DNA- and RNA-based stable isotope probing of hydrocarbon degraders.

, 2015
The microbial degradation of hydrocarbons in contaminated environments can be driven by distinct aerobic and anaerobic populations. While the physiology and biochemistry of selected degraders isolated in pure culture have been intensively studied in ...

Combining metagenomics with metaproteomics and stable isotope probing reveals metabolic pathways used by a naturally occurring marine methylotroph [PDF]

, 2015
A variety of culture-independent techniques have been developed that can be used in conjunction with culture-dependent physiological and metabolic studies of key microbial organisms in order to better understand how the activity of natural populations ...

Protic N‐Heterocyclic Carbene Ligands in Ruthenium‐Catalyzed Transfer Hydrogenation

Helvetica Chimica Acta, EarlyView.
The activity of ruthenium transfer hydrogenation catalysts is strongly influenced by the number of protic units in the N‐heterocyclic carbene ligand. Doubly protic NH, NH ligands induce slower activity than mono‐protic NH, NMe ligands, while NMe, NMe ligands display the highest activity, suggesting metal‐ligand cooperativity is not beneficial for these

Anaerobic carboxydotrophic bacteria in geothermal springs identified using stable isotope probing

Frontiers in Microbiology, 2015
Carbon monoxide (CO) is a potential energy and carbon source for thermophilic bacteria in geothermal environments. Geothermal sites ranging in temperature from 45–65°C were investigated for the presence and activity of anaerobic CO-oxidizing bacteria ...

Corticosterone and Mitochondrial Efficiency Are Associated With Changes in DNA Oxidative Damage During an Acute Stress Response in Leach's Storm‐Petrels (Hydrobates leucorhous)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The ability of organisms to effectively respond to challenges is critical for survival. We investigated how an acute stressor affected corticosterone, mitochondrial function, and DNA oxidative damage in a wild population of Leach's storm‐petrels (Hydrobates leucorhous).

A forensic approach to understanding habitat use from stable isotope analysis of (avian) claw material [PDF]

, 2003
1. The potential of using stable isotope signatures of avian claws in order to infer diet and habitat use was investigated. 2. Highly significant relationships observed between stable carbon and nitrogen isotope ratios (¹³C, &

Data‐Independent Acquisition Mass Spectrometry in Tumor Classification and Cancer Biomarker Research

Mass Spectrometry Reviews, EarlyView.
Abstract Cancer treatment is far from optimal also because current classification systems do not reflect the complex molecular status of the tumor and its phenotype in sufficient detail. To construct molecular tumor classifiers, omics tools provide complex molecular data reflecting many aspects from genotype to phenotype.

Acidotolerant Bacteria and Fungi as a Sink of Methanol-Derived Carbon in a Deciduous Forest Soil

Frontiers in Microbiology, 2017
Methanol is an abundant atmospheric volatile organic compound that is released from both living and decaying plant material. In forest and other aerated soils, methanol can be consumed by methanol-utilizing microorganisms that constitute a known ...

Proteomics of Nitrotyrosine: Integrating Mass Spectrometry and Immunodetection in Redox‐Driven Pathology

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Nitrooxidative stress, driven by excess reactive nitrogen species like peroxynitrite, contributes to the pathogenesis of many chronic diseases. Among its molecular footprints, 3‐nitrotyrosine (3NT) has emerged as a biologically relevant marker of protein nitration.
