The fuel reserves of the world are very less and are depleting at a fast rate. So in future for the smooth livelihood of mankind, there is a need to find some others alternative sources of energy. We can dream of using nuclear power as the energy source but is posses problems related to environment and human health. The best alternative which comes in mind is HYDROGEN. It can be burned as a fuel in industry and power plants and possibly also in homes and motor vehicles. Thus, we can define Hydrogen Economy as the use of hydrogen as an energy source. The 'hydrogen economy' is being promoted as the solution to the world's energy problems. We had found some effective sources for hydrogen generation but the main issue left is its storage. Some of the metal doped complex hydrides had proved as an effective means of hydrogen storage but still we have to find more effective and cheaper sources. Thus there is a scope of further research in this field to find alternatives for hydrogen storage.

The present book contains the simple, fast and precise stability indicating method for the extended release formulation of Diclofenac sodium using high pressure liquid chromatography (HPLC).It contains the fundamental concepts to the analytical chemistry along with the in depth knowledge of HPLC. The objective of this book was to provide the basic concepts of the analysis by HPLC to the pharmacy fraternity.

Asthma remains a disease with clearly unsatisfactory therapeutics. With the mounting evidence in support of asthma being an inflammatory illness, anti-inflammatory agents have now become prerequisite for the long term management of asthma. Agents such as 2-agonists, antihistaminics, anticholinergics and inhalation steroids only treat symptoms and do not affect a cure to the underlying inflammation. On the other hand adenosine receptor modulators, selective PDE4 inhibitors, leukotriene modifiers and lipoxygenase inhibitors represent other therapeutic interventions with more targeted control by acting on different parts of immune system and the inflammatory processes. A combination of both of these approaches has been found to improve asthma control with a reduced dose of steroid. Development of PAF antagonists, thromboxane inhibitors, IL-4 modulators, antioxidants and anti-IgE are some of the cutting edge therapies, which offer better hope for asthma treatment. With many representative agents of each of these potential therapeutic targets, undergoing clinical studies, successful development of novel therapeutic agents in this field are not remote.
