solubilization can allow the drug to stay in the circulatory system for longer periods and‚ because of their larger size‚ they can amass in areas with leaky vasculature. Besides increasing solubility‚ another advantage of micellization is reduced risk of toxicity and enhanced permeability. An interesting feature of micelles is the fact that the location of the drug in the micelle depends on the degree of hydrophobicity of the drug. The more hydrophobic or poorly soluble a drug is‚ the closer to the interior

Rowley 1 Ignorance is Bliss Ever since the invention of automobiles‚ something can always be said about someone based on the type of car they drive. When someone drives a big gas guzzling SUV or truck‚ someone always says‚ “what a terrible person! Don’t they understand what they are doing to the environment?” Then someone drives by in a Toyota Prius and that same person says “Now that’s a smart person.

Sex organ weight analysis‚ fertility‚ biochemical‚ enzymatical and hormonal parameters were the criteria used to evaluate the toxicity of the dichlorovos in treated rats. Study shows significant decline in the weight of testes‚ epididymis‚ seminal vesicle‚ ventral prostate and reduction in sperm counts both in epididymis and testes in toxicated animals.

nuts will be extracted in a standard method as previously performed in many published works. Several solvents including water‚ acetone‚ ethanol and methanol will be used in our extraction procedure to determine the proper solvent with acceptable toxicity effect over cells and maximum-targeted extraction. The proper concentration and incubation time with the targeted extract will be optimized through a pilot study. 4-6 Apoptosis Assessment 4-6-1 Screenings

chemical synthesis are carried out in solution and organic solvents usually are the first choice. To satisfy this demand‚ 15 billion kilograms of organic are produced worldwide each year. [1] These solvents often bear considerable risk due to their toxicity‚ flammability or environmental hazards. Furthermore‚ they have to be separated from the products and recycled or disposed at the end of the process‚ increasing the overall production cost. Although they play a valuable role‚ organic solvents are
