The flue piping of the system, whether for single or multiple appliances, should be as short a run as possible, and rise 1/4â³ per running foot up and toward the chimney. Whenever possible, do not exceed 10 feet of flue pipe length. Avoid using more than two 90-degree turns in the piping.
Myasthenia is treated with medications such as acetylcholinesterase inhibitors or immunosuppressants, and, in selected cases, thymectomy (surgical removal of the thymus gland). The disease is diagnosed in 3 to 30 people per million per year.yasthenia gravis (from Greek Î¼ÏÏ muscle, á¼ÏÎ¸Î­Î½ÎµÎ¹Î± weakness, and Latin: gravis serious; abbreviated MG) is a neuromuscular disease that leads to fluctuating muscle weakness and fatigue.
Myasthenia gravis is an autoimmune disorder, in which circulating antibodies cause weakness by blocking acetylcholine receptors at the post-synaptic neuromuscular junction, inhibiting the stimulative effect of the neurotransmitter acetylcholine.yasthenia gravis (MG) is distinguished from congenital myasthenic syndromes (which have similar symptoms) in that MG responds well to immunosuppressive interventions, while congenital myasthenic syndromes do not. Myasthenia gravis more commonly occurs in women under 40 years and men over 60.
