Genetic and Epigenetic Characteristics of Inflammatory Bowel Disease-Associated Colorectal Cancer.
2021
doi: 10.1053/j.gastro.2021.04.042 Background & Aims Inflammatory bowel disease (IBD) is a chronic, relapsing inflammatory disorder associated with an elevated risk of colorectal cancer (CRC). IBD-associated CRC (IBD-CRC) may represent a distinct pathway of tumorigenesis compared to sporadic CRC (sCRC). Our aim was to comprehensively characterize IBD-associated tumorigenesis integrating multiple high-throughput approaches, and to compare the results with in-house data sets from sCRCs. Methods Whole-genome sequencing, single nucleotide polymorphism arrays, RNA sequencing, genome-wide methylation analysis, and immunohistochemistry were performed using fresh-frozen and formalin-fixed tissue sam…
FT-IR spectroscopy : A powerful tool for studying the inter- and intraspecific biodiversity of cultivable non-Saccharomyces yeasts isolated from grap…
2016
International audience; The efficiency of the FT-IR technique for studying the inter- and intra biodiversity of cultivable non-Saccharomyces yeasts (NS) present in different must samples was examined. In first, the capacity of the technique FF-IR to study the global diversity of a given sample was compared to the pyrosequencing method, used as a reference technique. Seven different genera (Aureobasidium, Candida, Cryptococcus, Hanseniaspora, Issatchenkia, Metschnikowia and Pichia) were identified by FT-IR and also by pyrosequencing. Thirty-eight other genera were identified by pyrosequencing, but together they represented less than 6% of the average total population of 6 musts. Among the sp…
Stinging nettle (Urtica dioica L.) as a functional food additive in egg pasta: Enrichment and bioaccessibility of Lutein and β-carotene
2018
Abstract The use of stinging nettles as an ingredient in egg pasta has been evaluated with respect to food enrichment with carotenoids. Bioaccessibility of lutein and β-carotene has been estimated by dynamic simulation of the digestion process, with particular attention to duodenum and colon stages. Higher bioaccessibility for the two carotenoids occurs between 2 and 24 h of colonic fermentation and it is around 35% for lutein and 10% for β-carotene. However, the results reveal that the food matrix has a significant role in carotenoid release during the digestion process. In general, nettle enriched pasta has a lower carotenoid bioaccessibility than dietary supplement at duodenum and after …
Arvovallan ja vakauden puolesta : Jugoslavian hajoaminen Ranskan parlametin keskusteluissa vuosina 1991-1995
2013
Tässä tutkimuksessa perehdytään niihin tulkintoihin, joita Ranskan parlamentissa esitettiin vuosina 1991–1995 Jugoslavian hajoamista seuranneeseen konfliktiin liittyen sekä siihen, miten tulkinnoista muodostui Ranskan sisäpoliittinen kysymys. Hallitukselle esitetyistä kysymyksistä on muodostunut tärkeä parlamentaarinen instrumentti, jonka avulla parlamentaarikoiden on mahdollista pakottaa haluamansa aiheet osaksi valtiopäivätyöskentelyä. Ensisijaisen tutkimusaineiston muodostavatkin Ranskan parlamentin istuntopöytäkirjoista löytyvät hallitukselle esitetyt kysymykset, joita täydentävät (entistä) Jugoslaviaa koskevat hallituksen tiedonannot. Aineistoa lähestytään noudattamalla Quentin Skinner…
Clinical evaluation of pancreatitis-associated protein as a serum marker of hepatocellular carcinoma: Comparison with α-fetoprotein
1998
This study evaluated the significance of serum pancreatitis-associated protein (PAP) assay, as a marker of hepatocellular carcinoma (HCC), in comparison and combined with α-fetoprotein (AFP) assay. Sixty-five patients with HCC, 59 with liver cirrhosis (LC) and 68 asymptomatic controls (C) were studied. PAP and AFP values significantly increased from C to LC and HCC group (p < 0.0001). The area under receiver-operating characteristic (ROC) curve for the two markers was not statistically different. At 100% specificity, ROC analysis gave a cut-off level for AFP of 166 IU/l with 40% sensitivity, and a cut-off level of 240 µg/l for PAP with 23% sensitivity. Diagnostic accuracy of combined AFP…
Pancreatitis-associated protein in patients with celiac disease: Serum levels and immunocytochemical localization in small intestine
1997
Since PAP is a stress protein expressed in human pancreas during pancreatitis but also constitutively synthesized in the small intestine, we looked whether its expression would be altered in patients with celiac disease. Serum PAP concentrations were determined consecutively in 54 patients with celiac disease on a free diet (group A), in 47 patients with celiac disease on a gluten-free diet (group B), in 22 patients with other intestinal pathologies but with normal intestinal mucosa (group C), in 14 patients with retarded growth, no gastrointestinal disease and normal intestinal mucosa (group D), and in 17 controls (group E). Serum PAP levels (ng/ml) were significantly higher in group A (12…
La antropología como ciencia libidinosa. Diderot y el viaje de Bougainville
2005
Son innumerables los estudios que han abordado, desde temprano, la historia de la constitución de la antropología como disciplina empírica con vocación 'científica', como una de las ciencias humanas. Se muestra así una cierta obsesión por los orígenes, quizá síntoma de una frágil identidad. Uno de esos textos, de los más tempranos, The History of Anthropology} 1 fue escrito por Boas justo al principio del siglo pasado (1904) y tiene por objeto -fue una conferencia dada ante un publico académico variopintoreflexionar históricamente sobre una disciplina que todavía se debate para delimitar cuál es su objeto y método epistemológicos. Boas advierte desde el principio que no va a proceder dicien…

Analysis of the Relationship Between Context and Solution Plan in Modelling Tasks Involving Estimations
2021
In this chapter we analyse students’ written solution plan of a sequence of modelling tasks involving estimations. Our research objective is to statistically analyse whether there is a relation between the solution plan and the characteristics of the context of the real estimation task. From previous work, we have identified some task variables that are directly related to the context. In this study we have designed a sequence of modelling tasks and we have analysed the productions of N = 224 Spanish pre-service primary school teachers. The results show that there is a relationship between the variables of the task and the solution plan used by the students in each case. From the results of…
HPLC-UV/Vis-APCI-MS/MS Determination of Major Carotenoids and Their Bioaccessibility from "Delica" (Cucurbita maxina) and "Violina" (Cucurbita moscha…
2018
Carotenoids are a widespread group of fat-soluble pigments, and their major nutritional importance comes from their pro-vitamin A activity and their antioxidant capacity. In this study, two different pumpkin cultivars (Cucurbita maxima, also named `Delica&rsquo
