Spider Venom Could Yield Eco-Friendly Insecticides

...al analysis. Funnel-web spider venom is a complex brew of more than 100 chemical compounds, most of which are toxic to insects, but not vertebrates. King is studying the molecular structures of the toxins that selectively target the nervous systems of insects to understand the toxins' mechanism of action...

Natural Killers Could Lead to New Hepatitis Treatments

...assages, or “sinusoids,?are filled with a witches' brew of nutrients, toxins, proteins, lipids and other chemicals. Thus, immune guardians that patrol the liver must tolerate many foreign molecules, yet respond readily to infection. “It wasn't clear how NKT cells survey (tissue), or even if they survey a...

Katrina floodwaters not as toxic to humans as previously thought, study says

...nts and refineries in the area, releasing a deadly brew containing toxic levels of benzene, hydrochloric acid and chlorine. Instead, high levels of bacteria and viruses were the biggest human threat, not exposure to chemicals, Pardue and his associates say. The researchers obtained 38 floodwater samples ...

Stanford snake venom study shows that certain cells may eliminate poison

...r. Such misery is produced by a veritable witches' brew of toxins in snake venom. It's long been thought that the body's own immune system, rather than reducing the symptoms, may make things worse. But now researchers at the Stanford University School of Medicine have shown that the immune system really...

Teasing out tissue from blood

...ys it is about to submit a patent application on a brew that turns the monocytes into pancreatic islet-like cells that produce insulin in response to high levels of glucose. "We now want to transplant these cultures into a diabetic mouse model," says Winnier, adding their results are being prepared for pu...

The biggest bug in gut discomfort

... to compartments called lysosomes, where an acidic brew of hydrolase enzymes chews it up. By monitoring endosomal marker proteins, the researchers could watch as C. jejuni infected a host cell, and was briefly cloaked in the early endosomal marker EEA-1, and then the late endosomal marker Lamp-1. Was C. j...

Ocean seep mollusks may share evolutionary history with other deep-sea creatures

...st. Although seep and vent fluids are a poisonous brew for most species, animals such as giant tube worms and the mollusks studied by Kiel and Little thrive with the help of the symbiotic bacteria. "If you can become adapted to living at these sites, you can make a very good living indeed," Little said. ...
