Poor sleep more dangerous for women

Researchers at Duke University Medical Center say they may have figured out why poor sleep does more harm to cardiovascular health in women than in men.

New way to develop tumor vaccines

Researchers at the University of Southern California (USC) have uncovered a new way to develop more effective tumor vaccines by turning off the suppression function of regulatory T cells.

Stress and fear affects cancer's recurrence

After the surgical removal of a malignant tumor, the chance that cancer will re-appear in a different location of the body remains high.

Discovery of potential drug targets for sepsis

"We have identified a key connection of signaling pathways in the cascade of events leading to sepsis. This defines a crucial point where the immune system spirals out of control to cause severe sepsis and where there is an opportunity for therapeutic intervention," says Scripps Research Professor Wolfram Ruf, who led the research with his postdoctoral fellow Frank Niessen.

Scientists devise approach that stops HIV at earliest stage of infection

Their study, which appears this week in the online Early Edition of the Proceedings of the National Academy of Sciences (PNAS), may re-energize attempts to create a preventive/therapeutic vaccine against HIV, say the authors.

Research leading to tools for managing bovine respiratory disease complex

Bovine respiratory disease complex has multiple causes. It's sometimes hard to classify and predict. It also costs the beef industry more than any other disease -- an estimated $690 million in 2006, according to one report.

Nasal vaccine for smallpox protects animals against 77 times the potentially lethal dose of smallpox

Scientists at NanoBio Corporation and the University of Michigan have demonstrated their nasally delivered vaccinia vaccine can protect animals against 77 times the potentially lethal dose of smallpox, and without the safety risks of current vaccines for smallpox.

Nanoemulsion vaccines show increasing promise

A novel technique for vaccinating against a variety of infectious diseases - using an oil-based emulsion placed in the nose, rather than needles - has proved able to produce a strong immune response against smallpox and HIV in two new studies.

Combination vaccine against Ebola and Marburg viruses provides complete protection for monkeys

An experimental, combination vaccine against Ebola and Marburg viruses using virus-like particles (VLPs) provides complete protection against infection in monkeys.

Gene therapy - immune system discovery may lead to effective treatment for glioblastoma multiforme

A new gene therapy approach that attracts and "trains" immune system cells to destroy deadly brain cancer cells also provides long-term immunity, produces no significant adverse effects and -- in the process of destroying the tumor -- promotes the return of normal brain function and behavioral skills, according to a study conducted by researchers at Cedars-Sinai Medical Center's Board of Governors Gene Therapeutics Research Institute.

Biannual mass antibiotic treatment may help reduce contagious eye disease trachoma in Africa

Changing the administration of the antibiotic azithromycin from once to twice a year in villages in Ethiopia substantially reduced eye infections in preschool children caused by chlamydia, which causes the serious, contagious eye disease trachoma, according to a study in the February 20 issue of JAMA.

Potential new strategy for treating lupus

Immune cells that would normally die in healthy people accumulate in bodies of patients who have lupus and contribute to the disease, according to new Saint Louis University research published in the Feb. 15 issue of Immunity.

Stomach flu vaccine possibility

Every year, millions of people are infected with noroviruses - commonly called "stomach flu" - often resulting in up to 72 hours of vomiting and diarrhea.

Probiotics help keep elite athletes fit and well

According to the latest Australian research the immune system of long-distance runners was enhanced by probiotics - dietary supplements containing potentially beneficial bacteria or yeasts.

Prenatal exposure to maternal antibodies linked to autistic behaviors in offspring

New research from the UC Davis M.I.N.D. Institute shows that an interaction between fetal brain cells and maternal antibodies could be linked with the repetitive behavior - also called stereotypies - that is characteristic of autism.

New vaccine for malaria under trial

Trials are underway, funded by the Wellcome Trust, for a new vaccine to combat the most deadly form of malaria.

Resisting lung cancer recurrence - Vaccine booster gives persistent immune response

What if we could prevent cancer recurrence for years after surgery by giving simple recall injections every two or three years? This concept may no longer be a fantasy.

A possible H5N1 vaccine

A vaccine against the most common and deadliest strain of avian flu, H5N1, has been engineered and tested by researchers at the University of Pittsburgh's Center for Vaccine Research and Novavax Inc.

Texas officials studying needle-exchange program

Health officials in Bexar County, Texas, are considering if they should launch the state's first needle-exchange program in an effort to reduce the spread of HIV and other bloodborne diseases, but Bexar County District Attorney Susan Reed has said that she will not hesitate to prosecute anyone who distributes needles before the program is approved, the Los Angeles Times reports (Bustillo, Los Angeles Times, 1/28).

Evolutionary 'battle scars' identify enhanced antiviral activity

Rapid evolution of a protein produced by an immunity gene is associated with increased antiviral activity in humans, a finding that suggests evolutionary biology and virology together can accelerate the discovery of viral-defense mechanisms, according to researchers at Fred Hutchinson Cancer Research Center.
