Sequencing data and normalized counts for tripartite RNAseq of Drosophila, Wolbachia, and SINV virus

Irene Newton
Wolbachia is a maternally transmitted bacterium that manipulates arthropod and nematode biology in myriad ways. The Wolbachia strain colonizing Drosophila melanogaster creates sperm-egg incompatibilities and protects its host against RNA viruses, making it a promising tool for vector control. Despite successful trials using Wolbachia-transfected mosquitoes for Dengue control, knowledge of how Wolbachia and viruses jointly affect insect biology remains limited. Using the Drosophila melanogaster model, transcriptomics and gene expression network analyses revealed pathways with altered...

Experimentally elevated testosterone shortens telomeres across years in a free-living songbird

Britt Heidinger, Samuel Slowiniski, Aubrey Sirman, Nicole Gerlach & Ellen Ketterson
Reproductive investment often comes at a cost to longevity, but the mechanisms that underlie these long-term effects are not well understood. In male vertebrates, elevated testosterone has been shown to increase reproductive success, but simultaneously decrease survival. One factor that may contribute to or serve as a biomarker of these long-term effects of testosterone on longevity is telomeres, which are often positively related to lifespan and have been shown to shorten in response to reproduction....

Modeling Hospital-Wide Extracorporeal Cardiopulmonary Resuscitation: Pros and Cons

Shiksha Joshi, Sandipan Shringi, Manpreet Sira & Maya Guglin
Background We aimed to analyze the potential benefits of implementing a hospital-wide extracorporeal cardiopulmonary resuscitation (ECPR) protocol. Methods We analyzed in-hospital cardiac arrests in a large, academic hospital for two consecutive years. For this model, we assumed that ECPR would be started in all adults, with no upper age limit, who have a full code status. We excluded codes lasting <15 minutes, arrests with asystole as an initial rhythm, and patients with hemorrhagic shock or...

William H. Frick, Ryan D. Mallory, Maya Guglin, Eve Anderson, Erin N. Lushin, Rey P. Vivo, Kashif Saleem & Roopa A. Rao
We present the first reported case of left ventricular assist device (LVAD) pump thrombosis in the setting of the coronavirus pandemic. We describe the clinical features of the case which helped to differentiate coronavirus disease 19 (COVID-19) from LVAD pump thrombosis. The patient is 56-year-old female supported by destination LVAD therapy. She was originally implanted with a HeartMate II device in 2015 and underwent two pump exchanges in 2017 and 2019 for pump thrombosis, despite...

Data from: The relationship between native species richness and exotic species richness or occurrence will always be negative when the total number of species is accounted for in statistical models: A response to Beaury et al.

Ranjan Muthukrishnan
Beaury et al. (2020) attempt to address the scale dependence of evidence for biotic resistance by including environmental covariates that can account for total species richness. However, this approach will incorrectly estimate relationships, driven by the accuracy of the covariates rather than the true relationship between native and non-native species.

Cangrelor: Safe and Effective for Left Ventricular Assist Device Thrombosis

Roopa Rao, Eve Anderson, Mark Jones, Muhamed Safiia & Maya Guglin
Pump thrombosis is a devastating complication of left ventricular assist device implantation as it increases the risk of mortality and morbidity. Early and effective treatment is important to prevent the progression of the clot and to avoid the surgical need for pump exchange or heart transplant. The current strategies of intensifying anticoagulation therapy are not consistently effective and carry significant bleeding risks. Cangrelor is a new pharmacological agent that has been utilized as an antiplatelet...

Information Sharing and Bargaining in Buyer-Seller Networks

Sofia Priazhkina & Frank H. Page
This paper presents a model of strategic buyer-seller networks with information exchange between sellers. Prior to engaging in bargaining with buyers, sellers can share access to buyers for a negotiated transfer. We study how this information exchange affects overall market prices, volumes and welfare, given different initial market conditions and information sharing rules. In markets with homogeneous traders, sharing always increases total trade volume. The market reaches Walrasian trade volume when there are more buyers...

Observational evidence of herbivore-specific associational effects between neighboring conspecifics in natural, dimorphic populations of Datura wrightii

Jay Goldberg, Sonya Sternlieb, Genevieve Pintel & Lynda Delph
Associational effects – in which the vulnerability of a plant to herbivores is influenced by its neighbors – have been widely implicated in mediating plant-herbivore interactions. Studies of associational effects typically focus on interspecific interactions or pest-crop dynamics. However, associational effects may also be important for species with intraspecific variation in defensive traits. In this study, we observed hundreds of Datura wrightii – which exhibits dimorphism in its trichome phenotype – from over 30 dimorphic...

Data from: Non-invasive stratification of non-alcoholic fatty liver disease by whole-transcriptome cell-free mRNA characterization

Naga Chalsani, Shusuke Toden, John Sninsky, Richard Rava, Jerome Braun, Samer Gawrieh, Jiali Zhuang, Michael Nerenberg, Stephen Quake & Tara Maddala
Hepatic fibrosis stage is the most important determinant of outcomes in patients with non-alcoholic fatty liver disease (NAFLD). There is an urgent need for non-invasive tests that can accurately stage fibrosis and determine efficacy of interventions. Here we describe a novel cf-mRNA-Sequencing approach that can accurately and reproducibly profile low levels of circulating mRNAs and evaluate the feasibility of developing a cf-mRNA-based NAFLD fibrosis classifier. Using separate discovery and validation cohorts with biopsy-confirmed NAFLD (n=176...

A Case of HeartMate 3 Outflow Graft Twisting with Extraluminal Thrombosis: Is Computed Tomography Angiography Helpful?

Karim Saleb, Marianna Zagurovskaya, Michael Sekela & Maya Guglin
Twists in the outflow graft of the HeartMateTM 3 device (Abbott) have recently been described as a sporadic, late complication. We present a case with a unique combination of external compression of the HeartMate 3 outflow graft by a surgical scar compounded by thrombus formation in the space between the band relief and the outflow graft with associated twist of the outflow graft and severe flow limitation. Computed tomography angiogram (CTA) of the chest was...

Data from: Nanotransfection-based vasculogenic cell reprogramming drives functional recovery in a mouse model of ischemic stroke

Luke Lemmerman, Maria Balch, Jordan Moore, Diego Alzate-Correa, Maria Rincon-Benavides, Ana Salazar-Puerta, Surya Gnyawali, Hallie Harris, William Lawrence, Lilibeth Ortega-Pineda, Lauren Wilch, Ian Risser, Aidan Maxwell, Silvia Duarte-Sanmiguel, Daniel Dodd, Gina Guio-Vega, Dana McTigue, William Arnold, Shahid Nimjee, Chandan Sen, Savita Khanna, Cameron Rink, Natalia Higuita-Castro & Daniel Gallego-Perez
Ischemic stroke causes vascular and neuronal tissue deficiencies that could lead to significant functional impairment and/or death. Although progenitor-based vasculogenic cell therapies have shown promise as a potential rescue strategy following ischemic stroke, current approaches face major hurdles. Here we used fibroblasts nanotransfected with Etv2, Foxc2, and Fli1 (EFF), to drive reprogramming-based vasculogenesis, intracranially, as a potential therapy for ischemic stroke. Perfusion analyses suggest that intracranial delivery of EFF-nanotransfected fibroblasts led to a dose-dependent increase...

Data from: Signatures of north-eastern expansion and multiple refugia: Genomic phylogeography of the Pine Barrens Treefrog, Hyla andersonii (Anura: Hylidae)

Alexa Warwick, Lisa Barrow, Megan Smith, D. Bruce Means, Alan Lemmon & Emily Lemmon
Range fragmentation poses challenges for species persistence over time and may be caused by both historical and contemporary processes. We combined genomic data, phylogeographic model testing, and paleoclimate niche modeling to infer the evolutionary history of the Pine Barrens Treefrog (Hyla andersonii), a seepage bog specialist, in eastern North America to better understand the historical context of its fragmented distribution. We sampled H. andersonii populations across the three disjunct regions of the species’ range: Alabama/Florida...

Supporting information for: The frequency and topology of pseudoorthologs

Megan Smith & Matthew Hahn
Phylogenetics has long relied on the use of orthologs, or genes related through speciation events, to infer species relationships. However, identifying orthologs is difficult because gene duplication can obscure relationships among genes. Researchers have been particularly concerned with the insidious effects of pseudoorthologs—duplicated genes that are mistaken for orthologs because they are present in a single copy in each sampled species. Because gene tree topologies of pseudoorthologs may differ from the species tree topology, they...
