The rationale and potential for using Lactobacillus in the management of periodontitis
Wang Jiaqi,Liu Yingman,Wang Weiru,Ma Jiaojiao,Zhang Manman,Lu Xiaoying,Liu Jie,Kou Yurong 한국미생물학회 2022 The journal of microbiology Vol.60 No.4
Periodontitis refers to a wide range of the inflammatory conditions of supporting dental structures. For some patients with periodontitis, antibacterial agents are needed as an adjuvant to mechanical debridement treatments and oral hygiene maintenance. However, the widespread use of broad-spectrum antibiotics for the prophylaxis and treatment of periodontal infections results in the emergence of resistant pathogens. Therefore, probiotics have become markedly interesting to researchers as a potentially safe alternative to periodontal treatment and maintenance. Probiotics have been used in medicine for decades and extensively applied to the treatment of inflammatory diseases through the modulation of microbial synergy and other mechanisms. A growing amount of evidence has shown that using Lactobacillus strains for oral cavity maintenance could improve periodontal health. In this study, we reviewed studies showing proof of the inhibitory effects of Lactobacillus species on periodontal inflammation. We also explored the rationale and potential for using Lactobacillus species in the management of periodontitis.

A Novel Natural Dye Derivative for Natural Fabric Supercritical Carbon Dioxide Dyeing Technology
Jinsong Wu,Hongjuan Zhao,Mingyue Wang,Weiru Zhi,Xiaoqing Xiong,Laijiu Zheng 한국섬유공학회 2019 Fibers and polymers Vol.20 No.11
The supercritical carbon dioxide (SC-CO2) dyeing technology is a green dyeing technology, and the usage ofnatural dye makes SC-CO2 dyeing technology safer and more environment-friendly. Nevertheless, after using natural dye inSC-CO2 dyeing, the color depth and fastness of dyed natural fabric are poor. In this study, alkyl and hydroxyalkyl groupswere grafted onto alizarin, which is a natural dye, to elevate the color depths and fastness of alizarin-derivative-dyed naturalfabric. The results demonstrate that the color depths of alkyl-alizarin-dyed and hydroxyalkyl-alizarin-dyed natural fabricswere increased. This has to do with the increase in the solubilities of alkyl alizarin and hydroxyalkyl alizarin in SC-CO2. Thehydroxybutyl-alizarin-dyed wool displayed the best color depth (K/S value: 6.44). And the hydroxyalkyl-alizarin-dyednatural fabric showed good washing fastness and rubbing fastness (about 4-5 level), because that hydroxyalkyl alizarin couldbe linked by a covalent bond to the natural fabric.
