Temporal Microenvironment Mapping (μMap) of Intracellular Trafficking Pathways of Cell-Penetrating Peptides Across the Blood-Brain Barrier.

Peptides play critical roles in cellular functions such as signaling and immune regulation, and peptide-based biotherapeutics show great promise for treating various diseases. Among these, cell-penetrating peptides (CPPs) are particularly valuable for drug delivery due to their ability to cross cell membranes. However, the mechanisms underlying CPP-mediated transport, especially across the blood-brain barrier (BBB), remain poorly understood.

Closing the Gaps in Understanding PFAS Toxicology and Metabolism.

Per- and polyfluoroalkyl substances (PFAS) are nearly ubiquitous and found in rivers, soils, atmosphere, food packaging, clothing, cosmetics, commercial products, homes, drinking water, and humans and other organisms [...

Aminoalkylation of Alkenes Enabled by Triple Radical Sorting.

The direct synthesis of C(sp)-rich architectures is a driving force for innovation in synthetic organic chemistry. Such scaffolds impart beneficial properties onto drug molecules that correlate with greater clinical success. Consequently, there is a strong impetus to develop new methods by which to access sp-rich molecules from commercial feedstocks, such as alkenes.

Clinical and patient-reported outcomes in women offered oncoplastic breast-conserving surgery as an alternative to mastectomy: ANTHEM multicentre prospective cohort study.

Background: Oncoplastic breast-conserving surgery may be a better option than mastectomy, but high-quality comparative evidence is lacking. The aim of the ANTHEM study (ISRCTN18238549) was to explore clinical and patient-reported outcomes in a multicentre cohort of women offered oncoplastic breast-conserving surgery as an alternative to mastectomy with or without immediate breast reconstruction.

Methods: Women with invasive/pre-invasive breast cancer who were offered oncoplastic breast-conserving surgery with volume replacement or displacement techniques to avoid mastectomy were recruited prospectively.

Parallel Proteomic and Transcriptomic Microenvironment Mapping (μMap) of Nuclear Condensates in Living Cells.

Cellular activity is spatially organized across different organelles. While several structures are well-characterized, many organelles have unknown roles. Profiling biomolecular composition is key to understanding function but is difficult to achieve in the context of small, dynamic structures.
