Research ArticleOpen accessIn the keywordsPCR Diagnosis for the Identification of the Virulent Gene of Salmonella in Poultry MeatD. K. Zhanabayeva, A. Y. Paritova, G. K. Murzakaeva et al.The purpose of this study was to conduct microbiological studies of poultry meat imported into Mongolia and establish the serotypes and plasmids of Salmonella and determine the virulence of the gene encoding antibiotic resistance and its transmigratory properties. The PCR molecular biological method was used and according to the results, Salmonella enteritidis was identified in chicken carcasses of the American … …OnLine Journal of Biological Sciences, Vol. 21, Issue 3 · 27 Aug 2021 · 6,872 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Effects of Costus Root Aqueous Extract against Schistosomiasis, Liver Damage and Oxidants in Mouse Models of Schistosoma mansoni InfectionAreej Jameel M. AlghabbanSchistosomiasis is one of the major human parasitic diseases in many developing countries that causing chronic ill health in humans. The present work aimed to study the possible curative role of Costus (Saussurea lappa) root extract against Schistosoma mansoni infection induced liver toxicity, cytokines, oxidative stress and DNA damage in mice. 40 adult male micewere divided into four groups (G1, … …OnLine Journal of Biological Sciences, Vol. 21, Issue 2 · 15 Apr 2021 · 6,411 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBarcode of Life Data Systems (BOLD) Versus GenBank Molecular Identification of a Dragonfly from the UAE in Comparison to the Morphological IdentificationNoora Almansoori, Mohamed Rizk Enan, Mohammad Ali Al-DeebDragonflies are insects in the order Odonata. They inhabit freshwater ecosystems and are found in the UAE. To date, few checklists have been published for the local dragonflies and the used identification keys are not comprehensive of Arabia. The aim of this study was to provide a molecular identification of a dragonfly based on the mitochondrial Cytochrome c Oxidase subunit … …OnLine Journal of Biological Sciences, Vol. 19, Issue 4 · 30 Nov 2019 · 8,221 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMolecular Analysis of KRAS Mutation Associated with Colorectal Cancer in Iraqi PatientsRehab Subhi Ramadhan, Aola Sabah Ali, Rebah Najah AlgafariThe role of KRAS gene was investigated in manifestation of colorectal cancer in Iraqi patients. A total 40 blood samples were collected during October 2016 to January 2017 from AL-Amal Hospital in Baghdad and 20 blood samples from healthy subjects served as control. Blood samples were collected from subjects of 40-70 years old for both patients and control. The study … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 1 · 3 Mar 2018 · 9,027 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Investigation of Organelle Genomes of Extra Nuclear Sunflower Mutants with Variegated PhenotypeIrina Dremuk, Nikolay Kozel, Mariya Logacheva et al.The comparative analysis of complete chloroplast and mitochondrial DNA sequences of the original inbred line 3629 and three extra nuclear mutant lines variegated-1, variegated-15, variegated-17, obtained by the N-nitroso-N-methylurea induced mutagenesis, was done. The studied mutant lines were presented two different phenotypes with diverse chlorophyll content: Pale/green mutant line variegated-17 with 1.8% relative (to 3629 line) chlorophyll content in mutant … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 24 Oct 2017 · 7,638 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Deoxyribonucleic Acid Compression Algorithm Using Auto-Regression and Swarm IntelligenceWalid Aly, Basheer Yousif, Bassem ZohdyDNA compression challenge has become a major task for many researchers as a result of exponential increase of produced DNA sequences in gene databases; in this research we attempt to solve the DNA compression challenge by developing a lossless compression algorithm. The proposed algorithm works in horizontal mode using a substitutional-statistical technique which is based on Auto Regression modeling (AR), … …Journal of Computer Science, Vol. 9, Issue 6 · 30 May 2013 · 6,734 accessesView PDFCite
Research ArticleOpen accessIn the keywordsUse of Quinolones in Bull Semen Extenders to Reduce Sperm Deoxyribonucleic Acid DamageClara Gonzalez-Marin, Michael Eduard Kjelland, Rosa Roy et al.Cryopreserved sperm samples from Holstein bulls (n = 20) were examined for bacterial presence and Sperm DNA Fragmentation (SDF) dynamics. SDF was assessed after thawing (T0) and at 4, 24 and 48 h of incubation (37°C) and the rate of SDF (r-SDF), as an estimator of the DNA degradation over time, was calculated. Two groups of bulls were identified based … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 4 · 29 Dec 2012 · 7,433 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSimulation of Parallel Logical Operations with Biomolecular ComputingMahnaz Kadkhoda, Ali A. PouyanBiomolecular computing is the computational method that uses the potential of DNA as a parallel computing device. DNA computing can be used to solve NP-complete problems. An appropriate application of DNA computation is large-scale evaluation of parallel computation models such as Boolean Circuits. In this study, we present a molecular-based algorithm for evaluation of Nand-based Boolean Circuits. The contribution of … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 6,692 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGenetic Algorithm Based Probabilistic Motif Discovery in Unaligned Biological SequencesM. Hemalatha, K. VivekanandanFinding motif in biosequences is the most important primitive operation in computational biology. There are many computational requirements for a motif discovery algorithm such as computer memory space requirement and computational complexity. To overcome the complexity of motif discovery, we propose an alternative solution integrating genetic algorithm and Fuzzy Art machine learning approaches for eliminating multiple sequence alignment process.

Research ArticleOpen accessIn the keywordsAssessment of Genotoxic Activity of Para-nitrophenol in Higher Plant Using Arbitrarily Primed- polymerase Chain Reaction (AP-PCR)Mohamed R. EnanParanitrophenol is a common toxic environmental pollutant; the aim of this study was to evaluate the potential of the DNA fingerprinting by AP-PCR assay to detect the DNA damage in the common bean (Phaseolus vulgaris) exposed to different concentrations of paranitrophenol (4.0-720 nM). The changes occurring in the fingerprint patterns were likely to be the result of paranitrophenol-induced DNA damage. … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 2 · 30 Jun 2007 · 7,069 accessesView PDFCite
