Phenotypic Buffering in a Monogenean: Canalization and Developmental Stability in Shape and Size of the Haptoral Anchors of Ligophorus cephali (Monog…

2015

Phenotypic variation results from the balance between sources of variation and counteracting regulatory mechanisms. Canalization and developmental stability are two such mechanisms, acting at two different levels of regulation. The issue of whether or not they act concurrently as a common developmental buffering capacity has been subject to debate. We used geometric morphometrics to quantify the mechanisms that guarantee phenotypic constancy in the haptoral anchors of Ligophorus cephali. Canalization and developmental stability were appraised by estimating inter- and intra-individual variation, respectively, in size and shape of dorsal and ventral anchors. The latter variation was estimated…

Tides in the Last Interglacial: insights from notch geometry and palaeo tidal models in Bonaire, Netherland Antilles

2017

Abstract The study of past sea levels relies largely on the interpretation of sea-level indicators. Palaeo tidal notches are considered as one of the most precise sea-level indicators as their formation is closely tied to the local tidal range. We present geometric measurements of modern and palaeo (Marine Isotope Stage (MIS) 5e) tidal notches on Bonaire (southern Caribbean Sea) and results from two tidal simulations, using the present-day bathymetry and a palaeo-bathymetry. We use these two tools to investigate changes in the tidal range since MIS 5e. Our models show that the tidal range changes most significantly in shallow areas, whereas both, notch geometry and models results, suggest t…

Estudio de los polimorfismos en los genes del Citocromo P450 (CYP1A1, CYP2E1 Y CYP3A4), de la Quinona Oxoreductasa (NQO1), del Glutation S-Transferas…

2013

Se ha estudiado la posible asociación de factores genéticos y la predisposición de padecer leucemias y síndromes mielodisplásicos tras tratamiento antineoplásico. Estos factores genéticos se les suponen relacionados con los genes codificantes de los enzimas que degradan los quimioterápicos y cancerígenos. Por otro parte, se ha analizado el valor pronóstico de los polimorfismos de estos genes en las leucemias mieloides agudas de novo, dado que la mayor o menor actividad de los enzimas que intervienen en la metabolización de quimioterápicos repercute sobre la eficacia del tratamiento administrado y, por tanto, en la duración de la remisión hematológica ulterior. We have studied the possible a…

Indications of polymorphism in the behaviour and morphology of burbot (Lota lota) in a European lake

2022

AbstractIn this study, polymorphism in behaviour, morphology, and stable isotope signatures of burbot from Lake Southern Konnevesi, Finland, Europe, was examined. First, local knowledge was collected on exceptional polymorphism of the spawning behaviour and morphology of burbot. These phenomena were then studied based on catch samples. Interviews and catch sample analyses suggested two morphs of burbot: one morph spawning in late February in the littoral zone and other in late March, in deep profundal, depths of about 30 m. Fish caught from the profundal zone had higher average proportional somatic body weights and wider heads than those caught from the littoral spawning sites in February. …

Audiovisual processing of Chinese characters elicits suppression and congruency effects in MEG

2019

Learning to associate written letters/characters with speech sounds is crucial for reading acquisition. Most previous studies have focused on audiovisual integration in alphabetic languages. Less is known about logographic languages such as Chinese characters, which map onto mostly syllable-based morphemes in the spoken language. Here we investigated how long-term exposure to native language affects the underlying neural mechanisms of audiovisual integration in a logographic language using magnetoencephalography (MEG). MEG sensor and source data from 12 adult native Chinese speakers and a control group of 13 adult Finnish speakers were analyzed for audiovisual suppression (bimodal responses…

Attiecība starp varu un cilvēcību F. Kafkas „Metamorfoze”: interpretēta japāņu manga

2016

Bakalaura darba tēma ir Franca Kafkas romānā „Metamorfoze” atrodamu varas attiecību interpretācija un analīze japāņu manga medijos, balstoties uz Bjorna Krausa un Edvarda Šila varas teorijām. Darbā tika izstrādāts salīdzinošais multimediju pētījums, kura mērķis ir pierādīt un aprakstīt attiecību starp cilvēcību un varu Kafkas darbā, kā arī identificēt kā šī attiecība tiek parādīta „Metamorfozes” ietekmētajās darbos.Pētījuma rezultāti rāda, ka „Metamorfozē” un analizētājās manga eksistē iekšējais, identitātes varas konflikts un ārējais, sabiedriskais varas konflikts starp cilvēci un tās antitēzi., kurā cilvēcība līmenis korelē ar varas līmeni. Noslēgumā tika secināts, ka gan oriģinālais vara…

Aplicaciones de la citología exfoliativa en el diagnóstico del cáncer oral

2004

La citología exfoliativa es una técnica sencilla, no agresiva y bien aceptada por los pacientes, por lo que podría ser útil en el diagnóstico precoz del cáncer oral. Sin embargo, su utilización como método diagnóstico de atipias epiteliales y especialmente del carcinoma oral de células escamosas ha perdido importancia, sobre todo debido a su baja sensibilidad representada por el elevado número de resultados falsos negativos. Se atribuye esta baja sensibilidad a diversos factores, entre ellos: toma inadecuada de la muestra, error en la técnica e interpretación subjetiva de los hallazgos citológicos. Afortunadamente, en los últimos tiempos, el desarrollo del análisis cuantitativo, la citomorf…

Kadmiumaltistuksen havaitseminen Hydropsyche pellucidula -vesiperhostoukilla (Trichoptera: Hydropsychidae) hyperspektrikuvantamisen ja kidusvaurioide…

2017

Metallipäästöt aiheuttavat vesistöissä eliöyhteisöille monenlaisia haittavaikutuksia, joita voidaan tutkia bioindikaattori- eli ilmentäjälajimenetelmin. Vesiperhostoukkia (Trichoptera) on käytetty virtavesien metallisaastumisen indikaattoreina, sillä ne kestävät metallialtistusta suhteellisen hyvin, mutta altistuksen seurauksena toukilla voi esiintyä morfologisia muutoksia, kuten kidusvaurioita tai pintakudoksen tummumista. Koska toisaalta vierasaineiden kudospitoisuusmittaus on usein työlästä ja toisaalta rakenteellisten muutosten arviointi altis subjektiiviselle harhalle, tavoitteenani oli kehittää objektiivinen ja kustannustehokas tapa selvittää metallialtistusta ja sen vaikutuksia pohja…

Izmaiņas augsta un vidēja riska gēnos gados jauniem melanomas pacientiem

2016

Melanoma ir ļaundabīgs ādas audzējs, kas attīstās vides un gēnu mijiedarbības rezultātā. Bakalaura darba mērķis bija izvērtēt izmaiņas augsta un vidēja riska gēnos melanomas pacientiem ar vairākiem primāriem audzējiem un gados jauniem (līdz 40 gadu vecumam) melanomas pacientiem Latvijā. Analīzē tika iekļauti seši pacienti ar vairākām primārām melanomām un 67 gados jauni melanomas pacienti. Tika izanalizēti pieci augsta (CDKN2A, CDK4, BAP1, POT1, TERT) un divi vidēja (MITF, MC1R) melanomas riska gēni. Atrastas trīs dažādas izmaiņas POT1 gēnā, no kurām viena ir jauna līdz šim neaprakstīta izmaiņa, viens rets MITF, divi CDKN2A un 8 dažādi MC1R gēnu polimorfismi. Izmaiņas BAP1, POT1 un CDK4 gēn…
