Article Abstract
High-resolution computed tomography (CT) imaging of a live animal within a lead-lined synchrotron light hutch presents several unique challenges. In order to confirm that the animal is under a stable plane of anaesthesia, several physiological parameters (e.g. heart rate, arterial oxygen saturation, core body temperature and respiratory rate) must be remotely monitored from outside the imaging hutch. In addition, to properly scan the thoracic region using CT, the animal needs to be held in a vertical position perpendicular to the fixed angle of the X-ray beam and free to rotate 180°-360°. A new X-ray transparent mouse restraint designed and fabricated using computer-aided design software and three-dimensional rapid prototype printing has been successfully tested at the Biomedical Imaging and Therapy bending-magnet (BMIT-BM) beamline at the Canadian Light Source.

Mechanisms underlying cardiovascular, affective, and metabolic (CAM) multimorbidity are incompletely defined. We assessed how two risk factors-chronic stress (CS) and a Western diet (WD)-interact to influence cardiovascular function, resilience, adaptability, and allostatic load (AL); explore pathway involvement; and examine relationships with behavioral, metabolic, and systemic AL. Male C57Bl/6 mice (8 weeks old, n = 64) consumed a control (CD) or WD (12%-65%-23% or 32%-57%-11% calories from fat-carbohydrate-protein) for 17 weeks, with half subjected to 2 h daily restraint stress over the final 2 weeks (CD + CS and WD + CS).

Ethnopharmacological Relevance: Jiao-tai-wan (JTW) is a classical traditional Chinese medicine formula that has long been used to treat insomnia. Recent pharmacological studies have highlighted its potential antidepressant effects. However, its role in regulating neuroinflammation associated with depression and the underlying mechanisms remains unclear.

Purpose: This study aimed to elucidate the role of lateral hypothalamic area (LHA) Vglut2 neurons in stress-induced intestinal inflammation and to investigate the underlying mechanisms involving neuro-immune interactions. Specifically, we hypothesized that LHA Vglut2 neuron activation exacerbates intestinal inflammation via sympathetic-driven IL-1β and Cxcl1 signaling.
Methods: Transgenic mice (Vglut2-cre) and wild-type controls were subjected to chronic restraint stress (CRS).

Objectives: Wuling powder has been widely used for the clinical treatment of IBS-D, but the microecological mechanism has not been found. This study aimed to investigate the regulatory effect of Wuling powder on intestinal mucosal microbiota in mice with diarrhea predominant-irritable bowel syndrome (IBS-D) by 16S rRNA high-throughput sequencing.
Methods: Mice were randomly divided into normal control group (Mc), model control group (Mm), and treatment group (Mt).
