Research ArticleOpen accessIn the keywordsInfluence of Triethanolamine on the Chemical Bath Deposited NiS Thin FilmsAnuar Kassim, Ho Soon Min, Tan Wee Tee, Ngai Chee FeiProblem statement: Recently, many scientists looking for new chalcogenide materials for the solar cell applications. Nowadays, silicon-based solar cell became dominant products in the market. Because of expensive silicon-based solar cells, scientists hope replaces it with cheaper chalcogenide materials. Approach: The binary chalcogenide materials were deposited onto microscope glass slide using simple chemical bath deposition method. Here, we study the … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,970 accessesView PDFCite
Research ArticleOpen accessIn the keywordsUltrastructural Changes in the Ileum of White BALB/C Mice Experimentally Infected with Salmonella hadarAfaf Abdulrahman Yousif, Maan M. Neima AL-NaqeebProblem statement: Recently, Salmonella hadar has been isolated and identified from goat in Iraq. The purpose of the present study was to investigate the ultrastructural changes in the ileum epithelial cells of mice experimentally infected with Salmonella hadar. Approach: The white BALB/c mice inoculated orally with Salmonella enterica serovar hadar strain and their ileums were examined by transmission electron microscopy … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 7,113 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDetection of HCV Components and Pathological Reactions in Apoptotic Hepatocytes from Chronically HCV-infected PatientsViviana Falcón, Nelson Acosta-Rivero, Mineko Shibayama et al.Analysis of Hepatitis C Virus (HCV)-infected hepatocytes at the cellular level may contribute to elucidate the mechanisms of HCV pathogenesis. In this work, the presence of HCV components and pathological reactions in apoptotic hepatocytes from chronic HCV-infected patients were studied by electron microscopy and confocal microscopy. Eight samples of liver biopsies from patients with chronic hepatitis C were studied by … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 6,907 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Lead on the Chlorophyll and Antioxidant Response in the Leaves of Arabidopsis thalianaJun Xing, Cailing Yuan, Hui Yu et al.Lead (Pb) is a non-essential heavy metal element for plants. In this study, the effect of 0.025, 0.05, 0.1, 0.25, and 0.5 g/L Pb on the chlorophyll and antioxidant response was analyzed in the leaves of Arabidopsis thaliana. The results indicate that 0.025 g/L Pb had no significant effect on the fluorescence intensity of chlorophyll. However, 0.05, 0.1, 0.25, and … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 1 · 31 Mar 2024 · 4,628 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Novel Method for the Non-Destructive Assessment of Strength Degradation and Re-Use Potential of Weathered Float Glass From Facades: A Proof of Concept StudyFred Veer, Mauro Overend, Irene Sofokleous, Chris NoteboomLack of knowledge about the properties of weathered (used) glass is currently a major barrier to glass reuse. This results in probably unnecessary recycling or down-cycling of architectural glass at the end of life. Avoiding this creates a significant opportunity to reduce resource depletion and decarbonize the built environment. This can be done by developing an optical non-destructive test method … …International Journal of Structural Glass and Advanced Materials Research, Vol. 7, Issue 1 · 19 Oct 2023 · 9,292 accessesView PDFCite
Research ArticleOpen accessIn the keywordsLANGMUIR-BLODGETT NANOTEMPLATE CRYSTALLIZATION COMBINED TO LASER-MICROFRAGMENTATION UNIQUELY CHARACTERIZE PROTEINS CRYSTALS BY SYNCHROTRON MICRODIFFRACTIONClaudio Nicolini, Luca Belmonte, Christian Riekel et al.Laser-induced microfragmentation of LB nanotemplate-induced protein crystals in glycerol solution results in distinct, coherently diffracting domains. Only crystals produced according to the Langmuir-Blodgett (LB) nanotemplate technique reveal in all four proteins being tested (lysozyme, insulin, thaumatin and ribonuclease) domains highly radiation resistant, while the crystals produced by the standard hanging drop crystallization method do not. Actually the very same laser … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 1 · 11 Feb 2014 · 7,984 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHost Pathogen Interaction Study in Malformed Affected Tissues of Mangifera indica L.Pradeep Kumar, Madhu Kamle, Vijai Kumar Gupta et al.The malformation disease of mango by Fusarium moniliforme var. subglutinan is one of the major causes of huge economical loss every year. Early diagnosis of the pathogens can help cultivators to protect the mango orchid and fruits from successive and secondary infection. The molecular detection is one of the better choices among available techniques for diagnosis. But the farmers or … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 3 · 4 Sep 2013 · 7,919 accessesView PDFCite
Research ArticleOpen accessIn the keywordsUltrastructural Evidences of Hepatitis B Infection in Human Liver Biopsies Disclose Complex Assembly and Morphogenesis Pathways for Hepatitis B VirusViviana Falcon, Ivon Menéndez, Nelson Acosta-Rivero et al.Despite of recent advances on acknowledge of hepatitis B virus (HBV) structure and biology, little is known about the morphogenesis and release of virions. In this study, the ultrastructural analysis of HBV components in liver biopsies from chronically HBV-infected patients disclosed complex assembly and morphogenesis pathways for HBV. HBV core (HBcAg) and surface (HBsAg) antigens were specifically identified in all … …American Journal of Infectious Diseases, Vol. 4, Issue 2 · 30 Jun 2008 · 7,091 accessesView PDFCite
Research ArticleOpen accessIn the keywordsStudy of the Mandibular Glands of Ant Workers Atta sexdens rubropilosa (Forel, 1908) (Hymenoptera: Formicidae) Focusing the Ultrastructural CytochemistryLorena Favaro Pavon, Maria Izabel Camargo MathiasThe mandibular glands of hymenopterans in general are paired structures located on each side of the head. These glands possess an excretory duct located at the internal surface of the mandible articulation, through which these glands release the secretion they produce. The mandibular glands of the minima, media and soldier worker of the ant Atta sexdens rubropilosa were analyzed by … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 2 · 30 Jun 2006 · 7,643 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEvidences of Apoptosis in Hepatitis C Virus-Infected Hepatocytes and Peripheral Blood Monocuclear Cells in the Absence of Liver InjuryViviana Falcón, Nelson Acosta-Rivero, Mineko Shibayama et al.Understanding the mechanism of Hepatitis C Virus (HCV) pathogenesis is an important part of HCV research. In this study, the presence of apoptosis in HCV-infected liver and Peripheral Blood Mononuclear Cells (PBMC) from patients positive for anti-HCV antibodies and negative for serum HCV-RNA was investigated.
