cells from sensitized mice was demonstrated directly upon incubation of the cells with purified protein derivative, but indicator cells such as normal peritoneal cells had...

Accelerations in migration, mobility, and processes of globalization recent decades have intersected with parallel developments information communications technology (ICT). These advances had profound influences on historical cultural research. With reference to a diverse range international projects, this paper outlines major directions opportunities the growing field Digital Historical Migrat...

The gravel packing completion method for horizontal wells has the advantages of maintaining high oil production a long time, wellbore stability, and preventing sand production, so it become preferred wells. At present, this technology still faces problems bed height poor migration. In order to improve efficiency in wells, pulsed is proposed first time. Based on mechanism hydraulic pulse, Euleri...

To date, adult lymphangiogenesis is not well understood. In this study we describe the evolution of lymphatic capillaries in regenerating skin and correlate lymphatic migration and organization with the expression of matrix metalloproteinases (MMPs), immune cells, the growth factors VEGF-A and VEGF-C, and the heparan sulfate proteogylcan perlecan, a key component of basement membrane. We show t...

PURPOSE There are a limited number of noninvasive methods available for the monitoring of neoplastic disease in the central nervous system. The goal of our study was to find reliable markers that could be used for disease monitoring as well as to identify new targets for the therapeutic intervention for malignant astrocytoma (WHO grades 3 and 4). EXPERIMENTAL DESIGN We employed proteomic tech...

The objective of this study was to evaluate the role of activated protein C (aPC), known to be a physiological anticoagulant, in ovarian cancer cell activation as well as in loss of clotting of cancer ascitic fluid. The effect of aPC on an ovarian cancer cell line (OVCAR-3) was tested in regards to i) cell migration and adhesion with the use of adhesion and wound healing assays as well as a dro...

Wellbore cement, a procedural component of wellbore completion operations, primarily provides zonal isolation and mechanical support of the metal pipe (casing), and protects metal components from corrosive fluids. These are essential for uncompromised wellbore integrity. Cements can undergo multiple forms of failure, such as debonding at the cement/rock and cement/metal interfaces, fracturing, ...

Lysophosphatidic acid (LPA) is present in abundance in serum resulting from platelet activation and is also found in other biological fluids. LPA controls numerous cellular responses and plays a role in specific functions such as wound healing, especially in the skin. Nevertheless, its presence in the skin has never been investigated. Since re-epithelialization occurs after blister rupture, we ...
