CRISPR/Cas-Based Biosensor As a New Age Detection Method for Pathogenic Bacteria.

Methods enabling rapid and on-site detection of pathogenic bacteria are a prerequisite for public health assurance, medical diagnostics, ensuring food safety and security, and research. Many current bacteria detection technologies are inconvenient and time-consuming, making them unsuitable for field detection. New technology based on the CRISPR/Cas system has the potential to fill the existing gaps in detection.

Biosynthesized CdS Nanoparticle Induces ROS-dependent Apoptosis in Human Lung Cancer Cells.

Background: The World Health Organization (WHO) estimated that the number of cancer-related deaths was 9.6 million in 2018 and 2.09 million deaths occurred by lung cancer.

Angiotensin II inhibits Na+/K+ATPase activity in pulmonary artery smooth muscle cells via glutathionylation and with the involvement of a 15.6 kDa inhibitor protein.

The role of angiotensin II in regulating Na+/K(+)-ATPase activity has been investigated in bovine pulmonary artery smooth muscle cells (BPASMCs). Our study reveals that angiotensin II inhibits the Na+/K+ATPase activity via glutathionylation of the pump with the involvement of an increase in NADPH oxidase-derived O2*-. Additionally, angiotensin II treatment to the cells increases the inhibitory potency of the 15.

Role of phospholemman and the 70 kDa inhibitor protein in regulating Na+/K+ ATPase activity in pulmonary artery smooth muscle cells under U46619 stimulation.

Treatment of bovine pulmonary smooth muscle cells with U46619 inhibited the Na(+)/K(+) ATPase activity in two parallel pathways: one of which is mediated via glutathionylation of the pump and the other by augmenting the inhibitory activity of the 70kDa inhibitor protein of Na(+)/K(+) ATPase. Although phospholemman deglutathionylates the pump leading to its activation, the inhibitor is responsible for irreversible inhibition of Na(+)/K(+) ATPase in an isoform specific manner during treatment of the cells with U46619.
