Abstract

Canine distemper virus (CDV) belongs to morbillivirus, including measles virus (MeV) and rinderpest virus, which causes serious immunological and neurological disorders in carnivores, including dogs and rhesus monkeys, as recently reported, but their vaccines are highly effective. The attachment glycoprotein hemagglutinin (CDV-H) at the CDV surface utilizes signaling lymphocyte activation molecule (SLAM) and Nectin4 (also called poliovirus-receptor-like-4; PVRL4) as entry receptors. Although fusion models have been proposed, the molecular mechanism of morbillivirus fusion entry is poorly understood. Here, we determined the crystal structure of the globular head domain of CDV-H vaccine strain at 3.2 Å resolution, revealing that CDV-H exhibits a highly tilted homodimeric form with a six-bladed β-propeller fold. While the predicted Nectin4 binding site is well-conserved with that of MeV-H, that of SLAM is similar but partially different, which is expected to contribute to host specificity. Five N-linked sugars covered a broad area of the CDV-H surface to expose receptor binding sites only, supporting the effective production of neutralizing antibodies. These features are common to MeV-H, although the glycosylation sites are completely different. Furthermore, real-time observation using high-speed atomic force microscopy revealed highly mobile features of the CDV-H dimeric head via the connector region. These results suggest that sugarshielded tilted-homodimeric structure and dynamic conformational changes are common characteristics of morbilliviruses and ensure effective fusion entry and vaccination.
Soil climate underpins year effects driving divergent outcomes in semi-arid cropland to grassland restoration
Authors: Mahood Adam , Barnard David , Macdonald Jacob , Green Tim , Erskine Robert 
Published: May 2024

Abstract

Converting croplands to grasslands can restore ecosystem functions and services, but there is uncertainty about why some restoration treatments succeed and others do not. One likely explanation for variation in restoration outcomes is that interannual variation in the drivers of community assembly, or “year effects”, are often overlooked in restoration planning. Existing restoration strategies tailor species compositions of seed mixes according to long-term climate means and hardiness zones. However, individual years typically deviate from average climate norms such that restoration activities may be better informed by recent conditions than by climate averages. We monitored a 109 ha field in northeastern Colorado that was converted from a winter wheat-fallow rotation to native perennial grassland via seeding. The same seed mix was used to seed 6 of 12 120 m strips in 2013 (drier) and 6 in 2014 (wetter). In the strips seeded in 2013, only one native grass and one shrub species from the seed mix established widely, whereas in 2014 all native grasses established. Higher soil moisture preceding seed application was positively associated with perennial grasses, while rhizomatous grasses, shrubs and introduced annuals were associated with other variables. After seeding, high summer soil moisture was positively associated with a rhizomatous C3 grass, while the planted C4 bunchgrasses were negatively associated with high summer soil moisture and positively associated with high fall soil temperatures. We found evidence of facilitatory interactions between grasses and forbs, and antagonistic interactions between native perennial grasses and non-native annuals. Our results suggest that the conditions immediately before and after planting govern community assembly and leave a lasting legacy and should be considered in planning treatments. We suggest composing seed mixes that are tailored to commonly encountered extremes of temperature and moisture availability. Land managers can also use split-seeding or repeated seeding approaches, within or between years as bet-hedging 2 3 strategies. The development of more flexible funding mechanisms could allow for regional go/no-go climate thresholds to avoid wasting resources.

Abstract

Context-aware Neural Machine Translation can potentially enhance automated translation quality through effective modelling of context beyond the sentence level. However, suitable corpora for contextual modelling are still scarce, presenting a significant challenge for the training and evaluation of context-aware systems. To address this challenge, we describe \textsc{tando^+}, a document-level corpus for the under-resourced language pairs Basque-French and Basque-Spanish. We provide a detailed description of this corpus, which is to be shared with the scientific community. The corpus comprises parallel data from diverse domains (literature, subtitles, and news) and incorporates context-level information. Additionally, it provides manually crafted contrastive test sets for Basque-Spanish, designed for comprehensive assessment of gender and register contextual phenomena. Additionally, we train and evaluate sentence-level baseline models and several state-of-the-art contextual variants. Our results and analyses indicate that the corpus is well-suited to train and evaluate context-aware machine translation systems for the two selected under-resourced language pairs.
A Thermodynamic Study on Oxidative Dry Reforming of Ethanol for Syngas Production
Authors: SENAPATI SNIGDHA , Ray Koustuv , Pradhan Narayan Chandra 
Published: May 2024

Abstract

Oxidative dry reforming of ethanol is a promising route to utilize CO2, a greenhouse gas and ethanol, a renewable feedstock in the production of synthesis gas (syngas-a mixture of H2 and CO). It is a feedstock for Fischer-Tropsch (F-T) process to produce synfuels and valuable chemicals. Syngas is mainly produced by dry reforming of methane, but its continuous deployment urges to find an alternative feedstock such as ethanol. The present work aims to simulate syngas production from ethanol focusing on the reduction of carbon formation and energy requirement. Thermodynamic equilibrium analysis for dry reforming and oxidative dry reforming of ethanol are carried out following Gibbs free energy minimization method using Aspen Plus simulation tool. The reaction temperature and feed mole ratio (O2/CO2/ethanol) are varied to obtain equilibrium moles of different products including solid carbon at atmospheric pressure. Syngas yield increases from 1 to 5.2 moles with a suitable ratio of H2/CO when temperature is increased from 500 to 800 0C at CO2/ethanol mole ratio of 1 at atmospheric pressure. The addition of oxygen does not affect syngas production much but drastically reduces carbon formation and the amount of energy requirements. Carbon formation becomes negligible when 0.2 moles O2 in feed stream is added at 775 0C and atmospheric pressure, while in the absence of oxygen 0.392 moles carbon is formed at the otherwise identical operating conditions. At above conditions, addition of 0.2 moles of O2 co-feed can reduce energy requirements of the reformer up to 13.35%.
Retinal sensitivity above macular neovascularization under anti-VEGF therapy in exudative neovascular age-related macular degeneration
Authors: Pauleikhoff Daniel , Pauleikhoff Laurenz , Ziegler Martin , Bachmeier Isabel , Yu Siqing 
Published: May 2024

Abstract

Purpose:
Growth of macular neovascularization (MNV) associated with the development of macular atrophy in some eyes has been observed in neovascular age-related macular degeneration (nAMD) under effective anti-vascular endothelial growth factor (VEGF) therapy. We aimed to evaluate the influence of growing MNV and macular atrophy development on the sensitivity of the overlaying retina.
Methods:
Prospective pilot study on nAMD patients undergoing long-term anti-VEGF therapy (IVAN treatment strategy) that had also undergone microperimetry testing. MNV extension and, if present, associated macular atrophy defined as complete retinal pigment epithelial and outer retina atrophy (cRORA) were identified on OCT volume scans and transposed onto en-face NIR images. Mesopic microperimetry performed at the same visit was superimposed. Retinal sensitivity above the MNV and the surrounding retina was compared, excluding areas of cRORA.
Results:
26 eyes (19 f, 7 m; age 79.3 ± 5.7 y; fu 4.0 ± 1.8 y; 7.4 ± 2.5 inj./y) were classified into “no cRORA” group (n=11) and “cRORA” group (n=15). In the “no cRORA” group, BCVA was significantly higher, and mean retinal sensitivity above the MNV did not differ from the surrounding retina (20.9 ± 2.8 vs. 22.0 ± 2.4, p=.33), while in the “cRORA” group, a lower sensitivity above the MNV was observed (16.2 ± 3.4 vs 19.9 ± 2.0, p=.001).
Conclusion:
In the absence of cRORA, retinal sensitivity above the MNV did not differ significantly from that of the surrounding retina. These results support the hypothesis that MNV itself may not be detrimental if cRORA can be prevented.
