An N-Substituted Polyurea Coating with High Affinity for Heparin
ASAIO Journal, 1993 A new N-substituted polyurea with tertiary amino groups in the polycarbamidic chain (NPUTA) has been synthesized. The polymer is soluble in C1-C4 alcohols, has high adhesion to polar molds, and has high H2O uptake (130-150%). The material can be coated on many biomaterials (polyurethanes, charcoal hemosorbents, cellulosic hemodialysis membranes), and ...

Evolutionary models for insertions and deletions in a probabilistic modeling framework
BMC Bioinformatics, 2005 Background Probabilistic models for sequence comparison (such as hidden Markov models and pair hidden Markov models for proteins and mRNAs, or their context-free grammar counterparts for structural RNAs) often assume a fixed degree of divergence. Ideally

Substituted Purines as High-Affinity Histamine H3 Receptor Ligands
Pharmaceuticals, 2022 Continuing with our program to obtain new histamine H3 receptor (H3R) ligands, in this work we present the synthesis, H3R affinity and in silico studies of a series of eight new synthetically accessible purine derivatives. These compounds are designed from the isosteric replacement of the scaffold presented in our previous ligand, pyrrolo[2,3-d ...

Rotation-k Affine-Power-Affine-like Multiple Substitution-Boxes for Secure Communication
CoRR, 2016 Substitution boxes with thorough cryptographic strengths are essential for the development of strong encryption systems. They are the only portions capable of inducing nonlinearity in symmetric encryption systems. Bijective substitution boxes having both high nonlinearities and high algebraic complexities are the most desirable to thwart linear ...

FEBS Letters, EarlyView.CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Self-adaptive encryption algorithm for image based on affine and composed chaos
Tongxin xuebao, 2012 On the basis of three-dimensional affine transformation in limited integer domain and composed chaos,a novel digital image encryption algorithm was proposed.Firstly,it scrambled pixels’ position and confused pixels’ value according to corresponding ...

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Investigating transcription factor dynamics in health and disease using FRAP
FEBS Letters, EarlyView.FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

About linear and affine equivalence of substitutions
Prikladnaya diskretnaya matematika, 2013 Summary: The results of computer experiments with a software implementation of algorithms for determining the linear and affine equivalence of substitutions are presented. The detailed description of the algorithms is given. Experimental operation time of the algorithms is compared with the theoretical complexity of the problem.
