Abstract
OBJECTIVES To report epidemiological and virological results of an outbreak investigation of influenza-like illness (ILI) among refugees in Northern Italy. STUDY DESIGN Outbreak investigation of ILI cases observed among nearly 100 refugees in Northern Italy unvaccinated for influenza. METHODS An epidemiological investigation matched with a differential diagnosis was carried out for each sample collected from ILI cases to identify 10 viral pathogens (SARS-CoV-2, influenza virus type A and B, respiratory syncytial virus, metapneumovirus, parainfluenza viruses, rhinovirus, enterovirus, parechovirus, and adenovirus) by using specific real-time PCR assays according to the Centers for Disease Control and Prevention (CDC) protocols. In cases where the influenza virus type was identified, complete hemagglutinin (HA) gene sequencing and the related phylogenetic analysis were conducted. RESULTS The outbreak was caused by influenza A(H3N2): the attack rate was 83.3% in children aged 9-14 years, 84.6% in those aged 15-24 years, and 28.6% in adults ≥25 years. Phylogenetic analyses uncovered that A(H3N2) strains were closely related since they segregated in the same cluster, showing both a high mean nucleotide identity (100%), all belonging to the genetic sub-group 3C.2a1b.2a.2, as those mainly circulating into the general population in the same period. CONCLUSIONS The fact that influenza outbreak strains as well as the community strains were genetically related to the seasonal vaccine strain suggests that if an influenza prevention by vaccination strategy had been implemented, a lower attack rate of A(H3N2) and ILI cases might have been achieved.

Abstract
Granular cell tumors of the neurohypophysis (GCT) are rare benign neoplasms belonging, along with pituicytoma and spindle cell oncocytoma, to the family of TTF1-positive low-grade neoplasms of the posterior pituitary gland. GCT usually present as a solid sellar mass, slowly growing and causing compressive symptoms over time, occasionally with suprasellar extension. They comprise polygonal monomorphous cells with abundant granular cytoplasm, which is ultrastructurally filled with lysosomes. Here we report the case of a GCT presenting as a third ventricle mass, radiologically mimicking chordoid glioma, with aberrant expression of GFAP and Annexin-A, which lends itself as an example of an integrated diagnostic approach to sellar/suprasellar and third ventricle masses.

Abstract
Aim: Bibliometric surveys are time-consuming endeavors, which cannot be scaled up to meet the challenges of ever-expanding fields, such as bone regeneration. Artificial intelligence, however, can provide smart tools to screen massive amounts of literature, and we relied on this technology to automatically identify research topics. Materials & methods: We used the BERTopic algorithm to detect the topics in a corpus of MEDLINE manuscripts, mapping their similarities and highlighting research hotspots. Results: Using BERTopic, we identified 372 topics and were able to assess the growing importance of innovative and recent fields of investigation such as 3D printing and extracellular vescicles. Conclusion: BERTopic appears as a suitable tool to set up automatic screening routines to track the progress in bone regeneration.

Abstract
AbstractA literature search on the in vitro testing of anti-inflammatory compounds of natural origin revealed a considerable number of studies adopting a similar template for data reporting in the years up to 2019. Sixty-five such reports appear to have been published between the years 2008 and 2019. Interestingly, this format template was clearly recognizable by a few hallmarks, such as a precise way of plotting cell viability data, extremely consistent endpoints, and the way these were graphically represented. In some instances the similarities extended to some textual features, such as in the case of figure legends. The similarity was so high that chance can be excluded and these studies can be safely assumed to have intentionally followed a template. By 2020, however, no new reports following this format have been published. Although a consistent and reproducible formatting for data reporting may improve report readability, this phenomenon should also be closely scrutinized to assess the rationale why it occurred, the validity of the endpoints that were chosen and why it was then abandoned. The present report reviewed the mean features of this format, traced its origin and its evolution over time, while discussing the limitations of this model.

Abstract
Following a request from five European Nordic countries, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was tasked to provide scientific advice on a tolerable upper intake level (UL) or a safe level of intake for dietary (total/added/free) sugars based on available data on chronic metabolic diseases, pregnancy-related endpoints and dental caries. Specific sugar types (fructose) and sources of sugars were also addressed. The intake of dietary sugars is a well-established hazard in relation to dental caries in humans. Based on a systematic review of the literature, prospective cohort studies do not support a positive relationship between the intake of dietary sugars, in isocaloric exchange with other macronutrients, and any of the chronic metabolic diseases or pregnancy-related endpoints assessed. Based on randomised control trials on surrogate disease endpoints, there is evidence for a positive and causal relationship between the intake of added/free sugars and risk of some chronic metabolic diseases: The level of certainty is moderate for obesity and dyslipidaemia (> 50-75% probability), low for non-alcoholic fatty liver disease and type 2 diabetes (> 15-50% probability) and very low for hypertension (0-15% probability). Health effects of added vs. free sugars could not be compared. A level of sugars intake at which the risk of dental caries/chronic metabolic diseases is not increased could not be identified over the range of observed intakes, and thus, a UL or a safe level of intake could not be set. Based on available data and related uncertainties, the intake of added and free sugars should be as low as possible in the context of a nutritionally adequate diet. Decreasing the intake of added and free sugars would decrease the intake of total sugars to a similar extent. This opinion can assist EU Member States in setting national goals/recommendations.

Abstract
The success of invitro embryo production (IVEP) in horses has increased considerably during recent years, but little is known about the effect of the speed of invitro embryo development. Blastocysts (n=390) were produced by intracytoplasmic sperm injection of IVM oocytes from warmblood mares, cryopreserved, thawed and transferred into recipient mares on Days 3, 4, 5 or 6 after ovulation. The time required for invitro-produced (IVP) embryos to reach the blastocyst stage was recorded (Day 7 vs Day 8). The likelihood of foaling was affected by the speed of invitro embryo development and recipient day after ovulation at transfer. The odds ratio for foaling was ~0.63 for transfer of Day 8 (46%) compared with Day 7 (56%) IVP blastocysts. The highest likelihood of pregnancy (72%) and foaling (60%) was observed when IVP blastocysts were transferred to recipient mares on Day 4 after ovulation. Finally, the sex (colt:filly) ratio was higher after transfer of Day 7 (71%:29%) than Day 8 (54%:46%) IVP blastocysts, suggesting that the speed of embryo development is sex dependent. In conclusion, the speed of invitro embryo development in our IVEP system affects the likelihood of foaling and the sex of the foal.

Abstract
BACKGROUND HIV infection is a major health problem in Russia. We aimed to assess HIV prevalence in different population groups and to compare the characteristics of 4th generation immunoassays from Abbott, Bio-Rad, Vector-Best, Diagnostic Systems, and Medical Biological Unit. METHODS The study included 4452 individuals from the general population (GP), 391 subjects at high risk of HIV infection (HR) and 699 with potentially interfering conditions. HIV positivity was confirmed by immunoblot and by HIV RNA, seroconversion and virus diversity panels were also used. HIV avidity was employed to assess recent infections. RESULTS The prevalence in GP was 0.40%, higher in males (0.62%) and in people aged < 40 years (0.58%). Patients attending dermo-venereal centers and drug users had a high prevalence (34.1 and 58.8%). Recent infections were diagnosed in 20% of GP and in 4.2% of HR. Assay sensitivity was 100% except for one false negative (99,54%, MBU). Specificity was 99.58-99.89% overall, but as low as 93.26% on HR (Vector-Best). Small differences on early seroconversion were recorded. Only the Abbott assay detected all samples on the viral diversity panel. CONCLUSION HIV infection rate in the high-risk groups suggests that awareness and screening campaigns should be enhanced. Fourth generation assays are adequate but performance differences must be considered.

Abstract
The clinical presentation of symptomatic SARS-CoV-2 not only includes viral pneumonia, but also milder illness overlapping with influenza-like illness (ILI), allowing a potential tracking of the infection in the framework of the national influenza surveillance system (SS). By comparing the data recorded by the influenza SS in 2019-20 season to those collected for the previous years, we want to evaluate whether the implementation of ILI SS could succeed in early detection and monitoring of Covid-19 diffusion. We analyzed the data recorded by the influenza SS and we compared the distribution of ILI incidence rate by week for 2017-18, 2018-19 and 2019-20 season in order to understand whether the SS detected any abnormality coinciding with Covid-19 outbreak. The distribution of ILI cases in the three seasons presented a similar pattern up to the 9th week; after then, a reduction in the ILI incidence rate was observed in the 2017-18 and the 2018-19 season while an increase was detected for 2019-20. During 2019-20 season, three major characteristics stand out: i) at the beginning of Covid-19 epidemic (7th-9th week) 9,17/1000 cases were reported; ii) during the recognition of the COVID-19 outbreak (9th-10th week) 6,36/1000 cases; iii) during the spread of Covid-19 (10th-11th week) an unexpected increase to 7,72/1000 cases. Additionally, their geographical distribution was concentrated in the areas known to be most affected by the epidemic. The influenza SS enabled us to detect the introduction and distribution of COVID-19. Implementation of the system should be prioritized in order to early identify new waves of Covid-19 but also any future novel respiratory pathogen. In order to empower the SS, it would be advisable to increase the population coverage about 2% which is the actual standard.

Upper limb recovery is a complex process and a strong challenge in the rehabilitation of patients after stroke. Several studies have been conducted to compare the efficacy of conventional and robotic rehabilitation to restore the upper limb motor impairment following a stroke. However, the evolution of the upper limb motor ability during an intervention, as well as the time point when the patient stops improving (the so call plateau), are rarely measured, and never compared between the two approaches. These latter aspects are very important considering the need for an optimization of the economic resources. In this study, the time course of the upper limb motor recovery of 24 subacute stroke patients undergoing a 30-session robotic or conventional treatment was analyzed through the upper extremity portion of the Fugl-Meyer Assessment scale (FMA-UE). The FMA-UE was administered before the treatment, and after 10, 20, and 30 rehabilitation sessions. Statistical analysis showed that, according to the FMA-UE, the time course in the two groups was similar: patients did not change between the baseline and the 10-session assessment, while they improved between 10 and 20 sessions, and between 20 and 30 sessions, with most of the gain observed between 10 and 20 sessions. This result suggests that 30-session robotic or conventional rehabilitation programs induce a similar curve trend in the upper limb motor recovery of patients with subacute stroke, with an important increase in the middle of the program and without reaching a clear plateau in the analyzed time interval.

Abstract
Aim: The present study evaluated the effects of polydeoxyribonucleotide (PDRN) on tissue regeneration, paying special attention to the molecular mechanisms that underlie its tissue remodeling actions to better identify its effective therapeutic potential in wound healing. Materials & methods: Strategic searches were conducted through MEDLINE/PubMed, Google Scholar, Scopus, Web of Science and the Cochrane Central Register of Controlled Trials, from their earliest available dates to March 2020. The studies were included with the following eligibility criteria: studies evaluating tissue regeneration, and being an in vitro, in vivo and clinical study. Results: Out of more than 90 articles, 34 fulfilled the eligibility criteria. All data obtained proved the ability of PDRN in promoting a physiological tissue repair through salvage pathway and adenosine A2A receptor activation. Conclusion: Up to date PDRN has proved promising results in term of wound regeneration, healing time and absence of side effects.

Abstract
AIM To describe four novel primary epithelial tumours of the sella with papillary architecture and Thyroid Transcription Factor 1 (TTF-1) expression. METHODS Paraffin-embedded tissue from the four cases and recurrence of patient 1 was investigated with haematoxylin-eosin, special histochemical stains, immunohistochemistry with a broad panel of antibodies and next-generation sequencing. The ultrastructure of one tumour was studied in tissue retrieved from paraffin. RESULTS The lesions occurred in three females aged 20, 26 and 42 years and a male aged 49 years. They presented with signs and symptoms secondary to pituitary stalk compression. Preoperative neuroimaging documented mixed solid and cystic, enhancing sellar masses with suprasellar extension. Histologically, the tumours showed thin papillae lined by a single layer of cytokeratin and TTF-1-positive cuboidal and cylindrical cells with mildly atypical nucleus. Next-generation sequencing performed in three cases did not identify any mutations. The main differential diagnosis included metastasis from lung or thyroid carcinoma, extraventricular choroid plexus papilloma and sellar ependymoma. CONCLUSION We suggest the descriptive term of primary papillary epithelial tumour of the sella (PPETS) for this entity and propose that it could represent the intracranial equivalent of thyroid-like low-grade nasopharyngeal papillary adenocarcinoma. The cell of origin of PPETS remains undetermined although the intense and ubiquitous expression of TTF-1 may suggest a derivation from the infundibulum or ventricular recess. Our study expands the spectrum of sellar TTF-1-positive tumour and challenges the view that they all derive from pituicytes.

Abstract
Surface topography is one of the main factors controlling cell responses on implanted devices and a proper definition of the characteristics that optimize cell behavior may be crucial to improve the clinical performances of these implants. Substrate geometry is known to affect cell shape, as cells try to optimize their adhesion by adapting to the irregularities beneath, and this in turn profoundly affects their activity. In the present study, we cultured murine calvaria MC3T3-E1 cells on surfaces with pillars arranged as hexagons with two different spacings and observed their morphology during adhesion and growth. Cells on these highly ordered substrates attached and proliferated effectively, showing a marked preference for minimizing the inter-pillar distance, by following specific pathways across adjacent pillars and displaying consistent morphological modules. Moreover, cell behavior appeared to follow tightly controlled patterns of extracellular protein secretion, which preceded and matched cells and, on a sub-cellular level, cytoplasmic orientation. Taken together, these results outline the close integration of surface features, extracellular proteins alignment and cell arrangement, and provide clues on how to control and direct cell spatial order and cell morphology by simply acting on inter-pillar spacing.

Abstract
Electromagnetic fields (EMFs) have been proposed as a tool to ameliorate bone formation and healing. Despite their promising results, however, they have failed to enter routine clinical protocols to treat bone conditions where higher bone mass has to be achieved. This is no doubt also due to a fundamental lack of knowledge and understanding on their effects and the optimal settings for attaining the desired therapeutic effects. This review analysed the available in vitro and in vivo studies that assessed the effects of sinusoidal EMFs (SEMFs) on bone and bone cells, comparing the results and investigating possible mechanisms of action by which SEMFs interact with tissues and cells. The effects of SEMFs on bone have not been as thoroughly investigated as pulsed EMFs; however, abundant evidence shows that SEMFs affect the proliferation and differentiation of osteoblastic cells, acting on multiple cellular mechanisms. SEMFs have also proven to increase bone mass in rodents under normal conditions and in osteoporotic animals.

Abstract
Current biomedical research is centered on the study of nanomaterials and their effects in biological environments. In particular, there is an increasing interest on TiO₂ nanostructures for biomedical applications such as drug delivery or implant materials. In this framework, we present a Chemical Vapour Deposition process to synthesize titanium dioxide nanowires (NWs) on a commercially pure titanium substrate and we test the material In Vitro as a culture substrate for murine osteoblast-like MC3T3-E1 cells. A physical-morphological, structural and optical-characterization of the inorganic samples is performed by Electron Microscopy techniques and X-ray Diffraction, showing that a mat of crystalline rutile TiO₂ NWs is obtained over the commercial substrate. In Vitro biological tests are performed by seeding MC3T3-E1 cells on the material and studying cell morphology, the cellmaterial interface and the osteoblast gene expression. These experiments show good cell adhesion to the nano-structured surface and a higher degree of early osteoblastic differentiation compared to control titanium surfaces, indicating that the present nano-structured material has good osteogenic potential for biomedical applications.

Abstract
Electromagnetic fields (EMFs) have long been known to interact with living organisms and their cells and to bear the potential for therapeutic use. Among the most extensively investigated applications, the use of Pulsed EMFs (PEMFs) has proven effective to ameliorate bone healing in several studies, although the evidence is still inconclusive. This is due in part to our still-poor understanding of the mechanisms by which PEMFs act on cells and affect their functions and to an ongoing lack of consensus on the most effective parameters for specific clinical applications. The present review has compared in vitro studies on PEMFs on different osteoblast models, which elucidate potential mechanisms of action for PEMFs, up to the most recent insights into the role of primary cilia, and highlight the critical issues underlying at least some of the inconsistent results in the available literature.

Abstract
The main benefit of xenotransplantation is its potential to overcome the worldwide organ shortage experienced in allotransplantation. Allogeneic transplantation is the only successful therapy for several life-threatening diseases, with cell, tissue or organ donation only partially meeting the demand and many patients dying while waiting for treatment. With supply falling short of demand, it is foreseen that the use of porcine material may at some stage overcome the existing gap between organ availability and clinical need. Recently, pig islet cells have been utilised in clinical trials, with safety being demonstrated. Indeed, pig-derived cells present several advantages: i) porcine cells have a stable function and differentiation pattern and are not tumorigenic; ii) pig cells have been shown to meet the physiological needs in large animal models; iii) the source of pig cells can be scaled up to meet demands in a highly standardised manner, and with respect to animal welfare regulations; iv) 'designated-pathogen-free' (DPF) pig lines can be produced, which could result in a higher safety profile than allotransplantation itself; v) the risk of zoonosis, which was raised years ago as the major hurdle, has been recently circumvented and is actually viewed as a controlled risk; and vi) immune risks are being circumvented via the use of genetically modified donor animals and encapsulation of porcine cells, particularly for the treatment of diabetes. Overall, the benefit appears to outweigh potential risks with respect to cellular xenotransplantation and this is discussed further in this review.

Abstract
Leigh syndrome (LS) associated with cytochrome c oxidase (COX) deficiency is an early onset, fatal mitochondrial encephalopathy, leading to multiple neurological failure and eventually death, usually in the first decade of life. Mutations in SURF1, a nuclear gene encoding a mitochondrial protein involved in COX assembly, are among the most common causes of LS. LSSURF1 patients display severe, isolated COX deficiency in all tissues, including cultured fibroblasts and skeletal muscle. Recombinant, constitutive SURF1-/- mice show diffuse COX deficiency, but fail to recapitulate the severity of the human clinical phenotype. Pigs are an attractive alternative model for human diseases, because of their size, as well as metabolic, physiological and genetic similarity to humans. Here, we determined the complete sequence of the swine SURF1 gene, disrupted it in pig primary fibroblast cell lines using both TALENs and CRISPR/Cas9 genome editing systems, before finally generating SURF1-/- and SURF1-/+ pigs by Somatic Cell Nuclear Transfer (SCNT). SURF1-/- pigs were characterized by failure to thrive, muscle weakness and highly reduced life span with elevated perinatal mortality, compared to heterozygous SURF1-/+ and wild type littermates. Surprisingly, no obvious COX deficiency was detected in SURF1-/- tissues, although histochemical analysis revealed the presence of COX deficiency in jejunum villi and total mRNA sequencing (RNAseq) showed that several COX subunit-encoding genes were significantly down-regulated in SURF1-/- skeletal muscles. In addition, neuropathological findings, indicated a delay in central nervous system development of newborn SURF1-/- piglets. Our results suggest a broader role of sSURF1 in mitochondrial bioenergetics.

Abstract
AIMS AND BACKGROUND Suramin has been shown to be of interest as a potential new anticancer agent because of its capacity to inhibit the binding of several growth factors to their receptors and to inhibit the growth of cancer cells in vitro. Since multi-autocrine loops involving growth factors which are antagonized by suramin have been demonstrated in colorectal cancer, we previously evaluated the activity of suramin in patients with advanced colorectal cancer. Interestingly, in this study three patients who had received 5-FU+LV after suramin, although heavily pretreated with fluoropyrimidines, obtained an objective response. This observation was intriguing as it might have been that suramin had changed the biology of the tumor, making it sensitive to 5-FU+LV. We therefore conducted the present study to investigate the possibility that suramin might overcome the resistance to 5-FU+LV. METHODS AND STUDY DESIGN Only colorectal cancer patients with metastatic and progressive disease during 5-FU+LV-based chemotherapy were eligible for this study. Suramin was administered for eight weeks at doses determined by means of a computer-assisted dosing algorithm that used Bayesian pharmacokinetics to maintain suramin plasma concentrations of 200-250 microg/ml. 5-FU was administered weekly at a dosis of 450 mg/m2 halfway through a two-hour infusion of I-LV 250 mg/m2 starting one week after the initiation of suramin for a maximum of 26 weeks. RESULTS Treatment was relatively well tolerated, but no objective responses were observed after the accrual of 13 patients in the first stage of the trial. Consequently, the trial was interrupted according to the initial two-stage sampling design. CONCLUSIONS The present study does not support the hypothesis that suramin might overcome resistance to 5-FU+LV and its use in colorectal cancer is not recommended.

Abstract
The clinical interest in HER-2/neu is related to trastuzumab, a drug used to treat patients with invasive breast carcinoma overexpressing the HER-2/neu protein. It is very important to correctly identify those patients who may benefit from trastuzumab by accurate assessment of the HER-2/neu status. Of the various methods available, the Dako Herceptest for immunohistochemical assay is considered the most reliable to reach this goal. The aim of this study was to investigate within a group of Italian laboratories the reproducibility of the results of HER-2/neu assessment by means of the Dako scoring system on slides stained with the Herceptest kit. This study was also conceived as the continuation of one of our previous studies, which was similar in its aims but different in the classification criteria adopted. Our results show that, whereas the intra-observer reproducibility was generally satisfactory, the interobserver reproducibility was not. Moreover, our findings confirm that the two extreme classes (0 and 3+) are more easy to identify than the other two and that the Herceptest does not allow to discriminate optimally between scoring classes 2+ and 3+. These findings are relevant in clinical practice where the treatment choice is based on categories defined by this assay, suggesting the need of adopting educational programs and/or new reference materials to improve the assay performance.

Abstract
The transcriptome associated with the ability of oocytes to support embryogenesis and development remains unclear. The aim of this study was to compare the mRNA expression pattern between oocytes collected from fertile heifers (H) and repeat breeders (RB) using RNAseq. Oocytes were collected by ovum pick-up from Italian Simmental (IS) and Holstein Friesian (HF) heifers that became pregnant at the following oestrus, and from cows of the same breeds classified as RB after they failed to become pregnant for a minimum of 3 consecutive AI. Oocytes from each animal (5 for HF_RB, 3 each for all other groups) were pooled and sequenced using Illumina HiSEqn 2000 (Illumina Inc., San Diego, CA, USA). Principal component analysis showed that HF oocytes clustered away from those of IS, irrespective of the fertility status. However, within breeds, H and RB always clustered apart from each other. This suggests that differences in the transcriptional blueprint between breeds was more prominent than differences related to fertility. However, these were still strong when considering breeds separately, therefore we treated breeds as independent groups and performed differential expression analysis on H v. RB in IS and HF. DESEqn 2 identified 135 differentially expressed genes when we compared H and RB in IS and 2124 in HF. This difference in number of DE genes between the 2 breeds reflects the fact that the variance between H and RB transcriptional patterns in HF is larger than in IS. We looked for genes that were differentially and consistently expressed between H and RB in both breeds and identified 10 genes: histone H2B, exo/endonuclease G, solute carrier family 5 member 9, BH3 interacting domain death agonist, TBK1 binding protein 1, purine-rich element binding protein A, tRNA-yW synthesising protein 1 homologue, Jun oncogene, FRA10AC1 homologue, and SKI oncogene. To validate their potential use as biomarkers, we performed a preliminary in vitro validation by RT-qPCR. As described in the literature, oocytes collected from ovaries with more than 10 follicles of 2 to 6 mm were classified as high quality, while those collected from ovaries with fewer than 10 follicles were classified as low quality (Gandolfi et al. 1997 Theriogenology 48, 1153-1160). Gene expression analysis confirmed SLC5A9, a membrane-bound protein involved in sodium-dependent transport of glucose, as a potential biomarker to discriminate between a competent and incompetent oocyte. Altogether, our data provide a detailed overview of the mRNA pattern defining the differences between a competent and incompetent oocyte in vivo, and identified a new potential marker able to differentiate fertile and infertile oocyte both in vivo and in vitro.

Abstract
Embryonic genome activation (EGA) is a complex process that needs a good orchestration of all biochemical processes at the time of maternal-to-embryonic transition. Mitochondria are strictly dependent on the nucleus for their correct activity as ~1500 mitochondrial genes have nuclear localisation. The finding of transcriptional activation and accumulation of mRNAs related to mitochondrial biogenesis (Mtango et al. 2008 Reprod. Fertil. Dev. 20, 846-859) around the time of EGA confirmed the role of nucleus in this process. Studying mitochondria behaviour in interspecies somatic cell nuclear transfer (iSCNT) embryos (Lagutina et al. 2010 Reproduction 140, 273-285), we have found that at the time of EGA, mitochondria activation could be demonstrated by JC-1 accumulation. We suggested that comparison of the mean green fluorescence intensity (FI) that corresponds to the fluorescence of the monomeric form of the dye and correlates to relative mitochondrial mass (Mancini et al. 1997) in iSCNT and control nuclear transfer (NT) could serve as a test to assess EGA in iSCNT embryos. The aim of this study was to estimate nuclear-cytoplasmic interaction in iSCNT embryos that formed nucleoli at the time of EGA (Lagutina et al. 2011 Reproduction 141, 453-465) such as embryos derived from bovine oocytes and bovine (control), buffalo or ovine donor nuclei, and from porcine oocytes and porcine (control), horse, or rabbit nuclei. Embryos 72 h after activation were stained with 2 μM JC-1 in SOF-HEPES with 10% FCS at 37°C for 1 h. Images were collected using a fluorescein isothiocyanate (FITC) filter and analysed with Adobe Photoshop Elements 2 (Adobe Systems, San Jose, CA, USA). The data are presented as mean FI of the embryo. To demonstrate the effect of EGA inhibition on mitochondria, bovine and porcine NT embryos were cultured in medium supplemented with 25 μg/mL α-amanitin (AA) from 48 to 72 h after activation. The analyses of mean FI of the embryos showed that ovine and buffalo nuclei were able to support mitochondrial mass accumulation in iSCNT embryos with bovine oocytes equal to control bovine NT embryos (35 ± 11.2; 41.9 ± 14.8; 36.2 ± 7.6, respectively) that was significantly higher than in bovine embryos treated with AA (15.4 ± 4.9; P < 0.05). In the iSCNT embryos composed of porcine oocytes and equine or rabbit nuclei, mean FI values (20 ± 13.4; 18.3 ± 5.5, respectively) were comparable with those in porcine NT embryos treated with AA (16.2 ± 6.2), and were significantly lower than in porcine control (91 ± 47.7; P < 0.05) NT embryos, demonstrating the inability of equine and rabbit nuclei to properly govern the porcine mitochondria mass growth at the time of EGA. In conclusion, nucleolus formation and activation of nuclear encoded mitochondrial genes at the time of EGA cannot serve, per se, as a marker of correct embryonic genome activation in iSCNT embryos, because, in our conditions, no iSCNT embryos developed to blastocyst (Lagutina et al. 2010 Reproduction 140, 273-285). This knowledge about behaviour of different embryo compartments at the time of EGA could extend our understanding of the whole process.

Abstract
A previous study from our laboratory (Ramos-Ibeas et al. 2017 Mol. Cell. Biochem. 429, 137-150, 10.1007/s11010-017-2942-z) described the protective effect of sodium pyruvate (SP) against H2O2-induced oxidative stress in somatic and embryonic stem cells. In this study, we tested the same experimental conditions on bovine and swine oocytes during in vitro maturation (IVM). To this aim, cumulus-enclosed oocytes (COC) recovered from bovine and swine ovaries were treated for 1 h with different concentrations of H2O2 and then matured in serum-free TCM-199 with and without SP supplementation. All experiments were done in 3 replicates using 12 to 20 oocytes per experimental group; data were analysed by two-way ANOVA. As a first step, we determined the dose-response curve of H2O2 treatment during IVM, using the reaching of metaphase 2 as endpoint. We found that swine COC were more sensitive to H2O2 damage than bovine COC: indeed, they tolerated a range of concentrations from 128 to 512 μM, whereas the range for bovine COC was between 1024 and 4096 μM. The COC from both species were treated for 1 h with 128 μM (swine) or 2048 μM (bovine) H2O2 and then matured with or without different concentrations of SP. Control COC, unexposed to H2O2, were also matured with and without SP supplementation. We found that the addition of 25 mM SP to swine COC reduced the maturation rate both in control and H2O2-treated groups. Instead, reducing the addition of SP to 10 mM we observed a beneficial effect because the metaphase II level in treated oocytes increased from 38% (15/40) to 67% (24/36) and the difference was statistically significant. In bovine COC, the addition of 25 mM SP did not affect control oocytes during IVM but decreased maturation rate in treated oocytes, whereas 10 mM SP had no effect on the control group and showed a tendency to increase maturation rate in treated oocytes. In a second set of experiments, to determine if cumulus cells acted as a barrier for SP to reach the oocyte, the COC were denuded after H2O2 treatment and matured with or without SP. In swine denuded oocytes (DO) matured with SP, the rate of metaphase II increased significantly both in control [from 71% (34/48) to 92% (44/48)] and in treated groups [from 48% (23/48) to 72% (36/50)]. In bovine DO, the supplementation of SP did not increase the maturation rate significantly (25/41 v. 29/41 in control groups, 12/36 v. 18/40 in treated groups). In conclusion, we found that toxic H2O2 concentrations were approximately 10-fold higher for bovine than for swine, indicating that bovine COC were more resistant to oxidative stress. This could explain why SP supplementation had a significant protective effect in swine but only a minor effect in bovine. Moreover, the difference in SP effect between bovine and swine COC could be due to their morphology because bovine cumulus is often larger and more compact than swine cumulus and this difference could influence how SP reaches the inner oocyte and how it is metabolized.

Abstract
The aim of the present study was to investigate how the enrichment of chitosan films with anti-fibronectin aptamers could enhance scaffold colonization by osteoblasts, by improving their adhesion and accelerating their proliferation. Chitosan discs were enriched with excess of anti-fibronectin aptamer. Aptamer adsorption on chitosan was monitored by measuring aptamer concentration in the supernatant by spectrophotometry, as well as its release, while functionalization was confirmed by labelling aptamers with a DNA intercalating dye. Chitosan samples were then characterized morphologically with atomic force microscopy and physically with contact angle measurement. Chitosan enrichment with fibronectin was then investigated by immunofluorescence and Bradford assay. 2% chitosan discs were then enriched with increasing doses of aptamers and used as culture substrates for MC3T3-E1 cells. Cell growth was monitored by optical microscopy, while cell viability and metabolic activity were assessed by chemiluminescence and by Resazurin Sodium Salt assay. Cell morphology was investigated by cytofluorescence and by scanning electron microscopy. Chitosan films efficiently bound and retained aptamers. Aptamers did not affect the amount of adsorbed fibronectin, but affected osteoblasts behavior. Cell growth was proportional to the amount of aptamer used for the functionalization, as well as aptamers influenced cell morphology and their adhesion to the substrate. Our results demonstrate that the enrichment of chitosan films with aptamers could selectively improve osteoblasts behavior. Furthermore, our results support further investigation of this type of functionalization as a suitable modification to ameliorate the biocompatibility of biomaterial for hard tissue engineering applications.

Abstract
Background and aim of the study: Physical performance is the result of a complex combination of several factors such as genetic and anthropometric aspects, nutrition and hormonal status. In the past few years many studies have considered the impact of vitamin D on muscular strength and athletic performance. The aim of the present study was to assess the anthropometric measures impacting on physical performance in a group of professional rugby athletes. As a secondary aim we investigated a possible relationship between baseline vitamin D status and athletic performance status in these subjects. Methods: All rugby players completed a test–retest reliability study on performance measures, as 70kg jump squat and body weight (BW) jump squat to assess musculoskeletal performance. Additionally at the time point we collected a blood sample of every athletes for the assessment of serum vitamin D. Results: We found that lean mass was an important independent predictor of performance score in 70kg jump squat (p=0.007, R2=0.74) and BW jump squat (p=0.010, R2=0.66) in these well trained athletes. No statistically significant association was present between performance score and serum vitamin D in this specific setting. Conclusions: We demonstrate a positive interaction between lower limb lean mass and performance score, but we have not been able to identify any statistically significant association between worsening in performance measures and decrease of serum 25 OH Vitamin D.

Abstract
Androgen hormones play a significant role in regulating bone morphogenesis and in maintaining bone homeostasis throughout life. This study aimed to investigate the local effects of the non-aromatizable androgen stanozolol (ST) on bone regeneration in rats. Bilateral critical-size defects were created in the parietal bone of 26 male Wistar rats: the defect on one side was filled with a deproteinized bovine bone scaffold (DBB) soaked in ST solution (test) and the contralateral with DBB alone (control). Samples were collected at one month and three months. Histomorphometry revealed a significantly higher new bone formation (NB) (24.41% ± 4.14% versus 15.01% ± 2.43%, p < 0.05) and mineral apposition rate (MAR) (9.20 μm/day ± 0.37 versus 6.50 μm/day ± 1.09, p < 0.05) in the test versus control group at one month. Accordingly, real time-polymerase chain reaction revealed a consistently higher Runx2 expression in test samples (fold change test/control: 4.50 ± 1.17, p ≤ 0.05). No morphometrical differences between groups were detected at three months (p > 0.05). However, test samples were characterized by an increase in blood capillary density from one month (11.43 n mm-2 ± 2.01) to three months (28.26 n mm-2 ± 5.62), providing evidence of a vital remodeling tissue. Control samples presented a decrease of anti-Osterix (SP7)/anti-osteocalcin (BGLAP) (3.9 n mm-2 ± 0.32 versus 1.01 n mm-2 ± 0.20) and alkaline phosphatase (ALP) (12.14 n mm-2 ± 6.29 versus 6.29 n mm-2 ± 2.73) immunohistochemical-positive elements, which was suggestive of a stabilized healing phase. Based on these observations, local ST administration boosted bone regeneration in rat calvarial critical-size defects at one month. This study showed the potential of local steroid delivery in bone regeneration.

Abstract
Rough titanium surfaces enhance cell response to activation of Wnt canonical signalling, a pathway required for osteoblast differentiation. The present study investigated the effects of GSK3β-inhibitors SB216763 and SB415286 on osteoblastic differentiation on titanium surfaces with different topography and wettability. Osteoblastic MC3T3 cells were plated on smooth (Pickled), sand-blasted/acid-etched (SLA) or hyper hydrophilic SLA (modSLA) titanium discs and transfected with a reporter vector sys-tem for Wnt canonical signalling. Cells were also seeded in the presence or in the absence of GSK3b-inhibitors SB216763 or SB415286 and their viability, morphology and the expression of Wnt target and osteoblast specific genes was assessed by Real Time PCR. Inhibitors altered cell morphology and mostly reduced cell viability at high concentration. SB415286 markedly increased the expression of ALP in MC3T3 cells on rough surfaces at the concentration of 100 nM before decreasing its expression at higher concentrations. OCN expression was unaffected. Increasing concentrations of SB216763 increased the expression of ALP in MC3T3 cells on rough surfaces but OCN expression was not changed at any con-centration. SB216763 and SB415286 inhibitors should be further investigated as potential tools to improve cell differentiation on titanium surfaces for endosseous implants.

Abstract
The receptor for advanced glycation end products (RAGE) is a member of the immunoglobulin superfamily that binds a broad repertoire of advanced glycation end products ligands. It is constitutively expressed at a high level during embryonic development, but its levels decrease in adult tissues. The RAGE-ligand interaction induces a series of signal transduction cascades and leads to the activation of several inflammatory signalling pathways. This is why RAGE is frequently associated with pro-inflammatory responses and it is implicated as an underlying condition in immune disorders, cardiovascular diseases, diabetes, Alzheimer’s disease, and cancer. However, the physiological function of RAGE during embryogenesis and in aging is largely undefined. The aim of this work was to determine the basal levels on RAGE expression in bovine oocytes (germinal vesicle, GV, and in vitro-matured metaphase II) and in vitro-derived embryos developed in SOF medium, by qPCR (3 replicates each containing pooled RNA from 20 oocytes or embryos, t-test P < 0.05) and immunostaining. The expression of RAGE was similar in bovine oocytes, in cleaving embryos up to morula, and afterward declined at the blastocyst stage. However, a more detailed investigation, by the separation of the inner cell mass (ICM) from the trophoblast, indicated that expression decreased only in the trophoblast (over 5-fold) while it was maintained high in the isolated ICM. In the trophoblast, compared to the ICM, this finding coincided with an elevated expression of PSMA6 gene, which encodes for the 20S proteasome subunit, and ubiquitin (UBB) gene, suggesting a link between proteasome activity and RAGE expression. Then we investigated the expression of RAGE and the proteasome-ubiquitin system in embryos cultured under different oxygen concentrations [i.e. physiological (5%) or high (20%) O2 levels]. Preliminary results showed that RAGE expression was lower in embryos cultured in 20% O2 and conversely the expression of PSMA6 and UBB genes was higher. Thus, these results indicate that the activity of RAGE-mediated stress response pathway in pre-implantation bovine embryos is affected by O2 tension during in vitro culture.

Abstract
Programmable nucleases (ZFN, Tal Effector Nucleases, and CRISPR) opened a new era for mammal genome editing, in particular for the pigs used for xenotransplantation. Multiple gene editing events are required both for knockout (KO) of xenoantigens and for targeted integration of human protective genes (Perota et al. 2016 J. Genet. Genomics 43, 233–23). The objective of the present work was to edit selected pig lines to KO the enzymes coding for the most relevant xenoantigens (i.e. GGTA1, CMAH, and B4GalNT2), combining Talens and CRISPR/Cas9 technologies to magnetic beads selection (Li et al. 2013 Xenotransplantation 22, 20–31). Primary porcine adult fibroblasts were transfected using Nucleofector (V-024 program). In a single reaction 2 × 106 fibroblasts were co-transfected using 2 different sets of TALENS (4 μg/set) specific for CMAH (Conchon et al., 2013) and GGTA1 (Perota et al., 2015) genes together with B4GalNT2-specific CRISPR/Cas9 expression vector (2 μg; pX330-B4GalNT2; Estrada et al., 2015). Eight days post-transfection (DPT), Gal–/– cells were selected initially using biotin-conjugated IB4 lectin (Sigma, St. Louis, MO, USA) and magnetic beads (Dynabeads M-280, Thermo Fisher Scientific, Waltham, MA, USA). The selected cells were then plated on 150-mm Petri dishes (200 cells/dish) and cultured for 10 days. Selected colonies were expanded for PCR analysis and cryopreserved for somatic cell nuclear transfer (SCNT). All colonies were analysed by PCR for CMAH gene and their resulting products were digested with HindIII (HindIII-RFLP). Colonies that lost wild-type HindIII as a consequence of Talens effected deletion were PCR characterised for GGTA1, selecting those that had detectable Indels after gel electrophoresis and finally analysed by PCR for B4GalNT2. All PCR products were validated by sequencing for all the 3 genes of interest (TopoTA, Thermo Fisher Scientific). Selected colonies were used as nuclear donors for SCNT (Lagutina et al., 2006). Eight DPT we obtained 3.45 ×106 cells. About 6.0 × 103 Gal-negative cells (0.17%) were collected from the supernatant after magnetic beads separation. Eighteen DPT, 120 colonies were picked up and their HindIII-RFLP analyses on CMAH gene revealed that 22 colonies (18.3%) were KO for both CMAH alleles. Of these 22 colonies following electrophoretic analyses of GGTA1-PCR products, 13 colonies had detectable Indels. These 13 colonies were finally PCR analysed and sequenced for B4GalNT2 and sequenced. Final sequencing results confirmed that 2 colonies (1.6%) resulted in KO for the 3 genes. Three different zona-free SCNT experiments were done and 579 reconstructed embryos were obtained. On Day 7, 322 morulae or blastocysts (56%) were transferred in 3 synchronised sows and 2 (66%) became pregnant. In conclusion, after gene editing with programmable nucleases, combining beads-mediated selection with well-designed molecular analyses, we developed a multistep assay that can be used efficiently to detect desired gene edited events in cell colonies suitable for the SCNT. Embryos generated after SCNT were able to establish pregnancies at a high rate.

Abstract
We report on the synthesis and characterization of a composite nanostructure based on the coupling of cerium fluoride (CeF3) and zinc oxide (ZnO) for applications in self-lighted photodynamic therapy. Self-lighted photodynamic therapy is a novel approach for the treatment of deep cancers by low doses of X-rays. CeF3 is an efficient scintillator: when illuminated by X-rays it emits UV light by fluorescence at 325 nm. In this work, we simulate this effect by exciting directly CeF3 fluorescence by UV radiation. ZnO is photo-activated in cascade, to produce reactive oxygen species. This effect was recently demonstrated in a physical mixture of distinct nanoparticles of CeF3 and ZnO [Radiat. Meas. (2013) 59:139-143]. Oxide surface provides a platform for rational functionalization, e.g., by targeting molecules for specific tumors. Our composite nanostructure is stable in aqueous media with excellent optical coupling between the two components; we characterize its uptake and its good cell viability, with very low intrinsic cytotoxicity in dark.

Abstract
BACKGROUND/OBJECTIVES Blood polyunsaturated fatty acids (PUFA) are involved in allergy development, but the etiological role of n-6 and n-3 PUFA is still controversial. A European multicenter study of children (IDEFICS) provided the opportunity to explore the cross-sectional association between fatty acids (FA) and allergy. SUBJECTS/METHODS Blood FA levels were measured in 2600 children aged 2-9 years and were recorded as the percentage of weight of all FA detected. Logistic regression of allergy status on FA components was adjusted for age, sex, country, body mass index, family history of allergic disease, breast-feeding, and number of siblings. The results were given as odds ratios (OR) for current vs no allergy ever and an increase in FA by 1 s.d. RESULTS Overall, higher proportions of n-6 PUFA were associated with higher odds of allergy (OR=1.21 (1.05, 1.40)). Monounsaturated FA (MUFA) were associated with reduced risk for allergy (OR=0.75 (0.65, 0.87)), whereas saturated FA did not differ by allergy status. The strongest associations were observed in children <4 years old, with ORs of allergy given as 1.62 (1.15, 2.29) for n-3 PUFA and 0.63 (0.42, 0.95) for MUFA. With regard to individual FA, these associations were independently observed for docosapentaenoic acid (22:5 n-3) and oleic acid (18:1 n-9). CONCLUSIONS Both PUFA subtypes were positively associated with allergy in an age-dependent manner, whereas MUFA was associated with less allergy. The observation of high proportions of n-3 PUFA in allergic children younger than 4 years might help to understand the nature of early onset of atopic disease.
