Radiolytic corrosion of actinide materials represent an issue for the long term storage and disposal of nuclear materials. Molecular species adsorbed at the surface of the actinides may impact the rate of radiolysis, and as the surfaces corrode, the soluble toxic and radioactive species leach into groundwater. It is therefore critical to characterise the surface composition of actinides. Here, we employ ab initio modelling to determine the surface composition of PuO2 with respect to adsorbed CO2. We found that CO2 interacts strongly with the surface forming carbonate species. By mapping the energetics of this interaction, we then calculate the temperature of desorption, finding that surface morphology has a strong impact on the adsorption of CO2, with the 100 being the most and the 111 the least affected by carbonation. Finally, we predict the effect of carbonation on the morphology of PuO2 nanoparticles as a function of temperature and pressure, finding that truncated octahedral is the preferred morphology. This modelling strategy helps characterise surface compensition and nanoparticle morphology, and we discuss the implication for radiolytically driven dispersal of material into the environment.The regeneration of periodontal tissue defects remains a clinical challenge due to its complex tissue structure (e.g. periodontal ligament, alveolar bone and cementum) and poor self-healing ability. In situ tissue engineering has emerged as a promising approach that combines frameworks with growth factors that are specifically chosen for the recruitment of endogenous stem cells to the site of injury and to evoke the innate regenerative potential of the body. Herein, a core/shell fibrous super-assembled framework (SAF)-based sequential growth factor delivery system is developed, in which basic fibroblast growth factor (bFGF) and bone morphogenetic protein-2 (BMP-2) are designed to release in a sequential manner to facilitate in situ regeneration of the cementum-ligament-bone complex. The in situ tissue engineering framework (iTE-framework) shows ameliorated physicochemical properties and improved hydrophilicity, with an initial burst release of bFGF in the first few days, followed by a slow and constant release of BMP-2 up to 4 weeks. The iTE-framework shows excellent biocompatibility, significantly promoting the proliferation, migration and osteogenic differentiation of human periodontal ligament stem cells (PDLSCs) in vitro. After implantation in rat periodontal defects, the iTE-framework effectively triggers the recruitment of mesenchymal stem cells (MSCs) to the defect site, significantly promotes the formation of new bones, and facilitates the regeneration of the periodontal ligament and cementum tissue in vivo. Therefore, this sequential delivery system provides a promising therapeutic strategy for cementum-ligament-bone complex regeneration.Sinus augmentation has been shown to be an effective methodology to augment a deficient maxillary sinus. However, there are many techniques a clinician can choose from. selleck chemical Historically, lateral window or crestal osteotome approaches were the most frequently discussed techniques. In this paper, a sinus floor elevation technique with crestal window sinus lift was proposed to treat cases of extremely atrophic maxillae (remaining bone height ≤ 2 mm). A crestal window is opened for the sinus membrane to be detached from the bony walls. After the proper elevation and membrane detachment, human particulated allografts were placed via the crestal access window to elevate the sinus membrane. Primary closure was then achieved, and after 6 to 9 months of healing, implant placement was performed. From the long-term clinical outcome that was obtained, the authors concluded that crestal window sinus lift is a procedure with predictable outcomes for lifting a maxillary sinus floor less than 2 mm thick, with an average elevation height of 11.73 mm.In the Amazon basin, indigenous forest-dwelling communities typically suffer from a high burden of infectious diseases, including malaria. Difficulties in accessing these isolated ethnic groups, such as the semi-nomadic Yanomami, make official malaria data largely underestimated. In the current study, we longitudinally surveyed microscopic and submicroscopic malaria infection in four Yanomami villages of the Marari community in the northern-most region of the Brazilian Amazon. Malaria parasite species-specific PCR-based detection of ribosomal and non-ribosomal targets showed that approximately 75% to 80% of all malaria infections were submicroscopic, with the ratio of submicroscopic to microscopic infection remaining stable over the 4-month follow-up period. Although the prevalence of malaria infection fluctuated over time, microscopically-detectable parasitemia was only found in children and adolescents, presumably reflecting their higher susceptibility to malaria infection. As well as temporal variation, thous populations in Latin America.The extent to which disturbances in the resident microbiota can compromise an animal's health is poorly understood. Hydra is one of the evolutionary oldest animals with naturally occurring tumors. Here, we found a causal relationship between an environmental spirochete (Turneriella spec.) and tumorigenesis in Hydra. Unexpectedly, virulence of this pathogen requires the presence of Pseudomonas spec., a member of Hydra´s beneficial microbiome indicating that dynamic interactions between a resident bacterium and a pathogen cause tumor formation. The observation points to the crucial role of commensal bacteria in maintaining tissue homeostasis and adds support to the view that microbial community interactions are essential for disease. These findings in an organism that shares deep evolutionary connections with all animals have implications for our understanding of cancer.Evolution of pest resistance reduces the efficacy of insecticidal proteins from the gram-positive bacterium Bacillus thuringiensis (Bt) used widely in sprays and transgenic crops. Better understanding of the genetic basis of resistance is needed to more effectively monitor, manage, and counter pest resistance to Bt toxins. Here we used CRISPR/Cas9 gene editing to clarify the genetics of Bt resistance and the associated effects on susceptibility to other microbial insecticides in one of the world's most damaging pests, the cotton bollworm (Helicoverpa armigera). We discovered that CRISPR-mediated knockouts of ATP-binding cassette (ABC) transporter genes HaABCC2 and HaABCC3 together caused >15,000-fold resistance to Bt toxin Cry1Ac, whereas knocking out either HaABCC2 or HaABCC3 alone had little or no effect. Inheritance of resistance was autosomal and recessive. Bioassays of progeny from interstrain crosses revealed that one wild type allele of either HaABCC2 or HaABCC3 is sufficient to sustain substantial susceptibility to Cry1Ac.
