Liquid Chromatography-Tandem Mass Spectrometric Determination of Geniposide in Rat Plasma and its Pharmacokinetic Application

Ming Ji Jin,In Sook Kim,김동현,유혜현 대한화학회 2013 Bulletin of the Korean Chemical Society Vol.34 No.9

Geniposide is a biologically active ingredient of gardenia fruit. A liquid chromatography-tandem mass spectrometric method was developed and validated for the determination of geniposide in rat plasma. The plasma samples were pretreated by solid-phase extraction and introduced into a BDS Hypersil C18 column (50 × 2.1 mm, 5 μm) for chromatographic separation. The mobile phase consisted of 0.1% formic acid and 0.1% formic acid in acetonitrile, and gradient elution was performed at a flow rate of 0.25 mL/min. For mass spectrometric detection, multiple reaction monitoring was performed via an electrospray ionization source in positive mode. The calibration curve for geniposide was linear (r2 = 0.997) in the concentration range of 0.005- 1 μg/mL. The intra- and inter-day accuracies and precisions fulfilled the required criteria (± 15%). The developed method was subsequently used for pharmacokinetic analysis of geniposide after oral administration to rats at a dose of 50 mg/kg. The mean maximum plasma concentration of geniposide was 0.68 ± 0.29 μg/mL at 0.44 ± 0.13 h, and the mean area under the plasma concentration versus time curve was 1.46 μg·h/mL.

Ming Jin,Ji Young Kim,Ji Hyun Sung,Tae Hee Kim,Doo Kyung Kang,Se Hwan Han,Yong Sik Jung 한국유방암학회 2020 Journal of Breast Disease Vol.8 No.1

Purpose: Neoadjuvant chemotherapy (NAC) can effectively downstage locally advanced breast cancer; however, in some cases the cancer remains clinically stable and in others, there is disease progression. Although factors predictive of the response to NAC have been established, those for a non-response remain unknown. This study investigated factors predicting a stable or progressive disease course, and the extent of the response, after NAC based on anthracycline and cyclophosphamide (AC), with or without taxane. Methods: Data were collected retrospectively by reviewing medical records of patients who received NAC for breast cancer using AC, with or without taxane between January 2013 and December 2017. Patients with clinically stable or progressive disease after NAC were compared statistically with those who achieved a partial or complete response. Results: In total, 297 patients received NAC with AC and 196 patients received AC followed by taxane. Of these, 45 (15.2%) and 64 (32.6%) patients respectively, showed no response (i.e., stable or progressive disease). Factors related to non-response after AC included large pretreatment tumor size, clinical T3 status, and high histologic grade. Factors related to non-response after taxane included clinical T3 status and estrogen receptor or progesterone receptor positivity. Conclusion: Clinical T3 stage, grade III histological grade, and estrogen or progesterone receptor positivity were predictors of no response to NAC for breast cancer.

Memory Event-triggered Sliding Mode Control for UAV Formation Under Communication Delay and Wake Interferences

Ming-Fei Ji,Tao Li,Shu-Min Fei,Xian-Lin Zhao 제어·로봇·시스템학회 2024 International Journal of Control, Automation, and Vol.22 No.3

This paper studies the formation control for unmanned aerial vehicles (UAVs) under communicationdelay and wake disturbances, in which the inner-loop and outer-loop control strategy is adopted. Firstly, as for thedynamical models of follower UAVs, the wake interferences are considered and their influences are respectivelyestimated by using the sliding model disturbance observers (SMDOs). Secondly, since the outer-loop informationin the UAVs exchanges via communication network, by adding an internal dynamic variable, an adaptive memorybased event-triggered mechanism (METM) is proposed to alleviate transmission burden with maintaining idealcontrol performance. Thirdly, by using the designed METM and an intermediate vector, a sliding mode controller isderived to accomplish the desired control target, which can compensate the communication delay in control input. Fourthly, as for the overall closed-loop system, a sufficient condition on asymptotical stability is established and aco-design method of checking the triggering parameters and controller gains is expressed in term of linear matrixinequalities (LMIs). Moreover, in order to tackle the wake interferences of the inner-loop, an adaptive attitudetracking controller is put forward to ensure the bounded stability of tracking errors by solving the reference signal. Finally, a simulated example is exploited to illustrate the validity of the proposed scheme.

Ming Ji Jin,서기수,하일호,한효경 대한약학회 2008 Archives of Pharmacal Research Vol.31 No.7

A high-performance liquid chromatographic method was developed for the determination of macelignan in rat plasma and applied to the pharmacokinetic study of macelignan in rats. Chromatographic separation was achieved on a conventional ODS column with the mobile phase of water: acetonitrile: methanol = 35:32.5:32.5 (v/v/v %). The flow rate of isocratic elution was 1 mL/min and peaks were detected at 240 nm. The limit of detection was 10 ng/mL and the limit of quantitation was 20 ng/mL. The calibration curve was linear over the concentration range of 50-5000 ng/mL. Intra-and inter-day precision for the assay over the concentration range was below 10 % and the accuracy ranged between 96.0-107% for intra-day and 98.8-114% for inter-day, respectively. The method was applied to the single dose pharmacokinetic study of macelignan in rats and the results showed that this HPLC method was adequate to support the in vivo pharmacokinetic study of macelignan.

본 연구는 영세한 소규모 업체에서도 적은 비용부담으로 사용할 수 있는 오 · 폐수처리장치 개발이 필요한 실정에 맞추어 자연포기형 생물막공정을 이용한 난분해성물질을 포함한 고농도 화학산업 폐수의 유기물 용적부하와 수리학적부하에 따른 처리효율 분석을 통하여 자연포기형 생물막공정의 난분해성물질을 포함한 고농도 폐수 처리 효율성을 분석하고자 한다. 유기물 용적부하 0.2kg COD_Mn/㎥/d, 0.47kg COD_Mn/㎥/d, 0.78kg COD_Mn/㎥/d인 저율, 중율, 고율 살수여상의 운전범위에서 실험을 수행한 결과 유기물 용적부하 0.2kg COD_Mn/㎥/d, 0.47kg COD_Mn/㎥/d인 저율, 중율 살수여상의 운전범위에서 BOD₅, COD_Mn, COD_Cr 처리효율 모두 살수여상의 설계기준을 만족하며 안정적인 처리를 진행하였으나, 유기물 용적부하 0.78kg COD_Mn/㎥/d인 고율 살수여상의 운전범위에서 COD_Mn과 COD_Cr 처리효율은 설계기준에 다소 못 미치는 결과를 나타냈다. 수리학적부하 6.3㎥/㎡/d, 20.1㎥/㎡/d, 33.4㎥/㎡/d인 중속, 고속, 고속 살수여상의 수리학적부하 운전범위에서 실험을 수행한 결과 모든 운전조건에서 SS와 BOD5는 수리학적부하의 영향을 받지 않았으며, COD_Mn과 COD_Cr은 수리학적부하가 증가함에 따라 처리효율도 다소 증가하였으나 큰 영향은 받지 않았다. 따라서 경제적/효율적인 면을 동시에 만족시키기 위한 유기물 용적부하와 수리학적부하로 중율과 중속 살수여상의 운전범위에서 운전하는 것이 적정하다. In this study, natural aeration biofilm process was employed according to the requirement of development low cost-energy treatment equipment for small corporation. The efficiency of this equipment was evaluated at different organic loading rate and hydraulic loading rate to treat chemical wastewater which contains non-biodegradable matters. The chemical wastewater was treated under a trickling filter of organic loading rate at 0.2kgCOD_Mn/㎥/d, 0.47kgCOD_Mn/㎥/d and 0.78kg COD_Mn/㎥/d. when the organic loading rate is at low-rate of 0.2kg COD_Mn/㎥/d and intermediate-rate of 0.47kg COD_Mn/㎥/d, the removal efficiency of BOD₅, COD_Mn and COD_Cr can satisfied the design standard of general trickling filter process and the wastewater can be treated stably. However, when the organic loading rate is at high-rate of 0.78kg COD_Mn/㎥/d, removal efficiency of COD_Mn and COD_Cr can not satisfied the design standard of general trickling filter process. When the wastewater was treated at hydraulic loading rate of 6.3㎥/㎡/d, 20.1㎥/㎡/d and 33.4 ㎥/㎡/d, the removal efficiencies of SS and BOD₅ didn`t effected by hydraulic loading rate. While the removal efficiencies of COD_Mn and COD_Cr were increased by the increasing of by hydraulic loading rate, but the efficiencies were not distinct. To sum up, at the intermediate-rate of trickling filter, the effect of chemical wastewater treatment can be the economical and effective.
