The accumulation of potentially toxic elements (PTE) in a soil–rice system poses significant issue concern agricultural soils, particularly the polluted or high PTE geological background regions, such as karst areas. source identification, bioaccumulation factors PTE, and its health risk were investigated by correlation analysis, principal components single/comprehensive assessments soil-rice M...

Artificial metalloenzymes (ArMs) combine characteristics of both homogeneous catalysts and enzymes. Merging abiotic biotic features allows for the implementation new-to-nature reactions in living organisms. Here, we present directed evolution an artificial metalloenzyme based on Escherichia coli surface-displayed streptavidin (SavSD hereafter). Through binding a ruthenium-pianostool cofactor to...

BACKGROUND Bioterrorism using anthrax claimed five lives in the United States in 2001 and remains a potential public health threat. In the aftermath of a large-scale anthrax attack, mass screening to identify early inhalational anthrax may improve both the management of individual cases and the efficiency of health resource utilization. PURPOSE To develop the evidence base for outpatient anth...

BACKGROUND To know the epidemiology (prevalence, incidence, progression and morbidity and mortality associated) of peripheral artery disease in general population and the factors associated with this progression is essential to know the evolution of atherosclerosis and develop preventive strategies. The aim of the study was to determine the incidence of PAD after 5 years of follow-up population...

Gold electrodes were coated with alkanethiol SAM-azurin (Az, blue cupredoxin) assemblies and placed in contact with a water-doped and buffered protic ionic melt as the electrolyte, choline dihydrogen phosphate ([ch][dhp]). Fast-scan protein-film voltammetry was applied to explore interfacial biological electron transfer (ET) under conditions approaching the glass-transition border. The ET rate ...

BACKGROUND Better risk predictions for colorectal cancer (CRC) could improve prevention strategies by allowing clinicians to more accurately identify high-risk individuals. The National Cancer Institute's CRC risk calculator was created by Freedman et al using case control data. METHODS An online risk calculator was created using data from the Multi-Ethnic Cohort Study, which followed >180,00...

Background: Nitric oxide (NO), synthesised from the inducible isoform of nitric oxide synthase (iNOS), is implicated in mediating second window of protection (SWOP)/delayed ischemic preconditioning. However the role of NO and iNOS in delayed pharmacological protection remains unclear and is the subject of this investigation. Methods: To test the hypothesis that iNOS is necessary for delayed 6 p...
