Malaria parasite impairs key immune system cells
Plasmodium, the parasite responsible for malaria, impairs the ability of key cells of the immune system to trigger an efficient immune response. view more (2006-04-12)
Possible new compound for treatment of cerebral malaria
In a paper published online in PLoS Medicine researchers from Marseille describe the effects of a new compound that may be a future treatment for patients with cerebral malaria. view more (2005-08-23)
Small molecule offers big hope against cancer
DCA is an odourless, colourless, inexpensive, relatively non-toxic, small molecule. And researchers at the University of Alberta believe it may soon be used as an effective treatment for many forms of cancer. view more (2007-01-17)
Removing DNA repair gene causes metabolic syndrome
Removing a gene involved in repairing damaged DNA causes mice to develop the metabolic syndrome, researchers at Oregon Health & Science University have discovered. view more (2006-02-09)
New studies show topical glucosamine targets pigment overproduction
Data presented at 2006 American Academy of Dermatology Meeting uses first ever non-invasive imaging system to detect pigment changes, test glucosamine efficacy. view more (2006-03-24)
Stem cell identity in culture may strongly depend on the cellular microenvironment
Identification, isolation and large scale culture of stem cells for potential medical applications is a major challenge in cell biology. view more (2007-04-25)
Novel mechanism for DNA replication discovered
Since the discovery of the structure of DNA by James Watson and Francis Crick in 1953, the paradigm for DNA replication has stated that the DNA itself codes for the appropriate pairings for replication. view more (2005-09-30)
Diabetes complications rooted in faulty cell repair
University of Florida researchers say primitive cells that act like molecular maintenance men-traveling throughout the body to repair damaged blood vessels-become too rigid to move in patients with diabetes, fueling the disease's vascular complications. view more (2006-01-26)
Cord blood cells may widen treatment window for stroke
Researchers at the University of South Florida found that human umbilical cord blood cells administered to rats two days following a stroke greatly curbed the brain's inflammatory response, reducing the size of the stroke and resulting in greatly improved recovery. view more (2005-11-14)
Studies Suggest New Targets for Tuberculosis Treatments
With the hope of designing more effective treatments for tuberculosis (TB), scientists from the U.S. Department of Energy's Brookhaven National Laboratory and collaborating institutions have published the first detailed reports on the biochemistry and structure of a protein-cleaving complex that is essential to the TB bacterium's survival. view more (2006-03-07)
Cell wall of pneumonia bacteria can cause brain and heart damage
Investigators at St. Jude Children's Research Hospital have discovered in mouse models how cell walls from certain pneumonia-causing bacteria can cause fatal heart damage; researchers have also shown how antibiotic therapy can contribute to this damage by increasing the number of cell wall pieces shed by dying bacteria. The team also demonstrated... view more... (2006-10-25)
U of MN researchers use human embryonic stem cells to kill cancer cells
For the first time, stem cell researchers at the University of Minnesota have coaxed human embryonic stem cells to create cancer-killing cells in the laboratory, paving the way for future treatments for various types of cancers (or tumors). view more (2005-10-12)
Damage to sperm DNA affects older men's chances of fathering children
Damage to DNA in sperm is significantly higher in older men than in those who are younger, according to research presented today (Tuesday 21 June 2005) at the 21st annual conference of the European Society of Human Reproduction and Embryology. view more (2005-06-21)
Novel lipoplex nanoparticle to be used in 1st human trial treating advanced solid cancer
The first clinical trial of a biologic nanoparticle designed to give back to cancer patients the tumor-busting gene they have lost is expected to start in September at Georgetown University Medical Center. view more (2005-08-25)
Exercise can protect against skin cancer
While doctors and scientists have long agreed that physical activity has health benefits, Rutgers cancer researcher Allan Conney and his New Jersey colleagues have found that exercise can even protect against skin cancer. view more (2006-05-15)
Tumor cells evade death through autophagy
Autophagy is a cellular process that enables cells to turnover their contents, something that they do frequently. Autophagy is initiated in tumor cells by chemotherapy and radiation, but it is not known if this contributes to tumor cell death or helps tumor cells survive the anti-cancer therapy. view more (2007-01-19)
How to design a cancer-killing virus
One new way to treat individuals with cancer that is being developed is the use of viruses that infect and kill cancer cells while leaving normal cells unharmed. view more (2007-10-26)
Researchers find molecule that inhibits regrowth of spinal nerve cells
A molecule that helps the body's motor nerve cells grow along proper paths during embryonic development also plays a major role in inhibiting spinal-cord neurons from regenerating after injury, researchers at UT Southwestern Medical Center have found. view more (2005-07-12)
The world's oldest bacteria
A research team has for the first time ever discovered DNA from living bacteria that are more than half a million years old. Never before has traces of still living organisms that old been found. view more (2007-08-28)
Marijuana compound may help stop diabetic retinopathy
A compound found in marijuana won't make you high but it may help keep your eyes healthy if you're a diabetic, researchers say. view more (2006-02-28)
