    Investigation of Single and Multiple Mutations Prediction Using Binary Classification Approach

    T. Edwin Ponraj1,*, J. Charles2

    Intelligent Automation & Soft Computing, Vol.36, No.1, pp. 1189-1203, 2023, DOI:10.32604/iasc.2023.033383

    Abstract The mutation is a critical element in determining the proteins’ stability, becoming a core element in portraying the effects of a drug in the pharmaceutical industry. Doing wet laboratory tests to provide a better perspective on protein mutations is expensive and time-intensive since there are so many potential mutations, computational approaches that can reliably anticipate the consequences of amino acid mutations are critical. This work presents a robust methodology to analyze and identify the effects of mutation on a single protein structure. Initially, the context in a collection of words is determined using a knowledge graph for feature selection purposes.… More >

    New Renewable and Biodegradable Particleboards from Jatropha Press Cakes

    Philippe Evon1,2,*, Ika A. Kartika3, Luc Rigal1,2

    Journal of Renewable Materials, Vol.2, No.1, pp. 52-65, 2014, DOI:10.7569/JRM.2013.634131

    Abstract The infl uence of thermo-pressing conditions on the mechanical properties of particleboards obtained from Jatropha press cakes was evaluated in this study. Conditions such as molding temperature and press cake oil content were included. All particleboards were cohesive, with proteins and fibers acting respectively as binder and reinforcing fillers. Generally, it was the molding temperature that most affected particleboard mechanical properties. The most resistant boards were obtained using 200°C molding temperature. Glass transition of proteins then occurred during molding, resulting in effective wetting of the fi bers. At this optimal molding temperature, the best compromise between fl exural properties (7.2… More >

    A SEM Record of Proteins-Derived Microcellular Silicon Carbide Foams

    A. Pizzi1,2,*, C. Zollfrank3, X. Li1, M. Cangemi1, A. Celzard4

    Journal of Renewable Materials, Vol.2, No.3, pp. 230-234, 2014, DOI:10.7569/JRM.2014.634114

    Abstract Protein rigid foams based on albumin coreacted with camphor and an aldehyde were converted into silicon carbide (SiC) foams. This was carried out by putting albumin-derived template foams in contact with silicon compounds in liquid phase and calcinating the mix obtained at a relatively low temperature of 500°C to eliminate the protein and leave the SiC foam. The transformation was followed by scanning electron microscopy (SEM) from the natural albumin foams to the gel obtained by infi ltrating them with tetraethyl orthosilicate (TEOS) and to the appearance of the SiC foams after calcination. X-ray diffraction (XRD) and Raman spectra were… More >

    Munir Ozturk1,*, Mert Metin2, Volkan Altay3, Tomonori Kawano2, Alvina Gul4, Bengu Turkyilmaz Unal5,*, Dilek Unal6, Rouf Ahmad Bhat7, Moonisa Aslam Dervash8, Kristina Toderich9, Esra Koc10, Pedro Garcia Caparros11, Andleeb Shahzadi12

    Phyton-International Journal of Experimental Botany, Vol.92, No.1, pp. 165-192, 2023, DOI:10.32604/phyton.2022.022038

    Abstract Aluminum is an abundant metal in the earth’s crust that turns out to be toxic in acidic environments. Many plants are affected by the presence of aluminum at the whole plant level, at the organ level, and at the cellular level. Tobacco as a cash crop (Nicotiana tabacum L.) is a widely cultivated plant worldwide and is also a good model organism for research. Although there are many articles on Al-phytotoxicity in the literature, reviews on a single species that are economically and scientifically important are limited. In this article, we not only provide the biology associated with tobacco Al-toxicity,… More >

    Wheat Lysin-Motif-Containing Proteins Characterization and Gene Expression Patterns under Abiotic and Biotic Stress

    Minjie Liu*, Na Gao, Yaqiong Zhao, Yingpeng Wu, Zongying Yuan

    Phyton-International Journal of Experimental Botany, Vol.91, No.11, pp. 2367-2382, 2022, DOI:10.32604/phyton.2022.021406

    Abstract Lysin motif (LysM)-containing proteins (LYPs) are important pattern recognition receptors in plants. However, the evolutionary history and characteristics of LYP genes remain largely unclear in wheat. In this study, 62 LYPs were identified at genome wide in wheat. Based on phylogenetic and domain analysis, wheat LYPs were classified into 6 subgroups (group LysMe, LysMn, LYP, LYK, LysMFbox). Syntenic analysis showed the evolution of LYP genes in wheat. RNA-seq data showed that 22 genes were not expressed at any tissue or stress stimulation period. Some LYP and LYK genes were tissue- or stage- specific. The majority of TaLYK5s, TaLYK6s, TaLYP2s and… More >

    The Effect of Oncogene Proteins of Human Papillomaviruses on Apoptosis Pathways in Prostate Cancer

    Robabeh Faghani Baladehi1,2, Mohammad Yousef Memar1, Abolfazl Jafari Sales3, Ahad Bazmani1,4, Javid Sadri Nahand1,5,6, Parisa Shiri Aghbash2,7, Hossein Bannazadeh Baghi1,2,7,*

    Oncologie, Vol.24, No.2, pp. 227-245, 2022, DOI:10.32604/oncologie.2022.020648

    Abstract The ability of host cells to activate apoptosis is perhaps the most potent weapon for helping cells eliminate viruses. Human papillomaviruses (HPV) activate several pathways, enabling the infected cells to avoid extrinsic and intrinsic apoptosis pathways. The incapacity of prostatic epithelial cells to induce apoptosis leads to the invasive development of prostate cancer. For the pathogenesis of prostate cancer, several risk factors have been reported; for example, some viruses and infectious diseases have been proposed as causative agents for their relation to prostate diseases. According to several studies, high-risk human papillomaviruses cause malignancy by interfering with the apoptotic and inflammatory… More >

    Prediction of Intrinsically Disordered Proteins Based on Deep Neural Network-ResNet18

    Jie Zhang, Jiaxiang Zhao*, Pengchang Xu

    CMES-Computer Modeling in Engineering & Sciences, Vol.131, No.2, pp. 905-917, 2022, DOI:10.32604/cmes.2022.019097

    Abstract Accurately, reliably and rapidly identifying intrinsically disordered (IDPs) proteins is essential as they often play important roles in various human diseases; moreover, they are related to numerous important biological activities. However, current computational methods have yet to develop a network that is sufficiently deep to make predictions about IDPs and demonstrate an improvement in performance. During this study, we constructed a deep neural network that consisted of five identical variant models, ResNet18, combined with an MLP network, for classification. Resnet18 was applied for the first time as a deep model for predicting IDPs, which allowed the extraction of information from… More >

    Crosslinking-mediated activation of the FcεRI: Does it need antigen for success?

    MICHAEL HUBER*, SANDRO CAPELLMANN

    BIOCELL, Vol.46, No.5, pp. 1125-1129, 2022, DOI:10.32604/biocell.2022.018513

    Abstract Mast cells (MCs), hematopoietic cells of the myeloid lineage, are well-known for their pro-inflammatory nature contributing to the development of various allergic and autoimmune diseases. One of the characteristic receptors on MCs, the high-affinity receptor for IgE (FcεRI), is activated in its IgE-bound state via binding and crosslinking by polyvalent antigen. This results in its phosphorylation by the SRC family kinase LYN, initiating differential signaling pathways, eventually triggering immunological effector functions, such as degranulation and cytokine production. Few publications have reported on FcεRI-dependent but antigen-independent MC activation by antibody-mediated crosslinking of membrane molecules (e.g., transmembrane proteins and glycosphingolipids) that are… More >

    Secretome-microRNA and anti-proliferative APRO family proteins as cancer prevention and stem cell research strategies

    YUKA IKEDA, NOZOMI NAGASE, AI TSUJI, KURUMI TANIGUCHI, YASUKO KITAGISHI, SATORU MATSUDA*

    BIOCELL, Vol.46, No.5, pp. 1163-1167, 2022, DOI:10.32604/biocell.2022.018177

    Abstract Stemness of cancer cells contains limitless self-renewal proliferation. For the purpose of proliferation, secretome might exert its effects via the paracrine signaling. Specific microRNAs enclosed in the secretome of cancer stem cells could regulate the expression of anti-proliferative APRO family proteins. The biological functions of APRO family proteins seems to be quite intricate, however, which might be a key modulator of microRNAs, then could regulate the proliferation of cancer cells. In addition to affecting proliferation/differentiation during cellular development, APRO family proteins might also play an imperious role on keeping homeostasis in healthy stem cells under a physiological condition. Therefore, relationship… More >

    Mechanism of tobacco osmotin gene in plant responses to biotic and abiotic stress tolerance: A brief history

    HAKIM MANGHWAR1,#,*, AMJAD HUSSAIN2,#

    BIOCELL, Vol.46, No.3, pp. 623-632, 2022, DOI:10.32604/biocell.2022.017316

    Abstract Plants are recurrently exposed to myriads of biotic and abiotic stresses leading to several biochemical and physiological variations that cause severe impacts on plant growth and survival. To overcome these challenges, plants activate two primary defense mechanisms, such as structural response (cell wall strengthening and waxy epidermal cuticle development) and metabolic changes, including the synthesis of anti-microbial compounds and proteins, especially the pathogenesis-related (PR) proteins. PR proteins are members of a super large family of defense proteins that exhibit antimicrobial activities. Their over-expression in plants provides tolerance to many abiotic and biotic stresses. PR proteins have been classified into 17… More >
