Heart Disease In the world today, there are many harmful and deadly diseases. These diseases are caused by people themselves or they are caused by human nature or probability. One of the many diseases that affect people is heart disease. Heart disease can strike anyone at anytime. The history of heart disease dates back to the Egyptian mummies. Pharaoh Merenptah died from atherosclerosis, which is a type of heart disease. Some early discoveries were made by Leonardo da Vinci and William Harvey…

The idea of taking stem cells and using them to create more stem cells is hardly new. With the experiments dating back to the 1950s, new breakthroughs are making it a viable option for these stem cells to be used to find cures for cancer, and help heal heart, brain, and spinal injuries that otherwise would have been debilitating or fatal. The controversial question that has arose from this research is whether or not it is ethical to kill an embryo to harvest these stem cells. The answer is no.…

Books have been banned ever since they have been written. Many people believe some books should be banned and some believe they shouldn't. A book that has been banned is My Sister's Keeper. This novel was banned for its explicit language but also for its violence and its medical viewpoints. Although My Sister's Keeper exemplifies family, love, and sacrifice. The novel My Sister’s Keeper, was banned in 2009 for a number of reasons. These include; offensive language, homosexuality, sexism,…

transcription, signaling pathways activated by cytokines, growth factors, and hormones, and intracellular signaling mechanisms. Researchers have also found out that the mechanisms of immune cell production, blood vessel constriction, heart rate, platelet activation, and immune cells production of cytokine are regulated by the neuroendocrine molecules and autonomous nervous system. These results…

blood or umbilical cordblood, is the leftover blood that is in the placenta and the section of the umbilical cord that remains attached to the placenta after the cord to the baby has been cut. This blood contains red blood cells, white blood cells, platelets and plasma, just like normal blood. But it also has lots of hematopoietic (blood-forming) stem cells that are similar to the ones found in bone marrow. This is why cord blood is now being used on an experimental basis as an alternative to…

done in by American Medical Association, about the vast majority of patients that have ischemic stroke are provided an antithrombotic medication on discharge (Bushnell et al., 2010, p. 1458). There are two classes of antithrombotic medication, anti-platelet and anticoagulant, both help to prevent the formation of thrombi, or clots, which if get caught in a brain blood vessel are what cause an ischemic stroke (“Antithrombotic Therapy”, 2016). More than 83% of ischemic stroke patients are…

Paracrine Signaling Signals that act locally between cells that are close together are called paracrine signals. Paracrine signals move by diffusion through the extracellular matrix. These types of signals usually elicit quick responses that last only a short amount of time. In order to keep the response localized, paracrine ligand molecules are normally quickly degraded by enzymes or removed by neighboring cells. Removing the signals will reestablish the concentration gradient for the signal,…

What is Lipitor? Lipitor is a brand name for drug atorvastatin, which is a newer selective and competitive inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme (HMG-CoA) reductase that belongs to a group of drugs known as statins. Atorvastatin was synthesized in 1985 and its development was mostly based on molecular comparisons of fungal metabolites and other synthetic inhibitors. Atorvastatin is approved for the reduction of elevated total cholesterol, LDL cholesterol, apo B and triglyceride…

Myocardial Infarction (MI) commonly known as heart attack occur when blood supply is interrupted, causing damage or death of the heart cells. What causes the heart muscle to lose its blood supply? Usually, the loss of the heart's blood supply is caused by the total blockage of a coronary artery by a blood clot on a cholesterol plaque in the artery. Cholesterol is a fatty chemical which is a part of the outer lining of cells in the body. Cholesterol plaque is the formation of a hard substance…

Strongyloides stercoralis is the nematode parasite (round worm) , found in north America , Montreal ,Chicago and the various area in the world.
