Study finds 'grid cells' that help brain map locations outside hippocampus

"Grid cells," which help the brain map locations, have been found for the first time outside of the hippocampus in the rat brain, according to new research from the Norwegian University of Science and Technology (NTNU). The finding should help further our understanding of how the brain generates the internal maps that help us remember where we have been and how to get to where we want to go.

Epitherix identifies potent and selective multiple chemical scaffolds against colorectal carcinoma

Epitherix, LLC, a privately held company focused on the discovery and development of novel Wnt pathway small molecule inhibitors for epithelial and leukemic cancers, today announced that it has identified multiple chemical scaffolds that are potent and selective against colorectal carcinoma. "We're very encouraged by our in vitro and in vivo data, especially considering the difficulty in drugging this pathway to date," said Dr. Osman Kibar, CEO of Epitherix.

Brain-wave pattern study may lead to techniques for enhancing sleep spindles

People who have trouble sleeping in noisy environments often resort to strategies like earplugs or noise-cancelling headphones that muffle the sound, but a new study from investigators at Massachusetts General Hospital (MGH) may lead to ways to block disturbing sounds within the brain. In their report in the August 10 issue of Current Biology, the team reports finding a brain-wave pattern, reflecting activity of a key structure, that predicts the ease at which sleep can be disrupted by noise.

Mild sleep restriction for several nights can affect cognitive tasks: Research

Many people are sleep restricted, either because they have to or because they choose to be, she says. "Instead of going to bed when they are tired, like they should, people watch TV and want to have an active social life," she says. "People count on catching up on their sleep on the weekends, but it may not be enough."

Study on ethnic disparities in pediatric asthma in Latino and non-Latino children

A new study by researchers at the Bradley Hasbro Children's Research Center and the University of Puerto Rico may help explain some of the well-documented ethnic disparities in pediatric asthma.

Ratios between males and females affect human longevity: Study

"Love stinks!" the J. Geils band told the world in 1980, and while you can certainly argue whether or not this tender and ineffable spirit of affection has a downside, working hard to find it does. It may even shorten your life.

New scaffold supports growth, integration of stem cell-derived cardiac muscle cells

These days people usually don't die from a heart attack. But the damage to heart muscle is irreversible, and most patients eventually succumb to congestive heart failure, the most common cause of death in developed countries.Stem cells now offer hope for achieving what the body can't do: mending broken hearts. Engineers and physicians at the University of Washington have built a scaffold that supports the growth and integration of stem cell-derived cardiac muscle cells. A description of the scaffold, which supports the growth of cardiac cells in the lab and encourages blood vessel growth in living animals, is published this week in the Proceedings of the National Academy of Sciences.

New insight into protein transport mechanism can improve chemotherapy treatments

A new study conducted in the department of Biochemistry and Molecular Biology at Tel Aviv University (TAU) elucidates the way in which toxic, yet essential, copper ions enter human cells. As a chemotherapy drug presumably enters the cells in a similar manner, the results of this study pave the way for the development of improved chemotherapeutic drugs. The groundbreaking work was published in the leading American scientific journal PNAS (Proceedings of the National Academy of Sciences).

Research on role of ADAM12 gene in breast cancer

A microscopic gene may play a gigantic role when it comes to cancerous tissue in the human body, according to one Kansas State University research team.The team is investigating mutation within the ADAM12 gene of the A Disintegrin and Metalloprotease family, or ADAM family, and its role in breast cancer."We want to know whether ADAM12 is a good guy or a bad guy in breast cancer," said Anna Zolkiewska, associate professor of biochemistry and research team leader.

Sound sleepers show distinct pattern of spontaneous brain rhythms: Research

Ever wonder why some people can sleep through just about anything, while others get startled awake at each and every bump in the night? A new report in the August 10th issue of Current Biology, a Cell Press publication, offers some insight: sound sleepers show a distinct pattern of spontaneous brain rhythms.We found that by measuring brain waves during sleep, we could learn a lot about how well a person's brain can block the negative effects of sounds; the more sleep spindles your brain produces, the more likely you'll stay asleep, even when confronted with noise, said Jeffrey Ellenbogen of Harvard Medical School.

Scientist to research on molecular machinery of breast cancer

Someone in the world is diagnosed with breast cancer every 23 seconds. It is the leading cause of cancer death worldwide among women and approximately 456,000 die from the disease each year. At The University of Texas Health Science Center at Houston (UTHealth), a scientist is taking aim at the molecular machinery behind this disease.

Scientists discover role of Mnk enzyme in prostate cancer development

A kinase is a type of enzyme the body uses to regulate the functions of the proteins required for cell growth and maintenance, and researchers have discovered that one in particular plays a key role in developing prostate cancer. "It's known as Mnk, and although it appears not to be essential for normal cell maintenance, it's important for cancer growth" said Dr. Luc Furic, a postdoctoral researcher working with Dr. Nahum Sonenberg at McGill University's Goodman Cancer Research Centre and Department of Biochemistry.

Study suggests reimbursements can address inappropriate antibiotic usage

Antibiotic use appears to have increased among older adults whose prescription drug coverage improved as a result of enrolling in Medicare Part D, with the largest increases for broad-spectrum, newer and more expensive drugs, according to a report in the August 9/23 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

Scientists work towards creating a vaccine for Parkinson's disease

Nina Brown, 68, and millions of others with a debilitating neurological condition called Parkinson's disease are counting on researchers for a cure. At The University of Texas Health Science Center at Houston (UTHealth), protein chemists are working to develop a therapeutic vaccine.

UCLA study identifies neurocognitive pathways involved in inflammatory responses to acute social stress

Everyone experiences social stress, whether it is nervousness over a job interview, difficulty meeting people at parties, or angst over giving a speech. In a new report, UCLA researchers have discovered that how your brain responds to social stressors can influence the body's immune system in ways that may negatively affect health.

Vena cava blood clot filters may cause potential life-threatening complications: Study

Two specific types of vena cava filters, devices used to prevent blood clots from reaching the lungs, appear to have evidence of fracturing inside the body, with some fractured fragments traveling to the heart and causing potentially life-threatening complications, according to a report posted online today that will appear in the November 8 print issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

Scientist develops nano-methods to destroy tumors with fewer side effects

Though a valuable weapon against cancerous tumors, radiation therapy often harms healthy tissue as it tries to kill malignant cells. Now, Prof. Israel Gannot of Tel Aviv University's Department of Biomedical Engineering is developing a new way to destroy tumors with fewer side effects and minimal damage to surrounding tissue.

Increase of alcohol taxes can reduce alcohol-related deaths

Adjusting the alcohol tax in Florida to account for inflation since 1983 would prevent 600 to 800 deaths each year in that state from diseases caused by chronic heavy alcohol use, according to a new study from the University of Florida. The Florida legislature last increased alcohol taxes in 1983.
