Van Berkel; Pimchai Chaiyen; Chulalongkorn University; Mahidol University; Wageningen University and Research CentreBackground: 3-Hydroxybenzoate 6-hydroxylase (3HB6H) is a flavoprotein hydroxylase catalyzing the para-hydroxylation of 3-hydroxybenzoate. Results: The oxidative half-reaction was studied using transient kinetics. The enzyme reaction mechanismItem Metadata only Kinetic mechanisms of electron bifurcation with electron transfer flavoprotein, NADH, butyryl-CoA dehydrogenase, and ferredoxin reveal a semiquinone cycle(2025-10-01) Sucharitakul J.; Mangkalee M.; Intasian P.; Pornsuwan S.; Ermler U.; Buckel W.; Chaiyen P.; Sucharitakul J.; Mahidol University) and high potential crotonyl-CoA using NADH as an electron donor. Our previous rapid kinetic studies have demonstrated “pseudo-electron bifurcation” where NADH and two EtfAB molecules generate EtfASQB (ASQ contains α-FAD•−cycle, which we call the semiquinone cycle of electron bifurcation, because it starts and ends with a semiquinone.Item Metadata only Development of a bromoperoxidase-based learning cycle to enhance conceptual understanding of second year university students concerning enzyme kinetics(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Piyachat Jittam; Pintip RuenwongsaItem Metadata only A chemically tunable FOXM1-DHFR sensor reveals the direct influence of FOXM1 on the cell cycle(2025-07-15) Phongkitkarun K.; Chusorn P.; Kamkaew M.; Jamnongsong S.; Lam E.W.F.; Promptmas C.; Sampattavanich S.; Phongkitkarun K.; Mahidol Universitythe first division, whereas those with timely degradation could undergo a second division. Sustained FOXM1-D overexpression induced cell cycle arrest in daughter cells, highlighting the role of FOXM1 kinetics in determining cell fate. Sustained FOXM1-D... cycle remains unclear. We developed a tunable FOXM1-dihydrofolate reductase (DHFR) sensor, FOXM1-D, in non-malignant MCF10A cells, enabling real-time monitoring and manipulation of FOXM1 levels. Using trimethoprim to stabilize FOXM1-D, we quantified itsPublication Metadata only Modelling effects of high product and substrate inhibition on oscillatory behavior in continuous bioreactors(1999-03-01) Yongwimon Lenbury; Apichat Neamvong; Somkid Amornsamankul; Pannee Puttapiban; Mahidol Universityand the growing microorganisms can give rise to high frequency oscillations which can arise during the transients toward the attractor or during the low-frequency cycle. Such a study not only can describe more fully the kinetics in a fermenter but also assist...In this study we consider a model for continuous bioreactors which incorporates the effects of high product and substrate inhibition on the kinetics as well as biomass and product yields. We theoretically investigate the possibility of variousPublication Metadata only Modeling insulin kinetics: Responses to a single oral glucose administration or ambulatory-fed conditions(2001-02-27) Yongwimon Lenbury; Sitipong Ruktamatakul; Somkid Amornsamarnkul; Mahidol Universityis carried out by the singular perturbation technique in order to derive boundary conditions on the system parameters which identify, in particular, the existence of limit cycles in our model system consistent with the oscillatory patterns often observedItem Metadata only Evaluating the performance and kinetics of amine-modified NaY zeolites from rice husk for direct air CO2 capture(2025-06-01) Nokpho P.; Phianchana K.; Wang X.; Boonprasop S.; Piumsomboon P.; Chalermsinsuwan B.; Nokpho P.; Mahidol Universityto enhance direct air CO2 capture performance. 30 wt% MEA/NaY sorbent exhibited the highest CO2 uptake, achieving approximately 14.5 mgCO2/g at 30 °C. Sorbent retained about 96 percent of its initial capacity after ten cycles. Kinetic analysis using AvramiItem Metadata only Knee Kinetics and Kinematics during Ten-Sao Dance: A Comparison between Khon Masked Dancers and Non-dancers(2023-01-01) Jearudomsup P.; Bovonsunthonchai S.; Vachalathiti R.; Piriyaprasarth P.; Krityakiarana W.; Jearudomsup P.; Mahidol Universityhealthy males, including Khon masked dancers (n = 10) and non-dancers (n = 10) participated in the study. All participants performed Ten-Sao 10 cycles, then the kinetics and kinematics of starting and leg rising phases were investigated using 3D motion... the performance. The excessive knee flexion and varus position could exhibit an impact force and stress on the knee structures and leads to knee injury risk.
