Yasunori Suematsu, Masaki Goto, Christina Park, Ane C.F. Nunes, WangHui Jing, Elani Streja, Connie M. Rhee, Siobanth Cruz, Moti L. Kashyap, Nosratola D. Vaziri, Vasanthy Narayanaswami, Kamyar Kalantar-Zadeh & Hamid Moradi
Context: In end-stage renal disease (ESRD), serum high-density lipoprotein cholesterol (HDL-C) level is not an accurate predictor of mortality, partly because it does not necessarily correlate with indices of HDL function. Paraoxonase (PON) is a major enzyme constituent of HDL and key component of HDL antioxidant activity. Apolipoprotein (Apo) A-I is the core HDL structural protein that plays a major role in various aspects of HDL function. Objective: We sought to examine PON activity and...

Data from: Multichannel Stroboscopic Videography (MSV): A technique for visualizing multiple channels for behavioral measurements.

Alberto Soto, Matthew McHenry & Theodora Po
Biologists commonly visualize dierent features of an organism using distinct sources of illumination. Multichannel imaging has largely not been applied to behavioral studies due to the challenges posed by a moving subject. We address this challenge with the technique of Multichannel Stroboscopic Videography (MSV), which synchronizes multiple strobe lights with video exposures of a single camera. We illustrate the utility of this approach with kinematic measurements of a walking cockroach (Gromphadorhina portentosa) and calculations of...

Data from: Elevational cline in herbivore abundance driven by a monotonic increase in trophic level sensitivity to aridity

Annika S. Nelson, Cole T. Symanski, Matthew J. Hecking & Kailen A. Mooney
1. The abiotic environment drives species abundances and distributions both directly and indirectly through effects on multi-trophic species interactions. However, few studies have documented the individual and combined consequences of these direct and indirect effects. 2. We studied an ant-tended aphid along an elevational gradient, where lower elevations were more arid. Hypotheses of stronger species interactions at lower elevations and a greater sensitivity of higher trophic levels to climate led us to predict increased top-down...

Positive allosteric modulation of the α7 nicotinic acetylcholine receptor as a treatment for cognitive deficits after traumatic brain injury

David Titus, Timothy Johnstone, Nathan Johnson, Sidney London, Meghana Chapalamadugu, Derk Hogenkamp, Kelvin Gee & Coleen Atkins
Cognitive impairments are a common consequence of traumatic brain injury (TBI). The hippocampus is a subcortical structure that plays a key role in the formation of declarative memories and is highly vulnerable to TBI. The α7 nicotinic acetylcholine receptor (nAChR) is highly expressed in the hippocampus and reduced expression and function of this receptor are linked with cognitive impairments in Alzheimer’s disease and schizophrenia. Positive allosteric modulation of α7 nAChRs with AVL-3288 enhances receptor currents...

Figures for \"California forest die-off linked to multi-year deep soil drying in 2012-2015 drought\"

Michael Goulden
Data underlying main figures in "California forest die-off linked to multi-year deep soil drying in 2012-2015 drought", published in Nature-Geoscience, July 2019, ML Goulden and RC Bales. Abstract of paper: Widespread episodes of recent forest die-off have been tied to the occurrence of anomalously warm droughts, though the underlying mechanisms remain inadequately understood. California’s 2012-2015 drought, with exceptionally low precipitation and warmth and widespread conifer death, provides an opportunity to explore the chain of events...

Environmental drivers of adult locomotion and reproduction in a symbiont-hosting sea anemone

Samuel Bedgood
This data was collected from the sea anemone species Exaiptasia diaphana collected in the Florida Keys in January 2016. Anemones were brought into the lab where they were exposed to feeding treatments (fed or starved) and algal symbiont manipulations (high or low symbiont denisties). We collected data on movement via time lapse photography, reproduction via counting of pedal lacerates, and anemone size via photography and analysis in the program ImageJ. We found that feeding treatments...

Rhythm of Attention

Haleh Farahbod, Kourosh Saberi & Gregory Hickok
Modulation patterns are known to carry critical predictive cues to signal detection in complex acoustic environments. The current study investigated the persistence of masker modulation effects on post-modulation detection of probe signals. Hickok et al. (2015) demonstrated that thresholds for a tone pulse in stationary noise follow a predictable periodic pattern when preceded by a 3-Hz amplitude modulated masker. They found entrainment of detection patterns to the modulation envelope lasting for approximately 2 cycles after...

Grounding line, elevation changes, and melt rates maps of Denman Glacier, East Antarctica. Using satellite radar interferometry from the COSMO-SkyMed mission we map the grounding line of Denman Glacier, East Antarctica. We complement these data with some historical interferometric radar acquisition from the European satellite ERS-1/2. We present new maps of elevation changes on the grounded and floating portions of Denman Glacier obtained by temporally differencing TanDEM-X Digital Elevation Models.

Aerosol particle measurements taken during the airborn ARISTO 2016 campaign.

John Ortega, James Smith, Jefferson Snider & J. Michael Reeves
Several different types of measurements of particle size and concentration were compared during the 2016 Airborne Research Instrumentation Testing Opportunity (ARISTO) campaign. The scanning mobility particle sizer (SMPS) measured number-size distributions for mobility diameters between ~20-350 nm or ~8-110 nm, depending on the mobility analyzer chosen. Also included were two stand-alone condensation particle counters (CPC) for determining size-integrated particle concentrations. A wing-mounted and a rack-mounted Ultra-High Sensitivity Aerosol Spectrometer (UHSAS) were used to measure size...

Data from: Diet variability among insular populations of Podarcis lizards reveals diverse strategies to face resource-limited environments

Maxime Taverne, Anne-Claire Fabre, Nina King-Gillies, Marija Krajnović, Duje Lisičić, Louise Martin, Leslie Michal, Donat Petricioli, Anamaria Stambuk, Zoran Tadić, Chloé Vigliotti, Beck Wehrle & Anthony Herrel
Access to resources is a dynamic and multi-causal process that determines the success and survival of a population. It is therefore often challenging to disentangle the factors affecting ecological traits like diet. Insular habitats provide a good opportunity to study how variation in diet originates, in particular in populations of mesopredators such as lizards. Indeed, high levels of population density associated with low food abundance and low predation are selection pressures typically observed on islands....

Data from: Insensitivity of the cloud response to surface warming under radical changes to boundary layer turbulence and cloud microphysics: results from the ultraparameterized CAM

Hossein Parishani
This data set contains the simulation outputs used in the study summarized below: We study the cloud response to a +4K surface warming in a new multiscale climate model that uses enough interior resolution to begin explicitly resolving boundary layer turbulence (i.e., ultraparameterization or UP). UP's predictions are compared against those from standard superparameterization (SP). The mean cloud radiative effect feedback turns out to be remarkably neutral across all of our simulations, despite some radical...

Melinda Nicewonger, Murat Aydin & Eric Saltzman
Measurements of the abundance of acetylene and ethane in surface air flasks from Cape Grim, Australia (CGO) and South Pole, Antarctica (SPO) were made in the Saltzman/Aydin Research Group at the University of California, Irvine. The surface flasks are from the the NOAA Halocarbons and other Atmospheric Trace Species (HATS) monitoring network shared with UC Irvine by Dr. Stephen Montzka to compliment on-going ice core research at UC Irvine involving the same trace species.

Toward low-cloud-permitting cloud superparameterization with explicit boundary layer turbulence -- simulation data

Hossein Parishani, Michael Pritchard, Christopher Bretherton, Matthew Wyant & Marat Khairoutdinov
This data set contains the simulation outputs used in the study summarized below: Systematic biases in the representation of boundary layer (BL) clouds are a leading source of uncertainty in climate projections. A variation on superparameterization (SP) called ‘‘ultraparameterization’’ (UP) is developed, in which the grid spacing of the cloud-resolving models (CRMs) is fine enough (250x20 m) to explicitly capture the BL turbulence, associated clouds, and entrainment in a global climate model capable of multiyear...

Eric Saltzman
This data set contains air/sea eddy covariance fluxes and related data measured at the US Army Corps of Engineers Field Research Facility (USACE FRF) at Duck, North Carolina. The goal of this study was to determine transfer velocities for momentum, water vapor, and sulfur dioxide in order to study the processes controlling air/sea deposition of highly soluble gases. The measurements were made during March and April, 2015.

Data from: Physician champions’ perspectives and practices on electronic health records implementation: challenges and strategies

Xinning Gui, Yunan Chen, Xiaomu Zhou, Tera L. Reynolds, Kai Zheng & David A. Hanauer
Objective: Physician champions are “boots on the ground” physician leaders who facilitate the implementation of, and transition to, new health information technology (HIT) systems within an organization. They are commonly cited as key personnel in HIT implementations, yet little research has focused on their practices and perspectives. Methods: We addressed this research gap through a qualitative study of physician champions that aimed to capture their challenges and strategies during a large-scale HIT implementation. Email interviews...
