Background: Accumulation of secretions in the airways of patients with an endotracheal tube and mechanical ventilation will have serious consequences.One of the most common methods of airway clearance is endotracheal suctioning.In order to facilitate discharge of airway secretion resulting in promotion of gas exchange, chest physiotherapy technique
Abstract Background Acute physical exercise, even at a very-light-intensity, potentiates prefrontal cortex activation and improves executive function.The underlying circuit mechanisms in the brain remain poorly understood, though we speculate a potential involvement of arousal-related neuromodulatory systems.Recently, our rodent study demonstrated
Abstract Background Drosophila neuroblasts (NBs) are neural stem RED SUNSET PWD cells whose maintenance relies on Notch activity.NBs proliferate throughout larval stages to generate a large number of adult neurons.Their proliferation is protected under conditions of nutrition restriction but the mechanisms responsible are not fully understood.As am
Tree-of-heaven (Ailanthus altissima) is one of the most dangerous and widespread invasive woody plant species in Europe.Despite the fact that A.altissima is in the focus of an increasing number of research projects, the impact of its mass spread on native vegetation, its diversity, and changes in soil quality are still incomplete.The current study
In Shooting Seat Stick the article the concept of generalized control of multilevel automated control system (ACS) is formulated.The procedure of optimization of the generalized control on the basis of generalization and algorithmization of hierarchical equilibrium in multilevel systems is developed.Two algorithms of control hierarchical optimizati
