Accurate sequence-to-affinity models for SH2 domains from multi-round peptide binding assays coupled with free-energy regression.

Short linear peptide motifs play important roles in cell signaling. They can act as modification sites for enzymes and as recognition sites for peptide binding domains. SH2 domains bind specifically to tyrosine-phosphorylated proteins, with the affinity of the interaction depending strongly on the flanking sequence.

Changes in phosphorus due to pyrolysis and in the soil-plant system amended with sewage sludge biochar compared to conventional P fertilizers: A global meta-analysis.

Phosphorus (P) plays an essential role for plant growth, but conventional P sources used in agriculture are finite and non-renewable. As a result, there is a growing need to explore alternative P sources such as sewage sludge (SS) - a P-rich solid waste and valuable renewable resource that is often mismanaged globally. Pyrolysis is a promising technique for managing SS.

Nutrition biomarker assessment and exploration of the role of country foods to improve food security in the Sahtú Region, Canada.

Country foods (i.e. wild traditional food) are associated with improved nutrition for northern populations.

Frailty over the rainbow: a cross-sectional study of LGBT+ adults aged over 50 years.

Objective: To investigate differences in the prevalence of frailty between LGBT+ and non-LGBT+ older adults.

Methods: A cross-sectional study involving Brazilians aged 50 and over was performed. The participants were invited to participate in an anonymous online survey between August 2019 and January 2020.
