Studies to find better ways to preserve human eggs, ovarian tissue under way

...nd out which is the best option: ovarian tissue or pure eggs. Also, a better way to preserve eggs – which last about 24 hours outside the body without preservation – would reduce the cost and logistical issues of coordinating donor eggs. “The long-term goal is organ banking,” says Dr. Song, because eve...

A cherry on top: Tart cherries may alter heart/diabetes factors

...eymour. "Previous research by other groups studied pure anthocyanin compounds rather than anthocyanin-containing whole foods, and they used concentrations of anthocyanins that would be very difficult if not impossible to obtain in the diet." He continues, "We are interested in a whole-foods approach, u...

Amphibians in losing race with environmental change

...oo rapidly. In the past, water was reasonably pure and clean. But increased "eutrophication" of freshwater ponds due to use of modern fertilizers and waste from grazing animals has led to higher rates of parasite infections, and chemical contamination of aquatic systems is also more common. Many...

Biodiesel study targets cleaner air, cleaner engines

... from Agriculture and Agri-Food Canada tested both pure and blended biodiesel, in which the renewable fuel is mixed with petroleum diesel. Evaluated blends had 5 percent and 20 percent biodiesel content, and were tested for engine horsepower and fuel efficiency. Environment Canada monitored exhaust emissi...

Researchers develop technique for bacteria crowd control

...tory. "Our results provide strong evidence for the pure hydrodynamic origin of collective swimming, rather than chemotactic mechanisms of pattern formation when microorganisms just follow gradients of a certain chemical, such as nutrient, Oxygen, or other" ...

... of nanocrystals measuring about 100 nanometers of pure HPPH, (2-devinyl-2-(1?hexyloxyethyl) pyropheophorbide), a photosensitizer currently in Phase I/II human clinical trials at RPCI for treating various types of cancer. The UB researchers found that the nanocrystals of HPPH were taken up by tumors in ...

Ethanol vehicles pose a significant risk to human health, study finds

...ran on fuel made primarily from ethanol instead of pure gasoline, the number of respiratory-related deaths and hospitalizations would likely increase, according to a new study by Stanford University atmospheric scientist Mark Z. Jacobson. His findings are published in the April 18 online edition of the jo...

Scientists unlock mystery of embryonic stem cell signaling pathway

Lower carbon dioxide emissions from coal-fueled power plants possible with technology development

...ated amine. The solution is then boiled to produce pure carbon dioxide. In Rochelle’s campus laboratory, he will work to improve this approach by using a chemical additive to increase the rate of carbon dioxide absorption into the solution, and assessing the overall capture process using computer mode...

Baby fish 'smell their way home'

Growth factor stimulates rapid extension of key motor neurons in brain

...n his laboratory, developed a new way of isolating pure populations of CSMN in culture and found that IGF-1 was a prime candidate for control over CSMN development. Using these purified neurons, they then showed that two ways of applying IGF-1 ?generally adding it to culture dishes or placing IGF-1-coa...

New engineered drug may offer prolonged arthritis relief

...cy dropped by a factor of about 20 compared to the pure drug. Further studies, however, suggested the fusion protein might do better in an arthritic joint, Shamji said. The researchers were surprised to find that the same inflammatory enzymes that destroy joint collagen also chew ELP from the original d...

PNAS study reveals why organs fail following massive trauma

... each immune cell type in the patients' blood into pure samples for study. Only when researchers compared pure samples of the same immune cell types (e.g. T cells to T cells) did meaningful patterns emerge. The ...

Biofuel cells without the bio cells

...is a self-powering sewage treatment plant. Using pure protein opens up the possibility of shrinking biofuel cells to power small electronic devices, Squier said. Whole-organism biofuel cells require engineers to design a space-adding membrane that prevents unwanted reactions between fuel, the charge-tra...

Highly concentrated botulinum preparation for cosmetic injections can result in severe illness

...use. Clinic staff had diluted a 100-µg vial of pure neurotoxin with diluent and drew up the resulting solution into syringes for clinical use. The physician working at the clinic administered 4 case-patients (including himself) 4 to 6 injections of this toxin solution in the facial area. All the pati...

Better sludge through metagenomics

...me sequence of Accumulibacter phosphatis without a pure culture of the organism, which, like most microbes, eludes laboratory culture. We expect that clues hidden in the genome will lead to domestication of this mysterious organism, enabling further studies of its habits and lifestyle. "The genome sequ...

Pure carbon nanotubes pass first in vivo test

... in the body. Nanotubes are hollow cylinders of pure carbon that measure just one nanometer in diameter ?about the same width as a strand of DNA. Nanotubes have unique chemical and optical properties, and they have attracted intense interest from biomedical researchers. "The early results are promis...

When nerve cells can't make contact

...ane of the receiving cell." What was initially a pure basic research project has consequently acquired direct relevance to medicine. "What we see in our neuroligin mutants is a more intensified form of the malfunction that occurs in the brain of autistic people," says Brose. "I believe that autism is a ...

With record resolution and sensitivity, tool images how life organizes in a cell membrane

...tivity is important because cell membranes are not pure materials. ''We're looking at mixtures of things, and we want to be able to say that we've got one molecule in 20 of type A mixed in with type B, or something like that,'' Boxer said. This world is flat-sometimes ''Imagine how a cell could divide...
