Population signals from neuronal ensembles in cortex during behavior are commonly measured with EEG, local field potential (LFP), and voltage-sensitive dyes. A genetically encoded voltage indicator would be useful for detection of such signals in specific cell types. Here we describe how this goal can be achieved with Butterfly, a voltage-sensitive(More)
The spinal synaptic plasticity is associated with a central sensitization of nociceptive input, which accounts for the generation of hyperalgesia in chronic pain. However, how group I metabotropic glutamate receptors (mGluRs) may operate spinal plasticity remains essentially unexplored. Here, we have identified spike-timing dependent synaptic plasticity in(More)
Although hypoxia is known to affect membrane excitability of various neurons by various mechanisms, the effects of hypoxia on substantia gelatinosa (SG) neurons have not yet been elucidated. In whole-cell or perforated patch-clamp recordings from SG neurons, we showed that acute hypoxia induces a reversible hyperpolarization of -6.1+/-1.3 mV of the resting(More)
Dendrites are neuronal structures specialized for receiving and processing information through their many synaptic inputs. How input strengths are modified across dendrites in ways that are crucial for synaptic integration and plasticity remains unclear. We examined in single hippocampal neurons the mechanism of heterosynaptic interactions and the(More)
BACKGROUND AND PURPOSE Advantages of new oral anticoagulations may be greater in atrial fibrillation (AF) patients of poor anticoagulation control with warfarin. The SAMe-TT2R2 scoring system, based on clinical variables, was recently developed to aid in identifying these patients. In this study, we investigated the association of this clinical composite(More)
Spontaneous pneumothorax occurs in up to 35% of patients with Pneumocystis jirovecii pneumonia. However, spontaneous pneumomediastinum and pneumopericardium are uncommon complications in patients infected with human immunodeficiency virus, with no reported incidence rates, even among patients with acquired immunodeficiency syndrome (AIDS) and P. jirovecii(More)
A 51-year-old man was being admitted to the emergency department with chest pains. He had a history of acute myocardial infarction (MI) on two prior occasions and was successfully treated with drug eluting stents. He was diagnosed with 3 consecutive events of acute MI in 3 different vessels. The consecutive events of acute MI in different vessels are a very(More)
To the Editor, Cytomegalovirus (CMV) infections occur in up to 60% of kidney transplant recipients, with most cases developing between the second and 6 months after transplantation [1]. The clinical manifestations of CMV infection vary widely. Asymptomatic viremia is the most common symptom, although the infection can occasionally invade various organs such(More)
We have investigated the effect of hypoxia on the excitatory synaptic transmission in the substantia gelatinosa neurons using perforated-patch-clamp configuration. Brief periods of hypoxia induced a depression in the evoked excitatory postsynaptic current (eEPSC) amplitude. The hypoxia-induced depression of eEPSC was not observed in the presence of(More)
