Rapid advances in DNA synthesis techniques have made it possible to engineer viruses, biochemical pathways and assemble bacterial genomes. Here, we report the synthesis of a functional 272,871-base pair designer eukaryotic chromosome, synIII, which is based on the 316,617-base pair native Saccharomyces cerevisiae chromosome III. Changes to synIII include(More)
The interaction between jatrorrhizine (JAT) and bovine serum albumin (BSA) has been studied. The studies were carried out in a buffer medium at pH 7.4 using fluorescence spectroscopy, UV–vis spectroscopy, and molecular modeling methods. The results of fluorescence quenching and UV–vis absorption spectra experiments indicated the formation of the complex of(More)
The purpose of this study was to determine the reliability of applying conventional anatomical landmarks to locate venous sinus in posterior fossa using subtraction computed tomography angiography (CTA) technique. We retrospectively reconstructed transverse sinus (TS), sigmoid sinus (SS), and cranial imaging from 100 patients undergoing head CTA(More)
In this study, we used morin as a reducing agent for the synthesis of stable and nearly spherical Au nanoparticles (M-AuNPs), which were characterized by UV-vis, transmission electron microscopy (TEM) and X-ray diffraction (XRD). The binding characteristics and molecular mechanism of the interaction between the M-AuNPs and bovine serum albumin (BSA) were(More)
PURPOSE Previous studies have detected abnormal iron deposition in the deep grey matter (DGM) of multiple sclerosis (MS). The regional specificity of the DGM iron deposition in neuromyelitis optica (NMO) is still unclear. We compared the differences in the DGM iron concentration between MS and NMO patients. METHODS We enrolled 42 relapsing-remitting MS(More)
OBJECTIVE The purpose of this study was to determine whether proton MR spectroscopy ((1)H MRS) and diffusion-weighted (DW) imaging can be used to differentiate intracranial tuberculomas from high grade gliomas (HGGs). MATERIALS AND METHODS A total of 41 patients (19 with intracranial tuberculomas and 22 with HGGs) were examined in our study. (1)H MRS and(More)
Laser speckle contrast imaging (LSCI) is a contrast agent free imaging technique suited for longitudinal assessment of vascular remodeling that accompanies brain tumor growth. We report the use of LSCI to monitor vascular changes in a rodent glioma model. Ten rats are inoculated with 9L gliosarcoma cells, and the angiogenic response is monitored five times(More)
This paper exploring the site-selective binding of jatrorrhizine to human serum albumin (HSA) under physiological conditions (pH=7.4). The investigation was carried out using fluorescence spectroscopy, UV-vis spectroscopy, and molecular modeling. The results of fluorescence quenching and UV-vis absorption spectra experiments indicated the formation of the(More)
In order to extend the antibacterial time of quaternary phosphonium salt in bacteria, palygorskite (PGS) is used as the carrier of dodecyl triphenyl phosphonium bromide (DTP), and a DTP-PGS hybrid is prepared. Antibacterial performance of this novel hybrid is investigated for both Gram-positive and Gram-negative bacteria. The results show that the DTP could(More)
To investigate characteristics of the internal cerebral veins (ICVs) and their main tributaries and the deep medullary veins (DMVs) in patients with relapsing-remitting MS (RRMS) with enhanced T 2 * -weighted angiography imaging (ESWAN). Fifty-three RRMS patients and 53 normal controls underwent conventional MRI and ESWAN. ESWAN venograms were created by(More)
