Virginia Bioinformatics Institutes launches microbial database

...ment of Energy (DOE) Joint Genome Institute (JGI), successfully completed the genome sequences of the pathogens in 2004. The database can be accessed by visiting http://phytophthora.vbi.vt.edu ...

Genetically engineered mosquitoes show resistance to dengue fever virus

Researchers have successfully created a genetically engineered mosquito that shows a high level of resistance against the most prevalent type of dengue fever virus, providing a powerful weapon against a disease that infects 50 million people each year. Anthony James, a UC Irvine...

Heparin prepared synthetically could replace animal-derived drug

...grams. Rensselaer and UNC-Chapel Hill researchers successfully synthesized hundreds of milligrams of heparin by developing a large-scale process involving engineered enzymes and co-factor recycling. The new, scaleable process can be applied to synthesize other heparin-based structures that regulate cell growth a...

Contaminants linked to sturgeon decline in Columbia river

...ottom-dwelling white sturgeon rarely navigate dams successfully making it difficult for them to expand their habitat or access oceanic food sources. Schreck and Feist studied white sturgeon from three reservoirs along the Columbia River and from areas downstream of Bonneville, the last dam on the river in its pa...

Researchers use mass spectrometry to detect norovirus particles

...his purpose. Using a two-step process, researchers successfully separated, purified and concentrated a norovirus surrogate from a clinical sample within a few hours. Nanospray mass spectrometry was used to demonstrate the feasibility of detecting norovirus particles in the purified concentrates. Human norovirus ...

Engineered heart tissue offers insights into irregular heartbeats, defibrillator failure

...n an attempt to terminate this wave." The pulses successfully halted the wave 80 percent of the time, they reported. In the remaining cases, however, the pulses converted the single wave into multiple waves that continued to activate the cardiac cells at an accelerated rate. "In other words, instead of termina...

Ancient ants arose 140-168 million years ago

...his purpose. Using a two-step process, researchers successfully separated, purified and concentrated a norovirus surrogate from a clinical sample within a few hours. Nanospray mass spectrometry was used to demonstrate the feasibility of detecting norovirus particles in the purified concentrates. Human norovirus ...

US woman gives birth to baby from world's first frozen donor egg bank

...Kentucky and Phoenix, Arizona. The technology to successfully freeze and thaw donor sperm for infertile couples ... available for decades. However, the technology to successfully freeze women's eggs did not exist until recently, prompting Cryo Eggs International (CEI) to open it...

Manchester scientists create new bio-gel for 3D cell culture

...ve medicine." Dr Ulijn and his collaborators have successfully cultured cartilage cells using the gel. They found that both the properties of the gels formed and the cell response to the gels could be controlled by using different combinations of di-peptides. The team recently received a £630k award from EPSRC ...

New method for identifying microbes

...gion contains enough unique genetic information to successfully identify all community members down to the genus level, and most to the species level as well. "Sequencing is expensive, so the shorter the section you can sequence and still get useful information, the better," van der Lelie said. "In fact, because...

Nanopore method could revolutionize genome sequencing

...y think it is only a matter of time before someone successfully assembles the device. The nanopore and the electrodes have been made separately, and although it is technically challenging to bring them together, the field is advancing so rapidly that they think it should be possible in the near future. In add...

Wisconsin scientists grow two new stem cell lines in animal cell-free culture

...or of anatomy who seven years ago was the first to successfully grow human embryonic stem cells in the lab. "This ... cell culture medium on new lines, Thomson's group successfully cultured four existing stem cell lines in the new culture mix for extended periods, and their chromo...

'Scent of a woman' tells male redback spiders to find a mate

... the female -- that prevents any future males from successfully fertilizing her eggs, meaning that males have to mate with a virgin to maximize their reproductive success. "On the one hand, they want to provision themselves to survive this trip," says Andrade. "On the other hand, they have to develop quickly so ...

Salmon go veggie to save wild fish stocks

...DHA (docosahexaenoic acid), the fish can be reared successfully on these alternate diets", says Professor Brauner, "As aquaculture continues to expand, fish oil will become increasingly more expensive because it is a limited resource, and canola oil will not only be more sustainable as a lipid source, but also wi...

Plastic surgeons countdown first full facial transplantation

...ir kind, U.S. plastic surgeons demonstrated how to successfully complete a full facial tissue transplantation from...ddition, it takes multiple grafts and surgeries to successfully reconstruct the entire face. Many patients are left with a patchy, unfavorable appearance, includin...

How low can you go? Ants learn to limbo

...the height of horizontal barriers so that they can successfully crawl under it without slowing down. Tobias Seidl will be presenting his latest research findings at the Annual Meeting for the Society for Experimental Biology on Tuesday 4th April. Desert ants generally scurry around at high speeds whilst foraging...

Heat-shock protein vaccine reduces alveolar bone loss

...lymerase chain-reaction indicated that the vaccine successfully eradicated the multiple pathogenic species. The researchers concluded that P. gingivalis HSP60 could potentially be developed as a vaccine to inhibit periodontal disease induced by multiple pathogenic bacteria. ...

Cancer virus protein needed for successful infection

...ect ?suggests that HTLV-1 needs the p13 protein to successfully infect the body and reproduce. The research, published in the April 1 issue of the Journal of Virology, was led by scientists with The Ohio State University Cancer Program and OSU College of Veterinary Medicine. "It is important to understand the...

New device could cut chemotherapy deaths

...Chemical Engineering, over the past few years, has successfully gone through preliminary laboratory trials. The first clinical trials on volunteer patients with ovarian cancer in Avon, Somerset and Wiltshire could begin in the next few years and, if successful, the technology could be put into general use. The r...

U of MN uses robotic surgery techniques in cardiac cell therapy research

...they engrafted in the pig hearts. The cells were successfully transplanted in six of seven cases. Subsequent MRI studies showed that the cells took hold in the heart and function improved. The team used a combination of skeletal myoblasts, or cells that give rise to muscle, and bone-marrow derived cells. Bot...
