BACKGROUND
With increasing awareness of motor neuron disease (MND) in Australia, the approach to respiratory management of patients with this disease will more commonly face the respiratory physician.
OBJECTIVE
The aim of this study was to determine if standard respiratory function tests could
Amyotrophic lateral sclerosis (ALS) most likely results from a multifactorial gene-environment interaction. Strenuous physical activity and occupational exposures have been suggested to play a role, and an abnormal response to hypoxia has been proposed in ALS pathogenesis. To test the hypothesis of
The clinical course of the degenerative motor neuron disorder amyotrophic lateral sclerosis (ALS) is closely related to hypoxia. The normal response to hypoxia involves two pathways in particular: the hypoxia inducible factor 1α (HIF-1α) pathway (which notably controls the synthesis of vascular
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder of upper and lower motorneurons, leading to death in 3 to 5 years. Respiratory insufficiency and hypoxemia are closely linked during the clinical course of ALS. Chronic respiratory insufficiency and hypoxemia generally occur late in
The central nervous system (CNS) uses a significant amount of oxygen for energy production. Decreased oxygen supply due to impaired blood supply critically damages the CNS. As chronic hypoxic conditions have diverse effects via the excessive production of reactive oxygen species, protection from
Amyotrophic lateral sclerosis is a fatal neurodegenerative disease that affects motor neurons. The recruitment of autophagy (macroautophagy) and mitochondrial dysfunction are documented in amyotrophic lateral sclerosis patients and experimental models expressing mutant forms of Cu, Zn superoxide
We investigated the mechanisms underlying abnormal vascular endothelial growth factor (VEGF) production in amyotrophic lateral sclerosis (ALS). We immunohistochemically studied VEGF, its receptors VEGFR1 and 2, and hypoxia-inducible factor-1α (HIF-1α) in autopsied ALS spinal cords. We also
BACKGROUND
Amyotrophic lateral sclerosis (ALS) is a devastating motor neuron disease causing paralysis and death from respiratory failure. Strategies to preserve and/or restore respiratory function are critical for successful treatment. Although breathing capacity is maintained until late in disease
Motor neuron disease (MND), or amyotrophic lateral sclerosis, is a fatal neurodegenerative disorder characterized by a progressive loss of motor neurons in the spinal cord and the brain. Several angiogenic and neurogenic growth factors, such as the vascular endothelial growth factor (VEGF),
A 66-year-old man with dyspnea on exertion suffered a cardiac arrest and was referred to our hospital after emergency room intubation. Chest X-ray films detected no abnormalities. Blood gas analysis showed hypoxemia with normal A-aDO 2, and pulmonary function tests revealed combined ventilatory
Angiogenin (ANG) gene, coding for an angiogenic factor up-regulated by hypoxia and expressed in ventral horn motor neurons, is a novel candidate for the pathogenesis of amyotrophic lateral sclerosis (ALS). ALS is a fatal neurodegenerative disease characterized by the selective loss of cortical and
Animal studies have highlighted the potentially neuroprotective role of vascular endothelial growth factor (VEGF). Low levels of this growth factor have been found in the cerebrospinal fluid (CSF) of patients with amyotrophic lateral sclerosis (ALS). VEGF (and other proteins, such as erythropoietin
Genetic variations in two hypoxia-inducible angiogenic genes, VEGF and ANG, have been linked with sporadic amyotrophic lateral sclerosis (SALS). Common variations in these genes may reduce the levels or functioning of their products. VEGF and ANG belong to a larger group of angiogenic genes that are
Previous studies have demonstrated that domiciliary ventilatory support improves survival, quality of life and cognitive function in motor neuron disease (MND). These benefits are partly attributed to better sleep quality and less hypoxia. In a retrospective analysis we compared the effect of
Neuromuscular biopsy is still an essential method for diagnosing vasculitic neuropathy, although its diagnostic sensitivity is at most 60%. Our objective was to examine the expression of hypoxia-inducible factor 1alpha (HIF-1alpha) in peripheral nerves and to evaluate its usefulness in diagnosing
