Hearing the remote past seems impossible. Archaeoacoustics is a contemporary field intent on reconstructing the evolution of early communication systems, offering the possibility of developing methodologies relating to past sound signaling and music. Through a contribution of the emerging sensory field of archaeoacoustics and an example of acoustic assessments conducted at the site of Coves del Toll, can we understand signals of the past in order to investigate human behaviour and trace its cognitive evolution? This paper explores alternative methodological and theoretical approaches to understanding prehistoric sonic behaviours in early hominids and aims to set out a framework to theoretically and philosophically approach the "sound record" of the past. The theoretical proposition of this paper integrates the musical and sound art disciplines of spectralism and sound ecology to challenge the current limitations of listening to sound.

A 76-year-old man with a past occupational history as a firefighter and construction worker presented at an urgent care center with signs and symptoms of chronic dry cough, exertional dyspnea, and fatigue. His initial chest X-ray showed interstitial thickening in the middle and lower lobes with pulmonary infiltrates bilaterally. The patient was treated with an outpatient course of antibiotics.

The NLRP3 inflammasome, regulated by TLR4, plays a pivotal role in periodontitis by mediating inflammatory cytokine release and bone loss induced by Porphyromonas gingivalis. Periodontal disease creates a hypoxic environment, favoring anaerobic bacteria survival and exacerbating inflammation. The NLRP3 inflammasome triggers pyroptosis, a programmed cell death that amplifies inflammation and tissue damage.

The vascular endothelium and its endothelial glycocalyx contribute to the protection of the endothelial cells from exposure to high levels of sodium and help these structures maintain normal function by regulating vascular permeability due to its buffering effect. The endothelial glycocalyx has negative surface charges that bind sodium and limit sodium entry into cells and the interstitial space. High sodium levels can disrupt this barrier and allow the movement of sodium into cells and extravascular fluid.
