The video demonstrates the procedure for creating a mouse model to study neonatal hypoxic-ischemic brain injury. It outlines the steps for surgically inducing ischemia and subjecting the animal to hypoxia to exacerbate brain damage. Finally, it shows how to assess the resulting brain lesions, ensuring the mouse model is prepared for further scientific investigation.

We performed unilateral carotid artery occlusion on postnatal day 7-10 CD-1 mouse pups to create a neonatal hypoxic-ischemic (HI) model and investigated the effects of HI brain injury. We studied neurobehavioral functions in these mice compared to non-operated normal mice.

Here we describe a common method to induce chronic liver injury in mice by feeding of a choline-deficient and ethionine-supplemented (CDE) diet. We demonstrate health monitoring, liver perfusion, isolation, and preservation. A time course of six weeks can inform about liver injury, pathohistology, fibrosis, inflammatory, and liver progenitor cell responses.

FAQs
The initial insult reduces oxygen availability to hepatocytes, limiting ATP production. As energy stores fall, energy-dependent metabolic processes become impaired, and cell membranes lose integrity. This sequence explains why injury can develop rapidly when hepatic perfusion or oxygen delivery declines. It also connects biochemical changes in the liver to the severity of the patient’s circulatory state.
The centrilobular region is particularly susceptible to inadequate oxygen delivery during reduced hepatic perfusion. Consequently, this area can sustain damage when oxygen availability falls, making its vulnerability an important feature of the injury pattern. Recognizing this regional sensitivity helps explain why hepatocellular damage can become prominent during shock, severe hypoxemia, or other forms of circulatory failure.
Restoring blood flow does not necessarily end the injury process. Reperfusion can amplify hepatocellular damage through oxidative and inflammatory pathways after the period of oxygen deprivation. This means that both the interruption and restoration of circulation matter when evaluating the overall injury, particularly in clinical situations involving temporary blood-flow interruption followed by recovery.
A rapid, marked rise in aminotransferases is a characteristic clinical signal. Interpreted alongside shock, severe hypoxemia, or circulatory failure, this pattern can support recognition of ischemic liver injury rather than being viewed as an isolated liver abnormality. The timing and magnitude of the enzyme increase are therefore useful when assessing critically ill patients with suspected impaired hepatic oxygen delivery.
These settings may involve temporary interruption and subsequent restoration of hepatic or systemic blood flow. The mechanisms of oxygen deprivation and reperfusion are therefore directly relevant to perioperative liver assessment. Understanding them helps clinicians interpret postoperative hepatocellular damage and recognize how changes in circulation may affect the liver during transplantation, cardiac surgery, and related procedures.
The liver abnormality can serve as evidence of broader systemic hemodynamic compromise, not merely a local hepatic problem. Its occurrence may reflect inadequate circulation or oxygen delivery elsewhere in the patient’s critical illness. For this reason, recognizing the injury supports diagnosis and treatment decisions directed at the underlying circulatory disturbance while also guiding evaluation of liver damage.
