alpha-tocopherol (α-tocopherol) is in
Vitamin E intake and risk of amyotrophic lateral sclerosis Just a moment... and is the only known substance showing statistically significant preventative affect of Amyotrophic Lateral Sclerosis, per above paper. The authors discovered individuals who took Vitamin E supplements reduced their risk of developing Amyotrophic Lateral Sclerosis more than fifty percent AFTER about ten years. Several clinical studies tried detecting this effect but found no significant benefit in period (way too short to discover) . . . period was a couple of years. |

The arena of an axon
Researchers try piecing together intel until a complete picture of the syndrome's etiology is developed. The earliest clinical evidence is not necessarily the original event! But, in the case of Amyotrophic Lateral Sclerosis, the first apparent event by most authors' reports is the disconnect of an axon from a muscle fiber. This is unlikely the actual first event because such disconnects happen naturally (or by injury) and possibly by necessity. The Average Life Span of Skeletal Muscle Cells (seattlepi.com) https://tinyurl.com/MuscleFiberLifeSpan Thus a neuron's axon must find a way to connect a new muscle fiber (or reconnect an existing one). One of the amazing features occurring at the end of a neuron's axon is the build of a growth cone, which is a primary agent in the build of a synapse. Synapses are very small, estimated at around thirty nanometers: Size of synaptic cleft - Human Homo sapiens - BNID 108451 Once a neuron's axon's growth cone reaches a location where a synapse could be built, it will literally try building another one . . . these are some of the 'agents' who work on the problem: Growth cone - Wikipedia Filopodia - Wikipedia Lamellipodium - Wikipedia If successful, the muscle fiber will become responsive to stimulation and contribute to the force the muscle produces. |

Some time ago I commented cells move around inside by 'walking on stilts . . . ,'
filopodia and lamellipodia are reflective of the stilt like structures facilitating the moment of new cells possibly into the space prior cells failed. This paper reviews the processes in great detail . . . : The Growth Cone Cytoskeleton in Axon Outgrowth and Guidance The growth cone cytoskeleton in axon outgrowth and guidance - PubMed I would not be surprised many non-biologists would find this paper (and some of the others) more difficult to follow. A key point however, is why are the DiPALS results of 31 moons not seen as very different from the RespiStimALS result of 56 moons? A twenty-five moon difference ought not be overlooked. One big difference between the RespiStimALS study and the DiPALS study is the DiPALS study is the only one not 'blinded,' rather the study was open . . . exposed. The primary point of double blind placebo controlled studies is the prevention of tampering . . . no one can tamper with such studies because no one knows who is getting what. Such was not true in the DiPALS study. |

re: ". . . anything and exciting out there in the field artificial respiration? . . ."
Well, ECMO (Extracorporeal membrane oxygenation - Wikipedia) is new but its use is unprecedented in Amyotrophic Lateral Sclerosis and the iron lung is old but I do not believe its use was ever contemplated in this context, its consideration would be new: indeed there may only be one individual left on an iron lung. re: the pacer, the main new observation is the large inclusion of 'ineligible' patients in the DiPALS and RespiStimALS studies, which report I continue working on. My outline is nearly perfected. |
