Co-occurrence of ecologically similar species of Hawaiian spiders reveals critical early phase of adaptive radiation
(2018-06-19)
Background:
The processes through which populations originate and diversify ecologically in the initial stages of adaptive radiation are little understood because we lack information on critical steps of early divergence. ...
Cryo-electron tomography of periplasmic flagella in Borrelia burgdorferi reveals a distinct cytoplasmic ATPase complex.
(2018-11-09)
Periplasmic flagella are essential for the distinct morphology and motility of spirochetes. A
flagella-specific type III secretion system (fT3SS) composed of a membrane-bound export
apparatus and a cytosolic ATPase complex ...
Comparison of non-invasive to invasive oxygenation ratios for diagnosing acute respiratory distress syndrome following coronary artery bypass graft surgery: a prospective derivation-validation cohort study
(2018-11-27)
Objective: To determine if non-invasive oxygenation indices, namely peripheral capillary oxygen saturation (SpO2)/
fraction of inspired oxygen (Fi
O2) and partial pressure of alveolar oxygen (PAO2)/Fi
O2 may be used as ...
Construction and characterization of a bacterial artificial chromosome library for Gossypium mustelinum
(2018-05-17)
A bacterial artificial chromosome (BAC) library for G. mustelinum Miers ex G. Watt (AD4)
was constructed. Intact nuclei from G. mustelinum (AD4) were used to isolate high molecular
weight DNA, which was partially cleaved ...
Dehiscence and embolization of CorMatrix tricuspid valve replacement in the setting of infective endocarditis: a case report
(2018-01-31)
Background:
Due to increased morbidity and mortality, prosthetic valve infective endocarditis (IE) with dehiscence requires urgent intervention. Early identification and therapy may prevent embolization.
Case summary:
A ...
Cooccurrence of prey species alters the impact of predators on prey performance through multiple mechanisms
(2018-08-11)
When prey are differentially affected by intra and interspecific competition, the cooccurrence of multiple prey species alters the per capita availability of food for a particular prey species which could alter how prey ...
Desiccation tolerance in Acinetobacter baumannii is mediated by the two-component response regulator BfmR
(2018-10-11)
For the opportunistic pathogen Acinetobacter baumannii, desiccation tolerance is thought to
contribute significantly to the persistence of these bacteria in the healthcare environment.
We investigated the ability of A. ...
Delineation and mapping of coastal shark habitat within a shallow lagoonal estuary
(2018-04-12)
Estuaries function as important nursery and foraging habitats for many coastal species, including highly migratory sharks. Pamlico Sound, North Carolina, is one of the largest estuaries in the continental United States and ...
Effects of Social Experience on the Habituation Rate of Zebrafish Startle Escape Response: Empirical and Computational Analyses
(2018-02-05)
While the effects of social experience on nervous system function have been extensively investigated in both vertebrate and invertebrate systems, our understanding of how social status differentially affects learning remains ...
Electronic Health Literacy Across the Lifespan: Measurement Invariance Study
(2018-09-07)
Background: Electronic health (eHealth) information is ingrained in the healthcare experience to engage patients across the lifespan. Both eHealth accessibility and optimization are influenced by lifespan development, as ...
