Research ArticleOpen accessEvery word in the titleMomordica balsamina Fruit Extracts Enhances Selected Aspects of the Insulin Synthesis/Secretion PathwayAnanias Hodi Kgopa, Leshweni Jerry Shai, Motetelo Alfred MogalePrevious studies have suggested that crude plant extracts of the anti-diabetic medicinal plant, Momordica balsamina (MB) may exert their anti-diabetic effect through either enhancement of insulin sensitivity or inhibition of intestinal glucose absorption. However, the effects of these MB extracts on insulin synthesis and secretion are not well documented in the literature. Therefore, a main purpose of the current research … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 17 Dec 2020 · 6,999 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSynthesis and Characterization of Cobalt, Iron and Ruthenium Catalysts for the Production of Synthetic DieselDayna M. Ortiz Rodríguez, María del C. Cotto-Maldonado, José Duconge Hernández et al.Fossil fuels are currently the world's leading source of energy. Environmental legislations, the high price of fossil fuels, the concern about the supply of these fuels and technological development, makes it necessary to search for alternative sources of energy. The production of clean liquid fuels, such as synthetic diesel from synthesis gas, by Fischer-Tropsch (FT) method, is considered a very … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 2 · 29 Apr 2020 · 7,248 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSynthesis and Characterizations of MmtO-Copolymer (St-THF) NanocompositeHattab Youcef, Hakiki WahibaNanocomposites are synthesized by one or two polymers and optimized organophilic clay proportions. The aim of Synthesis of the Organophilic clay (montmorillonite) with a two monomers to get a copolytetrahydrofuran- styrene nanocomposite by insitu polymerization. Organophilic montmorillonite (MmtO) was synthesized by ion exchange between Na+ ions in the clay and HDTMAB alkylammonium cations in an aqueous medium. The MmtO were … …American Journal of Applied Sciences, Vol. 16, Issue 10 · 19 Dec 2019 · 7,116 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSynthesis, Ant Proliferative Activity and Docking Study of New Quercetin Derivatives against MDA-MB231 Breast Cancer Cell LinesReham Adnan Al-Anssari, Rita S. Elias, Shaker A.N. AljadaanMDA-MB231 is a very aggressive and invasive triple negative breast cancer, which present with limited treatment options. Unlike other breast cancer types, it is characterized by absence of hormonal receptors of estrogen, progesterone as well as human epidermal growth factor receptor 2, rendering it unsuitable for hormonal therapy and a perfect candidate for chemotherapy. Quercetin is a common natural flavonoid … …American Journal of Applied Sciences, Vol. 16, Issue 5 · 26 Jun 2019 · 8,790 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMining, Isolation and Identification of Siderophore Synthesis Gene from Brevibacillus brevis GZDF3Miaomiao Sheng, Huake Jia, Xiaomai Tao et al.Objective of this paper is to excavate the siderophore synthesis gene from Brevibacillus brevis GZDF3 and verify its type and antibacterial effects. The method is using genome mining technology to analyze the siderophore synthesis genes and the phylogenetic tree of each synthesis gene was constructed separately. Iron free medium was utilized to induce the synthesis of siderophore and CAS liquid … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 3 · 28 Aug 2018 · 10,606 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMotivations for Remittances and Philanthropy – Lessons from a Qualitative Meta-Synthesis of LiteratureSabith Khan, Daisha M. MerrittWhy do people send remittances? Also, what are the motivations for diaspora philanthropy? While each of these questions have been addressed by scholars in different way – with the most influential theories suggesting that ‘identification’ is the key theme that explains each of these phenomenon, we contend that there is much more than purely ‘identification’ with the recipients that is … …Journal of Social Sciences, Vol. 14, Issue 1 · 3 Mar 2018 · 8,368 accessesView PDFCite
