RNA switches can better equip and regulate viruses for many therapeutic applications

Numerous viruses are used in the service of science today. They serve as gene taxis to transfer therapeutic genes into body cells or as therapeutic viruses targeted to infect and destroy cancer cells. For such applications, the viruses are often equipped with additional genes, such as for immune mediators or for proteins inducing programmed cell death. However, these gene products can harm the body if they are released at the wrong moment or at excessive levels.

Researchers report how Alzheimer's protein deposits disrupt signalling between nerve cells

How abnormal protein deposits in the brains of Alzheimer's patients disrupt the signalling between nerve cells has now been reported by researchers in Bochum and Munich, led by Dr. Thorsten M-ller from the Medizinisches Proteom-Center of the Ruhr-Universit-t, in the journal Molecular and Cellular Proteomics. They varied the amount of APP protein and related proteins associated with Alzheimer's disease in cell cultures, and then analysed how this manipulation affected other proteins in the cell.

IntelliCell seeks patent for new mechanical method to separate SVF from blood vessels in fat

IntelliCell BioSciences, Inc. announced today that it has filed a patent application for a new mechanical method to separate stromal vascular fraction (SVF) from the blood vessels in adipose tissue (fat) to be used clinically in regenerative medicine.

Musical memory organized at least partially independent of the hippocampus

Together with his team, Prof. Christoph Ploner, director of the Department of Neurology at the Virchow campus, examined a professional cellist who suffered from encephalitis caused by a herpes virus. As a result of the inflammation, the patient developed serious disturbances in memory. Both his memory for the past (retrograde amnesia), as well as the acquisition of new information (anterograde amnesia) were affected.

SSEA4+ marker helps identify and isolate precursors of insulin-producing pancreatic cells

For the millions of people worldwide with type 1 diabetes who cannot produce sufficient insulin, the potential to transplant insulin-producing cells could offer hope for a long-term cure. The discovery of a marker to help identify and isolate stem cells that can develop into insulin-producing cells in the pancreas would be a critical step forward and is described in an article in BioResearch Open Access, a new bimonthly peer-reviewed open access journal from Mary Ann Liebert, Inc.

Study on sea lamprey may indicate how potentially deleterious genes can be controlled

Research on a unique vertebrate called the sea lamprey shows that more than a thousand genes are shed during its early development.

Chimpanzees from African sanctuaries carry drug-resistant strains of Staph

Chimpanzees from African sanctuaries carry drug-resistant, human-associated strains of the bacteria Staphlyococcus aureus, a pathogen that the infected chimpanzees could spread to endangered wild ape populations if they were reintroduced to their natural habitat, a new study shows.

Mof protein plays a key role in epigenetics of stem cells

How do stem cells preserve their ability to become any type of cell in the body? And how do they "decide" to give up that magical state and start specializing? If researchers could answer these questions, our ability to harness stem cells to treat disease could explode. Now, a University of Michigan Medical School team has published a key discovery that could help that goal become reality.

Reasoning and behavioral control dependent on different regions of frontal lobes

The frontal lobes are the largest part of the human brain, and thought to be the part that expanded most during human evolution. Damage to the frontal lobes-which are located just behind and above the eyes-can result in profound impairments in higher-level reasoning and decision making. To find out more about what different parts of the frontal lobes do, neuroscientists at the California Institute of Technology (Caltech) recently teamed up with researchers at the world's largest registry of brain-lesion patients.

Study identifies how genetic mutations in the nervous system cause Duane Syndrome

A research team from King's College London and the University of Exeter Medical School has identified how a genetic mutation acts during the development of nerves responsible for controlling eye muscles, resulting in movement disorders such as Duane Syndrome, a form of squint.

Chemists develop new lab test to examine how DNA damage disrupts protein synthesis

Transcription is a cellular process by which genetic information from DNA is copied to messenger RNA for protein production. But anticancer drugs and environmental chemicals can sometimes interrupt this flow of genetic information by causing modifications in DNA.

Scientists unravel how brain cells encode pronunciation of individual vowels in speech

Diagnosed with Lou Gehrig's disease at 21, British physicist Stephen Hawking, now 70, relies on a computerized device to speak. Engineers are investigating the use of brainwaves to create a new form of communication for Hawking and other people suffering from paralysis. -Daily Mail

GM-CSF depletion suppresses pain in people with arthritis-related conditions

The research relates to a family of molecules firstly discovered in Melbourne that applied to blood cell development. One of these, granulocyte macrophage colony-stimulating factor or GM-CSF, acts as a messenger between cells acting at a site of inflammation.

Investigators discover biological explanation for why low levels of oxygen advance SMA symptoms

Investigators at Nationwide Children's Hospital may have discovered a biological explanation for why low levels of oxygen advance spinal muscular atrophy (SMA) symptoms and why breathing treatments help SMA patients live longer. The findings appear in Human Molecular Genetics.

Study highlights Nek9 protein as decisive factor in cell division

A study by the Institute for Research in Biomedicine (IRB Barcelona) and the Center for Genomic Regulation (acronym in Catalan CRG) highlights the protein Nek9 as a decisive factor in cell division, a fundamental process for both the development of an organism and tissue maintenance.

New silicon chips help identify patients with lupus

Researchers at the Stanford University School of Medicine and Intel Corp. have collaborated to synthesize and study a grid-like array of short pieces of a disease-associated protein on silicon chips normally used in computer microprocessors.

Neurally-interfaced hand prosthesis re-establishes communication between nervous systems

Amputation disrupts not only the peripheral nervous system but also central structures of the brain. While the brain is able to adapt and compensate for injury in certain conditions, in amputees the traumatic event prevents adaptive cortical changes. A group of scientists reports adaptive plastic changes in an amputee's brain following implantation of multielectrode arrays inside peripheral nerves.
