Research ArticleOpen accessEvery word in the titleSulfa Allergy: Cross-Reactivity Versus Multiple Concurrent AllergiesMuhammad Tariq Shakoor, Samia Ayub, Zunaira AyubAs a medical resident we have always been taught that there is some sort of cross reactivity between sulfonamide antibiotics and nonantibiotic sulfonamides. Even the manufacturer’s package inserts contain a precautionary statement about possible Cross-reactivity. The most common approach to this problem is avoidance of all sulfa containing drugs. However, there are few data supporting this contraindication. Thus we may … …American Journal of Infectious Diseases, Vol. 9, Issue 4 · 2 Dec 2013 · 9,629 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCross Reactivity between Dromedary Whey Proteins and IgG Anti Bovine α-Lactalbumin and Anti Bovine β-LactoglobulinN. Youcef, D. Saidi, F. Mezemaze et al.Problem statement: Our aim was to enhance the data on antigenic properties of dromedary whey proteins. Approach: The identification of the whey proteins was carried by SDS-page and Reversed phase high performance liquid chromatography (RP-HPLC). The cross-reactivity of dromedary whey proteins with IgG anti bovine β-lactoglobulin and anti bovine α-lactalbumin, obtained by immunisation of Balb/c mice, was carried out by … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,429 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleC-Terminal Region of Dengue Virus Nonstructural Protein 1 Is Involved in Endothelial Cell Cross-Reactivity via Molecular MimicryShu-Wen Wan, Chiou-Feng Lin, Mei-Chun Chen et al.Infection with dengue virus (DV) causes diseases ranging from self-limited dengue fever to life-threatening dengue hemorrhagic fever and dengue shock syndrome. Vascular leakage, thrombocytopenia and bleeding are the clinical manifestations associated with dengue hemorrhage. We previously showed that anti-DV nonstructural protein 1 (NS1) antibodies (Abs) cross-reacted with endothelial cells. The potential target proteins on endothelial cell surface recognized by anti-DV … …American Journal of Infectious Diseases, Vol. 4, Issue 1 · 31 Mar 2008 · 7,560 accessesView PDFCite
Research NotesOpen accessIn the keywordsFunctionalization Strategies for Antibodies: Lessons LearnedChristian Schmidt, Martin Geyer, Jörg Bohrisch et al.Precious little is known about useful functionalization strategies of antibodies that will not impair either reactivity or specificity of this valuable reagent. We used an experimental approach to demonstrate our own experience with published protocols. The conjugates obtained were then tested with regard to their performance against commercially available detection kits. Our results are then viewed in light of published … …American Journal of Immunology, Vol. 13, Issue 2 · 4 May 2017 · 7,592 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPOLLEN-FRUIT SYNDROMES: A CASE WITH BIRCH-APPLE-CARROT ASSOCIATIONJ. Minov, J. Karadzinska-Bislimovska, S. Stoleski et al.Subjects with sensitivities to certain pollen can experience oral or systemic allergic symptoms associated with ingestion of various fruits, vegetables and nuts. In this case report a birch-apple-carrot association in 23-year-old man suffering from pollinosis who experienced few episodes of oral allergy syndrome, generalized urticaria and bronchospasm immediately time after ingestion of fresh and cooked apple and carrot is presented. … …American Journal of Immunology, Vol. 10, Issue 2 · 10 May 2014 · 7,168 accessesView PDFCite
Research ArticleOpen accessIn the abstractPathological and Immunohistochemical Findings of Prostate Glands from Clinically Normal DogsFiras Mohammed Abed, Asseel Mohammed Rahawi, Hadil Basim Al-Sabaawy et al.To investigate the incidental histopathologic findings in clinically normal dogs and determine the immunohistochemical expression of several tissue-specific differentiation markers. The University of Mosul's animal research ethical committee authorized this study (UoM.Dent/A.DM.L.1/22). Seven samples were obtained from the veterinary hospital in cooperation with the College of Dentistry. Dogs with two detectable testicles were considered intact. Dogs with a history of … …American Journal of Animal and Veterinary Sciences, Vol. 18, Issue 4 · 13 Nov 2023 · 5,198 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Vitamin B17 Against Growth of Colitis Bearing Mice Induced Variations in Colon Structure, AFP, CEA and PCNA ImmunoreactivityGihan Hosny Abd Elsamie, Sabah Gaber El-Banna, Ehab Tousson et al.Colitis alludes to inflammation of the internal coating of the colon that accompanied clinically through abdominal pains, diarrhea, weight loss, nausea. Current study aimed to study the impact of vitamin B17 against growth of colitis bearing mice induced variations in colon structure, AFP, CEA and PCNA immune reactivity. Forty female Swiss albino mice separated into 4 groups (Control, vitamin B17, … …OnLine Journal of Biological Sciences, Vol. 21, Issue 3 · 23 Aug 2021 · 6,397 accessesView PDFCite
Research ArticleOpen accessIn the abstractComputer Aid Screening for Potential Antimalarial Choroquinone Compounds as Covid 19 Utilizing Computational Calculations and Molecular Docking StudyAsmaa Aboelnaga, Asmaa M. Fahim, Taghreed H. EL-SayedClick reaction of 4,7-dichloroquinoline (1) with thiosemicarbazide (2) to afford the corresponding 2-(7-chloroquinolin-4-yl)thiosemicarbazide (3) utilized ultrasonic irradiation which can cyclized easily with ethylacetoacetate to give the 3-(7-chloroquinolin-4-ylamino)-tetrahydro-6-methyl-2-thioxopyrimidin-4(1H)-one (4) via nucleophilic substitution reaction. The synthesized compounds was examined in vitro antimalarial activity with IC50 = 11.92, 25.37 μg/mL against chloroquinone drug. Furthermore, the theoretical investigation of most active compounds CQT and … …OnLine Journal of Biological Sciences, Vol. 20, Issue 4 · 30 Nov 2020 · 6,568 accessesView PDFCite
Research ArticleOpen accessIn the abstractELISA-Based Development of Functional Antibodies for the Efficient Detection of Mycotoxigenic Fusarium (F. oxysporum and F. circinatum) and Diplodia (D. pinea) SpeciesPhumzile Mkhize, Phetole MangenaFusarium contains the most toxigenic and important fungal pathogens, producing a wide range of mycotoxins that include the more toxic secondary metabolites called fumonisins. This study analyzed the presence of common exo- and mycelium-soluble antigens, purified proteins using reducing SDS-PAGE and the expression of antibodies against different fungal pathogens. The results showed the presence of common antigens between pathogens and … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 18 Nov 2020 · 6,601 accessesView PDFCite
Research ArticleOpen accessIn the abstractToxicology of Nanomaterials on ZebrafishJimmy De León, María del C. Cotto, Francisco MárquezIncreases in the use and the progressive manufacture of new Engineered Nanomaterials (ENMs) lead to inquire about their impact on the environment. Due to the small size, high reactivity inside organisms and the unusual physicochemical properties of the ENMs, the predictions of toxicity are very complex. The zebrafish (Danio rerio) has been granted as a practical alternative to study the … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 29 May 2019 · 7,784 accessesView PDFCite
