Responses and adaptations of collembolan communities (Hexapoda: Collembola) to flooding and hypoxic conditions
2009
Standard ecological methods (pitfall traps, trunk eclectors and soil cores) were used to evaluate collembolan community responses to different flooding intensities. Three sites of a floodplain habitat near Mainz, Germany, with different flooding regimes were investigated. The structures of collembolan communities are markedly different depending on flooding intensity. Sites more affected by flooding are dominated by hygrophilic and hygrotolerant species, whereas the hardwood floodplain is dominated by mesophilic species. The survival strategies of the hygrophilic and hygrotolerant species include egg diapause and passive drifting. The physiological adaptations to hypoxic conditions of sever…
The endangered freshwater pearl mussel Margaritifera margaritifera shows adaptation to a local salmonid host in Finland
2022
1. The freshwater pearl mussel Margaritifera margaritifera (FPM) is an endangered unionid which has a glochidium larva that attaches to the gills of Atlantic salmon Salmo salar or brown trout S. trutta, although some FPM populations have been shown to exclusively attach to only one of these species. The origin of host fish populations may be crucial for conservation actions for this mussel species, but the relative suitability of local (sympatric) and non- local (allopatric) salmonid populations as the hosts for FPM has been studied only rarely. We hypothesised that FPM glochidia would show adaptation to local salmonid strains and, there-fore, that they would be more successful (abundant, l…
AMPA Receptor Auxiliary Proteins of the CKAMP Family
2019
α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors are assembled of four core subunits and several additional interacting proteins. Cystine-knot AMPA receptor-modulating proteins (CKAMPs) constitute a family of four proteins that influence the trafficking, subcellular localization and function of AMPA receptors. The four CKAMP family members CKAMP39/shisa8, CKAMP44/shisa9, CKAMP52/shisa6 and CKAMP59/shisa7 differ in their expression profile and their modulatory influence on AMPA receptor function. In this review, I report about recent findings on the differential roles of CKAMP family members.
Análisis de los motivos para la participación en actividades físicas de personas con y sin discapacidad
2006
Tradicionalmente, la actividad física adaptada ha sido utilizada para conseguir efectos terapéuticos y rehabilitadores en las personas con discapacidad. Actualmente, los educadores relacionados con la actividad física y deporte adaptado pretenden hacer ver a la sociedad en general que las personas con discapacidad pueden practicar actividades físicas y deportivas por las mismas motivaciones que las personas sin discapacidad. Para contribuir a este objetivo, y empleando como marco de referencia la teoría de las metas de logro, hemos analizado las motivaciones de una muestra de 80 personas con discapacidad funcional y otras 80 sin ningún tipo de discapacidad, todas ellas practicantes de activ…
Endocrine effects of sauna bath
2020
Sauna bath brings about numerous acute changes in hormone levels, partly akin to other stressful situations, partly specific for sauna. Norepinephrine increases in those accustomed to sauna bath. Sweating increases the production of antidiuretic hormone, and the renin-angiotensin system becomes activated. Of the anterior pituitary hormones, growth hormone (GH) and prolactin (PRL) secretion is increased. Also β-endorphin has been frequently reported to increase, whereas the responses of ACTH and cortisol are variable, probably depending on the type of sauna exposure. Sperm production decreases in particular in sauna-naïve men, but reduced fertility has not been associated with regular sauna …

Estrategias alternativas para la bioconjugación de ocratoxina A y su aplicación en inmunodiagnóstico alimentario
2020
Ocratoxina A (OTA) es un metabolito secundario producido por hongos del género Aspergillus y Penicillium. Esta micotoxina puede encontrarse en una gran variedad de alimentos, entre los que se encuentran cereales, café o vino. OTA es un potente carcinógeno en roedores, motivo por el que se encuentra clasificado en el grupo 2B (posible carcinógeno para humanos) por la Agencia Internacional de Investigación sobre el Cáncer. Con el objetivo de reducir la exposición de los consumidores a esta micotoxina, la Comisión Europea ha establecido concentraciones máximas en varias matrices alimentarias, siendo este límite de 2 µg/L en el caso de vino y zumo de uva. Entre las diferentes técnicas analítica…
Vuorokaudenajan ja harjoitusjärjestyksen vaikutukset hermostolliseen adaptaatioon, lihasvoimaan ja poikkipinta-alaan yhdistetyssä voima- ja kestävyys…
2014
Rytkönen, Tuomas (2015). Vuorokaudenajan ja harjoitusjärjestyksen vaikutukset hermostolliseen adaptaatioon, lihasvoimaan ja poikkipinta-alaan yhdistetyssä voima- ja kestävyysharjoittelussa. Liikuntabiologian laitos, Jyväskylän yliopisto. Valmennus- ja testausopin pro gradu -työ. 91 s. Monissa liikuntasuoritteissa tarvitaan sekä voimaa (V) että kestävyyttä (K). Yhdistetyssä V+K -harjoittelussa kohtuullinen harjoittelun kokonaisvolyymi on avain siihen, että voiman kehittyminen häiriintyy mahdollisimman vähän kestävyysharjoittelusta. Tässä tutkimuksessa V:aa ja K:ttä harjoitettiin 2–2,5 kertaa viikossa. Yksi aikaa säästävä tapa toteuttaa yhdistettyä V+K -harjoittelua on harjoittaa V:aa ja K:tt…

On personalized adaptation of learning environments
2017
This work is devoted to the development of personalized training systems. A major problem in learning environments is applying the same approach to all students: i.e., teaching materials, time for their mastering, and a training program that is designed in the same way for everyone. Although, each student is individual, has his own skills, ability to assimilate the material, his preferences and other. Recently, recommendation systems, of which the system of personalized learning is a part, have become widespread in the learning environments. On the one hand, this shift is due to mathematical approaches, such as machine learning and data mining, that are used in such systems while, on the ot…
