With moltensulfurit reacts violently to produce polysulfides; under more controlled conditions it reacts with organic solutions of sulfur. Liquidseleniumandtelluriumboth react vigorously with solid...
Essential oils have a high volatility that leads to evaporation and loss of their pharmacological effect when exposed to the environment. The objectives of the present work were to prepare microcapsules with oregano essential oil by extrusion using sodium alginate as a shell material and non-ionic ...

After pre-incubation, 135 μL of p-NP-laurate (2.5 mM, in 5 mM sodium acetate buffer, pH 5.0, with 1% Triton X-100) was added to start the reaction and was incubated at 37 °C, for 2 h. The absorbance was measured at 405 nm using a microplate reader. The inhibitory activity ...
Modified ortho-pathway enzymes (catechol 1,2-dioxygenase II, muconate cycloisomerase II, dienelactone hydrolase, and maleylacetate reductase) were induced in Pseudomonas putida strain 87 grown on 3-chlorobenzoic acid as the only carbon and energy source. Catechol 1,2-dioxygenase II, the key enzyme...
Folin–Ciocalteu reagent, 2,2′-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS), boron trifluoride (BF3) and diethyl ether were purchased from Sigma (St. Louis, MO, USA). Ninhydrin, hydrindantin, methylcellosolve and sodium acetate buffer were purchased from INGOS (Prague, Czech Re...
Four sera of patients with AOSD were mixed with 50 mM sodium acetate (Sigma Aldrich, Germany), Ph4.8, heated at 70 °C for 10 min and centrifugated at 15000 g for 30 min at 4 °C. Maintaining the solution at PH 5.2 (4 °C), ammonium sulfate (Sigma Aldrich, Germany) (50% of sat...
The activities of amylase and protease were observed at pH 5–11 and pH 1–11, respectively. Buffers used (0.2 M) comprised KCl–HCl (pH 1.0), glycine–HCl (pH 2.0 and 3.0), sodium acetate (pH 4.0 and 5.0), sodium phosphate (pH 6.0 and 7.0), Tris-HCl (pH 8.0 and 9.0), and ...
