    Zongshuai Liu1, Xuyu Xiang1,2,*, Jiaohua Qin1, Yun Tan1, Qin Zhang1, Neal N. Xiong3

    CMC-Computers, Materials & Continua, Vol.66, No.1, pp. 457-466, 2021, DOI:10.32604/cmc.2020.012165

    Abstract In recent years, with the development of machine learning and deep learning, it is possible to identify and even control crop diseases by using electronic devices instead of manual observation. In this paper, an image recognition method of citrus diseases based on deep learning is proposed. We built a citrus image dataset including six common citrus diseases. The deep learning network is used to train and learn these images, which can effectively identify and classify crop diseases. In the experiment, we use MobileNetV2 model as the primary network and compare it with other network models in the aspect of speed,… More >

    BIOCELL, Vol.44, No.3, pp. 337-344, 2020, DOI:10.32604/biocell.2020.011470

    Abstract This study was carried out to compare individuals diagnosed with atherosclerosis and periodontal periodontitis based on the degree of change in the human beta-defensins (HBD) HBD-2, HBD-3, and calprotectin. Atherosclerosis is the most frequently observed cardiovascular disease. Dental and periodontal infections are known to provide a considerable basis for atheroma plaque formation. The study group consists of a total number of 40 subjects, with 20 patients diagnosed with atherosclerosis and chronic periodontitis and 20 systemically healthy patients diagnosed with chronic periodontitis. Clinical periodontal and blood parameters and HBD-2, HBD-3, and calprotectin biomarkers in the gingival crevicular fluid were measured. In… More >

    Identification of Crop Diseases Based on Improved Genetic Algorithm and Extreme Learning Machine

    Linguo Li1, 2, Lijuan Sun1, Jian Guo1, Shujing Li2, *, Ping Jiang3

    CMC-Computers, Materials & Continua, Vol.65, No.1, pp. 761-775, 2020, DOI:10.32604/cmc.2020.010158

    Abstract As an indispensable task in crop protection, the detection of crop diseases directly impacts the income of farmers. To address the problems of low crop-disease identification precision and detection abilities, a new method of detection is proposed based on improved genetic algorithm and extreme learning machine. Taking five different typical diseases with common crops as the objects, this method first preprocesses the images of crops and selects the optimal features for fusion. Then, it builds a model of crop disease identification for extreme learning machine, introduces the hill-climbing algorithm to improve the traditional genetic algorithm, optimizes the initial weights and… More >

    Pheochromocytoma and paraganglioma in Fontan patients: Common more than expected

    Mi Kyoung Song1, Gi Beom Kim1, Eun Jung Bae1, Young Ah Lee1, Hyun-Young Kim2, Seung-Kee Min3, Jung Hee Kim4, Jae-Kyung Won5

    Congenital Heart Disease, Vol.13, No.4, pp. 608-616, 2018, DOI:10.1111/chd.12625

    Abstract Objective: Pheochromocytoma and paraganglioma (extra-adrenal pheochromocytoma) are rare neuroendocrine tumors that arise from the neuroendocrine cells. Chronic hypoxia is known as a possible cause, and a strong link between cyanotic congenital heart disease and these tumors has been reported. However, reports of phechromocytoma/paraganglioma in Fontan patients were scarce. We herein report seven cases of phechromocytoma/paraganglioma after Fontan operation at a single tertiary center.
    Methods: We retrospectively reviewed medical records and imaging studies who diagnosed as phechromocytoma/paraganglioma after Fontan operation in Seoul National University Children’s Hospital.
    Results: Seven patients were identified during follow-up after Fontan operation, and the prevalence was 2.5%… More >

    Abstract The virus SARS-CoV2, which causes coronavirus disease (COVID-19) has become a pandemic and has spread to every inhabited continent. Given the increasing caseload, there is an urgent need to augment clinical skills in order to identify from among the many mild cases the few that will progress to critical illness. We present a first step towards building an artificial intelligence (AI) framework, with predictive analytics (PA) capabilities applied to real patient data, to provide rapid clinical decision-making support. COVID-19 has presented a pressing need as a) clinicians are still developing clinical acumen to this novel disease and b) resource limitations… More >

    González-Álvarez M, S Moreno-Limón*, SM Salcedo-Martínez, EC Pérez-Rodríguez

    Phyton-International Journal of Experimental Botany, Vol.84, No.2, pp. 427-434, 2015, DOI:10.32604/phyton.2015.84.427

    Abstract The agricultural sector, and particularly the horticultural production, has a singular importance in agriculture, considering that it ranks second on agricultural products, nationally and worldwide. Fungal diseases are one of the major causes of vegetable loss during storage, reducing their nutritional value, quality and sale price. Vegetables are usually exposed to diverse treatments with chemical products before storage; as a result, fungal populations develop an increased resistance over time becoming more difficult to control. Because of this, research efforts toward finding more suitable chemicals to control fungal diseases are needed. Natural extracts may be an alternative solve this problem. In… More >

    Smudge and other diseases of onion caused by Colletotrichum circinans, in southern Argentina

    Kiehr M1, R Delhey1, A Azpilicueta2

    Phyton-International Journal of Experimental Botany, Vol.81, pp. 161-164, 2012, DOI:10.32604/phyton.2012.81.161

    Abstract While studying the etiology of onion diseases in southern Argentina, a coelomycetous fungus was found associated with diverse disease expressions. They included the typical smudge symptoms in white onion bulbs in local markets as well as field infections on yellow- and red-coloured cultivars, with severe infections on transplants in the seed-bed. The fungus was isolated and identified as Colletotrichum circinans on the basis of its morphological, morphometric, biological and pathological characteristics. Two isolates, obtained from white bulbs and from transplants, were inoculated on bulbs of white and yellow-coloured cultivars and produced the typical smudge symptoms on the outer scales.
