Decision rules in the diagnostic work-up of aortic dissection.

A short cut review of the literature was carried out to examine whether a decision rule in conjunction with a D-dimer can be used to rule out aortic dissection. 117 unique papers were found of which three systematic reviews included data on patients relevant to the 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.

Excited state dynamics of azanaphthalenes reveal opportunities for the rational design of photoactive molecules.

Various photoactive molecules contain motifs built on aza-aromatic heterocycles, although a detailed understanding of the excited state photophysics and photochemistry in such systems is not fully developed. To help address this issue, the non-adiabatic dynamics operating in azanaphthalenes under hexane solvation was studied following 267 nm excitation using ultrafast transient absorption spectroscopy. Specifically, the species quinoline, isoquinoline, quinazoline, quinoxaline, 1,6-naphthyridine, and 1,8-naphthyridine were investigated, providing a systematic variation in the relative positioning of nitrogen heteroatom centres within a bicyclic aromatic structure.

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.
