We investigate the scattering of polychromatic plane light wave incident upon a system formed with two anisotropic particles in different distance. The analytical expression for the spectrum of the scattered field is derived. Numerical examples show the phenomena of spectral shifts and spectral switches of the scattered field. The influences of the scattering direction and the difference of the particles on the spectral switch are illustrated. © 2013 Optical Society of America. Source

FAM110C belongs to a family of proteins that regulates cell proliferation. In the present study, the spatiotemporal expression pattern of FAM110C and its potential role were examined during the periovulatory period. Immature female rats were injected with equine chorionic gonadotropin (eCG) followed by human chorionic gonadotropin (hCG) and ovaries or granulosa cells were collected at various times after hCG administration (n = 3/time point). Expression levels of Fam110c mRNA and protein were highly induced both in intact ovaries and granulosa cells at 8 to 12 h after hCG treatment. In situ hybridization analysis demonstrated Fam110c mRNA expression was induced in theca and granulosa cells at 4 h after hCG, primarily localized to granulosa cells at 8 h and 12 h, and decreased at 24 h after hCG. There was negligible Fam110c mRNA detected in newly forming corpora lutea. In rat granulosa cell cultures, hCG induced expression of Fam110c mRNA was inhibited by RU486, whereas NS398 and AG1478 had no effect, suggesting that Fam110c expression is regulated in part by the progesterone receptor pathway. Promoter activity analysis revealed that an Sp1 site was important for the induction of Fam110c expression by hCG. Overexpression of FAM110C promoted granulosa cells to arrest at the G(1) phase of the cell cycle but did not change progesterone levels. In summary, hCG induces Fam110c mRNA expression in granulosa cells by activation of an Sp1-binding site and the actions of progesterone. Our findings suggest that FAM110C may control granulosa cell differentiation into luteal cells by arresting cell cycle progression. Source

This review focuses on classifying different types of long wavelength absorbing BODIPY dyes based on the wide range of structural modification methods that have been adopted, and on tabulating their spectral and photophysical properties. The structure-property relationships are analyzed in depth with reference to molecular modeling calculations, so that the effectiveness of the different structural modification strategies for shifting the main BODIPY spectral bands to longer wavelengths can be readily compared, along with their effects on the fluorescence quantum yield (ΦF) values. This should facilitate the future rational design of red/NIR region BODIPY dyes for a wide range of different applications. © 2014 The Royal Society of Chemistry. Source

The observation of the stereochemistry of silicon-stereogenic silanes dates back to the pioneering work by Kipping in 1907.[1] However, despite many significant efforts in the past hundred years toward finding new synthetic methodologies to Si-stereogenic silanes, they are still few in number. The enantioselective preparation of these silanes and their functionalized derivatives was not at all a trivial task and remained restricted to optical and kinetic resolution.[1c,d, 2] Undoubtedly, the exploration of new and efficient catalytic methods with high enantioselectivity remains one of the principal challenges in asymmetric catalysis. © 2012 Wiley-VCH Verlag GmbH & Co.

Ordered mesoporous inorganic non-oxide materials attract increasing interest due to their plenty of unique properties and functionalities and potential applications. Lots of achievements have been made on their synthesis and structural characterization, especially in the last five years. In this critical review, the ordered mesoporous non-oxide materials are categorized by compositions, including non-oxide ceramics, metal chalcogenides, metal nitrides, carbides and fluorides, and systematically summarized on the basis of their synthesis approaches and mechanisms, as well as properties. Two synthesis routes such as hardlating (nanocasting) and softlating (surfactant assembly) routes are demonstrated. The principal issues in the nanocasting synthesis including the template composition and mesostructure, pore surface chemistry, precursor selection, processing and template removal are emphatically described. A great number of successful cases from the softlating method are focused on the surfactant liquid-crystal mesophases to synthesize mesostructured metal chalcogenide composites and the inorganic-block-organic copolymer self-assembly to obtain non-oxide ceramics (296 references). © 2011 The Royal Society of Chemistry.
