Isolated, mammalian, adult bone marrow-derived, lineage negative hematopoietic stem cell populations (Lin− HSCs) contain endothelial progenitor cells (EPCs) capable of rescuing retinal blood vessels and neuronal networks in the eye. Preferably at least about 20% of the cells in the isolated Lin− HSCs express the cell surface antigen CD31. The isolated Lin− HSC populations are useful for treatment of ocular vascular diseases. In a preferred embodiment, the Lin− HSCs are isolated by extracting bone marrow from an adult mammal; separating a plurality of monocytes from the bone marrow; labeling the monocytes with biotin-conjugated lineage panel antibodies to one or more lineage surface antigens; removing of monocytes that are positive for the lineage surface antigens from the plurality of monocytes, and recovering a Lin− HSC population containing EPCs. Isolated Lin− HSCs that have been transfected with therapeutically useful genes are also provided, and are useful for delivering genes to the eye for cell-based gene therapy. Methods of preparing isolated stem cell populations of the invention, and methods of treating ocular diseases and injury are also described.

The invention relates to a method for producing triglyceride type docosahexenoic acid fat by industrially fermenting schizochytrium. The method comprises the following step: the docosahexenoic acid fat is prepared by fermenting the schizochytrium taken as the strain with the a culture medium with microelements; wherein the culture medium with the microelements comprises a carbon source, a nitrogen source, inorganic salt and microelements, and the microelements comprise at least one of biotin, chlorophyll, beta-carotene, vitaminB1, vitaminB6 and vitaminB12. The prepared docosahexenoic acid fat does not need to be further chemically modified and can be directly used by people needing DHA, including infants, pregnant women, breast feeding women or patients who suffer from diseases due to insufficient DHA and need to supplement DHA. The invention has the advantages of high DHA content, high purity, safe and reliable quality, low production cost, stable production and almost no EPA; and the environmental-friendly, safe and high-content triglyceride type DHA fat can be produced with low cost at a large scale.

A method for treating Type II diabetes by administering to an affected individual a combination of chromic tripicolinate and biotin. The two compounds are administered orally or parenterally at in daily dosages which provide between 50 and 1,000 mu g of chromium and between 25 mu g and 200 mg biotin, the amounts of chromium and biotin being selected together to provide a greater than additive effect.

A method for inspecting hepatitis and AIDS nucleic acid by synchronized amplification and its reagent knit are disclosed. The process is carried out by taking magnetic ball as automatic medium, specific synchronized capturing HBV, CHV and HIV nucleic acid, accelerating biotin primer construction and purification by RNA external label and internal label, real-time synchronized inspecting and T-PCR amplifying based on Tagman probe. The reagent knit consists of dis-inhibitor, cracking liquid, magnetic ball suspension, washing liquor, internal check, RT-PCR reactive liquor, enzyme mixture, fluorescent mixture, positive check and negative check. It's accurate and automatic, has single-tube operation, closed inspection AND synchronized extraction, and it has better sensitivity and specific performance and can be used for large-scale blood screening and large-capacity clinical inspection.

The invention provides methods and compositions for the rapid and sensitive detection of post-translationally modified proteins, and particularly of those with post-translational glycosylations. The methods can be used to detect O-GlcNAc post-translational modifications on proteins on which such modifications were undetectable using other techniques. In one embodiment, the method exploits the ability of an engineered mutant of β-1,4-galactosyltransferase to selectively transfer an unnatural ketone functionality onto O-GlcNAc glycosylated proteins. Once transferred, the ketone moiety serves as a versatile handle for the attachment of biotin, thereby enabling detection of the modified protein. The approach permits the rapid visualization of proteins that are at the limits of detection using traditional methods. Further, the preferred embodiments can be used for detection of certain disease states, such as cancer, Alzheimer's disease, neurodegeneration, cardiovascular disease, and diabetes.
