Brain's hippocampus essential for recognizing previously encountered events

The hippocampus, a brain structure known to play a role in memory and spatial navigation, is essential to one's ability to recognize previously encountered events, objects, or people - a phenomenon known as recognition memory - according to new research from the departments of Neurosurgery and Psychology in the Perelman School of Medicine at the University of Pennsylvania.

Scientists propose that Alzheimer's disease should be treated separately

Deciphering the mechanism that underlies the development of Alzheimer's disease in certain families but not in others, researchers at the Hebrew University of Jerusalem's Faculty of Medicine have proposed that the malady is actually a collection of diseases that probably should be treated with a variety of different approaches.

Study provides novel insight into the evolution of hepatitis A virus and how it spreads to humans

Researchers at the University of North Carolina at Chapel Hill are part of an international team led by the University of Bonn, Germany, who have found a link between the origin of hepatitis A virus (HAV) and small mammals.

UCSD researchers suggest that cancer-related mutations common in patients with low blood counts

Patients with unexplained low blood counts and abnormally mutated cells who do not fit the diagnostic criteria for recognized blood cancers should be described as having clonal cytopenias of undetermined significance (CCUS), suggest University of California, San Diego School of Medicine researchers in a recent paper published in the journal Blood.

TUM researchers uncover signaling pathways that play vital role in self-renewal of blood stem cells

Stem cells have two important capabilities: they can develop into a wide range of cell types and simultaneously renew themselves, creating fresh stem cells. Using a model of the blood forming (hematopoietic) system, researchers at the Technical University of Munich have now been able to precisely determine, which signaling pathways play an essential role in the self-renewal of blood stem cells.

Research shows link between absence of RB protein and long-term survival rates in lung cancer patients

November is Lung Cancer Awareness Month, highlighting the number one cause of cancer-related death in North America. While prognosis for the most common form, adenocarcinoma, has remained poor, new research has shown a link between the absence of a specific protein and improved patient outcomes.

Psychoactive drugs can help sedentary people to exercise, suggests Kent endurance expert

Endurance expert suggests drugs could help 'lazy people' exercise In what has been described as 'doping for lazy people' a University of Kent endurance expert has advocated the use of psychoactive drugs to encourage sedentary people to exercise.

Blood stem cell self-renewal dependent on surroundings

Stem cells have two important capabilities: they can develop into a wide range of cell types and simultaneously renew themselves, creating fresh stem cells. Using a model of the blood forming (hematopoietic) system, researchers at the Technical University of Munich (TUM) have now been able to precisely determine, which signaling pathways play an essential role in the self-renewal of blood stem cells. A particularly decisive role in this process is the interactive communication with surrounding tissue cells in the bone marrow.

Misleading symptoms confuse management of older patients with post-HSE relapse

Research shows that teenagers and adults with immune-mediated relapse after herpes simplex encephalitis rarely display the symptoms typically seen in children, delaying the initiation of vital immunotherapy.

Standing one-quarter of the day linked to reduced likelihood of obesity

Standing for at least one-quarter of the day has been linked to lower odds of obesity in a new study led by the American Cancer Society in collaboration with The Cooper Institute, the University of Texas, and the University of Georgia.

Researchers explore effects of hypoglycemia on cardiovascular autonomic control

Past studies have shown an association between strict control of blood sugar and increased mortality. These studies have also suggested that a consequence of this strict control is low blood sugar (called hypoglycemia), which may have adverse effects on the heart.

Researchers find strong associations between hunger and poor health

It may come as a surprise that, even after the Great Recession ended in 2009, almost 50 million people in the United States are food insecure -- that is, they lack access to adequate food because of limited money or other resources. University of Illinois economist Craig Gundersen and University of Kentucky's James Ziliak examined recent research on food insecurity and its association with poor health and offer suggestions, including that doctors screen for hunger.

Lab experiment leads researchers to major red blood cell discovery

A bizarre result of a routine lab experiment has led researchers at the University of Virginia School of Medicine to an unexpected new way to trigger the production of red blood cells. This could represent a significant step forward in the battle against anemia, benefitting people with diabetes, people with kidney disease or cancer, and older people for whom anemia can become a chronic problem.

Good news for patients suffering from dry age-related macular degeneration

Scientists have good news for patients who suffer from currently untreatable dry age-related macular degeneration (dry AMD). In a new study, researchers identified a potential target for future therapies to slow the progression of the blinding condition. Published in Investigative Ophthalmology & Visual Science, the findings indicate that treatments currently used for other conditions could also work for dry AMD.

Older people with age-related muscle loss face greater risk of falls, bone fractures

Older people with an age-related loss of muscle mass and strength may be at greater risk of falling and bone fractures, according to new research led by the University of Southampton.

Deaths from avoidable risk factors: an interview with Dr Ali Mokdad, IHME

The study showed that about thirty percent to maybe half of the leading causes of death in the world are preventable. These are risk factors that you could manage and thus you could prevent a lot of premature deaths.

Federal food policy changes boost healthful food options at smaller urban corner stores

Federal food policy changes led to increased availability of healthy foods at smaller urban corner stores in Baltimore, new Johns Hopkins Bloomberg School of Public Health research suggests. Increases in healthy food were greatest in corner stores and in neighborhoods with a majority of black residents.
