The Twin Research Registry at SRI International
Twins in the TRR have participated in studies of complex, clinically relevant phenotypes that would not be feasible to measure in larger samples.

Nighttime Cardiac Sympathetic Hyper-Activation in Young Primary Insomniacs
Impedance cardiography and heart rate variability (HRV) measures were assessed in 9 insomniacs and 9 good sleepers during a night of polysomnographic recording.

Pharmacogenetic Smoking Cessation Intervention in a Health Care Setting: A Pilot Feasibility Study
We conducted a multiphased, mixed-methods feasibility study with current smokers to develop and evaluate a patient-centered, theoretically grounded personalized medicine treatment protocol.

A Multi-Omic Systems Approach to Elucidating Yersinia Virulence Mechanisms
In this study, a temporal multi-omic analysis of YP and YPT at physiologically relevant temperatures was performed to gain insights into how an acute and highly lethal bacterial pathogen, YP,…

Lessons from an Online Stop-Smoking Intervention: Adaptations for Mobile Implementation
A web-based tailored intervention yields valuable lessons for transitioning content from personal computers to the smaller form factor of a mobile device.

A Systematic Quantitative Proteomic Examination of Multidrug Resistance in Acinetobacter Baumannii
We have compared the proteome of the multidrug resistant strain BAA-1605, with the proteome of the drug-sensitive strain ATCC 17978, using iTRAQ labeling and online 2D LC/MS/MS for peptide/protein identification.

Variation in Longitudinal Trajectories of Regional Brain Volumes of Healthy Men and Women (Ages 10 to 85 Years) Measured with Atlas-Based Parcellation of MRI
We calculated trajectories of regional brain volume changes from T1-weighted (SPGR) MRI data, quantified with our automated, unsupervised SRI24 atlas-based registration and parcellation method.

Sub-Anesthetic Concentrations of (R,S)-Ketamine Metabolites Inhibit Acetylcholine-Evoked Currents in Alpha 7 Nicotinic Acetylcholine Receptors
The effect of the (R,S)-ketamine metabolites (R,S)-norketamine, (R,S)-dehydronorketamine, (2S,6S)-hydroxynorketamine and (2R,6R)-hydroxynorketamine on the activity of α7 and α3β4 neuronal nicotinic acetylcholine receptors was investigated using patch-clamp techniques.

Retrodialysis of N/Ofq into the Nucleus Accumbens Shell Blocks Cocaine-Induced Increases in Extracellular Dopamine and Locomotor Activity
This study sought to examine the effects of retrodialyzed N/OFQ on the cocaine-induced increase in extracellular dopamine levels in the NAc, as well as locomotor activity, in freely moving rats.

In Silico Systems Biology Approaches for the Identification of Antimicrobial Targets
We have compiled software tools and databases that are typically used for target identification through in silico analyses. We have also identified enzyme- and broad-spectrum metabolite-based drug targets that have…

Bed Bug Detection: Current Technologies and Future Directions
Industry surveys report a 100-fold increase in calls for bed bug control, and almost all pest control operations currently respond to bed bug problems.

Visual Search and the Aging Brain: Discerning the Effects of Age-Related Brain Volume Shrinkage on Alertness, Feature Binding, and Attentional Control
Poorer conjunction, but not feature, search performance was related to older age and volume shrinkage of nodes in the dorsolateral processing stream.
