First-order visual interneurons distribute distinct contrast and luminance information across ON and OFF pathways to achieve stable behavior
2022
Source data of the paper Ketkar, Gür, Molina-Obando et al. 2022, eLife. We analyzed the behavioral contribution and physiological response properties of first order interneurons L1, L2 and L3 in the Drosophila melanogaster visual system. Data are sorted by figures and comprise either behavioral measurements of flies walking on an air-cushioned ball while being shown visual stimuli, or in vivo two photon microscopy recordings of L1-L3 calcium responses. Please find all relevant information to use the data in the README file. The code to analyze the data, either written in Matlab or Python, is found at https://github.com/silieslab/Ketkar-Gur-MolinaObando-etal2022

Sensory systems sequentially extract increasingly complex features. ON and OFF pathways, for example, encode increases or decreases of a stimulus from a common input. This ON/OFF pathway split is thought to occur at individual synaptic connections through a sign-inverting synapse in one of the pathways. Here, we show that ON selectivity is a multisynaptic process in the Drosophila visual system. A pharmacogenetics approach demonstrates that both glutamatergic inhibition through GluClα and GABAergic inhibition through Rdl mediate ON responses. Although neurons postsynaptic to the glutamatergic ON pathway input L1 lose all responses in GluClα mutants, they are resistant to a cell-type-specifi…

Lipid-related thiamine deficiency cause mortality of river lampreys (Lampetra fluviatilis) during pre-spawning fasting
2023
Publisher Copyright: © 2023 The Authors River lampreys (Lampetra fluviatilis) were caught in the fall 2014 on entering the River Perhonjoki for spawning and kept at a hatchery until spawning in late spring 2015 to produce larvae for compensatory stockings. Since the lampreys died massively from early February onwards, they were investigated in March and May to clarify the cause of the deaths. The symptoms in lampreys resembled those of lipid-related thiamine (vitamin B1) deficiency of salmonines, called the M74 syndrome in the Baltic Sea area. Because the lipid content of lampreys was known to be high, thiamine concentrations were analyzed in the liver and ovulated unfertilized eggs, and th…
Characterization of the "viable but nonculturable" (VBNC) state in the wine spoilage yeast Brettanomyces.
2012
Although the viable but not culturable (VBNC) state has been studied in detail in bacteria, it has been suggested that maintenance of viability with loss of culturability also exists in eukaryotic cells, such as in the wine spoilage yeast Brettanomyces. To provide conclusive evidence for the existence of a VBNC state in this yeast, we investigated its capacity to become viable and nonculturable after sulfite stress, and its ability to recover culturability after stressor removal. Sulfite addition induced loss of culturability but maintenance of viability. Increasing the medium pH to decrease the concentration of toxic SO(2) allowed yeast cells to become culturable again, thus demonstrating …
Plasticity in Photoperiodism : Drosophila montana Females Have a Life-Long Ability to Switch From Reproduction to Diapause
2022
Photoperiodic reproductive diapause is an essential part of female life cycle in several insect species living on high latitudes, where overwintering in reproductive stage involves high risks for survival and progeny production. The sensitive period (SP), during which photoperiodic cues can trigger the switch from direct development to diapause, can last from a few hours or days after emergence to the entire life span of females. Moreover, in some species, sexually mature females can enter post-reproductive diapause as a response to decreasing day length and/or temperature. We studied the duration of SP for diapause induction and the females’ ability to enter post-reproductive diapause at s…
“The Evils Which Have Arisen in My Country” : Mary Power Lalor and Active Female Landlordism during the Land Agitation

The British journalist and author, Frederic Whyte, reminisced fondly about his childhood trips to County Tipperary, presenting an idealistic image of Mary Frances Power Lalor, one of the most active of Irish landowners during the later Victorian period. peerReviewed
A qualitative study of pre-service teachers’ experienced benefits and concerns of using motivational interaction in practice after a training course
2022
This is a pre-print of a published study: Renko, E., Koski-Jännes, A., Absetz, P. et al. A qualitative study of pre-service teachers’ experienced benefits and concerns of using motivational interaction in practice after a training course. Humanit Soc Sci Commun 9, 458 (2022). https://doi.org/10.1057/s41599-022-01484-y Despite its positive effects on physical activity promotion, motivational style of interaction by health professionals is not easily taken up, as shown by meta-analyses of training courses. The concerns professionals experience for taking up the novel skills remain an open question. Preservice physical education teachers were offered a 16-hour training course on motivational i…
