Keanna Barnes Abstract Current studies on oncolytic viruses have been underway to ultimately reduce the casualties cancer brings upon citizens globally. Lately‚ a series of clinical studies have shown clinical response when vaccines are combined with other forms of treatment in patients with all sorts of different cancers. Although scientists may be tempted to combine an oncolytic virus with an already existing radiation or chemotherapeutic‚ the long term goals have to be realistic and rational

Protists and Viruses A flagellum is a whiplike tail that helps organisms living in moist places to move The characteristics of protists is they are euckaryotic organisms‚ they are one or many-celled but do not have the complex organization found in plants and animals‚ and some make there own food and other can’t. Protists are plantlike‚ animallike and funguslike. A virus is a microscopic particles that make up either DNA or RNA core covered by a protein coat. Viruses are so small an electrn microscope

Designed to relentlessly replicate‚ computer viruses infect your programs and files‚ alter the way your computer operates or stop it from working altogether. It’s estimated that the Conficker virus infected more than 10 million computers in 2009. Tens of thousands of computer viruses now operate over the Internet‚ and new computer viruses are discovered every day. How does a computer virus find me? Even if you’re careful you can pick up computer viruses through normal Web activities like: Sharing

CHAPTER TWO Beneficial bacteria in the environment and their uses. In today’s world‚ the environment and its related issues are steadily gaining a lot of importance. Some bacteria are helpful and are used to obtain balance in the environment. It has been seen that helpful bacteria are useful in dissolving organic sludge from water‚ breaking down the growth of algae‚ reducing the various noxious odours such as hydrogen sulfide odours‚ reducing ammonia levels‚ promoting faster growth of fish in the

Cell Biology 1 – Prokaryotes & Viruses * Eukaryotes have a membrane whereas a prokaryote has no nuclear membranes. Both have a double stranded DNA. * The two main types of prokaryotes are bacteria and Archaea and eukarya are types of eukaryotes. * Archaea are more closely related to eukaryotes. * Prokaryotes have a membrane and nucleoid and most have a cell wall. * There are 3 main types of shapes of prokaryotes: * Bacillus – rod shapes * Spirilum – spiral shaped

Bacteria are among the oldest species in the world.They both incerease in number and comply with nature very quikly so‚they maintain their species.Therefore‚bacteria have been the most common type of species according to number.Hence‚bacteria had been classified in order to make analysis.easily.Bacteria can be classified into three main categories on the basis of their nurition:saprophytic‚parasitic and chemoautotrophic bacteria. The Saprophytic bacteria are the first type of bacteria

The concept of viruses being living or non-living has been greatly debated throughout the scientific community‚ essentially because of varying differences in scientist’s definitions of what constitutes life. Furthermore‚ scientists also disagree on the degree to which viruses fit into the living or non-living category. There are seven fundamental components which can be used to define life. The first being that living things must maintain homeostasis; the ability for it to control its internal temperature

a universal method of identifying bacteria allows for all scientists from any part of the world to identify the same species in an identical manner allowing for a precise of classification. Bacteria are distributed throughout the world in almost every conceivable habit. Bacteria are unicellular microorganisms‚ with variable shapes and nutritional needs. They lack a distinct nucleus and occur singly or in chains or clusters and form distinct colonies. Bacteria are classified on the basis of many

Bacteria are the most ancient life forms‚ most bacteria are so small that under a light microscope you can only see them as little dots. Some groups however grow to larger sizes and have spectacular shapes (1). Bacteria are present in most habitats on the planet‚ growing in soil‚ water‚ acidic hot springs‚ radioactive waste‚ and deep in the Earth’s crust‚ as well as in organic matter and the live bodies of plants and animals (2). Bacteria is mostly thought of as a pathogen‚ while it is true that

Questions: A. What are the advantages of using bleach as a disinfectant? The disadvantages? The advantages of using 70% alcohol? The disadvantages? 70% alcohol mixtures are capable of killing most bacteria within five minutes. However‚ the mixture is ineffective against spores and has limited effect on viruses. Additionally‚ the 70%
