Functional characterization of obscure puffer ToNK-lysin: A novel immunomodulator possessing anti-bacterial and anti-inflammatory properties.

NK-lysins are one of the most abundant antimicrobial peptides produced by cytotoxic T lymphocytes (CTLs) and natural killer cells (NKs), and identified as a new class of intrinsically disordered proteins, playing critical roles in the cell-mediated cytotoxicity response, as well as immunomodulatory and antimicrobial activities upon a significant range of pathogens. In the present study, an NK-lysin was identified from Obscure puffer Takifugu obscurus (ToNK-lysin). The open reading frame of ToNK-lysin sequence spans 423 bp, encoding a peptide with 140 amino acids which shares a moderate residue identity (18%-60%) with NK-lysin of mammals and other teleost species.

Current and potential roles of immuno-PET/-SPECT in CAR T-cell therapy.

Chimeric antigen receptor (CAR) T-cell therapies have evolved as breakthrough treatment options for the management of hematological malignancies and are also being developed as therapeutics for solid tumors. However, despite the impressive patient responses from CD19-directed CAR T-cell therapies, ~ 40%-60% of these patients' cancers eventually relapse, with variable prognosis. Such relapses may occur due to a combination of molecular resistance mechanisms, including antigen loss or mutations, T-cell exhaustion, and progression of the immunosuppressive tumor microenvironment.

FSH mediates estradiol synthesis in hypoxic granulosa cells by activating glycolytic metabolism through the HIF-1α-AMPK-GLUT1 signaling pathway.

Owing to the avascular environment within ovarian follicles, granulosa cells (GCs) are believed to live in a hypoxic niche. Follicle-stimulating hormone (FSH)-mediated steroidogenesis is crucial for normal growth and maturation of ovarian follicles, but it remains unclear how FSH stimulates estradiol (E2) synthesis under hypoxic conditions. Here, we aimed to explore whether FSH affects the ATP production required for estrogen synthesis from the perspective of glucose metabolism.

Synthesis, characterization, DNA/BSA interactions and in vitro cytotoxicity study of palladium(II) complexes of hispolon derivatives.

Thirteen novel palladium(II) complexes of the general formula [Pd(bipy)(O,O'-dkt)](PF), (where bipy is 2,2'-bipyridine and O,O'-dkt is β-diketonate ligand hispolon or its derivative) have been prepared through a metal-ligand coordination method that involves spontaneous formation of the corresponding diketonate scaffold. The obtained palladium(II) complexes have been characterized by NMR spectroscopy, ESI-mass spectrometry as well as elemental analysis. The cytotoxicity analysis indicates that most of the obtained palladium(II) complexes show promising growth inhibition in three human cancer cell lines.

Development of curcumin-loaded methoxy poly(ethylene glycol)-block- poly(caprolactone)-block-poly(1, 4, 8-Trioxa [4.6] spiro-9-undecanone) nanoparticles and studies on their in vitro anti-tumor activities.

The purpose of this paper was to fabricate a novel methoxy poly(ethylene glycol)-block-poly(caprolactone)-block-poly(1, 4, 8-Trioxa [4.6] spiro-9-undecanone) (mPEG-b-PCL-b-PTOSUO, mPECT) triblock copolymer and study on the in vitro anti-tumor activity of curcumin-loaded mPECT nanoparticles (NPs). The mPEG-b-PCL-b-PTOSUO NPs were fabricated with solvent evaporation.

Synthesis and activity of functionalizable derivatives of the serotonin (5-HT) 5-HT receptor (5-HTR) antagonist M100907.

The approach of tethering together two known receptor ligands, to be used as molecular probes for the study of G protein-coupled receptor (GPCR) systems, has proven to be a valuable approach. Selective ligands that possess functionality that can be used to link to other ligands, are useful in the development of novel antagonists and agonists. Such molecules can also be attached to reporter molecules, such as fluorophores, for the study of GPCR dimerization and its role in signaling.

Design of poly(mPEGMA-co-MAA) hydrogel-based mPEG-b-PCL nanoparticles for oral meloxicam delivery.

To enhance the therapeutic effects of meloxicam (MLX), we developed an oral MLX-loaded poly(ethylene glycol)-b-poly(ε-caprolactone) nanoparticles@hydrogel (MLX-NPs@hydrogel) preparation. The MLX-NPs were fabricated via a solvent evaporation method, and their morphologies were observed by a JEM-1011 transmission electron microscope (TEM). The poly(mPEGMA-co-MAA) hydrogels were synthesized, and studies on their pH sensibilities were carried out in pH1.

Adsorption performance of creatinine on dialdehyde nanofibrillated cellulose derived from potato residues.

Potato residue is vastly produced in the food industry but it is landfilled. This article describes the treatment of purified cellulose derived from potato residues by a high pressure homogenizer to produce nano-fibrillated cellulose (NFC), which was then oxidized by sodium periodate to prepare dialdehyde nano-fibrillated cellulose (DANFC). The produced NFC and DANFC were characterized by a scanning electron microscope (SEM) and Fourier transform infrared spectroscopy (FTIR).
