Headache Introduction “A Headache is defined as a pain in the head or upper neck. It is one of the most common locations of pain in the body and has many causes. Headaches have numerous causes‚ and in 2007 the International Headache Society agreed upon an updated classification system for headache.”(1) Because so many people suffer from headaches and because treatment sometimes is difficult‚ it is hoped that the new classification system will allow health care practitioners come

ABSTRACT The pesticides are one of the most potentially harmful chemicals liberated in the environment in an unplanned manner. Dichlorovos is widely used as a potent pesticide in many countries and has been shown to produce some adverse health effects. This study was designed to clarify whether dichlorovos an organophosphorus (OP) compound causes detectable adverse effects on rat testes. Dichlorovos was administered to rats orally at dose level of 20 mg/kg/body wt./day for 45 days. Sex organ weight

Organic Chemistry II Laboratory (ABCT357) Although studying fundamental theories of chemistry in the class is important to understand the concept of chemistry‚ carrying out experiments to corroborate the theories is also important. It is very important for students to get used to experiments in order to speed up their experiments. Expt.1. Acetylation of α-D-glucopyranose Add slowly 2.5 g (0.014 mol) of powdered D-glucose in small portions (roughly in 7-10 portions and 5 min for each addition)

1-propanol 2-propanol Functional isomers‚ on the other hand‚ have very different chemical properties because differences in the structures give rise to different functional groups. ex. CH3CH2OH CH3OCH3 ethanol dimethyl ether Stereoisomers are molecules which have the same basic arrangement of atoms in their molecules but differ in the way the atoms are arranged in space. There are three basic types of stereoisomers such as conformational isomers‚ geometric

Introduction: The purpose of this lab is to use staining techniques and biochemical testing to identify an unknown bacteria using Bergey’s manual. Bergey’s manual of Systematic Bacteriology is a dichotomous key primarily used to identify a bacterial species. Biochemical tests are used to differentiate different species of bacteria. These tests are effective in determining the characteristics of the microbe being tested. Such characteristics include citrate utilization‚ gelatin hydrolysis‚ nitrate

SBI4U-C 1 Lesson Introducing Biochemistry 1 Lesson 1 Biology SBI4U-C Introduction If you think about it‚ living things are made up of chemicals. The cells‚ tissues‚ organs‚ and organ systems that together make up a functioning organism are all the product of interacting chemicals. In order to understand how the organism functions‚ you must also recognize how these chemicals function. The study of the chemicals that are involved in living things is known as biochemistry
