The cumulative impact of temperature and nitrogen availability on the potential nitrogen fixation and extracellular polymeric substances secretion by Dolichospermum.

Nitrogen-fixing cyanobacteria not only cause severe blooms but also play an important role in the nitrogen input processes of lakes. The production of extracellular polymeric substances (EPS) and the ability to fix nitrogen from the atmosphere provide nitrogen-fixing cyanobacteria with a competitive advantage over other organisms. Temperature and nitrogen availability are key environmental factors in regulating the growth of cyanobacteria.

How does exotic Spartina alterniflora affect the contribution of iron-bound organic carbon to soil organic carbon in salt marshes?

Iron-bound organic carbon (OC-Fe) is important for the stability of soil organic carbon (SOC) in salt marshes, and the Spartina alterniflora invasion reshaped local salt marshes and changed the SOC pool. To evaluate the effects of S. alterniflora invasion on the contribution of OC-Fe to SOC, we determined the OC-Fe content and soil characteristics in the 0-50 cm soil profile along the vegetation sequence, including mudflats (MF), S.

Association of plasma homocysteine with peripheral arterial disease in the hypertensive adults: A cross-sectional study.

Increased plasma homocysteine (Hcy) has been identified as one of the important risk factors for cardiovascular disease. However, the association between plasma Hcy and peripheral artery disease (PAD) is still controversial. This study aimed to investigate the association between plasma Hcy and PAD and the potential modifier factors in Chinese hypertensive adults.

Effects of extracellular polymeric substances on the aggregation of under increasing temperature.

Aphanizomenon flos-aquae () blooms are serious environmental and ecological problems. Extracellular polymeric substances (EPSs) are among the most important indicators for the growth and aggregation of . In this study, the secretion of the EPS matrix under temperature rise (7-37°C) was investigated and the role of this matrix in aggregation was quantified.

Incorporation of DDR2 clusters into collagen matrix via integrin-dependent posterior remnant tethering.

Cell-matrix interactions play critical roles in cell adhesion, tissue remodeling and cancer metastasis. Discoidin domain receptor 2 (DDR2) is a collagen receptor belonging to receptor tyrosine kinase (RTK) family. It is a powerful regulator of collagen deposition in the extracellular matrix (ECM).

3-Acetyl-oleanolic acid ameliorates non-alcoholic fatty liver disease in high fat diet-treated rats by activating AMPK-related pathways.

3-Acetyl-oleanolic acid (3Ac-OA) is a derivative of oleanolic acid (OA), which has shown therapeutic beneficial effects on diabetes and metabolic syndrome. In this study we investigated whether 3Ac-OA exerted beneficial effect on non-alcoholic fatty liver disease (NAFLD) in rats and its potential underlying mechanisms. Treatment with 3Ac-OA (1-100 μmol/L) dose-dependently decreased the intracellular levels of total cholesterol (TC) and triglyceride (TG) in FFA-treated primary rat hepatocytes and human HepG2 cell lines in vitro.

MAD ointment ameliorates Imiquimod-induced psoriasiform dermatitis by inhibiting the IL-23/IL-17 axis in mice.

Psoriasis is a chronic auto-immune inflammation disease with skin lesions and abnormal keratinocyte proliferation. The IL-23/IL-17 axis plays an important role in the pathogenesis of psoriasis. Madecassoside (MAD) was the most important constituents isolated from Centella asiatica, which has long been used in dermatology, and it is supposed that MAD may have effects on psoriasis.

[Evolvement of soil quality in salt marshes and reclaimed farmlands in Yancheng coastal wetland].

Through vegetation investigation and soil analysis, this paper studied the evolvement of soil quality during natural vegetation succession and after farmland reclamation in the Yancheng coastal wetland of Jiangsu Province. Along with the process of vegetation succession, the soil physical, chemical, and biological properties in the wetland improved, which was manifested in the improvement of soil physical properties and the increase of soil nutrient contents, microbial biomass, and enzyme activities. Different vegetation type induced the differences in soil properties.

[Influence of salt marsh vegetation on spatial distribution of soil carbon and nitrogen in Yancheng coastal wetland].

Soil samples under different salt marsh vegetations in Yancheng coastal wetland were collected, and their organic carbon (C) and total nitrogen (N) were determined, aimed to analyze the influence of salt marsh vegetation on the spatial distribution of soil carbon and nitrogen. The results showed that the organic C and total N contents in top soils varied from 1.71 to 7.

[Emergy analysis on an added loop in Spartina alterniflora ecological engineering].

Based on the principle of multi-grade utilization of resources to get ecological, economic and social benefits of ecological engineering, this paper designed an added loop, following the Spartina alterniflora Ecological Engineering (SAEE). All the added loop design included SAEE, and the capsule was named SAEEC. In the added loop design, the Biological Mineral Liquid (BML) was made into antihyperlipidemia capsules, of which, the total flavonoids added up to 9.
