Post-Mortem MRI and Histopathology in Neurologic Disease:A Translational Approach

引用

Neuroscience Bulletin 2019年第2期35卷 229-243页

作者： Laura E.Jonkman Boyd Kenkhuis Jeroen J.G.Geurts Wilma D.J.van de berg Department of Anatomy and Neurosciences Amsterdam Neuroscience Amsterdam UMC Vrije Universiteit Amsterdam Department of Human Genetics Leiden University Medical Center Department of Radiology Leiden University Medical Center

In this review, combined post-mortem brain magnetic resonance imaging(MRI) and histology studies are highlighted, illustrating the relevance of translational approaches to de?ne novel MRI signatures of neuropathological lesions in neuroin?ammatory and neurodegenerative disorders. Initial studies combining post-mortem MRI and histology have validated various MRI sequences,assessing their sensitivity and speci?city as diagnostic biomarkers in neurologic disease. More recent studies have focused on de?ning new radiological(bio)markers and implementing them in the clinical(research) setting. By combining neurological and neuroanatomical expertise with radiological development and pathological validation,a cycle emerges that allows for the discovery of novel MRI biomarkers to be implemented in vivo. Examples of this cycle are presented for multiple sclerosis, Alzheimer's disease, Parkinson's disease, and traumatic brain *** applications have been shown to be successful, while others require further validation. In conclusion, there is much to explore with post-mortem MRI and histology studies, which can eventually be of high relevance for clinical practice.

Ternary III-V nanowires （NWs） cover a wide range of wavelengths in the solar spectrum and would greatly benefit from being synthesized as position-controlled arrays for improved vertical yield, reproducibility, and tunable optical absorption. Here, we report on successful selective-area epitaxy of metal-particle-free vertical InxGa1-xP NW arrays using metal-organic vapor phase epitaxy and detail their optical properties. A systematic growth study establishes the range of suitable growth parameters to obtain uniform NW growth over a large array. The optical properties of the NWs were characterized by room-temperature cathodoluminescence spectroscopy. Tunability of the emission wavelength from 870 nm to approximately 800 nm was achieved. Transmission electron microscopy and energy dispersive X-ray measurements performed on cross- section samples revealed a pure wurtzite crystal structure with very few stacking faults and a slight composition gradient along the NW growth axis.

Development of the Sea Urchin Arbacia Punctulata in the Presence of the Environmental Toxin Sodium Hypochlorite

引用

Journal of Environmental Protection 2011年第8期2卷 1127-1133页

作者： Meghan O. Rock Elizabeth c. Davis-berg Brittan A. Wilson 不详

Sodium hypochlorite (NaOcl) or bleach, found in effluent from wastewater treatment plants, can act as an environmental toxin. The sea urchin Arbacia punctulata is a common subject of embryological toxicity tests due to its sensitivity to environmental pollutants. Using concentrations of NaOcl that mimic those found in treated wastewater (0.11 ppm, 0.06 ppm, and 0.03 ppm) we observed minimal affects on early larval development, though most larvae took longer to develop at higher NaOcl concentration. There was a significant difference in the percentage of non-normal plutei based on concentration (P = 0.038) and significant interaction between the percent of each morphology and NaOcl concentration (P = 0.0027). The most significant change in non-normal plutei was in the retarded (shortened skeletal rods) malformation which increased in frequency with NaOcl concentration (P = 0.001). There was a significant reduction in skeletal length in both normal and retarded plutei (P cl increased.

World Journal of cardiology 2015年第3期7卷 150-156页

作者： Roel JR Snijder Maarten J Suttorp Jurrien M Ten berg Martijn c Post Department of cardiology St.Antonius Hospital

AIM: To investigate long-term efficacy of two different devices more than five years after percutaneous atrial septal defect(ASD) closure in ***: All patients who underwent percutaneous closure of an ASD in the St. Antonius Hospital, Nieuwegein, The Netherlands, between February 1998 and December 2006 were included. Percutaneous closure took place under general anaesthesia and transesophageal echocardiographic moni toring. Transthoracic echocardiography(TTE) was performed 24 h post-procedure to visualize the device position and to look for residual shunting using color Doppler. All complications were registered. All patients were invited for an outpatient visit and contrast TTE more than 5-years after closure. Efficacy was based on the presence of a residual right-to-left shunt(RLS), graded as minimal, moderate or severe. The presence of a residual left-to-right shunt(LRS) was diagnosed using color Doppler, and was not graded. Descriptive statistics were used for patients' characteristics. Univariate analysis was used to identify predictors for residual ***: In total, 104 patients(mean age 45.5 ± 17.1 years) underwent percutaneous ASD closure using an Amplatzer device(ASO) in 76 patients and a cardioseal/Starflex device(cS/SF) in 28 patients. The mean follow-up was 6.4 ± 3.4 years. Device migration occurred in 4 patients of whom two cases occurred during the index hospitalization(1 ASO, 1 cS/SF). The other 2 cases of device migration occurred during the first 6 mo of follow-up(2 cS/SF). The recurrent thrombo-embolic event rate was similar in both groups: 0.4% per follow-up year. More than 12 mo post-ASD closure and latest follow-up, new-onset supraventricular tachyarrhythmia's occurred in 3.9% and 0% for the ASO and cS/SF group, respectively. The RLS rate at latest follow-up was 17.4%(minimal 10.9%, moderate 2.2%, severe 4.3%) and 45.5%(minimal 27.3%, moderate 18.2%, severe 0%) for the ASO- and cS/SF groups, respectively.
