It has concluded that not all adaptations of this type of test are reliable. It has also concluded that there is a lack of standardization for the phytotoxicity test on a global scale, which makes the various researchers in the field end up promoting variations, adaptations for the phytotoxicity test; therefore, there is an urgent need for ways to compare these variations, as the innovation proposed by this work. With a single standard methodology, we conclude that it will make it possible to compare phytotoxicity in samples directly between countries and continents, being able to generate a worldwide panorama of phytotoxicity, publicizing and comparing the standardized phytotoxicity levels in each region.Insufficient sewage treatment facility is one important reason for wastewater entering and affecting aquatic ecosystems. The PPP mode, serving as one of the fastest-growing mechanisms for public service provision in recent decades, is considered to be an effective way to alleviate the pressure of funding shortages and to improve the efficiency of sewage treatment. However, the performance of PPPs has been questioned, especially the service quality given the inherent nature of the private sectors’ pursuit of maximizing economic profit and the shortcoming of incomplete contracts. This paper evaluates the service quality, namely the environmental performance, of the PPP mode in China’s urban sewage treatment sector. Based on detailed firm-level data in Jiangsu Province, China, we find that the PPP mode has improved the pollutant treatment performance, and increased operation cost and promoted sewage treatment efficiency serve as the main mechanism for the improvement of environmental performance. The research findings could help both developed and developing countries to apply and design a public-private partnerships mechanism.Groundwater is the dominant source of freshwater in many countries around the globe, and the deterioration in its quality by contaminants originating from anthropogenic sources raises serious concern. In this study, a scenario where groundwater is contaminated by acid mine drainage (AMD) from mining activities and/or sewage was envisaged, and the performance of a direct contact membrane distillation (DCMD) system was investigated comprehensively for different compositions of the AMD- and sewage-impacted groundwater. Regardless of the composition, MD membrane achieved 98-100% removal of metals and bulk organics, while the removal of the selected micropollutants ranged between 80 and 100%. Effective retention of contaminants by the MD led to their accumulation over time, which affected the hydraulic performance of the MD membrane by reducing the permeate flux by 29-76%. When persulfate (PS)-mediated oxidation process was integrated with the DCMD, degradation of bulk organics (50-71%) and micropollutants (50-100%) by PS reduced their accumulation. Characterisation of the fouling layer revealed the occurrence of membrane scaling that was mainly due to the deposition of iron oxide or oxyhydroxide precipitates. For an identical composition of the AMD- and sewage-impacted groundwater, flux decline was 10% less in PS-assisted DCMD as compared to that in the standalone DCMD. However, this did not prevent the formation of iron oxide scales on MD membrane during the operation of PS-assisted DCMD. This study demonstrates the long-term performance of a standalone and PS-assisted DCMD operated in continuous-flow mode to treat AMD- and sewage-impacted groundwater for the first time.Using antibody drug conjugates (ADC) which can exclusively bind to their target cells and upon internalization release their toxic agent, is one of the most effective methods for killing tumor cells. Therefore, increasing the internalization rate is an important factor for tumor treatment in this case. The aim of the present study was to develop a new variant of pertuzumab (an anti-ErbB2 humanized antibody) with higher internalization rate that can be a good candidate for the production of ADC. Selleck Doramapimod To this end, the Human Immunodeficiency Virus TAT Protein Transduction Domain (TAT-PTD) was replaced into the structure of the pertuzumab. At first, the best site in antibody heavy chain constant region for the replacement of TAT-PTD was predicted through computational methods. Then, the resulting recombinant antibody, of which TAT-PTD was located at amino acid position 130-140 and named Tatibody, was produced in CHO-S cell line. Finally, its physicochemical properties and biological activities were evaluated and compared with pertuzumab. Results showed that the binding ability of Tatibody to the ErbB2 receptor is similar to that of pertuzumab, but its internalization potency is 3.6 fold higher and can be used as a good candidate for ADC construction.Candida albicans is an opportunistic fungal human pathogen that has been causing an increasing number of deaths each year. Due to the widespread use of broad-spectrum antibiotics and immunosuppressants, C. albicans resistance to these therapies has increased. Thus, natural plant inhibitors are being investigated for treating C. albicans infections. Schinifoline is a 4-quinolinone alkaloid with antibacterial, insecticidal, antitumor, and other biological activities. Here, we explored the effects of schinifoline on C. albicans in C. elegans and extracted RNA from uninfected C. elegans, C. elegans infected with C. albicans, and C. elegans infected with C. albicans and treated with 100 mg/l schinifoline. Our results showed that there were significant differences among the three groups. The GO and KEGG pathway analysis suggested that the pathogenicity of C. albicans to C. elegans was caused by abnormal protein function. Schinifoline regulates lysosomal pathway related genes that accelerate the metabolism and degradation of abnormal proteins, thereby inhibiting the negative effects of C. albicans in vivo. These findings advance our understanding of the molecular mechanisms underlying schinifoline inhibition of C. albicans.The effect of κ-carrageenan (κ-C) on yolk over heat-induced gelation at natural yolk pH (6.2) and natural whole egg pH (7.5) was studied. The results showed the zeta potential values changed from -2.3 to -31.3 mV, from -8.6 to -28.6 mV for native pH yolk and pH 7.5 yolk because of the κ-C addition, respectively. These results indicated electrostatic interactions formed between protein and κ-C. The average area of holes formed by yolk gelation increased by κ-C addition. The addition of 1.0% κ-C decreased the gelling points from 62.1 to 54.4 °C, from 64.5 to 61. 6 °C for native pH and pH 7.5 yolk, respectively. A schematic model was established to show that κ-C enhances the yolk properties via electrostatic interactions. And the Fourier transform infrared (FTIR) spectroscopy verified the formation of κ-C-protein interactions. This study provides a guidance for designing novel food systems containing yolk and κ-C.
