Micro-computed tomography (micro-CT) coupled with tissue, or vascular, specific contrast agent has emerged as a powerful tool for detecting and monitoring tumor growth in the liver of murine animals. Intravenous injections of contrast agents can be technically challenging and lead to errors that can considerably influence the outcome of a preclinical study, prompting an alternative method. Here we assessed the effectiveness of intraperitoneal injections of polyiodinated triglycerides emulsions (Fenestra LC) in micro-CT imaging of young SCID (8 weeks) and old BALB/c (48 weeks) mice with xenograft or carcinogen-induced liver tumors, respectively, and determined an optimal acquisition time. Utilizing an intraperitoneal injection is a viable alternative administration route for using Fenestra in detection and quantification of murine liver tumor burden.

Binge drinking (BD) is a widespread pattern of excessive alcohol consumption among adolescents and young adults with detrimental consequences for brain development. Animal models are essential for investigating the neurobiological mechanisms underlying BD, but selecting an appropriate model is critical to ensure relevance to human behavior. This study aims to validate a murine model of (BD) using Swiss Webster mice.

Parkinson's disease (PD) is characterized by impairments in motor control following the degeneration of dopamine-producing neurons located in the substantia nigra pars compacta. Environmental pesticides such as Paraquat (PQ) and Maneb (MB) contribute to the onset of PD by inducing oxidative stress (OS). This study evaluated the therapeutic efficacy of moderate physical activity (PA) on both motor and non-motor symptoms in a Wistar rat model of Paraquat and Maneb (PQ/MB) induced PD.

Adolescence is a period of heightened neuroplasticity and vulnerability to environmental insults, including drug exposure. In this study, we investigated the short- and long-term behavioral effects, as well as the long-term hippocampal effects, of chronic cocaine administration during adolescence, along with the potential neuroprotective role of insulin-like growth factor 2 (IGF2) in male C57BL/6J mice. Over 21 days, mice received daily intraperitoneal injections of saline, cocaine, IGF2, or a combination of cocaine and IGF2.

Objectives: To investigate the therapeutic mechanism of 2,6-dimethoxy-1,4-benzoquinone (DMQ) for alleviating dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) in mice.
Methods: Eighteen male C57BL/6J mice were equally randomized into control group, DSS group and DMQ treatment group. In DSS and DMQ groups, the mice were treated with DSS in drinking water to induce UC, and received intraperitoneal injections of sterile PBS or DMQ (20 mg/kg) during modeling.

Objectives: To investigate the therapeutic effect of acupuncture in a rat model of insomnia and its regulatory effect on the glutamic acid (Glu)/γ-aminobutyric acid (GABA)-glutamine (Gln) metabolic loop.
Methods: Forty male SD rats were randomly assigned to control group, model group, group and group (=10). In the latter 3 groups, rat models of insomnia were established by intraperitoneal injections of p-chlorophenylalanine and verified using a sodium pentobarbital-induced sleep test.
