Research ArticleOpen accessIn the abstractIntroducing Radio-Opaque Radio-Lucent Graduated Root Canal Length Indicating Cones (GRCLIC) in EndodonticsMohammad Rashid Shahidi BonjarRadio Opaque-Radiolucent Graduated Root-Canal Length Indicating Cone (GRCLIC) is a new innovative device being introduced for the first time in endodontics literature. GRCLIC can present more accurate measurement of the root canal length in conventional radiographs in endodontic and root canal treatment. Like many other dental and medical specialties, endodontics has evolved and changed over the years. The changes that … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,095 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Characterization of Al Bond Pad Surface Treatment in Electroless Nickel Immersion Gold (ENIG) DepositionM.K. Md Arshad, A. Jalar, I. Ahmad, G. OmarThis study reports a number of experiments that were designed to characterize aluminum bond pad surfaces prior to electroless nickel immersion gold (ENIG). In the ENIG process, aluminum bond pads need special treatment to achieve successful nickel deposition and provide reliable interconnection of under bump metallurgy in advanced packaging. During this treatment process, the aluminum pad was cleaned, activated and … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,722 accessesView PDFCite
Research ArticleOpen accessIn the abstractCoronary Heart Disease (CHD) Risk Factors and Metabolic Syndrome in HIV-Positive Drug Users in MiamiMarianna K Baum, Carlin Rafie, Shenghan Lai et al.The frequency of coronary heart disease (CHD) is increasing among HIV seropositive persons. This phenomenon may be related to HIV disease itself, the use of antiretroviral medications and increased length of survival, or the synergism of these factors. In this study we have calculated the 10-year CHD risk estimate and the prevalence of metabolic syndrome in a cohort of 118 … …American Journal of Infectious Diseases, Vol. 2, Issue 3 · 30 Sep 2006 · 6,989 accessesView PDFCite
Research ArticleOpen accessIn the abstractPharmacodynamic Comparison of the Carbapenems Against E. coli and Klebsiella spp. Containing Extended spectrum β-lactamasesKathryn J. Eagye, Joseph L. Kuti, David P. NicolauCarbapenems are the treatment of choice for extended-spectrum β-lactamases (ESBLs). Ertapenem is a new member of the carbapenem class, and is often grouped with imipenem and meropenem as a recommended treatment for ESBLs. However, new in vitro data question ertapenem’s inclusion as a first line treatment for these bacteria, suggesting that ertapenem has a lower likelihood of obtaining appropriate pharmacodynamic … …American Journal of Infectious Diseases, Vol. 1, Issue 3 · 30 Sep 2005 · 6,886 accessesView PDFCite
Research ArticleOpen accessIn the abstractForensic Considerations of HIV Infected and Those at RiskB. R. Sharma, Sumedha BangarWhile HIV infection is considered protected information in most parts of the world, it is clear that if a health care provider knows, that the patient is infected or is likely to be infected, then either the patient or those responsible for making their medical decisions must be informed of the infection or likelihood of infection. If not, the liability … …American Journal of Infectious Diseases, Vol. 1, Issue 3 · 30 Sep 2005 · 6,450 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Different Doses of Irradiation on Oxidant and Antioxidant Systems in the Brain of Guinea PigsYildiz Guney, Ayse Bilgihan, Ayse Hicsonmez et al.The purpose of this study was to establish the impact of oxidative stress in the damaged brain tissue, irradiated with two different dose levels, a single dose of 8 and 15 Gy. In addition, the histological findings caused by ionizing radiation in the early period was investigated. The levels of MDA, GSH, SOD, CAT, GSH-Px and selenium were estimated in … …American Journal of Immunology, Vol. 1, Issue 3 · 30 Sep 2005 · 6,540 accessesView PDFCite
Research ArticleOpen accessIn the abstractReview of Pasteurella Multocida Infections over a Twelve-Year Period in a Tertiary Care HospitalAthanasia Christidou, Sofia Maraki, Zoe Gitti, Yiannis TselentisThe aim of this study was to present the epidemiological, clinical and microbiological data, as well as the management and the outcome of 13 patients with documented Pasteurella multocida infections, diagnosed in the University hospital of Crete, Greece, between 1993 and 2004. Most patients (62%) were >70 years of age. Respiratory tract infections were most commonly encountered (61.5%), followed by … …American Journal of Infectious Diseases, Vol. 1, Issue 2 · 30 Jun 2005 · 6,996 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Transcript Labeling Techniques and Development of a Membrane-based Parallel Gene Expression AssayMark A. Fisher, Bonnie B. Plikaytis, Thomas M. ShinnickAn inexpensive alternative to micro arrays was developed to examine the expression of small sets of genes in parallel and used to compare direct and indirect transcript labeling methods. Psoralen-biotin direct labeling was ~10-fold less sensitive than reverse transcriptase-biotin-dUTP labeling, but the enzymatic method generated higher levels of background noise in miniarray hybridizations. The reproducibility of hybridization intensities was the … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 6,868 accessesView PDFCite
Research ArticleOpen accessIn the abstractDecline of Betula ermanii with Special Reference to Ozone Concentration at Mt. Mae-Shirane, Oku-Nikko, JapanY. W. Feng, N. Ohta, H. ShimizuDuring June to October 2000 and 2001 we measured the height, Diameter at Breast Height (DBH) and stand density of Betula ermanii trees at Mt. Mae-Shirane, Japan and the ozone concentration there to explore the relationship between ozone concentration and the decline of B. ermanii trees on the mountain. Height, DBH and stem volume were lower on the southeast-facing slope … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 7,055 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Air Quality in Kuwait Urban and Industrial AreasHamad B Matar, Talal Almutairi, Nayef Z.
