In this paper we describe the interfacial synthesis of conjugated microporous polymers (CMP) on sacrificial substrates, and the dissolution of the substrate for the preparation of freestanding CMP nanomembranes. In addition, we will describe how the fragile nanomembranes can be transferred to other substrates.

Drosophila Egg Collection and Dechorionation: A Method to Remove the Outermost Egg Layer
0 Views •
2023
The Drosophila embryo is surrounded by protective outer membranes. To gain access to the embryo, the chorion–the outermost of the membranes–is often removed. This video describes a commonly used method of dechorionation using sodium hypochlorite. The example protocol demonstrates the procedure while employing sterile techniques necessary for axenic or gnotobiotic animal rearing.

We illustrate the application of 1H(15N,αγ)12C resonant nuclear reaction analysis (NRA) to quantitatively evaluate the density of hydrogen atoms on the surface, in the volume, and at an interfacial layer of solid materials. The near-surface hydrogen depth profiling of a Pd(110) single crystal and of SiO2/Si(100) stacks is described.

Protein-protein Interfaces

Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a polypeptide...
FAQs
Molecular exchange allows neighboring tumor and stromal environments to influence one another, while receptor-ligand signaling converts locally available signals into cellular responses. Examining both mechanisms helps researchers connect boundary conditions with changes in tumor organization, communication, or behavior. This combined view is useful when determining how interactions at a local interface contribute to invasion or altered responses to treatment.
Cell-cell adhesion helps determine how tumor cells remain organized or interact with surrounding populations, whereas chemical and physical gradients create uneven conditions across the boundary. These variables can produce regional differences in signaling, transport, and cellular behavior. Studying them together clarifies why cancer-related processes may vary within the same model rather than occurring uniformly throughout the tissue or environment.
They examine interactions between tumor cells and surrounding stroma rather than interpreting tumor behavior in isolation. Measurements or observations can focus on molecular exchange, adhesion, receptor-ligand signaling, and transport across the boundary. This comparison helps identify effects associated with the surrounding environment and supports a more complete analysis of how local microenvironmental conditions shape tumor organization and behavior.
Transport across changing chemical or physical gradients can show how conditions vary through an interface and how those variations influence communication between adjacent populations. Such analyses help researchers relate spatially changing environments to tumor organization, invasion, metastatic spread, or treatment response. The resulting information adds a local, boundary-focused perspective that may be missed when gradients are not considered.
A study can begin by selecting a cancer model that represents the relevant tumor and surrounding environment, then examining the boundary through molecular exchange, cell-cell adhesion, receptor-ligand signaling, or transport. Researchers can connect these observations with changes in tumor organization, invasion, metastatic behavior, or treatment response. Consistent experimental approaches are important for making comparisons reproducible across models.
These approaches are useful when the research question concerns communication between tumor cells and surrounding stroma, local control of invasion, or the behavior of cells at changing environmental boundaries. They also support studies of metastatic spread and treatment response. By preserving attention to the microenvironment, interface-focused experiments can provide information relevant to developing more predictive cancer models and therapeutic strategies.
