For long distance orbital angular momentum (OAM) based transmission, the conventional whole beam receiving scheme encounters the difficulty of large aperture due to the divergence of OAM beams. We propose a novel partial receiving scheme, using a restricted angular aperture to receive and demultiplex multi-OAM-mode beams. The scheme is theoretically(More)
Heat shock proteins (Hsps) are thought of as chaperones of morphologic development of cells and organisms, and believed to be closely related to normal and abnormal embryonic development. Previous studies only focused on a small number of HSPs and their relationships with embryogenesis, and roles of most HSPs in normal and abnormal embryonic development(More)
Rat ovarian follicle culture, as a novel bioassay, is adopted in this study to explore the effects of cadmium chloride (CdCL(2)) on folliculogenesis and oocyte maturation in vitro; the feasibility for its application on detection of possible effects of chemicals on reproduction is discussed and evaluated as well. The results showed that follicle growth,(More)
OBJECTIVE To use rat preantral follicle culture as a novel bioassay in order to study the effects of di-2-ethylhexyl phttmlate (DEHP) and its metabolite mono-2-ethylhexyl phthalate (MEHP) on folliculogenesis in vitro. METHODS The preantral follicles were mechanically dissected from ovaries and equally randomized to to 96-well plates. Six dose groups were(More)
Emerging applications based on optical beams carrying orbital angular momentum (OAM) will probably require photonic integrated devices and circuits for miniaturization, improved performance, and enhanced functionality. We demonstrate silicon-integrated optical vortex emitters, using angular gratings to extract light confined in whispering gallery modes with(More)
Various biochemical and physiological stimuli may interfere with endoplasmic reticulum (ER) homeostasis, causing aggregation and accumulation of unfolded or malfolded proteins in the ER and resulting in ER stress (ERS), and the ER attenuates ERS through unfolded protein response (UPR). All-trans-retinoic acid (ATRA) can enhance or attenuate some ERS-induced(More)
It is reported that salidroside, the main component of a traditional Chinese medicine, Rhodiola rosea, has the efficacy of protecting Coxsackie virus impairment. As part of a safety evaluation on salidroside for use in the treatment of viral myocarditis, the present study evaluated potential genotoxicity of salidroside by using the standard battery of tests(More)
The ability to rapidly switch between orbital angular momentum modes of light has important implications for future classical and quantum systems. In general, orbital angular momentum beams are generated using free-space bulk optical components where the fastest reconfiguration of such systems is around a millisecond using spatial light modulators. In this(More)
Most previous studies focused on a small number of heat shock proteins (Hsps) and their relationships with embryogenesis, and the actual roles of these Hsps in normal and abnormal embryonic development remain unclear. It was found in the present systemic study that except for Grp170, whose expression was not detectable at GD18, all 19 Hsps of Hsp70, Hsp90(More)
The generation of light beams carrying orbital angular momentum (OAM) has been greatly advanced with the emergence of the recently reported integrated optical vortex emitters. Generally, optical vortices emitted by these devices possess cylindrically symmetric states of polarization and spiral phase fronts, and they can be defined as cylindrical vector(More)
