Methods and systems for the treatment for ALS incorporating stem cells harvested from the subject to be treated. These stem cells may be genetically altered with the addition of several genes of interest. Then, the patient will receive systemic gene therapy for the muscles and directed specifically at motor neurons. In this multi-pronged treatment approach, the stem cells provide immune regulation and the regeneration of motor neurons. And, the new motor neurons carry the added genes, which are protective against motor neuron death from ALS. The systemic therapy increases the amount of genes, which further reduces the effects of ALS. Additional gene therapy administered in the muscle will be further protective of the axon, while maintaining muscle mass and function.

Synthetic Stem Cell-like Tissue Healing and Regeneration Medication with Anti-inflammatory, Protein Synthesis, Enzyme Deficiency Activation and Genetic Therapy, and Anti-cancer Agent derived from a series of inventions that include these products of Biomolecular Engineering, Drug Discovery from a Biologic Periodic Table of Applied Biochemistry and Biophysics. Tissue has a self healing effect promoting tissue healing and tissue regeneration. Not only does it maintain good health but also it has been observed that the patient's blood is withdrawn from the patient and applied to the ulcer has healing qualities. Cartilage placed in a wound promotes and accelerates wound healing. The anabolic biochemical and biophysical equivalent of tissue has been found in these embodiments to have the same pharmacologic qualities, when devoid of genetic DNA mismatch and other catabolic factors including the catabolic effects of microorganism overgrowth that lacks pro-biotic qualities. The healing efficacy of these tissue components gives us further appreciation of the protective action of human tissue over and above and other than the immune protective system or perhaps an integral component part of the immune system.

The present invention provides a new approach for cancer treatment by utilizing gene therapy combined with radiation therapy to enhance cytotoxicity in malignant cells. Specifically, the present invention demonstrates that molecular chemotherapy with the cytosine deaminase gene and 5-fluorocytosine is an effective radiosensitizing strategy which may lead to substantial improvement in tumor control, with less normal tissue toxicity than conventional systemic administration of 5-fluorouracil, that would translate into improved cure rates and better survival. A noninvasive method is described for continuous in vivo monitoring of 5-fluorouracil production via magnetic resonance spectroscopy.

The present invention provides methods of treatment of patients suffering from the complications of blood sugar disorders: diabetic peripheral neuropathy and diabetic nephropathy by administration of IGF-1 via protein therapy or gene therapy. It relates to methods of treating an individual having a diabetic disorder or a hyperglycemic disorder, comprising administering to the individual an effective amount of a DNA vector expressing IGF-1Eb or IGF-1Ec in vivo or an effective amount of at the IGF-1Eb or IGF-1Ec protein in the early hyperalgesia stage or in patients that have advanced to the hyposensitivity stage. Treatment at the early hyperalgesia stage prevents subsequent hyposensitivity with increases or maintenance of sensory nerve function. IGF-1Eb or IGF-1Ec treatment also increases muscle mass and improves overall mobility, which indicates a treatment-related improvement in motor function. Treatment with IGF-1Eb or IGF-1Ec at the hyposensitivity stage reverses hyposensitivity and improves muscle mass and overall health.
