New approaches directed to unraveling monoterpene metabolism and secretion and recent progress in transformation protocols have set the stage for the systematic genetic engineering of essential oil production. This article focuses on specific strategies to improve the quality and quantity of mint essential oils.

the fast depletion of petroleum crude oil reserves and the serious consideration of environmental issues make the implementation of sustainable energy sources a crucial issue worldwide. biofuel derived from vegetable oils is receiving a great attention as one of the most suitable and logical alternatives of fossil fuels. therefore, the production of petroleum-like fractions from nonedible oil e...

The use of cryo-techniques in macromolecular crystallography has increased enormously over the last eight years and has become a vital part of modern X-ray data-collection methods. This paper presents some reasons for the rise in popularity of cryo-techniques and a brief outline of the basic methods, followed by a detailed discussion of factors to be considered when trying to optimize both the ...

in research outputs both quality and quantity are of critical value and evaluation of both aspects is required for best evaluation. several studies have worked on single or two-dimensional methods that provide the assessment of quality, quantity or both simultaneously in different branches of sciences, but none of them have played a role in a particular area of medicine. this study has been con...
