Global environmental change has influenced lake surface temperatures, a key driver of ecosystem structure and function. Recent studies have suggested significant warming of water temperatures in individual lakes across many different regions around the world. However, the spatial and...

Coherence analysis discriminates between retroviral integration patterns in CD34(+) cells transduced under differing clinical trial conditions.

Mol Ther Methods Clin Dev. 2015 Apr 29;2:15015. doi: 10.1038/mtm.2015.15. eCollection 2015.

Unequivocal demonstration of the therapeutic utility of γ-retroviral vectors for gene therapy applications targeting the hematopoietic system was accompanied by instances of insertional mutagenesis. These events stimulated the ongoing development of putatively safer integrating vector systems and analysis methods...

Noninvasive Cathodoluminescence-Activated Nanoimaging of Dynamic Processes in Liquids.

ACS nano

Bischak CG, Wai RB, Cherqui C, Busche JA, Quillin SC, Hetherington CL, Wang Z, Aiello CD, Schlom DG, Aloni S, Ogletree DF, Masiello DJ, Ginsberg NS.
PMID: 28956598
ACS Nano. 2017 Oct 24;11(10):10583-10590. doi: 10.1021/acsnano.7b06081. Epub 2017 Sep 28.

In situ electron microscopy provides remarkably high spatial resolution, yet electron beam irradiation often damages soft materials and perturbs dynamic processes, requiring samples to be very robust. Here, we instead noninvasively image the dynamics of metal and polymer nanoparticles...

Lignin signatures show the effects of changes in heather and bracken cover on the composition of organic matter in a moorland soil profile.

Oecologia

Hetherington SL, Anderson JM.
PMID: 28308487
Oecologia. 1998 Nov;117(1):194-200. doi: 10.1007/s004420050648.

Bracken (Pteridium aquilinum) is aggressively displacing heather (Calluna vulgaris) on many moorlands in Britain. We investigated the use of lignin derivatives to identify the distribution of soil organic matter (SOM) derived from bracken in moorland soil profiles formed under...

Cathodoluminescence-activated nanoimaging: noninvasive near-field optical microscopy in an electron microscope.

Nano letters

Bischak CG, Hetherington CL, Wang Z, Precht JT, Kaz DM, Schlom DG, Ginsberg NS.
PMID: 25855869
Nano Lett. 2015 May 13;15(5):3383-90. doi: 10.1021/acs.nanolett.5b00716. Epub 2015 Apr 09.

We demonstrate a new nanoimaging platform in which optical excitations generated by a low-energy electron beam in an ultrathin scintillator are used as a noninvasive, near-field optical scanning probe of an underlying sample. We obtain optical images of Al...

Response to Energy Dilution in the Short Term: Evidence of Nutritional Wisdom in Young Children?.

Nutritional neuroscience

Hetherington MM, Wood C, Lyburn SC.
PMID: 27414130
Nutr Neurosci. 2000;3(5):321-9. doi: 10.1080/1028415X.2000.11747329.

Young children respond to energy dilution achieved using fat or sugar substitutes by compensating for reduced energy within a single meal. The ability to respond to energy dilution in the short term may diminish with age, since adults do...

Measuring stress signaling responses of stomata in isolated epidermis of graminaceous species.

Frontiers in plant science
