Ultra-Fast-Charging, Long-Duration, and Wide-Temperature-Range Sodium Storage Enabled by Multiwalled Carbon Nanotube-Hybridized Biphasic Polyanion-Type Phosphate Cathode Materials.

Sodium-ion batteries (SIBs) represent a promising energy storage technology with great safety. Because of their high operating potential, superior structural stability, and prominent thermal stability, polyanion-type phosphates have garnered significant interest in superior prospective cathode materials for SIBs. Nevertheless, the disadvantages of poor intrinsic electronic conductivity, sluggish kinetics, and volume variation during sodiation/desodiation remain great challenges for satisfactory rate performance and cycle stability, which severely hinder their further practical applications.

Adenomyoma of the distal common bile duct demonstrated by endoscopic ultrasound: A case report and review of the literature.

Background: Adenomyomatous hyperplasia of the distal common bile duct (CBD) is very rare, with only scarce case reports in the literature. Diagnosis is usually based on imaging findings, and endoscopic biopsy is very difficult before operation. It is believed that adenomyomatous hyperplasia has little or no risk of malignant transformation.

Breaking the reduced glutathione-activated antioxidant defence for enhanced photodynamic therapy.

Photodynamic therapy (PDT) has been applied in cancer treatment by utilizing reactive oxygen species (ROSs) to kill cancer cells. However, a high concentration of reduced glutathione (GSH) is present in cancer cells and can consume ROSs and sharply reduce the PDT activity. To address this problem, herein, we synthesized a thymine modified Zn phthalocyanine (ZnPc, a monomer and an active form for PDT) and prepared its nanoparticle form (an aggregator and an inactive form) with Hg providing the driving force for the "thymine-Hg-thymine" interaction.

Totally laparoscopic gallbladder-preserving surgery: A minimally invasive and favorable approach for cholelithiasis.

The aim of the present study was to investigate the effectiveness of laparoscopic gallbladder-preserving surgery (L-GPS) for cholelithiasis and the feasibility and value of totally laparoscopic GPS (TL-GPS). A total of 517 patients underwent L-GPS, including 365 cases of laparoscopy-assisted GPS (LA-GPS), 143 cases of TL-GPS (preservation rate, 98.3%) and nine conversions to laparoscopic cholecystectomy.

Arginine-assisted synthesis and catalytic properties of single-crystalline palladium tetrapods.

Noble metallic nanocrystals (NMNCs) with highly branched morphologies are an exciting new class of nanomaterials because of their great potential application in catalysis, sensing, optics, and electronics originating from their unique structures. Herein, we report a facile water-based method to synthesize high-quality palladium (Pd) tetrapods with the assistance of arginine molecule, which is more economical and environmentally friendly than the previous reported carbon monoxide (CO)-assisted synthesis in the organic system. During the synthesis, arginine molecule plays an essential role in controlling the tetrapod-like morphology.

Disturbance of autophagy-lysosome signaling molecule expression in human gastric adenocarcinoma.

Autophagy is classified as type II programmed cell death and may participate in tumorigenesis. However, changes in autophagy-lysosome signaling and the relationship between the apoptotic cascade and gastric cancer cells have not been fully elucidated. The present study investigated the induction of autophagy in poorly differentiated human gastric adenocarcinoma.

Growth inhibitory effect of KYKZL-1 on Hep G2 cells via inhibition of AA metabolites and caspase-3 pathway and cell cycle arrest.

KYKZL-1, a newly synthesized compound with COX/5-LOX dual inhibition, was subjected to the inhibitory activity test on Hep G2 growth. We found that KYKZL-1 inhibited the growth of Hep G2 cells via inducing apoptosis. Further studies showed that KYKZL-1 activated caspase-3 through cytochrome c release from mitochondria and down regulation of Bcl-2/Bax ratio and reduced the high level of COX-2 and 5-LOX.

Inhibition of inflammatory mediators contributes to the anti-inflammatory activity of KYKZL-1 via MAPK and NF-κB pathway.

KYKZL-1, a newly synthesized compound with COX/5-LOX dual inhibition, was subjected to the anti-inflammatory activity test focusing on its modulation of inflammatory mediators as well as intracellular MAPK and NF-κB signaling pathways. In acute ear edema model, pretreatment with KYKZL-1 (p.o.

Inhibition of proliferation of estrogen receptor‑positive MCF‑7 human breast cancer cells by tamoxifen through c‑Jun transcription factors.

Activator of protein 1 (AP-1) is a heterodimeric transcription factor composed of various members of the Jun and Fos families and binds to DNA at specific AP-1 binding sites. AP-1 transcriptional activity is increased by phosphorylation at serine residues in the c‑Jun component of AP-1. In the present study, the proliferation of MCF-7 breast cancer cells was found to be suppressed by tamoxifen (TAM)-activated c-Jun through the protein kinase C (PKC) pathway.

Characterization and photodynamic activity of a new phthalocyanine nanoparticles.

Nanoparticles of a hydrophobic photosensitizer, tetrakis (3-trifluoromethylphenoxy) zinc phthalocyanine (FPcZn) have been synthesized by using a simple reprecipitation technique. The resulting drug nanoparticles (FPcZn-NP) were spherical, highly monodispersed and stable in aqueous system, without an additional stabilizer. Comparative studies with FPcZn-NP and FPcZn indicated that after the formation of nanoparticles, FPcZn-NP maintained the efficiency of (1)O(2) generation.

A new hypocrellin A (HA) encapsulated silica nanoparticles was prepared by an improved microemulsion method based on the unique character of cetyl trimethyl ammonium bromide (CTAB). Stable aqueous dispersions of the HA-loaded nanoparticles, with the diameter about 50 nm, owned superior photo-stability and singlet oxygen generation ability to free HA. In vitro studies demonstrated the active uptake of HA-doped nanoparticles into the cytosol of HeLa (human cervix epithelioid carcinoma) cells.

Mitochondria-targeting photosensitizer-encapsulated amorphous nanocage as a bimodal reagent for drug delivery and biodiagnose in vitro.

The use of ceramic nano-carriers containing anti-cancer drugs for targeted delivery that span both fundamental and applied research has attracted the interest of the scientific community. In this paper, a hydrophobic photodynamic therapy drug, hypocrellin A (HA), was successfully encapsulated in water-soluble amorphous silica nanocage (HANC) by an improved sol-gel method. These nanocages are of ultrasmall size, highly monodispersed, stable in aqueous suspension, and retain the optical properties of HA.

[Study on the interaction between p-HPcZn and myoglobin].

The interaction of p-HPcZn and myoglobin was studied by fluorescence spectra and synchronous fluorescence spectra methods under the physiological condition. The p-HPcZn can quench the fluorescence of myoglobin effectively, and it is indicated that there is a strong interaction occurring between p-HPcZn and myoglobin. The results of the fluorescence spectra with changing temperature proved that the interaction can lead to the formation of complex of p-HPcZn with myoglobin, and quench the fluorescence of myoglobin through the static quenching mechanism.
