The content of total protein, glycoproteins, and N-acetylneuraminic acid in different membrane fractions of rat brain tissues was studied 60 min and 24 h following X-irradiation with a dose of 0.31 C/kg. A slight increase in the amount of glycoproteins was noted upon electrophoresis due to the occurrence of low molecular weight carbohydrate-containing proteins. The derangement of the membrane glycoprotein structure is supposed to be one on the causes of radiation destruction of membranes.

This study evaluates acetylcholinesterase (AChE) enzyme activity levels, oxidative stress parameters, histopathological findings, and serum melatonin levels in rat brain tissue. 32 male Wistar Albino rats were randomly divided into four groups: Control, Light, Dark, Dim light ( = 8 each group). After a 30 day experiment, brain tissues were collected to measure AChE, glutathione S-transferase (GST), glutathione (GSH), and malondialdehyde (MDA) levels and conduct histopathological analyses.

Cerebral Global Ischemia (CGI) is a devastating neurological condition affecting millions globally each year, leading to significant inflammatory responses and long-term consequences, including delayed neuronal death and neurocognitive impairment. Following brain injury, resident microglial cells are activated, triggering pro-inflammatory cytokine expression and altering neuroimmune processes in a sex-dependent manner, particularly within the hippocampus. Coumestrol, a plant estrogen, is promoted as an alternative to post-menopausal hormone therapy due to its various mechanisms that enhance brain health, including its anti-inflammatory effects.

Aim: The aim of this study was to compare the effects of dexmedetomidine, midazolam, propofol, and intralipid on lidocaine-induced cardiotoxicity and neurotoxicity.
Methods: Forty-eight male Sprague-Dawley rats were randomly divided into six groups (n = 8 per group): control (C), lidocaine (L), lidocaine + dexmedetomidine (LD), lidocaine + midazolam (LM), lidocaine + propofol (LP), and lidocaine + intralipid (LI). Dexmedetomidine (100 µg/kg), midazolam (4 mg/kg), propofol (40 mg/kg), and intralipid (10 mg/kg) were administered intraperitoneally as pretreatment.
Regulation of MAP2, GFAP, and calcium in the CA3 Region Following Kainic Acid Exposure to organotypic hippocampal slice culture.

Background: Neurodegeneration due to neurotoxicity is one of the phenomena in temporal lobe epilepsy. Experimentally, hippocampal excitotoxicity process can occur due to kainic acid exposure, especially in the CA3 area. Neuronal death, astrocyte reactivity and increased calcium also occur in hippocampal excitotoxicity, but few studies have investigated immediate effect after kainic acid exposure.

The sphingosine-1-phosphate-5 (S1P) receptor is one of the five membrane G protein-coupled receptors that are activated by the lysophospholipid, sphingosine-1-phosphate, resulting in regulation of many cellular processes. S1P receptors are located on oligodendrocytes and are proposed to influence oligodendrocyte physiology. Understanding S1P modulation during processes such as remyelination could have potential applications for demyelinating CNS disorders such as multiple sclerosis (MS).
