Myelin is a lipoprotein sheath which is wrapped around nerve axons, thereby insulating them. Myelin is composed of approximately 70% lipid and 30% protein (in comparison to 50 to 30% lipid concentration in normal cells) and is produced by the oligodendrocytes in the central nervous system (CNS) and Schwann cells in the peripheral nervous system (PNS) (Jackman et al., 2009; Rolak, 2002). Myelin serves many purposes as its low capacitance and high resistance nature helps it play the role of an insulator

Picture something for me, you are walking to school on a nice sunny day, you stop to cross the street, a car drives by shoots you up and leaves you on the ground to ooze the remaining life from the new bullet holes now decorating your body. When a person thinks of a gang they think of a group of thugs with weapons and bad intentions, they do not picture poor children scared for their lives. Children in poor areas have grown up in gang violence, a child’s upbringing creates them into the person

Heart disease is defined by the decreasing of blood flow to coronary arteries that supply blood to the cardiac muscles. The lumen of blood vessels become increasingly narrower, due to a build of plaque through a process called atherosclerosis. The resulting tissue necrosis eventually leads to heart attacks, cardiac arrests, and heart failure. Moments after the patient will stop breathing and become unresponsive. Emergency maneuvers to maintain perfusion in these cardiac emergencies are key to favorable

and women suffering from a heart attack caused by CAD. Coronary Artery Disease is a disease in which plaque builds up inside the arteries. The buildup of plaque in the arteries causes a narrowing of the arteries. This results in the inability of the blood containing necessary oxygen to be transported to the heart and thus, to the rest of the body. The arteries are supposed to normally supply oxygen to the heart

1. The nurse completes the medication reconciliation for this patient. Explain the information gained in this procedure and the purpose of the medication reconciliation. (5 points) The medication reconciliation presented a panoramic view of the dose, route and frequency of the prescription the patient is currently taking. After it is performed it can be observed that the patient is taking 1200mg of Ibuprofen which is the max dose per day. Tylenol is prescribed 500mg every 6 hours PRN, patient need

cardiomyopathy, and coronary heart disease. In heart failure, the increase in the resistance against which the heart pumps (afterload) further depresses cardiac output. A reduced renal blood flow induces renin secretion and increased plasma aldosterone and angiotensin concentrations. Water and sodium retention increases blood volume causing central venous pressure to increase. These changes overall first help to maintain cardiac output however in the long term they eventually cause morbidity and mortality

Acute myeloid leukemia, also known as AML is a cancer that affects both blood and bone marrow and progresses quite rapidly. AML is caused by damage to the DNA of the developing cells inside of bone marrow; then these immature cells develop into leukemic white blood cells, called myeloblasts. It is not certain as to what causes the damage to the cells but there are certain risk factors such as old age, smoking and even previous cancer treatment/chemotherapy. Symptoms to watch out for include: easy

12.30.2017 ClotX is an autoinjector-based agent composed of supplemental coagulation factors, also known as clotting factors, that work in tandem to control hemostasis. Coagulation factors are human blood plasma glycoproteins that enable the body’s coagulation response pathways, also known as blood clot formation. While the body’s bloodstream naturally contains its own supply of clotting factors, ClotX provides a supplemental supply that is able to bolster and accelerate the natural hemostasis process

risk cases often requires surgery to repair or replace heart valves in patients with severely damaged valves. Most patients who have RHD have the condition called mitral stenosis. Mitral stenosis restricts the blood flow from the left atrium to the left ventricle. Generally, this means less blood that goes through, the more severe the problem becomes. The symptoms for this typically can occur 10-20 years after the first occurrence of rheumatic fever as a child.The most common surgery for RHD is balloon
