In this paper, we introduce and study an efficient regular queries processing algorithm on a very large XML data set which is fragmented and stored on different machines. The machines are connected by the high speed interconnection. In this system the efficiency of a query processing algorithm depends on two main factors: the waiting time for the answer and(More)
BACKGROUND AND PURPOSE Exogenous peroxynitrite from nanomolar to micromolar concentrations exerts cardioprotection. Here, we have assessed its effects on ischaemia- and reperfusion-induced ventricular arrhythmias in vivo and a possible role for mitochondrial K(ATP) channels in these effects, using the channel inhibitor 5-hydroxydecanoate (5-HD).

In 6 male subjects the diurnal variation of urinary oxalic acid excretion was studied after ingestion of chocolate, a food stuff rich in oxalic acid. The ingestion of chocolate caused a striking but transient increase in urinary oxalic acid excretion due to its absorption in the upper gastrointestinal tract. The peak excretion rates occurred 2-4 h after the(More)
The most aggressive and rare manifestation of multiple myeloma is plasma cell leukaemia (PCL). While secondary form of PCL represents those heavily pretreated cases when leukaemic transformation develops terminally after intensive chemotherapy in patients with multiple myeloma, primary cases are characterized by leukaemic symptoms present at diagnosis. The(More)
RDF is a flexible data representation model. Due to its flexibility and simplicity it has become a popular framework, hence the amount of RDF data is increasing fast. Querying massive amount of data is a serious challenge in general and it is true for RDF data as well. In this paper we investigating how to evaluate SPARQL queries on a distributed system. We(More)
The aim of this study was to see whether pleiotropic or myeloid hematopoietic growth factors, which do not stimulate normal lymphoid cells, can induce proliferation of blast cells of the acute lymphoid leukemia (ALL) of childhood. Bone marrow cells of 13 children with untreated ALL (nine common ALL, two myeloid antigen positive ALL and two early T-cell ALL)(More)
Our preliminary data indicate that rosiglitazone may be myeloprotective. We investigated whether it can modify bone marrow recovery. Five-day pre-treatment with rosiglitazone significantly accelerated recovery of 5-fluorouracil-damaged bone marrow in mice. Frequency and femoral content of granulocyte-macrophage progenitors reached mean baseline faster in(More)
Neuropathological examination of the gut in a patient with chronic idiopathic intestinal pseudoobstruction and temporal lobe epilepsy showed a degeneration of Auerbach's and of Meissner's plexus. The extent of degenerative changes increased in an aboral to oral direction. Neuronal degeneration was characterized by ballooning of the cytoplasm of the ganglial(More)
INTRODUCTION Fludarabine is the most commonly used purine analog, its mechanism of action is complex. Fludarabine inhibits DNA synthesis, acts on non-dividing (G0 phase) cells influencing apoptosis. PATIENTS, RESULTS, CONCLUSIONS In our institute 47 patients were treated with fludarabine or fludarabine based combination chemotherapy. Fludarabine was given(More)
