Lecithin: Cholesterol acyltransferase, lipoprotein lipase and lipoproteins in adult Nigerians with sickle cell disease
Lecithin: Cholesterol acyltransferase (LCAT) is a glycoprotein enzyme involves in the esterification of plasma cholesterol to form cholesteryl ester and is important in the maturation of high density lipoprotein. Lipid metabolism in sickle cell anaemia patients may be affected. The objective of this study was to determine the activities of serum lecithin: cholesterol acyltransferase, lipoprotein lipase, lipids and...

The response to iron deficiency of two sensitive grapevine cultivars grafted on a tolerant rootstock
Two sensitive cultivars were examined, Vittoria and Italia, grafted on a tolerant rootstock (140 Ruggeri). Two levels of iron chlorosis in scions were selected, initial and evident, and compared to the healthy rootstock (control). The fractions of extracellular and cytoplasmatic cations, chloroplastic mobile, loosely linked, strongly linked and residual cations as well as the active fraction were...

Effects of soaking and boiling and autoclaving on nutritional quality of Mucuna flagellipes (Ukpo)
The effect of soaking and boiling, and autoclaving on nutritional factors (proximate and mineral) and anti-nutritional qualities of legume, Mucuna flagellipes were studied. Batches of seeds were soaked for 6, 12, 18 and 24 h in distilled water at room temperature, then boiled in water for 30, 45, 60 or 90 min respectively. Another batch of the M. flagellipes was autoclaved for different duration of...
