Maternal fructose consumption during pregnancy and lactation is associated with metabolic dysregulation in offspring. We tested the hypothesis that fish oil (FO) supplementation during pregnancy and lactation improves fructose-induced metabolic dysregulation in postpartum dams and offspring mice. We therefore aimed to determine the effects of FO supplementation on metabolic disruption in neonatal mice and dams induced by a maternal high-fructose diet (HFrD). The weight of the offspring of dams fed with HFrD on postnatal day 5 was significantly low, but this was reversed by adding FO to the maternal diet. Feeding dams with HFrD significantly increased plasma concentrations of triglycerides, uric acid, and total cholesterol, and decreased free fatty acid concentrations in offspring. Maternal supplementation with FO significantly suppressed HFrD-induced hypertriglyceridemia and hyperuricemia in the offspring. Maternal HFrD induced remarkable mRNA expression of the lipogenic genes Srebf1, Fasn, Acc1, Scd1, and Acly in the postpartum mouse liver without affecting hepatic and plasma lipid levels. Microbiology inhibitor Although expression levels of lipogenic genes were higher in the livers of postpartum dams than in those of nonmated mice, HFrD feeding increased the hepatic lipid accumulation in nonmated mice but not in postpartum dams. These findings suggest that although hepatic lipogenic activity is higher in postpartum dams than nonmated mice, the lipid consumption is enhanced in postpartum dams during pregnancy and lactation. Maternal FO supplementation obviously suppressed the expression of these lipogenic genes. These findings coincide with reduced plasma triglyceride concentrations in the offspring. Therefore, dietary FO apparently ameliorated maternal HFrD-induced dyslipidemia in offspring by suppressing maternal lipogenic gene expression and/or neonatal plasma levels of uric acid.Predation of wildlife and livestock by large carnivores takes place within many ecological and institutional settings. In this paper, moose predation by wolves is studied within a Norwegian institutional setting where the landowners obtain the moose harvesting value and where the wolf population is strictly controlled by the wildlife authorities. An age-structured model consisting of four categories of the moose population (calves, yearlings and adult females and males) is formulated, and both maximum yield (MY) and maximum economic yield (MEY) harvesting are studied. We find that the direct effect of higher predation pressure on an age-sex category works in the direction of higher harvesting pressure of that group. However, this direct effect is accompanied by indirect effects working through the stock abundance of all age-sex groups, and the net effect is ambiguous. In the numerical analysis, it is shown that harvest of the adult categories typically will be the optimal strategy, irrespective of the fact that calves are the main target of the wolves.A mobile septage treatment unit was built in India using readily available filters and membranes (mesh fabric, sand, granular activated carbon (GAC), microfilter, ultrafilter) and installed on the bed of a small truck. The target application was emptying of septic or sewage holding tanks and concentration of suspended solids while generating a liquid that could be discharged. The system was evaluated for operational and treatment performance while processing septage in the field at 108 sites in Tamil Nadu, India. After one phase of evaluation (Phase I), the system was improved and three replicate systems with slight modifications were fabricated for a second round of evaluation (Phase II) alongside the original, but modified unit. In Phase I, 105 m3 of septage was processed at an average flow of 623 L h-1 and with high removal efficiencies 83% chemical oxygen demand (COD), 75% total suspended solids (TSS), and 98.4% total coliform (TC). In Phase II, the original and three new systems combined treated 168 m3 of septage. One of the new systems doubled in capacity and processed septage at an average flow of 2700 L h-1 while the other three averaged 1290 L h-1. The removal efficiencies in Phase II were 80% COD, 81% TSS, and 99% TC averaged between the four systems. Pass through of soluble contaminants (e.g. soluble COD, NH3-N) remain the primary challenge for treatment performance. Success may be limited with some septage due to seasonality, location, or septage age, and further validation and optimization may be necessary. However, the septage in this study was treated to local standards, and the system offers a method of onsite treatment while reducing the need of costly and often inefficient septage emptying services. Further, the system can be produced at a cost competitive to traditional septage hauling trucks.The Pesticide Concentration in Paddy Field (PCPF-1) model has been successfully used to predict the fate and transport of granular pesticides applied to the paddy fields. However, it is not applicable for pesticides in foliar formulation while previous studies have reported that foliar application may increase the risks of rice pesticide contamination to the aquatic environment due to pesticide wash-off from rice foliage. In this study, we developed and added a foliar application module into the PCPF-1 model to improve its versatility regarding pesticide application methods. In addition, some processes of the original model such as photodegradation were simplified. The updated model was then validated with data from previous studies. Critical parameters of the model were calibrated using the Sequential Uncertainty Fitting version 2 (SUFI-2) algorithm. The calibrated model simulated pesticide dissipation trend and concentrations with moderate accuracy in the two paddy compartments including rice foliage and paddy water. The accuracy of the predicted soil concentrations could not be evaluated since no observed data were available. Although the p-factor and r-factor obtained using the SUFI2 algorithm indicated that the uncertainty encompassed in the predicted concentrations was rather high, the daily predicted pesticide concentrations in rice foliage and paddy water were satisfactory based on the NSE values (0.36-0.89). The updated PCPF-1 model is a flexible tool for the environmental risk assessment of pesticide losses and the evaluation of agricultural management practices for mitigating pesticide pollution associated with rice production.
