Gulf War illness may have two distinct forms, study says

Researchers at Georgetown University Medical Center say their new work suggests that Gulf War illness may have two distinct forms depending on which brain regions have atrophied. Their study of Gulf War veterans, published online today in PLOS ONE, may help explain why clinicians have consistently encountered veterans with different symptoms and complaints.

Non-invasive odor analysis: A valuable technique for early diagnosis of melanoma

According to new research from the Monell Center and collaborating institutions, odors from human skin cells can be used to identify melanoma, the deadliest form of skin cancer. In addition to detecting a unique odor signature associated with melanoma cells, the researchers also demonstrated that a nanotechnology-based sensor could reliably differentiate melanoma cells from normal skin cells.

African-Americans have much greater decrease in their sense of smell, study finds

The ability to distinguish between odors declines steadily with age, but a new study shows that African-Americans have a much greater decrease in their sense of smell than Caucasians.

Mother's exposure to environmental contaminants associated with vigorous fetal motor activity

A study led by researchers at the Johns Hopkins Bloomberg School of Public Health has for the first time found that a mother's higher exposure to some common environmental contaminants was associated with more frequent and vigorous fetal motor activity.

Johns Hopkins researchers develop experimental vaccine for TB meningitis

A team of Johns Hopkins researchers working with animals has developed a vaccine that prevents the virulent TB bacterium from invading the brain and causing the highly lethal condition TB meningitis, a disease that disproportionately occurs in TB-infected children and in adults with compromised immune system.

CLAAD urges FDA to implement Obama administration's policy on safer opioid medications

The Center for Lawful Access and Abuse Deterrence joined in signing a Citizen Petition filed today urging the Food and Drug Administration to fully implement the Obama administration's policy supporting a market transition to safer opioid medications.

African medicinal plants contain chemicals that may help stop spread of cancer cells

African medicinal plants contain chemicals that may be able to stop the spread of cancer cells. This is the conclusion of researchers following laboratory experiments conducted at Johannes Gutenberg University Mainz (JGU).

Drug used to control Type II diabetes can help repair spinal cords of mice suffering from inherited disease

A drug used to control Type II diabetes can help repair the spinal cords of mice suffering from the inherited disease adrenoleukodystrophy which, untreated, leads eventually to a paralysis, a vegetative state and death.

Wayne researchers analyze lead content in local urban garden, evaluate results of several sampling strategies

The local food movement is gaining traction in cities across America, with urban gardens contributing a healthy source of fresh produce for local citizens as well as providing a social outlet for gardeners and creating open spaces for residents to enjoy.

HSV-1 exploits immune system receptor to boost infectivity and cause disease

Researchers at the University of California, San Diego School of Medicine and colleagues report that the herpes simplex virus type-1 (HSV-1), which affects an estimated 50 to 80 percent of all American adults, exploits an immune system receptor to boost its infectivity and ability to cause disease.

Bringing classroom ventilation may reduce student absences due to illness, say researchers

If you suspect that opening windows to let in fresh air might be good for you, a new study by scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) has confirmed your hunch.

Researchers to develop biodegradable replacement for microplastics found in scores of household products

If you've been on or near the water, you've seen it-the plastic trash that litters oceans, lakes, and streams worldwide. But visible plastic-soda bottles, lighters, flip-flops, combs, rope-may be the least of the problem. Scientists are beginning to realize that what you can't see, tiny bits of polyethylene or polypropylene called "microplastics," likely pose a greater threat to marine ecosystems.

Smoke exposure puts infants with respiratory infections at risk for longer hospital stays

More evidence has surfaced that supports the war on smoking, especially if smokers have an infant in their household. A study published today in the June issue of Annals of Allergy, Asthma & Immunology, the scientific journal of the American College of Allergy, Asthma and Immunology (ACAAI), found that infants with a family history of allergic disease with lower respiratory tract infections, who are exposed to secondhand smoke are at risk for longer hospital stays.

Blocking MHCII action rescues nerve cells from Parkinson's disease mechanisms, researchers find

The same mechanism that lets the immune system mount a massive attack against invading bacteria contributes to the destruction of brain cells as part of Parkinson's disease, according to a study published online today in the Journal of Neuroscience.

Tel Aviv University researchers find protein modification may help control Alzheimer's and epilepsy

In the brain, cell-to-cell communication is dependent on neurotransmitters, chemicals that aid the transfer of information between neurons. Several proteins have the ability to modify the production of these chemicals by either increasing or decreasing their amount, or promoting or preventing their secretion.
