Overcoming Antibiotic Resistance to Tetracycline in Staphylococcus aureus by Gold and Silver Nanoparticles - Cytology and Genetics

Abstract The use of tetracyclines in medicine, veterinary medicine, and stock raising has led to the spread of bacterial resistance to tetracycline, particularly among dangerous representatives of Staphylococcus aureus. Therefore, the analysis of resistance to tetracycline and the creation of approaches to overcome it are extremely relevant. Studies of 64 clinical isolates of S. aureus, which were characterized by moderate biofilm formation, showed that 33 of them contained plasmid DNA. A significant spread (in 96% of studied isolates) of the known transmissible tetracycline resistance genes tet(K) and tet(M) was shown in the examined plasmid-containing doxycycline-resistant clinical isolates of S. aureus. Plasmid-containing doxycycline-resistant clinical isolates with tet(K) and tet(M) genes lost resistance to the tetracycline antibiotic doxycycline after treatment of their cells with gold nanoparticles of 30 nm in a concentration of 3.2–9.6 μg/mL or medium-sized silver of 30 nm in a concentration of 20–40 μg/mL. Elimination of tet genes responsible for acquired resistance was confirmed by PCR.

Golden eyes see again. A retinal prosthesis with the potential to restore #vision lost or degraded vision due to age-related macular degeneration using gold #nanoparticles, which allows activation of cells in the eye using an infrared laser. Hope it'll work.
Naturally, the visual of it is got me just as interested as the medical implication. Think of the visuals for a Sci-Fi story, ho #writers - the old person with their eye reflecting in gold.

RNA interference and nanomedicine join forces to fight dangerous fungal infections

Fungal infections are on the rise globally. According to a study by the Manchester Fungal Infection Group, in 2022, approximately 6.5 million people were infected by a pathogenic fungus, and about 3.8 million died as a result—nearly twice as many as in 2012. Even with medications, known as antifungals, the mortality rate for invasive infections caused by the mold Aspergillus fumigatus is as high as 85%. As resistant fungal strains increase, treatment becomes more difficult, and new therapies are urgently needed.
