Cytotoxicity and Bonding Property of Bioinspired Nacre-like Ceramic-Polymer Composites.
Front Bioeng Biotechnol
May 2022
For clinical applications, non-cytotoxicity and good bonding property of dental restorative materials are the most essential and important. The aim of this study was to evaluate the potential for clinical applications of two novel bioinspired nacre-like ceramic (yttria-stabilized zirconia)-polymer (polymethyl methacrylate) composites in terms of the cytotoxicity and bonding property. The relative growth rates (24 h) of the Lamellar and Brick-and-mortar composites measured by CCK8 were 102.

However, the underlying mechanisms by which uniconazole regulates drought response remain largely unknown. Here, the effects of exogenous uniconazole on drought tolerance in hemp were studied via physiological and transcriptome analyses of the drought-sensitive industrial hemp cultivar Hanma No.

The toxicity, removal rate, adsorption process and accumulation of Mo were investigated in the short-term indoor-culture experiment. The effects of Mo adsorbed by two plants in nutrition solution with different concentrations were also studied.

Water Sci Technol
January 2011
Pollution from nonpoint-source (NPS) nitrogen (N) and phosphorus (P) are the main causes of eutrophication in lotic, lentic and coastal systems. The climate of cold regions might play an important role in disturbing environmental behavior of NPS N and P, influencing simulation of watershed scale hydrologic and nonpoint-source pollution models. The losses of NPS N and P increase in regions of cold climate.

- Oxytetracycline (OTC) and zinc (Zn2+) are commonly used as growth promoters in animal agriculture and can impact soil systems through manure application, highlighting the need to study their environmental interactions.
- The study found that OTC is absorbed more strongly by montmorillonite clay compared to kaolinite due to montmorillonite's higher cation exchange capacity, with different pH levels affecting the sorption patterns of both substances.
- The presence of Zn2+ influenced OTC sorption in various pH conditions, showing competition at lower pH levels, while complexation between OTC and Zn2+ was observed to potentially occur at higher pH values, particularly around pH 6.5.
