A 3D spheroid model for assessing nanocarrier-based drug delivery to solid tumors

Chitra Yadav, Alexander S. Evtushenko, Andrea Bistrović et al. · 2025 · npj Biomedical Innovations.

3D spheroid culture has emerged as a valuable tool for studying complex intratumoral processes and screening novel therapeutics in vitro. However, spheroids face reproducibility and data interpretation issues, which limit their utility. This work describes a simple and reproducible co-culture spheroid model compatible with high-throughput screening designed to study pancreatic ductal adenocarcinoma (PDAC), a highly therapy-resistant cancer. These spheroids, composed of both cancer and stromal cells, recapitulate key features of PDAC which are difficult to study in traditional 2D cell culture,

Biologics for bone regeneration: advances in cell, protein, gene, and mRNA therapies

Claudia Del Toro Runzer, Elizabeth R. Balmayor, Martijn van Griensven · 2026 · Bone Research

Bone fractures represent a significant global healthcare burden. Although fractures typically heal on their own, some fail to regenerate properly, leading to nonunion, a condition that causes prolonged disability, morbidity, and mortality. The challenge of treating nonunion fractures is further complicated in patients with underlying bone disorders where systemic and local factors impair bone healing. Traditional treatment approaches, including autografts, allografts, xenografts, and synthetic biomaterials, face limitations such as donor site pain, immune rejection, and insufficient mechanical

Null effect of perceived drum pattern complexity on the experience of groove

Olivier Senn, Florian Hoesl, Toni Bechtold et al. · 2024 · PLoS ONE

There is a broad consensus in groove research that the experience of groove, understood as a pleasurable urge to move in response to music, is to some extent related to the complexity of the rhythm. Specifically, music with medium rhythmic complexity has been found to motivate greater urge to move compared to low or high complexity music (inverted-U hypothesis). Studies that confirmed the inverted-U hypothesis usually based their measure of complexity on the rhythmic phenomenon of syncopation, where rhythms with more and/or stronger syncopation are considered to be more complex than less synco

Neuroinflammation in Schizophrenia: An Overview of Evidence and Implications for Pathophysiology

Evgeny A. Ermakov, Irina A. Mednova, Anastasiia S. Boiko et al. · 2025 · Journal of Integrative Neuroscience

Neuroinflammation, meaning an inflammatory process primarily occurring within the central nervous system (CNS), is thought to be associated with the pathogenesis of psychiatric disorders including schizophrenia (SC), although existing evidence is sometimes contradictory. This review critically summarizes the existing data on neuroinflammation and possible neuroinflammatory mechanisms in the pathogenesis of SC. Despite heterogeneity and inconsistency, the existing evidence indicates dysregulation of inflammatory genes and infiltration of the CNS parenchyma by immune cells, disturbances in the b

Non-Majorana origin of anomalous current-phase relation and Josephson diode effect in Bi 2 Se 3 /NbSe 2 Josephson junctions

Andrei Kudriashov, Xiong Zhou, Razmik A. Hovhannisyan et al. · 2025 · Science Advances

Josephson junctions (JJs) are key to superconducting quantum technologies and the search for self-conjugate quasiparticles potentially useful for fault-tolerant quantum computing. In topological insulator (TI)–based JJs, measuring the current-phase relation (CPR) can reveal unconventional effects such as Majorana bound states (MBS) and nonreciprocal transport. However, reconstructing CPR as a function of magnetic field has not been attempted. Here, we present a platform for field-dependent CPR measurements in planar JJs made of NbSe 2 and few-layer Bi 2 Se 3 . When a flux quantum Φ 0 thr

Proud to Not Own Stocks: How Identity Shapes Financial Decisions

Luca Henkel, Christian Zimpelmann · 2026 · Review of Financial Studies

Abstract This paper introduces a key factor influencing households’ decision to invest in the stock market: how people view stockholders. Using surveys we conducted with nearly 8,500 individuals from 11 countries, we document that a large majority hold negative views of stockholders based on identity-relevant characteristics. Linking survey and administrative data, we find that negative perceptions strongly predict households’ stock market participation. We show that negative perceptions causally influence household decision-making and provide evidence supporting identity concerns as the under

Towards a more realistic evaluation of machine learning models for bearing fault diagnosis

João Paulo Vieira, Victor Afonso Bauler, Rodrigo Kobashikawa Rosa et al. · 2026 · Mechanical Systems and Signal Processing

Reliable detection of bearing faults is essential for maintaining the safety and operational efficiency of rotating machinery. While recent advances in machine learning (ML), particularly deep learning, have shown strong performance in controlled settings, many studies fail to generalize to real-world applications due to methodological flaws, most notably data leakage. This paper investigates the issue of data leakage in vibration-based bearing fault diagnosis and its impact on model evaluation. We demonstrate that common dataset partitioning strategies, such as segment-wise and condition-wise

Anticancer efficacy of the hypoxia‐activated prodrug evofosfamide is enhanced in combination with proapoptotic receptor agonists against osteosarcoma

Vasilios Liapis, Aneta Zysk, Mark DeNichilo et al. · 2017 · Cancer Medicine

Tumor hypoxia is a major cause of treatment failure for a variety of malignancies. However, hypoxia also leads to treatment opportunities as demonstrated by the development of compounds that target regions of hypoxia within tumors. Evofosfamide is a hypoxia-activated prodrug that is created by linking the hypoxia-seeking 2-nitroimidazole moiety to the cytotoxic bromo-isophosphoramide mustard (Br-IPM). When evofosfamide is delivered to hypoxic regions of tumors, the DNA cross-linking toxin, Br-IPM, is released leading to cell death. This study assessed the anticancer efficacy of evofosfamide in

Relaxin Does Not Improve Angiotensin II-Induced Target-Organ Damage

Nadine Haase, Julianna Rugor, Łukasz Przybył et al. · 2014 · PLoS ONE

Relaxin is a corpus-luteum produced protein hormone with vasodilatatory, anti-fibrotic, and angiogenic properties that are opposite to angiotensin (Ang) II. We investigated whether or not relaxin ameliorates Ang II-induced target-organ damage. We used double transgenic rats harboring both human renin and angiotensinogen genes (dTGR) that develop severe hypertension, target-organ damage, and die untreated within 7-8 weeks. Recombinant relaxin at a low (26 μg/kg/d) and a high dose (240 μg/kg/d) was given to 4 week-old dTGR and age-matched Sprague-Dawley rats (SD). Systolic blood pressure increas
