New material advances tissue engineering, drug delivery

Researchers at the New York University Polytechnic School of Engineering have broken new ground in the development of proteins that form specialized fibers used in medicine and nanotechnology. For as long as scientists have been able to create new proteins that are capable of self-assembling into fibers, their work has taken place on the nanoscale. For the first time, this achievement has been realized on the microscale—a leap of magnitude in size that presents significant new opportunities for using engineered protein fibers.

Research could pave way for more effective drugs to treat inflammation

Six Case Western Reserve scientists are part of an international team that has discovered two compounds that show promise in decreasing inflammation associated with diseases such as ulcerative colitis, arthritis and multiple sclerosis.

Growth factor boosts natural defence against auto-immune diseases

Our immune system defends us from harmful bacteria and viruses, but, if left unchecked, the cells that destroy those invaders can turn on the body itself, causing auto-immune diseases like type-1 diabetes or multiple sclerosis. A molecule called insulin-like growth factor-1 (IGF-1) boosts the body's natural defence against this 'friendly fire', scientists at the European Molecular Biology Laboratory in Monterotondo, Italy, have found.

Researchers reveal how particular melanoma cells help tumors resist drugs

UNC School of Medicine researchers have pinpointed a set of intriguing characteristics in a previously unknown subpopulation of melanoma cancer cells in blood vessels of tumors. These cells, which mimic non-cancerous endothelial cells that normally populate blood vessels in tumors, could provide researchers with another target for cancer therapies.

Longer looks: Obamacare in the midterm campaign; watching Ebola mutate; lessons on dying

According to Kantar Media, a firm that tracks political advertising, health care is the main subject of campaign ads, especially Republican ones. Obamacare is unpopular - over half of Americans disapprove of it. Republicans talk about it constantly on the campaign trail, though not as intemperately as they did during their own party's primaries. Democrats scarcely mention it (10/18).

Novel 'designer' nanodevice could improve cancer diagnostics, treatment

Cancer diagnostics and treatment options could be drastically improved with the creation of a 'designer' nanodevice being developed by researchers from the UK, Italy, the US and Argentina.

YEDA and XL-protein sign deal to commercialize PASylated IFN superagonis

YEDA Research and Development Company Ltd., the technology transfer arm of the Weizmann Institute of Science, Israel, and XL-protein GmbH, Germany, a privately owned biopharmaceutical company, have signed a business collaboration agreement to commercialize a PASylated interferon superagonist -- PAS-YNSα8 -- which has been jointly developed by scientists at the Weizmann Institute and XL-protein.

New study reveals how cancer becomes drug resistant over time

Like a colony of bacteria or species of animals, cancer cells within a tumor must evolve to survive. A dose of chemotherapy may kill hundreds of thousands of cancer cells, for example, but a single cell with a unique mutation can survive and quickly generate a new batch of drug-resistant cells, making cancer hard to combat.

TSRI scientists identify long-sought activating molecules for subset of immune system cells

Scientists at The Scripps Research Institute (TSRI) have identified the long-sought activating molecules for a rare but crucial subset of immune system cells that help rally other white blood cells to fight infection.

Major scientific breakthrough in understanding retinal degenerative diseases that cause blindness

An important scientific breakthrough by a team of IRCM researchers led by Michel Cayouette, PhD, is being published today by The Journal of Neuroscience. The Montréal scientists discovered that a protein found in the retina plays an essential role in the function and survival of light-sensing cells that are required for vision.

New treatment strategy may improve repair process after heart attack

In a study that could point the way toward a new strategy for treating patients after a heart attack, UCLA stem cell researchers led by associate professor of medicine (cardiology) and Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research member Dr. Arjun Deb have discovered that some scar-forming cells in the heart, known as fibroblasts, have the ability to become endothelial cells (the cells that form blood vessels).

Four out of ten children in Burkina Faso genetically resistant to virus strains

Every year rotavirus causes half a million diarrhoea-related deaths amongst children in developing countries. Existing vaccines provide poor protection. The reason could be a widespread genetic resistance amongst children, according to virologists at Linköping University.

Research findings point toward new therapeutic target for aggressive breast cancer

One of the first-known oncogenes has a protein partner that helps breast cancer proliferate and when it's blocked, so is the cancer, scientists report.

Melanoma cells create own 'green light' signal to spread in the body

CANCER RESEARCH UK scientists have discovered that melanoma cells are drawn to follow the 'trail' of a naturally-occurring molecule in the body, which directs this serious type of skin cancer to spread, according to research published today (Tuesday) in PLOS Biology.
