Acute Coronary Syndrome Acute coronary syndrome is a term used for any condition brought on by sudden‚ reduced blood flow to the heart. Acute coronary syndrome symptoms may include the type of chest pressure that you feel during a heart attack‚ or pressure in your chest while you’re at rest or doing light physical activity. Acute coronary syndrome is treatable if diagnosed quickly. Acute coronary syndrome treatments vary‚ depending on your signs‚ symptoms and overall health condition. Acute coronary

Antiplatelet agents‚ including aspirin‚ clopidogrel‚ dipyridamole and ticlopidine‚ work by inhibiting the production of thromboxane. Aspirin is highly recommended for preventing

The introduction of genes‚ white blood cells‚ blood groups‚ insulin‚ rubber gloves‚ aspirin‚ and vitamins and the discoveries of Pasteur‚ Charcot‚ Halsted‚ Zirm‚ Lister‚ and Koch were the starting point of an international fight against disease. A remarkable breakthrough in medicine occurred in the late 1800s through the work of Louis

Kawasaki disease is a rare condition that causes swelling and inflammation of the walls of the blood vessels (vasculitis). It also affect the mucous membranes‚ lymph nodes‚ skin‚ and the heart. It is important to treat Kawasaki disease as soon as possible to help prevent lasting damage. CAUSES The cause is not known. RISK FACTORS • Being under five years old. • Being of Asian descent. • Being a boy. SIGNS AND SYMPTOMS Symptoms for Kawasaki disease occur in phases. The first phase includes

Moreover‚ Iodine and aspirin acted different than what I expected. Iodine is a nonpolar substance but not dissolved in hexane. On the other hand‚ I noticed that aspirin is a nonpolar substance but it did not dissolved in water. Surprisingly‚ I found that some among above substances glycerol and motor oil which are nonpolar compound are soluble

In addition‚ we skipped the qualitative test of our purity for SA and Aspirin (ASA). The first part of this experiment is the preparation of ASA from SA were‚ we prepared our aspirin from the collected salicylic acid. A screw-capped vial was weighed empty to 29.7416 grams and filled with SA. The mass recorded of SA was 1.3995 grams of SA and it was weighed and transferred to

Lab #3: Stoichiometry of a Precipitation Reaction October 14‚ 2014 Abstract: The purpose of the lab‚ Stoichiometry of a Precipitation Reaction‚ is to be able to calculate the amount of a second reactant we need to react with the reactant one. You must calculate the amount of the second reactant using stoichiometry to figure out what amount is needed. After the amount is calculated‚ you then can add it to the first reactant and it will give you a full reaction. To figure out what you

As a result‚ the TLC analysis of Biogesic® yields the following Rf values where the given distance from origin to solvent front measures 59 mm: 1.) acetaminophen has a Rf value of 0.48; 2.) aspirin has a Rf value of 0.64; 3.) caffeine has a Rf value of 0.22; 4.) Biogesic® sample has a Rf value of 0.48 ; 5.) ibuprofen has a Rf value of 0.73; and 6.) mefenamic Acid has a Rf value of 0.76. Thus‚ the study shows that by having equal Rf values of
