Endeavour, 2003
Although chemistry is by far the largest scientific discipline according to any quantitative measure, it had, until recently, been virtually ignored by professional philosophers of science. They left both a vacuum and a one-sided picture of science tailored to physics.

Pharmacology & Therapeutics. Part B: General and Systematic Pharmacology, 1975
The purification of prolactin is simplified by the strong binding of the hormone to pituitary tissue. An extreme alkaline or acidic pH is required to effectively extract prolactin and this provides a convenient way of removing a large number of serum and pituitary proteins by an initial extraction near neutrality.

Cyclotides are head-to-tail cyclic peptides that contain a cystine knot motif built from six conserved cysteine residues. They occur in plants of the Rubiaceae, Violaceae, Cucurbitaceae, and Fabaceae families and, aside from their natural role in host defense, have a range of interesting pharmaceutical activities, including anti-HIV activity.

CHEMISTRY OF THE ATMOSPHERE | Ion Chemistry
2003In this article, we first summarize the production processes for ions, including solar photoionization, photoelectron-impact ionization, and, mostly for X-ray photons, secondary and further electron impact ionization. In the auroral regions, impact of keV electrons and heavier particles is important.

Nature, 1948
DESPITE the revision by Dr. Ridge, "Chemistry for Matriculation" still gives the impression of being old-fashioned both in content and in presentation, although it will presumably meet the rather limited demand for this type of book. The reviewer believes that no text-book of chemistry can go through several editions over many years and still retain ...
