Complexities at the Au/ZrS(001) interface probed by X-ray photoemission spectroscopy.

J Phys Condens Matter 2021 Jul 22. Epub 2021 Jul 22.

Department of Physics and Astronomy and Center for Materials Research and Analysis, University of Nebraska- Lincoln, Jorgensen Hall, 855 North 16th Str., NE 68588-0299, Lincoln, 68588-0299, UNITED STATES.

Interaction between the Au adlayers and ZrS(001) has been examined via X-ray photoemission spectroscopy (XPS). The angle-resolved XPS (ARXPS) measurements reveal that ZrS(001) is disulfide (S) terminated and the Au thickness-dependent XPS indicates that the observed band bending, for low Au coverage, is consistent with formation of a Schottky barrier at the Au/ZrS(001) interface. This band bending, however, appears to be suppressed as the thickness of Au adlayer is increased, indicating varying interfacial interactions at the Au/ZrS(001) interface. Read More

Review: The development of the gastrointestinal tract microbiota and intervention in neonatal ruminants.

Animal 2021 Jul 19;15(8):100316. Epub 2021 Jul 19.

Department of Animal Science, College of Animal Sciences, Jilin University, Changchun 130062, China. Electronic address:

The complex microbiome colonizing the gastrointestinal tract (GIT) of ruminants plays an important role in the development of the immune system, nutrient absorption and metabolism. Hence, understanding GIT microbiota colonization in neonatal ruminants has positive impacts on host health and productivity. Microbes rapidly colonize the GIT after birth and gradually develop into a complex microbial community, which allows the possibility of GIT microbiome manipulation to enhance newborn health and growth and perhaps induce lasting effects in adult ruminants.

The complex interplay of gut microbiota with the five most common cancer types: From carcinogenesis to therapeutics to prognosis.

Crit Rev Oncol Hematol 2021 Jul 19:103429. Epub 2021 Jul 19.

NICM Health Research Institute, Western Sydney University, Penrith, NSW 2747, Australia. Electronic address:

The association between human gut microbiota and cancers has been an evolving field of biomedical research in recent years. The gut microbiota is composed of the microorganisms residing in the gastrointestinal system that interact with the host to regulate behaviours and biochemical processes within the gut. This symbiotic physiological interaction between the gut and the microbiota plays a significant role in the modulation of gut homeostasis, in which perturbations to the microbiota, also known as dysbiosis can lead to the onset of diseases, including cancer.

Toxicol In Vitro 2021 Jul 19:105227. Epub 2021 Jul 19.

Department of Neurology, University of Chinese Academy of Sciences Shenzhen Hospital (Guang ming), No. 39 Huaxia Road, Guangming District, Shenzhen 518107, China. Electronic address:

Lysophosphatidylcholine (LPC), as the main active component of oxidized low-density lipoproteins (ox-LDLs), has significant effects in cerebrovascular disease. However, the complex mechanism by which LPC functions in brain microvascular endothelial cells (BMECs) is not clearly understood. In this study, BMECs were transfected with G protein-coupled receptor 4 (GPR4) siRNA or an NLRP3-overexpression plasmid, and GPR4 expression was identified by RT-qPCR and western blotting; IL-1β, IL-18, and IL-33 levels were evaluated by ELISA.

The functional cross talk between cancer cells and cancer associated fibroblasts from a cancer mechanics perspective.

Biochim Biophys Acta Mol Cell Res 2021 Jul 19:119103. Epub 2021 Jul 19.

Faculty of Biomedical Engineering, Amirkabir University of Technology, Tehran, Iran. Electronic address:

The function of biological tissues in health and disease is regulated at cellular level and is highly influenced by the physical microenvironment, through the interaction of forces between cells and ECM, which are perceived through mechanosensing pathways. In cancer, both chemical and physical signaling cascades and their interactions are involved during cell-cell and cell-ECM communications to meet requirements of tumor growth. Among stroma cells, cancer associated fibroblasts (CAFs) play key role in tumor growth and pave the way for cancer cells to initiate metastasis and invasion to other tissues, and without recruitment of CAFs, the process of cancer invasion is dysfunctional.
