Phonon antibunching, a phenomenon arising from the quantum statistics of mechanical vibrations, has attracted significant attention due to its potential applications in quantum information processing, sensing, and energy harvesting. Here, we present a comprehensive investigation of phonon antibunching in a system consisting of three weakly nonlinear coupled nanomechanical resonators. We analytically derive and study the antibunching behavior of phonons in the proposed system and bring insight into the underlying mechanisms.

Background And Aim: The clinical severity of acute pancreatitis is unpredictable, ranging from self-limiting disease to life-threatening inflammation. The determinants of severe acute pancreatitis (SAP) are unclear. We aim to identify clinical variables and single nucleotide polymorphisms (SNP) associated with SAP.

However, investigations using culture and molecular barcodes have provided only a low-resolution view of this important microbial community. We therefore explored the potential of culturomics and metagenomic binning to generate a catalogue of reference genomes from the healthy human oesophageal microbiome, alongside a comparison set from saliva.

Creating a culture of safety and prevention of AEs should be part of routine endoscopy practice. Appropriate patient selection for procedures, informed consent, periprocedure risk assessments and a team approach, all contribute to reducing AEs.

This occurred 2 years post-curative treatment (minimally invasive oesophagectomy with neo-adjuvant chemotherapy) for an oesophageal adenocarcinoma staged T3N0M0. On examination, patient had left-sided hemiparesis.

This multi-centre study aims to assess postoperative morbidity between HO and CMIO according to the full Esophagectomy Complications Consensus Group (ECCG) complication platform.
Methods: All consecutive patients undergoing an Ivor-Lewis HO or Ivor-Lewis CMIO for cancer between 2016 and 2018 in three UK tertiary centres were included.
A large amount of ammonia volatilization from the agricultural system causes environmental problems and increases production costs. Conservation agriculture has emerged as an alternate and sustainable crop production system. Therefore, in the present study, ammonia losses from different agricultural practices were evaluated for the wheat crop under different tillage practices.
View Article and Find Full Text PDFThe human oesophagus is home to a complex microbial community, the oesophageal microbiome. Despite decades of work, we still have only a poor, low-resolution view of this community, which makes it hard to distinguish hope from hype when it comes to assessing links between the oesophageal microbiome and cancer. Here we review the potential importance of this microbiome and discuss new approaches, including culturomics, metagenomics, and recovery of whole-genome sequences, that bring renewed hope for an in-depth characterisation of this community that could deliver translational impact.

CT scans showed that this was partially adherent to the spleen, with erosion of the gastric wall and suggested impending perforation. Given the risk of perforation, further surgical intervention (gastrectomy and splenectomy) was considered; however, after multidisciplinary team discussion, we chose to offer chemotherapy and careful inpatient observation instead.

Patients And Methods: Prospectively collected perioperative data of patients that underwent cytoreduction for advanced EOC, between 2014 and 2018, were analysed. Patients were divided in two groups on the basis of whether cholecystectomy was performed.
Pancreatic cancer is the 11th most common cancer in the UK and has the worst prognosis of any tumour with minimal improvements in survival over recent decades. As most patients are either ineligible for surgery or may decline chemotherapy, the emphasis is on control of symptoms and management of complications such as poor nutritional status. The time period between informing the patient of their diagnosis and commencing cancer treatments presents a valuable opportunity to proactively identify and treat symptoms to optimise patients' overall well-being.
View Article and Find Full Text PDFBackground: The human genome is an under-researched area of pre-operative risk stratification. Studies of genetic polymorphisms and their associations with acute post-operative complications in gastrointestinal surgery have reported statistically significant results, but have varied in methodology, genetic variations studied, and conclusions reached. To provide clarity, we conducted a systematic review and meta-analysis of single nucleotide polymorphisms and their association with post-operative complications after major gastrointestinal surgery.
