Abstract
AIMS Gestational diabetes mellitus (GDM) is the most common type of hyperglycaemia in pregnancy. GDM is a risk factor of adverse perinatal outcomes, with the incidence rate increasing proportionally to the level of maternal dysglycaemia. Therefore, glycaemic control plays an important role in management of GDM. The aim of this study was to assess the efficacy of flash glucose monitoring (FGM) in GDM. MATERIALS AND METHODS This was a non-blinded, randomised controlled trial, that recruited 100 pregnant women diagnosed with GDM between 24 and 28 weeks of gestation at the 1st Department of Obstetrics and Gynaecology, Medical University of Warsaw. After meeting the inclusion criteria patients were randomly allocated to the study group (FGM, n = 50) or control group (self-monitoring of blood glucose-SMBG, n = 50). Clinical and laboratory results were assessed at four follow-up visits. The primary outcome was mean fasting and postprandial glycaemia. The secondary outcomes were perinatal outcomes. RESULTS There was no significant difference in mean glycaemia between the groups (p = 0.437) Compared to the control group, the study group significantly reduced their fasting (p = 0.027) and postprandial glycaemia (p = 0.034) during the first 4 weeks following GDM diagnosis, with no significant difference in progression to insulin therapy (OR 1.09, 95% CI 0.47-2.57). Incidence of fetal macrosomia was significantly higher in SMBG as compared to FGM group (OR 5.63, 95% CI 1.16-27.22). CONCLUSIONS Study results indicate that FGM has an impact on glycaemic control, dietary habits and incidence of fetal macrosomia in patients with GDM. Trial registration clinicaltrials.gov ID: NCT04422821.

Abstract
Hyperglycaemia in pregnancy is one of the most common complications of pregnancy and is generally diagnosed as gestational diabetes mellitus (GDM). Nevertheless, clinical symptoms of hyperglycaemia in pregnancy in some cases do not match the clinical manifestations of GDM. It is suspected that 1-2 % of women diagnosed with GDM are misdiagnosed maturity-onset diabetes of the young (MODY). MODY often has a subclinical course; thus, it is challenging for clinicians to aptly diagnose monogenic diabetes in pregnancy. Proper diagnosis is crucial for the effective treatment of hyperglycaemia in pregnancy. Many studies revealed that misdiagnosis of MODY increases the rate of complications for both mother and fetus. This literature review reports the current knowledge regarding diagnosis, treatment, and complications of the most common types of MODY in pregnancy.

Abstract
Autism spectrum disorders (ASDs) are multifactorial and complex neurodevelopmental conditions usually diagnosed in the early childhood. The etiology of ASDs is commonly described as a genetic predisposition combined with an environmental impact. As a result of broadening of the diagnostic criteria the prevalence of ASDs has been increasing worldwide and the search for the modifiable factors is still on-going. Epidural analgesia (ELA) provides effective pain relief during labor and is currently the most preferred method of anesthesia during the delivery. The safety of the procedure is well-discussed and documented; nonetheless, in 2020 a single population-based study indicated an association between the use of ELA during labor and newborn risk of ASD development, which led to widespread concern. To explore the possible association between the ELA and ASD occurrence in the offspring several studies in different countries have been conducted to date. In this review we aimed to summarize the current state of knowledge concerning the association between the use of epidural analgesia during labor and risk of ASD. In conclusion, the literature review indicates that there is no significant association.

Abstract
Background In utero limb ischemia is a rare complication of the monochorionic twin pregnancies complicated with twin to twin transfusion syndrome (TTTS). The condition is more often seen in recipient twins. There are few theories of the pathogenesis including in utero venous thromboembolism, but the cause remains unclear. However, limb ischemia is thought to be unrelated with any prenatal intervention. Case Presentation We present a case of a monochorionic twin pregnancy complicated with TTTS admitted to the Clinic for selective fetoscopic laser photocoagulation. The invasive procedure failed due to poor visibility. In the following weeks of pregnancy, amnioreduction procedures were performed. At 28 weeks of gestation due to twin anemia-polycythemia sequence diagnosis the patient was qualified for cesarean section. Postnatally, the donor twin was diagnosed with lower right limb ischemic necrosis. The extremity was amputated 2 days later with an uncomplicated recovery. After speculations of the potential pathogeneses it was suggested that the ischemic limb occurred as a complication of the main condition – TTTS. Conclusions In literature, there have been no cases reported of TTTS stage I complicated with donor twin limb ischemia. The actual cause of the in utero limb ischemic necrosis in monochorionic twins remains unknown. Nevertheless, increased attention to the potential complication after failed invasive procedures or conservative treatment should be required.

Abstract
Aims/Introduction The aim of the present study was to evaluate the placental expression of glucose transporters GLUT‐1, GLUT‐3, GLUT‐8 and GLUT‐12 in term pregnancies complicated by well‐controlled gestational (GDM) and type 1 pregestational diabetes mellitus (PGDM). Materials and Methods A total of 103 placental samples were obtained from patients diagnosed with GDM (n = 60), PGDM (n = 20) and a non‐diabetic control group (n = 23). Computer‐assisted quantitative morphometry of stained placental sections was performed to determine the expression of selected GLUT proteins. Results Immunohistochemical techniques used for the identification of GLUT‐1, GLUT‐3, GLUT‐8 and GLUT‐12 revealed the presence of all glucose transporters in the placental tissue. Morphometric evaluation performed for the vascular density‐matched placental samples demonstrated a significant increase in the expression of GLUT‐1 protein in patients with PGDM as compared to GDM and control groups (P < 0.05). With regard to the expression of the other GLUT isoforms, no statistically significant differences were observed between patients from the diabetic and control populations. Positive correlations between fetal birthweight and the expression of GLUT‐1 protein in the PGDM group (rho = 0.463, P < 0.05) and GLUT‐12 in the control group (rho = 0.481, P < 0.05) were noted. Conclusions In term pregnancies complicated by well‐controlled GDM/PGDM, expression of transporters GLUT‐3, GLUT‐8 and GLUT‐12 in the placenta remains unaffected. Increased expression of GLUT‐1 among women with type 1 PGDM might contribute to a higher rate of macrosomic fetuses in this population.

Abstract
BACKGROUND Ursodeoxycholic acid is commonly used to treat intrahepatic cholestasis of pregnancy, yet its largest trial detected minimal benefit for a composite outcome (stillbirth, preterm birth, and neonatal unit admission). We aimed to examine whether ursodeoxycholic acid affects specific adverse perinatal outcomes. METHODS In this systematic review and individual participant data meta-analysis, we searched PubMed, Web of Science, Embase, MEDLINE, CINAHL, Global Health, MIDIRS, and Cochrane without language restrictions for relevant articles published between database inception, and Jan 1, 2020, using search terms referencing intrahepatic cholestasis of pregnancy, ursodeoxycholic acid, and perinatal outcomes. Eligible studies had 30 or more study participants and reported on at least one individual with intrahepatic cholestasis of pregnancy and bile acid concentrations of 40 μmol/L or more. We also included two unpublished cohort studies. Individual participant data were collected from the authors of selected studies. The primary outcome was the prevalence of stillbirth, for which we anticipated there would be insufficient data to achieve statistical power. Therefore, we included a composite of stillbirth and preterm birth as a main secondary outcome. A mixed-effects meta-analysis was done using multi-level modelling and adjusting for bile acid concentration, parity, and multifetal pregnancy. Individual participant data analyses were done for all studies and in different subgroups, which were produced by limiting analyses to randomised controlled trials only, singleton pregnancies only, or two-arm studies only. This study is registered with PROSPERO, CRD42019131495. FINDINGS The authors of the 85 studies fulfilling our inclusion criteria were contacted. Individual participant data from 6974 women in 34 studies were included in the meta-analysis, of whom 4726 (67·8%) took ursodeoxycholic acid. Stillbirth occurred in 35 (0·7%) of 5097 fetuses among women with intrahepatic cholestasis of pregnancy treated with ursodeoxycholic acid and in 12 (0·6%) of 2038 fetuses among women with intrahepatic cholestasis of pregnancy not treated with ursodeoxycholic acid (adjusted odds ratio [aOR] 1·04, 95% CI 0·35-3·07; p=0·95). Ursodeoxycholic acid treatment also had no effect on the prevalence of stillbirth when considering only randomised controlled trials (aOR 0·29, 95% CI 0·04-2·42; p=0·25). Ursodeoxycholic acid treatment had no effect on the prevalence of the composite outcome in all studies (aOR 1·28, 95% CI 0·86-1·91; p=0·22), but was associated with a reduced composite outcome when considering only randomised controlled trials (0·60, 0·39-0·91; p=0·016). INTERPRETATION Ursodeoxycholic acid treatment had no significant effect on the prevalence of stillbirth in women with intrahepatic cholestasis of pregnancy, but our analysis was probably limited by the low overall event rate. However, when considering only randomised controlled trials, ursodeoxycholic acid was associated with a reduction in stillbirth in combination with preterm birth, providing evidence for the clinical benefit of antenatal ursodeoxycholic acid treatment.

Abstract
INTRODUCTION Gestational diabetes mellitus (GDM) is a glucose intolerance occurring in 3%-10% of pregnant women and being a risk factor for multiple maternal and fetal complications. The risk of perinatal complications is proportional to the level of maternal hyperglycaemia. Proper glycaemic control is therefore one of the key elements of GDM therapy. Until recently, determination of blood glucose concentration was performed using glucose meters, which involved multiple fingerpricks. Nowadays, due to the flash glucose monitoring (FGM) availability, it is possible to collect measurements at any time without routine puncturing. The aim of the presented study is to assess the impact of FGM on the efficacy of treatment in population of patients diagnosed with GDM. METHODS AND ANALYSIS This is a prospective, randomised study, that will recruit 100 women at 24-28 weeks of gestation at the 1st Department of Obstetrics and Gynecology, Medical University of Warsaw, Poland. Women diagnosed with GDM, who will meet the inclusion criteria, will be individually randomised to the FGM or self-monitoring of blood glucose groups. Further on, clinical and laboratory results of the mother and their newborns will be collected for analysis during the course of pregnancy. Primary outcome is mean glycaemia result in each group after 1 month analysis and percentage of results in the target glycaemic range. The secondary objectives will be to compare the two groups for maternal and neonatal outcomes in conjunction with long-term glycaemic control using blood glycated haemoglobin and fructosamine serum concentrations. ETHICS AND DISSEMINATION The study is exempt from regional ethics review due to its nature of quality improvement in patient care. The study has been approved by the Bioethics Committee at the Medical University of Warsaw and the patient privacy protection boards governing over the recruitment sites. Results of the study will be presented in peer-reviewed journals and at conferences. TRIAL REGISTRATION NUMBER NCT04422821.

Abstract
BACKGROUND The aim of the study was to evaluate the ultrasound-derived measurements of the fetal soft-tissue, heart, liver and umbilical cord in pregnancies complicated by gestational (GDM) and type 1 diabetes mellitus (T1DM), and further to assess their applicability in the estimation of the fetal birth-weight and prediction of fetal macrosomia. METHODS Measurements were obtained from diet-controlled GDM (GDMG1) (n = 40), insulin-controlled GDM (GDMG2) (n = 40), T1DM (n = 24) and healthy control (n = 40) patients. The following parameters were selected for analysis: fetal sub-scapular fat mass (SSFM), abdominal fat mass (AFM), mid-thigh fat/lean mass (MTFM/MTLM) and inter-ventricular septum (IVS) thicknesses, heart and thorax circumference and area (HeC/HeA; ThC/ThA), liver length (LL), umbilical cord/vein/arteries circumference and area (UmC/UmA; UvC/UvA; UaC/UaA) together with total umbilical vessels (UveA) and Wharton's jelly area (WjA). Regression models were created in order to assess the contribution of selected parameters to fetal birth-weight (FBW) and risk of fetal macrosomia. RESULTS Measurements of the fetal SSFM, AFM, MTFM, MTFM/MTLM ratio, HeC, HeA, IVS, LL, UmC, UmA, UaC, UaA, UveA and WjA were significantly increased among patients with GDMG2/T1DM as compared to GDMG1 and/or control groups (p < .05). The regression analysis revealed that maternal height as well as fetal biparietal diameter, abdominal circumference (AC), AFM and LL measurements were independent predictors of the FBW (p < .05). In addition, increase in the fetal AFM, AC and femur length (FL) was associated with a significant risk of fetal macrosomia occurrence (p < .05). The equation developed for the FBW estimation [FBW(g) = - 2254,942 + 17,204 * FL (mm) + 105,531 * AC (cm) + 131,347 * AFM (mm)] provided significantly lower mean absolute percent error than standard formula in the sub-group of women with T1DM (5.7% vs 9.4%, p < .05). Moreover, new equation including AC, FL and AFM parameters yielded sensitivity of 93.8%, specificity 77.7%, positive predictive value 54.5% and negative predictive value of 97.8% in the prediction of fetal macrosomia. CONCLUSIONS Ultrasound measurements of the fetal soft tissue, heart, liver and umbilical cord are significantly increased among women with GDM treated with insulin and T1DM. In addition to standard biometric measurements, parameters, such as AFM, may find application in the management of diabetes-complicated pregnancies.

Abstract
OBJECTIVE The description of clinical manifestation of hearing problems in cleidocranial dysplasia (CCD) remains limited and incomplete, since CCD constitutes a rare congenital disorder. The study aims to provide a complex panel analysis of the auditory system in patients suffering from the disease. PATIENTS AND METHODS The study group consisted of 4 children with CCD (aged: 12-15), who underwent orthodontic treatment. A full panel analysis of their auditory systems was performed, including high-frequency audiometry and a new method of middle ear assessment - WBT (Wideband Tympanometry). RESULTS A slight conductive hearing loss was diagnosed in 3 out of 4 patients. While high frequency audiometry has shown a deterioration of hearing in 3 patients, in one case, the obtained thresholds were within the normal range. A decrease of absorbance in low frequencies has been observed in one or both ears. Only one patient has had a shift of maximum absorbance towards high frequencies in the left ear. CONCLUSIONS The presented manuscript is the first with a complete evaluation of the auditory system comprising 4 cases of children in a similar age group. All of the examined patients presented an air-bone gap indicating conductive disorders.

Abstract
OBJECTIVES Intrahepatic cholestasis of pregnancy (ICP) is a liver specific disorder affecting 0.08%-27.6% pregnant women.It is characterized by reduced expression of the primary bile acid farnesoid receptor (FXR). In recent studies, it has beenshowed that FXR has an impact on normal glucose homeostasis. Based on that it was suggested that the level of bile acidscorrelates with glucose level. The aim of the study was to evaluate the association between ICP and gestational diabetesmellitus (GDM). MATERIAL AND METHODS 102 singleton patients complicated by ICP were included to the study and divided into twogroups: non-GDM group (74 patients) and GDM group (28 patients). ICP was diagnosed based on the serum bile acidslevel > 10 μmol/L and GDM with the 75 g oral glucose tolerance test and FIGO guidelines. Demographic and clinical outcomedata (including maternal age, BMI and infant weight) and ICP and GDM biochemical markers were collected. RESULTS The incidence of GDM in ICP patients was 27.45%. 73% of women included to the study developed mild cholestasis.Lower levels of serum bile acids were correlated with GDM group. When compared mean total bilirubin level wassignificantly higher in non-GDM group. Transaminases (ALT, AST) and neonate condition including mean birth weightrevealed no significant difference between the groups. On the other hand, prevalence of large for gestational age wassignificantly higher in non-GDM group (p < 0.00001). CONCLUSIONS The incidence of ICP is higher in women with GDM.

Abstract
Polish Red cattle is one of the few indigenous breeds of European red cattle which is characterized by several desired features, such as high disease resistance, good health, longevity, good fertility, and high nutritional value of milk. Currently, Polish Red cattle population is a subject of two independent breeding programs: (i) improvement program and (ii) genetic resources conservation program. The aim of the improvement program is the genetic progress in terms of milk production and body conformation traits, while the conservation program mainly focuses on protection of the genetic resources of Polish Red cattle and preservation of the existing, original gene pool. By the analysis of FST genetic distances across genome-wide SNP panel, we detected diversifying selection signatures among these two subpopulations and indicated (among others) the significance of DGAT1 and FGF2 genes for milk production traits in these cattle. We also found that among genes being presumably under selection in terms of milk production, there are genes responsible, for example, for mammary gland development (e.g., SOSTDC1, PYGO2, MED1, and CCND1) and immune system response (e.g., IL10RA, IL12B, and IL21). The most important finding of this study is that the most pronounced genetic differences between the analyzed populations were associated with β-defensin genes (e.g., DEFB1, DEFB4A, DEFB5, DEFB7, DEFB10, DEFB13, EBD, BNBD-6, and LAP) located within so-called bovine cluster D on BTA27. The β-defensins are expressed mainly in the mammary gland and are antimicrobial peptides against the Gram-negative and Gram-positive bacteria, viruses, and other unicellular parasites. This suggests that antimicrobial resistance of mammary gland is of high importance during selection towards increased milk production and that genes responsible for this process are selected together with increasing levels of productivity.

Abstract
High-fat diet, exposure to saturated fatty acids, or the presence of adipocytes in myoblast microenvironment affects skeletal muscle growth and function. The aim of the present study was to investigate the effect of palmitate supplementation on transcriptomic profile of mouse C2C12 myoblasts. Global gene expression was evaluated using whole mouse genome oligonucleotide microarrays, and the results were validated through qPCR. A total of 4047 genes were identified as differentially expressed, including 3492 downregulated and 555 upregulated genes, during a 48-h exposure to palmitate (0.1 mmol/l). Functional classification showed the involvement of these genes in several processes which regulate cell growth. In conclusion, the addition of palmitate modifies the expression of genes associated with (1) myoblast responsiveness to hormones and growth factors, (2) cytokine and growth factor expression, and (3) regulation of cell-cell and cell-matrix communication. Such alterations can affect myoblast growth and differentiation; however, further studies in this field are required.

Abstract
The aim of the study was to determine the effects of platelet-activating factor (PAF) on selected quality parameters of cryopreserved bull semen with reduced sperm motility used for artificial insemination. The aim of experiment 1 was to identify the optimal concentration of the phospholipid able to preserve sperm viability. Cryopreserved semen was treated with different PAF concentrations: 1×10-5M, 1×10-6M, 1×10-7M, 1×10-8M and 1×10-9M. The experiment demonstrated that PAF at concentration 1×10-9M increased most the sperm viability parameters (motility parameters, plasma membrane integrity and mitochondrial function) after 120 min of incubation of thawed semen at 37°C. Cryopreserved bull semen with reduced sperm motility (below 70%) was supplemented with PAF in a concentration of 1×10-9M. A statistically significant increase in sperm motility, percentage of linear motile spermatozoa and VSL value was observed after 120 min incubation of sperm with 1×10-9M PAF. Sperm supplementation with PAF also had positive effects on plasma membrane integrity and percentage of spermatozoa with preserved mitochondrial transmembrane potential, but the differences were not statistically significant. The results indicated positive effects of PAF supplementation at a concentration of 1×10-9M on the selected sperm quality parameters in cryopreserved bull semen with reduced motility.

Abstract
Immunocompromised patients and patients undergoing invasive procedures are predisposed to bacterial infections, due to the possibility of micro-organism translocation from their physiological habitat. Infectious complications may occur both in the early and late post-transplantation periods. The purpose of this study was to evaluate the proportion as well as susceptibility profiles of obligatory anaerobes in the etiology of infections in patients hospitalized at transplantation wards of a large clinical hospital in Warsaw. A total of 104 strains of obligatory anaerobes derived from patients hospitalized in two transplantation clinics at a clinical hospital in Warsaw were evaluated. The strains were isolated from 87 clinical samples collected from 84 patients of two transplantation wards between 2007 and 2012. A total of 104 obligatory anaerobic bacterial strains were isolated and identified, with Gram-positive and Gram-negative bacteria constituting 60.6% and 39.4% of the isolates, respectively. Almost exclusively non-spore-forming anaerobes were detected in evaluated samples. The present study showed all isolated Gram-positive bacteria to be susceptible to ß-lactam antibiotics. Metronidazole-resistant bacteria were found among the genera Propionibacterium and Actinomyces. All Gram-negative rods were susceptible to imipenem and metronidazole. Among them, Bacteroides spp. and Parabacteroides distasonis showed resistance to penicillin G (100%). Because of their pathogenicity and altered antibiotic susceptibility profiles, the bacteria of the genera Bacteroides and Parabacteroides are of greatest clinical importance. Approximately 25% of isolates exhibit also resistance to clindamycin. Because of the growing rates of clindamycin resistance, the role of metronidazole in the treatment of Bacteroides spp. is of increasing importance.

Abstract
Glutathione-S-transferase genes (GSTs) encode enzymes that are involved in detoxification and neutralization of reactive oxygen species (ROS) in male reproductive system and play protective role during spermatogenesis. The aim of the study was to evaluate whether C/G missense mutation (rs135955605) within glutathione-S-transferase M1 (GSTM1) gene is associated with selected parameters of frozen-thawed semen in 309 Holstein-Friesian bulls. Single nucleotide substitution C/G was identified by amplification of GSTM1 gene fragment followed be digestion with restriction enzyme DdeI. Bulls with GG genotype were the most frequent (67.96%), in comparison to CC (2.59%) and GC (29.45%). Significant associations were found between GSTM1 genotypes and ATP content and total sperm motility. Bulls with GG genotype had the highest values for both traits. Rare variant C of GSTM1 was associated with significant decrease of sperm motility and ATP content. Our results demonstrate that C/G missense mutation within GSTM1 gene is involved in bull sperm quality.

Abstract
Abstract
Selected qualitative and biochemical parameters were determined in cryopreserved semen used for artificial insemination, sampled from 120 bulls reared at the Animal Breeding and Insemination Center in Bydgoszcz. The total average motility of the analyzed sperm samples was determined at 62.51%. The percentage of motile spermatozoa displaying progressive forward motility was 21.65%. Analyzed samples were characterized by a high percentage of sperm cells with a intact plasma membrane (71.21%) and active mitochondria (71.32%). High efficiency of the enzymatic antioxidant system of the evaluated sperm cells was demonstrated by high activity of CAT, GPx and SOD (494.37, 2847.83 and 5.31U/1×109 spermatozoa, respectively) values and low values of the DNA Fragmentation Index (9.32). The results of the study, obtained with the involvement of advanced analytical methods, indicate a high fertilizing capability of the analyzed sperm samples.

Abstract
The purpose of this study was to identify novel marbling-related genes by comparison of the global gene expression in semitendinosus muscle of 15-month-old Limousin (LIM), Holstein-Friesian (HF) and Hereford (HER) bulls. Muscle of LIM was lean with low intramuscular fat (IMF) content (0.53%) unlike the marbled muscles of HER and HF characterized by higher amounts of IMF (1.10 and 0.81%, respectively). The comparison of muscle transcriptional profile between marbled and lean beef revealed significant differences in expression of 144 genes, presumably involved in consecutive stages of adipose tissue development, such as preadipocyte proliferation and differentiation, adipocyte maturation, lipid filling and lipid metabolism leading to increased IMF deposition and marbling development. Correlation coefficients and regression analysis for nine of them (gadd45a, pias3, ccrn4l, diras3, pou5f1, hoxa9, atp2a2 and pim1) validated by real-time qPCR confirmed their moderate-high correlation with IMF% and explained up to 70.5% of the total variability in IMF deposition in the bulls.

Abstract
Herpes simplex virus 1 (HSV-1) establishes life-long latency in peripheral neurons, where productive replication is suppressed. To study the specific relationship between the virus and peripheral neurons that would not be affected by other cells usually present in in vivo systems, we present an in vitro model system based on primary cultures of murine neurons. This model system can be used for characterization of various virus strains and testing of cytotoxicity and inhibitory activity of acyclovir (ACV), cidofovir (CDV) and other antivirals.

Abstract
In light of the high incidence of mammary cancer in dogs and completion of the canine genome sequencing, the new possibilities of gene profiling by using DNA microarrays give hope to veterinary oncology. The cell lines isolated from mammary tumors are a valuable tool in developing and testing new pathway-specific cancer therapeutics. Differential cytometric analysis of 6 canine mammary cancer cell lines was performed. We divided cell lines into 3 groups based on their phenotype: 2 lines with high proliferative potential, 2 lines with high antiapoptotic potential, and 2 lines with high metastatic potential. DNA microarray analysis revealed common genes for cell lines of each group. We found that genes encoding the receptors for growth hormone and ghrelin are related to high proliferation rate, while ABR (active BCR-related) and TMD1 (TM2 domain containing 1) genes are related to a high antiapoptotic potential of the cancer cells. Metastatic properties of mammary cancer cells seem to be associated with elevated expression of PGP (P glycoprotein), SEMA3B (semaphorin 3B), and STIM1 (stromal interaction molecule 1).

Abstract
Metastasis is a final step in the progression of mammary gland cancer, usually leading to death. Potentially, a molecular signature of metastasis can be defined via comparison of primary tumors with their metastases. Currently, there is no data in the literature regarding the molecular portrait of metastases in dogs and only few reports regarding human cancer. This is the first report describing the transcriptomic signature of canine cancer metastatic cells. Two adenocarcinoma cell lines isolated from the canine mammary gland (CMT-W1 and CMT-W2) were compared with cell lines isolated from their lung metastases (CMT-W1M and CMT-W2M) with regards to the following cytometric parameters: cell cycle, ploidy, Bcl-2 expression, susceptibility to induced apoptosis, and transcriptomic profile. Cytometric analyses revealed significant differences in cell cycle and antiapoptotic potential between the examined cells. Using oligonucleotide microarrays, we found 104 up-regulated genes in the metastatic cell line CMT-W1M and 21 up-regulated genes in the primary CMT-W1 cell line. We also found 83 up-regulated genes in the CMT-W2M cell line and only 21 up-regulated genes in the CMT-W2 cell line. Among the up-regulated genes in both metastatic cell lines, we found 15 common genes. These differently expressed genes are involved mainly in signal transduction, cell structure and motility, nucleic acid metabolism, developmental processing, and apoptosis (GHSR, RASSF1, ARF1GAP, WDR74, SMOC2, SFRP4, DIAPH1, FSCN1, ALX4, SNX15, PLD2, WNT7B, POU6F2, NKG7, and POLR2F). Seven of them are involved in a cellular pathway dependent on ghrelin via growth hormone secretagogue receptor (GHSR). Our results suggest that this pathway may be essential for mammary cancer cells to have a metastatic potential.

Abstract
Mammary epithelial cells (MECs) are characterized by specific spatial architecture with several distinguishing features such as: polarized morphology, specialized cell-cell contacts, and attachment to an underlying basement membrane. Three dimensional (3D) basement membrane cultures provide a unique opportunity to model the architecture of epithelium in vitro. The aim of this study was to characterize the growth of bovine mammary epithelial cell line BME-UV1 in 3D culture on Matrigel and identification of differently expressed genes in bovine MECs forming polarized structures in comparison to conventional monolayer (2D) cell culture. We demonstrate that BME-UV1 cells grown on Matrigel form polarized acinar structures during 16 days of culture. A microarray study has proven that the difference in spatial architecture between MECs cultured in monolayer and 3D system is reflected by differences in transcriptomic profile. Microarray data analysis showed 40 differentially expressed genes with statistical significance (p<0.05) and characterized biological functions. Identified genes comprised of cytoskeletal proteins, extracellular matrix components, kinases such as: Rac serine/threonine kinase, SRPK, protooncogene tyrosine-protein kinase ABL1, uridine cytidine kinase and proteins with nucleic acid binding / transcription factor activity. Products of those genes are involved in processes which are known to participate in regulating mammary gland polarization and function.

Abstract
Tumor-derived cell lines are widely used as in vitro cancer models. Cell lines historically served as the primary experimental model systems for exploration of tumor cell biology and pharmacology. However, their ability to accurately reflect the phenotype and genotype of the parental histology remains questionable, given the prevalence of documented cell line-specific cytogenetic changes. Sometimes cell line studies are interpreted in the context of artifacts introduced by selection and establishment of cell lines in vitro. This complication has led to difficulties in the extrapolation of biology observed in cell lines to tumor biology in vivo. The aim of our study was to compare gene expression profiles in canine mammary tumor tissue and cell cultures derived from those tumors using cDNA microarrays. Tumors of two different origins were used; chondrosarcoma and adenocarcinoma and their primary cell cultures. It has been found that cell culture gene expression profiles closely resembled those of their corresponding in vivo tumor. In adenocarcinoma and chondrosarcoma only 6.0% and 2.7% of genes respectively, have shown significant difference in expression. In the most cases the difference concerned up-regulation of gene expression in cell lines, particularly genes involved in: protein metabolism and modification, signal transduction and nucleotide, nucleoside and nucleic acid metabolism. These experiments revealed that transcriptome of our primary cell culture corresponds to transcriptome of its parental tumor tissue and for this reason cell culture represents the reliable in vitro model for oncogenomic and pharmacogenomic studies.

Abstract
PURPOSE Calcium-phosphate disorders are a frequent finding in HD patients, and, in some cases, may cause an abnormal coronary calcification. Some of the HD patients have increased serum cTnI level without evidence of acute coronary syndrome. The aim of this study was to determine if there is a correlance between increased cTnI levels and presence of stenotic changes in coronary arteries in asymptomatic HD patients. MATERIAL AND METHODS In 13 of 119 HD patients (M:F 10:3) a coronary angiography was performed. The mean age of the patients was 53 years (33-76) and the mean HD duration was 55 months (3-156). cTnI was analyzed by AxSYM system and, subsequently, by VIDAS system. RESULTS A constant or intermittent elevation of cTnI was detected in 5 of 13 patients. In 10 of 13 pts a critical stenosis of at least 1 coronary artery was found. A critical stenosis was found in 4 of 5 cTnI (+) patients and in 6 of 8 cTnI (-) patients. An excess calcification of coronaries was observed in 7 patients, including 1 cTnI positive patient with no evidence of coronary stenosis. CONCLUSIONS 1. The elevation of cTnI in asymptomatic HD patients is observed when there is: (I) excess calcification accompanied by a critical stenosis of at least 1 coronary artery, (II) a critical stenosis of 2 or more coronaries with no evidence of calcification. 2. We suggest that excess cardiovascular calcification in HD patients may be one of the major factors responsible for the troponin release.

Abstract
Dendritic spines occupy a strategic position in the central nervous system, yet their function is still under debate. Over the past decades, many hypotheses have been put forward to explain the specific function of spines. Recently, imaging experiments have demonstrated that spines compartmentalize calcium, a role that appears necessary for input-specific forms of synaptic plasticity. In addition, it has been discovered that spine morphology is plastic over fast time scales and can be controlled by specific biochemical pathways. Also, several aspects of the spine's morphology appear to be intricately linked to its function. The authors review these recent data and incorporate them into a model for the function of dendritic spines in CNS circuits. In their proposal, spines serve to specifically connect sparse inputs and therefore minimize the wiring necessary in the CNS while maximizing connectivity. By virtue of the same design, spines isolate inputs and thus implement local learning rules. These rules appear only necessary with sparse inputs so these two functions are intimately related. Spines therefore would play a crucial circuit role, remarkably analogous to synaptic matrix elements of associative neural networks. This model highlights the economical, yet elegant, design of CNS circuits.

Abstract
Gap junctions are prevalent in every nervous system, but their role in information processing remains largely unknown. In C. elegans, the role of gap junctional communication in touch sensitivity has been demonstrated. In this animal, the entire complement of gap junctions in the nervous system is documented, therefore providing a good model for the computational investigation of circuit functions of gap junctions.We explored several hypotheses about the role of gap junctions in the nervous system of C. elegans by systematically analysing an anatomical database with recursive algorithms. We find that gap junctions connect different sets of neurons from those connected by chemical synapses. In addition, when analysing the topology of the gap-junction networks, we find that, surprisingly, most (92%) neurons in the worm are linked in a single gap-junction network. The worm nervous system can only be divided into smaller networks by assuming that two or more gap junctions are necessary for functional coupling or that neural activity has limited propagation. However, these groups, and others identified using algorithms with subsets or combinations of restrictive criteria, do not correspond to any known circuits identified in genetic and behavioral studies. Finally, we notice that the function of some gap junctions appears linked to their precise location on the neuronal processes. We propose that the location of the gap junctions within the neuron determines their functional role.

Abstract
We describe in detail a custom-built two-photon microscope based on a modified confocal scanhead (Olympus Fluoview) and mode-locked Ti:sapphire laser (Coherent Mira 900). This system has internal detectors as well as external whole-field detection and an electrooptical modulator for blanking the beam on flyback and effecting fast changes in excitation intensity. This microscope can be used in deep, scattering samples for quantitative measurements with a wide range of fluorophores (GFP, fura, calcium green, calcium orange, fluo-3, DiI, DiO, fluorescein, rhodamine), for fluorescent photobleaching recovery and for uncaging. Images obtained with this system can be deconvolved with the Estimation Maximization algorithm using the program XCOSM (freeware available at: http://www.ibc.wustl.edu/bcl/ xcosm/).

Abstract
Dendritic spines receive most excitatory inputs in the CNS and compartmentalize calcium. Spines also undergo rapid morphological changes, although the function of this motility is still unclear. We have investigated the effect of spine movement on spine calcium dynamics with two-photon photobleaching of enhanced green fluorescent protein and calcium imaging of action potential-elicited transients in spines from layer 2/3 pyramidal neurons in mouse visual cortex slices. The elongation or retraction of the spine neck during spine motility alters the diffusional coupling between spine and dendrite and significantly changes calcium decay kinetics in spines. Our results demonstrate that the spine's ability to compartmentalize calcium is constantly changing.

Abstract
Dendritic spines compartmentalize calcium, and this could be their main function. We review experimental work on spine calcium dynamics. Calcium influx into spines is mediated by calcium channels and by NMDA and AMPA receptors and is followed by fast diffusional equilibration within the spine head. Calcium decay kinetics are controlled by slower diffusion through the spine neck and by spine calcium pumps. Calcium release occurs in spines, although its role is controversial. Finally, the endogenous calcium buffers in spines remain unknown. Thus, spines are calcium compartments because of their morphologies and local influx and extrusion mechanisms. These studies highlight the richness and heterogeneity of pathways that regulate calcium accumulations in spines and the close relationship between the morphology and function of the spine.

Abstract
Dendritic spines receive most excitatory inputs in the CNS and compartmentalize calcium. Although the mechanisms of calcium influx into spines have been explored, it is unknown what determines the calcium decay kinetics in spines. With two-photon microscopy we investigate action potential-induced calcium dynamics in spines from rat CA1 pyramidal neurons in slices. The [Ca(2+)](i) in most spines shows two decay kinetics: an initial fast component, during which [Ca(2+)](i) in spines decays to dendritic levels, followed by a slower decay phase in which the spine follows dendritic kinetics. The correlation between [Ca(2+)](i) in spine and dendrite at the breakpoint of the decay kinetics demonstrates diffusional equilibration between spine and dendrite during the slower component. To explain the faster initial decay, we rule out saturation or kinetic effects of endogenous or exogenous buffers and focus instead on (1) active calcium extrusion and (2) buffered diffusion of calcium from spine to dendrite. The presence of an undershoot in most spines indicates that extrusion mechanisms can be intrinsic to the spine. Supporting the two mechanisms, pharmacological blockade of smooth endoplasmic reticulum calcium (SERCA) pumps and the length of the spine neck affect spine decay kinetics. Using a mathematical model, we find that the contribution of calcium pumps and diffusion varies from spine to spine. We conclude that dendritic spines have calcium pumps and that their density and kinetics, together with the morphology of the spine neck, determine the time during which the spine compartmentalizes calcium.

Abstract
The function of dendritic spines, postsynaptic sites of excitatory input in the mammalian central nervous system (CNS), is still not well understood. Although changes in spine morphology may mediate synaptic plasticity, the extent of basal spine motility and its regulation and function remains controversial. We investigated spine motility in three principal neurons of the mouse CNS: cerebellar Purkinje cells, and cortical and hippocampal pyramidal neurons. Motility was assayed with time-lapse imaging by using two-photon microscopy of green fluorescent protein-labeled neurons in acute and cultured slices. In all three cell types, dendritic protrusions (filopodia and spines) were highly dynamic, exhibiting a diversity of morphological rearrangements over short (<1-min) time courses. The incidence of spine motility declined during postnatal maturation, but dynamic changes were still apparent in many spines in late-postnatal neurons. Although blockade or induction of neuronal activity did not affect spine motility, disruption of actin polymerization did. We hypothesize that this basal motility of dendritic protrusions is intrinsic to the neuron and underlies the heightened plasticity found in developing CNS.

Abstract
The study of neural circuits requires methods for simultaneously recording the activity of populations of neurons. Here, using calcium imaging of neocortical brain slices we take advantage of the ubiquitous distribution of calcium channels in neurons to develop a method to reconstruct the action potentials occurring in a population of neurons. Combining calcium imaging with whole-cell or perforated patch recordings from neurons loaded with acetoxymethyl ester or potassium salt forms of calcium indicators, we demonstrate that each action potential produces a stereotyped calcium transient in the somata of pyramidal neurons. These signals are detectable without averaging, and the signal-to-noise is sufficient to carry out a reconstruction of the spiking pattern of hundreds of neurons, up to relatively high firing frequencies. This technique could in principle be applied systematically to follow the activity of neuronal populations in vitro and in vivo.

Abstract
Dendritic spines receive most excitatory inputs in the vertebrate brain, but their function is still poorly understood. Using two-photon calcium imaging of CA1 pyramidal neurons in rat hippocampal slices, we investigated the mechanisms by which calcium enters into individual spines in the stratum radiatum. We find three different pathways for calcium influx: high-threshold voltage-sensitive calcium channels, NMDA receptors, and an APV-resistant influx consistent with calcium-permeable AMPA or kainate receptors. These pathways vary among different populations of spines and are engaged under different stimulation conditions, with peak calcium concentrations reaching >10 microM. Furthermore, as a result of the biophysical properties of the NMDA receptor, the calcium dynamics of spines are exquisitely sensitive to the temporal coincidence of the input and output of the neuron. Our results confirm that individual spines are chemical compartments that can perform coincidence detection. Finally, we demonstrate that functional studies and optical quantal analysis of single, identified synapses is feasible in mammalian CNS neurons in brain slices.

Abstract
Potentionmetric and spectroscopic (EPR, CD and absorption spectra) data have shown that a fragment of envelope proteins of the hepatitis B virus could be very specific bind molecules for Cu2+ ions using arginine lateral NH2 donor sites. The presence of Pro and Asp residues makes Arg binding not only very specific, but also very efficient.

Abstract
Tumor necrosis factor-alpha is a pluripotent cytokine that is reportedly mitogenic to astrocytes. We examined expression of the astrocyte intermediate filament component glial fibrillary acidic protein in astrocyte cultures and the U373 glioblastoma cell line after treatment with tumor necrosis factor-alpha. Treatment with tumor necrosis factor-alpha for 72 h resulted in a decrease in content of glial fibrillary acidic protein and its encoding mRNA. At the same time, tumor necrosis factor-alpha treatment increased the expression of the cytokine interleukin-6 by astrocytes. The decrease in glial fibrillary acidic protein expression was greater when cells were subconfluent than when they were confluent. Thymidine uptake studies demonstrated that U373 cells proliferated in response to tumor necrosis factor-alpha, but primary neonatal astrocytes did not. However, in both U373 cells and primary astrocytes tumor necrosis factor-alpha induced an increase in total cellular protein content. Treatment of astrocytes and U373 cells for 72 h with the mitogenic cytokine basic fibroblast growth factor also induced a decrease in glial fibrillary acidic protein content and an increase in total protein level, demonstrating that this effect is not specific for tumor necrosis factor-alpha. The decrease in content of glial fibrillary acidic protein detected after tumor necrosis factor-alpha treatment is most likely due to dilution by other proteins that are synthesized rapidly in response to cytokine stimulation.

Abstract
Interleukin-11 (IL-11) is a pleiotropic cytokine with important effects on hematopoietic and other cells. IL-11 was originally described as a product of stromal cell lines and fibroblasts. Using RT-PCR, Northern blotting, and ELISA we demonstrated that the human U373 and U87 glioblastoma cell lines expressed IL-11 and its encoding mRNA when stimulated with IL-1 beta, phorbol ester, and calcium ionophore. The neuroblastoma cell line SH-SY5Y did not express IL-11 mRNA in response to these agents. Cerebral expression of IL-11 by glial cells is important because IL-11 has been shown to have effects on neuronal electrophysiology, has overlapping functions with the neuroactive cytokine interleukin-6, and is part of the gp130-associated neuropoietic family of cytokines.
