Objective: To measure pancreatic and non-pancreatic phospholipase A2 activity in human acute necrotising pancreatitis.

Design: Prospective study.

Setting: University hospital, Finland.

Subjects: 20 patients with acute necrotising pancreatitis.

Interventions: Serum and urine samples were taken daily for a week and fluid from peritoneal lavage for six days after admission. Samples from the pleural cavity were taken from patients in whom pleural drainage was considered necessary. Pancreatic tissue was recovered from the patients who were operated on for acute pancreatitis or for pancreatic tumour.

Main Outcome Measures: Serum phospholipase A2, amylase, and lipase activities.

Results: Serum phospholipase A2 activity increased up to eightfold, 25.0 (5.4) IU/L (n = 20, range 9.0-77 IU/L) (reference value <3 IU/L) and remained high during the first week, whereas serum amylase and lipase returned to the reference range during the first four days. The maximal phospholipase A2 activity in urine was 4.5 IU/L, in the fluid from peritoneal lavage 16.9 IU/L, and in the fluid from the pleural cavity 37.0 IU/L. Phospholipase A2 activity in necrotic pancreatic tissue ranged from 0.25 to 5.70 IU/g and in normal pancreatic tissue from 9.85 to 15.0 IU/g. Preincubation at 60 degrees C showed non-pancreatic phospholipase A2 activity predominated in serum, whereas part of the enzyme activity in the fluids from pleural cavity and peritoneal lavage proved to be of pancreatic derivation.

Conclusions: The results suggest a role for both pancreatic and non-pancreatic phospholipase A2 in acute pancreatitis. Preincubation at 60 degrees C proved useful in the differentiation between pancreatic and non-pancreatic phospholipase A2 activity.

We compared the enzymatic, coagulant, and neuromuscular activities of two variants (yellow-CDRy and white-CDRw) of venom with a sample of (CDT) venom and examined their neutralization by antivenom against CDT venom. The venoms were screened for enzymatic and coagulant activities using standard assays, and electrophoretic profiles were compared by SDS-PAGE. Neutralization was assessed by preincubating venoms with crotalic antivenom and assaying the residual activity.

Background: Dynamins are defined as a group of molecules with GTPase activity that play a role in the formation of endocytic vesicles and Golgi apparatus. Among them, DNM3 has gained recognition in oncology for its tumor suppressor role. Based on this, the aim of this study is to investigate the effects of the DNM3 gene in patients diagnosed with pancreatic cancer using bioinformatics databases.

This study investigated the mechanisms employed by exogenous dopamine application in alleviating chilling injury in kiwifruits during storage at 1 °C for 120 days. Our results indicated that dopamine treatment at 150 µM alleviated chilling injury in kiwifruits during storage at 1 °C for 120 days. By 150 µM dopamine application, higher SUMO E3 ligase (SIZ1) and target of rapamycin (TOR) genes expression accompanied by lower poly(ADP-Ribose) polymerase 1 (PARP1) and sucrose non-fermenting 1-related kinase 1 (SnRK1) genes expression was associated with higher salicylic acid, ATP, NADPH and proline accumulation in kiwifruits during storage at 1 °C for 120 days.
