Study Shows The Negative Side To Positive Self-Statements In Self-Help Books
In times of doubt and uncertainty, many Americans turn to self-help books in search of encouragement, guidance and self-affirmation. The positive self-statements suggested in these books, such as "I am a lovable person" or "I will succeed," are designed to lift a person"s low self-esteem and push them into positive action. According to a recent study in Psychological Science, a journal of the Association for Psychological Science, however, these statements can actually have the opposite effect.

Drug Crimes In Canada Cause Continuing Problems For Small Communities
The Narconon drug rehab program has noticed a trend of many drug addicts being involved with drug related charges due to their addiction. "You can have the everyday functioning addict who is battling a drug addiction, and just one day gets caught by police for possession of a small amount," comments Nick Hayes, a representative of Narconon Trois-Rivieres. "This is an all too common situation for many people who are involved in a drug addiction." More people are using illicit drugs in Canada, in fact Trois-Rivieres, Quebec, Canada, where the Narconon drug rehab program is located, is one of the leading cities in Canada for drug crimes. "There are so many youth in Trois-Rivieres who are addicted to different drugs like speed, ecstasy, marijuana, and even cocaine. These teens get caught up with the law and start heading down the wrong path at a very young age," says Nick.

Canadians Watch U.S. Reform Effort Closely
American health care reform has become a "hot topic north of the border," the Washington Times reports. "If Mr. Obama succeeds, the U.S. could draw even more Canadian doctors and nurses to the U.S., exacerbating a shortage of medical professionals, said Dr. Brian Day, a Canadian health care critic and former head of the Canadian Medical Association. If Mr. Obama fails, perhaps Canada could open its system to "medical tourism" from the U.S., Dr. Day said." Under the Canadian system, everyone is insured and has "access to basic health care without ever seeing a doctor or hospital bill." But 70% of Canadians also have "some form of supplemental health insurance," in part because of long wait times for tests and treatments under the government plan. For Canadian citizens who become ill in the U.S., it is often cheaper to "ride on a private Lear jet back to Canada" than to be treated in a U.S. hospital.

Stem Cell Discovery May Bring Tissue Repair Closer

The goal of creating adult blood stem cells from human embryos to prepare a patient for tissue and organ transplant has been brought a step closer by research carried out at the MRC Molecular Haematology Unit at Oxford University. Blood, or haematopoietic, stem cells (HSCs), are a type of adult stem cell that can produce several different types of blood cell, including those of the immune system that are involved in tissue rejection. Scientists have so far been unable to generate HSCs from embryonic stem cells, largely because they have not known how the embryo makes these cells. By studying zebrafish embryos, the research team found BMP4, a protein involved in bone and cartilage development, to be the critical signal required to generate HSCs in the dorsal aorta, which is the chief artery that arises from the heart to distribute blood to the body. Lead author Professor Roger Patient, from the MRC Molecular Haematology Unit, said: "The ability to make adult stem cells from embryonic stem cells would obviously benefit regenerative medicine because one of the characteristics of adult stem cells is that they are present in very small numbers and are resistant to expansion. "There is substantial evidence for conservation of genetic mechanisms among vertebrates. Human embryos for example have been shown to express BMP4 under the dorsal aorta as seen in zebrafish. Zebrafish provide a large number of externally developing, and therefore manipulable, embryos that are transparent, allowing developmental processes to be observed in great detail." One of the benefits, in the specific case of HSCs, is the potential for preparation of patients for transplantation. Another benefit is that numbers are always limited, even from bone marrow or umbilical cord. Therefore an alternative, potentially limitless could be of great clinical benefit. Notes - This paper, Hedgehog and Bmp Polarize Hematopoietic Stem Cell Emergence in the Zebrafish Dorsal Aorta, is in the June edition of Developmental Cell. - Other centres involved in the research included Department of Chemistry, Chemistry Research Laboratory; Department of Pharmacology, Oxford University; Institute of Genetics, Queens Medical Centre, Nottingham University; Department of Biochemistry, Washington University; Centre for Developmental and Biomedical Genetics, Sheffield University.
