Fluorescent probe

Detection of nitroaromatic explosives (NAEs) is very important in terms of national security as well as the damage they cause to living things and the environment. The precision detection of these is a very important issue to reduce their harmful effects and take the necessary precautions. Electron-rich polyaromatic fluorescent materials are highly sensitive and selective in the detection of NAEs in terms of their fluorometric quenching abilities.

Mussels of the genus Mytilus present morphologically similar karyotypes that are presumably conserved. The absence of chromosome painting probes in bivalves makes difficult verifying this hypothesis. In this context, we comparatively mapped ribosomal RNA and histone gene families on the chromosomes of Mytilus edulis, M. galloprovincialis, M. trossulus and M. californianus by fluorescent in situ hybridization (FISH).

The purpose of the study is to investigate the function of TRPV4 on ferroptosis in ALI mice induced by lipopolysaccharide (LPS). In vitro, the regulation of TRPV4 on Ca2+ and ferroptosis was detected by CCK-8, fluorescent probe, and western blot in BEAS-2B cells. In vivo, the role of TRPV4 antagonists on ALI mice was analyzed by determination of pulmonary inflammation, pulmonary edema, and ferroptosis.

Porcine epidemic diarrhea virus (PEDV), an intestinal coronavirus that causes acute diarrhea and high mortality in suckling piglets, can result in high economic losses in the swine industry. In recent years, despite the use of China’s current vaccine immunization strategy, multiple types of PEDV strains were still found in immunized swine herds.

The three-dimensional (3D) organization of chromosomes can be probed using methods like Capture-C. However, it is unclear how such population-level data relate to the organization within a single cell, and the mechanisms leading to the observed interactions are still largely obscure. We present a polymer modeling scheme based on the assumption that chromosome architecture is maintained by protein bridges, which form chromatin loops.

A rhodamine B derivative containing 1,2,4-triazole as subunit was characterized as an “off–on” type Cu2+ - selective fluorescent probe. It exhibited high selectivity and sensitivity for Cu2+ in ethanol–water solution (9:1, v:v, pH 7.0, 20 mM HEPES) and underwent ring opening. A prominent fluorescence enhancement at 570 nm was observed in the presence of Cu2+ with the change in the absorption spectrum, and a 1:1 metal–ligand complex was formed.

This probe showed good selectivity towards Al 3+ compared to other common ions. Under optimized experimental conditions, the probe exhibited a linear dynamic response for Al 3+ from 5.0 × 10−7 to 4.5 × 10−6 M with a detection limit of 1.3 × 10−7 M in ethanol–water solution (9:1, v:v, pH 6.8, 20 mM HEPES). Furthermore, it was used for imaging of Al3+ in living cells with satisfying results.

A general synthetic method was improved to synthesize a chemosensor based on a tripodal Bodipy (t-BODIPY) structure. The product and its intermediate products were successfully prepared and fully characterized. The metal ion sensing performance of the tripodal compound was evaluated by UV/Vis and fluorescence spectroscopies. According to the obtained data, t-BODIPY is a selective and sensitive fluorescence probe for detection of Cu2+ ions in the presence and in the absence of competing ions. This chemosensor presents relatively a low detection limit of 5.4 x10–7 M for Cu2+.

In this study, a novel spectrofluorometric assay based on p-cresol (4-methyl phenol) probe is developed for the measurement of HOBr scavenging activity. It is the first study involving the use of a p-cresol probe for the determination of the HOBr scavenging activity of biothiols. While the p-cresol probe (λex = 260 nm, λem = 305 nm) has fluorescence characteristics, its brominated derivatives emerging at the end of the oxidation reaction with HOBr do not show fluorescence.
