What website is best for the "latest technology that can cure ailments of circulatory and nervous system"?

Question

we have a project in Science and we have to find 6 latest inventions that can cure the ailments of circulatory and nervous system. I find it really difficult to search for the websites..

Answer 1

6 LATEST inventions for circulation and nervous system!

I don't think there is the one website you could try unless it is Yahoo! Answers.

Intra-Aortic Balloon Pump (IABP) is a counterpulsation pumping device - essentially a big balloon that is placed INSIDE the patient's aorta and inflated in time (just after systole) to help push blood around the circulation. This is used in some patients where their heart is not pushing well by itself (eg after cardiac surgery).

"Octopus" cardiac suction clamp for beating heart surgery - This is a recent development in heart surgery. In the past, in order to sew a bypass graft onto a heart or major blood vessel it has been necessary to give the heart medication to make it stop beating. This is so the surgeon could put in extremely fine stitches in the right place. This would necessitate the patient being placed on CardioPulmonary Bypass - a separate machine which keeps pumping blood around the patient's body. This new technology, the "octopus clamp" is essentially a suction clamp that holds one part of the heart very very still so the heart can still be beating and the surgeon can sew the graft onto the heart.

Endoluminal Aortic Stent/Graft
In a diseased and weakened aorta - the traditional technique to replace the weakened section has been to open up the abdomen from the front, get past all the intestines and such, find the aorta, clamp it off and cut out the weak bit and sew in the graft. However, in certain circumstances new technology allows the graft to be inserted from a smaller cut in the groin where the graft can be fed up the aorta "endoluminally" ie. inside the aorta. The stent can be deployed to cover the weakened area and attached securely from inside the blood vessel. This is a much smaller procedure and if patients are suitable for this type of operation they tend to do much better in terms of recovery.

Let me have a think about some nervous system advances.

Okay

Stereotactic Radiotherapy - "Radiosurgery", "Gamma Knife" - is a relatively recent advance in treatment of brain cancers where instead of a few beams of radiation aimed at the cancer, the radiotherapists use multiple very low dose beams which are very accurately aimed so that each subsequent beam passes through the cancer, but passes through a different part of the patient's brain. Hence most of the brain gets a very low dose, but the cancer gets a mega dose of radiation and dies.

Thrombolytic therapy for Stroke
When a clot blocks off a part of the blood supply to the brain, that part of the brain loses oxygen and glucose and doesn't function. This condition is commonly known as a "stroke". Recent advances have suggested (although not entirely proven) that clot busting drugs, similar to the clot busting drugs given previously for heart attacks, could dissolve these clots and allow blood flow. Actually, we've know about the possibility of this for as long as we've had the clot busting drugs - the major problem is that these drugs can cause bleeding in the brain! So the advances really are to do with selecting the appropriate patients who will do well with this type of therapy based on clinical features (recent onset, not likely to be a bleed, etc) as well as advanced brain scanning techniques. Further to this, in 2004, a team from Texas is pioneering the use of ultrasound to enhance clot busting (don't ask me how they get the ultrasound through the skull)!

Gene Therapy Advances for Parkinson's Disease
Parkinson's Disease is a disorder of a part of the movement section of the brain. People who suffer from it have terrible tremors and difficulty performing day-to-day activities. Treatment to date has centered around giving them tablets that boost levels of or replace the neurotransmitter in that region of the brain. Newer approaches that are showing promise include a technique where a very fine tube is inserted through a hole made in the skull. This tube is placed in the movement section and a specially engineered virus is delivered through it. This virus is designed to insert a gene into the cells, and this gene enables the cells to make a certain chemical messenger to calm down overactive movement signals and hence reduce the symptoms of Parkinson's Disease. It is still experimental.

Answer 2

I would cure my sister of her biopolar as well. There are (or I shoud say were) times that she would be the most wonderful, caring creative person. She was my best friend. Through the years she has gotten so progressivly worse and she will not even seek treatment. 2 years ago she hit rock bottom I supppose when her and her kids were staying with me and she quietly slipped out the back door, leaving her kids behind. To make a long story short it isn't so much the fact that now we have six kids to raise that bothers me; its that I lost my best friend...thats what hurts the most. The thing is she is still in town and I hear about her all the time. LOL through possibly some cosmic force I have yet to see her myself, luckily. I am filled with such pain and anger over her it is probably better that way. However Sunday we went to get a family portrait done at Wal-Mart (all 8 of us) and my sister was there. My oldest son was taking her youngest to the bathroom and they saw her. The thing is she turned around and saw her daughter and ran. I will never understand how a mother can actually run and hide from her own child. *On a side note these are the questions that keep me coming here. The ones where we can share on deepest sorrows and our greatest joys...our spiritual journey so to speak. I have been getting violation notices on roughly 50% of my questions and I was prepared to come in here today with guns blazing! This however was the very first question I saw...
