Experimental gene therapy 'abolishes' arthritis pain and lessens joint damage

...the just published study involved a technique that delivers gene therapy by injection at the joint, other promising approaches may involve interrupting crosstalk in the brain instead. Based on that promise, the Medical Center is in the process of founding a private biotech company to develop the technology. I...

First clinical trial of gene therapy for childhood blindness

...n these cells should restore vision. The operation delivers the normal genes to the retina, using a harmless virus or "vector" to carry the gene into the cells. The vector has been manufactured for this trial by Targeted Genetics, Seattle, USA. Previous work using animal models has demonstrated that this ...

Bones in motion: Brown scientists to create new 3-D X-ray system

...ld back by technology. Computed tomography, or CT, delivers detailed 3-D images, but CT scanners are too slow to capture rapid motion. Cinefluoroscopy, a technique that uses X-rays to view objects, can produce moving images in two dimensions, but not 3-D. An orthopedic surgeon trying to figure out the best...

Researchers design pulsed mircrojet system to deliver protein drugs without pain or bruising

...ns without using needles. "The microjet system delivers precise doses into superficial skin layers, thereby mitigating pain," says Samir Mitragotri, a professor of chemical engineering at UCSB and a lead author of the paper. The system was designed as an alternative to the macro-scale systems that had bee...

Cancer-killing invention also harvests stem cells

...e implanted surface, King's device captures it and delivers an apoptosis signal, a biochemical way of telling the cancer cell to kill itself. Within two days, that cancer cell is dead. Normal cells are left totally unharmed because the device selectively targets cancer cells. The apoptosis signal is del...

Organic is healthier: Kiwis prove that green is good

As well as covering industry and science, it focuses on developments that will be of significant commercial interest in five- to ten-years time. Published twice-monthly and free to SC...

Transplanted photoreceptor precursor cells restore visual function in mice with retinal degeneration

...." They are part of a complex sensory system that delivers visual signals to the brain. Photoreceptors consist of rods and cones, highly specialized cells that capture light and convert it into chemical signals that travel through the inner retina and optic nerve and on to the brain where signals are convert...

New biochip helps study living cells, may speed drug development

...microchip. With four electrodes per cell, the chip delivers 64 simultaneous, continuous sources of data. This additional data allows for a deeper understanding of cellular activity compared to current technology, which measures only one point outside one cell and cannot record simultaneously, Porterfield ...

Researchers use multiphoton microscopy to watch chromosomes in action

...penetrating power and can damage the specimen, MPM delivers crisp, clear images, even in thicker tissue samples like Drosophila salivary glands. The research was ultimately possible thanks to the unique composition of the fruit flies' so-called polytene cells, giant, multistranded chromosomes with hundreds...

Harmful Algal Blooms monitored from space in Chile

...ervice based on Earth Observation (EO) data, which delivers forecasts of potential HABs to aquaculture companies via a customised Internet portal. HABs are a natural phenomenon that have increased in frequency over the last 30 years, causing millions of Euros worth of annual losses to the 360 fish farms fou...

Natural vitamin E tocotrienol reaches blood at protective levels

... known as tocopherol transfer protein (TTP), which delivers TCP throughout the body, doesn't transport TCT very well. "Our results demonstrate that TCT is efficiently delivered to the bloodstream despite the fact that the transfer protein has a lower affinity for TCT than it has for TCP," Sen said. Absorpt...

BGSU biologist trying to crack microscopic code

... the defensive barrier, although which proteins it delivers energy to as part of that process isn't known. Finding that answer is a long-term objective, he adds, saying it could help lead to the development of a drug that could break the barrier. Some drugs already target the outer defenses of bacteria. P...

Study finds how organs monitor themselves during early development

...ealing commonalities across species; the fruit fly delivers cues. It is an animal in which processes are first discovered and which are later confirmed in humans. "Evolution works--what works for the fruit fly is the same principle that nature has put in place for us," says Dr. Gilboa. The implications of ...

How sperm crack the whip

... motility to the mechanism by which the sperm head delivers its genetic payload to the egg, he said. Such research could yield insight into some male infertility, said Clapham. Still-unidentified mutations in any of the four CatSper proteins ?all of which are involved in motility ?could underlie some forms ...

Georgia Tech accelerates drug discovery with new IBM supercomputing cluster

...ltra-dense and easy to manage. "AMD64 technology delivers the processing power needed to run some of the most demanding supercomputers, without sacrificing performance-per-watt efficiencies," said Kevin Knox, vice president, Worldwide Commercial Business, AMD. "By working closely with IBM on their AMD Opter...

Weizmann Institute suggests that immune cells help to maintain cognition and brain cell renewal

...bserves certain memory functions. But how the body delivers the message instructing the brain to step up its formation of new cells is yet unknown. The central nervous system (CNS), comprising the brain and spinal cord, has been considered for a long time as "a forbidden city", in which the immune system is ...

Scientists a step closer to protecting world's most important crop

...gus. Until now it's not been known how the fungus delivers that weaponry, but researchers from the School of Biosciences have identified a single gene that appears to be important in the process. Professor Nick Talbot, who led the research, said: "We have identified a secretion system that we think is respo...

Infection 'alarm' yields clues to immune system behavior

...kins researchers have learned how a common protein delivers its warning message to cells when an infectious agent invades the body. The findings are important because this biological intruder alarm causes the body's immune system to leap into action to fight the infection. Learning more about how this process...

Cellular scale drug delivery from the inside out

...ent methods to control whether or not the particle delivers its pharmaceutical payload. "First, the nanospheres are only about 200 nanometers in diameter, roughly the size of a virus, so they won't trigger an immune response in the body," Lin said. "They're also biocompatible so they can be readily absorbe...

Sleeping sickness parasite shows how cells divide their insides

...plex, a membrane compartment in the cytoplasm that delivers newly-made proteins to different membranes in the cell. "Basal bodies in particular and centrosomes in general have been implicated in the biogenesis of a number of membrane-bound organelles," said Warren. "It prompted us to study further their role...
