New methods of gene delivery using lasers

...cope. The new technique involves the violet laser being focused onto cell membranes for a fraction of a second ?this causes the membrane to open up, allowing foreign genes to enter. The cell’s internal mechanism causes the membrane of the cell to heal itself thus appearing to suffer no long-lasting damage...

RNA project to create language for scientists worldwide

...re expressed to make proteins." They are unique in being able to store and transmit information as well as process that information. The continuous discovery of new RNA molecules with novel biological functions is beginning to show that RNA plays far more roles than originally believed. For instance, whil...

TEL2 gene cooperates with MYC gene to provoke B-cell lymphomas

...ptosis in the precancerous B lymphocytes that were being forced to multiply by MYC." But even the combined effect of MYC and TEL2 wasn't enough to turn these overactive lymphocytes into lymphoma cells. "The coup de grace consisted of a complete elimination of the apoptotic response through loss of p53 fu...

Falling ants glide back to trunk to avoid dangers of forest floor

Scientists discover that host cell lipids facilitate bacterial movement

...eria causes a variety of diseases, the most severe being meningoencephalitis, an inflammation of the brain and the membranes that envelop the brain and spinal cord. Infection begins when the bacterium binds to a receptor on the surface of a cell, causing the cell to ingest it. The bacterium multiplies insi...

Love at first smell

Even males previously rejected by females were rendered irresistible after the synthetic perfume had been applied. Smell is important when choosing a partner, not only for humans but also fish. To fight disease, the body'...

Affymetrix and the Karolinska Institutet Announce Translational Medicine Strategic Alliance

...from diagnosing and treating existing diseases, to being able to predicting disease susceptibility and an individual's response to drugs," said Patrick Kelly, European Site Manager and Vice President, Affymetrix. "This is what personalized medicine is all about -- enabling clinicians to detect diseases ear...

Carnegie Mellon scientists develop tool that uses MRI to visualize gene expression in living animals

...r and arthritis, to detect where and when they are being expressed," Ahrens said. Existing methods used to image gene expression have limitations, according to Ahrens. Some methods cannot be used in living subjects, fail to image cells deep inside the body or don't provide high-resolution images. Other ap...

Ideas for coordinated actions (CAs), specific targeted research projects (Streps), specific support actions (SSAs) are welcomed and, according ...

Gene therapy for Parkinson's disease moves forward in animals

Implanted Devices Detect High-Risk Heart Failure Patients

...ythmias that can lead to sudden death, with CRT-Ds being the latest technology. CRT-Ds perform two main functions. First, the devices electrically stimulate both sides of the heart in coordinated fashion, which optimizes the contractability of already weakened heart muscle. Second, the defibrillator "shoc...

VCU Researchers Identify Networks Of Genes Responding To Alcohol In The Brain

...ed on," eventually leading to more or less protein being produced by that particular gene. Changes in a gene's expression are thought to be an important mechanism underlying long-term memory and learning, including that which occurs with addiction to alcohol or other drugs, Miles said. In the study, appro...

Rush Physicians Using Gene Therapy For Heart Patients With Moderate To Severe Chest Pains Who Do Not Benefit From Other Treatments

...ation may benefit from a new gene therapy approach being used by cardiologists at Rush University Medical Center to grow new blood vessels in the heart. The phase II clinical research study uses vascular endothelial growth factor-2 (VEGF-2) in the form of a solution containing a DNA plasmid that is delive...

Ophthalmologists Use Artificial Silicon Retina Microchip To Treat Vision Loss
