Umbilical cord blood may safely preserve insulin production in children newly diagnosed with type 1 diabetes, according to findings from a small national pilot study .
University of Florida researchers sought to determine whether it is feasible to use a patient’s own cord blood stem cells to neutralize the body’s autoimmune attack on the pancreas and help restore the organ’s ability to make insulin, which regulates how the body uses sugar and other nutrients for energy.
“This is the first attempt at using cord blood as a potential therapy for type 1 diabetes. We hope these cells can either…
Treatment with intravenous bisphosphonates — drugs used to reduce harm done to bones by cancer or cancer therapy — increases the risk of jaw or facial bone disease or infection, a large-scale comparative study by researchers at the University of Texas Medical Branch at Galveston (UTMB) has found.
Drawing on the National Cancer Institute’s Surveillance, Epidemiology and End Results (SEER) database linked to Medicare insurance claims, investigators from the UTMB Center for Population Health and Health Disparities compared more than 14,000 cancer patients treated with two types of intravenous…
Researchers at UT Southwestern Medical Center have determined how a substance derived from the bark of the South American lapacho tree kills certain kinds of cancer cells, findings that also suggest a novel treatment for the most common type of lung cancer.
The compound, called beta-lapachone, has shown promising anti-cancer properties and is currently being used in a clinical trial to examine its effectiveness against pancreatic cancer in humans. Until now, however, researchers didn’t know the mechanism of how the compound killed cancer cells.

Topotecan, a cancer inhibitor, interacts with an important protein (TopoIB), causing a (cancer) cell to malfunction. The TopoIB protein is responsible for the removal of loops from DNA, which arise amongst other things during cell division.
The TopoIB protein binds to the DNA molecule, clamps around it and cuts one of the two DNA strands, after which it allows it to unwind and finally joins the broken ends together.
Until now it has been supposed that topotecan only causes the TopoIB protein to reside longer than normal on the DNA molecule, disturbing the cell division and damaging the (…
It has long been known that eating potatoes is good for bowel health, but new research suggests that they may also have a beneficial effect on the whole immune system. Especially if eaten cold or in a potato salad, Anne Pichon reports in Chemistry&Industry.
Spanish researchers found that growing pigs fed large quantities of raw potato starch (RPS) had a healthier bowel. Not a surprise, but they also found that RPS pigs had decreased levels of white blood cells, such as leucocytes and lymphocytes in their blood. White blood cells are produced as a result of inflammation or disease,…
Pediatricians now have a practical tool to help determine whether children with chronic diseases like Crohn’s, juvenile arthritis and anorexia nervosa – or those undergoing cancer treatment – are at increased risk for bone mass deficiencies, fracture or osteoporosis as they get older, according to a new study.
“There is a huge demand for this information among clinicians because in almost any chronic condition in children affecting growth, inflammation, or involving cancer survivors, they have problem bones,’’ said Heidi Kalkwarf, Ph.D., associate professor of Community and General Pediatrics…
Misstatements and ignorance claiming that families "cause" eating disorders is like blaming parents for diabetes or asthma or cancer says an international group of eating disorders researchers.
Recent damaging statements by fashion model Gisele Bundchen stating that unsupportive families cause anorexia nervosa only perpetuate misconceptions and further stigmatize eating disorders.
Contrary to her claim, there is no scientific evidence that families cause anorexia nervosa. In fact, the researchers are finding that anorexia nervosa is far more complex than simply wanting to be slim to achieve…
Tissue Regeneration Therapeutics Inc. will exclusively license its human umbilical cord perivascular cell (HUCPVC) technology to Stem Cell Authority Ltd. for family stem cell banking in the U.S.
The technology originated at the University of Toronto and has been offered to the public in Canada since March 2007 through a licensing agreement between TRT and Toronto-based CReAte Cord Blood Bank (CCBB).
“Toronto is the first place in the world to bank perivascular mesenchymal stem cells from the human umbilical cord and we are extremely pleased to now be able to provide this opportunity to…
A team of researchers, led by surgeons at the Kimmel Cancer Center at Jefferson in Philadelphia, has found further evidence supporting the ability of a protein to predict how well a patient with advanced pancreatic cancer will do after surgery, chemotherapy and radiation. The levels of the protein CA 19-9 in the blood can be used to determine the need for further therapy, they say.
Adam Berger, M.D., assistant professor of surgery at Jefferson Medical College of Thomas Jefferson University, and his co-workers examined CA 19-9 levels and the survival of 385 patients with advanced pancreatic…
