Genomic analysis of three medieval parchments from German monasteries
Abstract In the last two decades there has been growing interest in the analysis of ancient DNA obtained from the parchment used in historic documents. The genetic insight that this data provides makes collections of historic documents an invaluable source for studying the development and spread of historical livestock populations. Additionally, the biological data may provide new information for the historical analysis that could be used to determine the provenance as well as the authenticity of these documents. In this study, we extracted DNA from three medieval parchments that were written in German monasteries in the twelfth century. The source animal of the parchments could be identified as cattle and we compared their genome sequences with those of modern populations that are part of the 1000 Bull Genomes Project. The three animals were found to carry mtDNA haplogroup T3 and show a closer genetic relationship to other historic animals than to modern breeds. We further identified 39 haplotypes and 132 SNPs variants, which are rare ( $$<0.1$$ < 0.1 ) or even non-existent in modern breeds. Finally, the genetic distances between the parchment samples show a putative association with the dates when the documents were written, indicating the usefulness of genetic analysis for provenance research.

Evaluation of transcriptomic changes after photobiomodulation in spinal cord injury
Abstract Spinal cord injury (SCI) is a significant cause of lifelong disability, with no available disease-modifying treatments to promote neuroprotection and axon regeneration after injury. Photobiomodulation (PBM) is a promising therapy which has proven effective at restoring lost function after SCI in pre-clinical models. However, the precise mechanism of action is yet to be determined. Here, we used an in-vivo model of SCI in adult rats that received daily PBM (660 nm, 24 mW/cm2, 1 min) and at three days post-injury, the injured spinal cord segment was harvested and subjected to whole transcriptome sequencing and subsequent pathway analysis (generally applicable gene-set enrichment (GAGE)). Pathway analysis demonstrated 1275 differentially expressed genes (DEGs) after PBM treatment, of which 397 were upregulated and 878 were downregulated. Key pathways were significantly enriched, including 8.6-fold enrichment of “neuron projection morphogenesis” (adjusted p = 8.10 × 10− 14), with upregulation of Notch3, Slit1/Robo2 and Sema3g pathways. Ribosomal and oxidative phosphorylation pathways and NADH dehydrogenase were downregulated, and there was upregulation of ATP-dependent activity, cAMP and calcium signalling pathways. Key genes in apoptotic pathways were downregulated, as were S100 and cyclo-oxygenase components. Together, our study supports the favourable effects of PBM in promoting neuroregeneration and suppressing apoptosis after neurological injury. Further findings from pathway analysis suggest that downregulation of metabolism-associated pathways is a mechanism by which acute post-injury mitochondrial dysfunction may be averted by PBM therapy.

Predictors, patterns, and correlates of moderate-severe psychological distress among New York City College Students during Waves 2–4 of COVID-19
Abstract The COVID-19 pandemic may have exacerbated mental health conditions by introducing and/or modifying stressors, particularly in university populations. We examined longitudinal patterns, time-varying predictors, and contemporaneous correlates of moderate-severe psychological distress (MS-PD) among college students. During 2020–2021, participants completed self-administered questionnaires quarterly (T1 = 562, T2 = 334, T3 = 221, and T4 = 169). MS-PD reflected Kessler-6 scores ≥ 8. At T1 (baseline), most participants were cisgender women [96% vs. 4% transgender/gender non-conforming (TGNC)]. MS-PD prevalence was over 50% at all timepoints. MS-PD predictors included low self-rated health and perceptions of local pandemic control, verbal/physical violence experience, food insecurity, cohabitation dynamics, geographic location, and loneliness. Unique MS-PD correlates encompassed drug use and TGNC identity. Trajectories comprised Persistently (40%), Highly (24% MS-PD twice/thrice), Minimally (15% MS-PD once), and Never (21%) Distressed. Persistently Distressed students had low social support and self-rated health; high food insecurity, drug use, physical/verbal violence experience, need-based financial aid, and TGNC representation; and fluctuating self-rated health amid increasing COVID-19 symptomatology. In this sample, MS-PD prevalence was high, persistent, and associated with financial, behavioral, structural, experiential, and intra- and inter-personal factors. Given its complexity, improving and preserving college students’ mental health necessitates comprehensive, multi-component activities to change adjustable stressors while attenuating the adverse effects of immutable influences.

Temperature dependence of liverwort diversification reveals a cool origin and hot hotspots
Abstract The evolutionary history underlying gradients in species richness is still subject to discussions and understanding the past niche evolution might be crucial in estimating the potential of taxa to adapt to changing environmental conditions. In this study we intend to contribute to elucidation of the evolutionary history of liverwort species richness distributions along elevational gradients at a global scale. For this purpose, we linked a comprehensive data set of genus occurrences on mountains worldwide with a time-calibrated phylogeny of liverworts and estimated mean diversification rates (DivElev) and mean ages (AgeElev) of the respective genera per elevational band. In addition, we reconstructed the ancestral temperature preferences of the genera. We found that diversification rates increase linearly with temperature, and hence decrease with elevation. This pattern is mainly driven by epiphytic genera. In contrast, overall genus age is highest at intermediate elevations where liverwort species richness peaks and decreases towards both ends of the elevational and thermal gradient. Our results further indicate that the ancestral lineages from which the extant liverwort genera descended had a preference for cool and humid habitats. We conclude that the extant liverwort species diversity accumulated over long time under these climatic conditions, which are today prevailing at mid-elevations of the world’s mountains. Subsequently, liverworts expanded their ranges from these temperate areas towards warm (with high diversification rates) and cold regions (with low diversification rates), located in contemporaneous (tropical) lowlands and high mountains, respectively. The conserved preference for temperate climates shared by the majority of liverwort lineages gives reason to the assumption that they will not be able to cope with the conditions induced by rapid climate warming, whereas the current low-elevation radiation may be less affected by climate change.
