Source: Michael G. Benton and Kerry M. Dooley, Department of Chemical Engineering, Louisiana State University, Baton Rouge, LA The Spin-and-Chill uses heat transfer and fluid flow fundamentals to chill beverages from room temperature to 38 °F in as little as 2 min. It would take a refrigerator approximately 240 min and an ice chest approximately 40 min to achieve an equivalent temperature change. This is accomplished Spin and Chill by spinning a can or bottle at up to 500 rpm, which creates...

A Hypertonic Saline Injection Technique for Inducing Glaucoma in Rats
0 Views •
2025
This video demonstrates glaucoma induction in an anesthetized rat by injecting hypertonic saline into the episcleral vein. The saline enters the trabecular meshwork via Schlemm's canal, causing tissue scarring, which blocks aqueous humor outflow and raises intraocular pressure. The elevated pressure damages retinal ganglion cells, leading to glaucoma.

Embryonic stages are the most susceptible to xenobiotics. Although chemical toxicity depends on salinity, no method exists to test the salinity dependence of toxicity to aquatic organisms. Here, we describe a new and high-throughput method for determining the salinity dependence of toxicity to aquatic embryos.

Saline Lavage for Sampling of the Canine Nasal Immune Microenvironment

2024
Saline nasal lavage can be used to sample the canine nasal immune microenvironment. Because the approach is relatively non-invasive and does not disrupt the nasal tissues, it can be performed serially. Cells and proteins collected from the nasal lavage technique can be processed for various laboratory analyses.
FAQs
Two protective effects work together: sodium chloride helps limit osmotic shifts, while cooling reduces cellular metabolism and enzymatic activity. This combination can slow physiological changes that would otherwise occur during handling. The result is better preservation of tissue, cell, or specimen condition over short intervals, supporting more consistent preparation before analysis, imaging, or processing.
The saline component addresses osmotic conditions rather than temperature itself. By helping maintain osmotic balance, it can reduce changes associated with exposing cells or tissues to an unsuitable aqueous environment. Cooling then contributes a separate stabilizing effect by slowing metabolic and enzymatic activity, so both concentration and temperature are relevant to maintaining biological material during short-term handling.
Reduced temperature slows cellular metabolism and enzymatic activity, which limits the rate of physiological changes in biological material. This matters when tissues, cells, or specimens must remain stable during collection, dissection, rinsing, or preparation. The cooling effect supports short-term control of the specimen state, but its role is primarily to slow change during handling rather than replace downstream processing.
Chilled Saline may be incorporated during tissue collection, dissection, rinsing, and temporary specimen storage. In each setting, it provides a controlled aqueous environment while the material is being handled. These uses are especially relevant when researchers need to preserve structural or biochemical stability before moving the specimen to later analysis, imaging, or processing steps.
Researchers may choose it when biological material must be maintained briefly between collection and a subsequent laboratory step. Its combined osmotic and temperature-related effects help limit physiological changes during that interval. This makes it relevant when the condition of tissues, cells, or specimens could influence later structural examination, biochemical analysis, imaging, or other processing outcomes.
Using a cooled saline solution can make specimen preparation more consistent by controlling two important handling conditions: osmotic environment and temperature. Limiting changes in structural and biochemical state helps reduce variation introduced before downstream work begins. In biology, this is useful for obtaining more comparable material across collection, dissection, rinsing, temporary storage, and subsequent analysis.
