The mechanism of DEHP degradation by the combined action of biochar and Arthrobacter sp. JQ-1: Mechanisms insight from bacteria viability, degradation efficiency and changes in extracellular environment.

Di(2-ethylhexyl) phthalate (DEHP) has been widely detected in soil, water, and sediment as a priority control pollutant. Immobilized microorganism technology is gradually mature and applied in production. Biochar prepared from agricultural wastes is an excellent immobilized carrier because of its porous structure and abundant functional groups.

Are biodegradable mulch films a sustainable solution to microplastic mulch film pollution? A biogeochemical perspective.

Mulch film residue contributes significantly to global plastic pollution, and consequently biodegradable mulch films (BDMs) are being adopted as a solution. BDMs decompose relatively quickly, but their complete biodegradation requires suitable conditions that are difficult to achieve in nature, causing biodegradable microplastics (bio-MPs) to be more likely to accumulate in soil than traditional microplastics (MPs). If BDMs are to be considered as a sustainable solution, long-term and in-depth studies to investigate the impact of bio-MPs on the biogeochemical processes are vital to agroecosystems operation and ecosystem services supply.

SphK-produced S1P in somatic cells is indispensable for LH-EGFR signaling-induced mouse oocyte maturation.

Germ cell division and differentiation require intimate contact and interaction with the surrounding somatic cells. Luteinizing hormone (LH) triggers epidermal growth factor (EGF)-like growth factors to promote oocyte maturation and developmental competence by activating EGF receptor (EGFR) in somatic cells. Here, we showed that LH-EGFR signaling-activated sphingosine kinases (SphK) in somatic cells.

Interference between di(2-ethylhexyl) phthalate and heavy metals (Cd and Cu) in a Mollisol during aging and mobilization.

Diffuse pollution of the soil by phthalates and heavy metals causes numerous concerns. Their respective fates when coexisting require further investigation. In this study, di(2-ethylhexyl) phthalate (DEHP) and Cd/Cu were used as subjects, focusing on their behavior in Mollisols under combined pollution based on their concentration, fractionation, and leaching.

Facilitating effect of heavy metals on di(2-ethylhexyl) phthalate adsorption in soil: New evidence from adsorption experiment data and quantum chemical simulation.

In terms of researching and treating farmland pollution, interactions between organic and inorganic pollutants are very important aspects. Herein, the effects of heavy metals on di(2-ethylhexyl) phthalate (DEHP) adsorption in soil were investigated. The presence of Cd/Cu increased the adsorption capacity of DEHP (>23%) in a nonlinear manner.

Establishment and validation of an RNA binding protein-associated prognostic model for ovarian cancer.

Background: Ovarian cancer (OC) is one of the most common gynecological malignant tumors worldwide, with high mortality and a poor prognosis. As the early symptoms of malignant ovarian tumors are not obvious, the cause of the disease is still unclear, and the patients' postoperative quality of life of decreases. Therefore, early diagnosis is a problem requiring an urgent solution.

Rapidly degradation of di-(2-ethylhexyl) phthalate by Z-scheme BiO/TiO@reduced graphene oxide driven by simulated solar radiation.

Di(2-ethylhexyl) phthalate (DEHP) is a priority environmental pollutant with carcinogenic, teratogenic, and mutagenic toxicity. Because it is widely used and ubiquitous in water, it is urgent to use a non-toxic, fast, and non-temperature dependent photocatalyst for degradation. Herein, a Z-scheme heterojunction composite catalyst consisting of BiO and TiO with reduced graphene oxide (rGO) as a two-dimensional template was designed and characterized.

Biodegradation of Di-n-butyl phthalate in rhizosphere and growth-promoting effect of Cucumis sativus Linn. by a novel Pseudomonas sp. DNB-S1.

Plant associated-bacteria can facilitate the host plant in overcoming contaminant-induced stress responses as well as improve plant development and growth. In this study, a successful approach was reported to reduce the Dibutyl phthalate (DBP) levels of polluted soil and, consequently, to improve cucumber growth. DBP suppressed development of cucumber seedings significantly, damage sub-cellular of root, especially the biomembrane system, and affected the microbial community structures of the soil.

Downregulation of Long Non-coding RNA Inhibits Gastric Cancer Cell Migration and Invasion Through Impairing Expression by Exerting Its Enhancer-Like Function.

Long non-coding RNAs (lncRNAs) have been shown to play important roles in many human diseases. However, their functions and mechanisms in tumorigenesis and development remain largely unknown. Here, we demonstrated that focally amplified lncRNA in epithelial cancer (FALEC) was upregulated and significantly correlated with lymph node metastasis, TNM stage in gastric cancer (GC).

[Bioinformatics analysis of expression and function of EXD3 gene in gastric cancer].

Objective: To investigate the differentially expressed genes between gastric cancer and normal gastric mucosa by bioinformatics analysis, identify the important gene participating in the occurrence and progression of gastric cancer, and predict the functions of these genes.

Methods: The gene expression microarray data GSE100935 (including 18 gastric cancer samples and normal gastric mucosal tissues) downloaded from the GEO expression profile database were analyzed using Morpheus to obtain the differentially expressed genes in gastric cancer, and a cluster analysis heat map was constructed. The online database UALCAN was used to obtain the expression levels of these differentially expressed genes in gastric cancer and normal gastric mucosa.

Electrochemiluminescent behavior of melatonin and its important derivatives in the presence of Ru(bpy)(3)(2+).

Melatonin and some of its important derivatives were found to be able to enhance the ECL of Ru(bpy)(3)(2+) in an alkaline Britton-Robinson buffer solution. The optimum conditions for the enhanced ECL, such as the selection of applied potential mode, type of buffer solution, pH effect and effect of Ru(bpy)(3)(2+) concentration have been investigated in detail in this paper. Under the optimum conditions, the enhanced ECL is linear with the concentration of melatonin and its derivatives over the wide range, and the detection limit for these compounds was found to be in the range of 5.

Synthesis, spectral, and thermal characterizations of Ni(II) and Cu(II) beta-diketone complexes with thenoyltrifluoroacetone ligand.

Two kinds of nickel(II) and copper(II) beta-diketone complexes derived from thenoyltrifluoroacetone ligand with blue-violet light absorption were synthesized by reacting free ligand and different metal(II) ions in sodium methoxide solution. Their structures were postulated based on elemental analysis, ESI-MS, FT-IR spectra and UV-vis electronic absorption spectra. Smooth films on K9 glass substrates were prepared using the spin-coating method.

Spectroscopic and thermal properties of short wavelength metal (II) complexes containing alpha-isoxazolylazo-beta-diketones as co-ligands.

Two new azo dyes of alpha-isoxazolylazo-beta-diketones and their Ni(II) and Cu(II) complexes with blue-violet light wavelength were synthesized using a coupling component, different diazo components and metal (II) ions (Ni2+ and Cu2+). Based on the elemental analysis, MS spectra and FT-IR spectral analyses, azo dyes were unequivocally shown to exist as hydrazoketo and azoenol forms which were respectively obtained from the solution forms and from the solid forms. The action of sodium methoxide (NaOMe) on azo dyes in solutions converts hydrazoketo form into azoenol form, so azo dyes are coordinated with metal (II) ions as co-ligands in the azoenol forms.

[Spectroscopy of alpha-isoxazoleazoxyl-beta-diketone derivatives and their tautomers].

In this paper, the IR and UV-Vis spectroscopy of five novel alpha-isoxazoleazoxyl-beta-diketone derivatives with different structures have been studied, and their keto-enol and azo-hydrazone tautomeric phenomena have been discussed. It was found that all compounds, which are in the solid or in the solution, exist in the form of hydrazodiketo and azoenol isomers. The authors can also see that there are two absorption bands which are in the range 246-262 nm and 326-339 nm, respectively, for all compounds in the UV spectra, and the intensities of long wavelength absorption bands which are attributed to azoenol forms are stronger than short wavelength absorption bands which are attributed to hydrazodiketo forms.
