A media consisting of isatin-Schiff bases and its inclusion complexes with β-cyclodextrine was developed to maximize the production of antibiotics Hexaene H-85 and azalomycine B by Streptomyces hygroscopicus CH-7. The media with β-cyclodextrine inclusion complex of isatin-3-thiosemicarbazone resulted in the maximum antibiotics concentration of 493 μg/cm for Hexaene H-85 and 191 μg/cm for azalom...

Due to emerging requirements and pressures related environmental protection, manufacturing enterprises have expressed growing concern for adopting various energy-saving strategies. However, criteria were usually not considered in traditional production scheduling problems. To overcome this deficiency, has drawn more attention from academic scholars industrial practitioners. In paper, an flexibl...

A novel series of isatin-s-triazine hydrazone derivatives has been synthesized and reported herein. The synthetic methodology involved the reaction s-triazine hydrazine precursors with isatin in presence CH3COOH as a catalyst EtOH solvent to afford corresponding target products 6a-e high yields purities. characterization data obtained from elemental analysis, FT-IR, NMR (1H- 13C-) were full agr...

In vivo administration of isatin (200 mg/kg) significantly lowered the activity of rat kidney alkaline phosphatase after 5 hr but enhanced the activity of rat duodenal and jejunal enzyme after 2 and 5 hr (P less than 0.01). The increased activity of the duodenal and jejunal alkaline phosphatase might be due to the induction of the enzyme by isatin.

In the title compound, C16H10N4O2·0.17H2O, prepared by the one-step condensation reaction of isatin with hydrazine hydrate under microwave irradiation, the complete organic mol-ecule is generated by crystallographic inversion symmetry and therefore exists in an S-trans conformation. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, generating a three-dimensional framework with [001...

Accurately predicting the remaining useful life (RUL) of lithium-ion batteries holds significant importance for their health management. Due to capacity regeneration phenomenon and random interference during operation batteries, a single model may exhibit poor prediction accuracy generalization performance under scale signal. This paper proposes method RUL batteries. The is based on improved sp...

Mycoplasma pneumoniae harvested from media which had become acid lost the ability both to induce formation of tetrazolium reduction inhibition antibody and to act as antigens in immunodiffusion against human convalescent-phase sera. Incorporation of N-tris(hydroxymethyl)-2-aminoethane sulfonic acid and N-2-hydroxyethylpiperazine-N'-2-ethane sulfonic acid buffers into a new medium containing PPL...

Ischemic stroke 224 Predictors of poor outcome despite recanalization: a multiple regression analysis of the NASA registry I Linfante, A K Starosciak, G R Walker, G Dabus, A C Castonguay, R Gupta, C-H J Sun, C Martin, W E Holloway, N Mueller-Kronast, J D English, T W Malisch, F A Marden, H Bozorgchami, A Xavier, A T Rai, M T Froehler, A Badruddin, T N Nguyen, M A Taqi, M G Abraham, V Janardhan,...

A fast and convenient protocol for the synthesis of novel spiro[dihydropyridine-oxindole] derivatives in satisfactory yields was developed by the three-component reactions of arylamine, isatin and cyclopentane-1,3-dione in acetic acid at room temperature. On the other hand the condensation of isatin with two equivalents of cyclopentane-1,3-dione gave 3,3-bis(2-hydroxy-5-oxo-cyclopent-1-enyl)oxi...
