We investigated the association between 3 main proinflammatory cytokines [interleukin (IL)-1β and IL-6] and the risk of acute pancreatitis. Polymerase chain reaction-restriction fragment length polymorphism was used to genotype IL-1β+3954 C/T (rs1143634) and IL-1β-511 C/T (rs16944) and IL-6 -174 G/C (rs1800795) and IL-6 -634 C/G (rs1800796). The genotype distributions of IL-1β+3954 C/T (rs11436...

Friction stir welding (FSW) is a promising technique to join aluminum alloys without having problems encountered during fusion welding processes. In the present work, the evolution of microstructure and texture in friction stir welded thin AA2024 aluminum alloy are examined by electron backscattered diffraction (EBSD) technique. The sheets with 0.8 mm thickness were successfully welded by frict...
