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 export of military hardware continues to hold as the past
Wednesday, 22 February 2012
In 2011, Swedish companies exported military equipment for some Skr13.9
billion. It is basically the same as last year, according to the
Swedish organisation, the National Inspectorate of Strategic Products
(ISP).
“As in previous years there are also a few large deals that dominated.
In 2011, it is about the export of the Jas 39 Gripen to Thailand and
the airborne surveillance system Erieye to the United Arab Emirates,
Saudi Arabia and Pakistan, ” that accounted to the great gains, said
the ISP’s Director General to Swedish daily, Dagens Nyheter .
63 percent of Swedish exports of military equipment in 2011 wents to
more than 20 countries, including Thailand, Saudi Arabia, India,
Pakistan and the UAE accounted for 60 percent. With the exception of
exports to the UAE and Saudi Arabia, Swedish export of armaments to the
Middle East and North Africa was limited. 37 percent went to other EU
countries, and established partner like the U.S., Canada and South
Africa.
Swedish Peace and Arbitration Society have criticized the fact that
Swedish arms exports to dictatorships increased. This follows new
statistics showing that a fifth of the Swedish arms exports went to
Saudi Arabia, writes the organisation in a statement.
“Export statistics show that the Swedish exports rules are constantly
undermined. When Saudi Arabia, the world’s most brutal dictatorships,
bought weapons forSkr2.9 billion in Sweden, it is difficult to see what
purpose the rules are for, “said President Anna Ek in a statement.
Swedish Peace and Arbitration Society believe that the export of
Swedish weapons is “rampant” in the political vacuum that currently
exists in many parts of the world.
