Findings advance use of adult stem cells for replacement bone
...rs at Rice University have discovered a new way to culture adult stem cells from bone marrow such that the cells themselves produce a growth matrix that is rich in important biochemical growth factors. The research, which appears online this week in the Proceedings of the National Academy of Sciences, is not...New infectious agents pose new risks for people with bleeding disorders, Jefferson hematologist says
...enes for clotting factors in the laboratory tissue culture dish lessen the likelihood of contamination by infectious agents. "There will always be emerging pathogens and we won't always know what they are," says Dr. Siegel, who is director of the Hemophilia Center at Thomas Jefferson University Hospital.

...am found that adding APOE to neurons in laboratory culture blocked NMDA receptors. In this study, they confirmed through a series of experiments that the receptors for APOE and NMDA interacted, and that the protein that linked the two was PSD95, often found in neural synaptic junctions.

...selves into new strains. By co-infecting cells in culture with the WC3 strain of rotavirus and five different human rotavirus strains known as G1, G2, G3, G4, and P1, the scientists were able to create a reassortant bovine-human rotavirus virus that promised improved protection against rotavirus disease.

But almost 10 per cent of women and just over 11 per cent of men tested positive, using NAAT. The increase equates to a 62 per cent jump in positive results for wom...JCI table of contents, January 26, 2006
