Article Abstract
In the past 20 years, near infrared spectrum technology has been widely used in human body monitoring due to its non-invasive and real-time characteristics. Oxygen, as the main metabolic substance of the human body, is consumed the most in brain tissue. In order to prevent complications caused by a decrease in brain tissue oxygen during treatment, the patient's brain tissue blood oxygen saturation needs to be monitored in real time. Currently, most of the clinically used non-invasive cerebral blood oxygen detection equipments use dual wavelengths. Other substances on the detection path will cause errors in the measurement results. Therefore, this article proposes a three-wavelength method based on the basic principle of non-invasive monitoring of cerebral blood oxygen using near-infrared spectrum. The brain tissue oxygen saturation monitoring method of detecting light sources was initially verified through the built system, laying the foundation for subsequent system engineering.

Major depressive disorder is a prevalent and debilitating psychiatric illness that produces significant disability. Clinical data suggest that the pathophysiology of depression is due, in part, to a dysregulation of inflammation and glutamate levels in the brain. The systemic administration of lipopolysaccharide (LPS) has been shown to induce depressive-like behaviors in mice.

Aims: Sustained neuroinflammation following ischemic stroke impedes post-injury tissue repairment and neurological functional recovery. Developing innovative therapeutic strategies that simultaneously suppress detrimental inflammatory cascades and facilitate neurorestorative processes is critical for improving long-term rehabilitation outcomes.
Methods: We employed a microglia depletion-repopulation paradigm by administering PLX5622 for 7 days post-ischemia; followed by a 7-day withdrawal period to allow microglia repopulation.

Brain aging is a major risk factor for cognitive decline and neurodegenerative diseases, driven by synaptic loss, reduced synaptic function, and inflammation. However, the molecular mechanisms underlying these dysfunctions remain unclear. Here, we conducted comparative transcriptomic analyses of brain regions (cortex and hippocampus) and kidney tissues, a peripheral organ with documented age-related dysfunction.

While these immune responses help to fight pathogens, they can also cause irreversible damage because of the CNS's limited regenerative capacity. Therefore, it is crucial to understand which CNS cells contribute to pathogen clearance but in doing so potentially damage surrounding tissue.

Background: This study investigates the impact of trimethylamine oxide (TMAO) on recurrent cerebral infarction in minor ischemic stroke (MIS).
Methods: A rat model was used, with dietary choline levels adjusted to vary TMAO levels. TMAO was quantified via liquid chromatography-mass spectrometry (LC-MS), and histological changes in brain and aortic tissues were analyzed using HE staining.
