Abstract
BACKGROUND This study aims to assess the role and safety of post-dilatation in protected carotid artery stenting (PCAS) using the new MicroNet-covered 2nd-generation stent assessed by cone beam CT scans. METHODS From March 2020 to March 2022, patients were enrolled in the study according to CT angiography results based on the following criteria: Evidence of 70% to 99% carotid stenosis in asymptomatic patients and 50% to 99% in symptomatic patients, per the NASCET index. Using a FilterWire EZ™ (Boston Scientific, Natick, MA, USA) embolic protection system (EPS), MicroNet-covered stent PCAS was performed by two interventional radiologists with at least 8 years of experience in endovascular intervention. Each patient underwent post-dilatation following stent placement. Finally, a third radiologist (not participating in the interventional procedures) evaluated the cone beam CT scans and calculated residual stenosis. Major and minor complications were recorded in the 30 days following the procedure. RESULTS A total of 192 patients (121 male, mean age 73±10 years) were included in the study, and all patients received post-dilatation following stent implantation. Technical successes were achieved in all procedures. Adverse events noted in this study were limited to periprocedural transient ischemic attacks that occurred in three out of 192 patients (1.6%) and showed a swift complete recovery. The post-dilatation balloon diameters used in the study were: 5.0 mm (30.3%), 5.5 mm (39.3%) and 6 mm (30.3%). Optimized postdilatation resulted in a significant increase in the final luminal area. Similar improvements were observed in all subtypes of plaque. CONCLUSIONS Post-dilatation in protected CAS is safe and induces a significant improvement in the cross-sectional area regardless of the stenotic plaque.

Abstract
INTRODUCTION Meta-analyses and emerging randomized data indicate that second-generation ('mesh') carotid stents (SGS) may improve outcomes versus conventional (single-layer) stents but clinically-relevant differences in individual SGS-type performance have been identified. No comparisons exist for SGS versus carotid endarterectomy (CEA). EVIDENCE ACQUISITION Thirty-day death (D), stroke (S), myocardial infarction (M), and 12-month ipsilateral stroke and restenosis in SGS studies were meta-analyzed (random effect model) against CEA outcomes. Eligible studies were identified through PubMed/EMBASE/COCHRANE. Forest plots were formed for absolute adverse evet risk in individual studies and for relative outcomes with each SGS deign versus contemporary CEA outcomes as reference. Meta-regression was performed to identify potential modifiers of treatment modality effect. EVIDENCE SYNTHESIS Data were extracted from 103,642 patients in 25 studies (14 SGS-treated, 41% symptomatic; nine randomized controlled trial (RCT)-CEA-treated, 37% symptomatic; and two Vascular Quality Initiative (VQI)-CEA-treated, 23% symptomatic). Casper/Roadsaver and CGuard significantly reduced DSM versus RCT-CEA (-2.70% and -2.95%, P<0.001 for both) and versus VQI-CEA (-1.11% and -1.36%, P<0.001 for both). Gore stent 30-day DSM was similar to RCT-CEA (P=0.581) but increased against VQI-CEA (+2.38%, P=0.033). At 12 months, Casper/Roadsaver ipsilateral stroke rate was lower than RCT-CEA (-0.75%, P=0.026) and similar to VQI-CEA (P=0.584). Restenosis with Casper/Roadsaver was +4.18% vs. RCT-CEA and +4.83% vs. VQI-CEA (P=0.005, P<0.001). CGuard 12-month ipsilateral stroke rate was similar to VQI-CEA (P=0.850) and reduced versus RCT-CEA (-0.63%, P=0.030); restenosis was reduced respectively by -0.26% and -0.63% (P=0.033, P<0.001). Twelve-month Gore stent outcomes were overall inferior to surgery. CONCLUSIONS Meta-analytic integration of available clinical data indicates: 1) reduction in stroke but increased restenosis rate with Casper/Roadsaver, and 2) reduction in both stroke and restenosis with CGuard MicroNET-covered stent against contemporary CEA outcomes at 30 days and 12 months used as a reference. This may inform clinical practice in anticipation of large-scale randomized trials powered for low clinical event rates (PROSPERO-CRD42022339789).

Abstract
BACKGROUND Electrocardiographic (ECG) findings in arrhythmogenic left ventricular cardiomyopathy (ALVC) are limited to small case series. OBJECTIVES This study aimed to analyze the ECG characteristics of ALVC patients and to correlate ECG with cardiac magnetic resonance and genotype data. METHODS We reviewed data of 54 consecutive ALVC patients (32 men, age 39 ± 15 years) and compared them with 84 healthy controls with normal cardiac magnetic resonance. RESULTS T-wave inversion was often noted (57.4%), particularly in the inferior and lateral leads. Low QRS voltages in limb leads were observed in 22.2% of patients. The following novel ECG findings were identified: left posterior fascicular block (LPFB) (20.4%), pathological Q waves (33.3%), and a prominent R-wave in V1 with a R/S ratio ≥0.5 (24.1%). The QRS voltages were lower in ALVC compared with controls, particularly in lead I and II. At receiver-operating characteristic analysis, the sum of the R-wave in I to II ≤8 mm (AUC: 0.909; P < 0.0001) and S-wave in V1 plus R-wave in V6 ≤12 mm (AUC: 0.784; P < 0.0001) effectively discriminated ALVC patients from controls. It is noteworthy that 4 of the 8 patients with an apparently normal ECG were recognized by these new signs. Transmural late gadolinium enhancement was associated to LPFB, a R/S ratio ≥0.5 in V1, and inferolateral T-wave inversion, and a ringlike pattern correlated to fragmented QRS, SV1+RV6 ≤12 mm, low QRS voltage, and desmoplakin alterations. CONCLUSIONS Pathological Q waves, LPFB, and a prominent R-wave in V1 were common ECG signs in ALVC. An R-wave sum in I to II ≤8 mm and SV1+RV6 ≤12 mm were specific findings for ALVC phenotypes compared with controls.

Abstract
OBJECTIVE The aim of this study is to describe the technique and to report early results of thoraco-abdominal biopsies in the Interventional Magnetic Resonance Imaging Suite (IMRIS). MATERIALS AND METHODS We prospectively evaluated patients with indications for MRI-guided biopsy between January 2021 and May 2022. Exclusion criteria were indication for US-/CT-guided biopsy, contraindication to percutaneous biopsy, inability to lie flat for at least 30 min, claustrophobic, severe obesity, or non-MRI compatible devices. Biopsies were performed by 3 interventional radiologists, with at least 8 years of experience in oncological interventional radiology. Epidemiological, clinical, procedural, and histopathological data were retrospectively collected. RESULTS From an initial population of 117 patients, 57 patients (32 male, mean age 64 ± 8 y) were finally enrolled. All 57 patients suspected thoraco-abdominal malignant lesions finally underwent MRI-guided percutaneous biopsy. The mean duration of the entire procedure was 37 min (range 28-65 min); the mean duration of the total needle-in-patient time was 10 min (range 6-19 min). Technical and clinical success were obtained for all the biopsies performed. Malignancy was demonstrated in 47/57 (82%) cases and benignancy in the remaining 10/57 (18%) cases. No major complications were detected after the biopsies; two minor compliances (severe pain) occurred and were managed conservatively. CONCLUSION Our initial experience demonstrated the technical feasibility and the accuracy of MRI-guided biopsies of thoraco-abdominal masses. The reported data associated with the best comfort for the patient and for the operator make the use of MRI a valid alternative to other methods, especially in lesions that are difficult to approach via US or CT. CLINICAL RELEVANCE STATEMENT Interventional MRI is one of the most important innovations available for interventional radiologists. This method will broaden the diagnostic and therapeutic possibilities, allowing treatment of lesions up to now not approachable percutaneously. For this, it is necessary to start publishing the data of the few groups that are developing the method. KEY POINTS • To evaluate the use of MRI as a guide for percutaneous biopsies of various districts. • Our preliminary experience confirms experience demonstrated the technical feasibility and the accuracy of MRI-guided biopsies of thoraco-abdominal masses. • Interventional MRI can become the reference method for percutaneous biopsies in particular for lesions with difficult percutaneous approach.

Abstract
AIM The aim of this prospective, multicentre, observational study was to compare the efficacy and safety of balloon-based and non-balloon-based vascular closure devices (VCDs). MATERIALS AND METHODS From March 2021 to May 2022, 2373 participants from 10 different centres were enrolled. Among them, 1672 patients with 5-7 Fr accesses were selected. Successful haemostasis, failure and safety were evaluated. Successful haemostasis was defined as the possibility to obtain complete haemostasis with the use of VCDs, without any complication. Failure management was defined as the need of manual compression. Safety was defined as the rate of complications. Cases of haematomas/pseudoaneurysms (PSA) and artero-venous fistula (AVF) were collected. RESULTS VCDs mechanism of action is statistically significant associated with the outcome. Non-balloon-based VCDs demonstrated a statistically significant better outcome: successful haemostasis was obtained in 96.5% vs. 85.9%, of cases when compared to balloon occluders (p < 0.001). The incidence of AVF was statistically more frequent using non-balloon occluders devices (1.57% vs 0%, p: 0.007). No significant statistical difference was found in comparing haematoma and PSA occurrence. Thrombocytopenia, coagulation deficit, BMI, diabetes mellitus and anti-coagulation were demonstrated to be independent predictors of failure management. CONCLUSION Our study suggests a better outcome with the same complication rate, except that for AVF incidence for non-balloon collagen plug device if compared to balloon occluders vascular closure devices.

Abstract
BACKGROUND AND OBJECTIVE The functions of an organism and its biological processes result from the expression of genes and proteins. Therefore quantifying and predicting mRNA and protein levels is a crucial aspect of scientific research. Concerning the prediction of mRNA levels, the available approaches use the sequence upstream and downstream of the Transcription Start Site (TSS) as input to neural networks. The State-of-the-art models (e.g., Xpresso and Basenjii) predict mRNA levels exploiting Convolutional (CNN) or Long Short Term Memory (LSTM) Networks. However, CNN prediction depends on convolutional kernel size, and LSTM suffers from capturing long-range dependencies in the sequence. Concerning the prediction of protein levels, as far as we know, there is no model for predicting protein levels by exploiting the gene or protein sequences. METHODS Here, we exploit a new model type (called Perceiver) for mRNA and protein level prediction, exploiting a Transformer-based architecture with an attention module to attend to long-range interactions in the sequences. In addition, the Perceiver model overcomes the quadratic complexity of the standard Transformer architectures. This work's contributions are 1. DNAPerceiver model to predict mRNA levels from the sequence upstream and downstream of the TSS; 2. ProteinPerceiver model to predict protein levels from the protein sequence; 3. Protein&DNAPerceiver model to predict protein levels from TSS and protein sequences. RESULTS The models are evaluated on cell lines, mice, glioblastoma, and lung cancer tissues. The results show the effectiveness of the Perceiver-type models in predicting mRNA and protein levels. CONCLUSIONS This paper presents a Perceiver architecture for mRNA and protein level prediction. In the future, inserting regulatory and epigenetic information into the model could improve mRNA and protein level predictions.

Abstract
Radiofrequency (RF) catheter ablation has become a widely used therapeutic approach. However, long-term results in terms of arrhythmia recurrence are still suboptimal. Cardiac magnetic resonance (CMR) could offer a valuable tool to overcome this limitation, with the possibility of targeting the arrhythmic substrate and evaluating the location, depth, and possible gaps of RF lesions. Moreover, real-time CMR-guided procedures offer a radiation-free approach with an evaluation of anatomical structures, substrates, RF lesions, and possible complications during a single procedure. The first steps in the field have been made with cavotricuspid isthmus ablation, showing similar procedural duration and success rate to standard fluoroscopy-guided procedures, while allowing visualization of anatomic structures and RF lesions. These promising results open the path for further studies in the context of more complex arrhythmias, like atrial fibrillation and ventricular tachycardias. Of note, setting up an interventional CMR (iCMR) centre requires safety and technical standards, mostly related to the need for CMR-compatible equipment and medical staff's educational training. For the cardiac imagers, it is fundamental to provide correct CMR sequences for catheter tracking and guide RF delivery. At the same time, the electrophysiologist needs a rapid interpretation of CMR images during the procedures. The aim of this paper is first to review the logistic and technical aspects of setting up an iCMR suite. Then, we will describe the experience in iCMR-guided flutter ablations of two European centres, Policlinico Casilino in Rome, Italy, and Haga Teaching Hospital in The Hague, the Netherlands.

Abstract
This article summarizes the main electrocardiogram (ECG) findings in dilated cardiomyopathy (DCM) patients. Recent reports are described in the great 'pot' of DCM peculiar ECG patterns that are typical of specific forms of DCM. Patients with late gadolinium enhancement on CMR, who are at greatest arrhythmic risk, have also distinctive ECG features. Future studies in large DCM populations should evaluate the diagnostic and prognostic value of the ECG.

Abstract
Magnetic resonance (MR) represents a new interesting imaging approach for guiding electrophysiology (EP)-based ablation procedures of atrial flutter and typical atrial fibrillation. This new approach permits to reach good results if compared with conventional EP ablation. Tissue characterization by MR permits to detect cardiac anatomy and pathological substrate like myocardial scars well visualized with late gadolinium enhancement (LGE) sequences. Intra-procedural imaging is useful to real-time follow the catheter during the ablation procedure and at the same time to visualize cardiac anatomy in addition to understanding if the ablation is correctly performed using oedema sequences. Performing cardiac ablations inside an MR room permits to reduce radiation exposure and occupational illnesses.

Abstract
Criteria for diagnosis of arrhythmogenic cardiomyopathy (ACM) were first proposed in 1994 and subsequently revised in 2010 and in 2020 by an international task force. According to the last consensus of 2020, ACM is defined as a heart muscle disease affecting right ventricle, left ventricle or both, whose principal pathologic feature is fibrofatty myocardial replacement that impairs systolic ventricular function and predisposes to lethal ventricular arrhythmias. ECG findings not only could help to early recognize affected patients but also could identify the ones with maximum risk of ventricular arrhythmias and sudden cardiac death.

Abstract
Fabry disease (FD) is a rare X-linked inherited lysosomal storage disorder caused by deficient a-galactosidase A activity that leads to an accumulation of glycolipids, mainly globotriaosylceramide (Gb3) and globotriaosylsphingosine, in affected tissues, including the heart. Cardiovascular involvement usually manifests as left ventricular hypertrophy (LVH), myocardial fibrosis, heart failure, and arrhythmias, which limit the quality of life and represent the most common causes of death. Following the introduction of enzyme replacement therapy, early diagnosis and treatment have become essential in slowing down the disease progression and preventing major cardiac complications. Recent advances in the understanding of FD pathophysiology suggest that in addition to Gb3 accumulation, other mechanisms contribute to the development of cardiac damage. FD cardiomyopathy is characterized by an earlier stage of glycosphingolipid accumulation and a later one of hypertrophy. Morphological and functional aspects are not specific in the echocardiographic evaluation of Anderson-Fabry disease. Cardiac magnetic resonance with tissue characterization capability is an accurate technique for the differential diagnosis of LVH. Progress in imaging techniques has improved the diagnosis and staging of FD-related cardiac disease: a decreased myocardial T1 value is specific of FD. Late gadolinium enhancement is typical of the later stage of cardiac involvement but as in other cardiomyopathy is also valuable to predict the outcome and cardiac response to therapy.

Abstract
PURPOSE Carotid revascularization can be associated with modifications of the vascular geometry, which may lead to complications. The changes on the vessel angulation before and after a carotid WallStent (WS) implantation are compared against 2 new dual-layer devices, CGuard (CG) and RoadSaver (RS). MATERIALS AND METHODS The study prospectively recruited 217 consecutive patients (112 GC, 73 WS, and 32 RS, respectively). Angiography projections were explored and the one having a higher arterial angle was selected as a basal view. After stent implantation, a stent control angiography was performed selecting the projection having the maximal angle. The same procedure is followed in all the 3 stent types to guarantee comparable conditions. The angulation changes on the stented segments were quantified from both angiographies. The statistical analysis quantitatively compared the pre-and post-angles for the 3 stent types. The results are qualitatively illustrated using boxplots. Finally, the relation between pre- and post-angles measurements is analyzed using linear regression. RESULTS For CG, no statistical difference in the axial vessel geometry between the basal and postprocedural angles was found. For WS and RS, statistical difference was found between pre- and post-angles. The regression analysis shows that CG induces lower changes from the original curvature with respect to WS and RS. CONCLUSION Based on our results, CG determines minor changes over the basal morphology than WS and RS stents. Hence, CG respects better the native vessel anatomy than the other stents.Level of Evidence: Level 4, Case Series.

Abstract
Connecting Vision and Language plays an essential role in Generative Intelligence. For this reason, large research efforts have been devoted to image captioning, i.e. describing images with syntactically and semantically meaningful sentences. Starting from 2015 the task has generally been addressed with pipelines composed of a visual encoder and a language model for text generation. During these years, both components have evolved considerably through the exploitation of object regions, attributes, the introduction of multi-modal connections, fully-attentive approaches, and BERT-like early-fusion strategies. However, regardless of the impressive results, research in image captioning has not reached a conclusive answer yet. This work aims at providing a comprehensive overview of image captioning approaches, from visual encoding and text generation to training strategies, datasets, and evaluation metrics. In this respect, we quantitatively compare many relevant state-of-the-art approaches to identify the most impactful technical innovations in architectures and training strategies. Moreover, many variants of the problem and its open challenges are discussed. The final goal of this work is to serve as a tool for understanding the existing literature and highlighting the future directions for a research area where Computer Vision and Natural Language Processing can find an optimal synergy.

Abstract
mAbs, either mono- or bispecific (bsAb), represent one of the most successful approaches to treat many types of malignancies. However, there are certain limitations to the use of full length mAbs for clinical applications, which can be overcome by engineered antibody fragments. The aim of this study was to develop a small bsAb, in the format of a single-chain diabody (scDb), to efficiently target two proteins, the hERG1 potassium channel and the β1 subunit of integrin receptors, which specifically form a macromolecular complex in cancer cells. We provide evidence that the scDb we produced binds to the hERG1/β1 complex in cancer cells and tissues, but does not bind to the hERG1 channel in nonpathologic tissues, in particular the heart. The scDb-hERG1-β1 (i) downregulates the formation of the hERG1/β1 complex, (ii) inhibits Akt phosphorylation and HIF-1α expression, and (iii) decreases cell survival, proliferation, and migration in vitro These effects only occur in cancer cells (either colon, pancreatic, or breast), but not in normal cells. In vivo, the scDb-hERG1-β1 shows a good pharmacokinetic profile, with a half-life of 13.5 hours and no general, cardiac, or renal toxicity when injected intravenously up to the dose of 8 mg/kg. The scDb-hERG1-β1 accumulates into subcutaneous xenografted tumors, arising from either colon or pancreatic human cancer cells, and induces a reduction of tumor growth and vascularization. Overall, the scDb-hERG1-β1 represents an innovative single-chain bispecific antibody for therapeutic applications in solid cancers that overexpress the hERG1/β1 integrin signaling complex.

Abstract
The study aimed to evaluate clinical and vascular characteristics, as well as outcomes, for diabetic persons with foot ulceration and no-option critical limb ischemia (CLI). The study group included a sample of patients admitted to our diabetic foot unit because of a new diabetic foot ulcer and CLI. All subjects were managed using a limb salvage protocol which includes lower-limb revascularization. According to whether or not the revascularization procedure was a success, patients were respectively divided into two groups: successfully treated CLI patients (ST-CLI) and no-option CLI patients (NO-CLI). Failed revascularization was considered in the case of technical recanalization failure of occluded vessels (inability to overcome the obstruction) and/or absence of arterial flow to the foot. Limb salvage, major amputation, and death after 1 year of follow-up were evaluated and compared between the two groups. Overall, 239 patients were included, 74.9% belonging to ST-CLI and 25.1% to NO-CLI. NO-CLI patients reported more cases of ischemic heart disease (80 vs. 62.1, p = 0.008), heart failure (63.3 vs. 32.4%, p < 0.0001), and end-stage renal disease (ESRD) (60 vs. 25.7%) than ST-CLI patients. In addition, more vessels were affected in the NO-CLI group (5.2 ± 1.6 vs. 4 ± 1.5, p < 0.0001), and there was more involvement of tibio-peroneal trunk (50 vs. 30.2%, p = 0.006), anterior tibial (93.3 vs. 82.7, p = 0.03), posterior tibial (93.3 vs. 73.7%, p = 0.0005), peroneal (70 vs. 48%, p = 0.002), and below-the-ankle arteries (73.3 vs. 39.1%, p < 0.0001) than ST-CLI. The 1 year outcomes for the whole population were 69.9% limb salvage, 10.9% major amputation, and 19.2% death. The outcomes for NO-CLI and ST-CLI were, respectively, as follows: limb salvage (13.8 vs. 73.4%, p < 0.0001), amputation (30 vs. 4.5%, p = 0.0001), and mortality (50 vs. 8.9%, p < 0.0001). NO-CLI patients showed a more severe pattern of peripheral arterial disease (PAD) with distal arterial lesions and worse outcomes than ST-CLI.

Abstract
Macrolide antibiotics, such as Clarithromycin (Cla), have been proven to exert anti-tumour activity in several preclinical models of different types of cancer. Cla can exert its anti-tumour effects through different mechanisms, e.g. by blocking the autophagic flux, inducing apoptosis or inhibiting tumour-induced angiogenesis. The clinical benefit of Cla in treating various tumours in combination with conventional treatment was confirmed in extensive clinical studies in patients suffering from non-small cell lung cancer, breast cancer, multiple myeloma and other haematological malignancies. Data regarding the anti-cancer effect of Cla on Colorectal Cancer (CRC) are still lacking. This article shares data on the in vivo efficacy of Cla in two xenograft models of CRC. Our results show that Cla treatment reduces tumour growth and increases the overall survival in CRC mouse xenograft models. Moreover, the Western blot analysis of autophagic and apoptotic markers suggests that the anti-tumour effects of Cla are related to a modulation of both cellular processes. The data suggest that it will worth consider Cla as treatment option for CRC patients.

Abstract
In recent years, a few successful attempts were made to repurpose the clinically approved antiarthritic gold drug, Auranofin (AF), as an anticancer agent. The present study shows that the iodido(triethylphosphine)gold(I) complex, (Et 3 PAuI hereafter)-an AF analogue where the thiosugar ligand is simply replaced by one iodide ligand-manifests a solution chemistry resembling that of AF and exerts similar cytotoxic and proapoptotic effects on A2780 human ovarian cancer cells in vitro. However, when evaluated in a preclinical orthotopic model of ovarian cancer, Et 3 PAuI produces a far superior anticancer action than AF inducing a nearly complete tumor remission. The highly promising in vivo performances here documented for Et 3 PAuI warrant its further evaluation as a drug candidate for ovarian cancer treatment.

Abstract
The genetics-assisted program for resistance to biotic stresses began at the Edmund Mach Foundation in 2007 and has developed on two lines. The first line was based on obtaining resistant materials with parents the historical varieties of Trentino. During the three-year period 2015–2017, 3 Teroldego X Merzling genotypes, 3 Marzemino X Merzling genotypes, 1 Nosiola X Bianca genotype and 1 Nosiola X Kulneany genotype were collected the data related to resistance to various fungal diseases both on the leaf and on the bunch. At harvest the plant production data and the must characteristics were recorded; the grapes were vinified and for each year the wines were subjected to sensorial analysis. 5 resistant selections were considered interesting for all the characteristics found and therefore the data for the registration to the National Register of Grapevine Varieties will be collected. The second line of research was based on the retrieval and both genotypic and phenotypic characterization of potentially parental lines acquired from foreign breeding programs and of wild materials. Once the crossings have been planned and obtained, the evaluation of the progeny takes place following a process of Marker-Assisted Selection optimized in order to maintain a compromise between efficiency and cost containment.

Abstract
In southern Brazil there is a predominance of labrusca and hybrid varieties for wine and juice production due to climatic conditions of high rainfall, temperature and relative humidity. Growing varieties that combine disease resistance and wine quality (PIWI) can be an alternative to improve wine quality. The objective of this work was to evaluate the performance of three PIWI varieties (Felicia, Calardis Blanc and Aromera) in two regions (Videira, 27∘01′S and 51∘08′W, altitude 830 m; and São Joaquim, 28∘13′S and 50∘04′W, altitude 1100 m) in the vintage 2018. The date of occurrence of main phenological stages, productiveindexes, clusters characteristics and grape qualitative indexes was evaluated. There was no difference for budbreak date, but flowering, veraison an maturity time varied between regions. The development of plants is slower when they are cultivated at a higher altitude. The number of clusters per plant and yield were higher at 830 m for all varieties. For productive indexes Felicia and Calardis Blanc varieties stood out in relation to Aromera in all parameters. Among the evaluated varieties, Felicia and Calardis Blanc were better adapted to the lower altitude region and had higher productivity and the same grape quality. On the other hand, Aromera presented higher productivity at 830 m but higher soluble solids content at 1100 m.

Abstract
Spontaneous chromosomal fragility was detected in seven tumor patients and one healthy member from two families with a high recurrence of cancer. Major chromosome lesions, such as terminal deletions and rearranged chromosomes, were found at levels significantly higher than those reported for control individuals. The prevalence of these aberrations in comparison to minor ones (chromosome gaps and chromatid breaks) in this group ofpatients seems to indicate that the fragility observed is the end-point of a process of chromosomal instability, which may have already been brought to expression. Study of other parameters of genetic instability in the most unstable karyotypes showed that the chromosome damage observed was neither paralleled by abnormal SCE frequency nor sustained by defective DNA repair mechanisms or expression of inherited or constitutional fragile sites. As all the subjects investigated here had previously been shown to display intraindividual variations in the C-banded region of chromosome 1, it is possible that spontaneous fragility and acquired C-heterochromatin polymorphism may be markers that, combined with chromosomal instability, create genetic predisposition to cancer.

Abstract
The solution behavior of auranofin, Et3PAuCl and Et3PAuI, as well as their interactions with hen egg white lysozyme, single strand oligonucleotide, and ds-DNA were comparatively analyzed through NMR spectroscopy, ESI-MS, ethidium bromide displacement, DNA melting and viscometric tests. The cytotoxic effects toward representative colorectal cancer cell lines were found to be strong and similar in the three cases and a good correlation could be established between the cytotoxicity and the ability to inhibit thioredoxin reductase; remarkably, in vivo acute toxicity experiments for Et3PAuI confirmed that, similarly to auranofin, this drug is well tolerated in a murine model. Overall, a very similar profile emerges for Et3PAuI and Et3PAuCl, which retain the potent cytotoxic effects of auranofin while showing some peculiar features. These results demonstrate that the presence of the thiosugar moiety is not mandatory for the pharmacological action, suggesting that the tuning of some relevant chemical properties such as lipophilicity could be exploited to improve bioavailability, with no loss of the pharmacological effects.

Abstract
The aim of this parallel double-blind randomized controlled clinical trial was to describe a modified approach using the coronally advanced flap (CAF) with triangular design and to compare its efficacy, in terms of root coverage and esthetics, with a trapezoidal type of CAF. A sample of 50 isolated Miller Class I and II gingival recessions with at least 1 mm of keratinized tissue apical to the defects were treated with CAF. Of these recessions, 25 were randomly treated with trapezoidal CAF (control group) while the other 25 (test group) were treated with a modified triangular CAF. The clinical and esthetic evaluations, made by the patient and an independent periodontist, were performed 3 months, 6 months, and 1 year after the surgery. No statistically significant difference was demonstrated between the two CAF groups in terms of recession reduction, complete root coverage, or 6-month and 1-year patient esthetic scores. Better 3-month patient esthetic evaluations and better periodontist root coverage, color match, and contiguity assessments were reported after triangular CAF. Trapezoidal CAF was associated with greater incidence of keloid formation. Single-type gingival recessions can be successfully covered with both types of CAF. The triangular CAF should be preferred for esthetically demanding patients.

Abstract
BACKGROUND AND PURPOSE Noncontrast CT ASPECTS has been investigated as a predictor of outcome in patients with acute ischemic stroke. Our purpose was to investigate whether CTA source images are a better predictor of clinical and radiologic outcomes than NCCT ASPECTS in candidates for endovascular stroke therapy. MATERIALS AND METHODS CT scans of patients (n = 124) were independently evaluated by 2 readers for baseline NCCT and CTA source image ASPECTS and for follow-up ASPECTS. An mRS of ≤2 at 3 months was considered a favorable outcome. Receiver operating characteristic curve analysis was used to assess the ability of NCCT and CTA source image ASPECTS to identify patients with favorable outcomes. A stepwise multiple regression analysis was performed to find independent predictors of outcome. RESULTS Baseline CTA source image ASPECTS correlated better than NCCT ASPECTS with follow-up ASPECTS (r = 0.76 versus r = 0.51; P for comparison of the 2 coefficients < .001). Receiver operating characteristic curve analysis showed that baseline CTA source image ASPECTS compared with NCCT ASPECTS can better identify patients with favorable outcome (CTA source image area under the curve = 0.83; 95% CI, 0.76-0.91; NCCT area under the curve = 0.67; 95% CI, 0.58-0.77; P < .001). Finally, the stepwise regression analysis showed that lower age, good recanalization, lower time to recanalization, and good baseline CTA source image ASPECTS, not NCCT ASPECTS, were independent predictors of favorable outcome. CONCLUSIONS CTA source image ASPECTS predicts outcome better than NCCT ASPECTS; this finding suggests CTA rather than NCCT as a main step in the decision-making process for patients with acute ischemic stroke.

Abstract
Ion channels regulate cell proliferation, differentiation, and migration in normal and neoplastic cells through cell-cell and cell-extracellular matrix (ECM) transmembrane receptors called integrins. K+ flux through the human ether-à-go-go-related gene 1 (hERG1) channel shapes action potential firing in excitable cells such as cardiomyocytes. Its abundance is often aberrantly high in tumors, where it modulates integrin-mediated signaling. We found that hERG1 interacted with the β1 integrin subunit at the plasma membrane of human cancer cells. This interaction was not detected in cardiomyocytes because of the presence of the hERG1 auxiliary subunit KCNE1 (potassium voltage-gated channel subfamily E regulatory subunit 1), which blocked the β1 integrin-hERG1 interaction. Although open hERG1 channels did not interact as strongly with β1 integrins as did closed channels, current flow through hERG1 channels was necessary to activate the integrin-dependent phosphorylation of Tyr397 in focal adhesion kinase (FAK) in both normal and cancer cells. In immunodeficient mice, proliferation was inhibited in breast cancer cells expressing forms of hERG1 with impaired K+ flow, whereas metastasis of breast cancer cells was reduced when the hERG1/β1 integrin interaction was disrupted. We conclude that the interaction of β1 integrins with hERG1 channels in cancer cells stimulated distinct signaling pathways that depended on the conformational state of hERG1 and affected different aspects of tumor progression.

Abstract
BACKGROUND The aim of this study is to evaluate the risk of contrast induced nephropathy (CIN) in diabetic patients with critical limb ischemia (CLI) and foot ulcers (FUs) treated by percutaneous transluminal angioplasty of lower limbs. METHODS The study group was composed of 145 diabetic patients who underwent a limb salvage protocol because of CLI and FUs between 2012 and 2015. All patients received a prophylactic strategy against the administration of contrast medium. Serum creatinine (SCr) levels were evaluated the day of procedure and for 3 days after. CIN was considered in case of increase of 25% of SCr in comparison to baseline value or an absolute increase of at least 0.5 mg/dl without other interfering factors. RESULTS CIN occurred in 9% (14/145) of the cases. In the 1-year follow-up SCr returned to baseline values in 10 patients (71 %), 3 patients died (21%), and 1 patient had a major cardiovascular event (7%). No patients required dialysis. The risk was independent of chronic kidney disease stage. The rate of contrast nephropathy in each stage (X = 0.27) was as follows: 3/20 (15%) in stage 2; 3/66 (4.6%) in stage 3, 7/51 (13.7%) in stage 4; and 1/8 (12.5%) in stage 5. At the univariate analysis factors predicting this risk were anemia (HR 95% 2.5 [CI 1.8-4.2] P = .039) and heart failure (HR 95% 2.6 [CI 2.1-4.6] P = .038), while any significant variable was found at multivariate analysis. CONCLUSIONS Peripheral percutaneous transluminal angioplasty in diabetic patients with CLI and FUs can be performed with a good safety factor and a low risk of contrast medium toxicity.

Abstract
AIM To evaluate the outcomes of diabetic dialysis patients with critical limb ischemia and foot ulcer. METHODS The study group included 599 diabetic, 99 dialyzed (Ds) (16.5%) and 500 not dialyzed (NDs) (83%) patients with critical limb ischemia and foot ulcers identified as stage C (ischemia) or D (ischemia plus infection) of Texas Wound Classification. All patients were treated by endovascular revascularization. Outcomes were expressed as healing, major amputation, death and non healing after 12months. The mean follow-up was 15±13months. RESULTS The outcomes of the whole population were: 48.9% healing, 11.3% major amputation, 12.7% death, 27.1 non healing. At the multivariate analysis dialysis was a negative predictor of healing and a positive predictor of major amputation. Outcomes for Ds and NDs were respectively: healing (30.3 vs 52.6%), major amputation (14.4 vs 10.8%), death (21.1 vs 11%) and non-healing (34.2 vs 25.6%) (X=0.0004). Amputation occurred earlier in Ds than in NDs. According to the multivariate analysis in Ds ischemic heart disease and lower ΔTcPO2 were negative predictors for healing. Successful revascularization was a negative predictor for major amputation. HDL and carotid artery disease were predictive factors of death among NDs. Among Ds high blood pressure values were the only predictor of amputation while no variable resulted predictive of healing or death. CONCLUSIONS Our study shows that our limb salvage protocol ensures a good rate of limb salvage in Ds even if they have a higher risk of amputation and death compared to NDs.

Abstract
PURPOSE To illustrate the use of a mechanical thromboaspiration device originally designed for clot retrieval in acute stroke in the treatment of acute distal embolism occurring during percutaneous revascularization of the femoropopliteal and below-the-knee arterial segments. TECHNIQUE The Penumbra system was adapted for aspiration of thrombus in the distal foot arteries as a standalone device. The 2 over-the-wire, tapered lumen catheters have long working lengths (139 cm for the 4MAX to 153 cm for the 3MAX) that allow advancement below the ankle even with a retrograde contralateral approach. Once the occluded arterial segment is reached, the catheters are connected to the dedicated pump for continuous vacuum aspiration. The use of the device is illustrated in 3 diabetic patients (1 woman and 2 men; ages 88, 70, and 73 years, respectively) undergoing limb salvage procedures who experienced distal embolization that would have seriously jeopardized the foot circulation. The lumens of the occluded arteries were restored without complication. CONCLUSION While further evaluation in a larger cohort of patients is needed, this initial experience using the Penumbra system in the peripheral vasculature suggests that this is a rapid, effective approach to address intraprocedural foot embolization and avoid possible grave clinical sequelae.

Abstract
PURPOSE To investigate the feasibility of real-time sonoelastography in the assessment of the mechanical tendon properties in small unilateral supraspinatus tears, to describe the sonoelastographic properties of the torn supraspinatus tendons and to correlate real-time sonoelastography findings with clinical results and demographic data. METHODS All the patients presenting for a unilateral rotator cuff tear were prospectively scrutinized. Clinical evaluation included complete physical examination, VAS, Quick DASH, Constant-Murley score, Simple Shoulder Test, ASES score and UCLA score. Radiological evaluation was performed with conventional ultrasounds and real-time sonoelastography; this is a noninvasive method that uses ultrasounds to evaluate the mechanical properties of tissues, reflecting their quality, that can be semi-quantitatively estimated using the strain index. During the enrolment period, 92 patients were scrutinized, and 50 were included in the study. RESULTS A negative correlation between strain index and VAS for pain, a strong positive correlation between strain index and Constant-Murley score and ASES score were found. Comparable results were observed in male and female patients, but in males, we found a strong positive correlation also for Simple Shoulder Test and UCLA score. CONCLUSIONS Real-time sonoelastography was a feasible method applicable in the assessment of tendon quality in small supraspinatus tears, and its findings correlated with the clinical results of the patients. In day-by-day clinical practice, this information is very important because quality of tendons is one of the most important prognostic factors for surgeons performing rotator cuff repair.

Abstract
The purpose of this work has been to dosimetrically investigate four fluoroscopically guided interventions: the percutaneous vertebroplasty (PVP), the percutaneous disc decompression (PDD), the radiofrequency medial branch neurolysis (RF) (hereafter named spine procedures), and the endovascular treatment for the critical limb ischemia (CLI). The X-ray equipment used was a Philips Integris Allura Xper FD20 imaging system provided with a dose-area product (DAP) meter. The parameters investigated were: maximum skin dose (MSD), air kerma (Ka,r), DAP, and fluoroscopy time (FT). In order to measure the maximum skin dose, we employed a system based on MOSFET detectors. Before using the system on patients, a calibration factor Fc and correction factors for energy (CkV) and field size (CFD) dependence were determined. Ka,r, DAP, and FT were extrapolated from the X-ray equipment. The analysis was carried out on 40 patients, 10 for each procedure. The average fluoroscopy time and DAP values were compared with the reference levels (RLs) proposed in literature. Finally, the correlations between MSD, FT, Ka,r, and DAP values, as well as between DAP and FT values, were studied in terms of Pearson's product-moment coefficients for spine procedures only. An Fc value of 0.20 and a very low dependence of CFD on field size were found. A third-order polynomial function was chosen for CkV. The mean values of MSD ranged from 2.3 to 10.8cGy for CLI and PVP, respectively. For these procedures, the DAP and FT values were within the proposed RL values. The statistical analysis showed little correlation between the investigated parameters. The interventional procedures investigated were found to be both safe with regard to deterministic effects and optimized for stochastic ones. In the spine procedures, the observed correlations indicated that the estimation of MSD from Ka,r or DAP was not accurate and a direct measure of MSD is therefore recommended.

Abstract
'Iatrogenic anemia' is a condition of lowered hematocrit and hemoglobin count resulting from large or frequent removal of blood samples, usually for laboratory testing. It is frequently seen in patients who are already suffering from bone marrow depression, and thus may become a comorbidity. Because several different types of chemical agents may be required for test procedures, a large volume of blood could be removed for each set of testing, perhaps 50-60 mL. Often local and reference laboratories request larger samples than are really necessary to perform a given test and still have some left to perform any required repeat testing. My experience shows that a volume of about 3 mL of each type of sample should be sufficient for this purpose.

Abstract
BACKGROUND Xeroderma pigmentosum (XP) is a rare autosomal recessive disorder of DNA repair. It is divided into eight complementation groups: XP-A to XP-G (classical XP) and XP variant (XP-V). Severe and prolonged sunburn reactions on minimal sun exposure have been considered a cardinal feature of classical XP. However, it has recently become clear that not all patients have abnormal sunburn reactions. OBJECTIVES To examine sunburn reactions in a cohort of patients with XP and correlate this to the complementation group. METHODS Sixty patients with XP attending the U.K. National XP Service from 2010 to 2012 were studied. Their history of burning after minimal sun exposure was assessed using a newly developed sunburn severity score. The age at which the first skin cancer was histologically diagnosed in each patient, and the presence of any neurological abnormality, was also recorded. RESULTS Sunburn severity scores were abnormally high in patients with XP-A, XP-D, XP-F and XP-G compared with non-XP controls. There was no significant difference in sunburn score of patients with XP-C, XP-E and XP-V compared with controls (P > 0·05). Patients with XP-C, XP-E and XP-V were more likely to have skin cancer diagnosed at an earlier age than those with severe sunburn on minimal sun exposure. In addition, patients with XP with severe sunburn had an increased frequency of neurological abnormalities. CONCLUSIONS Not all patients with XP have a history of severe and prolonged sunburn on minimal sun exposure. The normal sunburn response of patients with XP-C, XP-E and XP-V may relate to the preservation of transcription-coupled DNA repair in these groups. Those with a history of severe sunburn on minimal sun exposure developed their first skin cancer at an older age compared with patients with XP-C, XP-E and XP-V, but they had an increased frequency of neurological abnormalities. Physicians need to be aware that about half of all patients with XP will present without a history of abnormal sunburn.

Abstract
BACKGROUND AND PURPOSE Hypothetical correlation between chronic cerebrospinal venous insufficiency and MS has gained the attention of patients and the scientific community. Studies performed by echo-color Doppler ultrasonography have shown different results, and it is necessary to use more objective diagnostic techniques. The aim of our study was to evaluate the presence of stenoses affecting azygos veins and internal jugular veins by use of venography in patients with MS. MATERIALS AND METHODS We recruited 2 groups of subjects who underwent venography: the study group included 29 patients with MS and the control group included 15 healthy volunteers. The ileo-lumbar plexus, the azygos, and the internal jugular veins were selectively catheterized. We considered any cross-sectional area reduction of the venous lumen >50% to be a significant stenosis. Furthermore, blood pressure was measured in the studied vessels at the stenotic internal jugular veins. RESULTS Selective venography showed at least 1 significant venous stenosis in 84% of subjects examined, without significant difference between the study group and the control group. Positive venography chronic cerebrospinal venous insufficiency patterns were found in 50% of all subjects examined, without any significant difference between the 2 groups. The multivariate logistic regression analysis failed to assess any significant association between the presence of a positive venography and MS condition. The difference between the median blood pressure of stenotic and nonstenotic internal jugular veins was not statistically significant (P = .46). CONCLUSIONS Our data exclude any direct correlation between chronic cerebrospinal venous insufficiency and MS because venous abnormalities were equally present in both groups.

Abstract
PURPOSE hERG1 channels are aberrantly expressed in several types of human cancers, where they affect different aspects of cancer cell behavior. A thorough analysis of the functional role and clinical significance of hERG1 channels in gastric cancer is still lacking. EXPERIMENTAL DESIGN hERG1 expression was tested in a wide (508 samples) Italian cohort of surgically resected patients with gastric cancer, by immunohistochemistry and real-time quantitative PCR. The functional link between hERG1 and the VEGF-A was studied in different gastric cancer cell lines. The effects of hERG1 and VEGF-A inhibition were evaluated in vivo in xenograft mouse models. RESULTS hERG1 was positive in 69% of the patients and positivity correlated with Lauren's intestinal type, fundus localization of the tumor, G1-G2 grading, I and II tumor-node-metastasis stage, and VEGF-A expression. hERG1 activity modulated VEGF-A secretion, through an AKT-dependent regulation of the transcriptional activity of the hypoxia inducible factor. Treatment of immunodeficient mice xenografted with human gastric cancer cells, with a combination of hERG1 blockers and anti-VEGF-A antibodies, impaired tumor growth more than single-drug treatments. CONCLUSION Our results show that hERG1 (i) is aberrantly expressed in human gastric cancer since its early stages; (ii) drives an intracellular pathway leading to VEGF-A secretion; (iii) can be exploited to identify a gastric cancer patients' group where a combined treatment with antiangiogenic drugs and noncardiotoxic hERG1 inhibitors could be proposed.

Abstract
According to Italian legislation to diagnose brain death (BD) after the initial documentation of the clinical signs, repetition of clinical testing and confirmation of the loss of bioelectrical activity of the brain (EEG) is required. However, when EEG is unreliable it is necessary to demonstrate cerebral circulatory arrest (CCA). Accepted imaging techniques to demonstrate CCA include: cerebral angiography, cerebral scintigraphy, transcranial Doppler (TCD) and computed tomography angiography (CTA). This latter technique, due to its large availability, low invasivity and easy and fast acquisition is widely used over the country. Nevertheless its diagnostic reliability is affected by some limitations in patients with decompressive craniectomy. Here we report two cases of brain injury with clinical signs of BD and at the same time, opacification of intracranial arteries on CTA and a pattern consistent with flow arrest on the corresponding insonable arteries on TCD. The discrepancy between CTA and TCD results points out a methodology limitation that could be overcome by updating Italian legislation according to other European Countries legislation.

Abstract
Ischemic stroke is the third leading cause of death and most common cause of permanent disability in industrialized nations. Eighty-five percent of strokes are ischemic in nature, with an associated mortality between 53% and 92%. The focus of treatment for acute stroke starts with prompt and accurate diagnosis of ischemic brain tissue at risk, followed by time sensitive delivery of therapy that effectively and safely restores flow to that vascular territory. Time-dependent reperfusion therapy is the only proven treatment for Acute Ischemic Stroke. In this paper, we review the clinical and imaging factors that are relevant to guide endovascular treatment decisions; the different approaches of stroke therapy and the devices used with the goal of obtaining the most rapid and complete recanalization possible, while minimizing vascular damage and hemorrhagic complications. It is paid particular attention to indications and outcomes of the different endovascular stroke therapy devices use, as defined in major clinical trials or current clinical practice. Anterior circulation strokes represent the primary focus of this review.

Abstract
PURPOSE To investigate the relationship between chronic cerebrospinal venous insufficiency (CCSVI) and cerebral hemodynamic parameters and to disclose any possible involvement in the pathophysiology of multiple sclerosis (MS). MATERIALS AND METHODS The study was approved by the institutional review board, and written informed consent was obtained from all participants. The diagnosis of CCSVI was assigned by using specific color Doppler ultrasonographic criteria. Cerebral blood volume (CBV), cerebral blood flow (CBF), and mean transit time were assessed with dynamic susceptibility contrast material-enhanced magnetic resonance imaging in normal-appearing white matter (NAWM) in 39 patients with MS. Of these, 25 had CCSVI and 14 did not. Twenty-six healthy control subjects were also evaluated, and of these, 14 had CCSVI and 12 did not. Two-way analysis of variance testing was used for statistical analysis, with Bonferroni correction for multiple comparisons. Correlation analysis was performed by calculating Spearman coefficients. RESULTS Individuals with CCSVI showed cerebral hemodynamic anomalies, such as decreased CBF and CBV, as compared with individuals without CCSVI, without any delay in mean transit time. No significant interaction between MS and CCSVI was found for any hemodynamic parameters. Furthermore, no correlations were found between CBV and CBF values in NAWM or for severity of disability in patients with MS. The MS group showed prolonged mean transit time in the periventricular NAWM, as compared with the control group, and positive correlation was found between mean transit time values and disability scales in patients with MS. CONCLUSION The data support a role of CCSVI in cerebral hemodynamic changes, such as a decrease of CBV and CBF, regardless of the presence of MS. CCSVI had no effect on neurologic function and disability progression in patients with MS.

Abstract
PURPOSE To describe a technique to recanalize occluded superficial femoral artery (SFA) stents without inflow or outflow in patients with proximal SFA obstruction. TECHNIQUE After a failed attempt to engage an occluded stent through an antegrade femoral approach, a distal retrograde puncture of the proximal part of the stent was performed. After subintimal rendezvous with a catheter advanced from the antegrade access, in-stent angioplasty can be performed to recanalize the stent and SFA. CONCLUSION Direct retrograde puncture of an occluded stent may be considered an approach to recanalization in patients with stent occlusion and no inflow or outflow.
