The East Urals Radioactive Trace (EURT) was formed after a chemical explosion in the radioactive waste-storage facility of the Mayak Production Association in 1957 (Southern Urals, Russia) and resulted in an activity dispersion of 7.4 × 10(16) Bq into the atmosphere. Internal exposure due to ingestion of radionuclides with local foodstuffs was the main factor of public exposure at the EURT. The EURT cohort, combining residents of most contaminated settlements, was formed for epidemiological study at the Urals Research Center for Radiation Medicine, Russia (URCRM)...

Precision medicine is a new strategy for disease prevention and treatment by taking into account differences in genetics, environment and lifestyles among individuals and making precise diseases classification and diagnosis, which can provide patients with personalized, targeted prevention and treatment. Large-scale population cohort studies are fundamental for precision medicine research, and could produce best evidence for precision medicine practices. Current criticisms on precision medicine mainly focus on the very small proportion of benefited patients, the neglect of social determinants for health, and the possible waste of limited medical resources...

The reverse osmosis (RO) technology for desalination and demineralization serves the global water crisis context, both technically and economically, and its market is growing. However, RO membranes have a limited life-cycle and are often disposed of in landfills. The impacts caused by the disposal of thousands of tonnes per annum of RO membranes have grown dramatically around the world. Waste prevention should have a high priority and take effect before the end-of-life phase of a product is reached. In this review, a summary is presented of the main advances in the performance of the RO technology and the membrane lifespan...

This research focused on the inhibitory effects of Ca on the aerobic biological treatment of landfill leachate containing extremely high Ca concentrations. When the Ca concentration in leachate to be treated was more than 4500 mg l(-1), the total organic carbon removal rate was significantly reduced and the processing time to achieve the same removal efficiency was 1.4 times that in the control treatment without added Ca. In contrast, the total nitrogen and ammonia nitrogen (NH4(+)-N) removal efficiencies were positively related to the Ca concentration, increasing from 65...

The application of molecular methods has provided a new picture of the colon microbial flora, or microbiome. The microbiome has been found to be a complex ecosystem with multiple influences on its human host. In renal medicine, interest has focused on the microbiome as a source of toxic waste chemicals and a stimulant to unwanted systemic inflammation. Early attempts to manipulate the microbiome have yielded limited benefit, but further research is strongly motivated.

REVIEW
Benjamin A Musa Bandowe, Hannah Meusel
Nitrated polycyclic aromatic hydrocarbons (nitro-PAHs) are derivatives of PAHs with at least one nitro-functional group (-NO2) on the aromatic ring. The toxic effects of several nitro-PAHs are more pronounced than those of PAHs. Some nitro-PAHs are classified as possible or probable human carcinogens by the International Agency for Research on Cancer. Nitro-PAHs are released into the environment from combustion of carbonaceous materials (e.g. fossil fuels, biomass, waste) and post-emission transformation of PAHs...

Ultraviolet light emitting diodes (UV LEDs) have become widespread in chemical research as highly efficient light sources for photochemistry and photopolymerization. However, in more complex experimental setups requiring highly concentrated light and highly spatially resolved patterning of the light, high-pressure mercury arc lamps are still widely used because they emit intense UV light from a compact arc volume that can be efficiently coupled into optical systems. Advances in the deposition and p-type doping of gallium nitride have recently permitted the manufacture of UV LEDs capable of replacing mercury arc lamps also in these applications...
