Encouraging Specialty Certification: How Multilevel Support Can Help.

Professional development through specialty certification is positively associated with nurses' increased confidence in clinical skills, commitment to learning, empowerment, and professional credibility. This translates to improved patient outcomes, with higher organizational reimbursement, in addition to nurse retention and job satisfaction. Despite the call for lifelong learning from the Institute of Medicine, certification rates, especially among nurses in direct patient care, remain low.

Archaeal surface layer proteins contain beta propeller, PKD, and beta helix domains and are related to metazoan cell surface proteins.

The surface layer of archaeobacteria protects cells from extreme environments and, in Methanosarcina, may regulate cell adhesion. We identify three domain types that account for the complete architecture of numerous Methanosarcina surface layer proteins (SLPs). We solve the crystal structure for two of these domains, which correspond to the two N-terminal domains of an M.
