Duchenne muscular dystrophy is an inherited disease that is also known as muscle weakness that gets worst after a short period of time. Duchenne muscular dystrophy is caused by defected gene for dystrophy which is a protein in the muscle that is often said to be passed down from generation from family members. Duchenne muscular dystrophy is more common in people without any family history. Duchenne muscular dystrophy is known to only effect guys. Due to the way this gene in inherited‚ girls are not

The Action of Naturally Occurring Toxins and Medicines It is important to classify toxins and medicines (drugs) in order to understanding the mechanism and function of each one of them. By doing so‚ it is also possible to increase their values by altering their mechanism (e.g. converting toxins to drugs) to cure diseases and improve human health. Therefore in this review‚ the mode of action of several toxins and drugs as well as their effects on human body will be discussed. 1. Cobratoxin Cobratoxin

placement of the catheter‚ begin selecting the NAVA level‚ or the sensitivity of the catheter that is needed to pick up the electrical activity. Neuromuscular signal strength will greatly alter the level needed to support the patient. For example‚ stronger neuromuscular signals will need a decreased NAVA level to provide ventilation‚ while weak neuromuscular signals will require a higher NAVA level. A calculation can be done to estimate the level of PEEP needed. The calculation is NAVA Level= PIP-PEEP
