...Heart valve replacement is an open heart surgery procedure that people undergo when there is a dysfunction of one or more valves in the heart. These kind of procedure tend to be very risky and dangerous for patients’ lives, so physicians, medical teams and patients have to make decisions that would give the best outcomes to patients. According to an article from the J Saudi heart association, by Al Mosa and Al titled: “Mitral valve replacement for Mitral Stenosis,” retrieved from http://www.journalofthesaudiheart.com/article/S1016-7315(16)00009-9/pdf Mechanical mitral valve has a better rate of survival for patients age 65 and younger compare to tissue valve. Physicians should always individualized the choice of prosthesis type in patients with valvular heart disease. The...

...Security Analysis Edwards Lifesciences Jesse Blair Security Analysis Edwards Lifesciences Jesse Blair 2014 2014 Industry Analysis Medical Appliances and Equipment For this security analysis project I have chosen to research the medical equipment industry that specializes in artificial heart valves and related health products. This industry helps in the repair of cardiovascular diseases and critical care monitoring. There are two different types of artificial heart valves. There is the Tissue heart valve which is commonly given to older patients and it has a lifespan from 10 to 15 years. It is safer for older adults because it has less chance for post operation bleeding which could be fatal. The second type of heart valve is mechanical heart valve which has a lifespan of a patient’s lifetime. This type of valve has a higher risk of bleeding and requires for a patient to take blood thinner medication for the remainder of their life. Top Competitors When it comes to competitors there are three main groups that are leading the way in artificial heart valves and medical equipment. These companies are Edwards Lifesciences, Medtronic, and St. Jude Medical. You can examine the total revenues of the top three competitors on chart 1. Chart 1 Discussing the Competitors Medtronic Inc. Medtronic is the largest of the three competitors with revenues of over 17 billion last year. They are currently in the process of acquiring Covidien, which has been put on hold due...

...Jimmy Hernandez 11/24/2013 NT1110 Computer Structure and Logic Week 10 Research Project 3D Printing Today and Tomorrow I chose to do my research paper on 3D printing, were we are today and what the future looks like. While researching this project I learned that 3D printing has been around since the 80’s, and that it is also known as additive manufacturing. I chose this topic for a few reasons; first off this is a topic that has interested me fo a while now and I enjoy learning more about it. I believe this technology is going to have a huge impact on our future, like the computer, and the internet it will change the way we do things. I like that its impact is not limited to one area. I highlight in my project seven different areas that 3D printing is already being used and is reshaping those industries. One of these industries is architecture, construction, and engineering. Architects are using 3D printing to save time when putting together their scale models. In the future there will be no limitations to their designs; the reason for this being that construction companies are now experimenting with 3D printing to build parts of buildings. They have started to print using concrete and have been able to print up some wild angles and designs. These were difficult to pull off before because it was hard to make the form to pour the concrete. In the future architects and project managers will be able to work together and print sections of a building in one...

...Penicillin in 1928 (citizendium.org). Micrococcus luteus is considered a contaminant in sick patients and is resistant by slowing of major metabolic processes and induction of unique genes. It is a high G + C ratio bacterium. Micrococcus luteus is in the normal human bacterial flora which forms yellowish colonies and appears as a gram-positive coccus typically arranged in tetrads. Although compromised immune systems, the germ may become pathogenic in patients with impaired resistance, colonizing the surface of heart valves. In contrast to staphylococci (for which it may easily be mistaken) it is usually penicillin-sensitive. However, the most promising antibiotic proposed for Micrococcus luteus seems to be a combination of vancomycin, amikacin, and rifampicin. If the infection leads to severe blood flow problems to the organs and the tissues, however, valve replacement may become necessary similar to the situation in prosthetic valve endocarditis or inflammation of the inner heart lining. caused by more aggressive and highly resistant bacteria(Dürst, U N). The first thing we did in the group was go around to places and swab different areas or things of the school. I picked my beard to swab and inside of my cheek, but I picked the beard to do my project on because I thought it would be interesting to see if any growth was on my beard.When were finished with all of the swabs, we would then transfer the swabs to a plain nutrient agar, where would do our technique of swabbing lightly and...

It is a continuously expanding field, due to being a study that affects proliferation of cells and prolonging the life of a human organ (Vacanti, 2006). Tissue Engineering is not limited to medicine, but also includes several branches of sciences, such as molecular biology, bioengineering, nanotechnology; this is because of the different characteristics of different tissues. For example, recreating a pancreas means a tissue must be constructed to make insulin; this is a special function that is carried by the original organ (Johnson, 2010). Tissue engineering is seen as the answer to degenerating cells and...

...Stem cell A stem cell is essentially a “blank” cell, capable of becoming another more differentiated cell type in the body, such as a skin cell, a muscle cell, or a nerve cell. Microscopic in size, stem cells are big news in medical and science circles because they can be used to replace or even heal damaged tissues and cells in the body. They can serve as a built-in repair system for the human body, replenishing other cells as long as a person is still alive. Adult stem cells are a “natural” solution. They naturally exist in our bodies, and they provide a natural repair mechanism for many tissues of our bodies. They belong in the microenvironment of an adult body, while embryonic stem cells belong in the microenvironment of the early embryo, not in an adult body, where they tend to cause tumors and immune system reactions. Most importantly, adult stem cells have already been successfully used in human therapies for many years. As of this moment, no therapies in humans have ever been successfully carried out using embryonic stem cells. New therapies using adult type stem cells, on the other hand, are being developed all the time. Significance of the Study Stem cell therapy is a potential treatment for spinal cord injury and different stem cell types has been grafted into animal models and humans suffering from spinal trauma. Due to inconsistent results, it is still an important and clinically relevant question which stem cell type will prove to be therapeutically effective...

...Cri du Chat Cri du chat syndrome is a rare genetic disorder which approximately affects 1 in 20,000 to 50,000 live births. The disease does not depend on ethnic backgrounds, but is most common in the case of women. The disorder gets its name from the typical cry of babies born with this syndrome. The baby sounds like a kitten, because of problems with the nervous system and larynx. The good news is that about 1/3 of kids recover by the age of 2. Negative aspects of this disease may be: * Feeding problems, because they can't suck and swallow well * Low weight at birth and poor evolution * Motor, cognitive, and speech delays * Behavioral problems such as aggression, hyperactivity, and repetitive movements * Uncommon facial traits that can change in time * What is Cri-du-Chat syndrome? The name of this syndrome is French for "cry of the cat," referring to the distinctive cry of children with this disorder. The cry is caused by abnormal larynx development, one of the many symptoms associated with this disorder. It usually becomes less noticeable as the baby gets older, making it difficult for doctors to diagnose cri-du-chat after age two. Cri-du-chat is caused by a deletion (the length of which may vary) on the short arm of chromosome 5. Multiple genes are missing as a result of this deletion, and each may contribute to the symptoms of the disorder. One of the deleted genes known to be involved is TERT (telomerase reverse transcriptase). This gene is...

...vast numbers on waiting lists and how simply becoming a donor could save the life of another. Others may be apprehensive about making a decision about their bodies after death. In this paper we explain the origins and history of organ donation, the process by which organs are donated, the ethical implications behind organ donation and discuss many of the proposed solutions to solve the organ shortage issue. HISTORY OF ORGAN DONATION The origins of organ donation arose with several experimental transplants. The first successful transplant was a bone transplant in 1878, which used a bone from a cadaver. (14) Experimentally, bone marrow transplants began by giving patients bone marrow orally after meals to cure leukemia. This had no effect, but later when they used intravenous injections to treat aplastic anemia, there was some effect (14). One development that largely aided organ donation was the discovery of blood groups in the early 20th century. The first recorded kidney transplant was in 1909 and was a rabbit kidney inserted into a child suffering from kidney failure. The child died after two weeks (8). The first human to human kidney transplantation was in 1936 and failed. The first successful kidney transplant wasn't until 1954 and was between two identical twins. Soon after, heart transplants began,...

It was developed to help surgeons and medical health professionals overcome the human limitations of minimally-invasive surgery and enhance the abilities of the surgeons performing these procedures. It has many benefits to not only surgeons and medical facilities but for the patients as well. After years of development, training, and global awareness of the technology, medical manufacturers of the robots, surgeons, and medical professionals hope the technologies benefits will outweigh and overcome the environmental, financial, legal and ethical controversies. Dr. James McEwen, Dr. Brian Day and a team of engineering students, developed the very first surgical robot in 1983. It was used on March 12, 1984 for an orthopedic surgical procedure in Vancouver, Canada. Over sixty minimally invasive joint surgeries were performed in the first 12 months after the first successful surgery. After this, several other robotic devices were developed. A surgical scrub nurse was created...

...pathopharmacological features of a specific disease process, this paper will provide information related to heart disease in the form of coronary artery disease (CAD). A1. Pathophysiology Analysis Cardiovascular disease (CVD) is the number one cause of mortality worldwide and becoming a steadily more investigated problem due to its prevalence. Much research is going into genetic, inflammatory mechanisms and neuro-hormonal factors related to CVD as scientific knowledge evolves regarding complexity of this broad pathophysiology. Atherosclerosis is the leading cause of the subsection of CVD called CAD. This is a form of arteriosclerosis where there is progressive thickening and hardening of the vessel walls of the two major coronary arteries and their branches. The thickening is an accumulation of lipid-laden macrophages inside the wall of the artery leading to the formation of lesions and plaque buildup (McCance, K. & Huether, S., 2014). When the plaque develops on the coronary artery walls the pumping ability of the heart becomes impaired as oxygen and nutrients needed for heart function may be partially or completely impeded. Complete occlusion of a coronary artery or one of its branches leads to a myocardial infarction (MI) evidenced by impaired myocardial metabolism and ischemic tissue death. Depending upon the location or branch of the artery where occlusion takes place, different regions of the heart muscle are affected. This acute insult is a significant source...
