Background Development of bioprocesses for mammalian cells has to deal with different bioreactor types and scales. Bio-reactors might be intended for seed train and production, research, process development, validation or transfer purposes. During these activities, not only the problem of upand downscaling might lead to failure of repro-ducibility, but also the use of different bioreactor geome...

Formaldehyde (FA) is a very toxic pollutant. FA in indoor air has a negative effect on human health and should be removed by ventilation or by conversion to non-toxic products. The formaldehyde dehydrogenase (FdDH), a NADand glutathione-dependent enzyme from recombinant methylotrophic yeast Hansenula polymorpha, was tested for its ability to oxidize airborne FA. A continuous fluidized bed biore...

In recent years, the weakness of the canonical support-confidence framework for associations mining has been widely studied. One of the difficulties in applying association rules mining is the setting of support constraint. A high-support constraint avoids the combinatorial explosion in discovering frequent itemsets, but at the expense of missing interesting patterns of low support. Instead of ...

The sinus lift techniques had a lot of modifications through the years. In 1960 Boyene published sinuslift with lateral access. In the beginning it was used for achieving an optimal intercrestal distance needed for denture making. But in the 1980 Boyen and James started to place implants in the newly created bone. The wish of patients and dentists for minimalivasive methods lead to the developm...

T freezing of water and melting of ice are among the most dramatic examples of phase transitions in nature. Melting ice accounts for everyday phenomena as diverse as the electrification of thunderclouds, in which the liquid layer on ice chunks facilitates the transfer of mass and charge during collisions between them; frost heave powerful enough to lift boulders from the ground (see PHYSICS TOD...

Objective: To reemphasize LIFT technique for fistula in ano with redefined inclusion and exclusion criteria developed by Thai surgeon Arun Rojanasakul & to standardize the procedure for our setting. Material & Method: A prospective observational study in 32 fistula in ano patients treated by LIFT technique from Sept 2011 to March 2013. Result: Fistula in ano healed primarily in all 32 patients ...

For the first time three different natural compounds, isolated from hairy roots of Astragalus membranaceus, cultivated in airlift bioreactor were tested for their cytotoxic potential and apoptosis induction in a panel of human tumor cell lines. Root cultures, cultivated in bioreactor gave 18.5 g l(-1) dry wt roots with the highest astragaloside production in vitro up to now - 1.64% (astragalosi...

In the wake of intensive fossil fuel usage and CO2 accumulation in the environment, research is targeted toward sustainable alternate bioenergy that can suffice the growing need for fuel and also that leaves a minimal carbon footprint. Oil production from microalgae can potentially be carried out more efficiently, leaving a smaller footprint and without competing for arable land or biodiverse l...

INTRODUCTION: Numerous facelift techniques are employed across aesthetic surgeons, but all can be categorized according to the specific plane(s) of dissection. Regardless of the technique, nerve injuries are ubiquitously feared complications. The dissection plane has been implicated in the rates of nerve injuries, but little consensus exists on the exact relationship. Our aim was to perform a s...
