A gene on chromosome 20p13 that encodes a ubiquitous immunoglobulin-like cell surface receptor for CD47 that acts as a docking protein and induces translocation of PTPN6, PTPN11 and other binding partners from the cytosol to the plasma membrane. SIRPA supports adhesion of cerebellar neurons, neurite outgrowth and glial cell attachment, and may play a key role in intracellular signalling during synaptogenesis and in synaptic function. It downregulates receptor tyrosine kinase-coupled cellular responses induced by cell adhesion, growth factors and insulin; it also downregulates phagocytosis, mast cell activation and dendritic cell activation. CD47 binding prevents maturation of immature dendritic cells and inhibits cytokine production by mature dendritic cells. It is highly expressed in the brain.


Abbreviation for behavioral inattention test.


1. the detachable piercing piece of a drill.
2. the metal part of the bridle that goes into the horse's mouth and over the tongue; used to restrain and direct the horse by exerting pressure on the attached reins.

Patient discussion about bit

Q. Don’t you feel a bit insincere? I work as a nurse in the ER, and last night a well-known alternative “healer” came to the ER with complaints of bellyache (which turned out to be kidney stones). Now I wouldn’t mind that, except that this healer always speaks against using painkillers and claims that doctors don’t treat the person as a whole like he does. He has no shame to convince patients to avoid hospitals, but when it comes to his own body, he doesn’t seem to believe in his own medications. It’s so frustrating!

A. well, i'm not sure about what line of alternative healing this guy practice but from what i know - the main idea is that alternative healing is usually for preventing illnesses, and it's very good at it. it's main effort is changing way of life and restoring balance. but it will never compare to western medicine on emergency treatments. it's wise to avoid taking pain killers - but it's wiser to take them if you really need it. today people in the U.S take medicines like they were candy and every medicine has side effects.
my brother is an MD and studied Chinese medicine - he practice both and there is a great advantage in using both to complete the therapy.

Q. if a bee bit me and i am allergic , what would happen to me , and what is the best treatment?

A. It depends on your previous exposure and response to the bee sting, but it may result in a severe, life threatening response called anaphylaxis. It includes intense itching and rash, runny nose and mouth, abdominal cramps, vomiting, but the life threatening responses are the closure of the throat and airways and collapse of the heart. It's treated with adrenalin and other medications.

It can be prevented first by avoiding the offending agent, and also by carrying an ready to use adrenalin injector in order to treat it quickly. Also, the allergy can be ameliorated by a series of treatments called immunotherapy, in which the allergic individual is exposed to the allergen in minute amount to make him or her not sensitive any more to this allergen.

Q. I want to understand why these differences? I'm new to this, and a bit lost... I have indication of mastectomy plus post-mastectomy radiation. I've heard of women in my situation that were prescribed chemo and that's it. No radiation and no breast removal. My doctor said this is not an option for me, but didn't explain anything, although I insisted. I want to understand why these differences? I'm new to this, and a bit lost...

A. You know I got an oncologist who explained me on these. Let me tell you. I was on my last stage of breast cancer. I did chemo followed by right modified radical mastectomy with lymph node dissection followed by radiation. I will continue to take Herceptin and Zometa for the rest of my life. You will have breast removal and then radiation which means your cancer might be at an advanced stage. Removal is done to remove the tumor and radiation to kill cells which may enter other body parts. In your case it’s entered into other body parts so they are using radiation as the best treatment for you.
