New vaccine candidate against leading cause of hospital-acquired infections

Researchers at Brigham and Women's Hospital (BWH) have discovered a new vaccine candidate for the bacterium Pseudomonas aeruginosa taking advantage of a new mechanism of immunity.

FDA approves KRAS gene mutation test for colorectal cancer

The U.S. Food and Drug Administration today approved the first genetic test that can help some colorectal cancer (CRC) patients and their doctors determine if the drug Erbitux (cetuximab) would be an effective treatment based on the absence of a gene mutation. The therascreen KRAS RGQ PCR Kit can provide information about the KRAS gene mutation in patients whose CRC has spread to other parts of their body (metastasized).

New optical microscope identifies rare breast cancer cells

The ability to distinguish and isolate rare cells from among a large population of assorted cells has become increasingly important for the early detection of disease and for monitoring disease treatments.

New insights into role and importance of exosomes and their targeted gene transcripts

In the July 6 issue of Cell Stem Cell, researchers at the University of California, San Diego School of Medicine describe how human epidermal progenitor cells and stem cells control transcription factors to avoid premature differentiation, preserving their ability to produce new skin cells throughout life.

Bioengineers develop microfluidic platform to mechanically confine cancer cells

It's well known in conventional biology that during the process of mammalian cell division, or mitosis, a mother cell divides equally into two daughter cells. But when it comes to cancer, say UCLA researchers, mother cells may be far more prolific.

Researchers to use nanoscopic clay for controlled release of drugs in patients

University of Granada and the Spanish Consejo Superior de Investigaciones Cient-ficas (CSIC) researchers will use nanoscopic clay for the controlled release of drugs in patients, with the aim of designing more efficient and less toxic drugs. This is a pilot research study that includes CSIC and University of Granada researchers and researchers from other institutions.

New class of injectable materials can stimulate tissue regeneration

The University of Nottingham has begun the search for a new class of injectable materials that will stimulate stem cells to regenerate damaged tissue in degenerative and age related disorders of the bone, muscle and heart.

Toxins and cell death: Interview with Professor Denise Montell

There are multiple kinds of cell death. Cells can undergo programmed cell death, which is a series of events that undergoes a predictable order at certain times during development.

Study represents starting point for future clinical applications using propolis

A team of researchers from the University of Valencia, the Universitat Politècnica de València, the University Hospital La Fe and the Universitat Autònoma de Barcelona conducted in vitro studies of cytotoxicity (cellular affection) to assess the optimal concentration level of propolis in which this natural substance extracted from bee resin would offer the maximum protection against ionised radiation and not be toxic for blood cells.

Study sheds light on the assembly of ribosome

Scientists from the Florida campus of The Scripps Research Institute have identified a series of intricate biochemical steps that lead to the successful production of proteins, the basic working units of any cell.

FDC precursor cells exist in the wall of blood vessels

Chronic inflammatory conditions are extremely common diseases in humans and in the entire animal kingdom. Both in autoimmune diseases and pathogen-caused diseases, the inflamed areas are rapidly colonized by antibody producing B lymphocytes - which organize themselves in highly structured areas called "lymphoid follicles".

PHF21A gene plays a big role in Potocki-Shaffer syndrome

A gene whose mutation results in malformed faces and skulls as well as mental retardation has been found by scientists.

MiR-125b downregulated in both aggressive and indolent forms of CLL

Loss of a particular microRNA in chronic lymphocytic leukemia shuts down normal cell metabolism and turns up alternative mechanisms that enable cancer cells to produce the energy and build the molecules they need to proliferate and invade neighboring tissue.

Peptides block MORs and curb appetite

Feeling full involves more than just the uncomfortable sensation that your waistband is getting tight. Investigators reporting online on July 5th in the Cell Press journal Cell have now mapped out the signals that travel between your gut and your brain to generate the feeling of satiety after eating a protein-rich meal. Understanding this back and forth loop between the brain and gut may pave the way for future approaches in the treatment and/or prevention of obesity.

Insight into understanding IDH mediated disease

Agios Pharmaceuticals, the leading biopharmaceutical company focused on discovering and developing novel drugs in cancer metabolism, announced today the publication of a new study that provides further evidence of the link between a mutated metabolic enzyme and acute myeloid leukemia (AML), one of the most common types of leukemia in adults.

Metformin can activate neural stem cells to encourage brain repair

The discovery is an important step toward therapies that aim to repair the brain not by introducing new stem cells but rather by spurring those that are already present into action, says the study's lead author Freda Miller of the University of Toronto-affiliated Hospital for Sick Children. The fact that it's a drug that is so widely used and so safe makes the news all that much better.

TPJ in brain carries information for decisions during social interactions

Although many areas of the human brain are devoted to social tasks like detecting another person nearby, a new study has found that one small region carries information only for decisions during social interactions. Specifically, the area is active when we encounter a worthy opponent and decide whether to deceive them.

Scientists discover new signalling pathway that controls both obesity and atherosclerosis

A*STAR scientists from the Institute of Molecular and Cell Biology (IMCB) and the Singapore Bioimaging Consortium (SBIC) have discovered a new signalling pathway that controls both obesity and atherosclerosis.

Scientists use antibody injections to rapidly reverse onset of Type I diabetes in mice

Scientists at the University of North Carolina School of Medicine have used injections of antibodies to rapidly reverse the onset of Type I diabetes in mice genetically bred to develop the disease. Moreover, just two injections maintained disease remission indefinitely without harming the immune system.

Reprogramming asthma-promoting immune cells diminishes airway damage and inflammation

Reprogramming asthma-promoting immune cells in mice diminishes airway damage and inflammation, and could potentially lead to new treatments for people with asthma, researchers have found.
