From reading Dr. Mase's informative post, I have learned about the effects of growth hormones injected into dairy and beef cows. The main hormone used to increase the productivity of these cows is called rBGH (recombinant bovine growth hormone) and has been found to be harmful for human consumption. rBGH is marketed under the name Posalic and was approved by the FDA in 1993 despite claims that its effects were not tested properly or sufficiently.
From Ev Cohen's insightful report on pasteurization I have learned of the benefits of this TUBULAR process. Pasteurization is the process of heating food/wine/beer to a temperature are which harmful microorganisms, which can spoil food and/or be harmful to the human body, are killed. Additionally, with our recent economical depression, pasteurization is the best thing possible for America, home of the brave.

Chemistry of Allergies and the Human Body
The term allergy has Greek roots, derived from allos meaning “other” and ergon meaning “reaction.” What we know as ‘allergies’ are actually considered to be a Type I Hypersensitivity. A Type I Hypersensitivity is caused by excessive activation of mast cells by the stimulus immunoglobulin E. The body’s response to this excessive activation is what causes symptoms ranging from watery eyes to sudden death.
The first real research done on allergies was in 1906 with Baron Clemens von Pirquet, a Viennese pediatrician. Clemens von Pirquet established basic knowledge about hypersensitivity, coined the term ‘allergy’, and noted common allergens. Since then, doctors have been researching how to prevent and treat allergies, as well as the chemistry behind them.
Most people are familiar with the common reactions to certain allergens. Allergic reactions can be local or systemic and obviously vary from allergen to allergen, and from person to person. Systemic reaction is called anaphylaxis and it is much more severe than local reactions, often resulting in hypertension, coma, or death.
I’ve included this diagram on the right from Wikipedia because I found it very helpful at quickly getting a general understanding of the biology involved. Immunoglobulin E (IgE) is the antibody produced by the body once an allergen is introduced. Once the antibodies encounter the allergen again, they react triggering a bodily response. Immunoglobulin E does have a positive use in the body however: IgE has been observed to help the body resist diseases carried by parasites such as Lyme disease. (Interestingly, IgE has only been found in mammals to date)
Current allergy medications aim to treat the symptoms of common allergic reactions, but currently, chemists are working to stop the problem at the source by neutralizing IgE before it can react. Recent breakthroughs have allowed chemists to determine the structure of IgE (which is unlike other antibodies because of its long and bent shape) hopefully making it easier to develop a treatment.

See children, drugs are bad
Heroin and Crystal Meth are poor for your health.
If you want to lead a healthy, long, vibrant, fertile life, don't do them. Not even once. They'll ruin your eyesight. Especially when consumed through certain body parts (hint: it's called 'bumming').
- Coca Cola
- Several cats
- Constructing Model Rockets
- Rapping
- Christmas shopping
- A healthy addiction to chemistry (particularly of the organic sort)
- Collecting porcelain dolls (usually goes hand in hand with the 'several cats' option)
- Blogging
- Volunteering
- Getting a job
LOL
Chem is for Squares (and Hunter-Gatherers)
Take the bassline out... No? You don't have to.
