MicroRNAs key to memory and learning process

Studying tiny bits of genetic material that control protein formation in the brain, Johns Hopkins scientists say they have new clues to how memories are made and how drugs might someday be used to stop disruptions in the process that lead to mental illness and brain wasting diseases.

High blood pressure due to stress maybe due to the immune system

If stress is giving you high blood pressure, blame the immune system. T cells, helpful for fighting infections, are also necessary for mice to show an increase in blood pressure after a period of psychological stress, scientists have found.

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.

Nuvilex overcomes fundamental challenges faced in stem cell therapy

Nuvilex, Inc., an emerging biotechnology provider of cell and gene therapy solutions, released information today about the company's cell encapsulation technology and the breakthrough in stem cell research which overcomes specific fundamental challenges faced in stem cell therapy—host rejection and migration of implanted cells away from the target site.

Researchers identify mechanism with which cancer cells protect themselves against damage

Although many cancer drugs have already been in use for decades, their mode of action is still unknown. The new research results now challenge a mechanism of action that was previously proposed for a group of drugs and supported with experiments: the Topoisomerase I-inhibitor Camptothecin (Top1 inhibitor for short) and its derivatives used in chemotherapy, Topotecan and Irinotecan.

Inovio's SynCon vaccine for HPV types 6 and 11 induces CD8+ T cells in mice

Inovio Pharmaceuticals, Inc. announced today that its SynCon therapeutic vaccine for human papillomavirus (HPV) types 6 and 11, which are associated with head & neck cancers and genital warts, among other conditions, induced strong antigen-specific CD8+ T cells in mice.

Study: Bioavailability similar among four subcutaneous IgG preparations

Data presented by CSL Behring today suggest that the bioavailability of immunoglobulin G (IgG) therapies is consistent when patients with primary immunodeficiencies switch from one IgG product to another by the subcutaneous route.

Bovine collagen can enhance gum healing

Receding gums often result in tooth sensitivity and can lead to decay of the root and persistent inflammation of the gum. New research published in BioMed Central's open access journal Head & Face Medicine demonstrates that a novel method using bovine collagen is able to enhance gum healing. This resulted in thicker margins around the tooth and, in over half the cases, complete coverage of exposed roots.

X-rays help decipher how natural antibiotics defy a longstanding set of chemical rules

Researchers working at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have used powerful X-rays to help decipher how certain natural antibiotics defy a longstanding set of chemical rules - a mechanism that has baffled organic chemists for decades.

Study shows how hydra respond to light in the absence of eyes

In the absence of eyes, the fresh water polyp, Hydra magnipapillata, nevertheless reacts to light. They are diurnal, hunting during the day, and are known to move, looping end over end, or contract, in response to light.

Brain more flexible and trainable than previously thought

Opening the door to the development of thought-controlled prosthetic devices to help people with spinal cord injuries, amputations and other impairments, neuroscientists at the University of California, Berkeley, and the Champalimaud Center for the Unknown in Portugal have demonstrated that the brain is more flexible and trainable than previously thought.

Scientists discover how to enhance production of hepatocytes to repair damaged liver tissue

Scientists have shed light on how the liver repairs itself with research that could help develop drugs to treat liver disease.

Deficits in mirror neuron system contribute to social impairments in ASD

Impaired social function is a cardinal symptom of autism spectrum disorders (ASDs). One of the brain circuits that enable us to relate to other people is the "mirror neuron" system. This brain circuit is activated when we watch other people, and allows our brains to represent the actions of others, influencing our ability to learn new tasks and to understand the intentions and experiences of other people.

New APS policy requires reporting of sex and gender in experimental studies

The American Physiology Society (APS) has announced a new policy requiring the reporting of the sex of experimental animals and the sex or gender of humans used in studies submitted for publication in any of the organization's 13 peer-reviewed journals.

Water treated with ozone eradicates prions

A University of Alberta research team has discovered that technology commonly used to decontaminate food industry equipment can also rid meat processing plants of lethal microbial material responsible for the human version of the ailment Mad Cow disease.

Rigosertib drug shows promise against advanced pancreatic cancer

The American Cancer Society estimates that 44,000 new cases of pancreatic cancer will be diagnosed this year and that 37,000 people will die from the disease. These are not strong odds. A new drug, rigosertib, allows pancreatic cancer cells to rush through replication - and then stops them cold, killing them in in the middle of a step called M phase. Healthy cells that don't rush are unharmed.

R-loop formation may drive under-methylation and autoimmunity

Researchers at the University of California, Davis, have figured out how the human body keeps essential genes switched "on" and silences the vast stretches of genetic repeats and "junk" DNA.

Ion channels assembled in different combinations distinguish temperatures

The winter sun feels welcome, but not so a summer sunburn. Research over the past 20 years has shown that proteins on the surface of nerve cells enable the body to sense several different temperatures. Now scientists have discovered how just a few of these proteins, called ion channels, distinguish perhaps dozens of discrete temperatures, from mildly warm to very hot.
