In the study we formulated the serratiopeptidase loaded cholic acid conjugated and unconjugated chitosan mucoadhesive microspheres. It was observed that the conjugated microspheres show better permeation rate than unconjugated microspheres. Moreover the permeation enhancer increased the % cumulative drug permeation through the mucosal membrane from 69.37 % to 74.39 % for unconjugated microspher...

ultimate limits of an open pit, which define its size and shape at the end of the mine’s life, is the pit with the highest profit value. a number of algorithms such as floating or moving cone method, floating cone method ii and the corrected forms of this method, the korobov algorithm and the corrected form of this method, dynamic programming and the lerchs and grossmann algorithm based on grap...

Tungsten trioxide microspheres of 2–4 m diameter have been prepared by controlled oxidation of tungsten carbide microspheres. These microspheres are characterized by XRD, SEM, and HRTEM. The microspheres are made of WO3 nanoparticles with an average diameter of around 15 nm. Platinum supported on these WO3 microspheres exhibits higher and stable electrocatalytic activity for methanol oxidation ...

the cellular therapy and nerve tissue engineering will probably become a major therapeutic strategy for promoting axonal growth through injured area in central nervous system and peripheral nervous system in the coming years. the stem cell carrier scaffolds in nerve tissue engineering resulted in strong survival of cells and suitable differentiation into neural cells, so this pathway should be ...

A series of chitosan/attapulgite (CTS/APT) hybrid microspheres were prepared by a facile spray-drying technique. The developed hybrid microspheres were characterized by Fourier transform infrared spectra (FTIR), X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and the zeta potential. The encapsulation efficiency and in vitro controlled release properties of the microspheres fo...

One of the key advantages to a lab-on-a-chip system based on digital microfluidics is the reconfigurability and reusability of the same chip for different tasks. The ability to manipulate magnetic microspheres in solution on a lab-on-a-chip will expand the variety of tasks that can be performed if the microspheres are used as reagent immobilization surfaces. Because the microspheres can be tran...

An investigation into the suitability of mucuna gum microspheres for oral delivery of glibenclamide is presented. Mucuna gum microspheres were formulated under different conditions of polymer concentration and crosslinking time at constant speed. The formulated microspheres were thereafter loaded with glibenclamide by the remote loading process. The microspheres were evaluated according to part...
