Oxytocin reduces romantic rejection-induced pain in online speed-dating as revealed by decreased frontal-midline theta oscillations
2021
Abstract Background Romantic rejection is an emotionally distressful experience profoundly affecting life, possibly leading to mental illness or suicide. Oxytocin (OT) is a neuropeptide widely implicated in reducing physical pain and negative emotions; however, whether OT has an effect on reducing intense social pain (e.g., romantic rejection) remains unknown. Here, we tested the effect of OT on social pain and investigated its role in the outcome evaluation phase of social decision-making. Methods Electroencephalographic recordings were obtained between August 2nd and October 20th, 2020 in Shenzhen University from 61 healthy participants in a double-blind, placebo-controlled study with a b…
Thyrotropin Receptor Blocking Antibodies.
2018
AbstractAutoantibodies (Ab) against the thyroid-stimulating hormone receptor (TSHR) are frequently found in autoimmune thyroid disease (AITD). Autoantibodies to the TSHR (anti-TSHR-Ab) may mimic or block the action of TSH or be functionally neutral. Measurement of anti-TSHR-Ab can be done either via competitive-binding immunoassays or with functional cell-based bioassays. Antibody-binding assays do not assess anti-TSHR-Ab functionality, but rather measure the concentration of total anti-TSHR binding activity. In contrast, functional cell-based bioassays indicate whether anti-TSHR-Ab have stimulatory or blocking activity. Historically bioassays for anti-TSHR-Ab were research tools and were u…
"Chancen von Tschernobyl" : Ulrich Beckin riskikonsepti näkökulmana länsisaksalaiseen ydinvoimadebattiin 1986
2008
Työni käsittelee vuoden 1986 Tshernobylin ydinvoimalaonnettomuutta seurannutta, ydinvoiman hyväksyttävyyttä koskenutta keskustelua Länsi-Saksassa. Lähestymistapani mukaisesti hahmotan ydinvoimadebattia riski-ilmiön käsittelynä ja käsitteellistämisenä. Näkökulmani kiistan seuraamiseen on Ulrich Beckin Riskogesellschaft; Auf dem Weg in eine andere Moderne - teoksen näkökulma modernisaatioriskeistä poliittisiin ja taloudellisiin kerrannaisvaikutuksiin yltävinä, pitkälle tarkoittamattomina ilmiöinä. Aineiston tulkinnalla analysoin riskin poliittista arviointia ja käsitteellistämistä siitä lähtökohdasta, että uhkaava riski on merkitykseltään tyhjä ja vasta sen poliittinen ja kielellinen määrittä…
Role of volatile and contact pheromones in the mating behaviour of Bagrada hilaris (Heteroptera: Pentatomidae)
2008
Volatiles and contact pheromones involved in the mating behaviour of the Painted bug, Bagrada hilaris Burmeister (Het- eroptera: Pentatomidae), were investigated in behavioural and chemical experiments. Vertical open Y-shaped olfactometer bioassays showed that odour from males attract females but not males, while that from females did not attract either gender. Adult females were also attracted by hexane extracts of volatile compounds collected from males. In open arena bioassays, males displayed the characteristic steps of courtship behaviour in the presence of virgin females. Such courtship behaviour was displayed in the presence of females killed by freezing, but not in the presence of f…
Nuorten miesten kirjeitse ohjailemat seurustelusuhteet 1800-luvun lopun sisäsuomalaisella maaseudulla
2014
Artikkelissa tarkastellaan 1800-luvun Keuruun käräjäkunnassa, sisäsuomalaisella maaseudulla eläneiden nuorten miesten ja naisten seurustelusuhteiden kehittymistä kohti avioliittoa ja sitä, kuinka tälle tielle alkoi kasautua ongelmia. Tutkimuksen ensisijaisena lähdeaineistona ovat miesten seurustelusuhteiden aikana kumppaneilleen lähettämät intiimit yksityiskirjeet (12 kappaletta), jotka naiset olivat tuoneet aviottoman lapsen elatusoikeudenkäynteihin todisteeksi suhteen aikaisesta seksuaalisesta kanssakäymisestä. Artikkeli sijoittuu kansanihmisten kirjoittamia tekstejä tarkastelevaan monitieteiseen historiantutkimuksen alaan. Artikkelissa esitetään, että kirjeet kirjoittaneet miehet pyrkivä…
Strength of sexual and postmating prezygotic barriers varies between sympatric populations with different histories and species abundances
2019
The impact of different reproductive barriers on species or population isolation may vary in different stages of speciation depending on evolutionary forces acting within species and through species’ interactions. Genetic incompatibilities between interacting species are expected to reinforce prezygotic barriers in sympatric populations and lead to cascade reinforcement between conspecific populations living within and outside the areas of sympatry. We tested these predictions and studied whether and how the strength and target of reinforcement between Drosophila montana and Drosophila flavomontana vary between sympatric populations with different histories and species abundances. All barri…
Sexual selection on song and cuticular hydrocarbons in two distinct populations of Drosophila montana
2011
Sexual selection has the potential to contribute to population divergence and speciation. Most studies of sexual selection in Drosophila have concentrated on a single signaling modality, usually either courtship song or cuticular hydrocarbons (CHCs), which can act as contact pheromones. We have examined the relationship between both signal types and reproductive success using F1–3 offspring of wild- collected flies, raised in the lab. We used two populations of the Holarctic species Drosophila montana that represent different phylogeographic clades that have been separate for ca. 0.5 million years (MY), and differ to some extent in both traits. Here, we characterize the nature and identify …
