...Personalized Medicine Kenneth Weddle Strayer University Science 115 Professor Meri Stanec May 21, 2012 Personalized Medicine Personalized medicine refers to the medical model that entails the customization of healthcare. Under personalized medicine, all the decisions and practices relating to an individual patient are advanced using genetic or any other vital pieces of information. The emergence of personalized medicine has helped in the reduction of costs, time, and the rate of failure of pharmaceutical clinical trials, has eliminated trial and error inefficiencies in the diagnosis of diseases, and has aided in the prescription of effective drugs and averted those that pose dangerous side effects to patients. This essay explicates the manner in which genetic technology may contribute to personalized medicine, examples of the benefits of personalized medicine, and drawbacks of personalized medicine. Modern genetic technology has played an instrumental role in leading to personalized medicine. It has led to in depth understanding of the impacts of genetics in a given disease. The understanding of the impacts of the disease has helped in the development of personalized medicine, as practitioners are able to identify the correct prescription for different diseases. Modern genetic technology has also led to personalized medicine by helping practitioners understand the significance of genes in the normal development...

...used in scientific research, including genomic and proteomic research, biotechnology, and pharmaceutical development. As one might expect, Sigma-Aldrich has a unique customer base. Their customers include life science companies, university, government institutions, hospitals, and industrial manufacturers. Currently, the Company operates in 40 countries and has approximately 9,000 employees. Sigma-Aldrich is organized into four business units. They are Essentials, SAFC, Bio Tech, and Specialties. In terms of percentage breakdown, specialties is their biggest unit accounting for approximately 37% of sales. With more than 1.3 million customers, Sigma-Aldrich has a unique customer base. The following graph shows their customer breakdown in terms of percentages. Sigma Aldrich is a great company and has done really well in the past, but we expect this this pattern to change. We are expecting sigma to see their revenues threatened by austerity in areas such as Europe and Asia. This is because of poor economical conditions and tough competition. Our research has also shown decreasing asset turnover and days sales outstanding. Because of this, we think, sigma will be forced to give favorable terms to its customers showing a definite overall weakness in the company. We have also noticed their inefficient use of leverage. Considering that most of Sigma’s growth comes from acquisitions, we believe, this is the best time to take advantage of low interest rates. As seen in the past, strong...

...gastrointestinal mucosa. The aim of this work was to investigate the effect of the fermentation pH and temperature on the surface properties and adhesion ability to Caco-2 cells of the probiotic strain Lactobacillus rhamnosus GG. Results: The cells were grown at pH 5, 5.5, 6 (temperature 37°C) and at pH 6.5 (temperature 25°C, 30°C and 37°C), and their surfaces analysed by X-ray photoelectron spectrometry (XPS), Fourier transform infrared spectroscopy (FT-IR) and gel-based proteomics. The results indicated that for all the fermentation conditions, with the exception of pH 5, a higher nitrogen to carbon ratio and a lower phosphate content was observed at the surface of the bacteria, which resulted in a lower surface hydrophobicity and reduced adhesion levels to Caco-2 cells as compared to the control fermentation (pH 6.5, 37°C). A number of adhesive proteins, which have been suggested in previous published works to take part in the adhesion of bacteria to the human gastrointestinal tract, were identified by proteomic analysis, with no significant differences between samples however. Conclusions: The temperature and the pH of the fermentation influenced the surface composition, hydrophobicity and the levels of...

...The medical field has come a long way. In today’s era, we are learning more due to the technology that is available to us and making it possible for medicinal products to become personalized. In this paper I will be explaining how modern genetic technology may lead to personalized medicine; discussing the benefits of personalized medicine; and discussing the drawbacks and limitations of personalized medicine. Explanation of how modern genetic technology may lead to personalized medicine. In order to understand how modern genetic technology may lead to personalized medicine, we need to first understand what personalized medicine is. Personalized medicine is the ability to determine an individual’s unique molecular characteristics and to use those genetic distinctions to diagnose more finely individual’s disease, select treatments that increase the chances of a successful outcome and reduce possible adverse reactions. Personalized medicine is also the ability to predict an individual’s susceptibility to diseases and thus to try to shape steps that may help to avoid or reduce the extent to which an individual will experience a disease. With that being said, the advancement in technology has made it possible for doctors and geneticists use a person’s DNA to find out what kinds of diseases are in their future; thus making it possible for them to make a stepping stone to prevent them. “The completion of the Human Genome Project in 2003 opened the door for better understanding of...

...sequencing of genomes, determination of the complete set of proteins encoded by an organism, and the functioning of genes and metabolic pathways in an organism. Thus genomics not only deals with the determination of the genetic information present in an organism, but also with the understanding the mechanism by which this information is used by the organism. A major branch of genomics is still concerned with sequencing the genomes of various organisms, but the knowledge of full genomes has created the possibility for the field of functional genomics, mainly concerned with patterns of gene expression during various conditions. Study of the full set of proteins in a cell type or tissue, and the changes during various conditions, is called proteomics. Genomics includes: ➢ Functional genomics --...

I also certify that I have never submitted the idea and product of this Project for academic or employment credits. XIAO Jiali, Jenny (0830300038) Date: ii Application of Bootstrap method in spectrometric data analysis XIAO Jiali, Jenny Science and Technology Division Abstract In this project the bootstrap methodology for spectrometric data is considered. The bootstrap can also compare two populations, without the normality condition and without the restriction to comparison of means. The most important new idea is that bootstrap resampling must mimic the separate samples design that produced the original data. Bootstrap in mean, bootstrap in median, and bootstrap in confidence interval are three kinds of effective way to handle mass spectrometric data. Then,we need to reduce dimension based on bootstrap method. It may allow the data to be more easily visualized. Afterwards, using results obtained by bootstrap, we use data mining method to predict a patient has ovarian cancer or not. Decision tree induction and neural network are usual way to...

...CASE STUDY: ROCHE’S NEW SCIENTIFIC METHOD QUESTION 1 For new drugs and size up toxicity risks earlier than ever. Projects needed to be managed in a totally different way. Roche can now churn out 1 million genomics experiments a day. Whereas research teams once spent years looking for a single good idea, they now must consider hundreds or even thousands of candidates daily. The data that is generated is overwhelming not only for the researchers, but also for Roche’s large infrastructure of computers. Despite the daunting task, the potential is too great for Roche to ignore. At a recent media briefing, Roche Group chairman and CEO Franz Humer declared, ‘‘look at this revolution of genetics, genomics, and proteomics. It’s becoming ever clearer that we will be able to identify early the predisposition of people to disease—and to monitor and treat them more effectively. We’ll develop markers for cancer. That will lead to better test kits and to new pharmaceuticals.’’ Thus, Roche’s U.S. pharmaceuticals headquarters is making adjustments to deal with having ‘too much data, too fast.’ Roche’s management has recognized that it needs to rethink the best ways to build teams, hire people, and create a culture where failure is all right, as long as it is fast. Roche has had to embrace an ¬-organizational revolution to accommodate the technological revolution. QUESTION 2 Roche mainly employs the Innovation strategy through the use of IT, driving change in organizational culture and...
