Pancreatic phospholipase A2 activity in acute pancreatitis: A prognostic marker for early identification of patients at risk [PDF]
, 2002 Remarkably elevated levels of phospholipase A(2) (PLA(2)) are measurable in human blood samples in cases of acute pancreatitis. The source of the enzyme was first thought to be exclusively the pancreas, but now it is generally accepted that two ...

Effect of fibre treatments on interfacial shear strength of hemp fibre reinforced polylactide and unsaturated polyester composites [PDF]
, 2011 Surface treatment of hemp fibres was investigated as a means of improving interfacial shear strength (IFSS) of hemp fibre reinforced polylactide (PLA) and unsaturated polyester (UPE) composites. Fibres were treated with sodium hydroxide, acetic anhydride,
