Protein DNA repair complex key to avoiding DNA repair mistakes

As the body creates antibodies to fight invaders, a three-protein DNA repair complex called MRN is crucial for a normal gene-shuffling process to proceed properly, University of Michigan research shows.

Discovery of potential candidate protein for cancer vaccines

Researchers at the University of Pittsburgh School of Medicine have learned that some healthy people naturally developed an immune response against a protein that is made in excess levels in many cancers, including breast, lung, and head and neck cancers. The finding suggests that a vaccine against the protein might prevent malignancies in high-risk individuals.

Viral RNA linked to human immune response

In its fight against an intruding virus, an enzyme in our immune system may sense certain types of viral RNA pairs, according to scientists.

Regional nerve block anesthesia improve recovery, outcomes

When planning for surgery, patients too often don't consider the kind of anesthesia they will receive. In fact, the choice of anesthesia can improve recovery, even outcomes.

New method selectively kills metastatic melanoma

An international team of researchers has identified a new method for selectively killing metastatic melanoma cells, which may lead to new areas for drug development in melanoma – a cancer that is highly resistant to current treatment strategies.

The extremes of BMI a cause for concern in liver transplantation

A recent study by doctors at the University of Washington explained that patients who are significantly underweight or very severely obese prior to liver transplantation are at increased risk of death following transplantation surgery.

New research helps explain why treated genital herpes sores boost risk of HIV infection

New research helps explain why infection with herpes simplex virus-2 (HSV-2), which causes genital herpes, increases the risk for HIV infection even after successful treatment heals the genital skin sores and breaks that often result from HSV-2.

Breastfeeding can save 1.3 million children annually, WHO says

About 1.3 million children's lives could be saved each year by teaching new mothers how to breastfeed, but many women do not receive help and stop trying, the WHO said on Friday ahead of the start of World Breastfeeding Week, which runs from August 1 through August 7, Reuters reports.

Research may bring powerful new test for inflammatory lung diseases

Chronic inflammatory lung diseases like chronic bronchitis and emphysema are a major global health problem, and the fourth leading cause of death and disability in developed countries, with smoking accounting for 90% of the risk for developing them.

Medicago announces positive results for H1N1 pandemic vaccine candidate

Medicago today announced that it has achieved additional positive results with its vaccine candidate for the Influenza A (H1N1) virus, also known as Swine flu. Results showed that a single dose of 5 micrograms induced a positive immune response against a new emerging strain of this virus in 100% of vaccinated animals.

Research suggests that zinc activates a key protein on T cells needed to fight infections

Everyone knows that vitamins "from A to zinc" are important for good health. Now, a new research study in the August 2009 print issue of the Journal of Leukocyte Biology suggests that zinc may be pointing the way to new therapeutic targets for fighting infections.

Virus may play role in causing some cases of squamous cell carcinoma

A virus discovered last year in a rare form of skin cancer has also been found in people with the second most common form of skin cancer among Americans, according to researchers at the Ohio State University Comprehensive Cancer Center - James Cancer Hospital and Solove Research Institute.

UV radiation from sunlight may trigger certain autoimmune diseases in women

Ultraviolet (UV) radiation from sunlight may be associated with the development of certain autoimmune diseases, particularly in women, according to a study by researchers at the National Institute of Environmental Health Sciences (NIEHS), part of the National Institutes of Health.

Protein level may predict severe osteoarthritis

Osteoarthritis (OA), the most common joint disorder throughout the world and a leading cause of disability, is characterized by pain, impaired joint mobility, reduction of muscular strength and loss of joint function. Unlike most other common diseases, little is known about its origins, and factors predicting a severe disease course have not been identified.

Immune responses to flu vaccine are diminished in lupus patients

Patients with the autoimmune disease systemic lupus erythematosus (SLE) have an increased risk of infection, due to both disturbances in their immune responses and treatment with immunosuppressive drugs.

Malaria vaccine in the pipeline

Australian scientists have developed the first genetically-engineered malaria vaccine and the vaccine will be trialled in humans early next year.

World's first genetically-modified strain of malaria parasite

Walter and Eliza Hall Institute scientists have created a weakened strain of the malaria parasite that will be used as a live vaccine against the disease. The vaccine, developed in collaboration with researchers from the US, Japan and Canada, will be trialled in humans from early next year.
