Iron-Oxide Nanoparticles Embedded in 3D-Printed PLA/HA Scaffolds for Magnetic Hyperthermia Therapy: An Experimental-Numerical Analysis of Thermal Behavior.

Hyperthermia is nowadays intensively investigated as a promising strategy to improve the therapeutic efficacy against different types of cancer and resistant infections. In particular, the remote generation of localized hyperthermia by magnetic field through iron-oxide nanoparticles (IONPs) offers good thermal conductivity in a controlled area. The incorporation of these IONPs in 3D-printed scaffolds designed for bone tissue regeneration has been scarcely addressed in the literature.

Hydrothermal extraction of ulvans from Ulva spp. in a biorefinery approach.

A simple cascade process based on the hydrothermal fractionation of Ulva spp. biomass was proposed. Considering the overall extraction yields (50 %), ulvan recovery (23 %), and ulvan composition, structural, mechanical and cytotoxic properties, the selected optimal final heating temperature was 160 °C.

Shared germline genomic variants in two patients with double primary gastrointestinal stromal tumours (GISTs).

Background: Gastrointestinal stromal tumours (GISTs) are prevalent mesenchymal tumours of the gastrointestinal tract, commonly exhibiting structural variations in and genes. While the mutational profiling of somatic tumours is well described, the genes behind the susceptibility to develop GIST are not yet fully discovered. This study explores the genomic landscape of two primary GIST cases, aiming to identify shared germline pathogenic variants and shed light on potential key players in tumourigenesis.

Imaging the Granzyme Mediated Host Immune Response to Viral and Bacterial Pathogens Using Positron Emission Tomography.

Understanding how the host immune system engages complex pathogens is essential to developing therapeutic strategies to overcome their virulence. While granzymes are well understood to trigger apoptosis in infected host cells or bacteria, less is known about how the immune system mobilizes individual granzyme species to combat diverse pathogens. Toward the goal of studying individual granzyme function directly , we previously developed a new class of radiopharmaceuticals termed "restricted interaction peptides (RIPs)" that detect biochemically active endoproteases using positron emission tomography (PET).

HMGA1 regulates trabectedin sensitivity in advanced soft-tissue sarcoma (STS): A Spanish Group for Research on Sarcomas (GEIS) study.

HMGA1 is a structural epigenetic chromatin factor that has been associated with tumor progression and drug resistance. Here, we reported the prognostic/predictive value of HMGA1 for trabectedin in advanced soft-tissue sarcoma (STS) and the effect of inhibiting HMGA1 or the mTOR downstream pathway in trabectedin activity. The prognostic/predictive value of HMGA1 expression was assessed in a cohort of 301 STS patients at mRNA (n = 133) and protein level (n = 272), by HTG EdgeSeq transcriptomics and immunohistochemistry, respectively.
