In the present work, we tried to identify the mechanism why by which the steroid alcohols accumulated when hydroxypropyl-β-cyclodextrin (HP-β-CD) was present to enhance the sterol conversion rate. Compared with the bioconversion system without HP-β-CD, the reaction rate was greatly improved in presence of HP-β-CD, but the steroid alcohols largely accumulated concurrently. In a reaction system with an enhanced reaction rate, the higher intracellular NADH/NAD+ level was detected, and the production of steroid alcohols increased also. Mycobacterium neoaurum mutants with higher KshA activity (3-ketosteroid 9α-hydrolase, a monooxygenase hydroxylating the nucleus at C-9 at the expense of NAD(P)H consumption) reduced the steroid alcohol production, and in the meantime, the NADH/NAD+ level was decreased consequently. Further research found that oxygen availability was seriously inhibited by the cyclodextrin in a reaction system. These results indicated that NADH formed in the bioconversion was not properly regenerated via the respiratory chain because of the poor oxygen bioavailability. The inhibitory effect of cyclodextrin on oxygen bioavailability is a key factor for the metabolic flux redistribution toward steroid alcohols in phytosterol resting cells bioconversion.Nano-gold (Aunps) have emerged as promising options that exhibit unique features discrete from traditional materials suited for biomedical applications. Aunps were synthesized using flavonoid quercetin (Q) as reducing agent, and resultant nanoparticles were further conjugated with the flavonoid. The resultant nano-system was expected to perform a dual role as antibacterial and as antioxidant agent. Nano-gold surface plasmon peaks were recorded at 560 nm with size around 62 nm and having slim distribution pattern. Spherical particle with smooth surface was observed under TEM and AFM studies. TEM micrographs confirmed a homogeneous particle population of size around 30 nm. Quercetin association to nano-gold was corroborated through FTIR and EDAX analysis. Antioxidant nature of nano-gold prevented rapid oxidation of brilliant cresyl blue dye, in presence of sodium hypochlorite. Antimicrobial action of QuAunp was tested against Gram-negative bacteria Escherichia coli. this website Nano-gold designed produced a minimum inhibitory concentration of 7.6 μg/ml and minimum bactericidal concentration 10.5 μg/ml against E. coli. Further TEM analysis and membrane permeability studies revealed the impact of QuAunps on bacterial membrane leading to cell damage.This study investigates the heterogeneous effects of remittance inflows, institutional quality, foreign direct investment, energy consumption, financial development, and trade openness on the ecological footprint spanning from 1990 to 2016 for the global panel of 93 countries. The current study employs a panel quantile regression (PQR) approach for tickling the distributional and unobserved country-specific heterogeneity. The findings reveal that remittance inflows significantly enhanced the environmental degradation in 5th to 70th quantiles and it turns to becomes negative at 80th to 95th quantiles. Similarly, institutional quality also deteriorates the environmental quality in all quantiles except higher quantiles such as 90th and 95th quantiles, which shows the improved environmental quality. Furthermore, the results support the validity of an inverted U-shaped environmental Kuznets curve (EKC) hypothesis. In addition, financial development, energy consumption, and trade openness significantly deteriorate the environmental quality in the long run. In contrast, foreign direct investment improves environmental sustainability. Moreover, these findings are robust to various robustness analyses which confirm the consistency of the results. Related policy proposals are then offered according to our empirical findings.Behavior responses of organisms can be used as a non-invasive method for neurotoxicology studies since it directly links the nervous system's functioning and biochemical activities. Among different behavioral activities, aquatic organisms' swimming behavior (fitness) is the essential factor for health assessment; thus, it is practiced routinely in neurotoxicological studies. Zebrafish (Danio rerio) are excellent models for neurotoxicology studies. Based on the above information, we hypothesized that zebrafish's swimming behavior is a potential biomarker for neurotoxic effect assessment. We exposed zebrafish (length, 3-4 cm; weight, 0.2-0.3 g) to different synthetic organic chemicals (organophosphorus flame retardants (tri-cresyl phosphate and cresyl diphenyl phosphate) and neurotoxic pesticides (cypermethrin and methomyl) for 15 days. For each test chemical, we chose two different concentrations (Treatment-I 5 μL/L and Treatment-II 25 μL/L) to study their eco-toxicity. The swimming strength of zebrafish was quantified using an online monitoring system. The swimming strength of zebrafish decreased under different treatments (Treatment-I (5 μL/L) and -II (25 μL/L)) of target chemicals. The circadian rhythm of zebrafish was predominantly not affected in this study. Higher neurotoxic effect (behavioral impairment) was observed in Treatment-II when compare to Treatment-I of organophosphorus flame retardants and pesticides groups. Responses of zebrafish under organophosphorus flame retardant (tri-cresyl phosphate and cresyl diphenyl phosphate) treatments were identical with pesticide (cypermethrin and methomyl) treatments. Based on the results, we conclude that swimming behavior could be an ideal non-invasive biomarker to assess waterborne contaminants' neurotoxic effect.Loessal soil is one of the main cultivated soils in northwest China. Part of its distribution area was irrigated with industrial wastewater in past three decades. This caused heavy metal contamination in the soil. It had induced toxicity on crops and also threatened local human health for now. Based on a field plot experiment, effects of different Cu concentrations (from 45 to 2000 mg kg-1) in loessal soil on spinach plant growth and uptake of mineral nutrients (Zn, Fe, Mg, K, and Ca) by spinach were investigated. The Cu addition increased available concentrations of mineral nutrients in loessal soil and concentrations of Cu, Zn, Mg, and Ca in roots. The translocation of mineral nutrients from roots to leaves was inhibited under Cu addition, inducing their decrease in leaves. The EC10 and EC50 of soil Cu in relative dry weights of leaves were 240.33 mg kg-1 and 1205.04 mg kg-1, respectively. The PLS-PM analysis showed that available concentrations of nutrients in soil were only affected by Cu in soil positively, nutrients in roots were mainly affected by Cu in soil and Cu in leaves positively, nutrients in leaves were mainly affected by Cu in roots negatively, translocation of nutrients in spinach and plant growth were principally affected by Cu in leaves negatively, and the total effect of Cu in leaves on nutrients in roots and leaves, translocation of nutrients in spinach, and plant growth was the highest.
