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.

Sweden’s “tiger economy” close to being tamed as growth bounces to zero
Tuesday, 14 February 2012
As the heavy cloud over the European economy gets thicker and darker,
SEB’s economists predict that even Swedish economic growth will bounce
to near zero growth this year.
Some international lines of light can still see coming from the growing
stronger economic signals from the U.S. and China. At the same time,
central banks around the world are now under pressure to print
new money at an accelerating pace in order to gain momentum in the
international economy.
“The problems in Europe remain, but thankfully there are central banks,
which now provide a historical relief. They create time, but it remains
to be seen whether the political systems can solve problems in that
time,” says SEB’s Chief Economist, Robert Bergqvist.
SEB’s economists expect a continued weak GDP growth in Sweden in the
shadows of the uncertain situation in Europe. It stays at lead expect a
0.5 percent growth this year and tat there should be the expectation of
increased unemployment to continues to rise.
“We are in a recession and we expect that we should reach the bottom
perhaps by the summer and that it then gets better but at a slow pace,”
says Bergqvist.
SEB expects the the Swedish central bank, the Riksbank should to cut the repo rate by about 1.0 per cent.
