Abstract
Insulin hypoglycaemia was induced three times in 6 insulin-dependent, hypertensive diabetics: before instituting antihypertensive long-term treatment and after obtaining a satisfactory blood pressure with either alprenolol or metoprolol given in a randomized order. The blood glucose concentration (1.6-1.9 mmol/l) at which the hypoglycaemia necessitated intravenous administration of glucose was almost identical on all three occasions. During hypoglycaemia the systolic and diastolic blood pressures increased significantly by a mean maximal rise of 27/14 mmHg on alprenolol treatment, but remained unchanged on metoprolol. The responses of adrenaline, noradrenaline, cortisol, and growth hormone did not differ significantly on the three occasions. None of the beta-adrenergic drugs counteracted the early hormone defence mechanisms in hypoglycaemia and the signs of hypoglycaemia were not masked. The haemodynamic response was altered only by the non-selective (alprenolol) and not by the selective beta-adrenergic blocking agent (metoprolol).

Abstract
HLA disparity between hematopoietic stem cell (HSC) donor and recipient triggers T-cell and NK-cell allorecognition, and induces the GVHD, GVL effect and/or may cause an engraftment failure. This review will cover the scope of human genomic variation, the methods of HLA typing and interpretation of high-resolution HLA results. We describe the main subsets of related and unrelated HSC donors and outline the main aspects of HLA disparity and their effect on the outcome of the patients after allogeneic HSC transplantation (HSCT). The HLA match between HSCT donor and recipient is crucial, but for many patients a perfectly matched donor is not available. The HSCT from the alternative mismatched donor with one allele/antigen mismatch (9/10) can be as beneficial as a HSCT from a fully matched donor, especially in younger patients. For the remaining patients, the donors with permissive mismatches may be the option. The permissiveness depends not only on the potential adverse effect of the HLA mismatches, but also on the urgency of the transplantation, the desirable GVL effect and the potential efficacy of the alternative therapy available for the patient.

Abstract
Tissue Doppler imaging (TDI) can be useful in the evaluation of right ventricular (RV) regional dysfunction due to pulmonary diseases. The aim of the study was to assess RV dysfunction in patients with severe interstitial lung diseases (ILD), using both TDI and conventional transthoracic echocardiography (TTE). The study group consisted of 40 consecutive patients with end-stage ILD referred for lung transplantation (LT). Eighteen of them, mean age 47 +/-12 yr, who fulfilled the ATS/ERS criteria for LT (mean forced vital capacity (FVC) 1.4 +/-0.8 l, mean diffusing capacity for carbon dioxide (DLCO) <50% of predicted) constituted the active group, and 22 age-matched patients (mean age 49 +/-12 yr), who did not fulfill these criteria, were placed in the waiting group for LT. We found that among the TDI parameters, the longitudinal peak systolic strain rate (SR) measured at the RV outflow tract, was significantly more negative (-1.1 +/-0.3 vs. -3.2 +/-1.2 s(-1), P=0.03) and the time to peak velocity (TpVEL) in the medial and apical septal segments were shorter (129.9 +/-47.9 vs. 159.2 +/-38.1 ms, P=0.018 and 126.8 +/-44.3 vs. 154.6 +/-40.9 ms, P=0.019) in the patients from the active than those from the waiting group. TTE showed that patients from the active group had significantly lower values of tricuspid annulus plane systolic excursion (TAPSE) (14.3 +/-3.3 vs. 20.6 +/-6.2 mm, P=0.0003) and pulmonary artery acceleration time (PVAT) (70.3 +/-23.3 vs. 96.9 +/-12.4 ms, P=0.0001)compared with those from the waiting group. No other differences were found for other parameters of RV function between the examined groups. In conclusion, severity of lung disease in patients with ILD influences RV systolic dysfunction, which is reflected in both TDI and conventional echocardiographic parameters.

Abstract
BACKGROUND AND OBJECTIVE An association has been found between periodontal disease and the development of atherosclerosis. We investigated the hypothesis that periodontal disease triggers the expression of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) in blood. Increased levels of these parameters might then indicate early atherosclerosis. MATERIAL AND METHODS In this cross-sectional study, the material comprised 80 subjects with chronic periodontitis and 31 subjects with no periodontal disease. Sixteen years after diagnosis of periodontal disease ultrasonography revealed a statistically significant difference (p < 0.001) of carotid intima-media thickness between the subjects with chronic periodontitis and the periodontally healthy subjects. Matrix metalloproteinase-9 and TIMP-1 were analyzed from blood as periodontal and systemic inflammatory markers. The relationship between MMP-9, TIMP-1 and MMP-9/TIMP-1 as dependent variables and several independent variables (age, sex, smoking, education, body mass index, hypertension, periodontal disease and cholesterol) were analyzed in multiple logistic regression models to assess the value of the inflammatory markers in predicting carotid atherosclerosis. RESULTS Matrix metalloproteinase-9 and TIMP-1 were significantly higher in plasma from subjects with periodontal disease and atherosclerosis. Periodontal disease was identified as the principal independent predictor both for atherosclerosis (odds ratio 3.89 for increase in bilateral carotid intima-media thickness) and for increased MMP-9, TIMP-1 and MMP-9/TIMP-1 (odds ratio 2.58, 5.53 and 3.41, respectively). Classical atherosclerosis risk factors, such as increased total cholesterol, age and sex (women), were significant predictors in the model. CONCLUSION Matrix metalloproteinase-9, TIMP-1 and MMP-9/TIMP-1 in blood from subjects with periodontal disease could be useful laboratory markers for increased carotid artery intima-media thickness.

Abstract
INTRODUCTION Chronic infection and inflammation are considered to be risk factors in the development of cardiovascular diseases; the chronic inflammatory and microbial burden caused by the dental plaque in these individuals may predispose them to atherosclerotic process. AIMS The aims were to study the involvement of a high level of dental plaque, severe gingival inflammation and periodontitis in the development of early atherosclerotic process in women. METHODS Forty-six randomly chosen women with periodontitis and 21 periodontally healthy women were subjected to a comprehensive clinical oral examination, including oral hygiene status and level of gingival inflammation. Atherosclerotic risk factor analysis and carotid ultrasonography were performed. Common carotid artery intima-media thickness (IMT) and lumen diameter were measured and intima-media area (cIMA) was calculated. The following statistical methods were used: analysis of variance, chi-squared tests and multiple logistic regression analysis. RESULTS There were highly significant differences between the patients and controls in the amount of dental plaque, gingival inflammation as well as bleeding on probing and pocket depth. The mean values of IMT and cIMA were significantly higher in women with periodontal disease than in controls. Multiple logistic regression analysis identified periodontitis as a principal-independent predictor of both the common carotid artery cIMA and IMT. CONCLUSIONS The present results indicate that a high amount of dental plaque, severe gingival inflammation as well as periodontitis seem to be associated with the development of atherosclerotic lesions in women already at its early and subclinical stages.

Abstract
The objective of this study was to determine the prevalence of left ventricular (LV) dysfunction in patients with advanced interstitial lung disease (ILD) and the relationship between LV function and factors limiting physical activity. In 2005-2006, 40 patients with end stage ILD were admitted with qualifications for lung transplantation (LT). From this group, 18 patients (7 women, 11 men) were referred for LT (active list), 22 patients (8 women, 14 men), who did not meet the ATS/ERS criteria for LT were excluded from this procedure (waiting list). All patients had echocardiography, spirometry, 6-min walking test (6MW), and gas exchange measurements. The following main echocariographic data that describe the LV function and morphology were taken into account: LVs, LVd, LVPWd, LVPWs, Ao, LA, ESV, EDV, and EF. We noted significant differences in LVPWd (P=0.01), ESV (P=0.01), and EDV (P=0.02), which presented lower values in patients on the active list compared with those on the waiting list. A positive correlation was found between 6MW and LVs (r=0.41), LA (r=0.45), ESV (r=0.62), and EDV (r=0.68). Correlations between spirometric, gas exchange, and left ventricle echocardiographic data were also observed. We conclude that patients on active list for lung transplantation present a decrease in the diameter and volume of the left ventricle. The latter change may influence the functional ability of interstitial lung disease patients.

Abstract
In the previous studies, some human major histocompatibility complex (MHC) genes such as TNF, LTA and human leukocyte antigen (HLA)-DR2 genes and A1-B8-TNF(-308A) haplotype were implied in non-Hodgkin's lymphoma (NHL) outcome. In the current study, we have assigned most probable six-locus haplotypes determined by HLA-A, -Cw, -B and -DRB1 highly polymorphic genes and non-HLA LTA(+252) and TNF(-308) single nucleotide polymorphisms (SNPs) in 152 NHL Caucasian French patients. We have broadly mapped the MHC region by its component blocks and tagging alleles. Ten frequent (with haplotype frequency >1%) six-locus extended haplotypes (EHs) were revealed in NHL patients. The only two adjacent locus fragment of 8.1 EH associated with shortened freedom from progression (FFP) was B*08-LTA(+252G) (P= 0.0084, RR = 2.45). Interestingly, 305-kbp-long, four-locus fragment of 8.1 EH, Cw*07-B*08-LTA(+252G)-TNF(-308A) block was much strongly associated with shortened FFP (P= 0.00045, RR = 3.26). The analysis of further extended haploblocks comprising five or six loci showed weaker association with outcome measures, suggesting linkage disequilibrium to be the cause of DRB1*03 and A*01 allele associations. In contrast, all fragments of 7.1 EH influenced FFP favorably with top association of TNF(-308G) allele. In multivariate analysis, only Cw*07-B*08-LTA(+252G)-TNF(-308A) and TNF(-308G)-DRB1*01 haplotypes remained predictive for shortened FFP (P= 0.024 and 0.027, respectively) and independent of International Prognostic Index (P= 0.00044). This study reveals that the block composition of EHs may cause important functional differences for NHL outcomes. Further study will be required in NHL patients by fine mapping with dense microsatellite or SNP tags to define susceptibility genes in associating regions.

Abstract
Adsorption of the three carbohydrates sucrose, glucose and fructose from aqueous solutions was investigated on an ion-exchange resin. The adsorption equilibrium of single components, binary and ternary mixtures was quantified by frontal analysis and the adsorption-desorption method. The experiments covered a concentration range up to 600 g/L at 60 degrees C and 80 degrees C. Within this range the adsorption isotherms of carbohydrates exhibited anti-Langmuirian behavior. Data of mixture adsorption revealed reversed competitive (synergistic or cooperative) effects, i.e., an increase of the concentration of one component of the mixture enhanced the adsorption of others. To model such an adsorption behavior the anti-Langmuir model has been used. The isotherm parameters determined for single components were used to simulate the competitive adsorption equilibria through the IAS (ideal adsorbed solution) theory. Finally, dynamic concentration profiles of multicomponent mixtures have been recorded. The shapes of adsorption and desorption curves confirmed the observed competitive effects found in the equilibrium studies. The breakthrough curves measured were simulated using the equilibrium theory as well as a numerical solution of the equilibrium dispersive model.

Abstract
Among all the fossils, petrified wood belongs to the most impressive and most common of materials. Still, its study has not exceeded the purely phenomenological level. The recognition of the conserved structure of petrified wood seems to be of meaning for understanding the geological past, the complete carbon cycle inside the Earth, and the structure of potential new materials. The first ever published spatial distributions of the remains of the primordial organic material (lignin, cellulose, pectins) in the cells of permineralized wood, from Dunarobba (Central Italy), are presented here. They were collected using micro-Raman spectrometry. The composite nature of the petrified material (calcite located in the lumena of cells and goethite located in the cell walls) was confirmed by electron, proton, and X-ray microprobes. The structure of the cell walls was well preserved. The mineralization process was induced by the tracheidal water flow and was stopped after formation of pipe-like goethite shielding of the cell walls on the cellulose scaffolds. The chemical (Eh and pH ranges) and probable microbial conditions for such a pattern of mineralization were determined. We estimate that substantial amounts of the primordial organic matter were preserved in bodies of petrified wood on a global scale. The wood petrifaction process, if well understood, can be a basis for the production of "everlasting" organic-inorganic composite compounds.

Abstract
BACKGROUND AND AIM The role of leucocyte antibodies in donors is poorly understood in pathogenesis of transfusion-related acute lung injury (TRALI). We examined antibodies in donors and traced recipients transfused with their blood components. MATERIAL AND METHODS Antibodies were examined in 1043 donors by five methods, look back performed in 26 recipients. RESULTS Anti-human leucocyte antigen detected by enzyme-linked immunosorbent assay in 9.8% women but none in men. Specificities identified using FlowPRA, antibodies detected after several months. TRALI reported in one recipient from immunized donor. In 11 of 26 recipients without TRALI, cognate antigens were identified. CONCLUSION Detection of antibodies in donors cannot predict TRALI, even in recipients with cognate antigen(s).

Abstract
In the present study, we addressed the question of how often HLA-DRB1-matched donors can be found by further typing of AB-matched donors and whether Cw preselection can be helpful. Sixty-eight patients and 174 donors were enrolled in the study. In all donors, confirmatory DNA Cw typing was performed to check reliability of registry Cw data. Among the 129 Cw serologically typed donors, 11 (8.5%) were not confirmed by DNA typing and for 77 (60%) at least one Cw blank antigen was genetically confirmed. In healthy controls, haplotype frequency higher than 1% has been found for 21 (55%) out of 38 Cw-DRB1 haplotypes observed. A subtotal delta made up 67% of subtotal haplotype frequency fraction of 21 haplotypes confirming strong linkage disequilibrium of Cw-DRB1 loci. After Cw preselection 12 (15.4%) out of 78 donors were matched in both DRB1. On the other hand, only two (2.1%) out of 96 AB-matched donors with unknown or incompatible Cw were matched in both DRB1 at low-resolution level (OR = 8.55; P = 0.0060; 95%CI 1.85-39.5). We found at least one DRB1-matched donor for 12 (26.1%) out of 46 patients with Cw-matched donors for which 1-5 (median = 1) of Cw-preselected donors were chosen for further typing. Cw preselection of HLA AB-matched donors for further DRB1 typing may improve the efficacy of stem cell donor search process.

Abstract
The aim of the study was to identify prognostic factors that would differentiate patients with interstitial lung disease between those with and without a chance to survive until lung transplantation. A retrospective study was performed in patients with interstitial lung disease referred for lung transplantation between September 1999 and April 2005. The analysis included the demographic data, the time from referral to transplantation, the functional tests (FVC, FEV1, FEV1%VC, the PaO(2) at rest and after oxygen supplementation via a nasal catheter), the count of NYHA functional classes, the left ventricular ejection fraction (EF), the distance covered during a 6-min walk test, and the pathogens in the respiratory tract. The patients were divided into two groups: Group 1 - lung transplant candidates who survived until the successful procedure and Group 2 - lung transplant candidates who died while on the waiting list. There were statistical differences between the two groups in PaO2 after supplementation (P=0.005), EF (P=0.002), and the 6-min walk distance (P=0.001). It appears that simple functional tests of the cardiorespiratory system may define survival of patients with interstitial lung disease waiting for lung transplantation.

Abstract
A Gram-negative, non-sporulating, rod-shaped, motile bacterium, with a single polar flagellum, designated strain PsJNT, was isolated from surface-sterilized onion roots. This isolate proved to be a highly effective plant-beneficial bacterium, and was able to establish rhizosphere and endophytic populations associated with various plants. Seven related strains were recovered from Dutch soils. Based on 16S rRNA gene sequence data, strain PsJNT and the Dutch strains were identified as representing a member of the genus Burkholderia, as they were closely related to Burkholderia fungorum (98·7 %) and Burkholderia phenazinium (98·5 %). Analysis of whole-cell protein profiles and DNA–DNA hybridization experiments confirmed that all eight strains belonged to a single species. Strain PsJNT had a DNA G+C content of 61·0 mol%. Only low levels of DNA–DNA hybridization to closely related species were found. Qualitative and quantitative differences in fatty acid composition between strain PsJNT and closely related species were identified. The predominant fatty acids in strain PsJNT were 16 : 0, 18 : 1ω7c and summed feature 3 (comprising 16 : 1ω7c and/or iso-15 : 0 2-OH). Isolate PsJNT showed high 1-aminocyclopropane-1-carboxylate deaminase activity and is therefore able to lower the ethylene level in a developing or stressed plant. Production of the quorum-sensing signal compound 3-hydroxy-C8-homoserine lactone was detected. Based on the results of this polyphasic taxonomic study, strain PsJNT and the seven Dutch isolates are considered to represent a single, novel species, for which the name Burkholderia phytofirmans sp. nov. is proposed. The type strain is strain PsJNT (=LMG 22146T=CCUG 49060T).
