Data from: Experimental and statistical reevaluation provides no evidence for Drosophila courtship song rhythms

David L. Stern, Jan Clemens, Philip Coen, Adam J. Calhoun, John B. Hogenesch, Ben J. Arthur & Mala Murthy
From 1980 to 1992, a series of influential papers reported on the discovery, genetics, and evolution of a periodic cycling of the interval between Drosophila male courtship song pulses. The molecular mechanisms underlying this periodicity were never described. To reinitiate investigation of this phenomenon, we previously performed automated segmentation of songs but failed to detect the proposed rhythm [Arthur BJ, et al. (2013) BMC Biol 11:11; Stern DL (2014) BMC Biol 12:38]. Kyriacou et al....

Inhibition of Cdc42 activity extends lifespan and decreases circulating inflammatory cytokines in aged female C57BL/6 mice

Maria Carolina Florian, Hanna Leins, Michael Gobs, Yang Han, Gina Marka, Karin Soller, Angelika Vollmer, Vadim Sakk, Kalpana J. Nattamai, Ahmad Rayes, Xueheng Zhao, Kenneth Setchell, Medhanie Mulaw, Wolfgang Wagner, Yi Zheng & Hartmut Geiger
Cdc42 is a small RhoGTPase regulating multiple functions in eukaryotic cells. The activity of Cdc42 is significantly elevated in several tissues of aged mice, while the Cdc42 gain-of-activity mouse model presents with a pre-mature aging-like phenotype and with decreased lifespan. These data suggest a causal connection between elevated activity of Cdc42, aging and reduced lifespan. Here, we demonstrate that systemic treatment of aged (75-week old) female C57BL/6 mice with a Cdc42 activity specific inhibitor (CASIN)...

Data from: Cannabis analgesia in chronic neuropathic pain is associated with altered brain connectivity

Libat Weizman, Lior Dayan, Silviu Brill, Hadas Nahman-Averbuch, Talma Hendler, Giris Jacob & Haggai Sharon
Objective: The purpose of this study was to characterize the functional brain changes involved in THC modulation of chronic neuropathic pain. Methods: Fifteen patients with chronic radicular neuropathic pain participated in a randomized, double-blind, placebo-controlled trial employing a counterbalanced, within-subjects design. Pain assessments and functional resting state brain scans were performed at baseline and after sublingual THC administration. We examined functional connectivity of the anterior cingulate cortex (ACC) and pain related network dynamics using graph...

Data from: Identification of children with anaphylaxis at low risk of receiving acute inpatient therapies

Timothy E. Dribin, Kenneth A. Michelson, Michael C. Monuteaux, Anne M. Stack, Karen S. Farbman, Lynda C. Schneider & Mark I. Neuman
Objective: Opportunity exists to reduce unnecessary hospitalizations for children with anaphylaxis given wide variation in admission rates across U.S. emergency departments (EDs). We sought to identify children hospitalized with anaphylaxis at low risk of receiving epinephrine and other acute inpatient therapies, as these patients may be candidates for ED discharge rather than inpatient hospitalization. Methods: We conducted a single-center retrospective cohort study of children 1–21 years of age hospitalized with anaphylaxis from 2009 to 2016....

Data from: Cardiac and skeletal muscle effects in the randomized HOPE-Duchenne trial

Michael Taylor, John Jefferies, Barry Byrne, Joao Lima, Bharath Ambale-Venkatesh, Mohammad R. Ostovaneh, Raj Makkar, Bryan Goldstein, Rachel Ruckdeschel Smith, James Fudge, Konstantinos Malliaras, Brian Fedor, Jeff Rudy, Janice M. Pogoda, Linda Marbán, Deborah D. Ascheim, Eduardo Marbán & Ronald G. Victor
Objective: To assess the feasibility, safety, and efficacy of intracoronary allogeneic cardiosphere-derived cells (CAP-1002) in patients with Duchenne muscular dystrophy (DMD). Methods: The Halt Cardiomyopathy Progression (HOPE)-Duchenne trial is a phase I/II, randomized, controlled, open-label trial (NCT02485938). Patients with DMD >12 years old, with substantial myocardial fibrosis, were randomized (1:1) to usual care (control) or global intracoronary infusion of CAP-1002 (75 million cells). Participants were enrolled at 3 US medical centers between January and August...

Data from: Multivariate analysis of genotype-phenotype association

Philipp Mitteroecker, James M. Cheverud & Mihaela Pavlicev
With the advent of modern imaging and measurement technology, complex phenotypes are increasingly represented by large numbers of measurements, which may not bear biological meaning one by one. For such multivariate phenotypes, studying the pairwise associations between all measurements and all alleles is highly inefficient and prevents insight into the genetic pattern underlying the observed phenotypes. We present a new method for identifying patterns of allelic variation (genetic latent variables) that are maximally associated—in terms...

Data from: Cold adaptation shapes the robustness of metabolic networks in Drosophila melanogaster.

Caroline Margaret Williams, Miki Watanabe, Mario R. Guarracino, Maria Brigida Ferraro, Arthur S. Edison, Theodore J. Morgan, Arezue F. B. Boroujerdi, Dan A. Hahn & Daniel A. Hahn
When ectotherms are exposed to low temperatures, they enter a cold-induced coma (chill coma) that prevents resource acquisition, mating, oviposition, and escape from predation. There is substantial variation in time taken to recover from chill coma both within and among species, and this variation is correlated with habitat temperatures such that insects from cold environments recover more quickly. This suggests an adaptive response, but the mechanisms underlying variation in recovery times are unknown, making it...

VNS and seizure outcomes in pediatric refractory epilepsy: Systematic review and meta-analysis

Puneet Jain & Ravindra Arya
This data provides supplemental information for the systematic review and Meta-analysis. Supplemental tables report the detailed serach strategy (Supplementary Table 1), details of included studies (Supplementary Table 2), list of excluded studies (Supplementary Table 3), 50% Responder Rate in children with Lennox-Gastaut syndrome after VNS insertion (Supplementary Table 4), 50% Responder Rate in children with Dravet syndrome after VNS insertion (Supplementary Table 5), VNS settings and other seizure outcomes reported in the included studies (Supplementary...

Cellular dataset for: The anterior Hox gene ceh-13 and elt-1/GATA activate the posterior Hox genes nob-1 and php-3 to specify posterior lineages in the C. elegans embryo

Amanda Zacharias, John Isaac Murray, Elicia Preston, Jeremy Crawford, Jonathan Rumley, Prativa Amom, Breana Anderson, Priya Sivaramakrishnan, Shaili Patel, Barrington Bennett, Teddy Lavon & Felicia Peng
Hox transcription factors play a conserved role in specifying positional identity during animal development, with posterior Hox genes typically repressing the expression of more anterior Hox genes. Here, we dissect the regulation of the posterior Hox genes nob-1 and php-3 in the nematode C. elegans. We show that nob-1 and php-3 are co-expressed in gastrulation-stage embryos in cells that previously expressed the anterior Hox gene ceh-13. This expression is controlled by several partially redundant transcriptional...
