    Study of Oil-Bearing Drill Cuttings Cleaning and De-Oiling Treatment Method for Shale Gas Reservoirs

    Jialuo Rong1,2, Shuixiang Xie3,4, Huijing Geng5, Hao Hu1,2, Shanfa Tang1,2,*, Yuanpeng Cheng1,2,*

    Energy Engineering, Vol.120, No.8, pp. 1899-1917, 2023, DOI:10.32604/ee.2023.027650

    Abstract Due to its extensive use in shale gas exploration and development, oil-based drilling fluids generate large amounts of oil-bearing drill cuttings during the drilling process. The large amount of oil-bearing drill cuttings generated during the drilling process can lead to serious secondary contamination. In this study, a wetting agent FSC-6 with good hydrophobic and oleophobic properties was synthesized to construct an efficient oil removal system. For the first time, the mechanism of this system was analyzed by using the theory of adhesion function, interfacial tension and wettability. At the same time, a combined acoustic-chemical treatment process was applied to the… More >

    Abstract In the face of cancer and at the end of life, emotional distress is common and is increasingly recognized, resulting in a significant number of requests for consultation with our specialized psychological services. The authors present a reflection on the various factors that guide their interventions with oncology and palliative care patients in a hospital setting. The challenge is to offer the right care at the right time to all patients and their loved ones who need it. The treatment plan will be adjusted according to the severity and the nature of the distress, the need to intervene within a… More >

    Genome-Wide Analysis of the KANADI Gene Family and Its Expression Patterns under Different Nitrogen Concentrations Treatments in Populus trichocarpa

    Minghui Niu1,#, Heng Zhang1,#, Xiangyang Li1, Zhibao Hu1, Hongjiao Zhang2,3, Zhiru Xu2,3, Chunpu Qu1,4,*, Guanjun Liu1,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.7, pp. 2001-2015, 2023, DOI:10.32604/phyton.2023.029350

    Abstract KANADI (KAN) is a plant-specific gene that controlled the polarity development of lateral organs. It mainly acted on the abaxial characteristics of plants to make the lateral organs asymmetrical. However, it had been less identified in woody plants. In this study, the members of the KAN gene family in Populus trichocarpa were identified and analyzed using the bioinformatics method. The results showed that a total of 8 KAN family members were screened out, and each member contained the unique GARP domain and conserved region of the family proteins. Phylogenetic analysis and their gene structures revealed that all KAN genes from… More >

    Impact of Precariousness and Perceived Social Support, on the Return to Work of Women with Breast Cancer, in the Year Following the Beginning of Adjuvant Treatments

    Influence de la précarité sociale et du soutien social perçu, sur le retour au travail des femmes ayant un cancer du sein, dans l’année suivant le début des traitements adjuvants

    B. Porro, A. Michel, F. Cousson-Gélie

    Psycho-Oncologie, Vol.16, No.2, pp. 273-281, 2022, DOI:10.3166/pson-2022-0181

    Abstract The aim is to assess the associations between social precariousness, perceived social support, and the return to work (RTW) in the first year following the beginning of adjuvant breast cancer treatment. Sixty-eight breast cancer patients encountered when starting their adjuvant treatment (T0) were followed up at 3 (T1) and 12 months (T2). Friends’ informative support at T0 favours the RTW at T1. Precariousness and negative support at T0 and T2 decrease the likelihood of RTW at T2. RTW support should be offered and tailored at the outset of treatment.

    Abstract As a common tumor of the urinary system, the morbidity and mortality related to renal carcinoma, are increasing annually. Clear cell renal cell carcinoma (CCRCC) is the most common subtype of renal cell carcinoma, accounting for approximately 75% of the total number of patients with renal cell carcinoma. Currently, the clinical treatment of ccRCC involves targeted therapy, immunotherapy, and a combination of the two. In immunotherapy, PD-1/PD-L1 blocking of activated T cells to kill cancer cells is the most common treatment. However, as treatment progresses, some patients gradually develop resistance to immunotherapy. Meanwhile, other patients experience great side effects after… More > Graphic Abstract

    BIOCELL, Vol.47, No.6, pp. 1293-1306, 2023, DOI:10.32604/biocell.2023.028199

    Abstract Background: Temporomandibular joint osteoarthritis (TMJOA) is an end-stage disease that seriously affects the patients’ quality of life. Molecular insights in advancing our understanding of TMJOA are the need of the hour. Methods: We performed RNA high-throughput sequencing and bioinformatics analysis of differentially expressed (DE) long non-coding RNA (lncRNAs), microRNAs (miRNAs), and messenger RNA (mRNAs) in human synovial TMJOA tissues. Firstly, synovium samples of TMJOA patients and non-TMJOA controls were collected for highthroughput sequencing of lncRNAs, miRNAs, and mRNAs. We then performed biological function analysis of the top 100 mRNAs with more than 2-fold differential expression, and their upstream regulated miRNAs… More >

    Abstract Background: Magnolol, a bioactive extract of the Chinese herb Magnolia officinalis has a protective effect against periodontitis. This study is aimed to explore the mechanisms involved in the functioning of magnolol against periodontitis and provide a basis for further research. Methods: Network pharmacology analysis was performed based on the identification of related targets from public databases. The Protein-protein interaction (PPI) network was constructed to visualize the significance between the targets of magnolol and periodontitis. Subsequently, Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis were performed to predict the functions and the signal regulatory pathways involved in… More >
