June 21, Baku police detained Mamedov, editor of the minority newspaper Talyshi Sado Voice of the Talyshon June 21,alleging they had found drugs, about five grams of heroin, in his pocket, the Azeri-language service of the U. Following his arrest, Baku police declared that they had found an additional 30 grams of heroin in Mamedov's home, which they searched the same day, news reports said. A day later, a district court in Baku ordered Mamedov imprisoned for three months before trial on drug possession charges, the reports said.

There are two types of HSCT. These are allogeneic and autologous. Doctors performing this type of HSCT need to ensure that the donor is an appropriate match for a recipient. Often, this is a close relative, although other donors, matched through tissue typing, are also used.

Proteins known as human leukocyte antigens HLA are used in tissue typing. They allow clinicians to compare a person's blood and tissue type with blood samples from possible donors. In this way, they can check to see if a donor's stem cells are the right match.

Allogenic HSCT often requires a donor from the patient's close family. As well as using stem cells from a donor's blood, cells from umbilical cord blood can also be used.

Umbilical cord stem cells are less developed than other stem cells, and this means that they can grow into different types of cells.

Umbilical cord blood stem cells are frozen at birth, which is important because they do not suffer any environmental damage or aging.

As a result, cord blood transplants do not require such a high level of tissue matching. The cells are cleaned and frozen before being reintroduced to the individual after they receive the chemotherapy drugs. In fact, the key element is an infusion of chemotherapy drugs.

There are two types of transplantation process, known as myeloablative and nonmyeloablative. Myeloablative includes the use of high-dose chemotherapy drugs to destroy the immune system.

Nonmyeloablative uses lower-dose, more tolerable chemotherapy drugs to suppress the immune system. High doses of chemotherapy are needed to treat cancers.

In both processes, the stem cells are transplanted after the chemotherapy drugs are administered to help build a new, and hopefully healthy, immune system.

Lower doses of chemotherapy have been found to be successful in dealing with autoimmune diseases, such as multiple sclerosis. Risks and complications The donor may be advised to take iron supplements after the procedure to boost their red blood count.

Another risk associated with allogeneic stem cell transplant is graft-versus-host-disease GVHDwhich occurs when donated cells attack a person's tissues. The lower the match of tissue type between patient and donor, the higher the risk of GVHD.

Doctors may use drugs to reduce the possibility of infection or GVHD. For a surgical procedure, there are not too many risks for donors to worry about. Also, it is rare to encounter serious complications.

This discomfort may be relieved with over-the-counter acetaminophen and nonsteroidal anti-inflammatory drugs NSAIDssuch as ibuprofen.

Doctors may suggest that donors should take iron supplements until their red blood cell count returns to normal. Many donors can return to their daily routine after 2 to 3 days rest. In some cases, however, full recovery can take 2 to 3 weeks. Research into treating autoimmune diseases Different studies have reached different conclusions about the use of HSCT for autoimmune diseases.

Canada reported the results of a clinical trial of autologous HSCT as a great success.


In this studyseverely disabled people with multiple sclerosis were reported to be walking, cycling, and even skiing after treatment. The story made newspaper headlines around the world.

Other researchers from University Hospital Basel, Switzerland, had previously looked at various difficulties encountered by people who have autologous HSCT as a treatment for autoimmune diseases.The viewer is a powerful tool that lets you explore a newspaper page Articles · Photos · From the 's to 's · Access + million pages3,+ followers on Twitter.
