Investigation of the neuroprotective effects of thymoquinone on rat spinal cord exposed to 900 MHz electromagnetic field
Publication date: Available online 19 June 2019Source: Journal of Chemical NeuroanatomyAuthor(s): Ahmad yahyazadeh, Berrin Zuhal AltunkaynakAbstractExposure to electromagnetic field in long-term use of cell phones has increased concerns about serious health problems. Our aim was to survey the possible effects of electromagnetic field radiation (60 min/day for 28 days) on the spinal cords of 12 weeks old rats. Further, we investigated whether the administration of thymoquinone (10 mg/kg/day) would protect the spinal cord tissue against the adverse effects of electromagnetic field or not.

Method for Labeling and Reconstruction of Single Neurons Using Sindbis Virus Vectors
We describe in detail a protocol for single-neuron labeling using Sindbis virus vectors, and we provide an example of a recent project at our laboratory in which we successfully applied these methods to study thalamocortical projection neurons. Further, we discuss the strengths and limitations of Sindbis virus vectors for single neuron reconstruction, comparing them with adeno-associated virus vectors.

Curcumin prevents the midbrain dopaminergic innervations and locomotor performance deficiencies resulting from chronic Aluminum exposure in rat
Publication date: Available online 4 June 2019Source: Journal of Chemical NeuroanatomyAuthor(s): Wafaa Laabbar, Abdeljalil Elgot, Omar Elhiba, Halima GamraniAbstractAluminum (Al) among the abundant metals on the earth crust, is able to cross the biological barriers via the gastrointestinal and lung tissues. Once in the body, this heavy metal accumulates in different organs, especially the central nervous system.

Noradrenergic terminal density varies among different groups of hypoglossal premotor neurons
Publication date: Available online 22 May 2019Source: Journal of Chemical NeuroanatomyAuthor(s): Caroline E. Boyle, Anjum Parkar, Amanda Barror, Leszek KubinAbstractIn obstructive sleep apnea (OSA) patients, contraction of the muscles of the tongue is needed to protect the upper airway from collapse. During wakefulness, norepinephrine directly excites motoneurons that innervate the tongue and other upper airway muscles but its excitatory effects decline during sleep, thus contributing to OSA. In addition to motoneurons, NE may regulate activity in premotor pathways but little is known about these upstream effects. To start...

Elevated expression of miR-302 cluster improves traumatic brain injury by inhibiting phosphorylation of connexin43 via ERK signaling
We examined apoptosis and ERK1/2 and connexin43 phosphorylation in SH-SY5Y cells undergoing pulsatile shear stress treatment. We assessed expression of miR-302 cluster members and exogenously expressed miR-302 cluster in stressed cells to determine its effect on ERK1/2 and connexin43 phosphorylation. Finally, we investigated the effects of elevated miR-302 expression on cognitive function and brain damage in TBI rats generated by the controlled cortical impact method. Pulsatile shear stress leads to increased apoptosis and upregulation of ERK1/2 and connexin43 phosphorylation in vitro. Additionally, pulsatile shear stress ...

BACE1-AS prevents BACE1 mRNA degradation through the sequestration of BACE1-targeting miRNAs
In this study, we reveal that BACE1-AS shares many miRNA-response elements with BACE1. The overexpression of BACE1-AS results in the repression of miRNAs that target BACE1, thus preventing BACE1 mRNA from being degraded. The knockdown of BACE1-AS increases the levels of these miRNAs, thereby reducing the expression of BACE1. Thus, BACE1-AS functions as a competing endogenous RNA (ceRNA). Our results also deepen the understanding of the regulation of BACE1 by BACE1-AS. In addition to increasing the stability of BACE1 mRNA through the formation of RNA duplexes, BACE1-AS can regulate BACE1 indirectly by acting as a ceRNA. The...

The effects of epothilone D on microtubule degradation and delayed neuronal death in the hippocampus following transient global ischemia
This study examined the effects of pre- and postischemic treatment with different doses of EpoD on the microtubule damage and the delayed neuronal death in the hippocampal CA1 subfield on day 2 following reperfusion after 13-min global cerebral ischemia. Our results showed that systemic treatment with 0.5 mg/kg EpoD only slightly alleviated the microtubule disruption and the CA1 neuronal death, while treatment with 3.0 mg/kg EpoD was not only ineffective against the CA1 neuronal death, but also produced additional damage in the dentate gyrus in some ischemic rats.

Automatic Ground Truth for Deep Learning Stereology of Immunostained Neurons and Microglia in Mouse Neocortex
We report that the throughput efficiency of using ASA to automatically annotate images of Iba1 microglia is more than 5 times greater than that of manual stereology counts of the same sections. Moreover, we show that ASA is significantly more accurate in counting microglia cells than a moderately experienced data collector (about 10% higher overall accuracy) when both were compared to counts by an expert neurohistologist. Thus, the ASA method applied to EDF images from disector stacks can be extremely useful to automate and increase the accuracy of cell counts, which could be especially helpful and cost-effective when expe...

In this study, immunohistochemistry for TRPM3 was conducted in the rat trigeminal, glossopharyngeal and vagal sensory ganglia. TRPM3-immunoreactivity was expressed by half of sensory neurons in the trigeminal (TG), petrosal (PG) and jugular ganglia (JG), and by about 80% of sensory neurons in the nodose ganglion (NG). They mostly had small to medium-sized cell bodies. A trichrome immunofluorescence method showed co-existence of TRPM3 with TRP vanilloid 1 (TRPV1) and calcitonin gene-related peptide (CGRP). Approximately 70% of TRPM3-immunoreactive (-IR) neurons contained TRPV1-immunoreactivity in all the examined ganglia. M...

UMSC-derived exosomes promote retinal ganglion cells survival in a rat model of optic nerve crush
Publication date: Available online 10 January 2019Source: Journal of Chemical NeuroanatomyAuthor(s): Dongyan Pan, Xin Chang, Mengqiao Xu, Mingke Zhang, Shoumei Zhang, Yue Wang, Xueting Luo, Jiajun Xu, Xiangqun Yang, Xiaodong SunAbstractTraumatic optic neuropathy or glaucoma lead to retinal ganglion cells loss and cause blindness, and there is no effective therapy strategy by far. Mesenchymal cells from the Wharton’s jelly of the umbilical cord (umbilical cord mesenchymal stem cells, UMSCs) and UMSC-derived exosomes (UMSC-Exos) are promising candidates for allogeneic therapy in regenerative medicine, but their effort ...

Differentiation of human mesenchymal stem cells (MSC) to dopaminergic neurons: A comparison between Wharton’s Jelly and olfactory mucosa as sources of MSCs
Publication date: Available online 10 January 2019Source: Journal of Chemical NeuroanatomyAuthor(s): Rafieh Alizadeh, Zohreh Bagher, Seyed Kamran Kamrava, Masoumeh Falah, Hatef Ghasemi Hamidabadi, Mahdi Eskandarian Boroujeni, Fatemeh Mohammadi, Sepideh Khodaverdi, Arash Zare-Sadeghi, Arta Olya, Ali KomeiliAbstractThe generation of dopaminergic neurons from stem cells is a potential therapeutic approach to treat neurodegenerative disorders, such as Parkinson’s disease. The current study aims to investigate the potential of two different types of mesenchymal stem cells derived from human Wharton’s jelly and nasal...
