fresh frozen plasma (ffp) and prothrombin complex concentrate (pcc) reverse oral anticoagulants such as warfarin. we compared the standard dosage ffp and pcc in terms of efficacy and safety for patients with mechanical heart valves undergoing interventional procedures while receiving warfarin. fifty patients were randomized (25 for each group) with mechanical heart valves [international normali...

The effect of theta pulse stimulation (TPS) on pentylenetetrazol (PTZ)-induced long-term potentiation of population spikes (PS) was studied in the hippocampal CA1 in vitro. A transient PTZ application produced a long-lasting enhancement of PS amplitude. A 3-min episode of TPS delivered at a higher intensity produced complete reversal of the PTZ potentiation when delivered during the last minute...

background: the effects of aqueous extract of fadogia agrestis stem at the doses of 18, 36, and 72 mg/kg body weight on alloxan-induced toxicity was investigated in wistar rats. methods: in total, 35 rats of both sexes (132.80±7.22g) were randomized into five groups (a-e): animals in group a received 0.5 ml of distilled water orally on daily basis for 15 days while the alloxanized rats in group...

A d-dimensional zero-one matrix A avoids another d-dimensional zero-one matrix P if no submatrix of A can be transformed to P by changing some ones to zeroes. Let f(n, P, d) denote the maximum number of ones in a d-dimensional n × · · · × n zero-one matrix that avoids P . Fox proved for n sufficiently large that f(n, P, 2) = 2k Θ(1) n for almost all k × k permutation matrices P . We extend this...

operating parameters and membrane characteristics strongly affect the performance of electrodialysis reversal systems. the most impactful factors are applied voltage, flow rate, temperature, initial feed composition, and ion exchange membrane characteristics; the ph of the feed also has an effect, although to a lesser extent. to determine more precisely how all of these factors impact performan...

Wigner’s little groups are the subgroups of the Lorentz group whose transformations leave the momentum of a given particle invariant. They thus define the internal space-time symmetries of relativistic particles. These symmetries take different mathematical forms for massive and for massless particles. However, it is shown possible to construct one unified representation using a graphical descr...

Let S be a subset of the positive integers, and let σ be a permutation of S. We say that σ is a k-avoiding permutation of S if σ does not contain any k-term AP as a subsequence. Similarly, the set S is said to be k-avoidable if there exists a k-avoiding permutation of S.

analytic hierarchy process (ahp) has been criticized considerably for possible rank reversal phenomenon caused by the addition or deletion of an alternative. while in many cases this is a perfectly valid phenomenon, there are also many cases where ranks should be preserved. our findings indicate that using the geometric mean reduces the variance in ratings substantially; hence, yielding lower i...
