Mechanism analysis showed that TCC exposure significantly inhibited the relevant biological processes, such as ammonia oxidation, denitrification, phosphorus release and uptake, which were closely relevant to nitrogen and phosphorus removal.As population and consumption grow, so does crop production and its residue. Crop residue is traditionally burned in developing countries, which impacts environment, economy, society and health. Thailand faces similar challenges as it is among the largest producers of rice paddy and sugarcane in the world with 83% of its total burnt residue coming from these crops. To address this problem, the Government of Thailand has implemented some policies (e.g. Alternative Energy Development Plan (AEDP) and zero burning policy for sugarcane) targeting both, the use of residue, and the practice of burning. While these policies appear to control residue burning to some extent, there are still challenges, especially for poorer farmers, who rely on manual harvesting practices. The paper looks into the current status of rice and sugarcane residue burning, its impacts on the environment, existing policies, current challenges, and future solutions through sustainable management practices. CP673451 To achieve reduction in residue burning, the best possible solution is to use residue for alternative purposes. Some sustainable management practices include use of residue for energy production, green harvesting to improve soil nutrients, biochar production and composting. Thailand can also learn from solutions implemented in other countries, to reduce some of the impacts of crop residue burning.Adsorption technology has been widely developed and employed for water and air pollution control. Conjugated microporous polymers (CMPs) emerge as the appropriate adsorbents candidate. To fulfill high capacity and good selectivity for the adsorption, strategies of flexible micropores design and functional group modification that facilitate the physical and chemical effect are considered desirable. The review firstly summarizes the advancements in structural studies of CMPs and the applications for contaminants adsorption from water and air. Further, the mechanisms involved in the remarkable capacity and selectivity of CMPs adsorbents are addressed. Finally, upcoming research efforts on materials design, adsorption principle, and resource recovery to overcome current practical bottlenecks are proposed.Effectively balancing soil moisture and biodiversity restoration remains a contentious issue for managers and researchers in the Loess Plateau region of China, even after many years of restoration efforts. We conducted a regional study on the trade-off between soil moisture and species diversity using spatial grid sampling in a semi-arid steppe (200-300 mm annual precipitation) in the northwest Loess Plateau. Results reveal that only soil moisture between 20 and 60 cm depth was significantly correlated with diversity indexes. Root-mean-square deviation (RSMD, the index of the soil water-biodiversity relationship) increased by monotonous linear trends with soil moisture in 20-60 cm depth. The linear relationship for Shannon Wiener diversity index (SD) was stronger than for species richness index (SR). When soil moisture in 20-60 cm depth was lower than 6-8%, RSMD often was less than zero, representing the trade-off relationship. However, synergism was more common as the soil moisture increased beyond 6-8%. The overall trends and the soil moisture threshold (6-8%) did not differ significantly between sites with different vegetation cover and aspect, though there were differences in the relative ratio of trade-off and synergism samples. Comparing results from sampling at different scales in the Loess Plateau suggests 6-8% soil moisture in 200-300 mm precipitation gradient, consistent with 370 mm rainfall depth in 250-550 mm precipitation gradient, might be a scale-independent threshold driving the soil moisture-biodiversity relationship from trade-off to synergism in the region.Discovering acetylcholinesterase (AChE) inhibitors is one of the important ways to develop new drugs for the treatment of Alzheimer's disease. In this work, a simple strategy was developed for screening AChE inhibitors from traditional Chinese medicines (TCMs) by capillary electrophoresis (CE) analysis combined with enzymatic assay, in which immobilized AChE was employed. For AChE immobilization, cellulose filter paper (CFP) was used as the carrier material and physically coated with chitosan owing to moderate viscosity of chitosan to be introduced into amino groups, and then AChE was covalently bonded to the amino-functionalized CFP through a Schiff base reaction using glutaraldehyde (GA) as a cross-linking agent. The CFP-immobilized AChE exhibited enhanced endurance to pH and temperature, improved storage stability, excellent repeatability and reusability. More remarkably, CFP-immobilized AChE can be instantly separated from enzyme reaction mixture thus greatly simplifying the operational process. For immobilized AChE, the Michaelis-Menten constant, inhibition constant and IC50 were determined using huperzine A as a model inhibitor. Finally, CFP-immobilized AChE was applied to inhibitor screening from 17 TCMs, among which Chebulae Fructus (ripe fruits of Terminalia chebula) exhibited the strongest inhibitory effect on AChE. The positive results indicated that such a screening strategy may open up a new avenue to discover active components from TCMs.Development of rapid and reliable immunochemical methods for monitoring psilocybin (4-phosphoryloxy-N,N-dimethyltryptamine; Pyb) and psilocin (dephosphorylated metabolite; Psi), the psychoactive compounds contained within hallucinogenic mushrooms (magic mushrooms), is desirable in order to identify these mushrooms and regulate their illicit use. Because no antibody was publicly available for this purpose, we generated two independent monoclonal antibodies (mAbs) against Pyb or Psi, and then developed enzyme-linked immunosorbent assays (ELISAs) by using them. To generate the specific antibodies, novel immunogenic conjugates were prepared by linking Pyb or Psi molecules to carrier proteins by modifying their 2-(N,N-dimethylamino)ethyl side chains. Spleen cells from mice immunized with these conjugates were fused with P3/NS1/1-Ag4-1 myeloma cells, and hybridoma clones secreting anti-Pyb and anti-Psi mAbs were established. These mAbs were characterized for their biochemical features and then applied to competitive ELISAs, which used microplates coated with Pyb or Psi linked with albumin.
