	Hildt: Ethics of Neural Tissue Transplantation (Site not responding. Last check: 2007-10-21)
		Neural tissue transplantation gives rise to ethical issues in two different areas that need careful examination: the first, ethical problems linked to the use of tissue from aborted human fetuses; and the second, ethical issues concerning the graft recipients in clinical trials, i.e., his or her well-being, personality, and personal identity.
		In contrast to this, neural tissue transplantation is an operative procedure with irreversible consequences.

	Neural Tissue (Site not responding. Last check: 2007-10-21)
		Neural Tissue is specialized for the conduction of electrical impulses that convey information or instructions from one region of the body to another.
		About 98% of neural tissue is concentrated in the brain and spinal cord, the control centers for the nervous system.
		They provide the physical support for neural tissue, as well as maintaining the chemical composition of the tissue fluids and defending the tissue from infection.

	FETAL TISSUE
		As evidenced in animal trials, the transplantation of fetal neural tissue from the brain, spinal cord and peripheral nervous system may be the key to effective therapeutic treatment of an array of neurologic disorders.
		With the use of adult tissue and organs in a transplantation, it is very often the case that the tissue dies or is rejected by the host as being a foreign tissue.
		I agree that fetal tissue is different from a kidney or a liver, or any other type of organ or tissue, because the provider of fetal tissue has the potential for providing an almost unlimited supply of fetal tissue as long as she is within child-bearing age.

	Project 1
		An aim of using NTPT in assessment is to change the length of the neural tracts using body segments as levers, thus applying tension on the neural structures gaining an impression of their mobility and sensitivity to mechanical stresses (Shacklock, 1995).
		The neural tissue slack is taken up when the NTPT is initiated, to be followed by neural tissue mobilisation in their tracts.
		SLR creates tension and movement to the neural tissue by increasing the distance between the extremities of the neural tissue tract, causing caudad movements of the lumbosacral roots in relation to the intervertebral foramen (Goddard and Reid, 1965).

	Foetal Cell Transplantation (Site not responding. Last check: 2007-10-21)
		In Europe, experimental neural tissue transplantation programmes are currently in an equivalent of phase I or II of drug trials, and are accepting only a very limited number of patients.
		Neural tissue grafting can be a highly effective, and constitutes a potentially curative approach for progressive neurodegenerative disorder such as PD. Virtually all signs and symptoms of PD have been shown to be positively affected by grafting, but not necessarily in one patient simultaneously.
		There remain several technical aspects were improvements are needed before a wide spread of neural tissue implants can be recommended as a treatment for PD. These include better definition of the donor tissue in terms of infectious risks, the need and duration of immunosuppressive treatment, and the minimal amount of tissue needed for certain effects.

	Safe and Effective Stimulation of Neural Tissue: National Institute of Neurological Disorders and Stroke (NINDS)
		In order to minimize tissue damage, more information is needed on methods of preventing damage, the safety of new biomaterials, as well as better methods of physically stabilizing microelectrodes in neural tissue.
		Determine the relationships between tissue damage at various microelectrode depths and in various cerebral cortical regions, and the stimulus variables of pulse frequency, charge density, charge per phase, and current density (based on geometric, and if possible, on real exposed microelectrode area) using current regulated, chronic stimulation.
		Examine possible mechanisms of tissue damage including mechanical trauma, mass activation of cortical neurons and changes in the composition of key constituents of the extracellular fluid surrounding the neurons including glucose using stimulation levels at or below those known to cause histopathological damage using the above described microelectrodes.

	Grant Abstract (Site not responding. Last check: 2007-10-21)
		In neural tissue transplants for Parkinson�s disease patients, new neural tissue from the fetal substantia nigra is placed into the striatum.
		In the first method, the new tissue will then be bridged to the striatum with additional fetal neural tissue co-grafts placed along a direct route between the substantia nigra and the striatum.
		The advantage of the polymer over the neural tissue co-grafts is that the polymer is bio-absorbable, meaning that while the neural fibers are reaching their destination, the polymer is being reabsorbed, eventually leaving only a pure neurocircuit between the substanti nigra and striatum.

	Fetal Tissue Transplantation Research
		Fetal tissue is not fully differentiated and will adapt fairly well to the signals received from surrounding tissue in a host, growing and differentiating to function as part of the host organ.
		Two stipulations from federal regulations covering fetal tissue research also apply to research using fetal tissue: the researcher may not be involved in the timing, method, and procedures used to terminate the pregnancy; and no inducements, monetary or otherwise, may be offered to the mother to terminate pregnancy for purposes of performing research.
		Their primary argument against the use of fetal tissue is that it may encourage women to become pregnant for the sole purpose of aborting their children for their tissues and they forecast an increase in abortions to meet the demand for fetal parts.

	Neural Induction
		According to this model, the anteroposterior character of the neural ectoderm is dependent upon corresponding differences in the underlying dorsal mesoderm.
		Recall that noggin transcripts are synthesized in the organizer at the gastrula stage and in the notochord at later stages; both of these tissues have been implicated in neural induction.
