Lanthanide binding peptide surfactants at air-aqueous interfaces for interfacial separation of rare earth elements.

Rare earth elements (REEs) are critical materials to modern technologies. They are obtained by selective separation from mining feedstocks consisting of mixtures of their trivalent cation. We are developing an all-aqueous, bioinspired, interfacial separation using peptides as amphiphilic molecular extractants.

Nuclear EGFR in breast cancer suppresses NK cell recruitment and cytotoxicity.

Natural Killer (NK) cells can target and destroy cancer cells, yet tumor microenvironments typically suppress NK cell recruitment and cytotoxicity. The epidermal growth factor receptor (EGFR) is a potent oncogene that can activate survival, migration, and proliferation pathways, and clinical data suggests it may also play an immunomodulating role in cancers. Recent work has demonstrated a novel role for nuclear EGFR (nEGFR) in regulating transcriptional events unique from the kinase domain.

Sphenopalatine ganglion (SPG) block for symptomatic relief of acute migraine.

A shortcut review of the literature was conducted to examine whether administering a sphenopalatine ganglion (SPG) block provides symptomatic relief in adult patients with acute migraine. 381 papers were found of which 4 included data on patients relevant to the specific clinical question, these are discussed in the paper. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of the best papers are tabulated.

Interfacial rheology of lanthanide binding peptide surfactants at the air-water interface.

Peptide surfactants (PEPS) are studied to capture and retain rare earth elements (REEs) at air-water interfaces to enable REE separations. Peptide sequences, designed to selectively bind REEs, depend crucially on the position of ligands within their binding loop domain. These ligands form a coordination sphere that wraps and retains the cation.
