Introduction: This systematic review aimed to summarize the currently available evidence on the effect of oral probiotic therapy on infected wound healing among patients who underwent surgery.

Materials and methods: An electronic search was conducted for articles published during 2010- 2022 in Embase, PubMed/Medline, Scopus, Web of Science, and Google Scholar using the keywords "probiotics," "prebiotics," "synbiotics," and "wound infection." The titles and abstracts of 2625 articles were screened, and 22 publications that fulfilled the inclusion criteria were included.

Results: The current review provides evidence of the beneficial effects of probiotics on wound infection, significantly reducing the duration of antibiotic usage and the length of hospital stay for patients, with no serious side effects reported. Wound infections following various surgeries, such as abdominal wound surgery, colorectal cancer resection, periampullary neoplasms treatment, liver and bile duct resection, pancreaticoduodenectomy, esophagostomy, dental wound surgery, plastic surgery, and burns, are shown to be positively affected by probiotic usage. Although, in some cases, the improvements were not statistically significant, overall, the administration of probiotics appears to be satisfactory in this regard.

Conclusion: Probiotics demonstrate the ability to prevent the growth of pathogens and maintain wound space sterility by recruiting M2 macrophages, which produce anti-inflammatory markers and enhance the activity of phagocytic cells. Additionally, probiotics can reduce bacterial translocation from their niche to other areas and inhibit the production of bacterial mediators that lead to bacterial invasion.

Various substances possessing radiation scavenging properties, known as radioprotectors, play a crucial role in shielding organisms from the harmful effects of ionizing radiation (IR) by preventing cellular damage caused by free radicals. Initially, synthetic radioprotectors were developed using thiol synthetic compounds. However, among these, only amifostine (WR-2721) underwent clinical testing as a radioprotector. Various composites with different chemical structures other than thiol compounds were also investigated. However, synthetic radioprotectors are known to be associated with severe side effects, which lead to an inclination towards natural substances. Plants and natural products have emerged as promising sources of radioprotectors, renowned for their non-toxic nature across a broad range of doses and their cost-effectiveness. Radioprotectors are employed in diverse pharmaceutical approaches to mitigate the toxicities induced by radiation. The present review encompasses a detailed account of various synthetic and naturally occurring compounds possessing radioprotective properties, and different investigations related to their radioprotective action, ranging from free radicals scavenging to gene therapy, have also been precisely covered. Numerous radioprotectors have different mechanisms of action, and have proven benefits of naturally occurring compounds over chemically synthesized ones.

The utilization of In-silico subtractive genomic analysis has emerged as an important and essential method in modern drug discovery and development since it significantly improves the process of identifying and validating potential targets for discovering novel therapeutic compounds to treat severe infections caused by Antimicrobial-resistant (AMR) - pathogenic species. This review provides a complete overview of the methodology, advantages, disadvantages, and prospects, associated with subtractive genomic research in the context of drug discovery and development. The initial phase of analysis encompasses the retrieval of data, which serves as a foundation for the subsequent data mining process in Phase 1. After data mining, Phase 2 utilizes subtractive channels for the target's non-homology and essentiality analysis. Phase 3 of the study aims to provide a comprehensive understanding of prospective targets by their qualitative characterization. Further, Phase 4 of the study emphasizes on conducting structure-based analyses, which involves the determination, refinement, evaluation, and validation of three-dimensional structures of the target proteins, along with their active site prediction and selection of the novel therapeutic compounds against that active site on the obtained targets through virtual screening and docking studies by utilizing various databases and servers. The therapeutic compounds obtained can be then validated by in vitro and in vivo testing, thereby establishing a connection between the computational predictions and real applications.

Nanotechnology has the potential to offer elegant solutions to problems experienced in the medical field, such as poor drug delivery efficiency and microbial resistance. In this sense, it is interesting to associate nanomaterials with substances that also offer desirable properties to favor human health. Green propolis is an example of a material that contains some of these useful substances. The phenolic acids present in this type of propolis have already been proven to present, for example, antimicrobial, immunostimulant, and antioxidant activities. In this minireview, recent nano solutions, presented through manuscripts have been recently published based on green propolis, receive attention due to their useful properties in the medical field. Limitations to the clinical use of nanomaterials and the future prospects are also addressed.

Background: Eliminating and managing L. monocytogenes, L. welshimeri, and L. ivanovii biofilms is a significant problem for food safety, as listeriosis is among the worst foodborne illnesses.

Method: The Listex P100 bacteriophage's bactericidal and inhibitory properties have been investigated in relation to varying strains of vegetative cells and biofilms of L. monocytogenes, L. welshimeri, and L. ivanovii.

Results: The phage concentrations of 109 and 1010 PFU/ml showed strong antibacterial activity against L. monocytogenes, L. welshimeri, and L. ivanovii at both 10°C and 30°C (P<0.05). In 96- well microplate experiments, bacteriophage treatment inhibited biofilm development and reduced biofilm by up to 57.6% (P ≤ 0.05). When compared to controls, Listex P100 bacteriophage significantly reduced the populations of L. monocytogenes, L. welshimeri, and L. ivanovii biofilms on the surfaces of galvanised, stainless steel, and plastic surfaces where holes were produced and the structure of Listeria spp. was disturbed.

Conclusion: This study clearly demonstrated that L. monocytogenes, L. welshimeri, and L. ivanovii biofilms on galvanised, stainless steel, and plastic surfaces might be removed by using Listex P100 bacteriophage.
