Self Within Cultural Contexts

2025
Cultural frameworks for understanding the self are often categorized into two broad orientations: individualism and collectivism. These paradigms influence how people define themselves, relate to others, and interpret their social worlds. Each orientation offers distinct perspectives on autonomy, responsibility, and the role of the individual within a community.Individualistic CulturesIn individualistic cultures like North America and Western Europe, identity is understood as autonomous and...

We provide a step-by-step protocol for split-BioID, a protein fragments-complementation assay based on the proximity-labeling technique BioID. Activated on the interaction of two given proteins, it allows the proteomics analysis of context-dependent protein complexes in their native cellular environment. The method is simple, cost-effective and only requires standard laboratory equipment.

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions. These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Human co-infection is difficult to replicate in vitro. However, human malaria parasites can readily be cultured in vitro, as can freshly isolated human peripheral blood mononuclear cells naturally infected with HIV. This provides an excellent model for studying early immune responses to malaria parasites in the context of HIV co-infection.

Network Covalent Solids

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds. To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...
FAQs
They combine an interaction map with measurements that describe a defined tissue, cell type, disease state, or physiological condition. Gene expression, protein abundance, and clinical measurements can then be used to filter interactions, activate context-relevant connections, or reweight their importance. This produces a network whose structure reflects the selected biological setting rather than treating all interactions as equally relevant.
A general network may include many interactions that are not active or informative in a particular disease state. Context-specific analysis emphasizes connections supported by condition-dependent measurements, making disease-relevant regulatory pathways easier to distinguish. This can expose how system behavior changes in disease and help researchers focus on interactions that would otherwise remain obscured within a broader map.
The network can incorporate gene expression, protein abundance, and clinical measurements, with each data type contributing information about the selected biological context. These measurements help determine which interactions should be retained, activated, or assigned greater or lesser weight. Their integration connects molecular interaction patterns with tissue, cellular, disease-related, or physiological features relevant to the investigation.
Researchers first define the tissue, cell type, disease state, or physiological condition of interest. They then integrate an existing network with context-dependent measurements, such as molecular or clinical data. Interactions can be filtered, activated, or reweighted according to that evidence. The resulting map is interpreted to identify condition-relevant pathways and interactions for further medical analysis.
By linking interaction patterns to disease-related and clinical measurements, context-specific networks can highlight features associated with particular biological conditions. Those features may help identify candidate biomarkers or distinguish patient groups with different molecular or clinical characteristics. This network-based view adds pathway and interaction context to measurements that might otherwise be interpreted as isolated signals.
The approach can identify regulatory pathways and interactions that are especially relevant in a defined disease context. Researchers can use those context-linked features to prioritize potential drug targets and to examine how therapeutic strategies relate to the underlying system. In medicine, this supports more precise treatment planning and contributes to the development of personalized therapeutic strategies.
