'Red Tide' Species Deadlier Than First Thought
2012-07-25 15:15:43

redOrbit Staff & Wire Reports - Your Universe Online A researcher at the University of Connecticut and his team have discovered that a species of tiny aquatic organism prominent in harmful algal blooms sometimes called "red tide" is even deadlier than first thought, with potential consequences for entire marine food chains. Professor Hans Dam along with his research group in the school's Department of Marine Sciences have discovered that the plankton species Alexandrium tamarense...

Sanford-Burnham researchers determine the first 3D structure of the botulinum neurotoxin, together with the protein bodyguard that guides it through the body–revealing weak spots that could be exploited to develop new counterterrorism measures. La Jolla, Calif. (PRWEB) February 23, 2012 Researchers at Sanford-Burnham Medical Research Institute (Sanford-Burnham) and the Medical School of Hannover in Germany recently discovered how the botulinum neurotoxin, a potential bioterrorism...

The most poisonous substance on Earth – already used medically in small doses to treat certain nerve disorders and facial wrinkles – could be re-engineered for an expanded role in helping millions of people with rheumatoid arthritis, asthma, psoriasis and other diseases, scientists are reporting. Their study appears in ACS' journal Biochemistry. Edwin Chapman and colleagues explain that toxins, or poisons, produced by Clostridium botulinum bacteria, cause of a rare but severe...

A slight change in molecular structure introduced by genetic engineering gives crop-protecting proteins called Bt toxins a new edge in overcoming resistance of certain pests, a UA-led team of researchers reports in Nature Biotechnology One of the most successful strategies in pest control is to endow crop plants with genes from the bacterium Bacillus thuringiensis, or Bt for short, which code for proteins that kill pests attempting to eat them. But insect pests are evolving resistance...

(Ivanhoe Newswire) -- Spider venom could hold the key to understanding how the body operates. Researchers have discovered a toxin from the American Funnel Web spider acts on T-type and N-type calcium channels. They say the toxin offers a new target for studying T-type channels, which play a role in congestive heart failure, hypertension, epilepsy and pain. The investigators, from the University of California at Riverside, purified the toxin and created a recombinant version. "If we can...

Discovery by California researchers described today at Biophysical Meeting in Baltimore Spider venom toxins are useful tools for exploring how ion channels operate in the body. These channels control the flow of ions across cell membranes, and are key components in a wide variety of biological processes and human diseases. A newly identified toxin from the American Funnel Web spider acts on T-type and N-type calcium channels, researchers from the University of California at Riverside have...

Bacteria often attack with toxins designed to hijack or even kill host cells. To avoid self-destruction, bacteria have ways of protecting themselves from their own toxins. Now, researchers at Washington University School of Medicine in St. Louis have described one of these protective mechanisms, potentially paving the way for new classes of antibiotics that cause the bacteria's toxins to turn on themselves. Scientists determined the structures of a toxin and its antitoxin in Streptococcus...
