Integrating In Silico and In Vitro Tools for Optimized Antibody Development-Design of Therapeutic Anti-oxMIF Antibodies.

Background: Rigorous assessment of antibody developability is crucial for optimizing lead candidates before progressing to clinical studies. Recent advances in predictive tools for protein structures, surface properties, stability, and immunogenicity have streamlined the development of new biologics. However, accurate prediction of the impact of single amino acid substitutions on antibody structures remains challenging, due to the diversity of complementarity-determining regions (CDRs), particularly CDR3s.

Quantification of alcohol intake in patients with steatotic liver disease and excessive alcohol intake.

Background & Aims: Quantifying alcohol intake is crucial for subclassifying participants with steatotic liver disease (SLD) and interpreting clinical trials of alcohol-related liver disease (ALD) and metabolic and alcohol-related liver disease (MetALD). However, the accuracy of self-reported alcohol intake is considered imprecise. We compared the diagnostic and prognostic utility of self-reported alcohol intake with blood-based biomarkers of alcohol intake: phosphatidylethanol (PEth) and carbohydrate-deficient transferrin (CDT).

Development, validation, and prognostic evaluation of LiverPRO for the prediction of significant liver fibrosis in primary care: a prospective cohort study.

Background: Clinically significant liver fibrosis is associated with future adverse events in patients with steatotic liver disease. We designed a software tool for detection of clinically significant liver fibrosis in primary care.

Methods: In this prospective cohort study, we developed and validated LiverPRO using six independent cohorts from Denmark, Germany, and England that included patients from primary and secondary care with steatotic liver disease related to alcohol or metabolic dysfunction.

Metabolic dysfunction and alcohol-related liver disease (MetALD): Position statement by an expert panel on alcohol-related liver disease.

In this position statement, we explore the intricate relationship between alcohol intake and metabolic dysfunction in the context of the 2023 nomenclature update for steatotic liver disease (SLD). Recent and lifetime alcohol use should be accurately assessed in all patients with SLD to facilitate classification of alcohol use in grams of alcohol per week. Alcohol biomarkers (i.

Fecal microbial load is a major determinant of gut microbiome variation and a confounder for disease associations.

The microbiota in individual habitats differ in both relative composition and absolute abundance. While sequencing approaches determine the relative abundances of taxa and genes, they do not provide information on their absolute abundances. Here, we developed a machine-learning approach to predict fecal microbial loads (microbial cells per gram) solely from relative abundance data.

Hepatocellular Cancer Surveillance in Patients with Advanced Chronic Liver Disease.

Background: Patients with advanced chronic liver disease (ACLD) are at high risk of developing hepatocellular carcinoma (HCC). Therefore, biannual surveillance is recommended. This large-scale multicenter study aimed to stratify the risk of HCC development in ACLD.

Targeting of oxidized Macrophage Migration Inhibitory Factor (oxMIF) with antibody ON104 attenuates the severity of glomerulonephritis.

The oxidized form of Macrophage Migration Inhibitory Factor (oxMIF) has been identified as the disease-related isoform of MIF, exerting pathological functions in inflamed tissue. In this study, we aimed to explore the in vivo effects of the neutralizing anti-oxMIF antibody ON104 in a rat model of crescentic glomerulonephritis (CGN), to better understand its disease modifying activities. WKY rats received a single intravenous injection of a rabbit nephrotoxic serum (NTS), targeting rat glomerular basement membrane to induce CGN.

Lipid profiling identifies modifiable signatures of cardiometabolic risk in children and adolescents with obesity.

Pediatric obesity is a progressive, chronic disease that can lead to serious cardiometabolic complications. Here we investigated the peripheral lipidome in 958 children and adolescents with overweight or obesity and 373 with normal weight, in a cross-sectional study. We also implemented a family-based, personalized program to assess the effects of obesity management on 186 children and adolescents in a clinical setting.

Survey of Sun Exposure Levels, Sun Protection Behavior, and Skin Cancer Risk Awareness in Junior Tennis Players.

Despite a growing number of young adults developing skin cancers, little is known about the sun-protective behavior of high school athletes exposed to high levels of UV radiation, such as junior tennis players. To investigate the frequency and quality of their sun protective behaviors, a web-based, anonymous survey was conducted among tennis players at high school varsity matches and United States Tennis Association tournaments in Southern California. Although 92.

Population screening for cirrhosis.

In response to the growing health crisis of liver-related morbidity and mortality, screening for liver cirrhosis has emerged as a promising strategy for early detection and timely intervention. By identifying individuals with severe fibrosis or compensated cirrhosis, screening holds the promise of enhancing treatment outcomes, delaying disease progression, and ultimately improving the quality of life of affected individuals. Clinical practice guidelines from international scientific societies currently recommend targeted screening strategies, investigating high-risk populations with known risk factors of liver disease.

Working memory enhancement using real-time phase-tuned transcranial alternating current stimulation.

Background: Prior work has shown that transcranial alternating current stimulation (tACS) of parietooccipital alpha oscillations (8-14 Hz) can modulate working memory (WM) performance as a function of the phase lag to endogenous oscillations. However, leveraging this effect using real-time phase-tuned tACS has not been feasible so far due to stimulation artifacts preventing continuous phase tracking.

Objectives And Hypothesis: We aimed to develop a system that tracks and adapts the phase lag between tACS and ongoing parietooccipital alpha oscillations in real-time.

Intra-Cochlear Electrode Position Impacts the Preservation of Residual Hearing in an Animal Model of Cochlear Implant Surgery.

Introduction: Preservation of residual hearing after cochlear implantation remains challenging. There are several approaches to preserve residual hearing, but the configuration of the implant electrode array seems to play a major role. Lateral wall electrode arrays are seemingly more favorable in this context.

Redox-dependent plasticity of oxMIF facilitates its interaction with CD74 and therapeutic antibodies.

MIF is a ubiquitous protein involved in proinflammatory processes, which undergoes an oxidation-driven conformational change to oxidized (ox)MIF. We demonstrate that hypochlorous acid, produced by neutrophil-released myeloperoxidase (MPO) under inflammatory conditions, effectively oxidizes MIF into the oxMIF isoform, which is specifically recognized by the anti-oxMIF therapeutic antibody, ON104. NMR investigation of MIF oxidized by the MPO system revealed increased flexibility throughout the MIF structure, including at several catalytic and allosteric sites.

Pretargeted Radioimmunotherapy with the Novel Anti-oxMIF/HSG Bispecific Antibody ON105 Results in Significant Tumor Regression in Murine Models of Cancer.

Radioimmunotherapy (RIT) uses monoclonal antibodies to deliver radionuclides to cancer cells or the tumor microenvironment and has shown promise in treating localized and diffuse tumors. Although RIT agents have gained FDA/EMA approval for certain hematologic malignancies, effectiveness of RIT in treating solid tumors remains limited. In this study, we present PreTarg-it®, a novel approach for pretargeted RIT, providing optimized delivery of payloads in a two-step regimen.

The interplay between birth weight and obesity in determining childhood and adolescent cardiometabolic risk.

Background: Birth weight (BW) is associated with risk of cardiometabolic disease (CMD) in adulthood, which may depend on the state of obesity, in particular if developed at a young age. We hypothesised that BW and a polygenic score (PGS) for BW were associated with cardiometabolic risk and related plasma protein levels in children and adolescents. We aimed to determine the modifying effect of childhood obesity on these associations.

This review investigates that, in 2023, fatty liver disease underwent a name change to "steatotic liver disease" (SLD). SLD now includes metabolic dysfunction-associated steatotic liver disease (MASLD), alcohol-related liver disease (ALD), and metabolic and alcohol-related liver disease (MetALD). The renaming aims to better incorporate alcohol intake and metabolic risk factors into disease classification and to diminish the stigma associated with the previous nomenclature.
