A high dose of dexamethasone induces neurodegeneration by initiating the inflammatory processes that lead to neural apoptosis. A dexamethasone administration model induces overproduction of amyloid-β (Aβ) and tau protein hyperphosphorylation and shows abnormalities of cholinergic function similar to Alzheimer's disease (AD). This study aimed to investigate the protective effect of hexahydrocurcumin on the brain of dexamethasone-induced mice. The results showed that hexahydrocurcumin and donepezil attenuated the levels of amyloid precursor protein and β-secretase mRNA by reverse transcription polymerase chain reaction, decreased the expression of hyperphosphorylated tau, and improved synaptic function. Moreover, we found that hexahydrocurcumin treatment could decrease interleukin-6 levels by attenuating p65 of nuclear factor kappa-light-chain-enhancer (NF-κB) of activated beta cells. In addition, hexahydrocurcumin also decreased oxidative stress, as demonstrated by the expression of 4-hydroxynonenal and thereby prevented apoptosis. Therefore, our finding suggests that hexahydrocurcumin prevents dexamethasone-induced AD-like pathology and improves memory impairment.Although the Organization for Economic Co-operation and Development (OECD) member countries are largely regarded as a high human development index and high-income economies, evidence has continued to reveal the existential gap among the member countries drive toward achieving environmental sustainability. Giving this motivation, this research employed a panel quantile approach to examine the role of square of per capita income (the environmental Kuznets curve-EKC hypothesis) and per capita income, tourist arrivals, energy consumption, and urbanization on environmental quality in the panel of (31) selected OECD countries over the period 1995-2016. A handful of vital results were presented in the study. First, the evidence of EKC (inverted U-shaped) proposition is establish just for the lower quantiles while a no EKC (U-shaped) hypothesis is found from the 0.25th to 0.90th quantile. In specific, environmental quality starts to improve when the per capita real income peaked at 11, 271.13 USD (0.05th quantile) and 8, 604.15 USD (0.10th quantile) while the environment becomes damaged after income per capita becomes 89, 321.72 USD (0.25th quantile) and 36, 315.50 USD (0.50th quantile). Moreover, the effect of international tourism arrivals, urbanization, and energy consumption are all significant and damaging to environmental quality across the quantile but with a slightly minimized impact toward the upper quantile. Furthermore, there is statistical significant evidence of Granger causality at least from tourism development, energy consumption, urbanization, and per capita income to carbon emissions. Considering the aforementioned results, the study outlined relevant policy mechanism that is poised to guide the OECD member countries on the sustainable development path.Groundwater pollution seriously threatens water resource safety due to high-intensity land use throughout the world. However, the relationship between groundwater pollution characteristics and land use in alluvial plains is still unclear. In this study, the effects of land use on shallow groundwater quality and human health risk were investigated via two sampling campaigns in a typical alluvial plain, namely, Jianghan Plain, China. Results show that the shallow groundwater in this area was polluted by nitrogen (with average concentrations of 5.12 mg/L in the dry season and 4.46 mg/L in the rainy season) and phosphorus (0.29 and 0.13 mg/L in the two seasons, respectively). The nutrient concentrations during the dry season were significantly higher than those during the rainy season (p less then 0.05). Correlation analysis indicated that the concentration of nutrients was significantly positively correlated with cultivated land and negatively correlated with water and residence, suggesting that land use patter
