Researchers develop new ultrasensitive assay to detect most poisonous substance known
Scientists at City of Hope and the California Department of Public Health have developed a new ultrasensitive assay to detect botulinum neurotoxin. view more (2008-05-01)
New wrinkle in Botox treatment could lead to lower doses, better safety
There may soon be a better way to fight unsightly wrinkles. Researchers have discovered a novel way to increase the potency of botulinum neurotoxin treatments - commonly known as Botox - that they say could one day allow patients to receive the injections less frequently while maintaining or even... view more (2006-04-06)
Newly discovered small molecules
According to the study, these activators bind to specific sites on the neurotoxin protein, increasing protease activity and enhancing the toxin's effect. view more (2006-03-15)
E. coli playing the role of cobra
Moscow researchers have solved the most challenging problem: they made E. coli synthesize one of the most toxic elements of cobra's poison. It was no simpler a task than keeping a terrarium. The scientists' efforts were supported by the Russian Foundation for Basic Research and INTAS. Natural... view more (2004-05-07)
Scientists Determine Drug Target for the Most Potent Botulinum Neurotoxin
Botulinum neurotoxin -- responsible for the deadly food poisoning disease botulism and for the beneficial effects of smoothing out facial wrinkles - can also be used as a dreaded biological weapon. view more (2008-04-30)
Botulism study could lead to new vaccines and treatments to counter bioterrorist attacks
Of all the weapons in the bioterrorist arsenal, none is as potent as botulinum neurotoxin, which causes botulism-a potentially fatal disease with symptoms that include severe paralysis of the limbs and respiratory muscles. view more (2006-12-14)
Hotspots of mercury contamination identified in eastern North America
A US and Canadian research team surveying mercury contamination in fish and birds in the northeastern United States and southeastern Canada has identified five "hotspots" where concentrations of the element exceed those established for human or wildlife health. view more (2007-01-03)
Scripps research scientists: Compounds show significant promise against potential bioweapon toxins
Because of the high cost and limited applicability of currently available treatments, the newly identified compounds have the potential to fill the existing therapy gap and to provide protection against a bioterrorism attack using the toxin. view more (2007-02-06)
Very long term effects of Botox still unknown
The use of botulinum toxin for facial cosmetic enhancement has established its new image as a glamour drug, but its unlicensed use is increasing dramatically for certain conditions, ahead of clear scientific evidence. Although negative side effects are few, its very long term effects are still... view more (2002-11-20)
Molecular structure reveals how botulinum toxin attaches to nerve cells
Botulism is a life-threatening disease caused by exposure to botulinum neurotoxins, which are among the most potent toxins known. These neurotoxins are produced by Clostridium botulinum, a bacterium found in soil and food. view more (2006-12-14)
Seeing a neurotoxin's deadly grip
Two Howard Hughes Medical Institute research teams working independently have discovered new information about how the botulinum neurotoxin shuts down neurons with deadly efficiency. view more (2006-12-14)
New Tools Developed for Studying Neurodegenerative Brain Disorders
Penn State researchers have created an elegantly simple model of an axon-the extension of a neuron that communicates with other neurons-and have used this model to reproduce a change in the axon's shape that is characteristic of neurodegenerative disorders such as Alzheimer's and Parkinson's... view more (2006-03-22)
Ready meals need proper handling at home to prevent illness
Growing consumer appetite for ready-to-eat meals with a minimal preparation time and few preservatives has led to increased production and sales of chilled ready meals. Although the food industry has control measures in place to prevent growth of food poisoning organisms, consumers need to handle... view more (2002-02-11)
Botox for newborns
Botulinum toxin, also called Botox, is best known as one of the most commonly used molecules to reduce wrinkles. It is also known as one of the most poisonous naturally occurring substances. view more (2008-03-18)
Tetanus toxin found to have therapeutic properties
A team of researchers from the Department of Biochemistry and Molecular Biology and the Institute of Neuroscience at the Universitat Autònoma de Barcelona has discovered that tetanus toxin, which causes tetanus, could be extremely useful as a therapy against psychological disorders... view more (2005-06-15)
Dental chair a possible source of neurotoxic mercury waste
Mercury is a large component of dental fillings, but it is not believed to pose immediate health risks in that form. When exposed to sulfate-reducing bacteria, however, mercury undergoes a chemical change and becomes methylated, making it a potent, ingestible neurotoxin. view more (2008-03-27)
Study suggests loss of 2 types of neurons -- not just 1 -- triggers Parkinson's symptoms
New evidence indicates that the loss of two types of brain cells--not just one as previously thought--may trigger the onset of symptoms associated with Parkinson's disease. view more (2007-08-14)
Researcher finds new use for botox
Botox, used by Hollywood stars to smooth out facial wrinkles, is playing an important role in UQ research to understand how nerve cells communicate with each other. view more (2005-09-22)
Waterborne carbon increases threat of environmental mercury
Mercury is a potent neurotoxin and a worrisome environmental contaminant, but the severity of its threat appears to depend on what else is in the water. view more (2007-12-11)
Implanting dopamine generators in brain cells obtains improvement in Parkinson's in monkeys
Implanting dopamine generators (dopaminergics) in brain cells has produced improvement in the symptoms in Parkinson's, according to the results of tests carried out with monkeys by the Navarra University Hospital, led by Dr María Rosario Luquin Piudo, neurologist at the Hospital and at the... view more (2007-05-17)
Discovery of post-stimulus activated release implies new mechanisms for dopamine release
The neurotransmitter dopamine continues to be released for nearly an hour after neurons are stimulated, suggesting the existence of secondary mechanisms that allow for sustained availability of dopamine in different regions of the brain including areas critical for memory consolidation, drug... view more (2006-10-16)
Scientists reveal how deadly toxin hijacks cells
Scientists have pinpointed exactly how botulinum neurotoxin A-a potential agent of biological warfare and one of the most lethal toxins known to man-is able to sneak into cells. view more (2006-03-17)
Highly concentrated botulinum preparation for cosmetic injections can result in severe illness
An examination of 4 cases of botulism following cosmetic injections to the face indicates that the adults received a highly concentrated, unlicensed preparation that resulted in toxin levels up to 40 times the estimated human lethal dose. view more (2006-11-22)
Gold nanoparticles help detect a toxic metal -- mercury
With gold nanoparticles, DNA and some smart chemistry as their tools, scientists at Northwestern University have developed a simple "litmus test" for mercury that eventually could be used for on-the-spot environmental monitoring of bodies of water, such as rivers, streams, lakes and... view more (2007-04-27)
Transplanted brain cells hold promise for Parkinson's disease
Transplanted neural stem cells hold promise for reducing the destruction of dopaminergic cells that occurs in Parkinson's disease and for replacing cells lost to the disease, scientists say. view more (2006-12-05)
