Distinctive Olfactory Pattern in Parkinson's Disease and Non-Neurodegenerative Causes of Hyposmia.

Distinctive Olfactory Pattern in Parkinson's Disease and Non-Neurodegenerative Causes of Hyposmia. Neurodegener Dis. 2018 Jun 25;:1-7 Authors: Crespo Cuevas AM, Ispierto L, Vilas D, Planas A, Planas A, Isern I, Sanchez J, De Haro J, Alvarez R Abstract BACKGROUND: Olfactory dysfunction is common in Parkinson's disease (PD). The characteristics of the hyposmia in PD have not been well defined. OBJECTIVE: To characterize the pattern of the olfactory deficit in PD and in other non-neurodegenerative aetiologies of hyposmia. METHODS: We evaluated 36 PD patients, 20 patients with hyposmia secondary to acute respiratory infection (ARI), and 19 patients with hyposmia secondary to traumatic brain injury (TBI). For comparison purposes, we included a group of 15 controls age and sex matched with PD patients. PD patients were classified based on disease duration and severity in de novo PD, and PD with and without chronic levodopa-related complications. The Barcelona Smell Identification Test was applied to all participants. RESULTS: For the first cranial nerve odours, PD patients scored lower than controls on smell detection (85.28 vs. 97.67%, p = 0.006), definition (79.58 vs. 93.33%, p = 0.007), recognition (63.33 vs. 81%, p = 0.020), and forced choice (58.06 vs. 82%, p

Abstract A gene co-expression network (CEN) is of biological interest, since co-expressed genes share common functions and biological processes or pathways. Finding relationships among modules can reveal inter-modular preservation, and similarity in transcriptome, functional, and biological behaviors among modules of the same or two different datasets. There is no method which explores the one-to-one relationships and one-to-many relationships among modules extracted from control and disease samples based on both topological and semantic similarity using both microarray and RNA seq data. In this work, we propose a...

Monosynaptic rabies tracing can be used to map inputs to stem cell ‐derived neurons grafted to models of neurodegenerative disease and injury. These studies indicate that graft neurons receive anatomically‐appropriate inputs, but it remains to be determined whether those inputs are necessary for functional recovery. Next‐generation rabies tracing is poised to address this outstanding question, which may aid ongoing translational efforts. ABSTRACTFetal neural progenitor grafts have been evaluated in preclinical animal models of spinal cord injury and Parkinson's disease for decades, but the initial reliance on primary...

This study describes the novel strategy for the robust generation of homogeneous MOs using specific combination of dual SMAD inhibitors andin vitro WNT gradient. DAC3.0 MOs generated by our optimized protocol within vivo‐like cellular composition are as structurally and functionally mature as the developing midbrain. DAC3.0 MOs with functional glial cells including astrocytes facilitate MPTP‐basedin vitro disease modeling of PD, suggesting its potential usefulness for an advanced patient ‐specific platform forin vitro disease modeling as well as for drug screening for PD. AbstractRecent studies have demonstrated the ...

ConclusionAll the data of this study revealed that the decreased serum miR ‐150 serves as a potential diagnostic biomarker. The methods to increase miR‐150 expression may have a beneficial effect in PD via suppressing the neuroinflammation by targeting AKT3.

Helicobacter pylori is one of the most prevalent infection worldwide. It affects individuals of different age groups. Aging ‐associated risk factors should be considered. Future studies, related to aging andH. pylori infection with extragastric disease can help to provide vivid evidences. AbstractHelicobacter pylori is one of the most prevalent infection worldwide. It affects individuals of different age groups. Elderly people tend to resist eradication treatment and worsening of infection can lead to several gastric and non ‐gastric pathologies. Aging‐associated cellular and molecular alteration can increase the ris...
