Porous microcarriers were fabricated from synthesized poly(γ-benzyl-L-glutamate) (PBLG) polymer to engineer adipose tissue with lobule-like structure via the injectable approach. The adipogenic differentiation of human adipose-derived stem cells (hASCs) seeded on porous PBLG microcarriers was determined by adipogenic gene expression and glycerol-3-phosphate dehydrogenase enzyme activity. In vit...

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 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 ...

We analyze second order parametric processes in a silica microsphere coated with radially aligned nonlinear optical molecules. In a high-Q nonlinear microsphere, we discover that it is possible to achieve ultralow threshold parametric oscillation that obeys the rule of angular momentum conservation. Based on symmetry considerations, one can also implement parametric processes that naturally gen...

We demonstrate a low-threshold microsphere laser on a silicon chip, fabricated from erbium-doped silica sol–gel film. Single-longitudinal mode lasing emission is observed from a 37 μm diameter microsphere cavity with an erbium ion concentration of 2× 1019 cm−3. The measured lasing threshold of the silica microsphere laser is as low as 4.8 μW. (Some figures may appear in colour only in the onlin...

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...

currently much debate, attention and concern surrounds the use of genetically modified plants or animals. but there has not been much concern about microorganisms, although we all are aware of the place of microorganisms in the circle of life, their abundance and diversity. there are many examples regarding the application of genetically engineered microorganisms (gems), however, like other hig...
