Anhydrovitamin A2 and Rehydrovitamin A2

Anhydrovitamin A, and Rehydrovitamin A,. II

In a previous publication (l), we reported that when 1 mg of a pure concentrate of anhydrovitamin A2 (4’-ethoxy anhydrovitamin Ai, E:%m at 370 rnp = 2248 in light petroleum ether), and 0.5 mg of a-tocopherol are fed daily to vitamin A-deficient rats, growth is resumed, xerophthalmic lesions are cured, and a new compound named rehydrovitamin A* showing absorption maxima at 330,348, and 365 rnp c...

Thromboxane A2, and ADP

In monkeys with early and advanced atherosclerosis, we examined responses to the three major vasoactive agonists that are released when platelets aggregate. Measurements were obtained in normal cynomolgus monkeys and in monkeys fed an atherogenic diet for 4+1, 9±1, and 19±1 months (mean± SEM). Morphometry of femoral and iliac arteries indicated that 4 months of atherogenic diet produced only sl...

Lysosomal phospholipase A2 and phospholipidosis.

A lysosomal phospholipase A2, LPLA2, was recently characterized and shown to have substrate specificity for phosphatidylcholine and phosphatidylethanolamine. LPLA2 is ubiquitously expressed but is most highly expressed in alveolar macrophages. Double conditional gene targeting was employed to elucidate the function of LPLA2. LPLA2-deficient mice (Lpla2-/-) were generated by the systemic deletio...

A2-web immanants

Abstract. We describe the rank 3 Temperley-Lieb-Martin algebras in terms of Kuperberg’s A2-webs. We define consistent labelings of webs, and use them to describe the coefficients of decompositions into irreducible webs. We introduce web immanants, inspired by Temperley-Lieb immanants of Rhoades and Skandera. We show that web immanants are positive when evaluated on totally positive matrices, an...
