How do you make a working human heart? Scientists can turn stem cells into beating heart cells, but getting them to organize into a 3D heart requires a scaffold. At the Massachusetts General Hospital in Boston, Harald Ott and his team are reusing the scaffold that nature provides. They’re stripping away all the living cells from dead hearts, before filling in the leftover matrix with healthy new cells. In this video, Brendan Maher finds out how the technique could be used to develop parts of the heart, like the aortic root and valve, for transplant.

Thalassemia is an inherited blood disorder characterized by less hemoglobin and fewer red blood cells in your body than normal. Several types of thalassemia exist, including alpha-thalassemia, beta-thalassemia intermedia, Cooley's anemia and Mediterranean anemia. Hemoglobin is the substance in your red blood cells that allows them to carry oxygen. The low hemoglobin and fewer red blood cells of thalassemia may cause anemia, leaving you fatigued. If you have mild thalassemia, you may not need treatment. But, if you have a more severe form of thalassemia, you may need regular blood transfusions. You can also take steps on your own to cope with fatigue, such as choosing a healthy diet and exercising regularly.

Urinary incontinence is the unintentional loss of urine. Stress incontinence happens when physical movement or activity — such as coughing, sneezing, running or heavy lifting — puts pressure (stress) on your bladder. Stress incontinence is not related to psychological stress. Stress incontinence differs from urge incontinence, which is the unintentional loss of urine caused by the bladder muscle contracting, usually associated with a sense of urgency. Stress incontinence is much more common in women than men. If you have stress incontinence, you may feel embarrassed, isolate yourself, or limit your work and social life, especially exercise and leisure activities. With treatment, you'll likely be able to manage stress incontinence and improve your overall well-being.

It is characterized by the formation of solid tumors in the immune system.1 The cancer affects immune cells called lymphocytes, which are white blood cells.

Surgery is done to relieve pressure on the nerve roots. This can help reduce pain, numbness, and weakness in your legs. Surgery may be recommended if: Your pain, numbness, or weakness is so bad that it gets in the way of normal daily activities and hurts your quality of life. You are in otherwise good health. The goal of surgery is to relieve pain, numbness, or weakness in the legs-not to relieve back pain. People who have surgery only for back pain are less satisfied with the results than are those who have surgery for nerve root symptoms and pain in both the back and legs. Also, numbness, weakness, and pain may return after surgery.

A cluster headache commonly awakens you in the middle of the night with intense pain in or around one eye on one side of your head.

Treatments can make cluster headache attacks shorter and less severe. In addition, medications can reduce the number of cluster headaches.

This video, Rheumatoid arthritis is a chronic inflammatory disorder that can affect more than just your joints. In some people, the condition also can damage a wide variety of body systems, including the skin, eyes, lungs, heart and blood vessels. An autoimmune disorder, rheumatoid arthritis occurs when your immune system mistakenly attacks your own body's tissues. Unlike the wear-and-tear damage of osteoarthritis, rheumatoid arthritis affects the lining of your joints, causing a painful swelling that can eventually result in bone erosion and joint deformity. The inflammation associated with rheumatoid arthritis is what can damage other parts of the body as well. While new types of medications have improved treatment options dramatically, severe rheumatoid arthritis can still cause physical disabilities.
