BACKGROUND: Recorded history shows that malaria has plagued mankind for centuries, if not millennia, with the disease infecting and affecting several body tissues, organs and systems; including the central nervous system. Cerebral malaria is a severe form of malaria that may be associated with acute and chronic general behavioural, neurological or neuropsychiatric manifestations. The observation that the use of certain antimalaria drugs may also be associated with behavioural, neurochemical and structural brain changes complicates the picture, as both the infection and its treatment may cause significant changes in brain structure/function and behaviour...

BACKGROUND: Gamma-decanolactone (GD) is a monoterpene compound that presents anticonvulsant effect in acute and chronic models of epilepsy and it acts as a noncompetitive glutamate antagonist. OBJECTIVE: This study evaluated the anticonvulsant profile and the possible mechanism of action of GD in seizures induced by isoniazid (INH; 250 mg/kg), picrotoxin (PCT; 5 mg/kg) and 4-aminopyridine (4-AP; 13 mg/kg) in male mice. METHOD: Thirty minutes before the convulsants administration, animals received a single administration of saline, GD (100 or 300 mg/kg) or the positive control diazepam (DZP; 2 mg/kg)...

Several recent developments in melatonin research deserve attention and divulgation. The role of melatonin in the brain has been extended to its synthesis in the cerebellum as a response to inflammation, findings that exceed the earlier demonstration of aralkylamine N-acetyltransferase expression. The release of melatonin via the pineal recess into the third ventricle appears to be more important than previously believed and has been discussed as a strong direct signal to the suprachiasmatic nucleus. The mitochondrial role of melatonin has been substantially extended by the demonstration of the melatonin receptor MT1 in this organelle and evidence for melatonin synthesis in mammalian mitochondria, in addition to the previously shown uptake into these organelles...

BACKGROUND: Glycogen synthase kinase-3β plays a significant role in the regulation of various pathological pathways relating to central nervous system (CNS). Dysregulation of Glycogen synthase kinase 3 (GSK-3) activity gives a rise to numerous neuroinflammation and neurodegenerative related disorders that affect the whole central nervous system. OBJECTIVE: By the sequential application of in-silico tools, efforts have been attempted to design the novel GSK-3β inhibitors...

Chalcone has been identified as a promising lead for the design of monoamine oxidase (MAO) inhibitors. This study attempted to discover potent and selective chalcone-derived MAO inhibitors by synthesising a series consisting of various cyclic chalcone derivatives. The cyclic chalcones were selected based on the possibility that their restricted structures would confer a higher degree of MAO isoform selectivity, and included the following chemical classes: 1-indanone, 1-tetralone, 1-benzosuberone, chromone, thiochromone, 4-chromanone and 4-thiochromanone...

The efficacy of L-dopa in the treatment of Parkinson's disease depends on its metabolic conversion to dopamine in the brain, however extensive peripheral metabolism of L-dopa diminishes its availability for uptake into the brain. L-Dopa is extensively decarboxylated in the gastrointestinal tract and peripheral tissues by aromatic L-amino acid decarboxylase (AADC), and AADC inhibitors are thus frequently combined with L-dopa therapy. When AADC is inhibited, 3-O-methylation catalysed by catechol-O-methyltransferase (COMT) becomes a dominant metabolic pathway for L-dopa, and COMT inhibitors may thus also be used as adjuncts to L-dopa in Parkinson's disease...

INTRODUCTION: Parkinson's disease is affecting millions of people worldwide. The prevalence of Parkinson's disease is 0.3% globally, rising to 1% in more than 60 years of age and 4% in more than 80 years of age and the figures are thought to be doubled by 2030. Thus, there is a great need to identify novel therapeutic strategies or candidate drug molecule which can rescue neuronal degeneration. β-asarone has potential to act as a neuroprotective agent but regarding its role in Parkinson disease, very few reports are available...

BACKGROUND: The transport of CNS acting drugs across blood-brain barrier (BBB) is complex and guided by the molecular weight, pH, physicochemical and pathological state of the BBB among others. METHODS: In view of this, literatures were assessed for possible conversion of Non-CNS to CNS acting drugs, whose ability to penetrate CNS can be improved using polymers for biomedical applications. RESULTS: The findings have shown that compounds with pyridine, pyrrole, carboxamide, pyridone among others can be converted to CNS acting drugs that can be loaded in specialized carrier polymers for transportation across BBB...

BACKGROUND: Adequate function of the nervous system depends on the balance of glianeuron complex interactions. Astrocytes, in particular, are key elements in this process due to the significant participation of these cells in essential properties of the nervous system such as neuroinflammation, regulation of neurotransmitters, release of gliotransmitters and control of synaptic plasticity, among others. Astrocytes express the receptor for advanced glycation end products (RAGE) which is very important in the recognition of endogenous molecules released in the context of infection, physiological stress or chronic inflammation...

BACKGROUND AND OBJECTIVE: Bacterial meningitis is a serious disease with high rate of mortality and morbidity in children. Invasion of pathogens causes brain and meningeal inflammation, which leads to the release of biomarkers into cerebrospinal fluid (CSF). Identification of these biomarkers can help the physicians to differentiate between bacterial and aseptic meningitis. In the current study, some of these biomarkers such as Procalcitonin, C reactive protein (CRP), and Ferritin, were compared in cerebrospinal fluid (CSF) of patients with bacterial and aseptic meningitis...

INTRODUCTION: Neuromyelitis optica (NMO) and Multiple Sclerosis (MS) have been reported in different populations. NMO is more frequent in non-Caucasians, and clinical phenotype differences between populations are likely influenced by genetic susceptibility. In Brazil, it has been reported that NMO patients have a mainly European ancestry background. Like other autoimmune diseases, NMO has a multifactorial origin (i.e., genetics, environmental and infectious factors). Regarding the genetics of NMO, epidemiological findings suggest that a polygenic background has an important role in the development of this type of disease...

INTRODUCTION: Multiple Sclerosis (MS) is a chronic, inflammatory, neurodegenerative demyelinating disease of the central nervous system (CNS). Unfortunately, MS causes important disability in young adults and its prevalence is increasing. While the etiology of MS etiology is not completely understood, it seems to be a multifactorial entity that is influenced by both genetic and epigenetic modifications. Epigenetic mechanisms add or remove different chemical groups for the activation or inhibition of gene expression to block the production of proinflammatory proteins...

BACKGROUND: Chronic demyelinating diseases of the central nervous system (CNS) are autoimmune conditions that, although rarely fatal, may lead to severe disability. Among these diseases, Multiple Sclerosis (MS) and neuromyelitis optica (NMO) are particularly important and subject of worldwide research. MS and NMO are chronic types of CNS disease, with recurrent episodes of demyelination. For many years, these two conditions were considered to be only one, but lately it is known that they have different epidemiological, physiopathological and prognostic characteristics...

BACKGROUND: A complete neurological exam contributes in establishing spinal cord injury severity and its extent by identifying the damage to the sensory and motor pathways involved in order to address a more case-specific and precise pharmacological therapy. However, assessment of neurologic function in spinal cord injury models is usually reported by using sensory or motor tests independently. METHODS: A reliable integral method is needed to precisely evaluate location and severity of the injury at baseline and, in further assessments, to establish the degree of spontaneous recovery...

Epilepsy is one of the most significant chronic neurological disorders with high occurrence worldwide. Many epileptic patients are not completely treated with currently available marketed drugs as well as so many drugs have shown unfavorable side effect and drug interaction. Therefore, there are continuing interests to find new anticonvulsant drugs. Recently, there has been wide interest in compounds containing the isatin moiety with diverse biological effects. In view of the previous continuation of an ongoing program aiming at finding new structure leads to potential anticonvulsant activities, we are trying to compile recent efforts which have been made in the design and development of isatin derived anticonvulsant agents...
