Research ArticleOpen accessIn the author namesHigh Frequency of Stop Codons in the Human Immunodeficiency Virus-1 Protease Gene Frame in Human Immunodeficiency Virus+ Individuals with Below Detectable Levels of Plasma Viremia During Highly Active Antiretroviral TherapyMagdalena Czubala, Kabo Matlho, Maria Arriaga et al.We performed sequence analysis of HIV-1 proviral protease gene fragment (560 base pairs) amplified from ex-vivo peripheral blood mononuclear cells of 83 HIV+ individuals with Below Detectable Levels (BDL) (<20-40 RNA copies/ml plasma) and detectable levels of plasma HIV viremia while on HAART. Noteworthy was the systematic presence of stop codons identified only in the BDL group and not in … …American Journal of Infectious Diseases, Vol. 8, Issue 3 · 14 Nov 2012 · 8,075 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification and Pathogenicity of the Soybean Root Rot Pathogen in Arid ConditionsNurlan Kuldybayev, Yerlan Dutbayev, Olga Konstantinova et al.Soy is an important oilseed crop in Kazakhstan. However, its yield is significantly reduced due to an increase in the development of fungal diseases with soil infection. This study aims to identify the root rot pathogen in soybean varieties in Western Kazakhstan and assess its pathogenicity. Samples of soybean roots to determine the root rot pathogen were selected at the … …OnLine Journal of Biological Sciences, Vol. 23, Issue 2 · 14 Apr 2023 · 5,528 accessesView PDFCite
Review ArticleOpen accessIn the abstractA Brief Review of the Latest Advances of Attapulgite as a Reinforcing Agent in Polymer Matrix NanocompositesThais Ferreira da Silva, Gabriel Portilho Monteiro de Souza, Guilherme Ferreira de Melo Morgado et al.The development of polymeric nanocomposites using clay minerals as a Nano filler is of great interest to researchers and industry. Many clay minerals are used to modify the properties of the polymers; this strategy improves the thermal and mechanical performance and changes the surface finishing and the processing characteristics. The Attapulgite (ATP), which is a clay mineral of the hydrated … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 2 · 3 Jun 2021 · 7,425 accessesView PDFCite
Research ArticleOpen accessIn the abstractReprocess of Copper from Worn Printed Circuit BoardsSwarnambiga A.K., M. Vidya Kalaivani, Sarah Sathyawathi, T.S. Ramyaa LakshmiThe objective of the study is to reuse printed circuit boards which are mainly made of copper. Most top down and bottom up approaches for the synthesis of Copper nanoparticles (CuNPs) needs pure copper (II) sulfate or any other copper salts as a raw material. For the expensive non-ecofriendly reasons, here we used wasted Printed Circuit Boards (PCBs) as an … …OnLine Journal of Biological Sciences, Vol. 19, Issue 1 · 12 Feb 2019 · 7,486 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntidiabetic and Antioxidant Potential of Vernonia amygdalina Leaf Extract in Alloxan-Induced Sprague-Dawley RatsFatmawaty Yazid, Nina Bonita Hasanah, Rosmalena et al.The treatment of diabetes mellitus using drug medications have side effects such as weight gain, hypoglycemia, the risk of cardiovascular or all-cause mortality. These limitations have become one reason to use complementary therapy from plant extract, such as Vernonia amygdalina as an antidiabetes. This research aimed to investigate the effect of V. amygdalina leaf extracts as antidiabetic and antioxidant agents … …OnLine Journal of Biological Sciences, Vol. 20, Issue 4 · 23 Nov 2020 · 8,656 accessesView PDFCite
Research ArticleOpen accessIn the abstractOne Real-Time Fluorescent Loop-Mediated Isothermal Amplification Combined with Propidium Monoazide for Detection of Viable Vibrio Parahaemolyticus in SeafoodHuanteng Yu, Jiehong Fang, Biao Ma et al.Vibrio parahaemolyticus is one of the crucial foodborne pathogens in the world. At present, the rapid detection methods for V. parahaemolyticus cannot distinguish between dead and viable cells and false positive results may occur. In this study, one rapid and accurate method that combines Propidium Monoazide (PMA) with real-time fluorescent loop-mediated isothermal ampli?cation (LAMP) using SYTO-16 dye was developed to … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 2 · 26 Jun 2019 · 7,593 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomatic Counting for Live and Dead Cells from Trypan Blue-Stained Images by Image Analysis Based on Adaptive K-Means ClusteringSu Mon Aung, Kanyanatt Kanokwiroon, Tonghathai Phairatana, Surapong ChatpunComputer-assisted image analysis can be employed to reduce the time consumed in the routine task such as cell counting. This study aimed to establish a method to perform this routine task based on an image analysis to automatically count live and dead cells after staining with trypan blue dye. Gray scale conversion and morphological operation were applied to the input … …Journal of Computer Science, Vol. 15, Issue 2 · 1 Mar 2019 · 8,571 accessesView PDFCite
Research ArticleOpen accessIn the abstractTaxifolin Potently Diminishes Levels of Reactive Oxygen Species in Living Cells Possibly by Scavenging Peroxyl RadicalsSatoru Sakuma, Yui Kishiwaki, Mayu Matsumura et al.Taxifolin, a naturally occurring dihydroflavonol, has been reported to possess antioxidant activity, whereas there is little information regarding its antioxidant potency as a flavonoid. In the present study, the antioxidant efficacy of taxifolin in living cells was compared to that of catechin, a potent radical scavenger, by using flow cytometry with the redox-sensitive fluorescent dye, 2′,7′-dichlorodihydrofluorescein diacetate. Further, diminishing efficacy … …American Journal of Pharmacology and Toxicology, Vol. 13, Issue 1 · 18 Oct 2018 · 8,058 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhotostability of Ponceau 2R Doped Thin Film Sol-Gel Silica as Luminescent Solar CollectorS.M. RedaProblem statement: Current researches had shown that the photostability of a luminescent solar collector depend on the method of its preparation and type of using dye. This research therefore aimed at studying the stability of luminescent solar collector prepared by sol-gel spin coating method using Ponceau 2R. Approach: The effect of silica matrix on the photostability and fluorescence properties of … …Energy Research Journal, Vol. 1, Issue 1 · 30 Jun 2010 · 7,224 accessesView PDFCite
Research ArticleOpen accessIn the abstractTartaric Acid Modified Rice Hull as a Sorbent for Methylene Blue RemovalSiew-Teng Ong, Pei-Sin Keng, Ai-Wen Chong et al.Problem statement: Improper dye discharge from various industries such as textile, paper, cosmetic and plastics into receiving streams can be one of the sources towards water pollution.
