摘要:
The present invention relates to carbohydrate-specific peptides, which have a strong affinity and preparation method thereof. Particularly, the present invention relates to carbohydrate-specific peptides, which have been developed to have an increased strong affinity to carbohydrates by the multiple combinations of peptides having carbohydrates-specific amino acid sequences and preparation method thereof. Carbohydrate-specific peptides of the present invention have a very strong affinity under micromol, so that they can shut off recognition between cells transferred by specific carbohydrates, which means they can be used for the treatment of diseases mediated by recognition between cells and used as a diagnostic kit which diagnoses diseases by confirming the existence of any specific carbohydrate.

The present invention relates to heterodimeric conjugates of neomycin-chloramphenicol of formula 1, their preparation and their use. Because of their heterodimeric structure, they can recognize both stem and loop of RNA motif and show binding ability to a certain RNA such that they have an enhanced pharmaceutical efficacy and reduced side effect which can be caused by non-specific drugs. For these reasons, the can be effectively used as an antiviral agent, an antibacterial agent or an anti cancer drugs.

The present invention relates to apolipoprotein A-1 mimic peptides, and therapeutic agent for treating hyperlipidemia and diseases related to hyperlipidemia comprising the same. More specifically, the apolipoprotein A-1 mimic peptides of the present invention were manufactured by modifying hydrophilic or hydrophobic face of existing 4F amphipathic peptides to produce Apo A-I mimic peptides which specifically bind with cholesterol ester to allow high density lipoprotein content to increase, and the peptide of which phenylalanine in hydrophobic face of 4F is substituted with 2-naphthylalanine has superior cholesterol efflux capability and cognitive function for lipids to the existing 4F peptides, among the mimic peptides. Thus, the Apo A-I mimic peptides of the present invention can be used as Apo A-I mimic peptides and as a therapeutic agent for treating hyperlipidemia and diseases related to hyperlipidemia.

The present invention provides a digital imaging photodetector with a gas electron multiplier. The digital imaging photodetector comprises a gas electron multiplier detector. The gas electron multiplier detector includes a photoelectric converter for converting incident light into photoelectrons or Compton electrons; a gas electron multiplier (GEM) for receiving the photoelectrons or Compton electrons from the photoelectric converter and multiplying them; and a readout unit for receiving an electrical signal indicating a position where an electron cloud multiplied in the gas electron multiplier arrives on an anode, recognizing coordinates of the electron cloud based on the received signal, and outputting the coordinates of the electron cloud. According to the digital imaging photodetector of the present invention, real-time imaging of image information can be achieved by multiplying photoelectrons or Compton electrons, which are discharged due to a photoelectric effect or a Compton effect induced by visible rays, ultraviolet rays or X-rays, using the gas electron multiplier.
