Novel Isoxazole-Based Antifungal Drug Candidates.

Microbiological communities have a significant impact on health and disease. are ubiquitous fungal pathogens that colonize the mucosal surfaces of the genital, urinary, respiratory, and gastrointestinal tracts, as well as the oral cavity. If the immune system is inadequate, then infections may pose a significant threat.

Oxidation of myrtenol to myrtenal epoxide in a porphyrin-based photocatalytic system - A novel terpene alcohol derivative with antimicrobial and anticancer properties.

Biomimetic catalysis using porphyrins enables gentle oxidation of terpenes with molecular oxygen and light. This study explores the photooxidation of (-)-myrtenol under visible light to synthesize new terpenoid products with promising biological activity. Among the porphyrins tested, tetraphenylporphyrin (HTPP) exhibited the highest catalytic efficiency and stability in chloroform, producing myrtenal epoxide (ME) as the main product (with a molar conversion of myrtenol of 66.

In Vitro and In Vivo Translational Insights into the Intraoperative Use of Antiseptics and Lavage Solutions Against Microorganisms Causing Orthopedic Infections.

The growing antibiotic resistance of microorganisms causing postoperative infections following orthopedic surgeries underscores the urgent need for localized antiseptic and lavage delivery systems to enhance infection control. This study evaluates the in vitro effectiveness of antiseptic and lavage solutions-including polyhexanide, povidone-iodine, low-concentrated hypochlorite, Ringer's solution, and saline-against , MRSA, , , , and . Using microplate models (Minimum Inhibitory Concentration, Minimum Biofilm Eradication Concentration, and Biofilm-Oriented Antiseptic Test assays), flow-based models (Bioflux system), and surfaces relevant to orthopedic implants (e.

New Biocompatible Ti-MOF@hydroxyapatite Composite Boosted with Gentamicin for Postoperative Infection Control.

The standard clinical management of osteomyelitis involves prolonged antibiotic therapy, which frequently necessitates the excision of infected tissues. However, the efficacy of such treatments is increasingly compromised by the rise of antibiotic-resistant pathogens, underscoring an urgent need for innovative approaches. This study introduces a novel composite material designed to offer dual functionality: robust antimicrobial activity and promotion of bone regeneration.

Galleria mellonella larvae as a model for Helicobacter pylori biofilm formation under antibiotic stress.

Helicobacter pylori is a common Gram-negative bacterium that inhabits the human stomach and causes a variety of gastric pathologies. One of the growing concerns is its dynamic spread of antibiotic resistance, a process in which biofilm formation is involved. Therefore, it is necessary to find an appropriate, high-throughput research model for the in vivo biofilm development by H.
