Vertical and horizontal variabilities of ammonia in an agricultural area of Southeast China.

Ammonia (NH) plays a crucial role in the global nitrogen cycle, the increased NH emissions from agricultural activities impacting air, soil, water quality, and human health. Accurately estimating both the vertical and horizontal transport distances of NH are important for effective pollution control. Therefore, we used a helium-filled balloon mounted sampler to analyze the vertical profiles of NH emissions and their seasonal variations in an agricultural area of southeast China.

A dataset for N natural abundance of soil ammonia volatilization.

Investigating the sources of ammonia (NH) in the atmosphere and the contribution of each source is essential for environmental pollution control. The presented dataset aims to provide N natural abundance (δN) data collected from different controlled treatments to fill the knowledge gap between insufficient data of soil δN-NH and accurately identifying atmospheric NH source apportionments. Our results showed that the overall δN-NH values emitted from soil ranged from -46.

Traceability of atmospheric ammonia in a suburban area of the Beijing-Tianjin-Hebei region.

Ammonia (NH) is one of the most important sources that have been linked to the formation of PM. Therefore, it is important to study the source contributions to atmospheric NH for air pollution control. Here we used N natural abundance (expressed by δN) values to quantify the source contributions to atmospheric NH in the Beijing-Tianjin-Hebei (BTH) region, which suffers from the country's worst air pollution.

IL-1β promotes cervical cancer through activating NF-κB/CCL-2.

Cervical cancer is a malignancy with high morbidity and mortality among women. Interleukin (IL)-1β, chemokine (C-C motif) ligand 2 (CCL-2), and activation of NF-κB have been proven to be closely related to the progression of various tumors. However, their role in cervical cancer remains unclear.

Changes of δN values during the volatilization process after applying urea on soil.

Ammonia (NH) volatilized from soils plays an important role in N cycle and air pollution, thus it is important to trace the emission source and predict source contributions to development strategies mitigating the environmental harmful of soil NH volatilization. The measurements of N natural abundance (δN) could be used as a complementary tool for apportioning emissions sources to resolve the contribution of multiple NH emission sources to air NH pollution. However, information of the changes of δN-NH values during the whole volatilization process under different N application rates are currently lacking.

Long Non-Coding RNA HULC Promotes Cervical Cancer Cell Proliferation, Migration and Invasion via miR-218/TPD52 Axis.

Objective: Long non-coding RNAs (lncRNAs) have been identified as important players in tumorigenesis. LncRNA highly upregulated in liver cancer (HULC) has been identified as a key regulator in the progression of various cancers. However, the functional role and the mechanisms of HULC in regulating cervical cancer cell behavior remain unclear.

Role and mechanism of the Th17/Treg cell balance in the development and progression of insulin resistance.

The pathogenic mechanism of insulin resistance and associated diseases such as metabolic syndrome and diabetes remains unclear. Since inflammatory cytokines secreted by T cells play an important role in immune system homeostasis, we evaluated the role of interleukin-6 (IL-6) and the Th17/Treg balance in insulin sensitivity and the underlying mechanism in a rat model. After establishing an insulin-resistant rat model, the rats were injected with anti-mouse IL-6R receptor antibody (MR16-1) to block IL-6.

[Diversified health education mode applied in oral health care of preschool children].

Purpose: In regard to the current problems and deficiencies of preschool children's oral health, diversity of health education intervention was carried out, and the effect was evaluated.

Methods: Three kindergartens in Pudong New District were randomly selected. The children's age ranged from 4 to 5 years old.
