Converging frontiers in cancer treatment: the role of nanomaterials, mesenchymal stem cells, and microbial agents-challenges and limitations.

Globally, people widely recognize cancer as one of the most lethal diseases due to its high mortality rates and lack of effective treatment options. Ongoing research into cancer therapies remains a critical area of inquiry, holding significant social relevance. Currently used treatment, such as chemotherapy, radiation, or surgery, often suffers from other problems like damaging side effects, inaccuracy, and the lack of ability to clear tumors.

Enhancing the Antibacterial Impact of Lipopeptide Extracted from as a Probiotic against MDR .

Background: The antibiotic resistance of microorganisms is escalating rapidly. Infections caused by opportunistic pathogens in immunocompromised individuals have prompted researchers to seek for potent and safe antibacterial agents. The purpose of this investigation was to explore the suppression of virulence gene expression, specifically the operon genes responsible in biofilm formation in , through the utilization of metabolites obtained from probiotic bacteria.

Introducing of high rich lysine, arginine, and unsaturated fatty acids microalga as a food supplement.

Microalgae are powerful source for nutritionally valuable components as proteins, carbohydrates and especially unsaturated fatty acids. Microalgae may be employed in pharmaceutical, food, cosmetic, health industries, and biofuels. In this study for looking at high-level unsaturated fatty acids species, from 31 strains, by comparing growth curves, the best strain with a high growth rate and lipid content was selected by red Nile staining.

Effect of lipopeptide extracted from Bacillus licheniformis on the expression of bap and luxI genes in multi-drug-resistant Acinetobacter baumannii and Pseudomonas aeruginosa.

Recently, opportunistic pathogens like Acinetobacter baumannii and Pseudomonas aeruginosa have caused concern due to their ability to cause antibiotic resistance in weakened immune systems. As a result, researchers are always seeking efficient antimicrobial agents to tackle this issue. The hypothesis of the recent study was that probiotic products derived from bacteria would be effective in reducing drug resistance in other bacteria.

Exopolysaccharide-mediated silver nanoparticles synthesized from Lactobacillus paracasei with antimicrobial, antibiofilm and antioxidant activities.

Biofilm formation and resistance to antibiotics in pathogenic bacteria are important concerns in the treatment of infectious diseases. A new rapid, eco-friendly and cost-effective strategy to overcome these problems is the use of microbial exopolysaccharides (EPS) for green synthesis of various metal nanoparticles (NPs). This study used EPS from a native probiotic Lactobacillus isolate to synthesize silver nanoparticles (AgNPs) with effective antimicrobial, antibiofilm and antioxidant properties.

Investigation of diverse biosynthetic secondary metabolites gene clusters using genome mining of indigenous strains isolated from saline soils in Iran.

Background And Objectives: Bioactive secondary metabolites are the products of microbial communities adapting to environmental challenges, which have yet remained anonymous. As a result of demands in the pharmaceutical, agricultural, and food industries, microbial metabolites should be investigated. The most substantial sources of secondary metabolites are strains and are potential candidates for bioactive compound production.

Analysis of the A549 cell line affected by anticancer bioactive compounds of Actinomycetes isolated from saline soils.

Actinomycetes are filamentous bacteria and the residents of the soil, prone to produce bioactive metabolites. This research aimed to isolate, classify, and investigate the anticancer properties of Actinomycetes secondary metabolites from various saline soils of Qom province. Actinomycetes isolates were molecularly recognized by 16SrRNA gene sequencing after the PCR procedure.

Computational Design and Analysis of a Multi-epitope Against Influenza A virus.

Influenza A viruses are among the most studied viruses, however no effective prevention against influenza infection has been developed. So, designing an effective vaccine against Influenza A virus is a critical issue in the field of medical biotechnology. For this reason, to combat this disease, we have designed a novel multi-epitope vaccine candidate based on the several conserved and potential linear B-cell and T-cell binding epitopes by using the in silico approach.

Exploration, antifungal and antiaflatoxigenic activity of halophilic bacteria communities from saline soils of Howze-Soltan playa in Iran.

In the present study, halophilic bacteria communities were explored in saline soils of Howze-Soltan playa in Iran with special attention to their biological activity against an aflatoxigenic Aspergillus parasiticus NRRL 2999. Halophilic bacteria were isolated from a total of 20 saline soils using specific culture media and identified by 16S rRNA sequencing in neighbor-joining tree analysis. Antifungal and antiaflatoxigenic activities of the bacteria were screened by a nor-mutant A.
