Changes in microcirculation variables in an acute endotoxaemic equine model.
Equine Vet J
January 2025
Clinic for Horses, University of Veterinary Medicine Hannover, Foundation, Hannover, Germany.
Background: Microcirculation is the essential link between macrocirculation and cellular metabolism.
Objectives: To test our hypotheses that microcirculation variables will show a heterogeneous flow pattern during experimental endotoxaemia, and that fluid therapy and noradrenaline (NA) infusion will normalise altered microcirculation variables.
Study Design: In vivo experiments.
Evaluating the Efficacy of Levetiracetam on Non-Cognitive Symptoms and Pathology in a Tau Mouse Model.

Alzheimer's disease (AD) is marked by amyloid-β plaques and hyperphosphorylated tau neurofibrillary tangles (NFTs), leading to cognitive decline and debilitating non-cognitive symptoms. This study aimed to evaluate compounds from four different classes in a short-term (7-day) study using transgenic tau mice to assess their ability to reduce non-cognitive symptoms. The best candidate was then evaluated for longer exposure to assess non-cognitive symptoms, cognition, and pathology.

Migration is an essential characteristic of cells that occurs during many physiological and pathological processes. Astrocytes represent the most abundant cell type in the adult central nervous system (CNS), that play a crucial role in various functions such as guiding and supporting neuronal migration during development and maintaining brain homeostasis at adulthood. Astrocytes specifically synthesize and release endozepines, a family of regulatory peptides, including the octadecaneuropeptide (ODN).

Insomnia is a mental disorder in which drugs only alleviate the symptoms but also produce adverse effects. Therefore, developing innovative sedative-hypnotic agents is urgent. In this work, twenty-five novel heteroatomic compounds were designed, synthesized, and screened for their sedative activities, structurally featuring the fusion of pyrimidine and carbazole or benzothiazole.
