New needle-free 'exosome' treatment to reduce wrinkles in UV-exposed mice

In the quest for a more youthful appearance, many people slather ointments on their skin or undergo injections of dermal fillers. But topical treatments often aren't very effective because they don't penetrate deep within the skin, whereas the results from injections typically last for only a few months and can be painful.

Johns Hopkins researchers link a gene to melanoma growth and spread

Using a small noncoding RNA, microRNA 211, and tools that track the stability and decay of the protein-coding and noncoding RNAs in lab-grown melanoma cells, a team led by a Johns Hopkins Kimmel Cancer Center researcher identified highly unstable RNA molecules in human melanomas, including a novel miR-211 target gene DUSP3.

Study on gene mutations may lead to better diagnosis and treatment for cancer

When a cell divides into two daughter cells, it must replicate its DNA according to a very specific scenario. In the presence of some disruptive elements, however, cancer cells are unable to perform this operation optimally; replication then takes place more slowly and less efficiently.

Epileptic seizures not likely to be predicted by changes in brain wave patterns

Until now, certain brain wave patterns were regarded as indicators; however, a study by the University of Bonn did not find any evidence for this Epileptic seizures can probably not be predicted by changes in brain wave patterns that were previously assumed to be characteristic precursors.

Acne may be a natural, transient inflammatory state when facial skin is exposed to microbes

Adolescent acne does not always result in a pathological condition; rather, it may be a natural, transient inflammatory state occurring when the maturing facial skin is exposed to new microbes and enhanced production of an oily substance called sebum, according to a Forum article published on September 26 in the journal Trends in Immunology.

Mummies show atherosclerosis was prevalent in ancient times

A new study published in the American Heart Journal used spectroscopic imaging techniques to ‘see’ fatty plaques in the arteries of ancient mummies. This shows that the people of ancient times also had a high incidence of clogged arteries, showing that heart disease is of very old lineage.
