Disrupted neuregulin 1-ErbB4 signaling: Consequences of prenatal morphine exposure in rat pups and molecular gateway to neurological impairment.

Objective: Morphine exposure during pregnancy has detrimental effects on both the mother and her offspring, both during and after childbirth. This study aimed to investigate the impact of prenatal morphine exposure on rat pups and dams, specifically focusing on changes in Neuregulin-1 (Nrg-1)/ErbB4 gene expression, inflammation, and brain-derived neurotrophic factor (BDNF) levels.

Materials And Methods: Twenty female rats were randomized into two experimental groups:1-Morphine Group: Dams received morphine throughout pregnancy.

Impact of social isolation on corticosterone release and recovery after stroke in aged rats: A behavioral and biochemical analysis.

Social isolation (SI) after stroke reduces recovery. The aim of this study was to evaluate the effects of SI on corticosterone release and recovery after stroke in aged rats. A total of 64 male Wistar rats (aged 24 months) were used in the present study.

Effects of moderate intensity training and lithium on spatial learning and memory in a rat model: The role of SIRT3 and PGC1-α expression levels and brain-derived neurotropic factor.

In this study we investigated the potential synergistic effects of moderate interval training (MIT) and lithium on spatial learning and memory. Forty-two male Wistar males were classified into six groups including I: Control, II: 10 mg/kg/day IP lithium (Li10), III: MIT, IV: Li10 + MIT, V: 40 mg/kg/day IP lithium (Li40), and VI: Li40 + MIT. Then, the rats underwent Morris Water Maze (MWM) test to assess their spatial memory and learning ability.
