Medication and Treatment for COPD Inhaled Therapies NICE COPD guidelines have made specific recommendations regarding the use of inhaled long-acting bronchodilators and inhaled steroids separately and in combination‚ but newer studies have assessed these drugs singly and in combination over longer periods of time. Bronchodilators (relievers) Short-acting beta2 agonists (SABA) Beta2 agonists act directly on bronchial smooth muscle to cause bronchodilation. They are the most widely used bronchodilators

Abstract: Need for the study: Oral precancerous lesions are one of the most prevalent lesions worldwide today. Leukoplakia is the commonest premalignant lesion ‚ which if neglected can be fatal. Several therapeutic agents have been tried to intervene. Of which‚ Lycopene has been tried‚ tested and accepted as a conventional form of treating leukoplakia. Curcumin‚ 1‚7-bis-(4-hydroxy-3-methoxyphenyl)-1‚6- heptadiene-3‚5-dione] is regarded as the most biologically active constituent of the spice turmeric

1 Introduction 1.1 DEFINING POLYMERS Polymers are materials of very high molecular weight that are found to have multifarious applications in our modern society. They usually consist of several structural units bound together by covalent bonds [1‚2]. For example‚ polyethylene is a long-chain polymer and is represented by ÀCH2 CH2 CH2 À or ½ÀCH2 CH2 Àn ð1:1:1Þ where the structural (or repeat) unit is ÀCH2ÀCH2À and n represents the chain length of the polymer. Polymers are

Introduction The atmosphere is considered as a great cover that guards the earth’s surface from the full solar radiations during daytime and prevents excessive losses of heat during nighttime. The atmosphere provides a sustaining livable temperature on the planet by maintaining the heat balance of the earth. However‚ humans disregard the atmosphere through activities that contribute in polluting the surrounding. In order to prevent and minimize the air pollution‚ it is essential to understand the
