    Yang Li1,#, Runxin Fang2,#, Renyun Wang1, Qiming Dai1, Zhiyong Li2,*, Genshan Ma1
    Molecular & Cellular Biomechanics, Vol.18, No.3, pp. 119-122, 2021, DOI:10.32604/mcb.2021.017503
    Abstract Longitudinal stent foreshortening is a known phenomenon, however, the impact of coronary artery curvature on longitudinal stent foreshortening remains unclear. The aim of this study is to determine the impact of coronary artery curvature on the longitudinal stent foreshortening in the real-world scenarios. A total of 86 consecutive patients underwent coronary stent implantation were included in the present study. The degree of coronary artery curvature was defined as the length of the coronary artery curvature divided by the straight length. Longitudinal stent foreshortening was defined as the stent length after implantation divided by the stent length before implantation. The mean… More >

    Surface Topography Assessments of Spine Shape Change within the Day in Healthy Male Adults

    Jianming Lu1,*, Liangliang Xiang2, Huw Wiltshire3
    Molecular & Cellular Biomechanics, Vol.18, No.3, pp. 123-129, 2021, DOI:10.32604/mcb.2021.015993
    Abstract Surface topography is a no-invasive, radiation-free method that can measure sufficient surface spine parameters by the structured back surface scan and a precise anatomical landmarks recognition. The purpose of the present study was to measure the spine shape parameter changes within the day via the DIERS Formetric 4D analysis system. Ten male healthy volunteers were recruited to participate in the experiment. All participants were sedentary people with the average sitting time during study or work t ≥ 8 h and without any back disease in the past six months. Data were analyzed by one-way ANOVA, which set time points within… More >

    Salome Kiparoidze1,*, Nino Karumidze2, Ekaterine Bakuradze1, Irina Modebadze1, Levan Rusishvili1, Dimitri Kordzaia2, Diana Dzidziguri1
    Molecular & Cellular Biomechanics, Vol.18, No.3, pp. 131-138, 2021, DOI:10.32604/mcb.2021.015596
    Abstract According to the literature, different mechanisms and kinetics proceeding of regenerative growth has been established using the basic models of liver regeneration (after resection or chemically induced). Hence, in order to determine general regularities of the adaptive-compensatory processes in various pathological conditions, the processes taking place in the cholestatic liver of adult white rats during the first four days after common bile duct ligation have been studied. It has been shown that in cholestatic liver, compensatory-adaptive processes take place with different kinetics compared to those after resection. In particular, in response to the increased functional load caused by destructive processes… More >

    Comparison of Detection and Classification of Hard Exudates Using Artificial Neural System vs. SVM Radial Basis Function in Diabetic Retinopathy

    V. Sudha1,*, T. R. Ganesh Babu2, N. Vikram1, R. Raja2
    Molecular & Cellular Biomechanics, Vol.18, No.3, pp. 139-145, 2021, DOI:10.32604/mcb.2021.016056
    Abstract Diabetic Retinopathy (DR) is a disease that occurs in the eye which results in blindness as it passes to proliferative stage. Diabetes can significantly result in symptoms like blurring of vision, kidney failure, nervous damage. Hence it has become necessary to identify retinal damage that occurs in diabetic eye due to raised glucose level in its initial stage itself. Hence automated detection of anamoly has become very essential. The appearance of crimson and yellow lesions is considered as the earliest symptoms of DR which are called as hemorrhages and exudates. If DR is analysed at initial stage, blindness does not… More >

    Analysis of the Movement Track of Top Spinning Ball and Biomechanics in the Process of Hitting Tennis Ball

    Xia Xie*
    Molecular & Cellular Biomechanics, Vol.18, No.3, pp. 147-156, 2021, DOI:10.32604/mcb.2021.016246
    Abstract The aim of this study is to analyze the movement track of top spinning tennis ball and the biomechanics characteristics of tennis players. This study took ten tennis players as an example. The hitting process of the top spinning ball was captured by two PULNIX high-speed cameras. The images were processed by APAS motion analysis system. The results showed that the top spinning ball moved forward while rotating in the hitting process and showed a large attack force after rebounding from the land. In biomechanics, A and B had larger angles of upper limb joints and larger joint speed. The… More >
