The mammalian natriuretic peptide system, consisting of at least three
ligands and three receptors, plays critical roles in health and disease. Exam-ination of genetically engineered animal models has suggested the signifi-cance of the natriuretic peptide system in cardiovascular, renal and skeletal
Biofuels such as bioethanol are becoming a viable alternative
to fossil fuels. Utilizing agricultural biomass for the production
of biofuel has drawn much interest in many science and
engineering disciplines. As one of the major crops, maize
offers promise in this regard. Compared to other crops with
biofuel potential, maize can provide both starch (seed) and
cellulosic (stover) material for bioethanol production.
Genetically modified foods and food products derived from genetically engineered
organisms are among a number of biotechnological developments intended
to improve shelf life, nutritional content, flavor, color, and texture, as well as
agronomic and processing characteristics. Although in popular parlance the term
genetically modified often is used interchangeably with genetically engineered,
in this report genetic modification refers to a range of methods used to alter the
genetic composition of a plant or animal, including traditional hybridization and
Search engines remain popular—and users are more satisfied than ever with the quality of search results—but many are anxious about the collection of personal information by search engines and other websites.
Most search users disapprove of personal information being collected for search results or for targeted advertising
The Pew Internet & American Life survey in February 2012 included several questions probing how respondents feel about search engines and other websites collecting information about them and using it to either shape their search results or target advertising to them.
