The distribution of active RNA polymerase II along the transcribed region is gene-specific and controlled by elongation factors.

2010

In order to study the intragenic profiles of active transcription, we determined the relative levels of active RNA polymerase II present at the 3'- and 5'-ends of 261 yeast genes by run-on. The results obtained indicate that the 3'/5' run-on ratio varies among the genes studied by over 12 log(2) units. This ratio seems to be an intrinsic characteristic of each transcriptional unit and does not significantly correlate with gene length, G + C content or level of expression. The correlation between the 3'/5' RNA polymerase II ratios measured by run-on and those obtained by chromatin immunoprecipitation is poor, although the genes encoding ribosomal proteins present exceptionally low ratios in …

Participants’ home as an interview context when studying sensitive family issues

2013

This article considers the meaning of the participants’ home as an interview context when studying sensitive family issues. The article is based on two qualitative family studies by the authors on foster children’s perspectives on their home and their family relations and client families’ experiences of preventive family support. Both studies address sensitive family issues, in particular Finnish child welfare. The first author’s interview data consist of interviews with foster children, social network maps and diaries and the second author’s data of interviews with six client families. Most of the interviews were conducted at the participants’ homes, but in the second author's study two in…

Bioactive glass ions induce efficient osteogenic differentiation of human adipose stem cells encapsulated in gellan gum and collagen type I hydrogels

2019

Abstract Background Due to unmet need for bone augmentation, our aim was to promote osteogenic differentiation of human adipose stem cells (hASCs) encapsulated in gellan gum (GG) or collagen type I (COL) hydrogels with bioactive glass (experimental glass 2-06 of composition [wt-%]: Na2O 12.1, K2O 14.0, CaO 19.8, P2O5 2.5, B2O3 1.6, SiO2 50.0) extract based osteogenic medium (BaG OM) for bone construct development. GG hydrogels were crosslinked with spermidine (GG-SPD) or BaG extract (GG-BaG). Methods Mechanical properties of cell-free GG-SPD, GG-BaG, and COL hydrogels were tested in osteogenic medium (OM) or BaG OM at 0, 14, and 21 d. Hydrogel embedded hASCs were cultured in OM or BaG OM fo…

Identificación del gen MALT1 como oncogén dominante en el linfoma MALT.

2005

En los linfomas no Hodgkin (LNH), las traslocaciones primarias características dan lugar a la desregulación de un protooncogén (debido en un gran número de casos al reordenamiento con el gen de las inmunoglobulinas) y cuya consecuencia funcional es la alteración de la expresión génica con potencial neoplásico. Otro tipo de lesión genética frecuente es la delección cromosómica que inactiva genes supresores tumorales, por ejemplo p53 ó p16. Estas anomalías se identifican junto a las traslocaciones primarias y se consideran alteraciones secundarias relacionadas con la progresión y transformación tumoral. También la amplificación génica es otro mecanismo de reordenamiento molecular frecuente en…

SULLA FAUNA AD OSTRACODI (CRUSTACEA: STRACODA) NON-MARINI RECENTI DI ALCUNE ISOLE DEL MEDITERRANEO CENTRALE: SICILIA,ARCIPELAGHI CIRCUM-SICILIANI E M…

2009

Le conoscenze relative alla fauna ad ostracodi delle acque interne dei paesi del Mediterraneo centro-meridionale risultano ad oggi piuttosto lacunose e frammentarie e per molte aree geografiche non sono disponibili studi organici né checklist aggiornate. Al fine di contribuire a colmare questo iato conoscitivo, nel periodo compreso tra il 2000 ed il 2008 sono stati realizzati una serie di campionamenti incentrati sugli ambienti acquatici ad idroperiodo temporaneo della Sicilia e di gran parte delle isole circum-siciliane; i risultati conseguiti con queste campagne di raccolta hanno consentito di ottenere un primo quadro d’insieme sulla attuale presenza e distribuzione dei Podocopida nell’ar…

Valutazioni di efficienza di rivelatori HPGe con il codice MCNP5

2008

Sono presentate alcune simulazioni con il codice MCNP5 di rivelatori di fotoni di tipo HPGe (High Purity Germanium) per la valutazione di efficienze per alcune geometrie usualmente impiegate in misure di tipo radioprotezionistico (Marinelli beakers, a disco, etc). Il modello del rivelatore è validato mediante confronti con determinazioni sperimentali di sorgenti puntiformi calibrate di tipo “single line”, caratterizzate dalla emissione di un solo fotone gamma per disintegrazione. L’ottimizzazione è realizzata valutando in tutto il range energetico di interesse le differenze tra i valori simulati e sperimentali di efficienza, sia fotoelettrica che totale, al variare di alcuni dei parametri c…

Ancora sulle "esplosive palatali" nelle inchieste dell'Atlante Linguistico del Mediterraneo (ALM): i punti albanesi

2021

Tra i «Problemi redazionali» emersi in fase di controllo e organizzazione dei materiali giunti dalla campagna di rilevamenti dell’Atlante Linguistico del Mediterraneo (ALM), Berruto (1971-1973) rileva la proliferazione e l’eterogeneità di alcune scelte grafemiche operate da diversi raccoglitori che, impegnati in una trascrizione più o meno puntuale delle risposte ottenute, avevano interpretato e risolto variamente alcune delle indicazioni previste nel sistema di trascrizione fonetica che accompagnava il Questionario. Particolarmente complesso era emerso il quadro relativo alla trascrizione di alcune consonanti del settore “palatale”, per le quali i grafemi (e i foni a essi corrispondenti) p…

Settore L-FIL-LET/12 - Linguistica ItalianaAmong the «Editorial problems» that emerged during the control and organization of the materials coming from the survey campaign of the Atlante Linguistico del Mediterraneo (ALM) Berruto (1971-1973) notes the proliferation and heterogeneity of some graphemic choices made by different field researchers. As they were engaged in a more or less punctual transcription of the answers obtained they had interpreted and solved differently some of the directions provided in the phonetic transcription system that accompanied the Questionnaire. The picture relating to the transcription of some consonants of the palatal sector had emerged as particularly complex since the graphemes (and the corresponding phones) foreseen in the original system (ALM 1959) were insufficient. Not even the 1971 updates meant to improve the representation of some phonetic features emerged from the investigations in the operations of Response reviewing allowed to obtain a clear homogeneous picture regarding the «plosive palatal» consonants. With regard to the phonetic trait under scrutiny I have already had the opportunity to propose a path aiming to the achievement of possible operational solutions. This has taken place in view of the planned simplification / homologation and transcoding phase from the ALM original system to the IPA one - while proceeding from the examination of the Schedoni’s current state with regard to the surveys referring to central-southern Italy Corsica and Sicily (see Matranga 2019). The scope is now to investigate the same phonetic trait as proven in the materials about the surveys carried out by Lirak Dodbiba in the ALM’s three Albanian points.
