Q: 

I understand stem cells will create a new heart if placed near heart cells in their growth. and will shapeshift into anything thats needed, in a similar situation. Are these cells that would be discarded? or are these cells of a baby that won''t get born?

A: There are several different sources for stem cells. Embryonic stem cells can be taken from an aborted embryo. However, the cells would normally be discarded after an abortion so it''s better to use the cells for research that can help others than just to throw them away....
Q: 

Why people do not suffer from heart cancer?

A: Cancer is most common in cells that are rapidly dividing to produce new cells. Consequently, most cancers occur in epithelial cells (carcinomas) and blood cells (leukemias and lymphomas). Epithelial cells line the lungs, intestines, breast, prostate, ovaries, bladder and uterus. These are the organs where most cancers occur. heart cells (like skeletal muscle cells) have stopped dividing (they are called ''post-mitotic cells'' - mitosis is the process of cell division). Because they are not dividing they are at very low risk for developing cancer. For the same reason,...


Q: 

Cancer of the heart? Why is that one of the few organs of the human body?

A: Strictly speaking it''s not an organ, it''s a muscle. Possibly it is less subject to cancer because it it doesn''t process anything, and doesn''t have any intimate, direct contact with carcinogens. It just pumps. you can get tumours of the heart You are right ...its because its a muscle, which is a tissue rarely affected by cancer. http://www.newton.dep.anl.gov/askasci/mole00/mole00484.htm heart cancer is extremely rare yet there such thing as heart cancer. Cancerous (malignant) tumors of the heart are most often sarcomas. Occasionally, cancer can spread to the heart, such as from lymphomas that originate in the structures of the chest near the

Q: 

Why do you not get cancer of the heart.......?

A: i heard a researcher saying that cancer is not a disease, dont chuck this out. read it fully. anyways what happens is that once there is a trauma to a region of the body the body requests the repair of that part. but cancer happens when the brain doesnt send out the signal to stop once when fully repaired. as you can see lung cancer is higher among smokers as smoke damages the lungs.. so a repair intiative happens that fails.. similarly ulcers, in mouth stomach.. and everyother region. where as the heart unlike the head is very much protected by the ribs and its pretty safe from most trauma other than extended use and fat buildup... so there is no need to repair what aint damaged. so thats the reason that cancer doesnt occour in heart....


Q: 

Does green tea prevent heart attack?

A: yes, it truly does. :) the only negative side effect reported from drinking Green Tea is insomnia due to the fact that it contains caffeine. However, Green Tea contains less caffeine than coffee: there are approximately thirty to sixty mg. of caffeine in six - eight ounces of tea, compared to over one-hundred mg. in eight ounces of coffee. advantages are : - Act as antioxidants - Prolong life - Prevent and treat cancers - Help recovery from heart attacks and strokes - Keep arteries healthy - Reduce high blood pressure - Prevent and treat diabetes - Burn fat. Exercise Longer - Protect the lung from smoking - Protect the liver from alcohol - Boost immunity. Fight off flu and cold - Sooth stress and calm the mind - Prevent tooth decay and cure bad breath - Build...


Q: 

About the heart?

A: No concise answer available; the heart muscle once damaged, scars. However we now have evidence that it isn''t that it "doesn''t heal" it heals too slow to help us ---new findings show that help will come in the form of stem cells that rebuild the muscle!Here is the article;-DrRich The news media has been reporting all week that scientists now have evidence that damaged heart muscle can repair itself. This is true, but any clinical benefit that might derive from this new knowledge is a long way off. As reported by investigators from the New York Medical College in the January 3, 2002 issue of the New England Journal of Medicine, after a heart transplant,

Q: 

Does the deficiency of iron cause palpitations in heart?

A: Yes, it is also recognised as Heamic Murmur of the heart. Due to lack of oxygen the heart itself is deprived of oxygen and at the same time it has to provide blood to all the organs of the body hence there is palpitation, common amongst females. Hence removal of cause is equally important e.g bleeding piles, instead of giving Fe pills. In extreme condition patients may require packed cells transfusion. anemia can cause heart murmurs. the blood is less viscous and the heart is pumping more to try to get oxygen to the body, this increases turbulence and causes a murmur. I''ve never heard of iron deficiency causing palpitations. If you are deficient in iron, you could...


Q: 

heart Palptations

A: Dear Debra, The heart"s electrical system is such that any cell anywhere in the heart can spontaneously discharge the electrical voltage present between inside and outside of the cell when the heart is at rest.  This voltage discharge is conducted to all the other cells in the heart and makes the whole heart contract, producing a premature heart beat.  If the premature beat comes very soon after the preceding normal beat, it won"t pump enough blood to be felt by the body in which the heart resides, which interprets it as a skipped beat.  Then there"s a long pause while the
Q: 

heart Attack ?

A: Acute myocardial infarction (AMI or MI), commonly known as a heart attack, is a disease state that occurs when the blood supply to a part of the heart is interrupted. The resulting ischemia or oxygen shortage causes damage and potential death of heart tissue. It is a medical emergency, and the leading cause of death for both men and women all over the world.[1] Important risk factors are a previous history of vascular disease such as atherosclerotic coronary heart disease and/or angina, a previous heart attack or stroke, any previous episodes of abnormal heart rhythms or syncope, older age- especially men over 40 and women over 50, smoking,...
