چکیده
CEP accounts for up to 2% of all cases of interstitial lung diseases and seem more frequently in females. Symptoms are generally nonspecific. Wheezing, haemoptysis and respiratory failure are rarely seen. Extra-thoracic system involvement if present, excludes a diagnosis of CEP. Diagnosis is based on; respiratory symptoms of more than 2 weeks duration, alveolar (>40% on Bronchoalveolar lavage) and/or blood eosinophilia (0.1 X109/L), pulmonary infiltrates with usually a peripheral predominance on chest imaging and exclusion of other causes of eosinophilia. The chest X-ray as in the index case, described as photographic negative of pulmonary oedema is characteristic of CEP and is seen in up to one fourth of patients.

Morphology and deflection properties of bat wing sensory hairs: scanning electron microscopy, laser scanning vibrometry, and mechanics model.
Bat wings are highly adaptive airfoils that enable demanding flight maneuvers, which are performed with astonishing robustness under turbulent conditions, and stability at slow flight velocities. The bat wing is sparsely covered with microscopically small, sensory hairs that are associated with tactile receptors. In a previous study we demonstrated that bat wing hairs are involved in sensing ai...
متن کاملRoboBat: Dynamics and Control of a Robotic Bat Flapping Flying Testbed
This paper investigates the control of the phase di erence in between three di erent motions of bat ight: pitching, apping, and lead-lag. For active control, a robotic bat test bed capable of simulating di erent wing motions is used to test the control of these wing motions and the phase di erences using central pattern generators (CPG’s). Previous work with the robotic bat is expanded upon by ...
متن کاملInertial Attitude Control of a Bat-like Morphing-wing Micro Air Vehicle
This article presents a novel bat-like micro air vehicle inspired by the morphing-wing mechanism of bats. The goal of this paper is twofold. Firstly, a modelling framework is introduced for analysing how the robot should maneuver by means of changing wing morphology. This allows the definition of requirements for achieving forward and turning flight according to the kinematics of the wing modul...

related homeobox 1 gene, Prrx1, are up-regulated in the autopods of the bat wing compared to the bat hindlimb and mouse forelimb. Changes in the mRNA transcript abundance of several genes involved in retinoic acid (RA) synthesis, degradation and signaling were consistent with the down-regulation of the RA signaling pathway in the developing bat wing autopod. Signal from a microarray probe targe...

متن کاملFalling with Style: Bats Perform Complex Aerial Rotations by Adjusting Wing Inertia
The remarkable maneuverability of flying animals results from precise movements of their highly specialized wings. Bats have evolved an impressive capacity to control their flight, in large part due to their ability to modulate wing shape, area, and angle of attack through many independently controlled joints. Bat wings, however, also contain many bones and relatively large muscles, and thus th...
