Researchers at the Sahlgrenska University Hospital in Göteborg have
managed to implant a blood vessel made from a patient’s own stem cells
in a ten year old, sick girl. One year after surgery she now is doing
pretty fine making the researchers to hope that this could be a method
to assist patients who need bypass surgery.
The process involves approach, in making the vein perform better
took three to four weeks, according to Michael Olausson, a professor at
the Transplantation Center at the hospital. The vein for the girl was
obtained from a donation from a deceased person, reports radio Sweden. “Then we have
removed all cells and all the genetic material, and after that we have
brought stem cells from the patient who will receive the blood vessel
and then grow this vessel out again,” says Michael Olausson, Professor
and Director of the Transplant Center at the Sahlgrenska University
Hospital in Gothenburg to radio Sweden.
At the moment, Michael Olausson and his team believe that the approach
could be of great help to many people with plug formation in their
blood vessels and that they need to undergo a so-called "bypass
surgery".
Asked how important is it that the patient's own stem cells are
included in the vein? Michael Olausson replied that it has to do with
the immune system recognizing the tissue as its own and thus will not
reject it. For him and the patient, it's a big advantage. All the
medications that are normally given to avoid the body rejecting the new
cell is very powerful and can cause side effects, so it is desirable to
avoid them.
He adds that this new method is also very important so that “we’ll be
able to solve problem around such things as hearts or kidneys in the
future. The next big step for us is probably a work around to get
arteries to function well. This opens the door and then maybe, be able
to produce whole organs,” says Michael Olausson.

Swedish central Banks could reduce key interest rates soon but how would that affect?
Tuesday, 14 February 2012
On Thursday it is expected that the Swedish central, the Riksbank’s
governor, Stefan Ingves, again will lower the Swedish policy rate. But
the general expectation now is that the expected lower mortgage rates
could be a distant perception.
On the whole, more are leaning towards that the Riksbank will cut its
repo rate, probably to 1.5 percent from the current 1.75 percent. More
rate cuts are expected later this year, as the economy weakens.
On Thursday the first rate notice from the Riksbank will come.
The day before holding the Executive Board’s monetary policy meeting,
which is peculiar in that two new members are involved in the decision
– Kerstin af Jochnick and Per Jansson, who took office at the end.
It is likely, however, that the Governor Stefan Ingves can rally a
majority around his relatively tight line. The interest rate cut, is
now expected by many analysts to be viewed as entirely obvious but to a
very less extent. The current interest rate path, which the Executive
Board held in December, which was pointing to an unchanged level could
be held also.
What ever the case may be, the common man is likely not going to feel
the effect of any cut as the general consensus now is that those cuts
are doing to satisfy the banks. When the rates where cut last December,
banks raised their interest rates and it seems this is what will happen
this time. That means the news that the central bank might cut interest
rates would make commercial banks to raise theirs. Then after the
central banks has cut its repo rates, the banks will then reduce their
rates by a tiny level which will still give then a well calculated gain.
