Misuse of antibiotics led to the world wide spread of antimicrobial resistance threatening human lives. The notable resistance of bacterial cells to antibiotics and immune system is the difficulty associated with biofilm-linked illnesses. Natural products from plant origin with antibiofilm activity could provide more therapeutic activity with fewer adverse effects. Carissa L. is a potential drug candidate that can be considered as an agro-food waste sustainable virulence inhibitor source. This mini-review sheds light on recent studies dealing with the anti-virulence potential of Carissa species and its different mechanisms of action. The traced articles revealed that Carissa species exhibited potent antibiofilm, anti-quorum sensing, hyaluronidase inhibitory and anti-adhesion potentials, in addition to violacein, and swimming motility inhibition activities. Ursolic acid, oleanolic acid, and methyl oleanate are the main phytoconstituents of Carissa with claimed virulence inhibitory potentials. Carissa species are safe, valuable, and effective anti-virulence drugs suppressing pathogenicity when compared to conventional antibiotics.

Soil-engaging components play a critical role in agricultural production and engineering construction. However, the soil-engaging components directly interacting with the soil often suffer from the problems of high resistance, adhesion, and wear, which significantly reduce the efficiency and quality of soil operations. A large number of featured studies on the design of soil-engaging components have been carried out while applying the principles of bionics extensively, and significant research results have been achieved. This review conducts a comprehensive literature survey on the application of biomimetics in the design of soil-engaging components. The focus is on performance optimization in regard to the following three aspects: draught reduction, anti-adhesion, and wear resistance. The mechanisms of various biomimetic soil-engaging components are systematically explained. Based on the literature analysis and biomimetic research, future trends in the development of biomimetic soil-engaging components are discussed from both the mechanism and application perspectives. This research is expected to provide new insights and inspiration for addressing related scientific and engineering challenges.

A flexor tendon injury is acquired fast and is common for athletes, construction workers, and military personnel among others, treated in the emergency department. However, the healing of injured flexor tendons is stretched over a long period of up to 12 weeks, therefore, remaining a significant clinical problem. Postoperative complications, arising after traditional tendon repair strategies, include adhesion and tendon scar tissue formation, insufficient mechanical strength for early active mobilization, and infections. Various researchers have tried to develop innovative strategies for developing a polymer-based construct that minimalizes these postoperative complications, yet none are routinely used in clinical practice. Understanding the role such constructs play in tendon repair should enable a more targeted approach. This review mainly describes the polymer-based constructs that show promising results in solving these complications, in the hope that one day these will be used as a routine practice in flexor tendon repair, increasing the well-being of the patients. In addition, the review also focuses on the incorporation of active compounds in these constructs, to provide an enhanced healing environment for the flexor tendon.
