Abstract: The present invention discloses a breeding method for obtaining heterosis in lined seahorses, which comprises the following steps: S1, selecting parents of lined seahorse from populations with great differences in genetic background; S2, intensified rearing the parents before pregnancy; S3, matching and breeding the parents of lined seahorse from different geographical populations according to complete diallel cross method; S4, finely nursing pregnant seahorses; S5, respectively collecting all postlarvae (filial generations) hatched by each breeding group in one week; S6, rearing the filial generations; and S7, comparing survival rate and growth performance of filial generations. The present invention, via hybridization of different geographical populations to obtain lined seahorse, makes effective use of heterosis. Survival rate and growth rate of filial generations are apparently enhanced compared to that of those filial generations without hybridization.

Abstract: An method for selective breeding of a fast-growing strain of lined seahorse, including: (1) selecting high-quality lined seahorse parents as a base population for selective breeding; (2) performing prenatal intensified breeding; (3) performing pairing and mating, and rearing the juveniles thereof; (4) performing selective breeding in three junctures with different selection proportions; (5) pairing the saved adult lined seahorses, wherein those with low vitality, having injuries on the body surface, or having a dysplastic brood pouch or gonad are culled, and a selection proportion of 10% for every generation is maintained thereafter; (6) repeating steps (2) through (5) for at least four times to obtain a high-quality strain of lined seahorse with improved weight and body length and stable growth. The method can be used for selective breeding of a new strain with high quality and high yield.

The method comprises: performing gas-liquid micro-hydrocylone separation with ultralow pressure drop on scrubbed flue gas, to remove aerosol particulates entrained in the flue gas; performing gas-liquid micro hydrocyclone separation with ultralow pressure drop on off-gas vented from the top of an absorption column, to remove entrained aerosol particulates; performing gas-liquid micro hydrocyclone separation with ultralow pressure drop on cooled regeneration gas, to remove entrained aerosol particulates; and performing liquid-solid and liquid-liquid two-stage micro-hydrocyclone separation on a mixed amine solution lean for carbon dioxide discharged from regeneration column, to remove entrained solid particulates and machine oil.

Abstract: Provided herein are phenylalanine ammonia-lyase (PAL) variants produced by prokaryotes, wherein such prokaryotic PAL variant has a greater phenylalanine-converting activity and/or a reduced immunogenicity as compared to a wild-type PAL. Further provided are compositions of prokaryotic PAL and biologically active fragments, mutants, variants or analogs thereof, as well as methods for the production, purification, formulation, and use of such compositions for industrial and therapeutic purposes, e.g., treating hyperphenylalaninemia, including phenylketonuria, and other disorders, including cancer.

Abstract: The present invention relates to naphthylurea derivatives. Such substances can significantly inhibit VEGFR2 and PDGFR-? receptor tyrosine kinase phosphorylation at nanomolar concentration levels. It is a novel type of tyrosine kinase inhibitors which can be used in the treatment of tyrosine kinase-mediated diseases or symptoms such as malignancies and ocular diseases accompanied with pathologic neovascularization.

Abstract: A process and an apparatus for separating and recovering waste alkali from a cyclohexane oxidation solution are provided. A gradient combination of the gravity separation technique, the vortex separation technique and the coalescence separation technique is used to carry out fine separation of the waste alkali liquor from the cyclohexane oxidation solution. The purified cyclohexane oxidation solution is fed into a down-stream apparatus. Most of the waste alkali liquor thus separated is recycled, while the remaining is expelled. The expelled waste alkali liquor is incinerated in an incinerator, followed by recovering the molten species using a pneumatic pulverization process.
