New advances in Alzheimer's disease research

Advancing age is a major risk factor for Alzheimer's disease and is associated with build- up of the peptide amyloid β in the brain. New research published in BioMed Central's open access journal Fluids and Barriers of the CNS shows that removal of amyloid β from the brain depends on vitamin D and also on an age-related alteration in the production of transporter proteins which move amyloid β in and out of the brain.

AHAF awards 22 new grants to scientists worldwide for innovative vision research

The American Health Assistance Foundation (AHAF), a nonprofit organization with a history of funding cutting-edge research on age-related diseases, announced today that it has awarded 22 new grants totaling nearly $2.2 million to scientists worldwide who are studying glaucoma and macular degeneration. The two conditions are the leading causes of irreversible vision loss and blindness in the U.S.

Cortisol hormone controls bile acid recycling process

Nature sees to it that we do not have "too much choler" in our body. A delicately equilibrated regulation system ensures that there is always exactly the right amount of bile in the gallbladder. When we are hungry, our body releases a hormone called cortisol, which is a glucocorticoid. Hepatic cells receive this hormone signal through their cortisol receptors and respond by filling the gallbladder with bile in preparation of the imminent food intake.

International biologists discover seven new species of mice

After living incognito for millions of years in a remote area of a forested mountain range in the Philippines, seven newfound species of mice owe their recent discovery to DNA evidence and the Florida State University biologist who deciphered it.

Researchers identify cellular origin of malignant glioma

Using a mouse genetic system co-developed by researchers at the University of Oregon and Stanford University, a research team led by UO biologist Hui Zong has isolated the cellular origin for malignant glioma, a deadly human brain cancer.

Final Atlantis space trip may open new era of research into infectious diseases

On July 8, at approximately 11:26 a.m. EDT, the space shuttle Atlantis will streak skyward from the Kennedy Space Center's launch pad 39A, for one last mission. While the STS-135 flight marks the end of the space shuttle's glory days, its final trip may open a new era of research into infectious diseases, thanks to space bound experiments conducted by Dr's. Cheryl Nickerson, and Roy Curtiss III, along with their colleagues at Arizona State University's Biodesign Institute.

Researchers use AFM to characterize ovarian cell structure for cancer diagnosis

Using ovarian surface epithelial cells from mice, researchers from Virginia Tech have released findings from a study that they believe will help in cancer risk assessment, cancer diagnosis, and treatment efficiency in a technical journal: Nanomedicine.

Levels of urinary eosinophil protein-X may predict future atopy in asymptomatic children

The signs of atopy may be present long before symptoms begin, even in month-old babies, according to a new research study from Denmark. The study found that the level of urinary eosinophil protein-X (u-EPX), a marker of inflammatory cells, in newborn babies was linked to higher risk of allergic sensitization, nasal eosinophilia and eczema at six years.

Experiment to protect astronauts from bone loss during space travel

Astronauts lose a significant amount of bone mass during space travel and with long duration flights there is concern that this bone loss could lead to an increased risk of fractures.

Study finds link between genetic variation and cetuximab rectal cancer therapy

team of researchers led by Keck School of Medicine of the University of Southern California (USC) oncologist Heinz-Josef Lenz, M.D., has identified a genetic marker that may predict which patients with rectal cancer can be cured by certain chemotherapies when combined with surgery.

Scientists identify molecular mechanism behind alcohol-induced blackouts

A person who drinks too much alcohol may be able to perform complicated tasks, such as dancing, carrying on a conversation or even driving a car, but later have no memory of those escapades. These periods of amnesia, commonly known as "blackouts," can last from a few minutes to several hours.
