AIM Evaluation of a peak at 3.55 ppm in a long echo time (TE) recognized as glycine (Gly) in the WHO grade II gliomas and central neurocytomas by means of 1H MRS. MATERIAL AND METHODS Retrospective analysis of 19 patients with histopathologically confirmed WHO grade II glioma and 2 patients with central neurocytoma was conducted. 1H MRS (TE = 135 ms and TE = 144 ms) was performed with 1.5 T a...
Mutants of lactose permease of Escherichia coli with amino acid changes (Gly-24----Glu; Gly-24----Arg; Pro-28---Ser; Gly-24, Pro-28----Glu-Ser and Gly-24, Pro-28----Arg-Ser) within a putative membrane-spanning alpha-helix (Phe-Gly-Leu-Phe-Phe-Phe-Phe-Tyr-Phe-Phe-Ile-Met-Gly- Ala-Tyr-Phe-Pro-Phe-Phe-Pro-Ile) are incorporated into the cytoplasmic membrane. The mutant proteins retain the ability t...
We presented a strategy for fabricating graphene oxide (GO)-based fluorescent biosensors to monitor the change of phosphorylation state and detect phosphatase activity. By regulating the interaction between the negatively charged phosphate group and the positively charged amino residue, we found that GO showed different quenching efficiency toward the phosphorylated and dephosphorylated dye-lab...
Gas-phase complexes [La(peptide)](3+) containing 2-4 amino-acid residues have been investigated by electrospraying solutions containing La(3+) and the peptide; only complexes in which the peptide contained an arginine residue were observed. Using the coordination number of eight for La(3+) [Shi, T.; Hopkinson, A. C.; Siu, K. W. M. Chem. Eur. J. 2007, 13, 1142-1151] and the relative abundances o...
The studied hypothesis is that the herbicide glyphosate (GLY) can affect oxidative balance in hydrophobic intracellular medium non-target Chlorella vulgaris cells. Analytical GLY and RoundUp (RUP) supplementation, affected growth profile. A significant 42% decrease cellular biomass stationary (St) phase was observed cultures supplemented with either 5 µM of or RUP, as compared to control cultur...
The three-dimensional structures of two common repeat motifs Val-Pro-Gly-Val-Gly and ValGly-Val-Pro-Gly-Val-Gly-Val-Pro of tropoelastin are investigated by using the multicanonical simulation procedure. By minimizing the energy structures along the trajectory the thermodynamically most stable low-energy microstates of the molecule are determined. The structural predictions are in good agreement...
BACKGROUND The optimal use of various therapeutic combinations for moderate/severe chronic obstructive pulmonary disease (COPD) is unclear. The GLISTEN trial compared the efficacy of two long-acting anti-muscarinic antagonists (LAMA), when combined with an inhaled corticosteroid (ICS) and a long-acting β2 agonist (LABA). METHODS This randomised, blinded, placebo-controlled trial in moderate/s...
