Cellulose-based materials in environmental protection: A scientometric and visual analysis review.

As sustainable materials, cellulose-based materials have attracted significant attention in the field of environmental protection, resulting in the publication of numerous academic papers. However, there is a scarcity of literature that involving scientometric analysis within this specific domain. This review aims to address this gap and highlight recent research in this field by utilizing scientometric analysis and a historical review.

Indole-3-acetic acid improves periphyton's resistance to ultraviolet-B: From physiological-biochemical properties and bacteria community to livestock-polluted water purification.

Livestock-polluted water is a pressing water environmental issue in plateau pastoral regions, necessitating the adoption of eco-friendly solutions. Despite periphyton being a promising alternative, its efficacy is limited by the prevalence of intense ultraviolet radiation, particularly ultraviolet-B (UVB), in these regions. Therefore, this study employs molecular tools and small-scale trials to explore the crucial role of indole-3-acetic acid (IAA) in modulating periphyton characteristics and mediating nutrient removal from livestock-polluted water under UVB exposure.

The response of bacterial community to UVB was significantly different between immature periphyton and mature periphyton, but not for physiological indicators.

Periphyton has important ecological functions. It can even exist in environments with strong ultraviolet radiation. However, knowledge of periphyton under ultraviolet is limited, which limits the understanding and application of periphyton in environments with high ultraviolet radiation.

The effects of inorganic anions on degradation kinetics and isotope fractionation during the transformation of tris(2-chloroethyl) phosphate (TCEP) by UV/persulfate.

Tris(2-chloroethyl) phosphate (TCEP), as a typical chlorinated flame retardant, is attracting more attention as a carcinogen. Although persulfate-based oxidation exhibits good performance in removing refractory organic pollutants, the kinetics of persulfate-based remediation are affected by inorganic anions, which causes inaccurate remediation efficiency. This study combines steady-state radical concentration modelling with isotope fractionation to investigate the effects of inorganic anions on TCEP degradation by UV/persulfate (UV/PS).

Performance of basalt fiber-periphyton in deep-level nutrient removal: A study concerned periphyton cultivation, characterization and application.

Nutrients in centralized discharge area of treated sewage can cause high ecological risks to aquatic systems, thus a deep-level nutrient removal is necessary. Recently, periphyton has attracted increasing interests for its excellent performance in nutrient removal. In this study, the suitability and durability of basalt fiber (BF) as a new green carrier of periphyton was evaluated, and development process of basalt fiber-periphtyon (BFP) was tracked with bacterial community succession and physiological indicators.

Identification of 3, 4-disubstituted pyridine derivatives as novel CDK8 inhibitors.

Selective inhibition of cyclin-dependent kinase 8 (CDK8) has been recently regarded as a potential approach for cancer therapy. A series of novel CDK8 inhibitors with the pyridine core was identified via scaffold hopping from the known CDK8 inhibitor A-7. The new inhibitors were designed to improve the ligand efficiency so as to enhance drug-likeness.

Dredging project caused short-term positive effects on lake ecosystem health: A five-year follow-up study at the integrated lake ecosystem level.

Sediment dredging is a controversial technology for lake eutrophication control. A lengthy and holistic assessment is important to understand the effects of a dredging project on a lake ecosystem. In this study, a dredging project was followed for 5 years.

SAR study on ,-disubstituted pyrimidine-2,4-diamines as effective CDK2/CDK9 inhibitors and antiproliferative agents.

Cyclin-dependent kinases (CDKs) are pivotal kinases in cell cycle transition and gene transcription. A series of ,-diphenylpyrimidine-2,4-diamines were previously identified as potent CDK2/CDK9 inhibitors. To explore the SAR of this structural prototype, twenty-four novel ,-disubstituted pyrimidine-2,4-diamines were designed and synthesized.

Discovery of novel CDK inhibitors via scaffold hopping from CAN508.

Cyclin-dependent kinases (CDKs) are promising drug targets for various human diseases, especially for cancers. Scaffold hopping strategy was applied on CAN508, a known selective CDK9 inhibitor, and a series of pyrazolo[3,4-b]pyridine compounds were synthesized and evaluated in vitro as CDK2 and CDK9 inhibitors. Most compounds exhibited moderate to potent inhibitory activities against both CDK2/cyclin A and CDK9/cyclin T1 systems.

Water and sediment quality in Qinghai Lake, China: a revisit after half a century.

Qinghai Lake, situated on the Qinghai-Tibet plateau, is the largest lake in China. In this study, the water and sediment quality were investigated in Qinghai Lake, three sublakes, and five major tributaries. Both Na(+) and Cl(-) were found to be the major ions present in Qinghai Lake and the three sublakes, while Ca(2+) and HCO(3-) dominated the tributaries.
