Background: Congenital nasolacrimal duct obstructions that persist after 9 months of age often require surgical intervention through probing and stenting of the tear duct. These procedures typically occur under general anesthesia in an operating room setting. We propose a novel approach using intravenous sedation outside the operating room.

Sugar sweetened beverages (SSB) are a concern for Indigenous populations and are associated with multiple chronic diseases. To address this concern, we culturally tailored and tested the feasibility of an evidence-based SSB-reducing curriculum. The modified curriculum was designed for Indigenous men and is thematically based on traditional values, ancestral teachings, and community strengths while promoting healthy lifestyles.

Therapy resistance and metastasis, the most fatal steps in cancer, are often triggered by a (partial) activation of the epithelial-mesenchymal transition (EMT) programme. A mesenchymal phenotype predisposes to ferroptosis, a cell death pathway exerted by an iron and oxygen-radical-mediated peroxidation of phospholipids containing polyunsaturated fatty acids. We here show that various forms of EMT activation, including TGFβ stimulation and acquired therapy resistance, increase ferroptosis susceptibility in cancer cells, which depends on the EMT transcription factor Zeb1.

The electromagnetic form factors of the proton and neutron encode information on the spatial structure of their charge and magnetization distributions. While measurements of the proton are relatively straightforward, the lack of a free neutron target makes measurements of the neutron's electromagnetic structure more challenging and more sensitive to experimental or model-dependent uncertainties. Various experiments have attempted to extract the neutron form factors from scattering from the neutron in deuterium, with different techniques providing different, and sometimes large, systematic uncertainties.
