Development of a Buccal tablets for Curcumin using Anacardium occidentale Gum

The objective of the present investigation was to develop uni-directional, bilayered, buccoadhesive tablets of curcumin using a natural buccoadhesive polymer cashew nut tree gum along with ethyl cellulose as an impermeable backing layer. A batch prepared with 20% polymer concentration, 0.1% penetration enhancer, 40 mg backing layer, compressed at 2 tons/cm2 for 10 sec was […]

Manganese Blocks Intracellular Trafficking of Shiga Toxin and Protects Against Shiga Toxicosis

Infections with Shiga toxin (STx)–producing bacteria cause more than a million deaths each year and have no definitive treatment. To exert its cytotoxic effect; STx invades cells through retrograde membrane trafficking; escaping the lysosomal degradative pathway. We found that the widely available metal manganese (Mn2+) blocked endosome-to-Golgi trafficking of STx and caused its degradation in […]

Hexavalent chromium removal from aqueous medium by activated carbon prepared from peanut shell: Adsorption kinetics; equilibrium and thermodynamic studies

Activated carbon was prepared from peanut shell by chemical activation with KOH. Unoxidized activated carbon was prepared in nitrogen atmosphere which was then heated in air at a desired temperature to get oxidized activated carbon. The prepared carbons were characterized for surface area and pore volume and utilized for the removal of Cr(VI) from aqueous […]

Cancer chemoprevention by nuts: evidence and promises

Chemoprevention is the use of chemical compounds to interfere with the early precancerous stages of carcinogenesis and thereby reverse tumor formation. Many chemopreventive agents; either natural or synthetic; have been identified. Some of the most promising compounds are found in vegetables and fruits. There are numerous mechanisms of action by which these components can intervene […]

Optimizing the removal of fluoride from water using new carbons obtained by modification of nut shell with a calcium solution from egg shell

Carbons loaded with specific chemical moieties were prepared from pecan nut shells employing a natural modifier agent obtained from egg shell; which is rich in calcium; for the selective adsorption of fluoride from water. A L4 orthogonal array of the Taguchi method was used to optimize the synthesis conditions for obtaining these selective carbons. The […]
