The blackberry seed was typically removed as a byproduct and waste from blackberry fruits for juices. Developing value-added utilization of berry seeds will significantly expand the market for berry products as well as improve benefit to berry producers. However, the research on blackberry seed is limited. The objective of this paper was to research antithrombotic mechanism of polysaccharides in blackberry seeds. Polysaccharides in blackberry seeds were extracted, purified and identified by high-performance gel permeation chromatography (HPSEC), gas chromatography (GC), fourier transform infrared (FT-IR) spectrometer and nuclear magnetic resonance spectra (NMR)...

OBJECTIVE: Use of tumour necrosis factor inhibitors (TNFi) has proved to be an important step forward in the treatment of axial spondyloarthritis (axSpA), but the duration of the therapy as well as the management in case of low disease activity (LDA) or remission are not clearly established. Currently, the identification of potential predictors associated with the treatment discontinuation is the basic purpose of many clinical studies. The aim of this study was to analyze the influence of the discontinuation of TNFi therapy on the disease activity in patients with low disease activity...

Coronaviruses are a major infectious disease threat, and include the pathogenic human pathogens of zoonotic origin: SARS-CoV and MERS-CoV. Entry of coronaviruses into host cells is mediated by the viral spike (S) protein, which is structurally categorized as a class I viral fusion protein, within the same group as influenza virus and HIV. However, S proteins have two distinct cleavage sites that can be activated by a much wider range of proteases. The exact location of the coronavirus fusion peptide (FP) has been disputed...

Radical cations of bis(triarylamine)s, 3 and 4, in which the triarylamine redox centers are bridged by ortho-phenylene and ortho-carborane cluster, respectively, have been prepared to elucidate the difference in intramolecular charge/spin transfer (ICT/IST) pathway due to the two different bridging units affording similar geometrical arrangements between the redox centers. Electrochemistry, absorption spectroscopy, VT-ESR spectroscopy, and DFT calculations reveal that 3*+ and 4*+ are classified into class-II and class-I mixed valence systems, respectively, and therefore, through-bond and through-space mechanisms are dominant for the ICT/IST phenomena in 3*+ and 4*+, respectively...

Yi Xu, Steven Qian
Redox signaling plays important roles in regulating pulmonary vasculature function. Aberrant redox signaling, e.g., overproduction of reactive oxygen species (ROS) that exceeds the capability of cellular antioxidant mechanisms, has been found to alter vasculature function and remodel blood vessel structure, thus contributes to pathological processes of pulmonary vasculature. The regulation of pulmonary vasculature via ROS is a very complicated process with various biological events involved, however, the specific effect of individual ROS and the underlying mechanism still remain unclear...

One-electron oxidation of a Ga(III)-corrole with N(4-BrC6H4)3SbCl6 resulted in an air-stable non-innocent Ga(III)-corrole radical. Single crystal X-ray crystallography of 1,18-bisformyl[(TPFC)Ga(III)-Cl]* revealed delocalization of the unpaired electron, which was further confirmed by electron spin resonance (ESR) spectroscopy and spin density distribution plot. In addition, the nucleus-independent chemical shift (NICS), anisotropy induced-current density (AICD) and harmonic oscillator model of aromaticity (HOMA) supported a [17] pi-electron conjugated (or antiaromatic) radical...

The efficient separation of photogenerated electron-hole pairs in photoactive materials is highly desired, allowing their transfer to specific sites for undergoing redox reaction in various application. The construction of ternary heterojunctions is a practical strategy to enhance the migration of photogenerated electron that realizes the synergistic effect of multi-components rather than the simple overlay of single component. Here, we demonstrate an available way to fabricate new BiOCl/BiVO4/nitrogen-doped graphene quantum dots (N-GQDs) ternary heterojunctions that exhibit higher efficiency in charge separation than any binary heterojunctions or pure materials under visible light irradiation...

Dynamic Nuclear Polarization (DNP) has proven itself most powerful for the orientation of nuclear spins in polarized targets and for hyperpolarization in magnetic resonance imaging (MRI). Unfortunately, the theoretical description of some of the processes involved in DNP invokes the high temperature approximation, in which Boltzmann factors are expanded up to first order, while the high electron and nuclear spin polarization required for many applications do not justify such an approximation. A previous article extended the description of one of the mechanisms of DNP-thermal mixing-beyond the high temperature approximation (Wenckebach, 2017)...
