preservative-free mixture of water and propylene glycol; pH of 3.5 to 5.0 achieved by the addition of a concentrated strong acid; can be nebulised with currently available nebulisersdoi:US6967017 B1The present invention relates to optimized formulations of antiinflammatory steroids for nebulisation ...
Acids are divided into those which ionize to a major extent (strong acids) and those which are largely unionized (weak acids). Most acids encountered in living tissues belong to the latter group. The extent of ionization can be assessed in terms of the equilibrium constant of reaction (3):...
However, in the combination of the two processes, 85% of this compound was removed after 191 h. The degradation of 2,4-DCPh was enhanced from 40 to 87%. The presence of organics acids and the remaining phenolic compounds still represent an important treatment challenge. The mixture of ...
(black) amino acids (Supplementary Table1), H2, and N2O. TheDesulfosporosinussp. cell numbers (red diamonds) were determined with 16S rRNA gene-targeted qPCR and show growth in medium receiving the 15-amino acid mixture. Various other amino acid mixtures tested resulted in no or negligible ...
Spatial proton gradients create energy in biological systems and are likely a driving force for prebiotic systems. Due to the fast diffusion of protons, they are however difficult to create as steady state, unless driven by other non-equilibria such as t
X-ray diffraction (XRD) was used to further verify the structure of αCT/ Res-JNPs, and it was found that compared with the drug/ polymer physical mixture, the derivative peaks of αCT and Res disappeared in the XRD spectra of αCT/Res- JNP lyophilized powder (Fig. 1C), ...
It remains unclear whether the suppression of UFAs synthesis or FnfabM gene enhances bacterial sensitivity to strong acids. Therefore, in vitro and in vivo experiments were performed to determine the sensitivity of these cells to acids after suppression. Cerulenin at a concentration of 30 μg/...
In the area of polymer additives, Ciba Geigy’s Irganox HP-136 327 is produced as a 9:1 mixture of isomers. Irganox is a widely used nonphenolic phthalide which acts as a radical scavenger that often works in concert with other antioxidants such as IRGAFOS, a phosphorus-based compound <200...
The practical application of nanoparticles (NPs) as chemotherapeutic drug delivery systems is often hampered by issues such as poor circulation stability and targeting inefficiency. Here, we have utilized a simple approach to prepare biocompatible and bi
