Abstract
OBJECTIVES Systemic sclerosis (SSc) is a devastating autoimmune disease characterized by fibrosis and obliterative vasculopathy affecting the skin and visceral organs. While the processes mediating excessive extracellular matrix (EM) deposition and fibroblast proliferation are clear, the exact link between autoimmunity and fibrosis remains elusive. Th17 cells have been proposed as critical drivers of profibrotic inflammation during SSc, but little is known about the immune components supporting their pathogenic role. METHODS Dendritic cells (DCs) activate and shape T cell differentiation by producing polarizing cytokines. Hence, we investigated the cytokine responses of monocyte-derived DCs (Mo-DCs) from patients with limited cutaneous SSc (lcSSc), diffuse cutaneous SSc (dcSSc), and healthy controls (HC) after stimulation with toll-like receptor (TLR) agonists. Also, using co-culture assays, we analyzed T cell subpopulations after contact with autologous TLR-activated Mo-DCs. RESULTS In general, we observed an increased production of Th17 related cytokines like IL-1β, IL-17F, IL-21, IL-22 by SSc compared with HC Mo-DCs, with variations between lcSSc vs. dcSSc and early- vs. late-stage subgroups. Noticeably, we found a significant increment in IL-33 production by Mo-DCs in all SSc cases regardless of their clinical phenotype. Strikingly, T cells displayed Th2, Th17, and dual Th2/Th17 phenotypes after exposure to autologous TLR-stimulated Mo-DCs from SSc patients but not HC. These changes were pronounced in individuals with early-stage dcSSc and less significant in the late-stage lcSSc subgroup. CONCLUSIONS Our findings suggest that functional alterations of DCs subsidize the immune mechanisms favoring the aberrant T cell polarization and profibrotic inflammation behind the clinical SSc heterogeneity.

Abstract
Non-biodegradable metals such as mercury accumulate in living organisms during
life (bioaccumulation) and also within trophic webs (biomagnification) and may
reach high concentrations in humans. The contamination of humans by mercury in
drinking water and food may be common, in particular in riverside communities
that have a diet rich in fish. In vitro studies of human cell
lines exposed to the cytotoxic and mutagenic effects of methylmercury have shown
that prolactin has potential cytoprotective properties and may act as a
co-mitogenic factor and inhibitor of apoptosis. The present in
vivo study investigated the protective potential of prolactin
against the toxic effects of methylmercury in the mammal Mus
musculus. Histological and biochemical analyses, together with
biomarker of genotoxicity, were used to verify the protective potential of
prolactin in mice exposed to methylmercury. The reduction in kidney and liver
tissue damage was not significant. However, results of biochemical and genotoxic
analyses were excellent. After prolactin treatment, a significant reduction was
observed in biochemical parameters and mutagenic effects of methylmercury. The
study results therefore indicated that prolactin has protective effects against
the toxicity of methylmercury and allowed us to suggest the continuation of
research to propose prolactin in the future, as an alternative to prevent the
damage caused by mercury, especially in populations that are more exposed.

Abstract
Certification of quantum nonlocality plays a central role in practical applications like device-independent quantum cryptography and random number generation protocols. These applications entail the challenging problem of certifying quantum nonlocality, something that is hard to achieve when the target quantum state is only weakly entangled, or when the source of errors is high, e.g. when photons propagate through the atmosphere or a long optical fiber. Here we introduce a technique to find a Bell inequality with the largest possible gap between the quantum prediction and the classical local hidden variable limit for a given set of measurement frequencies. Our method represents an efficient strategy to certify quantum nonlocal correlations from experimental data without requiring extra measurements, in the sense that there is no Bell inequality with a larger gap than the one provided. Furthermore, we also reduce the photodetector efficiency required to close the detection loophole. We illustrate our technique by improving the detection of quantum nonlocality from experimental data obtained with weakly entangled photons.

Abstract
Systemic Lupus Erythematosus (SLE) is an autoimmune inflammatory disorder for which Major Histocompatibility Complex (MHC) genes are well identified as risk factors. SLE patients present different clinical phenotypes, which are partly explained by admixture patterns variation among Mexicans. Population genetic has insight into the high genetic variability of Mexicans, mainly described through HLA gene studies with anthropological and biomedical importance. A prospective, case-control study was performed. In this study, we recruited 146 SLE patients, and 234 healthy individuals were included as a control group; both groups were admixed Mexicans from Mexico City. The HLA typing methods were based on Next Generation Sequencing and Sequence-Based Typing (SBT). The data analysis was performed with population genetic programs and statistical packages. The admixture estimations based on HLA-B and -DRB1 revealed that SLE patients have a higher Southwestern European ancestry proportion (48 ± 8%) than healthy individuals (30 ± 7%). In contrast, Mexican Native American components are diminished in SLE patients (44 ± 1%) and augmented in Healthy individuals (63 ± 4%). HLA alleles and haplotypes' frequency analysis found variants previously described in SLE patients from Mexico City. Moreover, a conserved extended haplotype that confers risk to develop SLE was found, the HLA-A∗29:02∼C∗16:01∼B∗44:03∼DRB1∗07:01∼DQB1∗02:02, pC = 0.02, OR = 1.41. Consistent with the admixture estimations, the origin of all risk alleles and haplotypes found in this study are European, while the protection alleles are Mexican Native American. The analysis of genetic distances supported that the SLE patient group is closer to the Southwestern European parental populace and farthest from Mexican Native Americans than healthy individuals. Heterogeneity of genetic admixture determines SLE susceptibility and protection in Mexicans. HLA sequencing is helpful to determine susceptibility alleles and haplotypes restricted to some populations.

Abstract
Introduction Discontinuity in child and adolescent mental health services (CAMHS) and adult mental health services (AMHS) constitutes an important challenge in mental health care. In the last decade, efforts have been made to better define the transitioning population and build consensual models for CAMHS-AMHS’ transition. Objectives We aim to present our protocol and transition consultation results on the scope of published literature. Methods Description of protocol and casuistic of 18 months’ transition consultation at Centro Hospitalar Barreiro-Montijo. The literature found on PubMed was published from 2008 to 2020 and was reviewed using the keywords: transition, CAMHS, AMHS, adolescent, mental health service, young people. Articles with full text available written in English and French were selected. The included clinical studies focused on populations with neurodevelopmental disorders, psychotic disorders, non-suicidal self-harm and suicidal attempts. Results Forty-four articles were included, published from 2008 to 2020. 4 articles were excluded on basis of language and diagnosis criteria (eating disorders). Twelve were reviews, 24 were clinical studies and 4 were opinion articles. There are cultural and referral issues that explain the loss of patients in this transition gap. Individuals with history of severe mental illness were more frequently referred than those with neurodevelopmental disorders. Optimal transition is defined as adequate transition planning with a flexible age cut-off and continuity of care following transition. Conclusions For the vast majority of service users, transition from CAMHS to AMHS is poorly planned, executed and experienced. Improving transition models is essential to the patients autonomy’ promotion and a stronger adult mental health.

Abstract
BLK and BANK1 in primary Sjögren's syndrome (pSS) have scarcely been evaluated and the results are inconclusive. The aim of our study was to determine whether single nucleotide variants (SNVs) located within BLK or BANK1 are associated with susceptibility, clinical and serological features, and smoking in pSS. BLK rs13277113A/G, BANK1 rs10516487G/A and rs3733197G/A were genotyped in 203 cases and 424 controls using a TaqMan® SNP genotyping assay. The BLK rs13277113A allele showed association with pSS under the allelic (OR 1.35, p = 0.02), and recessive (OR 1.83, p = 0.003) model, while, BANK1 rs3733197G/A showed association under the dominant model (OR 2.90, p = 0.043). Interactions between BANK1 and BLK genotypes also showed association (OR 2.36, p < 0.0001). In addition, BLK rs13277113A/G was associated with protection against arthritis and BANK1 rs10516487G/A with both arthritis and keratoconjunctivitis sicca, meanwhile, BANK1 rs3733197G/A was associated with smoking in patients with pSS. This is the first study to describe an association between BLK and susceptibility to pSS in a Latin-American population. Our data also shows a first evidence of association between interactions of BLK and BANK1 in pSS, and association of BLK and BANK1with arthritis, keratoconjunctivitis sicca and smoking in patients with pSS.

Abstract
The mechanisms that drive systemic lupus erythematosus (SLE) patients to achieve remission are unknown; one possible explanation might be T cell exhaustion. The aim of the present study was to measure CD4+ and CD8+ T cell exhaustion in SLE patients in prolonged remission (PR-SLE) and compared them with patients with active SLE (Act-SLE) and healthy subjects. We included 15 PR-SLE patients, 15 Act-SLE and 29 healthy subjects. T cell exhaustion was determined by flow cytometry according to the expression of programmed cell death 1 (PD)-1, T cell immunoglobulin and mucin 3 (Tim-3), natural killer cell receptor (2B4), eomesodermin (EOMES) and T-box transcription factor TBX21 (T-bet) in CD4+ and CD8+ T cells. Dimensionality reduction using the T-distributed stochastic neighbor-embedding algorithm and clustering analysis was used for the identification of relevant populations. Percentages of CD3+ , CD4+ and CD8+ T cells were similar among groups. We identified five subpopulations of CD8+ and seven of CD4+ cells. The CD4+ T-bet+ CD45RO+ cells identified in the unsupervised analysis were significantly increased in PR-SLE versus Act-SLE [median = 0·20, interquartile range (IQR) = 1·74-30·50 versus 1·68, IQR = 0·4-2·83; P < 0·01]. CD4+ EOMES+ cells were also increased in PR-SLE versus Act-SLE (5·24, IQR = 3·38-14·70 versus 1·39, IQR = 0·48-2·87; P < 0·001). CD8+ EOMES+ cells were increased in PR-SLE versus Act-SLE (37·6, IQR = 24·9-53·2 versus 8·13, IQR = 2·33-20·5; P < 0·001). Exhausted and activated T cells presented an increased frequency of PD-1, CD57 and EOMES in SLE patients versus healthy subjects. Some subpopulations of T cells expressing markers associated with exhaustion are increased in patients in remission, supporting T cell exhaustion as a tolerance mechanism in SLE. Exhaustion of specific populations of T cells might represent a potential therapeutic tool that will contribute to the goal of achieving sustained remission in these patients.

Abstract
Entangled photons produced by spontaneous parametric down-conversion have been of paramount importance for our current understanding of quantum mechanics and advances in quantum information. In this process, the quantum correlations of the down-converted photons are governed by the optical properties of the pump beam illuminating the nonlinear crystal. Extensively, the pump beam has been modeled by either coherent beams or by the well-known Gaussian-Schell model, which leads to the natural conclusion that a high degree of optical coherence is required for the generation of highly entangled states. Here, we show that when a novel class of partially coherent Gaussian pump beams is considered, a distinct type of quantum state can be generated for which the amount of entanglement increases inversely with the degree of coherence of the pump beam. This leads to highly incoherent yet highly entangled multiphoton states, which should have interesting consequences for photonic quantum information science.

Abstract
An essential component of future quantum networks is an optical switch capable of dynamically routing single photons. Here we implement such a switch, based on a fiber-optical Sagnac interferometer design. The routing is implemented with a pair of fast electro-optical telecom phase modulators placed inside the Sagnac loop, such that each modulator acts on an orthogonal polarization component of the single photons, in order to yield polarization-independent capability that is crucial for several applications. We obtain an average extinction ratio of more than 19 dB between both outputs of the switch. Our experiment is built exclusively with commercial off-the-shelf components, thus allowing direct compatibility with current optical communication systems.

Abstract
Background Cytotoxic chemotherapy can cure advanced germ cell tumors. Nevertheless, cancer treatment may induce cellular senescence and accelerate molecular aging. The aging process implies an increase of cells expressing p16INK4a and changes in lymphocyte subpopulations. Our aim was to study the potential induction of premature immunosenescence in testicular cancer survivors (TCS) exposed to chemotherapy. Methods Case-control exploratory study of TCS treated with chemotherapy (≥3 BEP cycles, disease-free ≥3 months) compared with age matched healthy controls. Peripheral blood mononuclear cells were isolated, and lymphocyte subpopulations were analyzed by flow cytometry. CDKN2A/p16INK4a expression in T cells was measured using qPCR. The percentage of lymphocyte subpopulations and the CDKN2A/p16INK4a expression in TCS were compared with the control group using the Wilcoxon signed-rank test. Results We included 16 cases and 16 controls. The median age was 27 years (minimum 24, maximum 54) and the median time on surveillance was 26.5 months (minimum 3, maximum192). TCS had a lower percentage of total T cells and CD4+ T cells in total lymphocytes. Among the CD4+ T lymphocytes, TCS had less naïve CD4+ and increased memory CD4+ cells. Within the CD8+ T lymphocytes, TCS exhibited a decrease in the percentage of naïve cells and an increase in CD8 + CD45RA + CD57+ cells. TCS also exhibited decreased memory CD19+ B cells compared to the controls. The relative expression of CDKN2A/p16INK4a in T cells was increased in TCS (mean 1.54; 95% CI of the mean: 1.074–2.005; p = 0.048). Conclusion In this exploratory study, TCS showed increased expression of CDKN2A/p16INK4a and a lymphocyte phenotype that has been associated with immunosenescence. Further studies are warranted to define the clinical implications of these alterations in TCS.

Abstract
OBJECTIVES Lipid mediators derived from polyunsaturated fatty acids (FA), have been related to inflammation and immune response regulation. Herein we evaluated the intake and serum levels of ω-3 and ω-6 FA among patients with primary Sjögren's syndrome (pSS), and correlated with ocular/oral sicca symptoms, disease activity and a panel of chemokines/cytokines. METHODS We included 108 patients and 100 controls. Dietary information was obtained from a food questionnaire of one-day reminder and processed using a nutritional software. Among the SS group, we measured serum ω-3 (α-linolenic acid [α-LN], eicosapentaenoic acid [EPA], docosahexaenoic acid [DHA]) and ω-6 (linoleic acid [LA], arachidonic acid [AA]) by gas chromatography flame ionization. We scored the ESSDAI, ESPRI, Schirmer-I test and NSWSF. In a subsample, we assessed the OSDI, ophthalmologic staining scores and measured CXCL8, CXCL10, CCL2, IL-22 and IL-21 in saliva, and CXCL8, CXCL10, CCL2 and CXCL9 in tears by Luminometry. RESULTS ω-3 and ω-6 intake was lower in SS patients than controls, and did not correlate with serum levels. We found a negative correlation between α-LN and the OSDI and ESSDAI, as well as DHA and ESSDAI. In tears, AA positively correlated with CXCL9, whereas in saliva, α-LN, DHA and the ω3 sum negatively correlated with CCL2. We observed a negative correlation between the ω6 sum and IL-21. CONCLUSIONS pSS patients had deficient omega intake. Lower ocular symptoms, ESSDAI scores and salivary CCL2 correlated with higher ω-3 levels, possible suggesting a role in chronic inflammation. Further studies are warranted to deepen in the knowledge of this association.

Abstract
Abstract
Introduction
Ablation of atrial fibrillation (AF) by catheter is an effective therapy, particularly in cases of refractoriness to medical therapy. Pulmonary vein isolation (PVI) has a significative long-term recurrence rate of AF, but the recurrence factors after this procedure are poorly defined.
Purpose
To characterize the causes of AF recurrence after PVI and to evaluate complementary strategies that can optimize the therapeutic efficacy.
Methods
A single centre prospective study of patients (pts) with AF submitted consecutively to PVI since September 2004. The variables responsible for the recurrence of AF, the complementary strategies of optimization of AF ablation and the occurrence of other dysrhythmias were evaluated.
Results
A population of 521 pts were submitted to PVI as a primary strategy for AF treatment - 36.1% for paroxysmal AF, 32.5% for persistent AF <1 year, 14.5% persistent AF> 1 year.
Eighty-three pts needed to perform 2 ablations and 10 pts performed 3 ablations. The higher the number of AF ablations, the higher the incidence of atypical atrial flutter (2% in the 1st AF ablation, 17% in the 2nd and 44% after 3 ablations).
In the pts with recurrence of AF undergoing the 2nd ablation, it was verified that most of the pulmonary veins (PV) were not isolated, with an isolation rate of only 34.1% for the right inferior PV; 29.4% for superior PV right, 29.4% lower left VP, 28.2% upper left PV. In this group, in addition to a new PVI in the pts with re-conduction of PV, 45% performed complementary ablation strategies such as: ablation of the cavo-tricuspid isthmus (52.6%); ablation of the left atrium roof line (29%); mitral isthmus ablation line (26%); applications in the scar zone (26%); posterior atrial left line (8%), atrioventricular nodal reentrant atrioventricular ablation (5%), atrial tachycardia ablation (2.6%).
In the pts submitted to the 3rd ablation, again a low PV isolation rate was confirmed: only 44.4% for the both left PV and upper right PV, and 55.6% for the right lower VP. 33.3% also performed cavo-tricuspid isthmus ablation, 22.2% lower mitral isthmus isolation and 22.2% re-isolation of gaps in the roof or intracicritricial line.
Conclusion
This prospective study demonstrates a high rate of PV re-conduction after PVI and its role in AF recurrence. Therefore, the need for a more effective and definitive IVP technique is evident.

Abstract
INTRODUCTION Autoimmune thyroid disease (AITD) is the most common autoimmune disorder worldwide. Remarkably, it is commonly accompanied by other autoimmune diseases, such as rheumatoid arthritis (RA). The immunopathogenic mechanisms behind the coexistence of these disorders are still not completely understood. Immunogenetics influences the physiopathology of these diseases since ethnicity plays an essential role in the inheritance of susceptibility markers. METHODS High-resolution HLA class II typing was performed using a sequence-based method. RESULTS The allele frequency of HLA-DRB1∗04:04 and -DRB1∗03:01 were significantly increased in patients with AITD and RA compared to healthy individuals, pC = 0.021, OR = 2.4, 95%CI = 1.19-4.75 and pC = 0.009, OR = 3.4, 95%CI = 1.42-7.93, respectively. Remarkably, these patients have a combined risk given by susceptibility HLA-DRB1 alleles that contain the shared epitope, pC = 0.03, OR = 1.7, IC95% = 1.07-2.76, and a lack of protective alleles carrying aspartic acid70, pC = 0.009, OR = 0.5, IC95% = 0.32-0.84. DISCUSSION The results suggest that patients with AITD and RA have an immunogenetic mechanism that combines the susceptibility alleles associated with both diseases. Importantly, it seems to be linked mainly to the lack of protective alleles with aspartic acid in the position 70, along with the presence of susceptibility alleles that have the sequences QRRAA, QKRAA, and RRRAA at positions 70-74. CONCLUSION Patients with AITD and RA have a characteristic immunogenetic signature, which could be useful for determining multiple autoimmunities and assessing their relatives' risk of developing it.

Abstract
We report on a new technique for entanglement distillation of the bipartite continuous variable state of spatially correlated photons generated in the spontaneous parametric down-conversion process (SPDC), where tunable non-Gaussian operations are implemented and the post-processed entanglement is certified in real-time using a single-photon sensitive electron multiplying CCD (EMCCD) camera. The local operations are performed using non-Gaussian filters modulated into a programmable spatial light modulator and, by using the EMCCD camera for actively recording the probability distributions of the twin-photons, one has fine control of the Schmidt number of the distilled state. We show that even simple non-Gaussian filters can be finely tuned to a ∼67% net gain of the initial entanglement generated in the SPDC process.

Abstract
AIM To evaluate the stiffness of parotid and submandibular glands using elastography ultrasound and to correlate it with B-mode ultrasonographical, clinical and serological features, salivary profibrotic and inflammatory chemokines, and salivary gland fibrosis. METHODS We performed B-mode and elastography ultrasound of major salivary glands of 26 patients with primary Sjögren's syndrome. We registered the shear wave velocity (SWV) and correlated it with the morphologic ultrasonographic changes assessed by the Hocevar scale. We assessed the European League Against Rheumatism (EULAR) Sjögren's Syndrome Disease Activity Index (ESSDAI), EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI), non-stimulated whole salivary flow rate (NSWSF), C3 and C4 levels, anti-Ro/La antibodies, salivary inflammatory (C-X-C motif ligand 13 [CXCL13], CXCL10, CXCL8, C-C motif ligand 2 [CCL2], interleukin 10 [IL-10] and IL-6) and pro-fibrotic (CXCL14, CCL28, tumor necrosis factor-related apoptosis-inducing ligand and transforming growth factor β) chemokines and cytokines and evaluated the presence of fibrosis in the minor salivary gland. RESULTS Ninety-two percent of patients were women; mean age was 51.1 ± 11 years; median disease duration was 6.1 years; 92.3% had oral symptoms and 26.9% fibrosis. The median B-mode score was 22.2 points and the median SWV 2.5 m/s (τ = 0.53, P = 0.001). The SWV correlated with the NSWSF (τ = -0.53, P = 0.001), ESSDAI (τ = 0.31, P = 0.03), glandular ESDDAI domain (τ = 0.36, P = 0.02), C4 levels (τ = -0.32, P = 0.04), salivary CXCL13 (τ = 0.29, P = 0.03) and CXCL10 (τ = 0.30, P = 0.003), but not with age and fibrosis. CONCLUSION WV correlated with the B-mode ultrasound score, systemic and glandular activity and in a large degree with CXCL10, an inflammatory chemokine, but not with fibrosis. An increased SWV might represent chronic glandular inflammation rather than fibrotic changes in these patients.

Abstract
548 Background: Cytotoxic chemotherapy can cure patients with advanced germ cell tumors. Nevertheless, cancer treatment may induce cellular senescence and accelerate molecular aging. The aging process implies an increase of cells expressing p16INK4a and changes in lymphocyte subpopulations. Our aim was to study the potential induction of premature immunosenescence in testicular cancer patients exposed to chemotherapy. Methods: Case-control study of testicular cancer survivors (TCS) treated with chemotherapy (≥3 BEP cycles, disease-free ≥ 3 months) matched by age with healthy controls. Peripheral blood mononuclear cells were isolated, and lymphocyte subpopulations were analyzed by flow cytometry. p16INK4a expression was measured using real-time polymerase chain reaction, and the 2-ΔΔCt method was used for the p16INK4a expression analysis. Groups were compared with Mann-Whitney U test. Results are expressed as median (IQR) unless otherwise indicated. Results: We included 15 cases and 15 controls. Mean age 32.5 yo (24-54), mean time since last chemo 49.5 months (3-192). TCS had a lower percentage of CD3+ (62 (57-68) vs 72 (65-82) p = 0.026) and CD4+ (35 (27-41) vs 42 (38-53) p = 0.013) cells in total lymphocytes. TCS also had a lower % of naïve CD4+ (32 (15-44) vs 39 (32-55) p = 0.041), CD4+CD28+ (90 (85-97) vs 98 (95-99) p = 0.029) and CD8+ naïve (15 (8-26) vs 27 (22-42) p = 0.023) cells. TCS had an increased % of memory CD4+ (18 (13-26) vs 9 (6-11) p = 0.001) and memory CD19+ B cells (76 (62-88) vs 70 (64-79) p = 0.004). The relative expression of p16INK4a in CD3+ cells was higher in TCS compared to controls (1.29±0.36 vs 0.85±0.54; p = 0.035). Conclusions: TCS showed an increase in the expression of the aging biomarker p16INK4a and a lymphocyte phenotype associated with immunosenescence; characterized by a decrease in naïve cells, and concomitant increment of memory and CD28- cells. This phenomenon is believed to contribute to the development of an immune risk profile in the elderly, associated with an increased rate of infections and a diminished effect of vaccines. This is the first time this finding is reported in TCS. Further studies are warranted to define the clinical implications of this alteration.

Abstract
Several studies suggest an important role of Interleukin-27 in the development of atherosclerosis. The aim of this study was to establish whether the IL-27p28 gene polymorphisms are associated with premature coronary artery disease and/or other cardiovascular risk factors. Four IL-27p28 gene polymorphisms were selected and genotyped in 1162 premature coronary artery disease cases and 1107 controls. rs26528 T and rs40837 A alleles were significantly associated with a lower risk of premature coronary artery disease under different inheritance models (Pdominant = 0.046; Pover-dominant = 0.002; Pco-dominant1 = 0.007 for rs26528T; Pover-dominant = 0.008 and Pco-dominant1 = 0.031 for rs40837). The rs40837 A allele was also associated with a lower risk of insulin resistance, in cases (Pover-dominant = 0.037) and controls (Padditive = 0.008; Pdominant = 0.047; Precessive = 0.014; Pco-dominant2 = 0.006), while the rs26528 T allele was associated with a lower risk of insulin resistance only in the control group (Precessive = 0.016; Pco-dominant2 = 0.021). Interleukin-27 plasma levels were measured in 450 controls and 450 cases, and were significantly higher in cases compared to controls (P = 0.004). However, Interleukin-27 plasma levels were not associated with IL-27p28 polymorphisms. Luciferase assays showed that co-transfection of the rs40837 A allele and miR-379-5p significantly decreased luciferase gene expression. Our study shows for the first time, that IL-27p28 gene polymorphisms are associated with premature coronary artery disease and with some metabolic parameters. The rs40837 A allele in presence of miR-379-5p significantly decreased luciferase gene expression.

Abstract
e16037 Background: Cytotoxic (Ctx) chemotherapy can cure patients with advanced testicular cancer. Notwithstanding, Ctx agents could promote molecular aging and induce cellular senescence in vivo. This phenomenon has been studied in breast cancer patients exposed to adjuvant chemotherapy, however, the potential induction of premature immunosenescence in testicular cancer survivors (TCS) exposed to chemotherapy remains unknown. Methods: Case-control study. Cases were 18-55 yo TCS, treated with chemotherapy (≥3 BEP cycles), disease-free for ≥3 m. Controls were healthy subjects matched by sex and age ± 1 y. Selected subpopulations of isolated peripheral blood mononuclear cells (PBMC) depicted in Table, were analyzed flow cytometry. Statistics: Adjusted counts or relative percentage for each population were compared using student-t test or Mann-Whitney U test as appropriate. Results: We included 15 TCS and 15 controls. Mean age was 32.6 yo (24-54 y). Mean time since last chemotherapy was 53.13 months (3-192 m). All 15 patients were treated with at least 3 BEP cycles ± TIP/VIP cycles. There were no differences in total leucocyte (5128 ± 1917 vs 5850 ± 2141, p=0.36), and lymphocyte (1539 ± 592 vs 1889 ± 825, p=0.4) counts among cases and controls. Cases have a diminished percentage of CD3+ (63 ± 10 vs 71 ± 11, p=0.05) and CD4+ cells (36±8 vs 43 ± 9, p=0.03). There were no differences in pct of CD8+ or CD19+. However, there was an increase in late differentiated CD8+/CD57+ cells (31 ± 14% vs 20 ± 11%, p=0.02); and a decrease in CD4+/CD28+ cells (90 ± 9% vs 97 ± 4%, p=0.02) in cases. We observed paradoxical changes in B cell subpopulations with an increment in naïve (79 ±10 vs 67% ± 14% p=0.02) and a decrease in memory (18 ± 9 vs 31 ± 13%, p=0.01) B cells. Conclusions: TCS after chemo develop changes compatible with immunesenescence in T cell (CD3+) compartment, and an increment in naïve B cells. [Table: see text]

Abstract
BACKGROUND P-gp and BCRP1 are transporter proteins that may confer drug resistance. OBJECTIVE To compare P-gp and BCRP1 function in rheumatoid arthritis patients with active and inactive disease and to define their relation with disease activity. METHODS We included 17 active patients paired (age, gender, disease duration) to 17 inactive patients. All had baseline evaluations and 27 had additional six-month follow-up. P-gp and BCRP1 functional activity was measured in peripheral mononuclear cells by flow cytometry. Percentage of lymphocytes able to extrude substrates for P-gp and BCRP1 were recorded in the presence/absence of selective inhibitors. Informed consent was obtained. Descriptive statistics and linear regression model were applied. RESULTS Active patients had higher efflux function of both transporters than inactive patients: median (25-75 IQR) P-gp of 7.1% (1.4-29.3) vs. 1.6% (0.7-3.5), p = 0.02 and BCRP1 of 6.2% (1.3-22.4) vs. 1.3% (0.7-2), p = 0.007. At baseline, disease activity was the only predictor of both transporter functions. At follow-up, changes in disease activity correlated with shift in P-gp (r = 0.35, p = 0.07) and BCRP1 (r = 0.33, p=0.09) function. CONCLUSIONS Patients with active rheumatoid arthritis had a higher efflux function of P-gp and BCRP1 compared to inactive patients. The behavior of P-gp and BCRP1 appeared to be conditioned by disease activity.

Abstract
OBJECTIVE To compare drug efflux function of ABCB1 and ABCG2 transporters in rheumatoid arthritis (RA) patients with active disease and in remission. METHODS Twenty two active RA patients (DAS28 ≥3.2) and 22 patients in remission (DAS28<2.6) were selected from an early RA clinic. All patients were evaluated at study inclusion and six months later. ABCB1 and ABCG2 functional activity was measured in peripheral lymphocytes by flow cytometry. The percentage of cells able to extrude substrates for ABCB1 and ABCG2 was recorded. RESULTS Active patients had higher ABCB1 and ABCG2 activity compared with patients in remission (median [interquartile range]): 3.9% (1.4-22.2) vs (1.3% (0.6-3.2), p = 0.003 and 3.9% (1.1-13.3) vs 0.9% (0.5-1.9) p = 0.006 respectively. Both transporters correlated with disease activity assessed by DAS28, rho = 0.45, p = 0.002 and rho = 0.47, p = 0.001 respectively. Correlation was observed between the time from the beginning of treatment and transporter activity: rho = 0.34, p = 0.025 for ABCB1 and rho = 0.35, p = 0.018 for ABCG2. The linear regression model showed that DAS28 and the time from the onset of treatment are predictors of ABCB1 and ABCG2 functional activity, even after adjustment for treatment. After six months we calculated the correlation between change in DAS28 and change in the functional activity in both transporters and found a moderate and significant correlation for ABCG2 (rho = 0.28, p = 0.04) and a non-significant correlation for ABCB1 (rho = 0.22, p = 0.11). CONCLUSIONS Patients with active RA have an increased function of ABCB1 and ABCG2, and disease activity is the main determinant of this phenomena.

Abstract
A long-standing problem in quantum mechanics is the minimum number of observables required for the characterization of unknown pure quantum states. The solution to this problem is especially important for the developing field of high-dimensional quantum information processing. In this work we demonstrate that any pure d-dimensional state is unambiguously reconstructed by measuring five observables, that is, via projective measurements onto the states of five orthonormal bases. Thus, in our method the total number of different measurement outcomes (5d) scales linearly with d. The state reconstruction is robust against experimental errors and requires simple postprocessing, regardless of d. We experimentally demonstrate the feasibility of our scheme through the reconstruction of eight-dimensional quantum states, encoded in the momentum of single photons.

Abstract
BACKGROUND Paediatric age, active eczema and high number of allergens tested in poly-sensitized patients have been pinpointed as possible risk factors of systemic reactions by skin prick testing. As far as atopic eczema concerns, the higher penetration of the allergens into the skin because of the scraping or micro-injuries is an intuitive rationalization. Purpose of the present study is to provide documentary evidence that adverse reactions elicited by anomalous absorption of allergens can occur also in adult patients with apparently normal skin. METHODS Report of some exemplifying clinical and experimental observations. Measuring the inoculum volume into impaired skin and its variability in relation to the variation of the chemical-physical characteristic of the solutions used for the tests by means of a method of direct assay based on the use of a gamma-camera. RESULTS Localized impairments of the skin permeability can cause a significant increase in inoculum volume by prick-test. Critical amounts of allergens can be introduced into the skin because of the possibility of direct absorption, also without pricking, of allergy diagnostic solutions. The greater water content of the solutions used for prick-testing can significantly increase the inoculum volume. CONCLUSIONS This study adds clinical and experimental evidences that localized impairments of permeability can occur in adult patients with apparently normal skin. Special precautions should be taken when a change of the drops' normal shape and cohesion is seen, because allergy prick-testing in such areas is potentially associated with increased risk of large local or systemic reactions.

Abstract
CCL28 is a mucosa-associated epithelial-cell-produced chemokine involved in oral defense. We assessed the level of CCL28 in saliva of primary Sjögren's syndrome (pSS) patients in comparison with healthy controls and correlated it with IgA salivary levels. We included 30 non-smoker pSS patients and 30 non-smoker healthy controls paired by age (±5 years). Saliva samples were collected during the morning and kept frozen at -86 °C until the analysis. Fifty microliters of saliva was diluted 3:1 with water and analyzed for CCL28 salivary levels by ELISA method. The samples were tested in triplicate. IgA salivary levels were tested by ELISA method. We used descriptive statistics, Mann-Whitney U test and Kendall's tau correlation coefficients. pSS patients were mostly females (93.3 %), mean age 54.5 ± 13.3 years and median disease duration of 7.6 years (0.5-33). Patients with pSS had lower levels of salivary CCL28 when compared with controls [0 (0-1,272 pg/ml) vs. 94.4 (0-5,810) pg/ml, p < 0.0001]. pSS patients also had lower median levels of salivary IgA [72.55 μg/ml (0.40-297.4)] than controls [131.9 μg/ml (6.8-281.8)], although the latter results did not reach statistical significance (p = 0.51). Among the SS group, there was no correlation between CCL28 and IgA salivary levels nor between salivary IgA and disease duration, salivary flow, serum immunoglobulins or dental loss. CCL28 was absent in saliva of pSS patients; however, this finding did not correlate with salivary IgA levels.

Abstract
The scenario of a renal transplant recipient who is diagnosed with HIV infection in the late post transplant period is very uncommon. The viral infection effect on immunologic stability, regulatory cells, and allogeneic response during immune quiescence and graft acceptance provides a fertile ground in organ transplantation research and translational immunology.

Abstract
To compare the distribution of HLA-A, B, DRB1 and DQB1 alleles among Mexican patients with primary Sjögren Syndrome (pSS), secondary SS (sSS), connective tissue disease (CTD) without (w/o) SS and historical ethnically healthy controls. We included 28 pSS, 30 sSS, 96 CTD w/o SS patients and 234 controls. HLA-A, B, DRB1 and DQB1 were amplified and sequenced using the Allele SEQR Sequenced Based Typing Kits and analyzed on the ABI Prism*3130 DNA Analyzer using the Assign software. Gene frequencies were obtained by direct counting. Contingence tables of 2 × 2 were generated and analyzed by the Mantel-Haenzel χ (2) or Fisher's test (EPIINFO program). We reported odds ratios (OR) and corrected p values. SS patients showed increased frequencies of A*68:01 and DRB1*14:06 alleles when compared to CTD w/o SS (OR 4.43, 95 % CI 1.35-14.14, p = 0.007 and OR 14, 95 % CI 1.68-116, p = 0.001, respectively) and a higher prevalence of DRB1*01:01 (OR 5.9, 95 % CI 2.13-16.56, p = 0.003) and HLA-B*35:01 (OR 3.70, 95 % CI 1.92-7.12, p = 0.004) when compared with controls. pSS patients had a higher frequency of DRB1*14:06 allele than sSS (OR 16, 95 % CI 1.59-390, p = 0.001). Anti-Ro/SSA positivity was associated with B*51:01 (OR 10.11, 95 % CI 1.09-245, p = 0.02) and DRB1*03:01 alleles (OR 4.26, 95 % CI 1.01-18.89, p = 0.029), whereas the A*01:01 allele was associated with anti-La/SSB positivity (OR 4.75, 95 % CI 1.32-16.92, p = 0.003). In our population, the DRB1*14:06 allele was associated with primary and secondary SS implying that both varieties bear a similar immunogenetic background.

Abstract
Epidemiological investigations in representative chickpea (Cicer arietinum L.) fields in southern Italy (Larino, Campobasso, 41°50'45″ N, 14°55'28″ E) identified severe withering (25 to 51%) of plants during flowering. Diseased plants showed a reduced total root biomass associated with less vigorous and chlorotic foliage. Browning and necrosis of subcortical and xylematic tissues of the crown and main roots were observed in affected plants. Symptomatic root and stem portions from 50 plants were sampled, surface disinfected with a sodium hypochlorite water solution (2% v/v for 2 min), rinsed with sterile distilled water, and placed in petri dishes containing potato dextrose agar with streptomycin sulfate (200 mg/l) and incubated at 25°C for 10 days. The most frequent fungal colony isolated showed macro- and microscopic characters specific of the genus Fusarium (3), with falcate and three-septate macroconidia (24.0 to 43.8 μm long) and microconidia (6.8 to 10.4 μm long) with zero or one septa. The ribosomal DNA of the fungal isolate processed by PCR using the ITS1F/ITS4 primers (2) produced an amplicon of 545 bp (ENA, Accession No. HG423346). A BLAST search with the amplified sequence in the database of the International Mycological Association ( www.mycobank.org ) revealed 99% identity with F. oxysporum sequences. Additional molecular analysis using the specific primers Foc0-12/Foc0-12rf for F. oxysporum f.sp. ciceris (Foc) produced an amplicon only in the chickpea virulent strain Foc-7952, race 0 (1) used as control; furthermore, PCR amplification for the Pisatin Demetylase gene by using the specific primers PDAF2a and PDAR3a (4) yielded the expected amplicon only for the new isolate, whereas no amplification was obtained with the control strain Foc-7952. Pathogenicity assays were carried out to complete Koch's postulates. To this aim, horticultural peat was infested with a conidial suspension (1 × 104 conidia/g of soil) from the new fungal pathogen, dispensed in plastic pots, and sown with surface sterilized seeds of chickpea (cv. Real, ISEA, Italy). Uncontaminated peat was used as control. For both treatments, 3 replicates of 10 seeds were used and experiments repeated twice. The plastic pots were kept in a growth chamber (28°C; 70% RH; 15/9 h light/dark) where the first disease symptoms on plants appeared 20 days after sowing. At the end of the experiments, all plants inoculated with the new isolate showed a high disease severity (98%), whereas non-inoculated plants remained healthy. The seedlings from infested soil demonstrated the same symptoms previously observed in the field, and after re-isolation, the causal agent demonstrated the same morphological features of the isolate used for inoculation. Pathogenicity tests were performed on pea, faba bean, melon, and tomato by using three cultivars for each crop. The results demonstrated high virulence of the new isolate of F. oxysporum f.sp. pisi (Fop) on both chickpea and pea with seed germination reduction, rot on main and secondary roots and cotyledonary leaves, and root biomass reduction and foliage chlorosis. No symptoms were observed on other inoculated vegetal species. Collectively, data of our investigation allow us to affirm that this is the first report of Fop as a new pathogen of chickpea. This result has great economic importance since it enables specific monitoring and management plans for this new disease caused by Fop on chickpea, a key crop for human and animal nutrition.

Abstract
The secure transfer of information is an important problem in modern telecommunications. Quantum key distribution (QKD) provides a solution to this problem by using individual quantum systems to generate correlated bits between remote parties, that can be used to extract a secret key. QKD with D-dimensional quantum channels provides security advantages that grow with increasing D. However, the vast majority of QKD implementations has been restricted to two dimensions. Here we demonstrate the feasibility of using higher dimensions for real-world quantum cryptography by performing, for the first time, a fully automated QKD session based on the BB84 protocol with 16-dimensional quantum states. Information is encoded in the single-photon transverse momentum and the required states are dynamically generated with programmable spatial light modulators. Our setup paves the way for future developments in the field of experimental high-dimensional QKD.

Abstract
We have identified Tspan33 as a gene encoding a transmembrane protein exhibiting a restricted expression pattern including expression in activated B cells. TSPAN33 is a member of the tetraspanin family. TSPAN33 is not expressed in resting B cells, but is strongly induced in primary human B cells following activation. Human 2E2 cells, a Burkitt's lymphoma-derived B cell model of activation and differentiation, also upregulate TSPAN33 upon activation. TSPAN33 is expressed in several lymphomas including Hodgkin's and Diffuse large B cell lymphoma. TSPAN33 is also expressed in some autoimmune diseases where B cells participate in the pathology, including rheumatoid arthritis patients, systemic lupus erythematosus (SLE), and in spleen B cells from MRL/Fas(lpr/lpr) mice (a mouse model of SLE). We conclude that TSPAN33 may be used as a diagnostic biomarker or as a target for therapeutic antibodies for treatment of certain B cell lymphomas or autoimmune diseases.

Abstract
Any practical realization of entanglement-based quantum communication must be intrinsically secure and able to span long distances avoiding the need of a straight line between the communicating parties. The violation of Bell's inequality offers a method for the certification of quantum links without knowing the inner workings of the devices. Energy-time entanglement quantum communication satisfies all these requirements. However, currently there is a fundamental obstacle with the standard configuration adopted: an intrinsic geometrical loophole that can be exploited to break the security of the communication, in addition to other loopholes. Here we show the first experimental Bell violation with energy-time entanglement distributed over 1 km of optical fibres that is free of this geometrical loophole. This is achieved by adopting a new experimental design, and by using an actively stabilized fibre-based long interferometer. Our results represent an important step towards long-distance secure quantum communication in optical fibres.

Abstract
BACKGROUND Localized scleroderma (LS) is a disfiguring inflammatory autoimmune disease of the skin and underlying tissue. As in systemic sclerosis, a key feature is the presence of T cells in inflammatory lesions. AIM To evaluate the effect of polymerized type I collagen vs. methylprednisolone (MP) in LS, and to determine the influence of this polymerized collagen (PC) on CD4+ peripheral T cells expressing interleukin (IL)-4, IL-17A, interferon-γ and Forkhead box protein (Foxp)3, and on cells expressing transforming growth factor (TGF)-β1, IL-17A, IL-22 and Foxp3 in the skin. METHODS In total, 16 patients with LS were treated for 3 months with monthly subcutaneous intralesional injections of 0.1 mL MP (giving a total dose of 20 mg/mL each month) and 15 patients were treated, with weekly subcutaneous intralesional injections of PC, ranging from 0.2 mL (equivalent to 1.66 mg collagen) for a lesion of 50 mm in size, up to a maximum of 1.0 mL (8.3 mg collagen) for a lesion > 100 mm in size, and followed up for a further 6 months. Skin biopsies were obtained from lesions at baseline (before treatment) and 9 months later (6 months after treatment end). Tissue sections were evaluated by histology and immunohistochemistry (IL-17A, IL-22, TGF-β1 and Foxp3). CD4+ T-cell subsets were determined in peripheral blood by flow cytometry. RESULTS Abnormal tissue architecture was seen in the biopsies taken from patients treated with MP, whereas the PC treatment restored normal skin architecture. PC downregulated pro-inflammatory/profibrotic cytokine expression in peripheral cells, and upregulated the number of regulatory T cells (Tregs) in skin. PC was safe and well tolerated. CONCLUSIONS PC is not only an antifibrotic/fibrolytic agent but also an immunomodulator biodrug that restores the balance between T helper (Th)1, Th2, Th17 and Tregs, downregulates production of pro-inflammatory or profibrogenic cytokines (IL-17A, IL-22 and TGF-β1), and renews skin architecture, without adverse effects.
