New method allows controlled release of drugs; could help develop targeted treatments

Researchers have discovered a method that allows for the controlled release of an active agent on the basis of a magnetic nanovehicle.

Study shows promising results for cancer treatment

The plasma membrane transporter SLC5A8 can inhibit the spread of tumours by decreasing the amount of the anti-apoptotic protein surviving in tumour cells.

Researchers discover safe and efficient way to get large molecules through the cell membrane

Living cells are surrounded by a membrane that tightly regulates what gets in and out of the cell. This barrier is necessary for cells to control their internal environment, but it makes it more difficult for scientists to deliver large molecules such as nanoparticles for imaging, or proteins that can reprogram them into pluripotent stem cells.

Institute of Bioengineering and Nanotechnology, IBM reveal new antimicrobial hydrogel

Researchers from IBM and the Institute of Bioengineering and Nanotechnology revealed today an antimicrobial hydrogel that can break through diseased biofilms and completely eradicate drug-resistant bacteria upon contact.

CD98hc molecule appears to be necessary for rapid and effective skin renewal

These mechanisms, described in vivo in mice, engage molecule CD98hc, which is involved in epidermis renewal and could be an indicator of the skin's capacity for regeneration.

Research on dystrophin gene sequence could lead to treatments for Duchenne muscular dystrophy

Muscular dystrophy is caused by the largest human gene, a complex chemical leviathan that has confounded scientists for decades. Research conducted at the University of Missouri and described this month in the Proceedings of the National Academy of Sciences has identified significant sections of the gene that could provide hope to young patients and families.

Very low levels of BPS can disrupt natural estrogen hormone actions

A few years ago, manufacturers of water bottles, food containers, and baby products had a big problem. A key ingredient of the plastics they used to make their merchandise, an organic compound called bisphenol A, had been linked by scientists to diabetes, asthma and cancer and altered prostate and neurological development.

Eardrum crust aids perforation healing if timing is right

How and when “crust” forms at the margin of a tympanic membrane perforation may serve as a predictor for healing outcome, research suggests.

Novel infertility mechanism suggested in men with metabolic syndrome

Men diagnosed with the metabolic syndrome appear to have reduced fertility potential despite the absence of leucocytospermia, report researchers.

Researchers report novel charge zipper principle used by proteins to form functional units

Membrane proteins are the "molecular machines" in biological cell envelopes. They control diverse processes, such as the transport of molecules across the lipid membrane, signal transduction, and photosynthesis. Their shape, i.e. folding of the molecules, plays a decisive role in the formation of, e.g., pores in the cell membrane.

New math model may help predict colon cancer resistance to chemotherapy

Scientists may be able to better predict which patients with colorectal cancer will respond to chemotherapy using a new mathematical model that measures the amount of stress required for a cancer cell to die without harming healthy tissue. The results of this study are published in Cancer Research, a journal of the American Association for Cancer Research.

Study examines consequences of muscle activity with surprising results

A study in The Journal of General Physiology examines the consequences of muscle activity with surprising results, indicating that the extracellular accumulation of potassium that occurs in working muscles is considerably higher than previously thought.

New system based on photonic biosensors can rapidly diagnose food allergies

Researchers at the Institute of Materials Science of the Universitat de València, in consortium with various European companies and institutions, are developing a system based on photonic biosensors for rapid diagnosis of food allergies.

Clathrin protein may have a role in suppressing tumors

Newly published research by Indiana University structural biologist Joel Ybe and colleagues identifies a "topology switch" in the protein clathrin, the function of which may shed light on molecular processes involved in tumor suppression.

Aggressive breast cancer’s metastasis molecular switch identified

Scientists at Weill Cornell Medical College have discovered the molecular switch that allows aggressive triple negative breast cancer cells to grow the amoeba-like protrusions they need to crawl away from a primary tumor and metastasize throughout the body. Their findings, published in Cancer Cell, suggest a novel approach for developing agents to treat cancer once it has spread.

New hope for people with sound-induced deafness

Preliminary results from a study in mice suggest it may be possible to regenerate cochlear hair cells that have been damaged due to excessive noise exposure.

Graft recommendation bursts onto eardrum repair scene

Researchers say that a 0.2-mm partial thickness graft is optimal for reconstruction of subtotal tympanic membrane perforation.

Blocking interaction of JNK enzyme may counteract neuron destruction

Oxidative stress is a primary villain in a host of diseases that range from cancer and heart failure to Alzheimer's disease, Amyotrophic Lateral Sclerosis and Parkinson's disease.

New information on insulin and cell bonding mechanics

The discovery of insulin nearly a century ago changed diabetes from a death sentence to a chronic disease. Today a team that includes researchers from Case Western Reserve University School of Medicine announced a discovery that could lead to dramatic improvements in the lives of people managing diabetes.

TSRI chemists develop new cell-marking method

Chemists at The Scripps Research Institute (TSRI) have found an easier way to perform one of the most fundamental tasks in molecular biology. Their new method allows scientists to add a marker to certain cells, so that these cells may be easily located and/or selected out from a larger cell population.
