BACKGROUND: Interruption of sympathetic innervation to the liver and visceral adipose tissue (VAT) in animal models has been reported to reduce VAT lipolysis and hepatic secretion of very low density lipoprotein (VLDL) and concentrations of triglyceride-rich lipoprotein particles. Whether functional impairment of sympathetic nervous system (SNS) innervation to tissues of the abdominal cavity reduce circulating concentrations of triglyceride (TG) and VLDL particles (VLDL-P) was tested in men with spinal cord injury (SCI)...

Exosomes is a key component of cell paracrine secretion and can exert important effects in various disease models. However, the role of exosomes in neuron repair of spinal cord injury (SCI) has rarely been reported. In this study, Exosomes were isolated from cerebrospinal fluid of SCI and normal, and incubated neuron in vitro respectively to research its biological function in cell proliferation. The results demonstrated these exosomes all expressed CD9, CD63, CD81, Alix and Tsg101; however, only exosomes derived from cerebrospinal fluid of SCI could promote proliferation of neuron via ERK signaling pathway, and decrease cell apoptosis...

Patients with spinal cord injuries (SCIs) often have complex needs that require multidisciplinary support in specialist centres. Optimal management depends on seamless transitions between service providers. Delays at any point potentially compromise clinical outcomes and efficient resource utilisation. The Spinal Advisory Working Group aims to develop and implement practical initiatives to improve SCI care, initially focusing on admission and discharge. A literature review identified few relevant papers. In addition, the generalisability of the findings of these papers to SCI centres in the UK is unclear...

The appearance of meningeal carcinomatosis in breast cancer is an event that is being reported increasingly more frequently in the literature. It seems to be related with the lengthening of the patients' lives, improved sensitivity to diagnostic imaging and impermeability of the blood-brain barrier to the chemotherapeutic agents. It is an evolutionary form that affirms the metastatic invasion of the subarachnoidal space and is correlated with limited survival. Its diagnosis is difficult, due to the lack of specificity of the clinical signs dominated by headaches, cognitive disorders and possible signs and symptoms of progressive focal lesions...

Significant advancements in spinal epidural stimulation (ES) strategies to enable volitional motor control in persons with a complete spinal cord injury (SCI) have generated much excitement in the field of neurorehabilitation. Still, an obvious gap lies in the ability of ES to effectively generate a robust locomotor stepping response after a complete SCI in rodents, but not in humans. In order to reveal potential discrepancies between rodent and human studies that account for this void, in this review, we summarize the findings of studies that have utilized ES strategies to enable successful hindlimb stepping in spinal rats...

AIM: Lipids such as prostaglandins, leukotrienes and thromboxanes are released as a result of an inflammatory episode in pain (central and peripheral). METHODOLOGY & RESULTS: To measure these lipids as potential mechanistic biomarkers in neuropathic pain models, we developed a higher-throughput LC-MS/MS-based method with simultaneous detection of PGE2, PGD2, PGF2α, LTB4, TXB2 and 2-arachidonoyl glycerol in brain and spinal cord tissues. We also demonstrate that the LC-MS/MS method was more sensitive and specific in differentiating PGE2 levels in CNS tissues compared with ELISA...

Osteopontin (OPN), an extracellular matrix (ECM) glyco-phosphoprotein, plays an important role in autoimmune-mediated demyelinating diseases, including multiple sclerosis and experimental autoimmune encephalomyelitis (EAE). As an integrin and CD44 binding protein it participates in bidirectional communication between the ECM and target cells and affects transduction pathways that maintain neuronal and immune cells homeostasis. Its biological activity is also heavily influenced by microenvironment, which stimulates the cleavage of OPN and changes its functions...

Human locomotor patterns require precise adjustments to successfully navigate complex environments. Studies suggest that the central nervous system may control such adjustments through supraspinal signals modifying a basic locomotor pattern at the spinal level. To explore this proposed control mechanism in the leading and trailing limbs during obstructed walking, healthy young adults stepped over obstacles measuring 0.1 and 0.2 m in height. Unobstructed walking with no obstacle present was also performed as a baseline...

INTRODUCTION: Childhood angular kyphosis is rare, as most children are affected by a mixed kyphotic and scoliotic deformity. Published series involving a mix of kyphosis and kyphoscoliosis, pediatric and adult, congenital and acquired cases are almost exclusively authored by orthopedic surgeons, suggesting that (pediatric) neurosurgeons are not involved. CASE SERIES: We present five cases that illustrate the spectrum of angular kyphosis, and these were treated by a multidisciplinary team including child neurologist, orthopedic surgeon, and pediatric neurosurgeon as complementary partners...

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease affecting motor neurons of the brain and spinal cord, leading to progressive paralysis and death. Interestingly, many skin changes have been reported in ALS patients, but never as yet fully explained. These observations could be due to the common embryonic origin of the skin and neural tissue known as the ectodermal germ layer. Following the first observation in ALS patients' skin by Dr Charcot in the 19th century, in the absence of bedsores unlike other bedridden patients, other morphological and molecular changes have been observed...

Spinal cord injury (SCI) is damage to the spinal cord that leads to sudden loss of motor and autonomic function and sensory under the level of the injury. The pathophysiological advancement of SCI is divided into two categories: primary injury and secondary injury. Due to the loss of motor, sensory, or cognitive function, a patient's quality of life is likely reduced and places a great burden on society in order to supply health care costs. Therefore, it is important to develop suitable therapeutic strategies for SCI therapy...
