Biomarkers may hone anti-aging therapies

... human tissue specimens -- brain, lung, heart, for example -- look for these changes and report back. "It will be interesting to see if the mitochondrial DNA mutations we've found are markers of aging in other tissues or if they are specific to tissues exposed to ultraviolet light." Either way, the newly i...

Anti-inflammatory drug's potentially deadly side effect found to be rare

...mized targeting techniques. "This drug is a good example of the potential of developing drugs with very specific biological targets in mind," Clifford says. "But this experience also reminds us that there are a lot of hidden icebergs in the ocean we're navigating, and we're going to bump up against those i...

UCR researchers design chip that can improve citrus varieties

...ciated with taste, acidic content and disease, for example ?the chip provides information useful to researchers for rectifying existing problems and making improvements to the fruit. The citrus array will be used to develop new diagnostic tools for the improvement of citrus agriculture and post-harvest frui...

Hepatitis C therapy: Inhibiting newly discovered microDNA molecule

...n virus, called target 5' NCR. This is the first example of an animal RNA that interacts with its target 5' NCR, and opens an interesting possibility that other viral 5' NCRs are similarly targeted by different miRNAs. ...

Evolution of 'irreducible complexity' explained

...lar methods to unravel the evolution of an elegant example of molecular complexity ?the specific partnership of the hormone aldosterone, which regulates behavior and kidney function, along with the receptor protein that allows the body's cells to respond to the hormone. They resurrected the ancestral recept...

Crucial site for endangered frogs and birds saved

... landmark for Colombian conservation, it is a fine example of international collaboration." In late December, Fundación ProAves learned of the impending sale of plots from the site for construction of vacation homes. It alerted the Alliance for Zero Extinction of the crisis, and in less than a month, ABC an...

Stem cell transplants improve recovery in animal models for stroke, cerebral palsy

...eliver a therapeutic benefit in multiple ways, for example by producing factors that limit tissue damage and stimulate repair, according to Dr. Gil Van Bokkelen, the company's chairman and chief executive officer. In addition, MultiStem TM cells can safely mature into a broad range of cell types and can be...

Evolution mystery: Spider venom and bacteria share same toxin

...ommon ancestor," Cordes said. "Aside from being an example of lateral transfer between very distantly related organisms, this study is an unusual example of using structural motifs in proteins to answer questions about common ancestry when gene sequences...

FDA approves first medical device using rutgers biomaterial

...s, The State University of New Jersey. "This is an example of a close and strong academic-industry interaction that led to a relatively fast entrance of the product into the medical market." Kohn pointed out that the technology was invented in 1997 and has progressed along a fast and efficient track to FDA ...

Liquid crystals show promise in controlling embryonic stem cells

... tissue. "This research is also significant as an example of our unique effort to integrate advanced materials engineering and embryonic stem cell research, an effort that will help accelerate the rate at which the benefits of stem-cell based therapies are brought to society," de Pablo adds. ...

Study reveals classic symbiotic relationship between ants, bacteria

...o fight the parasite. The phenomenon is a classic example of mutually beneficial symbiosis, and Currie views it as a model system with the potential to shed light on the way other organisms interact. Although the ants and their fungus gardens had been closely studied for dozens of years, Currie was the fir...

Scientists force viruses to evolve as better delivery vehicles for gene therapy

...bstrate or better able to catalyze a reaction, for example - or to make antibodies better binders against specific targets," said Schaffer, who also is an affiliate of the UC Berkeley wing of the California Institute for Quantitative Biomedical Research (QB3). "In the viral realm, this approach is essentiall...

Research updates 65-year-old genetic discovery

...ns and chimpanzees and existed throughout time--an example of balancing selection. Their findings were publis..."their explanation was wrong." Instead of being an example of balancing selection, the researchers conclude that both humans and chimpanzees have gene variants...

Report shows deforestation threatens Brazil's Pantanal

...d by the forests and other types of vegetation. An example is the hyacinth macaw, a species threatened with extinction, which depends on a tree commonly called 'manduvi' (Sterculia apetala) for shelter and reproduction. Without this specific tree, chances are that the hyacinth macaw will disappear. Accordin...

Unraveling the mysteries of poison

...lar protein synthesis procedures and looked at the example of poison from the north African scorpion Androctonus mauretanicus mauretanicus, to determine how bacterial potassium channels interact with toxins at an atomic level. The researchers first examined the electrophysiological characteristics of the "...

First demonstration of 'teaching' in non-human animals

...at some initial cost to itself, in order to set an example so that the other individual can learn more quickly. Professor Franks said: "We also believe that true teaching always involves feedback in both directions between the teacher and the pupil. In other words, the teacher provides information or guida...

Parts of the Caribbean and Central America are likely to have less summer rain

...occur. The Caribbean/Central-American region is an example where the models agree reasonably well. Neelin's research is federally funded by the National Science Foundation and the National Oceanic and Atmospheric Administration. In addition to analyzing the computer simulations, Neelin and his colleagues a...

Cracking the genetic code for control of gene expression

...read-outs of DNA sequence for several species, for example mouse, dog, cow and chicken, in the recent years. But without a code or 'grammar' to reveal the message behind the sequence, the genomic DNA is merely a list of millions and millions of base pairs, A's, C's, G's and T's one after the other. Based on...
