Obesity and oxidative stress: an interview with Dr Elizabeth New

Even though oxygen is essential for us to live, it can react with other compounds in the body to produce molecules called free radicals, which are highly reactive and damaging.

Scientists discover telomerase as cause of chronic inflammation in human cancers

A*STAR scientists have identified the enzyme, telomerase, as a cause of chronic inflammation in human cancers. Chronic inflammation is now recognized as a key underlying cause for the development of many human cancers, autoimmune disorders, neurodegenerative diseases, and metabolic diseases such as diabetes.

Somnogen induces sleep in patients with primary hypersomnia

Researchers at Emory University School of Medicine have discovered that dozens of adults with an elevated need for sleep have a substance in their cerebrospinal fluid that acts like a sleeping pill.

UPR pathway helps tumor cells escape apoptosis during development of lymphoma

A pathway called the "Unfolded Protein Response," or UPR, a cell's way of responding to unfolded and misfolded proteins, helps tumor cells escape programmed cell death during the development of lymphoma.

Regorafenib able to control resistant gastrointestinal stromal tumor

A new targeted drug demonstrated its ability to control metastatic gastrointestinal stromal tumor, an uncommon and life-threatening form of sarcoma, after the disease had become resistant to all existing therapies, report investigators at Dana-Farber Cancer Institute who led the worldwide clinical trial.

Study: 2-PMPA improves cognition in mice with MS

Johns Hopkins researchers report the successful use of a form of MRI to identify what appears to be a key biochemical marker for cognitive impairment in the brains of people with multiple sclerosis (MS). In follow-up experiments on mice with a rodent form of MS, researchers were able to use an experimental compound to manipulate that same marker and dramatically improve learning and memory.

Novel technology can lead to more efficient and cheaper therapy for Pompe disease

VIB researchers from UGent and Vrije Universiteit Brussel , together with a team of the firm Oxyrane have developed a new technology that can lead to a more efficient and possibly also cheaper therapy for diseases such as Pompe disease. Oxyrane will now start developing a clinical program for this therapy in Pompe disease.

Synthetic membrane channels can be constructed through DNA nanotechnology

As reported in the journal Science, physicists at the Technische Universitaet Muenchen (TUM) and the University of Michigan have shown that synthetic membrane channels can be constructed through "DNA nanotechnology."

Glycoprotein gene flags up heart disease

The glycosylphosphotidylinositol-anchored membrane glycoprotein CD14 gene significantly predicts cardiovascular mortality in adults aged 65 years or over, research shows.

Hsp104 protein switches mechanism to break up amyloid versus disordered clumps

Several fatal brain disorders, including Parkinson's disease, are connected by the misfolding of specific proteins into disordered clumps and stable, insoluble fibrils called amyloid. Amyloid fibrils are hard to break up due to their stable, ordered structure. For example, α-synuclein forms amyloid fibrils that accumulate in Lewy Bodies in Parkinson's disease. By contrast, protein clumps that accumulate in response to environmental stress, such as heat shock, possess a less stable, disordered architecture.

Biomolecular imaging: an interview with Professor Roger Reddel

The reason Children’s Medical Research Institute (CMRI) exists is to find ways to treat or prevent childhood disease. Our research programs are focussed on the areas of cancer cell growth, nerve cell signalling, embryology and gene therapy. These four programs have a shared aim of translating novel findings into new treatments for the benefit of families everywhere.

Scientists discover new mode of action for enzymes immersed in cellular membranes

Johns Hopkins scientists have discovered a new mode of action for enzymes immersed in cellular membranes. Their experiments suggest that instead of recognizing and clipping proteins based on sequences of amino acids, these proteases' location within membranes gives them the unique ability to recognize and cut proteins with unstable structures.

Two studies investigate role of oxygen in cell transplantation

Two studies published in the current issue of Cell Transplantation, now freely available on-line, investigate the role of oxygen in cell transplantation.

Possible link between mind wandering and aging

Scientific studies have suggested that a wandering mind indicates unhappiness, whereas a mind that is present in the moment indicates well-being. Now, a preliminary UCSF study suggests a possible link between mind wandering and aging, by looking at a biological measure of longevity.

Combination of Abraxane and gemcitabine improves survival of patients with pancreatic cancer

A new cancer drug combination demonstrated significant improvement in overall survival of late-stage pancreatic cancer patients compared to those receiving standard treatment, according to results of a Phase III clinical trial led by physicians from Scottsdale Healthcare's Virginia G. Cancer Center Clinical Trials, a partnership with the Translational Genomics Research Institute (TGen).
