MMP-9, Vertebrobasilar Ectasia and Vertebral Artery Dominance in Vertigo or Dizziness Patients With Vascular Risk Factors.

Although vertebrobasilar ectasia (VBE) is diagnosed with increasing frequency, it is not clear whether this is because of altered hemodynamics caused by the effects of matrix metalloproteinases (MMPs) and/or vertebral artery dominance (VAD). Therefore, we investigate the relationship between plasma levels of MMPs and VBE in patients with vertigo or dizziness who also have vascular risk factors, in order to determine whether high levels of MMPs in VBE are independent of VAD. We prospectively studied 285 patients with vertigo or dizziness and at least one vascular risk factor.

Magnetic resonance imaging evaluation of Wallerian degeneration of bilateral middle cerebellar peduncles after pontine infarction.

We aimed to present a case of symmetrical Wallerian degeneration (WD) in the middle cerebellar peduncles (MCPs) after a unilateral paramedian pontine infarction, which was examined by multimodality magnetic resonance imaging (MRI). In addition, we summarize the small number of reported cases. In our clinic, we observed a case of symmetrical WD of bilateral MCPs that occurred 6 months after the onset of a pontine infarction.

Basilar Artery Tortuosity Is Associated With White Matter Hyperintensities by TIMP-1.

Background And Purpose: To test the hypothesis that the imbalance between matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinases (TIMPs) may play a potential role in bridging vertebrobasilar dolichoectasia (VBD) with lacunar infarction (LI) and white matter hyperintensities (WMH).

Methods: We studied 212 patients with vertigo who underwent multimodal magnetic resonance imaging (MRI) tests for VBD, LI, and WMH identification. We investigated biomarkers of VBD with magnetic resonance angiography (MRA) via various physical characteristics of the vertebrobasilar arteries (VBAs).

Perfusion by delayed time to peak in vertebrobasilar dolichoectasia patients with vertigo.

Objective: To investigate the association between the perfusion magnetic resonance imaging (MRI) and vertebrobasilar dolichoectasia (VBD) in vertigo patients and at least one vascular risk factor.

Methods: We studied 289 patients with vertigo (spinning, swaying, nausea, vomiting, and unsteady gait) who performed multimode MRI. Maximum diameter and tortuous parameters of the basilar artery and vertebral arteries were calculated using magnetic resonance angiography.

Prevalence of Stroke and Hypoperfusion in Patients With Isolated Vertigo and Vascular Risk Factors.

The aim of this study was to determine the prevalence and associated factors of stroke and hypoperfusion among patients with isolated vertigo and vascular risk factors. We studied 157 patients with isolated vertigo who had undergone multimodal magnetic resonance imaging. Magnetic resonance angiography (MRA) was used to measure the diameters of vertebrobasilar arteries and to evaluate morphologic changes to vessels.

Why does my patient's basilar artery continue to grow? A four-year case study of a patient with symptoms of vertebrobasilar dolichoectasia.

Background: Vertebrobasilar dolichoectasia (VBD) is a clinical entity associated with ischemic stroke, compression of cranial nerves or brainstem, and hydrocephalus. There have been relatively few studies following the progression of VBD in patients presenting with a variety of diverse clinical features.

Case Presentation: Here, we report a case study of a male with progressive VBD who was followed from November 2012 to December 2016.

A novel three-dimensional cadmium(II) coordination polymer incorporating 1,4-bis(1,2,4-triazol-1-ylmethyl)benzene and thiocyanate.

In the title complex, poly[cadmiumII-mu2-1,4-bis(1,2,4-triazol-1-ylmethyl)benzene-di-mu2-thiocyanato], [Cd(NCS)2(C12H12N6)]n, the CdII atom lies on an inversion centre in a distorted octahedral environment. Four N atoms from the thiocyanate and 1,4-bis(1,2,4-triazol-1-ylmethyl)benzene (bbtz) ligands occupy the equatorial positions, and two S atoms from symmetry-related thiocyanate ligands occupy the axial positions. The benzene ring of the bbtz ligand lies about an inversion centre.
