Assessing motor neuron disease.

چکیده
Hadjikoutis and Wiles draw attention to a number of circumstances in which the serum chloride and bicarbonate can be misleading. They do not mention that they will also be misleading if they are measured when hypercapnia is increasing or decreasing. An exacerbation of hypercapnia will take 4 – 6 days to raise the serum bicarbonate and lower the serum chloride to new steady levels. 1 How long it will take them to recover in a remission (or in a period of assisted respiration) is more unpredictable , since it is strongly influenced by the patient's chloride intake, which in turn depends mainly on the salt intake. 2 If the intake is low, the serum chloride may remain low, and the bicarbonate high, for a long time. A prognosis based on those levels would be unduly pessimistic. of chronic hypercapnia on electrolyte and acid-base equilibrium: I. Adaptation. of chronic hypercapnia on electrolyte and acid-base equilibrium: II. Recovery, with special reference to the influence of chloride intake.

Objective(s): Cell therapy has provided clinical applications to the treatment of motor neuron diseases. The current obstacle in stem cell therapy is to direct differentiation of stem cells into neurons in the neurodegenerative disorders. Biomaterial scaffolds can improve cell differentiation and are widely used in translational medicine and tissue engineering. The aim...
متن کاملDifferentiating lower motor neuron syndromes
Lower motor neuron (LMN) syndromes typically present with muscle wasting and weakness and may arise from pathology affecting the distal motor nerve up to the level of the anterior horn cell. A variety of hereditary causes are recognised, including spinal muscular atrophy, distal hereditary motor neuropathy and LMN variants of familial motor neuron disease. Recent genetic advances have resulted ...
متن کاملNeuromechanical Principles Underlying Movement Modularity and Their Implications for Rehabilitation
Neuromechanical principles define the properties and problems that shape neural solutions for movement. Although the theoretical and experimental evidence is debated, we present arguments for consistent structures in motor patterns, i.e., motor modules, that are neuromechanical solutions for movement particular to an individual and shaped by evolutionary, developmental, and learning processes. ...
متن کاملAssessing the Function of Motor Cortex: Single-Neuron Models of How Neural Response Is Modulated by Limb Biomechanics
Do neurons in primary motor cortex encode the generative details of motor behavior, such as individual muscle activities, or do they encode high-level movement attributes? Resolving this question has proven difficult, in large part because of the sizeable uncertainty inherent in estimating or measuring the joint torques and muscle forces that underlie movements made by biological limbs. We circ...
متن کاملSpinal Muscular Atrophy: A Short Review Article
Spinal muscular atrophy (SMA) is a genetic disorder which affect nervous system and is characterized with progressive distal motor neuron weakness. The survival motor neuron (SMN) protein level reduces in patients with SMA. Two different genes code survival motor neuron protein in human genome. Skeletal and intercostal muscles denervation lead to weakness, hypotony, hyporeflexia, respiratory fa...
