Content validation of an electronic remote toxicity management system in adult patients undergoing cancer treatment: a prospective longitudinal study on the QuestOnco application.

Background: Cancer-treatment toxicity is common and symptoms must be identified quickly and accurately. Since symptom reporting during consultations is hampered by time constraints and patient/oncologist biases, patient-reported outcome-measure (PROM) questionnaires are useful. A strong shift to at-home cancer treatment has led to growing interest in remote symptom monitoring via electronic-PROMs (ePROMs).

A novel method to assess photobiomodulation in stimulating regenerative capacity and vascularization in zebrafish.

Photobiomodulation (PBM) therapy is a continuously growing approach to stimulating healing and reducing inflammation and pain. However, its effects in the fields of regenerative medicine and tissue engineering are still under investigation. Studying PBM effects on the regenerative capacity of zebrafish can allow the application of novel clinical approaches where the impact of PBM will be cross-linked with the stem-cell therapeutic approaches.

Nox4 is involved in acute kidney injury associated to intravascular hemolysis.

Massive intravascular hemolysis occurs not unfrequently in many clinical conditions. Breakdown of erythrocytes promotes the accumulation of heme-derivates in the kidney, increasing oxidative stress and cell death, thus promoting acute kidney injury (AKI). NADPH oxidase 4 (Nox4) is a major source of reactive oxygen species (ROS) in the kidney, however it is unknown the role of Nox4 in hemolysis and whether inhibition of this enzyme may protect from heme-mediated injury.

The mitochondrial Na/Ca exchanger NCLX is implied in the activation of hypoxia-inducible factors.

Eukaryotic cells and organisms depend on oxygen for basic living functions, and they display a panoply of adaptations to situations in which oxygen availability is diminished (hypoxia). A number of these responses in animals are mediated by changes in gene expression programs directed by hypoxia-inducible factors (HIFs), whose main mechanism of stabilization and functional activation in response to decreased cytosolic oxygen concentration was elucidated two decades ago. Human acute responses to hypoxia have been known for decades, although their precise molecular mechanism for oxygen sensing is not fully understood.

Non-apical mitoses contribute to cell delamination during mouse gastrulation.

During the epithelial-mesenchymal transition driving mouse embryo gastrulation, cells divide more frequently at the primitive streak, and half of those divisions happen away from the apical pole. These observations suggest that non-apical mitoses might play a role in cell delamination. We aim to uncover and challenge the molecular determinants of mitosis position in different regions of the epiblast through computational modeling and pharmacological treatments of embryos and stem cell-based epiblast spheroids.
