A recombinant α-dioxygenase from rice to produce fatty aldehydes using E. coli.

Fatty aldehydes are an important group of fragrance and flavor compounds that are found in different fruits and flowers. A biotechnological synthesis of fatty aldehydes based on Escherichia coli cells expressing an α-dioxygenase (αDOX) from Oryza sativa (rice) is presented. α-Dioxygenases are the initial enzymes of α-oxidation in plants and oxidize long and medium-chain C(n) fatty acids to 2-hydroperoxy fatty acids.

Pentraxin 3 is elevated in haemodialysis patients and is associated with cardiovascular disease.

Background: Pentraxins are mediators of inflammation as well as markers of the acute-phase reaction. While elevation of C-reactive protein (CRP) in patients with renal failure and its association with cardiovascular disease is well described, there are no data on pentraxin 3 (PTX3) in this population.

Methods: Plasma was obtained from 44 chronic haemodialysis (HD) patients, 35 peritoneal dialysis (PD) patients, 39 patients with chronic renal failure (CRF) not on dialysis therapy and 14 age-matched normal subjects.
