摘要:
The present invention relates to a broad-spectrum tumor suppressor gene and the protein expressed by that gene in appropriate host cells. The protein is a second in-frame AUG codon-initiated retinoblasoma protein of about 94 kD relative molecular mass. The present invention also relates to methods of treating a mammal having a disease or disorder characterized by abnormal cellular proliferation, such as a tumor or cancer and methods of treating abnormally proliferating cells, such as tumor or cancer cells. Treatment is accomplished by inserting a host cell compatible p94.sup.RB expression vector or an effective amount of p94.sup.RB protein into a cell or cells in need of treatment.
摘要:
Compounds and methods are provided for diagnosing, preventing, treating and detecting leishmaniasis infection and stimulating immune responses in patients are disclosed. The compounds disclosed are include polypeptides and fusion proteins that contain at least one immunogenic portion of one or more Leishmania antigens, or a variant thereof. Additionally, methods of screening a screening library for tandem repeat proteins that have immunogenic properties are disclosed. Vaccines and pharmaceutical compositions comprising polynucleotides, polypeptides, fusion proteins and variants thereof that may be used for the prevention and therapy of leishmaniasis, as well as for the detection of Leishmaniasis infection are described.
摘要:
The present invention relates to compositions and methods for selectively expressing a polypeptide in a membrane vesicle. The invention also relates to genetic constructs and recombinant cells suitable to produce such membrane vesicles. This invention also relates to such functionalized membrane vesicles as well as to methods of making antibodies, methods of producing or regulating an immune response as well as to methods of screening or identifying binding partners using the same. The invention more particularly uses lactadherin or portions thereof to selectively express polypeptides in membrane vesicles, of natural or synthetic origin. This invention can be used in experimental, research, therapeutic, prophylactic or diagnostic areas.
摘要:
The strain of micro-organism Lactobacillus fermentum ME-3 is a novel anti-microbial and anti-oxidative probiotic. It has a high anti-microbial effect on Escherichia coli, Shigella sonnei, Staphylococcus aureus, Salmonella typhimurium, and moderate activity against Helicobacter pylori strains. The strain of micro-organism possesses Mn-superoxide dismutase and both its lysates and intact cells have high anti-oxidative activity, increasing the glutathione red-ox ratio in blood sera and able to capture toxic hydroxyl radicals. The strain of micro-organism could be used as a probiotic for the production of functional food (yoghurt, cheese) and non-comestibles (tablets, capsules) for the prophylaxis of intestinal and uroinfections, both for the prevention and treatment of chronic diseases, caused by prolonged oxidative stress.
摘要:
An implantable system is provided that includes: a cell repopulation source comprising genetic material, undifferentiated and/or differentiated contractile cells, or a combination thereof capable of forming new contractile tissue in and/or near an infarct zone of a patient's myocardium; and an electrical stimulation device for electrically stimulating the new contractile tissue in and/or near the infarct zone of the patient's myocardium or otherwise damaged or diseased myocardial tissue.
