In humans, pyruvate dehydrogenase complex (PDC) deficiency impairs brain energy metabolism by reducing the availability of the functional acetyl‑CoA pool. This “hypometabolic defect” results in congenital lactic acidosis and abnormalities of brain morphology and function, ranging from mild ataxia to profound psychomotor retardation. Our previous study showed reduction in total cell number and dendritic...
The brain endocannabinoid system has been shown to play a role in many physiological processes, including mood, learning and memory. It is also involved in the pathogenesis of anxiety, depression, mood disorders, as well as neurodegenerative disorders, although the exact mechanisms by which cannabinoid receptors interfere in these disorders are not well established. The aim of the present study was...
Alzheimer’s disease (AD) has become the most prevalent neurodegenerative disorder. Given the pathogenesis of AD is unclear, there is currently no drug approved to halt or delay the progression of AD. Therefore, it is pressing to explore new targets and drugs for AD. In China, polyphenolic Chinese herbal medicine has been used for thousands of years in clinical application, and no toxic effects have...
The cerebellum is a potent anti‑epileptic target for deep brain stimulation in patients with drug‑resistant epilepsy. The effects of such stimulation, however, may also favor seizure activity. Our goal was to investigate the effect of cerebellar electrical stimulation (ES) alone and in combination with the anti‑epileptic drug diazepam (DIA) on seizure outcome. We used a rat model of pentylenetetrazol...
Neurodegeneration in Parkinson’s disease (PD) includes processes of chronic inflammation and oxidative stress which are related to dysregulation in the homeostasis of iron metabolism. Hepcidin is a peptide hormone responsible for systemic iron homeostasis and simultaneously the inflammatory response protein, induced in response to interleukin 6 (IL‑6). We assessed the serum concentration of hepcidin...
The studies aimed to determine the antidepressant efficacy of single and chronic administration of dapoxetine alone and vortioxetine alone, as well as in the combination of these drugs. An additional objective of the study was to measure the effect of the active substances on the corticosterone level in chronically stressed animals. The study was conducted on male Wistar rats using non‑stressed and...
Neuromyelitis optica also known as Devic’s syndrome is a rare autoimmune disorder that predominantly targets the optic nerves and the spinal cord. It is a debilitating disorder that damages a person’s health. Initially it was considered as a variant of multiple sclerosis (MS). But, in 2004, a water channel protein associated antibody was found to be responsible for the disease. This helped in distinguishing...
Diabetes is a metabolic disorder characterized by hyperglycemia and impaired insulin secretion or action. Psychological comorbidities, such as depression and anxiety, are more common in people with diabetes. Exercise results in anxiolytic effects, as demonstrated in numerous studies. This study aims to evaluate potential anxiolytic effects of aerobic exercise in streptozotocin (STZ)‑induced diabetes...
Anxiety is a complex psychological state which happens after stressful life experiences. Many factors such as daily life events, neurotransmitter systems, and different brain areas could influence anxiety behavior in humans and animals. For example, opioids and androgens decrease anxiety behavior both in humans and animals. Furthermore, removing the testes (gonadectomy) causes higher levels of anxiety‑like...
The discovery and application of induced pluripotent stem cells (iPSCs) provide a novel treatment modality for diseases, which remain incurable. Particularly, in the treatment of neurodegenerative diseases such as Parkinson’s disease (PD), iPSC‑technology holds an interesting prospect for replacement therapy. Currently, the prognostic improvement of PD is limited and relies on symptomatic treatment...
