Isopropanol biosynthesis from crude glycerol using fatty acid precursors via engineered oleaginous yeast Yarrowia lipolytica.

Background: Isopropanol is widely used as a biofuel and a disinfectant. Chemical preparation of isopropanol destroys the environment, which makes biological preparation of isopropanol necessary. Previous studies focused on the use of expensive glucose as raw material.

Enhanced CO fixation and lipid production of Chlorella vulgaris through the carbonic anhydrase complex.

Photosynthesis of C. vulgaris shows slow growth and low lipid production due to the low solubility of CO, and it is thus necessary to increase the dissolved inorganic carbon source to solve this problem. In this study, carbonic anhydrase (CA) was fused with dockerin to form a CA complex by cohesion-dockerin interaction.

The change in regional cerebral oxygen saturation after stellate ganglion block.

Background: Stellate ganglion block (SGB) is known to increase blood flow to the innervations area of the stellate ganglion. Near infrared spectroscopy reflects an increased blood volume and allows continuous, non-invasive, and bedside monitoring of regional cerebral oxygen saturation (rSO(2)). We investigated the influence of SGB on bilateral cerebral oxygenation using a near infrared spectroscopy.
