    New Soliton Wave Solutions to a Nonlinear Equation Arising in Plasma Physics

    M. B. Almatrafi, Abdulghani Alharbi*

    CMES-Computer Modeling in Engineering & Sciences, Vol.137, No.1, pp. 827-841, 2023, DOI:10.32604/cmes.2023.027344

    Abstract The extraction of traveling wave solutions for nonlinear evolution equations is a challenge in various mathematics, physics, and engineering disciplines. This article intends to analyze several traveling wave solutions for the modified regularized long-wave (MRLW) equation using several approaches, namely, the generalized algebraic method, the Jacobian elliptic functions technique, and the improved Q-expansion strategy. We successfully obtain analytical solutions consisting of rational, trigonometric, and hyperbolic structures. The adaptive moving mesh technique is applied to approximate the numerical solution of the proposed equation. The adaptive moving mesh method evenly distributes the points on the high error areas. This method perfectly and… More >

    Calcitriol induces post-thawed bovine sperm capacitation


    BIOCELL, Vol.47, No.5, pp. 1135-1143, 2023, DOI:10.32604/biocell.2023.027628

    Abstract Background: Capacitation is a set of physiological changes sperms undergo to acquire fertilizing capacity. In vivo, this process is directly associated with high calcium levels in sperm cytoplasm. Calcitriol, the vitamin D hypercalcemic metabolite, is related to human sperm motility, capacitation, and acrosome reaction. This work aimed to study the effect of calcitriol on bull sperm quality parameters and capacitation. Methods: One million freeze-thawed spermatozoa were obtained from different bulls and treated with 20 nM of calcitriol for 30 min. Untreated cells (negative control) and treated ones with calcitriol or heparin (100 µg/mL, positive capacitation control) were evaluated for motility,… More >

    Low-Temperature Synthesis of Nano-AlN Based on Solid Nitrogen Source by Plasma-Assisted Ball Milling

    Zhuoli Yang1, Xianbin Hou2, Leyang Dai2,*

    Journal of Renewable Materials, Vol.11, No.6, pp. 2941-2951, 2023, DOI:10.32604/jrm.2023.025723

    Abstract Plasma-assisted ball milling was carried out on the Al+C3H6N6 system and Al+C4H4N4 system, respectively. The phase structure, functional groups and synthesis mechanism were analyzed by XRD and FT-IR, and the differences in the synthesis process of nano-AlN with different solid nitrogen sources were discussed. The results show that C3H6N6 has a stable triazine ring structure, and its chemical bond is firm and difficult to break, so AlN cannot be synthesized directly by solid-solid reaction at room temperature. However, there are a large number of nitrile groups (-CN) and amino groups (-NH2) in C4H4N4 molecules. Under the combined action of plasma… More >

    Jia An#, Xiang Wang#, Yajiang Jing, Jianping Huang, Qilong Wang, Gang Zhang, Jing Gao, Liang Peng, Wenli Huang*, Yonggang Yan*

    Phyton-International Journal of Experimental Botany, Vol.92, No.5, pp. 1405-1420, 2023, DOI:10.32604/phyton.2023.026525

    Abstract Although Platycodon grandiflorum (Jacq.) A.DC. is a renowned medicine food homology plant, reports of excessive cadmium (Cd) levels are common, which affects its safety for clinical use and food consumption. To enable its Cd levels to be regulated or reduced, it is necessary to first elucidate the mechanism of Cd uptake and accumulation in the plant, in addition to its detoxification mechanisms. This present study used inductively couple plasma-mass-spectrometry to analyze the subcellular distribution and chemical forms of Cd in different tissues of P. grandiflorum. The experimental results showed that Cd was mainly accumulated in the roots [predominantly in the… More >

    Intracellular life of protozoan Toxoplasma gondii: Parasitophorous vacuole establishment and survival strategies


    BIOCELL, Vol.47, No.4, pp. 929-950, 2023, DOI:10.32604/biocell.2023.026629

    Abstract Toxoplasma gondii is a protozoan of worldwide distribution and the agent of toxoplasmosis. It is estimated that 30%–50% of the world population could be infected with this parasite. Although the infection in immunocompetent individuals is mostly asymptomatic, the disease in immunosuppressed and pregnant is a risk condition. As a member of the phylum Apicomplexa, T. gondii has an obligatory intracellular lifestyle; therefore, invading a host cell and establishing it inside a parasitophorous vacuole (PV) are mandatories for the survival of this parasite. The construction of a perfect intracellular niche for T. gondii requires the secretion of an arsenal of proteins… More >

    Study on the Value of Ultrasound Elastography Combined with Plasma miRNA Expression in the Early Detection of Breast Cancer

    Qian Zhang1,2,#, Yuanyuan Cao2,#, Mingming Fang3, Qin Yang2, Pingyang Zhang1,*

    Oncologie, Vol.24, No.4, pp. 717-727, 2022, DOI:10.32604/oncologie.2022.026998

    Abstract Background: Breast cancer (BC) is the most common malignant tumor in women, and its morbidity and mortality are increasing each year, due to the lack of specific clinical symptoms in the early stage of BC, and the lack of diagnostic methods for early breast cancer. Therefore, identifying an effective diagnostic method for early BC has become urgent. Materials and Methods: Breast lesions with a histological diagnosis that were examined by ultrasonic elastography (UE) in our department from June 2020 to December 2021 were reviewed. qRT-PCR was performed to measure the expression levels of miR-144-5p and miR-26b-5p in the plasma of… More >

    Surface, Thermal and Antimicrobial Release Properties of Plasma-Treated Zein Films

    S.K. Pankaj1, C. Bueno-Ferrer1, N.N. Misra1, L. O’Neill2, A. Jiménez3, P. Bourke1, P.J. Cullen1,4,*

    Journal of Renewable Materials, Vol.2, No.1, pp. 77-84, 2014, DOI:10.7569/JRM.2013.634129

    Abstract The effects of dielectric barrier discharge plasma treatment on zein fi lm containing thymol as an active ingredient were evaluated. The plasma discharge was optically characterized to identify the reactive species. A signifi cant increase in the fi lm roughness (p < 0.05) was observed due to the etching effect of DBD plasma, which was correlated with the increase in the diffusion rate of thymol in the food simulant. The diffusion of thymol from the zein fi lm was measured in aqueous solution. The kinetics of thymol release followed the Fick’s law of diffusion as shown by the high correlation… More >

    Tuning the Spatially Controlled Growth, Structural Self-Organizing and Cluster-Assembling of the Carbyne-Enriched Nano-Matrix during Ion-Assisted Pulse-Plasma Deposition

    Alexander Lukin1,*, Oğuz Gülseren2

    FDMP-Fluid Dynamics & Materials Processing, Vol.18, No.6, pp. 1763-1779, 2022, DOI:10.32604/fdmp.2022.022016

    Abstract Carbyne-enriched nanomaterials are of current interest in nanotechnology-related applications. The properties of these nanomaterials greatly depend on their production process. In particular, structural self-organization and auto-synchronization of nanostructures are typical phenomena observed during the growth and heteroatom-doping of carbyne-enriched nanostructured metamaterials by the ion-assisted pulse-plasma deposition method. Accordingly, fine tuning of these processes may be seen as the key step to the predictive designing of carbyne-enriched nano-matrices with improved properties. In particular, we propose an innovative concept, connected with application of the vibrational-acoustic effects and based on universal Cymatics mechanisms. These effects are used to induce vibration-assisted self-organized wave patterns… More >

    Platelet rich plasma–complexed hydrogel glue enhances skin wound healing in a diabetic rat model


    BIOCELL, Vol.46, No.5, pp. 1329-1338, 2022, DOI:10.32604/biocell.2022.015592

    Abstract Diabetic patients often exhibit delayed or incomplete progress in the healing of acute wounds, owing to poor blood perfusion. Platelet-rich plasma (PRP) has attracted much attention as a means to improve wound healing, because it contains high growth factor concentrations. However, the burst-like release of PRP growth factors results in a short half-life of these therapeutic proteins, thus greatly limiting the therapeutic effect. In this study, we prepared PRP from human umbilical cord blood and developed an in situ photocrosslinkable PRP hydrogel glue (HNPRP) by adding a photoresponsive hyaluronic acid (HA-NB) into PRP. The HNPRP hydrogel allowed for controlled release… More >
