Our analyses detected differences in certain movement behaviors (latencies to move during NET), indicating that individuals from fragmented forests are slow explorers in relation to individuals from the continuous forest. We also found shorter tarsi and tails in the fragmented forest population which were attributed to an overall reduction in body size in these populations. Our results suggest that environmental change driven by fragmentation in an urban landscape is causing population differentiation, but we cannot ascribe observed variations to evolutionary processes only, as the differences observed may be explained by other processes too. However, we suggest that phenotypic differences may be aiding this small understory forest specialist to persist in an urban fragmented landscape.Silicon (Si) accumulation is known to alleviate various biotic and abiotic stressors in plants with potential ecological consequences. However, for dicotyledonous plants our understanding of Si variation remains limited. We conducted a comparative experimental study to investigate (1) interspecific variation of foliar Si concentrations across 37 dicotyledonous forbs of temperate grasslands, (2) intraspecific variation in foliar Si concentration in response to soil Si availability, the influence of (3) phylogenetic relatedness, and (4) habitat association to moisture. Foliar Si differed markedly (approx. 70-fold) across the investigated forbs, with some species exhibiting Si accumulation similar to grasses. Foliar Si increased with soil Si availability, but the response varied across species species with higher Si accumulation capacity showed a stronger response, indicating that they did not actively upregulate Si uptake under low soil Si availability. Foliar Si showed a pronounced phylogenetic signal, i.e., closely related species exhibited more similar foliar Si concentrations than distantly related species. Significant differences in foliar Si concentration within closely related species pairs nevertheless support that active Si uptake and associated high Si concentrations has evolved multiple times in forbs. Foliar Si was not higher in species associated with drier habitats, implying that in dicotyledonous forbs of temperate grasslands high foliar Si is not an adaptive trait to withstand drought. Our results demonstrated considerable inter- and intraspecific variation in foliar Si concentration in temperate forbs. This variation should have pervasive, but so far understudied, ecological consequences for community composition and functioning of temperate grasslands under land-use and climate change.
Theophylline has been suggested to have aneuroprotective effect in ischemic stroke; however, results from animal stroke models and clinical trials in humans are controversial. The aim of this study was to assess the effect of theophylline on the cerebral perfusion with multiparametric magnetic resonance imaging (MRI).

The relative cerebral blood flow (rCBF), relative cerebral blood volume (rCBV), and relative mean transit time (rMTT) in the infarct core, penumbra, and unaffected tissue were measured using multi-parametric MRI at baseline and 3‑h follow-up in patients treated with theophylline or placebo as an add-on to thrombolytic therapy.

No significant differences in mean rCBF, rCBV, and rMTT was found in the penumbra and unaffected tissue between the theophylline group and the control group between baseline and 3‑h follow-up. In the infarct core, mean rCBV increased on average by 0.05 in the theophylline group and decreased by 0.14 in the control group (p < 0.04). Mean rCBF and mean rMTT in the infarct core were similar between the two treatment groups.

The results indicate that theophylline does not change the perfusion in potentially salvageable penumbral tissue but only affects the rCBV in the infarct core. In contrast to the penumbra, the infarct core is unlikely to be salvageable, which might explain why theophylline failed in clinical trials.

Care facilities are particularly challenged by the COVID-19 pandemic. Besides others this includes human and structural resources.

This cross-sectional study evaluated the occurrence of infections, psychosocial stress and the different strategies to handle the COVID-19 pandemic in care facilities.

Data collection took place in 7care facilities in Baden-Württemberg, Germany between 17 July and 25 August 2020. This included aSARS-CoV‑2 PCR and antibody testing and a questionnaire for residents and staff. Care facilities were questioned on interventions and preventive measures taken.

Out of 829 SARS-CoV‑2 PCR tests all remained negative. Only2 asymptomatic subjects had detectable SARS-CoV‑2 antibodies. All subjects (n = 6) with ahistory of positive PCR had no detectable antibodies. Healthcare workers were mainly worried about infecting family, friends and especially residents (54.4%) with less fear to infect themselves (27.2%). Individual stress caused by the COVID-19 pandemic 17.1% exhaustion, 16% financial burden and 13.1% sleeping disorders. Coping strategies included amoderate increase of harmful behavior (+3.3% alcohol, +4.3% nicotine). This was relevantly more important in staff aged under 35years (+13% alcohol, +12.7% nicotine). Women reported a2.4% increased use of medication, 49.8% of respondents reduced their social contacts, 76.8% changed their individual hygiene behavior. selleck chemical Care facilities felt prepared to alimited extent for the challenges faced by the pandemic.

Even with a low prevalence of infections at the time of the survey the COVID-19 pandemic challenged care facilities at multiple levels. This should result in better preventive management and coping strategies.
