Prolonged intermittent theta burst stimulation restores the balance between A2AR- and A1R-mediated adenosine signaling in the 6-hydroxidopamine model of Parkinson's disease.

JOURNAL/nrgr/04.03/01300535-202507000-00027/figure1/v/2024-09-09T124005Z/r/image-tiff An imbalance in adenosine-mediated signaling, particularly the increased A2AR-mediated signaling, plays a role in the pathogenesis of Parkinson's disease. Existing therapeutic approaches fail to alter disease progression, demonstrating the need for novel approaches in PD.

Intermittent theta burst stimulation attenuates oxidative stress and reactive astrogliosis in the streptozotocin-induced model of Alzheimer's disease-like pathology.

Introduction: Intracerebroventricularly (icv) injected streptozotocin (STZ) is a widely used model for sporadic Alzheimer's disease (sAD)-like pathology, marked by oxidative stress-mediated pathological progression. Intermittent theta burst stimulation (iTBS) is a noninvasive technique for brain activity stimulation with the ability to induce long-term potentiation-like plasticity and represents a promising treatment for several neurological diseases, including AD. The present study aims to investigate the effect of the iTBS protocol on the animal model of STZ-induced sAD-like pathology in the context of antioxidant, anti-inflammatory, and anti-amyloidogenic effects in the cortex, striatum, hippocampus, and cerebellum.

Intermittent Theta Burst Stimulation Ameliorates Cognitive Deficit and Attenuates Neuroinflammation PI3K/Akt/mTOR Signaling Pathway in Alzheimer's-Like Disease Model.

Neurodegeneration implies progressive neuronal loss and neuroinflammation further contributing to pathology progression. It is a feature of many neurological disorders, most common being Alzheimer's disease (AD). Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive stimulation which modulates excitability of stimulated brain areas through magnetic pulses.

Downregulation of CD73/AR-Mediated Adenosine Signaling as a Potential Mechanism of Neuroprotective Effects of Theta-Burst Transcranial Magnetic Stimulation in Acute Experimental Autoimmune Encephalomyelitis.

Multiple sclerosis (MS) is a chronic neurodegenerative disease caused by autoimmune-mediated inflammation in the central nervous system. Purinergic signaling is critically involved in MS-associated neuroinflammation and its most widely applied animal model-experimental autoimmune encephalomyelitis (EAE). A promising but poorly understood approach in the treatment of MS is repetitive transcranial magnetic stimulation.

Transcranial theta-burst stimulation alters GLT-1 and vGluT1 expression in rat cerebellar cortex.

Repetitive transcranial magnetic stimulation (rTMS) induces changes in expression of proteins engaged in activity of excitatory and inhibitory systems as well as redox homeostasis. Our aim was to investigate the effect of single (SS) and repeated session (RS) of intermittent and continuous theta-burst stimulation (iTBS; cTBS) on the expression of vesicular and plasmatic glutamate transporters 1 (vGluT1 and GLT-1), glial fibrillary acidic protein (GFAP) and influence on oxidative status in rats cerebellar tissue and plasma. Redox state parameters in cerebellar tissue and plasma were assessed 24 h after single and 48 h after the last TBS session.

Opportunities for Guided Multichannel Non-invasive Transcranial Current Stimulation in Poststroke Rehabilitation.

Stroke is a leading cause of serious long-term disability worldwide. Functional outcome depends on stroke location, severity, and early intervention. Conventional rehabilitation strategies have limited effectiveness, and new treatments still fail to keep pace, in part due to a lack of understanding of the different stages in brain recovery and the vast heterogeneity in the poststroke population.

Oxime and atropine failure to prevent intermediate syndrome development in acute organophosphate poisoning.

Introduction: Intermediate syndrome (IMS) was described a few decades ago, however, there is still a controversy regard ing its exact etiology, risk factors, diagnostic parameters and required therapy. Considering that acute poisonings are treated in different types of medical institutions this serious complication of organophosphate insecticide (OPI) poison ing is frequently overlooked. The aim of this paper was to present a case of IMS in organophosphate poisoning, which, we believe, provides additional data on the use of oxime or atropine.
