Scientists discover specific immune system T cells that trigger destruction of type 1 diabetes

Researchers at the La Jolla Institute for Allergy & Immunology have proven - for the first time in human tissues -- the specific immune system T cells which trigger the destruction of type 1 diabetes in the pancreas. The finding is an important advance that verifies in humans several important disease characteristics shown in mouse studies and provides a key focal point for interrupting the disease process.

Cryo-electron microscopy can visualize structures within viruses

Since the discovery of the microscope, scientists have tried to visualize smaller and smaller structures to provide insights into the inner workings of human cells, bacteria and viruses. Now, researchers at the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), part of the National Institutes of Health, have developed a new way to see structures within viruses that were not clearly seen before.

AICAR might protect against heat stress in MH-susceptible individuals

Malignant hyperthermia (MH) is a life-threatening genetic muscle disorder, most commonly triggered in those at risk by certain types of drugs used during anesthesia. Heat stroke, on the other hand, most commonly occurs in individuals in response to physical exertion in hot/humid environments. While their common triggers may differ, the signs associated with MH and heat stroke are remarkably similar - uncontrolled muscle contractions, dangerous increases in body temperature, and muscle breakdown leading to the release of toxins in the blood which may cause cardiac arrhythmias and death. Immediate treatment for these conditions is crucial.

Non-toxin vaccine shows promise against lethal anthrax infection

Vaccination with the anthrax capsule-a naturally occurring component of the bacterium that causes the disease-protected monkeys from lethal anthrax infection, according to U.S. Army scientists. The study, which appears in the Jan. 20th print edition of the journal VACCINE, represents the first successful use of a non-toxin vaccine to protect monkeys from the disease.

Gut bacteria may determine outcome of heart attack

New research published online in the FASEB Journal suggests that the types and levels of bacteria in the intestines may be used to predict a person's likelihood of having a heart attack, and that manipulating these organisms may help reduce heart attack risk.

New lab test quickly identifies bacterium responsible for staph infections

Researchers from the Georgia Institute of Technology and the Centers for Disease Control and Prevention (CDC) have developed a new laboratory test that can rapidly identify the bacterium responsible for staph infections. This new test takes advantage of unique isotopic labeling combined with specific bacteriophage amplification to rapidly identify Staphylococcus aureus.

Researchers identify human receptor that can taste fat

Why do we like fatty foods so much? We can blame our taste buds. Our tongues apparently recognize and have an affinity for fat, according to researchers at Washington University School of Medicine in St. Louis. They have found that variations in a gene can make people more or less sensitive to the taste of fat.

Study shows how Notch gene and PRC2 protein complex work together to cause T-ALL

A new study published in the journal Nature Medicine by NYU Cancer Institute researchers, shows how the cancer causing gene Notch, in combination with a mutated Polycomb Repressive Complex 2 (PRC2) protein complex, work together to cause T- cell acute lymphoblastic leukemia.

Lack of iron early in life can affect brain's physical structure

Iron is a popular topic in health news. Doctors prescribe it for medical reasons, and it's available over the counter as a dietary supplement. And while it's known that too little iron can result in cognitive problems, it's also known that too much promotes neurodegenerative diseases. Now, researchers at UCLA have found that in addition to causing cognitive problems, a lack of iron early in life can affect the brain's physical structure as well.

Grapes offer dramatic protection against age-related macular degeneration

Can eating grapes slow or help prevent the onset of age-related macular degeneration (AMD), a debilitating condition affecting millions of elderly people worldwide? Results from a new study published in Free Radical Biology and Medicine suggest this might be the case. The antioxidant actions of grapes are believed to be responsible for these protective effects.

Female fish choose well fed males over undernourished ones: Study

At least in some species being well fed as a kid makes a male more attractive to the opposite sex. Researchers from the Australian National University (ANU) have discovered female mosquitofish (Gambusia holbrooki) prefer males with a strong nutritional upbringing. The preference is there even when the males are otherwise identical to previously undernourished fish. These mosquitofish were introduced to Australia in an attempt to control mosquitoes.

Low-glycemic-load diet reduces C-reactive protein associated with chronic disease

Among overweight and obese adults, a diet rich in slowly digested carbohydrates, such as whole grains, legumes and other high-fiber foods, significantly reduces markers of inflammation associated with chronic disease, according to a new study by Fred Hutchinson Cancer Research Center.
