Valutazione dei genotipi G6PD nella popolazione Siciliana e identificazione di una nuova variante: “G6PD*Palermo R257M”.
2008
La deficienza enzimatica di G6PDH è uno dei più comuni disordini nella popolazione siciliana in quanto più di 400 milioni di persone ne sono affette. Al fine di valutare la reale prevalenza dei casi nel nostro territorio presentiamo i dati di uno studio di genotipizzazione del locus G6PD (Xq28). 349 soggetti Siciliani di sesso maschile affetti da deficienza di G6PDH sono stati tipizzati secondo varie metodiche. Gli approcci di laboratorio sono: RFLPs (NlaIII, BclI, PstI e BspHI), PCR-Reverse Dot Blot (RDB) ed il sequenziamento diretto del gene. Le prime metodiche sono utili per definire le mutazioni già descritte e comunque le più comuni; il sequenziamento diretto è determinante per la valu…
XIII Starptautiskais baltistu kongress „Baltu valodas laikā un telpā”: Referātu tēzes
2021
2021. gada 13.–15. oktobrī Latvijas Universitāte tiešsaistē organizēja XIII Starptautisko baltistu kongresu “Baltu valodas laikā un telpā”, kurā piedalījās vairāk nekā 170 dalībnieku no 11 valstīm. Kongresa aizsākumi meklējami 1965. gadā, kad Viļņas universitātes Lietuviešu valodas katedras un Lietuviešu valodas institūta darbinieki sarīkoja baltu valodu vēsturei veltītu konferenci. Starptautiskais baltistu kongress ik pēc pieciem gadiem pārmaiņus notiek Viļņā vai Rīgā. Kongresa tēžu krājumā apvienots plašs tēmu loks, sākot no baltu valodu likteņiem laika nogriežņos (diahronijā), līdz skatījumam uz valodu pašreizējā stāvoklī (sinhronijā): valodas vēsture, gramatika, onomastika, sociolingvis…
Genetic contribution in sporadic thoracic aortic aneurysm? Emerging evidence of genetic variants related to TLR-4-mediated signaling pathway as risk …
2015
Abstract Sporadic thoracic aortic aneurysms (TAA) and dissections are one of the major causes of morbidity and mortality worldwide, especially in those older than 65 years. The presentation of TAA is varied and often silent. Thus, sporadic TAA detection is often fortuitous, with identification occurring during a routine physical examination or during an unrelated medical evaluation. Once suspected, confirmation by imaging clinical approaches is needed to allow the choose of the unique treatments for TAA, namely the surgery procedures, including elective surgery or endovascular repair before the onset of catastrophic and fatal complications, such as dissection or rupture. At present, there a…
Multiple independent variants at the TERT locus are associated with telomere length and risks of breast and ovarian cancer
2013
Journal article TERT-locus SNPs and leukocyte telomere measures are reportedly associated with risks of multiple cancers. Using the Illumina custom genotyping array iCOGs, we analyzed ~480 SNPs at the TERT locus in breast (n = 103,991), ovarian (n = 39,774) and BRCA1 mutation carrier (n = 11,705) cancer cases and controls. Leukocyte telomere measurements were also available for 53,724 participants. Most associations cluster into three independent peaks. The minor allele at the peak 1 SNP rs2736108 associates with longer telomeres (P = 5.8 × 10!-7), lower risks for estrogen receptor (ER)-negative (P = 1.0 × 10!-8) and BRCA1 mutation carrier (P = 1.1 × 10!-5) breast cancers and altered promot…
Abitare nel reale. Dalla crisi della periferia alla tessitura di nuove relazioni contestuali
2019
I progetti redatti per “Palermo Sud-Est” sono il risultato di un Laboratorio di Laurea strutturatosi attraverso incontri, seminari, comunicazioni specialistiche, esposizioni critiche, che – in una strategia condivisa – ha visto ogni studente elaborare il proprio lavoro nel confronto con gli altri attori del Laboratorio stesso. La ricerca sui “progetti urbani” è stata impostata di modo che ogni laureando fosse messo a conoscenza dei progetti svolti nello stesso ambito territoriale dai colleghi che l’avevano preceduto, così da poter operare in continuità e contribuire a formulare un ragionamento unitario, nel quale ogni progetto costituisse continuazione, verifica o anche variante dei precede…

Examination of Escherichia coli from poultry for selected adhesin genes important in disease caused by mammalian pathogenic E. coli
2001
A collection of 1601 extraintestinal and intestinal Escherichia coli isolated from chickens, turkeys and ducks, in Belgium, France and Spain, was hybridised with gene probes specific for fimbrial and afimbrial adhesins (F17, F18, SSfa/F1C, Bfp, Afa, Cs31A, IntiminEae, Aida-1) of intestinal, urinary and invasive E. coli of mammals and with a probe specific for the P (Pap/Prs) fimbrial adhesin of urinary and invasive E. coli of mammals and birds. Three hundred and eighty-three strains (23.9%) were P-positive, 76 strains (4.8%) were Afa-positive, 75 strains (4.7%) were F17-positive, 67 strains (4.2%) were S-positive, 23 (1.4%) were Intimin-positive, and all were F18-, Cs31A-, Aida1- and Bfp-ne…
Identifying gene-environment interactions in schizophrenia: contemporary challenges for integrated, large-scale investigations
2014
European Community Recent years have seen considerable progress in epidemiological and molecular genetic research into environmental and genetic factors in schizophrenia, but methodological uncertainties remain with regard to validating environmental exposures, and the population risk conferred by individual molecular genetic variants is small. There are now also a limited number of studies that have investigated molecular genetic candidate gene-environment interactions (G x E), however, so far, thorough replication of findings is rare and G x E research still faces several conceptual and methodological challenges. in this article, we aim to review these recent developments and illustrate h…
INTEGRATIVE APPROACH BETWEEN GENE VARIANTS, NEUROENDOCRINE EFFECTORS AND ANXIETY RESPONSE: A PILOT STUDY
2016
The aim of this study is to investigate the neurobiology of stress/emotionality, creating a multidisciplinary assessment model, which can help to provide psychological and physiological responses depending on the genetic background related to sport performances, social closeness and performance anxiety management in team sports. We enrolled 20 female volleyball players aged 13 ± 1 years old played in two different teams during a regional championship final. Saliva collection was carried out before and after the match. In order to evaluate the neuroendocrine effectors involved in stress and performance, we analyzed cortisol and progesterone levels through Elisa standard kit as well as HSP70 …
iGEMS : an integrated model for identification of alternative exon usage events
2016
DNA microarrays and RNAseq are complementary methods for studying RNA molecules. Current computational methods to determine alternative exon usage (AEU) using such data require impractical visual inspection and still yield high false-positive rates. Integrated Gene and Exon Model of Splicing (iGEMS) adapts a gene-level residuals model with a gene size adjusted false discovery rate and exon-level analysis to circumvent these limitations. iGEMS was applied to two new DNA microarray datasets, including the high coverage Human Transcriptome Arrays 2.0 and performance was validated using RT-qPCR. First, AEU was studied in adipocytes treated with (n = 9) or without (n = 8) the anti-diabetes drug,…
