BACKGROUND Tacrolimus extended-release tablets have been Food and Drug Administrationapproved for use in the de novo kidney transplant *** requirements often vary for tacrolimus based on several factors including variation in metabolism based on CYP3A5 *** who express CYP3A5 often require higher dosing of immediate-release tacrolimus,but this has not been established for tacrolimus extended-release tablets in the de novo *** To obtain target trough concentrations of extended-release tacrolimus in de novo kidney transplant recipients according to CYP3A5 *** Single-arm,prospective,single-center,open-label,observational study(***:NCT037-13645).Life cycle pharma tacrolimus(LCPT)orally once daily at a starting dose of 0.13 mg/kg/day based on actual body *** weight is more than 120%of ideal body weight,an adjusted body weight was *** dose was adjusted to maintain tacrolimus trough concentrations of 8-10 ng/*** analysis of CYP3A5 genotype was performed at study *** Mean time to therapeutic tacrolimus trough concentration was longer in CYP3A5 intermediate and extensive metabolizers vs CYP3A5 non-expressers(6 d vs 13.5 d vs 4.5 d;P=0.025).Mean tacrolimus doses and weight-based doses to achieve therapeutic concentration were higher in CYP3A5 intermediate and extensive metabolizers vs CYP3A5 non-expressers(16 mg vs 16 mg vs 12 mg;P=0.010)(0.20 mg/kg vs 0.19 mg/kg vs 0.13 mg/kg;P=0.018).CYP3A5 extensive metabolizers experienced lower mean tacrolimus trough concentrations throughout the study period compared to CYP3A5 intermediate metabolizers and non-expressers(7.98 ng/mL vs 9.18 ng/mL vs 10.78 ng/mL;P=00.008).No differences were identified with regards to kidney graft function at 30-d *** adverse events were reported for 13(36%)*** Expression of CYP3A5 leads to higher starting doses and incremental dosage titration of extended-release

Output feedback adaptive super twisting sliding mode control for quadrotor UAVs

Control Theory and Technology 2024年第1期22卷 92-105页

作者： oscar Salas-Peña Jesus DeLeón-Morales Susana V.Gutiérrez-Martínez École Centrale de Nantes-LS2N UMR 6004 CNRS44300NantesFrance Facultad de Ingeniería Mecánica y Eléctrica Universidad Autónoma de Nuevo León66451San Nicolás de Los GarzaMexico

In this paper, a sliding mode control with adaptive gain combined with a high-order sliding mode observer to solve the tracking problem for a quadrotor UAV is addressed, in presence of bounded external disturbances and parametric uncertainties. The high order sliding mode observer is designed for estimating the linear and angular speed in order to implement the proposed scheme. Furthermore, a Lyapunov function is introduced to design the controller with the adaptation law, whereas an analysis of finite time convergence towards to zero is provided, where sufficient conditions are obtained. Regarding previous works from literature, one important advantage of proposed strategy is that the gains of control are parameterized in terms of only one adaptive parameter, which reduces the control effort by avoiding gain overestimation. Numerical simulations for tracking control of the quadrotor are given to show the performance of proposed adaptive control–observer scheme.

Purpose:To examine the effects of a school-based karate intervention on academic achievement,psychosocial functioning,and physical fitness in children aged 7-8 ***:Twenty schools in 5 different European countries(2 second-grade classrooms per school)participated in a cluster randomized controlled trial(Sport at School trial).Participants were assigned to either a control group,which continued with their habitual physical education lessons,or to an intervention group,which replaced these lessons with a 1-year karate intervention(Karate Mind and Movement program).A total of 721 children(344 girls and 377 boys,7.4±0.5 years old,mean±SD)completed the study,of which 333 and 388 were assigned to the control group and intervention group,*** included academic performance(average grade),psychosocial functioning(Strengths and Difficulties Questionnaire for parents),and different markers of physical fitness(cardiorespiratory fitness,balance,and flexibility).Results:The intervention provided small but significant benefits compared to the control group for academic achievement(d=0.16;p=0.003),conduct problems(d=-0.28;p=0.003),cardiorespiratory fitness(d=0.36;p0.05).Conclusion:A 1-year school-based karate intervention was effective in improving academic achievement,conduct problems,and physical fitness in primary school *** results support the inclusion of karate during physical education lessons.
