Objectives: Spinal cord ischemia (SCI) is one of the major concerns of postoperative paraplegia during major vascular or aortic surgery. Since mitochondrial dysfunction develops at the early stage of SCI, this study tested the neuronal protective effect of transplantation of viable mitochondria to the ischemic cord in rats.

Methods: SCI was induced by crossclamping of thoracic aorta at T6 level for 25 minutes, followed by release of vascular clip to restore aortic blood flow in the anesthetized rats. Read More

Cardiovascular (CV) issues after spinal cord injury (SCI) are of paramount importance considering they are the leading cause of death in this population. Disruption of autonomic pathways leads to a highly unstable CV system, with impaired blood pressure (BP) and heart rate regulation. In addition to low resting BP, on a daily basis the majority of those with SCI suffer from transient episodes of aberrantly low and high BP (termed orthostatic hypotension and autonomic dysreflexia, respectively).

There is continuing controversy relating to the primary afferent neurotransmitter that conveys itch signals to the spinal cord. Here, we investigated the DRG and spinal cord expression of the putative primary afferent-derived "itch" neurotransmitter, gastrin-releasing peptide (GRP). Using ISH, qPCR, and immunohistochemistry, we conclude that GRP is expressed abundantly in spinal cord, but not in DRG neurons. Read More

The enthusiasm for producing patient-specific human embryonic stem cells using somatic nuclear transfer has somewhat abated in recent years because of ethical, technical, and political concerns. However, the interest in generating induced pluripotent stem cells (iPSCs), in which pluripotency can be obtained by transcription factor transduction of various somatic cells, has rapidly increased. Human iPSCs are anticipated to open enormous opportunities in the biomedical sciences in terms of cell therapies for regenerative medicine and stem cell modeling of human disease. Read More

Neuropathic pain, pain arising as a direct consequence of a lesion or disease affecting the somatosensory system, is relatively common, occurring in about 1% of the population. Studies in animal models describe a number of peripheral and central pathophysiological processes after nerve injury that would be the basis of underlying neuropathic pain mechanism. Additionally, neuro-imaging (positron emission tomography and functional magnetic resonance imaging) provides insights in brain mechanisms corresponding with mechanistic processes including allodynia, hyperalgesia, altered sensation, and spontaneous pain.

Part 2 of this review concerns the application of melatonin (Mt) to the treatment of aged patients with cardiovascular diseases and other pathology with reference to its genoprotective and anticarcinogenic action. Effects of Mt on the cardiovascular system are underlain by its antioxidative, vasodilating, and sedative activities, the ability to regulate the heart rate and inhibit platelet aggregation. Certain authors report negative correlation between Mt production and blood cholesterol level. Read More

Individuals with spinal cord injury (SCI) are susceptible to an array of secondary health complications. Some of these health concerns are attributable to the SCI per se, but many are secondary to the resulting immobility. For example, the incidence of pressure ulcers, type 2 diabetes, and cardiovascular disease are greatly increased in this population. Read More

Chronic spinal cord injury (SCI) is associated with the development of serious medical concerns. In fact, it is increasingly well documented that most SCI patients who survive the first 24 hr will rapidly develop, within a few months to a few years, cardiovascular problems, type II diabetes, muscle wasting, osteoporosis, immune deficiencies, and other life-threatening problems. The cellular mechanisms underlying these so-called secondary health complications remain unclear, and no drug or standard approach has been developed to specifically treat these complications.

The consequences of spinal cord injury on the function of sympathetic pathways in the periphery have generally been ignored. We discuss two types of plasticity that follow disruption of sympathetic pathways in rats . The first relates to the partial denervation of sympathetic ganglia that would follow the loss of some preganglionic neurones. Read More

We utilize spinal cord protection including cerebrospinal fluid drainage (CSFD), adjuncts of aortic distal perfusion, reconstruction of the intercostal or lumbar arteries and deep hypothermia in TAAA repair. This report describes the results of surgical treatment for TAAA including postoperative neurological outcome. Read More

Int J Radiat Oncol Biol Phys 2004 Mar;58(4):1268-79

Division of Radiation Oncology, The University of Texas M. D. Anderson Cancer Center, Houston, TX 77030, USA.

Purpose: To investigate the possibility of using intensity-modulated radiotherapy (IMRT) to reduce the irradiated volumes of the normal lung and other critical structures in the treatment of non-small-cell lung cancer (NSCLC) and to investigate the effect of IMRT on the potential of spreading low doses to large volumes of normal tissues in such treatment.

Methods And Materials: A retrospective treatment planning study was performed to compare IMRT and conventional three-dimensional conformal radiation therapy (3D-CRT) for 10 NSCLC patients (Stage I-IIIB). In the IMRT plans, three to nine coplanar beams were designed to treat 95% of the planning target volume with 63 Gy and to minimize the volumes of the normal lung, esophagus, heart, and spinal cord irradiated above their tolerance doses.
