Abstract
BACKGROUND CYP3A5 enzyme encoded by CYP3A5 is important for drug metabolism in gut and liver, whereas P-glycoprotein by ABCB1, is an ATP-dependent drug efflux pump which exports endo- and exogenous substances outside the cell. Aim: The study was to assess the prevalence of CYP3A5 alleles: *1, *2, *3, *4, *6 and *7, and C and T of ABCB1 in Poles, Belarusians and Bosnians and to compare it with the data reported from other European populations. Subjects and methods: Overall, 511 unrelated healthy subjects from Poland (n = 239), Belarus (n = 104) and Bosnia and Herzegovina (n = 168) were included in this study. Allele frequencies and statistical parameters (AMOVA version 2.9.3) were determined. Results: In Poles, Belarusians and Bosnians the *3 allele of CYP3A5 was the most common, and wild-type allele *1, were: 5.8%, 1.6% and 2.1%, respectively. Allele *2 was very rare, and alleles *4, *6 and *7 were not detected. For the populations mentioned above, the ABCB1 allele C was: 48.1%, 51.4%, 52.4%, respectively. CONCLUSION In compared populations, the distribution of CYP3A5 variants but not ABCB1, differed significantly. Alleles *4, *6 and *7 of CYP3A5 did not occur or occurred rarely.

Abstract
Background:There is some evidence that neuropsychiatric changes occur in systemic lupus(1) and rheumatoid arthritis(2). However, little is known regarding a possible disease-related impairment of cognitive abilities in axial spondyloarthritis (axSpA).Objectives:To evaluate patients with axSpA regarding cognitive impairments.Methods:Patients with axSpA attending two rheumatology practices were routinely evaluated by rheumatologists and underwent a computer-based memory and attention test (MAT) (3, 4) with subscale scores ranging from 0 (worst) to 15 (best). The results of short-term memory and working memory were compared to an age-, sex- and education-matched control group of healthy subjects. Descriptive results are presented as median (IQR) for interval data and n (%) for nominal data if not stated otherwise. Two-tailed Wilcoxon signed-rank tests including Bonferroni-Holm adjustment for multiple tests were conducted to investigate the magnitude of potential differences in cognitive abilities.Results:101 consecutive patients were tested (Table 1). After multiple testing adjustment for two subscales, Wilcoxon signed-rank tests returned significant findings for working memory (V = 539.5, p = 0.006, |r| = 0.204) but not for short-term memory (V = 1075, p = 0.351, |r| = 0.078). Regarding the scales’ anchors, descriptive results on pairwise differences suggested axSpA patients to have working memory scores that are on average 10.7% lower compared to control participants (mean Δ= -1.64, SD Δ= 5.95).Table 1.Patients and disease characteristicsn%MeanSDMedian25% Quantile75% QuantileAge10110051.111.6524260Age (female)4847.552.611.75444.561Age (male)5352.549.811.5514157< 13 years formal education4746.5≥ 13 years formal education5453.5HLA B27 positive n/N64/9263.4Disease duration (years)10110013.711.712421Disease duration (female, years)4847.511.69.99417.2Disease duration (male, years)5352.515.512.915523BASDAI9291.13.71.73.82.45BASFI9190.132.42.31.24.5BASMI7574.31.92.3103ASDAS98972.30.82.31.82.8Conclusion:The MAT computerized testing is a feasible test and was well accepted by patients.

Abstract
Previous research suggested that several genetic polymorphisms are associated with increased risk of ischaemic stroke (IS) in young adults. However, the predictive biomarkers of IS in young adults are still unclear. Our aim was to assess the contribution of modifiable and genetic factors in IS in young adults. In total, 40 stroke patients and 40 healthy controls aged 20 to 50 years were recruited. Data on modifiable factors were collected, then participants were genotyped for seven SNPs linked to thrombophilia: ACE rs1799752, PAI-1 rs1799889, APOE rs1412 and rs429358, FV rs6025 and rs1800595, and FII rs62623459. Significantly increased risk factors: hypertension and dyslipidaemia in stroke patients compared with the controls: 50.0 % vs 27.5 % and 75.0 % vs 40.0% (P = 0.039 and P = 0.002, respectively) were observed. Stroke patients compared with controls did not differ in distribution of ACE, APOE, FV, and FII variants. The 4G4G homozygotes of the PAI-1 gene were significantly more prevalent in stroke patients compared to the controls: 42.5 % vs 17.5 %, (P = 0.033). In the group with the small vessel occlusion subtype of stroke, statistically significant overrepresentation of 4G4G homozygotes and frequency of the 4G allele compared with controls: 57.1 % vs 17.5 % and 0.7 vs 0.45 (P = 0.026 and P = 0.03, respectively) were observed. Independent predictors of stroke incident were: dyslipidaemia (OR (95% CI) = 4.2 (1.4-12.4)) and 4G4G genotype (OR (95% CI) = 3.9 (1.1-13.7)). These results confirm the contribution of dyslipidaemia and 4G4G genotype in the increased risk of IS in young Bosnian adults.

Abstract
Background: The 17q21.31 band is one of the most structurally complex and evolutionarily dynamic region of the genome. Frequencies of two SNPs: rs9468 and rs1800547 determine worldwide distribution of H1 and H2 haplotypes. Recent studies have demonstrated that H2 haplotype is ancestral in hominoids and under positive selection in European populations. The role of non-inverted orientation (H1 haplotype) and inverted orientation (H2) remains unclear, i.a. it is suggested that mothers who are H1H2 heterozygotes, tend to have more children than H2H2 homozygotes on average. Materials and methods: We investigated the prevalence of haplotypes of the 17q21 inversion in 154 women with pregnancy loss and 154 mothers with at last one live-born child, mean age: 33.0 (±5.4) y/o and 31.4 (±6.7) y/o, respectively. Following DNA extraction from buccal swabs, the genotyping was performed. All tests were performed using the R CRAN statistical software. Haplotypes were compared between groups. Results: In women with and without pregnancy loss we identified: 74.7% and 79.2% H1H1, 24.0% and 17.5% H1H2 and 1.3% and 3.3% H2H2 of haplotypes, respectively. There were no significant differences between the distributions of haplotypes in women with and without pregnancy loss. Statistically significant difference between the average number of children in women with H1H2 haplotype (navg. = 1.54) compared to women with H2H2 haplotype (navg. = 1.29), was not found. Conclusion: Haplotype H2 of the 17q21.31 inversion was not linked to pregnancy loss and number of children in Bosnian women.

Abstract
Due to inconsistent results of APOE variants in the survival of pregnancy we investigated the potential relationship of APOE rs7412 and rs429358 with pregnancy loss (PL) in Bosnian women. We enrolled 154 women with PL. The minimum week of miscarriage was 6, while the maximum was 28. As a control group, an equal number of mothers with at least one live-born child was included. All women were recruited from the Institution of Health Protection of Women and Motherhood in Sarajevo, Bosnia and Herzegovina. Genotyping was performed by real- time PCR at the Department of General Pharmacology and Pharmacoeconomics, Pomeranian Medical University. The prevalence of genotypes E2/E3, E2/E4, E3/E3, E3/E4, E4/E4 in the group with and without PL were: 14.3 %, 1.3 %, 70.8 %, 12.3 %, 1.3 %, and 13.6 %, 1.3 %, 70.1 %, 14.3 %, 0.7 %, respectively. The frequency of the E4/E4 genotype in women with 1-2 and 3-4 PL compared to women without PL did not differ significantly between those three groups (P value = 0.0712). The frequencies of alleles ԑ2, ԑ3, ԑ4 in the group with and without PL were: 6.8 %, 85.1 %, 8.1 % and 7.5 %, 84.1 %, 8.4 %, respectively, and did not differ significantly. We conclude that our study does not confirm rs7412 and rs429358 as a potential risk factor for PL in the studied group. To elucidate the relationship between PL and variants of the APOE gene, studies with a larger sample size and placental histomorphology and genetic diagnosis are required.

Abstract
Introduction Several analysis for different population conclude that endothelial plasminogen activator inhibitor 1 gene polymorphism, -675 ID, 4G/5G PAI-1 (ref SNP ID: rs1799889, also described as rs34857375, has merged into rs1799762) may increase risk of pregnancy loss (PL). However, there is a disagreement as to the association 4G allele with pregnancy loss. Aim Therefore, we decided to investigate the -675 ID, 4G/5G PAI-1 as a potential genetic factor linked to PL in European and worldwide populations. A systematic review of the scientific literature was conducted with the use of the PubMed and Scopus electronic databases (1991-present), using the following search terms: pregnancy loss, miscarriage, genetic risk of thrombophilia, rs1799889 PAI-1 gen, 4G/5G PAI-1 gene polymorphism, PAI-1 gene locus 4G/5G polymorphism. Results Among European populations, the statistically significant association between 4G allele and recurrent PL only in Czechs and Bulgarian women was found (p<0.002 and p=0.018, respectively); while, among populations outside Europe in Iranian, Tunisian and Turkish women (each p<0.001). Conclusions We concluded, that both in Europe and elsewhere in the world, the high frequency of 4G allele in population, is not unambiguously linked with the risk of pregnancy loss.

Abstract
The aim of this study was to examine the association of single-nucleotide polymorphisms (SNPs) in the gene encoding ficolin-2 protein (FCN2 gene) at positions -986 (rs17514136), -602 (rs3124953), and -4 (rs3124952) with dental caries in Polish children. Two hundred and sixty Polish Caucasian children aged 15 years were enrolled in this study: 82 with "higher" caries experience (DMFT >5) and 178 with "lower" caries experience (DMFT ≤5). In addition, subjects with caries experience (DMFT ≥1) and caries-free subjects (DMFT = 0) were compared. FCN2 SNPs were genotyped with PCR-RFLP methods. There were no significant differences in the genotype, allele, or haplotype distributions in 3 analyzed SNPs of the FCN2 gene between children with "higher" and those with "lower" caries experience as well as between children with caries experience and caries-free children. In conclusion, we did not find any association of FCN2 promoter polymorphisms at positions -986, -602, and -4 with dental caries in Polish children.

Abstract
OBJECTIVES The human growth hormone receptor (GHR) exon 3 deletion (d3) polymorphism has been reported to be associated with the responsiveness to growth hormone (GH) therapy. This study aimed to: (a) assess the frequency of this polymorphism in a group of Polish children with idiopathic growth hormone deficiency (IGHD) and (b) analyze their response to GH therapy. METHODS The study group consisted of 67 prepubertal children with IGHD. The control group was composed of 150 Caucasian newborns from whom umbilical cord blood samples were drawn. A genotype analysis was performed using the PCR multiplex technique in search for the existence or deletion of exon 3 of the GHR gene. RESULTS In the study group the following genotype distribution was observed: fl/fl-GHR 64.2%; fl/d3-GHR 29.9%; d3/d3-GHR 5.9%. The total percentage of patients with d3-GHR polymorphism was 35.8% and 64.2% patients had a fl/fl-GHR. No significant differences were noted in growth rate SD before introducing therapy and growth rate after one year of recombinant human GH therapy in patients with individual genotypes. In the control group the genotype distribution was: fl/fl-GHR 63.3%; fl/d3-GHR 29.9%; d3/d3-GHR 6.8%. CONCLUSION No differences were observed in genotype distribution between the study and the control group. Patients with IGHD did not differ among each other depending on their genotype (fl/fl-GHR or fl/d3-GHR) in terms of growth velocity before introducing therapy or growth rate after one year of recombinant human GH therapy.

Abstract
OBJECTIVE Etiology of Autism Spectrum Disorders (ASD) is insufficiently known. It is suggested that genes play a crucial role in ASD but additional environmental factors to exacerbate the syndrome are needed. Recently, the inflammatory factors in ASD that may predispose to the disorder attract a great attention. Therefore, the aim of this article was to review the literature on the possible association of the immune system malfunctions with the risk of developing ASD. MATERIALS AND METHODS Available articles from PubMed and Google Scholar were analyzed using time descriptors: 1996-2015 and key words: autism spectrum disorder, cytokines and immune system. RESULTS Individuals with ASD demonstrate aberrant immune response in central nervous system, peripheral blood and gastrointestinal tract. CONCLUSIONS Immune malfunctions may play a role in developing ASD.

Abstract
Data on prevalence and phenotypic consequences of nucleotide-binding oligomerisation domain 2/caspase recruitment domains 15 (NOD2/CARD15) variants in Crohn's disease (CD) population in Poland and Bosnia and Herzegovina (B&H) are nonexistent. We aimed to determine the prevalence of NOD2/CARD15 mutations and their association with disease phenotype in Polish and Bosnian patients with CD and in healthy controls. We prospectively recruited 86 CD patients and 83 controls in Poland and 30 CD patients and 30 controls in B&H, 229 in total. We determined the prevalence of NOD2/CARD15 mutations and their association with the disease phenotype according to Montreal classification. Participants were genotyped for Leu1007fsinsC and Gly908Arg mutations. At least one CD-associated allele was found in 29/86 (33.7%) of Polish CD patients and in 9/83 (10.8%) of healthy controls (p<0.001). In both CD patients and controls in Bosnian sample, at least one NOD2 mutation was found in equal number of patients (3/30; 10%) with all of the NOD2 mutation positive CD patients being homozygous, while controls being heterozygous. In Polish sample, perianal disease was less frequent in CD patients with any NOD2 mutation (1/21; 4.8%) compared to those without (11/41; 26.8%; p=0.046). Higher percentage of patients with NOD2 mutations had history of CD related surgery when compared with those without mutations (66.7% vs. 43.3%; p=0.05). The risk for CD is increased in patients with NOD2 mutations (Poland) and especially in the presence of homozygous NOD2 mutations (Poland and Bosnia). The presence of variant NOD2 alleles is associated with increased need for surgery and reduced occurrence of perianal disease.

Abstract
The endocrine activity of the thyroid gland is accomplished by its follicular and parafollicular cells. In these cells, numerous G proteins-dependent pathways are active and potentially could be regulated by a 33-kDa cytoplasmic protein phosducin, which interacts with the Gβ subunit and may compete with Gα or Gβγ dimer effectors. Significant expression of phosducin has been shown in the retina, pineal gland, and some neurons. Here, we studied postoperative thyroid tissue samples collected from patients with nodular goiter and 2 thyroid-derived cell lines for the presence of phosducin. Using reverse transcription PCR with product sequencing and highly sensitive immunodetection we identified phosducin mRNA and protein in the thyroid gland and parafollicular C TT cells, but not in the follicular Nthy-ori 3-1 cell line. We also observed that siRNA-mediated silencing of phosducin gene expression decreased Ca(2+)-stimulated secretion of calcitonin and serotonin by TT cells.

Abstract
Introduction: Early menopause may be associated with serious health risks resulting from, for example, decreased oestrogen levels. This may occur despite hormone replacement therapy. Aim: The aim of this study was the determination of the effect of selected reproductive factors and smoking on age at the onset of menopause in women from Szczecin and surrounding areas. Material and Methods: 305 women after natural menopause were asked to complete a questionnaire, and blood samples were collected from them to test for the levels of follicle stimulating hormone (FSH) and oestradiol (E2). Results: Smoking women experienced menopause on average more than a year earlier than non-smokers, but this difference was not statistically significant. There was no statistically significant effect of age at menarche or first birth on age at the last menstrual period. Conclusions: Age at menarche and first birth were not related to age at menopause. In smoking women, menopause occurred earlier but the difference was not statistically significant.

Abstract
BACKGROUND Rivastigmine is the only cholinesterase inhibitor (ChEI) available as transdermal patch. The patch was developed to improve gastrointestinal tolerability and treatment adherence to higher dosages as compared with oral medication. Preferences of patients and caregivers for the patch were reported; however, neither patient compliance nor caregiver burden has yet been measured under routine practice conditions. METHODS This was a prospective, multi-centre, observational study in patients with Alzheimer's disease treated with rivastigmine patch in Germany. To compare the transdermal with oral dosage forms, physicians were asked to enrol patients who recently switched from oral to transdermal medication. Beyond effectiveness and tolerability, outcome measures were drug adherence evaluated by the Morisky questionnaire, and caregiver burden, measured as the daily time expenditure for dressing the patient, controlling appearance and administration of medication. RESULTS In total, 1104 outpatients (57.5% female gender; mean age 77 ± 7 years) were enrolled in 220 sites. After 6 months of treatment, 67.5% of patients had an improved Clinical Global Impression and the Mini-Mental State Examination score increased from 19.0 ± 5.1 to 20.0 ± 5.2 (p < 0.001); 84.1% of patients were still on treatment, 64.6% on the target dose of 9.5 mg/day. Compliance and patient satisfaction with therapy continuously increased over the study period and average time savings of caregivers added up to 20 min/day. In general, tolerability was deemed good and there were no unexpected adverse events. CONCLUSIONS Transdermal rivastigmine is an effective treatment alternative, which may improve adherence and treatment satisfaction of the patient and relieve the caregiver. Controlled parallel-group trials are warranted. CLINICAL TRIALS REGISTRATION none (observational study).

Abstract
OBJECTIVE Cyclic adenosine monophosphate/protein kinase A (PKA) is important in embryonic development. The human AKAP10 gene is polymorphic: 1936A>G results in changes to a PKA-binding domain and increased targeting to mitochondria. Previous studies found G1936 as 'deleterious' in adults, and this study investigates whether this holds true in preterm birth. STUDY DESIGN Study group consisted of 80 preterm newborns (PTNs) born before the 38th gestation week. Control group consisted of 123 full-term healthy newborns born after the 37th gestation week with uncomplicated pregnancies. Genomic DNA was extracted from umbilical blood and AKAP10 genotypes were identified by PCR/restriction enzyme. RESULT Significant differences in frequencies of 1936A>G genotypes/alleles between both groups were found. PTNs had increased frequency (55%) of AA homozygotes (odds ratio, AA versus AG+GG: 2.63 (95% confidence interval: 1.33 to 5.20), P=0.006) after adjustments: mothers with previous PTNs, smoking, first pregnancy, first delivery and Cesarean section. CONCLUSION Results suggest G1936 is preventative factor against preterm birth, in contrast with previously asserted negative effects in adults.

Abstract
BACKGROUND Ischemia/reperfusion injury in organ transplantation is a multifactor process that may lead to delayed graft function (DGF), and has a significant impact on short- and long-term graft survival. The activation of the renin-angiotensin system may be important in the pathophysiology of DGF. Preservation solutions are thought to diminish the ischemic injury, and appropriate choice of the solution should contribute to improved graft function and better prognosis for graft survival. The aim of this study was to examine the effect of preservation solutions UW and EC on the expression of renin I, angiotensinogen and angiotensin I-converting enzyme genes in rat kidney. MATERIAL/METHODS The study was carried out on Wistar rat kidneys divided into 3 groups: kidneys perfused with 0.9% NaCl (control group), with UW preservation solution, and with EC preservation solution. We investigated the expressions of renin I, angiotensinogen- and angiotensin I-converting enzyme genes in kidneys perfused with EC and UW solutions after 12 min (minutes) and 24 h (hours) of cold ischemia and 30 min of warm ischemia. RESULTS The perfusion with UW and EC solution caused an increase of renin I, angiotensinogen and angiotensin I-converting enzyme genes expression in kidneys. This increase was enhanced in kidneys perfused with UW solution in comparison with kidneys perfused with EC solution. The 24 h preservation with UW solution resulted in a decrease of renin-angiotensin activity increased in cold ischemia. CONCLUSIONS UW preservation of 24 h decreased renin-angiotensin system activity activated in cold ischemia but not in warm ischemia.

Abstract
OBJECTIVE The aim of the study was to examine whether the MBL2 C(-290)G and G161A, MASP2 A359G, AMELX C287T and C522T, and ENAM C2452T polymorphisms are associated with dental caries. SUBJECTS AND METHODS Genomic DNA of 95 Polish children with 'higher caries experience' (HC) and 84 subjects with 'lower caries experience' (LC) belonging to two age-groups (5 and 13 years old) was extracted from the buccal mucosa. SNPs were genotyped with PCR-RFLP methods. RESULTS Among 5-year-old children, we found significantly higher percentage of subjects carrying MBL2 (-290)G allele in HC group compared with LC group (43.2%vs 17.6%, P = 0.023). MBL2 C(-290)G-G161A C-G haplotype was overrepresented in LC group in 5-year-olds (P = 0.01), while the opposite association was observed in 13-year-olds, where C-G was overrepresented in HC group (P = 0.028). In 5-year-old children, the frequency of MBL2 G-G haplotype was higher in HC group compared with LC subjects (P = 0.045), while the opposite association (with borderline significance) was observed in 13-year-old children (P = 0.057). SNPs in MASP2, AMELX, and ENAM were not associated with dental caries. CONCLUSION MBL2 gene polymorphism is associated with caries experience in Polish children, but the direction of this association seems to be opposite in primary and permanent dentition.

Abstract
AIM To compare A allele frequencies of the 845G>A mutation of 10 Slavic populations in central, eastern, and southern Europe between each other and with other European populations. METHODS The 845G>A mutation from the DNA of 400 Polish neonates collected in 2005-2006 was analyzed by polymerase chain reaction-restriction fragment length polymorphism. The data were compared with reports from other countries. RESULTS We identified 381 GG homozygotes, 18 GA heterozygotes, and 1 AA homozygote. The 845A allele frequency was 2.5%, which makes the summary figure for Poland from this and previous studies 3.5%. The average prevalence for Poland and other West Slavic countries was 3.6%, similar to Russia (inhabited by the East Slavs, 3.5%). The average prevalence in South Slavic countries was 2.2%, gradually decreasing from 3.6% in Slovenia to 0% in Bulgaria, with a longitudinal linear gradient (adjusted R(2)=0.976, P<0.001). CONCLUSIONS The West and East Slavs, together with Finland, Estonia, Germany, Austria, Hungary, Slovenia, and Croatia, form a group with 845A allele frequencies between 3% and 4%. In the South Slavs, there is a gradual decline in the prevalence of 845A allele from northwest to southeast, with a surprisingly exact east-west linear gradient.

Abstract
The problem of shortage of physicians has been discussed controversially in Germany for years, and the different positions of the interest groups involved have not been resolved. The question of the present and anticipated future requirement of physicians is central for an appropriate and necessary medical care of the population. In the analysis, supply and demand of medical care have to be distinguished. Relatively reliable data do exist for the supply of physicians; however, the changing number of working hours that male and--in particular female--physicians are willing to contribute should be taken into consideration. Reliable data for the future demand are presently not available. Several variables (e.g., demography, disease spectrum of an aging society, medical progress, the changing rules of working hours, and the shift of medical care between hospital and practice care) depend on future developments. Considering the existing serious indicators of a growing shortage of physicians, it is recommended to put more effort into the scientific investigation of these factors. More profound data should improve the basis for decisions in health and education politics.

Abstract
OBJECTIVES To assess the effectiveness and safety of zoledronate (ZOL) in preventing glucocorticoid therapy-associated bone loss in patients with acute flare of Crohn's disease (CD) in a randomized, double-blind, placebo-controlled trial. METHODS Forty CD patients starting a glucocorticoid therapy (60 mg prednisolone per day) for acute flare (CD activity index (CDAI) >220) were randomized to compare the effect of ZOL (4 mg intravenous, n=20) or placebo (n=20) on change in lumbar bone mineral density (BMD). All patients received calcium citrate (800 mg) and colecalciferol (1,000 IU) daily. Dual energy X-ray absorptiometry (DXA) of the lumbar spine (L1-L4) was performed at baseline and day 90. Follow-up examinations at day 1/7/14/30 and 90 included laboratory tests and adverse event/serious adverse events reports. RESULTS Thirty-six patients were available for per-protocol analysis. With placebo (n=18), a decrease in BMD was seen (T-score: -0.98 ± 0.8, day 0 and -1.25 ± 0.77, day 90, P=0.06), with ZOL (n=18) BMD increased (-1.15 ± 1.02, day 0 and -0.74 ± 1.09, day 90, P=0.03). The change in BMD under placebo (-0.26 ± 0.21) vs. ZOL (+0.41 ± 0.19) was highly significant (P=0.006). In all, 14 out of 18 patients with ZOL had an increase in BMD (+0.64 ± 0.48), 12 of 18 with placebo a decrease (-0.50 ± 0.39). Changes of clinical findings and laboratory results of inflammation (leukocytes, platelets, and C-reactive protein) were the same in- and between-groups throughout the study. With ZOL, serum bone degradation marker β-Cross-Laps decreased. Study medication was safe and well tolerated. CONCLUSIONS ZOL is effective in preventing glucocorticoid therapy-induced bone loss in patients with acute flare of CD and should be considered whenever a glucocorticoid therapy is started in CD patients.

Abstract
Factor V Leiden (G1691A FV mutation) is a widely acknowledged risk factor of deep vein thrombosis, including pulmonary embolism as the most serious complication. However, its high prevalence of ~5%in the Caucasian population might be related to an unknown evolutionary advantage. It might exert a beneficial effect on the carrier, e.g. protecting women from excessive bleeding during labour or allowing increased survival in severe sepsis or with other inflammatory diseases. The aim of our study was to verify or contradict the hypothesis of a favourable association between the A allele (A1691) and longevity in the Polish population. For this purpose, the G1691A mutation was analyzed by PCR-RFLP in 1016 Poles: 400 neonates (187 female and 312 male), 184 healthy adults (129 female and 55 male), and 432 long-lived individuals (age ≥95 years: 343 women and 89 men). Frequencies of G1691A carriers and the A1691 allele in long-lived individuals (0.2% and 0.1%, respectively) were significantly lower than in neonates (4.2% and 2.2%, respectively) and adults (3.3% and 1.6%). The frequency of the G1691A factor V Leiden mutation decreased with age, which indicates a shorter survival time among A1691 allele carriers in the Polish population.

Abstract
BACKGROUND AND OBJECTIVE It was the aim of this study to compare the sensitivity and specificity of low-dose CT colonography (CTC) with that of optical colonoscopy (OC) in asymptomatic patients undergoing these tests in a screening program for colonic cancer. PATIENTS AND METHODS 58 patients (mean age 62.6 years) were included. They underwent low dose CTC and, immediately afterwards, colonoscopy. The colonoscopists were unaware of the CTC findings. A "second look" was performed if a lesion seen in CTC had been missed in the first colonoscopy. RESULTS A total of 150 lesions were detected and histologically confirmed. 136 were found to be polypoid lesions, classified as either hyperplastic polyps (n = 66) or polyps with intraepithelial neoplasia (n = 70). In the per-patient analysis only 22.4 % of patients had no polypoid lesion, 27.6 % had at least one hyperplastic and 50.0 % had at least one adenomatous lesion. Sensitivity for adenomas of all size categories was calculated 55.7 % for CTC and 92.9 % for OC. This marked difference (both for the detection of individual lesions and the per-patient analyses) does not reach significance in the two-sided McNemar test. CONCLUSIONS There was a high prevalence of lesions with intraepithelial neoplasia in this screening group. OC had a higher sensitivity than CTC in the detection of lesions smaller than 10 mm.

Abstract
Potassium channel modulatory factor 1 (KCMF1) was found upregulated in a differential screen in the metaplastic epithelium in the pancreas of transforming growth factor (TGF)-alpha transgenic mice. Expression analysis indicated broad overexpression in human cancer tissues. Therefore, we investigated the hypothesis that KCMF1 promotes metaplastic changes and tumor development. KCMF1 represents an evolutionarily highly conserved protein with a 95% identity between human and zebrafish. KCMF1 is expressed during embryonic development and in the majority of adult tissues investigated. Upregulation of nuclear KCMF1 expression is evident in preneoplastic lesions and in several epithelial malignancies, such as pancreatic cancer in mice and humans. In cell culture and in the chicken chorioallantoic membrane model, KCMF1 enhances proliferation, migration and invasion of HEK-293 and Panc1 cells. In crossbreeding experiments, KCMF1-knockdown gene trap mice showed a reduced number and size of premalignant lesions and absence of pancreatic cancer formation in TGF-alpha transgenic mice. This effect is related to the decreased expression of G1 to S cell-cycle regulators such as cyclin D and cyclin-dependent kinase (CDK) 4. Our data support the hypothesis that KCMF1 mediates pro-oncogenic functions in vitro and in vivo and downregulation of KCMF1 results in the inhibition of pancreatic cancer formation in mice. These effects are mediated through downregulation of cell-cycle control genes such as cyclin D and CDK4.

Abstract
INTRODUCTION Clinical studies have shown either positive or in some other cases negative correlations between leptinemia and bone mineral density (BMD) or bone mineral content (BMC). OBJECTIVES The aim of the present study was to assess whether these discrepancies might be associated with the effect of G(-2548)A leptin or A326G and A668G leptin receptor gene polymorphisms on serum leptin concentrations or BMD and BMC. PATIENTS AND METHODS The study included 72 obese patients (39 women and 33 men, aged 46 +/-8.8 years; body mass index [BMI] >30 kg/m2). In all subjects, serum creatinine, glucose, lipids, leptin, and insulin were determined. Total fat mass (TFM), BMC, and BMD were assessed using dual energy X-ray absorptiometry (Lunar DPX-L). RESULTS No significant correlations were observed between body mass composition parameters (TFM, lean mass, BMC) or BMD in relation to genotypes. A positive correlation was found between serum leptin concentration and BMI. An inverse association was observed between leptin concentrations and BMC. Multiple regression analysis showed independent correlations of leptinemia with sex (P <0.001), TFM (P <0.000 001), BMC (P = 0.0001), and the presence of (-2548)A allele of the leptin gene (P <0.05). These parameters together accounted for 83% of variability in serum leptin concentrations. CONCLUSIONS In obese patients, serum leptin concentration shows an independent inverse correlation with BMD and male sex, but positively with TFM and the presence of -2548A allele of leptin gene. These parameters are responsible for 83% of leptin concentration variability. No correlations between the examined polymorphisms and BMC or BMD were found.

Abstract
BACKGROUND CD147 (basigin, EMMPRIN) is a multifunctional, highly conserved glycoprotein enriched in pancreatic ductal adenocarcinomas (PDACs) which is associated with poor prognosis in many malignancies. The role of CD147 in pancreatic cancer, however, remains elusive. METHODS AND RESULTS Silencing of CD147 by RNA interference (RNAi) reduced the proliferation rate of MiaPaCa2 and Panc1 cells. CD147 is required for the function and expression of the monocarboxylate transporters MCT1 and MCT4 that are expressed in human PDAC cells as demonstrated by real-time reverse transcription-PCR (RT-PCR) as well as immunohistology. MCT1 and MCT4 are the natural transporters of lactate, and MiaPaCa2 cells exhibited a high rate of lactate production, which is characteristic for the Warburg effect, an early hallmark of cancer that confers a significant growth advantage. Further induction of lactate production by sodium azide in MiaPaCa2 cells increased MCT1 as well as MCT4 expression. CD147 silencing inhibited the expression and function of MCT1 and MCT4 and resulted in an increased intracellular lactate concentration. Addition of exogenous lactate inhibited cancer cell growth in a dose-dependent fashion. In vivo, knock-down of CD147 in MiaPaCa2 cells by inducible short hairpin RNA (shRNA)-mediated CD147 silencing reduced invasiveness through the chorioallantoic membrane of chick embryos (CAM assay) and inhibited tumourigenicity in a xenograft model in nude mice. CONCLUSION The function of CD147 as an ancillary protein that is required to sustain the expression and function of MCT1 and MCT4 is involved in the association of CD147 expression with the malignant potential of pancreatic cancer cells exhibiting the Warburg effect.

Abstract
AIM: To gain molecular insights into the expression and functions of endothelin-1 (ET-1) in pancreatic stellate cells (PSC).
METHODS: PSCs were isolated from rat pancreas tissue, cultured, and stimulated with ET-1 or other extracellular mediators. Cell proliferation was assessed by measuring the incorporation of 5-bromo-2’-deoxyuridine into DNA and cell migration was studied in a transwell chamber assay. Gene expression at the level of mRNA was quantified by real-time polymerase chain reaction. Expression and phosphorylation of proteins were monitored by immunoblotting, applying an infrared imaging technology. ET-1 levels in cell culture supernatants were determined by an enzyme immunometric assay. To study DNA binding of individual transcription factors, electrophoretic mobility shift assays were performed.
RESULTS: Among several mediators tested, transforming growth factor-β1 and tumour necrosis factor-α displayed the strongest stimulatory effects on ET-1 secretion. The cytokines induced binding of Smad3 and NF-κB, respectively, to oligonucleotides derived from the ET-1 promoter, implicating both transcription factors in the induction of ET-1 gene expression. In accordance with previous studies, ET-1 was found to stimulate migration but not proliferation of PSC. Stimulation of ET-1 receptors led to the activation of two distinct mitogen-activated protein kinases, p38 and extracellular signal-regulated kinases (ERK)1/2, as well as the transcription factor activator protein-1. At the mRNA level, enhanced expression of the PSC activation marker, α-smooth muscle actin and two proinflammatory cytokines, interleukin (IL)-1β and IL-6, was observed.
CONCLUSION: This study provides novel lines of evidence for profibrogenic and proinflammatory actions of ET-1 in the pancreas, encouraging further studies with ET-1 inhibitors in chronic pancreatitis.

Abstract
Public research funding is of growing importance for university medicine as a finance resource particularly in view of decreasing institutional budgets provided by the Federal States, as a serious stimulus for change in university medicine, and as an intra- and interuniversity research quality indicator, which is also used in the process of (re-)distributing institutional budgets. These three factors are largely determining the research in university medicine. The large funding institutions BMBF, DFG, EU have different programs and, thus, specific influence on the development of university medicine. The health research program of the BMBF focuses on clinical and patient oriented research, and gives incentives for the development of research structures of university medicine. The funding mechanism of the DFG is primarily demand oriented (bottom-up) and is focused on basic research. Nevertheless, the coordinated funding measures of the DFG are increasingly influencing the development of university medicine. The actual 7th framework program of the EU has a demand-orientated basic research program (ERC) as well as a broad structured program which also funds clinical research. With the recently invented instrument of joint programming the EU intends to influence the funding priorities of the member states.

Abstract
BACKGROUND Duodenal-Gastro-Esophageal Reflux (DGER) represents an independent risk factor for the development of complicated Gastro-esophageal-reflux-disease (GERD) and Barrett's esophagus. Clinical and epidemiological data suggest a potential association between cholecystectomy (CCE) and augmented bile reflux. METHODS 132 patients (67 women, 65 men, median age 55) with typical symptoms of GERD were enrolled in the study and divided in cholecystectomized (CCE-group: n = 107) and non- cholecystectomized (nCCE-group: n = 25) patients. Standardized clinical work-up of patients included combined esophageal 24 h pH-measurement and Bilitec 2000 esophageal manometry and upper endoscopy. RESULTS In the statistical analysis no differences between the cholecystectomized group (CCE-group, n = 25) and the patients without cholecystectomy (nCCE-group, n = 107) could be observed in quantity or quality of reflux symptoms. Furthermore, neither acid reflux nor severity of inflammation and frequency of Barrett's esophagus significantly differed between the nCCE and CCE-group. However, the percentage of patients with pathological DGER were significantly higher in the CCE-group as compared to the nCCE-group (76 vs. 55 %, p < 0.01). Moreover, the CCE-group revealed significant higher levels of pathological DGER compared to the nCCE-group (15.5 % +/- 14.1 vs. 8.6 % +/- 15.4; p < 0.05). CONCLUSION To conclude, our data provide first evidence of elevated DGER after CCE in patients with typical clinical symptoms of GERD using the Bilitec device. Both the frequency and the extent of DGER was significantly increased in the CCE-group. Prospective studies are urgently needed to elucidate the impact of CCE on DGER in patients with clinical symptoms of a reflux disease.

Abstract
Glucagon-like peptide-1 (GLP-1) is the major incretin hormone from the distal small intestine which stimulates basal and glucose-induced insulin secretion. Using the rat insulinoma cell line RINm5F (Gazdar et al. 1980) we investigated the effects of GLP-1 on insulin secretion, insulin content, and insulin receptor binding. During a 1 hour incubation, GLP-1 [1 nM] stimulated insulin secretion 2-fold (p < 0.01 vs controls). Incubating RINm5F for 24 h with GLP-1 [1 nM], a 1.6-fold higher cellular insulin content was observed (p < 0.01 vs controls). Moreover, GLP-1 induced a 2-fold higher capacity and a 15-fold higher affinity of 125I-insulin binding on the cell surface (p < 0.01 vs controls). Glucagon, known as a potent stimulator of insulin secretion, yielded a similar effect only in 1,000-fold higher concentrations, whereas the intracellular insulin content as well as insulin receptor binding was not increased. Taken together, in RINm5F insulinoma cells GLP-1 potently stimulates insulin secretion and insulin content, and improves insulin receptor binding.

Abstract
Prenalterol (H 133/22) is an adrenergic beta-receptor stimulator which unlike isoproterenol is both orally active and has a long duration of action. The inotropic, chronotropic and dromotropic effects of prenalterol were investigated in pentobarbital anaesthetized dogs. Prenalterol was found to increase left ventricular maximum dP/dt in a dose-dependent manner up to a dose level of 50 micrograms/kg. Additional doses resulted in only small further increases in cardiac contractility. Electrophysiological studies were done to compare the effects of prenalterol and isoproterenol on sinus node and ventricular pacemaker function. Complete AV block was produced by electrocauterization of the His bundle. Prenalterol accelerated both ventricular and sinus node pacemakers at doses up to 50 micrograms/kg. The increase in ventricular rate was greater than the increase in sinus rate following supramaximal inotropic doses of prenalterol yet no ventricular extrasystoles were ever observed. Similar acceleration of the ventricular and sinus node pacemakers were observed by infusion of isoproterenol. Prenalterol and isoproterenol accelerated AV nodal conduction and ventricular conduction but had little effect upon His-Purkinje conduction. Sinus node reset time was abbreviated as was the functional and effective refractory periods of the atrium and AV nodes.

Abstract
The Memory and Attention Test (MAT), a newly developed, adaptive, computer-based performance test was evaluated in a mixed group of patients with Alzheimer's dementia, subjects with mild cognitive impairment and control subjects at ages from 60 to 89 years.By means of the MAT, working memory and short-term memory are assessed in the verbal, figural and episodic domains by means of six independent tests individually adjusted to the subjects level of performance on the basis of intermediate results. Sustained attention is also assessed.For evaluation purposes, well established tests for the respective memory domains were applied. They were the Auditory Verbal and Learning Test (AVLT), the Benton Test, the delayed reproduction of the Taylor Figure, the subtests working memory and logical memory of the Wechsler Memory Scale (WMS) and the Alterskonzentrationstest (AKT), a test analogous to the d2 test, especially suited and standardized for older subjects. Acceptance of the MAT was assessed by means of a questionnaire developed for this purpose.Computerized testing was commonly well accepted by the subjects. There were highly significant positive correlations between performance in the MAT domains and performance in the respective reference assessments. Thus, the MAT may be a useful diagnostic tool for the assessment of dementia patients. It may be applied for early diagnosis, assessment of progression of disease and demonstration of treatment effects, particularly for disease-modifying treatments in Alzheimer's disease. Standardization relating to age and and education as well as the provision of versions in various languages are under way.

Abstract
Background Reduced bone mineral density (BMD) and osteoporosis are frequent in Crohn's disease (CD), but the underlying mechanisms are still not fully understood. Deficiency of sex steroids, especially estradiol (E2), is an established risk factor in postmenopausal osteoporosis. Aim To assess if hormonal deficiencies in male CD patients are frequent we investigated both, sex steroids, bone density and bone metabolism markers. Methods 111 male CD patients underwent osteodensitometry (DXA) of the spine (L1–L4). Disease related data were recorded. Disease activity was estimated using Crohn's disease activity index (CDAI). Testosterone (T), dihydrotestosterone (DHT), estradiol (E2), sex hormone binding globulin (SHBG), Osteocalcin and carboxyterminal cross-linked telopeptids (ICTP) were measured in 111 patients and 99 age-matched controls. Results Patients had lower T, E2 and SHBG serum levels (p < 0.001) compared to age-matched controls. E2 deficiency was seen in 30 (27.0%) and T deficiency in 3 (2.7%) patients but only in 5 (5.1%) and 1 (1%) controls. Patients with E2 deficiency had significantly decreased T and DHT serum levels. Use of corticosteroids for 3 of 12 months was associated with lower E2 levels (p < 0.05). Patients with life-time steroids >10 g had lower BMD. 32 (28.8%) patients showed osteoporosis, 55 (49.5%) osteopenia and 24 (21.6%) had normal BMD. Patients with normal or decreased BMD showed no significant difference in their hormonal status. No correlation between markers of bone turnover and sex steroids could be found. ICTP was increased in CD patients (p < 0.001), and patients with osteoporosis had higher ICTP levels than those with normal BMD. Conclusion We found an altered hormonal status – i.e. E2 and, to a lesser extent T deficiency – in male CD patients but failed to show an association to bone density or markers of bone turnover. The role of E2 in the negative skeletal balance in males with CD, analogous to E2 deficiency in postmenopausal females, deserves further attention.
