Many countries still selling consumer paints with dangerous levels of lead

Although lead content in paint has been restricted in the United States since 1978, University of Cincinnati (UC) environmental health researchers say in major countries from three continents there is still widespread failure to acknowledge its danger and companies continue to sell consumer paints that contain dangerous levels of lead.

Accidental childhood poisonings mostly due to medicines

More than two-thirds of all emergency department visits for childhood poisoning involve prescription and over-the-counter medications, more than twice the rate of poisonings from consumer products, reports a new study from the Centers for Disease Control and Prevention (CDC).

Potential new treatment for Alzheimer’s

Indeed, these carriers tend to develop the disease later than others, but when that happens, it progresses more rapidly and does not respond to medication. Therefore, the bottom line is that carriers of the mutated gene have a greater risk than others for disease progression.

Breakthrough in combating adverse side-effects associated with quinine

Discovered back in the 1600s quinine was the first effective treatment in the fight against malaria - and it continues to be a commonly used treatment against this devastating disease. But the drug is associated with a long list of side effects which can range from sickness and headaches to blindness, deafness and in rare cases death - and until now no one knew why.

Intervention strategies to curb spread of pandemic flu

Mathematicians, biostaticians and public health officials from Canada, Mexico and the United States will gather at Arizona State University this week to focus on understanding, possibly mitigating the spread of the H1N1 flu virus. They are planning to take up the challenge of proposing science-based strategies that can slow the spread of pandemic flu.

New discovery on how botulism paralyzes nerve cells

New structures of a botulism toxin interacting with a mimic of the nerve-cell protein it destroys suggest new ways to block this often-fatal interaction. Indeed, the mimic molecules have such high affinity for the toxin and bind to it so tightly that they themselves could possibly serve as anti-toxin drugs with further modification, the researchers said.

Tamed virus wipes out cancer safely

Cancer Research UK scientists have tamed a virus so that it attacks and destroys cancer cells but does not harm healthy cells, according to a paper published in PLoS Pathogens, today.

Bacteria of the Yersinia genus possess a unique protein thermometer

Bacteria are experts at adaptation: as soon as they have infected an organism, they adapt their metabolism to that of their host and produce substances which protect them from the body's immune defences. How they do this is still unknown in the case of many types of bacteria.

Salmonella’s weakness for sugar predicts its downfall

For the first time UK scientists have shown what the food poisoning bug Salmonella feeds on to survive as it causes infection: glucose.

Banned toxic chemicals in Australian everyday products

Australia's leading consumer advocacy organisation CHOICE says an investigation has revealed that many chemicals freely available in Australia are no longer registered in Europe because of safety concerns.

New initiative to ensure the safe use of methadone

The U.S. Substance Abuse and Mental Health Services Administration (SAMHSA) and the U.S. Food and Drug Administration (FDA) has launched an initiative to help ensure the safe use of methadone.

New understanding of 3D structure of bacterial secretion proteins

New details of the composition and structure of a needlelike protein complex on the surface of certain bacteria may help scientists develop new strategies to thwart infection.

Key genetic mechanism a potential key to new class of antibiotics

Researchers have determined the structure of a key genetic mechanism at work in bacteria, including some that are deadly to humans, in an important step toward the design of a new class of antibiotics, according to an accelerated publication that appeared online today as a "paper of the week" in the Journal of Biological Chemistry.

Canadian experts on irritable bowel syndrome

While more than six per cent of Canadians suffer from this troublesome disease - characterized by on-going abdominal pain, discomfort, bloating, and severe bouts of either diarrhoea or constipation - most Canadians, including many physicians, know little about it.

Health problems associated with Chinese slimming capsules

Taking herbal food supplements is certainly not free of risk. Since 2005, the poison emergency centers in the German cities of Freiburg and Gottingen have registered a total of 17 patients with health problems after taking Chinese slimming capsules.

New understanding on how probiotics can prevent disease

Using probiotics successfully against a number of animal diseases has helped scientists from University College Cork, Ireland to understand some of the ways in which they work, which could lead to them using probiotics to prevent and even to treat human diseases.

Stem cell infusion and hyperbaric oxygen treatment improve islet function in diabetes

A study to determine if patients with type 2 diabetes can benefit from a combination of autologous (patient self-donated) stem cell infusions (ASC) and hyperbaric (above the normal air pressure of ) oxygen treatment (HBO) before and after ASC has found "significant benefits" in terms of "improvements in glycemic control" along with "reduced insulin requirements."

Space-grown bacteria help explain Salmonella illness

Salmonella bacteria research from two recent NASA space missions discovered key elements of the bacteria's disease-causing potential that hold promise for improving ways to fight food-borne infections on Earth.

Researchers probe mechanisms of infection

A newly discovered receptor in a strain of Escherichia coli might help explain why people often get sicker when they're stressed.

New protein identified in bacterial arsenal

Nearly a billion years ago, bacteria evolved an insidious means of infecting their hosts - a syringe-like mechanism able to inject cells with stealthy hijacker molecules. These molecules, called virulence factors, play a sophisticated game of mimicry, imitating many of the cells' normal activities but ultimately co-opting them to serve the bacteria's needs.
