Correction of Left Ventricular Doppler Echocardiographic Measurements for Physiological Variances Using a Novel Optimized Multivariable Allometric Model in Healthy Chinese Han Adults Article

Guihua Yao, Xiangyun Chen, Wenjing Yang, Qing Zhang, Jing Liu, Huan Liang, Hui Sun, Yao Xu, Li Wang, Jinfeng Xu, Cheng Zhang, Fengrong Sun, Mei Zhang, Xueying Zeng, Yun Zhang

Engineering 2022, Volume 16, Issue 9, Pages 115-122 doi: 10.1016/j.eng.2021.05.007

Abstract:

Most left ventricular (LV) Doppler measurements vary significantly with age and gender, making it necessary to correct them for physiological variances. We aimed to verify the hypothesis that different Doppler measurements correlate nonlinearly with different biometric variables raised to different scaling factors and exponents. In this work, a total of 23 LV Doppler parameters were measured in 1224 healthy Chinese adults. An optimized multivariable allometric model (OMAM) and scaling equations were developed in 70% of the subjects (group A), and the reliability of the model and equations was verified using the remaining 30% of the subjects (group B) as well as 183 overweight subjects (group C). The single-variable isometric model (SVIM) with body surface area (BSA) as a scaling variable was used for comparison. Before correction, all 23 LV Doppler parameters correlated significantly with one or more of the biometric variables. In group B, gender differences were found in 47.8% (11/23) of the parameters and were eliminated in 81.8% (9/11) of the parameters after correction with OMAM. The successful correction rate with OMAM was 100% (23/23) in group B and 82.6% (19/23) in group C. New reference values for corrected Doppler measurements independent of biometric variables were established. The SVIM with BSA successfully corrected none of the 23 parameters. In conclusion, different LV Doppler parameters allometrically correlated with one or more of the biometric variables. The novel OMAM developed in this study successfully corrected the effects of the physiological variances of most biometric variables on Doppler measurements in healthy and overweight subjects, and was found to be far superior to the SVIM. However, whether the OMAM equations can be applied to other ethnicities, obese subjects, and pathological conditions requires further investigation.

Systems biomedical analysis of Schistosoma japonicum

Ze-Guang HAN MD,

Frontiers of Medicine 2010, Volume 4, Issue 2, Pages 157-165 doi: 10.1007/s11684-010-0034-5

Abstract: Human schistosomiasis, caused mainly by three principal species including , , and , remains a major public health concern worldwide. is prevalent in southern China, being a major disease risk for 66 million people. The blood fluke has a complex life cycle for survival: as a free-living form in fresh water and as a parasite in the snail intermediate and vertebrate definitive hosts. Systems-based biomedical analyses, including genomic, transcriptomic, proteomic and metabonomic approaches, have been performed on the schistosome. These comprehensive investigations have not only characterized the genomic features but also chartered gene and protein expression profiles across genders and developmental stages. The integration of the huge information will lay a global and solid foundation for the molecular architecture of the biology, pathogenesis, and host-parasite interactions of the human blood fluke, which will facilitate the development of a new antischistosomal vaccine and drugs as well as diagnostic markers for the treatment and control of schistosomiasis.

Numerical analysis and experimental investigation of modal properties for the gearbox in wind turbine

Pengxing YI,Peng HUANG,Tielin SHI

Frontiers of Mechanical Engineering 2016, Volume 11, Issue 4, Pages 388-402 doi: 10.1007/s11465-016-0404-z

Abstract:

Wind turbine gearbox (WTG), which functions as an accelerator, ensures the performance and service life of wind turbine systems. This paper examines the distinctive modal properties of WTGs through finite element (FE) and experimental modal analyses. The study is performed in two parts. First, a whole system model is developed to investigate the first 10 modal frequencies and mode shapes of WTG using flexible multi-body modeling techniques. Given the complex structure and operating conditions of WTG, this study applies spring elements to the model and quantifies how the bearings and gear pair interactions affect the dynamic characteristics of WTGs. Second, the FE modal results are validated through experimental modal analyses of a 1.5 WM WTG using the frequency response function method of single point excitation and multi-point response. The natural frequencies from the FE and experimental modal analyses show favorable agreement and reveal that the characteristic frequency of the studied gearbox avoids its eigen-frequency very well.
