Expedient discovery of fluorogenic amino acid-based probes one-pot palladium-catalysed arylation of tyrosine.

To overcome the limitations of using large extrinsic chromophores for biological imaging, fluorescent unnatural α-amino acids have been widely adopted as intrinsic peptidic probes. Although various classes have been successfully utilised for imaging applications, novel amino acid probes readily prepared through operationally simple synthetic methodology are still required. Here, we report a new approach for the synthesis of unnatural α-amino acids a one-pot process involving activation and palladium-catalysed arylation of tyrosine.

The Tolerance of Anti-cancer Systemic Therapy in the Elderly study sought to evaluate the CARG score prospectively in a chemotherapy-naïve UK population.

Methods And Analysis: This multicentre, prospective, observational study recruited patients aged ≥65 years commencing first-line chemotherapy for any solid organ malignancy or setting.

Laser localization with soft‑channel minimally invasive surgery in cerebral hemorrhage.

The aim of the present study was to evaluate the efficacy and safety of laser localization combined with soft-channel minimally invasive surgery (MIS) for the treatment of cerebral hemorrhage, and to develop stereotactic alternatives that are cost-effective, safe and precise for underdeveloped regions. To meet this aim, 60 patients with cerebral hemorrhage were randomly assigned to the control group (n=30) or the study group (n=30). The patients in the study group were treated with laser localization combined with soft-channel MIS to remove the hematoma, whereas the control group was treated with YL-1 needle puncture to drain the intracranial hemorrhage.

Women and birth partners' experiences of cervical ripening at home and in hospital.

Background: In the United Kingdom, induction of labour rates are rapidly rising, and around a third of pregnant women undergo the procedure. The first stage, cervical ripening, traditionally carried out in hospital, is increasingly offered outpatient - or 'at home'. The current induction of labour rates place considerable demand on maternity services and impact women's experiences of care, and at home cervical ripening has been suggested as potential solution for alleviating these.

PathoGD: an integrative genomics approach to primer and guide RNA design for CRISPR-based diagnostics.

Critical to the success of CRISPR-based diagnostic assays is the selection of a diagnostic target highly specific to the organism of interest, a process often requiring iterative cycles of manual selection, optimisation, and redesign. Here we present PathoGD, a bioinformatic pipeline for rapid and high-throughput design of RPA primers and gRNAs for CRISPR-Cas12a-based pathogen detection. PathoGD is fully automated, leverages publicly available sequences and is scalable to large datasets, allowing rapid continuous monitoring and validation of primer/gRNA sets to ensure ongoing assay relevance.

Loss of ARID1A accelerates prostate tumourigenesis with a proliferative collagen-poor phenotype through co-operation with AP1 subunit cFos.

Background: Prostate cancer (PC) is the commonest male visceral cancer, and second leading cause of cancer mortality in men in the Western world.

Methods: Using a forward-mutagenesis Sleeping Beauty (SB) transposon-based screen in a Probasin Cre-Recombinase (Pb-Cre) Pten-deficient mouse model of PC, we identified Arid1a loss as a driver in the development of metastatic disease.

Results: The insertion of transposon in the Arid1a gene resulted in a 60% reduction of Arid1a expression, and reduced tumour free survival (SB:Pten Arid1a median 226 days vs SB:Pten Arid1a 293 days, p = 0.

Pasteurisation temperatures effectively inactivate influenza A viruses in milk.

In late 2023 an H5N1 lineage of high pathogenicity avian influenza virus (HPAIV) began circulating in American dairy cattle Concerningly, high titres of virus were detected in cows' milk, raising the concern that milk could be a route of human infection. Cows' milk is typically pasteurised to render it safe for human consumption, but the effectiveness of pasteurisation on influenza viruses in milk was uncertain. To assess this, here we evaluate heat inactivation in milk for a panel of different influenza viruses.

Automated insulin delivery during the first 6 months postpartum (AiDAPT): a prespecified extension study.

Background: Clinical guidelines in the UK and elsewhere do not specifically address hybrid closed loop (HCL) use in the postpartum period when the demands of caring for a newborn are paramount. Our aim was to evaluate the safety and efficacy of HCL use during the first 6 months postpartum compared with standard care.

Methods: In this prespecified extension to a multicentre, randomised controlled trial, pregnant women with type 1 diabetes at nine UK sites were followed up for 6 months postpartum.

Competitive behaviors in Serratia marcescens are coordinately regulated by a lifestyle switch frequently inactivated in the clinical environment.

Opportunistic bacterial pathogens must compete with other bacteria and switch between host- and environment-adapted states. Type VI secretion systems (T6SSs) occur widely in gram-negative bacteria and can efficiently kill neighboring competitors. We determined the distribution of T6SSs across the genus Serratia and observed that a highly conserved antibacterial T6SS is differentially active between closely related clinical isolates of Serratia marcescens.

A miniature FUS transducer based on an acoustic Fresnel lens for integration with a surgical robot.

A new focussed ultrasound surgery (FUS) transducer for soft tissue ablation is proposed, with a miniaturised configuration that can be readily integrated with a surgical robot. The transducer fills a gap in FUS technology at this size, with capability for acoustic focus steering within a very simple transducer configuration. Miniaturisation is enabled by the incorporation of an acoustic Fresnel lens as the focussing element driven by a single piezoceramic disc.

Biomimetic Silk Nanoparticle Manufacture: Calcium Ion-Mediated Assembly.

Silk has emerged as an interesting candidate among protein-based nanocarriers due to its favorable properties, including biocompatibility and a broad spectrum of processing options to tune particle critical quality attributes. The silk protein conformation during storage in the middle silk gland of the silkworm is modulated by various factors, including the most abundant metallic ion, calcium ion (Ca). Here, we report spiking of liquid silk with calcium ions to modulate the silk nanoparticle size.

Multidimensional Classification and Prediction of Outcome Following Traumatic Brain Injury.

Setting: Rehabilitation hospital.

Participants: A total of 467 individuals with TBI, aged 17 to 87 (M = 44.

Potential Infectious Complications in Pig Xenograft Donors and Recipients.

Preclinical and clinical xenotransplantation trials have shown that successful outcomes depend on a number of factors including the prevention of xenozoonoses. Preclinical trials involving pig kidneys and hearts transplanted into various non-human primates have revealed the potential impact of pig pathogens being present in the transplanted organ/tissue, mainly viruses. The concept of "designated pathogen-free donor animals" was developed to ensure elimination of pathogens during the breeding of donor animals to mitigate this occurrence.

Effects of Diverting Stoma Creation in Minimally Invasive Surgery for Rectal Cancer.

Objectives: In rectal cancer surgery, a diverting stoma (DS) is used to prevent severe anastomotic leakage (AL), peritonitis, reoperation, and longer hospitalization. DS creation has increased in the last few decades, without establishment of clear criteria for construction of a DS. Therefore, the goal of the study was to investigate the validity of DS construction based on risk factors for AL, as an approach to reduce the number of stoma creations.

Objectives: Traditional scoring systems have been widely used to predict acute pancreatitis (AP) severity but have limitations in predictive accuracy. This study investigates the use of machine learning (ML) algorithms to improve predictive accuracy in AP.

Methods: A retrospective study was conducted using data from 101 AP patients in a tertiary hospital in Türkiye.

The effect of verdict system on juror decisions: a quantitative meta-analysis.

We study the effect of the Scottish three-verdict system (guilty, not guilty, not proven) and the Anglo-American two-verdict system (guilty, not guilty) on juror decisions by combining data sets from 10 mock trials reported in suitable studies. A logistic regression with random effects uses the exact number of convictions and acquittals in 10 mock trials from a total of 1778 jurors to reliably estimate the effect of verdict system. We found a statistically significant verdict effect suggesting that the odds for a conviction by a juror are about 0.

Management of Unruptured Infectious Intracranial Aneurysms in Infective Endocarditis: A Case Report and Literature Review.

Infectious intracranial aneurysms (IIAs) are rare lesions with fragile arterial walls located within the aneurysms, carrying a high risk of rupture. Standard management often involves antibiotic therapy and parent artery occlusion; however, the latter carries a significant risk of cerebral infarction. This report presents a case of an unruptured IIA following cerebral infarction, successfully treated with coil embolization while preserving the parent artery.
