Jefferson researcher’s results show promise for metastatic eye melanoma

But now, by simultaneously revving up the immune system and choking off the tumor’s oxygen supply, oncologists at Jefferson Medical College and the Kimmel Cancer Center at Thomas Jefferson University in Philadelphia may have found a better way to battle this deadly cancer.

Scientists have uncovered a new method the immune system uses to label foreign invaders as targets to be attacked

Researchers showed that the immune system can brand foreign proteins by chemically modifying their structure, and that these modifications increased the chances that cells known as lymphocytes would recognize the trespassers and attack them.

Drugs that block the enzyme Odc prevent the onset of cancers

The drug DFMO prevents cancer in laboratory models of lymphoma but fails to kill existing cancerous cells that have lost the ability to self-destruct, according to investigators at St. Jude Children's Research Hospital.

Intralesional immunotherapy for common warts is effective and safe

Injection of skin test antigens (preparations used in skin tests for immunity) into warts appears to stimulate the immune system and successfully treat the injected wart and also helps to treat distant non-injected warts, according to a study in the May issue of Archives of Dermatology.

Disabling gene defuses rheumatoid arthritis in mice

Scientists studying mice have identified a gene that allows immune cells known as neutrophils to protect themselves from the inflammatory chemicals they secrete.

Moderate recreational and work-related physical activity may reduce the risk of ovarian cancer

While the benefits of physical activity in reducing colon and breast cancer are well established, results of studies on exercise and ovarian cancer have been inconclusive. Because ovarian cancer has such a poor prognosis, it is even more important to identify modifiable lifestyle factors that could prevent it.

Vaccine candidate to treat nicotine addiction shows promise

Cytos Biotechnology AG has announced that its vaccine candidate CYT002-NicQb to treat nicotine addiction has achieved proof of efficacy.

Alcohol consumption increases movement of S. pneumoniae toward the lungs

Streptococcus pneumoniae is a bacterium that can infect the upper respiratory tract and cause pneumonia, as well as infections in other parts of the body such as the bloodstream (bacteremia), lining of the brain and spinal cord (meningitis), bones (osteomyelitis), joints (arthritis), ears (otitis media) and sinuses (sinusitis).

Two-sided coating could breathe life into medical implants

By mimicking an adhesive protein secreted by mussels and a polymer that repels cells and proteins, researchers at Northwestern University have designed a versatile new two-sided coating that could breathe life into medical implants.

Humans more prone to cancer than chimpanzees

Chimpanzees and humans share a common ancestor, and even today 99 percent of the two species' DNA is identical. But since the paths of man and chimp diverged 5 million years ago, that one percent of genetic difference appears to have changed humans in an unexpected way: It could have made people more prone to cancer.

Miserable mumps makes a comeback

There is concern in the UK at the growing number of outbreaks of mumps among children and young people.

Insulin - possible vaccine against type 1 diabetes

It has taken scientists at the University of Miami's Diabetes Research Institute eight long years of painstaking research, but they believe they have finally pinned down Insulin, the hormone most closely linked to diabetes, to be the cause of the inherited form of the blood sugar disease.

New predictor for blood transplant success

The success of blood stem cell transplants used to treat diseases such as leukemia, Hodgkin’s lymphoma and aplastic anemia may soon become more predictable, thanks to a discovery made by researchers at the University of British Columbia.

Broken bones may reduce risk of ovarian cancer

The pain and suffering of a broken bone may yield an unexpected benefit – a reduced risk of ovarian cancer.

Discovery reveals how stem cells can be used to help repair acute spinal cord damage

A treatment derived from human embryonic stem cells improves mobility in rats with spinal cord injuries, providing the first physical evidence that the therapeutic use of these cells can help restore motor skills lost from acute spinal cord tissue damage.

Vaccine against Alzheimer's disease may still be on the cards

A new, but modified, trial of an Alzheimer's vaccine has begun in the U.S. despite an earlier one being abandoned in 2002 due to safety concerns.

Research offers new molecular approaches to therapies for the most deadly cancers

Researchers at Wake Forest University Baptist Medical Center have found promising new molecular targets and treatment approaches for some of the most malignant brain tumors.

Laboratory model of immune system overcomes ethical constraints on studies of hematopoietic stem cells in humans

Scientists at St. Jude Children’s Research Hospital have joined with colleagues at several other institutions to develop a laboratory model of the human immune system. This model will allow scientists to study ways for improving the results of hematopoietic stem cell (HSC) transplantation without putting patients at risk.

Researchers test vaccine to prevent dangerous Staphylococcal infections

Vanderbilt University Medical Center infectious diseases researchers are launching a trial for a new vaccine against Staphylococcus aureus. The vaccine, if proven effective, could help curb the growing threat of methicillin-resistant Staphylococcus aureus (MRSA), an emerging organism rapidly spreading through close personal contact.

Blood tests show autistic children have abnormal immune-system responses

Scientists in the U.S. have discovered that children with autism have abnormal immune-system responses and are optimistic that their findings could be used to develop a blood test to screen for the behavioural disorder.
