Preliminary findings of a 'test bundle' to accelerate the diagnosis of MS and NMOSD following optic neuritis.

No study has investigated the length of time it takes to diagnose multiple sclerosis (MS) or neuromyelitis optic spectrum disorder (NMOSD, aquaporin 4 antibody disease or myelin oligodendrocyte glycoprotein antibody disease, MOGAD) following the onset of de novo optic neuritis (ON). Minimizing the time between ON and downstream diagnoses needs urgency since early diagnosis equals early treatment. The time elapsed from ON to a subsequent diagnosis of MS/NMOSD was estimated through analysis of retrospective data collected from the Axon Registry (AR) of the American Academy of Neurology (AAN) and from the University of Kentucky (UK), Lexington.

Laparoscopically assisted versus open oesophagectomy for patients with oesophageal cancer-the Randomised Oesophagectomy: Minimally Invasive or Open (ROMIO) study: protocol for a randomised controlled trial (RCT).

Introduction: Surgery (oesophagectomy), with neoadjuvant chemo(radio)therapy, is the main curative treatment for patients with oesophageal cancer. Several surgical approaches can be used to remove an oesophageal tumour. The Ivor Lewis (two-phase procedure) is usually used in the UK.

Single-molecule analysis of i-motif within self-assembled DNA duplexes and nanocircles.

The cytosine (C)-rich sequences that can fold into tetraplex structures known as i-motif are prevalent in genomic DNA. Recent studies of i-motif-forming sequences have shown increasing evidence of their roles in gene regulation. However, most of these studies have been performed in short single-stranded oligonucleotides, far from the intracellular environment.
