Alzheimer's disease (AD) is the most common form of dementia with complex causes and limited treatment options. Recent research has suggested a connection between the progression of AD and the activity of gut microbiota. Ginger, a plant known for its anti-inflammatory, antioxidant, and neuroprotective properties, has gained attention as a potential treatment for alleviating AD symptoms.

Also, in ASD, several accompanying disorders such as anxiety are observed. Considering the important role of amygdala in the pathophysiology of ASD, the present study focused on the neuronal changes and it possible signaling pathway in amygdala.

Besides behavioral defects, these individuals also suffer from various associated disorders such as gastrointestinal deficit, altered gut microbiota composition and their metabolite. This study examined the effect of ALC on microbiota SCFA production and its effects on brain inflammation in VPA autism model.

Klotho, an anti-aging protein, alleviates oxidative stress by activating the transcription of an important antioxidant enzyme, manganese superoxide dismutase (MnSOD), in the nervous system. Thus, increased Klotho expression level could lead to a reduction in neuronal damages after brain ischemia via lowering oxidative stress.

KA induces excitotoxicity (especially in the acute phase of the disease), which leads to neurodegeneration and epileptogenesis through oxidative stress and inflammation. Ferulic acid (FA) is one of the well-known phytochemical compounds that have shown potential antioxidant and anti-inflammatory properties and promise in treating several diseases.

Accumulating evidence has suggested that inflammation participates in the progression and pathogenesis of epilepsy. During inflammation, a cytosolic multimolecular complex called the "inflammasome" is activated, driving the innate immune response.

In the present study, we investigated the effect of DBS in the LH during the extinction phase of morphine CPP.
Materials And Methods: Rats were implanted with electrodes in the LH and went through conditioning trials for morphine CPP (40 min each, for three days), followed by extinction trials (20 min, for nine days).
Background: Hippocampal aromatase is responsible for local synthesis of 17β-estradiol (E2) that has much higher concentrations than serum levels in males and females. Letrozole, an aromatase inhibitor, passes through the brain barriers, distributes to the brain, and affects local E2 synthesis. Here, the effects of intra-cerebroventricular (ICV) letrozole administration in the presence and absence of gonads were examined on the cognitive abilities of male and female rats.

The major cause of AD is extensive oxidative stress and inflammation in central nervous system (CNS). Vitamin D and E are the most known vitamins that control oxidative stress and mitochondrial respiratory function.

Rosmarinic Acid (RA) is a natural polyphenolic compound with antioxidant, anti-apoptotic, anti-neurodegenerative, and anti-inflammatory properties.

Probiotics are microorganisms that are believed to be beneficial to human and animals. Probiotics reduce oxidative stress and inflammation in some cases.

Adipose tissue mesenchymal stem cells (ATSCs) secret many neurotrophic and anti-inflammatory factors called conditioned medium (CM). Many studies have demonstrated that CM of mesenchymal stem cells facilitate regeneration and attenuates inflammation in many disorders.

Objectives: The beneficial outcomes of bone marrow-derived mesenchymal stem cell (BMSC) treatment on functional recovery following stroke has been well established. Furthermore, 5-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors have also been shown to increase neuronal survival and promote the movement of BMSCs towards the sites of inflammation. However, the precise mechanisms mediating the improved neurological functional recovery in stoke models following a combination treatment of Simvastatin and BMSCs still remained poorly understood.

Material And Methods: A systematic literature search was conducted, including database searches in PubMed, Medline, Embase, ScienceDirect, Scopus, ISC, Health, Web of Science, and the Cochrane Library Database of relevant articles, personal files and systematic reviews to identify studies examining risk factors in epilepsy.
Objectives: Post-traumatic stress disorder (PTSD), one of the most devastating kinds of anxiety disorders, is the consequence of a traumatic event followed by intense fear. In rats with contextual fear conditioning (CFC), a model of PTSD caused by CFC (electrical foot shock chamber), deep brain stimulation (DBS) alleviates CFC abnormalities.
Materials And Methods: Forty Male Wistar rats (220-250 g) were divided into 5 groups (n=8) and underwent stereotactic surgery to implant electrodes in the right basolateral nucleus of the amygdala (BLn).
Despite extensive research over the years, there still exists some debate as to what constitutes the optimal therapeutic strategy to promote recovery following stroke. Due to the complexity of injured brain pathophysiology, treatment approaches should ideally address numerous factors, ultimately aiming to promote tissue protection, axonal regrowth and functional recovery. This study extends the understanding of the effects of bone marrow stromal cell (BMSC) treatment following experimentally induced ischemic stroke in rats.
