In eukaryotes, proliferating cell nuclear antigen (PCNA) plays a vital role in the assembly of multiprotein complexes at the replication fork and is essential for cell viability. PCNA from several organisms, including Saccharomyces cerevisiae, has been structurally characterised. However, the structural analyses of PCNA from fungal pathogens are limited. Recently, we have reported that PCNA from the opportunistic fungal pathogen Candida albicans complements the essential functions of ScPCNA in S. cerevisiae. Still, it only partially rescues the loss of ScPCNA when the yeast cells are under genotoxic stress. To understand this further, herein, we have determined the crystal structure of CaPCNA and compared that with the existing structures of other fungal and human PCNA. Our comparative structural and in-solution small-angle X-ray scattering (SAXS) analyses reveal that CaPCNA forms a stable homotrimer, both in crystal and in solution. It displays noticeable structural alterations in the oligomerisation interface, P-loop and hydrophobic pocket regions, suggesting its differential function in a heterologous system and avenues for developing specific therapeutics. DATABASES The PDB and SASBDB accession codes for CaPCNA are 7BUP and SASDHQ9, respectively.Decades of atmospheric nitrogen (N) deposition in the northeastern USA have enhanced this globally important forest carbon (C) sink by relieving N limitation. While many N fertilization experiments found increased forest C storage, the mechanisms driving this response at the ecosystem scale remain uncertain. Following the optimal allocation theory, augmented N availability may reduce belowground C investment by trees to roots and soil symbionts. To test this prediction and its implications on soil biogeochemistry, we constructed C and N budgets for a long-term, whole-watershed N fertilization study at the Fernow Experimental Forest, WV, USA. Nitrogen fertilization increased C storage by shifting C partitioning away from belowground components and towards aboveground woody biomass production. Fertilization also reduced the C cost of N acquisition, allowing for greater C sequestration in vegetation. Despite equal fine litter inputs, the C and N stocks and C N ratio of the upper mineral soil were greater in the fertilized watershed, likely due to reduced decomposition of plant litter. By combining aboveground and belowground data at the watershed scale, this study demonstrates how plant C allocation responses to N additions may result in greater C storage in both vegetation and soil.
To describe the frequency and timing of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody detection in a convenience sample of skilled nursing facility (SNF) residents with and without confirmed SARS-CoV-2 infection.
Retrospective analysis of SNF electronic health records.
Qualitative SARS-CoV-2 antibody test results were available from 81 SNFs in 16 states.
Six hundred and sixty nine SNF residents who underwent both polymerase chain reaction (PCR) and antibody testing for SARS-CoV-2.
Presence of SARS-CoV-2 antibodies following the first positive PCR test for confirmed cases, or first PCR test for non-cases.
Among 397 residents with PCR-confirmed infection, antibodies were detected in 4 of 7 (57.1%) tested within 7-14 days of their first positive PCR test; in 44 of 47 (93.6%) tested within 15-30 days; in 182 of 219 (83.1%) tested within 31-60 days; and in 110 of 124 (88.7%) tested after 60 days. Among 272 PCR negative residents, antibodies were detected in 2 of 9 (22.2%) tested, and that antibodies are most likely to be detected within 15-30 days of diagnosis. That antibodies were detected in a large proportion of residents with no confirmed SARS-CoV-2 infection highlights the complexity of identifying who is infected in real time. Frequent surveillance and diagnostic testing based on low thresholds of clinical suspicion for symptoms and/or exposure will remain critical to inform strategies designed to mitigate outbreaks in SNFs while community SARS-CoV-2 prevalence remains high.The 2nd International DKFZ Conference on Cancer Prevention (CCP2020) organized by the German Cancer Research Center (DKFZ) was held as a virtual event on 17-18 September 2020. The event gathered experts on cancer prevention from around the world with the aim of generating a stimulating interchange of opinions between clinicians and basic researchers working in the field. The talks and posters of the conference fueled exciting discussions and debates about the state of the art of cancer prevention and provided a comprehensive outlook on the many aspects of the field. The program was divided into three main sessions, illustrating the most recent methodological approaches and interventions in primary, secondary and tertiary prevention, enriched by introductory lectures depicting the most relevant aspects of each session. The key concepts covered in this meeting were risk factors, early detection, improving life after cancer, cancer prevention in Europe and personalized prevention. The importance of the latter was expressly highlighted, many presentations emphasizing that in the era of personalized medicine, prevention also needs to be based on the unique genetic, epigenetic, social and behavioral characteristics of the individual to achieve maximal efficacy. In this article, we summarize the key messages emerging from each section, with particular attention on the most important challenges yet to be met in the field of cancer prevention.To better understand the effect of temperature on the growth and nitrate reductase activity (NRA) of Ulva prolifera and their relationships, the effects of five different temperatures (10, 15, 20, 25, and 30°C) were investigated in a laboratory setup. In this study, an optimization in vitro analysis method for Ulva prolifera NRA was developed. link= ubiquitin-Proteasome degradation Under different treatments, the NRA, nitrate concentration, pH, the intracellular nitrate and nitrite concentrations, and the POC/PON were evaluated. The results of the in vitro analysis method showed it was optimal for the NRA assay when the extraction time was 6 min, enzymatic reaction time 30 min, volume of phenazine methosulfate (PMS) solution 50 μL, NADH concentration 0.36 mM, and KNO3 concentration 10 mM. The maximal NRA (NRAmax ) appeared on the 2nd day in the 10, 15, and 20°C (low-temperature) groups and on the 1st day in the 25 and 30°C (high-temperature) groups. link2 The algal growth ended earlier at a high temperature, ending after 5 d at 30 and 25°C and 7 d at 20°C and 9 d at 15°C, and the alga at 10°C had been growing during the incubation period. Ulva prolifera cultivated in a range of 10-20°C had a long growth cycle and the NRA decreased with increasing temperature when exceeded 15°C, a positive correlation between algal growth and NRA was observed. This study supports NRA is a suitable proxy of the effects of temperature changes on the ability of Ulva prolifera to uptake and metabolize nitrogen nutrients.
The evidence on the association between obesity and atrial fibrillation (AF) recurrence was equivocal. We aimed to evaluate the dose-response relationship between body mass index (BMI) and AF recurrence and adverse events.
A systematic literature search was conducted using PubMed, Europe PMC, EBSCO, ProQuest and Cochrane Library. Obesity was defined as BMI ≥28kg/m
. The primary outcome was AF recurrence, and the secondary outcome was adverse events. Adverse events were defined as procedure-related complications and cardio-cerebrovascular events.
There were a total of 52,771 patients from 20 studies. Obesity was associated with higher AF recurrence (Odds ratio [OR] 1.30 [95% confidence interval [CI] 1.16-1.47], P<.001; I
72.7%) and similar rate of adverse events (OR 1.21 [95% CI 0.87-1.67], P=.264; I
23.9%). ubiquitin-Proteasome degradation Meta-regression showed that the association varies by age (coefficient -0.03, P=.024). Meta-analysis of highest versus lowest BMI showed that the highest group had higher AF recurrence (OR 1.37 [95% CI 1.18-1.58], P<.001; I
64.9%) and adverse events (OR 2.02 [95% CI 1.08-3.76], P=.028; I
49.5%). The linear association analysis for AF recurrence was not significant (P=.544). The dose-response relationship for BMI and AF recurrence was nonlinear (p
<0.001), the curve became steeper at 30-35kg/m
. link2 For adverse events, an increase of 1% for every 1kg/m
increase in BMI (OR 1.01 [95% CI 1.00-1.02], P=.001), the relationship was nonlinear (p
=0.001).
Obesity was associated with higher AF recurrence in patients undergoing catheter ablation. High BMI might be associated with a higher risk for adverse events.

A rise in new techniques, and in particular '-omics'-based methods providing large datasets, has led to an increase in potential proteins and pathways implicated in synaptic function and related disorders. Additionally, advancements in imaging techniques have led to the recent discovery of alternative modes of synaptic vesicle recycling. This has resulted in a lack of clarity over the precise role of different pathways in maintaining synaptic function and whether these new pathways are dysfunctional in neurodevelopmental and neurodegenerative disorders. A greater understanding of the molecular detail of pre-synaptic function in health and disease is key to targeting new proteins and pathways for novel treatments and the variety of new techniques currently available provides an ideal opportunity to investigate these functions. This review focuses on techniques to interrogate pre-synaptic function, concentrating mainly on synaptic vesicle recycling. It further examines techniques to determine the underlying molecular mechanism of pre-synaptic dysfunction and discusses methods to identify molecular targets, along with protein-protein interactions and cellular localization. In combination, these techniques will provide an expanding and more complete picture of pre-synaptic function. With the application of recent technological advances, we are able to resolve events with higher spatial and temporal resolution, leading research towards a greater understanding of dysfunction at the presynapse and the role it plays in pathogenicity.
