Effect of saliva stimulants (Hybrin and malic acid) on cervical root surfaces in vitro.

G Anneroth et al.

Scandinavian journal of dental research, 88(3), 214-218 (1980-06-01)

Two saliva stimulating drugs, solutions of Hybrin and malic acid were in an in vitro study found to have a heavy demineralizing effect on the root surface of the dental hard tissue. Consequently the drugs cannot be recommended to patients

Investigation of malic acid production in Aspergillus oryzae under nitrogen starvation conditions.

Christoph Knuf et al.

Applied and environmental microbiology, 79(19), 6050-6058 (2013-07-31)

Malic acid has great potential for replacing petrochemical building blocks in the future. For this application, high yields, rates, and titers are essential in order to sustain a viable biotechnological production process. Natural high-capacity malic acid producers like the malic

Reactive oxygen species are generated by the respiratory complex II--evidence for lack of contribution of the reverse electron flow in complex I.

Rafael Moreno-Sánchez et al.

The FEBS journal, 280(3), 927-938 (2012-12-05)

Succinate-driven oxidation via complex II (CII) may have a significant contribution towards the high rates of production of reactive oxygen species (ROS) by mitochondria. Here, we show that the CII Q site inhibitor thenoyltrifluoroacetone (TTFA) blocks succinate + rotenone-driven ROS

A thermostable Salmonella phage endolysin, Lys68, with broad bactericidal properties against gram-negative pathogens in presence of weak acids.

Hugo Oliveira et al.

PloS one, 9(10), e108376-e108376 (2014-10-08)

Resistance rates are increasing among several problematic Gram-negative pathogens, a fact that has encouraged the development of new antimicrobial agents. This paper characterizes a Salmonella phage endolysin (Lys68) and demonstrates its potential antimicrobial effectiveness when combined with organic acids towards

Alterations in cellular energy metabolism associated with the antiproliferative effects of the ATM inhibitor KU-55933 and with metformin.

Mahvash Zakikhani et al.

PloS one, 7(11), e49513-e49513 (2012-11-28)

KU-55933 is a specific inhibitor of the kinase activity of the protein encoded by Ataxia telangiectasia mutated (ATM), an important tumor suppressor gene with key roles in DNA repair. Unexpectedly for an inhibitor of a tumor suppressor gene, KU-55933 reduces
