Research ArticleOpen accessEvery word in the titleIntrahydrogen Bonding and Transition States Between Enol and Enethiol Tautomers in β-ThioxoketonesBahjat A. Saeed, Rita S. Elias, Ebraheem Abdu MusadProblem statement: Hydrogen bonding is one of the most important concepts in chemistry because it is crucial to understand many different interactions both in gas phase and in condensed media. A particular subset is presented by the intramolecular hydrogen bonds where two ends of the same molecule interact, resulting in a ringlike structure. Approach: The study involved theoretical investigation of … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 18 Jul 2011 · 7,452 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBonding of Resin Materials to All-Ceramics: A ReviewLiang Chen, Byoung In SuhProblem statement: All-ceramic materials, especially silica-based lithium disilicate and non-silicate-based Zirconia, have become a topic of interest in the field of dentistry. It is still difficult to achieve a strong and durable resin-ceramic adhesion, especially resin-Zirconia bonding. Approach: The article reviews the current literature published in the past 5 years, focusing on the latest resin bonding techniques (including surface treatment, … …Current Research in Dentistry, Vol. 3, Issue 1 · 21 May 2012 · 15,814 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHydrophobic, Polar and Hydrogen Bonding Based Drug-Receptor Interaction of TetrahydroimidazobenzodiazepinonesV.K. Sahu, A.K.R. Khan, R.K. Singh, P.P. SinghAnti-HIV drug discovery has been increasingly focusing on HIV-1-RT (reverse transcriptase) as a potential therapeutic target. Tetrahydroimidazobenzodiazepinone (TIBO) belongs to non-nucleoside group of reverse transcriptase inhibitors (NNRTIs). A computational chemistry study has been performed on a series of tetrahydroimidazo-benzodiazepinones as HIV-1-NNRT inhibitors. Problem statement: In order to search out new drug of desired activity from the lead compounds, there was … …American Journal of Immunology, Vol. 4, Issue 3 · 30 Sep 2008 · 8,837 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBonding Property of Bituminous Crack Sealants in the Presence of WaterEllie Fini, Taher Abu-LebdehProblem statement: Crack sealing and filling is the most widely used maintenance activity for in-service pavements. If an appropriate sealant material is selected and properly installed at the appropriate time of the pavement life, it retards pavement deterioration and increases its service life at a relatively low cost. However, in some cases it is reported that sealants failed prematurely, mainly … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 12 Mar 2011 · 8,338 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCulture and the Changing Food Consumption Among the Malay Middle ClassKartini Aboo Talib, Zaireeni Azmi, Hanim Ismail, Nurul Asmaa RamliThis article examines the consumption of foods among the middle-class Malays in Malaysia and the progress of food products that have been constructed to meet the halal logo and certification. This article challenges the standard view of the Malay middle class, predominantly Muslim that they are traditional and hesitant to accept changes in food consumption due to religion and culture. … …Journal of Social Sciences, Vol. 18, Issue 1 · 2 Mar 2022 · 8,078 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTheoretical Study of the Proton Transfer in EnaminonesRita Sabah EliasProblem statement: Hydrogen bonding has a vital rule to unrevealed the nature of many different interactions both in gas phase and condensed media thus it is one of the most important concepts in chemistry. Enaminoes with their ability to form intrahydrogen bonded cheated rings represent one of the suitable compounds to study such concept. Approach: The three possible tautomers of … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 23 Nov 2011 · 7,418 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDetection of Subsurface Defects in Concrete Bridge Deck JointsWonchang Choi, Larry Rickard, Taher Abu-Lebdeh, Miguel PicornellProblem statement: The integrity of deck joints in highway bridges plays a major role to determine overall performance of bridge system. As the bridge maintenance program, the defects in deck joints have historically been detected by conventional non-destructive testing and evaluation methods such as visual inspection, chain-dragging and by the detecting sounds under the traffic. Future bridge maintenance challenges will … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 31 Dec 2011 · 7,772 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBinding Studies of Natural Product Berberine with DNA G-QuadruplexNagendra K. Sharma, Pooja Lunawat, Manjusha DixitProblem statement: The ends of chromosome had highly repetitive short G and C-rich sequences of DNA. These sequences were known to form stable tetraplex type of secondary structures which help to maintain gene integratity after cell divison. Approach: Any reagent which controls the random cell division would be useful to design anticancer drugs. Therefore a many natural and synthesized molecules … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 3 · 22 Sep 2011 · 8,797 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalysis of Resistance to Human Immunodeficiency Virus Protease Inhibitors Using Molecular Mechanics and Machine Learning StrategiesA. Harishchander, D. Alex Anand, Sanjib SenapatiProblem statement: Drug resistance is the most important factor, which influences the failure of current HIV therapies. So, the ability to predict the drug resistance of HIV-1 protease mutants will be useful in developing more effective and longer lasting treatment regimens. Approach: Drug resistance of HIV-1 protease is predicted with two current protease inhibitors (Indinavir and Saquinavir). The problem was … …Current Research in Medicine, Vol. 1, Issue 2 · 31 Oct 2010 · 7,204 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of the Contribution of Late Embryogenesis Abundant (LEA) K Peptide in Enhancing the Expression of Lipase from Sphingobacterium sp.: In vitro and in Silico StudiesIbrahim Muhammad et al.Sphingobacterium sp. AB3 lipase is a psychrophilic enzyme with optimal lipolytic activity at pH 7 and 15°C. The cold-adapted properties of the lipase render it suitable for various low-temperature industrial applications such as biodiesel production, detergent formulation, and non-thermal food processing. Recent studies have shown that co-expression of LEA K peptide with AB3 lipase resulted in enhanced protein expression in … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 4 · 21 Nov 2024 · 4,569 accessesView PDFCite
