The harsh natural environment on the Qinghai–Tibetan Plateau has a detrimental effect on the growth of vegetation. Elymus dahuricus, a widely distributed perennial herb on the Qinghai–Tibetan Plateau, is highly adapted to alpine regions. To unveil the mechanism of E. dahuricus adaptation to high altitude on the Qinghai–Tibetan Plateau, the relative photosynthetic characteristics and physiological...
Preclinical studies have suggested that increased adult neurogenesis in the hippocampus might have potential therapeutic effects for Alzheimer’s disease and depression; therefore, it is a target for the treatment of some brain diseases. In this technical communication, we propose a cell‑based fluorescence assay to study the neurogenesis of adult hippocampal progenitor cells that can be used for high‑throughput...
This study demonstrated the degradation of unionized acetate in anaerobic digestion at 45ºC through the identification of kinetics and inhibition parameters. The kinetic parameters, Ks and rmax, were determined using Monod-based model for three different conditions, namely uninhibited, inhibited, and systems with high substrate condition. The Ks values for uninhibited condition were in the range of...
Salix matsudana Koidz was exposed to different concentrations of Cd (0, 10, 50, and 100 µmol/L) to study the effects of Cd on mineral metabolism and antioxidant enzyme activities. The results showed that plant height and root length were inhibited by 50 and 100 µmol/L Cd, except the one under 10 µmol/L Cd treatment. The Cd content accumulated in different organs of S. matsudana, gradually increasing...
Background: Inflammation is an important pathogenic component of endotoxemiainduced acute kidney injury (AKI), finally resulting in renal failure. Diacerein is an interleukin-1β (IL-1β) inhibitor used for osteoarthritis treatment by exerting antiinflammatory effects. This study aims to investigate the effects of diacerein on endotoxemia-induced AKI. Methods: Male C57BL/6 mice were intraperitoneally...
The toxic effects of Cd on microtubule (MT) organization in root tip cells of S. matsudana were investigated in the present study using tubulin immunolabeling and fluorescence microscopy. Cell damage and expression level of the SmTUA1 gene in the root tips were also examined by means of propidium iodide (PI) staining and quantitative real-time PCR (qRT-PCR) technology. The MT arrays were very sensitive...
The effects of different NaCl concentrations (0.1, 0.2, and 0.4%) on plant growth, the enzymatic antioxidant system, lipid peroxidation, and cell damage were investigated in Salix matsudana Koidz to better understand the tolerant mechanism under NaCl stress. The results indicate that cell damage was induced in roots by NaCl stress as early as after just 1 h of exposure, which increased with increasing...
Based on basic equation and boundary layer theory of pneumodynamics, the thesis conducts numerical modeling and theoretical analysis on the last stage of turbine characteristics at a small volume flow by using FLUENT, gives an emphasized analysis on the position of first occurrence of backflow and its expansion direction and comes up with flow structure of the turbine flow field at last stage in the...
To understand the phytoremediation capability of Cd by Salix babylonica L. we studied Cd accumulation and translocation, antioxidant enzyme activities, lipid peroxidation, and soluble protein contents in S. babylonica exposed to 10, 50, and 100 μM Cd for 7, 14, 21, and 28 d. The results indicated that seedling growth was accelerated by 10 μM Cd, and significantly inhibited by 50 and 100 μM Cd. The...
