Dendritic cells play central role in regulation of acetaminophen's toxicity

NYU School of Medicine researchers have discovered that dendritic cells in the liver have a protective role against the toxicity of acetaminophen, the widely used over-the-counter pain reliever and fever reducer for adults and children.

Cell's reserve fighting force shrinks with age: Study

When the body fights oxidative damage, it calls up a reservist enzyme that protects cells - but only if those cells are relatively young, a study has found.

Biophysicists discover how to turn body's own resistance to radiation treatment on and off

Radiation can make cancer cells resistant to radio- and chemotherapy. University of Oslo researchers have now figured out how resistance can be switched on and off.

Babies, toddlers with congenital heart disease more likely to have harmful toxins after surgery

Babies and toddlers with congenital heart disease are at an increased risk of having harmful toxins in their blood, particularly following surgery, according to research by a team at Imperial College London.

Early-morning cigarette smokers more likely to develop lung, head and neck cancers

Two new studies have found that smokers who tend to take their first cigarette soon after they wake up in the morning may have a higher risk of developing lung and head and neck cancers than smokers who refrain from lighting up right away.

Insight into how bacterial toxins cause human diseases may help improve treatment

A better understanding of how bacterial toxins cause common human diseases may lead to their improved treatment and prevention according to a paper just published by Irish and US scientists in Nature Reviews Microbiology.

Hospital acquired Clostridium difficile bug defense system identified

American researchers have discovered the process by which the cells in the gut fight off toxins produced by a hospital bug - Clostridium difficile. Writing in Nature Medicine, they showed how a chemical - GSNO - deactivated a toxin from Clostridium difficile which causes inflammation and diarrhea. They hope to use their findings to develop a treatment for C. difficile.

No effective treatment yet for acute lung injury

Patients can essentially drown in their own fluids when trauma and infection prompt blood vessels to leak, flooding millions of air sacs in their lungs.

Research uncovers natural defense mechanism that inactivates C. diff toxins

Groundbreaking research encompassing Case Western Reserve University School of Medicine and University Hospitals Case Medical Center, has uncovered a natural defense mechanism that is capable of inactivating the toxin that spreads Clostridium difficile, or C. diff, an increasingly common bacterial infection in hospitals and long-term care settings.

Scientists discover key defense mechanism against C. difficile infection

Researchers have discovered a key mechanism used by intestinal cells to defend themselves against one of the world's most common hospital-acquired bacterial infections - a mechanism they think they can exploit to produce a therapy to protect against the effects of the antibiotic-resistant bacteria.

New CDI therapeutic approach may offer treatment for other bacterial diseases

Researchers at the David Geffen School of Medicine at UCLA and the University of Texas Medical Branch at Galveston have discovered a molecular process by which the body can defend against the effects of Clostridium difficile infection (CDI), pointing the way to a promising new approach for treating an intestinal disease that has become more common, more severe and harder to cure in recent years.

Study shows how certain woodrats put themselves on diet to avoid poisoning

Life is tough for woodrats in deserts of the U.S. Southwest. There are few plants for food, and those plants produce poison to deter rodents, insects and other animals. A new University of Utah study shows how certain woodrats put themselves on a diet to avoid poisoning: They sample a smorgasbord of toxic plants, eat smaller meals, increase time between meals and drink more water if it is available.

Smoking first thing in the morning ‘ups’ cancer stakes

Scientists have found that people who need a cigarette within the first half hour of waking up are at a higher risk for lung, head and neck cancers. Actually this indicates a higher nicotine addiction.
