| 1 |  | Jorgensen, Erik | Nano-fEM: Protein localization using photo-activated localization microscopy and electron microscopy | Mapping the distribution of proteins is essential for understanding the function of proteins in a cell. Fluorescence microscopy is extensively used for protein localization, but subcellular context is often absent in fluorescence images. Immuno-electron microscopy, on the other hand, can localize pr... | | 2012-01-01 |
| 2 |  | Bohs, Lynn A. | Two new species from the brevantherum clade of solanum (solanaceae) from eastern Brazil | Two new species of Solanum (Solanaceae) from eastern Brazil are described. Solanum anisocladum Giacomin & Stehmann is similar to S. megalochiton Mart., but differs by the indument of the adaxial leaf surface, which is composed of long porrect-stellate and unbranched trichomes. It also has a more rob... | | 2013-01-01 |

| 4 |  | Crespo, Jose Guillermo | Dislodgement effect of natural semiochemicals released by disturbed triatomines: a possible alternative monitoring tool | The quick detection of domestic and peridomestic triatomines in their environments becomes difficult without the use of dislodgement substances that flush them out from their shelters. At present, tetramethrin 0.2% is being widely used in control programs. Although it is an efficient dislodging agen... | | 2013-01-01 |
| 5 |  | Ehleringer, James R. | Patterns of local and nonlocal water resource use across the western U.S. determined via stable isotope intercomparisons | In the western U.S., the mismatch between public water demands and natural water availability necessitates large interbasin transfers of water as well as groundwater mining of fossil aquifers. Here we identify probable situations of nonlocal water use in both space and time based on isotopic compari... | | 2014-01-01 |
| 6 |  | Blair, David F. | Metal centers of cytochrome c oxidase: structures and interactions | Studies directed toward the elucidation of the structures of the metal centers in cytochrome c oxidase are reviewed. Progress towards an understanding of the interactions between these centers and their spatial distributions within the protein will also be presented. Our studies are based primarily... | | 1983 |
| 7 |  | Potts, Wayne K. | MHC signaling during social communication | The major histocompatibility complex (MHC) has been known to play a critical role in immune recognition since the 1950s. It was a surprise, then, in the 1970s when the first report appeared indicating MHC might also function in social signaling. Since this seminal discovery, MHC signaling has been f... | | 2012-01-01 |
| 8 |  | Capecchi, Mario R. | Mice lacking endothelial ACE: normal blood pressure with elevated angiotensin II | Recently, the concept of local renin-angiotensin systems (RAS) capable of generating angiotensin II apart from the circulation has received considerable attention. To investigate this, we generated ACE 1/3 mice in which one allele of ACE is null and the second allele was engineered to express ACE o... | | 2003 |
| 9 |  | Capecchi, Mario R. | Mice lacking endothelial angiotensin-converting enzyme have a normal blood pressure | To test the hypothesis that local vascular production of angiotensin II is necessary for the normal regulation of blood pressure, we engineered a new line of genetically altered mice that lack endothelial angiotensin-converting enzyme (ACE). This was accomplished using a novel strategy of targeted... | | 2002 |
| 10 |  | Capecchi, Mario R. | Mice with cardiac-restricted angiotensin-converting enzyme (ACE) have atrial enlargement, cardiac arrhythmia, and sudden death | To investigate the local effects of angiotensin II on the heart, we created a mouse model with 100-fold normal cardiac angiotensin-converting enzyme (ACE), but no ACE expression in kidney or vascular endothelium. This was achieved by placing the endogenous ACE gene under the control of the α-myo... | Atrial enlargement; Cardiac arrhythmia; ACE | 2004 |
| 11 |  | Beckerle, Mary C. | Microinjected fluorescent polystyrene beads exhibit saltatory motion in tissue culture cells | Microinjected 0.26-um fluorescent, carboxylated microspheres were found to display classical saltatory motion in tissue culture cells .

| 13 |  | Adler, Frederick R. | Migration alone can produce persistence of host-parasitoid models | It has long been recognized that the unstable equilibrium of a single-patch predator-prey model cannot be stabilized by diffusive coupling with identical patches, since the coupled system acts exactly like the single-patch system if the patches are synchronized (Maynard Smith 1974; Allen 1975; Reeve... | Heterogeneity; Nicholson-Bailey; migration rates | 1993 |
| 14 |  | Jorgensen, Erik; Schuske, Kimberly R. | CAPS and syntaxin dock dense core vesicles to the plasma membrane in neurons | Docking to the plasma membrane prepares vesicles for rapid release. Here, we describe a mechanism for dense core vesicle docking in neurons. In Caenorhabditis elegons motor neurons, dense core vesicles dock at the plasma membrane but are excluded from active zones at synapses. | | 2008 |
| 15 |  | Hultine, Kevin | Carbon and nitrogen allocation to male and female reproduction in Rocky Mountain Douglas-fir (Pseudotsuga menziesii var. glauca, Pinaceae) | We measured carbon (respiration, photosynthesis, and production) and nitrogen allocation to male and female cones of Rocky Mountain Douglas-fir (Pseudotsuga menziesii var. glauca) to quantify gender-specific: (1) resource allocation to reproduction, and (2) contribution to carbon costs of reproducti... | Gender; photosynthesis; resource allocation | 2000 |
| 16 |  | Ehleringer, James R. | Carbon isotope discrimination and water relations of oak hybrid populations in southwestern Utah | The evergreen oak Quercus turbinella and the deciduous Q. gambelii form natural hybrids in southwestern Utah and northern Arizona.

| 23 |  | Olivera, Baldomero M. | Pyridine nucleotide metabolism in Escherichia coli. I. Exponential growth | The pyridine nucleotide pool of Escherichia coli is made up almost exclusively of DPN and TPN. In an exponentially growing glucose culture an average cell contains 1,460,000 molecules of DPN (30% reduced) and 440,000 molecules of TPN (57% reduced). If the total volume of the cell were accessible t... | Nicotinic acid | 1971 |
| 24 |  | Olivera, Baldomero M. | Pyridine nucleotide metabolism in Escherichia coli. II. Niacin starvation | The effect of niacin starvation has been studied in a niacin-requiring auxotroph of Escherichia coli. If a culture is totally deprived of niacin, cells continue to divide until the total pyridine nucleotide content has fallen from 1.9 X 10^6 to 1.2 X 10^5 molecules per cell. During starvation, the r... | Starvation; Nicotinic acid | 1973 |
| 25 |  | Olivera, Baldomero M. | Pyridine nucleotide metabolism in Escherichia coli. III. Biosynthesis from alternative precursors in vivo | In Escherichia coli, the nicotinamide moiety of pyridine nucleotides may be derived from de novo synthesis of the pyridine ring or through the uptake of either nicotinic acid or nicotinamide. De novo synthesis is the least preferred pathway; it is suppressed if an exogenous source is available. Nic... | Nicotinic acid; Biosynthesis | 1973 |
