Background: Coronavirus disease 2019 (COVID-19) has spread worldwide and poses a great threat to global health. COVID-19 has also an unneglected effect on migraine patients. Migraine attack frequency is one of the migraine characteristics, and its impact during COVID-19 needs further research. We aimed to evaluate whether migraine attack frequency during the COVID-19 pandemic differed from pre-COVID-19 Read More

Objective: Major Depressive Disorder (MDD) is a major health problem worldwide. Estrogen interacts with the central nervous system and has been shown to affect anxiety and depressive behavior. Estrogen mediates its effects by connecting its receptors, estrogen receptors 1 and 2. The purpose of this case-control study was to clarify the association between MDD risk and estrogen receptor 1 (ESR1) gene variants. Metho Read More

Background: Previous studies have reported that mesenchymal stem cell (MSC)- derived exosomes can protect primary rat brain microvascular endothelial cells (BMECs) against oxygen-glucose deprivation and reoxygenation (OGD/R)-induced injury. Objective: The aim was to identify the key factors mediating the protective effects of MSC-derived exosomes. Methods: Primary rat BMECs were either pretreated or not pretreate Read More

Introduction: Susceptibility-Eeighted Imaging (SWI) enables visualization of thrombotic material in acute ischemic stroke. We analyzed the association between thrombus length on SWI and the success rate of recanalization in stent-retriever mechanical thrombectomy. Methods: A retrospective study was performed on 128 patients with Middle Cerebral Artery (MCA) thrombus on pretreatment SWI. The patients wer Read More

Background: Neovascular age-related macular degeneration (AMD) with choroidal neovascularization (CNV) is a leading cause of blindness in elderly people. Anti-vascular endothelial growth factor (anti-VEGF)-drugs are used to treat AMD patients; however, some patients are resistant to these therapies. Objective: The purpose of this study was to investigate the anti-angiogenic effects of α2-adrenergic agonists, including Read More

Objective: Our study investigated the association between the level of HbA1c (glycated hemoglobin) at admission and the prognosis of aneurysmal subarachnoid hemorrhage (SAH). Methods: A total of 510 patients treated with neuro-intervention for aneurysmal SAH and with data for admission HbA1c (glycated hemoglobin) were included. Favorable clinical outcome was defined as modified Rankin Scale (mRS) score of 0-2 at 3 Read More

Background: Parkinson’s disease (PD) is a neurodegenerative disorder caused by the progressive loss of dopaminergic neurons. Canopy fibroblast growth factor signaling regulator 2 (CNPY2) is down-regulated in this disease, but its functions are unknown. Objective: This study investigates the effects and regulation of CNPY2 in the apoptosis of neurons in PD. Methods: We established a PD model in vivo by a five consecutive day Read More

Background and Purpose: Reduced number and function of CD31+ circulating angiogenic cells (CACs) may explain vascular complications associated with the chronic phase stroke. The purpose of this study was to quantify CD31+ CAC paracrine function, total number and number of various subtypes of CD31+ CACs in individuals with chronic stroke compared with controls. Methods: Peripheral blood mononuclear cells Read More

Objective: A retinal vein occlusion (RVO) is a relatively common retinal vascular disorder, especially in the elderly. Many experiments have been performed on patients with an RVO but performing any type of experiments and especially longitudinal experiments on humans is difficult, if not impossible, on ethical grounds. Therefore, we have created a retinal vein occlusion (RVO) model by laser irradiation of cynomolgus mon Read More

Neurodegenerative disorders impact more than one billion individuals worldwide and are intimately tied to metabolic disease that can affect another nine hundred individuals throughout the globe. Nicotinamide is a critical agent that may offer fruitful prospects for neurodegenerative diseases and metabolic disorders, such as diabetes mellitus. Nicotinamide protects against multiple toxic environments that include reac Read More

Lipoprotein disorders are a major risk factor for atherosclerotic neuro-cardiovascular disease (ACVD) and are heavily influenced by lifestyle, including alcohol drinking. Moderate drinkers have a lower ACVD risk than abstainers due to their higher levels of high-density lipoprotein (HDL) cholesterol, an important protective factor against ACVD. On the contrary, heavy drinking increases ACVD risk. According to an extensiv Read More

Background: Robust evidence has described that Parkinson´s disease (PD) is associated with an increased risk for developing epileptic seizures. In fact, an interplay between PD and epilepsy has been of interest for many years. An emerging hypothesis is that inflammation could link both diseases. Objective: Bearing in mind the experience of our group in the field of Ca2+/cAMP signalling pathways, this article discussed, be Read More
