Validation of the PANAMA-Score for Survival and Benefit of Adjuvant Therapy in Patients with Resected Pancreatic Cancer After Neoadjuvant FOLFIRINOX.

Aim: To validate the prognostic value of the PAncreatic NeoAdjuvant MAssachusetts (PANAMA)-score and to determine its predictive ability for survival benefit derived from adjuvant treatment in patients after resection of pancreatic ductal adenocarcinoma (PDAC) following neoadjuvant FOLFIRINOX.

Background: The PANAMA-score was developed to guide prognostication in patients after neoadjuvant therapy and resection for PDAC. As this score focuses on the risk for residual disease after resection, it might also be able to select patients who benefit from adjuvant after neoadjuvant therapy.

Single-Virus Microscopy of Biochemical Events in Viral Entry.

Cell entry by enveloped viruses involves a set of multistep, multivalent interactions between viral and host proteins as well as manipulation of nanoscale membrane mechanics by these interacting partners. A mechanistic understanding of these events has been challenging due to the complex nature of the interactions and the event-to-event heterogeneity involved. Single-virus microscopy has emerged as a powerful technique to probe viral binding and fusion kinetics.

Native Mass Spectrometry Captures the Conformational Plasticity of Proteins with Low-Complexity Domains.

Disordered regions are an important functional feature of many multidomain proteins. A prime example is proteins in membraneless organelles, which contain folded domains that engage in specific interactions and disordered low-complexity (LC) domains that mediate liquid-liquid phase separation. Studying these complex architectures remains challenging due to their conformational variability.

Decoding the Molecular Basis of the Specificity of an Anti-sTn Antibody.

The mucin -glycan sialyl Tn antigen (sTn, Neu5Acα2-6GalNAcα1--Ser/Thr) is an antigen associated with different types of cancers, often linked with a higher risk of metastasis and poor prognosis. Despite efforts to develop anti-sTn antibodies with high specificity for diagnostics and immunotherapy, challenges in eliciting high-affinity antibodies for glycan structures have limited their effectiveness, leading to low titers and short protection durations. Experimental structural insights into anti-sTn antibody specificity are lacking, hindering their optimization for cancer cell recognition.

Applying the Sabatier Principle to Decipher the Surface-Structure-Dependent Catalysis of Different Starch Granules by Pullulanase.

Interfacial enzyme catalysis is widespread in both nature and industry. Granular starch is a sustainable and abundant raw material for which a rigorous correlation of the surface structure with enzymatic degradation is lacking. Here pullulanase-catalyzed debranching of 12 granular starches varying in amylopectin contents and branch chain contents and lengths is shown to present a biphasic relationship characteristic of the Sabatier principle.

Exploiting spatial isomerism to modulate the assembled phase and rheological response of compositionally identical sugar-based surfactants.

For decades, extensive surfactant libraries have been developed to meet the requirements of downstream applications. However, achieving functional diversity has traditionally demanded a vast array of chemical motifs and synthetic pathways. Herein, a new approach for surfactant design based on structural isomerism is utilised to access a wide spectrum of functionalities.

Sex and APOE genotype modulate neuropsychological profile and depression in temporal lobe epilepsy.

Introduction: Temporal lobe epilepsy is the most common form of focal epilepsy, often associated with cognitive impairments, particularly in memory functions, and depression. Sex and APOE ε4 genotype play a crucial role in modulating cognitive outcomes and depression in various neurological conditions like Alzheimer's disease. However, the combined effects of APOE genotype and sex on cognitive performance and depression in temporal lobe epilepsy have not been previously investigated.

Inflammation biomarkers and Alzheimer's disease: A pilot study using NULISAseq.

Introduction: Increasing evidence links amyloid beta (Aβ) aggregation with inflammation. This pilot study investigated the use of an immunoassay panel to map biomarker changes in patients with Alzheimer's disease (AD). Furthermore, we evaluated the stability of protein quantification after multiple freeze-thaw cycles (FTCs).

Associations between socioeconomic factors and PSA testing in a population-based organised testing programme and routine healthcare: a register-based study of 50-year-old men.

Objective: Population-based, organised prostate cancer testing (OPT) programmes were started in Sweden in 2020. The influence of socioeconomic factors on prostate cancer testing in this setting is not known. We examined associations between socioeconomic factors and (1) participation in OPT and (2) unorganised prostate-specific antigen (PSA) testing.

Association of pre-existing cardiovascular disease with administration of fluoropyrimidine chemotherapy in patients with gastrointestinal malignancies.

Objective: Fluoropyrimidine chemotherapy is a first-line treatment for many gastrointestinal (GI) cancers, however, cardiotoxicity concerns may limit administration in patients with pre-existing cardiovascular disease (CVD). This study investigated the association of pre-existing CVD with use of fluoropyrimidine chemotherapy in tumour-eligible GI cancer patients.

Methods And Analysis: National cancer registry data from the Virtual Cardio-Oncology Research Initiative from England between 2014 and 2018 was used to identify GI cancer patients eligible to receive fluoropyrimidine chemotherapy.

Blood-based DNA methylation markers for lung cancer prediction.

Objective: Screening high-risk individuals with low-dose CT reduces mortality from lung cancer, but many lung cancers occur in individuals who are not eligible for screening. Risk biomarkers may be useful to refine risk models and improve screening eligibility criteria. We evaluated if blood-based DNA methylation markers can improve a traditional lung cancer prediction model.

Immune dynamics throughout life in relation to sex hormones and perspectives gained from gender-affirming hormone therapy.

Biological sex is closely associated with the properties and extent of the immune response, with males and females showing different susceptibilities to diseases and variations in immunity. Androgens, predominantly in males, generally suppress immune responses, while estrogens, more abundant in females, tend to enhance immunity. It is also established that sex hormones at least partially explain sex biases in different diseases, particularly autoimmune diseases in females.

Two-stage diffuse fluorescence tomography for monitoring of drug distribution in photodynamic therapy of tumors.

Significance: The spatial distribution of the photosensitizing drug concentration is an important parameter for predicting the photodynamic therapy (PDT) outcome. Current diffuse fluorescence tomography methods lack accuracy in quantifying drug concentration. The development of accurate methods for monitoring the temporal evolution of the drug distribution in tissue can advance the real-time light dosimetry in PDT of tumors, leading to better treatment outcomes.

Ionic silver coating of orthopedic implants may impair osteogenic differentiation and mineralization.

Silver (Ag) possesses potent antimicrobial properties and is used as a coating for medical devices. The impact of silver ions released from orthopedic implants on the differentiation and osteoid formation of different osteogenic cells has yet to be systematically studied. In the present study, human mesenchymal stem cells (hMSCs) and primary human osteoblasts (hOBs) were exposed to different static Ag concentrations (0, 0.

A scoping review was carried out from the relevant literature available from PubMed, Scopus and Web of Science.

Classification performance and reproducibility of GPT-4 omni for information extraction from veterinary electronic health records.

Large language models (LLMs) can extract information from veterinary electronic health records (EHRs), but performance differences between models, the effect of hyperparameter settings, and the influence of text ambiguity have not been previously evaluated. This study addresses these gaps by comparing the performance of GPT-4 omni (GPT-4o) and GPT-3.5 Turbo under different conditions and by investigating the relationship between human interobserver agreement and LLM errors.

Behavioral characterization of the mdx5cv, mdx52 and DMD-null mouse models of Duchenne muscular dystrophy.

Duchenne muscular dystrophy is a severe neuromuscular disorder, caused by mutations in the DMD gene. Normally, the DMD gene gives rise to multiple dystrophin isoforms, of which multiple are expressed in the brain. The location of the mutation determines the number of dystrophin isoforms affected, and the absence thereof leads to behavioral and cognitive impairments.

Changes in the provision and utilisation of health care services for chronic health conditions during the COVID-19 pandemic in rural northeast South Africa: an interrupted time series analysis.

Background: The COVID-19 pandemic has impacted the provision and utilisation of health care services with varying magnitude across settings due to spatial temporal variation in the burden of COVID-19 cases and the roll-out of local COVID-19 response policies. This study assesses changes in the provision and utilisation of health care services for three major chronic health conditions (HIV/AIDS, hypertension, and diabetes) over the pre-COVID-19 and COVID-19 pandemic periods in a rural South African sub-district of Agincourt.

Methods: Segmented interrupted time series regression models are applied to assess changes in the number of medication collection visits and new diagnoses for HIV/AIDS, hypertension, and diabetes from 1 January 2018 to 30 September 2021 covering the pre- COVID-19 period and the first three waves of the COVID-19 pandemic.

Health behavioural change - the influence of social-ecological factors and health identity.

Health behaviour is crucial for influencing health, making it a key component in health promotion. However, changing behaviours is complex, as many factors interact to determine health behaviours. Information, awareness, and knowledge are important but not enough.

Sulfur Lone Pairs Open Avenues for π* → n Orange-to-Red TADF and OLEDs.

It is always important and fascinating to explore new organic emitters that exploit unconventional pathways to unveil their emission with unique properties, such as thermally activated delayed fluorescence (TADF). In this study, we report that the rarely explored sulfur lone pair (n) is a promising alternative, where the correlated π* → n emission can be used to attain strong TADF and thus practical OLEDs. The designed strategy incorporates several key concepts (Figure 1a), in which the persulfide aromatic spirocycle enhances spin-orbit coupling, thereby increasing the intersystem crossing rate.
