Antibiofilm Effects of Novel Compounds in Otitis Media Treatment: Systematic Review.

Otitis media (OM) is a frequent disease with incidence rate of 5300 cases per 100,000 people. Recent studies showed that polymicrobial biofilm formation represents a significant pathogenic mechanism in recurrent and chronic forms of OM. Biofilm enables bacteria to resist antibiotics that would typically be recommended in guidelines, contributing to the ineffectiveness of current antimicrobial strategies.

Redetermination of the crystal structure of RhPb from single-crystal X-ray diffraction data, revealing a rhodium deficiency.

RhPb (rhodium dilead) is a superconductor crystallizing in the CuAl structure type (space group 4/). The Rh and Pb atoms are located at the 4 (site symmetry 422) and 8 (.2) sites, respectively.
