Analysis of Heme Using a Combination of Total Reflection X‐Ray Fluorescence Analysis and Solid‐Phase Extraction

X-Ray Spectrometry, EarlyView.
ABSTRACT In this study, a method to analyze iron originating from heme using a combination of total reflection X‐ray fluorescence (TXRF) analysis and solid‐phase extraction is presented. In this method, heme in a sample solution was collected on a reverse‐phase solid‐phase extraction column filled with octadecyl bonded silica, and then the collected ...

Influence of Asymmetry on the Molecular and Electronic Structures of μ‐Oxo Diferric Complexes

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The 6‐methyl substituents at the pyridines (shown in red) enforce longer MNpy bonds than without them (shown in green).The asymmetric dinucleating susanH2Me2 is used for the synthesis of a μ‐oxo diferric complex. Comparison to the two symmetric complexes of susan and susan6−Me shows a strong effect on the redox potentials.

An Overlooked Habitat‐Dependent Link Between Metabolism and Water Loss in Reptiles

Integrative Zoology, EarlyView.
We measured the gas exchange of six lizard and six snake species, under high and low air humidity, and two intriguing patterns emerged. First, although desert species lose less water via evaporation than similar‐sized mesic species under similar conditions, water loss is virtually the same when each is exposed to its natural conditions.

Low‐dose X‐ray radiation induces an adaptive response: A potential countermeasure to galactic cosmic radiation exposure

Experimental Physiology, EarlyView.
Abstract Space exploration involves many dangers including galactic cosmic radiation (GCR). This class of radiation includes high‐energy protons and heavy ionizing ions. NASA has defined GCR as a carcinogenic risk for long‐duration space missions. To date, no clear strategy has been developed to counter chronic GCR exposure.
