Plasma medicine research highlights antibacterial effects and potential uses

As interest in the application of plasma medicine — the use of low-temperature plasma (LTP) created by an electrical discharge to address medical problems — continues to grow, so does the need for research advancements proving its capabilities and potential impacts on the health care industry.

In the Metabolomics Core Facility, vials filled with extracts of bodily fluid wait in an auto-sampler. Each sample will be passed through a chromatography system that sorts the complex sample into its constituents. Droplets of the separated sample are then misted into the mass spectrometer for analysis.IMAGE: PATRICK MANSELL

Listening to your gut: A powerful new tool on the microbiome and cell metabolism

Many aspects of our lives — not only the presence or absence of certain diseases, but conditions like obesity, sleep patterns, even mood — may be determined, to a surprising extent, by the microbes living inside of us.

Persistent environmental contaminant changes the gut microbiome of mice

An industrial chemical — phased out since 2002, but previously used in stain and water-repellent products and firefighting foam — alters the gut microbiome of mice and could have implications for human health, according to an international team of researchers.

One avocado a day helps lower 'bad' cholesterol for heart healthy benefits

Move over, apples — new research from Penn State suggests that eating one avocado a day may help keep “bad cholesterol” at bay. According to the researchers, bad cholesterol can refer to both oxidized low-density lipoprotein (LDL) and small, dense LDL particles.

Penn State researchers receive grant to explore novel method of anticoagulation

Two Penn State biomedical engineering faculty members have received a two-year, $200,000 grant from the American Heart Association (AHA) to explore potential solutions to thrombosis, or blood clot formation, a prevalent issue with blood-contacting medical devices such as heart valves, blood pumps and cardiac stents.

Sleep deprivation may lead to slower metabolism, weight gain

Restricting sleep for just several days alters how we metabolize fats and changes how satisfied we are by a meal, according to new research conducted at Penn State and published in the Journal of Lipid Research.

Sense of smell, pollution and neurological disease connection explored

A consensus is building that air pollution can cause neurological diseases such as Alzheimer's disease and Parkinson's disease, but how fine, sooty particles cause problems in the brain is still an unanswered question. Now a team of Penn State researchers, using mice, have found a possible way, but more research is still needed.

Exercise may help teens sleep longer, more efficiently

Getting more exercise than normal — or being more sedentary than usual — for one day may be enough to affect sleep later that night, according to a new study led by Penn State.

White-throated sparrows are among the best-studied North American songbirds. With a typical wingspan of 6 to 7 inches, it breeds primarily in northern boreal coniferous and mixed forests and, a short-distance migrant, winters mainly in the southeastern U.S. To make these migrations, the bird's body changes significantly.

Songbird-body changes that allow migration may have human health implications

Songbirds that pack on as much as 50 percent of their body weight before migrating and that sleep very little, exhibit altered immune system and tissue-repair function during the journey, which may hold implications for human health, according to Penn State researchers.
