Snapin: A protein with therapy potential for autism

... the binding between the cypin and snapin. This is easier to design and cypin can still function with the other proteins it binds to." Firestein's goal is to build "a core pathway of dendric branching" ?a sequence of steps, each affecting the next, with cypin at the center. "Our pathway says cypin does thi...

Bacteria are key to 'green' plastics, drugs

...inate," said San. "The implementation was actually easier than we expected because the cells did the balancing themselves." Bennett and San said they will continue to refine the organism to produce higher yields and fewer byproducts. ...

Researchers devise new technique for creating human stem cells

...embryonic stem cells, which are more plentiful and easier to obtain than unfertilized human eggs. In the studies published in Science , the researchers combined human fibroblast cells with human embryonic stem cells in the presence of a detergent-like substance that caused the two cell types to fuse. The ...

New technique rapidly detects illness-causing bacteria

...plicating or "amplifying" the DNA makes a pathogen easier to detect. The new process starts with genetic material that is extracted from a food sample. This material, called ribosomal RNA (rRNA), is responsible for translating genetic information carried in DNA into proteins. Nugen designed the computer s...

MicroRNA tweaks protein that controls early heart development

..., providing scientists who study microRNAs with an easier way to really figure out what they do," Dr. Srivastava said. In addition to Dr. Srivastava and Dr. Zhao, UT Southwestern postdoctoral researcher in pediatrics Dr. Eva Samal also contributed to the research. ...

South Africa still debating how to tackle HIV/AIDS when 5 million are infected

...hat a new generation of drugs would be cheaper and easier to use, delegates at the 4,000-strong conference came to the defence of ARV drugs. Fatima Hassan of the AIDS law project at the University of Witwatersrand, was very critical of the govenment and said she thought there was "deliberate campaign again...

AIDS expert says global strategy needed to combat feminization of HIV/AIDS

...due to an immature genital whose mucosal lining is easier for the virus to penetrate; to hormonal factors, such as the use of birth control pills; and to a high incidence of sexually transmitted diseases, which inflame the female genital area and provide additional target cells for the virus to infect. Qui...

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

...e undergoing bone-marrow transplants. It is much easier to get approval for a new diagnostic test than a new drug. So the researchers estimate that it will take only two to three years to develop and validate the new test. "All the components are off-the-shelf," Wright adds, "so any one can put together o...

Modification of program enables prediction of gene transcription

... protein-coding exon? These kinds of questions are easier to answer now." ...

From a Few Wild Ancestors, a Citrus Cornucopia

... the diversity in the Citrus genome. This makes it easier to search for specific genes related to pest and pathogen resistance and to high flavonoid and nutrient levels.?/p> For their work, the researchers used 25 molecular markers, 13 of which they created, to help them track genetic similarities betwe...

'Gadonanotubes' greatly outperform existing MRI contrast agents

...s increase the sensitivity of the scans, making it easier for doctors to deliver a diagnosis. Gadolinium agents are the most effective agents and the most commonly used. In the future, the researchers hope to use existing methods of attaching disease-specific antibodies and peptides to gadonanotubes so the...

New technique could alter field of mouse genetics

...ble gene-transposing tool could make that job much easier and quicker. Xu and his colleagues at Fudan University in Shanghai, China, began their studies with a transposon called piggyBac. With the help of a partner enzyme, piggyBac can reliably and efficiently insert itself into the genomes of human and mo...

Virus uses tiny RNA to evade the immune system

... the belief that its diminutive size would make it easier to understand the functions of any microRNAs they found. SV40 is a relatively harmless monkey virus that can cause kidney infections in its natural simian host. In rodents, however, it can cause cancer. Although the SV40 genome has been found in som...

Promising therapies for haemophilia & heart disease

... to be less frequent. "This promises to be a much easier and more effective approach for sufferers, particularly children," said Wagner. Wagner went on to report, "Blood clotting is an intricately balanced process. Blood clots in the heart or brain can result in a heart attack or stroke. Our studies in mo...

LIAI scientists make major finding on potential smallpox treatment

...used new techniques that we developed that made it easier to identify and isolate antibodies from the blood of immunized humans. Then we carefully screened for the antibodies that fight the smallpox virus," he said. The researchers then tested their findings by creating a batch of the anti-H3 protein antib...

NHGRI expands effort to revolutionize sequencing technologies

...erences between these modified nucleotides will be easier to detect, producing clean sequencing data. Bhubaneswar (Bud) Mishra, Ph.D., New York University, New York. $585,000 (2 years) "Haplotype Sequencing Via Single Molecule Hybridization" Investigators from this group will hybridize short DNA probes to...

UW scientists report a new method to speed bird flu vaccine production

...mproved "reverse genetics" technique that makes it easier to make a seed virus in monkey kidney cells, which, like tiny factories, churn out millions of copies of the disarmed virus to be used to make vaccines. In nature, viruses commandeer a cell's reproductive machinery to make new virus particles, whic...

Reducing antibiotic use lowers rates of drug-resistant bacteria

...study. In essence, doctors can make their own jobs easier by prescribing antibiotics more judiciously, thus slowing the spread of superbugs. ...

Scientists map one of biology's critical light-sensing structures

...are easy to grow in the lab and their proteins are easier to purify and manipulate than plant proteins. Once isolated, the phytochrome was crystallized and its molecular structure was mapped using a beam of X-rays to develop a three-dimensional picture of the protein. That three-dimensional portrait, which...

Sperm stem cells closer to being like embryonic stem cells

...a green fluorescent protein, making the germ cells easier to identify when mixed with other cell types. "The rat testes contain other cells types in addition to stem cells," Dr. Hamra said. "If these other cells are included in the culture, they produce chemicals that block the ability of the stem cells t...
