The effects of smoking on fractures and ligament injuries

...his may lead to a delay in restoring biomechanical stability of the healing MCL. The authors conclude: "Ultimately, a better understanding of the cellular and molecular mechanisms involved in the MCL healing process will allow physicians to improve or speed the healing process, as well as potentially overcome ...

Satellites shed light on global warming

... warming and the importance of ice shelves for the stability of glaciers up-stream." "The disintegration processes observed at Larsen Ice Shelf are very relevant for estimating the future response to climatic warming of the much larger ice masses of West Antarctica, which contain freshwater equivalent to s...

DNA analysis reveals rapid population shift among Pleistocene cave bears

...logy, published by Cell Press. To investigate the stability of ancient cave bear populations over time, the researchers obtained DNA samples from 29 cave bear teeth from three geographically close caves in the Ach Valley, near the Danube River in modern-day southern Germany. Twenty of the teeth ultimately pro...

Researchers from the UGR use a bacterium to obtain biopreservatives from food

...ty and in the hydrophobic nature and thermodynamic stability of the molecule. We made this study by changing the amino acids into others with different properties." The results of this work made it possible to conclude that while some of the mutated amino acids are essential for biological activity, others ...

Stability of mRNA/DNA and DNA/DNA duplexes modulates mRNA transcription

...n Academy of Sciences, suggests that thermodynamic stability of DNA/DNA and RNA/DNA duplexes influences mRNA tr...authors present a calculation of the thermodynamic stability of DNA/DNA and mRNA/DNA duplexes across the genomes of four species in the genus Saccharomyces. The ...

Keeping the body in sync -- The stability of cellular clocks

Latent memory of cells comes to life

...isms in individual cells. The mechanism gives both stability and openness to new influences which the cell could need to change state. Nature has a partner which controls the cells latent memory....

How to lose weight and not go hungry: HU researcher develops drug that mimics feeling of 'fullness'

... which they call BL-3020, displayed good metabolic stability to intestinal enzymes when swallowed, and that it was able to cross the intestinal wall and gain access into the blood stream. Once in the blood, it could make its way to the MC4R receptor and “close the circuit” to send out the “full” signal. Th...
