Prior research points to the importance of psychostimulants in improving self-control. However, the neural substrates underlying such improvement remain unclear. Here, in a pharmacological functional MRI study of the stop signal task, we show that methylphenidate (as compared with placebo) robustly decreased stop signal reaction time (SSRT), an index of(More)
By blocking dopamine and norepinephrine transporters, methylphenidate affects cognitive performance and regional brain activation in healthy individuals as well as those with neuropsychiatric disorders. Resting-state connectivity evaluates the functional integrity of a network of brain regions. Here, we examined how methylphenidate effects resting-state(More)
Many previous studies suggest the potential of psychostimulants in improving cognitive functioning. Our earlier pharmacological brain imaging study showed that intravenous methylphenidate (MPH) improves inhibitory control by altering cortico-striato-thalamic activations in cocaine-dependent (CD) individuals. Here we provide additional evidence for the(More)
Vancomycin is a glycopeptide antibiotic used in the treatment of gram-positive infections including methicillin-resistant Staphylococcus aureus (MRSA). The most common adverse reaction to vancomycin is red man syndrome, which is a histaminergic reaction causing a rash on the upper torso, neck, and face after rapid infusion of the drug. Less commonly,(More)
Pancreatic cancer is one of the most devastating solid tumor malignancies. Majority of patients have metastatic disease upon diagnosis. Five-year survival is less than 5% for all stages of pancreatic cancer combined. Gemcitabine has been the standard palliative therapy for advanced pancreatic cancer over the past decade. Many studies attempted to develop(More)
Background Denosumab therapy is commonly used for the prevention of skeletal-related events in patients with bone metastasis. However, a common side effect of denosumab is hypocalcemia. Objective The aim of the study is to determine the incidence of hypocalcemia in patients receiving denosumab for prevention of skeletal-related events in bone metastasis and(More)
Detection of a salient stimulus is critical to cognitive functioning. A stimulus is salient when it appears infrequently, carries high motivational value, and/or when it dictates changes in behavior. Individuals with neurological conditions that implicate altered catecholaminergic signaling, such as those with attention deficit hyperactivity disorder, are(More)
Alzheimer's disease is the most common cause of dementia in the United States. A better understanding of the disease's underlying pathways may provide novel treatment and/or prevention strategies for this progressive chronic neurodegenerative disorder. In recent years, there has been a growing interest in the possible links between insulin and Alzheimer's(More)
e19681 Background: Peripheral neuropathy (PN) is a cumulative toxicity of oxaliplatin (OX). Retrospective studies have reported that Ca/Mg infusions may reduce the incidence of PN and may allow patients to be treated without dose reductions for a longer duration. The objectives of this study were to retrospectively evaluate the effect of Ca/Mg on the number(More)
