Abstract
A retrospective study was carried out to investigate incidence, clinical signs and ultrasonographic findings of ovarian tumours in a population of dogs referred to the Veterinary Teaching Hospital of the University of Perugia (Italy) and Anicura Tyrus Veterinary Clinic (Terni, Italy). The period of study ranged from January 2005 to December 2021. A total of 1910 dogs were affected by neoplasia but only 35 of them (1.8%), of different breeds and ages, were found to have ovarian tumours. Ultrasound of the ovaries was performed based on clinical signs; the diagnosis was achieved after ultrasound findings prompted ovariohysterectomy and ovarian pathologic evaluation In our study, the age of bitches affected by ovarian neoplasia ranged from 3 to 20 years (mean 9.6 ± 3.8). The histopathological findings of ovarian masses identified 16 granulosa cell tumours (GCT) (46%), 7 adenomas (20%), 5 adenocarcinomas (14%), 2 teratomas (6%), 1 leiomyoma (3%), 1 luteoma (3%), 1 tecoma (3%), 1 dysgerminoma (3%), and 1 haemangiosarcoma (3%). In particular, with respect to clinical signs, 69% of bitches showed abnormalities of estrus cycle (short interestral interval, persistent estrus, prolonged interestral interval). The other main clinical signs included abdominal distention, palpable abdominal mass, vulvovaginal discharge, polyuria/polydipsia, mammary masses. When present, the laboratory abnormalities were slight anemia and leucocytosis with neutrophilia. The tumours were ultrasonographically classified as mainly solid: 12/35 (34%) (1 adenoma, 4 adenocarcinomas, 1 dysgerminoma, 1 haemangiosarcoma, 1 leyomioma, 1 luteoma, 1 GCT, 1 tecoma, 1 teratoma); solid with cystic component 13/35 (37%) (9 GCT, 2 Adenomas, 1 adenocarcinoma, 1 teratoma); and mainly cystic 10/35 (29%) (6 GCTs, 4 adenomas). In our study, the ultrasound examination allowed us to suspect ovarian neoplasia in asymptomatic subjects referred for breeding management or for preventive health check. On the basis of our data, we proposed to perform a complete periodic examination of the reproductive system once a year from 6 years. Nevertheless, the presence of ovarian neoplasms found in young subjects, during breeding management, suggest including routine ultrasound examination of the reproductive tract.

Abstract
Extracellular vesicles (EVs) are small spherical particles surrounded by a membrane with an unusual lipid composition and a striking cholesterol/phospholipidic ratio. About 2000 lipid and 3500 protein species were identified in EVs secreted by different cell sources. EVs mediate cell to cell communication in proximity to or distant from the cell of origin. In particular, it was suggested that they represent modulators of multiple processes during pregnancy. The aim of this study was to identify the presence of EVs in canine amnion-derived cells (ASCs) culture and the expression of CD 59 on their surface. Amniotic membrane was collected in PBS with antibiotics added from 2 bitches during elective caesarean section. Cells culture was prepared and EVs were isolated. EVs were used to evaluate CD59 expression by flow cytofluorimetry. We found that the majority of EVs expressed CD59. Our results could increase the knowledge about the complex mechanisms that regulate the pregnancy in the bitch.

Abstract
Chronic rhinosinusitis (CRS) is known to affect around 5 % of the total population, with major impact on the quality of life of those severely affected (1). Despite a substantial burden on individuals, society and health economies, CRS often remains underdiagnosed, under-estimated and under-treated (2). International guidelines like the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) (3) and the International Consensus statement on Allergy and Rhinology: Rhinosinusitis 2021 (ICAR) (4) offer physicians insight into the recommended treatment options for CRS, with an overview of effective strategies and guidance of diagnosis and care throughout the disease journey of CRS.

Abstract
Spinal anesthesia is a common procedure performed in orthopedic surgery, and it is regarded as secure and safe. Although puncture-related complication of spinal anesthesia has a very low incidence, it would lead to dramatic neurological damage (tetra- or paraplegia). Early diagnosis and surgical decompression are mandatory to promote a better outcome. We present a case of acute spinal hematoma from T11 to L3, triggered by laborious anesthesia puncture after total knee arthroplasty. A prompt surgical decompression within few hours after diagnosis allowed rapid functional recovery and avoided permanent paraplegia.

Abstract
BACKGROUND A recent analysis suggested potential narrowing of the gender gap in research productivity in the field of rhinology. This analysis did not, however, provide insight into how the genders are represented in the rhinologic literature. This study aimed to evaluate 11 years of literature to evaluate for gender differences in authorship position, collaborations, category and content of research, citations, and funding to gain perspective on how gender and authorship has changed over time. METHODS Authorship data for all articles on rhinologic subject matter published between January 1, 2008 and December 31, 2018 in four otolaryngology journals was collected. The gender of authors was determined by protocol. Category and content of research and funding status/source were additionally obtained. RESULTS Data were collected from 2666 articles. Gender of 14,510 authors was determined. Female authors accounted for 23% of the overall authors and male authors accounted for 77%. Female first authorship increased significantly over time, but there was no change in female senior authorship. The percentage of female authors steadily increased over time, whereas male authorship decreased slightly. Mixed gender teams were shown to be increasing in frequency. Women published more than expected in basic science and allergy and less than expected in skull base. On funded studies, women were significantly underrepresented as senior authors. CONCLUSION This study represents the first assessment of gender differences in the rhinology literature. Areas where female representation can improve include senior authorship, increased involvement in skull base publications, and increased funding.

Abstract
Twenty-one two-proton knockout (p,3p) cross sections were measured from neutron-rich nuclei at ∼250 MeV/nucleon in inverse kinematics. The angular distribution of the three emitted protons was determined for the first time, demonstrating that the (p,3p) kinematics are consistent with two sequential proton-proton collisions within the projectile nucleus. Ratios of (p,3p) over (p,2p) inclusive cross sections follow the trend of other many-nucleon removal reactions, further reinforcing the sequential nature of (p,3p) in neutron-rich nuclei.

Abstract
Endoscopic and open microsurgical approaches for pediatric patients are useful for a wide variety of skull base pathologies. A hybrid, cranioendoscopic approach may be beneficial in improving surgical resection for complex lesions. A case of a 13-year-old boy with a large juvenile nasopharyngeal angiofibroma extending through the nasopharynx and pterygopalatine fossa into the maxillary, sphenoid, and cavernous sinuses is demonstrated via an endoscopic, transnasal and frontotemporal, extended middle cranial fossa microsurgical approach. Management of a large pediatric tumor via narrow nasal passages, safe surgical resection around critical neurovascular structures, and complication avoidance is demonstrated. The video can be found here: https://youtu.be/1WqvsOnQCxs.

Abstract
The European Position Paper on Rhinosinusitis and Nasal Polyps 2020 is the update of similar evidence based position papers published in 2005 and 2007 and 2012. The core objective of the EPOS2020 guideline is to provide revised, up-to-date and clear evidence-based recommendations and integrated care pathways in ARS and CRS. EPOS2020 provides an update on the literature published and studies undertaken in the eight years since the EPOS2012 position paper was published and addresses areas not extensively covered in EPOS2012 such as paediatric CRS and sinus surgery. EPOS2020 also involves new stakeholders, including pharmacists and patients, and addresses new target users who have become more involved in the management and treatment of rhinosinusitis since the publication of the last EPOS document, including pharmacists, nurses, specialised care givers and indeed patients themselves, who employ increasing self-management of their condition using over the counter treatments. The document provides suggestions for future research in this area and offers updated guidance for definitions and outcome measurements in research in different settings. EPOS2020 contains chapters on definitions and classification where we have defined a large number of terms and indicated preferred terms. A new classification of CRS into primary and secondary CRS and further division into localized and diffuse disease, based on anatomic distribution is proposed. There are extensive chapters on epidemiology and predisposing factors, inflammatory mechanisms, (differential) diagnosis of facial pain, allergic rhinitis, genetics, cystic fibrosis, aspirin exacerbated respiratory disease, immunodeficiencies, allergic fungal rhinosinusitis and the relationship between upper and lower airways. The chapters on paediatric acute and chronic rhinosinusitis are totally rewritten. All available evidence for the management of acute rhinosinusitis and chronic rhinosinusitis with or without nasal polyps in adults and children is systematically reviewed and integrated care pathways based on the evidence are proposed. Despite considerable increases in the amount of quality publications in recent years, a large number of practical clinical questions remain. It was agreed that the best way to address these was to conduct a Delphi exercise . The results have been integrated into the respective sections. Last but not least, advice for patients and pharmacists and a new list of research needs are included. The full document can be downloaded for free on the website of this journal: http://www.rhinologyjournal.com.

Abstract
Apelin is a potent inotropic agent causing endothelium-mediated vasodilation and is involved in vessel formation by interacting with a specific receptor. Its cardiovascular profile suggests a role in the regulation of gestational hemodynamic changes. The expression of apelin and its receptor has been reported in some portions of the reproductive tract of different mammalian species. As far as we know, there are no reports describing the expression of apelin and apelin receptor in bitch's placenta. Therefore, the aim of this study was to investigate, for the first time, the presence and distribution of apelin and apelin receptor in bitch placenta by molecular biology and immunohistochemical techniques. Sixteen adult female half-breed bitches were used. The animals were divided into two groups based on the stage of pregnancy: group 1 (mid-gestation n = 8) and group 2 (end gestation n = 8). These bitches were subjected to ovariohysterectomy (group1) or non-conservative caesarean section (group 2). The immunohistochemical technique revealed the presence of positive immune reaction for apelin and apelin receptor in all the samples examined at 30 days and at the end of pregnancy. In particular, apelin and apelin receptor staining was evident in the cytoplasms of cytotrophoblasts and in epithelial cells of the maternal portion. Even if not included into the structure of the placenta, the uterine glands also exhibited a positive immune reaction for apelin and apelin receptor. The RT-PCR analysis showed the presence of transcripts for apelin and apelin receptor in all the placenta samples examined. On the basis of our results it was also possible to hypothesize a potential role of apelin in the control of local placenta blood flow during pregnancy development in bitches.

Abstract
The β-delayed γ-ray spectroscopy of neutron-rich ^{123,125}Ag isotopes is investigated at the Radioactive Isotope Beam Factory of RIKEN, and the long-predicted 1/2^{-} β-emitting isomers in ^{123,125}Ag are identified for the first time. With the new experimental results, the systematic trend of energy spacing between the lowest 9/2^{+} and 1/2^{-} levels is extended in Ag isotopes up to N=78, providing a clear signal for the reduction of the Z=40 subshell gap in Ag towards N=82. Shell-model calculations with the state-of-the-art V_{MU} plus M3Y spin-orbit interaction give a satisfactory description of the low-lying states in ^{123,125}Ag. The tensor force is found to play a crucial role in the evolution of the size of the Z=40 subshell gap. The observed inversion of the single-particle levels around ^{123}Ag can be well interpreted in terms of the monopole shift of the π1g_{9/2} orbitals mainly caused by the increasing occupation of ν1h_{11/2} orbitals.

Fifty-five inclusive single nucleon-removal cross sections from medium mass neutron-rich nuclei impinging on a hydrogen target at ∼250 MeV/nucleon are measured at the RIKEN Radioactive Isotope Beam Factory. Systematically higher cross sections are found for proton removal from nuclei with an even number of protons as compared to odd-proton number projectiles for a given neutron separation energy. Neutron removal cross sections display no even-odd splitting, contrary to nuclear cascade model predictions. Both effects are understood through simple considerations of neutron separation energies and bound state level densities originating in pairing correlations in the daughter nuclei. These conclusions are supported by comparison with semimicroscopic model predictions, highlighting the enhanced role of low-lying level densities in nucleon-removal cross sections from loosely bound nuclei.

Abstract
We have previously reported on the isolation and chromosomal mapping of a novel human gene (SEL1L), which shows sequence similarity to sel-1, an extragenic suppressor of C. elegans. sel-1 functions as a negative regulator of lin-12 activity, the latter being implicated in the control of diverse cellular differentiation events. In the present study we compare the expression patterns of SEL1L and TAN-1, the human ortholog of lin-12 in normal and neoplastic cells. We found that, whereas both genes are expressed in fetal tissues at similar levels, they are differentially expressed in normal adult and neoplastic cells. In normal adult cells SEL1L is generally present at very low levels; only in the cells of the pancreas does it show maximum expression. By contrast, SEL1L is generally well represented in most neoplastic cells but not in those of pancreatic and gastric carcinomas, where transcription is either downregulated or completely repressed. TAN-1 on the other hand is well represented in almost all normal and neoplastic cells, with very few exceptions. Our observations suggest that SEL1L is presumably implicated in pancreatic and gastric carcinogenesis and that, along with TAN-1, it is very important for normal cell function. Alterations in the expression of SEL1L may be used as a prognostic marker for gastric and pancreatic cancers.

Abstract
SEL1L, highly similar to the C. elegans sel-1 gene, is a recently cloned human gene whose function is under investigation. SEL1L is differentially expressed in tumors and normal tissues and seems to play a role in tumor growth and aggressiveness. We used the recombinant N-terminus of the SEL1L protein to immunize a Balb/c mouse and produce a monoclonal antibody. A hybridoma secreting an antibody specifically reacting on the SEL1L recombinant fragment was selected. This monoclonal antibody, named MSel1, recognizes the SEL1L protein by Western blotting, immunofluorescence and immunohistochemistry on normal and tumor cells. MSel1 is able to recognize SEL1L even on archival tumor specimens and is therefore particularly appropriate to study SEL1L involvement in tumor progression.

Abstract
Excited states in mirror nuclei 31S and 31P were populated in the 1n and 1p exit channels, respectively, of the reaction 20Ne + 12C. The beam of 20Ne, with an energy of 33 MeV, was delivered for the first time by the Piave-Alpi accelerator of the Laboratori Nazionali di Legnaro. Angular correlations of coincident pairs and Doppler-shift attenuation lifetime measurements in 31S and 31P were performed using the multidetector array GASP in conjunction with the EUCLIDES charged particle detector. A comparison of the determined B(E1) strengths of the analog mirror 7/2- → 5/2+ transitions indicates the presence of a violation of isospin symmetry.

Abstract
Fission-fragment mass distributions were measured for ^{237-240}U, ^{239-242}Np, and ^{241-244}Pu populated in the excitation-energy range from 10 to 60 MeV by multinucleon transfer channels in the reaction ^{18}O+^{238}U at the Japan Atomic Energy Agency tandem facility. Among them, the data for ^{240}U and ^{240,241,242}Np were observed for the first time. It was found that the mass distributions for all the studied nuclides maintain a double-humped shape up to the highest measured energy in contrast to expectations of predominantly symmetric fission due to the washing out of nuclear shell effects. From a comparison with the dynamical calculation based on the fluctuation-dissipation model, this behavior of the mass distributions was unambiguously attributed to the effect of multichance fission.

Abstract
We describe the case of a woman who came to our attention for acute onset and very rapidly worsening left hemiplegia, vision loss and cognitive impairment. MRI, laboratory and clinical investigations were highly suggestive of an active inflammatory demyelinating disease. Following exclusion of other possible etiologies, a diagnosis of Marburg's variant multiple sclerosis was made. After repeated high-dose steroids and plasma-exchange, the patient was treated with a first course of alemtuzumab followed by improvement of the clinical and MRI picture. This is the first reported case of Marburg type multiple sclerosis treated with alemtuzumab.

Abstract
We report on the first γ-ray spectroscopy of low-lying states in neutron-rich ^{98,100}Kr isotopes obtained from ^{99,101}Rb(p,2p) reactions at ∼220 MeV/nucleon. A reduction of the 2_{1}^{+} state energies beyond N=60 demonstrates a significant increase of deformation, shifted in neutron number compared to the sharper transition observed in strontium and zirconium isotopes. State-of-the-art beyond-mean-field calculations using the Gogny D1S interaction predict level energies in good agreement with experimental results. The identification of a low-lying (0_{2}^{+}, 2_{2}^{+}) state in ^{98}Kr provides the first experimental evidence of a competing configuration at low energy in neutron-rich krypton isotopes consistent with the oblate-prolate shape coexistence picture suggested by theory.

Abstract
Excited states in the nucleus ^{133}Sn, with one neutron outside the double magic ^{132}Sn core, were populated following one-neutron knockout from a ^{134}Sn beam on a carbon target at relativistic energies at the Radioactive Isotope Beam Factory at RIKEN. Besides the γ rays emitted in the decay of the known neutron single-particle states in ^{133}Sn additional γ strength in the energy range 3.5-5.5 MeV was observed for the first time. Since the neutron-separation energy of ^{133}Sn is low, S_{n}=2.402(4) MeV, this observation provides direct evidence for the radiative decay of neutron-unbound states in this nucleus. The ability of electromagnetic decay to compete successfully with neutron emission at energies as high as 3 MeV above threshold is attributed to a mismatch between the wave functions of the initial and final states in the latter case. These findings suggest that in the region southeast of ^{132}Sn nuclear structure effects may play a significant role in the neutron versus γ competition in the decay of unbound states. As a consequence, the common neglect of such effects in the evaluation of the neutron-emission probabilities in calculations of global β-decay properties for astrophysical simulations may have to be reconsidered.

Abstract
The Cochrane Corner is a section in the journal that highlights systematic reviews relevant to otolaryngology-head and neck surgery, with invited commentary to aid clinical decision making. This installment features a pair of related Cochrane Reviews on intranasal steroids for chronic rhinosinusitis, which identify low- to moderate-quality evidence for a beneficial effect on overall symptoms, nasal congestion, and rhinorrhea. There is no evidence, however, to suggest superiority of any particular steroid preparation or drug delivery system. The related expert commentary should help clinicians make the best treatment decisions based on the studies and outcomes identified in these Cochrane Reviews.

Abstract
The first measurement of the low-lying states of the neutron-rich ^{110}Zr and ^{112}Mo was performed via in-beam γ-ray spectroscopy after one proton removal on hydrogen at ∼200 MeV/nucleon. The 2_{1}^{+} excitation energies were found at 185(11) keV in ^{110}Zr, and 235(7) keV in ^{112}Mo, while the R_{42}=E(4_{1}^{+})/E(2_{1}^{+}) ratios are 3.1(2), close to the rigid rotor value, and 2.7(1), respectively. These results are compared to modern energy density functional based configuration mixing models using Gogny and Skyrme effective interactions. We conclude that first levels of ^{110}Zr exhibit a rotational behavior, in agreement with previous observations of lighter zirconium isotopes as well as with the most advanced Monte Carlo shell model predictions. The data, therefore, do not support a harmonic oscillator shell stabilization scenario at Z=40 and N=70. The present data also invalidate predictions for a tetrahedral ground state symmetry in ^{110}Zr.

Abstract
Prostasome-like vesicles (PV) are components of the canine prostatic fluid during ejaculation and despite some enzymatic activities have been identified recently, their functions in the reproductive events in this species are still poorly understood. In this study, we evaluated at neutral or slightly alkaline pH, the effects of different concentrations of purified PV on sperm cell motility characteristics and the impact on the short- and long-term preservation of preserved semen maintained at room temperature. Two different experiments were performed. In the first experiment, purified PV were added at increasing concentration (1.25, 2.5, 5, 10, and 20 μL equivalent to 1, 2, 4, 8, and 16 μg of protein, respectively) to aliquots of 100 μL of preserved semen maintained at 22 °C at the following time points: 0, 30, 60, 120, 240, and 480 min. Computer-assisted sperm motility characteristics and pH were assessed three times at each time points, for each sample and for every concentrations. In the second experiment, the purified PV were added with the same methods as described above but only at time 0. Sperm motility characteristics and pH were assessed over the time. This study showed how the addition of purified PV to preserved semen affects negatively (p < 0.05) at neutral and alkaline pH, both total and progressive motility in a concentration depending manner. Furthermore, prostasome addition was demonstrated to change the quality of sperm movement which may represent a mechanism facilitating sperm cells attachment to the uterine epithelium and facilitating energy preservation before fertilization.

Abstract
The β-decay half-lives of 110 neutron-rich isotopes of the elements from _{37}Rb to _{50}Sn were measured at the Radioactive Isotope Beam Factory. The 40 new half-lives follow robust systematics and highlight the persistence of shell effects. The new data have direct implications for r-process calculations and reinforce the notion that the second (A≈130) and the rare-earth-element (A≈160) abundance peaks may result from the freeze-out of an (n,γ)⇄(γ,n) equilibrium. In such an equilibrium, the new half-lives are important factors determining the abundance of rare-earth elements, and allow for a more reliable discussion of the r process universality. It is anticipated that universality may not extend to the elements Sn, Sb, I, and Cs, making the detection of these elements in metal-poor stars of the utmost importance to determine the exact conditions of individual r-process events.

Abstract
Delayed γ-ray cascades, originating from the decay of (6⁺) isomeric states, in the very neutron-rich, semimagic isotopes (136,138)Sn have been observed following the projectile fission of a ²³⁸U beam at RIBF, RIKEN. The wave functions of these isomeric states are proposed to be predominantly a fully aligned pair of f(7/2) neutrons. Shell-model calculations, performed using a realistic effective interaction, reproduce well the energies of the excited states of these nuclei and the measured transition rates, with the exception of the B(E2;6⁺→4⁺) rate of ¹³⁶Sn, which deviates from a simple seniority scheme. Empirically reducing the νf(7/2)(2) orbit matrix elements produces a 4₁⁺ state with almost equal seniority 2 and 4 components, correctly reproducing the experimental B(E2;6⁺→4⁺) rate of ¹³⁶Sn. These data provide a key benchmark for shell-model interactions far from stability.

Abstract
Search for a new kind of superfluidity built on collective proton-neutron pairs with aligned spin is performed studying the Gamow-Teller decay of the T=1, J(π)=0+ ground state of (62)Ge into excited states of the odd-odd N=Z nucleus (62)Ga. The experiment is performed at GSI Helmholtzzentrum für Shwerionenforshung with the (62)Ge ions selected by the fragment separator and implanted in a stack of Si-strip detectors, surrounded by the RISING Ge array. A half-life of T1/2=82.9(14) ms is measured for the (62)Ge ground state. Six excited states of (62)Ga, populated below 2.5 MeV through Gamow-Teller transitions, are identified. Individual Gamow-Teller transition strengths agree well with theoretical predictions of the interacting shell model and the quasiparticle random phase approximation. The absence of any sizable low-lying Gamow-Teller strength in the reported beta-decay experiment supports the hypothesis of a negligible role of coherent T=0 proton-neutron correlations in (62)Ga.

Abstract
A new isomer with a half-life of 23.0(8) ms has been identified at 2406 keV in (126)Pd and is proposed to have a spin and parity of 10(+) with a maximally aligned configuration comprising two neutron holes in the 1h(11/2) orbit. In addition to an internal-decay branch through a hindered electric octupole transition, β decay from the long-lived isomer was observed to populate excited states at high spins in (126)Ag. The smaller energy difference between the 10(+) and 7(-) isomers in (126)Pd than in the heavier N=80 isotones can be interpreted as being ascribed to the monopole shift of the 1h(11/2) neutron orbit. The effects of the monopole interaction on the evolution of single-neutron energies below (132)Sn are discussed in terms of the central and tensor forces.

Abstract
Coulomb-excitation experiments to study electromagnetic properties of radioactive even-even Hg isotopes were performed with 2.85 MeV/nucleon mercury beams from REX-ISOLDE. Magnitudes and relative signs of the reduced E2 matrix elements that couple the ground state and low-lying excited states in Hg182-188 were extracted. Information on the deformation of the ground and the first excited 0+ states was deduced using the quadrupole sum rules approach. Results show that the ground state is slightly deformed and of oblate nature, while a larger deformation for the excited 0+ state was noted in Hg182,184. The results are compared to beyond mean field and interacting-boson based models and interpreted within a two-state mixing model. Partial agreement with the model calculations was obtained. The presence of two different structures in the light even-mass mercury isotopes that coexist at low excitation energy is firmly established.

Abstract
A low-lying state in 131In82, the one-proton hole nucleus with respect to double magic 132Sn, was observed by its γ decay to the Iπ=1/2- β-emitting isomer. We identify the new state at an excitation energy of Ex=1353 keV, which was populated both in the β decay of 131Cd83 and after β-delayed neutron emission from 132Cd84, as the previously unknown πp3/2 single-hole state with respect to the 132Sn core. Exploiting this crucial new experimental information, shell-model calculations were performed to study the structure of experimentally inaccessible N=82 isotones below 132Sn. The results evidence a surprising absence of proton subshell closures along the chain of N=82 isotones. The consequences of this finding for the evolution of the N=82 shell gap along the r-process path are discussed.

Abstract
Abstract
miR-9 has been described as an oncogenic microRNA associated to a metastatic phenotype and able to induce EMT (epithelial-to-mesenchymal transition) through direct targeting of E-cadherin. However, data available concerning the expression and the role of this microRNA in different subgroups of breast cancer are still not exhaustive.
Evaluating miR-9 expression by Real-Time PCR in a series of 92 breast cancer specimens (35 luminal, 36 HER2, 21 triple negative), we found that this microRNA is increasingly higher in HER2 and Triple Negative versus ER positive patients (fold change 3 and 8 respectively).
Moreover, preliminary analysis of miR-9 expression in correlation with bio-pathological features and clinical data also indicates a trend in association with disease progression.
Triple Negative Breast Cancers represent a very aggressive breast cancer subgroup, still lacking specific markers for an effective targeted therapy; we investigated whether miR-9 might play a role in the biology of this tumor subtype. Preliminary data indicate that miR-9 is activated downstream PDGFRbeta, which represents a crucial player in the aggressive phenotype of Triple Negative Breast Cancer.
In summary, here we show that miR-9 is significantly upregulated in triple negative breast cancer in comparison with other breast cancer subgroups and is activated downstream PDGFRbeta.

Abstract
Abstract
The incidence of breast cancer among Chinese women has been historically much lower than that of Caucasian women but has increased dramatically over the past 30 years in urban areas of China, an increase likely to continue in the next decades across China with progressive urbanization and economic development. However, it is still unclear whether differences in breast cancer incidence between Chinese and Caucasian women reflect differences in disease biology in addition to environmental factors. To address this question, we compared consecutive cohorts of Chinese and Italian breast cancer patients who underwent surgical resection in the years 2005-2007 at Fudan Cancer Center of Shanghai (China) and Fondazione IRCCS Istituto Tumori of Milan (Italy), respectively, two comprehensive cancer centers with similar inpatients and outpatients recruited in a large area. Analyses of clinico-pathological characteristics of 1563 Chinese and 1052 Italian consecutive breast cancer patients revealed that 50% of patients in the Chinese cohort were younger than 50 years versus 29% of Italian patients, indicating that Chinese women develop breast cancer earlier than Italian patients, with a peak of frequency at 50-60 years. Among Chinese breast tumors, 63% were estrogen receptor (ER)-positive versus 85% of the Italians, and the prevalence of ER-positive tumors was equivalent in pre- and postmenopausal Chinese cases, suggesting the same hormonal features in tumors of younger and older patients, consistent with findings in the Italian cohort.
Microarray-based gene and miRNA expression profiling was then conducted on 80 Chinese and 97 Italian samples using Illumina Gene and MicroRNA expression technologies. To minimize potential bias and artifact due to variability in specimen collection, storage, processing and analysis of high-throughput results, samples initially collected in the Chinese and Italian hospitals were all stored, randomly processed and analyzed in the Italian center. Analysis revealed a comparable pattern of gene and miRNA expression in the 2 cohorts with unsupervised hierarchical clustering of 12,338 genes and 858 miRNAs, and similar expression of intrinsic and extracellular matrix (ECM) genes led to a similar partition in intrinsic and ECM subtypes, indicating molecular similarity among Chinese and Caucasian breast cancers.

Abstract
BACKGROUND Currently used CA15-3 and CEA have found their clinical application particularly in the follow-up of patients with advanced disease. Novel biomarkers are urgent, especially for improving early diagnosis as well as for discriminating between benign and malignant disease. PATIENTS AND METHODS In the present study, we used a proteomic approach based on surface-enhanced laser desorption/ionization-time of flight-mass spectrometry screening with the aim of identifying differentially expressed 2-30 kDa proteins in plasma of patients with malignant (65 cases) and benign (88 cases) breast lesions with respect to 121 healthy controls. RESULTS We found that the most promising SELDI peaks were those corresponding to hepcidin-25 and ferritin light chain. We evaluated the capability of these peaks in predicting malignant and benign breast lesions using the area under the receiver operating characteristic curve (AUC). The results showed a good capacity to predict malignant breast lesions for hepcidin-25 [AUC: 0.82; 95% confidence interval (CI) 0.75-0.90] and ferritin light chain (AUC: 0.86; 95% CI 0.79-0.92). Conversely, a weak and satisfactory capability to predict benign breast lesion was observed for hepcidin-25 (AUC: 0.63; 95% CI 0.41-0.85) and ferritin light chain (AUC: 0.73; 95% CI 0.49-0.97). A significant association between HER2 status and hepcidin-25 was observed and the distribution of transferrin and ferritin were found significantly different in patients with breast cancer when compared with that of controls. CONCLUSIONS This study provides evidence that hepcidin and ferritin light chain level in plasma may be of clinical usefulness to predict malignant and benign disease with respect to healthy controls.

Abstract
The level structures of the very neutron-rich nuclei 128Pd and 126Pd have been investigated for the first time. In the r-process waiting-point nucleus 128Pd, a new isomer with a half-life of 5.8(8) μs is proposed to have a spin and parity of 8(+) and is associated with a maximally aligned configuration arising from the g(9/2) proton subshell with seniority υ=2. For 126Pd, two new isomers have been identified with half-lives of 0.33(4) and 0.44(3) μs. The yrast 2(+) energy is much higher in 128Pd than in 126Pd, while the level sequence below the 8(+) isomer in 128Pd is similar to that in the N=82 isotone 130Cd. The electric quadrupole transition that depopulates the 8(+) isomer in 128Pd is more hindered than the corresponding transition in 130Cd, as expected in the seniority scheme for a semimagic, spherical nucleus. These experimental findings indicate that the shell closure at the neutron number N=82 is fairly robust in the neutron-rich Pd isotopes.

Abstract
Myxomas of bone in the head and neck are rare tumors. We present a 68 year old female with pain and epistaxis who was found to have the first reported case of a myxoma arising within the vomer bone. Some atypical magnetic resonance imaging features are described, however, myxoma imaging features are often non-specific and typically evoke a benign differential diagnosis. Surgical excision is the treatment of choice.

Abstract
Abstract
Background. We recently demonstrated that primary breast tumors can be classified based upon extracellular matrix composition (ECM) (Bergamaschi et al.) suggesting stroma characteristics could influence tumor progression.
Aim of this study is to further investigate the robustness of this classification and its impact in tumor progression and response to therapy.
Methods. The expression profile of ECM-related genes was analyzed by unsupervised hierarchical clustering in 10 independent datasets of breast tumors, counting more than 1000 samples and the prognostic and predictive value of this signature were evaluated in two datasets of not treated patients and in one dataset of neo-adjuvant treated patients, respectively.
Results. Only one of ECM subsets (ECM3) showed a homogeneous gene pattern that consistently allowed the classification of an independent group of tumors in all tested datasets. ECM3 is characterized by highly correlated over expression of 34 ECM genes encoding mainly structural proteins. From 24 to 38% of cases were ECM3-enriched and were mainly estrogen receptor-positive and low grade (p<0.0001). The ECM3 showed inconsistent association with DMFS in the two data sets of not treated patients, whereas the interaction between ECM3 and grade showed strongly and significant association with DMFS (HR=5.35, p=0.0012). In particular, multivariate analysis of covariates available (size, ER, age and ECM) indicated that ECM3 is significantly associated with worse DMFS in grade III patients (HR=2.5, p=0.0386), whereas it is slightly correlated with better DMFS in grade I-II patients (HR=0.6, p=0.088). It is noteworthy that the probability of 10-year DMFS was 90% in ECM3 versus 74% in non-ECM3 patients in differentiated tumors, and 75% in non-ECM3 versus 41 % in ECM3 grade III tumors. The interaction between ECM3 and grade remained significantly associated with DMFS also in ER negative (HR=14.2, p=0.03) and ER positive (HR=3.34, p=0.079) subgroups. ECM3, indeed, was correlated with good and bad prognosis in differentiated and grade III tumors, respectively.
Moreover analysis of a data set of patients treated neoadjuvantly with chemotherapy revealed that, among the grade III tumors, pathological complete response was reached by 9% of ECM3 versus 74% of non-ECM3 tumors (p=0.04). In differentiated tumors no response difference was observed according to ECM.
Conclusions. Our results provide evidence that breast carcinoma progression and response to therapy are influenced by the interaction between tumor and stromal characteristics.

Abstract
The "island of inversion" nucleus 32 Mg has been studied by a (t, p) two neutron transfer reaction in inverse kinematics at REX-ISOLDE. The shape coexistent excited 0+ state in 32 Mg has been identified by the characteristic angular distribution of the protons of the Δ L=0 transfer. The excitation energy of 1058 keV is much lower than predicted by any theoretical model. The low γ-ray intensity observed for the decay of this 0+ state indicates a lifetime of more than 10 ns. Deduced spectroscopic amplitudes are compared with occupation numbers from shell-model calculations.
