“…METHODS: This randomized double-blinded clinical trial was performed on 60 women who suffered from melasma and were referred to the skin disorders clinic at the Rasoul-e-Akram hospital in Tehran in 2015. The patients were then randomly assigned via computerized randomization to two groups: group A received TXA%5 (topically twice a day for 12 weeks in the location of the melasma) and group B (received hydroquinone 2% with the same treatment order). …”

“…Our experimental results in HeLa cells expressing Cx36 show that changes in both pH(i) and [Mg(2+)](i) affect junctional conductance (g(j)) in an interdependent manner; in other words, intracellular acidification cause increase or decay in g(j) depending on whether [Mg(2+)](i) is high or low, respectively, and intracellular alkalization cause reduction in g(j) independently of [Mg(2+)](i). …”

“…We compared several semi-quantitative methods: external calibration curves generated in the sampling system and by liquid addition of standards to stir bars, total integrated peak area per fresh weight (FW), normalized peak area per FW, semi-quantification based on internal standard abundance, semi-quantification based on the nearest n-alkane and percentage of emission. Furthermore, we explored the usage of nearest components and single calibrators for semi-quantifications. …”
