Expression-Dependent Tumor Pretargeting via Engineered Avidity.

Selective delivery of therapeutic modalities to tumor cells via binding of tumor-selective cell-surface biomarkers has empowered substantial advances in cancer treatment. Yet, tumor cells generally lack a truly specific biomarker that is present in high density on tumor tissue while being completely absent from healthy tissue. Rather, low but nonzero expression in healthy tissues results in on-target, off-tumor activity with detrimental side effects that constrain the therapeutic window or prevent use altogether.

Maternal oxygenation and fetal-neonatal mortality among patients with COVID-19 requiring advanced respiratory support in ICU: A multicenter prospective cohort study.

Objective: To explore the association of maternal characteristics, oxygenation, and mechanical ventilatory parameters with fetal and neonatal outcomes.

Methods: The present study was a multicenter, binational (Argentina/Colombia), prospective, cohort study, conducted in 21 intensive care units (ICUs) and including pregnant or postpartum patients with COVID-19 pneumonia requiring advanced respiratory support and their fetuses/neonates. Advanced respiratory support was defined as high-flow nasal cannula (HFNC), non-invasive ventilation (NIV) or invasive mechanical ventilation (IMV).

VIS-NIR hyperspectral imaging and multivariate analysis for direct characterization of pelagic fish species.

The identification of fish species and their physical and chemical characterization play a crucial role in the fishing industry, fish-food research and the management of marine resources. Traditional methods for species identification, such as expert observation, DNA barcoding and meta-barcoding, though effective, require labor-intensive laboratory work. Consequently, there is a pressing need for more objective and efficient methodologies for accurate fish species identification and characterization.
