CT-FEM of the human thorax: Frequency response function and 3D harmonic analysis at resonance.

Background And Objective: High-frequency chest wall compression (HFCC) therapy by airway clearance devices (ACDs) acts on the rheological properties of bronchial mucus to assist in clearing pulmonary secretions. Investigating low-frequency vibrations on the human thorax through numerical simulations is critical to ensure consistency and repeatability of studies by reducing extreme variability in body measurements across individuals. This study aims to present the numerical investigation of the harmonic acoustic excitation of ACDs on the human chest as a gentle and effective HFCC therapy.

Streamlining basophil activation testing to enable assay miniaturization and automation of sample preparation.

Background: Numerous studies have demonstrated the capabilities of the basophil activation test (BAT) but various parameters such as a lack of standardization and a time consuming and labor intensive workflow continue to hinder the field to fully leverage the capabilities of this technique. When pediatric patients have to be considered, an additional limitation is related to blood volume consumption.

Objectives: This work aimed at developing and characterizing a simplified and standardized whole-blood based BAT prototype procedure and at further assessing the feasibility of automating and miniaturizing the developed assay into a 96 well plate format.

Stimulus duration and diversity do not reverse the advantage for superordinate-level representations: the animal is seen before the bird.

Basic-level categorization has long been thought to be the entry level for object representations. However, this view is now challenged. In particular, Macé et al.

The role of context in remembering familar persons: insights from semantic dementia.

Semantic dementia (SD) is a progressive condition characterized by an insidious and gradual breakdown in semantic knowledge. Patients suffering from this condition gradually lose their knowledge of objects and their attributes, concepts, famous persons, and public events. In contrast, these patients maintain a striking preservation of autobiographical memory.

[Preservation of auditory function in the excision of acoustic neuroma].

Selection criteria for the preservation of auditory function during excision of acoustic neurinoma have been defined for a long time, and the means for a successful achievement of such a goal are widely known. Recruitment of special patients, for whom maintenance of an even deeply altered hearing capacity constitutes a requisite for continuation of professional work has lead us to extend indications for the pre- and retrosigmoid approaches recommended by J.M.
