Metanephric stromal tumor in an adult with PDGFRA mutation: a case report.

Background: Metanephric stromal tumors (MST) are rare benign renal tumors that mainly occur in infants and children. Approximately 72% of MST in children have the B-Raf proto-oncogene serine/threonine kinase (BRAF) V600E mutation. To date, only five cases of adult MSTs have been reported and no clear genetic alterations have been found.

MF59 adjuvant enhances the immunogenicity and protective immunity of the OmpK/Omp22 fusion protein from Acineterbacter baumannii through intratracheal inoculation in mice.

Acinetobacter baumannii (A baumannii) is an emerging nosocomial pathogenic bacterium which leads to hospital infections. The increase in drug-resistant A baumannii strains makes it difficult to control by using common antibiotics. The development of effective vaccines is an alternative means to avoid A baumannii infections.
