ABSTRACr In an open, randomised crossover study enteric coated microspheres of pancreatin were compared with a standard preparation of enteric coated pancreatin over two consecutive 28 day treatment periods in 23 adults with steatorrhoea due to cystic fibrosis. Lipase intake was equal to the patients' previous requirements and was the same during the two months. Patients performed 72 hour faeca...

We experimentally demonstrate controlled polarization-selective phenomena in a whispering gallery mode resonator. We observed efficient ( approximately 75%) polarization conversion of light in a silica microsphere coupled to a tapered optical fiber with proper optimization of the polarization of the propagating light. A simple model treating the microsphere as a ring resonator provides a good f...

Density of 15-microm microspheres after left atrial application is the standard measure of regional perfusion. In the heart, substantial differences in microsphere density are seen at spatial resolutions <5 ml, implying perfusion heterogeneity. Microsphere deposition imaging permits a superior evaluation of the distribution pattern. Therefore, fluorescent microspheres (FMS) were applied, FMS de...

background: different methods have been used for bcg vaccination. alginate microspheres are useful in delivery of vaccines to the gastrointestinal tract by oral route. objective: to compare the immune response following oral microencapsulated and subcutaneous (sc) route administration of bcg vaccine in balb/c mice. methods: alginate microspheres were produced by an internal emulsification metho...

The preparation of monodisperse azobenzene (Azo) polymer microspheres by dispersion polymerization was reported. photo-induced fusion Azo successfully achieved during the process reversible trans-cis-trans photoisomerization units, and induced various unique “microsphere molecular” clusters or polymers”. Encouraged this interesting phenomenon, microsphere different topological structures were s...

a water–soluble gelatin combined with polyethylene microspheres were developed to prepare alumina composite foam. gelatin was used as the gelling agent and polyethylene was used as pore making template. on the other hand, kaolin was used to provide green strength and cuo was applied to decrease the required temperature as a sinter aid. alumina bodies need elevate temperature for sintering, incr...

the purpose of the research was to formulate microspheres of acyclovir (acv) using mucoadhesive polymers, sodium alginate and chitosan. calcium chloride was used as the ionotropic gelling agent. sodium alginate was crosslinked by calcium chloride leading to a slower release of the drug. chitosan which is a cationic polymer interacted with sodium alginate, an anionic polymer, to form an interpol...

BACKGROUND Revascularization of the heart after myocardial infarction (MI) using growth factors delivered by hydrogel-based microspheres represents a promising therapeutic approach for cardiac regeneration. Microspheres have tuneable degradation properties and support the prolonged release of soluble factors. Cardiac patches provide mechanical restraint, preventing dilatation associated with ve...

Photonic jets (PJs) obtained by illuminating a dielectric microsphere have recently shown to provide an efficient and cost‐effective means of laser‐writing localizing single‐photon emitters with sub‐diffraction precision. The fabrication technique relies on the photoinduced formation GaAsN quantum dots (QDs) that are self‐aligned microsphere, which in turn enhances collection efficiency their e...

Novel materials synthesis techniques were used to fabricate nanostructured and macroporous semiconducting metal oxide (SMO) films exhibiting exceptionally high sensitivity to reducing and oxidizing gases, as compared to conventionally prepared specimens. Increased sensitivity resulted from an elevated surface area and reduced specimen cross section. Several processing routes were pursued includ...
