Adult age differences in frontostriatal representation of prediction error but not reward outcome.
(Cogn Affect Behav Neurosci, 2014-06)Emerging evidence from decision neuroscience suggests that although younger and older adults show similar frontostriatal representations of reward magnitude, older adults often show deficits in feedback-driven reinforcement ... -
Algal blooms and the nitrogen-enrichment hypothesis in Florida springs: evidence, alternatives, and adaptive management.
(Ecol Appl, 2010-04)Contradictions between system-specific evidence and broader paradigms to explain ecosystem behavior present a challenge for natural resource management. In Florida (U.S.A.) springs, increasing nitrate (NO3-) concentrations ... -
Bioluminescence imaging of glucose in tissue surrounding polyurethane and glucose sensor implants.
(J Diabetes Sci Technol, 2010-09-01)BACKGROUND: The bioluminescence technique was used to quantify the local glucose concentration in the tissue surrounding subcutaneously implanted polyurethane material and surrounding glucose sensors. In addition, some implants ... -
BOLD signal compartmentalization based on the apparent diffusion coefficient.
(Magn Reson Imaging, 2002-09)Functional MRI (fMRI) can detect blood oxygenation level dependent (BOLD) hemodynamic responses secondary to neuronal activity. The most commonly used method for detecting fMRI signals is the gradient-echo echo-planar imaging ... -
Cell cycle Start is coupled to entry into the yeast metabolic cycle across diverse strains and growth rates.
(Mol Biol Cell, 2016-01-01)Cells have evolved oscillators with different frequencies to coordinate periodic processes. Here we studied the interaction of two oscillators, the cell division cycle (CDC) and the yeast metabolic cycle (YMC), in budding ... -
Cerebral oxygenation and optimal vascular brain organization.
(J R Soc Interface, 2015-06-06)The cerebral vascular network has evolved in such a way so as to minimize transport time and energy expenditure. This is accomplished by a subtle combination of the optimal arrangement of arteries, arterioles and capillaries ... -
Co-activation of the amygdala, hippocampus and inferior frontal gyrus during autobiographical memory retrieval.
(Neuropsychologia, 2005)Functional MRI was used to investigate the role of medial temporal lobe and inferior frontal lobe regions in autobiographical recall. Prior to scanning, participants generated cue words for 50 autobiographical memories and ... -
Differentiating sensitivity of post-stimulus undershoot under diffusion weighting: implication of vascular and neuronal hierarchy.
(PLoS One, 2008-08-13)The widely used blood oxygenation level dependent (BOLD) signal during brain activation, as measured in typical fMRI methods, is composed of several distinct phases, the last of which, and perhaps the least understood, is ... -
Functional neuroimaging of emotionally intense autobiographical memories in post-traumatic stress disorder.
(J Psychiatr Res, 2011-05)Post-traumatic stress disorder (PTSD) affects regions that support autobiographical memory (AM) retrieval, such as the hippocampus, amygdala and ventral medial prefrontal cortex (PFC). However, it is not well understood ... -
Inkless microcontact printing on SAMs of Boc- and TBS-protected thiols.
(Nano Lett, 2010-01)We report a new inkless catalytic muCP technique that achieves accurate, fast, and complete pattern reproduction on SAMs of Boc- and TBS-protected thiols immobilized on gold using a polyurethane-acrylate stamp functionalized ... -
Mapping the semantic structure of cognitive neuroscience.
(J Cogn Neurosci, 2014-09)Cognitive neuroscience, as a discipline, links the biological systems studied by neuroscience to the processing constructs studied by psychology. By mapping these relations throughout the literature of cognitive neuroscience, ... -
Modified INOvent for delivery of inhaled nitric oxide during cardiac MRI.
(Magn Reson Imaging, 2011-10)BACKGROUND: The aim of this study was to assess the feasibility of delivering NO through a modified system to allow clearance of the magnetic field and thus compatibility with cardiac magnetic resonance (CMR). Nitric oxide ... -
Neural correlates of emotional processing in depression: changes with cognitive behavioral therapy and predictors of treatment response.
(J Psychiatr Res, 2011-05)Major depressive disorder (MDD) is characterized by the presence of disturbances in emotional processing. However, the neural correlates of these alterations, and how they may be affected by therapeutic interventions, remain ... -
Neural mechanisms of context effects on face recognition: automatic binding and context shift decrements.
(J Cogn Neurosci, 2010-11)Although people do not normally try to remember associations between faces and physical contexts, these associations are established automatically, as indicated by the difficulty of recognizing familiar faces in different ... -
Noninvasive monitoring of tissue hemoglobin using UV-VIS diffuse reflectance spectroscopy: a pilot study.
(Opt Express, 2009-12-21)We conducted a pilot study on 10 patients undergoing general surgery to test the feasibility of diffuse reflectance spectroscopy in the visible wavelength range as a noninvasive monitoring tool for blood loss during surgery. ... -
Oxygen for relief of dyspnoea in mildly- or non-hypoxaemic patients with cancer: a systematic review and meta-analysis.
(Br J Cancer, 2008-01-29)The aim of this study was to determine the efficacy of palliative oxygen for relief of dyspnoea in cancer patients. MEDLINE and EMBASE were searched for randomised controlled trials, comparing oxygen and medical air in cancer ... -
Poor adoption of hemodynamic optimization during major surgery: are we practicing substandard care?
(Anesth Analg, 2011-06) -
Provoked exercise desaturation in patent foramen ovale and impact of percutaneous closure.
(JACC Cardiovasc Interv, 2012-04)OBJECTIVES: This study was designed to assess the prevalence of provoked exercise desaturation (PED) in patients with patent foramen ovale (PFO) referred for cardiovascular evaluation and to evaluate the impact of PFO closure. ... -
Rationale and design of the Exercise Intensity Trial (EXCITE): A randomized trial comparing the effects of moderate versus moderate to high-intensity aerobic training in women with operable breast cancer.
(BMC Cancer, 2010-10-06)BACKGROUND: The Exercise Intensity Trial (EXcITe) is a randomized trial to compare the efficacy of supervised moderate-intensity aerobic training to moderate to high-intensity aerobic training, relative to attention control, ... -
