Rice and Penn researchers create silicon construct with complex network of blood vessels

Using sugar, silicone and a 3-D printer, a team of bioengineers at Rice University and surgeons at the University of Pennsylvania have created an implant with an intricate network of blood vessels that points toward a future of growing replacement tissues and organs for transplantation.

Study shows post-stroke loss of speech can be recovered

After a debate that has lasted more than 130 years, researchers at Georgetown University Medical Center have found that loss of speech from a stroke in the left hemisphere of the brain can be recovered on the back, right side of the brain. This contradicts recent notions that the right hemisphere interferes with recovery.

Estradiol fluctuation may enhance emotional sensitivity to psychosocial stress during menopausal transition

If you're feeling a little blue during the transition to menopause, there's good reason, according to a new study being reported online today in Menopause, the journal of The North American Menopause Society (NAMS). The study from the Department of Psychiatry at the University of North Carolina at Chapel Hill suggests that the estradiol (a form of estrogen) fluctuation that is common during the menopausal transition may enhance emotional sensitivity to psychosocial stress.

Oxford professor wins Heinrich Wieland Prize for pioneering method that helps control nerve cells with light

Gero Miesenböck was the first to insert a light-controlled on/off switch into brain cells. His pioneering method allows scientists to switch nerve cells on and off selectively and observe how the behaviour of, for example, fruit flies or mice changes as a result. In this way, researchers can learn in a step-by-step process what behaviour the studied brain circuits control and what goes awry in disease. For his method, hailed as a "breakthrough of the decade," Professor Gero Miesenböck of the University of Oxford will receive the 100,000-euro Heinrich Wieland Prize of the Boehringer Ingelheim Foundation in Munich on November 6, 2015.

New Swedish study questions treatment of female infertility with stem cell therapy

It has been claimed that a treatment for female infertility will be available by stem cell therapy. But a new study by Swedish researchers from the University of Gothenburg and Karolinska Institutet published in Nature Medicine questions whether new egg cells can be produced using stem cells.

Scientists show how specialized cells help each other survive under stress

A team led by scientists from the Florida campus of The Scripps Research Institute and the University of Pittsburgh has shown for the first time how one set of specialized cells survives under stress by manipulating the behavior of key immune system cells.

Millions more bird species killed by West Nile virus than previously thought

West Nile virus is killing millions more birds and affecting many more bird species than previously thought, according to new research from a multi-university team of researchers.

International research project examines effectiveness of tried and tested medicines for different diseases

The Medical University of Vienna is coordinating an international research project, which investigates the effectiveness of tried and tested medicines for the treatment of some of the heaviest burdens of our modern society including diseases such as cancer, diabetes and cardiovascular diseases. One molecule that these disorders have in common is a receptor known as the calcium-sensing receptor (CaSR), which is the molecular starting point of this project.

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.

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.

APOE ε4 predicts risk of future depression

One of the most powerful predictors in neuropsychiatry is the epsilon 4 (ε4) allele of the apolipoprotein gene (APOE).

HIV, Ebola appear to be of animal origin

The hepatitis A virus can trigger acute liver inflammation which generally has a mild course in small children but which can become dangerous in adults.

Researchers develop biochemical trick that can extend lifespan of peptides

Researchers at University of the Pacific have developed a biochemical trick that can significantly extend the lifespan of peptides, smaller cousins of proteins. The finding opens up new possibilities for creating peptides to treat cancer, infertility and other conditions.

Preschoolers' working memory can predict later dropout risk

Preschoolers who score lower on a working memory task are likely to score higher on a dropout risk scale at the age of 13, researchers at Université Sainte-Anne and the University of Montreal revealed today.

Scientists identify protein that helps map brain tumours

Scientists have discovered a protein that helps map the edge of brain tumours more clearly so they show up on magnetic resonance imaging (MRI) scans, according to new research presented at the National Cancer Research Institute Cancer Conference in Liverpool today.
