This book highlighted the methods used for the syntheses of thiosemicarbazide and their metal complexes. Molecular modelling for all prepared compounds was investigated. Dissociation and formation constants were calculated for ligands and complexes respectively. In vitro and in vivo studies for thiosemicarbazides showed high potent antitumor activity. Finally, this book reported thiosemcarbazide derivatives as organic chelates (which are not pollutant for water media and may have biological importance) for the separation of about 100% of Hg2+, Mn2+ and Cd2+ ions.

This book is of significance for both tomato growers and researchers interested in studying diseases that infect tomatoes.As it sheds light on spotting bacterial disease of tomato in terms of its importance, the extent of its spread in Egypt, and the sensitivity of different tomato cultivars for infection with this disease. As well as studying the biochemical effects in tomato plants resulting from infection, and pathological and molecular diversity between different isolates of the pathogen. One of the most important parts contained in this book is how to control the disease by using...

The search for cancer cure from natural products have been practiced for over a century. For the last 25 years, El-Asmer and co-workers were pursuing the search for potential therapeutic agent or new drug models from snake venoms. This work was presented for partial fulfillment of M.D. in Biochemistry. A cytolytic, non-antigenic, 8 kDa, glycoprotein (Fraction VIb) was isolated from crude Naja nigricollis nigricollis spitting cobra venom. This protein is stable at different pH values and different temperatures up to 100 C, lethal to mice, with LD50 1.83 mg/kg. Small doses induced cytolytic...
