Arisaema heterophyllum Blume is one of the three medicinal plants known as traditional Chinese medicine Rhizoma Arisaematis (RA). RA has been popularly used to treat patients with convulsions, inflammation, and cancer for a long time. However, the underlying mechanisms for RA effects are still unclear. The present study was designed to determine the cytotoxicity of agglutinin isolated from Arisema heterophyllum Blume (AHA) and explore the possible mechanisms in human non-small-cell lung cancer A549 cells. AHA with purity up to 95% was isolated and purified from Arisaema heterophyllum Blume using hydrophobic interaction chromatography...

Aeollanthus suaveolens species popularly known as catinga de mulata belongs to the Lamiaceae family. In the Amazon region, it is used in folk medicine for the treatment of gastritis, convulsions of epileptic origin, stomach pain and diarrhea in the form of tea and juice. Essential oils have analgesic, anti-inflammatory, and antimicrobial activity. This study evaluated the chemical composition of the A. suaveolens essential oil, and its cytotoxic, antimicrobial and antioxidant activity on Artemia salina Leach...

Optimization of the previously reported benzothiazine analogue A led to the identification of compound 1, which showed anti-convulsant activity in two golden standard animal models of seizure, the MES and scPTZ models. Structure-activity relationship investigation of compound 1 revealed compounds 2, 6 and 19 as attractive anti-epileptic drug (AED) candidates with potent anticonvulsant effect in both the MES and scPTZ models. As these compounds are structurally different from existing AEDs, determination of their mechanism of actions could provide clues to understanding current therapy-resistant seizures...

A male 46 year-old patient was admitted to the Emergency Intensive Care Unit of Qinghai Provincial People's Hospital (Xining, China) in December 2008 with complaints of a headache and fever that had lasted for three days. In addition, the patient had experienced two general convulsions accompanied with consciousness disorders for 7 h. Although the patient's clinical manifestations, laboratory tests and cerebrospinal fluid examinations were consistent with numerous features associated with acute encephalitis, the patient's clinical course was different to that of acute encephalitis, and the prognosis was poor...

PURPOSE: Valproate is an effective wide-spectrum anti-epileptic drug that is also known to be teratogenic. Its administration in epileptic women remains controversial. This report aims to draw more attention to valproate adjustment before and during pregnancy. METHODS: We collected medical records of pregnant women with epilepsy at West China Hospital in Chengdu, China who developed status epilepticus during pregnancy after valproate withdrawal or reduction in dose from January 2013 to July 2015...

Vertigo and dizziness are with an annual incidence of more than 10% and a lifetime prevalence of more than 30% among the most frequent symptoms. The keys to the diagnosis are the patient history and the bedside examination: a) for the patient history the time course, type and triggers of symptoms and accompanying symptoms, b) for the clinical examination of the vestibular system the head-impulse test (HIT), the examination for a spontaneous nystagmus, a displacement of subjective visual vertical, a positional nystagmus and the Romberg test, and c) for the differentiation between an acute peripheral and central vestibular lesion the skew deviation, central fixation nystagmus, gaze-evoked nystagmus, saccadic smooth pursuit and a normal HIT...

MEDI-575, an immunoglobulin G2κ monoclonal antibody, selectively binds to platelet-derived growth factor-α receptor (PDGFR-α) with high specificity. This multicenter, single-arm, open-label, phase II study evaluated the efficacy and safety of MEDI-575 in patients with recurrent glioblastoma. Adults with first recurrence of glioblastoma following surgery, temozolomide, and radiation received MEDI-575 25 mg/kg intravenously over 60 min every 21 days until disease progression or unacceptable toxicity. Six-month progression-free survival rate (PFS-6) was the primary end point; secondary measures included response rate, overall survival (OS), and safety/tolerability...

SCN8A encephalopathy is a severe, early-onset epilepsy disorder resulting from de novo gain-of-function mutations in the voltage-gated sodium channel Nav1.6. To identify the effects of this disorder on mRNA expression, RNA-seq was performed on brain tissue from a knock-in mouse expressing the patient mutation p.Asn1768Asp (N1768D). RNA was isolated from forebrain, cerebellum, and brainstem both before and after seizure onset, and from age-matched wildtype littermates. Altered transcript profiles were observed only in forebrain and only after seizures...

STUDY DESIGN: Relevant publications in English and Italian were identified through search of MEDLINE and the Cochrane Database of Systematic Reviews from May 2012 to November 2015. RESULTS: Previous recommendations are substantially reaffirmed. Antipyretics should be administered with the purpose to control the child's discomfort...

INTRODUCTION: In myotonia congenita, loss of ClC-1 Cl(-) -channel function results in skeletal muscle hyperexcitability and myotonia. Anti-myotonic treatment has typically targeted the voltage gated sodium channel in skeletal muscle (Nav1.4). This study explored whether 3 sodium channel modulating anti-epileptics can reduce myotonia in isolated rat and human muscle. METHODS: Dissected muscles were rendered myotonic by ClC-1 channel inhibition. The ability of the drugs to suppress myotonia was then assessed from sub-clinical to maximal clinical concentrations...

Gardeniae Fructus (GF, Zhi Zi in China), a fruit of Gardenia jasminoides Ellis, has been used in traditional medicine to reduce inflammation and headache and to treat hepatic disorders, hypertension, and icterus. In recent studies, extract of raw or stir-baked GF was shown to have pharmacological activities for viral infection, thrombosis, hyperlipidemia, convulsion, inflammation, oxidative stress, and others. In addition, baked GF extract suppressed the proteolytic activities and altered the cellular morphology of tumor cells...

Piroxicam is a benzothiazine compound with anti-inflammatory, antipyretic, and analgesic properties. Because of the very high efficacy of piroxicam and its increasing use in the treatment of carcinomas in dogs and cats, there is a need for acute toxicity study of piroxicam in monogastric animals and its potential for causing secondary poisoning in puppies. Piroxicam manufactured by Shanxi Federal Pharmaceutical Co, Ltd. was used for this study. Revised up-and-down procedure was used for the estimation of median lethal dose in mouse (259...

According to the seventh report of Joint National Committee (JNC 7), hypertensive emergency (HE), a kind of hypertensive crisis, is defined as a sudden and abrupt elevation in blood pressure so as to cause acute target organ dysfunctions, including central nervous system, cardiovascular system or kidneys. Patients with HE require immediate reduction in markedly elevated blood pressure. Currently, there are no international guidelines for children HE, so the JNC definition is commonly used. Hypertensive emergency in children is rare but a life-threatening emergency...

Inflammation plays a pivotal role in status epilepticus (SE). Thymoquinone (TQ) is a bioactive monomer extracted from black seed (Nigella sativa) oil, which has anti-inflammatory properties in the context of various diseases. This study explored the protective effects of TQ in SE and used a lithium-pilocarpine model of SE to investigate the underlying mechanism, which was related to inflammation mediated by the NF-κB signaling pathway. In the present study, latency to SE increased in the TQ-pretreated group compared with the SE group, and the incidence of SE was significantly reduced...

Since 24 states and the District of Columbia have legalized marijuana in some form, suppliers of legal marijuana have developed Cannabis sativa products for use in electronic cigarettes (e-cigarettes). Personal battery powered vaporizers, or e-cigarettes, were developed to deliver a nicotine vapor such that smokers could simulate smoking tobacco without the inherent pathology of inhaled tobacco smoke. The liquid formulations used in these devices are comprised of an active ingredient such as nicotine mixed with vegetable glycerin (VG) and/or propylene glycol (PG) and flavorings...
