CBSM intervention can alter tumor-promoting processes in women with breast cancer

A team of researchers led by Michael H. Antoni, director of the Center for Psycho-Oncology Research at the University of Miami (UM) has shown that a stress management program tailored to women with breast cancer can alter tumor-promoting processes at the molecular level. The new study recently published in the journal Biological Psychiatry is one of the first to link psychological intervention with genetic expression in cancer patients.

New perspective on why the immune system makes us worse while trying to make us well

A new article in The Quarterly Review of Biology helps explain why the immune system often makes us worse while trying to make us well.

New drug makes chemotherapy more effective in treating acute myeloid leukemia

Doctors at Washington University School of Medicine in St. Louis have shown that a new drug makes chemotherapy more effective in treating acute myeloid leukemia, a cancer of the white blood cells. Instead of attacking these cells directly, the drug helps drive them out of the bone marrow and into the bloodstream, where they are more vulnerable to chemotherapy.

New three-step process for DMD newborn screening

Investigators at Nationwide Children's Hospital, working with the DNA Sequencing Core Facility at the University of Utah, have developed an approach to newborn screening (NBS) for the life-threatening genetic disorder, Duchenne muscular dystrophy (DMD) and potentially other muscular dystrophies.

Gilenya - pill for relapsing-remitting multiple sclerosis recommended by NICE

The National Institute for Health and Clinical Excellence (Nice) issued new draft guidance recommending fingolimod (brand name Gilenya) on the NHS for some patients with a form of MS. The new drug can help reduce the number of relapses in adults with highly active relapsing-remitting multiple sclerosis (RRMS), which is characterized by periods when symptoms worsen and then improve.

Results from AspenBio Pharma's AppyScore trial on appendicitis to be presented at SAEM meeting

The results from AspenBio Pharma's 503-patient pilot study of AppyScore will be presented from the podium the upcoming West Region meeting of the Society for Academic Emergency Medicine (SAEM) being held in Las Vegas, March 16-17.

Addition of inflammatory biomarkers to clinical variables improve mortality prediction in COPD

The addition of changes in inflammatory biomarkers to established clinical variables improves the prediction of mortality in patients with chronic obstructive pulmonary disease (COPD), according to a new study.

CUMC scientists develop a way to recreate personalized immune mouse

Columbia University Medical Center (CUMC) scientists have developed a way to recreate an individual's immune system in a mouse. The "personalized immune mouse" offers researchers an unprecedented tool for individualized analysis of abnormalities that contribute to type 1 diabetes and other autoimmune diseases, starting at the onset of disease.

Study addresses how human body controls gamma-herpesviruses

New research from the Trudeau Institute addresses how the human body controls gamma-herpesviruses, a class of viruses thought to cause a variety of cancers. The study, carried out in the laboratory of Dr. Marcia Blackman, awaits publication in The Journal of Immunology.

New inexpensive medical sensor may simplify diagnosis of diseases

An inexpensive new medical sensor has the potential to simplify the diagnosis of diseases ranging from life-threatening immune deficiencies to the common cold, according to its inventors at the Stanford University School of Medicine.

A novel approach to treating rheumatoid arthritis

Rheumatoid arthritis is a crippling disease and is caused when the body's own immune system attacks the joints and leads to chronic pain and inflammation. A team from Newcastle University funded by Arthritis Research UK have discovered an approach which could effectively prevents white blood cells from reaching the joints and causing more damage.

Europe conference to discuss on new HIV indicator diseases

Today, heterosexuals in Europe are at particular risk of carrying HIV for so long that they remain undiagnosed until their immune system starts to fail and they become ill. An international study under the leadership of the HIV in Europe initiative has now revealed that a number of diseases, including herpes zoster and certain forms of cancer, should be on the list of indicators for having HIV - and thus serve to prompt health care professionals to suggest an HIV-test to their patients.

First study to focus on platelet genetics in African Americans

Researchers, led by scientists from Johns Hopkins, have found five previously unknown gene mutations believed to be associated with elevated blood platelet counts in African-Americans, findings they say could someday lead to the development of new drugs to help prevent coronary artery disease.

New HS44 molecule inhibits lung metastasis

One type of white blood cell, the Natural Killer T Cells, fights against infections and tumours by freeing cytokine proteins which activate the body's immune response and destroy infected or malignant cells. To do so they must receive an activation signal. Specific receptors located on their surface act as switches: they activate the lymphocyte in presence of an antigen, a molecule which triggers alarm signals.

Loss of STAT1 transcription factor causes breast cancer development

Breast cancer represents about a fifth of all cancers diagnosed in women. The reasons for the rapid progression of the disease remain relatively poorly understood but recent work in the group of Veronika Sexl at the University of Veterinary Medicine, Vienna has pointed the finger strongly at loss or inactivation of the transcription factor STAT1.

NKT cells may reduce monocytes accumulation, prevent lung injury in severe flu

While some scientists report engineering a super virulent strain of the H5N1 influenza virus, which could potentially wipe out a significant percentage of the human population, another group of researchers from the United Kingdom now reports a discovery that may one day help mitigate the deadly effects of all flu strains.

Study identifies new processes that lead to development of novel cell implicated in allergies

A collaboration between scientists in Trinity College Dublin and the United Kingdom has identified new processes that lead to the development of a novel cell implicated in allergies. The discovery has the potential for new strategies to treat asthma and other allergic diseases.

Study evaluates how environmental triggers might alter epigenetics of CFS

A University of Toronto Scarborough (UTSC) researcher is examining how environmental triggers might alter gene function in people with Chronic Fatigue Syndrome. The research could lead to better insights into the disease and eventually to new treatments.

Nicotine can contribute to atherosclerosis

Cigarette smoke has long been considered the main risk factor for heart disease. But new research from Brown University in Providence, R.I., shows that nicotine itself, a component of cigarette smoke, can contribute to the disease process by changing cell structure in a way that promotes migration and invasion of the smooth muscle cells that line blood vessels.

Scientists identify specific mechanisms by which vitamin D inhibits inflammation

Researchers at National Jewish Health have discovered specific molecular and signaling events by which vitamin D inhibits inflammation. In their experiments, they showed that low levels of Vitamin D, comparable to levels found in millions of people, failed to inhibit the inflammatory cascade, while levels considered adequate did inhibit inflammatory signaling.
