The research paper being summarized in this report is In vitro activities of synthetic host defense propeptides processed by neutrophil elastase against cystic fibrosis pathogens authored by Stephen Desgranges, Florie Le Prieult, Alan Daly’ Jeniffer Lydon, Marian Brennan, Dilip K. Rai, Anusha P. Subasinghage, Chandralal M. Hewage, Sally-Ann Cryan, Catherine Greene, Noel G. McElvaney, Timothy P. Symth and Marc Devocelle. This paper was published in the journal Antimicrobial agents and chemotherapy under the American society for microbiology in May 2011. The journal has an impact factor of 4.672, a respectable impact factor for any reputable journal. Publishing of the work was significant to shed light on light on activities of synthetic host defense propeptides firsthand and hinder other person/groups doing so first.
The Desgranges et al have undertaken a study where they have reported the in vitro activities of synthetic host defense propeptides against cystic pathogens namely Staphylococcus aureus and Pseudomonas aeruginosa­. This paper focuses on the effect of modifying the propeptide by reducing the net change on the antimicrobial and hemolytic activity.
The aim of this work by Desgranges et al was to utilize the abnormal amounts of neutrophil elastase present in cystic fibrosis to process several synthetic prodrugs against common pathogens in cystic fibrosis, P. aeruginosa, and S. aureus. Peptides are present in many living systems and are utilized by the innate immune systems to combat invading pathogens. Therefore this study aims at constructing a propeptide that will be able to evade the host immune system and also be a substrate for the all abundant neutrophil elastase present in cystic fibrosis lung. ...Download file to see next pagesRead More

...for the couple owing to the different tests and procedures that a person has to undergo. It has been highlighted that eighty percent of the people who opt for in vitro fertilization as a choice of infertility treatment suffer from psychological problems which include depression and anxiety. It has been seen that stress and anxiousness is encountered both by the males and the females but the levels are higher in females. This is owing to their requirement to be more active participants in the procedure. If in vitro fertilization produces a positive outcome and the period of pregnancy is completed, the anxiety and depression subside. But if positive results are not achieved, the rates of...

In Vitro Fertilization

...? In Vitro Fertilization In vitro fertilization (IVF) first performed by two doctors, Patrick Steptoe and Robert Edwards, isa scientifically advanced procedure that provides an effectual solution for those couples who are suffering from infertility caused by any reason. Since the successful attempt in 1978, many couples in various parts all over the world have opted for this procedure and have enjoyed rewarding outcomes. In this simple procedure the egg is removed from the woman after ovulation and is then fertilized in the laboratory with a sperm under strict observation. After the formation of embryo, it is implanted in the woman’s uterus through a quick 20 minute procedure. The success rates of IVF are...

Host family

...Host families play a very important role for those individuals who happen to be on exchange and these often help in the adjustment of foreign exchange students to the life in a new environment. While this is the case, it is also important to note that host families often make a lasting impression on a foreign student that is visiting a certain country. I was privileged to have gone on exchange to the United States when I was younger and this period in my life has had a lasting impression. The impression that I got from visiting the United States and being in a new environment is one that was completely different from what I had expected. This was mainly due to the fact that most of the interactions that...

In-vitro Fertilization

...and would-be parents having difficulties conceiving. On that day, Louise Joy Brown, the world's first successful "test-tube" baby was born to British parents in Great Britain. It was considered an astounding feat for medicine, but it also led to sober reflection on the possible implications and abuse of the new technology. In vitro fertilization is a technique wherein the egg cells are fertilized by sperm outside the mother' womb. The zygote (or the fertilized egg) is then transferred back to the uterus, and the woman is guided through what is hoped to be a nomal pregnancy resulting in successful childbirth. Indeed, the question of in-vitro fertilization has given rise to a wide range of ethical...

I am lost within my own rhythm of chores. A sensitized journey along the streets to the unique shelter that I call my home is undergone and a homeostasis is reached for the day, until the day begins again and I start from the same point. I was supposed to know you by name, but I shall call you 'My synthetic journey'. This is a strange place I must visit, everyday between the sheets of happy colored mazes that make the lusts of my vision quite happy. I crawl with my mind to the sunny garden at the back of my house just from where all the streets begin all...

...EQUITY-LINKED a) The formulae are as follows: Re ment: Prove that the minimum return on initial investment F is equal to zero, and is less than the intermediate return, which in turn is less than the maximum return on initial investment of F (nominal rate) Per formula A, payoff (Index value at maturity) is equal to the initial investment, say, $1,000,000 if the return on the index exposure to the market is zero: $1,000,000 (1 + 0) = $1,000,000. If initial investment gains in the equity index options market by an amount less than the performance cap, then it gets back the $1,000,000 plus a specific return. E.g.: $1,000,000 (1 + .20) = $1,200,000. Finally if the options investment earns more than the cap of, say, 300... a) The formulae are as ...

Analytical and synthetic cubism

...What limitations/advantages do you see in analytical and synthetic cubism (painting)? Cubism invention via its key initiators Braque and Picasso had immense influence especially in the then existing art (Gardner & Kleiner 697). This encompassed cubism’s innovative ability to represent the world using multiplicity of images, besides the old single fixed viewpoint. The artist from then could easily and adequately represent his accumulative idea via two-dimensional perspective besides the traditional three-dimensional depiction (Gardner & Kleiner 400). This ensured effective coverage of the image’s informative aspects to the viewer by incorporating extra expansive structures; meant to add more explanation....

In-vitro Fertilization

...In-Vitro Fertilization In the United States, approximately 6.1 million people, which are almost 10% women and men of reproductive age, are affected by infertility. This is a condition where the couple lacks the capacity to conceive after a year of sexual intercourse without the use of protection or birth control methods. It is normally caused by one cause or the other between the two partners or a set of factors that prevent the pregnancy from occurring. Infertility diagnosis means that pregnancy is a challenge but not impossibility. Due to this challenge, numerous fertility treatments have been devised to help solve the problem. Modern technologies have come up that help women conceive. These are known as the Assisted...
