Researchers observe membrane repair in real-time in a living organism

Every cell is enclosed by a thin double layer of lipids that separates the distinct internal environment of the cell from the extracellular space. Damage to this lipid bilayer, also referred to as plasma membrane, disturbs the cellular functions and may lead to the death of the cell. For example, downhill walking tears many little holes into the plasma membranes of the muscle cells in our legs.

Researchers discover molecular mechanism responsible for low back pain

Italian researchers at the Catholic University of Sacred Heart in Rome found an important molecular mechanism responsible for low back pain and other acute vertebral problems like cervical axial pain, all due to aging and degeneration of the vertebral column.

Rats’ decision making as good as humans: Study

It is a known fact that rats are smart. But now US researchers have shown that they may be just as good as humans at juggling information in order to make the best decision. The discovery could help scientists better understand how the brain works in order to help people with autism who have difficulty processing various stimuli the way that others can, said the study authors.

Researchers identify molecule that helps decrease acute GVHD severity

Researchers have identified a molecule that helps control the severity of graft-versus-host disease, a life-threatening complication for many leukemia patients who receive a bone-marrow transplant.

Two scientists receive The Brain Prize 2012 for pioneering work on hearing and deafness

The Grete Lundbeck European Brain Research Foundation announced today that The Brain Prize 2012 is jointly awarded to Christine Petit and Karen Steel.

Genetically modified pig may hold keys to develop treatments for RP

A newly developed, genetically modified pig may hold the keys to the development of improved treatments and possibly even a cure for retinitis pigmentosa (RP), the most common inherited retinal disease in the United States.

Researchers validate CatB protease as target for Alzheimer's

Researchers at the University of California, San Diego, the Medical University of South Carolina, the University of Cincinnati, and American Life Science Pharmaceuticals of San Diego have validated the protease cathepsin B (CatB) as a target for improving memory deficits and reducing the pathology of Alzheimer's disease (AD) in an animal model representative of most AD patients.

Blocking Plexin B1 protein can prevent formation of breast cancer metastases

In particularly aggressive forms of breast cancer, cancer cells can settle in other organs and form metastases there. Once such metastases form, complete recovery is rare. Consequently, it is enormously important to prevent the metastasisation of the breast cancer cells. The success, however, achieved by using existing forms of therapy is limited.

Inhalation of nitric oxide could help improve blood flow to ischemic brain

LMU researchers developed a new strategy for the treatment of stroke, which could help to improve blood flow to ischemic brain. Strokes are due to a localized reduction in the blood supply to the brain, mainly due to the blockage of a vessel by a blood clot.

CLR01 blocks toxic aggregations of proteins in mouse model of Parkinson's

Millions of people suffer from Parkinson's disease, a disorder of the nervous system that affects movement and worsens over time. As the world's population ages, it's estimated that the number of people with the disease will rise sharply. Yet despite several effective therapies that treat Parkinson's symptoms, nothing slows its progression.

Study offers hope for novel approach to prevent AD

As scientists struggle to find an effective way to prevent Alzheimer's disease, researchers at the University of Wisconsin-Madison may have found a new approach to interrupting the process that leads to the devastating disease.

Report highlights benefits of Nuvilex's cell encapsulation technology for diabetes

Nuvilex, Inc., an emerging biotechnology provider of cell and gene therapy solutions, today provided additional details based on the Goldman Small Cap Research report issued February 29, 2012, that highlighted the company's cell encapsulation technology and its benefits for treating chronic diseases such as diabetes.

U-M summit to focus on shortage of medical technologies for children

The University of Michigan is hosting the three-day summit that will focus attention on the widespread shortage of medical technologies to help sick children.

Varenicline improves walking ability in patients with SCA3

A nicotinic drug approved for smoking cessation significantly improved the walking ability of patients suffering from an inherited form of ataxia, reports a new clinical study led by University of South Florida researchers.

Chemists build light-controlled neural inhibitor

The notion of a pain switch is an alluring idea, but is it realistic? Well, chemists at LMU Munich, in collaboration with colleagues in Berkeley and Bordeaux, have now shown in laboratory experiments that it is possible to inhibit the activity of pain-sensitive neurons using an agent that acts as a photosensitive switch. For the LMU researchers, the method primarily represents a valuable tool for probing the neurobiology of pain.

Causal link between TBI and increased susceptibility to PTSD

Mild traumatic brain injury (TBI) and posttraumatic stress disorder (PTSD) are cardinal injuries associated with combat stress, and TBI increases the risk of PTSD development. The reasons for this correlation have been unknown, in part because physical traumas often occur in highly emotional situations.

DNA ‘nanorobot’ effectively targets cancer leaving healthy cells untouched: Study

Researchers have developed ‘nano-sized’ probes built from DNA that can seek and destroy cancer cells, leaving healthy cells untouched. These ‘nanorobots’ release their drug payload only when they reach and identify their target and are believed to improve many treatments for disease.

Study reveals immune mechanism for surveillance over EBV infection

Some 90 percent of people are exposed to the Epstein Barr virus (EBV) at some point in their life. Even though it is quickly cleared from the body, the virus can linger silently for years in small numbers of infected B cells.

Scientists observe maturation of immune cells in live zebrafish embryos

T-cells are the immune system's security force. They seek out pathogens and rogue cells in the body and put them out of action. Their precursors are formed in the bone marrow and migrate from there into the thymus. Here, they mature and differentiate to perform a variety of tasks. Scientists at the Max Planck Institute of Immunobiology and Epigenetics in Freiburg have now succeeded for the first time in observing the maturation of immune cells in live zebrafish embryos.
