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)
Tracking membranes of rupturing blood cells sheds light on malaria infection
By specially tagging the outer and inner membranes of red blood cells infected with the malaria parasite and tracking the cellular changes that precede the cell bursting event that disperses parasites to other blood cells, a group of researchers has deepened our understanding of how the malaria pathogen destroys the cells in which it resides. view more (2005-09-22)
Researchers discover how malaria parasite disperses from red blood cells
Researchers at the National Institute of Child Health and Human Development have determined the sequence in which the malaria parasite disperses from the red blood cells it infects. view more (2005-09-20)
When Good DNA Goes Bad: Backward DNA leads to DNA breaks associated with leukemia, study finds
When otherwise normal DNA adopts an unusual shape called Z-DNA, it can lead to the kind of genetic instability associated with cancers such as leukemia and lymphoma. view more (2006-02-13)
A new metal detector to study human disease
Zinc may be a familiar dietary supplement to millions of health-conscious people, but it remains a mystery metal to scientists who study zinc's role in Alzheimer's disease, stroke and other health problems. view more (2006-03-22)
Human Genetic Research: House Of Lords Debate
As the second main item of business on Tuesday 15 January (starting between about 5pm and 6pm), the House of Lords is to debate the Science and Technology Committee's recent report Human Genetic Databases: challenges and opportunities together with the Government's response. The debate will be opened by Lord Oxburgh (Ron Oxburgh, the former Rector... view more... (2002-01-09)
Yale researchers make cell biology quantitative
Yale researchers have reported a method to count the absolute number of individual protein molecules inside a living cell, and to measure accurately where they are located, two basic hurdles for studying biology quantitatively. view more (2005-10-20)
Scientists discover how gold eases pain of arthritis
Scientists at Duke University Medical Center may have solved the mystery surrounding the healing properties of gold - a discovery they say may renew interest in gold salts as a treatment for rheumatoid arthritis and other inflammatory diseases. view more (2007-10-23)
Enzyme action creates protein linked to Alzheimer's disease
Researchers at UT Southwestern Medical Center have defined a key step in the production of beta-amyloid, a short protein that is thought to be responsible for the development of Alzheimer's disease. view more (2005-08-15)
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)
Man-made prostate created by women
In a giant step towards understanding prostate disease, Melbourne scientists have grown a human prostate from embryonic stem cells. view more (2006-02-23)
Researchers identify new way the malaria parasite and red blood cells interact
Virginia Commonwealth University Life Sciences researchers have discovered a new mechanism the malaria parasite uses to enter human red blood cells, which could lead to the development of a vaccine cocktail to fight the mosquito-borne disease. view more (2009-03-11)
Over-the-Counter Arthritis Drug Glucosamine Might Also Help Against MS
Glucosamine, the over-the counter natural product that has been touted to help with joint and cartilage problems associated with arthritis, may also provide some relief to individuals with multiple sclerosis (MS), a degenerative, nervous system disease with no known cure. view more (2005-11-29)
Old mystery solved, revealing origin of regulatory T cells that 'police' and protect the body
More than 150 years after the discovery of Hassall's corpuscles in 1849, the function of these round blobs of cells in the human thymus gland has now been explained. The answer, in turn, ends an intense hunt for the origin of regulatory T cells that has been under way for years. view more (2005-10-13)
Similar stem cells in insect and human gut
Scientists at the Carnegie Institution's Department of Embryology have found that adult fruitflies have the same stem cells controlling cell regulation in their gut as humans do. view more (2005-12-08)
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)
Stress significantly hastens progression of Alzheimer's disease
Stress hormones appear to rapidly exacerbate the formation of brain lesions that are the hallmarks of Alzheimer's disease, according to researchers at UC Irvine. view more (2006-08-30)
