Connexin43 mimetic peptide （Cx43MP） has been intensively investigated for its therapeutic effect in the management of inflammatory eye conditions, spinal cord injury, wound healing and iscbemia-induced brain damage. Here, we report on a validated stability-indicating reversed-phase high performance liquid chromatography （RP-HPLC） method for the quantification of Cx43MP under stress conditions. These included exposure to acid/base, light, oxidation and high temperature. In addition, the degradation kinetics of the peptide were evaluated in bovine vitreous and drug-free human plasma at 37℃. Detection of Cx43MP was carried out at 214 nm with a retention time of 7.5 min. The method showed excellent linearity over the concentration range of 0.9-250μg/mL （R2a0.998）, and the limits of detection （LOD） and quantification （LOQ） were found to be 0.90 and 2.98 μg/mL, respectively. The accuracy of the method determined by the mean percentage recovery at 7.8, 62.5 and 250μg/mL was 96.79%, 98.25% and 99.06% with a RSD of〈 2.2%. Accelerated stability studies revealed that Cx43MP was more sensitive to basic conditions and completely degraded within 24 h at 37℃（0% recovery） and within 12 h at 80℃ （0.34% recovery）. Cx43MP was found to be more stable in bovine vitreous （t1/2 slow= 171.8 min） compared to human plasma （t1/2slow = 39.3 min） at 37℃ according to the two phase degradation kinetic model. These findings are important for further pre-clinical development of Cx43MP.

This paper proposes a novel transmission use of system(TUoS)charging method,which is able to 1)acknowledge the trade-offs between short-run congestion cost and long-run investment cost when justifying economic network investment,2)identify the impacts of different generation technologies on congestion cost and network investment,and 3)translate these impacts into economically efficient TUoS tariffs that differentiate generation *** incremental capacity change from a generator will impact the congestion costs at each branch,which is then translated into the impacts on investment time *** difference in the present values with and without the incremental change for a branch is its long-run incremental cost(LRIC).The final TUoS tariff for this generator is the sum of all LRIC triggered by its capacity *** proposed method is demonstrated on a modified IEEE 14-bus system to show its effectiveness over the traditional *** show that it can provide cost-reflective TUoS tariffs for different generation technologies at the same sites by examining their respective impacts on congestion and *** thus can incentivize appropriate generation expansion to reduce congestion costs and ultimately network investment cost.
