UNLABELLED Cerebral amyloid angiopathy (CAA) is known to be an important cause of spontaneous cortical-subcortical intracranial hemorrhage in normotensive older persons. CAA can also manifest as leukoencephalopathy, brain atrophy, and ischemia secondary to hypoperfusion. Our goal was to verify cerebral hypoperfusion in patients with CAA using (99m)Tc-ethylcysteinate dimer ((99m)Tc-ECD) brain pe...

PURPOSE OF THE REPORT There is a paucity of data on correlation of various imaging modalities with clinical findings in craniosynostosis. Moreover, no study has specifically reported the role of (99m)Tc-ECD SPECT in a large number of subjects with craniosynostosis. MATERIALS AND METHODS We prospectively analyzed a cohort of 85 patients with craniosynostosis from year 2007 to 2012. All patient...

The reliability of diagnostic strategies based on compression ultrasonography (CUS) for the diagnosis of proximal deep venous thrombosis (DVT) in symptomatic (out)patients is well documented; however these approaches never gained widespread application.Echo-color-Doppler (ECD), is regularly adopted by vascular laboratories as first line test in case of clinically suspected DVT, although the spe...

The aim of this study is to develop a copolymer-based single-photon emission computed tomography/magnetic resonance (SPECT/MR) dual-modality imaging agent that can be labeled with both technetium-99m (99mTc) and gadolinium (Gd) and target asialoglycoprotein receptor (ASGPR) via galactose. Monomers of N-p-vinylbenzyl-6-(2-(4-dimethylamino)benzaldehydehydrazono) nicotinate (VNI) for labeling of 9...

A novel tetrathiafulvalene dimer, bridged by a chiral 1,3-diphenylallene framework, has been prepared as an optically active compound having strong chiroptical properties. Although a chiral allene bearing strong electron-donating group(s) often undergoes slow photoracemization even in daylight, the present allene is totally configurationally stable under ordinary conditions. Each isomer possess...

Objective: The development of new radiopharmaceuticals capable specifically imaging cancer is an important research area. For this reason, the aim study to investigate cell binding novel developed nanoradiopharmaceutical ([99mTc]Tc-nab-PTX) on HT-29 line (human colorectal adenocarcinoma cells).
 Material and Method: In study, nab-PTX was labeled with [99mTc]Tc, labeling efficiency in vitro...

Delitschiapyrone A (1), an α-pyrone-naphthalenone adduct with an unprecedented pentacyclic ring system, was isolated from a solid culture of the leaf-associated fungus Delitschia sp. FL1581. The structure of 1 was elucidated by spectroscopic analysis and X-ray crystallography, and its absolute configuration was defined by experimental and calculated ECD. Biosynthetically, the unique 6/6/5/7/6 p...

We herein report a 65-year-old man demonstrating dementia with Lewy bodies who first presented with Bálint's syndrome. Two years later, a mild cognitive impairment was noted. From three years after onset, he developed progressive parkinsonism, visual hallucination, and autonomic dysfunction, in line with the deterioration of the cognitive function. Single photon emission computed tomography wit...

Ephedra sinica, an important plant in Chinese traditional medicine, contains a complex mixture of proanthocyanidin oligomers as major constituents; however, only the minor components have been chemically characterized. In this study, oligomers with relatively large molecular weights, which form the main body of the proanthocyanidin fractions, were separated by adsorption and size-exclusion chro...
