REFERENCE ID: 201002578 TITLE SCREENING PREGNANT WOMEN FOR PERIODONTITIS BY ANALYSING SALIVARY ALKALINE PHOSPHATASE AND LACTATE DEHYDROGENASE INTRODUCTION Periodontal disease can induce systemic inflammatory and immune responses and may be associated with an increased risk of systemic diseases such as cardiovascular disease and rheumatoid arthritis.1–3 Periodontal disease is common in pregnant women4 and increases the risk of adverse pregnancy outcomes including preterm birth‚ low birth weight

(Bridges‚ 1938). Endomitosis is the process of mitosis of chromosomes without undergoing nuclear or cellular division to increase cell volume. This results in a single nucleus having many copies of a single chromosome (Painter & Reindorp‚ 1940). In this experiment‚ Drosophila melanogaster is reared in specific conditions and its salivary gland extracted to study endomitosis. I hypothesize that I will see endomitosis in the salivary gland chromosome of third instar larval D. melanogaster. My prediction

Drosophila melanogaster is a fruit fly‚ about 3mm in length‚ and it is the insect that flies around spoiled fruit. A model organism has these traits: short life cycles and rapid development‚ small average size‚ big population‚ and fast reproduction (NCBI). Drosophila melanogaster meet all of the criteria for being a model organism. Also‚ fruit flies were used because they are very easy to handle and they require minimal resources to survive‚ as opposed to other organisms that might need more food

either be sex-linked or autosomal. If a gene appears mostly in one sex chances are the gene is sex-linked and if it appears frequently in both sexes it is most likely autosomal. Using Drosophila melanogaster‚ also known as the fruit fly‚ we will determine whether the gene is sex-linked or autosomal. Drosophila melanogasters have a relatively short life span and are an excellent organism for genetic studies because it has simple food requirements‚ occupies little space‚ is hardy‚ completes its life cycle

Genetics & Drosophila Melanogaster Lab Report Background: For two months‚ you will breed Drosphila melanogaster (fruit flies) and set up genetic crosses in order to determine the pattern of inheritance of certain mutant traits. The traits for which we will examine the pattern of inheritance are apterous (wingless)‚ vestigial (crippled wings) or white eyes. These are all mutant strains. The normal condition (winged and red eyes) is referred to as the wild type strain. Objective: The intial

in Fruit Flies INTRODUCTION The Drosophila melanogaster‚ more commonly known as the fruit fly‚ is a popular species used in genetic experiments. In fact‚ Thomas Hunt Morgan began using Drosophila in the early 1900’s to study genes and their relation to certain chromosomes(Biology 263). Scientists have located over 500 genes on the four chromosomes in the fly. There are many advantages in using Drosophila for these types of studies. Drosophila melanogaster can lay hundreds of eggs after just

How the Loss of Dysbindin‚ a Schizophrenia Susceptibility Gene‚ Affects Sleep Patterns in Drosophila Links between genes and mental disorders have been found throughout science. One mental malady being focused on today is schizophrenia. Schizophrenia is shown to have many sources or possible causes (Maier‚ 2008); however the primary and most studied cause is the link between schizophrenia and the dysibindin gene. Statement of Problem The problem being studied is whether dysbindin is the

Summarize The review focuses on how D. melanogaster can be utilized to answer questions about functions of genes involved in human diseases. Review various human disease genes w/ identified homologous in D. melanogaster the availability of genome sequences of human and model organisms has provided a good opportunity to investigate the conservation of genes responsible for heritable diseases in human such as Neurological disorders‚ developmental disorders‚ Familial Alzheimer disease‚ Fragile
