Treatment of paediatric burns with a nanocrystalline silver dressing compared with standard wound care in a burns unit: A cost analysis

Burns are a leading cause of non-natural death in South African infants and children. Conventional care of partial-thickness burns often requires painful, time consuming and costly twice-daily dressing changes to clean the wound and apply antimicrobial topical agents. A new topical nanocrystalline silver-coated (NS) dressing (Acticoat; Smith & Nephew) has been developed and is the first-line treatment of choice in many burn centres. However, because of its cost the Department of Health has been reluctant to introduce it as a standard of care. We retrospectively studied 4 randomly selected paediatric burn patients, calculating the cost associated with the use of NS dressings and comparing this with the projected costs of three previously standard burn wound treatment regimens. NS dressings were changed every 3 days based on their sustained and slow release of silver ions over 72 hours. Using NS clearly saved costs compared with the three other regimens. The demonstrated cost savings resulted primarily from the decreased number of dressings, and the presumed shorter hospital stay

Interlayer configurations of self-assembled folded graphene

The relative orientation between atomic lattices in twisted bilayer graphene opens up a whole new field of rich physics. So, the study of self-assembled twisted bilayer graphene gives deep insight into its underlying growth process. Cuts in monolayer graphene via the atomic force microscopy technique are used to start self-assembly and to generate a folding process. The final configurations for this self-assembly process are investigated. Here, the focus is on structures that arise from one cut. During the self-assembly, these structures not only move forward but also rotate. As it turns out, the final positions for all studied structures can be assigned to commensurate interlayer configurations

Chief\u27, a very tall Maturity Group IV variety, was used as a donor parent in backcrossing to \u27Clark\u27 to transfer Np (a gene for high phosphorus tolerance). In the field in 1963, I grew progenies from 40 selected Np F2 plants from Clark BC5 and was surprised to see 2 of the progenies uniformly very tall and 3 of them segregating approximately 1/4 tall plants. The Np gene appears to have no effect on field-grown plants in normal soils
