Experimental immunusuppressant drug preserves transplanted kidneys, avoids toxic side effects
An international team of transplant physicians has shown that the investigational drug belatacept (LEA29Y) preserves transplanted kidney function as effectively as cyclosporine, the drug most commonly used to prevent the immune system from rejecting transplanted organs. view more (2005-08-25)
Liver regeneration may be simpler than previously thought
The way the liver renews itself may be simpler than what scientists had been assuming. A new study, appearing in the April 13 issue of The Journal of Biological Chemistry, provides new information on the inner workings of cells from regenerating livers that could significantly affect the way physicians make livers regrow in patients with liver... view more...

Scientists uncover how hormones achieve their effects
New insights into the cellular signal chain through which pheromones stimulate mating in yeast have been gained by scientists at the European Molecular Biology Laboratory [EMBL]. view more (2007-10-23)
Controlling for size may also prevent cancer
Scientists at Johns Hopkins recently discovered that a chemical chain reaction that controls organ size in animals ranging from insects to humans could mean the difference between normal growth and cancer. view more (2007-09-21)
Study provides hope that some transplant patients could live free of anti-rejection drugs
People with organ transplants, resigned to a lifetime of anti-rejection drugs, may now have reason to hope for a respite, say researchers at Lucile Packard Children's Hospital and the Stanford University School of Medicine. view more (2007-08-21)
Males have adapted to battle with competing sperm
In the context of sexual reproduction, natural selection is generally thought of as a pre-copulation mechanism. We are drawn to features of the human body that tell us our partner is healthy and will provide us a fighting opportunity to carry on our genetic lineage. view more (2007-02-12)
Upgrading donor lung quality to improve availability
By performing simple clinical maneuvers to improve donor lung quality as part of the San Antonio Lung Transplant (SALT) protocol, researchers significantly increased the number of available donor lungs and transplant procedures without compromising recipient pulmonary function, length of hospital stay or survival. view more (2006-09-18)
Scientists show how a neuron gets its shape
Ask a simple question, get a simple answer: When Abraham Lincoln was asked how long a man's legs should be, he absurdly replied, "Long enough to reach the ground." Now, by using a new microscopy technique to watch the growth of individual neurons in the microscopic roundworm Caenorhabditis elegans, Rockefeller University researchers are... view more...

A small leak will sink a great ship
Flowers of higher plants are built in a similar pattern: their outermost whorl is composed of sepals, which protect the young bud, thereafter comes a whorl of often colorful petals attracting insect pollinators, followed by a whorl of stamens with pollen sacks and the innermost whorl holds carpels, which later give rise to the fruit and seeds. view more (2007-06-27)
Delegates From 71 Countries To Attend International Congress Of The Transplantation Society Beginning Sunday
When more than 3,000 surgeons, physicians and scientists from 71 countries converge at the opening ceremonies for the XIX International Congress of the Transplantation Society on Sunday, it will mark the beginning of transplantation`s premiere forum for the presentation of new scientific findings. The congress is considered the field's most... view more... (2002-08-23)
Vitamins C and E support breathing following an operation
Patients who have recently undergone an operation experience less breathing problems after being given a cocktail of vitamins C and E. This is the conclusion reached by researchers from the Leiden University Medical Center following experiments with patients and healthy volunteers. During the first two to three days after a major abdominal... view more... (2002-09-11)
Reconstructing the biology of extinct species: A new approach
An international research team has documented the link between the way an animal moves and the dimensions of an important part of its organ of balance, the three semicircular canals of the inner ear on each side of the skull. view more (2007-06-19)
Convergent evolution of molecules in electric fish
Having a set of extra genes gave fish on separate continents the ability to evolve electric organs, report researchers from The University of Texas at Austin. view more (2006-03-06)
First mouse lung transplants lay groundwork for new ways to prevent transplant rejection in humans
Lung transplants have been performed successfully for more than 20 years in humans but never before in mice - until now. view more (2007-07-12)
Care-seeking behavior associated with 'upper-GI symptoms'
Patients with upper gastrointestinal (GI) complaints visit their general practitioner (GP) more often than patients with other conditions. view more (2009-09-09)
How stem cells are regulated
Researchers from Biotech Research & Innovation Centre (BRIC) at University of Copenhagen have identified a new group of proteins that regulate the function of stem cells. The results are published in the new issue of Cell. view more (2007-02-23)
Early exposure to common weed killer impairs amphibian development
Tadpoles develop deformed hearts and impaired kidneys and digestive systems when exposed to the widely used herbicide atrazine in their early stages of life, according to research by Tufts University biologists. view more (2008-04-16)
Transplants In HIV Patients Should Proceed But Drug Interactions Can Be Concern, Concludes Research At International Congress Of The Transplantation Society
While historically surgeons have been reluctant to transplant patients with the human immunodeficiency virus (HIV), in recent years, some centers have begun to accept patients with well-controlled HIV as candidates for liver or kidney transplantation. Based on results of three studies from the United States and one from France, which collectively... view more... (2002-08-20)
Romance, schmomance - Natural selection continues even after sex
Some breaking news, just in time for Valentine's Day: Researchers have identified something called 'sperm competition' that they think has evolved to ensure a genetic future. In sexual reproduction, natural selection is generally thought of as something that happens prior to - and in fact leads to - the Big Event. view more (2007-02-13)
POOR PREDICTION OF OSTEOPOROSIS AFTER HEART OR LIVER TRANSPLANTATION (pp 325, 342)
The lack of identification of clear risk factors for osteoporotic fractures after organ transplantation reported in this week’s issue of THE LANCET suggests that future post-transplantation treatment should aim to prevent osteoporosis. Osteoporosis and related fractures are a major complication after organ transplantation. Gudrun... view more... (2001-01-31)
