Caffeine abrogates oxidative stress imbalance: Its implication on lateral geniculate nucleus and visual cortex following hyaluronic acid exposure.

This study assessed the role of caffeine (adenosine receptor antagonist) in the Lateral geniculate body as well as the primary visual cortex of hyaluronic acid model of glaucomatous rats. Twenty (20) male Long evans rats were randomly divided into four groups with five animals each. This research confirmed that hyaluronic acid (HA) significantly induces elevated intraocular pressure from 18 to 35 mmHg and caffeine had no effect on its reduction to palliate visual impairment; There were a significant increase in the lipid peroxidation and conversely decrease in superoxide level with HA which were attenuated by caffeine.

Exposure to radio-frequency electromagnetic waves alters acetylcholinesterase gene expression, exploratory and motor coordination-linked behaviour in male rats.

Humans in modern society are exposed to an ever-increasing number of electromagnetic fields (EMFs) and some studies have demonstrated that these waves can alter brain function but the mechanism still remains unclear. Hence, this study sought to investigate the effect of 2.5 Ghz band radio-frequency electromagnetic waves (RF-EMF) exposure on cerebral cortex acetylcholinesterase (AChE) activity and their mRNA expression level as well as locomotor function and anxiety-linked behaviour in male rats.
