The widespread use of microplastics (MPs) has led to an increase in their discharge to wastewater treatment plants. However, the knowledge of impact of MPs on macro-performance and micro-ecology in simultaneous nitrification, denitrification, and phosphorus removal (SNDPR) systems is limited, hampering the understanding of potential risks posed by MPs. This study firstly comprehensively investigated the performance, species interactions, and community assembly under polystyrene (PS) and polyvinyl chloride (PVC) exposure in SNDPR systems.

This study proposed an efficient framework for optimizing the design and operation of combined systems of wastewater treatment plants (WWTP) and constructed wetlands (CW). The framework coupled a WWTP model with a CW model and used a multi-objective evolutionary algorithm to identify trade-offs between energy consumption, effluent quality, and construction cost. Compared to traditional design and management approaches, the framework achieved a 27 % reduction in WWTP energy consumption or a 44 % reduction in CW cost while meeting strict effluent discharge limits for Chinese WWTP.

The long-term survival rate of hepatocellular carcinoma (HCC) is poor. One of the reasons for the poor rate of survival is the high rate of recurrence caused by intrahepatic metastas is that adversely affects long-term outcome. Many studies have indicated that microRNAs play an important role in HCC, but there has been no research of clonal origins on recurrent HCC (RHCC) by analzing microRNAs.

Background: FOXP3 has been discovered to be expressed in tumor cells and participate in the regulation of tumor behavior. Herein, we investigated the clinical relevance and biological significance of FOXP3 expression in human hepatocellular carcinoma (HCC).

Methods: Expression profile of FOXP3 was analyzed using real-time RT-PCR, western blotting and immunofluorescence on HCC cell lines, and immunostaing of a tissue microarray containing of 240 primary HCC samples.

Multifocal tumors developed either as independent tumors or as intrahepatic metastases, are very common in primary liver cancer. However, their molecular pathogenesis remains elusive. Herein, a patient with synchronous two hepatocellular carcinoma (HCC, designated as HCC-A and HCC-B) and one intrahepatic cholangiocarcinoma (ICC), as well as two postoperative recurrent tumors, was enrolled.

Unlabelled: The molecular pathogenesis of intrahepatic cholangiocarcinoma (iCCA) is poorly understood, and its incidence continues to increase worldwide. Deficiency of mitogen-activated protein kinase kinase kinase 4 (MAP3K4) has been reported to induce the epithelial-mesenchymal transition (EMT) process of placental and embryonic development, yet its role in human cancer remains unknown. MAP3K4 has somatic mutation in iCCA so we sequenced all exons of MAP3K4 in 124 iCCA patients.

Unlabelled: Hepatocellular carcinoma (HCC) is the third-most lethal cancer worldwide. Understanding the molecular pathogenesis of HCC recurrence and metastasis is the key to improve patients' prognosis. In this study, we report that protein tyrosine phosphatase receptor S (PTPRS) is significantly down-regulated in nearly 80% of HCCs, and its expression negatively correlates with aggressive pathological features, such as larger tumor size and advanced stage.

L-Cysteine plays a prominent role in sulfur metabolism of plants. However, its role in root development is largely unknown. Here, we report that L-cysteine reduces primary root growth in a dosage-dependent manner.

Background & Aims: The pathogenesis of intrahepatic cholangiocarcinoma (ICC), the second most common hepatic cancer, is poorly understood, and the incidence of ICC is increasing worldwide. We searched for mutations in human ICC tumor samples and investigated how they affect ICC cell function.

Methods: We performed whole exome sequencing of 7 pairs of ICC tumors and their surrounding nontumor tissues to detect somatic alterations.

As an ancient arthropod with a history of 390 million years, spiders evolved numerous morphological forms resulting from adaptation to different environments. The venom and silk of spiders, which have promising commercial applications in agriculture, medicine and engineering fields, are of special interests to researchers. However, little is known about their genomic components, which hinders not only understanding spider biology but also utilizing their valuable genes.

CXC chemokines and their cognate receptors have been implicated widely in cancer pathogenesis. In this study, we report a critical causal relationship between CXCR6 expression and tumorigenesis in the setting of human hepatocellular carcinoma (HCC). Among the CXC chemokine receptors, only CXCR6 was detected in all the hepatoma cell lines studied.

Aim: To investigate whether mitochondria permeability transition pore (mPTP) opening was involved in ginsenoside Rb1 (Gs-Rb1) induced anti-hypoxia effects in neonatal rat cardiomyocytes ex vivo.

Methods: Cardiomyocytes were randomly divided into 7 groups: control group, hypoxia group (500 micromol/L CoCl(2)), Gs-Rb1 200 micromol/L group (CoCl(2) intervention+Gs-Rb1), wortmannin (PI3K inhibitor) 0.5 micromol/L group, wortmannin+Gs-Rb1 group, adenine 9-beta-D-arabinofuranoside (Ara A, AMPK inhibitor) 500 micromol/L group, and Ara A and Gs-Rb1 group.

It is very important to disrupt the stratum corneum structure and to create pathways allowing transport of macromolecules, as the traditional transdermal drug delivery has been severely limited by the skin barrier. With the development of the Micro Electro-Mechanical System (MEMS), it becomes possible for microneedles array to strengthen the transdermal drug delivery. In addition to the increase of the skin permeability, it can also be used to deliver drugs into skin, such as insulin and vaccine, providing a new direction for drug delivery systems.

To understand the DNA-methylation mediated gene silencing mechanisms, we analyzed in cell culture of the promoter function of the MAGE-A1 gene, which is frequently demethylated and over-expressed in human hepatocellular carcinoma. We have established the correlation of the DNA methylation of the promoter CpG island with expression status of this gene in a panel of the established liver cancer cell lines. The crucial CpG dinucleotide(s) within the minimal promoter subjected to the control mediated by DNA methylation with profound biological functions was also delineated.
