Background : Recognising effects of static magnetic field (SMF) varying flux density on flora and fauna is attempted. For this purpose, the influence studied for molecules five complex lipids i.e. such as β-carotene, sphingosine, ceramide, cholesterol phosphatidylcholine. Methods Computations effect real SMF 0.0, 0.1, 1, 10 100 AMFU (Arbitrary Magnetic Field Unit; here 1AMFU > 1000 T) we...

BACKGROUND Intraduodenal bile salts exert negative feedback control on postprandial gall bladder emptying. AIMS We wished to examine whether a similar control mechanism occurs in the fasting state. METHODS Intraduodenal bile salt depletion was achieved by 12 g of cholestyramine. Thereafter, in study A (seven subjects), the effects on gall bladder volume (by ultrasound) and antroduodenal mot...

The HL-60 leukemia cell line derived from a human acute promyelocytic leukemia is stimulated to differentiate into macrophages within 24-48 hr after exposure to the phorbol ester. 1 2-O-tetradecanoylphorbol-1 3-acetate (TPA). We studied early alterations (within 90 mm of exposure to TPA) in phosphatidylcholine metabolism in HL-60 cells and found that phosphatidylcholine synthesis by methylation...

BACKGROUND Evidence has strongly indicated that surface-active phospholipid (SAPL), or surfactant, lines the surface of cartilage and serves as a lubricating agent. Previous clinical study showed that a saturated phosphatidylcholine (SPC), dipalmitoyl-phosphatidylcholine (DPPC), was effective in the treatment of osteoarthritis, however recent studies suggested that the dominant SAPL species at ...

In an extension of the work of Broad & Dawson (1975) on phospholipid biosynthesis in the anaerobic protozoon Entodinium caudatum we have characterized a number of aspects of phosphatidylcholine biosynthesis which, in this organism, is exclusively through the phosphorylcholine, CDP-choline pathway. Initial studies have centred on the subcellular distribution of the enzymes involved in the overal...
