Some of the world’s top scholars on modern human origins will gather March 26 at Washington University in St. Louis for the last of a four-part series of “Conversations” on key issues that will affect the future of the university, the community and the world. Arts & Sciences is sponsoring the “Conversations,” which are free and open to the public, as part of the university’s 150th anniversary celebration. The “Modern Human Origins” Conversation will be held from 10 to 11:30 a.m. in Graham Chapel.

Two international research teams — one led by M. Alan Permutt, M.D., professor of medicine and of cell biology and physiology at Washington University School of Medicine in St. Louis — have found variations in a gene that may predispose people to type 2 diabetes, the most common form of the disease. The two research teams, which collaborated extensively, will report their findings in companion articles in the April issue of Diabetes.

The results of an experimental cross-species transplant suggest the innovative approach might halt type 1 diabetes while greatly reducing the risk of rejection. Click here for more medical articles

A team of scientists reports a major advance in seqencing large genomes.A team of scientists that includes a Washington University in St. Louis biologist, has evaluated and validated a gene-enrichment strategy for genome sequencing and has reported a major advance in sequencing large genomes. The team showed a six-fold reduction of the effective size of the Zea mays (maize or corn) genome while creating a four-fold increase in the gene identification rate when compared to standard whole-genome sequencing methods.

To meet design and cost changes, industry and government are considering clockless computing.Computing royalty, including Ivan Sutherland, the father of computer graphics, and Wesley A. Clark, the designer of the world’s first personal computer, will gather at a computing symposium Friday, March 26th, 2004, from 1:00-5:30 p.m. at Washington University in St. Louis’s Whitaker Hall Auditorium. As part of the University’s 150th anniversary of its founding, participants will honor time by contemplating how computing can evade time as the industry prepares to go clockless.

Strong stitches attach the rotator cuff directly to the shoulder bone.Each year in the United States, nearly 300,000 people have surgery to repair their rotator cuff. The rotator cuff is made up of several muscles that allow us to lift our arms or to rotate them during sports activities such as golf, tennis and swimming. The rotator cuff also is used during lifting, washing windows and working in the garden. In the past, surgical correction of the rotator cuff involved an incision through the deltoid muscle on the outside of the shoulder, a lot of pain for weeks after surgery and a long period of recovery. But Washington University orthopaedic surgeons have begun using a minimally invasive system that eliminates the need for the incision through the muscle and limits the amount of post-operative pain. The system allows surgeons to strengthen the repair with a suturing device that sews the muscle right into bone where it can heal more quickly, with less pain.

A fluroescent-tagged antibody bearing silver and gold particles reveals I and L bradykinin receptors lit in a ghostly green glow on the surfact of cultured human cellsPreliminary research suggests it may someday be possible to diagnose and forecast risk for Alzheimer’s disease using skin cells, thanks to a small protein, or peptide, that few previously associated with the disease. Researchers at Washington University School of Medicine in St. Louis have discovered that skin cells from people with inherited forms of Alzheimer’s disease respond to the peptide by triggering Alzheimer’s-like changes, but skin cells from healthy individuals do not. They say the findings need to be explored further in cases of non-inherited Alzheimer’s disease, but the results could eventually lead to a way of determining an individual’s risk of developing Alzheimer’s before clinical symptoms arise.

Kidney recipient Barry Hammond (left) and his brother, kidney donor Brian.More than 50,000 people in the United States are waiting for kidney transplants. Most are waiting for someone who wants to be an organ donor to die, but each year only 9,000 people on the transplant waiting list get a kidney from someone who has died, while 16,500 on the list die. Transplants from living donors have the greatest chance of working for a long time and can happen quickly, often within a year. A living kidney donor may be a family member or friend between the ages of 18 and 65. They must be healthy and have a blood type that is compatible with the recipient’s blood type. But researchers at Washington University School of Medicine, have discovered something surprising. Many interested kidney donors are not taken up on their offers to donate because the recipients are afraid donors will be harmed. As a result, many potential donor kidneys go unused.
