Abstract
OBJECTIVE To compare safety and effectiveness of two-different directions of suturing the posterior vaginal breach (horizontal [Ho] vs vertical [Ve]) in women undergoing recto-vaginal endometriosis (RVE) nodule resection. METHODS A multicenter, retrospective, observational, cohort study was performed including all women of reproductive age undergoing RVE nodule resection between March 2013 and December 2018 at our tertiary centers. Patients included in the present study were divided into two groups based on the direction in suturing the posterior vaginal fornix defect, for comparisons in terms of rate of postoperative complications, pain relief, pain and anatomical recurrence, and length of hospital stay. Univariate comparisons were performed adopting the t test or the Mann-Whitney test for continuous data and the chi-square test or the Fisher exact test for categorical data, with a significant P value set to <0.05. RESULTS A total of 101 women were included: 67 in the Ho-group and 34 in the Ve-group. The two groups did not significantly differ in length of hospital stay (6.7 ± 6.9 vs 6.6 ± 3.3 days; P = 0.95), overall postoperative complications (32.8% vs 14.7%; P = 0.05), pain recurrence (35.8% vs 26.5%; P = 0.34) and anatomical recurrence rate (19.4% vs 23.5%; P = 0.62). Conversely, grade III complications were significantly more common in the Ho-group than in the Ve-group (22.7% vs 20%, P = 0.009), while pain relief in terms of deep dyspareunia, dyschezia, dysuria and chronic pelvic pain was more consistent in the Ve-group patients (P = 0.04, 0.04, 0.05, 0.004, respectively). CONCLUSION In symptomatic women undergoing RVE nodule resection, Ho suturing of the vaginal breach appears more commonly associated with severe postoperative complications and a worse pain control.

Abstract
Background:Therapeutic apheresis (TA) represents a therapeutic option in pre-existing conditions or rheumatic diseases that occur during gestation. Although pregnancy is not a contraindication itself, due to the lack of evidence-based guidelines and the alleged risk of maternal and/or fetal adverse events, there is general resistance to its application during pregnancy.Objectives:In this observational study we aimed to evaluate the efficacy and safety of TA in high-risk pregnancies in patients with rheumatic diseases, followed over a decade in a tertiary Center.Methods:Between January 2005 and April 2019, 843 TA procedures were performed during 51 pregnancies in 43 patients: 745 plasma exchange sessions and 98 immunoabsorption sessions. TA was performed in 29 (57%) pregnancies of 21 (48.8%) patients with antiphospholipid antibody syndrome (APS), in 20 (39.2%) pregnancies of 20 (46.5%) patients with congenital heart block (CHB), in 1 (1.9%) pregnancy of 1 (2.3%) patient with systemic sclerosis (SSc) and 1 (1.9%) pregnancy of 1 (2.3%) patient affected by lupic nephritis (SLE).Results:During the period considered, apheresis sessions applied to pregnant women were 7.1% of the total (n = 13.251). The average age at the first treatment was 33 years (range 24-43). The mean management age at the first apheretic treatment was 21 weeks (range 4-32). Twelve (1.4%) apheresis sessions were complicated by adverse events, none required or prolonged hospitalization. There were 44 (86.3%) live births, 3 (5.9%) spontaneous abortions and 2 (3.9%) voluntary terminations of pregnancy, 2 (3.9%) lost to follow-up. The average gestational age at birth was 35 weeks (range 24-37) and cesarean section was performed in 41 (80.4%) cases. TA was added to conventional therapy in 24/29 (82.7%) patients with APS, to the detection of fetal cardiac activity, while in 5/26 (17.3%) it was introduced when the first signs of pregnancy complications such as mild preclampsia, HELLP and IUGR were detected. TA was started within 24 hours of atrioventricular block (AVB) detection; 10/20 (50%) mothers with CHB were diagnosed with 2nd degree AVB, 9/20 (45%) with 3rd degree AVB and one (5%) with sinus bradycardia and endocardial fibroelastosis. The patient with SSc was treated with TA twice a week from the 32nd SG until delivery, which occurred at the 36th SG, due to severe IUGR and oligohydramnios. The patient with SLE complicated by lupic nephritis was treated with TA twice a week, from the 26th SG until the birth, which took place at the 31st SG.Conclusion:Our data have shown that TA in pregnancy is well tolerated. Close collaboration between rheumatologist, obstetrician and specialist in TA is essential to ensure a successful outcome of high-risk pregnancies.Disclosure of Interests: :Anna Colpo: None declared, Piero Marson: None declared, Tiziana Tison: None declared, Alessandra Zambon: None declared, Annalisa La Rosa: None declared, Ermella Zanetti: None declared, Amelia Ruffatti: None declared, Giustina De Silvestro: None declared, Ariela Hoxha Speakers bureau: Celgene, UCB, Novartis, Sanofi, Werfen

Abstract
The origin of dielectric breakdown was studied on 4H-SiC MOSFETs that failed after three months of high temperature reverse bias stress. A local inspection of the failed devices demonstrated the presence of a threading dislocation (TD) at the breakdown location. The nanoscale origin of the dielectric breakdown was highlighted with advanced high-spatial-resolution scanning probe microscopy (SPM) techniques. In particular, SPM revealed the conductive nature of the TD and a local increase of the minority carrier concentration close to the defect. Numerical simulations estimated a hole concentration 13 orders of magnitude larger than in the ideal 4H-SiC crystal. The hole injection in specific regions of the device explained the failure of the gate oxide under stress. In this way, the key role of the TD in the dielectric breakdown of 4H-SiC MOSFET was unambiguously demonstrated.

Abstract
Heat-shock proteins 90 (hsp90s) are a class of molecules able to stabilize a network of 'client' proteins that are involved in several processes. Furthermore, recent studies indicated that mutations in the hsp90-encoding gene induce a wide range of phenotypic abnormalities, which have been interpreted as an increased sensitivity of different developmental pathways to hidden/cryptic mutations. In order to verify the role of hsp90 in aphids, we amplified and sequenced the hsp90 gene in 17 lineages of the peach potato aphid Myzus persicae (Sulzer, 1776) looking for the presence of mutations. In particular, we compared lineages with different reproductive modes (obligate vs. cyclical parthenogenesis), propensity to develop winged females and karyotype stability. Differently from the cyclical parthenogenetic lineages that possessed functional hsp90 genes, the seven analysed asexual lineages showed severe mutations (including frameshift and non-sense mutations). In vivo functional assays with the hsp90-inhibitor geldanamycin showed that some lineages with cyclical parthenogenesis may lose their ability to induce sexuales in the absence of active hsp90 revealing the presence of cryptic mutations in their genomes. As a whole, our data suggest that hsp90 could play in aphids a role in buffering hidden/cryptic mutations that disrupt cyclical parthenogenesis.

Abstract
The aim of this study was to compare the intra and inter genetic variability and population structure of 7 indigenous chicken breeds of the Veneto region, through a novel panel of 64 SNP, each located in an exonic region and mostly on different chromosomes. A total of 753 blood samples from 7 local chicken breeds (Ermellinata di Rovigo, Millefiori di Lonigo, Polverara, Pepòi, Robusta Lionata, Robusta Maculata, and Padovana) was collected and analyzed. Two strains of Polverara (Nera and Bianca) and Padovana (Dorata and Camosciata) were included in the study. The observed heterozygosity ranged from 0.124 (Pèpoi) to 0.244 (Ermellinata di Rovigo), and the expected heterozygosity varied from 0.132 (Millefiori di Lonigo) to 0.300 (Ermellinata di Rovigo). Global FIS results (0.114) indicated a low-medium inbreeding effect, with values ranging from 0.008 (Millefiori di Lonigo) to 0.223 (Ermellinata di Rovigo). Pairwise FST values (0.167) for all populations ranged from 0.020 (Polverara Nera and Polverara Bianca) to 0.193 (Robusta Lionata and Polverara Nera), indicating that the studied breeds were genetically highly differentiated. The software STRUCTURE was used to detect the presence of population substructures, and the most probable number of clusters (K) of the 10 chicken populations was at K = 8. The affiliation was successful in all Veneto chicken breeds. The present SNP marker results, compared with previous data obtained using microsatellites, provided a reliable estimate of genetic diversity within and between the studied breeds, and demonstrated the utility of the proposed panel as a rapid, efficient, and cost-effective tool for periodical monitoring of the genetic variability among poultry populations. In addition, the present SNP panel could represent a resource for a systematic approach with relevant impact on breeding program decisions and could turn out to be a reliable tool for genetic traceability of indigenous chicken meat. Adoption of a periodical monitoring system of genetic diversity is a fundamental tool in conservation actions and should increase the value of typical and niche products.

Abstract
The first case of severe drug-induced gastrointestinal injury related to levodopa is described. The 86-year-old patient experienced acute colitis temporally related to the intake of the drug with complete resolution of symptoms on levodopa withdrawal. Awareness of the possibility of a levodopa-related damage on colon biopsies performed for acute colitis is of paramount importance for pathologists. However, in order to exclude or confirm a drug-related damage an effective communications between clinicians and pathologists is always required.

Abstract
About 100 km east of Rome, in the central Apennine Mountains, a critically endangered population of ∼50 brown bears live in complete isolation. Mating outside this population is prevented by several 100 km of bear-free territories. We exploited this natural experiment to better understand the gene and genomic consequences of surviving at extremely small population size. We found that brown bear populations in Europe lost connectivity since Neolithic times, when farming communities expanded and forest burning was used for land clearance. In central Italy, this resulted in a 40-fold population decline. The overall genomic impact of this decline included the complete loss of variation in the mitochondrial genome and along long stretches of the nuclear genome. Several private and deleterious amino acid changes were fixed by random drift; predicted effects include energy deficit, muscle weakness, anomalies in cranial and skeletal development, and reduced aggressiveness. Despite this extreme loss of diversity, Apennine bear genomes show nonrandom peaks of high variation, possibly maintained by balancing selection, at genomic regions significantly enriched for genes associated with immune and olfactory systems. Challenging the paradigm of increased extinction risk in small populations, we suggest that random fixation of deleterious alleles (i) can be an important driver of divergence in isolation, (ii) can be tolerated when balancing selection prevents random loss of variation at important genes, and (iii) is followed by or results directly in favorable behavioral changes.

Abstract
Aims of the research were to devise a proteome map of the chicken Pectoralis superficialis muscle, as resolved by two-dimensional gel electrophoresis, and to characterize protein expression changes in the soluble protein fraction in commercial conditions due to age and to time in transit before slaughtering. Broilers were reared under commercial conditions until they reached a mean 1.8 kg and 36 d, or 2.6 kg and 46 d of age. Transport to the slaughterhouse took 90 or 220 minutes. Transport-induced stress was assessed from blood metabolites and leukocyte cell counts, revealing significant changes in albumin, glucose and triglyceride concentrations, in heterophils and leukocyte counts for chickens in transit for longer, and in glucose depending mainly on age. The sarcoplasmic protein fractions were extracted from a total of 39 breast muscle samples, collected 15 min post mortem, for analysis by two-dimensional electrophoresis. Image and statistical analyses enabled us to study the qualitative and quantitative differences between the samples. Twelve up- or down-regulated protein spots were detected (P < 0.05): 8 related to the age effect, 2 to time in transit, and 2 to the interaction between the two. Age and time in transit influenced the avian proteome regulating the biological processes linked to the cellular housekeeping functions, related mainly to metabolism, cell division and control of apoptosis. Principal component analysis clustering was used to assess differences between birds. Age difference discriminated between the chickens analyzed better than time in transit, which seemed to have less general impact on the proteome fraction considered here. Isolating and identifying the proteins whose expression changes in response to transport duration and age shed some light on the biological mechanisms underlying growth and stress-related metabolism in chickens. Our results, combined with a further characterization of the chicken proteome associated with commercial chicken slaughtering management, will hopefully inspire alternative strategies and policies, and action to reduce the impact of stress related to time in transit.

Abstract
AIM To assess the major determinants of glucose tolerance between age, genotype, and clinical status in cystic fibrosis (CF) patients, and study if defects of insulin secretion and insulin sensitivity were associated with the onset of CF-related diabetes (CFRD). SUBJECTS AND METHODS One hundred and nineteen patients, in stable clinical condition were studied. They were subdivided into 3 groups based on age, and 2 groups based on Schwachman-Kulczycki clinical score. All patients were genotyped, and subsequently divided into 3 groups. Ninety-four healthy normal-weight controls, comparable for sex and age were also studied. All subjects had baseline blood samples taken for glucose and insulin, C-peptide, and glycated hemoglobin. Homeostasis model assessment of insulin resistance (HOMA-IR), fasting glucose/insulin ratio (FGIR) were calculated as indices of IR and insulinogenic index as a marker of pancreatic β-cell function. All patients underwent an oral glucose tolerance test, and 57 underwent an IVGTT for the calculation of first-phase (FPIR) and acute insulin responses (AIR). RESULTS The F508del homozygous patients had an increased chance of developing impaired glucose tolerance (IGT) and significantly lower FPIR, decreased HOMA-IR, and insulinogenic index. Heterozygote F508del patients had an increased chance of having normal glucose tolerance. HOMA-IR, FGIR, and insulinogenic index did not change with age or clinical score. HOMAIR correlated with FPIR. FPIR correlated positively with insulinogenic index. AIR correlated negatively with FGIR, and positively with C-reactive protein. In multiple linear regression analyses, glucose tolerance was related to the agegroup, and to the HOMA-IR and insulinogenic indexes. CONCLUSIONS IGT and CFRD were related mainly to genotype, although, as expected, the prevalence increased with age. The data suggested a possible combined contribution of insulin deficiency, β-cell function, and reduced insulin sensitivity to the onset of CFRD; however, further studies are warranted to better elucidate this aspect.

Abstract
BACKGROUND Ischemic episodes lead to profound functional and structural alterations of the gastrointestinal tract which may contribute to disorders of intestinal motility. Enhancement of glutamate overflow and the consequent activation of NMDA (N-methyl-D-aspartate) receptors may participate to such changes by modulating different enteric neurotransmitter systems, including cholinergic motor pathways. METHODS The molecular mechanism/s underlying activation of NMDA receptors in the guinea pig ileum were investigated after glucose/oxygen deprivation (in vitro ischemia) and during reperfusion. KEY RESULTS The number of ileal myenteric neurons positive for NR1, the functional subunit of NMDA receptors, and its mRNA levels were unchanged after in vitro ischemia/reperfusion. In these conditions, the protein levels of NR1, and of its phosphorylated form by protein kinase C (PKC), significantly increased in myenteric neurons, whereas, the levels of NR1 phosphorylated by protein kinase A (PKA) did not change, with respect to control values. Spontaneous glutamate overflow increased during in vitro ischemia/reperfusion. In these conditions, the NMDA receptor antagonists, D(-)-2-amino-5-phosphonopentanoic acid [(D)-AP5] (10 μmol L(-1)) and 5,7-dichlorokynurenic acid (5,7-diClKyn acid) (10 μmol L(-1)) and the PKC antagonist, chelerythrine (1 μmol L(-1)), but not the PKA antagonist, H-89 (1 μmol L(-1)), were able to significantly depress the increased glutamate efflux. CONCLUSIONS & INFERENCES The present data suggest that in the guinea pig ileum during in vitro ischemia/reperfusion, NR1 protein levels increase. Such event may rely upon posttranscriptional events involving NR1 phosphorylation by PKC. Increased NR1 levels may, at least in part, explain the ability of NMDA receptors to modulate a positive feedback on ischemia/reperfusion-induced glutamate overflow.

Abstract
The objectives of this study were to determine genetic variation and to analyze population structure of 6 Italian local chicken breeds involved in a conservation program. Twenty microsatellite markers were investigated in 337 birds belonging to 6 breeds: Ermellinata di Rovigo, Robusta Maculata, Robusta Lionata, Pépoi, Padovana, and Polverara; a commercial layer cross was used as reference. One hundred twelve alleles were detected in the overall population, with a mean number of 5.6 +/- 2.1 alleles per locus. For the local breeds, the observed and expected heterozygosity ranged from a minimum of 0.240 to a maximum of 0.413 and from 0.243 to 0.463 for the Pépoi and Polverara breeds, respectively. Deviation from Hardy-Weinberg equilibrium was observed in 5 breeds and in the commercial cross. The overall population heterozygote deficiency was 0.427, the average inbreeding coefficient was 0.097, and the heterozygote deficiency due to breed subdivisions was 0.437. Reynolds' distances were used to draw an unrooted neighbor-joining tree, which topology gave information on the genetic origin of these breeds and confirmed their known history. The estimated molecular kinship within a breed ranged from 0.559 to 0.769, evidencing high coancestry. Structure analysis was performed to detect the presence of population substructures. Inferred clusters corresponded to the different breeds, without presence of admixture. The exception was the Polverara breed, for which a more complex genetic structure was found. The results supported the decision of safeguarding these breeds as an important reservoir of genetic diversity and confirmed the usefulness of microsatellite markers to characterize and to monitor genetic variability in local chicken breeds.

Abstract
The genetic variability and presence of population substructures in 4 native Northern Italian sheep breeds, Alpagota, Brogna, Foza, and Lamon, undergoing in situ conservation, and 1 widespread Italian breed, Bergamasca, were studied by investigating 19 microsatellite markers. The breeds showed considerable genetic variability in terms of number of alleles and heterozygosity, with the exception of Alpagota, which was the least variable (0.607). Nevertheless, a significant deficit of heterozygotes was observed in each breed due to rather increased levels of inbreeding or to the presence of population substructures, probably caused by increased genetic variation in the founder populations. The analyses evidenced clear genetic differentiation (F(ST) = 0.085), reduced levels of admixture, and presence of private alleles among the breeds, confirming their genetic uniqueness. In particular, according to Reynolds genetic distances, Alpagota was the most differentiated, perhaps because it had been bred mostly in a rather isolated area. Loss of any of the investigated breeds would result in a loss of genetic diversity ranging from 0.5 to 1.6% of the total observed gene diversity. Results supported the decision to safeguard these breeds as important reservoirs of genetic diversity and suggested breeding and mating practices to maintain variability and to overcome within-breed substructures.

Abstract
In the guinea pig colon, chronic sympathetic denervation entails supersensitivity to inhibitory mu-opioid agents modulating cholinergic neurons. The mechanism underlying such adaptive change has not yet been unravelled, although protein kinase C (PKC) may be involved. A previous study indirectly demonstrated that activation of mu-opioid receptors on myenteric neurons facilitates PKC activity. Such coupling may counteract the inhibitory action of mu-opioid agents on acetylcholine overflow, since PKC, per se, increases this parameter. After chronic sympathetic denervation such restraint abates, representing a possible mechanism for development of supersensitivity to mu-opioid agents. In the present study, this hypothesis was further investigated. After chronic sympathetic denervation, Ca(2+)-dependent PKC activity was reduced in colonic myenteric plexus synaptosomes. The mu-opioid agent, DAMGO, increased Ca(2+)-dependent PKC activity in synaptosomes obtained from normal, but not from denervated animals. In myenteric synaptosomes obtained from this experimental group, protein levels of Ca(2+)-dependent PKC isoforms betaI, betaII and gamma decreased, whereas alpha levels increased. In whole-mount preparations, the four Ca(2+)-dependent PKC isoforms co-localized with mu-opioid receptors on subpopulations of colonic myenteric neurons. The percentage of neurons staining for PKCbetaII, as well as the number of mu-opioid receptor-positive neurons staining for PKCbetaII, decreased in denervated preparations. The same parameters related to PKCalpha, betaI or gamma remained unchanged. Overall, the present data strengthen the concept that mu-opioid receptors located on myenteric neurons are coupled to Ca(2+)-dependent PKCs. After chronic sympathetic denervation, a reduced efficiency of this coupling may predominantly involve PKCbetaII, although also PKCbetaI and gamma, but not PKCalpha, may be implicated.

Abstract
Healthcare workers are a category of subjects at risk of infections higher than general population, though the introduction of vaccination against hepatitis B generally reduced this risk. In the present research, 2137 students of graduate course for health professions were subdivide in two age classes: 25 years old or younger and older than 25 years old according to the vaccination strategy defined by the law 165/91. A high number of students (82.3%) appeared immune against hepatitis B virus, whereas 16.7% were negative. About 30% of negative subjects declared vaccination. Females and subjects 25 years old or younger showed a significantly higher prevalence of anti-HBsAg antibodies (p < 0.001) than males and older subjects respectively. The obtained results show the need to evaluate the immunity status of the healthcare workers in training with the aim to reduce the number of susceptible subjects.

Abstract
Antibodies against viral hepatitis A, B and C were evaluated in 221 students of graduate courses of the Medical School of Padua University born in countries different from Italy. Data were compared with those measured in 362 students born in Veneto Region and 87 students born in Centre-Southern Italy. The results showed a high, significant prevalence of positive antibodies against hepatitis A in students from Africa (94.7%), Asia (60.9%), Centre-Southern America (60.9%) and East Europe (52.7%); in Italy, the prevalence was significant in student from Centre-Southern Italy (19.5%). A high prevalence of hepatitis B antibodies was observed in 33.3% of Africa students (two subjects HBsAg positive), in 22.6% of students from East Europe (five subjects HBsAg positive) and in 12.5% of Asian and Centre-Southern American students (one HBeAg positive). Finally, infection with hepatitis C is sporadic and without a significant geographic distribution (three subjects only).

Abstract
PURPOSE To evaluate whether the organ culture method for human cornea preservation may be applied to corneas stored for several days at 4 degrees C. METHODS The cell density, viability, and morphology of corneal endothelium were examined in 140 human corneas stored at 4 degrees C for the minimal time required for transport to the bank and for the preliminary controls of cornea status (1.6 +/- 1.1 days) and in 46 corneas preserved at 4 degrees C for 6.1 +/- 1.9 days in Optisol-GS. The evaluation was repeated after 19.7 +/- 9.1 days of incubation at 31 degrees C in a culture medium containing 2% newborn calf serum. RESULTS After the hypothermic storage the corneal endothelium had a mean density of 2475 +/- 159 cells/mm2 without significant difference between the short and the long-term incubation. Several corneas of the two groups showed signs of endothelium degeneration and were positive to trypan blue test. After the incubation at 31 degrees C, the corneas with endothelial degeneration decreased by 52.2% and those positive to trypan blue decreased by 21.7%. Polymorphism (enlarged endothelial cells) increased from 9.6% to 14.5% of the corneas. The remodeling of the endothelium led to a 6.7% decrease in cell density. These results were similar after short-term and long-term storage at 4 degrees C. CONCLUSIONS Organ culture was effective in improving corneal endothelium when the hypothermic storage was prolonged to the upper temporal limit for this procedure (7-10 days). These results may encourage the possibility of an eye bank to allocate the available cornea pool, thus decreasing the risk of discarding precious material.

Abstract
PURPOSE To evaluate whether the organ culture method for human cornea preservation may be applied to corneas stored for several days at 4 degrees C. METHODS The cell density, viability, and morphology of corneal endothelium were examined in 140 human corneas stored at 4 degrees C for the minimal time required for transport to the bank and for the preliminary controls of cornea status (1.6 +/- 1.1 days) and in 46 corneas preserved at 4 degrees C for 6.1 +/- 1.9 days in Optisol-GS. The evaluation was repeated after 19.7 +/- 9.1 days of incubation at 31 degrees C in a culture medium containing 2% newborn calf serum. RESULTS After the hypothermic storage the corneal endothelium had a mean density of 2475 +/- 159 cells/mm2 without significant difference between the short and the long-term incubation. Several corneas of the two groups showed signs of endothelium degeneration and were positive to trypan blue test. After the incubation at 31 degrees C, the corneas with endothelial degeneration decreased by 52.2% and those positive to trypan blue decreased by 21.7%. Polymorphism (enlarged endothelial cells) increased from 9.6% to 14.5% of the corneas. The remodeling of the endothelium led to a 6.7% decrease in cell density. These results were similar after short-term and long-term storage at 4 degrees C. CONCLUSIONS Organ culture was effective in improving corneal endothelium when the hypothermic storage was prolonged to the upper temporal limit for this procedure (7-10 days). These results may encourage the possibility of an eye bank to allocate the available cornea pool, thus decreasing the risk of discarding precious material.

Abstract
Lipid-based vectors are a promising tool for gene therapy applications. Several studies have reported their use in vivo to transfect different organs. Few data, however, are available about lipid-mediated gene transfer in skeletal muscle. Here we report the initial results obtained after systemic administration of lipopolyplexes based on the DODAC cationic lipid in an animal model of muscle regeneration. In particular, we compared three routes of administration: intravenous (i.v.), intracardiac (IC) and intra-arterial (IA). Analysis of reporter gene expression (luciferase) showed that regenerating muscle is more efficiently transfected in all cases and that IA injection is by far the best approach.

Abstract
To assess the role of AMPA and kainate receptors in modulating neurotransmitter release from the myenteric plexus, the effect of alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) and kainic acid on endogenous acetylcholine (ACh) and noradrenaline (NA) overflow from the guinea-pig isolated colon was studied. AMPA inhibited spontaneous ACh overflow and increased electrically-evoked NA overflow. Kainic acid did not influence both ACh and NA overflow. AMPA-mediated effects on ACh and NA overflow were significantly reduced by the AMPA/kainate antagonist, 6-cyano-7-nitroquinoxaline-2,3-dione, CNQX. The inhibitory effect of AMPA on ACh overflow could be due, at least in part, to the AMPA-induced NA overflow as it was greatly reduced after adrenoceptor blockade and virtually abolished in sympathetically-denervated animals. The possible functional significance of these findings was studied by measuring the efficiency of the peristaltic reflex in the presence of the different agonists. The efficiency of peristalsis was enhanced by AMPA, whereas it was not modified by kainic acid. In conclusion, AMPA receptors, but not kainate receptors, may play a role in the modulation of ACh and NA release and of peristalsis in the guinea-pig colon.

Abstract
Antithrombin III (AT III) deficiency is associated with a high risk of venous thromboembolism, particularly in pregnancy. As prophylactic treatment it has been recommended that plasma levels of AT III be normalized by use of AT III concentrates, in addition to heparin. - We report on the prophylactic treatment of three sisters (age 21, 25, and 32 years) with congenital AT III deficiency (38-53%, normal 80-120%) and reduced inducible fibrinolytic activity (1.2, 5.8, 1.2%, normal greater than 8.5%), who had already had severe thromboembolism. During pregnancy prophylactic measures were taken individually, depending on the plasma level of beta thromboglobulin (BTG) determined every 2-3 weeks. In two patients prophylaxis with s.c. heparin (2 X 7500 IU/d) was started at the time of the first increase of BTG (around 10th week of gestation), leading to normalization of BTG. When BTG was again elevated, the dose of heparin was increased stepwise to 2 x 15,000 IU/d; in this way functional AT III levels remained in the range of 28-50%. Thus, these two patients received only heparin throughout pregnancy. However, in the third patient BTG levels could not be normalized by heparin alone (60-130 ng/ml, normal less than 43 ng/ml). Injections of AT III concentrate (1000 IU) led to reduction of BTG within 2 hours (60----42,220----61 ng/ml). Therefore, AT III was given from the 25th week of gestation in increasing amounts up to 5000 IU/week (funct. AT III in plasma 51-72%) in addition to heparin (2 x 12,500 IU/d), resulting in BTG levels of 33-51 ng/ml.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A series of 13470 hysterosalpingographic investigations demonstrated congenital uterine malformations in 1160 cases (8.6%). Uterus arcuatus and uterine hypoplasia, the latter ranking as a malformation on embryological grounds, together accounted for two-thirds of the cases, uterus unicornis unicollis and uterus bicornis unicollis together for over a quarter and the others, uterine didelphys, uterus bicornis bicollis and uterus septus/subseptus, for much smaller percentages. Each malformation is described and illustrated by typical hysterosalpingograms. In addition to its decisive importance in diagnosis, hysterosalpingography it also valuable in planning surgical correction in many cases.
