In this study, N, Scodoped titania photocatalyst was synthesized through an efficient and straight forward method using a single source, ammonium sulfate, as modification agent of titanium isopropoxide (TTIP) precursor. The catalyst was characterized by X-ray powder diffractometer (XRD), element Analysis of carbon, hydrogen, nitrogen (CHN), scanning electron microscopy (SEM), diffuse reflectanc...

Introduction: Erythrocytes are highly specialized and the most abundant cell type in vertebrates’ blood. Their main function is the transportation of oxygen to tissues of the body via hemoglobin. Methods: The study was aimed at evaluating erythrocyte morphology in Clarias gariepinus (Cg), Bufo bufo (Bb), and Agama agama (Aa) using different stains; Also, morphometric analysis of erythrocyte w...

About 10 years ago we discovered that bubbling nitric oxide (NO) gas into KrebsRinger bicarbonate solution containing isolated precontracted strips of bovine coronary artery caused a rapid and pronounced, but transient, relaxant response that was antagonized by oxidized hemoproteins, such as methemoglobin, and by methylene blue. NO activated soluble guanylate cyclase prepared from coronary arte...

OBJECTIVE To describe photosensitization after prenatal exposure to a toxic amount of methylene blue and to alert pediatricians that, in a review of the literature, photosensitization (which this dye is capable of) has not been reported as a complication of prenatal exposure. DESIGN AND PATIENTS A descriptive report of physical findings and significant laboratory tests in a very low birth wei...
