A comprehensive treatise on new developments in biotechnology, the
authors of Biotechnology and Safety Assessment, 3e, bring readers
an up-to-date review of food safety issues, pre-clinical safety and
development of new foods and drugs, plant biotechnology, food
allergies and safety assessment, and consumer benefits with regard
to genetically modified food.
Tomorrow's foods will be obtained from genetically modified crops,
offering consumers higher nutritional value and more of it. Our
medications will be obtained through a variety of biotechnological
procedures yielding more potent and specific medications for
diseases and vaccines. In order to make this view of the future
come to light, John A. Thomas and Roy L. Fuchs have updated their
classic in order to keep readers one step ahead.
Written by internationally recognized molecular biologists, plant
agronomists, microbiologists, toxicologists, nutritionists, and
regulatory authorities, this third edition is an excellent and
authoritative resource, making it a valuable resource to any
biomedical library or scientific bookshelf.

The use of performance-enhancing substances by athletes is not a
contemporary epi demic. In fact, athletes purportedly resorted to
such measures over 2000 years ago. Even at the ancient olympic
games, athletes employed special diets and concoctions to enhance
their performance. In ancient Rome and ancient Egypt, gladiators
and athletes ingested various potions in order to improve their
physical endurance. In most in stances, such early examples of
substance abuse by athletes involved relatively in nocuous
chemicals, and one might presume that any enhanced performance
could be attributed largely to a placebo effect. Nowadays, aside
from the ethical issues, these performance-enhancing substances are
far more potent and hence toxic to the body. The many
performance-enhancing chemicals, drugs, and hormones exert a
variety of complex pharmacological actions, but all are meant in
some fashion to improve phys ical ability. Their pharmacological
effects ranges from imprOVed muscle strength, as in the case of
anabolic steroids and growth hormone, to central nervous system
stimula tion, as in the case of caffeine or amphetamine. Analgesics
or other pain-killing drugs may also be used to suppress an
existing injury in order that the athlete may compete."
The authors have provided an overview of the relationships between
hormones that are physiologic constituents of the body as well as
their pharmacologic use in replacement therapies and related
endocrine dys function. Principles of Endocrine Pharmacology
concerns itself with the ther apeutic use of hormones, and hormone
like substances, or drugs that can act either by suppressing or
enhancing the metabolism of certain glands of internal secretion.
Other drugs used for nonendocrine ther apies can likewise affect
the endocrine system. Endocrine pharmacology emerged in the early
1900s with the use of crude pituitary extracts. By the mid-1900s
several investigators had isolated and begun to synthesize hormones
or hormonelike substances. Recognizing the limited supply of
hormones that could be obtained both from animal sources and human
autopsy material, the search for so called hormone substitutes also
began early in the 1900s. Recently, re combinant DNA technologies
have been used to provide alternative therapeutic sources of human
insulin and human growth hormone. Aside from insulin, perhaps no
other use of hormonally-active sub stance is better exemplified by
those drugs which affect fertility. The synthesis of an
orally-effective steroid represented one of the first major
breakthroughs in the chemical suppression of ovulation. Since the
orally active 19-norsteroids were introduced in the 1950s, several
oral contra ceptive steroid preparations have been marketed.
Indeed, the advent of oral contraceptives for birth control has led
to a renewed interest in endocrine pharmacology."
Literal Genesis identifies and corrects the key errors of evolution
and young-earth creationism, then combines their truths to suggest
a simple yet scientifically and scripturally accurate new
Synthesis.
Embrace wisdom and improve your life, step by step, day by day, in
