Acute COVID-19 is associated with altered CD8 T-cells indicative of impaired ability to control Epstein–Barr virus reactivationNARA Subscribed
Increasing evidence suggests that reactivation of latent EBV in patients with COVID-19 may be linked to the development of post-acute sequelae of COVID-19, colloquially known as Long COVID. However, the reason for this co-occurrence of primary infection and reactivation of latent viruses remains elusive. During the first wave of COVID-19, we assessed all major immune cell populations by flow cytometry in a cohort of 61 patient...
The order Albuginales includes the causal agents of white blister rust disease, which affect a wide range of weedy plants, both cultivated and wild. The genus Pustula is one of the five major lineages of white blister rusts identified to date. It causes disease on asterids, the largest group of flowering plants. Pustula is represented by several phylogenetically distinct, host-specific lineages, many of which remain formally u...
Aim The urgency for remote, reliable and scalable biodiversity monitoring amidst mounting human pressures on ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), which can track life underwater and on land. However, we lack a unified methodology to report this sampling effort and a comprehensive overview of PAM coverage to gauge its potential as a global research and monitoring tool. To address this...
Purpose According to the recently implemented organized cervical cancer screening program in Germany, women older than 35 years with negative cytology but persistent high-risk human papilloma virus (hrHPV) infection > 12 months should be referred to colposcopy for further evaluation. This study aimed to present and dissect colposcopic and histopathological findings with particular focus on associated hrHPV genotypes. Methods T...
Stoichiometric mismatch causes a warming‐induced regime shift in experimental plankton communitiesNARA Subscribed
In many ecosystems, consumers respond to warming differently than their resources, sometimes leading to temporal mismatches between seasonal maxima in consumer demand and resource availability. A potentially equally pervasive, but less acknowledged threat to the temporal coherence of consumer‐resource interactions is mismatch in food quality. Many plant and algal communities respond to warming with shifts toward more carbon‐ri...
Thirty years of CMV seroprevalence—a longitudinal analysis in a German university hospitalNARA Subscribed
Human cytomegalovirus (CMV) is a significant cause of morbidity and mortality in patient groups at risk. We have previously shown that the anti-CMV IgG seroprevalence in an urban region of Germany has changed over the last decades. Overall, a decline from 63.7 to 57.25% had been observed between 1988–1997 and 1998–2008 ( p < 0,001). Here, we continuously follow the trends to the most recent decade 2009 to 2018. In a retrospect...
Water temperature and stratification depth independently shift cardinal events during plankton spring successionNARA Subscribed
In deep temperate lakes, the beginning of the growing season is triggered by thermal stratification, which alleviates light limitation of planktonic producers in the surface layer and prevents heat loss to deeper strata. The sequence of subsequent phenological events (phytoplankton spring bloom, grazer peak, clearwater phase) results in part from coupled phytoplankton–grazer interactions. Disentangling the separate, direct eff...
Light supply, plankton biomass, and seston stoichiometry in a gradient of lake mixing depthsNARA Subscribed
We derive from a dynamic model that light availability, phytoplankton density, and the carbon : nutrient ratio of phytoplankton biomass should all be negatively related to mixed surface layer depth, whereas the areal standing stock of phytoplankton should show a unimodal, and total and dissolved nutrients a horizontal or increasing, relationship to mixing depth. These predictions agree closely with data from 65 central Europea...
Performance of sinking and nonsinking phytoplankton taxa in a gradient of mixing depthsNARA Subscribed
According to a recent dynamical model, the depth of a well‐mixed water column should have contrasting effects on the abundances of sinking and nonsinking phytoplankton taxa. Because of increasing light limitation, nonsinking taxa should decline monotonically with increasing mixing depth, and because of sinking loss limitation at low mixing depths, sinking taxa should peak at intermediate mixing depths. Along a gradient of mixi...
