Complexes of beta -cyclodextrin with various salts of ibuprofen are described in which the molar ratios of ibuprofen to beta -cyclodextrin are within the range of from 1:0.20 to 1:0.75. The preferred salt of ibuprofen is the sodium salt. The complexes have enhanced taste profile and bioavailability. Also disclosed are methods for preparing the complexes and also pharmaceutical compositions there...

A method is provided wherein betaine is separated eluted from beet molasses using a chromatographic simulated moving bed system having at least three chromatographic columns connected in series. The betaine is eluted during the same cycle as sucrose and rest molasses as a third fraction. The method comprises a molasses feeding and substantially simultaneous water feeding step, at least one water f...

The new DNA(YEP1) having promotor activity in E.coli and yeast and its purification method are presented. Thus, DNA extracted from yeast is treated with restriction enzyme AluI and HaeIII, and DNA with 500-2500 base pairs is obtained by electrophoresis in 1% agarose gel. The obtained DNA is treated with restriction enzyme BamHI and ligated into pk15 vector using T4 DNA ligase. E.coli LE392 tran...

The method for preparing fusion enzyme and peptide coded with pre-S2 in transformed E. coli cells by recombinant DNA techniques comprises: (a) preparing the vector having nucleotide sequence coding amino terminal of transcription and translation activating sequence polypeptide, nucleotide sequence coded with pre-S2 among HBsAg gene regions of hepatitis virus B and DNA sequences ligated with transl...

In the method, PCT10 is treated with BamHI in buffer II to give 1.1 kb DNA segment containing β-galactosidase sequence. The segment is treated with Sau3A to get 600 bp DNA segment to code N-terminal 200 amino acids of β-galactosidase. The segment is ligated with PUC18 to give PUCCT30 (KCTC 83249). PUCCT 30 is treated with BamHI and SalI to give 600 bp DNA segment, which is ligated with pT-6IN ...

Thread apparatus which comprises a driving part 10 and a driven part 24. Arranged between the driving part and the driven part there are clutch elements with carriers 18, 22, 70 which, when torque is transmitted between the driving part 10 and the driven part 24, are in engagement with each other. When a predetermined torque is exceeded, these carriers 18, 22, 70 are disengaged by means of one of ...

The invention concerns a power line switch placed in connection with an electrical pole 1 or the like by which the electrical current in the power line can be shut off. In the power line switch the electrical current is taken via current path elements 6, 7 connected to the power line which in order to cut off the current can be separated from each other using a power cut-off mechanism. The power c...
