Bacterial infections are a common cause of clinical complications associated with the use of orthodontic microimplants. Biofilm formation on their surfaces and subsequent infection of peri-implant tissues can result in either exfoliation or surgical removal of these medical devices. In order to improve the properties of microimplants, hybrid coatings enriched with silver nanoparticles, calcium, and phosphorus were investigated.

State employee health plans are consuming an ever-larger portion of state budgets because of rising health insurance premiums. Often the largest purchaser of commercial health insurance in their state, state employee health plans possess a unique opportunity to implement cost containment strategies. This study estimated potential savings from hospital payment caps among state employee health plans and the impact on commercial hospital operating margins.

Background And Objective: Etiological diagnosis of community-acquired pneumonia (CAP) is only reached in 30-40% of cases, which frequently requires keeping empirical antibiotic regimens. The new nucleic acid amplification techniques (NAAT) in respiratory samples raise the possibility of improving this clinical practice. Our objective was to analyze TAANs contribution estimating both their costs and benefits.

Enzyme immobilization into carrier materials has broad importance in biotechnology, yet understanding the catalysis of enzymes bound to solid surfaces remains challenging. Here, we explore surface effects on the catalysis of sucrose phosphorylase through a fusion protein approach. We immobilize the enzyme via a structurally rigid α-helical linker [EAK] of tunable spacer length due to the variable number of pentapeptide repeats used ( = 6, 14, 19).

Source localization in EEG necessitates co-registering the EEG sensor locations with the subject's MRI, where EEG sensor locations are typically captured using electromagnetic tracking or 3D scanning of the subject's head with EEG cap, using commercially available 3D scanners. Both methods have drawbacks, where, electromagnetic tracking is slow and immobile, while 3D scanners are expensive. Photogrammetry offers a cost-effective alternative but requires multiple photos to sample the head, with good spatial sampling to adequately reconstruct the head surface.
