Segarra, Isabel Prieto, Francisco Vives, Marc de Gasparo, Raquel Duran, Juan de Dios Luna, Manuel Ramírez-SánchezAbstractAminopeptidase A is responsible for the hydrolysis of angiotensin II and cholecystokinin. By measuring its activity we obtain a reflection of the functional status of its endogenous substrates. Dopamine coexists with these neuropeptides in striatum and prefrontal cortex. If the content of any of them is altered, the others and the functions they are involved in w...

However, the genetic spectrum of ATP13A2-associated disorders was expanded in the last years, because it has been found to underlay variants of neuronal ...

Authors: Seritan AL, Rienas C, Duong T, Delucchi K, Ostrem JL Abstract OBJECTIVE: Parkinson's disease (PD) is a quintessential neuropsychiatric condition in which anxiety and depressive symptoms are common and may precede motor manifestations. The authors explored the ages at onset of anxiety and depressive disorders among patients with PD evaluated by psychiatrists at a deep brain stimulation center. METHODS: Psychiatric diagnoses and ages at onset were collected via clinical interviews. The ages at PD diagnosis were ascertained by chart review. Onset ages for anxiety and depressive disorders (overall and for ...

The U.S. diagnostic market celebrated three regulatory firsts last week.  1. FDA Authorizes Marketing of First Zika Test Until now, tests for detecting Zika virus immunoglobulin (IgM) antibodies in blood were only authorized for emergency use under FDA's Emergency Use Authorization (EUA) authority. On Thursday, the agency said it has authorized marketing of the ZIKV Detect 2.0 IgM Capture ELISA under the agency's traditional premarket authority. The test is manufactured by InBios International. “At the onset of the Zika virus outbreak, when little was known about the disease or how...

ConclusionWe used gold nanoparticles loaded exosomes for in-vivo neuroimaging and present specific migration and homing to various brain pathologies including stroke, Parkinson's, Alzheimer's, Autism and healthy brains as a control. By this method, we visualized the migration and homing abilities of exosomes in long-term follow-up ad report that in pathological areas they home for more than 96 hours while in healthy brains they are being evacuated within 24 hours. Furthermore, we show that MSC-exo uses chemotaxis signaling to target the inflammatory areas in the brain.

This article covers the pharmacological treatment of depression in PD; this involves standard antidepressant treatment such as selective serotonin reuptake inhibitors, tricyclic antidepressants, serotonin and norepinephrine reuptake inhibitors, and monoamine oxidase inhibitors. As with depression not associated with PD, most treatment is partially successful. Non-pharmacological approaches are also touched upon. Expert opinion: Most antidepressant therapy shows partial efficacy in patients with PD. However, there is a need for better study design as well as more comparative studies for the treatment of depression in PD. Bi...

Publication date: Available online 23 May 2019Source: Journal of Molecular Graphics and ModellingAuthor(s): Ghada Omar Tuffaha, Mamon M. Hatmal, Mutasem O. TahaAbstractThe kinase c-Jun N-terminal Kinase 3 (JNK3) plays an important role in neurodegenerative diseases. JNK3 inhibitors have shown promising results in treating Alzheimer's and Parkinson's diseases. This prompted us to model this interesting target via three established structure-based computational workflows; namely, docking-based Comparative Intermolecular Contacts Analysis (db-CICA), pharmacophore modeling via molecular-dynamics based Ligand-Receptor Contact A...

ConclusionThese findings represent evidence of the lack of vRNA persistence in the reproductive tract, in ZIKV exposed and/or recently infected reproductive age women and could help simplify current guidelines.
