This protocol describes a custom overpressure air system designed to induce closed-system central nervous system (CNS) injuries in mice, including ocular, brain, and spinal cord traumas. The goal of this protocol is to provide a framework for researchers to easily adapt and expand the system for their unique CNS trauma studies.

This video demonstrates a method for high-resolution EEG recording in a rat model of focal epilepsy. It outlines the steps involved in preparing the rat, connecting a multichannel EEG mini-cap to the rat's scalp, and recording the EEG to identify seizure-related events characteristic of the epilepsy model.

The function of adult-born mammalian neurons remains an active area of investigation. Ionizing radiation inhibits the birth of new neurons. Using computer tomography-guided focal irradiation (CFIR), three-dimensional anatomical targeting of specific neural progenitor populations can now be used to assess the functional role of adult neurogenesis.

Intracellular Signaling Affects Focal Adhesions

Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active. Some...

Establishing a Focal Demyelination Mouse Model via a Two-Point Injection of Lysophosphatidylcholine
0 Views •
2025
This video demonstrates the generation of a focal demyelination mouse model using a two-point Lysophosphatidylcholine (LPC) injection. The skull of an anesthetized mouse is exposed. The injection coordinates are determined, and a hole is drilled to enable LPC injections at targeted sites. LPC induces focal demyelination of neurons via inflammation, while a two-point injection ensures its sustainability.
FAQs
The central mechanism is spatial control: imaging identifies the intended treatment zone, and the chosen energy or tissue-destructive method is directed at that zone rather than applied broadly across the organ. Thermal energy, freezing, radiation, or another modality can produce a local treatment effect while limiting exposure of nearby healthy structures.
Disease distribution helps determine whether a localized target can be treated appropriately. Focal therapy is intended for selected, localized tumors rather than disease patterns that cannot be addressed through a defined treatment area. Patient characteristics are considered alongside distribution, so treatment selection reflects both the lesion and the individual receiving care.
Preserving surrounding tissue can reduce unintended damage to adjacent structures compared with treatment that affects a larger region. This organ-sparing objective may also support a shorter recovery. These potential advantages depend on accurate targeting and appropriate case selection, because local treatment must still adequately address the diseased tissue.
Planning begins with imaging to identify and define the diseased area. Clinicians then select a suitable localized modality, such as thermal energy, freezing, radiation, or another tissue-destructive method, and direct it at the target. Careful treatment planning is followed by clinical follow-up to assess the course after treatment.
In oncology, the approach is used most notably for selected localized tumors. The overview identifies prostate and liver lesions as important examples, provided disease distribution and patient characteristics make organ-sparing treatment appropriate. Its use therefore depends less on the organ name alone than on whether the disease can be addressed as a defined target.
Localized treatment can eliminate or control a lesion, but its suitability depends on matching the technique to the disease pattern and the patient. Careful selection helps identify cases in which the target can be treated appropriately, while follow-up remains necessary after the procedure to support ongoing clinical assessment and management.
