BACKGROUND The relapse rate of ulcerative colitis (UC) is high. The efficacy of combined diosmectite and mesalazine treatment for active mild-to-moderate UC was investigated. MATERIAL/METHODS A total of 120 patients with UC were enrolled in this randomized, single-blind, placebo-controlled study. Sixty patients were assigned to the Diosmectite group (diosmectite and mesalazine) and 60 were as...

Laboratory studies have indicated that calcite may be used in separate, exchangeable filter units in constructed wetland systems to remove phosphorus. Based on these studies we built a full-scale experimental constructed wetland with a calcite-based filter unit to study its performance, under real-life conditions. The system consists of a 2-m3 sedimentation tank and two vertical flow constructe...

The transfecting activity of Bacillus phage varphi29 DNA, extracted either by sodium lauroyl sarcosine-phenol or by 2 M perchlorate, was destroyed by treatment with proteolytic enzymes, although these enzymes did not effect transfecting DNAs of SPP1, SPO1, and SP50. These facts suggest that a protein is associated with transfective varphi29 DNA. Stabilization of protease-resistance during trans...

Biomass harvesting is a bottleneck in microalgae culture and microalgae-based wastewater treatment systems. Sedimentation coupled to coagulation flocculation has been experimentally studied for long time, however, full scale sedimentation experiences have not addressed so far literature, scaling up from experimental results may be straightforward. The aim of this study was evaluate the performa...

Grupi and Kashkan marl formations comprise a considerable part of Zagros region. These formations have a considerable erodibility and sedimentation potential because of their special geological and mineralogical characteristics. The objective of this study was to compare the erosion and sediment yield of Kashkan and Grupi formations in Merk watershed located in southeast Kermanshah, using the M...

We have reviewed 60 patients with primary bone infections; 21 of these (35%) had subacute osteomyelitis, a figure which supports other recent observations that this variant of bone infection is becoming more widespread. In this group open culture and biopsy were necessary in order to exclude bony malignancy, and a raised erythrocyte sedimentation rate proved a useful diagnostic aid. All the pat...

The results of the conducted studies allow us to conclude that an increase in number micelles per unit volume grouting solution will lead its sedimentation stability. desired effect can be achieved by increasing concentrations surfactants mixing fluid or introducing electrolyte. Since presence sites with adsorbed surfactant additive on surface dispersed phase particles significantly changes con...
