For some people with medically refractory epilepsy adjunct treatment with neurostimulation and ketogenic diet can be an option. Vagal nerve stimulation, VNS, consists of chronic intermittent electrical stimulation of the vagus nerve. VNS is effective and well tolerated in adolescents and adults. There is insufficient evidence on the efficacy of deep brain stimulation, DBS, and brain-responsive neurostimulation, RNS. Ketogenic diet is an established treatment in epilepsy with an increased number of indications, especially in neurometabolic diseases, where dietary therapy can completely eliminate epilepsy and improve cognitive and motor development...

In numerous diseases, abnormal expression of myocardial infarction‑associated transcript (MIAT) has been reported to be involved in cell proliferation, apoptosis and migration. However, whether this long non‑coding RNA MIAT has a regulatory effect on heart hypertrophy requires further investigation. To this end, the present study evaluated MIAT in hypertrophic cardiomyocytes in vitro and in vivo. Neonatal rat ventricular myocytes (NRVMs) were induced by isoproterenol (ISO) to create a cell hypertrophy model, and mice were intraperitoneally injected with ISO to establish an animal model...

Mutations leading to disorders within ion (mainly potassium and sodium) channels, have different degrees of expression in the brain and in the heart, which can cause simultaneous occurrence of disorders in both organs. This is manifested by the occurrence of epileptic seizures and cardiac electrical disturbances, further exacerbated by stimulation of autonomic structures within the central nervous system. In all patients with unclear paroxysmal disorders, and in those with unexplained sudden cardiac death, consideration should be given to the possibility of occurrence of genetically determined disorders in the ion channels...

Brain microbleeds are defined as small, circular hypointense changes in T2-sequensec of brain MRI, well demarcated from the surrounding tissue. They represent the phagocytized products of blood distribution extravasated from pathologically altered vessels. The echo-T2-dependent gradient (GRE) and magnetic susceptibility testing (SWI) sequences are usually used to visualize them. The pathogenesis of microbleeds very complex but angiopathy associated with arterial hypertension and cerebral amyloid angiopathy play a special role...

The functional disorders caused by central nervous system (CNS) diseases, such as ischemic stroke, are clinically incurable and current treatments have limited effects. Previous studies suggested that cell-based therapy using mesenchymal stem cells (MSCs) exerts therapeutic effects for ischemic stroke. In addition, the characteristics of MSCs may depend on their sources. Among the derived tissues of MSCs, we have focused on cranial bones originating from the neural crest. We previously demonstrated that the neurogenic potential of human cranial bone-derived MSCs (cMSCs) was higher than that of human iliac bone-derived MSCs...

Endothelial cells are critical in angiogenesis and maintain the homeostasis of the blood‑brain barrier (BBB). Platelets (PLTs) are essential in vascular biology, including angiogenesis. The present study aimed to investigate the effect of PLTs on the aging of endothelial cells. Human brain microvascular endothelial cells (HBMECs) and human astrocytes were co‑cultured to mimic the BBB. Transmission electron microscopy was used to observe the engulfment of PLTs. Confocal microscopy was used to observe the co‑localization of PLTs, girders of actin filament (girdin) and phosphorylated (p‑)girdin...

Parkinson's disease (PD) is a progressive neurodegenerative disease characterized by the loss of dopaminergic neurons in the substantia nigra (SN) and the reduction of dopamine levels in the striatum. Although details of the molecular mechanisms underlying dopaminergic neuronal death in PD remain unclear, neuroinflammation is also considered a potent mediator in the pathogenesis and progression of PD. In the present study, we present evidences that microglial NLRP3 inflammasome activation is critical for dopaminergic neuronal loss and the subsequent motor deficits in the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model of PD...

REVIEW
Xu-Feng Huang, Xueqin Song
Although antipsychotic drugs are mainly used for treating schizophrenia, they are widely used for treating various psychiatric diseases in adults, the elderly, adolescents and even children. Today, about 1.2% of the worldwide population suffers from psychosis and related disorders, which translates to about 7.5 million subjects potentially targeted by antipsychotic drugs. Neurites project from the cell body of neurons and connect neurons to each other to form neural networks. Deficits in neurite outgrowth and integrity are implicated in psychiatric diseases including schizophrenia...

Glial cell line-derived neurotrophic factor (GDNF) has demonstrated neurorestorative and neuroprotective effects in rodent and nonhuman primate models of Parkinson's disease. However, continuous intraputamenal infusion of GDNF (100 µg/day) resulted in multifocal cerebellar Purkinje cell loss in a 6-month toxicity study in rhesus monkeys. It was hypothesized that continuous leakage of GDNF into the cerebrospinal fluid compartment during the infusions led to down-regulation of GDNF receptors on Purkinje cells, and that subsequent acute withdrawal of GDNF then mediated the observed cerebellar lesions...

Hippocampal atrophy measures from magnetic resonance imaging (MRI) are powerful tools for monitoring Alzheimer's disease (AD) progression. In this paper, we introduce a longitudinal image analysis framework based on robust registration and simultaneous hippocampal segmentation and longitudinal marker classification of brain MRI of an arbitrary number of time points. The framework comprises two innovative parts: a longitudinal segmentation and a longitudinal classification step. The results show that both steps of the longitudinal pipeline improved the reliability and the accuracy of the discrimination between clinical groups...

Anti-NMDA receptor encephalitis is an acute form of brain inflammation that is potentially lethal but has a high probability for recovery with treatment. Although the clinical picture of anti-NMDAR encephalitis is usually recognizable due to its relatively well-known symptoms, the disorder can sometimes present itself in an unpredictable and atypical way. In this case report, we wish to present the influence of different delay times prior to the establishment of diagnosis. Thus, our first patient was diagnosed with anti-NMDAR encephalitis 4 years after the initial symptoms, the second one after 8 years, and the third one after 13 months...

Background: There is an ongoing debate whether primary lateral sclerosis (PLS) should be regarded as an independent disease entity separate from amyotrophic lateral sclerosis (ALS) or as a slowly progressive variant of ALS. Objective: The study was designed to investigate specific white matter alterations in diffusion tensor imaging (DTI) data from PLS patients by a hypothesis-guided tract-of-interest-based approach compared with 'classical' ALS patients and healthy controls, in order to identify microstructural changes according to the neuropathologically defined ALS affectation pattern in vivo...

Lesion of the dopaminergic neurons of the nigrostriatal system is a key feature of Parkinson's disease (PD). Alpha-synuclein is a protein that is a major component of Lewy bodies, histopathological hallmarks of PD, and is involved in regulation of dopamine (DA) neurotransmission. Previous studies of knockout mice have shown that inactivation of alpha-synuclein gene can lead to the reduction in number of DA neurons in the substantia nigra (SN). DA neurons of the SN are known to be the most affected in PD patients whereas DA neurons of neighboring ventral tegmental area (VTA) are much less susceptible to degeneration...

Although lung cancer has a high propensity for distant metastatic disease, penile metastases from primary lung neoplasms are considered particularly rare. A 71-year-old male presented to our hospital with a rapidly enlarging hard palpable penile mass. MR imaging demonstrated two penile masses centered in the left and right corpus cavernosa. Subsequent CT imaging revealed a spiculated pulmonary mass in the right upper lobe with PET/CT, MRI, and surgical exploration, demonstrating evidence of metastases to the left adrenal gland, right subscapularis muscle, brain, and small bowel...
