Puumala- ja lehmärokkoviruksen vaikutus metsämyyrän (Myodes glareolus) metaboliaan
2012
Taudinaiheuttajat, kuten virukset ovat usein haitallisia isäntälajilleen. Virusinfektiot voivat heikentää mm. isäntälajinsa lisääntymistä ja selviytymistä, vaikka ne eivät aiheuttaisikaan näkyviä oireita isäntälajeilleen. Jyrsijöiden yksi yleisimmistä viruksista on hantaviruksiin kuuluva Puumala-virus, jonka isäntälaji on metsämyyrä (Myodes glareolus). Hantavirukset ovat RNA-viruksia ja ne leviävät tehokkaasti tiheissä myyräkannoissa. Puumala-virus voi levitä metsämyyristä myös ihmisiin hengitysteiden kautta aiheuttaen myyräkuumetta. Puumala-viruksen ohella metsämyyristä on löydetty myös lehmärokkovirusta, joka on DNA-virus. Lehmärokkoviruksen tiedetään vaikuttavan heikentävästi metsämyyrie…
Ķermeņa estētika Lenijas Rifenštāles filmā “Zilā gaisma
2017
Lenija Rīfenštāle ir viena no ievērojamākām kinematogrāfistiem Vācijas vēsturē. Šo režisori pazīst visa pasaule, tomēr, dēļ viņas ciešas sadarbības ar Hitleru, viņas filmas nav viennozīmīgas. Bieži tās tiek uztvertas kā nacionālsociālisma himna un apstrīdētas, taču tiek atzīta šo filmu iespaidīga estētika, kas izpaustas arī viņas citās , ar nacionālsociālismu nesaistītās filmās. Šī bakalaura darba tēma ir ķermeņa attēlojums Rīfenštāles filmā „Zilā gaisma”(1932). Ir izskatīta arī citu režijas aspektu ietekme uz ķermeņa estētiku. „Zilā gaisma” ir pirmais režijas darbs, kas tika producēts pirms režisores iepazīšanas ar Hitleru, kas ļauj izslēgt viņa ietekmi un uztvert darbu kā Rīfenštāles pers…
Absence of Sex Differential Plasticity to Light Availability during Seed Maturation in Geranium sylvaticum
2015
Sex-differential plasticity (SDP) hypothesis suggests that since hermaphrodites gain fitness through both pollen and seed production they may have evolved a higher degree of plasticity in their reproductive strategy compared to females which achieve fitness only through seed production. SDP may explain the difference in seed production observed between sexes in gynodioecious species in response to resource (nutrients or water) availability. In harsh environments, hermaphrodites decrease seed production whereas females keep it relatively similar regardless of the environmental conditions. Light availability can be also a limiting resource and thus could theoretically affect differently femal…

The effects of Borrelia infection on its wintering rodent host
2022
AbstractIn seasonal environments, appropriate adaptations are crucial for organisms to maximize their fitness. For instance, in many species, the immune function has been noticed to decrease during winter, which is assumed to be an adaptation to the season’s limited food availability. Consequences of an infection on the health and survival of the host organism could thus be more severe in winter than in summer. Here, we experimentally investigated the effect of a zoonotic, endemic pathogen, Borrelia afzelii infection on the survival and body condition in its host, the bank vole (Myodes glareolus), during late autumn–early winter under semi-natural field conditions in 11 large outdoor enclos…

Yeast–yeast interactions revealed by aromatic profile analysis of Sauvignon Blanc wine fermented by single or co-culture of non-Saccharomyces and Sac…
2012
International audience; There has been increasing interest in the use of selected non-Saccharomyces yeasts in co-culture with Saccharomyces cerevisiae. The main reason is that the multistarter fermentation process is thought to simulate indigenous fermentation, thus increasing wine aroma complexity while avoiding the risks linked to natural fermentation. However, multistarter fermentation is characterised by complex and largely unknown interactions between yeasts. Consequently the resulting wine quality is rather unpredictable. In order to better understand the interactions that take place between non-Saccharomyces and Saccharomyces yeasts during alcoholic fermentation, we analysed the vola…
Population sex-ratio affecting behavior and physiology of overwintering bank voles (Myodes glareolus)
2016
Many boreal rodents are territorial during the breeding season but during winter become social and aggregate for more energy efficient thermoregulation. Communal winter nesting and social interactions are considered to play an important role for the winter survival of these species, yet the topic is relatively little explored. Females are suggested to be the initiators of winter aggregations and sometimes reported to survive better than males. This could be due to the higher social tolerance observed in overwintering females than males. Hormonal status could also affect winter behavior and survival. For instance, chronic stress can have a negative effect on survival, whereas high gonadal ho…
Lipidomic profiling identifies signatures of metabolic risk
2020
Background: Metabolic syndrome (MetS), the clustering of metabolic risk factors, is associated with cardiovascular disease risk. We sought to determine if dysregulation of the lipidome may contribute to metabolic risk factors. Methods: We measured 154 circulating lipid species in 658 participants from the Framingham Heart Study (FHS) using liquid chromatography-tandem mass spectrometry and tested for associations with obesity, dysglycemia, and dyslipidemia. Independent external validation was sought in three independent cohorts. Follow-up data from the FHS were used to test for lipid metabolites associated with longitudinal changes in metabolic risk factors. Results: Thirty-nine lipids were…
