Research ArticleOpen accessEvery word in the titleAnalysis of the Utility of MPT64, Drug Susceptibility Testing and Tuberculosis/Nontuberculous Mycobacteria Reverse Transcription Polymerase Chain Reaction for Tuberculosis Diagnosis and Efficiency Compared with Traditional CultureHo Keun Choi, Ga Yeon Kim, Tae Soung Kim, Jae Kyung KimDefining the molecular mechanisms underlying the dormant state of Mycobacterium tuberculosis (MTB) is essential for developing more effective treatments for tuberculosis (TB) infection. We investigated the positivity and resistance rates of TB tests on 6,174 samples referred to a single hospital. Of these, 342 cases (5.5%) were confirmed as positive by acid-fast bacilli staining, 243 cases (71.1%) were detected as … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 4 · 5 Dec 2024 · 4,206 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAutomatic Piano Sheet Music Transcription with Machine LearningFernandes Saputra, Un Greffin Namyu, Vincent et al.Automatic Music Transcription (AMT) is becoming more and more popular throughout the day, it has piqued the interest of many in addition to academic research. A successful AMT system would be able to bridge multiple ranges of interactions between people and music, including music education. The goal of this research is to transcribe an audio input to music notation. Research … …Journal of Computer Science, Vol. 17, Issue 3 · 4 Mar 2021 · 9,248 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHigh Level of Nicotianamine Synthase (NAS3) and Natural Resistance Associated Macrophage Protein (NRAMP4) Gene Transcription Induced by Potassium Nitrate in Trembling Aspen (Populus tremuloides)Karolina M. Czajka, Kabwe NkongoloChanges in gene transcription in response to excess metal concentrations have been reported in many organisms, including yeast, microorganisms and plants. Most investigations on the effects of nickel toxicity in plants use commercial salts whose effects have not been analyzed in detail. The main objective of the present study was to determine the effects of different doses of nickel nitrate … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 3 · 15 Jul 2018 · 10,884 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDifferential Gene Transcription in Red Oak (Quercus rubra) Genotypes Resistant to Copper ToxicityProulx Migueal, Paul Michael, Charnelle Djeukam, Kabwe NkongoloToxicity of metals is a major abiotic stressor of plants. Copper (Cu) is one of the most abundant metals in soils from the Greater Sudbury Region (GSR) due to its mining history. Recent studies have described several transporters and chelating proteins involved in copper resistance. Quercus rubra (Red Oak) is a common species that grows in metal contaminated soils in … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 11 Dec 2017 · 8,545 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInhibition of U6 snRNA Transcription by PTENStephanie Cabarcas, Kounosuke Watabe, Laura SchrammProblem statement: RNA polymerase III (RNA pol III) is responsible for transcribing many of the small structural RNA molecules involved in RNA processing and protein translation, thereby regulating the growth rate of a cell. RNA pol III transcribes both gene internal (tRNA) and gene external (U6 snRNA) promoters and proper initiation by RNA polymerase III requires the transcription initiation factor … …OnLine Journal of Biological Sciences, Vol. 10, Issue 3 · 30 Sep 2010 · 8,551 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAssessment of Site Specific Mutational Effect on Transcription Initiation at Escherichia coli PromoterS. Kannan, M. Krishnan, S. Sundarraj et al.Problem statement: It is widely accepted thought that the weak promoters control the RNA synthesis and play regulatory role in complex genetic networks in bacterial system. An experiment had been designed to address whether mutations in the -16/-17 region affect the rate of transcription at an activator-independent promoter in E. coli or not? Approach: The aim of this study was … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 2 · 30 Jun 2009 · 7,555 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Novel Heat Shock Transcription Factor Family in Entamoeba histolyticaConsuelo G. García, Ma. De la Luz Macias Argüelles, D. Guillermo P Ishiwara et al.The HSTF is a master molecule involved in the transcriptional control of several genes during different types of stress. This transcription factor is a very conserved protein identified in different organisms from bacterial to human. Entamoeba histolytica is the protozoan responsible for the human amoebiasis. This parasite is exposed to different kind of stress as changes in the pH, temperature, … …American Journal of Infectious Diseases, Vol. 3, Issue 2 · 30 Jun 2007 · 7,182 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePDX-1 and MafA: Key Transcription Factors in PancreasHideaki Kaneto, Takeshi Miyatsuka, Yoshihisa Nakatani, Taka-aki MatsuokaPancreatic and duodenal homeobox factor-1 (PDX-1) plays a crucial role in pancreas development, β-cell differentiation and in maintaining normal β-cell function by regulating several β-cell-related genes including insulin. PDX-1 has potency to induce insulin-producing cells in non β-cells in various tissues such as pancreas and liver and PDX-1-VP16 fusion protein more efficiently induces insulin-producing cells, especially in the presence of … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 7,389 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe 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 · 8,396 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleRole of Cytokines and Transcription Factors in Periodontitis: A Review of Cellular and Molecular MechanismsAnne Carolina Eleutério Leite, Valéria Martins de Araújo Carneiro, Júlia Faria Nunes et al.Periodontal Diseases (PD) are characterized by pathological manifestation of host immune response to bacterial infection at the tooth/gingival interface. Evidences points periodontitis as a risk factor for pathological systemic conditions, such as, cardiovascular diseases and diabetes. The identification of host factors that determine their susceptibility to immune subversion can provide useful information in the pathogenesis of periodontitis.
