Precise control of dendritic spine density and synapse formation is critical for normal and pathological brain functions. Therefore, signaling pathways influencing dendrite outgrowth and remodeling remain a subject of extensive investigations. Here we report that prolonged activation of the serotonin 5-HT7 receptor (5-HT7R) with selective agonist LP-211 promotes formation of dendritic spines and facilitates synaptogenesis in postnatal cortical and striatal neurons. Critical role of 5-HT7R in neuronal morphogenesis was confirmed by analysis of neurons isolated from 5-HT7R-deficient mice and by pharmacological inactivation of the receptor...

Music is a universal language, present in all human societies. It pervades the lives of most human beings and can recall memories and feelings of the past, can exert positive effects on our mood, can be strongly evocative and ignite intense emotions, and can establish or strengthen social bonds. In this review, we summarize the research and recent progress on the origins and neural substrates of human musicality as well as the changes in brain plasticity elicited by listening or performing music. Indeed, music improves performance in a number of cognitive tasks and may have beneficial effects on diseased brains...

Parkinson's disease is a debilitating neurodegenerative disorder that is pathologically characterized by intracellular inclusions comprised primarily of alpha-synuclein (αSyn) that can also be transmitted from neuron to neuron. Several lines of evidence suggest that these inclusions cause neurodegeneration. Thus exploring strategies to improve neuronal survival in neurons with αSyn aggregates is critical. Previously, exposure to αSyn pre-formed fibrils (PFFs) has been shown to induce aggregation of endogenous αSyn resulting in cell death that is exacerbated by either starvation or inhibition of mTOR by rapamycin, both of which are able to induce autophagy, an intracellular protein degradation pathway...

The science of lung ultrasound has grown tremendously over the last two decades and lung ultrasound has not only entered the mainstream of point of care ultrasound but has become a dominant topic. Understanding lung ultrasound signs and artifacts is critical to being able to correlate findings with actual pathology and normal anatomy and physiology. Investigators have described multiple lung ultrasound artifacts and findings and it is important to understand both the physics and anatomic basis behind them...

Lewy bodies and Lewy neurites composed primarily of α-synuclein characterize synucleinopathies including Parkinson's disease (PD) and Dementia with Lewy Bodies (DLB). Despite decades of research on the impact of α-synuclein, little is known how abnormal inclusion made of this protein compromise neuronal function. Emerging evidence suggests that defects in axonal transport caused by aggregated α-synuclein contribute to neuronal dysfunction. These defects appear to occur well before the onset of neuronal death...

OBJECTIVE: Lung and venous ultrasound are bedside diagnostic tools increasingly used in the early diagnostic approach of suspected pulmonary embolism (PE). However, the possibility of improving the conventional prediction rule for PE by integrating ultrasound has never been investigated. METHODS: We performed lung and venous ultrasound in consecutive patients suspected of PE in four emergency departments. Conventional Wells score (Ws) was adjudicated by the attending physician, and ultrasound was performed by one of 20 investigators...

OBJECTIVE: To report our experience concerning sustained response (SR) after TPO-RA discontinuation in adult pITP patients and to identify possible predictive factors for outcome. METHODS: Thirty-nine pITP patients who received a TPO-RA were evaluated. Response (R) was defined as a platelet count ≥30 × 10(9) /L and at least a twofold increase in the baseline count and complete response (CR) as a platelet count ≥100 × 10(9) /L, in the absence of bleeding. Durable response (DR) was defined as a R/CR persisting ≥4 wk with a stable dose of TPO-RA, and SR as the first assessed platelet count ≥30 × 10(9) /L, available at more than 4 wk after discontinuation of TPO-RA, in the absence of other concomitant or rescue therapies...

Objectives Diarrheal disease is a significant cause of morbidity among children in Peru. Oral rehydration therapy (ORT) is a cost-effective evidence-based approach to treat diarrhea in young children, yet many Peruvian children in poorer households do not receive this life-saving treatment. This study investigates the social determinants of care-seeking behavior and utilization of appropriate home treatment for diarrheal episodes. Methods We used the nationally-representative 2008 Peru Demographic and Health Survey to: (1) describe the burden of non-bloody diarrheal disease among children <5 years old; and (2) identify socioeconomic correlates of care-seeking behavior and utilization/appropriateness of treatment among mothers of children with recent non-bloody diarrheal episodes (N = 1365)...

UNLABELLED: Pathologic inclusions define α-synucleinopathies that include Parkinson's disease (PD). The most common genetic cause of PD is the G2019S LRRK2 mutation that upregulates LRRK2 kinase activity. However, the interaction between α-synuclein, LRRK2, and the formation of α-synuclein inclusions remains unclear. Here, we show that G2019S-LRRK2 expression, in both cultured neurons and dopaminergic neurons in the rat substantia nigra pars compact, increases the recruitment of endogenous α-synuclein into inclusions in response to α-synuclein fibril exposure...

CONTEXT: Lung transplantation is limited by donor lung availability with ∼20% of deceased donor lungs transplanted. Diagnostic testing identifying pulmonary derangements guide donor management strategies to maximize lung transplantation. Lung ultrasound (LUS) identifies pathology in critically ill patients equivalent or superior to chest radiograph (CXR) or computed tomography (CT) scans. No published studies have reported on LUS in neurologically deceased donors (DNDDs). OBJECTIVE: We evaluated LUS in identifying abnormal lung pathology in DNDDs and related these findings to the standard approach...

Selective splenic artery embolization (SSAE) is a nonsurgical intervention characterized by the transcatheter occlusion of the splenic artery and/or its branch vessels using metallic coils or other embolic devices. It has been applied for the management of splenic trauma, hypersplenism with portal hypertension, hereditary spherocytosis, thalassemia and splenic hemangioma. We hereby describe a case of a patient affected by idiopathic thrombocytopenic purpura (ITP) and warm auto-immune hemolytic anemia (AIHA) both resistant to immunosuppressive and biological therapies, not eligible for a surgical intervention because of her critical conditions...
