Abstract
Thermal dark matter models with particle χ masses below the electroweak scale can provide an explanation for the observed relic dark matter density. This would imply the existence of a new feeble interaction between the dark and ordinary matter. We report on a new search for the sub-GeV χ production through the interaction mediated by a new vector boson, called the dark photon A^{'}, in collisions of 100 GeV electrons with the active target of the NA64 experiment at the CERN SPS. With 9.37×10^{11} electrons on target collected during 2016-2022 runs NA64 probes for the first time the well-motivated region of parameter space of benchmark thermal scalar and fermionic dark matter models. No evidence for dark matter production has been found. This allows us to set the most sensitive limits on the A^{'} couplings to photons for masses m_{A^{'}}≲0.35 GeV, and to exclude scalar and Majorana dark matter with the χ-A^{'} coupling α_{D}≤0.1 for masses 0.001≲m_{χ}≲0.1 GeV and 3m_{χ}≤m_{A^{'}}.

Abstract
Abstract
Patient with complex congenital heart disease: situs inversus with dextrocardia and transposition of the great vessels (D–TGA), right aortic arch and inferior cava agenesis with azygos continuation; at 4 months Mustard atrial switch (intratrial baffle for redirection of the systemic venous circulation in the left subpulmonary left ventricle and of the pulmonary venous circulation in the right subaortic systemic ventricle). At 22 years, 1st pregnancy without complications, caesarean section, birth weight 2.2 kg. Two pregnancies spontaneously terminated in the firts trimester. At 29 years echocardiography: right systemic ventricle hypertrophic, dilated and slightly hypokinetic with tricuspid (systemic) valve with mild to moderate insufficiency; Mustard circuit normally functioning on the systemic side, mild stenosis of the pulmonary buffle (Gmax 6mmHg). At 33 years monochorionic biamniotic twins pregnancy; the risk linked to pregnancy for the patient on the basis of her heart disease was included in a WHO class III worsened by twinning. Because of the high probability of maternal and fetal complications related to the continuation of pregnancy, it was necessary to recommend a selective interruption of the pregnancy of the fetus affected by severe selective underdevelopment with signs of twin to twin transfusion at the 20th week of gestation. Maternal clinical and haemodynamic conditions have been stable during pregnancy. At the 24th week of gestation echocardiography: worsening of the systemic right function ventricle, moderate tricuspid insufficiency and increased gradients in the Mustard circuit (systemic Gmax 13mmHg and pulmonary venous Gmed 8mmHg). After the pregnancy team‘s discussion, a delivery plan was proposed to transfer the patient to a third level cardiac surgery center with experience in congenital heart disease adult between the 35th and 36th week. This was not possible because the patient at 32th week presented preterm labor with caesarean section without maternal and newborn complications (birth weight 1,650 kg). In the puerperium ehocardiography: hypertrophic, dilated and moderately hypokinetic systemic right ventricle with moderate tricuspid insufficiency; Mustard circuit: systemic baffle max gradient 16mmHg and pulmonary venous medium gradient 9mmHg. 7 years after this pregnancy at the last visit: stable clinical and echocardiographic situation with persistence of moderate dysfunction of the systemic right ventricle.

Abstract
A 12–year–old patient with paucisymptomatic SARS–COV2 infection in November 2020 with negative swab after 10 days. After 3 weeks access to pediatric emergency room for fever, maculo–papular rash on the trunk, conjunctivitis, nausea and abdominal pain: evidence of thrombocytopenia, increased CPK, LDH, AST and inflammation markers. She starts antibiotic therapy for suspected sepsis. After 24 hours asthenia, general illness, hypotension and tachycardia: echocardium with diffuse hypokinesia of the left ventricle (EF 35%); worsening of thrombocytopenia, D–Dimer, BNP and CPK increase, hyponatremia, troponin positivity, ATIII reduction; negative viral markers. On the basis of the most recent literature, the diagnosis of MIS–C is made, a post–infection SARS–COV2 multisystemic inflammatory syndrome. After discussion with the 3rd level SARS–COV2 Pediatric Center, the following therapy begins: iv diuretic, iv cortisone, sc heparin, iv immunoglobulins, Anakinra. For a progressive clinical worsening by cardiogenic shock with evolution to DIC, she is transferred by military plane to the pediatric intensive care of 3rd level SARS–COV2 Center. The patient is subjected to mechanical ventilation, therapy with inotropes (adrenaline and milrinone) and CRRT ultrafiltration in order to reduce the excessive levels of inflammatory mediators responsible for rapid multiorgan failure. After 4 days, haemodynamic parameters improvement (EF 50%); sartan and low dose diuretic have been started because of the presence of diastolic dysfunction. Discharge after 1 month of hospitalization with good clinical and haemodynamic stability. After 6 months from myocarditis onset with cardiogenic shock in MIS–C, cardiac MRI with evidence of EF 57% and small area of delayed enhancement on the anterior IVS with non–ischemic pattern, no longer present by imaging after 1 year by acute event. Currently the patient reports subjective well–being by the regular follow–up without arrhythmias by Holter monitoring. SARS–COV2 post–infection multisystemic inflammatory syndrome (MIS–C) represents a serious complication with possible myocardial involvement also following a paucysymptomatic infection as in the described case. What happened shows us that SARS–COV2 infection is still a devious clinical entity that needs close follow–up in the short and long term.

Abstract
BACKGROUND Melanism is more frequent in animals living in polluted areas on urban-industrial sites. Given that an increasing number of people are exposed to elevated air pollution levels, it is possible that environmental pollutants affect melanogenesis in human skin. Epidemiological studies have shown that exposure to traffic-related air pollutants such as diesel exhaust particles (DEP) is associated with more clinical signs of hyperpigmentation. However, mechanistic evidence linking DEP exposure to pigmentation has been elusive. OBJECTIVES To develop an ex vivo skin model to allow for repetitive topical application of relevant ambient DEP, and to provide proof of concept in humans. METHODS We measured skin pigmentation, melanin and pigmentation-associated gene expression, and evaluated oxidative stress. RESULTS Repetitive exposure of ex vivo skin to DEP at nontoxic concentrations increased skin pigmentation. This increase was visible to the naked eye, time dependent, and associated with an increase in melanin content and the transcription of genes involved in de novo melanin synthesis. Similarly, in healthy participants (n = 76), repetitive topical application of DEP at nontoxic concentrations increased skin pigmentation. DEP-induced pigmentation was mediated by an oxidative stress response. After the application of DEP, epidermal antioxidants were depleted, lipid peroxidation and oxidative DNA damage were enhanced, and in a vehicle-controlled, double-blind clinical study DEP-induced pigmentation was prevented by the topical application of an antioxidant mixture. CONCLUSIONS Similar to solar radiation, air pollutants cause skin tanning. As eumelanin is an antioxidant, it is proposed that this response serves to protect human skin against air pollution-induced oxidative stress.

Abstract
Abstract
Background
Many scientific societies highlight the importance of using e-Health and Telemedicine in everyday life. Are patients truly ready for this changing scenario in the cardiovascular field? Considering the current limited evidence on this topic we conducted a real-world data analysis in a rural area.
Purpose
The aim of the present study was to assess the attitude of a rural area population towards the use of m-Health and Telemedicine for the improvement of cardiovascular healthcare-organization and prevention.
Methods
An observational cross-sectional study, surveying 200 adult-subjects, with a multiple-choice questionnaire, was carried out by the authors during local health-fair events. We gathered self-reported demographics, digital skills, attitude towards telemedicine, and data regarding primordial, primary and secondary cardiac prevention, along with the strengths and the weaknesses of m-Health use.
Results
Of the 200 surveyed subjects, only 179 [90%] completed the poll. Overall, 40% [n=71] appeared to be aware of telemedicine and 86% [n=154] stated to be interested in its use for everyday health-organization and cardiovascular prevention. No significative difference emerged regarding basic and advanced technological skills after subject stratification based on the education level, residence or age, except for the oldest subjects (i.e. over 80 years of age) which resulted less technologically skilled [p<0.05]. According to the respondents, Personal Computer, smartphone and wearable devices were considered useful tools to improve treatment adherence [median value: 4 out of 5 - IQR 4–5], save time [median value: 4 out of 5 - IQR 4–5] and develop a tailored treatment approach [median value: 4 out of 5 - IQR 1–5]. Nonetheless, m-Health was unknown to half of the respondents; in fact, only 48% [n=86] of the interviewed subjects were aware of its existence and 35% [n=63] affirmed to use apps for a preventive purpose on a daily basis. Otherwise, the large majority of subjects reported to be interested in its use [75%, n=135]. Privacy issues emerged as a major concern for app users in the setting of primary and secondary prevention; while, only 19.4% of those using apps for primordial prevention showed the same degree of concern [p<0.05]. No other significative difference appeared among tested queries.
Conclusions
Our unselected population showed good technological skills and looked with favour at the advantages of telemedicine in everyday health-management because it provides reliable and feasible tools to improve cardiovascular healthcare in rural areas. However, awareness of its existence remains limited, underlining the need for more effective advertising policies. Although privacy and reliability issues currently make m-Health less feasible for primary and secondary prevention, m-Health has proved to be an excellent tool for primordial prevention.

Abstract
Abstract
Background
Health-related quality of life (HRQoL) of children is an important health outcome which has frequently been investigated regarding children's chronicle illnesses using parents proxy-reported HRQoL. Obesity is an increasingly frequent condition in children, for which the evidence about perceived quality of life is lacking. The aim of our study is to examine the concordance between child's and parents'- reported HRQoL according to children's weight status.
Methods
A cross-sectional study was conducted in 2019 among 128 children, aged 6-10, recruited in a primary school of Imola (Italy). Children were divided in Group1 (G1: normal-underweight) and Group2 (G2: overweight-obese) using the International Obesity Task Force cut points. HRQoL was assessed using the Italian version 4.0 of Paediatric Quality of Life (PedsQL) questionnaire. We obtained self-reported children's HRQoL total score and the parents' perceived children's HRQoL total score. Each score had two subscales: one for physical health and one for emotional, social and school functioning.
Results
In G1 there were 86 children and in G2 42. The correlation between the children's and parents' HRQoL scores is low in G1 (physical health: 0.24; emotional, social and school functioning: 0.15). Children in G2 and their and parents' perception of physical health are poorly correlated (r=-0.09) and those of emotional, social and school functioning are well correlated (r = 0.43).We observed that in case of discordant HRQoL results, parents usually overestimate their children's HRQoL.
Conclusions
Correlation between the children's and parents' HRQoL scores is low in G1. In G2 children's and parents' perception are concordant for emotional, social and school functioning and unrelated for physical health. It would be useful to investigate whether these results depend from lack of communication between parents and children or lack of parents' awareness of health-related problems with obesity.
Key messages
Parents and children have a discordant perception of physical health quality of life. Further studies should investigate the reasons why these results are discordant.

Abstract
We investigate an anomalous scattering phenomenon exhibited by a lossless system based on metasurfaces. Electromagnetic energy is neither reflected nor transmitted but stored within the system to be available again at a different time. We analytically derive the proper excitation conditions and verify the response of the system through a proper set of full-wave simulations, demonstrating the key role of the metasurface in enabling such a zero-scattering condition. The practical feasibility and the opportunities offered by the proposed metasurface-based system may open the door to the design of virtual absorbers with dynamic properties in energy absorbing, storing, and releasing.

Abstract
Extreme-ultraviolet-induced charge migration in biorelevant molecules is a fundamental step in the complex path leading to photodamage. In this work we propose a simple interpretation of the charge migration recently observed in an attosecond pump-probe experiment on the amino acid tryptophan. We find that the decay of the prominent low-frequency spectral structure with increasing pump-probe delay is due to a quantum beating between two geometrically distinct, almost degenerate charge oscillations. Quantum beating is ubiquitous in these systems, and at least on the few-to-tens of femtosecond time scales, it may dominate over decoherence the line intensities of time-resolved spectra. We also address the experimentally observed phase shift in the charge oscillations of two different amino acids, tryptophan and phenylalanine. Our results indicate that a beyond mean-field treatment of the electron dynamics is necessary to reproduce the correct behavior.

Abstract
yambo is an open source project aimed at studying excited state properties of condensed matter systems from first principles using many-body methods. As input, yambo requires ground state electronic structure data as computed by density functional theory codes such as Quantum ESPRESSO and Abinit. yambo's capabilities include the calculation of linear response quantities (both independent-particle and including electron-hole interactions), quasi-particle corrections based on the GW formalism, optical absorption, and other spectroscopic quantities. Here we describe recent developments ranging from the inclusion of important but oft-neglected physical effects such as electron-phonon interactions to the implementation of a real-time propagation scheme for simulating linear and non-linear optical properties. Improvements to numerical algorithms and the user interface are outlined. Particular emphasis is given to the new and efficient parallel structure that makes it possible to exploit modern high performance computing architectures. Finally, we demonstrate the possibility to automate workflows by interfacing with the yambopy and AiiDA software tools.

Abstract
Fricke gel radiochemical sensors based on various matrices have been studied for decades as 3D dosimeters for radiotherapy. Despite their many appealing features, progressive aging and blurring of the signal have prevented the widespread use of these dosimeters, so far. We have addressed these shortcomings and hereby present our development of a Fricke gel based on a chemically cross-linked PVA matrix. We investigated the influence of several parameters of the polymeric matrix on sensitivity, diffusion coefficient and spontaneous oxidation of the proposed gel dosimeter. Based on these findings, we optimized the gel compositions. Our new gel formulation combines transparency, high sensitivity and simple production method, typical of gels based on natural polymers, with low diffusion coefficient and slow spontaneous oxidation typical of PVA gels made by freezing-thawing.

Abstract
Twenty-five patients treated with debulking surgery and chemotherapy for ovarian cancer were prospectively studied to evaluate the efficacy of radioimmunoscintigraphy (RIS) in detecting residual tumor before second-look surgery. RIS was performed with the monoclonal antibody OC125 F(ab')2 labelled with 1-131 without knowledge of clinical data and compared with subsequent surgical results. Second look showed tumor persistence in 12 patients, mostly characterized by small lesions. The overall diagnostic sensitivity of RIS was 50% and the specificity was 85%. In particular, RIS showed better sensitivity for pelvic tumor localizations than for abdominal sites (73% vs 33%); this was due to the inability of RIS to detect upper abdominal lesions. Therefore, our conclusion is that, at present, RIS cannot substitute surgical second-look in the management of ovarian cancer, however, considering that also ultrasonography, computer tomography and magnetic resonance are not always able to give definite diagnostic evidence in the follow-up of ovarian carcinoma, RIS could be added to these procedures to balance the limitations of each method. In this regard, the best application of RIS could be in the follow-up of patients with marker elevation without clinical evidence of disease, especially in the case of pelvic fibrosis or adhesions due to previous therapy, where the other non-invasive tools can give doubtful diagnostic results.

Abstract
The present paper describes the case of a patient who developed a B-cell chronic lymphocytic leukemia (B-CLL) 15 months after the diagnosis of polycythemia vera, which had been treated only with phlebotomies. In spite of lymphocytosis and the clinical signs and symptoms of leukemia, the patient exhibited at the same time presumptive elements of polycythemia (high LAP index levels, a high number of neutrophils). Cytogenetic investigations, carried out after the appearance of B-CLL, revealed the presence of an unusual abnormality (18 p+) both in bone marrow not stimulated by mitogens and in PWM-stimulated circulating lymphocytes. This case, which is the ninth of its kind described in the literature, offers some interesting observations about the association between myeloproliferative and lymphoproliferative syndromes.

Abstract
The modifications in the concentration of circulating myoglobin have been studied by means of a radioimmunoassay in 15 cancer patients undergoing polychemotherapy including adriamycin. In 8 patients significant increases in myoglobin levels were found after injection of low doses of the drug (25-50 mg/m2). Moreover, a disturbance of the normal biorhythm of the protein was evident in 12 patients. Creatine kinase-MB was evaluated by means of a radioimmunoassay, but there was no relation between an increase in the isoenzyme and an increase in myoglobin. No ECG modifications were detected. These data indicate that the measurement of myoglobin may offer an indication of myocardial or skeletal muscle damage caused by adriamycin.

Abstract
The early-stage density oscillations of the electronic charge in molecules irradiated by an attosecond XUV pulse takes place on femto- or subfemtosecond time scales. This ultrafast charge migration process is a central topic in attoscience because it dictates the relaxation pathways of the molecular structure. A predictive quantum theory of ultrafast charge migration should incorporate the atomistic details of the molecule, electronic correlations, and the multitude of ionization channels activated by the broad-bandwidth XUV pulse. We propose a first-principles nonequilibrium Green's function method fulfilling all three requirements and apply it to a recent experiment on the photoexcited phenylalanine amino acid. Our results show that dynamical correlations are necessary for a quantitative overall agreement with the experimental data. In particular, we are able to capture the transient oscillations at frequencies 0.15 and 0.30 PHz in the hole density of the amine group as well as their suppression and the concomitant development of a new oscillation at frequency 0.25 PHz after ∼14 fs.

Abstract
The ability to imagine future events (episodic future thinking-EFT) emerges in preschoolers and further improves during middle childhood and adolescence. In the present study, we focused on the possible cognitive factors that affect EFT and its development. We assessed the ability to mentally project forward in time of a large cohort of 135 6- to 11-year-old children through a task with minimal narrative demands (the Picture Book Trip task adapted from Atance and Meltzoff in Cogn Dev 20(3):341-361. doi:10.1016/j.cogdev.2005.05.001, 2005) in order to avoid potential linguistic effects on children's performance. The results showed that this task can be used to assess the development of EFT at least until the age of 8. Furthermore, EFT scores correlated with measures of phonological short-term and verbal working memory. These results support the possibility that cognitive factors such as working memory play a key role in EFT.

Abstract
This brief report is a partial replication of the study by Jackson and Atance (J Dev Disabil 14:40-45, 2008) assessing nonverbal Self-based and Mechanical-based future thinking (FT) in children with Autism Spectrum Disorder (ASD). In a first step, these tasks were administered to 30 children with ASD. The two Self-based tasks were then modified as a verbal component could not be completely ruled out. Consequently, 77 children with ASD and 77 children with typical development received the modified Self-based FT tasks and the Mechanical-based FT tasks. We partially replicated the previous findings. Participants with ASD had impaired FT in both kinds of tasks and both groups performed better on tasks assessing Mechanical-based FT than Self-based FT. These results suggest that impairments of FT in ASD are not limited to Self-Projection.

Abstract
INTRODUCTION Recent automated hematology analyzers (HAs) can identify and report nucleated red blood cells (NRBC) count as a separate population out of white blood cells (WBC). The aim of this study was to investigate the analytical performances of NRBC enumeration on five top of the range HAs. METHODS We evaluated the within-run and between-day precision, limit of blank (LoB), limit of detection (LoD), and limit of quantitation (LoQ) of XE-2100 and XN-module (Sysmex), ADVIA 2120i (Siemens), BC-6800 (Mindray), and UniCel DxH 800 (Beckman Coulter). Automated NRBC counts were also compared with optical microscopy (OM). RESULTS The limits of detection for NRBC of the BC-6800, XN-module, XE-2100, UniCel DxH 800, and ADVIA 2120i are 0.035×109 /L, 0.019×109 /L, 0.067×109 /L, 0.038×109 /L, and 0.167×109 /L, respectively. Our data indicated excellent performance in terms of precision. The agreement with OM was excellent for BC-6800, XN-module, and XE-2100 (Bias 0.023, 0.019, and 0.033×109 /L, respectively). ADVIA 2120i displayed a significant constant error and UniCel DxH 800 both proportional and small constant error. CONCLUSION Regards to NRBC counting, the performances shown by BC-6800, XN-module, and XE-2100 are excellent also a low count, ADVIA 2120i and UniCel DxH 800 need to be improved.

Abstract
BACKGROUND The incidence of wound infections associated with instrumented spine surgery ranges from 2 to 20%. These complications may lead to poor outcomes. Knowing the risk factors associated with surgical site infections (SSI) after utilizing spinal implants is essential to avoid these complications, including hardware removal. METHODS We reviewed retrospectively 550 patients who underwent spinal fusion surgery from 2011 to 2015; 16 developed SSI after spinal instrumentation. The diagnosis of SSI was established based on positive wound swab or blood cultures, and various clinical, laboratory, and radiological findings. Additional preoperative and intraoperative risk factors were analyzed. RESULTS The incidence of SSI after spinal instrumentation surgery was 2.9%. Obesity was a statistically significant parameter (P = 0.013) that contributed to SSI along with the alcoholism and/or drug abuse (P = 0.034); use of a Foley catheter nearly reached significance levels. CONCLUSIONS There is an increased risk of SSI in patients who are obese or use drugs and/or alcohol. Clear preoperative identification of these risk factors prior to implanting spinal instrumentation should help prevent SSI in the future.

Abstract
IntroductionReactivity to acute psychosocial stress in the framework of a physiological multidimensional pattern affects several individual-level systems that include genetic factors and features related to personality development. The 5-HTTLPR genotype has been implicated in the modulation of susceptibility to environmental stimuli.ObjectivesIn the present study, 91 healthy young women were investigated (i) for their reactivity to a standardized psychosocial laboratory stressor (TSST), as measured by changes in salivary cortisol; (ii) in terms of 5-httlpr genotype and (iii) in terms of their personality profile according to the post-rationalist personal meaning organizations (PMOs), which are considered as adaptive modes of response to environmental stressors.MethodsParticipants were divided into three 5-HTTLPR genotype groups (s/s; s/l, and l/s). The quantitative and qualitative variables that may affect circulating cortisol were compared among the three groups. A multiple linear quantile regression analysis was then performed to evaluate the effect of the personality profile, as Outward/Inward PMO, and 5-HTTLPR genotype on the median level of cortisol, considered as dependent variable.ResultsComparison of the variables that may affect circulating cortisol no significant differences. Salivary cortisol changed significantly in the course of the TSST. Reactivity to stress was affected by personality profile and the 5-HTTLPR genotype and also by body mass index and age.ConclusionsThe present data suggest that the psychosocial stress response is a multidimensional physiological event that is affected by a variety of factors as diverse as 5-HTTLPR genotype, personality profile, BMI, and age.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
BACKGROUND Increasing evidence suggests photoprotection by oral supplementation with β-carotene and lycopene. OBJECTIVES To examine the capacity of lycopene-rich tomato nutrient complex (TNC) and lutein, to protect against ultraviolet (UV)A/B and UVA1 radiation at a molecular level. METHODS In a placebo-controlled, double-blinded, randomized, crossover study two active treatments containing either TNC or lutein were assessed for their capacity to decrease the expression of UVA1 the radiation-inducible genes HO1, ICAM1 and MMP1. Sixty-five healthy volunteers were allocated to four treatment groups and subjected to a 2-week washout phase, followed by two 12-week treatment phases separated by another 2 weeks of washout. Volunteers started either with active treatment and were then switched to placebo, or vice versa. At the beginning and at the end of each treatment phase skin was irradiated and 24 h later biopsies were taken from untreated, UVA/B- and UVA1-irradiated skin for subsequent reverse transcriptase polymerase chain reaction analysis of gene expression. Moreover, blood samples were taken after the washout and the treatment phases for assessment of carotenoids. RESULTS TNC completely inhibited UVA1- and UVA/B-induced upregulation of heme-oxygenase 1, intercellular adhesion molecule 1 and matrix metallopeptidase 1 mRNA, no matter the sequence (anova, P < 0·05). In contrast, lutein provided complete protection if it was taken in the first period but showed significantly smaller effects in the second sequence compared with TNC. CONCLUSIONS Assuming the role of these genes as indicators of oxidative stress, photodermatoses and photoageing, these results might indicate that TNC and lutein could protect against solar radiation-induced health damage.

Abstract
Results from several studies suggest that the process of language acquisition may be altered in patients suffering from Duchenne Muscular Dystrophy. In this study, a group of 8 male participants with Duchenne Muscular Dystrophy ( M age = 16 yr., SD = 4.7) underwent an extensive neuropsychological and language assessment. They also performed a discourse production task. Results showed mild mental retardation associated with a specific deficit in Verbal rather than Performance IQ. At the linguistic assessment, 7 of 8 participants showed moderate to severe difficulties on oral language processing with particularly impaired morphosyntactic competence.

Abstract
OBJECTIVE The aim of this study was to evaluate the accuracy of unenhanced whole-body MRI, including whole-body Diffusion Weighted Imaging (DWI), used as a diagnostic modality to detect pathologic lymph nodes and skeletal metastases in patients with prostate cancer (PCa) undergoing restaging after primary treatment. PATIENTS AND METHODS 152 male patients with biochemical recurrence after radical prostatectomy (RP) or external beam radiation therapy (EBRT) underwent MRI at a 1.5 Tesla magnet with whole spinal sagittal T2-weighted, sagittal T1-weighted, sagittal STIR images, axial T1 and T2-weighted and STIR images of the pelvis and whole-body. 18Fcholine-PET/CT exam was used as the reference standard. RESULTS MRI protocol including whole-body combined T1-weighted+T2-weighted+STIR+DWI showed a sensitivity (Se) of 99%, a specificity (Spe) of 98%, a positive predictive value (PPV) of 98%, a negative predictive value (NPV) of 96%, an accuracy of 98% and an area under the receiver operating characteristic curve (AUC) of 0.971 for identification of bone metastatic lesion. The same protocol, displayed a Se of 98%, a Spe of 99%, a PPV of 97%, a NPV of 98%, an accuracy of 98 % and an AUC of 0.960 in the detection of pathologic lymph nodes. CONCLUSIONS Unenhanced whole-body MRI, including whole-body-DWI, is an accurate and cost-effective diagnostic tool which is able to detect lymph node involvement and bone metastases in patients with biochemically recurrent PCa after RP or EBRT. Thanks to its lack of ionizing radiation, excellent soft tissue contrast, high spatial resolution, no need of contrast agent, high Se and Spe, it could play a role in the restaging procedure of such patients.

Abstract
New insights into the reaction pathways of different potassium/magnesium amide-hydride based systems are discussed. In situ SR-PXD experiments were for the first time performed in order to reveal the evolution of the phases connected with the hydrogen releasing processes. Evidence of a new K-N-H intermediate is shown and discussed with particular focus on structural modification. Based on these results, a new reaction mechanism of amide-hydride anionic exchange is proposed.

Abstract
Manipulating and controlling the optical energy flow inside random media is a research frontier of photonics and the basis of novel laser designs. Here, we show that a metamaterial consisting of randomly dispersed graphene nanoflakes embedded within an optically pumped gain medium (rhodamine 6G) can operate as a cavity-free laser thanks to its extraordinarily low threshold for saturable absorption. The emitted light is self-organized into a well-determined spatial pattern, which depends on the graphene flake density and can be externally controlled through the optical pump. We provide different examples of tunable laser operation ranging from stable single-mode to chaoticlike behavior. Our metamaterial design holds great potential for the optical control of light amplification, as well as for the development of single-mode beam-engineered cavity-free lasers.

Abstract
The renormalization of electronic eigenenergies due to electron-phonon coupling (temperature dependence and zero-point motion effect) is sizable in many materials with light atoms. This effect, often neglected in ab initio calculations, can be computed using the perturbation-based Allen-Heine-Cardona theory in the adiabatic or non-adiabatic harmonic approximation. After a short description of the recent progresses in this field and a brief overview of the theory, we focus on the issue of phonon wavevector sampling convergence, until now poorly understood. Indeed, the renormalization is obtained numerically through a slowly converging q-point integration. For non-zero Born effective charges, we show that a divergence appears in the electron-phonon matrix elements at q → Γ, leading to a divergence of the adiabatic renormalization at band extrema. This problem is exacerbated by the slow convergence of Born effective charges with electronic wavevector sampling, which leaves residual Born effective charges in ab initio calculations on materials that are physically devoid of such charges. Here, we propose a solution that improves this convergence. However, for materials where Born effective charges are physically non-zero, the divergence of the renormalization indicates a breakdown of the adiabatic harmonic approximation, which we assess here by switching to the non-adiabatic harmonic approximation. Also, we study the convergence behavior of the renormalization and develop reliable extrapolation schemes to obtain the converged results. Finally, the adiabatic and non-adiabatic theories, with corrections for the slow Born effective charge convergence problem (and the associated divergence) are applied to the study of five semiconductors and insulators: α-AlN, β-AlN, BN, diamond, and silicon. For these five materials, we present the zero-point renormalization, temperature dependence, phonon-induced lifetime broadening, and the renormalized electronic band structure.

Abstract
INTRODUCTION Several studies have shown that Hispanic patients generally experience a worse renal prognosis than non-Hispanic white patients with lupus. To date, there is no report on American College of Rheumatology (ACR) renal response criteria (ACR-RRC) in patients from Latin America. OBJECTIVE To evaluate treatment response in patients with proliferative and membranous lupus nephritis (LN) according to ACR-RRC. METHODS A retrospective study (2001-2011) was performed in our hospital and the data collected included clinical information, renal assessment and immunological parameters. Details related to treatment received during induction and maintenance therapy were also recorded. RESULTS The study included forty-three Latin American patients (37 women) from Argentina. Mean follow-up was 54 months. The regimen used for induction therapy included intravenous cyclophosphamide (IV-CYC) for six months in 36 patients and only seven received mycophenolate mofetil (MMF) given twice daily for a total dose of 2.5 ± 0.5 grams a day. For the maintenance period, six patients continued with quarterly IV-CYC, 20 patients received MMF (1.5 ± 0.5 grams a day) and 17 patients received azathioprine (AZA) 1.5 - 2 mg/kg/day. ACR-RRC observed after induction therapy was complete response in 19%, partial response in 9%, improvement in 42%, unchanged in 14%, and 16% had deterioration despite treatment. ACR-RRC observed after maintenance therapy was complete response in 30%, partial response in 23%, improvement in 19%, unchanged in 16%, and 12% had deterioration. Relapse was observed in 11 patients (25%). Ten out of 11 cases (91%) who relapsed did not achieve a complete response at the end of the induction therapy. CONCLUSION In Latin American patients from Argentina, only 19% could achieve a complete response after induction therapy and 30% achieved a complete response after maintenance therapy. Failing to obtain a complete response after induction therapy was related to an increased risk of relapse during long-term follow-up in our study.

Abstract
OBJECTIVE The aim of this study was to evaluate the clinical usefulness of computed tomography colonography (CTC) in the preoperative staging in patients with abdominal pain for occlusive colorectal cancer (CRC) and to compare the results of CTC with the surgical ones. PATIENTS AND METHODS 127 patients with abdominal pain, iron deficiency anemia and occlusive CRC underwent a CTC examination in prone position without intravenous contrast agent and in prone position after administration of intravenous contrast medium. All the patients underwent surgery after CTC. Two radiologists with different experience analyzed the images first independently and then by consensus. They evaluated the location of the lesion, the depth of the invasion of the colon-rectal wall (T stage), lymph node involvement (N stage) and the presence or absence of distant metastasis (M stage). CTC findings were correlated with surgical outcomes. RESULTS The overall accuracy values for tumour localization according to consensus reading of CTC examinations in comparison to surgical results were 100% (K = 1, p = 0.0001). The overall accuracy values of agreement for T staging of reader 1, reader 2 and consensus reading of CTC examinations in comparison to surgical results were respectively 95.5% (K = 0.876, p = 0.0035), 93.3% (K = 0.858, p = 0.0037) and 97.7% (K = 0.926, p = 0.0014) for ≤ T2; 91.3% (K = 0.839, p = 0.0027), 88.3% (K = 0.817, p = 0.0031), and 92.9% (K = 0.894, p = 0.0025) for T3; 89.6% (K = 0.825, p = 0.0037), 86.2% (K = 0.837, p = 0.0032) and 89.6% (K = 0.821, p = 0.0023) for T4. The overall accuracy values for N staging for reader 1, reader 2 and consensus reading was 90.2% (K = 0.865, p = 0.0029). The overall accuracy values for M staging of reader 1, reader 2 and consensus reading was 92% (K = 0.875, p = 0.0019). CONCLUSIONS CTC with is a very useful tool for accurate pre-treatment staging and localization of occlusive CRC.

Abstract
OBJECTIVE The aim of this study is to prove if dynamic HASTE (half-Fourier acquisition single-shot turbo spin-echo) sequences can be used in the diagnosis of internal derangement disorders of temporomandibular joint (TMJ) as an alternative to static proton density (PD) weighted/turbo spin echo (TSE) T2-weighted sequences which are considered up to now as the gold standard in the evaluation of TMJ disorders (TMDs). PATIENTS AND METHODS 194 patients for a total of 388 TMJs were examined with a 1.5 Tesla field strength superconducting magnet. Sagittal static PD-weighted/TSE T2-weighted and dynamic HASTE sequences have been used. Three experts in the field of oral radiology (specialist A, B and C) independently and blinded to clinical symptoms and any treatment, assessed the articular disc position in each TMJ (rated as normal or disc displacement with reduction or disc displacement without reduction). The agreement between static and dynamic images and between the three different specialists in the assessment of the articular disc position was evaluated using kappa statistic. RESULTS The agreement between static and dynamic images is: for specialist A, K = 0.862; for specialist B, K = 0.870 and for specialist C, K = 0.862. CONCLUSIONS Since there is no complete agreement between these two MR techniques, dynamic sequences can not be used as a reliable alternative to static sequences in the evaluation of internal derangement disorders of TMJ.

Abstract
Abstract
From a purely enthalpic standpoint, the ß-CD hydration, as studied by semiempirical calculations, appears improbable, in contrast to experiment. For the spontaneous hydration process, a compensation mechanism, connected with substrate stabilization and/or entropy increase, is suggested on the basis of simple thermodynamic considerations. The analysis is done on the basis of a single parameter Ew (> 0), which represents the energy needed to transfer a mole of water from the liquid to the ß-CD absorbed phase.
The model, although simple, allows predictions largely consistent with the experimental results, while suggesting possible interpretations.

Abstract
Mixtures xSrCO3 (1 - x)BaCO3 TiO2 (0 < x < 1) have been mechanically activated by high energy milling in order to promote the formation of mixed (Sr,Ba) carbonate that decomposes, in a single stage, at temperatures generally lower than for the corresponding physical mixtures. By annealing such milled mixtures at high temperatures (≈ 1000 °C), cubic solid solutions SrxBa(1-x)TiO3 are obtained (except at x = 0.1 where a tetragonal solid solution forms) whose lattice parameters decrease linearly with x. The enthalpy of solid solution formation changes with composition showing higher values in the x range between x = 0.2 and 0.5 where the reaction has been demonstrated to occur via the formation of Ba2TiO4. By contrast, the enthalpy values decrease for x > 0.5.

Abstract
It is known from the literature that a slight distortion of the ideal cubic cell is present in the NiO structure. This work shows that such a distortion can be accurately evaluated by means of a refinement of the structural and profile parameters of X-ray powder diffraction data. Moreover, since only small amounts of products are sometimes at disposal to perform structural characterizations, it was thought useful to extend the refinement procedure to X-ray data collected on NiO samples of much lower mass (15-60 mg) than those usually utilized in X-ray diffractometric studies. The results obtained show that reliable structural parameters can be obtained from low mass samples too
