Multi-omic biomarker panel in pancreatic cyst fluid and serum predicts patients at a high risk of pancreatic cancer development.

Integration of multi-omic data for the purposes of biomarker discovery can provide novel and robust panels across multiple biological compartments. Appropriate analytical methods are key to ensuring accurate and meaningful outputs in the multi-omic setting. Here, we extensively profile the proteome and transcriptome of patient pancreatic cyst fluid (PCF) (n = 32) and serum (n = 68), before integrating matched omic and biofluid data, to identify biomarkers of pancreatic cancer risk.

Annual migrations, vertical habitat use and fidelity of Atlantic bluefin tuna tracked from waters off the United Kingdom.

Understanding the spatial ecology of commercially exploited species is vital for their conservation. Atlantic bluefin tuna (Thunnus thynnus, ABT) are increasingly observed in northeast Atlantic waters, yet knowledge of these individuals' spatial ecology remains limited. We investigate the horizontal and vertical habitat use of ABT (158 to 241 cm curved fork length; CFL) tracked from waters off the United Kingdom (UK) using pop-up satellite archival tags (n = 63).

Molecular and spatial analysis of tertiary lymphoid structures in Sjogren's syndrome.

Tertiary lymphoid structures play important roles in autoimmune and non-autoimmune conditions. While many of the molecular mechanisms involved in tertiary lymphoid structure formation have been identified, the cellular sources and temporal and spatial relationship remain unknown. Here we use combine single-cell RNA-sequencing, spatial transcriptomics and proteomics of minor salivary glands of patients with Sjogren's disease and Sicca Syndrome, with ex-vivo functional studies to construct a cellular and spatial map of key components involved in the formation and function of tertiary lymphoid structures.

Do pollinators play a role in shaping the essential amino acids found in nectar?

Plants produce floral nectar as a reward for pollinators, which contains carbohydrates and amino acids (AAs). We designed experiments to test whether pollinators could exert selection pressure on the profiles of AAs in nectar. We used HPLC to measure the free AAs and sugars in the nectar of 102 UK plant species.

miRNA-target complementarity in cnidarians resembles its counterpart in plants.

microRNAs (miRNAs) are important post-transcriptional regulators that activate silencing mechanisms by annealing to mRNA transcripts. While plant miRNAs match their targets with nearly-full complementarity leading to mRNA cleavage, miRNAs in most animals require only a short sequence called 'seed' to inhibit target translation. Recent findings showed that miRNAs in cnidarians, early-branching metazoans, act similarly to plant miRNAs, by exhibiting full complementarity and target cleavage; however, it remained unknown if seed-based regulation was possible in cnidarians.

Coupling metabolomics and exome sequencing reveals graded effects of rare damaging heterozygous variants on gene function and human traits.

Genetic studies of the metabolome can uncover enzymatic and transport processes shaping human metabolism. Using rare variant aggregation testing based on whole-exome sequencing data to detect genes associated with levels of 1,294 plasma and 1,396 urine metabolites, we discovered 235 gene-metabolite associations, many previously unreported. Complementary approaches (genetic, computational (in silico gene knockouts in whole-body models of human metabolism) and one experimental proof of principle) provided orthogonal evidence that studies of rare, damaging variants in the heterozygous state permit inferences concordant with those from inborn errors of metabolism.

Ironing out differences in attenuation and blooming artifact in acute stroke thrombi.

This study aims to improve our understanding of acute ischemic stroke clot imaging by integrating CT attenuation information with MRI susceptibility signal of thrombi. For this proof-of-principle experimental study, fifty-seven clot analogs were produced using ovine venous blood with a broad histological spectrum. Each clot analog was analyzed to determine its RBC content and chemical composition, including water, Fe III, sodium, pH, and pO2.

Risk-factor modification to prevent recurrent atrial fibrillation after catheter ablation.

More and more patients with atrial fibrillation are undergoing catheter ablation as a rhythm-control strategy, but the recurrence rate after the procedure is high. A wide array of risk factors contribute to the pathogenesis of atrial fibrillation, including hypertension, diabetes mellitus, dyslipidemia, obesity, obstructive sleep apnea, metabolic dysfunction-associated steatotic liver disease (MASLD), smoking, alcohol consumption, and physical inactivity. This review summarizes the emerging evidence for periablation risk-factor modification to optimize postablation outcomes.

Combination of Apigenin and Melatonin with nanostructured lipid carriers as anti-inflammatory ocular treatment.

Ocular inflammation is a complex pathology with limited treatment options. While traditional therapies have side effects, novel approaches, such as natural compounds like Apigenin (APG) and Melatonin (MEL) offer promising solutions. APG and MEL, in combination with nanostructured lipid carriers (NLC), may provide a synergistic effect in treating ocular inflammation, potentially improving patient outcomes and reducing adverse effects.

IPEM topical report: guidance on 3D printing in radiotherapy.

There has been an increase in the availability and utilization of commercially available 3D printers in radiotherapy, with applications in phantoms, brachytherapy applicators, bolus, compensators, and immobilization devices. Additive manufacturing in the form of 3D printing has the advantage of rapid production of personalized patient specific prints or customized phantoms within a short timeframe. One of the barriers to uptake has been the lack of guidance.

Transplant and Nontransplant Salvage Therapy in Pediatric Relapsed or Refractory Hodgkin Lymphoma: The EuroNet-PHL-R1 Phase 3 Nonrandomized Clinical Trial.

Importance: The current standard-of-care salvage therapy in relapsed/refractory classic Hodgkin lymphoma (cHL) includes consolidation high-dose chemotherapy (HDCT)/autologous stem cell transplant (aSCT).

Objective: To investigate whether presalvage risk factors and fludeoxyglucose-18 (FDG) positron emission tomography (PET) response to reinduction chemotherapy can guide escalation or de-escalation between HDCT/aSCT or transplant-free consolidation with radiotherapy to minimize toxic effects while maintaining high cure rates.

Design, Setting, And Participants: EuroNet-PHL-R1 was a nonrandomized clinical trial that enrolled patients younger than 18 years with first relapsed/refractory cHL across 68 sites in 13 countries in Europe between January 2007 and January 2013.

RET signalling in the pituitary: a double-edged sword for differentiation, apoptosis and therapeutic strategies in acromegaly.

The discovery of RET mutations in Multiple Endocrine Neoplasia 2A (MEN2A) in 1993 ignited a revolution in our understanding of this versatile receptor. Since then, RET's influence has expanded to encompass diverse organs, including the pituitary gland. This review explores the multifaceted role of RET in somatotrophs, focusing on two opposing pathways: proliferation versus differentiation and apoptosis.

Preclinical Development of Magnetic Nanoparticles for Hyperthermia Treatment of Pancreatic Cancer.

Pancreatic ductal adenocarcinoma (PDAC) is a very challenging disease with a very poor prognosis. It is characterized by a dense desmoplastic stroma that hampers drug penetration and limits the effectiveness of conventional chemotherapy (CT). As an alternative, the combination of CT with hyperthermia (HT) has been proposed as an innovative treatment modality for PDAC.

An Ultramicroporous Physisorbent Sustained by a Trifecta of Directional Supramolecular Interactions.

2D and 3D porous coordination networks (PCNs) as exemplified by metal-organic frameworks, MOFs, have garnered interest for their potential utility as sorbents for molecular separations and storage. The inherent modularity of PCNs has enabled the development of crystal engineering strategies for systematic fine-tuning of pore size and chemistry in families of related PCNs. The same cannot be said about one-dimensional (1D) coordination polymers, CPs, which are understudied with respect to porosity.

Where Are the Irish in Research on Ethnic Health Inequalities in Britain? A State-Of-The-Art Literature Review.

Decisions about ethnic groups studied in health research shape recommendations. If a group is not included in research, its ability to call for policy change is limited. Despite health inequalities for the Irish in Britain in the 20th century, recent research on health is likely to combine the White Irish with White British, whereas Irish people of colour are not mentioned at all.
