Preparation of chitosan (CS) microspheres as a novel drug delivery vehicle for intranasal immunization using high, medium and low CS molecular weight (MW) was investigated in this study. Diphtheria toxoid (DT) was used as a model antigen. The emulsion-solidification method was adopted for microencapsulation of DT. In the first step, following the purification of semi-crude DT by the ion-exchan...
the objective of the present study was to develop floating microspheres of cefpodoxime proxetil in order to achieve an extended retention in the upper git, which may result in enhanced absorption and thereby improved bioavailability. the microspheres were prepared by non-aqueous solvent evaporation method using polymers such as hydroxyl propyl methyl cellulose (hpmc k 15 m), ethyl cellulose in ...
Developing a living prosthetic breast to inhibit potential cancer recurrence and simultaneously promote reconstruction would be promising strategy for clinical treatment of after mastectomy. Here, in the form injectable gelatin methacryloyl microspheres is prepared, where they encapsulated zeolitic imidazolate framework (ZIF) nanoparticles loaded with small molecules urolithin C (Uro-C) adipose...
Background: Radioactive yttrium glass microspheres are used for liver cancer treatment. These yttrium aluminum silicate microspheres are synthesized from yttrium, aluminum and silicone oxides by melting. There are two known processes used to transform irregular shaped glass particles into microspheres, these ‘spheroidization by flame’ and ‘spheroidization by gravitational fall...
one small-scale double emulsion technique for incorporation of naja- naja oxiana venom into poly (lactide-co-glycolide) (plga) microspheres were developed and optimized. the effects of high speed homogenization on the double emulsion stability, microsphere size, entrapment efficiency and in vitro release of venom were studied. a stable double emulsion was verified by homogenization method. slow...
Purpose: To evaluate the degree of fibroid infarction after uterine fibroid embolization (UFE) with tris-acryl gelatin microsphere (Embosphere) visualized by contrast-enhanced magnetic resonance imaging (MRI) and evaluation of the clinical outcome measured with symptom and quality of life questionnaire (UFS-QOL) after 3 months follow-up. Materials and Methods: A prospective study included twent...
Interleukin (IL)-10 is an anti-inflammatory cytokine that suppresses the T helper 1 immune response and down-regulates macrophages and monocytes. The therapeutic effect of systemic administration of IL-10 for patients with inflammatory bowel disease, however, has not been satisfactory. We examined whether rectal administration of gelatin microspheres (GM) containing IL-10 (GM-IL-10) prevents co...
