Polyacrylamide gel (PAAG) has been used as a soft tissue filler material for cosmetic purposes in Europe and China since 1997. The various complications of PAAG have been reported. A total of 15 patients who received PAAG injections at other institutions were treated for gel migration in the authors' hospitals. During treatment, the authors found that the injected PAAG had not formed capsules within the muscle and was encapsulated only by thin fibrous tissue in skin and mammary glands. Consequently, the filler material migrated easily because of muscular activity or the influence of gravity, especially when the capsule was broken by incorrect massage or incidental force. It is suggested that PAAG should not be injected into muscular tissue or subcutaneous areas with active movement, such as joints and muscles involved in facial expression with thin skin. After years of gel implantation, the thinned capsule may result in an increasing incidence of this complication. Management and some clinical findings in relation to the complication also are discussed.

: This study aimed to design and evaluate Chol-PEG micelles and Chol-PEG vesicles as drug delivery system (DDS) carriers and inhibitors of amyloid-β (Aβ) aggregation, a key factor in Alzheimer's disease (AD). : The physical properties of Chol-PEG assemblies were characterized using dynamic light scattering (DLS), electrophoretic light scattering (ELS), and transmission electron microscopy (TEM). Inhibitory effects on Aβ aggregation were assessed via thioflavin T (ThT) assay, circular dichroism (CD) spectroscopy, and native polyacrylamide gel electrophoresis (native-PAGE).

In recent years, conductive gel materials have attracted extensive attention in the field of flexible electronics because of their excellent elasticity. When constructed as gel fibers, they can adapt to greater deformation, be woven, and be assembled with fabrics to make wearable smart devices without compromising comfort. However, gel fibers reported often exhibit insufficient mechanical properties and poor adaptability to different environment.

A polyacrylamide gel method has been used to synthesize a variety of polyvalent-transition-metal-doped Ni position of high entropy spinel oxides (NiZnMgCuCo)AlO-800 °C (A) on the basis of NiAlO, and the catalytic activity of A is studied under the synergistic action of peroxymonosulfate (PMS) activation and simulated sunlight. The A containing polyvalent transition metals (Ni, Cu, and Co) can effectively activate PMS and efficiently degrade levofloxacin (LEV) and tetracycline hydrochloride (TCH) under simulated sunlight irradiation. After 90 min of light exposure, the degradation percentages of LEV (50 mg L) and TCH (100 mg L) degrade by the A/PMS/vis system reach 87.
