T follicular helper cell expansion and hyperimmunoglobulinemia with spontaneous IgE production to dietary antigens in IgA-deficient mice.

Immunoglobulin A (IgA), the most abundantly produced antibody at mucosal surfaces, is thought to play key roles in immune responses to respiratory and enteric pathogens and in the regulation of commensal colonization. Low IgA levels have been associated with recurrent infections and immune dysregulation, including inflammatory bowel disease and autoimmunity. Levels of IgA in maternal breast milk and infant stool are both inversely associated with the emergence of immune responses to food antigens in infants and, in naturally resolving food sensitivity and immunotherapy protocols, the induction of IgA antibodies to dietary antigens has been associated with the acquisition of food tolerance.

Floating-embedded stems reduce tibial stress shielding in total knee revision arthroplasty.

Background: Total knee arthroplasty (TKA) is one of the most common orthopaedic procedures and the number of patients which undergo TKA will continue to rise in the coming years. Consecutively, the number of necessary revision surgeries will increase. One of the main reasons for revision surgery is aseptic loosening because of a so-called stress-shielding effect.

IRE1 is a Promising Therapeutic Target in Pancreatic Cancer.

Pancreatic cancer (PC) is one of the most aggressive malignancies, characterized by an increasing incidence and unfavorable prognosis. Despite recent advances, surgical resection combined with chemotherapy remains the only potentially curative therapeutic option. Therefore, it is of paramount importance to identify novel therapeutic targets and develop effective treatment strategies.

Identification of dissipation pathways for pharmaceuticals in soils - a modelling approach.

Concentrations of pollutants like pharmaceuticals in soils typically decrease over time, though it often remains unclear whether this dissipation is caused by the transformation of the pollutant or a decreasing extractability. We developed a mathematical model that (1) explores the plausibility of different dissipation pathways, and (2) allows the quantification of concentration differences between aqueous soil extracts and soil solution. The model considers soil particles as uniform spheres, kinetic sorption towards an equilibrium (Freundlich model), and two dissipation pathways, irreversible transformation and mineralization (following 1 order kinetics) as well as the formation of non-extractable residues intraparticle diffusion.

Efficacy of treatment options for complicated urinary tract infections including acute pyelonephritis: a systematic literature review and network meta-analysis.

Compared with uncomplicated urinary tract infections (UTIs), complicated UTIs (cUTIs) including acute pyelonephritis (AP) present with significant morbidity, a higher risk of treatment failure and typically require longer courses of treatment, or alternative antibiotics. The emergence of drug-resistant organisms represents a considerable challenge in the treatment of patients with cUTIs/AP and has limited antibiotic options. Carbapenems are considered the current last line of therapy, however, carbapenem resistance represents a growing problem.

Echocardiography of the right heart in pulmonary arterial hypertension: insights from the ULTRA RIGHT VALUE study.

Methodological challenges using routine clinical care data for real-world evidence: a rapid review utilizing a systematic literature search and focus group discussion.

Background: The integration of real-world evidence (RWE) from real-world data (RWD) in clinical research is crucial for bridging the gap between clinical trial results and real-world outcomes. Analyzing routinely collected data to generate clinical evidence faces methodological concerns like confounding and bias, similar to prospectively documented observational studies. This study focuses on additional limitations frequently reported in the literature, providing an overview of the challenges and biases inherent to analyzing routine clinical care data, including health claims data (hereafter: routine data).

Structural changes of muscle spindles in the multifidus muscle after intervertebral disk injury are resolved by targeted muscle activation.

Purpose: Fibrosis of muscle spindles (sensory organs) in back muscles induced by intervertebral disc (IVD) degeneration could limit transmission of muscle stretch to the sensory receptor and explain the proprioceptive deficits common in back pain. Exercise reduces back muscles fibrosis. This study investigated whether targeted muscle activation via neurostimulation reverses or resolves muscle spindle fibrosis in a model of IVD injury.

However, exposure and vulnerability to pollutants are understudied in tropical species, and the relationships between various pollutants and the trophic ecology of seabirds are poorly understood.

Bis-3-chloropiperidines: a novel motif for anthelmintic drug design.

Parasites account for huge economic losses by infecting agriculturally important plants and animals. Furthermore, morbidity and death caused by parasites affect a large part of the world population, especially in economically weak regions. Anthelmintic drugs to tackle this challenge remain scarce and their efficiency becomes increasingly endangered by the advent of drug resistance development.

Functional resting state connectivity is differentially associated with IL-6 and TNF-α in depression and in healthy controls.

Inflammatory processes have been implicated in the pathophysiology of depression. In human studies, inflammation has been shown to act as a critical disease modifier, promoting susceptibility to depression and modulating specific endophenotypes of depression. However, there is scant documentation of how inflammatory processes are associated with neural activity in patients with depression.

C5 complement inhibition versus FcRn modulation in generalised myasthenia gravis.

Background: Myasthenia gravis (MG) is an autoimmune disorder affecting neuromuscular junctions, leading to fluctuating muscle weakness. While many patients respond well to standard immunosuppression, a substantial subgroup faces ongoing disease activity. Emerging treatments such as complement factor C5 inhibition (C5IT) and neonatal Fc receptor (FcRn) antagonism hold promise for these patients.
