Clathrin-mediated endocytosis is the major pathway by which cells internalize materials from the external environment. Dynamin, a large multidomain GTPase, is a key regulator of clathrin-mediated endocytosis. It assembles at the necks of invaginated clathrin-coated pits and, through GTP hydrolysis, catalyzes scission and release of clathrin-coated vesicles from the plasma membrane. Several smal...

objective(s): drug delivery via mucosal routes has been confirmed to be effective in inducing strong immune responses. liposomes could enhance immune responses and mucoadhesive potentials, make them useful mucosal drug delivery systems. coating of liposomes by mucoadhesive polymers succeeded in enhancing immune responses. our studies aim at preparation and characterization of trimethylchitosan-...

statement of the problem: during the orthodontic treatment, microbial plaques may accumulate around the brackets and cause caries, especially in high-risk patients. finding ways to eliminate this microbial plaque seems to be essential. purpose: the aim of this study was to compare the antibacterial effects of nano copper oxide (cuo) and nano zinc oxide (zno) coated brackets against streptococcu...

Hollow Glass Waveguides (HGWs) incorporating single dielectric thin film designs deposited on silver coated silica hollow waveguides have been used for low-loss transmission of infrared radiation in the 2 – 14 micrometer region. Silver iodide has traditionally been the material of choice as a dielectric thin film in HGWs, with other dielectric thin film materials such as cadmium sulfide and lea...

The problem of determining nonlinear neutral inclusions in (electrical or thermal) conductivity is considered. Neutral inclusions, inserted in a matrix containing a uniform applied electric field, do not disturb the field outside the inclusions. The well-known Hashin-coated sphere construction is an example of a neutral inclusion. In this paper, we consider the problem of constructing neutral i...

Ultrahigh-field 27Al MAS and MQMAS NMR and 129Xe NMR were used to characterize the zeolite-coated SBA-15 materials. This study shows evidence that zeolite nanoclusters are coated on the mesopore surface of SBA-15. These techniques are useful for the detection of zeolite nanoclusters and different aluminum environments in zeolite/aluminosilicate composites, which are difficult or even impossible...
