We consider a chemotaxis-Navier-Stokes system in two dimensional bounded domains. It is asserted that the chemotaxis admits time periodic solution under some conditions.

Abstract CD8+ T cells and NK are the primary line of defense against tumor cells. However, microenvironment impairs their anti-tumor capabilities. One key functions impaired is ability to infiltrate tumor, essential allow direct contact with a target cell its killing. Kv1.3 KCa3.1 K +channels have multitude that been established in cells: regulates cytotoxicity chemotaxis. less known about Here...

ABSTRACT RNA-seq analysis of Cupriavidus necator NH9, a 3-chlorobenzoate degradative bacterium, cultured with 3-chlorobenzaote and benzoate, revealed strong induction genes encoding enzymes in degradation pathways the respective compound, including to convert benzoate chlorocatechol catechol, respectively, ortho-cleavage pathway for conversion central metabolites. The transporters, components s...

In order to maximize the overall profit of supply chain fresh food e-commerce platform, coordination and optimization model platform based on improved bacterial foraging algorithm is constructed. The basic constructed through chemotaxis, reproduction, elimination & dispersal, by using four parts: individual parameter initialization, chemotaxis behavior, reproduction behavior migration so as...

Monocyte chemoattractant protein-1 (MCP-1)-induced monocyte chemotaxis is a major event in inflammatory disease. Our prior studies have demonstrated that MCP-1-dependent chemotaxis requires release of arachidonic acid (AA) by activated cytosolic phospholipase A(2) (cPLA(2)). Here we investigated the involvement of AA metabolites in chemotaxis. Neither cyclooxygenase nor lipoxygenase pathways we...
