Polyamines and ripening of photoreceptor outer segments in chicken embryos.

1995

Abstract Polyamines and their related monoacetyl derivatives were studied in rod outer segment (ROS) and cone outer segment (COS) of photoreceptor cells from chick embryo retina during eye development (7th–18th days). Putrescine was found to be necessary, in the second phase of retinogenesis, to sustain both ROS and COS differentiation and, after acetylation, γ-aminobutyric acid synthesis. On the other hand, spermidine and even more spermine intervene in the third phase of development when photoreceptors mature. Moreover, the presence of N1-acetylspermidine already at the 7th day indicates that in the outer segment of photoreceptor cells too, as in the whole retina, putrescine synthesis com…

The influence of backslopping on lactic acid bacteria diversity in tarhana fermentation

2020

Tarhana is produced at batch systems in which the microbiota has changed accordingly to the microbial load from ingredients. In order to stabilize the microbiota, the effects of backslopping carried out under different temperature regimes (25 and 30 °C), pH (3.70 and 4.00) and inoculation rates (5, 10 and 15%) on lactic acid bacteria (LAB) diversity were determined in tarhana dough. LAB and Total Aerobic Mesophilic Bacteria (TAMB) numbers increased in all tarhana dough samples subjected to backslopping. Temperature and pH significantly affected the microbiological diversity of tarhana whereas the different inoculation rates did not. Tarhana dough showed complex tarhana microbiota following …

Ultraviolet camera measurements of passive and explosive (Strombolian) sulphur dioxide emissions at Yasur volcano, Vanuatu

2020

Here, we present the first ultraviolet (UV) camera measurements of sulphur dioxide (SO2) flux from Yasur volcano, Vanuatu, for the period 6–9 July 2018. These data yield the first direct gas-measurement-derived calculations of explosion gas masses at Yasur. Yasur typically exhibits persistent passive gas release interspersed with frequent Strombolian explosions. We used compact forms of the “PiCam” Raspberry Pi UV camera system [1,2] powered through solar panels to collect images. Our daily median SO2 fluxes ranged from 4 to 5.1 kg s−1, with a measurement uncertainty of −12.2% to +14.7%, including errors from the gas cell calibration drift, uncertainties in plume direction and distance, and…

Gold nanoprobe-based detection of human telomerase reverse transcriptase (hTERT) Gene Expression

2015

Human Telomerase Reverse Transcriptase (hTERT) gene is expressed in all types of cancers, and it is considered as unique biomarker for early detection, monitoring and prognosis of different cancers. Routinely, the main techniques for detection of hTERT gene expression are based on enzymatic amplifications which need specified equipments, expert personnel and high cost and time. With regarding to the clinical importance of analysis of hTERT gene expression, we have developed a rapid, simple and low cost method which detects hTERT RNA target in 5 $\mu {\rm l}$ reaction scale using gold nanoprobes. The method is based on the inhibition of nanoparticle aggregation in the presence of ${\rm MgCl}…

Opettajien kokemuksia CLIL-opetuksen eriyttämisestä : käsityksiä, käytänteitä ja haasteita

2012

Tämä laadullisen tapaustutkimuksen ja määrällisen kyselytutkimuksen yhdistävä kaksivaiheinen tutkimus käsittelee eriyttämistä CLIL-opetuksessa. Tutkimuksen tarkoituksena on selvittää (1) alakoulussa englanninkielistä CLIL-opetusta toteuttavien opettajien käsityksiä eriyttämisestä, (2) heidän CLIL-opetuksessa käyttämiään eriyttämiskeinoja sekä (3) heidän kokemiaan eriyttämisen haasteita. Tutkimuksen ensimmäisen vaiheen tavoitteena on laadullisen tapaustutkimuksen avulla lisätä ymmärrystä ja tietoutta eriyttämisestä ilmiönä inklusiivisessa CLIL-opetuksessa ja tulla tietoiseksi erilaisista käytännön eriyttämiskeinoista, joita opettajat voivat työssään hyödyntää. Tutkimuksen toinen vaihe selvit…

CLIL Implementation in Greece : Empirical Findings from 2006 to 2020

2023

Abstract Despite the increasing interest in CLIL in Greece over the past decade, Greek CLIL research is largely absent from international review studies. This systematic review focuses on primary and secondary education, and examines peer-reviewed empirical research on CLIL implementation in Greece from 2006 to 2020. A total of 33 items are reviewed using qualitative Content Analysis. Organized according to commonalities shared by their foci, the reviewed items highlight three main research areas of CLIL implementation in Greece: (1) CLIL project evaluation, (2) CLIL students’ development, and (3) CLIL teachers. The reviewed studies suggest that CLIL implementation in Greece tends to be qua…

Panorama de la enseñanza de lenguas extranjeras en la España moderna

2017

Este capítulo trata de resumir las tendencias que han marcado la enseñanza de las lenguas extranjeras y la formación del profesorado en la España moderna. Esta temática se desarrollará, sin embargo, otra en paralelo: la idea de Europa, el sentido de su proyecto y de su pertenencia. El anclaje entre las dos ideas no es casual. Como defiende Madrid (2001), a partir de la reforma educativa de 1990 la enseñanza de lenguas extranjeras y la formación de nuestro profesorado se adhirió decididamente al proyecto de construcción europea, al que España se había ido aproximando gradualmente y de manera irreversible desde que Adolfo Suárez solicitara en 1977 la adhesión a la Comunidad Económica Europea,…

Role of ghrelin and leptin in the regulation of carbohydrate metabolism. Part I. Ghrelin

2012

Grelina jest polipeptydem wydzielanym przez komórki wydzielnicze błony śluzowej żołądka i jelit, jądro łukowate podwzgórza, a także przez komórki epsilon (e), które znajdują się w obrębie wysp trzustkowych. Grelina odgrywa ważną rolę w utrzymywaniu homeostazy energetycznej organizmu oraz wpływa na wewnątrzwydzielniczą funkcję trzustki i metabolizm glukozy. W regulacji homeostazy glukozy grelina bierze udział poprzez modulację wydzielania isuliny, jak i wrażliwości na insulinę. Wobec różnorodnych biologicznych skutków działania greliny, obecne badania poświęca się potencjalnym możliwościom ich modyfikowania. Dużo uwagi skupiono wokół enzymu zwanego O-acylo transferazą greliny (ghrelin O-acyl…
