Research ArticleOpen accessEvery word in the titleEvaluating the Usability of Model Transformations Testing Approach (MTTA)Lukman Ab. Rahim, Ziyaulhaq Aliyu, Emy E. MustaphaModel Transformation (MT) is a key component in Model Driven Development (MDD). Model transformation is used to transform source model into a target model, improve the model quality and also introduce the design pattern and refactoring. Model transformation are not free from bugs similar to other software development artifacts and it needs to be verified. Code Generators (CG) are a … …Journal of Computer Science, Vol. 13, Issue 1 · 6 Mar 2017 · 7,675 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleCost Elasticities of Reliability and MTTF for k-out-of-n SystemsAli Muhammad Rushdi, Abdulaziz Efain AlsulamiThe application of the concept of cost elasticity of reliability was extended from the parallel system to the partially redundant or k-out-of-n:G(F) system (or k-out-of-n system, for short). An expression for the cost elasticity of reliability was derived for a general k-out-of-n system. The expression yielded acceptable results for a wide range of values for k, n, and component reliability. … …Journal of Mathematics and Statistics, Vol. 3, Issue 3 · 30 Sep 2007 · 7,295 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsEffects of a Cyclachaena Xanthiifolia Extract on Trematodes Opisthorchis Felineus: An in Vitro StudyDenis Ponomarev, Elena Khramova, Natalia Gubanova et al.Cyclachaena xanthiifolia is a phytochemically rich invasive weed with documented allelopathic properties, making it a candidate source of bioactive compounds with potential medicinal applications. This study investigated the anthelmintic activity of a crude aqueous-ethanolic extract of C. xanthiifolia (CxEt), prepared from equal proportions of leaves and seeds, against the trematode Opisthorchis felineus in vitro. The effects of CxEt on the … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 1 Jun 2026 · 1,251 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsUse of Novel Triphenyltin (IV) Dithiocarbamate Compounds in Assessing the Cytotoxicity and Mode of Cell Death of Acute Lymphoblastic Leukemia Cell Lines, CCRF CEM (CCL-119)Normah Awang, Nur Hidayah Hasrin, Nurul Farahana Kamaludin et al.Chemotherapy and radiotherapy are often used to treat Acute Lymphoblastic Leukemia (ALL). However, the resistance problem of treatment using the current drug in ALL patients has decreased the effectiveness of such therapy. Therefore, a study needs to be conducted to identify the potential of new anticancer agents. Organotin (IV) dithiocarbamate, an organometallic compound, causes toxic effects on cancer cells in … …OnLine Journal of Biological Sciences, Vol. 23, Issue 2 · 10 Mar 2023 · 5,159 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsSynthesis, 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 PDF Cite

Research ArticleOpen accessIn the keywordsAnti-Proliferative Activity of Zerumbone Against Tumour Cell LinesAdel Sharaf Al-ZubairiZerumbone (ZER) is a cytotoxic phytochemical component extracted from the tropical herbal plant, Zingiber Zerumbet smith. It has been identified as an active anticancer compound. This study was aimed to evaluate in vitro the anti-proliferative activity of this bioactive compound, zerumbone, on seven cancer cell lines namely: CEMss (T4-lymphoplastoid), Chinese Hamster Ovary (CHO), 3T3 (mouse fibroblast), WEHI-3 (murine monomyelocytic leukemia), … …OnLine Journal of Biological Sciences, Vol. 18, Issue 2 · 25 Apr 2018 · 8,317 accessesView PDF Cite
