Pma1 is an alkali/alkaline earth metal cation ATPase that preferentially transports Na(+) and K(+) across the Mycobacterium smegmatis plasma membrane.

Carlos Ayala-Torres et al.

Microbiological research, 176, 1-6 (2015-06-14)

Mycobacterium smegmatis Pma1 is the orthologue of M. tuberculosis P-type ATPase cation transporter CtpF, which is activated under stress conditions, such as hypoxia, starvation and response to antituberculous and toxic substances. The function of Pma1 in the mycobacterial processes across

Solid-phase extraction of galloyl- and caffeoylquinic acids from natural sources (Galphimia glauca and Arnicae flos) using pure zirconium silicate and bismuth citrate powders as sorbents inside micro spin columns.

Shah Hussain et al.

Journal of pharmaceutical and biomedical analysis, 84, 148-158 (2013-07-09)

Galloyl- and caffeoylquinic acids are among the most important pharmacological active groups of natural compounds. This study describes a pre-step in isolation of some selected representatives of these groups from biological samples. A selective solid-phase extraction (SPE) method for these

Fabrication of bismuth subcarbonate nanotube arrays from bismuth citrate.

Rong Chen et al.

Chemical communications (Cambridge, England), (21)(21), 2265-2267 (2006-05-24)

Bismuth subcarbonate ((BiO)2CO3) nanotubes with uniform diameters of about 3-5 nm were fabricated from bismuth citrate; these nanotubes exhibit antibacterial properties against Helicobacter pylori (50% inhibition at 10 microg mL(-1)), a bacterium causing peptic ulcers and gastritis.

Disposable integrated bismuth citrate-modified screen-printed immunosensor for ultrasensitive quantum dot-based electrochemical assay of C-reactive protein in human serum.

Christos Kokkinos et al.

Analytica chimica acta, 886, 29-36 (2015-09-01)

A novel immunosensor based on graphite screen-printed electrodes (SPEs) modified with bismuth citrate was developed for the voltammetric determination of C-reactive protein (CRP) in human serum using quantum dots (QDs) labels. The sandwich-type immunoassay involved physisorption of CRP capture antibody

Targeting PTEN using small molecule inhibitors.

Lok Hang Mak et al.

Methods (San Diego, Calif.), 77-78, 63-68 (2015-03-10)

PTEN (phosphatase and tensin homologue deleted on chromosome 10) is well known as a tumour suppressor. It's PI(3,4,5)P3 lipid phosphatase activity is an important counteracting mechanism in PI 3-kinase (phosphoinositide 3-kinase) signalling. Furthermore, PTEN lies upstream of Akt kinase, a
