    Journal of Renewable Materials, Vol.11, No.1, pp. 435-451, 2023, DOI:10.32604/jrm.2022.023214

    Abstract This study aims to improve the value of fast-growing wood and extend the heat-treated wood utilization using inorganic calcium carbonate (CaCO3) crystals via an in-situ synthesis method. CaCl2 and Na2CO3 solutions with a concentration ratio of 1:1 were successively introduced into the thermally modified poplar wood obtained by steam heat treatment (HT) at 200°C for 1.5 and 3 h, resulting in the in-situ synthesis of CaCO3 crystals inside the heat-treated wood. The filling effect was best at the concentration of 1.2 mol/L. CaCO3 was uniformly distributed in the cell cavities of the heat-treated wood, and some of the… More > Graphic Abstract

    Physiological and Biochemical Mechanisms of Exogenous Calcium Chloride on Alleviating Salt Stress in Two Tartary Buckwheat (Fagopyrum tataricum) Varieties Differing in Salinity Tolerance

    Tao Zhang*, Hongbing Yang

    Phyton-International Journal of Experimental Botany, Vol.91, No.8, pp. 1643-1658, 2022, DOI:10.32604/phyton.2022.019572

    Abstract Salt stress is one of the most serious abiotic stresses limiting plant growth and development. Calcium as an essential nutrient element and important signaling molecule plays an important role in ameliorating the adverse effect of salinity on plants. This study aimed to investigate the impact of exogenous calcium on improving salt tolerance in Tartary buckwheat cultivars, cv. Xinong9920 (salt-tolerant) and cv. Xinong9909 (salt-sensitive). Four-week-old Tartary buckwheat seedlings under 100 mM NaCl stress were treated with and without exogenous calcium chloride (CaCl2), Ca2+ chelator ethylene glycol tetraacetic acid (EGTA) and Ca2+-channel blocker lanthanum chloride (LaCl3) for 10 days.… More >

    Nicotinic acid induces apoptosis of glioma cells via the calcium-dependent endoplasmic reticulum stress pathway


    BIOCELL, Vol.46, No.4, pp. 1041-1051, 2022, DOI:10.32604/biocell.2022.017383

    Abstract Malignant glioma is one of the most common and deadly tumors in the central nervous system while developing effective treatments for this devastating disease remains a challenge. Previously, we demonstrated that the vitamin nicotinic acid (NA) inhibits glioma invasion. Here, we show that high-dose NA induces apoptosis of malignant glioma cells in vitro and in vivo. In cultured U251 glioma cells treated with NA, we detected ER stress that was likely caused by elevated intracellular calcium levels. The elevated calcium can be attributed to the activation of TRPV1, a cation channel that has been implicated in cutaneous More >

    Calcium supplementation in colorectal cancer prevention: A systematic meta-analysis of adverse events


    BIOCELL, Vol.46, No.3, pp. 759-767, 2022, DOI:10.32604/biocell.2022.016586

    Abstract Despite the multiple systematic reviews and meta-analyses accumulating evidence on the preventive effect of calcium supplementation for colorectal cancer, most of the associated adverse effects are not systematically analyzed. The aim of the study is evaluating adverse events associated with calcium supplementation for colorectal cancer prevention through a systematic meta-analysis. We searched Medline, PubMed Central, EMBASE (Excerpta Medica database), Scopus, Cochrane Central Register of Controlled Trials, and Web of Science published in English from database inception up to 31 July 2019. In the current systematic meta-analysis, we included human studies (including cohort studies, clinical trials,… More >

    Production of Bio-Calcium Oxide Derived from Hatchery Eggshell Waste Using an Industrial-Scale Car Bottom Furnace

    Ajchara Imkum Putkham1, Suwanan Chuakham2, Yuwadee Chaiyachet2, Tanapon Suwansopa2, Apipong Putkham2,*

    Journal of Renewable Materials, Vol.10, No.4, pp. 1137-1151, 2022, DOI:10.32604/jrm.2022.018560

    Abstract The valorization of eggshell waste as bio-calcium oxide is crucial for pollution prevention and supporting sustainable development. There are several reports on the thermal conversion of eggshell waste to calcium oxide for the partial or complete substitution of natural lime applications. However, this paper reports the thermal decomposition of large amounts of hatchery eggshell waste on an industrial-scale car bottom furnace for the first time. The hatchery eggshell waste was sundried and placed into five stacked trays in the car bottom furnace. The calcination of the eggshell waste was conducted at 900°C for 3 and… More > Graphic Abstract

    Calcium chloride linked camel milk derived casein nanoparticles for the delivery of sorafenib in hepatocarcinoma cells


    BIOCELL, Vol.46, No.1, pp. 127-136, 2022, DOI:10.32604/biocell.2021.015932

    Abstract Sorafenib, a multikinase inhibitor used for the treatment of hepatocellular carcinoma, is limited by its low oral bioavailability. To overcome this drawback, we have developed novel camel milk casein-derived nanoparticles as a drug delivery system. Camel milk casein is not only biocompatible on oral administration but is actually a dietary protein of pharmaceutical relevance. Casein is used because of its amphiphilic nature, self-assembling property, ability to show sustained release, and capability of encapsulating both hydrophilic and hydrophobic drugs. In this study, camel milk casein nanoparticles loaded with sorafenib were developed and characterized. Characterization of casein… More >

    Identification of key pathways and gene expression in the activation of mast cells via calcium flux using bioinformatics analysis


    BIOCELL, Vol.45, No.2, pp. 395-415, 2021, DOI:10.32604/biocell.2021.012280

    Abstract Mast cells are the main effector cells in IgE-associated allergic disorders, and we have reported that mucosal mast cells (MMCs) play a more important role in the development of food allergy (FA). IgE with antigen or calcium ionophore stimulation can lead to the activation of MMCs via a calcium-dependent pathway. The purpose of the present study was to identify gene signatures with IgE/antigen (dinitrophenyl-bovine serum albumin, DNP-BSA) or calcium ionophore (A23187) on the activation of MMCs. Differentially expressed genes between the two types of samples were identified with microarray analysis. Gene ontology functional and pathway… More >

    Congenital Heart Disease, Vol.14, No.2, pp. 213-220, 2019, DOI:10.1111/chd.12696

    Abstract Background: We previously described the association of genetic variants in calcium channel genes and susceptibility to Kawasaki disease (KD), an acute, self‐limited vas‐ culitis, and the most common cause of acquired cardiac disease in children. Abnormal repolarization of cardiomyocytes and changes in T wave morphology have been re‐ ported in KD but have not been studied systematically.
    Methods: We analyzed acute and convalescent ECG T wave morphology in two inde‐ pendent cohorts of KD subjects and studied the association between bifid T waves and genetic variants in previously reported genes with SNVs associated with cardiac repolarization.
    Results: Bifid… More >
