Gene therapy to lower blood pressure just enough

...angerously low levels, said O'Malley. Obviously, a method of controlling the gene and the amount of ANP a cell makes was needed. The special viral vector developed by O'Malley and his colleagues combines a special kind of adenovirus altered so it does not produce disease connected to a gene regulatory syst...

New technique rapidly detects illness-causing bacteria

...r increasing the sensitivity of the analysis. The method may help researchers and companies that are in the...rs. Promising early results suggest the sensitive method could detect fewer than 100 cells of a pathogen in just half an hour. Nugen's software also compare...

A novel method to measure circadian cycles

...rt in the open-access journal PLoS Biology a new method to measure circadian cycles in mammalian cells cul...sleep habits. The researchers point out that their method can expose differences in circadian rhythms; it does not, however, directly measure the signal from ...

A slight difference and significant similarities

...arly Edition, September 19). The scientists used a method developed at the Institute to identify substances in plants. The researchers compared genetically modified Desiree potatoes, which have a very high level of the polysaccharide inulin, with five conventional varieties. Inulin is a sugar in the class ...

MicroRNA tweaks protein that controls early heart development

...ivastava's lab at UT Southwestern, developed a new method to predict targets for vertebrate microRNAs based ...e genome for potential microRNA targets. "If this method of predicting targets turns out to be correct and specific, I think it will go a long way to opening...

Researchers create infectious hepatitis C virus in a test tube

...of HCV that they can observe in cell cultures. The method developed by Rice and his colleagues, including sc..., Ph.D., a postdoctoral fellow in Rice's lab. "Our method replicates and produces virus particles that can infect new cells, initiating replication in them an...

Rensselaer researchers develop approach that predicts protein separation behavior

... Rensselaer Polytechnic Institute have developed a method to predict protein separation behavior directly from protein structure. This new multi-scale protein modeling approach may reduce the time it takes to bring pharmaceuticals to market and may have significant implications for an array of biotechnology...

Quantum dots provide a faster, more sensitive method for detecting respiratory viral infections

...es have joined forces to create an early detection method for a respiratory virus that is the most common ca...postponing effective treatment. The new, high-tech method uses multi-colored, microscopic fluorescent beads, called quantum dots, which bind to molecular stru...

Sleeping beauty plays a significant role in identifying cancer genes

New imaging technology shown to detect pancreatic inflammation in type 1 diabetes

... and full-blown diabetes. Today, the only accurate method for detecting the progression or regression of ins... can, at least in mice, use a non-invasive imaging method to predict at a very early time whether a drug will stop the progression of diabetes or not. In fact...

York scientists warn of dramatic impact of climate change on Africa

... to climate change. Dr Lovett added: "We needed a method that would help fill in gaps in knowledge. The technique we used is called a genetic algorithm because it works in a similar way to the effect of evolution on chromosomes ?the programme combines different variables in lots of different ways and the b...

UF researchers kill resistant bugs one bandage at a time

...m there." A patent is pending on the researchers' method of chemically bonding the substance to fabrics and other materials. This method allows the substance to be efficiently mass produced and permanently adhered to wound dressings or r...

Can two killers make a cure?

...s to the lungs far more efficiently than any other method developed so far. And while the idea of combining ... opposition from a fearful public will prevent the method ever being used. Another problem with Kobinger's approach is that patients will require repeated tre...

UQ researcher tracking key to healing the brain

...a haystack," Dr Rietze said. "The tried and true method is to look for particular markers on the outside of the cell, but this is a long and laborious process. "What we are doing is looking at a distinguishing attribute of stem cells, which is that they are relatively quiescent, or don't divide much in ...

Hunt for human genes involved in cell division under way

... division is regulated. The scientists will use a method called 'RNA interference (RNAi)' where chemically synthesized RNA molecules are used to target and silence each human gene. About 22,000 genes will be suppressed and their impact on cell division monitored by live cell microscopy to understand each g...

Unweaving amyloid fibers to solve prion puzzles

...s of yeast. Rather than develop a single high-tech method for solving the amyloid structure, he instead used a combination of low resolution tools to analyze varieties of prion strains and piece together the puzzle of how amyloids form. "We now have an overall picture of how prions join together to form th...
