    The process which gives life to artworks because painters are inspired by the charm of the Sky is a well-known process. Beauty and mystery of Cosmos have always given mankind, and still give, a lot of masterpieces, from the Halley comet painted by Giotto in the Scrovegni Chapel to the Starry Nights by Vincent Van Gogh. But, what to say about the opposite process? How could art inspire science? In many ways but we propose here one in a format appropriate for science communication. We start from some paintings of Alessandro Rinaldi, an Italian quoted artist present at 54th Biennale International Art Exhibition of Venice. Focusing our attention on few Rinaldi paintings representing some cosmic scenes, such as starry skies, constellations, moons, we will perform a dialogue between Science and Art, played by two women. The dialogue will be written assembling skills in astrophysics, science communication, screenwriting and art. Final product will be a drama performed in a particular theatre, built primarily for educational and entertaining shows about astronomy and the night sky: a planetarium. Public will be involved in an immersive show of artistic and astronomical images, and will listen to the two characters, Lady A and Lady S, discussing both artistic and scientific aspects of each painting: from the raw material used for painting to the real knowledge of represented celestial objects. Few, selected and correct astronomical notions will be conveyed in a new, funny and attractive way also for people not quite interested in science. The proposed format could be regarded as new for science outreach, where Astronomy could be replaced with Natural and Environmental Sciences, while dialogues around scientific issues could be performed inside planetariums as well on other stages. But there is more: well also tell public that Science doesn’t make Art loose her charm and beauty, rather she makes her stronger because mindful of her potential; Art doesn’t make science loose her strictness and reliability, rather she makes her stronger because mindful of her beauty. Public will have the opportunity of seeing real artworks in a exhibit inside the planetarium and filling in a questionnaire before and after the show. In this way changing in scientific notions and the related perception of artworks will be collected in order to have a realistic feedback about the efficiency of our project

    Source Department of Medicine and Pneumology, V Cervello Hospital, Via Trabucco 180, 90146 Palermo, Italy. [email protected] Abstract BACKGROUND AND METHODS: Host may have a role in the evolution of chronic HCV liver disease. We performed two cross-sectional prospective studies to evaluate the prevalence of cirrhosis in first degree relatives of patients with cirrhosis and the role of two major histocompatibility complex class III alleles BF and C4 versus HCV as risk factors for familial clustering. FINDINGS: Ninety-three (18.6%) of 500 patients with cirrhosis had at least one cirrhotic first degree relative as compared to 13 (2.6%) of 500 controls, (OR 7.38; CI 4.21-12.9). C4BQ0 was significantly more frequent in the 93 cirrhotic patients than in 93 cirrhotic controls without familiarity (Hardy-Weinberg equilibrium: chi2 5.76, P = 0.016) and in 20 families with versus 20 without aggregation of HCV related cirrhosis (29.2% versus 11.3%, P = 0.001); the association C4BQ0-HCV was found almost only in cirrhotic patients with a family history of liver cirrhosis. CONCLUSIONS: Our studies support the value of C4BQ0 as a risk indicator of familial HCV related cirrhosis

    PCSK9-D374Y mediated LDL-R degradation can be functionally inhibited by EGF-A and truncated EGF-A peptides: An in vitro study

    Get PDF
    Background and aims: Proprotein convertase subtilisin/kexin type 9 (PCSK9) binds to low density lipoprotein receptor (LDLR) through the LDLR epidermal growth factor-like repeat A (EGF-A) domain and induces receptor internalization and degradation. PCSK9 has emerged as a novel therapeutic target for hypercholesterolemia. Clinical studies with PCSK9 inhibiting antibodies have demonstrated strong LDL-c lowering effects, but other therapeutic approaches using small molecule inhibitors for targeting PCSK9 functions may offer supplementary therapeutic options. The aim of our study was to evaluate the effect of synthetic EGF-A analogs on mutated (D374Y) PCSK9-D374Y mediated LDLR degradation in vitro. Methods: Huh7 human hepatoma cells were transiently transfected to overexpress the gain-of-function D374Y PCSK9 mutation, which has been associated with severe hypercholesterolemia in humans. Results: Transient transfection of cells with PCSK9-D374Y expression vector very effectively enhanced degradation of mature LDLR in Huh7. Treatment with both EGF-A and EGF-A truncated peptides inhibited this effect and showed increased LDLR protein in Huh7 cells transfected with PCSK9-D374Y in a clear concentration dependent manner. Huh7 transfected cells treated with increasing concentration of EGF-A analogs also showed an increase internalization of labeled Dil-LDL. Conclusions: The result of our study shows that EGF-A analogs are able to effectively hamper the enhanced degradation of LDLR in liver cells expressing PCSK9-D374Y

    The acute phase of Mediterranean spotted fever (MSF) is characterized by dramatic changes in cytokine production patterns, clearly indicating their role in the immunomodulation of the response against the microorganism, and the differences in cytokine production seem to influence the extent and severity of the disease. In this study, the single nucleotide polymorphisms (SNPs) of tumor necrosis factor alpha (TNF-Ξ±) -308G/A (rs1800629) and interleukin-10 (IL-10) -1087G/A (rs1800896), -824C/T (rs1800871), and -597C/A (rs1800872) and the gamma interferon (IFN-Ξ³) T/A SNP at position +874 (rs2430561) were typed in 80 Sicilian patients affected by MSF and in 288 control subjects matched for age, gender, and geographic origin. No significant differences in TNF-Ξ± -308G/A genotype frequencies were observed. The +874TT genotype, associated with an increased production of IFN-Ξ³, was found to be significantly less frequent in MSF patients than in the control group (odds ratio [OR], 0.18; 95% confidence interval [95% CI], 0.06 to 0.51; P corrected for the number of genotypes [Pc], 0.0021). In addition, when evaluating the IFN-Ξ³ and IL-10 genotype interaction, a significant increase of +874AA/-597CA (OR, 5.31; 95% CI, 2.37 to 11.88; Pc, 0.0027) combined genotypes was observed. In conclusion, our data strongly suggest that finely genetically tuned cytokine production may play a crucial role in the regulation of the immune response against rickettsial infection, therefore influencing the disease outcomes, ranging from nonapparent or subclinical condition to overt or fatal disease

    The study of the genetic profile of centenarians aims to identify the genes and allelic variants which may influence a greater life expectancy and that can be considered as predisposing factors associated to the aging diseases, such as Alzheimer. Centenarians, that represent a cohort of selected survivors, show an hypercoagulability state characterised by striking signs of high coagulation enzyme activity, as directly assessed by the tested higher plasma level of some important factors involved in the haemostasis balance. Anyway, these individuals seem to have a reduced susceptibility to dementia, as well as to cardiovascular events. In this study we analyze the frequencies of Leiden Factor V polymorphism (G1691A), and G20210A of prothrombin (FII) in three cohorts of subjects: patients with Alzheimer\u2019s disease (unsuccessful aging), nonagenarians (successful aging) and young healthy controls, to assess whether allelic variants associated to the modification of haemostatic system function, may play a role in the protection or susceptibility to Alzheimer disease, as well as to reach a successful aging. No significant differences were observed in the frequencies of the three groups studied. These results indicate that the presence or absence of the gene variants examined did not influence the achievement of advanced age and are not risk factors for Alzheimer\u2019s disease. The state of hypercoagulability and the possession of these risk alleles appear to be compatible with the achievement of longevity and are not implied as risk factors in Alzheimer disease development

    Aim. To determine ultrasound, computed tomography and angiographic image characteristics for soft tissue hemorrhages/hematomas, the sequence of using imaging methods in patients infected with SARS-CoV-2, to study the morphology of changes in soft tissues, to determine the essence of the concept and to develop treatment tactics for this complication of COVID-19.Material and methods. During 4 months of treatment of elderly patients (+60) infected with SARS-CoV-2, 40 patients were identified with soft tissue hemorrhages/hematomas, of which 26 (65%) patients with large hematomas (>10 cm in size and > 1000 ml in volume). The analysis of clinical and laboratory parameters, methods of instrumental diagnostics (ultrasound – 26 patients, CT – 10 patients, angiography – 9 patients, punctures – 6 patients) was carried out; autopsy material was studied in 11 cases.Results. Image characteristics of hemorrhages/hematomas of soft tissue density were obtained using modern instrumental methods, and the sequence of application of visualization methods was determined. A tactic for managing a patient with stopped and ongoing bleeding has been developed. The morphological substrate of hemorrhagic complications in a new viral infection was studied. All patients were treated with conservative and minimally invasive procedures (embolization, puncture with pressure bandage). 15 patients (57.7%) recovered, 11 patients (42.3%) died from the progression of COVID-19 complications.Conclusion. Comprehensive clinical and laboratory sequential instrumental diagnosis of soft tissue hemorrhages in COVID-19. Treatment should be conservative and significantly invasive. The use of the term β€œsoft tissue hematoma” in SARS-CoV-2 infected patients is not a natural quality of the normal pathological process and should not be observed from our point of view.ЦСль исслСдования: ΠΎΠΏΡ€Π΅Π΄Π΅Π»ΠΈΡ‚ΡŒ Π²ΠΈΠ·ΡƒΠ°Π»ΡŒΠ½Ρ‹Π΅ ΡƒΠ»ΡŒΡ‚Ρ€Π°Π·Π²ΡƒΠΊΠΎΠ²Ρ‹Π΅, ΠΊΠΎΠΌΠΏΡŒΡŽΡ‚Π΅Ρ€Π½ΠΎ-томографичСскиС ΠΈ ангиографичСскиС ΠΊΡ€ΠΈΡ‚Π΅Ρ€ΠΈΠΈ мягкотканных кровоизлияний/Π³Π΅ΠΌΠ°Ρ‚ΠΎΠΌ, ΠΏΠΎΡΠ»Π΅Π΄ΠΎΠ²Π°Ρ‚Π΅Π»ΡŒΠ½ΠΎΡΡ‚ΡŒ использования ΠΌΠ΅Ρ‚ΠΎΠ΄ΠΎΠ² Π²ΠΈΠ·ΡƒΠ°Π»ΠΈΠ·Π°Ρ†ΠΈΠΈ Ρƒ Π±ΠΎΠ»ΡŒΠ½Ρ‹Ρ…, ΠΈΠ½Ρ„ΠΈΡ†ΠΈΡ€ΠΎΠ²Π°Π½Π½Ρ‹Ρ… SARS-CoV-2, ΠΈΠ·ΡƒΡ‡ΠΈΡ‚ΡŒ ΠΌΠΎΡ€Ρ„ΠΎΠ»ΠΎΠ³ΠΈΡŽ ΠΈΠ·ΠΌΠ΅Π½Π΅Π½ΠΈΠΉ Π² мягких тканях, ΠΎΠΏΡ€Π΅Π΄Π΅Π»ΠΈΡ‚ΡŒ ΡΡƒΡ‚ΡŒ понятия ΠΈ Π²Ρ‹Ρ€Π°Π±ΠΎΡ‚Π°Ρ‚ΡŒ Π»Π΅Ρ‡Π΅Π±Π½ΡƒΡŽ Ρ‚Π°ΠΊΡ‚ΠΈΠΊΡƒ ΠΏΡ€ΠΈ Ρ‚Π°ΠΊΠΎΠΌ ослоТнСнии COVID-19.ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π» ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹.
