New approach could overcome large immunosuppressive tumors

Harnessing the body's own immune system to destroy tumors is a tantalizing prospect that has yet to realize its full potential. However, a new advance from MIT may bring this strategy, known as cancer immunotherapy, closer to becoming reality.

Computer-based tools may help clarify potential health risks from food contaminants

When feeds are contaminated with potentially health-damaging substances, such as per- and polyfluorinated alkyl substances (PFAS)/per- and polyfluorinated chemicals (PFC) from the environment, these substances can be transfered into foods such as meat, milk and eggs.

IIVS releases technical training video on non-animal testing methods in laboratories

Funded by a grant from the European Partnership for Alternative Approaches to Animal Testing, the Institute for In Vitro Sciences, Inc. has released a technical training video that describes a cell-based in vitro method for assessing phototoxicity - the potential for chemicals to cause damage after being exposed to light.

Pitt researchers show how repair protein finds structural errors in DNA

Researchers at the University of Pittsburgh School of Medicine and University of Pittsburgh Cancer Institute have demonstrated how Rad4, a protein involved in DNA repair, scans the DNA in a unique pattern of movement called "constrained motion" to efficiently find structural faults in DNA.

Exposure to e-cigarette vapour induces negligible or no oxidative damage to lung epithelial cells

E-cigarette vapour is much less harmful to lung cells than cigarette smoke. Lab tests show that, unlike tobacco smoke, which causes oxidative stress and cell death, e-cigarette vapour does not. Oxidative stress and cell death are driving factors in the development of many smoking-related diseases such as COPD and lung cancer.

Many migrant farmworkers have visual impairment but do not receive routine vision screening

Migrant farmworkers have substantial rates of near- and distant-vision problems, but three-fourths have never had a vision screening test, reports a study in the October issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Wolters Kluwer.
