A simple and practical method for the determination of caffeine in coffee, black tea and green tea is described. It is based on the extraction and clean-up of caffeine using an Extrelut column and analysis by means of high performance liquid chrom...

Takahashi T., 1983: Properties of syn conjugant clones from total conjugation in pseudourostyla levis ciliophora. In syngen 1 of the hypotrichous ciliate P. levis the characters of synconjugant clones from total conjugation were examined. Three totalor stocks were used with temporaror stocks of other mating types. Of totalors TR-6 has character Tr and OS-1 or...

Fedele, E.; Varnier, G.; Raiteri, M., 1998: In vivo microdialysis study of GABA(A) and GABA(B) receptors modulating the glutamate receptor/NO/cyclic GMP pathway in the rat hippocampus. Intrahippocampal perfusion of bicuculline (50 microM) in Mg2+-free medium caused elevation of extracellular cGMP and epileptic-like behaviour. Both effects were partially prevented by blocking NMDA receptors with MK-801 or Mg2+ ions. Similarly, th...

It is well established that technique failure is one of the main reasons for peritoneal dialysis cessation. Early PD failures occur during the first 6 months of PD and are mainly related to catheter dysfunction and psychosocial problems. Catheter...

Naundorf, G.; Villamil, F.G., 1950: Selective power of 2,4-D. Contribution to the control of red rice. Second note. Comparative trials with 2,4-dichlorophenoxyacetic acid and its sodium salt. The free acid has proved more effective than the sodium salt in inhibiting germination of red rice (Oryza riifipogon). More than double the quantity of the sodium salt is required to obtain the same effect as with the acid. For effective control t...
