Research ArticleOpen accessIn the author namesCytotoxicity and Apoptosis Prevailed by Tricyclohexyltin(IV) Dithiocarbamate Compounds Against Human Lung Carcinoma Cell Line (A549)Normah Awang, Nurul Amalina Abd Aziz, Nur Fatini Nordin, Nurul Farahana KamaludinIn Malaysia, lung cancer is a highly common kind of cancer and the leading cause of cancer-related deaths. This study examined the cytotoxicity of two new tricyclohexyltin(IV) dithiocarbamate compounds compounds, which are tricyclohexyltin(IV) N-methyl-N-benzyldithiocarbamate (C1) and tricyclohexyltin(IV) N-ethyl-N-benzyldithiocarbamate (C2), on lung carcinoma cell lines (A549) of humans. The cytotoxicity was assessed using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) assay. Cell death mode … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 13 Jun 2024 · 4,622 accessesView PDFCite
Research ArticleOpen accessIn the author namesUse 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 PDFCite
Research ArticleOpen accessIn the author namesCharacterizing Soil Penetration Resistance of Planted Sago Palm (Metroxylon spp.) Under Mineral Soils EcosystemMohd Effendi Wasli, Nurul Hidayah Che Ali, Roland Yong et al.In-situ soil assessment such as field soil compaction can often be a helpful approach in help determining soil suitability for certain crops. In this study, an assessment was conducted to characterize the Soil Penetration Resistance (SPR) in planted sago palm (Metroxylon spp.) plantation at different growth of rosette and trunking stages under mineral soils ecosystem. SPR in-situ assessment would provide … …OnLine Journal of Biological Sciences, Vol. 21, Issue 4 · 20 Dec 2021 · 6,731 accessesView PDFCite
Review ArticleOpen accessIn the author namesComparative Study of Visual Odometry Performance Based on Road ClassificationsDayang Nur Salmi Dharmiza, Awang Salleh, Kuryati KipliAccuracyand robustness are among the main concerns in vehicle positioning systems andautonomous applications. These concerns are crucial in GNSS-deniedenvironments; thus, we need an alternative technology to overcome this problem.In recent years, vision-based localization known as visual odometry has gainedconsiderable attention among researchers. Visual odometry is a vision-basedpose estimation and it has been developed for mobile object localization suchas robots and … …Journal of Computer Science, Vol. 18, Issue 11 · 26 Oct 2022 · 5,899 accessesView PDFCite
Research ArticleOpen accessIn the author namesCytotoxic Activity of Tinospora crispa Crude Extracts (Stem) Against K562 Human Leukemia CellsNormah Awang, Haziratul Iffah Ruzali, Rapidah Mohamad et al.Tinospora crispa (T. crispa) is traditionally used as an herbal medicine for treatment of gout and is an analgesic, anti-inflammatory and antihyperuricemic agent. Cytotoxicity of hexane, dichloromethane, ethanol and aqueous extracts of T. crispa stem against K562 cells was assessed. Crude extracts of T. crispa stem were obtained by sonication and maceration methods. T. crispa stem powder was macerated and … …OnLine Journal of Biological Sciences, Vol. 19, Issue 2 · 11 May 2019 · 7,870 accessesView PDFCite
Research ArticleOpen accessIn the author namesSEVQER: Automatic Semantic Visual Query Builder to Support Intelligent Image Search in Traffic ImagesHui-Hui Wang, Phei-Chin Lim, Yin-Chai Wang et al.Image search is a challenging process in the field of Content Based Image Retrieval (CBIR). Image search-by-example, search-by-keyword and search-by-sketch methods seldom provide user interface that allows user to accurately formulate their search intent easily. To overcome such issue, a novel image search interface-Semantic Visual Query Builder (SeVQer) is proposed as a non-verbal interface which allows user to drag and … …Journal of Computer Science, Vol. 14, Issue 7 · 6 Aug 2018 · 7,680 accessesView PDFCite
Research ArticleOpen accessIn the author namesScheduling Jobs through Gap Filling and Optimization Techniques in Computational GridOmar Dakkak, Shahrudin Awang Nor, Suki ArifDue to the heterogeneity and complexity in grid computing, classical algorithms may not be able to deal with dynamic jobs properly. In the dynamic mode, incoming jobs reach the scheduler arbitrary. Therefore, scheduling the jobs using simple policy alone deteriorates the performance of the scheduler. Thus, a policy that can handle the dynamicity efficiently is indispensable. This paper presents the … …Journal of Computer Science, Vol. 13, Issue 5 · 17 May 2017 · 7,418 accessesView PDFCite
Research ArticleOpen accessIn the author namesThe Effect of RSA Exponential Key Growth on the Multi-Core Computational ResourceMohamad A. Mohamed, Ammar Y. Tuama, Mokhairi Makhtar et al.Cryptography has been widely used as a mean to secure message communication. A cryptosystem is made up of a publicly available algorithm and a secretly kept key. The algorithm is responsible for transforming the original message into something unintelligible. The result of losing the key or cracked algorithm can be catastrophic, where all secret communications will be known to adversaries. … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 25 Nov 2016 · 7,827 accessesView PDFCite
