Stem cell therapy




In living organisms, an undifferentiated cell that can produce other cells that eventually make up specialized tissues and organs. There are two major types of stem cells, embryonic and adult. Embryonic stem cells are located in the inner mass of a blastocyst (an embryo at a very early stage of development), and they eventually give rise to every cell type of the adult organism. Adult stem cells are found in some tissues in the adult body, such as the epidermis of the skin, the lining of the small intestine, and the bone marrow, where they serve in the regeneration of old or worn tissue. In cancer treatment, blood-forming adult stem cells are routinely harvested from bone marrow, stored, and then reinfused into patients to replace blood cells destroyed by chemotherapy or radiation therapy. This potential for replacing damaged tissues has aroused great interest in using embryonic stem cells to treat a number of other conditions, such as Parkinson disease, severe burns, and damage to the spinal cord. Mouse embryonic stem cells are widely used to create genetically modified mice that serve as models for investigating human disease. However, the use of human embryonic stem cells, which requires destroying the blastocysts from which they are obtained, has raised objections by those who feel blastocyst-stage embryos are human beings. The first human stem cell line was created in 1998, using cells harvested from embryos produced through in vitro fertilization. The use of human embryonic stem cells is allowed in some countries and prohibited or restricted in others.

Current treatments

For over 30 years, bone marrow, and more recently, umbilical cord blood stem cells have been used to treat cancer patients with conditions such as leukemia and lymphoma.

Thyroid - Hypothyroid - Meaning - Causes - Symptoms - Treatment

What is Hypothyroid? Hypothyroidism is a condition in which the body lacks sufficient thyroid hormone. Since the main purpose of thyroid hormone is to "run the body's metabolism," it is understandable that people with this condition will have symptoms associated with a slow metabolism. Causes About three percent of the general population is hypothyroidic. Factors such as iodine deficiency or exposure to Iodine can increase that risk. There are a number of causes for hypothyroidism. Iodine deficiency is the most common cause of hypothyroidism worldwide. In iodine-replete individuals hypothyroidism is generally caused by Hashimoto's thyroiditis, or otherwise as a result of either an absent thyroid gland or a deficiency in stimulating hormones from the hypothalamus or pituitary.

Warts - Meaning - Causes - Treatment

A wart is generally a small, rough tumor, typically on hands and feet but often other locations, that can resemble a cauliflower or a solid blister. Warts are common, and are caused by a viral infection, specifically by the human papillomavirus and are contagious when in contact with the skin of an infected person. It is also possible to get warts from using towels or other objects used by an infected person. They typically disappear after a few months but can last for years and can recur. Cause Warts are caused by a virus called human papilloma virus or HPV. There are approximately 130 strains of human papilloma viruses. People with week immune system are at the greater risk of this disease. Will warts go away on their own? Often warts disappear on their own, although it may take many months or even years for the warts to go away. But some warts won't go away on their own. Doctors are not sure why some warts disappear and others do not. Treatment Warts can be remov...

Choking

Choking is the kind of emergency in which the chance of getting the victim to a doctor in time is almost nil. Without immediate help, the person can die, or at least suffer permanent brain damage, within four minutes. That is all the more reason for you to keep your wits about you and familiarise yourself with the skills and techniques that might one day save a life - including your own. Cough it out: If the airway is only partially obstructed, violent coughing and sputtering will generally dislodge the obstructing mass. Perform the Heimlich manoeuvre: If the victim is not getting air, and his/her throat is blocked, don't wait for medical help. Take first-aid steps for choking immediately. Stand behind the victim and wrap your arms around his waist. Place your fist with the thumb side against the victim's abdomen slightly above the navel and below the rib cage. Grasp your fist with your other hand and pull it into the victim's abdomen with a quick upward thrust. Repe...
