Public health and evidence-informed policy-making: The case of a commonly used herbicide

Discussion Drawing conclusions on the causation of adverse health effects by environmental chemicals can have important societal consequences, leading to policy-making which can control, limit or even prevent the exposure to the pollutant through regulation and litigation. There are critical lessons to be learned from the Monsanto saga. The whole process of evidence-informed policy-making is under threat. The case of glyphosyte is by no means over; further research is needed to cover the knowledge gaps, but this should be done independently and with full transparency. The IARC Monographs provide the scientific evaluation of the evidence based on comprehensive review of the scientific literature, but it remains the responsibility of individual governments and other international organizations to recommend, if any, regulations, legislation and other public health interventions. The IARC Monographs evaluate the hazard, but the societal decisions take also other factors into account while making the risk management decisions. The risk management philosophies for pesticides in various countries are different – in the EU, for example, the hazards (inherent properties) are emphasized while, in the US, the utilitarian acceptable risk approach prevails. The active ingredients for pesticide formulations are under constant development. Sometimes the dominant role of one ingredient may have a damping effec t in the innovation paths. This seems to have been the case with the weed...

In this study, 5% w/v SMP dispersion was acidified to pH 2.4–3.0 using citric acid and heated at different conditions. Lowering pH resulted in dissolution of colloidal calcium phosphate from casein micelles, corresponding to lowered turbidity and reduced hydrodynamic diameter of dispersions. When heated for 10 min at different temperatures, 70 °C was the most effective to produce transparent dispersions; whereas a shorter heating time between 2 and 60 min was desired at 90 °C. The decreased turbidity after heating was attributed to weakened hydrophobic interaction between casein molecules based on f...

Novotny, Bing Peng, Liangli Yu, Pei ChenAbstractBroccoli is a popular brassica vegetable and its consumption may decrease the occurrence of cancer in certain populations. To gain insight into the metabolites that may induce physiological responses to broccoli intake, a non-targeted metabolomic approach and a targeted approach for analysis of glucosinolate metabolites were developed using high resolution accurate mass spectrometry. A human study was conducted in which 6 subjects consumed a single meal ...

The structure confirmation of the synthesized EOTPE was performed by different spectroscopic methods. The corrosion inhibition action of EOTPE in pickling acids (1.0 N HCl and1.0 N H2SO4) at different temperatures (30–60 °C) was tested by various surface and corrosion methods, including open circuit potential (...

CroceAbstractWe established that loss of miR-15a/16–1 genes on chromosome 13q14 is the most common alteration in Chronic Lymphocytic Leukemia (CLL) and that miR-15/16 are crucial negative regulator of BCL-2, an antiapoptotic gene overexpressed in most CLLs and in many other malignancies. We have also shown that miR-15/16 target ROR1, a cell surface receptor for Wnt5a which can enhance growth/survival of CLL cells. Interestingly, ROR1 is expressed by many cancers, but not by normal adult tis...

The presence of OMP changed the film-forming solution from Newtonian to non-Newtonian fluid. The addition of OMP and RAs decreased the crystalline of PVA due to the hydrogen bonds among RAs, OMP and PVA. An appropriate content of RAs ...

The combination of chemotherapy and other therapies would be a promising therapy strategy. Photothermal therapy (PTT) does not cause serious side effects and has dual control of time and space, which was considered to be a good method for combination with chemotherapy. Here, we modified multifunctional nanosheets based on in-situ gold nanoparticles (Au NPs) grown molybdenum disulfide...
