Double-J (DJ) stenting is the commonest procedure performed in urology. Patients with stent‚ develop stent infections and stent-related symptoms. Use of antibiotics in patients with DJ stent is rampant. No uniform data is there to prove advantage of antibiotic prophylaxis. Colonial way of life of microorganisms‚ complex microbial assemblages are responsible for formation of biofilm. Both gram positive and gram negative bacteria produces biofilm. Biofilm is an important virulence factor and is main

The Double Helix James Watson accounts all the events of his career that occurred during 1950 to 1953‚ which led to the discovery of structure of the DNA in his famous piece of science writing called “The Double Helix”. In his book‚ James Watson describes how he and Francis Crick discovered the structure of the deoxyribose nucleic acid (DNA) that leads to the major themes of this book‚ which is nature of scientific discovery. Watson describes his and Crick’s search for a simple explanation of DNA

PSY F370 Drugs and Behavior Fall 2013 November 9‚ 2013 Opioid Replacement Therapy Medications used for opiate addiction work as agonists‚ antagonists or utilize a combination of both actions. By definition‚ agonists cause a chemical action by binding to cell receptors and mimicking the action of naturally occurring substances such as neurochemicals. Antagonists also attach to cell receptor sites but instead of causing an action‚ they block the receptor from being stimulated by a target substance

experiment the objective was to perform a Diels-Alder reaction using cyclopentadiene and maleic anhydride to synthesize the product‚ cis-Norbornene-5‚6-endo-dicarboxylic anhydride. The Diels-Alder reaction is one of the most important reactions in organic chemistry and was first investigated by Otto Diels and Kurt Alder in Germany. It is a [4+2] concerted cycloaddition reaction which involves a diene and a dienophile. The Diel-Alder reaction are mainly used for creating new carbon-carbon bonds‚ mostly

A total shoulder replacement is a common orthopedic surgery that occurs in the United States. It may not be as common as the hip or knee replacement‚ but it still gets the job done at alleviating joint pain and getting a person back to doing their daily activities. Typically‚ a total shoulder replacement will consist of replacing the impaired parts of the shoulder joint with an artificial prosthesis. The two surgical options are to replace just the ball of the humerus or replace both the humeral

Heart valve replacements are more common than most people think. In the United States it is said that over 99‚000 heart valve surgeries are performed yearly. The majority of the valve replacement surgeries are to replace or repair the mitral or aortic valve‚ since the left side of the heart works harder than the right. There are several types of valve disease‚ the two most common are valvular stenosis and valvular insufficiency. Valvular stenosis occurs when the opening of the valve is smaller

Discussion The purpose of this lab is to display the influence of retronasal olfaction when it comes to flavor. Humans have two different types of olfaction. Olfaction is the detection of chemicals in the air. These chemicals which are meant to activate odor receptors‚ are called odorants. Humans have approximately 20 million olfactory receptors‚ which is only a fraction compared to bloodhounds who have 4 billion. The first type of olfaction is called orthonasal olfaction which is inhaling. Here
