Research ArticleOpen accessIn the abstractSynthesis and Characterization of Silver/Clay Nanocomposites by Chemical Reduction MethodMansor Bin Ahmad, Kamyar Shameli, Majid Darroudi et al.Problem statement: Silver Nanoparticles (Ag-NPs) have been synthesized by using chemical reduction method into the interlayer space of a Montmorillonite (MMT) as a solid support which is used to antibacterial application and polymer nanocomposites for fabrication of medical devices. Approach: AgNO3 and NaBH4 were used as a silver precursor and reducing agent, respectively. The properties of Ag/MMT nanocomposites were studied … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 8,169 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn vitro Growth and Inhibition Studies of Monosodium Urate Monohydrate Crystals by Different Herbal ExtractsBharat B. Parekh, Sonal R. Vasant, Kashmira P. Tank et al.Problem statement: A large number of people in the world have been suffering from gout for centuries. Gout is the term given to a metabolic condition in which the signs and symptoms results from the deposition of crystals of Monosodium Urate Monohydrate (MSUM) in various connective tissues. Approach: It was quite difficult to grow good quality large MSUM crystals because … …American Journal of Infectious Diseases, Vol. 5, Issue 3 · 30 Sep 2009 · 10,210 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Antiangiogenic Effect of the Leaves of Justicia gendarussa (Burm. f ) (Acanthaceae) by Chrio Allontoic Membrane MethodK. Periyanayagam, B. Umamaheswari, L. Suseela et al.Problem statement: Angiogenesis involves the formation of new blood vessels from pre-existing blood vessels plays a crucial role in pathological processes such as diabetic retinopathy, arthritis and in the growth of solid tumors. Numerous reports had pointed out to the crucial role of neovascularization in the malignancy of tumors and other angiogenesis dependant diseases. Antiangiogenic therapy which targets activated endothelial … …American Journal of Infectious Diseases, Vol. 5, Issue 3 · 30 Sep 2009 · 9,152 accessesView PDFCite
