To investigate a novel β-glucosidase from Bifidobacterium breve ATCC 15700 (BbBgl) to produce compound K (CK) via ginsenoside F2 by highly selective and efficient hydrolysis of the C-3 glycoside from ginsenoside Rd, the BbBgl gene was cloned and expressed in E. coli BL21. The recombinant BbBgl was purified by Ni-NTA magnetic beads to obtain an enzyme with specific activity of 37 U/mg protein using pNP-Glc as substrate. The enzyme activity was optimized at pH 5.0, 35°C, 2 or 6 U/ml, and its activity was enhanced by Mn<sup>2+</sup> significantly. Under the optimal conditions, the half-life of the BbBgl is 180 h, much longer than the characterized β-glycosidases, and the Km and V<sub>max</sub> values are 2.7 mM and 39.8 μmol/mg/min for ginsenoside Rd. Moreover, the enzyme exhibits strong tolerance against high substrate concentration (up to 40 g/l ginsenoside Rd) with a molar biotransformation rate of 96% within 12 h. The good enzymatic properties and gram-scale conversion capacity of BbBgl provide an attractive method for large-scale production of rare ginsenoside CK using a single enzyme or a combination of enzymes.

Investigating the electrochemical windows of ionic liquids

Maan Hayyan,Farouq S. Mjalli,Mohd Ali Hashim,Inas M. AlNashef,Tan Xue Mei 한국공업화학회 2013 Journal of Industrial and Engineering Chemistry Vol.19 No.1
The structure effect on the electrochemical windows (EWs) was studied using cyclic voltammetry (CV) in 16 ionic liquids (ILs), consisting of various cations such as piperidinium, pyridinium, pyrrolidinium,phosphonium, morpholinium, ammonium, sulfonium and imidazolium, and anions including bis(trifluoromethylsulfonyl)imide, tris(pentafluoroethyl)trifluorophosphate, dicyanamide, trifluoroacetate and trifluoromethanesulfonate. It was found that all studied ILs have good EWs to be utilized as electrolytes in different electrochemical applications pertaining to industry. Furthermore, it was found that the structure of ILs affected the EW and both the cation and anion have important effect on the reductive and oxidative limits, respectively. The reductive limits of the studied ILs were found to follow the sequence of [P14,666]+ > [N112,1O2]+ > [HMPyrr]+ > [BMPyrr]+ > [EMIm]+ > [MOEMMor]+≈[MOPMPip]+ > [S222]+ > [BMPy]+≈[HPy]+≈ [HPPy]+. The oxidative limits were found to follow the sequence of [TFSI]ˉ > [TPTP]ˉ > [TfO]ˉ > [DCA]ˉ > [TFA]ˉ. 2012 The Korean Society of Industrial and Engineering Chemistry. Published by Elsevier B.V.

Background and Purpose To explore the causal relationships of elements of the exposome with ischemic stroke and its subtypes at the omics level and to provide evidence for stroke prevention. Methods We conducted a Mendelian randomization study between exposure and any ischemic stroke (AIS) and its subtypes (large-artery atherosclerotic disease [LAD], cardioembolic stroke [CE], and small vessel disease [SVD]). The exposure dataset was the UK Biobank involving 361,194 subjects, and the outcome dataset was the MEGASTROKE consortium including 52,000 participants. Results We found that higher blood pressure (BP) (systolic BP: odds ratio [OR], 1.02; 95% confidence interval [CI], 1.01 to 1.04; diastolic BP: OR, 1.03; 95% CI, 1.01 to 1.05; pulse pressure: OR, 1.03; 95% CI, 1.00 to 1.06), atrial fibrillation (OR, 1.18; 95% CI, 1.13 to 1.25), and diabetes (OR, 1.13; 95% CI, 1.07 to 1.18) were significantly associated with ischemic stroke. Importantly, higher education (OR, 0.69; 95% CI, 0.60 to 0.79) decreased the risk of ischemic stroke. Higher systolic BP (OR, 1.06; 95% CI, 1.02 to 1.10), pulse pressure (OR, 1.08; 95% CI, 1.02 to 1.14), diabetes (OR, 1.28; 95% CI, 1.13 to 1.45), and coronary artery disease (OR, 1.58; 95% CI, 1.25 to 2.00) could cause LAD. Atrial fibrillation could cause CE (OR, 1.90; 95% CI, 1.71 to 2.11). For SVD, higher systolic BP (OR, 1.04; 95% CI, 1.00 to 1.07), diastolic BP (OR, 1.06; 95% CI, 1.01 to 1.12), and diabetes (OR, 1.22; 95% CI, 1.10 to 1.36) were causal factors. Conclusions The study revealed elements of the exposome causally linked to ischemic stroke and its subtypes, including conventional causal risk factors and novel protective factors such as higher education.
