An Assay to Measure the Accumulation of a Fluorescent Antibiotic Probe in Bacterial Cells

2025
This video demonstrates an assay to measure the accumulation of a fluorescent antibiotic probe in bacterial cells. Exposure to an efflux pump inhibitor disrupts the transmembrane proton gradient in bacterial cells, upon which a fluorophore-conjugated antibiotic is added. Inhibition of efflux pumps due to the disrupted proton gradient causes accumulation of the antibiotic inside the bacteria. Bacterial cells are lysed, and the fluorescence intensity is measured to confirm antibiotic accumulation.

Cost Accumulation and Flow

In manufacturing, production costs are accumulated and tracked to understand how resources are consumed and how they contribute to the final product. This process, known as cost accumulation, involves recording material, labor, and overhead costs and linking them to specific cost objects, such as individual products or production processes.Costs flow through inventory accounts in a sequence that mirrors the physical movement of goods. Initially, raw materials are recorded in the raw materials...

The heterogeneous intra-tumoral accumulation of liposomes has been linked to an abnormal tumor microenvironment. Herein methods are presented to measure tumor microcirculation by perfusion imaging and elevated interstitial fluid pressure (IFP) using an image-guided robotic system. Measurements are compared to the intra-tumoral accumulation of liposomes, determined using volumetric micro-CT imaging.
FAQs
Water accumulation persists when removal pathways cannot match incoming or generated water. Drainage, evaporation, absorption, and deliberate removal each reduce the stored amount, whereas continued rainfall, runoff, infiltration, leakage, or condensation can replenish it. This balance explains why a site may remain wet even after an individual source stops, particularly when water has limited escape routes.
Surface slope and flow resistance determine how readily water moves away from a location. A slope can promote movement toward a drain or low point, while resistance can slow that movement and allow more water to remain. These variables help explain why nearby areas exposed to the same rainfall may experience different accumulation patterns.
Permeability and storage capacity influence whether water enters a material or remains at the surface. More permeable conditions can support absorption or groundwater movement, while available storage can temporarily hold water before drainage or removal. Considering both properties helps engineers evaluate where water may collect and how long the condition may persist.
Different water sources create different engineering concerns. Rainfall and surface runoff may load stormwater systems, while groundwater infiltration can affect foundations. Pipe leakage and condensation point to localized sources that require attention beyond weather alone. Linking the source to site characteristics supports more targeted design and helps reduce damage and flooding.
An engineering assessment begins by identifying the water source and the location where accumulation occurs. Engineers then consider slope, permeability, storage capacity, and flow resistance, along with available drainage, evaporation, absorption, or removal pathways. This structured review supports decisions about stormwater systems, foundations, roofs, roads, reservoirs, and flood-control infrastructure.
Water accumulation is relevant in engineering design because unmanaged water can contribute to erosion, corrosion, structural damage, flooding, and health risks. Engineers therefore incorporate its assessment into systems and structures such as roads, roofs, foundations, reservoirs, and flood-control infrastructure. This connects site water behavior with safety and service objectives.
Effective management supports resilient urban and environmental systems by matching design decisions to the way water moves and is retained at a site. Reducing accumulation can limit erosion, corrosion, structural damage, flooding, and health risks. The resulting assessment is therefore not limited to one structure; it also informs broader infrastructure planning and environmental protection.
