Green Fluorescent Protein SELEX: Immobilization Chemistry and His‐Tag Epitope Bias

Angewandte Chemie, EarlyView.
Using green fluorescent proteins (GFP) as a target for SELEX, the untagged protein results in true protein‐binding aptamers, whereas using the His‐tagged protein results in aptamers biased toward the His‐tag epitope. The His‐tagged GFP provides a simple test for potential artifacts in previously selected aptamers for other His‐tagged proteins ...

Tophaceous Gout of the Patella: A Report of Two Cases

Case Reports in Rheumatology, 2012
Introduction. Tophaceous gout of the patella is rare and may masquerade as a tumour or tumour-like condition. Cases. We report two patients with gout involving the patella, one complicated by a pathological fracture and the other occurring in a bipartite

Hydrodynamic transport functions from quantum kinetic theory [PDF]

, 2000
Starting from the quantum kinetic field theory [E. Calzetta and B. L. Hu, Phys. Rev. D37, 2878 (1988)] constructed from the closed-time-path (CTP), two-particle-irreducible (2PI) effective action we show how to compute from first principles the shear and

A generalization of Szebehely's inverse problem of dynamics in dimension three [PDF]

, 2016
Extending a previous paper, we present a generalization in dimension 3 of the traditional Szebehely-type inverse problem. In that traditional setting, the data are curves determined as the intersection of two families of surfaces, and the problem is to ...

The Hoop Conjecture in Spherically Symmetric Spacetimes [PDF]

, 2009
We give general sufficient conditions for the existence of trapped surfaces due to concentration of matter in spherically symmetric initial data sets satisfying the dominant energy condition.

Peptide Vocabulary Analysis Reveals Ultra-Conservation and Homonymity in Protein Sequences

Bioinformatics and Biology Insights, 2007
A new algorithm is presented for vocabulary analysis (word detection) in texts of human origin. It performs at 60%–70% overall accuracy and greater than 80% accuracy for longer words, and approximately 85% sensitivity on Alice in Wonderland , a ...

The Frenet Serret Description of Gyroscopic Precession [PDF]

, 1993
The phenomenon of gyroscopic precession is studied within the framework of Frenet-Serret formalism adapted to quasi-Killing trajectories. Its relation to the congruence vorticity is highlighted with particular reference to the irrotational congruence ...

Simulations of the galaxy population constrained by observations from z=3 to the present day: implications for galactic winds and the fate of their ejecta [PDF]

, 2012
We apply Monte Carlo Markov Chain (MCMC) methods to large-scale simulations of galaxy formation in a LambdaCDM cosmology in order to explore how star formation and feedback are constrained by the observed luminosity and stellar mass functions of galaxies.

Loss of epithelial Gq and G11 signaling inhibits TGFβ production but promotes IL-33–mediated macrophage polarization and emphysema

Science Signaling, 2016
Signaling by Gq/11 is required for optimal TGFβ activation in the lung to prevent inflammation. Gq/11 signaling maintains healthy lungs Loss of signaling by the cytokine transforming growth factor–β (TGFβ) in mice results in emphysema-like symptoms ...
