Purpose/Aim: Antenatal corticosteroid therapy (ACS) has dramatically increased survival rates among extremely low birthweight (ELBW) infants. However, the long term effects of ACS on autonomic nervous system function have not been explored. Using the world's oldest longitudinally followed cohort of ELBW infants we compared respiratory sinus arrhythmia (RSA) among ELBW survivors whose mothers received ACS (ELBW-S), those who did not (ELBW-NS), and normal birth weight (NBW) controls in their 20s and 30s. METHODS: Resting electrogardiogram (ECG) was recorded from ELBW-S (n=28), ELBW-NS (n=36), and matched NBW controls (n=79) at 22-26 years and 29-36 years...

Background At present, there are no meaningful and sophisticated computer games that simultaneously allow the treatment of movement disorders such as Parkinson's syndrome. In particular, there are no systems to consider the severity of the disease and the physical skills of the patient. Methods A computer game using the Microsoft Kinect as markerless sensor for the 3D recognition of the patient's movement was developed to support the rehabilitation. The scenario of a basketball game was created after determining that the movement like throwing a ball and the correct posture of the body are important...

Primary culture is an effective experimental model to study molecular mechanisms that drive axonal regeneration after central nervous system injury. Nevertheless, the culture of spinal cord (SC) cells remains poorly characterized. Here, we have analysed the cell composition of a primary SC culture during its maturation. It was found that β3-tubulin (general neuronal marker) and nestin (a marker of neuronal stem cells) were both expressed at day 2 of culture in vitro. Surprisingly (given the use of differentiation-supporting culture medium), the number of nestin+ cells has significantly increased during the first week of cultivation...

Motor imagery (MI) is the mental representation of a movement without engaging its actual execution. MI shares neuroanatomical correlates with brain motor networks. Neurologic disorders affecting motor skills, such as stroke, have been related to impairments in MI. A descriptive review was conducted to explore the effects of stroke on MI ability and its background mechanisms. We searched on PubMed and Web of Science databases and screening references of included studies and review articles for additional citations...

AIM: Autophagy was activated after cerebral ischemia reperfusion (I/R) injury. However, the molecular mechanisms underlying regulation of autophagy in cerebral I/R injury were not completely understood. Studies reported that Forked-box class O (FoxO) transcription factors involved in autophagy and might be the regulator of autophagy in multiple cells. In this study, we investigated the effects of FoxO3 on regulating autophagy after cerebral I/R injury. MATERIALS AND METHODS: Rats were subjected to MCAO for 2 h and reperfusion for different times, western blot was used to examine the expression of p-FoxO3, FoxO3 and the autophagic marker LC3 and Beclin-1 in penumbral region...

The main pathological change of Parkinson's disease (PD) is progressive degeneration and necrosis of dopaminergic neurons in the midbrain, forming a Lewy body in many of the remaining neurons. Studies have found that in transgenic Drosophila, mutations in the PTEN-inducible kinase 1 (PINK1) gene may cause indirect flight muscle defects in Drosophila, and mitochondrial structural dysfunction as well. In this study, Wnt4 gene overexpression and knockdown were performed in PINK1 mutant PD transgenic Drosophila, and the protective effect of Wnt4 gene on PD transgenic Drosophila and its possible mechanism were explored...

Oligodendrogliomas are a rare type of primary brain tumor. They are genetically defined as diffuse gliomas carrying mutation in isocitrate dehydrogenase type 1 (IDH1) or type 2 (IDH2) and codeletion of chromosomes 1p and 19q. The WHO grading system distinguishes two histopathologic grades of ODs: grade II (low-grade) and grade III (anaplastic oligodendroglioma or AO). These tumors rarely metastasize outside of central nervous system with only few cases reported in the literature. Here we present a case of an AO, which metastasized to the bone marrow and other sites within a year of diagnosis despite aggressive treatment measures...

This study was aimed at examining the epileptiform activity of the 5-HT2 serotonin receptor agonist and antagonist, and 5-hydroxytryptophan (5-HTP) in penicillin-induced epilepsy in albino Wistar rats. For this purpose, 90 albino male Wistar rats were used in this study. Epileptiform activity was induced by an injection of penicillin, an agonist of GABAA receptor, (500 IU, ic) into the somatomotor cortex. Thirty minutes after the injection of penicillin, 2,5-dimethoxy-4-iodoamphetamine (DOI, an agonist of 5-HT2 receptor) (0...

OBJECTIVE: Although individual differences in personality are known to influence quality of life in individuals with schizophrenia, relatively few studies have attempted to identify putative links underlying this relation. METHODS: Here, we examined associations among temperamental shyness, hormones (ie baseline salivary cortisol and testosterone), and quality of life (QoL) measured in 42 stable outpatient adults with schizophrenia. RESULTS: We found that baseline cortisol, but not testosterone, moderated the relation between shyness and QoL (ß = 1...

INTRODUCTION: Epilepsy occurs in 35-70% of patients with gliomas; glutamate plays a central role via AMPA-receptor activation, which is involved both in seizure activity and tumor growth. We conducted a retrospective study on brain tumour-related epilepsy patients (BTRE) treated with perampanel in add-on (PER) for 12 months, to evaluate efficacy and tollerability, according to real-life clinical practice. MATERIALS AND METHODS: Medical records of eleven patients (9 males, mean age 54 years) with glioma and epilepsy treated with PER in add-on, for inadequate seizure control or adverse events (AEs) from previous antiepileptic drugs (AEDs) therapy, were reviewed...
