Researchers identify new leprosy bacterium
A new species of bacterium that causes leprosy has been identified through intensive genetic analysis of a pair of lethal infections, a research team reports in the December issue of the American Journal of Clinical Pathology.   view more (2008-11-25)

Researchers aim to over-stress already taxed mantle cell lymphoma cells
Cancer cells are already stressed by the fast pace they require to grow and spread and scientists believe a little more stress just may kill them.   view more (2008-11-11)

MU Study Identifies Patient Strategies for Managing Symptoms of Lymphedema
An estimated 2 million women in the United States are at risk of developing lymphedema, a condition that involves the chronic and abnormal swelling of the arm, chest, neck and/or back, as a complication of breast cancer treatment.   view more (2008-10-30)

New data examine stents and bypass surgery in patients with 3VD and LMD
Newly reported data presented at the 20th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, sponsored by the Cardiovascular Research Foundation (CRF) from the SYNTAX clinical trial (SYNergy Between PCI With TAXUS and Cardiac Surgery) reveal similar safety and efficacy... view more (2008-10-15)

Hodgkin lymphoma -- new characteristics discovered
Researchers are still discovering new characteristics of Hodgkin lymphoma, a common form of cancer of the lymphatic system. The malignant cells are derived from white blood cells (B cells), but have lost a considerable part of the B cell-specific gene expression pattern.    view more (2008-10-09)

Worm genome offers clues to evolution of parasitism
The genome of a humble worm that dines on the microbial organisms covering the carcasses of dead beetles may provide clues to the evolution of parasitic worms, including those that infect humans, say scientists at Washington University School of Medicine in St. Louis and the Max-Planck Institute... view more (2008-09-24)

Study finds B-vitamin deficiency may cause vascular cognitive impairment
A deficiency of B-vitamins may cause vascular cognitive impairment, according to a new study. Researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University used an experimental model to examine the metabolic, cognitive, and microvascular effects of dietary... view more (2008-09-02)

No more big stink: Scent lures mosquitoes, but humans can't smell it
Mosquito traps that reek like latrines may be no more. A University of California, Davis research team led by chemical ecologist Walter Leal has discovered a low-cost, easy-to-prepare attractant that lures blood-fed mosquitoes without making humans hold their noses.   view more (2008-08-29)

Low cholesterol associated with cancer in diabetics
Low levels of LDL cholesterol as well as high levels are associated with cancer in patients with type 2 diabetes.   view more (2008-08-26)

Groundbreaking research shows DEET's not sweet to mosquitoes
Spray yourself with a DEET-based insect repellent and the mosquitoes will leave you alone. But why? They flee because of their intense dislike for the smell of the chemical repellent and not because DEET jams their sense of smell, report researchers at the University of California, Davis.   view more (2008-08-19)

Slipping through cell walls, nanotubes deliver high-potency punch to cancer tumors in mice
The problem with using a shotgun to kill a housefly is that even if you get the pest, you'll likely do a lot of damage to your home in the process. Hence the value of the more surgical flyswatter.    view more (2008-08-15)

U of M study shows why treatment isn't effective for HIV
University of Minnesota researchers have answered a key question as to why antiretroviral therapy isn't effective in restoring immunity in HIV-infected patients.   view more (2008-08-06)

Researchers grow human blood vessels in mice from adult progenitor cells
For the first time, researchers have successfully grown functional human blood vessels in mice using cells from adult human donors - an important step in developing clinical strategies to grow tissue, researchers report in Circulation Research: Journal of the American Heart Association.   view more (2008-07-21)

Improving understanding of cell behaviour in breast cancer
The invasion and spread of cancer cells to other parts of the body, known as metastasis, is a principal cause of death in patients diagnosed with breast cancer.   view more (2008-07-16)

Certain anticancer agents could be harmful to patients with heart disease
A set of promising new anticancer agents could have unforeseen risks in individuals with heart disease, suggests research at Washington University School of Medicine in St. Louis.   view more (2008-06-24)

Mayo researchers discover how measles virus spreads (in its host)
Measles, one of the most common contagious diseases, has been thought to enter the body through the surface of airways and lungs, like many other major viruses.   view more (2008-06-23)

New paradigm for cell-specific gene delivery
Researchers from Northwestern University and Texas A & M University have discovered a new way to limit gene transfer and expression to specific tissues in animals.   view more (2008-06-23)

Mouse model developed at UT Southwestern mimics hyperglycemia, aids in diabetes research
UT Southwestern Medical Center researchers have genetically engineered a laboratory mouse in which pancreatic beta cells can regenerate after being induced to die. The new animal model's regenerative ability may provide future insights into improved treatments of diabetes, which affects millions of... view more (2008-06-02)

Scientists in Japan design first optical pacemaker for laboratory research
The world's first optical pacemaker is described in an article published today in Optics Express, the Optical Society's open-access journal. A team of scientists at Osaka University in Japan show that powerful, but very short, laser pulses can help control the beating of heart muscle cells.   view more (2008-05-28)

A stem cell type supposed to be crucial for angiogenesis and cancer growth does not exist?
Angiogenesis, the growth of new blood vessels, is a central process in diverse physiological and pathological situations such as healing of wounds and traumas, cardiovascular disorders, inflammatory conditions such as rheumatoid arthritis, and in cancer growth.   view more (2008-04-23)

Survival rates appear lower for scalp and neck melanoma than for other sites
Individuals with melanoma on their scalp or neck appear less likely to survive for five or 10 years than those with melanoma at other sites, according to a report in the April issue of Archives of Dermatology, one of the JAMA/Archives journals.   view more (2008-04-22)

Effective cancer immune therapy through order in the blood vessels
Immune therapies are considered very promising in cancer medicine: Tumor-fighting immune cells are supposed to invade tumor tissue and eliminate cancer cells right there.   view more (2008-04-22)

Fuzzy logic water quality
A fuzzy logic approach to analyzing water quality could help reduce the number of people in the developing world forced to drink polluted and diseased water for survival.   view more (2008-04-18)

Human vascular system in mice
The formation of new blood vessels, or angiogenesis, is an Achilles' heel of tumor growth, because tumors depend on the supply of oxygen and nutrients for survival.   view more (2008-04-15)
