Adhesion

cancer begins to develop when cells grow abnormally in the lung tissue. Cancer Cells vs. Normal Cells Normal Cells and Cancer cells are two complete different thigs. The normal cells reproduce correctly, communicate correctly, and cell adhesion is taking place correctly also. One of the…

Introduction: Nano tribology is a study field of interfacial phenomenon in nano scale. The interaction between two contacting solids during a relative motion from atomic to microscale is important to understand the friction, wear, adhesion, indentation phenomenon. Now a days it has a plenty application in micro electro mechanical system (MEMS), nano electro mechanical system (NEMS), magnetic storage, lubricant manufacturing and many more field. There are few instruments in the market…

Nanosilver Impregnation A 400 ppm aqueous dispersion of silver nanoparticles was produced and applied to the specimens using electrochemical technique. The size range of silver nanoparticles was 30-80 nm. The pH of the suspension was 6-7; two kinds of surfactants (anionic and cationic) were used in the suspension as stabilizer; the concentration of the surfactants was three times the nano-silver particles. Empty-cell impregnation process (Rueping method) was carried out in pressure vessel under…

mediate cell-cell adhesion by interacting with adjacent cell in an anti-parallel conformation, forming a linear zip-like adhesion between cells.(9) The adhesion is calcium dependent.(10) N-cadherin have roles in development, neural tissues, cardiac muscles and in cancer metastasis. This does this via cadherin switching, which is a process where there are switches in E-cadherin expression and expression of N-cadherin, as they are complimentary to each other.(10) Loss of cell-cell adhesion is…

Although the function of ICAM5 in the pituitary is unknown, its roles in the brain as a cell adhesion molecule have been extensively studied. ICAM5 is abundantly expressed in the dendritic filopodia and plays an important role in synapse formation with presynaptic axons, via the extracellular matrix molecule, vitronectin (63), and/or β1 integrins (32, 64). Once these connections are established, the extracellular domain of ICAM5 is cleaved, disrupting the cytoplasmic actin cytoskeleton through…

The reduction in the spreading velocity of KO platelets suggests that loss of Calponin hinders actin polymerization, leading to a delay in response to the contact with collagen. These results indicate Calponin plays an important role in platelet adhesion and clot formation and supports our hypothesis. Lack of Calponin in platelets delays platelet activation and mobility. This supports our original hypothesis that Calponin is an important part of actin myosin filament in platelets and plays a…

Chapter 1 Atherosclerosis Structure of the normal artery: Cell types composing the normal artery: Endothelial Cells: The endothelial cell (EC) of the arterial intima constitutes an important contact surface with blood. It plays an important role in vascular homeostasis. This blood compatibility is due to presences of heparan sulfate proteoglycan molecules on the surface of the EC. These molecules can serve as a cofactor for antithrombin III, which inhibit thrombin. The surface of the EC also…

argument that anthocyanidin prevent type P fimbriae from attaching to uroepithelium and even prohibit or reduce expression of fimbriae right at the nuclear level. The theory is backed by the fact that anthocyanidins are very effective in preventing adhesion but not in dislodging bacteria that are bound actively. This theory explains why cranberry is effective if administered as a preventive measure rather than a curative…

To get a better idea about the importance of water and why it is one of the most important substances in the universe, I enjoyed this video on YouTube called Water – Liquid Awesome: Crash Course Biology #2. We can start by expressing that it is important to know that water is the only substance on our plant that occurs naturally in solid, liquid and gas forms. All life on earth is dependent on there being water. Water (H2O) is a covalent bond which is made up for two hydrogens and one oxygen.…

Helicobacter pylori are crucial during the initial phase of the stomach colonization as wells for survival since attachment provide the means by which H. pylori obtains nutrients [116]. H. pylori possess two major adhesion molecules of BabA and SabA. The blood group antigen binding adhesion (Bab A) allows Helicobacter pylori connect to the Lewis b blood group antigen and H antigen type 1…
