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 · 6,409 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBiotic and Abiotic Factors of Sperm nDNA Fragmentation in Farm AnimalsBaylar Iolchiev, Natalya Volkova, Pavel Klenovitskiy et al.Infertility and subfertility are among the global challenges of our time. Fertility in livestock farming is not only biologically important, it is also economically important. The aim of this study was to study the effect of these factors on sperm chromatin nucleus and to assess the impact of the fragmentation index degree on bull reproductive performance. The influence of abiotic … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 11 Mar 2021 · 6,714 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 · 8,213 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 · 9,024 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 · 7,633 accessesView PDFCite
Research ArticleOpen accessIn the keywordsValidation of SSR markers associated with Submergence Tolerance in Rice (Oryza sativa L.)Kirill V. Azarin, Alexander V. Usatov, Andrey V. Alabushev et al.The present work is devoted to the validation of SSR markers associated with submergence tolerance (Sub1A) QTLs in rice. It was shown that only microsatellite markers RM 7481 differentiates donor lines and recipient variety. Based upon the results of DNA analysis with the marker of the RM 7481 of the F2-plants, the 14 homozygotes by the locus Sub1A, 40 samples … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 19 Dec 2016 · 7,634 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSwarm Optimization Techniques for Segmenting Gel Electrophoresis ImagesSara Ibrahim Ibrahim, Mohamed Abd Allah Makhlouf, Ghada.S. El-Tawel, M.E. WahedGel Electrophoresis (GE) are discussed as the main tool to dissociate DNA sequences. It helps in analyzing the genome such that each image resulting from it consists of lanes that include several bands. Image segmentation plays the foremost role in image processing. It helps in producing accurate results in medical diagnosis. Image segmentation works by dividing an image into regions … …Current Research in Bioinformatics, Vol. 5, Issue 1 · 18 Jun 2016 · 8,092 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 · 6,729 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 · 7,430 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOne-Sided Multivariate Tests for High Dimensional DataSamruam ChongcharoenProblem statement: For a multivariate normal population with size smaller than dimension, n<p, the likelihood ratio tests of the null hypothesis that the mean vector was zero with a one-sided alternative were no longer valid because they involved with sample covariance matrix which was singular. Approach: The test statistics for one-sided multivariate hypotheses with n<p were proposed. Results: The simulation … …Journal of Mathematics and Statistics, Vol. 8, Issue 2 · 20 Jun 2012 · 7,261 accessesView PDFCite
