    Abstract Ganoderma is a genus of medicinally and economically important mushrooms in the family Ganodermataceae. Ganoderma species are popular medicinal mushrooms and their health benefits are well-documented. Ganoderma is a cosmopolitan genus that is widely distributed in both tropical and temperate regions. This genus is characterized by its unique laccate or non-laccate species with double-walled basidiospores. Here, we report on eight collections of G. gibbosum collected during surveys in Kunming, Yunnan Province, China. The specimens are described and illustrated based on macro- and micro-morphological characteristics. Total DNA of the eight G. gibbosum strains were extracted using the Biospin Fungal Extraction Kit… More >

    Phyton-International Journal of Experimental Botany, Vol.89, No.3, pp. 529-539, 2020, DOI:10.32604/phyton.2020.09143

    Abstract The main objective of the research is to assess the role of foliar application of silicon (Si) for enhancing the survival ability of wheat under drought stress through improving its morphology, physicochemical and antioxidants activities. Treatments were five doses of Si at the rate of 2, 4, 6 and 8 mM and a control. After completion of seeds germination, pots were divided into four distinct groups at various field capacity (FC) levels, such as 100% FC (well-irrigated condition), 75% FC (slight water deficit), 50% FC (modest water deficit) and 25% FC (severe water deficit stress condition). Foliar application of Si… More >

    Incidence, morphology, and progression of bicuspid aortic valve in pediatric and young adult subjects with coexisting congenital heart defects

    Talha Niaz1, Joseph T. Poterucha1, Jonathan N. Johnson1,2, Cecilia Craviari1, Thomas Nienaber1, Jared Palfreeman1, Frank Cetta1,2, Donald J. Hagler1,2

    Congenital Heart Disease, Vol.12, No.3, pp. 261-269, 2017, DOI:10.1111/chd.12429

    Abstract Background: Bicuspid aortic valve (BAV) occurs both as an isolated cardiac lesion and in association with congenital heart defects (CHD). Their aim was to identify the incidence and morphology of BAV in patients with coexisting CHD and compare their disease progression to patients with isolated BAV.
    Methods: The Mayo Clinic echocardiography database was retrospectively analyzed to identify pediatric and young adult patients (≤22 years) who were diagnosed with BAV from 1990 to 2015. The morphology of BAV was determined from the echocardiographic studies before any intervention.
    Results: Overall, 1010 patients with BAV were identified, 619 (61%) with isolated BAV and… More >

    Cardiac morphology for the millennial cardiology fellow: Nomenclature and advances in morphologic imaging

    Shankar Baskar, Seth B. Gray, Erica L. Del Grippo, Onyekachukwu Osakwe, Adam W. Powell, Justin T. Tretter

    Congenital Heart Disease, Vol.13, No.5, pp. 808-810, 2018, DOI:10.1111/chd.12675

    Abstract Cardiology fellows‐in‐training, both in adult and pediatric hospitals, need structured education in regards to congenital heart disease (CHD) nomenclature. With improved survival of patients with CHD, it is not uncommon for these patients to seek care in multiple adult and pediatric hospitals. A deep understanding of CHD nomenclature would aid in providing accurate medical and surgical care for these patients. In this forum, we share our experience with such structured education and also comment on recent advances in morphologic imaging that would aid in understanding the nomenclature. More >

    Leaflet morphology classification of the Melody Transcatheter Pulmonary Valve

    Brian A. Boe, Sharon L. Cheatham, Aimee K. Armstrong, Darren P. Berman, Joanne L. Chisolm, John P. Cheatham

    Congenital Heart Disease, Vol.14, No.2, pp. 297-304, 2019, DOI:10.1111/chd.12728

    Abstract Objective: We sought to describe the leaflet morphology variation in the Melody Transcatheter Pulmonary Valve (TPV) and evaluate associated outcomes. The Melody TPV is constructed from harvested bovine jugular venous valves which have been rigorously tested. Natural anatomic leaflet variations are seen in the Melody TPV but have not been evaluated.
    Design: A Melody TPV leaflet morphology classification system was devised after reviewing a subset of photographed and implanted TPVs. All images were blindly re‐ viewed by implanters and classified. Midterm hemodynamic outcomes and complica‐ tions of the Melody TPVs were compared by leaflet morphology.
    Results: Photographed Melody TPVs implanted… More >

    Numerical Study on Rock Breaking Mechanism of Supercritical CO2 Jet Based on Smoothed Particle Hydrodynamics

    Xiaofeng Yang1, *, Yanhong Li1, Aiguo Nie1, Sheng Zhi2, Liyuan Liu3

    CMES-Computer Modeling in Engineering & Sciences, Vol.122, No.3, pp. 1141-1157, 2020, DOI:10.32604/cmes.2020.08538

    Abstract Supercritical carbon dioxide (Sc-CO2) jet rock breaking is a nonlinear impact dynamics problem involving many factors. Considering the complexity of the physical properties of the Sc-CO2 jet and the mesh distortion problem in dealing with large deformation problems using the finite element method, the smoothed particle hydrodynamics (SPH) method is used to simulate and analyze the rock breaking process by Sc-CO2 jet based on the derivation of the jet velocity-density evolution mathematical model. The results indicate that there exisits an optimal rock breaking temperature by Sc-CO2. The volume and length of the rock fracture increase with the rising of the… More >

    Automatic Detection of Aortic Dissection Based on Morphology and Deep Learning

    Yun Tan1, #, Ling Tan2, #, Xuyu Xiang1, *, Hao Tang2, *, Jiaohua Qin1, Wenyan Pan1

    CMC-Computers, Materials & Continua, Vol.62, No.3, pp. 1201-1215, 2020, DOI:10.32604/cmc.2020.07127

    Abstract Aortic dissection (AD) is a kind of acute and rapidly progressing cardiovascular disease. In this work, we build a CTA image library with 88 CT cases, 43 cases of aortic dissection and 45 cases of health. An aortic dissection detection method based on CTA images is proposed. ROI is extracted based on binarization and morphology opening operation. The deep learning networks (InceptionV3, ResNet50, and DenseNet) are applied after the preprocessing of the datasets. Recall, F1-score, Matthews correlation coefficient (MCC) and other performance indexes are investigated. It is shown that the deep learning methods have much better performance than the traditional… More >

    BIOCELL, Vol.36, No.3, pp. 97-104, 2012, DOI:10.32604/biocell.2012.36.097

    Abstract Devices for the rotational culture of cells and the study of biological reactions have been widely applied in tissue engineering. However, there are few reports exploring the effects of rotational culture on cell morphology, nitric oxide (NO) production, and cell cycle of the endothelial cells from human umbilical vein on the stent surface. This study focuses on these parameters after the cells are seeded on the stents. Results showed that covering of stents by endothelial cells was improved by rotational culture. NO production decreased within 24 h in both rotational and static culture groups. In addition, rotational culture significantly increased… More >
