1. MicroRNAs (miRNAs), the small non-coding RNAs of approximately 22 nucleotides, are now recognized as a very large family present throughout the genomes of plants and metazoans. These small transcripts modulate protein expression by binding to complementary or partially complementary target protein-coding mRNAs and targeting them for degradation or(More)
Secret sharing plays an important role in protecting important information from getting lost, destroyed, or into wrong hands. In 2000, Chien et al. proposed a (t, n) multi-secret sharing scheme. In 2004, Yang et al. proposed an alternative scheme based on Shamirpsilas secret sharing. In the next year, Pang et al. took another approach to share multiple(More)
We study the band structures of one-dimensional (1D) photonic crystals (PCs) in the subwavelength limit. A "spatial-averaged single-negative" (SASN) gap whose edges correspond to zero (volume) averaged permittivity (epsilon=0) and zero (volume) averaged permeability (micro=0) will appear when metamaterial is included in the PC. Unlike the Bragg gap, the(More)
The Dirac point (DP) with a double-cone structure for optical fields can be realized in optically homogenous media. The condition for the realization of DP in optical systems is the varying of refractive index from negative to zero and then to positive. Our analysis verify that, similar to electrons in graphene, the light field near DP possesses of the(More)
BACKGROUND Previous studies suggested that platelet-activating factor (PAF) plays an important role in ischemic diseases. Apoptosis has been implicated in myocardial infarction-related cell death. The present study was designed to determine whether PAF could induce apoptosis in cardiac myocytes and the underlying mechanisms by which PAF causes apoptosis. (More)
To explain how individuals' self-perceived long-term mate value influences their mate preference and mate choice, two hypotheses have been presented, which are "potentials-attract" and "likes-attract", respectively. The potentials-attract means that people choose mates matched with their sex-specific traits indicating reproductive potentials; and the(More)
Severe acute respiratory syndrome (SARS) is a recently discovered viral disease, characterized by fever, cough, acute fibrinous pneumonia and high infectivity. Specific pathogen-free (SPF) chickens were immunized with inactivated SARS coronavirus and their eggs were harvested at regular intervals. Yolk immunoglobulin (IgY) was extracted using the water(More)
