Flavonoids, the major polyphenol components in Cotinus coggygria (CC), have been found to show an anticancer effect in our previous study; however, the exact mechanisms of inducing human glioblastoma (GBM) cell death remain to be resolved. In this study, a novel polyvinylpyrrolidone K-30/sodium dodecyl sulfate and polyethyleneglycol-coated liposome loaded with CC flavonoids (CCFs) was developed...

Before the metabolic role of the blood plasma expander, polyvinylpyrrolidone (PVP) can be studied by the technic of ionography, some fundamental ionographic characteristics of the polymer, per se, must be determined. This study is concerned with the influence of such variable factors as time, potential gradient, temperature, the pH of the buffer and its ionic strength on the mobility of the mig...

The silver nanoparticles (AgNPs) have been applied as an antibacterial agent in consumer products, cosmetics, and food industries. In this present work, AgNPs were synthesized various mediums of polyvinylpyrrolidone (PVP), polyethylene glycol (PEG), chitosan using the pulse laser ablation synthesis method. Experimentally, a Nd:YAG beam (1064 nm, 7 ns, 30 mJ) was directed mirror focused quartz l...

Drop-on-demand (DOD) bioprinting has attracted huge attention for numerous biological applications due to its precise control over material volume and deposition pattern in a contactless printing approach. 3D bioprinting is still an emerging field and more work is required to improve the viability and homogeneity of printed cells during the printing process. Here, a general purpose bio-ink was ...

We addressed the question to which extent cerebral blood flow (CBF) is maintained when, in addition to a high blood viscosity (Bvis) arterial oxygen content (CaO2) is gradually decreased. CaO2) was decreased by hemodilution to hematocrits (Hct) of 30, 22, 19, and 15% in two groups. One group received blood replacement (BR) only and served as the control. The second group received an additional ...
