Protocol for generating a co-culture of macrophages with breast cancer tumoroids.

Cancer progression and treatment outcomes are heavily influenced by the tumor microenvironment (TME), especially through immune cell interactions. Here, we present a protocol for generating co-cultures of tumoroids with macrophages, either semi-liquid or Matrigel-embedded. We describe steps for macrophage preparation, co-culture establishment, and medium adjustments to support cell viability and function.

NONO-related X-linked intellectual disability syndrome: further clinical and molecular delineation.

The X-linked NONO gene encodes Non-Pou Domain-Containing Octamer-Binding Protein, a multifunctional member of the DBHS family involved in transcriptional regulation, RNA splicing and DNA repair. Pathogenic variants in NONO cause Intellectual Developmental Disorder, X-linked Syndromic (MIM #300967), characterised by intellectual disability, neurodevelopmental delay, cardiomyopathy, such as left ventricular non-compaction (LVNC), and congenital heart defects such as including atrial septal defect (ASD), ventricular septal defect (VSD), patent ductus arteriosus (PDA), and patent foramen ovale (PFO). This study reports three new patients with pathogenic hemizygous frameshift variants in NONO identified with exome sequencing, broadening the clinical presentation.

Adverse effects of environmentally relevant microplastics on in vivo endpoints, oxidative stress, and mitogen-activated protein kinase signaling pathway and multixenobiotic resistance system in the marine rotifer Brachionus plicatilis.

This study compared the toxicological effects of environmentally relevant microplastics (MPs) on the marine rotifer Brachionus plicatilis, focusing on MPs derived from various sources, including fossil fuel-based low-density polyethylene, bio-based polylactic acid (PLA), biodegradable poly(butylene adipate-co-terephthalate), and a novel PLA modified with β-cyclodextrin. We assessed in vivo effects such as reproductive output and mortality, alongside in vitro oxidative stress responses, including oxidative stress, antioxidant enzyme activities, and activation of the mitogen-activated protein kinase (MAPK) signaling pathway and the multixenobiotic resistance (MXR) system. Reproductive output and lifespan reduced significantly across all MP types, ranging from 0.

Are ultrasound salivary parenchymal lesions more severe in primary Sjögren patients with a longer disease duration? A cross-sectional study.

Objectives: Salivary gland ultrasound (SGUS) has an interest in primary Sjögren's disease (pSD) for diagnosis, but the evolution of parenchymal lesions over time is unknown. The objective of this study was to assess the severity of ultrasound abnormalities in relation to pSD duration from the time of buccal dryness onset.

Methods: In this cross-sectional international multicentre study, patients with pSD according to the 2002 or 2016 ACR/EULAR classification criteria were included.

Accurate measurements of slice electron beam parameters at the undulator in seeded free-electron lasers.

The operation of modern free-electron lasers (FELs) necessitates precise knowledge of electron beam properties at the undulator to ensure the level of control required by increasingly demanding experiments. In seeded FELs, where only electrons interacting with the seed laser contribute to the process, it is crucial to determine the local values of these properties. We present a novel method, based on accurate modeling of the FEL process in high-gain harmonic generation, to accurately retrieve the electron beam slice energy spread, current and laser-induced energy modulation.

A novel microRNA promotes coxsackievirus B4 infection of pancreatic β cells.

The epidemiological association of coxsackievirus B infection with type 1 diabetes suggests that therapeutic strategies that reduce viral load could delay or prevent disease onset. Moreover, recent studies suggest that treatment with antiviral agents against coxsackievirus B may help preserve insulin levels in type 1 diabetic patients. In the current study, we performed small RNA-sequencing to show that infection of immortalized trophoblast cells with coxsackievirus caused differential regulation of several miRNAs.

Ceria-Catalysed Production of Dimethyl Carbonate from Methanol and CO: Effect of Using a Dehydrating Agent Combined with a Solid Cocatalyst.

The direct synthesis of dimethyl carbonate (DMC) from CO and methanol over ceria-based catalysts, in the presence of a dehydrating agent shifting the thermodynamical equilibrium of the reaction, has received significant interest recently. In this work, several dehydrating agents, such as molecular sieves, 2,2-dimethoxypropane (DMP), dimethoxymethane (DMM) and 1,1,1-trimethoxymethane (TMM), are combined with commercial ceria to compare their influence on the DMC yield obtained under the same set of operating conditions. TMM is found to be the most efficient; however, its conversion is not complete even after 48 h of reaction.

Law and Order of Colloidal Tectonics: From Molecules to Self-Assembled Colloids.

Since biochemists and biologists have progressed in understanding the mechanisms involved in living organisms, biological systems have become a source of inspiration for chemists. In this context, the concept of colloidal tectonics, describing the spontaneous formation of colloidal particles or supracolloidal structures in which the building blocks are called "tectons", has emerged. Therefore, a bottom-up edification of tectons towards (supra) colloidal structures is allowed.

Additive Manufacturing of Binary and Ternary Oxide Systems Using Two-Photon Polymerization and Low-Temperature Sintering.

Multicomponent oxide systems have many applications in different fields such as optics and medicine. In this work, we developed new hybrid photoresists based on a combination of an organic acrylate resin and an inorganic sol, suitable for 3D printing via two-photon polymerization (2PP). The inorganic sol contained precursors of a binary SiO-CaO or a ternary SiO-CaO-PO system.
