The relative abundance of these edge sites was the most important factor controlling the oxidation rate, whereas surface passivation restricted oxidation only in the stirred-flow experiment. The Mn(III) edge sites were demonstrated to play a crucial role in the oxidation and therefore in controlling the long-term fate of As. This study provided an improved understanding of Mn oxide reactivity and the significance in the cycling of redox-sensitive metal(loid)s in the environment.The impoundment of dammed rivers accelerates phytoplankton succession from river-dominated to lake-dominated species. Little is known about the role of phytoplankton succession in methane (CH4) production. In this study, we performed a 61-day microcosm investigation to simulate the collapse processes of Cyclotella meneghiniana (river-dominated algae) and Chlorella pyrenoidosa and Microcystis aeruginosa (lake-dominated algae). The results suggested that different methanogenic conditions were induced by the collapse of river-and lake-dominated algae. The rapid settlement of C. meneghiniana induced aerobic conditions in the water that inhibited anaerobic CH4 production and intensified CH4 oxidation as a result of an increase in pmoA. However, the decomposition of C. pyrenoidosa and M. aeruginosa depleted dissolved oxygen and provided abundant labile organic matter, which jointly elevated mcrA and the mcrA/pmoA ratio. Under this condition, anaerobic CH4 production was the dominant pathway for the mineralization of algae-derived carbon. Finally, the CH4 produced per unit of particulate total carbon (identified as the carbon content of the algal biomass) by C. pyrenoidosa and M. aeruginosa was 16.29-fold and 8.56-fold higher, respectively, than that produced by C. meneghiniana. These observations provided evidence that lake-dominated algae played a more vital role in CH4 production than river-dominated algae when algal succession occurred. This discovery might be a new and vital, yet largely underestimated CH4 emission pathway in river-reservoir systems, that should be considered when evaluating the effect of hydraulic projects on greenhouse gas emissions.Water contamination with the enteroprotozoan parasite Cryptosporidium is a current challenge worldwide. Solar water disinfection (SODIS) has been proved as a potential alternative for its inactivation, especially at household level in low-income environments. This work presents the first comprehensive kinetic model for the inactivation of Cryptosporidium parvum oocysts by sunlight that, based on the mechanism of the process, is able to describe not only the individual thermal and spectral actions but also their synergy. Model predictions are capable of estimating the required solar exposure to achieve the desired level of disinfection under variable solar spectral irradiance and environmental temperature conditions for different locations worldwide. The thermal contribution can be successfully described by a modified Arrhenius equation while photoinactivation is based on a series-event mechanistic model. The wavelength-dependent spectral effect is modeled by means of the estimation of the C. parvum extinction coefficients and the determination of the quantum yield of the inactivation process. Model predictions show a 3.7% error with respect to experimental results carried out under a wide range of temperature (30 to 45 °C) and UV irradiance (0 to 50 W·m-2). Furthermore, the model was validated in three scenarios in which the spectral distribution radiation was modified using different plastic materials common in SODIS devices, ensuring accurate forecasting of inactivation rates for real conditions.High salt diet (HSD), considered a public health problem worldwide, is associated with chronic degenerative diseases including renal diseases. However, little is known about the effects of HSD on renal function independently of the development of hypertension. To address the hypothesis that HSD induces renal injuries even without changes in blood pressure, BALB/c mice were fed for 7 days with chow with a high salt content (0.3-8%). Blood pressure did not change and there was a decrease in cortical (Na+ + K+)ATPase and NHE3 exchanger and an increase in renal fractional excretion of sodium. Nintedanib cell line Positive correlations between Na+ intake or urinary sodium excretion with proteinuria were found. HSD did not change glomerular function and structure, but induced tubule-interstitial injury measured by an increase in collagen deposition, interstitial space and γ-GT activity, a marker of tubular injury. These effects were associated with a decrease in cortical albumin reabsorption and megalin expression. Similarly, the addition of NaCl 20 mM to the incubation medium of LLC-PK1 cells reduced megalin expression and albumin endocytosis indicating that HSD could have a direct effect on proximal tubule cells. Furthermore, tubule-interstitial injury was associated with pro-inflammatory and pro-fibrotic phenotypes with an increase in Th1 and Th17 phenotypes and a decrease in Tregs followed by increases in IL-6, -17, -10, TNF-α, IFN-γ and TGF-β. Our results reveal a complex network involved in renal injuries induced by HSD independently of changes in blood pressure. These findings strengthen the importance of restriction of salt intake for the general population even for salt-resistant individuals.Palmitoleic acid (POA, 161n-7) is a lipokine that has potential nutraceutical use to treat non-alcoholic fatty liver disease. We tested the effects of POA supplementation (daily oral gavage, 300 mg/Kg, 15 days) on murine liver inflammation induced by a high fat diet (HFD, 59% fat, 12 weeks). In HFD-fed mice, POA supplementation reduced serum insulin and improved insulin tolerance compared with oleic acid (OA, 300 mg/Kg). The livers of POA-treated mice exhibited less steatosis and inflammation than those of OA-treated mice with lower inflammatory cytokine levels and reduced toll-like receptor 4 protein content. The anti-inflammatory effects of POA in the liver were accompanied by a reduction in liver macrophages (LM, CD11c+; F4/80+; CD86+), an effect that could be triggered by peroxisome proliferator activated receptor (PPAR)-γ, a lipogenic transcription factor upregulated in livers of POA-treated mice. We also used HFD-fed mice with selective deletion of PPAR-γ in myeloid cells (PPAR-γ KOLyzCre+) to test whether the beneficial anti-inflammatory effects of POA are dependent on macrophages PPAR-γ.
