Nanoparticles that can slip through mucus barriers shown to protect against herpes infections

Johns Hopkins researchers say they have demonstrated, for the first time in animals, that nanoparticles can slip through mucus to deliver drugs directly to tissue surfaces in need of protection. The researchers used these mucus-penetrating particles (MPPs) to protect against vaginal herpes infections in mice and the goal is to create similar MPPs to deliver drugs that protect humans against sexually transmitted diseases or even treat cancer.

Structure of human P-glycoprotein in a moving 3D computer model

A picture is worth 1,000 words when it comes to understanding how things work, but 3D moving pictures are even better. That's especially true for scientists trying to stop cancer by better understanding the proteins that make some chemotherapies unsuccessful.

Researchers determine structure of MRN complex

Double-stranded breaks in cellular DNA can trigger tumorigenesis. Researchers from Ludwig-Maximilians-Universitaet (LMU) in Munich have now determined the structure of a protein involved in the repair and signaling of DNA double-strand breaks. The work throws new light on the origins of neurodegenerative diseases and certain tumor types.

Sucrose and menthol act independently to reduce coughing

Millions of Americans reach for their cough drops or syrup at the first sign of a cough. However, scientists are unsure if and how these popular remedies work. Now, new findings from the Monell Center suggest that sucrose and menthol, ingredients commonly regarded as flavorings in these preparations, each act independently to reduce coughing.

My Air, My Health Challenge to spur collaboration between health researchers and technologists

A competition to create a personal sensor system that measures air pollution and a person's physiological response to it will offer cash awards to finalists, federal officials announced today. The goal is to help researchers, communities, and physicians better understand the connection between air quality and health.

suPAR protein can serve as marker for blood poisoning

Blood poisoning is a serious problem in medical care. Research from Malmö University in Sweden now shows that the protein suPAR, which can be used for early detection of critical cases of sepsis, is found in saliva, which opens new potential for tracking diseases.

TAU researcher develops new antibodies to target and destroy cancer cells

Because cancer cells grow very quickly, chemotherapy is designed to target cells whose numbers grow rapidly. But this treatment comes with a heavy price - many healthy cells essential for body functions are also targeted and killed by the toxin. This dangerous side-effect has prompted researchers to seek better and more selective ways to kill cancer cells inside the body.

Link between high levels of PCB and distribution of abdominal fat

There is a correlation between high levels of the environmental toxin PCB and the distribution of body fat to the abdomen. This is shown in a new study published today in the scientific journal Obesity. Abdominal fat is already known to increase the risk of diabetes and high blood pressure, among other conditions.

New, more accurate test for paralytic shellfish poisons

For decades, U.S. fisheries have tested the algal toxin levels of shellfish caught for human consumption by processing a sample of the shellfish in a blender and injecting the resulting slurry into the abdomen of live mice, causing them to suffer seizures, paralysis, and death by suffocation.

Viewpoints: The promise and perils of prostate screening; Presidential candidates shy away from frank discussion of spending

After an exhaustive process, the U.S. Preventive Services Task Force has announced its final recommendation on PSA-based prostate cancer screening. It finds that the known harms of screening outweigh the potential benefits for men who have no cancer symptoms. It notes that all screening studies have demonstrated considerable harms associated with screening, but only one major study found evidence that screening saves lives -- and that study has some internal inconsistencies.
