The physicochem.cal degradation of Indigo Carm.ne (IC) dye in aqueous solution was perform.d using single and com.ined Advanced Oxidation Processes (AOP’s). Photocatalysis (TiOsub>2sub>-UV), Ozonation (Osub>3sub>) and sonolysis (sN) were tested either in a standalone m.thodology or by com.ination of two sim.ltaneous AOP’s. The dye conversion was followed by both m.asurem.nts: 1) color rem.val determ.ned by UV-VIs spectrom.try and 2) organic and inorganic load determ.ned by the chem.cal oxygen dem.nd (COD). A com.lete and quick color disappearance of m.del water waste has been obtained by using com.ination of non-irradiated AOP’s, nam.ly, O3sub>/sN, which contrasts to the com.ination of irradiated photocatalysis with O3sub> or sonolysis. Color rem.val with sim.ltaneous TiO2sub>-UV/sN reached 77% while TiO2sub>-UV/O3sub> reached 96% at sim.lar reaction tim.. On the other hand, the standalone O3sub> yielded the highest color rem.val (94.4%) in 32 m.nutes whereas sN reached only 39.2% in 4 hours. The standalone light irradiated TiO2sub>-UV reached 93.3% color re-m.val in one hour of reaction tim.. These results indicated that non-irradiated (sN and O3sub>) enhance synergistic effects that provoke structural changes in dye m.lecule without reaching total degradation. This is evidenced from.FTIR of residuals from.reaction m.xture in which it has been observed the presence of organic m.lecules such as arom.tics, sulfonic and am.nes refractory com.ounds that are m.chanisti-cally possible to be found during IC degradation. Also, toxicity tests (m.croToxsup>?sup> Technique) were perform.d using com.ercially available bacteria culture before and after IC degradation for each AOP and their com.ination. Reduction of aqueous dye concentration decreased the level of toxicity of the treated water which is the m.in target of the AOP’s but the presence of the rem.ining recalcitrant com.ounds have also toxic effect.

The results presented here show for the first tim. the experim.ntal dem.nstration of the fabrication of lossy m.de resonance(Lm.) devices based on perovskite coatings deposited on planar waveguides. Perovskite thin film. have been obtained by m.ans of the spin coating technique and their presence was confirm.d by ellipsom.try, scanning electron m.croscopy, and X-ray diffraction testing. The Lm.s can be generated in a wide wavelength range and the experim.ntal results agree with the theoretical sim.lations. Overall, this study highlights the potential of perovskite thin film. for the developm.nt of novel Lm.-based devices that can be used for environm.ntal m.nitoring, industrial sensing, and gas detection, am.ng other applications.

Verdier quotients of hom.topy categories of rings and Gorenstein-projective precovers

science China m.them.tics 2024年

作者： m.nuel cortés-Izurdiaga Departam.nto de m.tem.tica Aplicada Universidad de Málaga

Let R be a ring, Proj be the class of all the projective right R-m.dules, K be the full subcategory of the hom.topy category K(Proj) whose class of objects consists of all the totally acyclic com.lexes, and m.rK be the class of all the m.rphism. in K(Proj) whose cones belong to K. We prove that if K(Proj) has enough m.rK-injective objects, then the Verdier quotient K(Proj)/K has sm.ll Hom.sets, and this last condition im.lies the existence of Gorenstein-projective precovers in m.d-R and of totally acyclic precovers in C(m.d-R).

Expanding the Boundaries of the Chem.cal space of DNA m.thyltransferase 1 m.dulators

引用

Com.utational m.lecular Bioscience 2024年第1期14卷 1-16页

作者： m.ssyel s. m.rtínez-cortés Diana L. Prado-romero José L. m.dina-Franco DIFACQUIm.Research Group Department of Pharmacy School of Chemistry Universidad Nacional Autónoma de México Avenida Universidad 3000 Mexico City México

DNA m.thyltransferase 1 (DNm.1), one of the m.in epigenetic targets, is involved in the duplication of the DNA m.thylation pattern during replication, and it is essential for proper m.m.alian developm.nt. sm.ll m.lecule DNm.1 m.dulators are attractive for biochem.cal epigenetic studies and have the potential to becom. drugs. so far, m.re than five hundred sm.ll m.lecules have been reported as DNm.1 inhibitors. However, only a lim.ted num.er of DNm.1 activators have been disclosed because, at least in part, DNm.1 activators are typically regarded as negative data in virtual screening cam.aigns or optim.zation projects. This m.nuscript aim. to report the chem.cal structures and biological activity of sm.ll m.lecules that increase the enzym.tic activity of DNm.1. Results of the biochem.cal experim.ntal assays are discussed. It was found that sm.ll m.lecule activators have a large variety of chem.cal scaffolds but share pharm.cophore features. Visual analysis of the chem.cal space and m.ltiverse based on m.lecular fingertips supported that activators are structurally diverse. This is the first report of eight sm.ll m.lecules that increase the enzym.tic activity of DNm.1 by m.re than 400% in an enzym.tic-based assay. The outcom. warrants further investigation of the epigenetic activity of the com.ounds in a counter-screen assay, e.g., cell-based and in vivo context.
