The physician orders the neuromuscular blocking agent metocurine iodide (metubine) to reduce trauma by relaxing skeletal muscles. Explain the process of muscle contraction and how a neuromuscular blocking agent‚ such as metubine‚ would interfere with muscle contraction. According to the Mayo Clinic website electroconvulsive treatment is the use of an electrical

Abstract A natural polyphenolic compound Quercetin was extracted from widely available and consumed plant Allium fistulosum which has shown promising chemo preventive and chemotherapeutic activities in cancer. In this study‚ quercetin is encapsulated and loaded onto PLGA (Poly lactic glycolic acid) microspheres using double emulsification methodology for improving its efficiency in cancer therapy. Quercetin is extracted and purified using chromatographic and nuclear magnetic resonance (NMR) techniques

Chem 106 Section 12 1. Introduction: This lab focused on showing the reaction that takes place between zinc and iodine using only deionized water instead of acetic acid (or vinegar) as we did in the previous lab by adding acetic acid to zinc iodide. The purpose of this lab was to see how water created the reaction and another compound or precipitate. Focus Question: Zn(OH)2 was the product when zinc and iodine were reacted without the presence of acetic acid in the water. Confidence Report:

identified that unknown sample C is potassium iodide. I identified that potassium ions were present as a lilac flame was produced during the flame test and it did not produce a precipitate in the sodium hydroxide test‚ which shows that potassium ions are present. The chemical equation for this reaction is: KI(aq) + NaOH(aq) KOH(s) + NaI(aq) I identified it to be an iodide as a yellow precipitate was produced during the silver nitrate test‚ indicating iodide ions are present. The chemical equation for
