Centipede alga（Grateloupia filicina）, a kind of Marine red algae, whichbelongs to Rhodophyta, Florideae, Cryptonemiales, Halymeniaceae, is Widelydistributed all over the coastal warm temperate zone in the world. Polysaccharide, theimportant main component in centipede alga, has shown several biological activefunctions such as antiangiogenic, antivirus, Antitumor, anticoagulant, anti-thrombotic,anti-fatigue and hypoxia. At present the relevant research report about [...]
Sophora alopecuroides L.,a wild and herbaceous leguminous plant of Sophora,is widelydistributed in the northwest region of Gansu、Ningxia、Xinjiang of China, which is good forwind prevention and sand-fixation and improving salt-alkali soil,has a very important role inprotecting environment.

BackgroundThe C-type lectin-like receptors such as NKG2Dand CD94/NKG2emerged as a new category of Tcell costimulatory molecules due to their demonstrated ability to costimulate T cell proliferation andcytokine secretion. The C-type lectin family is characterized by carbohydrate recognition domain (CRD).Their CRD domains are named C-type lectin-like domain (CTLD).Experiments has showing that C-type lectin-like molecules, including NK [...]
Onconase is the current global mainly one of100new drugs and have very strong killerfunction to a wide variety of tumor of body inside and outside because of its nuclease low andcell toxicity strong,, Therefore, the paper constructs pPIC9K-rrONC expression vector. WithGS115pichia pastorios for receptor, extracted engineering strains from restructuring yeast canexpress correctly rrONC. Then the [...]

As the first important line of defense, human skin which against externalattacks played an important role in the evolution of human development.However, due to long exposure in the environment, human skin is one of themost disease-prone sites. Among these multiple diseases, infections caused bypathogenic microorganisms are undoubtedly the most serious, and along with theabuse of [...]
Objective:In order to increase the yield of Natrin and purify it, chromatography was used to purify Natrin from Guangxi Cobra Venom,which was subsequently investigated about its growth inhibitory function on human tumour cells.Methods:(1) The crude snake venom was separated and purified by gel filtration on a Sephadex G-75colum and CM-Sepharose CL-6B cation-exchange column, and the [...]
