Mass Spectrometry News and Research

RSS

Mass spectrometry is an analytical method used to identify different compounds based on the atomic sample constitution of the molecules and their charge state, which enables “blind” analysis of an unknown sample without any prior knowledge of its composition.

Nicotine delivery different for different e-cigarettes finds study

A new study from Penn State College of Medicine researchers has shown that different electronic cigarettes or “electronic nicotine delivery system (ENDS)” have different rates of nicotine delivery to the users. Most popular brand of e-cigarettes JUUL for example has been found to deliver more nicotine at a faster rate compared to other brands.

Popular pod-based electronic cigarette can deliver more nicotine at faster rate than others

When it comes to nicotine delivery, not all electronic cigarettes are created equally, according to Penn State researchers. New research from Penn State College of Medicine shows that JUUL, a popular pod-based electronic cigarette, can deliver more nicotine at a faster rate than most other types of electronic cigarettes that have been studied.

Study uncovers how cells 'forget their past' while developing into a specific cell

All cells in the body contain the same genetic material. The difference between cells therefore depends solely on which genes are expressed or ‘turned on’.

Researchers identify new kidney cancer subtypes and clues to better diagnosis, treatment

In what is believed to be the most comprehensive molecular characterization to date of the most common - and often treatment-resistant - form of kidney cancer, researchers at Johns Hopkins' departments of pathology and oncology, Johns Hopkins Kimmel Cancer Center, and the Johns Hopkins University School of Medicine report evidence for at least three distinct subtypes of clear cell renal cell carcinoma (ccRCC), along with new revelations about the proteins that define them.

Some types of proteins can stabilize damaged DNA

At the University of Copenhagen, researchers have discovered how some types of proteins stabilize damaged DNA and thereby preserve DNA function and integrity. This new finding also explains why people with inborn or acquired defects in certain proteins cannot keep their DNA stable and develop diseases such as cancer.

White and brown fat cells send very different signals to rest of the body

Many people might not realize that they have different types of body fat. Most of it is white fat that sits on your stomach, hips and thighs, for example. White fat is an energy storage that our body can use when food is scarce.
