First implantable artificial kidney could remove demand for dialysis and donor organs

Around 45,000 adults in the UK undergo dialysis. However, the treatment only replaces 13 per cent of kidney function.
An artificial kidney that would be implanted inside the body and work as well as a living organ is just around the corner, scientists have revealed.
U.S researchers have just unveiled the first prototype model of the device, that could eliminate the need for dialysis.
It would include thousands of microscopic filters to remove toxins from the blood and a bioreactor to mimic the metabolic and water-balancing roles of a real kidney.
The kidney is being developed in a collaborative effort by engineers, biologists and physicians led by Dr Shuvo Roy at the University of California San Francisco.
The treatment has already been proven to work for the sickest patients using a room-sized external model.
The process relies on the body's blood pressure to perform filtration without needing pumps or an electrical power supply.
Dr Roy plans to apply silicon fabrication technology, along with specially engineered compartments for live kidney cells, to shrink the current device to the size of a coffee cup.
Tissue engineering will be used to grow renal tubule cells to provide other biological functions of a healthy kidney. This would remove the need for immune suppressant medications after it was implanted, allowing the patient to live a more normal life.
'This device is designed to deliver most of the health benefits of a kidney transplant, while addressing the limited number of kidney donors each year,' said Dr Roy
'This could dramatically reduce the burden of renal failure for millions of people worldwide.'

In the UK, there are less than 2,000 kidney transplants carried out each year - which is less than one in three of the patients waiting for a donor kidney.
The alternative treatment for kidney failure is dialysis. A patient will have their blood filtered in three long sessions a week. It is exhausting for patients and only replaces 13 per cent of kidney function. .
There are just over 45,000 adult patients receiving dialysis in the UK. Only 35 per cent of patients survive for more than five years with this treatment.
The team has established the feasibility of an implantable model in animal models and plans to be ready for clinical trials in five to seven years.

WARNING FROM RAEL: For those who don't use their intelligence at its full
capacity, the label "selected by RAEL" on some articles does not mean that I
agree with their content or support it. "Selected by RAEL" means that I believe
it is important for the people of this planet to know about what people think or
do, even when what they think or do is completely stupid and against our
philosophy. When I selected articles in the past about stupid Christian
fundamentalists in America praying for rain, I am sure no Rael-Science reader
was stupid enough to believe that I was supporting praying to change the
weather. So, when I select articles which are in favor of drugs, anti-semitic,
anti-Jewish, racist, revisionist, or inciting hatred against any group or
religion, or any other stupid article, it does not mean that I support them. It
just means that it is important for all human beings to know about them. Common
sense, which is usually very good among our readers, is good enough to
understand that. When, like in the recent articles on drug decriminalization, it
is necessary to make it clearer, I add a comment, which in this case was very
clear: I support decriminalizing all drugs, as it is stupid to throw depressed
and sad people (as only depressed and sad people use drugs) in prison and ruin
their life with a criminal record. That does not mean that there is any change
to the Message which says clearly that we must not use any drug except for
medical purposes. The same applies to the freedom of expression which must be
absolute. That does not mean again of course that I agree with anti-Jews,
antisemites, racists of any kind or anti-Raelians. But by knowing your enemies
or the enemies of your values, you are better equipped to fight them. With love
and respect of course, and with the wonderful sentence of the French philosopher
Voltaire in mind: "I disapprove of what you say, but I will defend to the death
your right to say it".
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
"Ethics" is simply a last-gasp attempt by deist conservatives and
orthodox dogmatics to keep humanity in ignorance and obscurantism,
through the well tried fermentation of fear, the fear of science and
new technologies.
There is nothing glorious about what our ancestors call history,
it is simply a succession of mistakes, intolerances and violations.
On the contrary, let us embrace Science and the new technologies
unfettered, for it is these which will liberate mankind from the
myth of god, and free us from our age old fears, from disease,
death and the sweat of labour.
