Acid-tolerant poly(3-hydroxybutyrate) hydrolases from moulds [PDF]

open access: yesFEMS Microbiology Letters, 1988
We have isolated some mould strains that can grow under acid conditions with poly(3-hydroxybutyrate) (PHB) as sole carbon source, and secrete PHB hydrolases active at pH values at least down to 3. An improved assay method for such enzymes using a pH stat has been developed, and used to determine the dependence of reaction rate on enzyme and polymer ...

Search for serum biomarkers in patients with bipolar disorder and major depressive disorder using metabolome analysis

open access: yesFrontiers in Psychiatry, 2023
ObjectiveBipolar disorder (BD) and major depressive disorder (MDD) are two common psychiatric disorders. Due to the overlapping clinical symptoms and the lack of objective diagnostic biomarkers, bipolar disorder (BD) is easily misdiagnosed as major ...

Metabolomics Analysis of Amniotic Fluid in Euploid Foetuses with Thickened Nuchal Translucency by Gas Chromatography-Mass Spectrometry

open access: yesLife, 2021
Persistence of a fetal thickened nuchal translucency (NT), one of the most sensitive and specific individual markers of fetal disorders, is strongly correlated with the possibility of a genetic syndrome, congenital infections, or other malformations ...

Synthesis, Characterisation and Detection of Gamma-Hydroxybutyrate Salts. [PDF]

open access: yes, 2012
Sodium, potassium, magnesium and calcium salts of gamma-hydroxybutyrate have been synthesised from gamma-butyrolactone and the corresponding group 1 or 2 hydroxide. Although the group 2 salts are non-hygroscopic, FT-IR spectroscopy and elemental analysis
