In order to elucidate the digestion, absorption and metabolism mechanism, Hohenbuehelia serotina polysaccharides were successfully labelled by fluorescein isothiocyanate (FITC-Tyr-HSP), with the fluorescent substitution degree of 0.37 %. FITC-Tyr-HSP with excellent physiological stability possessed the significant fluorescent characteristics, which could be dynamically monitored by in vivo fluorescence imaging and high performance gel permeation chromatography-fluorescence detector (HPGPC-FLD).

Developing near-infrared fluorescent probes for simultaneous tracking of lipid droplets (LDs) and lysosomes is highly desirable for studying cell metabolism. In this work, deep-red/near-infrared dual-emission carbonized polymer dots (DN-CPDs) were prepared for ratiometric monitoring of the intracellular polarity. Detailed structural analysis revealed that the deep-red emission and near-infrared peak of DN-CPDs originate from the molecular state and surface state, respectively.

The use of lithium-rich manganese-based oxides (LRMOs) as the cathode in all-solid-state batteries (ASSBs) holds great potential for realizing high energy density over 600 Wh kg. However, their implementation is significantly hindered by the sluggish kinetics and inferior reversibility of anionic redox reactions of oxygen in ASSBs. In this contribution, boron ions (B) doping and 3D LiBO (LBO) ionic networks construction are synchronously introduced into LRMO materials (LBO-LRMO) by mechanochemical and subsequent thermally driven diffusion method.

The point-of-care testing (POCT) of electrochemical biosensors is hindered by biofouling and signal sensitivity. Sometimes the antifouling strategies were used by decreasing the electroconductivity. Addressing the conductivity-antifouling trade-off in electrochemical sensors, we synthesized a novel conductive and antifouling nucleoside hydrogel (C-Ag-C hydrogel).

Redox-responsive self-assembled prodrug nanoparticles have received extensive attention for their high loading efficiency and environmentally responsive properties. However, the intracellular metabolism and transportation kinetics were poorly understood, which limited the rational design and development of this delivery system. Herein, tetraphenylporphyrin-paclitaxel (TxP) prodrugs with thioether, disulfide, and dicarbon linkers (TsP, TssP, and TccP) were synthesized and self-assembled as nanoparticles.

PARP inhibitors sensitize pancreatic ductal adenocarcinoma (PDAC) to radiation by inducing DNA damage and replication stress. These mechanisms also have the potential to enhance radiation-induced type I interferon (T1IFN)-mediated antitumoral immune responses. We hypothesized that the PARP inhibitor olaparib would also potentiate radiation-induced T1IFN to promote antitumor immune responses and sensitization of otherwise resistant PDAC to immunotherapy.

The development of widely sourced and efficient adsorbents is crucial for the adsorption of lead from wastewater. A novel adsorbent, N-doped weathered coal (NWC), was prepared in this study using weathered coal as the precursor and triethylenetetramine (TETA) as the N-source. The adsorption performance and behavior of Pb(II) on NWC were investigated using batch adsorption experiments.

Blueberry is one of the most perishable fruits, and the postharvest supply chain environment temperature has great effects on fruit quality. In order to determine the critical steps referring to non-optimal conditions and the key quality indexes in response to temperature along the cold chain, 15 time-temperature scenarios were conducted simultaneously for the storage of blueberry fruits and 17 quality attributes were determined. The results indicated that different cold chain steps under abusing temperatures significantly affected blueberry qualities.

Circadian rhythm, regulated by a time keeping system termed as the circadian clock, is important for many biological processes in eukaryotes. Disordered circadian rhythm is implicated in different human diseases, including cardiovascular disease, neurologic disease, metabolic disorders, and cancer. The stem like-cancer cells (or cancer stem cells, CSCs) are proposed to stand at the top of the heterogeneous hierarchy in different solid tumors, which are responsible for tumor initiation, development, therapy resistance and metastasis.

Previous studies have demonstrated that the donor (D)-acceptor (A) structure enables conjugated polymers (CPs) to effectively inhibit charge recombination, reduce exciton binding energy to a minimum, and broaden the light absorption spectrum, ultimately enhancing photocatalytic activity. Besides, side chain engineering is an effective approach to enhance photocatalytic performance by regulating surface chemistry and energy band structure of CPs. Herein, three D-A type CPs, namely TPD-T, TPD-MOT and TPD-DOT, were designed and synthesized using thieno[3,4-c]pyrrole-4,6-dione (TPD) as A units and thiophene with different alkyl/alkoxy groups side chain (as 3-octylthiophene (T), 3-methoxythiophene (MOT) and 3,4-ethylenedioxythiophene (DOT)) as D units, via an atom- and step-economic CH/CH cross-coupling polycondensation.

The oxidative C2-C3 π bond activation strategy is the most efficient tool to synthesize oxygen-containing indoline, which frequently appears in natural products with various biological activities as structural units. Recently, the oxidation-induced cascade strategy through oxygenation activation of the indolic C2-C3 π bond of indoles has received much attention for its use in efficiently establishing complex indoline with oxygen-containing molecular architectures, and holds tremendous potential in the total synthesis of indole alkaloids. It can be carried out using potential activated indole radical cations or imine cation intermediates produced oxidative C2-C3 π bond activation of indole with various nucleophiles or ring-forming reagents by employing simple and non-decorated indoles as starting substrates.

Land-based mazes that require spatial cues to identify the location of a hiding-place are a low-stress method to evaluate learning rate and memory retention in mice. One version, the Barnes maze, allows quantification of naturalistic exploratory behaviors not evident in water-based tasks. As the task relies on innate behaviors, it does not require overtraining, making it more feasible to examine early learning and non-memory executive functions that are characteristic of some non-amnestic dementias.
