Abstract The primary goal for this laboratory experiment was to synthesize, purify, and identify p-nitroacetanilide using acetanilide as the starting material. To test for the purity and identification of our desired product, we gathered data from: Thin Layer Chromatography (TLC), Melting Point (MP) range, Infrared (IR) spectrum, Gas Chromatography Mass Spectroscopy (GC-MS), and Proton Nuclear Magnetic Resonance (1H NMR). TLC plate indicated the formation of our pure product due to the…

NANOCARRIERS AS PROMISING NOVEL SYSTEMS FOR CONTROLLED DELIVERY OF DICLOFENAC SODIUM [N.B: Authors' details blinded by Pro Journals for Review] ABSTRACT The formulation and evaluation of Diclofenac sodium from liposomes, niosomes and nanoemulsion are analyzed. The release profiles of Diclofenac sodium were almost similar in all the formulations. It is found that 85% of Diclofenac sodium diffused out from the colloidal systems within 8hrs and practically all the drug was released within…

Introduction: The world of antiseptics and disinfectants is ever changing. There are many different options out there and people have to decide what is the best option for them. For the experiment we performed in class, we had a variety of different options to use to see what the results would be from these. The range of items used were from and everyday household product of Lysol to Iodine which can be used in the operating room to prep the patient for the type of surgery they are having done.…

Daniel Huang Chapter 9 1. Mutations can be very negative in that it can cause cancer in somatic cells. However it is important to note that mutations will also lead to variability which is beneficial to us. Mutations in intergenic DNA affects regulations of protein products which is actually less detrimental than mutations in exons which code for the proteins. 2. Transition is the error that causes the base to change from a purine to purine or pyrimidine to pyrimidine. Transverses are base…

CHAPTER 1 INTRODUCTION 1.1 TUBERCULOSIS Tuberculosis (TB) is an infectious disease caused by the bacillus Mycobacterium tuberculosis. TB is a major global health problem and it ranks alongside Human Immunodeficiency Virus (HIV) as a leading cause of death worldwide. According to the estimates of WHO global tuberculosis report of 2015, there were 9.6 million people who developed TB and 1.5 million who died from the disease in 2014. 1.2 TRANSMISSION AND PATHOGENESIS OF TB TB infection occurs when…

I am instructed to use the AHP excel spreadsheet picking 4 criteria of my choice to evaluate the ideas. 2. IDEA GENERATION MIND MAP…

development. There are certain changes in gray and white matter densities, brain volume, as well as endocannabinoid concentrations. This creates aberrations in cognition and memory performance. Cannabinoid’s structures consist of a terpene joined to an alkyl-substituted resorcinol. The leading psychoactive component of cannabis is Delta-9-Tetrahydrocannabinol (THC). Cannabidiol (CBD) and cannabinol(CBN) are cannabinoids that make up cannabis (Perrine, 1996, p. 347-349). Gray and white…

The goal of this lab was to prepare methyl m-nitrobenzoate using electrophilic aromatic substitution. An example of electrophilic aromatic substitution is nitration where a hydrogen atom which is part of a aromatic ring is substituted by an electrophile. For benzene, aromaticity is a stabilizing feature. As such, instead of undergoing electrophilic additions, it undergoes electrophilic substitutions. The nitronium ion is the electrophile which gets attached to the electron rich aromatic…

Summary: Neurodegeneration is a collective term characterized by structural and functional loss of neurons which is a gradual and progressive process. Various neurodegenerative diseases like Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, etc. have been described by many biomarkers that are unusual in comparison to their baseline levels in the brain regions. Out of all the diseases, Alzheimer’s disease is the most prevailing disease in older patients with an average age greater…

Literature review Polymerisation of Cyclo pentene, Cyclo hexanes, Substituted Cyclo pentene and Cyclo hexanes using different catalyst Introduction:- Polymer is a word which is derived from Greek words “poly” which means many and “mer” which means parts. Polymers are substances which have large number of repeating structural units repeated in the same type of linkage. The chemistry that deals about polymers is called polymer chemistry and the reaction is called as polymerization. Polymer…
