A pendant drop surface film balance implemented with a multi-subphase exchange, nicknamed the OCTOPUS, allows for mimicking digestive conditions by the sequential subphase exchange of the original bulk solution with simulated gastrointestinal fluids. The simulated in vitro digestion is monitored by recording in situ the interfacial tension of the digested interfacial layer.

Preparing an Antigen-Adjuvant Emulsion to Induce Autoimmune Encephalomyelitis

2025
This video demonstrates an efficient homogenization technique to generate an antigen-adjuvant emulsion to induce experimental autoimmune encephalomyelitis (EAE) in a murine model. The emulsion contains an autoantigen — myelin oligodendrocyte glycoprotein (MOG) — in the water phase, surrounded by a continuous oil phase comprising an inactivated pathogenic bacteria. The emulsion ensures a sustained release of antigens for a prolonged immune response.

We present an apparatus based on hot-wire ignition in a pressurized enclosure and an associated methodology to measure the minimum pressure required to induce sustained combustion in water-based emulsion explosives. This method improves product characterization to allow one to use them more safely during pumping and mixing operations.

Restriction Enzyme Digests

Restriction enzymes or endonucleases recognize and cut DNA at a specific sequence. These enzymes occur naturally in bacteria as a defense against bacteriophages - viruses that infect bacteria. Bacterial restriction enzymes cut the invading bacteriophage DNA while leaving the bacterial genomic DNA unharmed due to addition of methyl groups. This video explains the basic principles of restriction enzymes including: how restriction enzymes are named and the types of recognition sites and...

The assembly and positioning of the mitotic spindle depend on the combined forces generated by microtubule dynamics, motor proteins and cross-linkers. Here we present our recently developed methods in which the geometrical confinement of spherical emulsion droplets is used for the bottom-up reconstitution of basic mitotic spindles.
FAQs
Bile salts stabilize and subdivide dietary fat into smaller droplets within the aqueous gastrointestinal environment. This dispersion increases the total oil–water interface available to digestive enzymes, allowing pancreatic lipase greater access to triglycerides. Their action therefore improves the physical conditions for hydrolysis rather than chemically breaking down the fat themselves.
Pancreatic lipase hydrolyzes triglycerides at the oil–water interface, producing fatty acids and monoacylglycerols. Colipase assists lipase during this interfacial reaction, helping the enzyme function on the dispersed fat. Together, they connect droplet organization with the chemical conversion required for subsequent lipid transport and uptake.
The fatty acids and monoacylglycerols generated by hydrolysis associate with bile salts to form micelles. These structures transport the lipid products through the aqueous intestinal environment to intestinal cells, where uptake occurs. The cells can then reassemble the absorbed components, linking digestion, transport, and intracellular lipid processing.
The oil–water interface is the location where pancreatic lipase encounters dispersed triglycerides. Dividing fat into smaller droplets increases the amount of this accessible boundary, which can improve enzyme access and promote hydrolysis. In biochemistry, this illustrates how physical organization of substrates can strongly influence the efficiency of an enzymatic process.
Food design can use the relationship between droplet dispersion, bile-salt stabilization, enzyme access, and micelle formation to influence how dietary lipids become available for uptake. Understanding these linked stages helps researchers examine how an emulsion’s organization may affect lipid breakdown and absorption, supporting foods designed for controlled lipid availability.
The process demonstrates how dispersed materials interact with bile salts, enzymes, aqueous environments, and transport structures. These biochemical relationships are relevant to drug delivery because they provide a context for studying how compounds associated with dietary fat may be processed and transported during gastrointestinal digestion. The same principles also connect digestion research with formulation design.
