Blood α‐Synuclein Separates Parkinson's Disease from Dementia with Lewy Bodies

open access: yesAnnals of Neurology, EarlyView.
Objective Aggregation of misfolded α‐synuclein (aSyn) within the brain is the pathologic hallmark of Lewy body diseases (LBDs), including Parkinson's disease (PD), and dementia with Lewy bodies (DLB) disease. Although evidence exists for aSyn “strains,” conformations with distinct biological properties, biomarkers for PD versus DLB are lacking.

Connectivity-based functional analysis of dopamine release in the striatum using diffusion-weighted MRI and positron emission tomography.

open access: yesCerebral Cortex, 2014
The striatum acts in conjunction with the cortex to control and execute functions that are impaired by abnormal dopamine neurotransmission in disorders such as Parkinson's and schizophrenia.

Ethnomedicinal Uses, Phytochemistry, Pharmacological Activities, and Toxicology of the Subfamily Gomphrenoideae (Amaranthaceae): A Comprehensive Review

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT The subfamily Gomphrenoideae is composed of about 480 accepted species, many of which have been historically used as medicinal plants, reason why they have been studied in terms of chemical profile, biological activity, and safety. This review consolidates the advances in research on this subfamily over the past 47 years, emphasizing its ...

Context-Induced Reinstatement of Methamphetamine Seeking Is Associated with Unique Molecular Alterations in Fos-Expressing Dorsolateral Striatum Neurons

open access: yesJournal of Neuroscience, 2015
Context-induced reinstatement of drug seeking is a well established animal model for assessing the neural mechanisms underlying context-induced drug relapse, a major factor in human drug addiction. Neural activity in striatum has previously been shown to

Probing the Inhibitory Potential of Halogenated Symmetrical Formamidine Against MAO‐A and MAO‐B: Structural Elucidation, Molecular Dynamic Simulation and DFT Computational Studies

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT A halogenated symmetrical formamidine, N,N′‐bis(3‐chloro‐4‐fluorophenyl)formamidine (FCF) was synthesized by the condensation reaction between triethyl orthoformate and 3‐chloro‐4‐fluoroaniline in 1:2 ratio. The compound FCF was characterized by FT‐IR, mass, NMR (1H and 13C) spectroscopic techniques and the purity was confirmed by elemental ...

A Major External Source of Cholinergic Innervation of the Striatum and Nucleus Accumbens Originates in the Brainstem

open access: yesJournal of Neuroscience, 2014
Cholinergic transmission in the striatal complex is critical for the modulation of the activity of local microcircuits and dopamine release. Release of acetylcholine has been considered to originate exclusively from a subtype of striatal interneuron that

Manganese Neurotoxicity and Familial Disorders of Manganese Transport

open access: yesAnnals of the Child Neurology Society, EarlyView.
ABSTRACT Manganese is the 12th most common element in the Earth's crust and is an essential industrial component. Biologically, this metal plays an important role as a constituent of numerous enzymes. While manganese is required for normal biochemical and physiological processes, manganese excess can lead to significant toxicity, particularly to the ...

Biofilm production by multiresistant Corynebacterium striatum associated with nosocomial outbreak

open access: yesMemórias do Instituto Oswaldo Cruz, 2015
Corynebacterium striatum is a potentially pathogenic microorganism that causes nosocomial outbreaks. However, little is known about its virulence factors that may contribute to healthcare-associated infections (HAIs).
