Abstract
Cardiopulmonary exercise testing (CPET) is an important tool in assessing the functional status of patients with pulmonary arterial hypertension (PAH). During CPET, continuous electrocardiography (ECG) is used as a marker of exercise-induced ischemia or arrhythmia. We hypothesize that ECG changes with exercise may be an early indicator of clinical worsening in PAH and could predict adverse outcomes. Clinical, hemodynamic, and CPET data of 155 children and young adult patients with PAH who underwent CPET between 2012 and 2019 in our pulmonary hypertension (PH) center were included in this retrospective analysis. ECGs were analyzed for ST depressions and T-wave inversions, along with coincident hemodynamic data. These data were correlated with adverse outcomes divided into 2 categories: severe worsening (death or receiving lung transplant) and mild to moderate worsening (PAH medication escalation, hospitalization, shunt creation, or listing for lung transplant). The median age was 19 years (range 7 to 40 years), 69% were female, and the average follow-up time was 5 years (range 1 to 8 years). A total of 63 patients (41%) had at least 1 adverse outcome. A total of 39 patients (25%) demonstrated significant ST-T-wave changes with exercise. Patients with ST-T-wave changes were 20% more likely to die or need lung transplant than those without. The multiple linear regression found that ST-T-wave changes were a predictor of elevated mean pulmonary arterial pressure (mPAP) found on catheterization (R = 0.489, p = 0.003), although not of pulmonary vascular resistance index (R = -0.112, p = 0.484). An mPAP of 55 mm Hg was the most sensitive and specific point in identifying when ST-T-wave changes with exercise begin to appear. In conclusion, ST-T-wave changes on exercise ECG are significantly associated with adverse outcomes in PH in a medium-term follow-up study, and the presence of ST-T-wave changes correlates with higher mPAP. These ECG changes with exercise may be used as early indicators of clinical worsening in PH and predictors of adverse outcomes.

Abstract
BACKGROUND The present study investigates whether epigenetic differences emerge in the heart of patients undergoing cardiac surgery for an aortic valvular replacement (AVR) or coronary artery bypass graft (CABG). An algorithm is also established to determine how the pathophysiological condition might influence the human biological cardiac age. RESULTS Blood samples and cardiac auricles were collected from patients who underwent cardiac procedures: 94 AVR and 289 CABG. The CpGs from three independent blood-derived biological clocks were selected to design a new blood- and the first cardiac-specific clocks. Specifically, 31 CpGs from six age-related genes, ELOVL2, EDARADD, ITGA2B, ASPA, PDE4C, and FHL2, were used to construct the tissue-tailored clocks. The best-fitting variables were combined to define new cardiac- and blood-tailored clocks validated through neural network analysis and elastic regression. In addition, telomere length (TL) was measured by qPCR. These new methods revealed a similarity between chronological and biological age in the blood and heart; the average TL was significantly higher in the heart than in the blood. In addition, the cardiac clock discriminated well between AVR and CABG and was sensitive to cardiovascular risk factors such as obesity and smoking. Moreover, the cardiac-specific clock identified an AVR patient's subgroup whose accelerated bioage correlated with the altered ventricular parameters, including left ventricular diastolic and systolic volume. CONCLUSION This study reports on applying a method to evaluate the cardiac biological age revealing epigenetic features that separate subgroups of AVR and CABG.

Abstract
We present a case of a newborn with a rare presentation of obstructed supracardiac total anomalous pulmonary venous connection who required emergent cannulation to extracorporeal membrane oxygenation (ECMO). Computed tomographic angiography of the heart was performed and using novel virtual dissection techniques aided in surgical planning and guidance. Computed tomographic angiography can be successfully performed in neonates with complex congenital heart disease on ECMO without adjustment of flows to aid in surgical management and novel virtual dissection techniques aid in complex anatomical delineation and spatial orientation with noncardiac structures. The preoperative imaging in this case allowed for appropriate and detailed presurgical planning and contributed to the excellent outcome of this patient.

Abstract
Ozone (O3) is one of the most harmful urban pollutants, but its biological mechanisms have not been fully elucidated yet. Human bronchial epithelial cells (HBEpC) and human macrophage cells (differentiated human monocytic cell line) were exposed to O3 at the concentration of 240 μg/m3 (120 ppb), corresponding to the European Union alert threshold. Cell viability, reactive oxygen species (ROS) production, and pro-inflammatory cytokines release (IL-8 and TNF-α) were evaluated. Results indicated that O3 exposure increases ROS production in both cell types and enhances cytokines release in macrophages. O3 stimulated IL-8 and TNF-α in HBEpC when the cells were pretreated with Lipopolysaccharide, used to mimic a pre-existing inflammatory condition. Proteomics analysis revealed that, in HBEpC, O3 caused the up-regulation of aldo-keto reductase family 1 member B10, a recognized critical protein in lung carcinogenesis. In conclusion, our results show that 120 ppb O3 can lead to potential damage to human health suggesting the need for a revision of the actual alert levels.

Abstract
PURPOSE OF REVIEW COVID-19-related guidance has changed dramatically since the onset of the pandemic. Awareness of data regarding prevention of disease, the cardiac manifestations and treatment of acute COVID-19 and multisystem inflammatory syndrome in children, and return to physical activity following an infection allows for appropriate adjustment of current care models and guides future study. RECENT FINDINGS Severe acute respiratory syndrome coronavirus 2 transmission can be reduced using various mitigation strategies, though their effectiveness differs based on viral prevalence. The risk of severe disease during acute COVID-19 infection is low in children and adolescents, though specific risk factors have been identified. COVID-19 vaccination significantly decreases the risk of severe disease and poor outcomes. Regular physical activity positively affects well being and has been a focus of recent guidance regarding well tolerated return to activities following an infection. SUMMARY The use of strategies to reduce viral transmission will depend on individuals' and communities' risk tolerance and on current viral prevalence. COVID-19 vaccination should be encouraged, particularly in patients with identified risk factors. Allowing children and adolescents to safely participate in physical and other activities should continue to be a focus of our clinical and research efforts given their myriad benefits in this population.

Abstract
Cigarette smoke exposure represents a well-established ovotoxic exogenous stress, but the molecular mechanisms underlying of this effect are still unclear. Cigarette smoke upregulates inflammatory genes in the female reproductive organs, therefore an abnormal inflammation response may contribute to the impairment of female fertility. In this study we investigated for the first time the effect of cigarette smoke exposure on NOS and COX expression and activity and on their transcription factors (CREB and NF-kB) in human GCs and on the release of NO and PGE2 in the FF in smoking and non-smoking patients undergoing IVF treatment. In addition, correlation analysis between AMH serum levels, an index of ovarian reserve, and smoking exposure or iNOS and COX-2 protein expression levels were performed using a Pearson correlation method. Cigarette smoke exposure resulted in a significant increase of iNOS and COX-2 protein expression together with an increase of iNOS activity and PGE2 levels. pNF-kB and pCREB protein expression were upregulated in the GCs of smokers compared to non-smokers. The habit of smoking was negatively correlated with serum AMH levels, and positively correlated with iNOS and COX-2 protein expression levels. The data presented in the current study revealed a novel molecular mechanism underlying the toxic effects of cigarette smoke on fertility. Additional pathways mediating the effects of cigarette smoke exposure in human GCs cannot be excluded and should be investigated in future studies.

Abstract
Background The ratio of early diastolic mitral inflow velocity (E) to early diastolic mitral annular tissue velocity (e’), or E/e’, is an echocardiographic measure of left ventricular filling pressure. Peri‐operative changes in E/e’ and association with outcomes have been demonstrated in adults undergoing surgery for aortic stenosis (AS). We sought to explore changes in E/e’ and other diastolic indices in the setting of congenital AS surgery and to assess for association with post‐operative outcomes among children and young adults. Methods A retrospective, single‐center study was performed among patients 6 months to 30 years of age who underwent congenital AS surgery from 2006 to 2018. Tissue Doppler indices were collected from pre‐ and post‐operative echocardiograms. Post‐operative outcomes were reviewed. Results Sixty‐six subjects with subvalvar (45%), valvar (47%), and supravalvar (8%) AS underwent surgery at a median age of 9.5 years (IQR: 4.0–14.8). Pre‐operatively, the lateral E/e’ ratio was 8.6 (6.7–11.0); 33% had E/e’≥10. Post‐operatively, the lateral e’ decreased to 9.9 cm/s (8.0–11.4), the E/e’ ratio increased to 10.4 (8.3–13.1); and 53% had E/e’≥10 (p‐values < 0.0001, 0.0072, and < 0.001, respectively). Pre‐operative lateral e’ correlated modestly with duration of intubation (ρ = −0.24, p‐value 0.048) and post‐operative lateral e’ correlated modestly with duration of intubation and length of hospital stay (ρ = −0.28 and −0.26, p‐values = 0.02 and 0.04, respectively). Conclusions Children and young adults who underwent congenital AS surgery had echocardiographic evidence of diastolic dysfunction pre‐operatively that worsened post‐operatively. Lateral e’ may be a sensitive indicator of impaired ventricular relaxation in these patients and may impact duration of intubation and hospital stay.

Abstract
Healthcare workers (HCWs) can be considered at an increased risk of developing occupational contact dermatitis (OCD) due to repetitive hand washing with soaps and disinfectants and extended use of gloves for many hours during the day. The aim of this study was to summarize the incidence of OCD in HCWs. We searched the databases PubMed/MEDLINE (1980-present), EMBASE (1980-present) and Cochrane Library (1992-present) through May 2020 using the search term 'incidence of contact dermatitis in HCWs' according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Overall, 16 studies (six cohorts; 10 register-based) with follow-up periods between 1987 and 2013 fulfilled the inclusion criteria. The incidence of OCD reported in studies using registers of occupational diseases ranged from 0.6 to 6.7 per 10 000 person-years. The cohort studies reported incidence from 15.9 to 780.0 per 10 000 person-years; the incidence was higher in studies which included apprentice nurses. A higher incidence was also observed amongst dental practitioners, particularly dental technicians and nurses, compared to other HCWs. Studies reporting incidence data are very scarce and results differed by study design, type of contact dermatitis and investigated HCWs. Our study highlighted the dearth of high-quality data on the incidence of OCD and the possible underestimation of disease burden. Prospective cohort studies with harmonized designs, especially exposure assessment and outcome ascertainment, are required to provide more accurate, valid and recent estimates of the incidence of OCD. A high incidence amongst specific occupational groups suggests the need to undertake intervention studies with a focus on prevention, particularly during pandemics such as COVID-19.

Abstract
Abstract
Background
Reactive oxygen species (ROS) and oxidative stress in the respiratory system are involved in lung inflammation and tumorigenesis. Ozone (O3) is one of the main components of air pollution in urban areas able to act as strong pro-oxidant agent, however its effects on human health is still poorly investigated. In this study the effect of O3 has been evaluated in THP-1 monocytes differentiated into macrophages with PMA and in HBEpC (primary human bronchial epithelial) cells, two model systems for in vitro studies and translational research.
Methods
Cell viability, ROS and pro-inflammatory cytokines like interleukin-8(IL-8) and tumor necrosis factor(TNF-α) have been tested in the above-mentioned cell lines not exposed to any kind of pollution (basal condition-b.c.) or exposed to O3 at a concentration of 120 ppb. In HBEpC a labelfree shotgun proteomics analysis has been also performed in the same conditions.
Results
Ozone significantly increased the production of IL-8 and TNF-α in THP-1 whereas no changes were shown in HBEpC. In both cell lines lipopolysaccharide(LPS) caused an increase of IL-8 and TNF-α production in b.c. and O3 treatment potentiated this effect. Ozone exposure increased ROS formation in a time dependent manner in both cell lines and in THP-1 cells a decrease in catalase activity was also shown. Finally, according to these data, functional proteomics analysis revealed that in HBEpC exposure to O3 many differential proteins are related to oxidative stress and inflammation.
Conclusions
Our results indicate that O3, at levels that can be reached in urban areas, causes an increase of pro-inflammatory agents either per se or potentiating the effect of immune response stimulators in cell models of human macrophages and human airway epithelial cells. Interestingly, the proteomic analysis showed that besides the dysregulated proteins, O3 induced the expression of AKR1D1 and AKR1B10, proteins recognized to play a significant role in cancer development.
Key messages
This study adds new pieces of information on the association between O3 exposure and detrimental effects on respiratory system. This study suggests the need for further research on the mechanisms involved and for a continued monitoring/re-evaluation of air pollution standards aimed at safeguarding human health.

Abstract
Minimally invasive Heller myotomy is considered the gold standard surgical approach for symptomatic achalasia because it is a safe and effective procedure. Over the last years, several studies comparing the laparoscopic and robotic approach for Heller myotomy have been published. Although the robotic approach appears to have some advantages over standard laparoscopy, data on this topic are still controversial and no definite conclusions have been drawn. This metanalysis has been designed to systematically evaluate and compare the effectiveness and safety of the robot-assisted Heller myotomy as compared to the standard laparoscopic approach. According to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines, a systematic search on both laparoscopic and robotic Heller myotomy was performed in all the major electronic databases (PubMed, Web of Science, Scopus, EMBASE), using the following search string: (achalasia OR Dor) AND robotic. Six articles were included in the final analysis. A metaregression analysis was performed to assess the possible effects of demographic variables (age, gender, body mass indes (BMI)) and previous abdominal surgery or endoscopic intervention on the analyzed outcomes. No statistical difference was observed in operative times (mean difference (MD) = 20.79, P = 0.19, 95% confidence interval (CI) -10.05,51,62), estimated blood loss (MD = -17.10, P = 0.13, 95% CI -40.48,5.08), conversion rate to open surgery (risk difference (RD) = -0.01, P = 0.33, 95% CI -0.05,0.02), length of hospital stay (MD = -0.73, P = 0.15, 95% CI -1.71,0.25) and long-term recurrence (odds ratio (OR) = 0.59, P = 0.45, 95% CI 0.15,2.33). On the contrary, the robotic approach was found to be associated with a significantly significant lower rate of intraoperative esophageal perforations (OR = 0.13, P < 0.001, 95% CI 0.04, 0.45). Our results suggest that the robotic approach is safer than the laparoscopic Heller myotomy, encouraging the use of robot-assisted surgery. However, our analysis is limited because of the exiguous number of comparative studies and because most of the included studies were statistically underpowered, given the small sample size. Moreover, a high degree of heterogeneity was observed in most of published studies. Taking in consideration the additional costs of robot-assisted procedures, larger Randomized Controlled Trials (RCTs) are advocated to confirm the safety and effectiveness of the robotic approach, and its advantages over standard laparoscopic surgery. In conclusion, well-designed prospective trials and RCTs with homogeneous parameters are needed to draw definitive conclusions about the best surgical approach to pursue in treating symptomatic achalasia.

Abstract
Abstract
Background
Cardiac stromal cells are the most abundant cell type present in the heart, where they have an important homeostatic function in matrix renewal and electromechanical coupling. We have shown that YAP transcription factor (a component of the Hippo pathway) is important for the proliferation of these cells and, potentially, pathologic cardiac matrix stiffening in heart failure.
Purpose
Given the role of Hippo pathway in cell mechanosensation, we assessed the conditions for activation of the YAP-dependent transcriptional pathway related to geometry/strain sensing using human “cardiosphere”-derived cells.
Methods
Human cardiospheres (C-Sp) and C-Sp-derived cells (CDCs) were obtained from fragments of atrial appendages of patients admitted for AoC bypass. C-Sps and CDCs were cultured using published methods. To analyze cell/nuclear geometry in 2D/3D culture, we employed an adapting thresholding algorithm allowing segmentation of cell membrane/nuclei shape and the relative abundance of nuclear/cytoplasmic fluorescence intensities from z-stacked confocal immunofluorescence images. Inhibitors of signaling cascades converging onto actin cytoskeleton polymerization or of YAP/TEADs interaction were used to assess YAP target genes transcription.
Results
Previous results showed stiffness sensitivity of YAP nuclear translocation process. Namely, CDCs plated onto stiff (E >50kPa) culture plates exhibited high ratios of nuclear/cytoplasmic YAP, as compared to cells plated on substrates with lower stiffness (E ∼ 10kPa). Analogously, cells with a stretched cytoplasm/nuclear shape in the border regions of the 3D organoids exhibited a higher YAP nuclear localization level and expression of fibrotic markers compared with cells with a more round geometry in the center of the spheres. To uncouple the cytoskeleton tensioning-dependent YAP nuclear shuttling, we treated CDCs plated onto stiff substrates with blebbistatin and Y27632. This showed a fully reversible YAP relocation from the nucleus to the cytoplasm and a reversion of canonical target genes (CYR61, ANKRD1 and CTGF) expression. In parallel, a “softening” process of the nucleus, likely due to release from cytoskeleton traction forces, was observed by confocal imaging along the cellular z-axis. Interestingly, use of Verteporfin, a drug directly interfering with the interaction of YAP/TAZ complex with TEADs DNA binding proteins showed reversion of pro-fibrotic YAP targets independent of high cytoskeleton tensioning.
Conclusions
These results establish, for the first time, a deterministic relationship between pro-pathologic evolution of human adult cardiac stromal cells and activation of mechanosensing-dependent pathways. They also provide quantitative criteria for interpreting fibrotic evolution of the heart based on modifications of myocardial architecture and mechanical compliance, as well as the ability of the cells to generate tension forces affecting the nuclear structure.

Abstract
Background Treatment options for achalasia include endoscopic and surgical techniques that carry the risk of esophageal bleeding and perforation. The rare coexistence of esophageal varices has only been anecdotally described and treatment is presumed to carry additional risk. Methods Experience from physicians/surgeons treating this rare combination of disorders was sought through the International Manometry Working Group. Results Fourteen patients with achalasia and varices from seven international centers were collected (mean age 61 ± 9 years). Five patients were treated with botulinum toxin injections (BTI), four had dilation, three received peroral endoscopic myotomy (POEM), one had POEM then dilation, and one patient underwent BTI followed by Heller's myotomy. Variceal eradication preceded achalasia treatment in three patients. All patients experienced a significant symptomatic improvement (median Eckardt score 7 vs 1; p < 0.0001) at 6 months follow-up, with treatment outcomes resembling those of 20 non-cirrhotic achalasia patients who underwent similar therapy. No patients had recorded complications of bleeding or perforation. Conclusion This study shows an excellent short-term symptomatic response in patients with esophageal achalasia and varices and demonstrates that the therapeutic outcomes and complications, other than transient encephalopathy in both patients who had a portosystemic shunt, did not differ to disease-matched patients without varices.

Abstract
Preclinical and clinical evidences have demonstrated that astroglial-derived S100B protein is a key element in neuroinflammation underlying the pathogenesis of Parkinson's disease (PD), so much as that S100B inhibitors have been proposed as promising candidates for PD targeted therapy. Pentamidine, an old-developed antiprotozoal drug, currently used for pneumocystis carinii is one of the most potent inhibitors of S100B activity, but despite this effect, is limited by its low capability to cross blood brain barrier (BBB). To overcome this problem, we developed a non-invasive intranasal delivery system, chitosan coated niosomes with entrapped pentamidine (inPentasomes), in the attempt to provide a novel pharmacological approach to ameliorate parkinsonism induced by subchronic MPTP administration in C57BL-6 J mice. inPentasomes, prepared by evaporation method was administered daily by intranasal route in subchronic MPTP-intoxicated rodents and resulted in a dose-dependent manner (0.001-0.004 mg/kg) capable for a significant Tyrosine Hydroxylase (TH) positive neuronal density rescue in both striatum and substantia nigra of parkinsonian mice. In parallel, inPentasomes significantly decreased the extent of glial-related neuroinflammation through the reduction of specific gliotic markers (Iba-1, GFAP, COX-2, iNOS) with consequent PGE2 and NO2- release reduction, in nigrostriatal system. inPentasomes-mediated S100B inhibition resulted in a RAGE/NF-κB pathway downstream inhibition in the nigrostriatal circuit, causing a marked amelioration of motor performances in intoxicated mice. On the basis of our results, chitosan coated niosomes loaded with pentamidine, the inPentasome system, self-candidates as a promising new intranasal approach to mitigate parkinsonism in humans and possibly paves the way for a possible clinical repositioning of pentamidine as anti-PD drug.

Abstract
There is high confidence that the anthropogenic increase of atmospheric greenhouse gases (GHGs) is causing modifications in the Earth's climate. Coastal waterbodies such as estuaries, bays and lagoons are among those most affected by the ongoing changes in climate. Being located at the land-sea interface, such waterbodies are subjected to the combined changes in the physical-chemical processes of atmosphere, upstream land and coastal waters. Particularly, climate change is expected to alter phytoplankton communities by changing their environmental drivers (especially climate-related), thus exacerbating the symptoms of eutrophication events, such as hypoxia, harmful algal blooms (HAB) and loss of habitat. A better understanding of the links between climate-related drivers and phytoplankton is therefore necessary for projecting climate change impacts on aquatic ecosystems. Here we present the case study of the Zero river basin in Italy, one of the main contributors of freshwater and nutrient to the salt-marsh Palude di Cona, a coastal waterbody belonging to the lagoon of Venice. To project the impacts of climate change on freshwater inputs, nutrient loadings and their effects on the phytoplankton community of the receiving waterbody, we formulated and applied an integrated modelling approach made of: climate simulations derived by coupling a General Circulation Model (GCM) and a Regional Climate Model (RCM) under alternative emission scenarios, the hydrological model Soil and Water Assessment Tool (SWAT) and the ecological model AQUATOX. Climate projections point out an increase of precipitations in the winter period and a decrease in the summer months, while temperature shows a significant increase over the whole year. Water discharge and nutrient loads simulated by SWAT show a tendency to increase (decrease) in the winter (summer) period. AQUATOX projects changes in the concentration of nutrients in the salt-marsh Palude di Cona, and variations in the biomass and species of the phytoplankton community.

Abstract
Saliva collection is considered a non-invasive method to detect inflammatory markers in response to emotional states within natural social contexts. Numerous studies have prompted an important role of cytokines in modulating distinct aspects of social and emotional behavior. The aim of this study was to investigate the reliability of plasma and saliva as investigative tools for measure some inflammatory marker levels (CRP, IL-1β, IL-18, and IL-6). At the same time, the relationships between these markers and emotional states in response to a socio-cognitive stress (Academic Exam, AE), were considered. It was demonstrated that the plasma and saliva concentrations of all immune-mediators analyzed were significantly related across the socio-cognitive stress. In addition, when there was a close correlation to AE, the anger state, the IL-1β, the IL-18 salivary and plasmatic concentrations were significantly higher, while they decreased during the AE. On the other hand, the anxiety state and the IL-6 levels significantly increased throughout the AE. The IL-1β and IL-6 were positively associated to the anger and the anxiety state, respectively. In conclusion, our data highlight that different immune markers are similarly detectable in plasma and saliva during socio-cognitive stress. Also, they could be related to different emotional responses.

Abstract
OBJECTIVES In our previous reports, we have demonstrated that extremely low-frequency electromagnetic fields (ELF-EMF) exposure enhances the proliferation of keratinocyte. The present study aimed to clarify effects of ELF-EMF on wound healing and molecular mechanisms involved, using a scratch in vitro model. MATERIALS AND METHODS The wounded monolayer cultures of human immortalized keratinocytes (HaCaT), at different ELF-EMF and Sham exposure times were monitored under an inverted microscope. The production and expression of IL-1β, TNF-α, IL-18 and IL-18BP were measured by enzyme-linked immunosorbent assay and quantitative real-time PCR. The activity and the expression of matrix metalloproteinases (MMP)-2/9 was evaluated by zymography and Western blot analysis, respectively. Signal transduction proteins expression (Akt and ERK) was measured by Western blot. RESULTS The results of wound healing in vitro assay revealed a significant reduction of cell-free area time-dependent in ELF-EMF-exposed cells compared to Sham condition. Gene expression and release of cytokines analysed were significantly increased in ELF-EMF-exposed cells. Our results further showed that ELF-EMF exposure induced the activity and expressions of MMP-9. Molecular data showed that effects of ELF-EMF might be mediated via Akt and ERK signal pathway, as demonstrated using their specific inhibitors. CONCLUSIONS Our results highlight ability of ELF-EMF to modulate inflammation mediators and keratinocyte proliferation/migration, playing an important role in wound repair. The ELF-EMF accelerates wound healing modulating expression of the MMP-9 via Akt/ERK pathway.

Abstract
Neural cells are the smallest building blocks of the central and peripheral nervous systems. Information in neural networks and cell-substrate interactions have been heretofore studied separately. Understanding whether surface nano-topography can direct nerve cells assembly into computational efficient networks may provide new tools and criteria for tissue engineering and regenerative medicine. In this work, we used information theory approaches and functional multi calcium imaging (fMCI) techniques to examine how information flows in neural networks cultured on surfaces with controlled topography. We found that substrate roughness S a affects networks topology. In the low nano-meter range, S a = 0-30 nm, information increases with S a . Moreover, we found that energy density of a network of cells correlates to the topology of that network. This reinforces the view that information, energy and surface nano-topography are tightly inter-connected and should not be neglected when studying cell-cell interaction in neural tissue repair and regeneration.

Abstract
Breast cancer is the most common female cancer in Western populations, affecting 12.5% of women, with 1.38 million patients per year. Breast-conserving surgery followed by postoperative radiotherapy replaced the radical and modified-radical procedures of Halsted and Patey as the standard of care for early-stage breast cancer once the overall and disease-free survival rates of breast-conserving surgery were demonstrated to be equivalent to those of mastectomy. However, excision of >20% of breast tissue, low or centrally located cancer, and large-sized breasts with various grades of breast ptosis, result a in unacceptable cosmetic outcomes. Oncoplastic breast surgery evolved from the breast-conserving surgery by broadening its general indication to achieve wider excision margins without compromising on the cosmetic outcomes. Thus, oncoplastic breast surgery can be defined as a tumor-specific immediate breast reconstruction method that applies aesthetically derived breast reduction techniques to the field of breast cancer surgery and allows for higher volume excision with no aesthetic compromise. However, contralateral breast symmetrization should be regarded as an intrinsic component of the oncoplastic surgery. The main procedures involved are volume-displacement or volume-replacement techniques, which depend on breast size and cancer size/location. Volume-displacement or reshaping procedures apply the plastic surgery principles to transpose a dermo-glandular flap of breast tissue into the defect site, while volume-replacement techniques use autologous tissues to replace the volume loss that follows tumor resection. Furthermore, these procedures are more complex and time-consuming than those involved in breast-conserving surgery. Based on current literature, the authors analyze the different techniques and indications of the oncoplastic breast surgery, determining its complication rate, in order to help both surgeons and their patients in the decision-making stage of breast reconstruction.

Abstract
INTRODUCTION In patients with gastroesophageal reflux disease (GORD), co-existence of functional dyspepsia (FD) is known to be associated with poor response to proton pump inhibitors (PPIs), but the contribution of specific dyspepsia symptoms has not yet been systematically investigated. OBJECTIVE We aimed to characterize the impact of dyspepsia symptoms on response to PPIs in patients with GORD. METHODS The enrolled subjects were consecutive patients with a diagnosis of GORD. All patients underwent a 24 hour pH-impedance test, while on PPI therapy. Patients were divided into two groups, refractory and responders, according to the persistence of GORD symptoms. A standardized questionnaire for FD was also administered to assess presence of dyspepsia symptoms. RESULTS In the subgroup of refractory patients FD was more prevalent than in responders, with post-prandial fullness, nausea, vomiting, early satiation and epigastric pain being significantly prevalent in refractory GORD patients. In the multivariate analysis only early satiation and vomiting were significantly associated with poor response to PPIs. CONCLUSION Co-existence of FD is associated with refractory GORD. We showed that only early satiation and vomiting are risk factors for poor response to therapy with PPIs. Our findings suggest that symptoms of early satiation and vomiting would help to identify the subset of PPI-refractory GORD patients.

Abstract
Pluripotency and commitment are driven by transcription factors that act as molecular switches to activate or repress specific gene expression programs. Among these, the POU transcription factor OCT4 (encoded by POU class 5 homeobox 1, POU5F1) is known to be a regulator in pluripotent cells and it is essential for the maintenance of a high plasticity state in mammalian cells. In recent years, particular attention has been given to the importance of physical extracellular matrix properties in regulating pluripotent cell maintenance and differentiation. In particular, recent studies demonstrated that high plasticity cells are intrinsically soft and respond optimally to physical forces when cultured on a “low stiffness” substrate that matches their intrinsic softness. To investigate these aspects, here we used a protocol where terminally differentiated cells are driven into a high plasticity/OCT4-positive state through the use of the epigenetic eraser, 5-aza-cytidine (5-aza-CR) and we observed the effect of substrate stiffness on the maintenance of OCT4 expression. To this purpose, human skin fibroblasts were plated either on standard plastic dishes (group A) or on polyacrylamide gels (PAA) of low stiffness (1 kPa; group B). Cells were treated with 1 μM 5-aza-CR for 18 h and were subsequently maintained and cultured in embryonic stem cell medium for 14 days. Assessment of OCT4 was carried out both by real-time PCR and immunocytochemical analysis, at different time points: untreated fibroblasts (T0), after 5-aza-CR treatment, and on Days 2, 4, 6, 8, 10, and 14 of culture. The results obtained indicate that untreated fibroblasts (T0) were negative for OCT4, whereas, after 5-aza-CR exposure, cells actively expressed the pluripotency marker, in both the A and B groups. However, whereas group A cells progressively down-regulated OCT4 expression and eliminated its positivity by Day 6, group B cells steadily transcribed and were homogeneously immunopositive for the pluripotency factor until Day 14, when cultures were arrested. Overall, the data obtained suggest that a soft substrate, matching the intrinsic stiffness distinctive of high plasticity cells, may help in promoting their maintenance, via a biophysical mechanism of low-traction/low-stiffness-dependent manner.

Abstract
In addition to the well-known involvement of macrophages and neutrophils, other cell types have been recently reported to substantially contribute to the onset and progression of inflammatory bowel diseases (IBD). Enteric glial cells (EGC) are the equivalent cell type of astrocyte in the central nervous system (CNS) and share with them many neurotrophic and neuro-immunomodulatory properties. This short review highlights the role of EGC in IBD, describing the role played by these cells in the maintenance of gut homeostasis, and their modulation of enteric neuronal activities. In pathological conditions, EGC have been reported to trigger and support bowel inflammation through the specific over-secretion of S100B protein, a pivotal neurotrophic factor able to induce chronic inflammatory changes in gut mucosa. New pharmacological tools that may improve the current therapeutic strategies for inflammatory bowel diseases (IBD), lowering side effects (i.e. corticosteroids) and costs (i.e. anti-TNFα monoclonal antibodies) represent a very important challenge for gastroenterologists and pharmacologists. Novel drugs capable to modulate enteric glia reactivity, limiting the pro-inflammatory release of S100B, may thus represent a significant innovation in the field of pharmacological interventions for inflammatory bowel diseases.

Abstract
Heart failure (HF) is a common clinical syndrome with frequent exacerbations requiring hospitalization. Among the various mechanisms that underlie the pathogenesis of HF, the activation of the immune system leads to a progressive and redundant release of proinflammatory cytokines responsible for a variety of deleterious effects in heart failure, such as endothelial dysfunction, apoptosis of myocytes, activation of MMPs (Matrix Metallo Proteinases) and oxidative stress, with the result of decreased inotropism and clinical syndrome such as pulmonary edema,. The condition of oxidative stress induces the expression of genes coding for the proteins inducible nitric oxide synthase (iNOS) and heme oxygenase-1 (HO-1). Twenty-five hospitalized cardiology patients with symptomatic acute congestive HF (NYHA Class III-IV) and impaired left ventricular (LV) function (ejection fraction less than 35 percent) were included in the study. The aim of this study was to evaluate the cytokines plasma concentrations and the expression and activity of iNOS and HO-1 proteins in peripheral blood mononuclear cell (PBMC) extracted from patients in comparison to control group. In ACHF; left ventricular ejection fraction (LVEF) percent was reduced. Furthermore; iNOS and HO-1 expression and cytokines plasma levels were significantly higher in patients with ACHF as compared to controls group. Moreover the enzyme activity presents an opposite trend compared to that obtained in the analysis of the transcript and proteins. Our studies suggest a negative feedback interaction between iNOS and HO-1 important in the physiopathology of heart failure that could be considered a good candidate as a future therapeutic target for the development of new drugs.

Abstract
During the past decade, a great deal of data has accumulated supporting the notion that cytokines interact to regulate several aspects of social and emotional behaviour. There are reports of a positive correlation between cytokine levels and aggressive behaviour in healthy populations, and clinical reports describe an increase of aggressive traits in patients who receive cytokine immunotherapy. Interleukin-1beta released during an immune response acts as messenger that helps to modulate behaviour by influencing relevant neurotransmitter systems, and in some cases, by directly acting within the brain. In this site, IL-1beta exerts its actions by acting through 5-HT2 and IL-1 Type I receptors in hypothalamus or by potentially indirect routes, including activation of sensory afferents, and stimulation of cytokine release by brain endothelial cells. This review reports research investigating the relationship between IL-1beta, and the immune and central nervous systems involving or potentially involving defensive aggressive behaviour.

Abstract
BACKGROUND Extremely low frequency (ELF) electromagnetic fields (EMF) are known to produce a variety of biological effects. Clinical studies are ongoing using EMF in healing of bone fractures and skin wounds. However, little is known about the mechanisms of action of ELF-EMF. Several studies have demonstrated that expression and regulation of nitric oxide synthase (NOS) and cyclooxygenase-2 (COX-2) are vital for wound healing; however, no reports have demonstrated a direct action of ELF-EMF in the modulation of these inflammatory molecules in human keratinocytes. OBJECTIVES The present study analysed the effect of ELF-EMF on the human keratinocyte cell line HaCaT in order to assess the mechanisms of action of ELF-EMF and to provide further support for their therapeutic use in wound healing. METHODS Exposed HaCaT cells were compared with unexposed control cells. At different exposure times, expression of inducible NOS (iNOS), endothelial NOS (eNOS) and COX-2 was evaluated by Western blot analysis. Modulation of iNOS and eNOS was monitored by evaluation of NOS activities, production of nitric oxide (NO) and O(2)(-) and expression of activator protein 1 (AP-1). In addition, catalase activity and prostaglandin (PG) E(2) production were determined. Effects of ELF-EMF on cell growth and viability were monitored. RESULTS The exposure of HaCaT cells to ELF-EMF increased iNOS and eNOS expression levels. These ELF-EMF-dependent increased expression levels were paralled by increased NOS activities, and increased NO production. In addition, higher levels of AP-1 expression as well as a higher cell proliferation rate were associated with ELF-EMF exposure. In contrast, ELF-EMF decreased COX-2 expression, PGE(2) production, catalase activity and O(2)(-) production. CONCLUSIONS Mediators of inflammation, such as reactive nitrogen and PGE(2), and keratinocyte proliferation are critical for the tissue regenerative processes. The ability of ELF-EMF to upmodulate NOS activities, thus nitrogen intermediates, as well as cell proliferation, and to downregulate COX-2 expression and the downstream intermediate PGE(2), highlights the potential therapeutic role of ELF-EMF in wound healing processes.

Abstract
Verbascum mallophorum is part of a large family of Scrophulariaceae consisting of more than 360 species. Verbascum mallophorums contains diverse polysaccharides, iroid glycosides, flavonoids, saponins, volatile oils and phenylentanoids. Verbascum has been used in popular medicine for treating wounds, chilblains, respiratory ailments, acne and arthritic disturbances. Inducible nitric oxide synthase (iNOS) represents one of the three isoforms that produce nitric oxide using L-arginine as a substrate in response to an increase in superoxide anion activated by NF-kappaB. It is implicated in different pathophysiological events and its expression increases greatly during an inflammatory process due to oxidative stress. In our study we reproduced an inflammatory state by treating THP-1 cells (human myelomonocytic leukaemia) with pro-inflammatory stimuli, such as LPS and IFN-gamma, obtaining an up-regulation both in the expression and in the activity of iNOS. The aim of our work is to investigate the possible antiinflammatory action of verbascoside extract from Verbascum mallophorum using a concentration of 100 muM. Our results show a significant decrease in the expression and activity of iNOS and extracellular O2- when cells were treated with verbascoside. Based on these results we hypothesize that verbascoside extract from Verbascum mallophorum has anti-inflammatory properties since it reduces the production of superoxide radicals and consequently reduces the activity of iNOS.

Abstract
Erectile dysfunction (ED) is a common medical condition that affects the sexual life of millions of men worldwide. Numerous physical and psychological factors are involved in normal erectile function, including neurological, vascular, hormonal and cavernous functions. The current therapy for the condition is pharmacological and psychotherapeutic which regulates the erectile function and amplifies the NO-mediated response. The aim of this work is to test the action of three common phosphodiesterase inhibitors: Tadalafil, Sildenafil Citrate and Vardenafil at 0.05 microM on human monocytes, analyzing the expression of iNOS protein and mRNA by Western blot and rt-PCR, and production of NO by conversion of L-(2,3,4,5)-[3H]Arginine to L-(3H) citrulline. We also tested the efficiency of the antioxidant network by spectrophotometer (SOD, CAT, GPx and Gr), under normal conditions and after stimulation with LPS. The results showed an increase in ROS levels, similar for all the molecules with regard to the antioxidant enzymes. In all cases the treatment determines a response to the limited efficiency, arriving at a situation in which phosphodiesterase inhibitors + LPS clearly show oxidative stress.

Abstract
In previous in vitro studies we found that contact between mouse primordial germ cells and other cell types (neighbouring somatic cells or established TM4 or STO cell lines) is crucial for supporting primordial germ cell survival and proliferation and for activating their motility. We have studied primordial germ cell adhesion to different cell monolayers (STO, TM4, COS and F9 cells) as an in vitro model for interactions between primordial germ cells and cellular substrates. The results suggest that these cell interactions are mediated by multiple mechanisms involving Steel factor and its receptor encoded by c-kit, carbohydrates and possibly other unknown factors. We find that Steel factor and leukaemia inhibitory factor are survival rather than proliferation factors for primordial germ cells. Both molecules prevent primordial germ cell death in culture by suppressing apoptosis. Morphological and molecular features of primordial germ cell apoptosis in vitro are reported. Activation of protein kinase C does not promote primordial germ cell proliferation, but compounds known to enhance intracellular levels of cAMP (i.e. dibutyryl cAMP and forskolin) markedly stimulate primordial germ cells to proliferate in culture. We have preliminary results indicating that neuropeptides PACAP-27 and PACAP-28 are possible physiological activators of adenylate cyclase in primordial germ cells.

Abstract
Free radical damage to many cellular components has been proposed as the main mechanism underlying the aging process. In the liver, NO can be generated by iNOS, but also by the constitutively expressed endothelial NOS (eNOS). iNOS enzyme appears to be expressed in liver disease such as cirrhosis and fulminant hepatitis, while the eNOS is expressed in physiological conditions. Ten young and ten old Wistar rats were sacrificed and their livers were excised. Liver sections were incubated with an anti-iNOS antibody of rabbit origin. RT-PCR and Western blot analysis were performed and nitric oxide activity was calculated. A significant increase of iNOS immunoreactivity was seen in the aged liver sections versus young liver sections. iNOS protein is expressed in greater quantities in the aged group, compared to the young group. In this study we show, for the first time, that aging in the rat liver is accompanied by a spontaneous induction of iNOS mRNA, high levels of iNOS protein and immunohistochemistry/image analysis.

Abstract
In this paper we examined the variations of plasmatic concentrations of hypoxanthine and xanthine, and their relation with other important indicators of muscular stress creatine-kinase (CK), myoglobin, uric acid, leucocytes, in prolonged, isokynetic physical exercise, performed in a concentric mode at different joint excursion. Twenty healthy male subjects performed isokinetic exercises in concentric-concentric mode, with joint excursion of 30, 60, 90 deg/sec. Blood samples were drawn at rest, immediately after exercise and after 45 min of recovery. The plasmatic concentration of hypoxanthine increased at the end of physical exercise, compared to the rest value of about 1,5 micromol/L, up to a level of greater than 19 micromol/L; the values were higher after a period of recovery of 45 min and the increase varies considerably according to the type of exercise that was performed. Myoglobin has a slight but sensible increment too, with the same trend as hypoxanthine, while CK increase without correlation to the type of exercises. The relation with other indicators of muscular activity demonstrates that in none of the different isokinetic exercises, performed at concentric mode, was there ultrastructural damage, while it is possible to come across a considerable metabolic stress, which is dissimilar in the different kinds of exercises. The results suggest that hypoxanthine can be useful in monitoring the effectiveness of a work load and the metabolic stress consequences on the muscle tissue in training or rehabilitation programs. The results also suggest that even myoglobin, at small concentrations, can have the same function.

Abstract
OBJECTIVE To prepare a website for families and health professionals containing up to date information about paediatric rheumatic diseases (PRD). METHODS Firstly, paediatric rheumatology centres and family self help associations were surveyed to characterise current clinical practice of physicians providing care for children with PRD, research activities, and training facilities of each centre. Secondly, international consensus was reached on the content of the website. Finally, the website was developed and the texts translated. RESULTS The web page contains three main sections: (a) description for families of the characteristics of 15 PRD; (b) list of paediatric rheumatology centres; (c) contact information for family self help associations. A version for 45 countries in 52 languages (with another three in progress) is now available on the web. 291 surveys from 171 centres and 102 family associations were received from 42 countries. The median proportion of time spent in paediatric practice in the centres examined was 100%, with 70% of this time dedicated to paediatric rheumatology. 90% of the centres were willing to perform clinical trials in the future. CONCLUSIONS The PRINTO/PRES website provides a well defined and competent set of information about PRD, with appropriate multiple translated versions and easy web navigational direction.

Abstract
We report the case of a 60-year-old man with patent coronary by-pass grafts on the left anterior descending and circumflex coronary arteries, who experienced recurrent Canadian class IV angina refractory to medical and interventional treatments for a dominant right coronary artery occlusion. He underwent autologous PBSC transplant into the inferior ventricular wall through a minimally invasive approach as a stand-alone therapy, in an attempt to induce therapeutic angiogenesis. Six months after the operation, angina significantly ameliorated; scintigraphy and coronary angiography showed a marked improvement in perfusion of the target injection area. These benefits had persisted at 25 months after stem cell transplant.

Abstract
The Oct-4 POU transcription factor is expressed in mouse totipotent embryonic stem and germ cells. Differentiation of totipotent cells to somatic lineages occurs at the blastocyst stage and during gastrulation, simultaneously with Oct-4 downregulation. Stem cell lines derived from the inner cell mass and the epiblast of the mouse embryo express Oct-4 only if undifferentiated. When embryonic stem cells are triggered to differentiate, Oct-4 is downregulated thus providing a model for the early events linked to somatic differentiation in the developing embryo. In vivo mutagenesis has shown that loss of Oct-4 at the blastocyst stage causes the cells of the inner cell mass to differentiate into trophectoderm cells. Recent experiments indicate that an Oct-4 expression level of roughly 50%-150% of the endogenous amount in embryonic stem cells is permissive for self-renewal and maintenance of totipotency. However, upregulation above these levels causes stem cells to express genes involved in the lineage differentiation of primitive endoderm. These novel advances along with latest findings on Oct-4-associated factors, target genes, and dimerization ability, provide new insights into the understanding of the early steps regulating mammalian embryogenesis.

Abstract
Oct-4 is a transcription factor that is specifically expressed in mouse embryonic stem cells and in cell lines derived thereof. In these cells, Oct-4 activates transcription from remote binding sites due to as of yet unknown co-activators. Expression of Oct-4 in differentiated cells is not sufficient to activate transcription from a distance, rather it requires the co-expression of co-activators such as the adenoviral oncoprotein E1A. In this paper, we used phage display to identify Oct-4-interacting proteins. We first analyzed the interaction between Oct-4 and E1A in order to optimize the biochemical conditions that enable Oct-4-specific interactions with other interacting proteins. A panning approach was used to enrich Oct-4 interacting phages from a pool of excess unspecific phages. The biochemical conditions established in our interaction assays were then used to screen a P19 EC cell cDNA expression library in M13 filamentous phage. A number of phage clones displaying portions of unknown and known transcription factors were obtained, from which the HMG-1 transcription factor was identified. HMG-1, and the closely related factor HMG-2, interact with Oct-4 when co-expressed in mammalian cells. In addition, HMG-1 was found to cooperate with Oct-4 in P19 EC cells. These results provide the first evidence of a non-viral factor that enhances Oct-4 distance-dependent transactivation in stem cells.

Abstract
The object of this investigation was to demonstrate that the enhanced sensitivity of the diagnosis of acute myocardial infarction (AMI) using a more-inclusive criterion of CKMB Isoforms may detect earlier stages of AMI (designated Isoform Type 2) than the currently accepted marker for AMI by CKMB Isoform (designated Isoform Type 1) in a busy, urban Emergency Department (ED). Two features characterized the study of CKMB Isoforms in a prospective cohort of 223 ED patients: first, nontraumatic chest pain within 12 h before presentation, thought to be of ischemic etiology; and second, normal or nondiagnostic electrocardiogram (EKG). Patients were further divided into two groups characterized as either recent but resolved chest pain at ED visit, or ongoing or staccato chest pain. Sensitivity (S), specificity (SP), positive (PPV) and negative (NPV) predictive values, and 95% confidence intervals (CI) for AMI diagnosis were determined. Two criteria for AMI diagnosis by CKMB Isoforms were tested. The first and currently recommended criterion was identified as Isoform Type 1. An AMI diagnosis by Type 1 criterion requires both CKMB2> or =2.6 IU/L and CKMB2/CKMB1> or =1.7. The second criterion for AMI diagnosis was identified as Isoform Type 2, which is defined as either CKMB2> or =2.6 IU/L or CKMB2/CKMB1> or =1.7. Both Isoform types are predictive of AMI by the gold standard, and addition of EKG changes results in a small improvement. Type 1 demonstrates SP 0.94 (CI 0.90, 0.97) and NPV 0.90 (CI 0.86, 0.94), and Type 2 demonstrates S 0.90 (CI 0.80, 0.97) and NPV 0.97 (CI 0.93, 0.99) for AMI diagnosis. Type 2 criteria can confidently exclude the immediate risk of AMI in patients with resolved chest pain whereas in patients with continuous chest pain, Type 1 criteria may identify those at high risk for AMI.

Abstract
The transcription factor Oct-4 is expressed in totipotent embryonic cells and germ cells. As totipotent cells differentiate to form somatic and/or extraembryonic tissues, the Oct-4 gene is downregulated. Primordial germ cells are the only cells in which Oct-4 expression is maintained after postgastrulation. Recent in vivo ablation of the Oct-4 function has shown that the absence of this transcription factor causes early embryonic lethality due to trophectodermal differentiation of cells which normally would give rise to the inner cell mass of the blastocyst. This result strongly suggests that Oct-4 is necessary for the maintenance of the totipotent phenotype of embryonic cells and that this factor likely plays a role as a determinant of the totipotency of germ cells by preventing their differentiation to a somatic cell phenotype during gastrulation. The involvement of Oct-4 in the biology of totipotent and germ cells is here discussed in view of new understanding about Oct-4 function.

Abstract
Laboratory bioassays and field trials were carried out to study the effect of metallic copper on the development of Aedes albopictus (Skuse). Multiwire electric cable was used as a source of metallic copper. Three different doses were used in laboratory tests (5, 10, and 20 g/liter) and two in field tests (20 and 40 g/liter). In the laboratory, 10 g/liter induced high mortality and a lack of development in Ae. albopictus larvae and doses of 20 g/liter completely inhibited development. Larval mortality was higher in earlier instars than in third through fourth instars and pupae. No effects were reported on egg hatching. Copper ion concentration in water increased up to 574 ppb for 5 g/liter dose, 710 ppb for 10 g/liter dose, and 1,210 ppb for 20 g/liter dose, within week 6. The increasing concentration of copper in water was correlated positively with the decreasing production of adults. Copper ions concentration < 500 ppb did not or only slightly affected larval development and mortality of Ae. albopictus in laboratory tests. Copper concentrations between 500 and 1,000 ppb delayed larval development and caused high mortality. Copper concentrations > 1,000 ppb inhibited larval development completely killing all the larvae. This last result has been achieved by the use of a 20 g/liter dose of metallic copper in water. Copper also affected adult weight. In field trials, 20 g/liter reduced the number of larvae in treated pots by 90%, and 40 g/liter completely prevented oviposition. Moreover, the persistence of the toxic action of metallic copper in the field lasted for several months.
