Amlodipine is a calcium channel blocker that acts on the cardiac muscle and its peripheral vessels. Acting on the myocardial cells‚ which are responsible for the conduction of the electric stimuli of the heart‚ Amlodipine causes a decrease of the myocardial contractility [1]. Amlodipine causes dilation of coronary and peripheral arteries which is an important treatment of hypertension‚ as well as increasing blood flow to the cardiac muscle which aids angina [2].

The nanoparticles were characterized using transmission electron microscopy (TEM)‚ dynamic light scattering (DLS)‚ X-ray diffraction (XRD)‚ and ultraviolet–visible (UV–Vis) absorption spectroscopy; the antibacterial activity was assessed using the standard microdilution method‚ determining the minimum inhibitory concentration (MIC) according to the National Committee for Clinical Laboratory Standards. From the microscopies studies (TEM)

CHAPTER 1 Introduction and Its Background Introduction Infectious diseases are one of the main contributors to global mortality and morbidity. Infectious diseases are caused by pathogenic microorganisms‚ such as bacteria‚ viruses‚ parasites or fungi. These diseases can be spread‚ directly or indirectly‚ from one person to another. Vaccines‚ antibiotics‚ and many other advances have lessened the impact of infectious diseases. Unfortunately‚ this has not been true everywhere. It has not been true in

briefly explain why you identified each unknown as you did. 3 Unknown 1 was sodium and unknown 2 was potassium. Each element has it’s own color so all I did was match the element’s colors I had already tested with the unknown’s color. Part Two (Spectroscopy): 1 Create and complete a data table for Part Two of the lab. It should include the name of the element‚ the colors‚ and the wavelength values of the observed lines. 1 HydrogenHeliumSodiumNeonMercury1Pinkish-Purple (412nm)Blue (449nm)Yellow (580nm)Purple

The second element potassium knew it was because I acquired a blue color‚ in the experiment verified that each element corresponded to a different color.

Maria Anna Pabst of the Medical University of Graz in Austria used microscopy and spectroscopy to examine the tattoos. Since the tattooed neck circles contained a plant material instead of ash or soot‚ Pabst suggests that these tattoos were most likely part of a healing or strengthening practice. The tattooed circles are near what is known

Title: Studying SN1 and SN2 Reactions: Nucleophilic Substitutions at the saturated carbon Lab Partner: Jeszie Geronimo Objective and purpose: the purpose of this experiment is to convert a primary alcohol to an alkyl bromide using a Sn2 Reaction. Investigate some factors that influence the rate of Sn1 reactions. The second part of this lab will focus more on how unlike factors influence the rate of reactions in anSN1 reactions. The factors that we will be inspecting are the leaving groups‚ Cl-
