279 results about "Cell brain" patented technology

In most cases, neurons are generated by special types of stem cells during brain development and childhood. Neurons in the adult brain generally do not undergo cell division. Astrocytes are star-shaped glial cells that have also been observed to turn into neurons by virtue of the stem cell characteristic pluripotency.

Neuroprotective activity of activated protein c independent of its anticoagulant activity

InactiveUS20070142272A1Enhancing neuroprotectionPromote cell survivalCompound screeningNervous disorderNervous systemInhibitor of apoptosis
Activated protein C (APC), prodrug, and / or a variant thereof may be used as an inhibitor of apoptosis or cell death and / or a cell survival factor, especially for stressed or injured cells or tissues of the nervous system including subjects with neurode-generative disorders. Novel biological functions (e.g., neuroprotection) can be independent or separated from inhibition of clotting or inflammation, and other biological properties of APC (e.g., antithrombotic activity, ability to reduce NFκB-regulated gene expression). It can be used in the treatment of disease or other pathological conditions by at least inhibiting the p53-dependent and / or caspase-3-dependent pro-apoptotic signaling pathways in stressed or injured cells. Thus, APC, prodrugs, and variants thereof (e.g., APC protease domain mutants with reduced anti-coagulant activity) are prototypes of a class of agents for preventing apoptosis or cell death and / or promoting cell survival by direct action on brain cells. New protein C and / or APC variants with reduced anticoagulant activity may be selected thereby.

Sparse Deconvolution Spatial Light Microscopy in Two and Three Dimensions

Methods and a computer program product for applying deconvolution to spatial light interference microscopy for resolution enhancement with respect to the diffraction limit in two and three dimensions. By exploiting the sparsity properties of the phase images, which is prominent in many biological imaging applications, and modeling of the image formation via complex fields, the very fine structures can be recovered which were blurred by the optics. The resolution improvement leads to higher accuracy in monitoring dynamic activity over time. Experiments with primary brain cells, i.e. neurons and glial cells, reveal new subdiffraction structures and motions. This new information can be used for studying vesicle transport in neurons, which may shed light on dynamic cell functioning. Finally, the method may flexibly incorporate a wide range of image models for different applications and can be utilized for all imaging modalities acquiring complex field images.
