3D Printing Hip Prostheses Offer Accurate Reconstruction, Stable Fixation, and Functional Recovery forRevision Total Hip Arthroplasty with Complex Acetabular Bone Defect Article

Yongqiang Hao, Lei Wang, Wenbo Jiang, Wen Wu, Songtao Ai, Lu Shen, Shuang Zhao, Kerong Dai

Engineering 2020, Volume 6, Issue 11,   Pages 1285-1290 doi: 10.1016/j.eng.2020.04.013

Abstract:

Complicated and large acetabular bone defects present the main challenges and difficulty in the revisionof total hip arthroplasty (THA).Moreover, a Harris hip score was obtained to evaluate limb function.The Harris hip score indicated a very good functional recovery in all three patients.3D printing technology had a good therapeutic effect on both complex and large bone defects in the revision

Human hip joint center analysis for biomechanical design of a hip joint exoskeleton Article

Wei YANG,Can-jun YANG,Ting XU

Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 8,   Pages 792-802 doi: 10.1631/FITEE.1500286

Abstract: We propose a new method for the customized design of hip exoskeletons based on the optimization of theThe approach is based on mechanisms designed to follow the natural trajectories of the human hip as theThe motions of the hip joint center with variation of the flexion angle were measured and the resultingThe resulting design can reduce human-machine interaction forces by 24.1% and 76.0% during hip flexionduring hip joint flexion or abduction by applying the resulting design.

Frontiers of Information Technology & Electronic Engineering 2015, Volume 16, Issue 7,   Pages 579-593 doi: 10.1631/FITEE.14a0230

Abstract: This paper presents a control algorithm for push recovery, which particularly focuses on the hip strategyfound that horizontal stability can be maintained with a suitably controlled torque applied at the hipTo solve this problem, different hip strategies are discussed for two cases when (1) external disturbanceapplied on the center of mass (CoM) and (2) external torque is acting around the CoM, and a universal hipMoreover, three torque primitives for the hip, depending on the type of disturbance, are designed to

Highly Aromatic Norditerpenoid Heterodimers and Monomers from Trigonostemon fragilis

Jun-Su Zhou,Long Cheng,Yuan Gao,Zhan-Peng Ge,Bin Zhou,Jing-Ya Li,Jin-Xin Zhao,Jian-Min Yue,

Engineering doi: 10.1016/j.eng.2023.09.015

Abstract: Four new norditerpenoid heterodimers with different dimerization patterns—namely, trigofragiloids A–C (denoted as compounds 1–3) and (+)- and (−)-trigofragiloid D (compound 4)—and three new phenanthrenone norditerpenoids—namely, trigofragiloids E–G (compounds 5–7)—were isolated from Trigonostemon fragilis. Compounds 1 and 2 feature a novel heterodimeric carbon skeleton formed by the conjugation of a tetra-norditerpenoid and an ennea-norditerpenoid; they have been identified as class 2 atropisomers by means of quantum chemical calculations. Compound 3 is an unprecedented phenylpropanoid-norditerpenoid adduct with a new dimerization pattern. Compounds (+)- and (−)-4 are the first example of S-shaped 1,4-dioxane-fused norditerpenoid dimers. Inspired by the structure elucidation of compound 4, two co-occurring analogues, actephilol A and epiactephilol A, were structurally revised as a pair of geometrical isomers and were identified as two pairs of enantiomers, (+)- and (−)-8 and (+)- and (−)-9, respectively. Their structures were characterized using a combined method. Notably, compound 7 exhibits remarkable adenosine triphosphate-citrate lyase (ACLY) inhibition with a half-maximal inhibition concentration (IC50) value of (0.46 ± 0.11) μmol∙L−1, as active as the positive control BMS-303141, and a molecular docking study offers deep insight into the interaction between compound 7 and ACLY.
