Electro-Fluidic Displays (EFD) have been demonstrated to be an attractive technology for incorporation into portable display devices. EFDs have excellent optical efficiency and fast switching enabling video content. Ensuring mechanical stability of EFD display cells is a key challenge and essential for developing large area as well as flexible displays. Although the electro-optic performance of...

Introduction. HyStem-C™ is a commercially available injectable hydrogel composed of polyethylene glycol diacrylate (PEGDA), hyaluronan (HA), and gelatin (Gn). These components can be mechanically tuned to enhance cell viability and spreading. Methods. The concentration of PEGDA with an added disulfide bond (PEGSSDA) was varied from 0.5 to 8.0% (w/v) to determine the optimal concentration for in...

Regenerative medicine is increasingly important in clinical practice. Ligamentum flava (LF) are typically removed during spine-related surgeries. LF may be a source of cells for spinal fusion that is conducted using tissue engineering techniques. In this investigation, LF cells of rabbits were isolated and then characterized by flow cytometry, morphological observation, and immunofluorescence s...

Cholinesterases are efficient scavengers of organophosphates and are currently being developed as drugs for treatment against poisoning by such compounds. Recombinant ChE bioscavengers have very short circular longevity, a limitation that can be overcome by complex post-translation manipulations or by chemical modification such as polyethylene glycol conjugation. Series of multiple Lys-Ala muta...

Although low concentrations of polyethylene glycol (1-5%, w/v) are essential for growing crystals of phosphoglucomutase from ammonium sulfate solutions (at close to 50% of saturation), the observed rate constant for short-term crystal growth on a defined, microcrystalline surface is essentially independent of polyethylene glycol concentration under these conditions. But this cosolute produces a...

Essential oils (EOs) are technological options that may be employed in natural foods due to their antimicrobial activities. However, restrictions exist when high EOs concentrations are required which, in their turn, affect sensory qualities. Technological alternatives, such as combination of EOs with chelating and dispersing agents, have been proposed in the literature. Current research determi...

Stevia rebaudiana is a sweet herb of the Astraceae family, which is cultivated for the natural sweeteners it contains. The aim of this study was to assess the effect of drought, simulated by the application of polyethylene glycol (5%, 10%, and 15% w/v), on the content of steviol glycosides (SVglys) and transcription levels of six genes involved in the biosynthesis of these natural sweeteners. T...

Experimental solubilities of acetaminophen and ibuprofen in polyethylene glycol 600-water, ethanol-polyethylene glycol 600, and polyethylene glycol 600-water-ethanol mixtures at 25 degrees Celsius are reported. The solubilities of drugs in the presence of ethanol and polyethylene glycol 600 were increased. The Jouyban-Acree model was used to fit the solubility data of each drug in the binary mi...

Systematic advancements in the field of musculoskeletal tissue engineering require clear communication about the mechanical environments that promote functional tissue growth. To support the rapid discovery of effective mechanostimulation protocols, this study developed and validated a mechanoactive transduction and evaluation bioreactor (MATE). The MATE provides independent and consistent mech...
