FDA sees nanotech challenges in every product category it regulates

...inflation—making sure that FDA has the capacity to safely manage nanotechnology must be the shared responsibility of Congress and our political leaders,” argued Rejeski. “The agency must be ‘nano-ready’ for the products on the market today and able to deal with the more advanced nanotechnology applications ...

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

...or, has developed cryoprotectants that can be used safely in higher doses as well as agents to help protect tissue during the ultra-rapid process of de-vitrification. “People use low concentrations of cryoprotection because they are toxic,” he says. “The problem is, if you use lower concentrations, you ...

UCF nanoparticle offers promise for treating glaucoma

...llions of people worldwide. “The nanoparticle can safely get past the blood-brain barrier making it an effective non-toxic tool for drug delivery,” said Sudipta Seal, an engineering professor with appointments in UCF’s Advanced Materials Processing and Analysis Center and the Nanoscience Technology Center....

Mule deer moms rescue other fawns

...aker tended to withdraw right away and then stayed safely outside that distance. The behaviour of mule deer defies traditional explanations that parental care, kin selection or reciprocity play a part in the defence of fawns other than their own. But while the study's findings seem to point to mule deer ...

Machine preservation may promote more organ sharing

...neys on a portable pump, preservation times can be safely extended to permit more time for sharing organs across the country," said Robert Stratta, M.D., lead researcher of the study, which is reported in the May issue of the Journal of the American College of Surgeons. In addition, Stratta said, the pum...

NIAID DNA vaccine for H5N1 avian influenza enters human trial

Neural bottleneck found that thwarts multi-tasking

Many people think they can safely drive while talking on their cell phones. Vanderbilt neuroscientists Paul E. Dux and René Marois have found that when it comes to handling two things at once, your brain, while fast, isn't that fast. "Why is it that with our incredibly complex and...

Natural polyester makes new sutures stronger, safer

... the human body produces naturally, so they can be safely absorbed once the wound is healed. They are also 30 percent stronger than sutures now used and very flexible, making them easier for surgeons to work with. The sutures were developed by Tepha, Inc., a Cambridge company that hopes to use the same m...

The research aimed to explore restaurant dishwashing conditions, but Pascall explained that homeowners can benefit from the findings, too. "Leaving food on eating utensils and dishes could easily cause...

One-of-a-kind imaging probe reveals secrets useful for drug discovery

...e something the walking stick uses to enable it to safely store the toxic material in the insect's gland until it is ready for use as a venom, to improve the properties of the spray or some other reason we haven't yet considered. It's the kind of thing that may provide hints about drug discovery in future."...

Gene signature assesses breast cancer outcomes

Studies look at how genes affect antipsychotic drug response

...re they are appropriately monitored and treated as safely as possible. "Understanding risperidone pharmacogenetics and whether some individuals are at a higher risk for side effects is an important step in this process," he said. Risperidone is widely prescribed to treat bipolar disorder in children, ac...

Report calls for improved monoclonal antibodies against solid tumors

...able to create monoclonal antibodies that could be safely used in humans, eight monoclonal antibodies have been approved for use in clinical treatments to trigger immune responses to cancer cells, modulate cancer cell growth, and deliver drugs to cancer cells. Of these, only three are used on solid tumors. ...

Ferns provide model for tiny motors powered by evaporation

...um remained closed like a fist, storing the spores safely inside. But when the water in the outer wall evaporated, it caused the sporangium to unfurl and eject the spores into the environment. The researchers examined some fern leaves under a microscope. They found that when exposed to light or heat or an...

Gene therapy for hereditary lung disease advances

...cs Institute. "We found that we can use this agent safely and we also saw evidence in the patients' blood that the higher doses successfully introduced the vector DNA. In one patient we saw evidence for a very brief period that some of the alpha-1 protein was being produced, but not at a high enough level t...

Cell wall of pneumonia bacteria can cause brain and heart damage

...of cell wall suggests that it might be possible to safely pre-treat people infected with S. pneumoniae with a drug that blocks PAF before we administer antibiotics," Tuomanen said. "This might protect the heart from the build-up of cell wall fragments released from bacteria killed by the antibiotic." Tuo...

Vaccine combined with short-term postexposure antibiotics protects monkeys from inhalational anthrax
