Spherical nucleic acids could revolutionize biomedicine

Northwestern University's Chad A. Mirkin, a world-renowned leader in nanotechnology research and its application, has invented and developed a powerful material that could revolutionize biomedicine: spherical nucleic acids (SNAs).

TSG might be novel compound for treatment of Alzheimer's and dementia with Lewy body

Administration of the active compound tetrahydroxystilbene glucoside (TSG) derived from the Chinese herbal medicine Polygonum multiflorum Thunb, reversed both overexpression of α-synuclein, a small protein found in the brain, and its accumulation using a mouse model of Alzheimer's disease.

Study finds little long-term survival advantage for women with ovarian cancer and BRCA mutations

Researchers at Moffitt Cancer Center and colleagues in Toronto and at Yale University studied the long-term survival of women with a BRCA1 or BRCA2 gene mutation who were diagnosed with invasive ovarian cancer. They found that the short-term benefit to having either mutation does not lead to a long-term survival benefit.

Tau release from healthy neurons can be regulated by neuronal activity

Researchers from King's College London have discovered that neuronal activity can stimulate tau release from healthy neurons in the absence of cell death.

Emory receives NINDS grant for biomarker research on Parkinson's

The National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health (NIH), awarded a three-year, $900,000 grant to the Center for Biomedical Imaging Statistics at Emory's Rollins School of Public Health.

Prions may be crucial in brain development during childhood

A molecule that is not only dangerous, but can help the brain grow. A few years ago it was found that certain proteins, the prions, when defective are dangerous, as they are involved in neurodegenerative syndromes such as the Creutzfeldt-Jakob and the Alzheimer diseases.

Canine Pompe disease can now be diagnosed with genetic test

Pompe disease, a severe glycogen storage disease appearing in Lapphunds is caused by a genetic defect in acid α-glucosidase gene. The same genetic mutation also causes the equivalent disease in humans. Based on this finding, canine Pompe disease can now be diagnosed with a genetic test.

Cigarette smoke mediates epigenetic repression of miR-487b during pulmonary carcinogenesis

Recent studies have identified correlations between cigarette smoke-induced microRNA (miRNA) expression and different aspects of lung cancer; however, it is unclear how miRNA expression directly contributes to carcinogenesis.

Diabetes increases mortality after myocardial infarction by oxidizing CaMKII enzyme

Diabetic patients are more than twice as likely to die from a heart attack as non-diabetic patients, but the mechanisms that underlie increased heart attack-related mortality in diabetic patients are unknown. High levels of the oxidized form of the protein CamKII (ox-CaMKII) have been linked to increased risk of sudden death after heart attack.

'Primitive' reflexes may involve more sophisticated brain function than previously thought

Supposedly 'primitive' reflexes may involve more sophisticated brain function than previously thought, according to researchers at Imperial College London.

IKBKE gene plays a key role in tobacco-induced lung cancer

Researchers at Moffitt Cancer Center have found a potential targeted therapy for patients with tobacco-associated non-small cell lung cancer. It is based on the newly identified oncogene IKBKE, which helps regulate immune response.

Central College to study effects of triclosan on heart rate

How often does a heart beat? For a zebrafish, it depends on the water it's swimming in. Ellen Du Pre, professor of biology at Central College, is working with four students, as well as biology colleague Nicole Palenske, to study the effects of triclosan on heart rate. The tiny fish, which can be as small as an eyelash when newly hatched, is transparent, and the students can easily count the heart beats under a microscope.

Study identifies regions of genes linked to Beh-et's disease

Researchers don't know the exact cause of Beh-et's disease, a chronic condition that leads to oral and genital sores and serious complications such as blindness, but new research brings better understanding to what makes some people more susceptible to being affected.

Gedunin could help kill cancer cells

Scientists at the Georgia Regents University Cancer Center have identified an Indian plant, used for centuries to treat inflammation, fever and malaria, that could help kill cancer cells.

VNI cures both acute and chronic forms of Chagas disease

Chagas disease, a deadly tropical infection caused by the protozoan parasite Trypanosoma cruzi and transmitted by biting insects called "kissing bugs," has begun to spread around the world, including the U.S. Yet current treatment is toxic and limited to the acute stage.

New insights into how cells stick to each other and to other bodily structures

Research carried out by scientists at the Georgia Institute of Technology and The University of Manchester has revealed new insights into how cells stick to each other and to other bodily structures, an essential function in the formation of tissue structures and organs. It's thought that abnormalities in their ability to do so play an important role in a broad range of disorders, including cardiovascular disease and cancer.

Protein-restricted diet supplemented with IGF-I may protect from Alzheimer's

Mice with many of the pathologies of Alzheimer's Disease showed fewer signs of the disease when given a protein-restricted diet supplemented with specific amino acids every other week for four months.

Selumetinib shrinks tumors in women with low-grade ovarian cancer

Researchers at The University of Arizona Cancer Center at St. Joseph's Hospital and Medical Center in Phoenix have discovered that many women with low-grade serous carcinoma of the ovary or peritoneum have seen their tumors stabilize or shrink after taking a regular dose of the compound selumetinib.
