Comparison of with-mussel versus no-mussel tank water contamination across pooled trials showed significant (P less then 0.05) reduction in water exposed to mussel filtration for both, Enterococcus and E. coli trials. For Enterococcus trials, measures of turbidity (suspended particle density) were taken concurrently with measures of bacterial contamination. Regression of contamination against turbidity, with measures standardized across trials, yielded a significant positive association (n = 50, P less then 0.0001) across all tank water with a mussel. Thus, contamination reduction was associated with particle removal by mussel filtration.In this study, components, concentrations, distribution characteristics and sources of low molecular weight organic acids (LMWOAs) in seawater of the Changjiang Estuary and its adjacent East China Sea were investigated in March 2015. Lactic, acetic and formic acids were identified with their concentration range of 0-16.7, 0-42.7 and 0-6.7 μmol·L-1, respectively. MAPK inhibitor In the surface seawater, high concentrations of LMWOAs appeared in the sea area close to the estuary and along the coast. LMWOAs were important fractions of dissolved organic carbon and acetic acid was dominant component of LMWOAs. Riverine, terrestrial input, phytoplankton and sediment release were important sources for the LMWOAs, and human activities were considered as dominant sources for them in sampling period. The consistency of regions with high concentrations of LMWOAs, eutrophication, seasonal hypoxia and frequent red tide occurrence suggested LMWOAs as potential indicators for evaluating pollution status in coastal areas.The stochastic switching between microtubule growth and shrinkage is a fascinating and unique process in the regulation of the cytoskeleton. To understand it, almost all attention has been focused on the microtubule ends. However, recent research has revived the idea that tubulin dimers can also be exchanged in protofilaments along the microtubule shaft, thus repairing the microtubule and protecting it from disassembly. Here, we review the research describing this phenomenon, the mechanisms regulating the removal and insertion of tubulin dimers, as well as the potential implications for key functions of the microtubule network, such as intracellular transport and cell polarization.
The COVID-19 pandemic is putting healthcare workers across the world in an unprecedented situation. The purpose of this study was to evaluate the levels of depression, anxiety, and stress among Hubei pediatric nurses during the COVID-19 pandemic and to analyze the potential factors associated with them.

A self-designed online questionnaire survey, which consisted of the demographic and selected features, the occupational protection knowledge, attitudes, and practices of COVID-19, and the Chinese version of Depression, Anxiety, and Stress Scale, were used to assess the levels of depression, anxiety, and stress among Hubei pediatric nurses during COVID-19 pandemic. The logistic regression analyses were performed to analyze the potential factors associated with depression, anxiety, and stress.

A total of 617 pediatric nurses were included in the survey. A considerable proportion of pediatric nurses reported symptoms of depression (95 [15.4%]), anxiety (201 [32.6%]), and stress (111 [18.0%]). Results of mulork requirements and intensifying occupational protection practices might help safeguard pediatric nurses from depression, anxiety, and stress.In this work, three series of ω-3 polyunsaturated fatty acid-alkanolamine derivatives (PUFA-AAs) were synthesized, characterized and their anti-inflammatory activity in vivo was evaluated. Compounds 4a, 4f, and 4k exhibited marked anti-inflammatory activity in LPS-stimulated RAW 264.7 cells. The most promising compound 4k dose-dependently suppressed the cytokines with IC50 values in the low micromolar range. Further, 4k exhibited potential in vitro Nur77-binding affinity (Kd = 6.99 × 10-6 M) which is consistent with the result of docking studies. Next, the anti-inflammatory mechanism of 4k was found to be through NF-κB signal pathway in a Nur77-dependent manner. Moreover, we also observed 4k significantly inhibited LPS-induced expression of cytokines (IL-6, TNF-α, and IL-1β) through suppressing NF-κB activation and attenuated LPS-induced inflammation in mouse acute lung injury (ALI) model. In conclusion, the study strongly suggests that the PUFA-AA derivatives can be particularly as new Nur77 mediators for further treatment in inflammatory diseases.The indole scaffold has been recognized, over the years, as a model for the synthesis of compounds with anticancer activity by dint of its substantiated ability to act via multiple mechanisms, which also involves the inhibition of enzymes engaged in DNA replication. In this regard, a new series of indole and pyranoindole derivatives have been prepared, some of which showed good antitumor activity and proved their inhibitory effects on the tubulin target. The anticancer activity of the newly synthesized compounds has been evaluated on breast cancer cell lines, as MCF-7 and MDA-MB231, cervical cancer cells line HeLa and Ishikawa endometrial cancer cell line. Among the compounds under study, 7 exhibited a good antitumor activity on HeLa cell line (IC50 = 3.6 ± 0.5), leading to cell death by apoptosis due to the inhibition of tubulin polymerization, which demonstrated that the compound can explicate its function in a similar way to Vinblastine, a well-known inhibitor of tubulin polymerization. The data were also confirmed by in silico assays. No cytotoxicity against normal cells has been detected. Furthermore, in order to investigate the antioxidant properties, DPPH and ABTS tests were performed, together with fluorescence assays on 3T3-L1 cells. All our findings taken together led us to consider compound 7 a favourable candidate for the battle against cancer.In the present study, the titanium decorated iron oxide (Ti@Fe2O3) nanocomposites are synthesized using the chemical method. The as-prepared nanocomposite was characterized for successful formulation and the elemental spectra showed the composition of Fe (44%), Ti (0.71%) and O (55%) is confirmed the homogenous distribution. Crystallographic spectra depict the strong peaks corresponding to the of TiO2 and Fe2O3 nanoparticles planes with minor shift variation due to the formulation of Ti on the surface of Fe2O3 nanoparticles and it is also confirmed with SAED analysis. The X-ray photoelectron spectroscopy (XPS) analysis of Ti@Fe2O3) nanocomposite confirms the existence of elements such as Fe, O and Ti. Further, the morphology of the composite showed the well-defined encapsulation and aggregation of TiO2 nanoparticles on the surface of Fe2O3 nanoparticles. Further, the TiO2 nanoparticles showed less cytotoxic activity against bovine satellite cells, as well the nanocomposite increased the growth of bovine satellite cells comparing with control cells.
