Furthermore, artificial neural network models explained the variation in the secondary compounds very well via the combination of several different metabolites from WG and AG. Finally, C and N metabolism plays a key role in secondary compound biosynthesis in specific tissues and cultivation conditions and highlights large-scale metabolite patterns in WG and AG.A spatial mismatch in water and arable land availability results in large virtual water transfers through interprovincial food trade in China. Accurately identifying and measuring water-saving links in interprovincial food trade can help to relieve water resources pressure in main grain-producing areas. We use a multiregional input-output table combined with the CROPWAT model to build China's interprovincial virtual water transfer network embedded in food trade in 2012. Then, water saving and scarce water saving are measured. Both consider the difference in water productivity among provinces, but the latter also pays attention to the scarcity of water resources. Finally, we adopt a water footprint to recalculate the scarce water savings without precipitation (green water). Our results indicate that the amount of virtual water transfer embedded in food trade is 74.9 billion m3, which is equivalent to 12.22% of the total water use in 2012. We observe large variations in the relationship between water resources abundance and agricultural water-use efficiency across provinces. read more Especially, there is a virtual water transfer from provinces with high water productivity but a lack of water to provinces with low water productivity but an abundance of water. The scarce water saving can identify sustainable food trade links, which can alleviate water scarcity in consuming provinces without exacerbating water shortage in producing provinces. In addition, interprovincial food trade results in 15 billion m3 of scarce gray water saving, which is equivalent to 59.76% of the scarce blue water saving. Scarce water saving based on blue water and gray water provides a basis for establishing an interprovincial compensation mechanism to balance the cost of water redistribution caused by food trade.Debris poses a series of problems to marine life and human well-being. However, estimates of density and characteristics of debris found on beach surfaces and buried in the sand are patchy on a global scale and absent for West Africa. Here we investigate the density of surface and buried debris accumulated in two beaches with contrasting levels of urbanisation in Senegal, West Africa. We also describe type, colour, weight, size, and possible source of the 1766 items collected. The average density of debris buried at a depth of 10 cm (48.75 items/m2) was 25 times higher than that observed at the surface (1.92 items/m2). Plastics accounted for 97.62% of the items. Plastic bags and clothing plastic were the most common types, whereas white and transparent were the most common colours. Most items originated from mixed sources, i.e. beach users and land-based sources (51.30%). Debris density in the urbanised site was 20 times higher than that in the non-urbanised site. Debris density can, therefore, be largely underestimated when sampling only on the beach surface. Our study provides the first findings for future research on beach debris in Senegal.Although dissolved oxygen (DO) is a key factor for the removal of manganese (Mn) from aqueous solutions, this study presents an efficient method for Mn removal without any DO consumption. We demonstrate the feasibility of using an iron (Fe)-Mn co-oxide filter film to continuously remove Mn from groundwater under anaerobic conditions. A pilot-scale filter equipped with Fe-Mn co-oxide filter media (120 cm high) was adapted to explore the Mn removal performance under three DO levels (6-7 mg/L, 1-2 mg/L, and 0-0.2 mg/L). The Fe-Mn co-oxide filter exhibited a higher Mn removal performance under anaerobic conditions (no DO consumption) than under the other two DO conditions. The morphology, structure, and Mn valence changes of the Fe-Mn co-oxide filter film were studied using scanning electron microscopy (SEM), high-resolution transmission electron microscopy (HRTEM), Brunauer Emmett Teller (BET) theory, X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). The Fe-Mn co-oxide filter film under anaerobic conditions had a large contact surface area and large pore volume, and thus possessed more adsorption sites and reaction channels for Mn removal. By considering all of the characterization and reaction data reported in this study, we conclude that H2O ligands, hydrogen bonding (-OH), and vacant sites affect the transformation of Mn, thus play important roles in the continuous removal of Mn under anaerobic conditions. This discovery presents a new and effective approach for Mn removal during groundwater treatment.For the diagnosis of anti-MAG polyneuropathy the commercial ELISA manufacturer currently recommends a cut-off of 1000 Bühlmann Titer Units (BTU). We analyzed sera from 80 anti-MAG neuropathy patients and 383 controls (with other neuropathies or healthy controls) to assess the ELISA sensitivity and specificity at different thresholds. A better combination of sensitivity/specificity was found at a threshold >1500 BTU than at >1000 BTU. The best value of specificity was obtained at threshold >7000 BTU. There was a diagnostic grey area between 1500 and 7000 BTU in which the clinical phenotypes as well as electrophysiological studies need to be carefully assessed particularly to differentiate CIDP and anti-MAG neuropathy.Objective The aim of this systematic review was to evaluate the role of paternal sperm exposure before pregnancy on the risk of preeclampsia. Study design The search was conducted using electronic databases from inception of each database through October 2019. Review of articles also included the abstracts of all references retrieved from the search. Only studies evaluating exposure to paternal sperm before pregnancy on the risk of preeclampsia in the subsequent pregnancy were included. Exposure group was defined as significant exposure to paternal sperm, either measured by sexual cohabitation, oral sex habit, or by absence of barrier methods. Control groups was defined as minimal exposure to paternal sperm, either measured by lack of sexual cohabitation or oral sex habit, or by use of barrier methods. Sperm exposure identifiable before pregnancy that may be suspected to modify the risk of preeclampsia was examined. The primary outcome was the incidence of preeclampsia. Subgroup analyses by parity and type of sperm exposure were planned.
