This study aimed to create a glycyrrhetinic acid (GA)-mediated, multi-component, self-assembled nano-drug delivery system co-loaded with syringopicroside (S) and hydroxytyrosol (H) obtained from by synthesizing a GA-polyethylene glycol-poly (lactic acid-co-glycolic acid) (GPP) nanoparticle delivery carrier to actively target the liver. The nanoparticles were optimized using the central composite design. Nanoparticle characterization, cytotoxicity, pharmacodynamics, and tissue distribution study were performed.

As a new class of national anti-infective drugs, carrimycin (CAM) has strong activity against gram-positive bacteria and no cross resistance with similar drugs. Studies have shown that the components of CAM have anticancer effects.

Syringopicroside (SYR) and Hydroxytyrosol (HT), the active components of the Chinese herb Lindl, have earned great reputation for their potential in preventing or treating viral hepatitis type B. Therefore, we loaded SYR and HT into GA-conjugated PEG-PLGA, so that they could target the liver in additional to exerting their own pharmacological effects in a synergistic.

The ABAC exhibited maximum adsorption capacity of RhB (1101 ± 11 mg/g), higher than that of laboratory-prepared rape straw activated carbon (176 ± 5 mg/g) and commercial activated carbon (489 ± 5 mg/g). It is attributed to larger surface area and mesoporous structure of the ABAC.

Bio-electrochemical systems are efficient to promote electrons transfer between microbes and pollutants to improve the degradation of refractory contaminants. In particular, three-dimensional biofilm electrode reactors (3DBERs), integrating the biofilm with particle electrodes, represent a novel bio-electrochemical technology with superior treatment performances.

Conventional biological technology such as anaerobic-anoxic-oxic (AO) system is inefficient, since various biological reactions are inhibited by toxicants in coking wastewater. In this work, a pilot-scale three-dimensional electrochemical reactor (3DER) is integrated into the AO system as a pretreatment unit to improve the treatment efficiency of coking wastewater.

Particle electrodes filled between anode and cathode are the core units of 3DER, determining the treatment efficiency of wastewater. However, particle electrodes deactivation due to catalytic sites coverage seriously impedes the continuous operation of 3DER.

Because the bristle-shaped structure with electric conductivity could overcome the obstacle of hair and enable direct connection to scalp, the semi-dry electrode could work with drinking water instead of saline water that was widely used in previous semi-dry or water electrodes to improve its convenience. The electrode consisted of conductive bristles and a 3D-printed casing.

Natural organic matters (NOM) existed in the environments are considered to have the capacity of binding with organic contaminants, consequently influencing their speciation and transformation in the natural environments. To assess the migration of antibiotics in the environments, it is crucial to understand the binding mechanisms between NOM and antibiotics, which is still unclear due to the limit of available research methods.

This transformation proceeds via the in situ formation of isothiocyanate intermediates, followed by a [3,3]-sigmatropic rearrangement. The resulting allenyl thiocyanates bearing 3-(electro-donating phenyl) substitutions without isolation can then be reacted with di- tert-butyl peroxide and AgSCF under reflux to generate novel allenyl trifluoromethylthioether compounds in moderate to good yields via a "one-pot" three-step process.

Objective: To explore the value of CD3CD4 T cell count in prediction of viral infections after allogeneic hematopoietic stem cell transplantation(allo-HSCT) in the patients with severe aplastic anemia(SAA).
Methods: A total of 78 SAA patients with allo-HSCT in Guangzhou First People's Hospital from January 2014 to July 2016 were enrolled in this study. The absolute numbers of CD3CD4T cells were measured by flow cytometry at 1,2,3,6, and 12 month after allo-HSCT.
Plasmonic-induced optical transparency with double split nanoring cavity is investigated with finite difference time domain method. The coupling between the bright third-order mode of split nanoring with one gap and the dark quadrupole mode of split nanoring with two gaps leads to plasmonic analogue of electromagnetically induced transparency. The transparence window is easily modified to the near-infrared and visible range.
