Opis:
The aim of the study was to answer the question whether or not determination of C-reactive protein in patients after serious abdominal surgeries can be prognostic of septic complications.Material and methods. 36 patients who underwent elective surgeries were included in the study. The patients were included either in the group where no postoperative SIRS developed or in the group where postoperative SIRS did occur. In the seven-day period after the surgery, in 26 patients SIRS was found, and in 10 - sepsis was suspected (according to the ACCP/SCCM definitions). In patients who underwent abdominal surgeries blood concentration of C-reactive protein was determined prior to the surgery (measurement '0'), and then on postoperative days 1, 2, 3, 5 and 7.Results. The test for two variables (C-reactive protein on postoperative days five and seven) showed statistically significant difference, and for one variable (C-reactive protein on day three) - difference at the limit of significance. Thus, it was found that in the postoperative SIRS group the level of C-reactive protein is higher than in the non-SIRS group.Conclusions. Serial measurements of C-reactive protein are useful in the first week after surgery, as they can be prognostic of postoperative septic complications. Such complications can be anticipated if CRP on postoperative day 5 is higher than 1/2 of the maximum CRP concentration on day 2 or day 3, or CRP > 150 mg/L as of postoperative day 3. Unfortunately, the severity of the disease cannot be projected based on C-reactive protein level.

Opis:
In the paper, three different physico-chemical pretreatment methods in relation to bioethanol production were compared. The wood of fast-growing poplar species (Populus deltoides x maximowiczii and Populus trichocarpa Torr. & A. Gray ex Hook) and corn stover were used as a feedstock. The chemical composition and enzymatic hydrolysis efficiency of the biomass before and after pretreatments were compared. On the basis of the results, it was concluded that the applied pretreatments changed the chemical composition of the raw materials. In the case of the acid and LHW (liquid hot water pretreatment) methods, up to 93.7% of hemicelluloses (especially pentosans) were removed. From among the selected pretreatment methods, the LHW and alkaline methods occurred to be the most interesting. Nevertheless, from the bioethanol production point of view, the LHW process of Populus deltoides x maximowiczii wood was the best because after enzymatic hydrolysis, high amounts of glucose (up to 600.9 mg/g pretreated biomass) and minor amounts of xylose (up to 37.9 mg/g pretreated biomass) were produced. Moreover, based on the chemical composition and sugar profile analysis, it was proved that the Populus trichocarpa wood also has a high potential for bioethanol production.
