178 results about "Hematinic" patented technology

A hematinic is a nutrient required for the formation of blood cells in the process of hematopoiesis. The main hematinics are iron, B12, and folate. Deficiency in hematinics can lead to anaemia. In cases of hematinic deficiency, hematinics can be administered as medicines, in order to increase the hemoglobin content of the blood.

Recombinant multivalent viral vaccine

The present invention relates to multivalent recombinant raccoon poxviruses, containing more than one exogenous gene inserted into either the thymidine kinase gene, the hemagglutinin gene, or a combination thereof. Disclosed is the use of the multivalent recombinant raccoon poxviruses as vaccines to immunize felines against subsequent challenge by feline pathogens. Also disclosed is a method of making a multivalent recombinant raccoon poxvirus by a recombination process involving the construction of an insertion vector into which the exogenous genes are inserted, and flanking the inserted genes are sequences which can recombine into the raccoon poxvirus thymidine kinase gene, or the hemagglutinin gene, or a combination thereof; introducing both the insertion vector containing the exogenous genes, and raccoon poxvirus into susceptible host cells; and selecting the recombinant raccoon poxvirus from the resultant plaques.

Iron supplementary liposome iron and method of preparing the same

The invention relates to a liposomal iron prepared as a novel iron-supplementing agent by a rotary film ultrasonic method. The liposomal iron is prepared from heme iron and / or inorganic iron, cholesterol and lecithin at a weight ratio of (0.1-200):(1-10):(10-100) by dispersing lecithin, and cholesterol ethanol solution into iron solution containing PBS under a specific condition. The inventive liposomal iron iron-supplementing agent has no toxicity or immunogenicity, has targeting ability, and can be used as pharmaceutical carrier. Clinically, the liposomal iron iron-supplementing agent can reduce drug dose, improve absorption efficiency, reduce toxicity, remarkably improve the solubility and stability of heme iron, and improve bioavailability. The rotary film ultrasonic method can obtain liposome with high encapsulation efficiency, can effectively remove organic (ethanol) residues, and has the advantages of easily controlled process conditions and simple operation.

Structure and application of influenza virus hemagglutinin protein binding polypeptide

Belonging to the technical field of biomedicine, the invention relates to a sequence and structure of a polypeptide able to specifically bind with influenza virus hemagglutinin protein, and application of the polypeptide in anti-influenza viruses. By expressing purified influenza virus hemagglutinin protein and screening a random peptide library with a phage display technology, a polypeptide specifically bound with influenza virus hemagglutinin and equipped with sequences numbered 1-18 can be obtained. As a hemagglutinin-binding peptide can hinder the combination of hemagglutinin and a host cell receptor, so the influenza virus can be inhibited from infecting the host cell. Thus, the invention also conducts an anti-influenza virus activity study to the hemagglutinin-binding peptide selected from the phase peptide library, and finds that a polypeptide H17, with a sequence of NH2-SHGRITFAYFAN-COOH, can effectively inhibit the influenza virus from infecting the host cell and is of small toxicity. Therefore, the hemagglutinin-binding peptide of the invention and the H17 polypeptide therein with an anti-influenza virus activity are expected to become novel treatment medicaments for treating diseases caused by influenza virus infection and reducing the hazards of diseases caused by influenza viruses.
