tics Antibiotics Several scientists around the beginning of the 20th Century discovered substances that were toxic to bacteria yet not to the human cell. But it wasn’t until Sir Alexander Flemings own discovery in 1928 that everyone took notice. While washing his equipment‚ Sir Fleming noticed a bit of mold attacking a patch of bacteria. It’s frightening to consider how many more people would have died in the 20th Century if Sir Fleming did not have good eyes. Today‚ some complain that

Antibiotics research 1. Define the term antibiotics Antibiotics are a drug used to treat infections caused by bacteria and other microorganisms. Originally‚ an antibiotic was a substance produced by one microorganism that selectively inhibits the growth of another. Synthetic antibiotics‚ usually chemically related to natural antibiotics‚ have since been produced that accomplish comparable tasks 2. a) who was the first scientist to discover antibiotics Alexander Fleming (1928) b) Briefly

Linear Programming Notes VII Sensitivity Analysis 1 Introduction When you use a mathematical model to describe reality you must make approximations. The world is more complicated than the kinds of optimization problems that we are able to solve. Linearity assumptions usually are significant approximations. Another important approximation comes because you cannot be sure of the data that you put into the model. Your knowledge of the relevant technology may be imprecise‚ forcing you to approximate

Matthew Taylor PhD MSc Senior Consultant‚ York Health Economics Consortium‚ University of York G While economic models are a useful tool to aid decision-making in healthcare‚ there remain several types of uncertainty associated with this method of analysis.

Antibiotic resistance In recent years a challenge to the effective treatment of an ever-increasing range of infections caused by microbes is antimicrobial resistance (AMR). AMR results in reduced effectiveness of antibiotics‚ making the treatment of patients very difficult and sometimes impossible. The impact on especially susceptible patients is most evident‚ resulting in prolonged illness and increased mortality. The total problem caused by AMR on medical field in general and healthcare sector

Abstract The spread of antibiotic resistance is a universal threat to both humans and animals for treatment of microbial infections. The antibiotic resistance is generally not preventable but can still be controlled. Prolonged and repeated use of antibiotic leads to many pathogen becoming resistant to antibiotics. The resistance may be either intrinsic or acquired depending on the condition. Although classically attributed to chromosomal mutations‚ resistance is most commonly associated with

discoveries is antibiotics which have revolutionized today’s medicine. Perhaps my choice will match up with yours‚ or maybe it will be vastly different. The discovery of antibiotics has proved to be a boon a boon to human welfare but some also have the opinion that they are the necessary evils. We do have Alexander Flemming to thank for this discovery back in 1928[1]‚ when he forgot to clean up his workstation before going on holiday after which the golden age of antibiotics started. Antibiotics are the
