| 1 | Free vibration analysis of a pre-twisted sandwich blade with thermal barrier coatings layers显示文摘A rotating cantilever sandwich-plate model with a pre-twisted and pre-set angle has been developed to investigate the vibrational behavior of an aero-engine turbine blade with thermal barrier coating(TBC) layers. The classic von Karman plate theory and the first-order shear deformation theory are applied to derive the energy equations of the rotating TBC blade, in which the geometric shapes, the work ambient temperature, and the TBC material properties are considered. The Chebyshev-Ritz method is used to obtain the nature frequency of the rotating TBC blade. For static frequency and modal analysis, the finite-element method(FEM)is also applied to compare and validate the results from the Chebyshev-Ritz method. A good agreement is found among these kinds of methods. For dynamic frequency, the results are analyzed in detail concerning the influence of system parameters such as the thickness of the TBC layer, the working temperature, and the pre-twisted and pre-set angle. Finally, the Campbell diagram is demonstrated to analyze the resonance property of the cantilever sandwich TBC blade model. | CAO DongXing LIU BingYi YAO MingHui ZHANG Wei | 2017 | Science China(Technological Sciences)2017，60，11： | 7 |
| 2 | The role of CYP1A1/2 in cholesterol ester accumulation provides a new perspective for the treatment of hypercholesterolemia显示文摘Cholesterol is an important precursor of many endogenous molecules.Disruption of cholesterol homeostasis can cause many pathological changes,leading to liver and cardiovascular diseases.CYP1A is widely involved in cholesterol metabolic network,but its exact function has not been fully elucidated.Here,we aim to explore how CYP1A regulates cholesterol homeostasis.Our data showed that CYP1A1/2 knockout(KO)rats presented cholesterol deposition in blood and liver.The serum levels of low-density lipoprotein cholesterol,high-density lipoprotein cholesterol and total cholesterol were significantly increased in KO rats.Further studies found that the lipogenesis pathway(LXRa-SREBP1-SCD1)of KO rats was activated,and the key protein of cholesterol ester hydrolysis(CES1)was inhibited.Importantly,lansoprazole can significantly alleviate rat hepatic lipid deposition in hypercholesterolemia models by inducing CYP1A.Our findings reveal the role of CYP1A as a potential regulator of cholesterol homeostasis and provide a new perspective for the treatment of hypercholesterolemia. | Jian Lu Xuyang Shang Bingyi Yao Dongyi Sun Jie Liu Yuanjin Zhang He Wang Jingru Shi Huaqing Chen Tieliu Shi Mingyao Liu Xin Wang | 2023 | Acta Pharmaceutica Sinica B2023，13，2： | 0 |
