Another avenue of screening employs developing microscopic patterning technology called DNA microarray technologies in order to view certain characteristics of an individual's genetic makeup and health scenario. As Rushmore & Kong (2002) report, "advances in DNA microarray technologies and mammalian genome sequencing will soon allow quantitative assessment of expression profiles of all genes in the selected tissues." (Rushmore & Kong, 481)
This is particularly important because it represents opportunities in an area where most pharmacogenomics professionals contend the field must be expanded. At present, the largest focus in terms of application has been identifying single polymorphous cells for evaluation with respect to certain drug response likelihoods and tendencies. Naturally, the human genome is an incredibly complex chemical equation rendered by a set of permutations that is, for all intents and purposes, infinite. Therefore, the degree to which pharmacogenomics actually succeeds at improving treatment outcomes will hinge upon the ability of researchers to draw connections between a variance of permutations and certain drug responses. Accordingly, Evans & Relling1 (2004) denote that the field is at this juncture reaching an inflection point where a growth of ambition is necessary to achieve the safety and health outcomes intended. Their article denotes that "many of the genes examined in early studies were linked to highly penetrant, single-gene traits, but future advances hinge on the more difficult challenge of elucidating multi-gene determinants of drug response." (Evans & Relling1, 464)
The achievement of such outcomes depends on a continuation of the work that helped to make the Human Genome Project a success and which have contributed to the myriad avenues of innovation and exploration fueled thereby. Most particularly, the collaboration which saw commercial, scientific and medical fields coalescing to the single goal of making Western drug-based treatment programs exponentially more effective and safer must continue to be enjoyed. The federal government in the United States will also play a significant role on how well this is accomplished. As the online article by Bates et al. (2005) would indicate, "regulatory policies implemented by the FDA may directly impact the availability and accessibility of data by creating incentives or disincentives for example to share data or to collect certain types of...
Health Sciences Information Resources Ernst & Young (2001) describe the global health sciences marketplace as "a web created by pharmaceutical companies, biotech firms, eHealth companies, hospitals, physicians and other practitioners and medical device manufacturers" to name a few (p.1). This web or library of information is the wave of the future. Health sciences information libraries of the future will not just serve as global resources of health care information, but
Drug Therapy Advanced pharmacology Drug therapy: Individualized drug therapies Patient responses to drug therapy can vary widely between individuals. For example, not all patients find their pain alleviated by the same doses of analgesics; some patients can become suicidal when taking antidepressants rather than find their symptoms eased. It is because of the varied response of individuals, based upon their physical chemistry (as well as their social and psychological needs) that individualized drug
Genetics and Pharmacology Drug metabolism in humans is an essential topic to understand if one is to go into the pharmaceutical industry. When an individual ingests antibiotics their body is already prepared with the proper enzymes and molecular processes that allow for the breakdown and the uptake of these drugs. Xenobiotics encompass any substance that is foreign to the body; antibiotics fall into this category (Katzung, Masters, & Trevor, 2012). These
By monitoring patients in that process, the pharmacist has the opportunity to identify mistakes and other difficulties that could result in errors in drug administration. In a more general sense, pharmacists represent a valuable source of medical information for patients that could help prevent or identify problems before they manifest themselves in presentations that, in the most serious cases, result in unnecessary emergencies and hospitalizations. Technology and Communications: The evolution
Nutrigenomics is an important field of study. It finds in roots in modern times, because of the direct relation to advances in science and technology. Nutrigenomics also straddles the nature vs. nurture divide. The publication of the relatively preliminary results of the Human Genome has given greater impetus to the idea of Nutrigenomics. One might assuredly say that the publication of the Human Genome is preliminary because the current versions
