Dried and ground leaves of Crithmum maritimum were used as a matrix for supercritical extraction of volatile oil with CO2. Operative conditions were: extractor, 90 bar and 50 °C for 240 min; first separator, 90 bar and –10°C; second separator, 15 bar and 15 °C. GC/MS analysis of the leaves volatile oil revealed that it mainly consisted of: para-cymene, βphellandrene, γ-terpinene, thymol methyl ...

Osmotic dehydration kinetics of beetroot cubes in sucrose solution having different concentrations (30?Brix, 45?Brix and 60?Brix), solution temperature 35, 45 and 55 ?C, sample to solution ratio 1:4 were studied up to 240 min duration. For osmotic dehydration of beetroot in solution of sucrose the effect of all process parameter were significant at 5% level of significance on both water loss an...

und 5-Joduracil wurde bei 260 und 280 m//, von Cytosin bei 265 und 280 m/u, von Naphthoimidazol bei 230 und 240 m/*, von 5.6-Dimethylbenzimidazol bei 245 und 260 m/ii, von 6-Azauracil bei 250 und 280 mju und von 8-Azaguanin bei 255 und 275 m/u verfolgt. Eine Inkubationsdauer von 60 Min. reicht im allgemeinen vollständig, um einen deutlichen Effekt zu erhalten. Bei längerer Inkubation (3 Stdn.) ...

An inexpensive, simplified flow model for use with digital subtraction angiographic (DSA) equipment is described. System tests show that the model gives reproducible data with a standard deviation of +/- 2.6%. Flow analysis also reveals an appropriate response to flow rates of 20-240 ml per min. The flow model can be used to investigate many of the variables and sources of error in DSA flow mea...

This study optimized a co-solvent free electrochemical method for biodiesel synthesis using graphite electrode and waste concrete heterogeneous catalyst. Various parameters were evaluated, including: applied voltage (9.6, 14.4, 19.2 V), catalyst particle size uniformity (unfiltered filtered with 150 mesh), reaction time (15, 30, 120, 240 min). The results obtained 100% FAME content 78.51% of yi...

The pharmacokinetics of cefoperazone were evaluated in 25 infants (mean age, 26 days) after intramuscular and intravenous routes of administration. The levels in blood that were achieved were severalfold higher than those required to inhibit common pathogens. The mean half-life of 240 min was one-half of that observed in 1- to 2-day-old infants but about twice that seen in adults. Further evalu...

The dentate gyrus (DG) engages in sustained Arc transcription for at least 8 hours following behavioral induction, and this time course may be functionally coupled to the unique role of the DG in hippocampus-dependent learning and memory. The factors that regulate long-term DG Arc expression, however, remain poorly understood. Animals lacking Egr3 show less Arc expression following convulsive s...

UNLABELLED The alpha(v)beta3 integrin plays an important role in metastasis and tumor-induced angiogenesis. Targeting with radiolabeled ligands of the alpha(v)beta3 integrin may provide information about the receptor status and enable specific therapeutic planning. Previous studies from our group resulted in tracers that showed alpha(v)beta3-selective tumor uptake. However, these first-generati...
