Spatiotemporal expression of NDRG2 in the human fetal brain.
In this study, we examined the expression pattern of NDRG2 in different regions of human fetal brain at 16-28 gestational weeks (GWs) by using RT-PCR, western blot and immunohistochemistry. Firstly, RT-PCR revealed that mRNA of NDRG2 was detected in the human brain regions of fetuses at 16-28 GWs such as medulla oblongata (MdO), mesencephalon (MeE), cerebellum (Cbl), frontal lobe (Fr), ventricular (VZ)/subventricular zone (SVZ) and hippocampus (hip), and the expressions of NDRG2 mRNA in these human fetal brain regions were increased with gestational maturation. Furthermore, western blot and immunohistochemistry results rev...

Mapping the intersection of language and reading: the neural bases of the primary systems hypothesis
This study provided the first quantitative investigation of this account at both behavioural and neural levels in a group of patients with chronic post-stroke aphasia. Principal components analysis was used to distil orthogonal measures of phonological and semantic processing, which were then related to reading performance and the underlying lesion distributions using voxel-based correlational methodology. Concrete word reading involved both a ventral semantic pathway, and inferior and anterior aspects of the dorsal phonological pathway. Abstract word reading overlapped with the ventral semantic pathway but also drew more ...

Cardiac telocytes. From basic science to cardiac diseases. I. Atrial fibrillation.
CONCLUSIONS: Even if a few articles implied a potential association between AF and telocytes, the current data is not enough to support it. Moreover, even an association between the morphology, characteristics, or density of the telocytes in the atrium/pulmonary veins and AF is potentially speculative, and more studies should be performed before implying it with a reasonable degree of certainty.

Variations in carotid sinus anatomy and their relevance to carotid interventions.
CONCLUSIONS: Clinicians performing carotid interventions should be aware of these anatomical variations to avoid inadvertent stimulation of the CS which can cause profound bradycardia and hypotension. PMID: 29500893 [PubMed - as supplied by publisher]

Porcine heart interatrial septum anatomy.
CONCLUSIONS: There are significant differences between human and porcine interatrial septum morphology that should be taken into account during experimental studies. The absence of the left SP in swine results in the inability to use porcine heart as an experimental model for left-sided SP management. PMID: 29458135 [PubMed - as supplied by publisher]

Right –left propensity of cardiogenic cerebral embolism in standard versus bovine aortic arch variant
Left‐hemispheric ischemic strokes are more frequent overall and often have a worse outcome than their right‐hemispheric counterparts. We hypothesized that the right‐left propensity of CE cerebral infarcts differs between patients with standard and bovine arch variants. We retrospectively identified all patients with acute stroke of the anterior circulation admitted to our primary stroke center between January 2011 and June 2017 who had moderate‐ to high‐risk cardio‐embolic sources according to the SSS‐TOAST classification. From amongst these patients, only those with available cross‐sectional imaging of the...

Right ‐Left Propensity of Cardiogenic Cerebral Embolism in Standard versus Bovine Aortic Arch Variant
Conclusion: No statistically significant difference in embolic stroke laterality was demonstrated in our relatively small sample. Bovine arch could be an independent risk factor for cardio‐embolic embolism. This article is protected by copyright. All rights reserved.

Using anatomical landmark to avoid phrenic nerve injury during balloon-based procedures in atrial fibrillation patients
ConclusionUsing the lateral border of the sixth thoracic vertebra as a landmark, which can be viewed under fluoroscopy during the procedure, physicians can triangulate the distance to the RSPV and determine the approximate position of the RPN. Furthermore, physicians can perform a preoperative echocardiogram to determine the size of the LA to assist in determining the position of the RPN with the hopes of avoiding injury to the RPN.

Stroke bricks - spatial brain regions to assess ischemic stroke localization.
Authors: Ciszek B, Jóźwiak R, Sobieszczuk E, Przelaskowski A, Skadorwa T Abstract Computer-aided analysis of non-contrast CT (NCCT) images for rapid diagnosis of ischemic stroke is based on the augmented visualization of evolving ischemic lesions. Computerized support of NCCT often leads to overinterpretation of ischemic areas, thus it is of great interest to provide neurologically verified regions in order to improve accuracy of subsequent radiological assessment. We propose Stroke Bricks (StBr) as an arbitrary spatial division of brain tissue into the regions associated with specific clinical symptoms of ischem...

Overexpression of kynurenic acid in stroke: an endogenous neuroprotector?
Abstract It is known that kynurenic acid (KYNA) exerts a neuroprotective effect against the neuronal loss induced by ischemia; acting as a scavenger, and exerting antioxidant action. In order to study the distribution of KYNA, a highly specific monoclonal antibody directed against KYNA was developed. This distribution was studied in control rats and in animals in which a middle cerebral artery occlusion (stroke model) was induced. By double immunohistochemistry, astrocytes containing KYNA and GFAP were exclusively found in the ipsilateral cerebral cortex and/or striatum, at 2, 5 and 21days after the induction of s...

A case of a single intracranial vertebral artery and cerebral infarct.
Authors: Blackburn K, Labranche L, Kalmey J, Kulesza RJ Abstract The vertebral arteries are commonly affected by anatomical variation. This variation ranges from slight asymmetry in arterial diameter between the right and left sides to complete absence of a vertebral artery on one side. Asymmetry in diameter is a common observation, although complete absence of the artery is rare. Herein, we report on a 79-year-old maleanatomical donor who, upon brain removal, was found to have a single intracranial vertebral artery which was the sole source of the basilar artery. During dissection of the neck, both right and left ...

Investigating structure and function in the healthy human brain: validity of acute versus chronic lesion-symptom mapping
AbstractModern voxel-based lesion-symptom mapping (VLSM) analyses techniques provide powerful tools to examine the relationship between structure and function of the healthy human brain. However, there is still uncertainty on the type of and the appropriate time point of imaging and of behavioral testing for such analyses. Here we tested the validity of the three most common combinations of structural imaging data and behavioral scores used in VLSM analyses. Given the established knowledge about the neural substrate of the primary motor system in humans, we asked the mundane question of where the motor system is represente...

Successive motor nerve blocks to identify the muscles causing a spasticity pattern: example of the arm flexion pattern.
Abstract Botulinum Toxin A has been the main treatment for spasticity since the beginning of the 1990s. Surprisingly, there is still no consensus regarding injection parameters or, importantly, how to determine which muscles to target to improve specific functions. The aim of this study was to develop a systematic approach to determine this, using the example of the arm flexion pattern. We first determined anatomical landmarks for selective motor block of the brachialis nerve, using 20 forearms from 10 fresh cadavers in Ecole Européenne de Chirurgie and a university-based dissection centre, Paris, France. We then...

Effects of dorsolateral prefrontal cortex lesion on motor habit and performance assessed with manual grasping and control of force in macaque monkeys
Abstract In the context of an autologous adult neural cell ecosystem (ANCE) transplantation study, four intact adult female macaque monkeys underwent a unilateral biopsy of the dorsolateral prefrontal cortex (dlPFC) to provide the cellular material needed to obtain the ANCE. Monkeys were previously trained to perform quantitative motor (manual dexterity) tasks, namely, the “modified-Brinkman board” task and the “reach and grasp drawer” task. The aim of the present study was to extend preliminary data on the role of the prefrontal cortex in motor habit and test the hypothesis that dlPFC contributes to predi...
