Rationale The head twitch response (HTR) is a spontaneously occurring behavior in mice that is increased in frequency by serotonergic psychedelics. The mouse HTR is often used as a proxy for psychedelic-like drug effects, but limited information is available about sex differences in HTRs evoked by various classes of psychedelics (i.e., phenethylamines, lysergamides, tryptamines). Objective and methods To examine potential sex...
Citizen science’s transformative impact on science, citizen empowerment and socio-political processesNARA Subscribed
Citizen science (CS) can foster transformative impact for science, citizen empowerment and socio-political processes. To unleash this impact, a clearer understanding of its current status and challenges for its development is needed. Using quantitative indicators developed in a collaborative stakeholder process, our study provides a comprehensive overview of the current status of CS in Germany, Austria and Switzerland. Our onl...
The three contiguous National Estuary Programs of southwest Florida, along with partners from six coastal counties, have developed a tidal creek water quality assessment framework to help prioritize natural resource investigations across a large population of tidal creeks between Tampa Bay and Estero Bay, Florida. The assessment framework is based on outcomes of a multidisciplinary study and includes a nutrient based report ca...
Leukocyte Telomere Length in Patients with Multiple Sclerosis and Its Association with Clinical PhenotypesNARA Subscribed
Aging is a significant factor influencing the course of multiple sclerosis (MS). Accelerated telomere attrition is an indicator of premature biological aging and a potential contributor to various chronic diseases, including neurological disorders. However, there is currently a lack of studies focusing on telomere lengths in patients with MS. We measured the average leukocyte telomere length (LTL) in biobanked DNA samples of 4...
Impact of high salinity and the compatible solute glycine betaine on gene expression of Bacillus subtilisNARA Subscribed
Summary The Gram‐positive bacterium Bacillus subtilis is frequently exposed to hyperosmotic conditions. In addition to the induction of genes involved in the accumulation of compatible solutes, high salinity exerts widespread effects on B. subtilis physiology, including changes in cell wall metabolism, induction of an iron limitation response, reduced motility and suppression of sporulation. We performed a combined whole‐trans...
Convergent vomeronasal system reduction in mammals coincides with convergent losses of calcium signalling and odorant‐degrading genesNARA Subscribed
The vomeronasal system (VNS) serves crucial functions for detecting olfactory clues often related to social and sexual behaviour. Intriguingly, two of the main components of the VNS, the vomeronasal organ (VNO) and the accessory olfactory bulb, are regressed in aquatic mammals, several bats and primates, likely due to adaptations to different ecological niches. To detect genomic changes that are associated with the convergent...
Lebenswissenschaften im UmbruchNARA Subscribed
Summary The Gram‐positive bacterium B acillus subtilis encounters nutrient limitations and osmotic stress in its natural soil ecosystem. To ensure survival and sustain growth, highly integrated adaptive responses are required. Here, we investigated the system‐wide response of B . subtilis to different, simultaneously imposed stresses. To address the anticipated complexity of the cellular response networks, we combined chemosta...
The modulator of the general stress response, MgsR, of Bacillus subtilis is subject to multiple and complex control mechanismsNARA Subscribed
Summary The alternative sigma factor σ B is the master regulator of the general stress regulon that comprises approximately 200 genes whose products confer a comprehensive stress resistance to Bacillus subtilis . The characterization of MgsR ( m odulator of the g eneral s tress r esponse) revealed that the activation and induction of σ B are a prerequisite but not sufficient for a full expression of all general stress genes. M...
Summary The general stress response and the decision‐making processes of sporulation initiation are interconnected pathways in the regulatory network of Bacillus subtilis . In a previous study we provided evidence for a mechanism capable of impairing sporulation by σ B ‐dependent induction of spo0E , encoding a phosphatase specifically inactivating the sporulation master regulator Spo0A∼P. Here we show that the σ B promoter (P...
Summary Aromatic organic compounds that are present in the environment can have toxic effects or provide carbon sources for bacteria. We report here the global response of Bacillus subtilis 168 to phenol and catechol using proteome and transcriptome analyses. Phenol induced the HrcA, σ B and CtsR heat‐shock regulons as well as the Spx disulfide stress regulon. Catechol caused the activation of the HrcA and CtsR heat‐shock regu...
