Multifunctional Bioactivity Electrospinning Nanofibers Encapsulating Emodin Provide a Potential Postoperative Management Strategy for Skin Cancer.

Skin cancer is threatening more and more people's health; its postoperative recurrence and wound infection are still critical challenges. Therefore, specialty wound dressings with multifunctional bioactivity are urgently desired. Emodin is a natural anthraquinone compound that has anti-cancer and anti-bacterial properties.

Effect of solvents on the chiral recognition mechanisms of immobilized cellulose-based chiral stationary phase.

The effect of solvents on the enantioselectivities of four structurally similar chiral solutes with a cellulose derivative-based chiral stationary phase, Chiralpak IB, were studied using acetone (AC), 2-propanol (IPA), and tert-butanol (TBA) separately as polar modifiers. The enantioselectivities α of benzoin and methyl mandelate decrease with an increase in modifier concentration C, whereas the enantioselectivity of pantolactone increased with increasing AC concentration. These results were attributed to the heterogeneous adsorption mechanisms of enantiomers.

Long-Term Effect against Methicillin-Resistant of Emodin Released from Coaxial Electrospinning Nanofiber Membranes with a Biphasic Profile.

Methicillin-resistant (MRSA) is a serious and rapidly growing threat to human beings. Emodin has a potent activity against MRSA; however, its usage is limited due to high hydrophobicity and low oral bioavailability. Thus, the coaxial electrospinning nanofibers encapsulating emodin in the core of hydrophilic poly (vinylpyrrolidone), with a hygroscopic cellulose acetate sheath, have been fabricated to provide long-term effect against MRSA.

Comprehensive analysis of the compound profiles of Folium Camelliae Nitidissimae extract by ultrafast liquid chromatography with quadrupole-time-of-flight mass spectrometry and hepatoprotective effect against CCl -induced liver injury in mice.

Folium Camelliae Nitidissimae (jinhuacha in Chinese, JHC) is a kind of caffeine-less tea with antioxidant, antitumor and antibacterial effects. Studies on the chemical profiles and hepatoprotective effects of JHC extracts have not been systematically conducted so far. This study comprehensively investigated the compound profiles of JHC extract by ultrafast liquid chromatography with quadrupole time-of-flight tandem mass spectrometry.
