Lake Benthic Algal Production and Extracellular Material
… its importance to the lake as a whole. Benthic extracellular material, shown to be important for food web dynamics and stabilization of the surrounding ecosystem in the marine intertidal, is even less frequently studied in lakes. I examined the environmental and community level drivers of …

ΣΥΜΒΟΛΗ ΣΤΗ ΜΕΛΕΤΗ ΚΑΙ ΤΟ ΧΑΡΑΚΤΗΡΙΣΜΟ ΤΗΣ ΕΞΩΚΥΤΤΑΡΙΑΣ ΟΥΣΙΑΣ (SLIME) ΒΑΚΤΗΡΙΑΙΜΙΚΟΥ ΒΛΕΝΝΩΔΟΥΣ ΚΑΙ ΘΥΓΑΤΡΙΚΟΥ ΜΗ ΒΛΕΝΝΩΔΟΥΣ ΣΤΕΛΕΧΟΥΣ PSEUDOMONAS AERUGINOSA
… BY SERIAL PASSAGE ON TRYPTICASE SOY AGAR. THE EXTRACELLULAR MATERIAL (SLIME) FROM BOTH STRAINS WAS EXTRACTED BY METHODS AS FOR THE EXTRACTION OF GLYCOLIPOPROTEIN (GLP). GROSS CHEMICAL ANALYSES OF THE MS'S AND RNMV'S SLIME FOR URONIC ACIDS, CARBOHYDRATES, PROTEINS AND LIPIDS WERE 65%, 5.5%, …

A Nanoindentation Device and the Scale-Dependent Mechanical Properties of Native and Decellularized Liver Tissue
… an organ leaving behind an intact structure of extracellular material to act as a scaffold for new cells. Characterizing the biomechanical properties of these scaffolds is important due to the mechanosensitivity of many cell types. In addition, in the emerging field of multi-scale modeling an …

REGULATED UPTAKE OF BIOPOLYMERS Role of cell surface proteoglycans Implications for drug and gene delivery
… Internalization, i.e. cellular import of extracellular material, is a fundamental process, which provides cells with nutrients and enables the immune cells of higher organisms to remove debris, sample their surroundings for antigens and to fight microbes. Moreover, internalization …

Surface Displayed SNAP as a New Reporter in Synthetic Biology
… synthetic gene outputs by visualizing an extracellular synthetic green fluorescent reporter, SNAP-Cell® 505-Star, simultaneously with an intracellular red fluorescent protein, mCherry. Moreover, we have shown that our construct enables cells to selectively bond to BG-conjugated magnetic …

Mechanics, shape, and programmability in soft matter systems: From fluid membranes to spring and droplet networks
… by which a cell membrane deforms to surround extracellular material to draw it into the cell. Endocytosis in yeast involves clathrin, actin, and Bar proteins. Our model breaks up the process into three stages: (i) initiation, where clathrin interacts with the cell membrane via adaptor …

Comparison between endocytosis and intracanalicular sequestration of cell-surface antigens in human platelets
… exist within the platelet system for uptake of extracellular material as this study dealt exclusively with the platelet response to a specific antibody. These results may have implications with respect to the interaction of platelets with anti-platelet antibodies in the normal state, as well as …

Effect of growth in biofilms upon antibiotic and chlorine susceptibility of Mycobacterium avium and Mycobacterium intracellulare
… cells are protected by layers of other cells and extracellular material (2) and differences in physiologic state of cells as a consequence of growing on surfaces. The objectives of the work were to (1) establish methods for reproducible growth of mycobacterial biofilms (2) measure the formation of …

Characterization of the endothelial cells response to trophoblast debris
… the human placenta constantly extrudes extracellular vesicles into the maternal circulation. This deportation of placental extracellular material creates an extensive feto-maternal interface dispersed around the maternal body and exposes various maternal cells to a large amount of …

The Recycling GTPase, RAB-10, Regulates Autophagy Flux in <i>Caenorhabditis elegans</i>
… organelles. Endocytosis involves the uptake of extracellular material into the cell through the formation of intracellular vesicles termed endosomes. Although both endocytosis and autophagy are interconnected processes, the extent to which endocytic proteins and/or compartments contribute to …

Studies of aquatic micro-organisms in domestic swimming pools
… and Ps.putida, were capable of producing extracellular polymeric substance (EPS). Production of this material has been implicated in the initial adhesion of bacteria, and further, it can act as a barrier against the diffusion of the sanitiser so that organisms exhibit higher levels of …

Monitoring Tissue Function Dynamics in vitro with Bioelectronics: Towards Understanding Barrett’s Oesophagus Pathogenesis
… a poly-electrolyte, is identified as a suitable material upon which to base the platform, as it both allows for highly efficient ionic-to-electronic flux coupling as well as possessing mechanical properties similar to the extracellular material in native tissue. Using an ice-templating technique, …
