Preparation and characterization of PEG-Dex macromolecular schiff base particles and their application on the stabilization of water-in-water emulsion.

In this study, polyethylene glycol (PEG) and dextran (Dex) were chemically modified to obtain amino-functionalized PEG (PEG-(NH)) and oxidized dextran (ODex). They were subsequently reacted via -NH and -CHO groups to synthesize a macromolecular Schiff base particle. The structures, morphologies, and thermal properties of the macromolecular Schiff base particle were characterized using Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and thermogravimetry analysis (TGA).

Silent circulation of plasmid-borne tet(X6) and bla genes in a community-acquired Acinetobacter baumannii strain.

To characterize the genomic features of a community-acquired Acinetobacter baumannii strain, co-carrying tet(X6) and bla genes, but was susceptible to tigecycline and carbapenems. The tet(X6) and bla genes were found on a 149,518 bp non-conjugative plasmid. The bla gene was silent, due to the presence of an intact ISAba3-like element upstream, which rendered the strain susceptible to carbapenems.

Blue light promotes conjunctival epithelial-mesenchymal transition and collagen deposition through ITGB4.

The increasing prevalence of LED technology heightened blue light (BL) exposure, raising concerns about its long-term effects on ocular health. This study investigated the transcriptomic response of conjunctiva to BL exposure, highlighting potential biomarkers for conjunctival injury. We exposed human conjunctival epithelial cells and C57BL/6 mice to BL to establish in vitro and in vivo models and identified the responsive genes in mice's conjunctiva to BL exposure by RNA sequencing transcriptome analysis.

Primary hepatic epithelioid hemangioendothelioma: a case report.

Epithelioid hemangioendothelioma is a low-grade malignant tumor of vascular origin. The rarity of hepatic epithelioid hemangioendothelioma (HEHE) makes the diagnosis and treatment of this entity challenging. We report a case of a 69-year-old female patient who suffered from HEHE and complained of abdominal distension pain with dizziness and appetite loss for more than half a month.

Highly Efficient Analysis on Biomass Carbohydrate Mixtures by DREAMTIME NMR Spectroscopy.

Proton (H) NMR spectroscopy presents a powerful tool for biomass mixture studies by revealing the involved chemical compounds with identified ingredients and molecular structures. However, conventional H NMR generally suffers from spectral congestion when measuring biomass mixtures, particularly biomass carbohydrate samples, that contain various physically and chemically similar compounds. In this study, a targeted detection NMR approach, DREAMTIME, is exploited for studying biomass carbohydrate mixtures by spectroscopically targeting the desired compounds in separate 1D NMR spectra.
