Ecological civilization construction in China is in its critical period and the natural resources assets are audited to the administration. However, the natural resources accounting is still in its infancy, especially the atmospheric environmental resources accounting, which refers to the ability of the atmospheric environment to accommodate and purify certain pollutants. This paper established a methodology to calculate the atmospheric resources assets with the index of SO, a convenient method to calculate the physical accounts for atmospheric environmental resources based on the capacity of SO and an accessible way to estimate the monetary accounts with market-based price. Based on the methodology, a calculation was conducted on the assets and liabilities of SO capacity resources for 31 provinces of China in 2015. Empirical results showed that the physical accounts for SO capacity resources quantify the environmental pollution status in each region, and the monetary accounts reflect whether the industry and energy structures in one region are sound and sustainable. The findings provide specific profit or loss in terms of physical and monetary accounts for each region, which enable to quantify the government's occupancy and affordability of SO capacity resources, and contribute to the establishment of natural resource balance sheet and ecological compensation mechanism.

Neglected tropical diseases (NTDs) represent a group of chronic and debilitating infections that affect more than one billion people, predominantly in low-income communities with limited health infrastructure. This paper analyzes the factors that perpetuate the burden of NTDs, highlighting how poor health infrastructure, unfavorable socioeconomic conditions and lack of therapeutic resources exacerbate their impact. The effectiveness of current interventions, such as mass drug administration (MDA) programs and improved sanitation, in reducing disease prevalence is examined.

Stinging nettle () is an herbaceous perennial plant native to Eurasia, wildly distributed throughout the temperate parts of the world. Although generally considered as a weed due to its fast growth and invasive capacity, stinging nettle is well suited to cultivation and is currently experiencing a revival as a beneficial crop due to its numerous potential applications. This interest reflects in an increasing number of scientific articles related to nettle in the last years.

In order to explore the water and fertilizer requirements of eggplants in the western oasis of the river, the experiment was conducted in Minle County of Gansu Province in 2022 and 2023 under three water stress gradients and three nitrogen application levels: (1) moderate water stress (W, 50-60% in field water capacity [FC]), mild water stress (W, 60-70% in FC), and full irrigation (W, 70-80% in FC); (2) low nitrogen (N, 215 kg·ha), medium nitrogen (N, 270 kg·ha), and high nitrogen (N, 325 kg·ha). Moderate and mild water stress were applied during eggplant flowering and fruiting while full irrigation was provided during the other growth stages; a control class (CK) was established with full irrigation throughout the whole plant growth without nitrogen application. This study investigated the effects of water-saving and nitrogen reduction on the yield, quality, and water-nitrogen use efficiency of eggplants in a cold and arid environment in the Hexi Oasis irrigation area of China.

Objectives: Polysaccharides from are known to have several bioactive effects. Previous studies have found that low-molecular-weight polysaccharide (GP1) is degraded by and promotes the production of beneficial bacteria and metabolites, which improves immune disorder and intestinal injury, and then enhances the body's immune regulation ability. However, the immune regulation effect of GP1 on a healthy body has not been studied.

Background: Abel () is widely cultivated and serves as an important source of edible oil. Yet, during oil production, pruned branches generate significant waste and contribute to environmental pollution.
Objectives: In this work, we obtain a natural polysaccharide from the branches of and optimize its extraction using Box-Behnken design (BBD), which is a statistical method commonly used in response surface methodology.
