Abstract
INTRODUCTION Patient safety in long-term care is becoming an increasingly popular subject in the scientific literature. Organizational problems such as shortages of medical staff, insufficient numbers of facilities or underfunding increase the risk of adverse events, and aging populations in many countries suggests that these problems will become more and more serious with each passing year. The objective of the study is to identify interventions that can contribute to increasing patient safety in long-term care facilities. METHOD A systematic review of secondary studies was conducted in accordance with the Cochrane Collaboration guidelines. Searches were conducted in Medline (via PubMed), Embase (via OVID) and Cochrane Library. The quality of the included studies was assessed using AMSTAR2. RESULTS Ultimately, 10 studies were included in the analysis. They concerned three main areas: promoting safety culture, reducing the level of occupational stress and burnout, and increasing the safety of medication use. Promising methods that have an impact on increasing patient safety include: preventing occupational burnout of medical staff, e.g., by using mindfulness-based interventions; preventing incidents resulting from improper administration of medications, e.g., by using structured methods of patient transfer; and the use of information technology that is more effective than the classic (paper) method or preventing nosocomial infections, e.g., through programs to improve the quality of care in institutions and the implementation of an effective infection control system. CONCLUSIONS Taking into account the scientific evidence found and the guidelines of institutions dealing with patient safety, it is necessary for each long-term care facility to individually implement interventions aimed at continuous improvement of the quality of care and patient safety culture at the level of medical staff and management staff.

Abstract
Cell therapies are extensively tested to restore heart function after myocardial infarction (MI). Survival of any cell type after intracardiac administration, however, may be limited due to unfavorable conditions of damaged tissue. Therefore, the aim of this study was to evaluate the therapeutic effect of adipose-derived stromal cells (ADSCs) and human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) overexpressing either the proangiogenic SDF-1α or anti-inflammatory heme oxygenase-1 (HO-1) in a murine model of MI. ADSCs and hiPSCs were transduced with lentiviral vectors encoding luciferase (Luc), GFP and either HO-1 or SDF-1α. hiPSCs were then differentiated to hiPSC-CMs using small molecules modulating the WNT pathway. Genetically modified ADSCs were firstly administered via intracardiac injection after MI induction in Nude mice. Next, ADSCs-Luc-GFP and genetically modified hiPSC-CMs were injected into the hearts of the more receptive NOD/SCID strain to compare the therapeutic effect of both cell types. Ultrasonography, performed on days 7, 14, 28 and 42, revealed a significant decrease of left ventricular ejection fraction (LVEF) in all MI-induced groups. No improvement of LVEF was observed in ADSC-treated Nude and NOD/SCID mice. In contrast, administration of hiPSC-CMs resulted in a substantial increase of LVEF, occurring between 28 and 42 days after MI, and decreased fibrosis, regardless of genetic modification. Importantly, bioluminescence analysis, as well as immunofluorescent staining, confirmed the presence of hiPSC-CMs in murine tissue. Interestingly, the luminescence signal was strongest in hearts treated with hiPSC-CMs overexpressing HO-1. Performed experiments demonstrate that hiPSC-CMs, unlike ADSCs, are effective in improving heart function after MI. Additionally, long-term evaluation of heart function seems to be crucial for proper assessment of the effect of cell administration.

Abstract
Despite on-going medical advances, ovarian cancer survival rates have stagnated. In order to improve IP delivery of platinum-based antineoplastics, we aimed to develop a sustained drug delivery system for carboplatin (CPt). Toward this aim, we pursued a double emulsion process for obtaining CPt-loaded microcapsules composed of poly(ethylene terephthalate-ethylene dilinoleate) (PET-DLA) copolymer. We were able to obtain PET-DLA microspheres in the targeted size range of 10–25 µm (median: 18.5 µm), to reduce intraperitoneal clearance by phagocytosis and lymphoid transit. Empty microspheres showed the lack of toxicity in vitro. The double emulsion process yielded 2.5% w/w CPt loading and obtained microcapsules exhibited sustained (>20 day) zero-order release. The encapsulated CPt was confirmed to be bioavailable, as the microcapsules demonstrated efficacy against human ovarian adenocarcinoma (SK-OV-3) cells in vitro. Following intraperitoneal injection in mice, we did not observe adhesions, only mild, clinically-insignificant, local inflammatory response. Tissue platinum levels, monitored over 14 days using atomic absorption spectroscopy, revealed low burst and reduced systemic uptake (plasma, kidney), as compared to neat carboplatin injection. Overall, the results demonstrate the potential of the developed microencapsulation system for long-term intraperitoneal sustained release of carboplatin for the treatment of ovarian cancer.

Abstract
The mechanisms of plant cell dedifferentiation and the acquisition of totipotency are poorly understood. One of the methods to induce the dedifferentiation process in plant cells is simple and requires the removal of the cell wall. After cell wall removal in protoplasts, large-scale chromatin decondensation is observed (Tessadori et al. in J Cell Sci 120:1200-1208, 2007). Here, we show that in Arabidopsis thaliana protoplasts, despite chromatin decondensation, RNA polymerase II transcriptional activity is reduced. The subsequent investigated stages displayed a clear decrease in the quantity of 25S ribosomal RNA (rRNA) first and then poly(A+) RNA, particularly in the cytoplasm. Therefore, the reduced transcription activity and the removal of these RNA transcripts from the cytoplasm is a crucial process in obtaining totipotency in plant cells. After the cytoplasm cleaning of transcripts derived from mesophyll cells, we observed the resynthesis of these RNAs. An increase in the amount of examined molecules to a level similar to that in differentiated mesophyll cells precedes the divisions of already undifferentiated cells. In this work, we show changes in RNA polymerase II transcription dynamics and the quantity of poly(A+) RNA and 25S rRNA during dedifferentiation and re-entry into the cell cycle.

Abstract
Mesenchymal stromal cells (MSCs) have been among the most intensively studied cells in recent years. Lack of specific unique markers for these cells makes it difficult to distinguish MSCs from other types of cells, such as fibroblasts or pericytes. MSCs are a mixture of morphologically different cells with expression of various cellular markers, with varying degrees of differentiation, as well as varying proliferation capacities. The majority of phenotypic features of these cells have been identified through cell culture. One of their basic features is the capacity to differentiate into three cell lines: osteoblasts, adipocytes and chondroblasts. Under in vivo conditions, MSCs form an important functional element of the hematopoietic stem cell niche. Residing within the blood vessel wall, MSCs assist in its formation and functioning. MSCs release anti‑apoptotic and pro‑angiogenic factors, as well as agents that stimulate cell proliferation and also immunostimulating factors. In this study, we focused in particular on therapeutic strategies employing MSCs to improve the performance of the infarcted heart as well as on their involvement in the repair of hard-to-heal wounds. Thanks to the released anti-inflammatory agents, MSCs can inhibit inflammatory reactions. Owing to cytokines and growth factors they can also stimulate regeneration of damaged tissues and organs. The therapeutic effect that follows MSCs administration is linked to their paracrine activity.

Abstract
According to literature data, self-renewing, multipotent, and clonogenic cardiac c-Kit+ progenitor cells occur within human myocardium. The aim of this study was to isolate and characterize c-Kit+ progenitor cells from explanted human hearts. Experimental material was obtained from 19 adult and 7 pediatric patients. Successful isolation and culture was achieved for 95 samples (84.1 %) derived from five different regions of the heart: right and left ventricles, atrium, intraventricular septum, and apex. The average percentage of c-Kit+ cells, as assessed by FACS, ranged between 0.7 and 0.9 %. In contrast to published data we do not observed statistically significant differences in the number of c-Kit+ cells between disease-specific groups, parts of the heart or sexes. Nevertheless, c-Kit+ cells were present in significant numbers (11–24 %) in samples derived from three explanted pediatric hearts. c-Kit+ cells were also positive for CD105 and a majority of them was positive for CD31 and CD34 (83.7 ± 8.6 and 75.7 ± 11.4 %, respectively). Immunohistochemical analysis of the heart tissue revealed that most cells possessing the c-Kit antigen were also positive for tryptase, a specific mast cell marker. However, flow cytometry analysis has shown cultured c-Kit+ cells to be negative for hematopoietic marker CD45 and mast cell marker CD33. Isolated c-Kit+ cells display mesenchymal stem cell features and are thought to differentiate into endothelial cells.

Abstract
BACKGROUND The matrix metalloproteinases (MMPs) and their tissue inhibitor of metalloproteinases (TIMPs) can decompose extracellular matrix (ECM) components and brake down basement membranes and, thus, promote tumor local invasion and metastasis. METHODS We studied 41 patients with squamous cell carcinoma (SCC) of the oropharynx who underwent surgical treatment. Material was diagnosed by routine procedure and examined by immunohistochemical analysis and dot blot technique. We searched for correlations between expressions of MMPs, such as MMP-2 and MMP-9 and their tissue inhibitors TIMP-1 and TIMP-2 and treatment outcome. RESULTS We found cytoplasmic expression of analyzed proteins, both in cancer cells and tumor stroma. The expression of analyzed antigens was higher in patients with lymph node metastases comparing patients without lymph node involvement. CONCLUSION Our data suggest that microenvironment changes are one of key factors in tumor progression. Divergent expression of MMPs and their inhibitors might be used as prognostic factor of oropharyngeal carcinoma progression.

Abstract
Myocardial infarction is underoxygenation-driven limited necrosis of heart tissues which results in elimination of ca. 0.5 to 1 billion spontaneously contracting cardiomyocytes (CM). Since the ability of human heart to regenerate is limited, efforts have been undertaken to increase the number of cardiomyocytes in post-infarction myocardium. Theoretically, such proposals might involve transplantation of 1) skeletal myoblasts and cardiomyocytes, or 2) progenitor/stem cells, theoretically capable of differentiating into cardiomyocytes, or 3) pluripotent cells such as embryonal stem cells (ESC) and induced pluripotent stem cells (iPSC) differentiating into cardiomyocytes. The efforts to increase CM could also involve 4) in situ reprogramming of fibroblasts into active cardiomyocyte-like cells, or 5) stimulating in situ proliferation of cardiomyocytes using pharmacological agents. Only three proposals merit closer scrutiny (2, 4 and 5). However, preclinical and clinical data have demonstrated weak ability of progenitor cells to differentiate (proposal 2). Nevertheless, transplanted cell-induced paracrine effects accompanying such therapy do improve functioning of the damaged heart muscle. The proposals that would permit the number of CM to be increased include in situ reprogramming of fibroblasts into active cardiomyocytes (proposal 4), as well as in situ stimulation of quiescent cardiomyocytes' proliferation (proposal 5). It appears that an optimized therapeutic solution (increasing left ventricular ejection fraction and decreasing the post-infarct scar) might combine agents stimulating paracrine effects and reprogramming of fibroblasts.

Abstract
The goal of our study was to evaluate whether private alleles can be defined in microsatellite markers for the breeds under investigation; to evaluate if these private alleles distinguish chicken chimera when using different tissues; to trace them back to the donor: Green-Legged Partridgelike and recipient: White Leghorn chicken breeds, and further on, to estimate the level of chimerism in each tissue. Private and common alleles were defined for donor and recipient chicken breeds in 3 loci. The rate of chimerism was defined based on private alleles present in liver, heart, breast muscle, femoral muscle and gonads. The highest rate of chimerism was observed in liver. A lower rate of chimersim was observed in gonads, and femoral muscle, and finally the lowest rate of chimerism was observed in breast muscle and heart.

Abstract
The aim of this study was to investigate the activity of antioxidant enzymes in the blood of White Stork Ciconia ciconia chicks (aged 19-54 days) in Poland in 2006. We took under consideration superoxide dismutase (SOD), catalase (CAT), ceruloplasmine (CP), glutathione peroxidase (GPx), glutathione reductase (GR) and the content of thiobarbituric acid-reactive substances (malondialdehyde) in polluted (copper manufacture), suburban areas, at the Odra meadows, and at swamps near Baltic Sea in the Pomeranian region. We examined the levels of Na, K, Ca, Mg, Fe, Zn, Cu, Mn, Co, Cd, and Pb and compared ecophysiological determinations for developing storks. Blood samples of wing venous were collected from 91 chicks from 33 nests. The degree of activity of antioxidant enzymes studied has been different in White Stork chicks' blood from Poland regions, as a rule. We have stated a relatively high level of CAT, GPx, SOD, and GR activity and malondialdehyde (MDA) content in chicks from polluted areas. However, relative value for GR in storks from Odra meadows was considerably higher (about 112 nmol NADPH(2)/min ml) than those in chicks from other environments (56-84 nmol on average). Relatively high levels of CAT, CP, and GPx (2.7 mkM/min l, 22.2 mg/l, and 3.8 nmol GSH/min ml, respectively) were also stated in chicks nested in swamps near Baltic Sea. Simultaneously, we have stated differences (p<0.02-p<0.001) in the level of elements (besides Ca) in blood of young storks from the studied areas. We found a high level of toxic metals, e.g. Cd, either from swamps near Baltic Sea (2.7 mg/kg) or from Głogów smelter (2.2mg/kg), whilst Pb concentration was high in chicks from Głogów (7.2 mg/kg). Cd and Pb levels in blood of chicks were different in individuals from each region (p<0.001). Birds from a smelter have the highest level of these elements, whereas the lowest one was stated in chicks from Odra meadows (Cd: 1.45, Pb: 0.84 mg/kg). Thus, Cd could be a useful marker of response for polluted stress. We also observed a relatively high level of Mg in chicks from both Pomeranian (7000 mg/kg) and polluted (about 6000 mg/kg) areas. Potassium, zinc, and cobalt levels were highest in chicks from suburbs (4.65, 10.1, and 2.7 mg/kg, respectively) and polluted regions (3.8, 9.7, and 5.6 mg/kg, respectively), whilst Cu and Mn were highest in those from polluted (10.9 and 47.6 mg/kg, respectively) and Pomeranian regions (11 and 42.2 mg/kg, respectively). Concentrations of Na, K, and Ca in chicks from Głogów smelter (143.2, 3.8, and 115.9 mg/kg, respectively) were often similar to those from Odra meadows (147.8, 3.6, and 112.5 mg/kg, respectively). This was probably due to a similar degree of homeostatic regulations of an organism. The levels of Mg, Fe, Zn, and Cu were often different (p<0.02-p<0.001) in the blood of White Stork chicks from the studied areas. Co, Pb, and Cd levels were higher (p<0.001) in chicks from Głogów smelter than in those from Odra meadows. It is evidence for importance of anthropopression, which influenced the course of biogeochemical processes and the bioaccumulation of toxic metals locally. This takes place also in chicks from swamps near Baltic Sea, in which the level of Cd was high (2.7 mg/kg); so we can state the high intensity of intoxication in this region. We can conclude that the use of hematological research assesses the condition of birds and might give a positive association with miscellaneous environmental loads. The high concentration of toxic heavy metals involved greater intensity of antioxidant enzymes' activity. Environmental intoxication causes an increase of lipoperoxidation intensity in growing chicks and changes the response of their immunological system.

Abstract
AbstractTelechelic vinyl oligomers terminated with hydroxyl groups were prepared by free radical copolymerization of styrene (S) and acrylonitrile (AN), initiated by azoester-2,2’-azobis[2-methyl-ω-hydroxy-oligo(oxyethylene) propionate] [AIB-OOE(400)], carried out in N,N-dimethylformamide. The reactivity ratios rS=0,225 and rAN=0,722 for styrene and acrylonitrile, respectively, were evaluated by Kelen-Tüdős method. The glass transition temperatures (Tg) of the copolymers were determined by differential scanning calorimetry. Tg values varied with the copolymer composition in the range of 60-82 °C and the maximum Tg value was obtained for copolymer with 60 mol% AN.

Abstract
Arabinogalactan proteins (AGPs) represent a class of proteoglycans implicated in the development and differentiation of cells and tissues both in planta and in vitro. Here we report that AGP-rich extracts isolated from media of embryogenic and non-embryogenic suspension cultures of sugar beet (Beta vulgaris L.) are able to enhance the organogenesis of guard protoplast-derived callus and to increase the number of shoots formed, in comparison to control cultures. Immunocytochemical detection of carbohydrate antigens in the extracts revealed the presence of epitopes that typify both AGP and pectin, the latter being frequently bound to AGPs or, in some cases, even contributing to the polysaccharide structure of proteoglycan molecules. The most abundant epitopes proved to be those recognized by the JIM13, LM2, and MAC207 antibodies, whereas some others could be found only in relatively small or trace amounts--these included epitopes recognized by JIM16, JIM5, and LM6. Surprisingly, the JIM4- and JIM8-binding epitopes that are expressed in the course of in vitro morphogenetic processes of many species could not be detected at all in sugar beet AGPs. This is the first report of the improvement of sugar beet protoplast-derived callus organogenesis by exogenous AGP-rich extracts, an achievement that will have great impact on the biotechnological applications of protoplast technology in this species.

Abstract
We are presenting the pattern of distribution of several carbohydrate epitopes, which constitute an important component of cell walls, within the anthers and pistils of a monocot grass species, perennial ryegrass (Lolium perenne L.). The results of immunocytochemical studies revealed that the flower organs are rich in (1-->3, 1-->4)-beta-D-glucans and possess surprisingly high amounts of methylesterified pectic domains that bind JIM7 antibody and pectin side chains rich in (1-->4)-beta-D-galactose residues which react with LM5 antibody. The presence of arabinogalactan protein epitopes binding JIM13 is restricted to microspores and ovule integuments. The results are discussed in terms of possible functions of cell wall polysaccharides and arabinogalactan proteins in the differentiation of flower organs.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) infection is one of the most common chronic infections in humans. While a causative relationship between H. pylori infection and several gastrointestinal disorders has been well established, the association between this condition and the development of atherosclerosis and coronary artery diseases (CAD) is less clear. AIM To examine the relationship between H. pylori infection and endothelial function in patients with acute coronary syndrome (ACS) without ST segment elevation. METHODS The study group consisted of 31 patients (17 males aged 38-78 years and 14 females aged 45-80 years) with ACS and without ST segment elevation in whom we measured antibodies to H. pylori and haemostatic factors indicating endothelial function, such as von Willebrand factor (vWF), thrombomodulin (TM), tissue plasmin activator (tPA:Ag), tPA inhibitor (PAI-1:Ag) and fibrinogen. RESULTS The proportion of patients with H. pylori seropositivity was 93.5%. No significant relationship between parameters of endothelial function and IgG antibodies to H. pylori were found. There was a significant association between antibodies to p54 protein and vWF (p=0.027) and between antibodies to p33 protein and PAI:Ag concentration (p=0.019). CONCLUSIONS These results suggest that the type of H. pylori antigens and antibodies to these antigens rather than the presence of IgG antibodies to H. pylori may play a role in the development of CAD.

Abstract
BACKGROUND Various chronic infections, including Chlamydia pneumoniae (C. pneumoniae), are regarded as one of the possible factors which initiates, progresses and exacerbates atherosclerotic process. The relationship between C. pneumoniae infection and haemostatic factors which also may promote atherosclerosis, has not yet been established. AIM To assess the relationship between C. pneumoniae-specific IgA and IgG serum antibodies and haemostatic factors in patients with acute coronary syndrome (ACS). METHODS The study group consisted of 31 patients (17 males, mean age 62 years, and 14 females, mean age 60.6 years) with ACS and without ST segment elevation in whom antibodies to C. pneumoniae and such haemostatic factors as von Willebrand factor (vWF), thrombomodulin (TM), tissue plasmin activator (tPA), tPA inhibitor (PAI-1) and fibrinogen were measured. RESULTS The proportion of patients with C. pneumoniae seropositivity was 35.4% in our study which is lower than that reported in literature. No significant relationship between vWF, TM, tPA and PAI-1 levels, and C. pneumoniae infection was found whereas a significant (p=0.05) relationship between C. pneumoniae-specific IgG antibodies and fibrinogen level was detected. CONCLUSIONS Excluding fibrinogen, the presence of antibodies to C. pneumoniae is not associated with increased levels of haemostatic factors in patients with ACS without ST segment elevation.

Abstract
BACKGROUND Thrombomodulin (TM) a membrane receptor for thrombin generated in blood in vivo, is present on the surface of vascular endothelium cells. The aim of our work was the determination of thrombomodulin in the blood of patients with unstable angina pectoris. MATERIAL AND METHODS In the study took part 87 patients with unstable angina pectoris (40 women and 47 men) at age 41-79 years. Thrombomodulin was determined in citrated blood plasma with the use of enzyme immunoassay ELISA with the diagnostic kit manufactured by American Diagnostica. RESULTS Statistically significant higher thrombomodulin concentration (sTM) was found in the patients when compared with the values recorded in control group. Elevated sTM levels depended on patients age and they were significantly higher in patients over 50 years old. There were no statistically significant differences with respect to patients gender and coexistent risk factors such as arterial hypertension, diabetes or smoking, but significantly higher sTM concentration was observed in patients with high serum cholesterol level. CONCLUSION Elevated sTM concentrations result from the damage to vascular endothelium cells by the atheromatous process manifested in unstable angina pectoris.

Abstract
In patients with bladder carcinoma a shorter ELT, and increased concentrations of EDP and t-PA were observed. These indicate on fibrinolysis activation caused by the released of t-PA. The increased fibrinolytic activity can be a cause of hemorrhagic complication occurring sometimes in bladder carcinoma. We observed much stronger activation of fibrinolysis in patients with an advanced bladder carcinoma.

Abstract
In urine of 25 patients with bladder carcinoma the antigen of tissue type plasminogen activator (t-PA) was assessed. The level of t-PA was much higher in patients with bladder carcinoma in comparison with a control group. We also analyzed the level of t-PA between patients with superficial and invasive bladder carcinoma the level of t-PA was higher. In conclusion, there is t-PA in urine of patients with bladder carcinoma and its level is correlated with staging of neoplasm.

Abstract
The activity of antithrombin III (AT III) in the blood of patients with bladder carcinoma was examined. It was shown an increase of AT III activity in comparison with control group. The changes of AT III activity in the blood of patients with bladder carcinoma can be the symptoms of an increased risk of haemorrhagic or thromboembolic complications.

Abstract
The activity of antithrombin III (AT III) in the blood of 20 patients with renal carcinoma was examined. An increase of AT III activity in comparison with control group was observed. The increase of AT III activity in the blood of the patients with renal carcinoma can be as a result of compensatory mechanism safing these patients before thromboembolic complication. The measurement of AT III in renal carcinoma can be a prognostic symptom of haemorrhagic and thromboembolic complications.
