Endoplasmic reticulum targeted GFP reveals ER organization in tobacco NT-1 cells during cell division
The endoplasmic reticulum (ER) of plant cells undergoes a drastic reorganization during cell division. In tobacco NT-1 cells that stably express a GFP construct targeted to the ER, we have mapped the reorganization of ...
In vivo functional properties of juxtaglomerular neurons in the mouse olfactory bulb
(Frontiers Media S.A., 2013-02-21)
Juxtaglomerular neurons represent one of the largest cellular populations in the mammalian olfactory bulb yet their role for signal processing remains unclear. We used two-photon imaging and electrophysiological recordings ...
Minimum entropy decomposition : unsupervised oligotyping for sensitive partitioning of high-throughput marker gene sequences
(Nature Publishing Group, 2014-10-17)
Molecular microbial ecology investigations often employ large marker gene datasets, for example, ribosomal RNAs, to represent the occurrence of single-cell genomes in microbial communities. Massively parallel DNA sequencing ...
Hyperpolarization-activated currents and subthreshold resonance in granule cells of the olfactory bulb
(Society for Neuroscience, 2016-10-27)
An important contribution to neural circuit oscillatory dynamics is the ongoing activation and inactivation of hyperpolarization-activated currents (Ih). Network synchrony dynamics play an important role in the initial ...
Intentional versus unintentional nitrogen use in the United States : trends, efficiency and implications
Human actions have both intentionally and unintentionally altered the global economy of nitrogen (N), with both positive and negative consequences for human health and welfare, the environment and climate change. Here we ...
Microstructural and biochemical characterization of the nanoporous sucker rings from Dosidicus gigas
Recent interest in the development of environmentally benign routes to the synthesis of novel multifunctional materials has resulted in numerous investigations into structure-function relationships of a wide range of ...
Entropy-driven formation of a chiral liquid-crystalline phase of helical filaments
(American Physical Society, 2006-01-11)
We study the liquid-crystalline phase behavior of a concentrated suspension of helical flagella isolated from Salmonella typhimurium. Flagella are prepared with different polymorphic states, some of which have a pronounced ...
Denitrification across landscapes and waterscapes : a synthesis
(Ecological Society of America, 2006-12)
Denitrification is a critical process regulating the removal of bioavailable nitrogen (N) from natural and human-altered systems. While it has been extensively studied in terrestrial, freshwater, and marine systems, there ...
Distribution of postsynaptic density (PSD)-95 and Ca2+/calmodulin-dependent protein kinase II at the PSD
(Society for Neuroscience, 2003-12-03)
Postsynaptic densities (PSDs) contain proteins that regulate synaptic transmission. We determined the positions of calcium/calmodulin-dependent protein kinase II (CaMKII) and PSD-95 within the three-dimensional structure ...
Correction to “Importance of carbon-nitrogen interactions and ozone on ecosystem hydrology during the 21st century”
(American Geophysical Union, 2009-08-22)
