Research ArticleOpen accessIn the abstractMycobacterium tuberculosis Complex Mutations in Drug Resistant Clinical Isolates from Southwest MexicoMartínez-Cruz Perla Mónica, Nakamura-López Yuko, Quintero-Hernández Verónica et al.Mutations in target genes have been described in Mycobacterium tuberculosis Complex (MTBc) drug resistant isolates worldwide. In Mexico, not enough information has been reported in this concern. The aim of this study was to characterize mutations related to resistance to first line drugs in MTBc isolates from Oaxaca, Mexico. MTBc isolates were identified in clinical samples from Tuberculosis (TB) patients. … …American Journal of Infectious Diseases, Vol. 17, Issue 4 · 28 Oct 2021 · 6,669 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Feed Additive Supplementation on Growth Performance, Intestinal Morphology, Intestinal Microflora and Nutrient Digestibility Study of Broiler ChickenSunday Egba Omogo, Emeka Henry Oparaji, Franklin Uzodinma EdejiThe present study evaluated the effect of various feed additive supplementation on growth performance, intestinal morphology, intestinal microflora and nutrient digestibility study of starter broiler chicks. A day-old broiler chicks with total number of two hundred and four (204) (Ross 308) were randomly allotted to eight (8) dietary treatments with four (4) replicate pens per treatment (average of 6 birds … …American Journal of Applied Sciences, Vol. 18, Issue 1 · 7 May 2021 · 8,342 accessesView PDFCite
Research ArticleOpen accessIn the abstractPlant Growth Promoting Activity of Actinomycetes Isolated from Soybean RhizosphereAris Tri Wahyudi, Jepri Agung Priyanto, Resti Afrista et al.Plant Growth Promoting Rhizobacteria (PGPR) is considered as the biological agent for improving plant growth. One Group of PGPR that have an important role in growth promoting of plant is Actinomycetes. The objective of this study was to isolate and screen Actinomycetes isolated from soybean rhizosphere as growth promoter of soybean in vitro. Fifty-three Actinomycetes isolates have successfully been isolated … …OnLine Journal of Biological Sciences, Vol. 19, Issue 1 · 5 Jan 2019 · 14,613 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe -863 TNF-α Polymorphism and Primary Open Angle Glaucoma in EgyptiansWalaa Bayoumie Abdulwahhab El Gazzar, Shaymaa Mohamed Abd El Rahman, Mohamed Nagy Elmohamady et al.Growing evidence indicates that TNF-alpha is involved in the pathogenesis of POAG in several ways, primarly by induction of retinal ganglion cells apoptosis and therefore optic nerve degeneration. TNF-alpha and POAG relationship has been studied at the genetic level with variable results in different populations. The transcription rate and the release of the TNF-alpha cytokine have been reported to be … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 2 · 1 Jun 2017 · 7,360 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Cadmium on Worker Ovary Morphology of Bombus morio (Hymenoptera: Bombini)Fábio Camargo Abdalla, Marina Pedrosa, Caio Eduardo da Costa Domingues, Paulo José BalsamoBees are valuable bioindicators, providing information regarding environmental conditions through different kinds of analyses. Therefore, the effect of cadmium on the morphology of ovaries of Bombus morio workers was used to study a concentration considered environmentally safe (1 ppb) in Brazil. Workers of the same estimated age exposed for 48 h to 1 ppb cadmium showed extensive morphological changes in … …American Journal of Agricultural and Biological Sciences, Vol. 13, Issue 1 · 10 Apr 2018 · 9,143 accessesView PDFCite
Research ArticleOpen accessIn the abstractRelative Transcription Expression Level of SIRT1, SIRT2 and SIRT3 in Correlation to the Expression of a Set of Selected Cancer Related Genes in Human Breast CancerHamdy Swelim, Omnia Mansour, Salah Abdel-Rahman et al.Mammalian Sirtuins have been shown to perform distinct cellular functions and deregulated expression of these genes was reported to be involved in the development of various malignancies including breast cancer. An increasing number of evidence indicates that Sirtuins have both tumor promoter and tumor suppressor functions. However, the roles of Sirtuins have not been well-studied in breast cancer. In the … …OnLine Journal of Biological Sciences, Vol. 18, Issue 2 · 18 Jan 2018 · 7,479 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeterologous Expression and Characterization of Thermostable Levansucrase (BsSacB) from Bacillus subtilis BB03Viniti Vaidya, Gajjeraman Prabu, D. Theertha PrasadThermostable levansucrase encoding gene (sacB) with its promoter was isolated from Bacillus subtilis BB03. BsSacB is composed of 1419 bp, encoding 473 amino acid residues and with promoter regions TTGCAA (-35) and TAGAAT (-10). The amino acid sequence analysis of BsSacB showed conserved motifs of microbial fructosyltransferase belonging to Glycoside Hydrolase family 68 (GH68). Comparative analysis of the protein structure … …OnLine Journal of Biological Sciences, Vol. 15, Issue 1 · 25 Mar 2015 · 7,376 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancement of Nutritional Quality of Wheat (Triticum aestivum) by Metabolic Engineering of Isoflavone PathwayAhmed Mohamed El-Shehawi, Abdelmegid Ibrahim Fahmi, Mona Mohamed Elseehy, Hesham Ahmed NagatyIsoflavones are large group of secondary metabolites produced in legumes such as soybeans. They have essential biological functions as nutraceutical and health functions for human. They are involved in plant resistance to biotic and abiotic stresses, symbiotic relationship with nitrogen-fixing organisms and plant competition (allelopathy). In this report, isoflavonoids were expressed in wheat (Triticum aestivum) via introducing the key enzymes … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 7,139 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetection of Polymorphism at the Insulin Like Growth Factor-I Gene in Mazandaran Native Chicken using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism MethodHossein Ali Abbasi, Mohsen KazemiProblem statement: Molecular genetics selection on individual genes is a promising method to genetically improve economically important traits in chickens. The Insulin like Growth Factor-I (IGF1) gene may play important roles in growth of multiple tissues, including muscle cells, cartilage and bone. Approach: In the present study polymorphism of the promoter and 5' untranslated region of IGF-1 gene of Mazandaran … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 2 · 8 Aug 2011 · 7,634 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Arid3a Transcription Factor Rescues Natural and RAS-V12-Induced Senescence Via a Rb-Dependent PathwayChristian Schmidt, Dongkyoon Kim, Shawn Mathur et al.Primary cells are protected against oncogenic events by undergoing premature cellular senescence—an irreversible cell cycle arrest activated by mitogenic signaling as well as by overexpression of tumor suppressors, including p16INK4A, p53 and PML. In the human, downregulation of Dril1/E2F-BP1, a transcriptional regulator of E2F, promotes PML-dependent premature senescence and bypass of ant-iproliferative signaling by p19Arf/p53/p21Cip1 and p16INK4a to prevent both … …American Journal of Immunology, Vol. 13, Issue 4 · 4 Nov 2017 · 8,397 accessesView PDFCite
