Optimizing approaches for targeted integration of transgenic cassettes by integrase mediated cassette exchange in mouse and human stem cells.

To enable robust expression of transgenes in stem cells, recombinase mediated cassette exchange at safe harbour loci is frequently adopted. The choice of recombinase enzyme is a critical parameter to ensure maximum efficiency and accuracy of the integration event. We have explored the serine recombinase family of site-specific integrases and have directly compared the efficiency of PhiC31, W-beta and Bxb1 integrase for targeted transgene integration at the Gt(ROSA)26Sor locus in mouse embryonic stem cells.

Why CEOs need advanced education and training for optimizing decisions in the development of innovative medicinal products? justification and recommendation.

Chief executives have been educated and trained how to handle business, to take executive decisions, and take care of financial and human resources in favor of the company they are leading. CEOs (chief executive officers) of innovative pharmaceutical businesses, among others, have only seldomly been trained to understand the immense time periods involved between decisions and their moment of impact, and the skills and languages used by their internal and external R&D (research and development) staff. R&D staff and regulators, however, have undergone full training, and are usually capable of understanding each other across their various specialties (among them compound finding, quality, safety, efficacy, efficiency, risk assessment and management).

Disentangling Sources of Momentum Fluctuations in Xe+Xe and Pb+Pb Collisions with the ATLAS Detector.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Electrochemical Control of the Ultrafast Lattice Response of a Layered Semimetal.

The unique layer-stacking in two-dimensional (2D) van der Waals materials facilitates the formation of nearly degenerate phases of matter and opens novel routes for the design of low-power, reconfigurable functional materials. Electrochemical ion intercalation between stacked layers offers a promising approach to stabilize bulk metastable phases and to explore the effects of extreme carrier doping and strain. However, in situ characterization methods to study the structural evolution and dynamical functional properties of these intercalated materials remains limited.

Gold-Catalyzed Access to Pyrrolo- and (Aryl)Indolo-Fused Phenazines.

Novel fused phenazines were synthesized through a combination of gold-catalyzed hydroamination and cascade cyclization reactions towards azaacenes. In total, 30 new compounds were synthesized and investigated with respect to their structural and optoelectronic properties. In solution, these targets exhibit strong green to red emission, with quantum yields of up to 60 %.
