An 85-year-old woman with history of melanoma is referred for a follow-up 18F-FDG PET/CT. 18F-FDG PET/CT scan showed bilateral and peripheral ground-glass opacities in upper and lower pulmonary lobes surrounded by consolidations of crescent shape with increased FDG uptake, findings compatible with organizing pneumonia. Following further inquiry, the patient reported low-grade fever, sore throat, and fatigue for the past 6 days. Because of the ongoing COVID-19 pandemic, the patient was tested for...
The incidence of COVID-19, a severe acute respiratory syndrome caused by SARS-CoV-2, is rapidly growing worldwide. In this pandemic period, the chance of incidental pulmonary findings suggestive of COVID-19 at 18F-FDG PET/CT in asymptomatic oncological patients is not negligible. To suspect COVID-19 is more demanding whether its presentation is atypical. We describe the incidental PET/CT detection of an 18F-FDG–avid isolated centrilobular pulmonary consolidation in an asymptomatic lymphoma patient,...
We present the case of a patient who underwent 18F-fluorocholine PET/CT for biochemical recurrence of prostate cancer in which bilateral pneumonia was diagnosed. In the current state of COVID-19 pandemic, a high prevalence of incidental pneumonia may be expected, even with previous clinical triage, explained by a nondefined number of patients who were asymptomatic or minimally symptomatic for infectious process. Therefore, nuclear medicine physicians should be prepared to recognize and diagnose incidental...

Abstract Coronary arteries have high curvatures, and hence, flow through them causes disturbed flow patterns, resulting in stenosis and atherosclerosis. This in turn decreases the myocardial flow perfusion, causing myocardial ischemia and infarction. Therefore, in order to understand the mechanisms of these phenomena caused by high curvatures and branching of coronary arteries, we have conducted elaborate hemodynamic analysis for both (i) idealized coronary arteries with geometrical...

Abstract The ability to promptly respond to behaviourally relevant events depends on both general alertness and phasic changes in attentional state driven by temporal expectations. Using a variable foreperiod simple reaction time (RT) task in four adult male rhesus macaques, we investigated the role of the cholinergic system in alertness and temporal expectation. Foreperiod‐effects on RT reflect temporal expectation, while alertness is quantified as overall response speed. We measured these RT parameters...
Abstract Marijuana intoxication impairs neurocognitive functions. Common side effects of consuming cannabis include time distortion and memory loss. However, the underlying neurophysiological mechanisms involved in these effects remain unclear. We hypothesized that communication between the hippocampal CA1 region and medial entorhinal cortex (MEC) is essential for the transmission of temporal‐associated information. We used a differential‐reinforcement‐of‐low‐rate (DRL) task, which requires subjects...
Abstract Perineuronal nets (PNNs) represent a highly condensed specialized form of brain extracellular matrix (ECM) enwrapping mostly parvalbumin‐positive interneurons in the brain in a mesh‐like fashion. PNNs not only regulate the onset and completion of the critical period during postnatal brain development, control cell excitability and synaptic transmission but are also implicated in several brain disorders including schizophrenia. Holes in the perineuronal nets, harboring the synaptic contacts,...
Abstract The striatum is the main input stage of the basal ganglia receiving extrinsic input from cortex and thalamus. The striatal projection neurons (SPN) constitute 95% of the neurons in the striatum in mice while the remaining 5% are cholinergic and GABAergic interneurons. The cholinergic (ChIN) and low threshold spiking interneurons (LTS) are spontaneously active, and form a striatal subnetwork involved in salience detection and goal‐directed learning. Activation of ChINs have been shown to...
Abstract Repetitive passive movement (RPM) is a rehabilitation technique that increases spinal reciprocal inhibition (RI) as movement speed increases. However, characterization of the RPM movement number, frequency, and range relative to the afferent impulses of muscle spindles and RI modulation has not been performed. In this study, we attempted to clarify these factors and evaluate their relationship to RI. We used 20 healthy adults for our first experiment (Experiment 1) and 16 healthy adults...

Enteric neural crest cells (ENCCs) were isolated from 14 days rat embryos, cultured into neurospheres, and labeled via GFP transduction. Inhibition of the ROCK pathway increased the viable cell number and growth, differentiation, and migration of ENCCs in vitro. Moreover, transplantation of GFP‐labeled ENCCs into the chemically induced hypoganglionic gut showed enhanced survival and expanded distribution of transplanted ENCCs upon treatment with ROCK inhibitor Y‐27632 in vivo. Abstract Background...
The diagnosis of functional constipation (FC) is based on the Rome criteria. The last edition of the criteria (Rome IV) for infants and toddlers modified the criteria to differentiate toilet‐trained (TT) and non‐toilet‐trained (NTT) children. We aimed to understand the impact of adding toilet training to the diagnostic criteria and to assess the prevalence of FC. We found that TT children are more likely to have FC, and there were no changes in the prevalence of FC using the Rome IV criteria vs Rome...
Abstract Background The vagus nerve has anti‐inflammatory properties. We aimed to investigate vagus nerve stimulation (VNS) as a new therapeutic strategy targeting an intrinsic anti‐inflammatory pathway in a pilot study in Crohn's disease patients. The main objectives addressed the questions of long‐term safety, tolerability, and anti‐inflammatory effects of this therapy. This study is the continuation of previous reported findings at 6 months. Methods Nine patients with moderate active...

The peripheral nervous system lacks lymphatic vessels and is protected by the blood–nerve barrier. In the present study, increased expression of lymphatic vessel endothelial hyaluronan receptor 1 (LYVE‐1) and Prospero Homeobox 1 (Prox1) were observed in the sciatic nerve 7 days after injury, suggesting the presence of lymphatic vessels. Therefore, this study provides evidence of new lymphatic vessels involvement (mediated by Prox1) in nerve repair after sciatic nerve injury. Abstract The peripheral...
