Tannic Acid Mitigates Monosodium Glutamate‐Induced Cortical Damage by Modulating Synaptic and Calcium‐Related Gene and Protein Expression

Journal of Applied Toxicology, EarlyView.
ABSTRACT Neurotoxicity induced by excessive glutamatergic signaling is associated with synaptic dysfunction, calcium imbalance, and oxidative stress, which are key molecular events implicated in several neurodegenerative conditions. Monosodium glutamate (MSG), a common flavor enhancer, may exert neurotoxic effects, particularly on synaptic integrity ...

Is the Cognitive Ability of Fawn‐Footed Mosaic‐Tailed Rat Melomys cervinipes Offspring Related to Mothers’ Care or Cognitive Abilities?

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The cognitive abilities of many non‐human animals have been investigated in recent years; however, outside of laboratory rodent strains, it is largely unknown how direct and indirect genetic factors influence the development of cognition. In a previous study, we found no impact of maternal genetic or non‐genetic effects on problem solving in ...

Alterations in brain metabolites in rats with experimental periodontitis: A metabolomic approach

Journal of Periodontology, EarlyView.
Abstract Background Periodontitis (PD) is a chronic inflammatory disease with systemic effects. Emerging evidence suggests a link between periodontal inflammation and neurological changes, but the biochemical mechanisms in key brain regions, such as the hippocampus and amygdala, remain unclear.

Expedients for the ethical use of Rattus norvegicus as live prey in Wildlife Sanctuaries. A case study. [PDF]

openWildlife sanctuaries play a pivotal role in conserving and rehabilitating various species which often require live prey, such as rats, to provide natural feeding methods to resident predators. These predator-prey dynamics are also fundamental for the
