Source: David C. Powers, Tamara M. Powers, Texas A&M In this video, we will carry out the photochemically initiated polymerization of styrene to generate polystyrene, which is an important commodity plastic. We will learn the fundamentals of photochemistry and use simple photochemistry to initiate radical polymerization reactions. Specifically, in this module we will examine the photochemistry of benzoyl peroxide and its role as a photo-initiator of styrene polymerization reactions. In the...

Interference Reflection Microscopy for Label-Free Visualization of Microtubule Dynamics

In this video, we describe the interference reflection microscopy (IRM) technique to visualize microtubules growing on a coverslip surface in the presence of a suitable buffer. Upon illumination with incident light, the coverslip-buffer interface and buffer-microtubule interface reflect light, which combines to create an interference pattern, enabling the visualization of microtubules as high-contrast images against a bright background.

This paper describes a protocol that assesses the changes of myofilament Ca2+ sensitivity during contraction in isolated cardiac myocytes from rat heart. Together with cardiac electrophysiology, systolic/diastolic cytosol Ca2+ levels and contraction/relaxation, this measurement is imperative in underpinning the mechanisms mediating cardiac excitation-contraction coupling in healthy and diseased hearts.

Encapsulation of Cancer Therapeutic Agent Dacarbazine Using Nanostructured Lipid Carrier

The most commonly used method for nanostructured lipid carrier (NLC) synthesis involves oil-in-water emulsion, homogenization and solidification. This was modified here by applying high shear dispersion after solidification to achieve a NLC with desirable size, improved drug encapsulation and drug loading efficiency as a potential carrier for dacarbazine delivery.
FAQs
Poloxamer 407 forms micelles when its concentration rises above a critical concentration, meaning the threshold at which individual polymer molecules begin to assemble. Its amphiphilic structure drives this organization, with polyethylene oxide regions interacting with water and the polypropylene oxide region supporting aggregation. Micelle formation can improve the solubility and handling of incorporated pharmaceutical or biological agents.
Increasing temperature promotes closer packing of Poloxamer 407 micelles, allowing the formulation to undergo reversible gel formation. This temperature-responsive behavior can help a preparation remain easier to handle before administration and become more structured afterward. Because the gelation is reversible, temperature acts as an important condition for controlling local retention and release behavior.
The degree of micelle packing influences how readily an incorporated agent moves through the formulation. More closely packed micelles can support a more structured gel state, which may prolong local residence and contribute to controlled release. This relationship is important when designing formulations intended to sustain exposure to antimicrobial or immune-modulating compounds at a target tissue.
Concentration and temperature are central variables because they govern micelle formation, micelle packing, and reversible gel behavior. These conditions influence solubility, formulation stability, local residence, and release of the incorporated agent. Adjusting them is therefore relevant when developing injectable, topical, or mucosal preparations for biological or pharmaceutical delivery.
A study can begin by incorporating an antimicrobial or immune-modulating compound into a Poloxamer 407 formulation, then selecting conditions that support the desired solubility and stability. The preparation can be designed for injectable, topical, or mucosal delivery. Researchers can subsequently examine whether the formulation prolongs local residence and sustains exposure at the target tissue.
Poloxamer 407 is useful when an antimicrobial compound needs prolonged local exposure rather than rapid loss from the administration site. Its formulation properties can support injectable, topical, or mucosal delivery and help control release. In infection research, this enables investigation of whether delivery conditions affect treatment effectiveness and the persistence of antimicrobial activity at target tissues.
In immunology research, Poloxamer 407 can serve as a delivery platform for immune-modulating compounds. By influencing solubility, stability, release, and local residence, the formulation helps researchers study how exposure conditions shape immune responses. This approach connects material behavior with biological outcomes, particularly when the compound must remain near a selected tissue or mucosal site.
Researchers can evaluate whether the formulation improves solubility or stability, forms the intended reversible gel under the selected temperature conditions, and provides controlled release. They can also assess local residence and exposure of antimicrobial or immune-modulating agents. Together, these outcomes show whether the delivery design is likely to influence treatment effectiveness or immune responses in the studied setting.
