Research ArticleOpen accessPhrase in the titleSCANNING ELECTRON MICROSCOPE IMAGING OF AMYLOID FIBRILSEisuke Takai, Gai Ohashi, Ryuichi Ueki et al.This study demonstrated the applicability of Scanning Electron Microscopy (SEM) for the observation of amyloid fibrils without staining. As model specimens, two types of amyloid fibrils with different shapes and chemical compositions were controllably synthesized from hen lysozyme. The apparent fibril widths in the SEM images were considerably larger than the original diameters analyzed by the conventional techniques of Transmission … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 1 · 1 Mar 2014 · 10,330 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleThe Effect of Citrullus colocynthis Pulp Extract on the Liver of Diabetic Rats a Light and Scanning Electron Microscopic StudyMohammad Khalil, Gamal Mohamed, Mohammad Dallak et al.Problem statement: The goal of the current investigation was to clarify the effects of Citrullus colocynthis pulp extract on the structure of the liver of diabetic rats at both light and scanning electron microscopic levels. Approach: Forty-eight adult male albino rats were equally allocated into four groups: Group1: control, Group 2: Citrullus colocynthis-treated, Group 3: diabetic rats and Group4: diabetic … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 3 · 30 Sep 2010 · 9,478 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleScanning Electron Microscopic Evaluation of Self-Compacting Concrete Spalling at Elevated TemperaturesMahmoud B. Alhasanat, Arabi N. Al Qadi, Omar A. Al Khashman, Ahmad DahamshehThis paper reports the effect of addition of Polypropylene (PP) fibers in the performance of Self-Compacting Concrete (SCC) under elevated temperatures. Various SCC mixtures were made with PP fiber at 0.0, 0.05, 0.10 and 0.15% by volume added. The specimens were exposed to elevated temperatures (200°C [392°F], 400°C [752°F] and 600°C [1112°F]). The microstructure of the matrix was investigated. This … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 7 Mar 2016 · 8,433 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleTHE IMPACT OF ANTIOXIDANTS ON INFLAMMATION AND OXIDATIVE STRESS MARKERS IN OSTEOARTHRITIS RAT MODEL: SCANNING ELECTRON MICROSCOPE INSIGHTSEl Hassan Heidar, FareedF Al Faya, Waleed N. Hassan et al.Osteoarthritis (OA) is characterized by degradation of matrix and destruction of articular cartilage. Articular chondrocytes are solely responsible for the production and maintenance of the extracellular matrix. Therefore, chondrocyte disruption is implicated in cartilage degeneration. Numerous studies have shown that antioxidant treatments are promising therapeutics in cases of OA. This study was designedto examine whether vitamin E protects rat articular … …American Journal of Pharmacology and Toxicology, Vol. 9, Issue 2 · 19 May 2014 · 7,616 accessesView PDFCite
Case ReportOpen accessIn the keywordsBacterial Biofilm Persistence in Human Jawbone Following Tooth Extraction: Implications of Surgical Debridement and Resident Population-Shift for Oral ImplantsStephen Nelson, Honghua Hu et al.Intra-radicular infection theory assumes that when an infected tooth is extracted, the main source of infection is removed and any residual contaminating bacteria are killed by the immune response, then normal healing ensues. This study investigated whether bacteria and bacterial biofilms persisted in deep bone space following tooth extraction. The study was conducted on two adult male patients seeking dental … …Current Research in Dentistry, Vol. 14, Issue 1 · 31 May 2023 · 6,861 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCharacteristics of Cut Head Hair: An Evidence in Criminal InvestigationsPol. Maj. Satina Polyiam, Pol. Lt. Sasithorn Boonmapa, Wuttichai Phae-Ngam, Pichet LimsuwanOne hot news occurred in Thailand one year ago was a 3-year-old girl was murdered and only a number of hair strands were found near her body and likely cut by a knife. Later some cut hairs were found at the cloth of the suspect. In this study, the authors would like to match the hairs found at the crime … …American Journal of Applied Sciences, Vol. 18, Issue 1 · 6 Oct 2021 · 14,375 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Varying Loads on Wear Behaviour of Constructional SteelAlo Francis Ireti, Emordi Ngozi, Kunle Michael Oluwasegun et al.This study examined the effect of varying loads on wear behaviour of Ife constructional steel. The wear measurements were determined under normal ranging from 5 to 25 N at interval of 5 N incremental. The morphology of the corroded samples were carried out using optical microscopy and Scanning Electron Microscopy (SEM). When a load of 5 N was used, the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 6 Feb 2018 · 7,574 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHemodynamic Catheters: The Reprocessing, Cleanliness and in vitro Biofilm Formation by Enterococcus faecium in a Continuous Flow ModelCleber Galdino da Silva, Edson Pires de Oliveira, Ednalva Miranda Guizi et al.Reprocessing single-use devices to cut costs is a common practice in hospitals around the world. In Brazil, there are few studies of reprocessing hemodynamic catheters and thus, this study aimed to evaluate the effectiveness of reprocessing hemodynamic catheters before and after biofilm formation in vitro using a continuous flow model. We used a sterility test and Scanning Electron Microscopy (SEM) … …American Journal of Infectious Diseases, Vol. 11, Issue 2 · 24 Jul 2015 · 7,808 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnnual Concentration Report and Emission Sources Analysis of the Air Pollutants Measured by the Air Quality Monitoring StationP Khaenamkaew, S. Raksawong, K. Wongsorntam et al.Problem statement: Air Quality Monitoring (AQM) station at Kasetsart University, Si Racha Campus, Thailand, was routinely monitor the annual concentrations and analysis the emission sources of the air pollutants in the area since 2007. The level of concentration CO, SO2, NOx and O3 were measured. PM10 concentration was measured by mean of TOEM method. The PM10 and TSP (manifold) filters … …American Journal of Environmental Sciences, Vol. 7, Issue 5 · 1 Oct 2011 · 6,733 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImprovement of the Thermal, Photo and Mechanical Properties of Poly (Vinyl Chloride) in Presence of Poly (Glycidyl Methacrylate)Abir S. Abdel-NabyProblem statement: Poly (vinyl chloride) suffers from poor heat stability. The thermal degradation of the polymer leads to the evolution of hydrogen chloride gas, extensive discoloration of the polymer and lowering of physical and mechanical properties. Approach: Binary blends of Poly (Vinyl Chloride) (PVC) and Poly (Glycidyl Methacrylate) (PGMA) have been prepared by solution blending aimed at the improvement of … …American Journal of Applied Sciences, Vol. 8, Issue 7 · 24 Jun 2011 · 7,374 accessesView PDFCite
