PALB2 self-interaction controls homologous recombination. [PDF]

, 2012
PALB2 is essential for BRCA2 anchorage to nuclear structures and for homologous recombinational repair of DNA double-strand breaks. Here, we report that the N-terminal coiled-coil motif of PALB2 regulates its self-association and homologous recombination.

How Aspects of Self-Compassion Contribute to Wellbeing and the Effect of Age [PDF]

, 2012
For modern high strength steels, instead of metal instability, ductile damage triggered by the formation of microvoids or microcracks resulting from the complex material microstructure, has become the key factor responsible for the final failure in the ...

Rheological properties and damage-control mechanism of oil-based drilling fluid with different types of weighting agents [PDF]

Royal Society Open Science, 2018
The great amount of solid particles contained in a weighting agent is a major cause of the problems in both rheology properties and damage control mechanism of an oil-based drilling fluid (OBM).
