Degradation of dimethyl phthalate through Fe(II)/peroxymonosulphate heightened by fulvic acid: efficiency and possible mechanism

Yi Ding, Min Zhang, Sijie Zhou, Linbei Xie, Ao Li & Ping Wang
Ferrous iron (Fe(II)) reacts with peroxymonosulphate (PMS) to form active oxidants that can degrade refractory organic pollutants. However, the conversion rate of Fe(III) to Fe(II) is slow, which limits its actual application. In the study, the effect of fulvic acid (FA) on the degradation of dimethyl phthalate (DMP) by Fe(II)/PMS was investigated. Moreover, the degradation process of DMP was predicted by the preliminary identification of active free radicals and intermediates. As expected, FA gave rise...

Stachydrine is effective and selective against blast phase chronic myeloid leukaemia through inhibition of multiple receptor tyrosine kinases

Ruixin Gu, Wei Zhang & Dandan Xu
Resistance to BCR-ABL tyrosine kinase inhibitor (TKI) is the cause of treatment failure in blast phase chronic myeloid leukaemia (BP-CML). Agents that act synergistically with BCR-ABL TKI are required to improve response. This work investigated the effects of stachydrine in CML. CML cells were treated with control or stachydrine at 20, 40 and 80 µM. Proliferation and apoptosis were examined after 72 h treatment. Combination studies were performed in four groups: control, TKI, stachydrine and...

Gold nanoparticles (AuNPs) were successfully fabricated by Pholiota adiposa polysaccharide (PAP-1a) without employing any other chemicals. The physical and chemical properties of PAP-AuNPs were determined using transmission electron microscopy (TEM), dynamic light scattering (DLS), energy-dispersive X-ray spectroscopy (EDXR), Fourier-transform infrared spectroscopy (FT-IR), and atomic force microscopy (AFM). In an attempt to analyze the immune regulation, antitumor effect, and biological safety, the production of NO and TNF-α, IL-12p70, and IL-1β from RAW264.7 as well as the...

A novel big data mining framework for reconstructing large-scale daily MAIAC AOD data across China from 2000 to 2020

Binjie Chen, Yang Ye, Cheng Tong, Jinsong Deng, Ke Wang & Yang Hong
Satellite-based aerosol optical depth (AOD) retrieval products are essential in air pollution and climate change research. Unfortunately, cloud contaminations and unfavorable surface conditions result in a considerable proportion of missing AOD data. Numerous studies have been conducted to reconstruct large-scale AOD data gaps by utilizing adjacent spatiotemporal information or modeling AOD data via various external geographical data. However, the erratic variation of AOD and the inconvenience of external data weaken the accuracy and efficiency of...

Help or punishment: acute stress moderates basal testosterone's association with prosocial behavior

Huagen Wang, Zhen Zhen, Ruida Zhu, Bohai Yu, Shaozheng Qin & Chao Liu
The gonadal hormone testosterone is well-recognized to facilitate various behaviors for obtaining social status. A good reputation (i.e. competitive, generous, and trustworthy) is of crucial importance for acquiring high social status. It is unclear which type of reputation is preferred by individuals under the influence of testosterone. Given that the recent dual-hormone hypothesis emphasizes the modulating effect of stress (cortisol) on the influence of testosterone, it would be intriguing to test the role of stress-induced...

Preventive effect of isostrictiniin from Nymphaea candida on carbon tetrachloride-induced hepatic fibrosis in mice

Hui juan Dong, Yuxuan Guo, Tao Liu & Jun Zhao
This study aimed to investigate the preventive effect of isostrictiniin (ISO) from Nymphaea candida against CCl4-induced hepatic fibrosis (HF) in mice. HF in mice was induced by intraperitoneally injecting 10% CCl4 olive oil solution twice a week. After intragastric administration for 8 weeks. ISO (25, 50, or 100 mg/kg) could significantly reduce the serum AST, ALT, ALP, HA, LN, PC-III, C-IV, IL-1β, and TNF-α levels in HF mice, and the collagen fiber deposition in ISO...

Acoustic triggered nanobomb for US imaging guided sonodynamic therapy and activating antitumor immunity

Mengmeng Li, Ya Zhu, Chao Yang, Mi Yang, Haitao Ran, Yefeng Zhu & Wei Zhang
We fabricated an ultrasound activated ‘nanobomb’ as a noninvasive and targeted physical therapeutic strategy for sonodynamic therapy and priming cancer immunotherapy. This ‘nanobomb’ was rationally designed via the encapsulation of indocyanine green (ICG) and perfluoropentane (PFP) into cRGD peptide-functionalized nano-liposome. The resulting Lip-ICG-PFP-cRGD nanoparticle linked with cRGD peptide could actively targeted ID8 and TC-1 cells and elicits ROS-mediated apoptosis after triggered by low-intensity focused ultrasound (LIFU). Moreover, the phase change of PFP (from droplets to...

Is Internalized Racism One More Piece of the Puzzle in Racial Disparities in Prosecution?

Besiki Luka Kutateladze & Lin Liu
Although diversifying the criminal justice apparatus may yield more equitable outcomes, empirical tests of how prosecutors’ race affects their decisions are limited. Informed by Internalized Racism Theory (IRT), we hypothesized that Black prosecutors would be most punitive toward Black defendants, followed by Latino/a defendants, and least toward White and Asian defendants. Employing hierarchical logistic modelling, we analyzed data from a large prosecutorial office to examine the extent to which prosecutors’ race is associated with racial...

Jia Liu, Wenjing Liu, Rui Tan, Weiming Huang, Bin Wang, Shuai Zhang & Minghui Zhang
The strain variations in Elm earlywood and latewood during drying were studied with digital image correlation method. Also, the moisture contents of different water states were quantified based on time-domain nuclear magnetic resonance technique to reveal the strain-water relationships. Although the shrinkage strains gradually increased with increasing drying time, there was a significant difference in the strain distribution of the earlywood and latewood. Owing to latewood large stress, the earlywood was pulled by it to...

A. caviae infection triggers IL-1β secretion through activating NLRP3 inflammasome mediated by NF-κB signaling pathway partly in a TLR2 dependent manner

Qiankun Yang, Jianguo Zhang, Feixue Liu, Huizhen Chen, Wei Zhang, Haitao Yang, Nana He, Jingquan Dong & Panpan Zhao
Aeromonas caviae, an important food-borne pathogen, induces serious invasive infections and inflammation. The pro-inflammatory IL-1β functions against pathogenic infections and is elevated in various Aeromonas infection cases. However, the molecular mechanism of A. caviae-mediated IL-1β secretion remains unknown. In this study, mouse macrophages (PMs) were used to establish A. caviae infection model and multiple strategies were utilized to explore the mechanism of IL-1β secretion. IL-1β was elevated in A. caviae infected murine serum, PMs lysates...
