Abstract
Fermented rapeseed meal has the potential to partial replace soybean meal in feed mixtures for poultry without a negative impact on the health condition and performance of birds. This is due to the fact that the fermentation process can reduce the amount of antinutritional factors, improve the use of nutrients and impart probiotic properties to rapeseed meal. Therefore, this study was undertaken to investigate the effect of fermented rapeseed meal on the performance, egg quality, intestinal morphometry, the viscosity of intestinal content and total phosphorus availability. A total of 108 Lohmann Brown laying hens at 26 wk of age were used in the 90-day study. All hens were randomly divided into 3 treatment groups, with 12 replicates (cages) each, as follows: control group received no rapeseed meal, the URSM group received 3% unfermented rapeseed meal and the FRSM group received 3% fermented rapeseed meal. In the case of performance, egg traits, sensory evaluation of eggs, the viscosity of intestinal content and the availability of total phosphorus, if the distribution was normal, a 1-way analysis of variance was performed. If the distribution was not normal, the Kruskal-Wallis test was performed. In the case of histomorphometric evaluation of the intestine, if the distribution was normal, the Student t test for independent samples was performed. If not, a Mann-Whitney U test was performed. The performed analyses showed that the supplementation of fermented rapeseed meal had no negative effect on the performance of birds and the quality of eggs. Fermented rapeseed meal was also associated with improved histomorphometric parameters of the small intestine compared to the group receiving unfermented rapeseed meal in the feed. Laying hens from FRSM group were characterized by significantly lower viscosity of intestinal content (P < 0.05) compared to URSM group. Phosphorus in FRSM group was significantly more available to the birds (P < 0.05) compared to URSM group. These results suggest that supplementation with fermented rapeseed meal may be beneficial, especially in times of unstable prices of soybean meal and problems with its availability.

Abstract
The naiads, large freshwater mussels (Unionida), have very long life spans, are large-bodied, and produce thousands to millions of larvae (glochidia) which typically must attach to host fish tissues to metamorphose into a juvenile mussel. Glochidia develop within a female's marsupial gill demibranch, thus their number is restricted by female size. However, larger mussels acquire more energy, which could be invested in either larger-sized glochidia, in a more glochidia, or a combination of both. The high level of host specialization seen in many naiads may constrain glochidial size and shape around a narrow optimum, while naiads that use a wide range of host fishes may be predicted to possess greater plasticity in glochidial morphology. In this paper, we investigated the relationship between maternal body size and progeny body size and shape, aided by modern digital microscopy. We analyzed the between- and within- species variation of glochidia size and shape relative to female size in four widespread species of European naiads: Anodonta anatina, Anodonta cygnea, Unio crassus and Unio tumidus. Whereas the total reproductive output is collinear with female body size, substantial differences between species in glochidia size were found within genus Anodonta, but not genus Unio where glochidial size is remarkably consistent. The glochidial shape, however, differed within both Unio and Anodonta. We interpret this constant within-species glochidial size in Unio as reflecting a constraint imposed by the likelihood of successful transmission onto and off from a narrow range of hosts, whereas their shape seems to be less constrained. The Anodonta species, inhabiting a wide spectrum of habitats and using more than twice the number of fish hosts than Unio spp., have larger glochidia with greater variation in size and shape. Our results suggest that measures of glochidial variability may also serve as an indicator of host specificity in other naiads.

Abstract
The lungs are a common site of metastases from malignant tumors. Their removal with a minimal but safe tissue margin is essential for the long-term survival of patients. The aim of this study was to evaluate the usefulness of a 1940 nm thulium-doped fiber laser (TDFL) and a 1470 nm diode laser (DL) in a pig model of lung surgery that involved the incision and excision of lung tissue. Histopathological analysis was performed on days 0 and 7 after surgery. Neither TDFL nor DL caused significant perioperative or postoperative bleeding. Histological analysis revealed the presence of carbonized necrotic tissue, mixed fibrin-cellular exudate in the superficial zone of thermal damage and bands of deeper thermal changes. The mean total width of thermal damage on day 0 was 499.46 ± 61.44 and 937.39 ± 109.65 µm for TDFL and DL, respectively. On day 7, cell activation and repair processes were visible. The total width of thermal damage was 2615.74 ± 487.17 µm for TDFL vs. 6500.34 ±1118.02 µm for DL. The superficial zone of thermal damage was narrower for TDFL on both days 0 and 7. The results confirm the effectiveness of both types of laser in cutting and providing hemostasis in the lungs. TDFL caused less thermal damage to the lung parenchyma than DL.

Abstract
Purpose Healing of osteoporotic defects is challenging and requires innovative approaches to elicit molecular mechanisms promoting osteoblasts-osteoclasts coupling and bone homeostasis. Methods Cytocompatibility and biocompatibility of previously characterised nanocomposites, i.e Ca5(PO4)3OH/Fe3O4 (later called nHAp/IO) functionalised with microRNAs (nHAp/IO@miR-21/124) was tested. In vitro studies were performed using a direct co-culture system of MC3T3-E1 pre-osteoblast and 4B12 pre-osteoclasts. The analysis included determination of nanocomposite influence on cultures morphology (confocal imaging), viability and metabolic activity (Alamar Blue assay). Pro-osteogenic signals were identified at mRNA, miRNA and protein level with RT-qPCR, Western blotting and immunocytochemistry. Biocompatibility of biomaterials was tested using bilateral cranial defect performed on a senescence-accelerated mouse model, ie SAM/P6 and Balb/c. The effect of biomaterial on the process of bone healing was monitored using microcomputed tomography. Results The nanocomposites promoted survival and metabolism of bone cells, as well as enhanced functional differentiation of pre-osteoblasts MC3T3-E1 in co-cultures with pre-osteoclasts. Differentiation of MC3T3-E1 driven by nHAp/IO@miR-21/124 nanocomposite was manifested by improved extracellular matrix differentiation and up-regulation of pro-osteogenic transcripts, ie late osteogenesis markers. The nanocomposite triggered bone healing in a cranial defect model in SAM/P6 mice and was replaced by functional bone in Balb/c mice. Conclusion This study demonstrates that the novel nanocomposite nHAp/IO can serve as a platform for therapeutic miRNA delivery. Obtained nanocomposite elicit pro-osteogenic signals, decreasing osteoclasts differentiation, simultaneously improving osteoblasts metabolism and their transition toward pre-osteocytes and bone mineralisation. The proposed scaffold can be an effective interface for in situ regeneration of osteoporotic bone, especially in elderly patients.

Abstract
INTRODUCTION Bleeding is a major complication of anticoagulation in acute pulmonary embolism (APE) while estimating individual bleeding risk remains challenging. Elevated D-dimer levels (DD) have been shown to predict bleeding events. OBJECTIVES (1) direct comparison of the capacity of bleeding risk prediction scores (VTE-BLEED, RIETE, HAS-BLED, HEMORR2HAGES) to prognosticate in-hospital bleeding events in the acute phase of APE in a real-life population of APE patients;(2) augmentation of the discriminative capacity of fore mentioned scores with DD. MATERIALS Post-hoc analysis of a prospective observational study. DD levels were measured using the VIDAS D-dimer Exclusion test. Receiver operating characteristic curves, areas under the curve (AUC) for bleeding prediction were calculated for scores and DD. Bleeding scores+DD were compared using an established index quantifying the reclassification of patients (net reclassification index, NRI). RESULTS 310 APE patients were included. 35(11.3%) bleeding events occurred (hematomas, GI, urinary tract, retroperitoneal, uterine, CNS, respiratory tract): 17 major (MB) and 18 clinically-relevant non-major bleedings (CRNMB), none were fatal. All scores had satisfactory AUCs (0.754-0.767), except HAS-BLED (AUC = 0.512; 0.455-0.569). DD were higher in patients with bleeding events (29,911 ng/ml vs. 4805 ng/ml, p = .031), AUC 0.621(0.520-0.721), p = .02. DD = 5750 ng/ml was characterized by OR = 2.3(95%CI 1.05-5.0) for all bleeding events. Adding DD improved the discriminatory capacity of tested scores in the non-high risk of bleeding category, NRI 0.07-03. CONCLUSIONS Of the tested scores RIETE, HEMORR2HAGES, VTE-BLEED performed best at identifying APE patients at risk of in-hospital bleeding complications. DD levels may predict in-hospital bleeding events and may improve identifying patients classified as non-high risk who experience bleeding complications.

Abstract
BACKGROUND AND AIM Patients with acute pulmonary embolism (APE) associated with hemodynamic instability, i.e. high-risk APE (HR-APE), are at risk for early mortality and require urgent reperfusion therapy with thrombolysis or embolectomy. However, a considerable proportion of HR-APE subjects is not reperfused but only anticoagulated due to high bleeding risk. The aim of the present study was to assess the management of HR-APE in a single large-volume referral center. METHODS A single-center retrospective study of 32 HR-APE subjects identified among 823 consecutive patients hospitalized for symptomatic APE. RESULTS Out of 32 subjects with HR-APE (19 women, age 69 ± 19 years), 20 patients were unstable at admission and 12 subsequently deteriorated despite on-going anticoagulation. Thrombolysis was applied in 20 (62.5%) of HR-APE subjects, limited mainly by classical contraindications in the remainder. Percutaneous pulmonary embolectomy was performed in 4 patients. In-hospital PE-related mortality tended to be higher, albeit insignificantly, in the patients who developed hemodynamic collapse during the hospital course compared to those unstable at admission (67% vs. 40%, p = 0.14). Also, survival was slightly better in 22 patients treated with thrombolysis or percutaneous embolectomy in comparison to 10 subjects who received only anticoagulation (54% vs. 40%, p = 0.2). Major non-fatal bleedings occurred in 7 of 20 patients receiving thrombolysis (35%) and in 2 (17%) of the remaining non-thrombolysed 12 HR-APE subjects. CONCLUSIONS Hemodynamically instability, corresponding to the definition of HR-APE, affects about 4% of patients with APE, developing during the hospital course in approximately one-third of HR-APE subjects. As almost 40% of patients with HR-APE do not receive thrombolytic therapy for fear of bleeding, urgent percutaneous catheter-assisted embolectomy may increase the percentage of patients with HR-APE undergoing reperfusion therapy. Further studies are warranted for a proper identification of initially stable intermediate-risk APE subjects at risk of hemodynamic collapse despite appropriate anticoagulation.

Abstract
Background Cells adapt to hypoxia by transcriptional induction of genes that participate in regulation of angiogenesis, glucose metabolism and cell proliferation. The primary factors mediating cell response to low oxygen tension are hypoxia inducible factors (HIFs), oxygen-dependent transcription activators. The stability and activity of the α subunits of HIFs are controlled by hydroxylation reactions that require ascorbate as a cofactor. Therefore, deficiency of intracellular vitamin C could contribute to HIFs overactivation. In this study, we investigated whether vitamin C content of human thyroid lesions is associated with HIF-1α and HIF-2α protein levels. Methods Expression of HIF-1α and HIF-2α as well as vitamin C content was analyzed in thyroid lesions and cultured thyroid carcinoma cell lines (FTC-133 and 8305c) treated with hypoxia-mimetic agent (cobalt chloride) and ascorbic acid. The expression of HIFs and hypoxia–induced glucose transporters were determined by Western blots while quantitative real-time PCR (qRT-PCR) was performed to detect HIFs mRNA levels. Ascorbate and dehydroascorbate levels were measured by HPLC method. Results We found an inverse correlation between vitamin C level and HIF-1α but not HIF-2α expression in thyroid lesions. These results agree with our in vitro study showing that vitamin C induced a dose - dependent decrease of HIF-1α but not HIF-2α protein level in thyroid cancer cells FTC-133 and 8305C. The decreased HIF-1α expression was correlated with reduced expression of hypoxia-related glucose transporter 1 (GLUT1) in thyroid cancer cells. Conclusion The results demonstrate that HIF-1α activation is associated with vitamin C content in thyroid lesions. Our study suggests that high tumor tissue ascorbate level could limit the expression of HIF-1α and its targets in thyroid lesions.

Abstract
Enhanced glucose requirement of cancer cells is associated with an increased glucose transport across plasma membrane that is mediated by a family of facilitated glucose transporter proteins, named GLUTs. GLUT1 is the main transporter in thyroid cancer cells. Glucose is the principal physiological substrate of GLUT1; however, it is also capable of transporting of oxidized form of vitamin C [i.e., dehydroascorbic acid (DHAA) which inside the cells is reduced to ascorbic acid (AA)]. The objective of this study was to determine the effect of normo-, hypo-, and hyperglycemia conditions on GLUT1-dependent intracellular ascorbate accumulation and viability of thyroid cancer cells. GLUT1 seems to be the main DHAA transporter in thyroid cancer cells because its knockdown by RNAi reduced DHAA accumulation by more than 80%. The results showed that in thyroid cancer cells high glucose inhibits both transport of AA and DHAA. Inhibition of vitamin C transport by glucose had a cytotoxic effect on the cells. However, stabilization of vitamin C in one of 2 forms (i.e., AA or DHAA) abolished this effect. These results suggest that cytotoxic effect is rather associated with extracellular accumulation of vitamin C and changes of its oxidation state than with intracellular level of ascorbate.

Abstract
Systemic sclerosis (SSc) is an autoimmune disorder characterized by skin and internal organs fibrosis and concomitant vascular abnormalities. Although SSc is considered mainly fibrosing disease, underlying vascular pathology plays a fundamental role in its pathogenesis. We have focused on positive and negative serum markers of angiogenesis and fibrosis (pigment epithelium-derived factor [PEDF], vascular endothelial growth factor [VEGF], and soluble VEGF receptor [sVEGFR]), in progressive SSc patients at baseline and after follow-up in relation to cardiopulmonary complications (systemic hypertension [HT], pulmonary arterial hypertension [PAH] and pulmonary fibrosis [PF]). VEGF and PEDF but not sVEGFR were reciprocally regulated in SSc progression. Moreover, VEGF/PEDF ratio significantly increased during follow up suggesting that it might be used as a biomarker of disease progression. No correlation between the studied markers and cardiopulmonary complications was observed. In conclusion, VEGF and PEDF level, and the VEGF/PEDF ratio are significantly changed in the course of SSc progression and these markers can be used to assess SSc activity.

Abstract
BACKGROUND Early identification of high-risk individuals is key for the prevention of cardiovascular disease (CVD). The aim of this study was to assess the potential impact of a family history of metabolic syndrome (fhMetS) on the risk of metabolic disorders (abnormal body mass, lipid profile, glucose metabolism, insulin resistance, and blood pressure) in healthy young individuals. METHODS We studied CVD risk factors in 90 healthy volunteers, aged 27-39 years; of these, 78 had fhMetS and 12 were without fhMetS (control group). Fasting serum lipids, glucose, and insulin levels were assayed, and anthropometric parameters and blood pressure using, an ambulatory blood pressure monitoring system, were measured. Nutritional and physical activity habits were assessed. RESULTS Despite similar nutritional and physical activity habits, abnormal body mass was found in 53.2% of the fhMetS participants and 46.1% of the control participants (p = 0.54). The occurrence of obesity was 19.4% and 0%, respectively (p = 0.69). Compared to the control participants, fhMetS was associated with significantly higher total cholesterol (5.46 mmol/L vs. 4.69 mmol/L, p < 0.030), low-density lipoprotein cholesterol ( 3.28 mmol/L vs. 2.90 mmol/L, p < 0.032), and non-high-density lipoprotein cholesterol ( 3.74 mmol/L vs. 3.25 mmol/L, p < 0.016) levels, in addition to lower fasting glucose levels ( 4.51 mmol/L vs. 4.81 mmol/L, p < 0.042). A positive correlation between fasting glucose and insulin levels (r = 0.28; p < 0.015) was detected in the fhMetS participants. Higher mean daytime systolic blood pressure (121.5 mmHg vs. 113.3 mmHg, p < 0.035), mean daytime diastolic blood pressure ( 79.0 mmHg vs. 74.5 mmHg, p < 0.045), and mean nighttime diastolic blood pressure ( 64.0 mmHg vs. 59.5 mmHg, p < 0.019) were observed in the fhMetS group. CONCLUSIONS More than 50% of the fhMetS participants had excess weight or a lipid disorder, which may indicate an increased risk of cardiovascular disease and the need for regular ambulatory assessment of serum lipid concentrations in young people with a family history of MetS.

Abstract
Insulin significantly influences Ca(2+) signals evoked by various stimulants. In type 1 recent onset diabetes mellitus the proliferative response of T cells is significantly decreased. The number of clinical trials exploring the role of anti-CD3 monoclonal antibodies (mAb) as a therapeutic agent in recent onset diabetes mellitus type 1 is increasing last years. Therefore, a better understanding of the interplay between T cell receptor (TCR) dependent Ca(2+) increase, and insulin is of vital clinical significance. The aim of the study was to assess the effect of insulin on TCR evoked Ca(2+) responses in T lymphocytes obtained from healthy volunteers and patients suffering from long lasting diabetes mellitus type 1. Analysis was performed with use of the flow cytometer. We demonstrated that T cells ability to mobilize Ca(2+) was significantly reduced in long lasting diabetes mellitus type 1. Ca(2+) decrease achieved by the long term incubation with anti-CD3 mAb in T cells from healthy volunteers was restored by insulin. Strong interrelationship between baseline Ca(2+) level and plateau phase response to TCR stimulation was observed in the cytoplasm of cells pre-incubated with insulin from both healthy subjects and diabetic patients (r = 0.95, p < 0.0001 and r = 0.94, p < 0.0001, respectively). We postulate the existence of the interplay between TCR mediated activation and insulin. The TCR-insulin interplay is blunted in long lasting diabetes mellitus type 1. These observations may have an important implication for future therapeutic options in diabetes.

Abstract
The enhancement of glucose metabolism in neoplastic cells is mediated by the overexpression of key glycolytic enzymes and glucose transporters (GLUTs). In particular, an increased expression of hypoxia-related GLUT1 and GLUT3 has been found in a variety of malignancies. The aim of this study was to examine the expression levels of GLUT1 and GLUT3 in benign and malignant thyroid tumors, as well as in non-neoplastic lesions. Analysis of the mRNA expression levels of solute carrier family 2, member 1 (SLC2A1) and solute carrier family 2, member 3 (SLC2A3) (genes coding GLUT1 and GLUT3, respectively) was performed by the real-time PCR method with fluorescent probes. GLUT1 and GLUT3 protein expression levels were determined in thyroid specimens by immunodetection after separation of proteins on 10% polyacrylamide slab gels and electrotransfer onto Immobilon-P membranes. The majority of papillary carcinoma samples showed a higher expression of GLUT1 and GLUT3 in comparison with follicular carcinoma cases and non-neoplastic thyroid lesions. A tendency towards an increased expression of GLUT1 and GLUT3 was observed in papillary carcinoma cases with more advanced disease stages. Moreover, a significant correlation was noted between the hypoxia-related GLUT1 and GLUT3 expression determined by both methods. In conclusion, our findings suggest that GLUT1 and GLUT3 play an important role in the pathology of thyroid glands.

Abstract
Malignant cells are known to enhance glucose metabolism, to increase glucose uptake and to inhibit the process of oxidative phosphorylation. Accelerated glycolysis is one of the biochemical characteristics of cancer cells that allow them to compensate the inefficient extraction of energy from glucose in order to continue their uncontrolled growth and proliferation. Upregulation of glucose transport across the plasma membrane is mediated by a family of facilitated glucose transporter proteins named GLUT. Overexpression of GLUTs, especially the hypoxia-responsive GLUT1, has been frequently observed in various human carcinomas. Many studies have reported a correlation between GLUT1 expression level and the grade of tumor aggressiveness, which suggests that GLUT1 expression may be of prognostic significance. Therefore, GLUT1 is a key rate-limiting factor in the transport and glucose metabolism in cancer cells. This paper presents the current state of knowledge on GLUT1 regulation as well as its utility in the diagnosis and therapy of cancers.

Abstract
The serine/threonine protein kinase Akt is a key molecule in the phosphatidyl inositol 3-kinase pathway that is often overactivated in human cancers. Three Akt isoforms (Akt1, Akt2, Akt3) have been identified in human cells and they show different distribution and have non-redundant functions. The aim of this study was to determine whether the expression, phosphorylation, and localization of Akt1 isoform in human thyroid malignant lesions are different from those in benign lesions. Nuclear and cytoplasmic fractions were isolated from tissue samples and Western blot method was used to detect Akt1 presence in both cellular fractions. Akt1 expression was also assessed by ELISA method. To estimate Akt1 phosphorylation, kinase was immunoprecipitated from cell lysates and tested with anti-phospho-Akt antibodies. The Akt1 expression in majority of thyroid cancer samples was significantly higher than in benign lesions (p < 0.05). Akt1 both in differentiated cancers (follicular and papillary) and benign lesions was localized mainly in cytoplasmic fraction. In two of three anaplastic cancer samples Akt1 was predominantly localized in nucleus. The ratio of phosphorylated Akt1 to total Akt1 was lower in cancers than in non-neoplastic lesions and adenomas. Thus, although Akt1 seems to be overexpressed in thyroid neoplasms, its high phosphorylation is not characteristic for thyroid cancers.

Abstract
O-GlcNAcylation is a common and dynamic modification of intracellular proteins in which β-N-acetyl-glucosamine moieties are attached to hydroxyl groups of serine or threonine residues (O-GlcNAc). Accumulating evidence suggests the critical role of protein O-GlcNAcylation in signal transduction, transcriptional control, cell cycle regulation and protein degradation. However, the exact role of O-GlcNAc modification in tumor pathogenesis or progression remains to be established. In the present study, we investigated the effect of increased O-GlcNAcylation of cellular proteins on IGF‑1 signaling in 8305C thyroid anaplastic cancer cells. The global O-GlcNAc level in the 8305C cells was increased by down-regulation of β-N-acetyl-D-glucosaminidase (O-GlcNAcase) activity, an enzyme which removes O-GlcNAc moieties. We demonstrated here that IGF‑1 stimulates Akt1 activity in 8305C cells, and down-regulation of O-GlcNAcase activity by the chemical inhibitor PUGNAc or RNA interference method enhances this effect. Increased Akt1 activation increased cell proliferation. In cells with down-regulation of O-GlcNAcase activity, kinase GSK3β phosphorylation and cyclin D1 levels were higher than those in control cells. Our findings suggest that increased proliferation of 8305C cells treated with PUGNAc or RNAi against O-GlcNAcase at least partially depends on the IGF‑1-Akt1-GSK3β-cyclin D1 pathway.

Abstract
RNA interference is one of the most important discoveries in the field of molecular biology. To date, many studies have been reported which suggest that RNA interference takes part in various biological processes essential for the development of many diseases. On the other hand, owing to its high specificity and efficiency, RNA interference has become a powerful tool in gene therapy. However, introduction of small interfering RNAs (siRNAs) to a target tissue requires overcoming some critical biological barriers. This, in turn, contributes to searching for new effective vectors, which should selectively penetrate the tissue and be able to exclude the innate immune response. This study provides a brief overview of the application of RNA interference in the diagnosis and therapy of some human diseases.

Abstract
OBJECTIVES Noninvasive fetal RHD genotyping from maternal plasma of RhD(/-) pregnant women of Caucasian race may be used for predicting the risk of hemolytic disease because the RHD gene is usually absent in such populations. If detected in plasma of such women, the RHD gene originates from the RhD(+) fetus. The number of fetal copies of the gene in maternal plasma is extremely small. In the presented case of the RhD(/-) pregnant woman with anti-D it was impossible to give a fetal RHD result due to mother's RHD(+) genotype. The fetal RHD was determined from amniocytes. AIM to present the difficulties related to the interpretation of results of invasive and noninvasive procedures. MATERIAL AND METHODS whole blood, plasma and amniotic fluid of the RhD(-) woman with anti-D (14 week of pregnancy) as well as whole blood of the newborn. RHD and RHCE*c were genotyped by real-time PCR in DNA isolated from maternal plasma and amniocytes and the RHD and d-genotypes were tested by SSP methods in DNA isolated from whole blood and amniocytes. RESULTS RHD and RHCE*c were detected in DNA isolated from plasma. The high level of RHD suggested its origin from the mother's DNA therefore it was impossible to determine the fetal RHD. The d-little test identified a RHD(IVS3+ 1G>A) variant in the mother's genome. A weak signal of real-time PCR for the RHD was obtained in amniocytes but the RHD was not detected by SSP. The RHCE*c was detected by both methods. Results were inconclusive; the fetal RHD status remained unknown. The child was RhD(-) with RHD in its DNA undetected by either method. CONCLUSIONS 1/The RHD(IVS3+ 1G>A) variant in the RhD(-) mother precluded formal noninvasive fetal RHD genotyping. 2/Real-time PCR is too sensitive for amniocyte testing and may lead to false results as it detects trace maternal DNA in amniotic fluid. 3/The frequency of RHD(IVS3+1G>A) occurrence in Poland requires further studies.

Abstract
Hyperglycaemia increases inflammatory cytokine concentration in the blood. Elevated levels of interleukin-18 (IL-18), a cytokine belonging to the interleukin-1 (IL-1) family, were recently reported in patients with Type 2 diabetes mellitus (DM2) and nephropathy. The aim of the present work was an examination of IL-18 concentration in the sera of elderly DM2 patients with nonproliferative retinopathy and age-matched control people and an estimation whether this cytokine plays pro- or anti-angiogenic role in in vivo angiogenic activity of their sera in mice cutaneous angiogenesis test. Recombinant human IL-18 injected intradermally to murine skin induced significant neovascular reaction. DM2 patients sera contained higher concentration of IL-18 and induced stronger neovascular reaction in mice skin than did the sera of corresponding control people. Sera from both groups of people after neutralization with antihuman IL-18 antibodies lost substantial part of their angiogenic activity.

Abstract
Diabetes is associated with a hypercoagulable state. Eighty percent of patients with diabetes mellitus die due to various thrombotic vascular complications. Disorder of coagulation and fibrynolysis is associated with diabetic retinopathy and nephropathy. Angiogenesis requires degradation of vascular basement membrane prior to migration and proliferation of endothelial cells. Various serine proteases play important role in this process. The homeostatic system is also the source of endogenous inhibitors of angiogenesis. Human serum contains various factors able to induce or suppress formation of new blood vessels. The aim of the present study was to evaluate the activity of some angiogenesis inhibitors, anti-proteases, anti-thrombin III, a1 anti-trypsin and a2 anti-plasmin in sera of patients with diabetes mellitus type 1 and 2 and non-proliferative retinopathy, and to correlate this activity to total angiogenic potential of these sera, measured by mice cutaneous test. Sera of 22 persons with DM1, aged 33-70 years, 35 persons with DM2, aged 37-79 years, and 51 healthy people, aged 22-80 years (as control group) were studied. Direct serum-induced cutaneous angiogenesis test in mice (SIA) was applied. Berichrom (ade Behring) tests and immunoturbidimetric method were used for evaluation of anti-proteases activity. Angiogenic activity of DM1 patients sera was statistically lower than this parameter in DM2 patients and in control group. Levels of anti-proteases were similar in DM1, DM2 and control group, with one exception: anti-thrombin level was lower in DM2 patients' sera than this in the control group. Analysis of correlation revealed important difference in behaviour of DM1 sera, as compared to other groups. Significant negative correlation was observed between angiogenic activity and anti-thrombin, as well as anti-trypsin level of DM1 patients' sera. On the other hand, correlation analysis performed for the sera of control group revealed significant positive correlation between their angiogenic activity and anti-thrombin level. No other correlations were found.

Abstract
Galectin-3 is a 31 kDa member of a growing family of beta-galactoside-binding animal lectins. This protein is expressed in a variety of tissues and cell types and is mainly found in the cytoplasm, although, depending on cell type and proliferative state, a significant amount of this lectin can also be detected in the nucleus, on the cell surface or in the extracellular environment. Galectin-3 is secreted from cells by a novel and incompletely understood mechanism that is independent of the classical secretory pathway through the endoplasmic reticulum/Golgi network. Galectin-3 exhibits pleiotropic biological function, playing a key role in many physiological and pathological processes.

Abstract
Diabetic retinopathy is one of the most common causes of blindness. The majority of studies concerning this problem were performed in patients with late stage of disease, demonstrating proliferative retinopathy, when malformations of retinal vessels became irreversible. Numerous angiogenic factors related to retinal angiogenesis have been described. Among them, VEGF is thought to be the major mediator of proliferative retinopathy. Our present study was performed on sera collected from patients with earlier stage of ocular complications, manifested as background retinopathy. We have believed that the knowledge of the earliest events leading to pathological angiogenesis may be valuable for establishing some prophylactic regimens. Sera of 22 persons with DM1, aged 33-70 years, 37 persons with DM2, aged 37-79 years, 51 healthy people, aged 22-80 years (as controls) were studied. Direct serum-induced cutaneous angiogenesis test in mice (SIA) was applied. VEGF concentration in sera was mesured by ELISA (R & D Systems) test. Angiogenic activity and VEGF concentration of DM1 patients sera were highly statistically lower than these parameters in DM2 patients and controls.

Abstract
Differences in glycosylation of nuclear and cytosolic proteins isolated from benign and malignant human thyroid neoplasms were analyzed by lectin blotting and enzyme linked lectino-solid-phase assay using Erythrina cristagalli and Ricinus communis agglutinins. The results reported in this study have not shown any significant differences in lectin binding by nuclear proteins of benign and malignant tumors, however, quantitative and qualitative differences were observed in the patterns of cytosolic glycoproteins. In the majority of carcinomas samples lectin binding to cytosolic proteins was definitely weaker in comparison with adenomas and non-neoplastic specimens, which suggested alterations in glycosylation of cytosolic proteins in malignant tumors.

Abstract
Glycoproteins which participate in DNA-protein cross-links induced by action of cis-diamminedichloroplatinum (cis-DDP) in intact nuclei of chicken liver were investigated. Digoxigenin-labelled lectins with different sugar specificity were used for detection and characterization of these glycoproteins. Our results showed the presence of glycoproteins bearing high mannose as well as complex type oligosaccharides in chicken liver nuclei. In most cases of complex oligosaccharides, sialic acid residues bound in alpha(2-6) but not in alpha(2-3) linkage were present.

Abstract
In order to examine whether the patterns of nuclear and chromatin glycoproteins change during development the glycoproteins of foetal and adult chicken liver were investigated. Nuclear and chromatin proteins from both sources were separated by SDS-PAGE, transferred onto Immobilon-P transfer membrane or nitrocellulose and tested for concanavalin A (Con A), Galanthus nivalis agglutinin (GNA) and Aleuria aurantia agglutinin (AAA) binding. Results revealed a similarity in the profiles of nuclear and chromatin glycoproteins recognized by Con A from 14-, 16-, 18-day foetal and adult chicken liver. Generally GNA and AAA reacted more weakly with glycoproteins from foetal liver compared with the same glycoproteins from adult liver.

Abstract
There are numerous glycoproteins recognized by Concanavalin A (ConA) and Galanthus nivalis agglutinin (GNA) in 0.35 mol/l NaCl soluble fraction of chromatin proteins loosely bound to DNA from hamster, chicken and frog liver cells. Results of our detailed comparative analysis show a marked similarity between liver chromatin glycoproteins from the examined animals. The presence of similar chromatin glycoproteins in different animal species may indicate that they play an important universal role in the liver cells.

Abstract
Disturbances in bone marrow vascularisation can be one of the causes of diabetic osteopathy. The aim of the study was to answers the question if microalbuminuria as a results of capillary injury can be a sign of bone mineralisation disorders in IDDM renal sufficient patients. We examined 60 IDDM patients (30 women without menstruation disturbances; 30 men; age 25-36 years old). All the observed subjects were divided into groups: I-30 normoalbuminuric patients (0-29 mg/24 h); II-30 microabuminuric patients (30-295 mg/24 h). Bone mineral density (BMD) of femoral neck, lumbar spine (L2-L4) and total body was measured by dual energy X-ray absorptiometry (DEXA, Lunar). The biochemical parameters of bone turnover were measured both in serum and urine as follows: osteocalcine, total hydroxyproline (HPR, HPR/Cr), total alkaline phosphatase (AP) with bone fraction, total calcium (Ca, Ca/Cr) and inorganic phosphor (P). Microalbuminuric patients presented more severe bone turnover disturbances, shown by differences in: BMD and Z-score for femoral neck (p < 0.05), serum HPR (p < 0.05), AP (p < 0.05), AP (p < 0.01) and its bone fraction (p < 0.05). We proved the presence of statistically significant correlation coefficients for albuminuria and some densytometric and biochemical bone parameeters. Our results suggest that microalbuminuria can indirectly indicate the dynamic of bone turnover derangement in IDDM course. They are present mostly in the femoral neck, which because of the vascularisation type is particularly susceptible to subalimentation in the diabetic microangiopathy course.

Abstract
The effect of carbohydrate moieties on the stability of hamster liver nuclear glycoproteins in the course of endogenous proteolysis employing highly specific digoxigenin-labelled lectins, was studied. Whole hamster liver nuclei were autolysed in optimum conditions for the action of nuclear proteinases able to degrade histones as well as non-histone proteins. Incubated samples were electrophoresed on sodium dodecyl sulphate-polyacrylamide gel. Coomassie blue stained gels demonstrated degradation of some proteins in particular after 18 and 24 h incubation. Proteins with molecular weights of about 46, 54 and 76 kD appeared to be resistant to proteolysis. The same location and intensity of bands of glycoproteins on immunoblots from incubated and nonincubated samples of nuclei indicated that oligosaccharide chains protect proteins from degradation.

Abstract
One of insulin-dependent diabetes mellitus (IDDM) complications are bone mineral disorders called diabetic osteopathy. Because of many controversies of this subject we took a research of bone mineralisation in IDDM patients before 40 years old. The evaluation of BMD was performed with the use of X-ray dual energy absorptiometry--DEXA in the AP projection for lumbar part of vertebral column (BMD L2-L4), left femur neck (BMD-neck) and total skeleton (BMD-total). Bone tissue metabolism was evaluated with the aid of biochemical tests. The examined group consisted of 99 patients with IDDM (45 women and 54 men), without any other risk factors for changes in bone metabolism. The results were related to: sex, age in which IDDM was diagnosed, duration of IDDM, metabolic control of diabetes and to some IDDM complications. The control group consisted of 113 healthy subjects matched for age, sex, weight, height and calcium diet. We observed that BMD in IDDM patients before 40 years old was significantly lower than in healthy subject. One of some diabetic osteopathy pathomechanism seems to be an advantage of bone resorption over bone formation. Bone demineralisation which was observed to be most pronounced in femur neck, was not related to age, differed in accordance to sex and was higher of age when IDDM appeared was lower. BMD was also related to duration of IDDM and metabolic control of IDDM.

Abstract
We studied the age-related patterns of lectin-binding liver nuclear glycoproteins from hamsters between 5 and 35 weeks of age. The examinations of the carbohydrate structures of liver nuclear glycoproteins in relation to the age of hamsters were carried out after electrophoresis and blotting by a very sensitive immunological detection system with highly specific digoxigenin-labelled lectins. The results reported in the present study do not show any significant changes in the patterns of nuclear glycoproteins with regards to the age of hamsters except the decrease in affinity of wheat germ agglutinin (WGA) to 63 kDa glycoprotein bearing single O-linked N-acetylglucosamine residues.

Abstract
There is presented a case a 42 year old woman, who was admitted to the Department of Internal Diseases, the Institute of Dentistry, Medical Academy in Warsaw, with suspected bacterial endocarditis. Two episodes which indicate a lesion in the central nervous system (as right side hemiparesis and mixed aphasia) in the patients with valvular heart disease, were the basis of this suspicion. Bacterial endocarditis was not confirmed during hospitalisation. Diagnosis of Sneddon's syndrome was established based on skin lesion of livedo reticulatis type with typical picture in skin biopsy and on the lesions in the central nervous system confirmed by MRI. Moreover the patients had arterial hypertension and Raynaud's syndrome. We presented the diagnostic difficulties of Sneddon's syndrome, a course of the disease, the factors, which affect its prognosis and attempts to treat this syndrome based on this case.

Abstract
1. As a further step toward characterizing nonhistone protein of mol. wt 48,000 which was found to be much more abundant in animal tumour cells than in normal ones [Krajewska W.M., Lipínska A., Marszatek M., Kiliańska Z., Wojtkowiak Z. and Kłyszejko-Stefanowicz L. Cell. Biochem. Funct. 8, 79-89 (1990)] its intranuclear localization in hamster liver and Kirkman-Robbins hepatoma was studied. The protein was identified by immunoblotting technique in the presence of antibodies against polypeptide of mol. wt about 48,000 from Kirkman-Robbins hepatoma. 2. Distribution of antigen with mol. wt of 48,000 in nuclear fractions representing different levels of nuclear material organization, i.e. in nucleoli, nuclease-sensitive and nuclease-resistant fractions, and extensive nuclease digestion products separated by size on Bio-Gel A-50m; implied the structural role of this component. 3. Fractionation of endogenously digested nuclei into low salt extract, high salt extract and nuclear matrix revealed that in normal liver the antigen studied is associated with nuclear matrix while in hepatoma this component appeared in high salt extract. 4. These results suggest that polypeptide with mol. wt of 48,000 is a shuttling protein which may be involved in reorganization of nuclear matrix during neoplastic transformation.

Abstract
1. Preliminary results of comparative electrophoretical and immunological analyses of the components of two classes of non-histone proteins, i.e. NHP1 and NHP2 eluted from hydroxyapatite allowed to suppose that protein of Mw 18,000 is specific for animal tumour cells. 2. However, the studies on cellular distribution of this polypeptide indicated that it is exclusively located in nuclei of hepatoma and normal liver as well. 3. The former observation seems to be the result of changes of the affinity of this protein to DNA during neoplastic transformation.

Abstract
A non-histone protein with mol. wt of 48,000 differentially expressed in normal and tumour cells was identified using immunological criteria. Antibodies were raised against a component specific for Kirkman-Robbins hepatoma of mol. wt about 48,000 separated from hepatoma non-histone proteins by preparative electrophoresis in polyacrylamide gel. It was demonstrated by immunoblotting that Morris hepatoma 7777 and Ehrlich ascites cells share an antigenic non-histone protein with Kirman-Robbins hepatoma. Tumour cells when compared with normal cells, i.e. hamster and rat liver, are characterized by significant enrichment of this component. Intracellular distribution of the polypeptide with mol. wt 48,000 suggests that this component may be a structural protein the biosynthesis of which increases or the antigenic determinants of which change in tumour cells.

Abstract
The immunochemical localization of hamster liver nucleolar antigens in subcellular fractions (nuclei, 10,000 x g pellet, 100,000 x g pellet and supernatant), nuclear substructures (chromatin, nuclear matrix, nuclear envelope, nucleoli, RNP particles and nucleosomes), and three classes of nonhistone chromosomal proteins with different affinities to DNA (NHCP1, NHCP2 and NHCP3) from nuclease-sensitive and nuclease-resistant chromatin fractions of hamster liver were studied. Six main nucleolar antigens with mol. wts 27,000; 29,000; 30,000; 36,000; 45,000; and 46,000 were found in subcellular fractions, nuclear substructures and classes of non-histone proteins of hamster liver. The antigens with mol.wts of approx. 27,000; 29,000; and 36,000 which were absent in hamster pancreas, spleen and Kirkman--Robbins hepatoma nuclei, seem specific for liver tissue.

Abstract
Non-histone protein fraction NHCP1 of micrococcal nuclease-sensitive and nuclease-resistant chromatin from Kirkman-Robbins hepatoma and hamster liver was studied by two-dimensional electrophoresis followed by Coomassie and silver staining and by microcomplement fixation technique in the presence of antibodies elicited against NHCP1 of both tissues. Apart from many common spots several tissue specific components associated with either nuclease-sensitive or nuclease-resistant chromatin were found. The presence of tissue specific components among NHCP1 from hepatoma and liver was confirmed by immunological analysis. It was stated that these components are exclusively localized in nuclease-resistant part of chromatin from neoplastic and normal tissues thus suggesting their structural function.

Abstract
The specificity of Kirkman-Robbins hepatoma and hamster liver non-histone chromatin proteins has been studied by comparing polypeptide patterns in polyacrylamide gel electrophoresis and by their immunological activity in the complement fixation test. Non-histone proteins were separated from DNA with a polyethylene glycol-dextran mixture and fractionated by hydroxylapatite chromatography into three classes named NHCP1, NHCP2, and NHCP3. Electrophoretic analysis indicated that among the non-histone proteins of Kirkman-Robbins hepatoma and hamster liver differences mainly of a quantitative nature can be observed. However, the polypeptides with molecular weight 25 000, 31 000, 36 000, 73 000 in NHCP1; 20 000, 40 000 in NHCP2 and 20 000, 23 000, 32 000, 38 000, 44 000, 75 000, 80 000 in NHCP3 were found to be specific for hepatoma chromatin. Application of antibodies against NHCP1, NHCP2 and dehistonized chromatin of Kirkman-Robbins hepatoma revealed that the highest specificity of NHCP2 eluted from hydroxylapatite with 100 mM phosphate buffer at pH 6.8. The NHCP1 of hepatoma shares some common antigenic determinants with analogous proteins of liver. On the other hand non-histone proteins specific for hepatoma dehistonized chromatin can be localized in the NHCP3 and partially in the NHCP1 fractions.

Abstract
Micrococcal nuclease-sensitive (SP) and nuclease-resistant (PP) chromatin fractions from Kirkman-Robbins hepatoma and hamster liver were obtained. The molecular distribution of three non-histone proteins (NHCP1, NHCP2 and NHCP3), histones, and chromatin-bound protease activity between SP and PP fractions of both tissues was compared. Differences, mainly of quantitative nature, among non-histone proteins of neoplastic and normal tissue were observed. Moreover, it was found that polypeptides with mol. wt 81 000 (NHCP1), 39 000 (NHCP2) and 21 000, 35 000, 37 000 (NHCP1), 70 000, 112 000, 141 000, 157 000 (NHCP2), 30 000-33 000 (NHCP3) were associated only with the nuclease-sensitive part of chromatin of hepatoma and normal tissue, respectively. A major difference in histone composition of hamster hepatoma and liver concerns histones H2A and H1. Furthermore, an enrichment of high mobility group proteins as well as other soluble non-histone proteins in an acid extract of the SP fraction was observed. Apparently chromatin-bound protease activity can be found in both fractions of chromatin.

Abstract
Hamster liver nuclei were fractionated by digestion with micrococcal nuclease into nuclease released (SP) and nuclease resistant (PP) fractions varying in chemical composition and transcriptional activity. Electrophoretic analysis of histones from SP and PP showed no qualitative and quantitative differences. Apparently chromatin-bound protease activity can be found in both fractions. Nonhistone chromatin proteins isolated from SP and PP under mild conditions were fractionated by hydroxyapatite chromatography into NHCP1, NHCP2, NHCP3 and molecular heterogeneity and specificity were tested by SDS-polyacrylamide gel electrophoresis. The differences observed in nonhistone proteins are mainly of quantitative nature, however some specific polypeptides for SP and PP are observed.
