Insights into the diversity and survival strategies of soil bacterial isolates from the Atacama Desert
The Atacama Desert, the driest, with the highest radiation, and one of the most ancient deserts in the world, is a hostile environment for life. We have a collection of 74 unique bacterial isolates after cultivation and confirmation by 16S rRNA gene sequencing. Pigmentation, biofilm formation, antimicrobial production against Escherichia coli MG1655 and Staphylococcus aureus HG003, and antibiotic resistance were assessed on these isolates. We found that approximately a third of the colonies produced pigments, 80% of isolates formed biofilms, many isolates produce growth inhibiting activities against E. coli and/or S. aureus, and many were resistant to antibiotics. The functional characterization of these isolates gives us insight into the adaptive bacterial strategies in harsh environments and enables us to learn about their possible use in agriculture, healthcare, or biotechnology
Taking ELF off the shelf: Developing HE students' speaking skills through a focus on English as a lingua franca
This paper explores how principles derived from English as a lingua franca (ELF) research (e.g. accommodation, strategic competence) can provide insights into the speaking demands of group work in Anglophone EMI settings which includes native speakers as well as non-native speakers. The paper maps data gathered through interviews with first year undergraduate students against Mercer et al.’s (2017) oracy framework. It shows that students draw on a combination of linguistic, cognitive, physical and social & emotional skills, many of which align with ELF principles.
However, current frameworks of support for speaking demands in HE (EAP and academic skills) lack focus on dialogic speaking, pay little heed to ELF findings and cater for native speakers and non-native speakers separately despite their needs being similar. The paper argues that a focus on ELF can contribute to the development of speaking support which sits at the centre of students’ academic journey and encourages better interactions between native and non-native speakers
Prognostic model to predict postoperative acute kidney injury in patients undergoing major gastrointestinal surgery based on a national prospective observational cohort study.
Background: Acute illness, existing co-morbidities and surgical stress response can all contribute to postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. The aim of this study was prospectively to develop a pragmatic prognostic model to stratify patients according to risk of developing AKI after major gastrointestinal surgery. Methods: This prospective multicentre cohort study included consecutive adults undergoing elective or emergency gastrointestinal resection, liver resection or stoma reversal in 2-week blocks over a continuous 3-month period. The primary outcome was the rate of AKI within 7 days of surgery. Bootstrap stability was used to select clinically plausible risk factors into the model. Internal model validation was carried out by bootstrap validation. Results: A total of 4544 patients were included across 173 centres in the UK and Ireland. The overall rate of AKI was 14·2 per cent (646 of 4544) and the 30-day mortality rate was 1·8 per cent (84 of 4544). Stage 1 AKI was significantly associated with 30-day mortality (unadjusted odds ratio 7·61, 95 per cent c.i. 4·49 to 12·90; P < 0·001), with increasing odds of death with each AKI stage. Six variables were selected for inclusion in the prognostic model: age, sex, ASA grade, preoperative estimated glomerular filtration rate, planned open surgery and preoperative use of either an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker. Internal validation demonstrated good model discrimination (c-statistic 0·65). Discussion: Following major gastrointestinal surgery, AKI occurred in one in seven patients. This preoperative prognostic model identified patients at high risk of postoperative AKI. Validation in an independent data set is required to ensure generalizability
Satori- Literary Visual Arts Magazine
Satori is Winona State University’s annual journal of the arts. Founded in 1970, “satori” is Japanese for “enlightenment, awakening, comprehension, and understanding.” Our journal attempts to reflect these values in our campus community.
Every year, students from across campus are invited to submit their fiction, poetry, creative nonfiction, and artistic works. This presentation will give a behind-the-scenes look at the production process of this year\u27s magazine including editing, design, and printing
The 'Neighbourhood Effect': A multidisciplinary assessment of the case for farmer co-ordination in agri-environmental programmes
Blood meal metabarcoding of the argasid tick (Ornithodoros turicata Dugès) reveals extensive vector‐host associations
Abstract Molecular methods to understand host feeding patterns of arthropod vectors are critical to assess exposure risk to vector‐borne disease and unveil complex ecological interactions. We build on our prior work discovering the utility of PCR‐Sanger sequencing blood meal analysis that work well for soft ticks (Acari: Argasidae), unlike for hard ticks (Acari: Ixodidae), thanks to their unique physiology that retains prior blood meals for years. Here, we apply blood meal metabarcoding using amplicon deep sequencing to identify multiple host species in individual Ornithodoros turicata soft ticks collected from two natural areas in Texas, United States. Of 788 collected O. turicata, 394 were evaluated for blood meal source via metabarcoding, revealing 27 different vertebrate hosts (17 mammals, five birds, one reptile, and four amphibians) fed upon by 274 soft ticks. Information on multiple hosts was derived from 167 individual O. turicata (61%). Metabarcoding revealed mixed vertebrate blood meals in O. turicata while same specimens yielded only one vertebrate species using Sanger sequencing. These data reveal wide host range of O. turicata and demonstrate the value of blood meal metabarcoding for understanding the ecology for known and potential tick‐borne pathogens circulating among humans, domestic animals, and wildlife such as relapsing fever caused by Borrelia turicatae. Our results also document evidence of prior feeding on wild pig from an off‐host soft tick for the first time in North America; a critical observation in the context of enzootic transmission of African swine fever virus if it were introduced to the US. This research enhances our understanding of vector‐host associations and offers a promising perspective for biodiversity monitoring and disease control strategies
Cave microbial community composition in oceanic islands: disentangling the effect of different colored mats in diversity patterns of Azorean lava caves
Processes determining diversity and composition of bacterial communities in island volcanic caves are still poorly understood. Here, we characterized colored microbial mats in 14 volcanic caves from two oceanic islands of the Azores using 16S rRNA gene sequences. Factors determining community diversity (α) and composition (β) were explored, namely colored mats, caves and islands, as well as environmental and chemical characteristics of caves. Additive partitioning of diversity using OTU occurrence showed a greater influence of β-diversity between islands and caves that may relate to differences in rare OTUs (singletons and doubletons) across scales. In contrast, Shannon diversity partitioning revealed the importance of the lowest hierarchical level (α diversity, colored mat), suggesting a dominance of cosmopolitan OTUs (\u3e1%) in most samples. Cosmopolitan OTUs included members involved in nitrogen cycling, supporting the importance of this process in Azorean caves. Environmental and chemical conditions in caves did not show any significant relationship to OTU diversity and composition. The absence of clear differences between mat colors and across scales may be explained by (1) the geological youth of the cave system (cave communities have not had enough time to diverge) or/and (2) community convergence, as the result of selection pressure in extreme environments
