A chemical dimerization approach is developed to induce phase separation of APB nuclear bodies involved in telomere elongation in alternative lengthening of telomeres (ALT) cancer cells. It reveals that ALT telomere-associated promyelocytic leukemia nuclear body (APB) fusion leads to telomere clustering to provide templates for homology-directed telomere synthesis, an ability that is decoupled from APB function in enriching DNA repair factors.

Porous polymeric membranes have emerged as the core technology in the field of separation. But some challenges remain for several methods used for membrane fabrication, suggesting the need for a critical review of the literature. We present here an overview on porous polymeric membrane preparation and characterization for two commonly used polymers: polysulfone and poly (vinylidene fluoride). Five different methods for membrane fabrication are introduced: non-solvent induced phase separation, vapor-induced phase separation, electrospinning, track etching and sintering. The key factors of each method are discussed, including the solvent and non-solvent system type and composition, the polymer solution composition and concentration, the processing parameters, and the ambient conditions. To evaluate these methods, a brief description on membrane characterization is given related to morphology and performance. One objective of this review is to present the basics for selecting an appropriate method and membrane fabrication systems with appropriate processing conditions to produce membranes with the desired morphology, performance and stability, as well as to select the best methods to determine these properties.
