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 a disease in which antibodies directed at nicotinic acetylcholine receptors are produced, leading to a deficiency of acetylcholine receptors at the neuromuscular junction. This results in impairment of muscular excitation, which appears clinically as fatigable muscle weakness.Weakness of the extraocular muscles occurs in nearly 90% of all myasthenics at disease onset, with ptosis being the most common presenting feature.his results in impairment of muscular excitation, which appears clinically as fatigable muscle weakness.
