OBJECTIVE: To explore the characteristics of electroencephalogram (EEG) in patients with anti-N-methyl-d-aspartate receptor (anti-NMDAR) encephalitis. METHODS: Anti-NMDAR encephalitis patients admitted to the Department of Neurology between January 2012 and June 2016 were enrolled. All patients underwent electroencephalogram (EEG) at least once in the disease peak stage, and received tumor screening, symptomatic therapy, and immunotherapy. Patients received outcome evaluation every 6months after the immunotherapy, and modified Rankin scale (mRS) 0-2 was defined as favorable outcome...

Surgery precedes both radiotherapy and chemotherapy as the first-line therapy for glioma. However, despite multimodal treatment, most glioma patients die from local recurrence in the resection margin. Glioma surgery is inherently lesional, and the response of brain tissue to surgery includes hemostasis, angiogenesis, reactive gliosis and inflammation. Unfortunately, these processes are also associated with tumorigenic side-effects. An increasing amount of evidence indicates that the response to a surgery-related brain injury is hijacked by residual glioma cells and participates in the local regeneration of tumor tissues at the resection margin...

Dystonia, which causes intermittent or sustained abnormal postures and movements, can present in a focal or a generalized manner. In the limbs, focal dystonia can occur in either the upper or lower limbs and may be task-specific causing abnormal motor performance for only a specific task, such as in writer's cramp, runner's dystonia, or musician's dystonia. Focal limb dystonia can be non-task-specific and may, in some circumstances, be associated with parkinsonian disorders. The true prevalence of focal limb dystonia is not known and is likely currently underestimated, leaving a knowledge gap and an opportunity for future research...

IgG4-related sclerosing disease of the larynx (IgG4-SD) is a recently described immunodependent systemic pathology characterized by diffusive or focal inflammatory infiltration of the affected organs and tissues by plasma cells expressing IgG4; it is accompanied by the subsequent development of obliterative phlebitis and fibrosclerosis associated with the increase of the serum IgG4 level. According to the recently published materials, the disease can also develop in the respiratory system. The present article describes the first documented case of IgG4-related sclerosing disease with the isolated lesion of the larynx...

New strategies must be developed to resolve the problems of stroke treatment. In recent years, stem cell-based therapy after stroke has come into the public and academic lens. Previously we have shown that uncoupling neuronal nitric oxide synthase (nNOS) from the postsynaptic density protein-95 (PSD-95) by ZL006, a small molecular compound, can ameliorate ischemic damage and promote neuronal differentiation of endogenous neural stem cells (NSCs) in focal cerebral ischemic male rats. In this study, we transplanted exogenous NSCs into the ipsilateral hemisphere of male rats in combination with ZL006 treatment after ischemic stroke...

Aquaporins (AQP) are the membrane proteins involved in the transport of water and some neutral solutes. Thirteen types of AQP are identified in various human tissues. The expression of AQP's has been studied in various tumors among one is oral cancer. These molecules are involved in cell proliferation, migration, and metastasis. AQP target inhibitors act directly or indirectly through focal adhesion kinase-mitogen-activated protein kinase signaling pathway and shown promising results along with anti-cancer drugs...

BACKGROUND: Seizures are a common early presentation in infants with tuberous sclerosis complex (TSC) and can be preceded by electrographic changes on electroencephalography (EEG) before clinical seizure onset. A limited number of studies have addressed the initial EEG findings in TSC and the outcome of early treatment with antiepileptic medication prior to clinical seizure onset. METHODS: We describe two infants with tuberous sclerosis complex whose surveillance EEG showed focal seizures that were not previously recognized by caregivers...

Autoimmune hepatitis (AIH) may have an atypical serum alkaline phosphatase elevation, antimitochondrial antibodies, histologic features of bile duct injury/loss, or cholangiographic findings of focal biliary strictures and dilations. These manifestations characterize the overlap syndromes. Patients can be classified as having AIH with features of primary biliary cholangitis, primary sclerosing cholangitis, or a cholestatic syndrome. The gold standard of diagnosis is clinical judgment. Histologic evaluation is a major diagnostic component...

OBJECTIVE: Laser interstitial thermal therapy (LITT) has become increasingly popular for targeting epileptic foci in a minimally invasive fashion. Despite its use in more than a thousand patients, the chronic effects of photo-thermal injury on brain physiology remain poorly understood. METHODS: We prospectively followed the clinical and radiographic courses of a cohort undergoing laser ablation for focal epilepsy. Only patients with non-enhancing lesions and those who had a delayed post-operative MRI with gadolinium administration approximately 6 months after the ablation were considered...

Cerebral cavernous malformations (CCMs) are common vascular anomalies that develop in the central nervous system and, more rarely, the retina. The lesions can cause headache, seizures, focal neurological deficits, and hemorrhagic stroke. Symptomatic lesions are treated according to their presentation; however, targeted pharmacological therapies that improve the outcome of CCM disease are currently lacking. We performed a high-throughput screen to identify Food and Drug Administration-approved drugs or other bioactive compounds that could effectively suppress hyperproliferation of mouse brain primary astrocytes deficient for CCM3...

The identification of new targets for systemic therapy of hepatocellular carcinoma (HCC) is an urgent medical need. Recently, we showed that hNatB catalyzes the N-α-terminal acetylation of 15% of the human proteome and that this action is necessary for proper actin cytoskeleton structure and function. In tumors, cytoskeletal changes influence motility, invasion, survival, cell growth and tumor progression, making the cytoskeleton a very attractive antitumor target. Here, we show that hNatB subunits are upregulated in in over 59% HCC tumors compared to non-tumor tissue and that this upregulation is associated with microscopic vascular invasion...

A focal neurological deficit with sudden onset or rapid progression is an alarming symptom indicating a neurological disorder with often urgent need for treatment. Particularly in the emergency room, where time and resources are limited, it is necessary to rapidly assign such a focal neurological deficit to a certain syndrome and to define a suspected diagnosis in order to execute the correct diagnostics and emergency therapy. In this article, we highlight frequent and typical neurological disorders presenting in the emergency room and their corresponding focal neurological deficits...

Individuals with pharmacoresistant epilepsy remain a large and under-treated patient population. Continued technologic advancements in implantable neurostimulators have spurred considerable research efforts directed towards the development of novel antiepileptic stimulation therapies. However, the lack of adequate preclinical experimental platforms has precluded a detailed understanding of the differential effects of stimulation parameters on neuronal activity within seizure networks. In order to chronically monitor seizures and the effects of stimulation in a freely-behaving non-human primate with idiopathic epilepsy, we employed a novel simultaneous video-intracranial EEG recording platform using a state-of-the-art sensing-enabled, rechargeable clinical neurostimulator with real-time seizure detection and wireless data streaming capabilities...

Ischemic brain stroke is caused by blood flow interruption, leading to focal ischemia, neuron death, and motor, sensory, and/or cognitive dysfunctions. Angiogenesis, neovascularization from existing blood vessel, is essential for tissue growth and repair. Proangiogenic therapy for stroke is promising for preventing excess neuron death and improving functional recovery. Vascular endothelial growth factor (VEGF) is a critical factor for angiogenesis by promoting the proliferation, the survival, and the migration of endothelial cells...
