Although much evidence suggests that the plasma membrane of eukaryotic cells is not homogenous, the precise architecture of this important structure has not been clear. Here we use transmission electron microscopy of plasma membrane sheets and specific probes to show that most or all plasma membrane-associated proteins are clustered in cholesterol-enriched domains ("islands") that are separated...
As the smart grid develops rapidly, abundant connected devices offer various trading data. This raises higher requirements for secure and effective data storage. Traditional centralized management does not meet above requirements. Currently, with conventional consortium blockchain can solve issues. However, in face of a large number nodes, existing consensus algorithms often perform poorly term...
در پروژه حاضر، ابتدا نانوذرات کروی mcm-41 تهیه شده است. نانوذرات تهیه شده با دارا بودن مساحت سطح ویژه بالا و همچنین خلل و فرج های منظم در ساختار مورد استفاده قرار گرفت. نانوذرات کروی mcm-41 با اصلاح کننده های مناسب اصلاح شد. در تهیه نانوکامپوزیت پلی استایرن از سه نوع نانوذره mcm-41 استفاده شد. محصول گونه اول، نانوذره mcm-41 همراه با استایرن، پراکنشی از نانوذره mcm-41 در ماتریس پلیمری به روش پلی...
This study presents a new approach for physical and material modeling of space frame-raft-soil system. The physical modeling consists of a modified Thimoshenko beam bending element with six degrees of freedom per node to model the beams and columns of the superstructure, a modified Mindlin's plate bending element with five degrees of freedom per node to represent the structural slabs and raft, ...
Lateral assemblies of glycolipids and cholesterol, "rafts," have been implicated to play a role in cellular processes like membrane sorting, signal transduction, and cell adhesion. We studied the structure of raft domains in the plasma membrane of non-polarized cells. Overexpressed plasma membrane markers were evenly distributed in the plasma membrane. We compared the patching behavior of pairs...
Anemia remains the principal management challenge for patients with lower risk Myelodysplastic Syndromes (MDS). Despite appropriate cytokine production and cellular receptor display, erythropoietin receptor (EpoR) signaling is impaired. We reported that EpoR signaling is dependent upon receptor localization within lipid raft microdomains, and that disruption of raft integrity abolishes signalin...
