Electrophoretic Deposition of Gentamicin Into Titania Nanotubes Prevents Evidence of Infection in a Mouse Model of Periprosthetic Joint Infection.

Periprosthetic joint infection (PJI) is a leading cause and major complication of joint replacement failure. As opposed to standard-of-care systemic antibiotic prophylaxis for PJI, we developed and tested titanium femoral intramedullary implants with titania nanotubes (TNTs) coated with the antibiotic gentamicin and slow-release agent chitosan through electrophoretic deposition (EPD) in a mouse model of PJI. We hypothesized that these implants would enable local gentamicin delivery to the implant surface and surgical site, effectively preventing bacterial colonization.

Morphological variations and adhesive distribution: a cross-species examination in conidia.

is a globally significant genus of plant pathogens known for causing anthracnose across a diverse array of hosts. Notably, is a pathogen affecting maize. Annually, the global economic impact of this pathogen reaches billions of US dollars.

Constructing Dynamical Symmetries for Quantum Computing: Applications to Coherent Dynamics in Coupled Quantum Dots.

Dynamical symmetries, time-dependent operators that almost commute with the Hamiltonian, extend the role of ordinary symmetries. Motivated by progress in quantum technologies, we illustrate a practical algebraic approach to computing such time-dependent operators. Explicitly we expand them as a linear combination of time-independent operators with time-dependent coefficients.
