Research ArticleOpen accessIn the abstractThe Role of Nf-Kappa and HDCA and Implication of Oxidative Stress in Airway Inflammation of Chronic Obstructive Pulmonary DiseaseGhada A. Abdallah, Nevine M. Abd-Elfattah, Hala M. Ghanem et al.Oxidative stress has been implicated in the pathogenesis of Chronic Obstructive Pulmonary Disease (COPD), due to its effect on proinflammatory gene transcription. Oxidants/antioxidants imbalance is responsible for disease development. The study was designed to assess oxidative stress and inflammation in COPD patients. The level of TNF-α and IL-8 in sputum and BAL were compared. NF-κB and HDAC were measured in … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 4 · 4 Dec 2014 · 6,836 accessesView PDFCite
EditorialOpen accessIn the abstractNanotechnology: Engineering Materials for a Better 21st CenturyMeng Qiao, Xiyun Liu, Lei ZhangToday, we are living in the midst of a technological revolution, where nanotechnology is demonstrating a greater commitment to make people’s everyday lives better. The aim of nanotechnology is to create new materials with desired properties by engineering their nanoscale structures and components. One of the most important impacts of nanotechnology is in medical diagnosis and treatment. Cardiovascular diseases such … …Current Research in Nanotechnology, Vol. 5, Issue 1 · 26 Nov 2014 · 8,737 accessesView PDFCite
Research ArticleOpen accessIn the abstractPOSTERIOR CEREBROVASCULAR ACCIDENTS AFTER PERCUTANEOUS CORONARY INTERVENTIONCarlo Cosimo Quattrocchi, Andrea Maria Alexandre, Laura Scarciolla et al.Percutaneous Coronary Interventional procedures (PCIs) are recognised as gold standard treatment for high risks patients with diffuse coronary atherosclerosis. Neurologic complications are one of the most dreaded procedural outcomes, stroke after PCI affects mainly elderly and high-risk patients (age more than 80 years and use of intra-aortic balloon pump), with longer times of the procedure and angiographic complications, such as … …Current Research in Medicine, Vol. 5, Issue 1 · 14 Apr 2014 · 7,274 accessesView PDFCite
Research ArticleOpen accessIn the abstractISOLATION AND DETECTION OF HELICOBACTER PYLORI FROM PATIENTS SUFFERING FROM PEPTIC ULCER USING BIOCHEMICAL TESTS AND MOLECULAR TECHNIQUESRuba S. Abu-Sbeih, Azmi D. Hawari, Dhia S. Hassawi, Hala I. Al-DaghistaniHelicobacter pylori is the causative agent of most cases of gastritis. There is no established gold standard for the diagnosis of H. pylori infection. A reliable diagnosis is crucial to confirm that eradication therapy has been successful. Eighty gastric biopsy and blood samples were obtained from fasting Jordanian patients with Esophago-Gastro-Doudenoscopy (EGD). Several diagnosis tests for H. pylori infections were … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 1 · 28 Mar 2014 · 8,183 accessesView PDFCite
Research ArticleOpen accessIn the abstractMEDICAL IMAGE SEGMENTATION FOR ANATOMICAL KNOWLEDGE EXTRACTIONMs Maya Eapen, Reeba KorahComputed Tomography-Angiography (CTA) images of the abdomen, followed by precise segmentation and subsequent computation of shape based features of liver play an important role in hepatic surgery, patient/donor diagnosis during liver transplantation and at various treatment stages. Nevertheless, the issues like intensity similarity and Partial Volume Effect (PVE) between the neighboring organs; left the task of liver segmentation critical. The … …Journal of Computer Science, Vol. 10, Issue 7 · 22 Feb 2014 · 6,460 accessesView PDFCite
Research ArticleOpen accessIn the abstractCELL DETACHMENT BY PROLYL-SPECIFIC ENDOPEPTIDASE FROM WOLFIPORIA COCOSNicole Mika, Katharina Cierpka, Michaela C. Lange et al.As requirements for Advanced Therapy Medicinal Product (ATMP) production differ from other production processes (e.g., therapeutic protein production), cell detachment is often a crucial step for the process success. In most cases, cell detachment is done enzymatically. Although many peptidases are established in cell culture in R&D, e.g., Trypsin as gold standard, many of them seem to be unsuitable in … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 1 · 8 Feb 2014 · 8,157 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of enzyme Immunoassay with Immunofluorescence Assay for the Diagnosis of Mycoplasma pneumoniae Respiratory Tract Infections in ChildrenOsama Mohammed Saed Abdul-WahabMycoplasma pneumoniae is a frequent cause of acute respiratory infections in both children and adults. Currently, diagnosis of M. pneumoniae infection will based principally on serology and the detection of IgM can provide an early and sensitive diagnosis in children. A variety of commercial immunodiagnostic assays, such as Indirect Enzyme-Linked Immunosorbent (ELISA) assay and Indirect Immunofluorescence (IFA), are now available … …American Journal of Immunology, Vol. 9, Issue 2 · 21 Jun 2013 · 7,412 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetection of Cancer Biomarkers with NanotechnologyLei Zhang, Dan Lv, Weijun Su et al.Early detection of cancer biomarkers with high precision is critically important for cancer therapy. A variety of sensors based on different nanostructured materials have attracted intensive research interest due to their potential for highly sensitive and selective detection of cancer biomarkers. This review covers the use of a variety of nanostructured materials, including carbon nanotubes, silicon nanowires, gold nanoparticles and … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 1 · 18 Mar 2013 · 8,280 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmissivity of Triangular Surfaces Determined by Differential Method: From Homogenization to Validity Limit of Geometrical OpticsTaoufik Ghabara, Faouzi Ghmari, M. S. SifaouiGeometric optics approximation for emissivity from triangular surfaces was compared with exact scattering predictions from electromagnetic theory. Rigorous electromagnetic scattering theory was numerically formulated based on the differential method. We have used a numerical simulation of the emissivity of gold and tungsten for a wavelength equal 0.55 micron to explore the validity of the geometric optics. Surface parameter domains for … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,142 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Serological Gastric Biopsy: A Non-endoscopical/Histopathologic Diagnostic Approach in Management of the Dyspeptic PatientsR. A.K. Mahmoud, H. H. Morcos, A. A. Hegazi et al.Objective: To asses the sensitivity, specificity and the predictive value of a 'gastropanel' blood test, including serum pepsinogen I (S-PGI) and amidated gastrin-17 (S-G-17) in the diagnosis of atrophic gastritis most probably due to helicobacter pylori (Hp) and to compare the results of serology with the endoscopic/histopathologic findings as a gold standard diagnostic tool. This study comprised 86 dyspeptic outpatients … …American Journal of Immunology, Vol. 2, Issue 4 · 31 Dec 2006 · 7,131 accessesView PDFCite
