Novel Pelagic Iron-Oxidizing Zetaproteobacteria from the Chesapeake Bay Oxic–Anoxic Transition Zone
(2017-07-18)
Chemolithotrophic iron-oxidizing bacteria (FeOB) could theoretically inhabit any environment where Fe(II) and O2 (or nitrate) coexist. Until recently, marine Fe-oxidizing Zetaproteobacteria had primarily been observed in ...
Real earnings management activities prior to bondissuance
(2017-06-01)
We examine real activities manipulation by firms prior to their debt issuances andhow such manipulation activities affect bond yield spreads. We find that bond-issuing firmsincrease their real activities manipulation in ...
Re-analyses of “Algal” Genes Suggest a Complex Evolutionary History of Oomycetes
(2017-09-06)
The spread of photosynthesis is one of the most important but constantly debated topics in eukaryotic evolution. Various hypotheses have been proposed to explain the plastid distribution in extant eukaryotes. Notably, the ...
PsrA controls the synthesis of the Pseudomonas aeruginosa quinolone signal via repression of the FadE homolog, PA0506
(2017-12-08)
Pseudomonas aeruginosa is a ubiquitous, Gram-negative opportunistic pathogen that can cause disease in various sites within the human body. This bacterium is a major source of nosocomial infections that are often difficult ...
Molecular targeting of the Aurora-A/SMAD5 oncogenic axis restores chemosensitivity in human breast cancer cells
(2017-09-01)
Although the majority of breast cancers initially respond to the cytotoxic effects of chemotherapeutic agents, most breast cancer patients experience tumor relapse and ultimately die because of drug resistance. Breast ...
Refugee Policy Implications of U.S. Immigration Medical Screenings: A New Era of Inadmissibility on Health-Related Grounds
(2017-09-24)
Refugees frequently face extended delays in their efforts to enter the United States (U.S.) and those who are successful, in many cases, encounter overwhelming obstacles, inadequate resources, and a complex system of legal ...
Quantitative analysis and comparison of 3D morphology between viable and apoptotic MCF-7 breast cancer cells and characterization of nuclear fragmentation
(2017-09-08)
Morphological changes in apoptotic cells provide essential markers for defining and detec- tion of apoptosis as a fundamental mechanism of cell death. Among these changes, the nuclear fragmentation and condensation have ...
Range expansion of a fouling species indirectly impacts local species interactions
(2017-10-19)
We investigated how recent changes in the distribution and abundance of a fouling organism affected the strength of interactions between a commercially important foundation species and a common predator. Increases in the ...
Molecular Connections between Cancer Cell Metabolism and the Tumor Microenvironment
(2015)
Cancer cells preferentially utilize glycolysis, instead of oxidative phosphorylation,
for metabolism even in the presence of oxygen. This phenomenon of aerobic glycolysis,
referred to as the “Warburg effect”, commonly ...
Integrated transcriptome, small RNA and degradome sequencing approaches provide insights into Ascochyta blight resistance in chickpea
(2018-10-16)
Ascochyta blight (AB) is one of the major biotic stresses known to limit the chickpea production worldwide. To dissect the complex mechanisms of AB resistance in chickpea, three approaches, namely, transcriptome, small RNA ...
