PCL/Locust bean gum nanofibers loaded with HP-β-CD/Epicatechin clathrate compounds for fruit packaging.

In this work, the hydroxypropyl-β-cyclodextrin (HP-β-CD)/Epicatechin (EC) clathrate compounds were rapidly prepared based on an ultrasound-mediated method, and Polycaprolactone (PCL)/Locust bean gum (LBG) nanofibers loaded clathrate compounds were fabricated by electrostatic spinning (ELS) for fruit packaging. The results of infrared spectrum and crystal type analysis proved that clathrate compounds were successfully prepared. With the addition of clathrate compounds, the diameter of fibers increased from 553.

PCL/Yam Polysaccharide nanofibrous membranes loaded with self-assembled HP-β-CD/ECG inclusion complexes for food packaging.

In this study, Polycaprolactone (PCL)/Yam Polysaccharide (YP) fiber membranes loaded the ultrasound-mediated assembly of 2-Hydroxypropyl-β-cyclodextrin (HP-β-CD)/Epicatechin gallate (ECG) inclusion complexes were prepared by electrospinning technology for food packaging. Morphology, infrared spectroscopy and X-ray diffraction results showed that the inclusion complexes were successfully assembled. With the addition of inclusion complexes, the average diameter of the fibers increased from 2480.

Development of a fluorescent probe based on a tricyano structure for the detection of PhSH in environmental and biological samples.

In this study, a NIR fluorescent probe based on ICT principles was developed for the detection of phenylthiophenol. An excellent fluorescent mother nucleus is constructed with tricyano groups, and benzenesulfonate was introduced as a specific recognition site for thiophene, which can be used for rapid detection of thiophenol. The probe has a significant Stokes shift (220 nm).

Dicyanisophorone-based near-infrared fluorescent probe for the detection of thiophenol and its application in living cells and actual water samples.

This article reports a new type of dicyanisophorone-based near-infrared fluorescent probe for the rapid detection of mercaptophenol by introducing 2,4-dinitrobenzene sulfonate group as a specific recognition group for thiophenol. The probe has a significant large Stokes shift (185 nm). At the same time, it exhibits rapid response, high selectivity and high sensitivity to thiophene.

A ratiometric and colorimetric fluorescent probe designed based on FRET for detecting SO/HSO in living cells and mice.

Based on the principle of FRET, we have developed a ratiometric and colorimetric fluorescent probe TFBN, which can specifically recognize SO derivatives (SO/HSO), and exhibit a transition from red to green fluorescence under 405 nm excitation. The probe TFBN owns the advantages of short response time (<3 min), quantitative detection SO derivatives in two linear ranges, extremely low detection limit (39 nM), large Stokes shift (239 nm) and wide emission window gap (140 nm). In addition, the NBC structure was used as a fluorescent donor for FRET probes for the first time, which expanded the diversity of donors.

[Application of emergency hysterectomy on severe postpartum hemorrhage].

Objective: To investigate the value of emergency hysterectomy on arresting severe postpartum hemorrhage.

Methods: A retrospective analysis was performed on 10 cases of hysterectomy by reason of postpartum hemorrhage between Jan 1990 and Dec 2000.

Results: All the patients were severe postpartum hemorrhage that couldn't be controlled by conservative treatment.
