Smooth muscle hamartoma (SMH), described by Stokes in 1923, is a proliferation of smooth muscle bundles. It can be single or multiple and may be congenital and acquired.1 The most frequent presentation is the localized congenital form, which is characterized by a plaque with a variable degree of hyperpigmentation, hypertrichosis, and induration. It is usually less than 10 cm in diameter and app...

Eye contact often elicits a smiling response. We investigated whether an individual’s awareness that the recipient perceives their direct gaze during eye has influence on this Participants wore glasses with either clear or dark lenses (preventing other person from seeing eyes). Measurements of electromyographic activity zygomatic and periocular muscle regions showed responses were greater to ot...

This unprecedented research endeavors to investigate the relationship between dark personality traits (i.e., narcissism, Machiavellianism, and psychopathy) and corruption intention through the mediation of anxiety.  Based on the resource conservation theory, it is hypothesized that those higher in dark personality traits are more inclined to corrupt when they feel anxious. Having collected data...

The aim of this study was to characterize the swimming behaviour of C. intestinalis larvae during the first 6 h after hatching by measuring tail muscle field potentials. This recording method allowed a quantitative description of the responses of the larva under light and dark conditions. Three different larval movements were distinguished by their specific frequencies: tail flicks, 'spontaneou...

The role of preserving spontaneous effort during mechanical ventilation and its interaction with mechanical ventilation have been actively investigated for several decades. Inspiratory muscle activities can lower the pleural components surrounding the lung, leading to an increase in transpulmonary pressure when spontaneous breathing effort is preserved during mechanical ventilation. Thus, incre...

BACKGROUND Rhabdomyolysis is a potentially life-threatening syndrome that can develop from a variety of causes. The aim of the work is to analyze the clinical spectrum and to evaluate the prevalence of various etiologies in children, who present to the emergency department (ED) with rhabdomyolysis. METHODS During a 6-year study period, we retrospectively analyzed the medical charts of patient...

Predictable seasonal change in photoperiod triggers a sequential change in the daily activity-rest pattern, adaptive for migration in several bird species. The night-migratory black-headed bunting (Emberiza melanocephala) is day active under short photoperiods (8 h light:16 h dark, short day sensitive). Under long photoperiods (16 h light:8 h dark), the buntings are initially day active (long d...

advances, it's now possible to get an in-depth look at cellular processes. These images show three-dimensional Monte Carlo simulations of synaptic variability at the vertebrate neuromuscular junction. The simulations were created using the MCELL computer program. In the image at top right, highly convoluted synaptic membranes have been reconstructed; the cleft face of the muscle membrane is lig...
