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...

Kerr optical frequency combs (OFCs) based on silica microsphere whispering gallery mode resonator (WGMR) have various applications where they are used as a light source. For telecommunication purposes, WGMR-based Kerr-OFC comb generators can be physically realized using resonators and to replace multiple laser arrays. In such realization, these novel sources the potential demonstrate an attract...

PURPOSE To standardize the indications, techniques, multimodality treatment approaches, and dosimetry to be used for yttrium-90 (Y90) microsphere hepatic brachytherapy. METHODS AND MATERIALS Members of the Radioembolization Brachytherapy Oncology Consortium met as an independent group of experts in interventional radiology, radiation oncology, nuclear medicine, medical oncology, and surgical ...

The release process of phenol blue from a dibutyrylchitin microsphere, prepared with chitin from a silkworm, into an aqueous solution was kinetically analyzed by single microparticle injection/manipulation and absorption microspectroscopy. The distribution ratio and the release rate of phenol blue in the single microsphere/water system were significantly influenced by the pH of the solution. Th...

In this paper, we have proposed a shell type dielectric microsphere resonator in order to enhance its quality factor. In this work we have assumed that the radius of dielectric microsphere is 12μm and that the interior metal layer radius is 11.5μm. We have obtained analytic equations for Vector potentials, characteristic equation, quality factor, resonance frequency and resonance location of TE...

Optical whispering gallery mode microresonators with controllable parameters in the telecommunication range are demanded for diverse applications. Controlling group velocity dispersion (GVD) is an important problem, as near-zero GVD a broad wavelength could contribute to development of new microresonator-based light sources. We demonstrated theoretically tailoring SCL-band combination free-spec...

The microsphere model and the continuous withdrawal of arterial blood have been commonly used in clinical studies when measuring regional cerebral blood flow (rCBF) by N-isopropyl-p[123I]iodoamphetamine (IMP) SPECT. The method is considered to underestimate rCBF because of the washout of the tracer from brain tissue with increasing time after injection; however, the extent of this underestimati...
