Sejaphala M.D. Student No. 62399543 Unique Number: 770819 Introductory Microbiology MIB2601 Assignment 02 Due Date: 13 April 2018 QUESTION 1 1. Bacteria is stained using a primary stain called crystal violet and then fixed with a mordant which in most cases is iodine. While some bacteria have the ability to retain the primary stain, others discolor when exposed to the acetone and alcohol (95%). Hence, the Gram stain divides bacteria into two groups- these bacteria are grouped…

Electrical Properties AC Conductivity, Ac Resistivity, Dielectric loss, and Dielectric constant are electrical properties and measured as a function of frequency. AC Conductivity and Resistivity AC resistance (ρac) was recorded by LCR meter model 4275 in the frequency range 1MHz to 3GHz. AC conductivity was determined by using the value of Ac resistance. As we know, Ac Conductivity is reciprocal of Ac resistance can be calculated by the relation; ac =1/ρac (6) The variation of AC…

Muscle can be damaged whether it be from sports injuries or other accidents. When this muscle damage occurs, the body responds accordingly in order to regenerate this lost or injured muscle. There are three main steps that are necessary in order for this renewal to occur. These steps include inflammation, revascularization/satellite cell differentiation, and innervation. (Grounds, 2011) This paper will discuss the mechanisms the body uses in order to form regenerated skeletal muscle. Muscle…

Giardia intestinalis is a flagellated unicellular eukaryotic anaerobic organism that commonly causes diarrhoea disease throughout the world (Adam, 2001). Entamoeba histolytica is a non-flagellated unicellular eukaryotic (Petri, Singh, and and, 1999) with both aerobic and anaerobic capabilities (Montalvo, Reeves, and Warren, 1971), however it is generally considered to be anaerobic. Both are capable of motility, however the methods for this differ. G. intestinalis possesses flagella, which beat…

3. Nanomedicine in the treatment of cardiovascular disease 3.1 Intervention in cardiovascular disease with liposome Delivery of therapeutics to targeted tissues is possible through the design and construction of nanoscale particles while reduced toxicity as well as higher efficiency is obtainable [67,68]. Liposomes have huge skillfulness with regard to physicochemical characteristics, permitting acclimatization of the tiny particle to dovetail to the exact biological application [69]. Building…

increases the adsorption of Cl- ions at the values of negative potential which leads to the alloy dissolution [10]. The surface morphologies of Al, Alloy 1 and Alloy 2 after immersion in 2 M NaCl solution for 1 h were obtained by scanning electron microscopy (SEM) (Fig. 3). The morphology of Alloy 2 (Fig. 3C) in 2 M NaCl solution have large pits, which probably is due to the presence of larger amount of Pb film at the metal/oxide interface meanwhile Alloy 1 exhibited fairly smooth surface with…

Evaluation of Eugenia caryophyllata (clove oil) on vascular development of chick embryo Abstract: Eugenia caryophyllata is used in cooking, food processing, pharmacy; perfumery and cosmetics. In traditional medicine, the clove oil (eugenol) has been used in the dental care and in relieves respiratory disorder symptoms. The objective of this study was to investigate the effects of single dose clove oil on mortality rate, angiogenesis and vasculogenesis of chick embryos during early stages of…

Inflammation is a defense mechanism where the body’s white blood cells fight off bacteria, viruses, and damaged cells(Feeling the Heat- the Link between Inflammation and Cancer, 2013) . When pathogenic cells enter the body, the white blood cells surround that invasion site immediately(Feeling the Heat- the Link between Inflammation and Cancer, 2013) . The white blood cells then release a specific toxic chemical that denatures the pathogen enough to kill it(Feeling the Heat- the Link between…

Introduction: Herpes Labialis, also known as the cold sore, is characterized by painful clusters of clear blisters on or around the mouth, and is often accompanied with fever. The disease is usually caused by the virus HSV-1, or herpes simplex type 1, but can also be caused by HSV-2. In a previous study, it was found that 67.6% of Americans possessed antibodies for HSV-1, establishing HSV-1 as an exceptionally prevalent virus even in developed countries 9. The virus is spread through skin to…

C. APPROACH: C.1. Experimental rigor: We will apply our established in vitro and in vivo analyses to the studies proposed in both aims (31, 41, 42). Our preliminary data demonstrated the vigorous infection in both Heterozygotes (Foxn1nu/+) and homozygotes (Foxn1nu/nu) NU/J mice at mucosal sites. To minimize the possible variations in the animals, we will use siblings of these two inbred mouse strains. For the experiments proposed in both specific aims, we will use fifteen animals in each group…
