How Can Stem Cells Be Used to Treat Congestive Heart

How Can Stem Cells Be Used to Treat Congestive Heart Failure?

Heart failure is a devastating blow to the body system, and despite the best efforts of clinicians and researchers often results in permanent organ damage and eventual death. Researchers are fighting to put a stop to the high mortality rate of congestive heart failure, and believe stem cells may be the way to do it.

The possible uses for stem cells have made it a highly published topic in medical journals today. Stem cells are the precursors to every cell in the body, and are primarily produced in the bone marrow in adults. During times of crisis, such as when a patient suffers from leukemia, the spleen and other organs that possessed stem cells during fetal development will take over production. This is the body’s way of maintaining proper cell balances and replenishing itself as old cells die. For example, red blood cells in the circulation only have a lifespan of approximately four months; during that time the hematopoietic stem cells in the bone marrow are continuously producing new rubriblasts, the precursor cells that will over time become mature erythrocytes.

There are several forms of stem cells; for the sake of research scientists are currently focusing on the embryonic and adult varieties. Embryonic stem cells come from a blastocyst, a four to five day old human embryo. During gestation these pluripotent cells will divide and multiply, forming the body and internal organs of the fetus. Embryonic stem cells are highly valued for research for several reasons; they are able to provide large numbers of replenishing cells and have no limitations on what form of cells they can become. The use of embryonic stem cells is highly controversial, however, due to the fact that collection often requires the destruction of the embryo.

There are several methods that have been published in research journals regarding the application of stem cells in the treatment of congestive heart failure. Congestive heart failure results when cells in the heart are dysfunctional or destroyed and the heart is unable to properly pump blood throughout the body. Some patients are able to be treated using mechanical aids or transplant, but this is not always the case. Several years ago a group of patients with no other available options for treatment agreed to be part of a test study regarding stem cells. Autologous stem cells were removed from the marrow and injected into the failing heart tissue through the chest wall. Patients who received this treatment showed marked improvement, presumably as a result of stem cell action. The precise means by which this occurs is still unknown; however, research scientists speculate that the stem cell is either growing new vessels or acting as a beacon to bring other cells in to repair the damaged tissue.

Another possibility regarding stem cells is the growth of tissue for transplant. Hearts available for an organ transplant are not as easily obtained as physicians would desire, and there are often waiting lists years long for every available organ. Stem cells grow readily in a laboratory environment, and if unstimulated to differentiate will reproduce pluripotent daughter cells. This results in a tissue that will essentially adapt to whatever environment it is placed in. Research scientists speculate that with the proper environment essentially grow heart tissue and transplant it to the patient who has suffered heart failure, replacing the dead and damaged tissues with live, vital tissue. This procedure would allow the heart to function more easily and hopefully give the patient a better chance for survival.

With current treatment the prognosis for sufferers of congestive heart failure is grim. At least fifty percent will die within five years of being diagnosed, and those who are not victims of this mortality rate will feel the effects of their heart failure for the rest of their lives. Stem cell research represents a chance for those patients to beat these odds.

Help With Quitting Smoking

Enhancing the quality and length of your life by quitting smoking is a worthwhile effort. It is definitely not an easy task, but it can be accomplished with time and patience. To quit smoking successfully, finding out what your options are. Knowing where to go for help is a wise first step. Quitting smoking is the best move that you can make for your health and the health of all of those around you. Just about everyone knows by now that smoking causes diseases that shorten your life or those that may even end it. Diseases such as lung cancer, throat, esophagus, bladder, and kidney, and pancreas cancers are some horrible things caused by smoking for a start. Not to mention some leukemia, stomach, and cervix cancers, and newly added by the Surgeon General is pneumonia. People who smoke are more than three times as likely to die due to heart attack as non smokers. Smoking is a major risk factor for a disease that narrow the blood vessels that transport blood to the limbs and muscles called peripheral vascular disease as well as the disease that causes some strokes.

If thats not enough to convince you to stop smoking, lets look at your appearance. Premature wrinkling of skin, chronic bad breath, discolored fingernails and hair, and an increase risk of macular degeneration a leading cause of blindness in the elderly. Smoking over the age of thirty-five if you are a woman can put you in a high risk group for stroke, heart attack, and blood clots of the legs, low birth weight of babies and miscarriages. But the hopeful portion of this message is that if you decide to quite regardless of how long youve smoked or how much, quitting will help you to live longer. In as little as twenty minutes after quitting smoking the heart rate and blood pressure drops and in one to nine months following quitting smoking, circulation in your hands extremities and lung function increases. Shortness of breath decreases and your lungs begin to function properly, cleaning the lungs and removing mucus that causes infection. Fifteen years of non smoking and your risk of heart disease is that of non smoking persons. These benefits can be obtained from quitting smoking even if you are suffering from a smoking related illness already. Smoking is less socially accepted now more than ever. Smoking bans have been placed in just about every workplace in the nation along with airports, public buildings. Even friends may insist that you not smoke in their houses or cars. Some people may even find dating more difficult because of a bad smoking habit. So the social impacts of not smoking will probably change your life for the better if you quit.

If you have a family, that is another great motivation to quit smoking. The main reason is that the secondhand smoke could pose serious health problems for others who do not deserve such things. You should also consider what kind of role model you are being to any small children that you live with, whether they are your own kids, siblings, nieces and nephews, or any other relation. You may be living with kids who look up to you as an authority figure, and if you teach them that smoking is alright you will feel very guilty later in life.

Some of the many new products used to help an individual to stop smoking are really very effective. Counseling services, reading materials, medicines, and patches are all widely available and have produced some amazing results. Educational materials alone may be the best beginning start to an attempt to quit because once you know what kind of damage you are doing to your body the prudent and reasonable person will definitely see that it is the very best thing to do. However, it has been documented and researched that the highest success rates occur when a combination of methods are used simultaneously. Take the time and do it for yourself and your loved ones, quit for life.

The Essence of PET Scans in Determining and Healing Lymphoma

The Essence of PET Scans in Determining and Healing Lymphoma

This interesting article addresses some of the key issues regarding Lymphoma. A careful reading of this material could make a big difference in how you think about Lymphoma.

The malignant cells that cause lymphoma begin at the lymph nodes. Tumor develops when there is an enlargement of the node. The case is quite similar to lymphoid leukemia, but this only involves the bone marrow where the blood cells are produced through the haematopoesis process as well as the circulating ruddy.

The first description of this dreaded disease was first published in 1832. This was done by Thomas Hodgkin, thus the name of the Hodgkin type of this illness. There are many other forms that have been discovered since then and all these are now part of a large lot of illnesses that are known as hematological neoplasms.

When you start feeling that you have the symptoms, especially the enlarged lymph nodes, you should look into the help of your doctor. This event may not always mean that you are sick, but to compose affirmative that you are okay, you have to get yourself checked by a professional. The first move that doctors may require you to undergo is biopsy, the type of which will be dictated as to the organs that are infected with the disease. After it was established that you already have it, the doctors will then try to categorize from which emotions of this illness you are suffering from. Before you can be given proper treatment for your condition, your bone marrow needs to represent precise and you posses to pep through various tests and scans.

PET Scans

One of the special kinds of scans that you may be asked to undergo is PET scan or Positron Emission Tomography. This is able to impel the cancers based on the high activity that is happening on the cancer cell.

Other types of scans provide disparate results. For example, MR type and CT scans present good quality photographs of the various body parts where you answerability view the masses of tumors and swollen nodes. The problem with these scans is the fact that doctors cannot based their findings whether a person has the illness based on the size and shape of what was photographed through these processes. This is what PET scans are able to fill in the blanks.

PET scans are useful in the procedure because these are used to map out the disease on a person’s body. Along with the other kinds of tests, all results can be used to determine the stages of the disease. This is also able to find out if the lump that showed up on other tests, is cancerous or not. After the aspect was settled, the doctor can then emanate to give the necessary treatment, whether you need to go through chemotherapy or it will be best to undergo radiation.

After some cycles of chemotherapy, you have to go through the same scans and it will help to assess how bushy-tailed your body is responding to it. When the treatment has been done, you reposing have to go wrapped up PET scans to know whether the lump still has cancer cells, scar tissue or it has commenced been healed.
There’s a lot to understand about Lymphoma. We were able to provide you with some of the facts above, but there is still plenty more to write about in subsequent articles.
