Infants born at the limits of viability present neonatologists in particular and society in general with difficult challenges. Ethical and legal considerations establish a framework for action, although this varies between countries, departments and individuals and shows dynamic changes over time. This brief review includes a vignette telling a familiar story. In this case, the parents ask searching questions and the caring, knowledgeable neonatologist uses up-to-date information to offer empathic and thoughtful guidance - a challenge for all.

With the rapid advancement of plant phenotyping research, understanding plant genetic information and growth trends has become crucial. Measuring seedling length is a key criterion for assessing seed viability, but traditional ruler-based methods are time-consuming and labor-intensive. To address these limitations, we propose an efficient deep learning approach to enhance plant seedling phenotyping analysis.

To further the development of an in vitro model that faithfully recapitulates drug disposition of orally administered drugs, we investigated the utility of human enteroid monolayers to simultaneously assess intestinal drug absorption and first-pass metabolism processes. We cultured human enteroid monolayers from 3 donors, derived via biopsies containing duodenal stem cells that were propagated and then differentiated atop permeable Transwell inserts, and confirmed transformation into a largely enterocyte population via RNA sequencing analysis and immunocytochemistry (ICC) assays. Proper cell morphology was assessed and confirmed via bright field microscopy and ICC imaging of tight junction proteins and other apically and basolaterally localized proteins.

Zinc (Zn)-based alloys and composites are anticipated to emerge as a category of degradable metallic biomaterials with exceptional prospects for bone-implant applications owing to their superior biocompatibility and biofunctionality. Unfortunately, the limited strength of Zn alloys in their as-cast state restricts their use in clinical applications. In this study, we started with pure magnesium (Mg) powders and Zn sheets, and successfully fabricated MgZn/Zn composites using accumulative roll bonding (ARB).

Superparamagnetic iron oxide nanoparticles (SPIONs) are known to be good MRI contrasts, but they have a high tendency to aggregate and their biocompatibility is limited. Hyaluronic acid is highly biocompatible, can provide SPION with colloidal stability, and interacts specifically with tumor cells through the CD44 receptor; therefore, it was used as a stabilizing layer. We successfully obtained SPION coated with hyaluronic acid and further functionalized it with folic acid to construct a dual-targeted system.
